DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the drawings required for the implementation are briefly introduced below. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0024] Combination Figure 1-Figure 6 As shown, the utility model provides an automatic feeding device for a gear hobbing machine, comprising a feeding mechanism 1 and a processing mechanism 2. The feeding mechanism 1 is used for feeding a workpiece, and the processing mechanism 2 is used for processing the workpiece.

[0025] According to one embodiment of the utility model, the feeding mechanism 1 includes a workbench 3 and a conveying chain 4 arranged on the workbench 3, a plurality of quick-change tooling 5 are arranged on the conveying chain 4, and a lifting station is also provided on the workbench 3, and a chain fixing structure 6 and a lifting mechanism 7 are provided at the lifting station.

[0026] The automatic feeding device for gear hobbing machine of the utility model can realize the rapid replacement of tooling of different specifications through the above-mentioned structural setting, and effectively improve the processing efficiency. The setting of the chain fixing structure 6 can ensure the stability of the lifting structure 7 when lifting the quick-change tooling 5.

[0027] The following is a detailed description of the automatic feeding device of the gear hobbing machine of the utility model:

[0028] According to an embodiment of the utility model, the quick-change tool 5 includes a tool base plate 51 and a tool base 52 disposed on the tool base plate 51. The tool base 52 is provided with a mounting groove 53, and a side wall of the tool base 52 is also provided with an indexing pin 54, which passes through the tool base 52 and is connected to the mounting groove 53. The mounting groove 53 is used to install a tool table 55, and a fork structure 56 is also provided on the tool base plate 51.

[0029] When installing the tooling table 55, the automatic feeding device for the gear hobbing machine of the utility model can pull out the indexing pin 54, put the tooling table 55 into the installation groove 53, and loosen the indexing pin 54 to complete the installation of the tooling table 55. In this way, the tooling table adapted to different workpieces can be quickly replaced as needed, and it is only necessary to ensure that each tooling table is provided with a slot hole matched with the indexing pin 54.
