DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-3 , a gear end face grinding tooling for gear processing includes a placing cross plate 1. A plurality of positioning posts 3 are fixedly connected to the upper end of the placing cross plate 1. A plurality of installation grooves 2 are formed in the upper end of the placing cross plate 1. A lifting mechanism for lifting the gears on the placing cross plate 1 is provided on the placing cross plate 1. The lifting mechanism includes a plurality of movable frames 4 arranged in a plurality of the installation grooves 2, and a first anti-slip sleeve 5 is provided on the side wall of the movable frame 4.

[0022] Below multiple movable frames 4, there is a driving mechanism for driving the movement of the movable frames 4. The driving mechanism includes two connecting plates 7 fixedly connected to the lower ends of the multiple movable frames 4. Both side walls of the two movable frames 4 are fixedly connected with fixed frames 13.

[0023] In the present utility model, both side walls of the placing cross plate 1 are fixedly connected with fixing plates 6. The upper ends of the fixing plates 6 are fixedly connected with multiple hydraulic cylinders 10. The model of the hydraulic cylinder 10 is MG-CXHC-C driving equipment, which can automatically lift the multiple movable frames 4 regularly without manual lifting.

[0024] In the present utility model, both side walls of the placing cross plate 1 are fixedly connected with limiting blocks 8. The inner walls of the limiting blocks 8 are slidably connected with fixing blocks 11. The upper ends of the fixing blocks 11 are fixedly connected with the lower ends of the adjacent connecting plates 7. The cross section of the limiting blocks 8 is U-shaped, which can position the movable frames 4 on the placing cross plate 1, so that the positions of the movable frames 4 placed in the installation grooves 2 are fixed each time.

[0025] In the present utility model, the upper ends of the fixing plates 6 are fixedly connected with a material guiding plate 9. The upper end of the material guiding plate 9 is provided with an inclined surface, which can prevent debris from accumulating on the fixing plates 6, thereby improving the practicability of the device.

[0026] In the present utility model, a plurality of through holes 12 are formed in the side walls of the fixing plates 6, which can reduce the weight of the fixing plates 6. The side walls of the fixed frames 13 are provided with second anti-slip sleeves 14, which can facilitate the grasping of the fixed frames 13.

[0027] In the initial state, the placing cross plate 1 is installed on the guide rail of the planetary gear grinding machine.

[0028] When in use, the planetary gears are sequentially pressed onto the multiple positioning columns 3 on the placing cross plate 1. After the grinding is completed, by holding the front and rear sides of the movable frame 4, the multiple planetary gears on the movable frame 4 can be simultaneously ejected from the positioning columns 3 without taking them out one by one;

[0029] For the removal of the multiple movable frames 4, by stretching the connecting plates 7 and the fixed frames 13, and by holding the fixed frames 13 on both sides, the multiple movable frames 4 can be lifted simultaneously without lifting the movable frames 4 one by one;

[0030] In addition, by starting the multiple hydraulic cylinders 10, the output ends of the hydraulic cylinders 10 stretch, which can jack up the two connecting plates 7, so that the multiple movable frames 4 can automatically rise without manual operation, thereby improving the automation degree of the device.
