Abstract
The utility model relates to a metal processing clamp, in particular to a spring clip in processing. The utility model solves the technical problems that the defects of the background art are overcome. An improved spring clip is provided, and has the characteristics of accurate positioning, reliable clipping and high processing quality. The utility model adopts the technical scheme that a split-type clip comprises a base, a pull rod positioned in a base shaft hole, and a clip formed by a plurality of clipping blocks and circled around the pull rod. The utility model is characterized in that apositioning plate is also positioned in the outer diameter direction of the clip, a certain distance exists between the outer circumferential surface and the positioning plate, the positioning surfaceof the positioning plate is higher than the end surface of each clipping block, and the positioning plate is fixed on the end surface of the base.
Description
Technical field
The utility model relates to a kind of metalworking anchor clamps, especially adds the collet in man-hour.
Background technology
Adopt clamping device mostly to be collet in the existing Vehicle Processing.This collet (shown in Figure 2) is to surround a whole circle by several fixture blocks 2 at circumferencial direction, and the axis position is provided with a pull-rod 4; The end face 2-2 position of collet is as the location, and outer circumference surface 2-1 (several fixture blocks on the chuck are arranged and formed) is as clamping the position.During work, the first clamping upper spring of part to be processed 5 (dotting among Fig. 2) chuck, the centre bore of part is set on the clamping position of collet; The pull-rod 4 that then is positioned at the axis position is moved to the left, and it is mobile that the outer circumference surface 4-1 of pull-rod expands these fixture blocks with regard to the fixture block that pushes the chuck left end to the outer diameter, thereby the centre bore of roof pressure part is fixed on the collet part.The shortcoming of this kind structure is: its localization part and clamping part connect together; So just a problem appears: because there is tolerance in the aperture of part, under the constant situation of clamping force and aperture hour, the end face localization part of chuck will form center indent phenomenon (gap B shown in Figure 4), and central protuberance phenomenon (clearance D shown in Figure 3) will appear in the end face localization part of chuck when the aperture is big; The part thickness that processes like this tends to the out-of-size scope.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of collet is provided, and this collet should have accurate positioning, clamping is reliable, crudy is high characteristics.
The technical scheme that the utility model provides is: split type collet, comprise pedestal, be arranged in the pedestal axis hole pull-rod, be looped around the chuck of forming by several fixture blocks around the pull-rod; The external diameter direction that it is characterized in that described chuck is also located a location-plate, between the outer circumference surface of fixture block and the location-plate certain spacing is arranged, and the locating surface of this location-plate is higher than the end face of described fixture block.
Described location-plate is fixed on the end face of pedestal.
Operation principle of the present utility model is: will locate with clamping to separate and carry out; The location clamps the outer circumference surface that then leans on several fixture blocks by the end face of location-plate; Because location-plate is fixed on the end face of pedestal, the locating surface of location-plate is higher than the end face of described fixture block again, so location-plate can not move and can keep benchmark constant; Pull-rod between the outer circumference surface of fixture block and the location-plate certain spacing arranged, so can not be subjected to the influence of location-plate when promoting fixture block clamping part.
The beneficial effects of the utility model are: clamping part and localization part separately after, no matter how the pore size of part changes all and can not be affected; Not only can keep accurate positioning, crudy is significantly improved, and clamping is reliable more, convenient.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of existing collet.
Fig. 3 is the schematic diagram of one of A portion state among Fig. 2.
Fig. 4 is two a schematic diagram of A portion state among Fig. 2.
The specific embodiment
As shown in the figure, split type collet, comprise pedestal 3, be arranged in the pedestal axis hole pull-rod 4, be looped around the chuck of forming by several fixture blocks 2 around the pull-rod; These structures are all identical with existing collet.
The utility model is also located a location-plate 1 in the external diameter direction of described several fixture blocks, between the outer circumference surface of fixture block 2 and the location-plate certain spacing is arranged, and can not run into location-plate when making the fixture block motion.This location-plate end face 1-2 is higher than the end face of described fixture block as locating surface, makes the location of part not be subjected to the influence of fixture block fully.
Described location-plate directly is fixed on the end face of pedestal, and the benchmark of location-plate can be remained unchanged.
Claims (2)
1, split type collet, comprise pedestal (3), be arranged in the pedestal axis hole pull-rod (4), be looped around the chuck of forming by several fixture blocks (2) around the pull-rod; The external diameter direction that it is characterized in that described chuck is also located a location-plate (1), between the outer circumference surface of fixture block (2) and the location-plate certain spacing is arranged, and the locating surface of this location-plate is higher than the end face of described fixture block.
2, split type collet according to claim 1 is characterized in that described location-plate is fixed on the end face of pedestal.
