Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

As shown in fig. 1, the quick positioning fixture for a joint of the present invention comprises a joint 1, wherein a first fixing plate 2 and a second fixing plate 5 are arranged on an end surface of the joint 1; be provided with first mounting hole on the first fixed plate 2, be provided with the second mounting hole on the second fixed plate 5, the plug-in nut subassembly that is equipped with in the first mounting hole, the one end of nut subassembly stretches out the second mounting hole and fixes through mounting 7, and mounting 7 supports presses in the outside of second fixed plate 5.

When the quick positioning clamp for the joint is used, the nut assembly is firstly disassembled, then a part is installed between the first fixing plate 2 and the second fixing plate 5, then the nut assembly penetrates through the clamp body and the part, and then the nut assembly is fixed through the fixing piece 7, so that the part is positioned.

The nut component and the position where the part penetrates through play a role in positioning, and after the machine tool can clamp the joint 1, the next step of finish machining can be performed on the part.

Referring to fig. 2, in the quick positioning fixture for a connector of the present invention, the nut assembly includes a first step 3, a second step 4 and a threaded connection portion 6, which are connected in sequence, the first step 3 is pressed against the outer side of the first fixing plate 2, the second step 4 is located between the first fixing plate 2 and the second fixing plate 5, the threaded connection portion 6 extends out of the second mounting hole, and the fixing member 7 is mounted on the threaded connection portion 6.
