Abstract

The utility model belongs to a connecting rod auxiliary jig used for processing of the internal thread of a copper pipe. The jig comprises a bracket and a T-shaped screw rod, wherein a transversal cut is processed on the main body of the bracket, a bolt hole penetrating to the transversal cut is processed at the top of the bracket, the T-shaped screw rod is screwed in the bolt hole, and a locating groove is arranged at a position on the transversal cut and corresponding to the T-shaped screw rod. The jig of the utility model has the advantages of simple structure, durability and labor conservation.

Description

The auxiliary clamp of the connecting rod that a kind of copper pipe internal thread machining is used

Technical field:

The utility model belongs to the auxiliary clamp of the connecting rod that a kind of copper pipe internal thread machining uses.

Background technology:

All needing to draw copper pipe before the copper pipe machining internal thread advances in the thread generator, this distraction step need be used draw bar, connecting rod and vice, one end of connecting rod is connected with copper pipe to be processed, the other end needs in the auxiliary precession draw bar screw of vice, in this precession process, vice all is to come the turn connecting rod by the power that human arm is bestowed, and has so not only required great effort but also damages vice easily, now lacks a kind of durable, auxiliary jockey in labour-saving.

Summary of the invention:

The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, and a kind of auxiliary clamp of durable, connecting rod that labour-saving copper pipe internal thread machining is used is provided.

For achieving the above object, the technical scheme that the utility model provides is: the auxiliary clamp of the connecting rod that a kind of copper pipe internal thread machining is used, these anchor clamps include support and T shape screw rod, on rack body, be processed with cross sections, prop up top of the trellis and be processed with the screw that extends through cross sections, T shape screw rod is threaded onto in the screw, has detent on position corresponding with T shape screw rod on the cross sections.

Anchor clamps of the present utility model have simple in structure, durable and the labour-saving advantage.

Description of drawings:

Fig. 1 is the three-dimensional structure diagram of the utility model anchor clamps;

Fig. 2 is the structural representation of the holder part of the utility model anchor clamps;

Fig. 3 is the structural representation of the utility model clamp clamps connecting rod.

The specific embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

Shown in accompanying drawing 1～accompanying drawing 3, the auxiliary clamp of this connecting rod includes support 1 and T shape screw rod 2, on support 1 body, be processed with cross sections 3, be processed with the screw 5 that extends through cross sections 3 at support 1 top, T shape screw rod 2 is threaded onto in the screw 5, on position corresponding on the cross sections 3, have detent 4 with T shape screw rod 2, when clamping connecting rod 7 bodies of rod of end connection copper pipe 6 are positioned in the detent 4, turn T shape screw rod 2 is up to compressing connecting rod 7, rotate whole anchor clamps, make in the connecting rod 7 threaded end precession draw bars 8, take away the step that anchor clamps carry out next step traction machining internal thread at last.

Claims

1. the auxiliary clamp of the connecting rod used of a copper pipe internal thread machining, these anchor clamps include support (1) and T shape screw rod (2), it is characterized in that: on support (1) body, be processed with cross sections (3), and be processed with the screw (5) that extends through cross sections (3) at the top of support (1), T shape screw rod (2) is threaded onto in the screw (5), goes up on the position corresponding with T shape screw rod (2) at cross sections (3) and has detent (4).
