Abstract

This utility model discloses the Simple clamp of a kind of turning bent sub, including can clamping at the stub material (1) of three-jaw self-centering chuck, one end of described stub material (1) is inclined-plane, and the angle on described inclined-plane is 90 ° of α, and described inclined-plane is machined with through hole (3)；Described processing bent sub component device also includes nut (2).This utility model clamping workpiece is reliable, is particularly suited for single-piece repair or small serial production, it is not necessary to makes complicated fixture and just can go into operation rapidly, has simple in construction, the easily manufactured and feature of good economy performance.

Description

A kind of Simple clamp of turning bent sub

Technical field

This utility model relates to a kind of fixture, the Simple clamp of a kind of turning bent sub.

Background technology

In tow-armed robot body construction and key feature production process, production can run into processing various forms and The bent sub of angle, the position of its processing includes the turning of two ends internal and external threads, brill, car two ends endoporus and makes it accurately connect Logical, owing to the blank shape of bent sub mostly is the shape less casting of rule, forging, this brings the most tired to the installation of workpiece Difficult.

By domestic and foreign literature and patent retrieval, and this utility model does not has similarity.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the letter of a kind of simple in construction turning bent sub Easily fixture.

This utility model solves this technical problem and be the technical scheme is that the Simple clamp of a kind of turning bent sub includes Can clamping at the stub material of three-jaw self-centering chuck, one end of described stub material is inclined-plane, and the angle on described inclined-plane is 90 °-α, described α are the angle between trunnion axis and bending axis, and described inclined-plane is machined with through hole.

For improving the reliability of clamping, further, the Simple clamp of described turning bent sub also includes nut.

For simplifying structure, further, described through hole is taper hole.

After using technique scheme, it is not necessary to making complicated fixture and just can go into operation rapidly, clamping workpiece is reliable, the suitableeest For single-piece repair or small serial production.This utility model has simple in construction, the easily manufactured and feature of good economy performance.

Accompanying drawing explanation

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

Accompanying drawing is respectively numbered: 1. stub material；2. nut；3. through hole；4. bent sub part；5. bending axis；6. trunnion axis.

Detailed description of the invention

In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine accompanying drawing, This utility model is described in further detail.

Refering to Fig. 1, the Simple clamp of a kind of turning bent sub include can clamping at the stub material 1 of three-jaw self-centering chuck, One end of described stub material 1 is inclined-plane, and the angle on described inclined-plane is 90 ° of-α, and described α is trunnion axis 5 and bending axis Angle between 6, described inclined-plane is machined with through hole 3.

For improving the reliability of clamping, further, described processing bent sub component device also includes nut 2.

For simplifying structure, further, described through hole 3 is taper hole.

Operation principle of the present utility model is as follows: use a stub material 1 to be whittled into an inclined-plane at one end mill so that it is folder Angle is equal to 90 ° of-α, holes after line on inclined-plane, and pore size adapts with the cylindrical of bent sub part 4, finally The exit milling in hole is put down.The one end processed by bent sub part 4 during use is inserted in Folder through-holes 3, Tightened with nut 2, then can will be added on the other end clamping of stub material 1 to lathe three-claw self-centering chuck Work.

Particular embodiments described above, solves the technical problem that this utility model, technical scheme and beneficial effect are carried out Further describe, be it should be understood that and the foregoing is only specific embodiment of the utility model, not For limiting this utility model, all within spirit of the present utility model and principle, any amendment of being made, equivalent, Improve, within should be included in protection domain of the present utility model.
