Abstract

The utility model relates to a thread protection type special jig which comprises a lifting rod and cross frames. The three cross frames are fixedly arranged on the lifting rod, a plurality of elastic sheets are fixedly arranged on the two sides of each cross frame back to back, the elastic sheets are composed of elastic sheet bottom plates, elastic sheet side plates and elastic sheet blunt tip teeth, the elastic sheet bottom plates are fixed to the cross frames, the elastic sheet side plates are arranged on two sides of the elastic sheet bottom plates, the elastic sheet side plates and the elastic sheet bottom plates are in an open horn shape, the elastic sheet blunt tip teeth are arranged on the outer sides of the elastic sheet side plates, V-shaped blunt tip teeth are formed in the elastic sheet blunt tip teeth, reinforcing iron blocks used for keeping the elasticity of the elastic sheets are further arranged on the elastic sheet bottom plates, the elasticity of the elastic sheets is kept, the service life of the elastic sheets can be prolonged, and the usage rate of the elastic sheets can be increased. According to the thread protection type special jig, internal threads of a product can be protected against damage in the locating process, the elastic sheet blunt tip teeth in the elastic sheets can be supported in the internal threads, and the product can be firmly fixed by the elastic sheets through the elasticity of the elastic sheets.

Description

A kind of thread protection special fixture

Technical field

The utility model relates to a kind of tool fixture, relates in particular to a kind of thread protection special fixture.

Background technology

Producing in there is the product that thread need to process its outer surface some inside, always a little bother in the work that it is fixed, is clamped, the conventional tool that interiors of products is supported, easily causes damage in various degree to thread, and easily generation is slided, is offset.

Summary of the invention

Easily thread is caused to damage in various degree when solving above-mentioned fixed product, and easily produce the problems such as slip, skew, the utility model provides a kind of thread protection special fixture.

The technical scheme in the invention for solving the technical problem is: a kind of thread protection special fixture, comprise lifting arm, crossbearer, on described lifting arm, be fixed with three crossbearers, on the both sides of described each crossbearer, be fixed with back-to-back a plurality of shell fragments, described shell fragment is by shell fragment base plate, shell fragment side plate and shell fragment rush canine tooth composition, described shell fragment base plate is fixed on crossbearer, described shell fragment side plate is located at the both sides of elastic bottom plate and to be open type horn-like with elastic bottom plate, described shell fragment rushes canine tooth and is located at the outside of shell fragment side plate, described shell fragment rushes and on canine tooth, offers V-arrangement and rush canine tooth, on described elastic bottom plate, be also provided with to keep the flexible reinforcing iron block of shell fragment, keep the elasticity of shell fragment can increase its service life and utilization rate.

Further, on described each crossbearer, be fixed with three pairs of shell fragments, can hang the product of fixing greater number, enhance productivity.

Further, to rush canine tooth be that punching press, bending are one-body molded, convenient for production, elasticity meets the demands for described shell fragment base plate, shell fragment side plate and shell fragment.

The beneficial effects of the utility model: the internal screw thread that the utility model can be protected product is not damaged in the time of location, and the shell fragment in shell fragment rushes canine tooth and can be supported in internal screw thread, the elasticity of shell fragment has ensured that it can firmly must fix product.

Brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

A kind of thread protection special fixture as shown in the figure, comprise lifting arm 1, crossbearer 2, on described lifting arm 1, be fixed with three crossbearers 2, on the both sides of described each crossbearer 2, be fixed with back-to-back a plurality of shell fragments 3, described shell fragment 3 is by shell fragment base plate 31, shell fragment side plate 32 and shell fragment rush canine tooth 33 and form, described shell fragment base plate 31 is fixed on crossbearer 2, described shell fragment side plate 32 is located at the both sides of elastic bottom plate 31 and to be open type horn-like with elastic bottom plate 31, described shell fragment rushes canine tooth 33 and is located at the outside of shell fragment side plate 32, described shell fragment rushes and on canine tooth 33, offers V-arrangement and rush canine tooth, on described elastic bottom plate 31, be also provided with to keep the flexible reinforcing iron block 4 of shell fragment 3, keep the elasticity of shell fragment can increase its service life and utilization rate.

Further, on described each crossbearer 2, be fixed with three pairs of shell fragments 3, can hang the product of fixing greater number, enhance productivity.

Further, described shell fragment base plate 31, shell fragment side plate 32 and shell fragment rush canine tooth 33 for punching press, bending are one-body molded, convenient for production, elasticity meets the demands.

It is emphasized that, it is more than preferred embodiment of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
