Pipe fitting clamping mechanism

Abstract

The invention relates to a pipe fitting clamping mechanism. A first pipe clamping block and a first pin shaft are installed at both ends of a first finger arm, a second pipe clamping block and a second pin shaft are installed at both ends of a second finger arm, both ends of the first pin shaft and the second pin shaft extend from sliding chutes and the corresponding end parts are connected by return springs, the first pin shaft and the second pin shaft slip on the sliding chutes, the first finger arm and the second finger arm are respectively hinged on a stand by a first fixing pin shaft and a second fixing pin shaft, the first fixing pin shaft is arranged between the first pipe clamping block and the first pin shaft, and the second fixing pin shaft is arranged between the second pipe clamping block and the second pin shaft. Corresponding idler wheels are arranged on the first pin shaft and the second pin shaft, a push block having two guide faces is installed at the front end of a push shaft of a push cylinder, and a space wide position and a space narrow position are formed on the two guide faces. After the pipe fitting clamping mechanism is adopted, a copper pipe bent by a numerical control pipe bending machine is automatically taken out, the degree of opening is large, and automatic production of the numerical control pipe bending machine is realized. The pipe fitting clamping mechanism is suitable for clamping the copper pipes with different pipe diameters.

Description

(1) Technical field [0001] The invention relates to a pipe clamping mechanism. (2) Background technology [0002] The production of heat exchangers requires a large number of U-shaped tubes. During the production process, it is necessary to take out the U-shaped tubes that have been bent by the CNC tube bender. In the past, workers took out the U-shaped tubes from the CNC tube bender. This is not only inefficient, unsafe, but also labor-intensive. (3) Contents of the invention [0003] In order to solve the above problems, the present invention provides a clamping mechanism for pipe fittings, which can automatically take out the copper pipe bent by the CNC pipe bender, realize the automatic production of the CNC pipe bender, run smoothly, and have high production efficiency. [0004] For this reason, the present invention adopts following scheme to achieve the above object: [0005] A pipe clamping mechanism, comprising a machine base, a push cylinder, a first finger arm...
