Sensor QS-4 elastomer processing technology

Technical field

The present invention relates to sensor base weighing apparatus elastomer processing technology, particularly sensor QS-4 elastomer processing technology.

Background technology

Elastomer is one of requisite critical piece of sensor, and the quality of elastomer crudy directly has influence on the performance of sensor.At present, in the QS-4 elastomer processing technology when CNC milling machine processing square hole, most processing technology that adopts aperture and baseplane one-pass to finish, like this elastomer baseplane fineness can appear and aperture fineness is poor especially, can only adopt hard polishing mode that the baseplane, hole is polished smooth then, product square hole baseplane after the result processing forms comparatively serious spill, causes the sensor stability made relatively poor, influences product quality.

Summary of the invention

The object of the present invention is to provide a kind of solution square hole baseplane spill problem, the higher sensor of the product quality of being produced QS-4 elastomer processing technology.

The technical scheme that realizes the object of the invention is: sensor QS-4 elastomer processing technology, adopt the following step:

A) mill, forward and backward, the upper and lower four sides of sanding blank, mill left and right end face;

P) smart square hole baseplane and the wall thrown.

The sensor guarantees the surface smoothness 3.2 of circular arc with among the step c of QS-4 elastomer processing technology during the circular arc of finish-milling stage casing.

When the step g finish-milling square hole of the sensor usefulness QS-4 elastomer processing technology and step, with R10 millimeter milling cutter finish-milling square hole aperture and step, square hole bottom surface wall thickness stays 0.3 millimeter surplus finish-milling, and square hole baseplane and aperture cannot be finished under the one-pass; Can throw with 20 millimeters rods of Φ earlier during step h polishing square hole baseplane polishing, and then throw the edges of square holes, avoid square hole bottom surface formation matrix and flatness is overproof with 10 millimeters thin rods of Φ.

The sensor step k heat treatment requirements hardness 43-46HRC of QS-4 elastomer processing technology.

It is 0.8 that the sensor should be controlled each surperficial roughness with the step n correct grinding outer surface of QS-4 elastomer processing technology.

The sensor is 0.01～0.012 millimeter with the step o chemical nickel plating on surface requirement thickness of coating of QS-4 elastomer processing technology.

The sensor uses 180# sand paper with the polishing of square hole baseplane on polishing machine with the step p smart throwing square hole baseplane and the wall of QS-4 elastomer processing technology, can throw with 20 millimeters rods of Φ earlier during polishing, and then throw the edges of square holes with the thin rod of 10 millimeters of Φ, avoid the square hole bottom surface to form matrix and flatness is overproof.

The advantage that the present invention has: in the elastomer processing technology, the square hole process is progressively finished by procedure of processings such as thick, finish-milling, polishings, and in the end a step is carried out the essence throwing, avoid the square hole bottom surface to form matrix and flatness is overproof, improved product quality, solve square hole baseplane spill problem, have advantages of high practicability.
