Abstract
The invention relates to a cutting clamp for universal joint retainer windows. The clamp comprises a fixed clamp and a movable clamp, the fixed clamp is mainly formed by connecting two concentric circular panels through screws, wherein the circle center of one of the circular panels is fixedly arranged on a rotating shaft of a servo motor, a screw hole is formed in the center of the other circular panel, a through hole is formed in the center of the movable clamp, and a bolt passes through the through hole of the movable clamp and is in screw thread fit with the screw hole of the fixed clamp; an adjustable radial compressing device is arranged between the two circular panels of the fixed clamp, a retainer is clamped in the radial direction to be located and rotated at a set angle through the servo motor, and the cutting of circumference windows of the retainer is achieved. The cutting clamp for the universal joint retainer windows can be applicable to clamps of retainers in various dimensions, and the cutting clamp has the advantages that the clamping is simple and convenient, no abrasion occurs to the clamp, the maintenance is not needed, the processing efficiency is high, the processing cost is low and the processing accuracy of the windows is great.
Description
Technical field
The present invention relates to the machining tool fixture of auto parts and components, specifically about universal joint retainer window cutting tool
.
Background technology
Retainer is rzeppa joint vitals, and universal joint retainer is made up of inside and outside spherical surface and two planes, is shaped with six windows at the sphere even circumferential of two plane middles
.at present, the processing of universal joint retainer window, be generally adopt traditional artificial Presser Dashing hole forming, each hole needs through twice punching press, once grinding process, is rush window forming hole for the first time, and second time rushes window size hole, then carries out grinding
.its major defect is: the retainer of different size needs different moulds, and number of molds is huge, and mould use procedure exists wearing and tearing, and produce dimensional discrepancy, need often to adjust, safeguard, processing cost is high, generation efficiency is low, affects machining accuracy; The window punching press joint-cutting depth of parallelism is poor, joint-cutting and surperficial perpendicularity poor, incision size low precision, processing technology is complicated
.
Summary of the invention
The object of the invention is to there is shortcoming for prior art, provide that a kind of clamping is simple and convenient, fixture without wearing and tearing, non-maintaining, working (machining) efficiency is high, processing cost is low, window good processing accuracy, for laser cutting parameter
universal joint retainer window cutting clamper.
Technical scheme of the present invention comprises stationary fixture and floating holder, mainly stationary fixture is connected to form by dull and stereotyped to be ordered by spiral shell of two pieces of concentric circles, wherein one piece of circular dull and stereotyped center of circle is fixedly mounted in servomotor rotating shaft, the circular dull and stereotyped center of circle of another block is shaped with screw, the center of circle of floating holder is shaped with through hole, and bolt is through the through hole of floating holder and the screw threaded engagement of stationary fixture; Adjustable radial compaction device is provided with between two pieces of circular flat boards of stationary fixture, described adjustable radial compaction device adopts compact heap and cylinder composition, compact heap has two, be arranged in radial groove made on circle flat board that stationary fixture contacts with retainer, two compact heaps are equal from the distance in the dull and stereotyped center of circle of circle, the back side of each compact heap is fixedly connected with the piston rod end of one of them cylinder, and the cylinder body of cylinder is fixedly mounted between the circular flat board of stationary fixture two
.
In above technical scheme, compact heap working face has arc structure
.
Advantage of the present invention is the circular dull and stereotyped composition retainer jig for laser cutting of employing two pieces, retainer is installed between stationary fixture and two plate level of floating holder, radial compression by compact heap is located, servomotor is according to set angle rotary holder, the cutting of retainer window is realized by laser cutting machine, by regulating the radial position of compact heap, go for the fixture of all size retainer, its clamping be simple and convenient, fixture without wearing and tearing, non-maintaining, working (machining) efficiency is high, processing cost is low, window good processing accuracy
