Drawings

In order that the present disclosure may be more readily and clearly understood, reference is now made to the following detailed description of the embodiments of the present disclosure taken in conjunction with the accompanying drawings, in which

FIG. 1 is a schematic structural view of the present invention;

the specification reference numbers indicate: 1. the device comprises a base, 2, a support column, 3, a positioning block, 4, a propping mechanism, 41, a transmission block, 42, a transverse cylinder, 43, an accommodating groove, 44, a propping block, 45, a nylon block, 46 and an elastic piece.

Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to FIG. 1: the utility model provides a fixture for work piece, includes base 1, is equipped with a plurality of support columns 2 and a pair of corresponding locating piece 3 that is located the adjacent side of support column 2 and mutually perpendicular on base 1, specifically, the quantity of support column 2 is four and is the rectangle and distributes, and support column 2 plays as follows: the support device is used for supporting the workpiece, and the problem that the workpiece is deformed due to insufficient rigidity and lack of support of the workpiece in the machining process is avoided. The base 1 is further horizontally connected with a pair of elastic abutting mechanisms 4 which are opposite to the positioning blocks 3, can be far away from or close to the supporting columns 2 and have elasticity, and the positioning blocks 3 and the abutting mechanisms 4 jointly enclose the supporting columns 2. Through the structure, under the matching of the pair of positioning blocks 3 and the abutting mechanism 4, the clamp realizes the technical effect of effectively fixing the workpiece without damage.

Further, support tight mechanism 4 and include that the level is located the top of base 1 and the transmission block 41 relative with locating piece 3, transmission block 41 is connected with horizontal cylinder 42 with deviating from of locating piece 3 on the face, horizontal cylinder 42 is installed on base 1, set up horizontal holding tank 43 that link up on the opposite face of transmission block 41 and locating piece 3, holding tank 43 is the U type, vertical rotation is connected with and supports tight piece 44 in the holding tank 43, it is equipped with nylon block 45 of outstanding holding tank 43 on the opposite face of tight piece 44 and locating piece 3 to support, it is connected with a plurality of evenly distributed's elastic component 46 with holding tank 43 to deviate from the face, specifically, elastic component 46 is the spring. Through setting up like this, not only make the jointly effectively reduced fastening force that horizontal cylinder 42 exported to the work piece at nylon block 45 and spring, connect under the cooperation of the piece 44 that supports of holding tank 43 at spring and vertical rotation moreover for nylon block 45 can closely support the work piece when the fastening.

Further, the driving block 41 and the receiving groove 43 are integrally formed, so that the structure is compact and the strength is high.
