Abstract
The invention relates to a cutting clamp for a universal joint retainer window. The cutting clamp comprises a fixed clamp and a movable clamp, wherein the fixed clamp is formed by connecting two concentric round plates through a screw, the circle center of one round plate is fixedly arranged on a rotating shaft of a servo motor, a screw hole is formed in the circle center of the other round plate, a through hole is formed in the circle center of the movable clamp, and a bolt penetrates through the through hole of the movable clamp and is matched with the screw hole of the fixed clamp through a screw thread; an adjustable radial compaction device for radially clamping and positioning a retainer is arranged between the two round plates of the fixed clamp, and the retainer rotates at a set angle by the servo motor, so that cutting of the circumferential retainer window is implemented. The cutting clamp is suitable for clamps of retainers of all kinds of specifications, and has the advantages of simplicity and convenience in clamping, no clamp abrasion, avoidance of maintenance, high processing efficiency, low processing cost, good window processing precision and the like.
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, there is provided 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 the universal joint retainer window cutting clamper of laser cutting parameter.
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 electromagnetic mechanism 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; Electromagnetic mechanism is made up of solenoid and bar magnet, and bar magnet is arranged on solenoid inner chamber, and two compact heap back sides are fixedly connected with one end of bar magnet in one of them electromagnetic mechanism separately.
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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 stationary fixture, 2 floating holders, 3 bolts, 4 retainers, 5 compact heaps, 6 electromagnetic mechanisms, 7 radial grooves.
Detailed description of the invention
Universal joint retainer window cutting clamper as shown in Figure 1, comprise stationary fixture 1 and floating holder 2, stationary fixture 1 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 2 is shaped with through hole, and bolt 3 is connected with the screw threaded engagement of stationary fixture 1 through the through hole of floating holder 2, adjustable radial compaction device is provided with between two pieces of circular flat boards of stationary fixture 1, described adjustable radial compaction device adopts compact heap 5 and electromagnetic mechanism 6 to form, compact heap 5 has two, be arranged in radial groove 7 made on circle flat board that stationary fixture 1 contacts with retainer 4, two compact heaps 5 are equal from the distance in the dull and stereotyped center of circle of circle, the working face of compact heap 5 is positioned at the plane of the circular flat board of stationary fixture 1 and retainer 4 contact side, the working face of described compact heap 5 is the contact surface between compact heap 5 and retainer 4, compact heap 5 can radially slide by chute 7, install at the circular dull and stereotyped axial restraint of stationary fixture 1, electromagnetic mechanism 6 has two, is made up of solenoid and bar magnet, and bar magnet is arranged on solenoid inner chamber, and two compact heap 5 back sides are fixedly connected with one end of bar magnet in one of them electromagnetic mechanism 6 separately.When the solenoid is activated, bar magnet promotes compact heap 5 and is clamped by retainer 4, realizes the cutting of laser instrument to retainer 4 window, and after having cut a window, servomotor is according to setting rotation angle, and laser instrument carries out the cutting of next window to retainer 4.
Compact heap 5 working face has arc structure, and compact heap 5 working face adopts nonmetallic materials.
Clamp 5 pairs of retainers 4 can adopt and inwardly clamp from periphery, also can adopt and outwards strut compression from inner circle.Solenoid controlled power supply is provided by controlling organization.Compact heap 5 can adopt two or more, and its quantity can be determined according to the diameter of retainer 4.
