The invention mainly relates to a numerical-control machine tool feed-setting method. A feed setting method using graded code discs, which is applied to NC-plain compatible machine tools of multiple operation modes, and characterized by comprising the following steps of: inputting feed parameters (1-3) of a machine tool into a feed database (1-4) and inputting the feed database (1-4) into a special NC system (1-1) of the machine tool through a data interface (1-2); displaying the feed parameter table in matrix arrangement on the monitor in real time or indicating the feed parameter list at a notable position of the machine tool; distributing each type of feed parameters into a matrix table. The machine tool is provided with an operation panel with a plurality of graded code discs (1-6) for feed parameter selection, and all graded code discs are provided with scales each of which corresponds to a feed state or a feed value. A feed is selected after rotating a selected graded code disc (1 ...

Main axis transmission system of lower speed big torque lathe

A main shaft drive system for a low-speed large torque lathe includes an electric motor and a drive gear case. The motor is a DC motor or an AC conversion motor. The gear case is provided with a gear a, a gear b, a duplicate shifting slide gear, a gear c, a gear d, a shifting slide gear, an internal gear clutch, a gear e, a gear f, a gear g, a helical gear h, a helical gear i, a first shaft, a second shaft, a third shaft, a fourth shaft, a fifth shaft and a sixth shaft. The invention has the advantages of excellent speed regulation performance and simple structure; and the main shaft drive system can finish large torque output when at a low speed of 1 to 125rn/min. The output torque of the main shaft is large, the cutting depth is increased, the cutting quantity is enlarged and the latch processing is improved. When conducting a rough machining, the advantage can be more predominant.

Forced-feed safety protection device

The invention relates to the technical field of the safety protection mechanism suitable for various small, large and heavy lathe movement feed mechanisms, specifically to a forced-feed safety protection device. The forced-feed safety protection device comprises a motor; a power output shaft of the motor is connected with a first transmission gear by a first transmission flat key; the first transmission gear is meshed with a second transmission gear installed on a first transmission shaft; the second transmission gear is meshed with a third transmission gear installed on a second transmission shaft; the third transmission gear is connected with a indexing positioning plate by a second transmission flat key; the indexing positioning plate is fixedly connected with a copper sleeve by a fixing bolt; the copper sleeve is installed on a positioning sleeve through the interference fit; the positioning sleeve is connected with the second transmission shaft by a third transmission flat key; and ...
