Description

Tool change drive device of simultaneous cutting machine

technical field

The present invention relates to the technical field of a simultaneous-moving knife processing machine, in particular to a knife-cutting unit that can be used for elastic dimensional matching and is suitable for various models, and can make the production and assembly simpler and easier to assemble. Tool change drive for processing machines.

Background technique

Existing known simultaneous knife processing machines, as shown in Taiwan Announcement No. M541922 Patent (the following prior art symbols are marked with the original labels of the previous case for the convenience of description, please refer to the previous case directly, so in this case The symbol description will not be marked separately, this will be explained first), when changing the tool, the pioneer makes the spindle unit 2 rise a distance, so that the tool punching unit 4 arranged on the spindle unit 2 rises with it, and then makes the punching unit 2 rise. The driven clamping member 43 of the knife unit 4 is relatively engaged with the clamping groove 411 of the driving member 41 of the driving member 41 of the tool-changing driving device provided on the tool-changing unit 3 . In this way, the drive motor 31 of the tool change driving device drives the shaft 321 to rotate the cam box drive gear 322 combined with the end of the shaft 321 , and then drives the cam box 33 to make the tool change arm 34 rotate. When rotating to the bottom of the clamping group 22, the shaft 321 will also rotate in conjunction with the unclamping drive gear 323 and the unclamping gears 325, and then drive the unclamping output shaft 324 and The driving member 41 coupled to the unclamping output shaft 324 rotates, thereby driving the driven clamping member 43 and the cam member 42 to rotate, and finally the unclamping arm 44 is pushed by the cam member 42 and swings to connect The clamping group 22 is moved to release the machining tool 23 , and then the tool changing arm 34 is used to change the machining tool 23 .

In order to smoothly transmit the power of the driving motor 31 to the cam member 42 , the driven clamping member 43 needs to be precisely engaged with the driving member 41 in a coaxial state without any offset or eccentricity. However, there are slight differences in the dimensions and sizes of the punching units 4 of various models, and these slight differences often cause the problem that the driving member 41 and the driven clamping member 43 cannot be precisely locked into a coaxial state. In addition, each component of the tool changing unit 3 and the tool beating unit 4 has a slight tolerance during manufacture, and this tolerance often causes the driving member 41 and the driven card to be caused after the assembly is completed. The problem that the device 43 cannot be accurately snapped into the coaxial state. Because the gear set 32 is used in the tool change drive device of the known synchronous tooling machine to transmit the rotational power of the shaft 321 to the tool release output shaft 324, the gear set 32 is structured to include the same gear set 32. The shaft is linked to the shaft 321 of the rotating shaft of the drive motor 31 , and the tool release drive gear 323 is combined with the shaft rod 321 , and the tool release gear 325 meshed with the tool release drive gear 323 is combined with the tool release gear 325 . The drive bevel gear of the shaft and the driven bevel gear meshed with the drive bevel gear and combined with the tool release output shaft 324 . Therefore, the distance between the shaft rod 321 and the unclamping output shaft 324 and the height of the unclamping output shaft 324 are fixed and cannot be adjusted. Therefore, it cannot be applied to the punching unit 4 of various models, and it is often more troublesome and difficult to assemble due to the manufacturing tolerance.
