Sensor shell processing method

Abstract

The invention provides a sensor shell processing method, which specifically comprises the following steps: 1, a datum plane is polished on a blank; 2, a large plane is milled, a machined datum plane is established, and positioning holes A and B are drilled and milled; 3, the large plane is milled, the machined datum plane is established, holes are drilled, the positioning holes are milled, a groove and an a circular groove are milled, and chamfering is completed; 4 steps are milled by the processed datum plane and positioning holes A and B in step 3, the angle of a fixture is rotated to mill a slope and drill and bore an inclined hole; 5, the datum plane and the positioning holes are positioned to be unchanged, and a rotary processing center is provided with four shafts to complete the processing of surfaces and holes in a 90-degree direction, i.e. step surfaces are milled and holes are drilled and bored; and 6, the datum plane and the positioning holes are positioned to be unchanged, and the rotary processing center is provided with the four shafts to complete the drilling and tapping of surfaces and screw threads in a 0-degree direction. According to the sensor shell processing method disclosed by the invention, fit clearance is reduced, the position degree and the smooth finish are improved, and the precision and the sensitivity of a sensor are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of processing sensor housings, in particular to a processing method for sensor housings. [0002] Background technique [0003] The oil circuit sensor housings of aircraft engines are almost all die-cast special-shaped cast aluminum parts. There are some small holes, inclined holes, grooves and steps on them with high position accuracy and small roughness. With the increase of output, traditional boring machines, etc. The efficiency of the processing method is too low, and it cannot meet the requirements of its processing position and smoothness. [0004] Contents of the invention [0005] In order to solve the above technical problems, the present invention provides a processing method for the sensor housing, especially a processing method for complex holes on the sensor housing, which not only reduces the fit clearance, but also improves its position and smoothness. The accuracy and sensitivity of t...
