БУРИЛЬНЫЙ МОЛОТОК С МЕХАНИЗМОМ ДЛЯ ПРЕДОТВРАЩЕНИЯ САМОПРОИЗВОЛЬНЫХ УДАРОВ МОЛОТКА

FIELD: drilling tools with electric drives, particularly for drilling with combined rotary and percussive action. SUBSTANCE: percussion drill comprises boring bit, case, piston member arranged behind boring bit to perform reciprocal movement, rotary drive, intermediate shaft, which performs rotational movement when drive imparts rotation to the shaft and rotary mechanism to transmit rotation from drive to boding bit. Device also has transforming mechanism, which transforms intermediate shaft rotation into reciprocal movement of the piston member. Percussion mechanism includes pane brought into engagement with piston member to transmit strokes from percussion drill to boring bit. Percussion drill has shifting member for selective preventing of rotation transmission from drive to transforming mechanism. Shifting member is actuated from outer case side to select one of at least two operation modes, namely rotor drilling mode in which only rotation is transmitted from drive to boring bit and rotary-percussion drilling mode in which rotation from drive is transmitted along with percussion drill strokes. Blocking mechanism is connected with switching member so that blocking mechanism may restrict piston from reciprocal movement only in rotary drilling mode. EFFECT: provision of drilling in rotary and rotary-percussive regimes, prevention of spontaneous impacts. 19 cl, 29 dwg ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß (19) RU (51) ÌÏÊ 7 (11) 2 258 125 (13) C2 E 21 B 6/00, B 25 D 16/00 ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2003133769/03, 19.11.2003 (72) Àâòîð(û): ÑÈÁÀÒÀ Ìèöó¸ñè (JP), ÔÓÐÓÑÀÂÀ Ìàñàíîðè (JP), ÊÀÊÈÓÒÈ ßñóõèðî (JP) (24) Äàòà íà÷àëà äåéñòâè ïàòåíòà: 19.11.2003 (30) Ïðèîðèòåò: 20.11.2002 JP 2002-337023 (45) Îïóáëèêîâàíî: 10.08.2005 Áþë. ¹ 22 C 2 2 2 5 8 1 2 5 Àäðåñ äë ïåðåïèñêè: 129010, Ìîñêâà, óë.

В редукционном валу расположен палец сцепления, скользящий вдоль оси редукционного вала. Механизм сцепления предназначен для осуществления выбора между режимами работы, соответствующими бурильному молотку и отбойному молотку. Ввод и вывод ведомого зубчатого колеса и редукционного вала из зацепления друг с другом осуществляется пальцем сцепления. Палец сцепления проходит через редукционный вал и зацепляется со сцепным участком, расположенным со стороны держателя инструмента с обеспечением блокировки вращения держателя инструмента. В режиме работы отбойного молотка можно выбрать между нейтральным положением, когда палец сцепления не зацепляется с участком зацепления, и положением блокировки вращения, когда палец сцепления зацепляется с участком зацепления и блокирует вращение держателя инструмента. В результате обеспечивается надежность переключения режимов работы бурильного молотка и уменьшаются габариты механизма переключения режимов его работы. 12 з.п. ф-лы, 5 ил.

Setting method for setting expansion anchors by means of an impact wrench

A control method of an impact wrench for setting an expansion anchor carries out a first sequence in response to a button being pressed. In a first phase, a rotary impact is repeatedly exerted on a screw element of the expansion anchor and a torque transmitted from the rotary impact to the screw head is estimated. The first phase S1 is continued until the estimated transmitted torque exceeds a threshold value specified for the expansion anchor. In a second phase, a number of rotary impacts specified for the expansion anchor are exerted on the screw head. If the button is released before the end of the first sequence, a premature release of the button and the phase in which the button was released is stored in a memory. In response to the button being pressed when a premature release is stored in the memory, a second sequence is carried which depends on the phase in which the button was previously released.

Hammer drill

Multi-mode hammer drill with shift lock

A shift bracket can be mounted on a shift rod for movement between a first, high-speed drilling mode and a second, low-speed drilling mode. Cooperating shift lock surfaces can be associated with the shift bracket and the shift rod, respectively. For example, a groove in the can create a shift lock surface on the shift rod. The shift bracket can be moved into a locked configuration where the cooperating shift lock surfaces can engage each other preventing movement of the bracket out of the high-speed drilling mode. The hammer mode can correspond to the high-speed drilling mode, but not to the low-speed drilling mode. A spring member can bias the bracket toward the locked position. An actuation member can be coupled to the shift bracket to overcome the biasing member and to rotate or perpendicularly move the bracket into an unlocked position. The actuation member can also move the shift member from the first mode to the second mode.

Multi-mode drill with mode collar

A drill includes a housing and a motor coupled to an output member by a transmission. The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.

Multi-speed drill and transmission with low gear only clutch

A multi-speed drill includes a housing with a motor including an output member. A constant mesh parallel axis transmission can be disposed in the housing and can include a high speed and low speed gears. A clutch member can be associated with the low speed gear. A conical spring can bias the low speed gear and the clutch member together for torque transfer up to a predetermined torque level. Above the predetermined level, cam surfaces between the low speed gear and the clutch member move them apart, thereby limiting torque transfer to the output spindle. In the high speed mode the torque transfer between the input pinion and the output spindle bypasses the clutch member. The maximum torque level capable of being generated at the output spindle in the high speed mode can be less than the predetermined torque level.

Multi-mode drill and transmission sub-assembly including a gear case cover supporting biasing

A multi-mode drill can include a transmission to transfer torque from an output member of a motor to an output spindle. A transmission housing encloses the transmission in an interior cavity formed by a gear case shell and a cover plate. The cover plate can be coupled to the outer shell via screws. A static shift rod can be supported at one end by the cover plate. A shift bracket can be mounted on the shift rod and biased to a mode position by a biasing member exerting a force between the shift bracket and the cover plate. A shift pin can be supported adjacent one end by the cover plate and biased to a mode position by a biasing member exerting a force between the shift pin and the cover plate. A spindle biasing member can bias the output spindle against the cover plate. The shift pin can actuate an electronic switch. A motor housing can be coupled to the transmission housing with fasteners so that the cover fasteners are not accessible.

The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.
