[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0019] The first implementation method:
[0020] Figure 1-3The invention discloses a gear processing fixture for a gearbox, comprising a mounting base 1, one side of the upper surface of the mounting base 1 is rotatably connected with an adjusting pillar 2, the other side of the upper surface of the mounting base 1 is fixedly mounted with an electric telescopic rod 5, the top of the adjusting pillar 2 is fixedly connected with a material placing disc 4, the center of the upper surface of the material placing disc 4 is provided with a material placing groove, the bottom of the outer surface of the adjusting pillar 2 is fixedly connected with an adjusting gear 3, the telescopic end of the electric telescopic rod 5 is fixedly connected with a driving tooth plate 6, the driving tooth plate 6 is meshed with one side of the adjusting gear 3, a servo motor 7 is fixedly mounted at the center of the upper surface of the mounting base 1, and the servo motor 7 is fixedly mounted at the center of the upper surface of the mounting base 1. The output end at the top of the machine 7 is fixedly connected with an adjusting disc 8, and a first adjusting block 12 is fixedly arranged on one side of the top of the adjusting disc 8. A limited connecting plate 9 is fixedly connected to the upper surface of the mounting substrate 1 near the servo motor 7. A limited sliding groove 13 is arranged at the center of the upper surface of the limited connecting plate 9. The internal sliding connection of the limited sliding groove 13 is connected to a limited sliding block 14. A second adjusting block 15 is fixedly arranged on the upper surface of the limited sliding block 14. A driving connecting rod 16 is sleeved between the first adjusting block 12 and the second adjusting block 15. A close connecting rod 17 is fixedly connected to one side of the limited sliding block 14. The upper surface of the mounting substrate 1 is near the limited connecting plate 9. A proximity switch 10 is fixedly installed, the proximity connecting rod 17 is directly opposite to the detection end position of the proximity switch 10, and the electric telescopic rod 5 is electrically connected to the proximity switch 10; when processing the gear teeth, the gear workpiece to be processed is placed in the material placement groove on the upper surface of the material placement disc 4, so that the lower layer of the gear workpiece contacts the upper surface of the material placement disc 4, and the material placement disc 4 is placed below the milling cutter so that the edge of the upper layer of the gear workpiece is directly opposite to the position of the milling cutter. When the gear teeth are inserted, the servo motor 7 is turned on, and the servo motor 7 drives the adjusting disc 8 to rotate, and the adjusting disc 8 makes a regular circular rotation, and the first adjusting block 12 is driven by the adjusting disc 8. The first adjusting block 12 drives the limit slider 14 to make a linear reciprocating motion by driving the connecting rod 16.
