Description

Backbone sealing ring trimmer double-pole clamping device

Technical field:

The present invention relates to backbone sealing ring overlap trimmer, relate in particular to a kind of cutter holding device that is used for ability backbone sealing ring overlap trimmer.

Background technology:

Because backbone sealing ring is generally compression molding, all there is the mold pressing overlap at the Internal and external cycle sealed lip of the sealing ring of compression molding, must carry out the deflashing finishing; The requirement of deflashing simultaneously is very high; The circularity of Internal and external cycle and axiality is very big to the influence of sealing property does not between the two reach the regulation requirement if overlap is removed, and sealing ring tightness can will be had a greatly reduced quality; Will seal failure when serious, can not normally use.At present, adopt two trimmers respectively the inner ring and the outer ring of backbone sealing ring to be cut finishing respectively in the industry usually, remove overlap.Not only need two trimmers, have high input, equipment is put and is taken up an area of greatly; Trimming process step is long; And every backbone sealing ring all will be easy to cause the Internal and external cycle decentraction through twice clamping, and promptly axiality is overproof; The machining accuracy of reinforced seal is difficult to guarantee that this deburring technology can't satisfy the processing request of high accuracy backbone sealing ring.

Summary of the invention:

The object of the invention is to provide a kind of backbone sealing ring trimmer double-pole clamping device; It can accomplish the accurate excision of Internal and external cycle lip overlap simultaneously on a trimmer; Both practiced thrift and repaiied man-hour; Omitted a trimmer again, the more important thing is that it can stablize circularity and the axiality that guarantees backbone sealing ring Internal and external cycle sealed lip.

The technical scheme that the present invention takes is:

Backbone sealing ring trimmer double-pole clamping device according to the invention; Comprise folder cutter body, connecting rod, pressing plate, bridge screw, secondary cutter grip block, secondary cutter hub, operator body, lock-screw and secondary cutter angle modulation rule; On folder cutter body, be provided with knife bar hole and fastening screw, the knife bar hole is arranged on the center of folder cutter body, and fastening screw is arranged on the side of folder cutter body; The axis in the axis of fastening screw and knife bar hole is in the same plane, and both are vertical each other; On connecting rod, be provided with the knife bar groove that the operator body is installed; Said secondary cutter grip block is made up of knife clip, gripper shoe, folder cutter groove, pressing plate retaining thread hole and connecting hole; Knife clip and gripper shoe vertical distribution; Folder cutter groove and pressing plate retaining thread hole all are arranged on the knife clip; And pressing plate retaining thread hole distributes along the both sides of folder cutter groove, and connecting hole is arranged on the gripper shoe; Secondary cutter grip block is installed on the folder cutter body through gripper shoe; Connect fixing by lock-screw; Have the angle modulation gap between the back side of knife clip and the folder cutter body side, the operator body is installed in the knife bar groove of connecting rod, and connecting rod is sleeved in the knife bar hole that presss from both sides the cutter body and is fixed by lock-screw; Secondary cutter hub is installed in the folder cutter groove of secondary cutter grip block, and is compressed through pressing plate by bridge screw; Secondary cutter angle modulation scale is arranged between the gripper shoe of folder cutter body and secondary cutter grip block.

Further, said secondary cutter angle modulation scale is made up of datum line and angle modulation rule, and datum line is arranged on the side of folder cutter body, and the angle modulation rule is arranged on the gripper shoe of secondary cutter grip block, and the angle modulation rule that the position is set is corresponding with datum line.

Owing on folder cutter body, operator body and secondary cutter hub can be installed simultaneously, can cut finishing simultaneously to the inner ring and the outer ring of backbone sealing ring, remove overlap.Make the work that needs two trimmers to accomplish in the prior art need only a trimmer and just can accomplish, not only reduced the equipment input, practiced thrift the workplace; Improved the cutting dressing efficiency of backbone sealing ring inner ring and outer ring, simplified backbone sealing ring inner ring and outer ring cutting trim process, the more important thing is; Every backbone sealing ring is in accomplishing inner ring and outer ring cutting finishing process process; As long as clamping once, can guarantee the inner ring and the outer ring axiality of backbone sealing ring, the machining accuracy of reinforced seal is improved; Adopt the present invention, for production high accuracy backbone sealing ring provides synchronous deburring technical guarantee.
