Description

There is bilateral hold-down mechanism and the compressing method thereof of self adaptation function of regulating height thereof

Technical field

The present invention relates to a kind of for automobile brake pincers support processing and the hold-down mechanism of detection, have particularly to one There are bilateral hold-down mechanism and the compressing method thereof of self adaptation function of regulating height thereof.

Background technology

During automobile brake pincers support processing or detection, typically have more than one support be processed or detect, It is thus desirable to support is carried out positioning compression during brake-caliper support processing or detection.

During processing and detection, the compression to brake-caliper support is particularly important, is related to the machining accuracy of support, And the accuracy of detection data, workman can come lathe through Row sum-equal matrix according to the detection data of support, so the pressure of support Tightly producing and detection is being extremely important.

Brake-caliper support itself is blank, and many in compression to support in processing and detection I haven't seen you for ages uses black skin, And the precision of black skin itself is the highest, this adds increased support compression difficulty during processing and detection.

It is therefore desirable to provide a kind of hold down gag to solve the problems referred to above.

And brake-caliper support can find to there may be drop between the face of pressure under different workpieces pressure point in positioning compression, But without floating effect paw down pressure during may one end be depressed into a support other end may also not have down press or Not exclusively being depressed into another support, support processing and detection will be affected if compressed the most completely in processing and detection medium-height trestle Data accuracy.

Summary of the invention

The present invention is to solve defect and deficiency present in above-mentioned prior art, propose a kind of for two workpiece height There is the situation of larger difference, can preferably solve the compression problem of workpiece, guarantee that brake-caliper support in processing and detected The conforming bilateral hold-down mechanism with self adaptation function of regulating height thereof of data and compressing method thereof in journey.

The technical solution adopted for the present invention to solve the technical problems is: a kind of have the double of self adaptation function of regulating height thereof Limit hold-down mechanism, including paw, screw rod, compression point, plain washer, packing ring, butterfly spring and back-up ring, described compression point is arranged on pressure Pawl two ends, described screw rod one end is provided with spheric seat, and the screw rod other end connects piston rod and is fixed on fixture by paw, described flat Cushion, between spheric seat sphere and paw, is provided with packing ring below described plain washer, described butterfly spring is pacified by back-up ring It is contained in the lower end of paw.

The present invention uses screw rod to be connected on piston rod by paw, use simultaneously the rotatable of spheric seat and butterfly spring and , there is the situation of larger difference for two workpiece height in reset function so that paw has floatability, during pressure down, First contacting the lower pressure surface of relatively high trestle, paw, by angular force, because paw has floatability thus deflects and presses down other direction Another support, can preferably solve the compression problem of workpiece, guarantees brake-caliper support data during processing and detection Concordance.

Preferably, described paw upper center is provided with upper groove, is provided with low groove in the middle part of paw lower end, described spheric seat and Plain washer is pressed in upper groove by the head of screw rod, and described butterfly spring is pressed in low groove by back-up ring.

This kind of structure makes being more firmly mounted of spheric seat and butterfly spring reliable, so that it is guaranteed that the rotation of spheric seat is more Adding the most reliable, the compression of butterfly spring resets more steadily reliable.

Preferably, described screw rod is machined with draw-in groove, described draw-in groove is provided with the snap ring of locking back-up ring position.

This kind of structure makes being more firmly mounted of back-up ring reliable, so that it is guaranteed that firm butterfly spring is positioned of back-up ring.

Preferably, described spheric seat and plain washer assembling, screw rod is being filled with plain washer by spheric seat sphere after angular force Deflect on the face joined, thus drive screw rod to deflect, make paw have certain skewed popularity.

Preferably, the gap limiting screw rod range of deflection it is provided with between packing ring and the paw installed below described plain washer.

This kind of structure can well limit the range of deflection of screw rod, prevents from damaging paw.

Preferably, when described butterfly spring stress disappears, during recovery shape drives screw rod to return.

Butterfly spring rigidity in the present invention is big, and snubber ability is strong, can bear big load with small deformation, be suitable for axle To the occasion that space requirement is little.

Preferably, the described point that compresses compresses point for rubber.

Preferably, the compressing method of a kind of bilateral hold-down mechanism with self adaptation function of regulating height thereof, including following step Rapid:

1) paw and piston rod are coupled together by screw rod, and piston rod movement drives paw to compress or take-off the brake pincers support;

2) when pressing brake-caliper support under paw, because pressure surface injustice can allow screw rod by angular force, spheric seat and plain cushion under workpiece Circle cooperation is arranged on screw rod, decomposes the angular force pressing down generation, allows paw compress brake-caliper support;

3) there is gap between packing ring and the paw below plain washer, the gap existed preferably limits the range of deflection of screw rod, Paw may be damaged beyond this range of deflection;

4) butterfly spring that paw lower end is installed is after screw rod is by angular force, and the face that screw rod contacts with butterfly spring is defeated Contracting;

5) butterfly spring compresses recovery after distress resolves, in making screw rod return in recovery process.

Preferably, the described point that compresses uses the quality of rubber materials with certain compressibility, and brake-caliper support is appearance profile ratio Rougher blank.

Owing to brake-caliper support itself is blank, so appearance profile is relatively rough, the depth of parallelism between the dough-making powder of face is not It is fine, so the compression point of quality of rubber materials is more applicable.

The present invention is directed to two workpiece height and there is the situation of larger difference, during pressure down, first contact relatively high trestle Lower pressure surface, paw is by angular force, because paw has floatability thus another support of other direction is pressed down in deflection, can be preferably The compression problem solving workpiece, guarantee brake-caliper support concordance of data during processing and detection.
