Problems solved by technology

At present, in the QS-4 elastomer processing technology, when machining square holes with CNC milling machines, the processing technology of the aperture and the bottom plane is mostly used in one pass. The hard polishing method polishes the bottom plane of the hole smoothly, and as a result, the bottom plane of the square hole of the processed product forms a serious concave shape, which leads to poor stability of the sensor made and affects product quality

Embodiment 1

[0036] See Figure 1 to Figure 6, a QS-4 elastomer processing technology for sensors, the blank is made of 65mm*78mm section steel, and the saw length is 265mm; the following steps are adopted:

[0037] a) Milling and grinding the front, back, upper and lower sides of the blank. When grinding the third side, square tooling should be used to ensure that the error of the square on the four sides is within 0.02mm; mill the left and right end faces to control the angle between the end face and the long face Within 0.05mm;

[0038] b) Remove the burr on the outer edge, and it is required not to affect the processing of the subsequent process;

[0039] c) Rough and fine milling of arc 1 in the middle section. When milling, use a dividing head and clamp it with QS-4 special tooling. First, rough mill arc 1 in the middle section, leaving a margin of 0.3 mm and then do a fine milling to ensure the circle in the middle section Arc 1 has a finish of 3.2;

[0040] d) Step 2 on the millin...

Abstract

The invention which relates to a processing craft of a sensor-used QS-4 elastomer adopts the following steps: a) milling and grinding a front surface, a back surface, an upper surface and a lower surface of blank materials, and milling a left end surface and a right end surface; b) deburring external edges; c) rough milling and finish milling an arc on the middle part; d) milling bottom surface steps; e) reaming holes and chamfering; f) drilling pre-manufactured holes in square holes; g) rough milling and finish milling the square holes and steps; h) polishing the bottom surface of the square holes; i) drilling small holes in the square holes and chamfering; j) drilling threading holes and tapping; k) heat treating; l) polishing the arc on the middle part; m) chamfering edges; n) finish grinding the whole external surface; o) plating electroless nickel on surfaces; p) finish polishing the bottom surface of the square holes and wall surfaces. In the processing craft of the elastomer of the invention, the square processing is completed gradually through the processing steps of rough milling, finish milling, polishing, etc., and the finish milling is done at the last step, thus avoiding the flatness oversize caused by a concave formed on the bottom surface of the square holes, improving the product quality, solving the concave problem on the bottom surface of the square holes, and having higher practicability.

Description

technical field [0001] The invention relates to the processing technology of the elastic body used for the sensor matrix scale, in particular to the processing technology of the QS-4 elastic body used for the sensor. Background technique [0002] The elastomer is one of the essential components of the sensor, and the processing quality of the elastomer directly affects the performance of the sensor. At present, in the QS-4 elastomer processing technology, when machining square holes with CNC milling machines, the processing technology of the aperture and the bottom plane is mostly used in one pass. The hard polishing method polishes the bottom plane of the hole smoothly, and as a result, the bottom plane of the square hole of the processed product forms a serious concave shape, which leads to poor stability of the sensor and affects product quality. Contents of the invention [0003] The object of the present invention is to provide a QS-4 elastic body processing technolo...
