Description of drawings
Fig. 1 is the structural representation of prior art clamping device;
Fig. 2 is the schematic appearance of the clamping device of part of the present utility model;
Fig. 3 is the cross-sectional schematic of described clamping device.
The specific embodiment
Below in conjunction with the specific embodiment and Figure of description thereof, the utility model is further specified.
As shown in Figure 2 to Figure 3.A kind of clamping device 200 of part, comprise main body 21 and be located at alignment pin 22 on this main body 21, this main body 21 comprises that one has the fixed mounting 211 of worker's shape through hole, is equipped with a guide post 23 in fixed mounting 211, suit one compression spring 24 on the guide post 23; Clamping device 200 also comprises clamp 25, and these clamp 25 usefulness fulcrum posts 26 are fixedly mounted on the main body 21; 24 power transmissions of compression spring are rotated described clamp 25.Clamp 25 comprises that one is used for the outer end 251 of clamping object and relative the inner 252 thereof, the both sides of described outer end 251 and the described fulcrum post 26 in described inner 252 offices.Inner 252 hinges connect a slide block 27, and described slide block 27 is socketed in the outside that is positioned at described compression spring 24 on the described guide post 23.
The utility model one preferred implementation is that this clamping device 200 also comprises line transmission mechanism 28 always.Straight-line transmitting actuation mechanism 28 comprises a cylinder 281 and its corresponding piston 282.This piston 282 is fixed on the main body 21, and moving of piston 282 can drive moving of alignment pin 22, and this piston 282 can be to be fixed on the main body 21 by a plate 29.The transmission direction of straight-line transmitting actuation mechanism 28 and alignment pin 22 towards being consistent.This alignment pin 22 towards with guide post 23 guiding vertical mutually.The two ends of guide post 23 can expose to main body 21, are spirally connected to be fixed on the main body 21.
The concrete motion process of the utility model clamping device is: straight-line transmitting actuation mechanism 28 is opened stroke, piston 282 is pushed ahead, after the stroke of straight-line transmitting actuation mechanism 28 uses up, decide firmly to sell 22 and reach the position that needs, insert in the hole in the mounting bracket 3, then mounting bracket 3 welding are finished, then, 28 withdrawals of straight-line transmitting actuation mechanism are withdrawn into initial state with whole device.
The operation principle of the utility model clamping device is: when no mounting bracket 3, because the effect of compression spring 24 compression stresses, promote clamp 25 around fulcrum post 26 rotations, make front end 251 toward the motion outward of interior rear end 252, in the time of when moving to certain position, fixed mounting 211 can limit the rear end 252 of clamp 25 and continue motion; When mounting bracket 3, the operator puts into mounting bracket 3 with hand along the curved surface of clamp 25, this moment, the operator can give 25 1 outside thrusts of clamp, clamp 25 rotates around fulcrum post 26, the rear end 252 extruding compression springs 24 of clamp 25, compressed compression spring 24 is just given 25 1 outside compression stresses of clamp, makes clamp 25 clamp mounting bracket 3 tightly.
The utility model adopts the compression spring to produce an outside compression stress when being compressed, and clamps by the dual-side of this compression stress with mounting bracket, adopts an alignment pin that the hole site of mounting bracket is fixed simultaneously.The compression stress of compression spring is determined according to the mounting bracket structure.Must from alignment pin, take out after the mounting bracket welding is finished, therefore adopt cylinder to drive the interference of alignment pin motion can not causing alignment pin and part.In order to reduce the locus, alignment pin tightens with a holding screw.
The utility model can be used for proving that by actual production the welding quality of beater or beat-up mounting bracket and the quality of vehicle body all are improved on the mounting bracket of rear fender of N200 vehicle.Clamp and fulcrum post just are not easy wearing and tearing after Overheating Treatment, can not influence positioning accuracy.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
