Embodiment
Contrast accompanying drawing below,, the embodiment of the utility model is done further detailed explanation through description to optimum embodiment.
To shown in Figure 4, said ball pin clamping chuck comprises pull bar 1 like Fig. 1; Pull bar 1 is provided with the mounting hole 2 that is used to install ball pin 6 bulbs, and mounting hole 2 is a through hole, and mounting hole 2 one ends are opening end; On the other end of mounting hole 2, be provided with cover plate 5; In mounting hole 2 opening ends, be provided with ball pin 6 bulbs adaptive universal and buckle 3, universal button 3 one sides are provided with return spring 4 in mounting hole 2, return spring 4 two ends be resisted against respectively universal buckle 3 and cover plate 5 on.
Universal the buckle 3 one end outer surfaces adaptive with ball pin 6 bulbs are the conical surface; Accordingly; With mounting hole 2 internal surfaces of universal button 3 cone match be the conical surface; The conical surface of mounting hole 2 internal surfaces constitutes guiding groove, and guiding groove is near an end diameter of the mounting hole 2 opening ends the other end less than guiding groove, and guiding groove has the effect of tightening up to universal button 3 like this; Universal 3 one ends of buckleing that cooperate with ball pin 6 bulbs can move up and down along guiding groove, and universal button 3 can be stuck on the end of guiding groove near opening end after moving on the guiding groove; For guaranteeing ball pin 6 bulbs universal the button in 3 of can packing into fast, mounting hole 2 opening ends are open horn strucutre from inside to outside, and the little head end and the guiding groove of mounting hole 2 opening ends join; Ball pin 6 bulbs can be fast get in the mounting hole 2 from the opening end of mounting hole 2 like this, and then assemble with universal button 3; The guiding groove of mounting hole 2 internal surfaces and the horn strucutre of mounting hole 2 opening ends make mounting hole 2 for the cone shape hole structure simultaneously, can reduce requirement on machining accuracy.
For making ball pin 6 bulbs quick for installation, functional reliability is higher after the installation, on universal button 3, is provided with opening slot 7; The spherical groove center is a through hole, and opening slot 7 is extended by the edge of mind-set spherical groove one side in the spherical groove, and promptly 7 of opening slots are arranged on the side of spherical groove; Opening slot 7 makes universal button 3 have elasticity; Universal button 3 can open under the effect of extruding force, makes ball pin 6 bulb maximum diameters can snap in universal the button in 3 the spherical groove, and universal button 3 is after removing active force; Can tighten up, universal button 3 can pack tightly ball pin 6 bulbs.
For when assembling, universal button 3 has enough spaces to move down, and then makes universal button 3 have enough Free up Memories; Ball pin 6 bulb quick card are gone in the sphere groove, and return spring 4 is the turriform spring, and the turriform spring can be pressed into a plane; And then make universal button 3 that enough space-load distendings that moves down arranged; Can make behind the turriform spring return and universally buckle 3 and tighten up fast that make ball pin 6 bulbs to deviate from, functional reliability is good.
The clamping chuck that cooperates with ball pin 6; Universal button 3 and return spring 4 are packed into from mounting hole 2 one ends behind the mounting hole 2, and spherical groove one end adaptive with ball pin 6 bulbs is stuck in the guiding groove place, again at mounting hole 2 loam cake upper cover plates 5; Mounting hole 2 peripheries are provided with the depressed installation step on pull bar 1; After cover plate 5 was placed on the installation step, cover plate 5 was connected through the Ultrasonic Plastic Welding technology with pull bar 1, and processing is more prone to like this; Universal button 3 has polyformaldehyde material to be made.
The clamping chuck that cooperates with ball pin 6 and the fit of ball pin 6 are: ball pin 6 bulbs at first get into from the opening end of mounting hole 2; On ball pin 6 bulbs, apply an active force; Ball pin 6 bulbs contact with universal 3 the spherical groove buckled; Simultaneously, universal button 3 guiding groove in the mounting hole 2 of the effect lower edge of power moves down and compression retracteding position spring 4; Because universal button 3 itself has elasticity, universal button 3 when moving down, universal button 3 stressed distendings; Ball pin 6 bulbs can snap in the spherical groove easily and fast, after ball pin 6 bulbs snap in spherical groove, remove being applied to the active force on the ball pin 6; Universal button 3 moves on the guiding groove in the mounting hole 2 of the effect lower edge of return spring 4, and universal 3 one ends of buckleing that cooperate with ball pin 6 bulbs are along moving the back chucking on the guiding groove, and universal button 3 shrinks simultaneously; Ball stud is taken off more outward; Universal button 3 can close up more, and ball pin 6 bulbs are difficult drop-off in use, and functional reliability is good; Owing to ball pin 6 bulbs and universal mode of buckleing the little Spielpassung of 3 spherical grooves, ball pin 6 can rotate flexibly, is not easy stuck simultaneously; The clamping chuck convenience quick for installation that cooperates with ball pin 6, efficiency of assembling is high, and assembly cost is low.
Above the utility model has been carried out exemplary description; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
