Problems solved by technology

[0005] Due to the error in the thickness of each processed product before grinding and the position from the first end face of the gear to the center hole, the accumulation of these two errors will cause the axial length of the gear to be consistent after grinding one end face.

Embodiment

[0025] Example: see image 3 , the elastic grinding end surface positioning device of this embodiment is suitable for improving the processing guarantee ability of the axial length of the product shaft, and the device has:

[0026] A cylindrical main shaft seat 1, its rear end is fixedly connected in the inner hole of the grinding machine main shaft 2, and the front end extends out of the grinding machine main shaft; the grinding machine main shaft 2 is coaxially connected with the grinding machine flange 3, which is fixed on the grinding machine main shaft 2. Connected with the first driving lever 4 parallel to the axis of the main shaft seat 1, the first driving lever is used to toggle the connecting seat 20 to rotate.

[0027] An adjusting screw plug 5 is threadedly connected to the inner cavity of the rear end of the main shaft seat 1, and a sliding top 6 is coaxially connected to the inner cavity of the front end. A compression spring 7 is provided in the inner hole of t...

Abstract

The invention discloses an elastic multi-model grinding end surface positioning device. A flange of a grinding machine is coaxially rotationally connected to the outside of a spindle of the grinding machine, a first shifting lever is fixedly disposed on the flange, a spindle seat is fixedly connected into an inner hole of the spindle of the grinding machine, an adjusting plug screw is connected into an inner cavity of the rear end of the spindle seat in a threaded manner, a sliding center is coaxially connected into an inner cavity of the front end of the spindle seat, and a compression spring is arranged between the sliding center and an end surface of the adjusting plug screw. A connecting seat is in sleeve joint on the outer portion of the front end of the spindle seat, an axial positioning structure and a radial positioning structure are disposed between the connecting seat and the spindle seat, an end cover is detachably connected to the end surface of the front end of the connecting seat, a second shifting lever parallel to the first shifting lever is arranged on the end cover, a straight hole is disposed in the center of the end cover, and the front end of the sliding center can extend out of the straight hole. Central holes of a shaft are used as radial references, an end surface of a gear is used as a length processing reference, and the purpose of directly guaranteeing the axial length of the gear is achieved.

Description

Technical field: [0001] The invention relates to an elastic grinding end surface positioning device. Background technique: [0002] Oil pump gear shaft products have high requirements on the sealing effect of gear assembly, such as figure 1 As shown, the driving gear shaft A and the driven gear shaft B are a pair of parts with high requirements on the axial length of the tooth portion, and the axial length error of the tooth portion C is generally 0.01 mm. At present, the fine grinding of the two end faces of the gear is processed on the cylindrical grinding machine. The end faces on both sides of the gear are based on the center hole, and the batch difference of the axial length cannot be stably guaranteed to be within 0.01mm. [0003] see figure 2 , the characteristics of the existing two-side grinding processing method are: [0004] The spindle top 15 is a fixed top that cannot rotate and cannot be elastically stretched in the axial direction. It is installed in the i...
