Description
Technical Field
The invention relates to the technical field of simultaneous movement unclamping processing machines, in particular to a tool changing driving device of a simultaneous movement unclamping processing machine, which can be matched with each other in an elastic size so as to be suitable for various types of machine tools and can be manufactured and assembled more simply and easily.
Background
As shown in taiwan patent No. M541922 (the following prior art symbol is referred to the former case for convenience of explanation, and the symbol description of the present case is not separately labeled, which will be described first), when changing tools, a spindle unit 2 is raised by a distance, a striking unit 4 disposed on the spindle unit 2 is raised therewith, and a driven engaging member 43 of the striking unit 4 is engaged with an engaging groove 411 of a driving member 41 of a tool changing driving device disposed on the tool changing unit 3. Thus, the driving motor 31 of the tool changing driving device links the shaft 321 to rotate the cam box driving gear 322 combined at the end of the shaft 321, and further links the cam box 33 to rotate the tool changing arm 34 to the lower side of the clamping group 22, and at the same time, the shaft 321 also links the tool releasing driving gear 323 and the tool releasing gears 325 to rotate, and then drives the tool releasing output shaft 324 and the driving member 41 combined on the tool releasing output shaft 324 to rotate through two mutually meshed bevel gears, and further drives the driven clamping member 43 and the cam member 42 to rotate, and finally the tool releasing arm 44 is pushed by the cam member 42 to swing, so as to link the clamping group 22 to release the machining tool 23, and further enable the tool changing arm 34 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 engaging member 43 is precisely engaged with the driving member 41 in a coaxial manner without any offset or eccentricity. However, the size and dimension of the striking unit 4 of each machine type are slightly different, and such slight difference often causes a problem that the driving member 41 and the driven engaging member 43 cannot be precisely engaged in a coaxial state. In addition, each component of the tool changing unit 3 and the tool striking unit 4 has a slight tolerance during manufacturing, and the tolerance often causes a problem that the driving member 41 and the driven engaging member 43 cannot be precisely engaged in a coaxial state after the assembly is completed. In the tool changing driving device of the conventional simultaneous movement unclamping machine, the connection of the gear set 32 is utilized to transmit the rotation power of the shaft rod 321 to the unclamping output shaft 324, and the structure of the gear set 32 includes the shaft rod 321 coaxially linked with the rotation shaft of the driving motor 31, the unclamping driving gear 323 combined on the shaft rod 321, the unclamping gear 325 engaged with the unclamping driving gear 323, the driving bevel gear combined coaxially with the unclamping gear 325 and the driven bevel gear engaged with the driving bevel gear and combined on the unclamping output shaft 324. Therefore, the distance between the shaft 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 various types of the striking unit 4, and the assembly is often troublesome and difficult due to manufacturing tolerances.
