Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.

Referring to fig. 1 to 5, the clamping fixture of the present invention includes a bottom plate 1, a vertical plate 2, a fixing block 3 and a pressing member 4;

the vertical plate 2 is arranged on the bottom plate 1 and surrounds the bottom plate 1 to form a first space 100, the fixed block 3 is arranged on the vertical plate 2 and protrudes out of the vertical plate 2, the fixed block 3 is positioned in the first space 100, and the fixed block 3 is used for bearing external workpieces;

the pressing piece 4 is rotatably connected to the vertical plate 2 and is located in the first space 100, and the pressing piece 4 is used for pressing a workpiece on the fixing block 3.

Specifically, in this embodiment, bottom plate 1 and riser 2 are 90 degrees connections each other, install fixed block 3 at the mid-mounting of riser 2, the bottom and the 1 interval of bottom plate of fixed block 3 set up, fixed block 3 roughly is cylindricly, the quantity of briquetting 4 is two, the crossing setting of the center line of two briquetting 4 and fixed block 3, preferably, the center line coincidence of two briquetting 4 and the horizontal center line of fixed block 3, at first will wait to process the work piece and place on fixed block 3, accomplish the pre-fixing, finely tune after that, last rotatory briquetting 4, make briquetting 4 press and hold on the surface of work piece, make briquetting 4 compressed tightly to fix on fixed block 3.

Through installing fixed block 3 and casting die 4 on riser 2, casting die 4 rotates to be connected in riser 2, realizes improving the precision of work piece location to pre-fixing, finely tuning and final fixed of work piece.

The pressing piece 4 comprises a rotating sleeve 41 and a pressing part 42 connected with the rotating sleeve 41, the rotating sleeve 41 is rotatably connected with the fixed block 3, the pressing part 42 is close to or far away from the fixed block 3, and the rotating sleeve 41 and the pressing part 42 are connected in an approximately L shape, so that the pressing part 42 is far away from or close to the fixed block 3 through the rotation of the rotating sleeve 41, and the purpose of pressing or releasing the workpiece on the fixed block 3 is achieved.
