Abstract
The invention discloses a clamping device, and particularly relates to a clamper clamping an internal part of a workpiece. The clamper clamping the internal part of the workpiece comprises a base seat and a positioning device arranged on the base seat, the positioning device comprises a clamping piece and a fixing piece, wherein the clamping piece is of a barrel-shaped structure, and the lower portion of the fixing piece is in threaded connection with the base seat. A cross through groove is arranged in the clamping piece. Compared with the prior art, the clamper clamping the internal part of the workpiece solves the problem that discarded clampers are inconvenient to replace in the prior art, and adopts a spilt structure design. The clamper clamping the internal part of the workpiece can be replaced conveniently due to the fact that the clamper body is in threaded connection with the base body, and at the same time different clamping pieces can be adopted according to different structures of the clamping pieces. Due to the fact that the clamping piece adopts the barrel-shaped structure and the cross through groove is arranged in the clamping piece, the clamper clamping the internal part of the workpiece achieves clamping of the workpiece by sleeving the clamping piece into the workpiece.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to the fixture of a kind of clamping work pieces inside.
Background technology
Clamping device is widely used for manufacturing.As to punching press, riveted joint, the welding of workpiece, paste or solidify etc. and usually need the position relationship that keeps correct in process.Clamping device has various reference surfaces or point, and workpiece can accurately be located, so clamping device is considered to requisite parts in processing industry.
In industrial circle, we are when processing work outside, often need clamping is carried out in the inside of workpiece, thereby process, adopt fixture integrated for existing fixture more, such fixture, although stability is high, but in the prolonged and repeated use of fixture, wearing and tearing are inevitably, so just need irregular replacing holder.
Summary of the invention
The object of the present invention is to provide the fixture of a kind of clamping work pieces inside, solve in existing field and change the drawback of scrapping the fixture trouble, can according to the different structure of holder, can adopt different holders simultaneously.
The present invention is achieved by the following technical solutions:
The fixture of a kind of clamping work pieces inside comprises pedestal and is located at positioner on pedestal that described positioner comprises the holder of top drum type structure and the fixture that the bottom is connected with base thread, has cross recess on described holder.
The invention has the beneficial effects as follows:
Compared with prior art, the invention solves in existing field and change the drawback of scrapping the fixture trouble, adopt the split-type structural design, pedestal and chuck body are threaded connection, the replacing fixture is convenient, for the different structure of holder, can adopt different holders simultaneously; The top holder adopts the drum type structural design, the lateral wall arc transition, and its middle part diameter is maximum, offers cross recess on holder, and holder is divided into four clamping faces, also makes four clamping faces have certain shrinkage simultaneously.The inside diameter of workpiece is slightly less than the maximum gauge of holder, in holder was inserted in workpiece, four clamping faces were simultaneously stressed because of the extruding of workpiece, and this moment, four clamping faces shrank to the center of holder, also workpiece is produced an opposition simultaneously, thus clamping work pieces.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of holder in Fig. 1 of the present invention.
The specific embodiment
By reference to the accompanying drawings shown in 1,2, the fixture of a kind of clamping work pieces inside, comprise pedestal 1 and be located at positioner on pedestal 1, described positioner comprises the holder 2 of top drum type structure and the fixture 3 that the bottom is threaded with pedestal 1, has cross recess 4 on described holder 2.Wherein, described holder 2 is used for clamping work pieces 5.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (1)
1. the fixture of a clamping work pieces inside, comprise pedestal and be located at positioner on pedestal, it is characterized in that: described positioner comprises the holder of top drum type structure and the fixture that the bottom is connected with base thread, has cross recess on described holder.
