Abstract
The invention discloses a clamp for a steel pipe and belongs to the field of machining equipment. The clamp comprises a base, a connecting part and a clamping part and is provided with a concentric hole which penetrates through the base, the connecting block and the clamping part and is used as an operating channel of the steel pipe; the part of the concentric hole, which is positioned at the clamping part, is provided with a shrinking part; and the clamping part is provided with at least more than two grooves for penetrating through the whole clamping part. The clamp disclosed by the invention has the advantages that the structure is simple, the clamping is convenient, the manufacture is convenient, the cost is low, the steel pipe can be effectively clamped, and no deviation of the central line of the steel pipe is ensured.
Description
Technical field
The present invention relates to the process equipment field, especially for the fixture of holding workpiece.
Background technology
The fixture of steel pipe is very strange, and useful large clip is directly clamped, and also useful hydraulic cylinder withstands, and offers in addition arcuate die and clamps, and type is various.Emphasis is all to clamp steel pipe, but can not injure steel pipe, and will clamp conveniently.
Summary of the invention
Purpose of the present invention, be to solve the problems of the technologies described above, and a kind of fixture of automatic clamping steel pipe is provided.
Technical solution of the present invention is: a kind of fixture for steel pipe comprises base, contiguous block and clamping part, and has offered the concentric holes as steel pipe operation passage through base, contiguous block and clamping part; Described concentric holes is positioned at the part setting of clamping part and dwindles section, described clamping part offer at least 2 roads above for running through the groove of whole clamping part.
Steel pipe is through concentric holes, and because dwindling the effect of section, so at first steel pipe can run into a resistance, then steel pipe, under the effect of thrust, can move on, so can give active force of clamping part.Because clamping part has been offered groove, active force can make clamping part expansion, causes steel pipe to pass, but the section that dwindles can continue to chucking power of steel pipe, if thrust disappears, steel pipe will be fixed, and can not rotate and axially-movable.
As preferably, described dwindling in section offered frictional groove.Frictional groove can increase the chucking power of the section of dwindling to steel pipe.
As preferably, described dwindling in section arranges rubber blanket.Rubber blanket is in order to prevent the scratch of the section that dwindles to steel pipe.
As preferably, also offer groove on described contiguous block, described groove and groove are a whole piece groove.
As preferably, the medial surface that described base is positioned at concentric holes arranges enlarging section.
As preferably, the edge of described enlarging section is arc transition.
As preferably, the diameter of described base is greater than the diameter of contiguous block, and the diameter of base is less than the diameter of clamping part.
Beneficial effect of the present invention is: this clamp structure is simple, and clamping is convenient.Whole fixture is easy to make, and cost is low, and can effectively clamp steel pipe, guarantees that the center line of steel pipe can not be offset.
The accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural perspective;
The profile that Fig. 2 is embodiment of the present invention structure.
In figure: the 1-base, the 2-contiguous block, the 21-groove, the 3-clamping part, the 31-groove, the 32-frictional groove, 33-dwindles section, 4-concentric holes, 41-enlarging section.
The specific embodiment
Below in conjunction with accompanying drawing, with embodiment, the invention will be further described.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this specification, but as long as all are subject to the protection of Patent Law in claim scope of the present invention.
