Problems solved by technology

[0002] The three-jaw chuck is one of the fixtures commonly used on machine tools. In frequent and high-strength use, the jaws are affected by factors such as mechanical fatigue, pressure deformation, and wear deformation. The back is trumpet-shaped, and cannot firmly clamp the workpiece. When the tool exerts force, the workpiece will swing laterally; the second is that the jaws are not concentric, and the workpiece will run out radially, making it difficult to align the workpiece.
Both of these problems will lead to reduced work efficiency and workpiece quality, and increased scrap rate
The traditional correction method is to clamp a spacer at the rear of the three jaws, and then correct the position of the spacer at the rear of the jaws. The operation is troublesome and affects the service life of the jaws.
Chinese Patent Publication No. CN201049426Y disclosed on April 23, 2008 "a tool for repairing the positive jaws of a three-jaw chuck". Set them on the three claws respectively, and finally put the ring on the three claws, and correct the claws after clamping, which is more cumbersome to use

Embodiment Construction

[0015] The specific implementation, structure, features and functions of a claw corrector proposed according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0016] see Figure 1-5 , The claw corrector is a ring 1, and one side of the ring 1 is evenly provided with three bumps 2, and a bell mouth 3 of 120° is formed between adjacent bumps 2.

[0017] When in use, pass the three claws of the three-jaw chuck through the three bell mouths 3 formed between the adjacent bumps 2, so that the working surface of the claws is exposed in the ring 1, adjust the claws to turn the chuck The claw corrector is clamped on the 120° inclined surface of the claw, and the working surface is corrected with a round knife. It only takes a few minutes to correct and recover.

[0018] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any simple modi...

Abstract

The invention discloses a clamping jaw corrector which is applied to the correction of a three-jaw chuck of a machine tool. The clamping jaw corrector is characterized in that the clamping jaw corrector is a ring (1); three bumps (2) are uniformly arranged on one surface of the ring (1); and two adjacent bumps (2) have a horn-shaped opening (3) of 120 degrees. The clamping jaw corrector has the advantages of good correcting effect, simple structure and convenient use.

Description

technical field [0001] The invention relates to the technical field of clamp correction, in particular to a jaw corrector. Background technique [0002] The three-jaw chuck is one of the fixtures commonly used on machine tools. In frequent and high-strength use, the jaws are affected by factors such as mechanical fatigue, pressure deformation, and wear deformation. The back is trumpet-shaped and cannot firmly clamp the workpiece. When the tool exerts force, the workpiece will swing laterally; the second is that the jaws are not concentric, the workpiece will run out radially, and it is difficult to align the workpiece. These two problems will lead to the reduction of work efficiency and workpiece quality, and the increase of scrap rate. The traditional correction method is to hold a gasket at the rear of the three claws, and then correct the position of the gasket at the rear of the claws. The operation is troublesome and affects the service life of the claws. Chinese Pate...
