Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] like Figure 1~Figure 4 As shown, the collet used for clamping the threading machine without damage includes a mounting plate 1, a jacket 2 and an inner sleeve 4, wherein the right end of the mounting plate 1 is coaxially equipped with a jacket 2, and the jacket 2 is placed and installed There are inner sleeves4.

[0023] Specifically, the mounting plate 1 has a through hole A5 along the axis, and its left end has an integral flange A6, and the flange A6 is distributed with a plurality of axial screw holes A7 along the disc, and the screw A8 passes through the screw. Fix the flange A6 on the end face of the main shaft of the threading machine after passing through the hole A7; the right end has an integrated flange B9, and the flange B9 has a plurality of axial bolt t...

Abstract

The invention relates to a chuck used for die head threading machine clamping without damages. The chuck comprises a mounting disc and a clamping sleeve mounted on the end part of the mounting disc, and further comprises an inner barrel for clamping a steel tube, wherein the mounting disc is provided with a coaxial through hole A; the clamping sleeve is cylindrical, and is provided with a coaxialthrough hole B; a notch is formed in the cylindrical wall of the right end of the clamping sleeve, and a clamping block is arranged in the notch; the clamping block and the clamping sleeve define a complete cylinder; a seam A is formed between the clamping sleeve and the clamping block, a spring is arranged between the clamping sleeve and the clamping block, and the clamping sleeve and the clamping block are connected through a bolt E; the inner barrel comprises an upper half barrel and a lower half barrel, and a seam B is formed between the upper half barrel and the lower half barrel; the upper half barrel is mounted on the clamping block through a bolt C; and the lower half barrel is mounted on the inner wall of the clamping sleeve through a bolt D. The chuck has the beneficial effects of not generating clamping damages on the steel tube, being capable of regulating circular run-out degree after once clamping, and guaranteeing clamping precision.

Description

technical field [0001] The invention relates to the field of chucks of threading machines, in particular to the chucks used for clamping non-damaged threading machines. Background technique [0002] Threading machine, also known as pipe threading machine. When working, first put the pipe to be threaded into the pipe chuck, impact and clamp it tightly, press the start switch, the pipe will rotate with the chuck, adjust the size of the die opening on the die head, and set the length of the thread opening. Then turn the feed handwheel clockwise to make the die cutter on the die head close to the end of the rotating pipe with constant force. When the mouth is processed to the preset length, the die cutter will be opened automatically, and the wire mouth processing is completed. Turn off the power, pop the chuck open, and remove the tube. [0003] Therefore, more or less pinch marks will be left on the surface of the steel pipe, which is unacceptable for some plastic-coated st...
