[0002] CNC gear hobbing machine is a machine tool used for gear processing. It can perform precise cutting according to the path set by the program. It is suitable for batch, small batch and single piece production and processing of cylindrical gears and worm gears, as well as drum gears with certain parameters.

[0003] At present, when the gear hobbing process is performed on the camshaft transmission gear disc, the camshaft is mostly clamped to the clamping mechanism of the gear hobbing machine by a robot arm, and then the gear hobbing process is performed by the gear hobbing machine.

[0004] However, when the robot arm places the camshaft to be processed on the clamping mechanism of the gear hobbing machine, it needs to wait for the clamping mechanism of the gear hobbing machine to clamp it. The robot arm can only withdraw after the clamping mechanism of the gear hobbing machine firmly clamps the camshaft to be processed, which causes the robot arm to spend waiting time and affects the operating efficiency of the robot arm.

[0029] like Figure 1-Figure 3 As shown, a gear hobbing machine feeding device of the utility model comprises a mechanical arm 1 and a feeding mechanism, wherein the mechanical arm 1 is used to transfer a camshaft 3 to be processed to the feeding mechanism, and to transfer the processed camshaft 3 on the feeding mechanism.

[0030] The feeding mechanism includes a feeding member 21 and a driving member 22 installed on the housing of the gear hobbing machine 4. The driving member 22 is a servo drive motor, and the driving member 22 is used to drive the feeding member 21 to rotate. Specifically, the feeding member 21 includes a connecting rod 221 and a plurality of feeding plates 222. The connecting rod 221 is fixedly connected to the output shaft of the servo drive motor, and the plurality of feeding plates 222 are fixedly connected to the connecting rod 221. The feeding plate 222 is used to receive the camshaft 3 and transfer the camshaft 3 to the clamping mechanism 41. In this embodiment, the feeding plate 222 includes a base plate 51 and a support plate 52. The base plate 51 and the connecting rod 221 are integrally formed. A mounting groove 511 is provided on the base plate 51, and a mounting ear 521 is provided on the support plate 52. The mounting ear 521 is fixedly installed in the mounting groove 511 by a fixing bolt, so as to realize the detachable connection between the support plate 52 and the base plate 51. A through hole 522 is provided on the support plate 52, and the through hole 522 is used to limit the camshaft 3 on the support plate 52. By replacing the support plate 52 with through holes 522 of different sizes, the camshafts 3 of different sizes can be adapted. In some other embodiments, the through hole 522 may not be provided, and the camshaft 3 may be directly placed on the loading plate 222 for transfer, or a fixing column or the like may be provided on the loading plate 222 to fix the camshaft 3. In this embodiment, by providing the through hole 522, the camshaft 3 can be directly inserted into the through hole 522, so as to limit the camshaft 3, which is simple and convenient.

[0031] In this embodiment, the loading plate 222 is provided with a tapered groove 523 at the top of the through hole 522 , so as to facilitate the bottom of the camshaft 3 to be smoothly inserted into the through hole 522 .

[0032] In this embodiment, the feeding mechanism also includes an installation box 23, which is fixedly connected to the housing of the gear hobbing machine 4 by fixing bolts. The servo drive motor is fixedly installed in the installation box 23. An axial hole is opened on the installation box 23, and the connecting rod 221 passes through the axial hole and is fixedly connected to the output shaft of the servo drive motor.

[0033] It should be noted that in this embodiment, three loading plates 222 are provided, and a loading station, a discharging station and a processing station are provided at the loading part 21. The loading station is the position where the robot arm 1 transfers the camshaft 3 to be processed to the loading part 21, and the discharging station is the position where the robot arm 1 transfers the processed camshaft 3 from the loading part 21. The processing station is the position where the clamping mechanism 41 performs gear hobbing on the camshaft 3. The three loading plates 222 correspond to the loading station, the discharging station and the processing station respectively. The robot arm 1 is provided with a discharging chuck 11 and a picking chuck 12. The loading plate 222 located at the processing station corresponds to the clamping mechanism 41 of the gear hobbing machine 4, the loading plate 222 located at the loading station corresponds to the discharging chuck 11, and the loading plate 222 located at the discharging station corresponds to the picking chuck 12. The robot arm 1 can perform unloading and loading operations simultaneously, and there is no need to first unload the processed camshaft 3 on the loading plate 222 and then transfer the unprocessed camshaft 3 to the loading plate 222 , thereby further improving the operating efficiency of the robot arm 1 .

[0034] The method of using the utility model is as follows:

[0035] When loading the gear hobbing machine 4:

[0036] First, the robot arm 1 works and takes the unprocessed camshaft 3 from the rack through the unloading chuck 11;

[0037] Secondly, the robot arm 1 works to transfer the unprocessed camshaft 3 to the top of the loading plate 222 at the loading station; at the same time, the unloading chuck 11 is located above the loading plate 222 at the unloading station;

[0038] Then, the robot arm 1 works to insert the unprocessed camshaft 3 into the through hole 522 of the loading plate 222 from top to bottom; at the same time, the material removal chuck 12 moves from top to bottom to insert the top of the processed camshaft 3 into the material removal chuck 12;

[0039] Then, the robot arm 1 works, the unloading chuck 11 releases the unprocessed camshaft 3 , and the picking chuck 12 clamps the processed camshaft 3 and moves upward under the control of the robot arm 1 , so that the processed camshaft 3 is separated from the loading plate 222 .

[0040] Finally, the robot arm 1 works to transfer the processed camshaft 3 to the next device for processing, and the servo drive motor works to drive the loading plate 222 to rotate through the connecting rod 221, and rotates the loading plate 222 of the loading station to the processing station, waiting for the clamping mechanism 41 to clamp the camshaft 3 and then perform gear hobbing. The loading plate 222 of the original processing station carries the processed camshaft 3 to the unloading station so that it can be taken away by the material removal chuck 12 for transfer.
