A shaft hole vertical fixed support structure

Abstract

The invention discloses a shaft hole vertical fixation supporting structure. The shaft hole vertical fixation supporting structure is characterized by comprising a diving pull rod and a supporting cylinder, wherein the diving pull rod is sleeved with the supporting cylinder; a big-end-up circular truncated cone is fixedly arranged at the upper end of the diving pull rod; the lower end of the diving pull rod penetrates out of the supporting cylinder, and a lower extending section of the diving pull rod is sleeved with a diving nut; an expansion clamping head is fixedly arranged at the upper end of the supporting cylinder, and the upper portion of the expansion clamping head is symmetrically provided with two limiting grooves; the top of the circular truncated cone is provided with a groove and a stop dog; the two ends of the stop dog are located in the two limiting grooves respectively; a guide sleeve and a compression spring are mounted on the supporting cylinder; the lower portion of the supporting cylinder penetrates through a working table and then is provided with a pull ring; the pull ring is connected with the lower end of the supporting cylinder through threads. The shaft hole vertical fixation supporting structure can stably fix a shell of a water pump, facilitate polishing of the end face of the shell through a cutter or a grinding disk and guarantee the perpendicularity of the end face and a shaft hole.

Description

technical field [0001] The invention belongs to the technical field of end face processing of a shaft hole of a pump body, and in particular relates to a vertical fixed support structure for a shaft hole. Background technique [0002] When processing the water pump casing, the verticality of the end surface and the shaft hole and the flatness of the end surface are very important. However, when processing the water pump casing, there are problems such as the verticality between the end surface and the shaft hole or the flatness of the end surface does not meet the requirements. When the end face is polished, there is a tolerance of about 0.06mm. When the end face is worn or scratched due to the subsequent processing and assembly process, the water pump shell can also be repaired. If the processing machine is used for repair or rework, the original processing machine tool needs to readjust the processing tool The stroke and part reference are very cumbersome and difficult, wh...

[0002] When processing the water pump casing, the verticality of the end surface and the shaft hole and the flatness of the end surface are very important. However, when processing the water pump casing, there are problems such as the verticality between the end surface and the shaft hole or the flatness of the end surface does not meet the requirements. When the end face is polished, there is a tolerance of about 0.06mm. When the end face is worn or scratched due to the subsequent processing and assembly process, the water pump shell can also be repaired. If the processing machine is used for repair or rework, the original processing machine tool needs to readjust the processing tool Stroke and part benchmarks are very cumbersome and difficult, which can easily cause parts to be scrapped

If it is repaired by hand, it is difficult to ensure the flatness of the processed end face and the perpendicularity of the entire end face and the shaft hole. Therefore, there is an urgent need for a device that can directly repair or rework the water pump casing, and the key technology of the device is It lies in the fixing of the shell, maintaining the vertical stability of the shaft hole and the end face, which is convenient for grinding tools or grinding discs
