Abstract

The utility mode discloses a clamping tool used for mushroom-shaped parts. The clamping tool comprises a hollow locating sleeve and is characterized in that an elastic fixture is installed inside the locating sleeve in a sliding mode, the rear end of the elastic fixture is connected with a pull rod, a plurality of axial grooves are formed at the front end of the elastic fixture, and the front end of the locating sleeve and the front end of the elastic fixture are provided with conical surfaces which are matched with each other, wherein the front portions of the conical surfaces are high, and the rear portions of the conical surfaces are low. A clamping sleeve is further installed inside the elastic fixture in a sliding mode, and the clamping sleeve is also provided with a plurality of axial grooves. The clamping tool has the advantages of being high in clamping efficiency, stable in clamping, and good in safety.

Description

A kind of clamping tooling for bacterium shape part
Technical field
The utility model relates to a kind of clamping tooling for bacterium shape part.
Background technology
Be the product of bacterium shape for profile, need holding workpiece bar section when its endoporus of processing, as shown in Figure 1, generally adopt at present three-jaw self-centering chuck 7 clamping workpieces 6, the rotating number of turns of chuck handle is more during clamping, and clamping efficient is low; When turning processing work endoporus, iron filings are strip and are difficult for discharging, and affect product processing quality, and long iron filings easily are wrapped on the scroll chuck 7, jeopardize operator's safety.
The utility model content
The purpose of this utility model is for the prior art above shortcomings, and a kind of clamping tooling for bacterium shape part is provided, and it has the advantage that clamping efficient is high, security is good.
For achieving the above object, clamping tooling for bacterium shape part of the present utility model, the positioning sleeve that comprises hollow, it is characterized in that the spring chuck that is provided with that in positioning sleeve, slides, the rear end of spring chuck connects with a pull bar, and the front end of spring chuck is provided with several axial grooves, the front end of positioning sleeve and the front end of spring chuck be provided with match and front height after the low conical surface, that also slides in spring chuck is provided with mounting clip sleeve, and mounting clip sleeve also is provided with several axial grooves.
During use, positioning sleeve is fixed on the machine tool chief axis, pull bar connects with parts such as oil cylinders, workpiece bar section is loaded in the mounting clip sleeve, by pulling back pull bar, pull bar drives spring chuck and endwisely slips in positioning sleeve, the conical surface compressing spring chuck of positioning sleeve front end, the front end of spring chuck clamps mounting clip sleeve and workpiece successively in axial shrinkage; When using the utility model clamping workpiece, only need the pulling pull bar to get final product, the distortion of spring chuck and mounting clip sleeve is little, and clamping is firm, has the advantage easy to operate, that efficient is high; Because it is less that spring chuck and mounting clip sleeve expose size, iron filings are difficult for twining on it, and security is good;
As further improvement of the utility model, also be provided with annular groove at the front end cylindrical of mounting clip sleeve; Be convenient to take out mounting clip sleeve;
In sum, the utlity model has the advantage that clamping efficient is high, clamping is firm, security is good.
Description of drawings
Fig. 1 is the use state diagram of existing clamping tooling.
Fig. 2 is front view of the present utility model.
Fig. 3 is the front view of mounting clip sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Such as Fig. 2, shown in Figure 3, the clamping tooling that should be used for bacterium shape part, the positioning sleeve 1 that comprises hollow, be provided with spring chuck 2 in positioning sleeve 1 interior slip, the rear end of spring chuck 2 and a pull bar 3 pass through thread connection, the front end of spring chuck 2 is provided with four axial groove 2a, the front end of the front end of positioning sleeve 1 and spring chuck 2 be provided with match and front height after the low conical surface, that also slides in spring chuck 2 is provided with mounting clip sleeve 4, mounting clip sleeve 4 also is provided with four axial groove 4a, also is provided with annular groove 4b at the front end cylindrical of mounting clip sleeve 4.
During use, positioning sleeve 1 is fixed on the machine tool chief axis, pull bar 3 connects with parts such as oil cylinders, the bar section of workpiece 5 is loaded in the mounting clip sleeve 4, by pulling back pull bar 3, pull bar 3 drives spring chuck 2 and endwisely slips in positioning sleeve 1, the conical surface compressing spring chuck 2 of positioning sleeve 1 front end, the front end of spring chuck 2 clamps mounting clip sleeve 4 and workpiece 5 successively in axial shrinkage; When using the utility model clamping workpiece, only need pulling pull bar 3 to get final product, the distortion of spring chuck 2 and mounting clip sleeve 4 is little, and clamping is firm, has the advantage easy to operate, that efficient is high; Because it is less that spring chuck 2 and mounting clip sleeve 4 expose size, iron filings are difficult for twining on it, and security is good.

Claims (2)

1. clamping tooling that is used for bacterium shape part, the positioning sleeve that comprises hollow, it is characterized in that the spring chuck that is provided with that in positioning sleeve, slides, the rear end of spring chuck connects with a pull bar, the front end of spring chuck is provided with several axial grooves, the front end of positioning sleeve and the front end of spring chuck be provided with match and front height after the low conical surface, that also slides in spring chuck is provided with mounting clip sleeve, mounting clip sleeve also is provided with several axial grooves.
