Embodiment Construction

[0013] The present invention will be described below with reference to the drawings.

[0014] As attached figure 1 , 2 , 3 shows a fixing fixture according to the present invention, including a sleeve 1 and a fixing pin 2; four springs 3 are fixed around the inner wall of the sleeve 1; the springs 3 are evenly arranged in the sleeve On the inner wall of 1, and the other end of each spring 3 is fixed with a clamping block 4; the cross section of the clamping block 4 is arc-shaped, and its clamping surface 7 in contact with the workpiece is wavy; the sleeve A fixing hole 5 is opened at the end of the fixing hole 5; a fixing pin 2 matched with the fixing hole 5 is provided in the fixing hole 5.

[0015] The above-mentioned springs can also be three, and there are also three corresponding clamping blocks.

[0016] When in use, the fixed pin 2 is removed, the workpiece 6 to be operated is screwed into the sleeve 2, and then the fixed pin 2 is inserted into the fixed hole 5 and penetrat...

Abstract

The invention discloses a fixture which comprises a sleeve and a fixing pin. Four springs are fixed on the inner periphery wall of the sleeve and are evenly arranged on the inner wall of the sleeve. A clamp block is fixed to the other end of each spring. The section of each clamp block is arced. A clamping surface of each clamp block, in contact with a workpiece, is corrugated. The tail end of the sleeve is provided with a fixing hole. The fixing pin matching with the sleeve is disposed in the fixing hole. A rotor is fixed with the clamp blocks and is further locked with the fixing pin, so that twisting is convenient and fast and installation is compact. In addition, the corrugated clamping surfaces enable friction to be increased and wearing of workpieces to be avoided. The fixture is simple in structure and convenient to operate and can be higher in efficiency and quality.

Description

Technical field [0001] The invention relates to a clamping device, in particular to a fixed clamp for clamping a workpiece, and belongs to the field of mechanical tooling. Background technique [0002] In industrial production, it is often necessary to perform threading, upper nut, upper pipe joint or other torsion operations on steel pipes or some cylindrical workpieces. However, this type of revolving body is more troublesome during the twisting operation, and the revolving body must be fixed. At present, the twisting operation is generally performed after manual fixation, that is, grasping the rotating body with one hand and twisting with the other hand. However, hands are often injured during operation, and some installed pipe joints and nuts will fall off due to incomplete installation, which not only wastes time and wastes manpower, but also affects production quality and efficiency. Summary of the invention [0003] In view of the above-mentioned technical problems, the p...
