Abstract
The utility model provides a collet for a tensioning clamp, which is applied to the technical field of tensioning clamps of universal joints. The collet (1) in a hollow cylindrical structure comprises a collet rear end (2) and a collet front end (3), and more than four slots (4) are arranged at the collet front end (3) which is in a taper structure with the diameter gradually increasing towards the position of a front end face (11). The collet is capable of enhancing universality and interchangeability and rotating freely so as to adjust clearance of the collet and the axial diameter of a steering joint and guarantee the inner diameter D1 to be abraded uniformly. Simultaneously, the collet applied to the tensioning clamp of the universal joint has fine elasticity, abrasion resistance and fatigue strength.
Description
Technical field
The utility model relates to universal joint stretching device technical field, in particular, relates to a kind of collet that is applied to the universal joint stretching device.
Background technique
The taper angle of existing collet tapering surface is bigger, easy to wear, is not suitable for the frequent use of chuck, and the chuck structure cylindrical that do not lead now moves instability behind the chuck in addition, also causes wearing and tearing easily.
The model utility content
Technical problem to be solved in the utility model is: a kind of collet that is applied to the universal joint stretching device with favorable elasticity, wear resistance and fatigue strength is provided.
Solve above-described technical problem, the technological scheme that the utility model is taked is:
The utility model is a kind of collet that is applied to the universal joint stretching device, described collet is set to the tubular structure of hollow, collet comprises chuck rear end and chuck front end, the fluting more than four is offered in the position of described chuck front end, and described chuck front end is set to the diameter cone structure that increases gradually of endface position forward.
The cone structure of described collet is set to be set to by the tapering between chuck body and the tapering surface 1: 8 structure.
The fluting of described collet is set to be evenly arranged in the structure on the chuck front end, and described each fluting all is set to be with front-end face the structure of angle, and described angle is set to the structure between 45 degree-90 degree.
The chuck rear end of described collet sets out external thread structure, and described external thread structure is connected with piston rod.
The preferred material of described collet is spring steel 65Mn or tool steel T8A.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Collet of the present utility model can strengthen the versatility and the interchangeability of collet; Chuck can freely rotate, thereby can be by rotation, adjusts the gap of chuck and the universal joint diameter of axle, and assurance inside diameter D 1 can uniform wear; Simultaneously, collet of the present utility model has the collet that is applied to the universal joint stretching device of favorable elasticity, wear resistance and fatigue strength.

Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment:
As accompanying drawing 1---shown in the accompanying drawing 3, the utility model is the collet that is applied to the universal joint stretching device, described collet 1 is set to the tubular structure of hollow, collet 1 comprises chuck rear end 2 and chuck front end 3, the fluting 4 more than four is offered in the position of described chuck front end 3, and described chuck front end 3 is set to the diameter cone structure 5 that increases gradually of end face 11 positions forward.
The cone structure 5 of described collet 1 is set to be set to structure between 1: 8 by the tapering between chuck body 6 and the tapering surface 7.
The fluting 4 of described collet 1 is set to be evenly arranged in the structure on the chuck front end 3, and described each fluting 4 all is set to be with front-end face 11 structure of angle, and described angle is set to the structure between 45 degree-90 degree.
The chuck rear end 2 of described collet 1 sets out external thread structure 12, and described external thread structure 12 is connected with piston rod 13.
The preferred material of described collet 1 is spring steel 65Mn or tool steel T8A.
In collet 1 of the present utility model, change its tapering into 1: 8 structure, thereby reduce the surface friction drag between tapering surface 7 and the sliding sleeve 14; In the utility model, chuck rear end 2 is processed external thread structure 12, thereby external thread structure 12 is connected with piston rod 13, be used for conductive liquid pressure; Diameter of axle D10 cooperates with hollow piston 16, thereby collet 1 is played support and leading role.
In addition, structure of the present utility model can also be passed through rotation collet 1, thereby the gap between the diameter of axle D10 of adjustment collet 1 and knuckle 15 guarantees inside diameter D
18 can uniform wear, thereby the uneven wear amount of the collet that makes 1 is not more than 0.25mm.
With 65Mn is example, with its technological process that is processed as collet 1 is: blanking-rough turn-heat treatment (modified)-half essence-threading-groove milling-spot welding-heat treatment (quenching)-grinding-removal soldering point.Wherein spot welding is that fluting is afterwards coupled together the end of four shell fragments of formation, reduces the heat treatment deformation and the grinding vibrations of postorder.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
