Problems solved by technology

[0002] At present, after the casting middle section of the micro-car intubation type rear axle is processed, in the process of assembling components, it is often necessary to carry out multiple disassembly and assembly for various reasons, so that it is easy to cause the connecting thread on the casting middle section to be damaged. wear and tear
Even in the process of processing, the thread processing error may directly lead to the overall scrapping of the intubated rear axle or the casting middle section
In this way, not only will it be difficult to waste, but it will also cause an unreasonable increase in production costs.

Embodiment Construction

[0011] In order to solve the problem of modification of the threaded hole in the casting middle section of the microcar intubation type rear axle involved in the background technology of this application, the present invention provides a simple and low-cost microcar intubation type rear axle housing Repair method of threaded hole. The described restoration method comprises the following steps,

[0012] First check and detect the damage condition of the threaded hole that needs to be repaired, determine and drill the bottom hole with the largest diameter required for repairing the threaded hole, and then prepare the threaded female hole before repairing on the bottom hole with the largest diameter, and At the same time, prepare a threaded casing whose external thread is compatible with the threaded female hole, and whose internal thread is consistent with the threaded hole of the micro-car intubation type rear axle housing threaded hole, and finally screw the threaded casing to...

Abstract

The invention belongs to the technical field of designing and manufacturing a micro car chassis, and provides a repairing method for threaded holes of a micro car pipe inserting type rear axle housing, which is simple in operation and low in cost. The repairing method comprises the following steps of firstly checking and detecting a damage situation of the threaded holes needing to be repaired, determining and drilling a largest-diameter bottom hole which is needed during the repairing of the threaded holes, then preparing a threaded master hole in the largest-diameter bottom hole before repairing, meanwhile, preparing a threaded sleeve of which external threads are fitted with the threaded master hole and internal threads are consistent with threads of the threaded holes of the micro car pipe inserting type rear axle housing, and finally, rotationally connecting the threaded sleeve to the threaded master hole; in such a way, the repairing work on the threaded holes of the micro car pipe inserting type rear axle housing is completed until all the damaged threaded holes of the micro car pipe inserting type rear axle housing are repaired.

Description

technical field [0001] The invention relates to a repairing method, in particular to a repairing method for threaded holes of a microcar intubation type rear axle housing, and belongs to the technical field of design and manufacture of a microcar chassis. Background technique [0002] At present, after the casting middle section of the micro-car intubation type rear axle is processed, in the process of assembling components, it is often necessary to carry out multiple disassembly and assembly for various reasons, so that it is easy to cause the connecting thread on the casting middle section to be damaged. Abrasion, chaotic teeth, etc. Even in the process of processing, it is also possible to directly cause the overall scrapping of the described intubation rear axle or the casting middle section due to thread processing errors. In this way, not only will it be difficult to waste, but it will also cause an unreasonable increase in production costs. Therefore, it is of great...
