Problems solved by technology

[0002] The existing fixture is used in the processing of the generator pulley of the automobile engine, the processing of seamless steel pipe, and the processing of seamless pipe, because it is necessary to process the outer circle and inner circle of the workpiece, but because the clamping force of the fixture is constant, the workpiece will be within the processing. When it is round, deformation occurs due to excessive clamping force, which affects the machining accuracy and makes it difficult for the inner hole size of the workpiece to meet customer requirements.

Abstract

The invention discloses an anti-deformation machining device and method for an automobile generator pulley. A rotary connector is connected with an oil cylinder which is connected with a chuck through a multi-stage connecting part. A claw is mounted on a claw base which is provided with an arc-shaped wedge block, and the chuck is clamped on the arc-shaped wedge block to be connected with the claw base. A locating block is arranged on the chuck in the claw base. An air pipe penetrates into the rotary connector, the oil cylinder, the connecting part and the chuck. When the oil cylinder drives the chuck to move backwards through the multi-stage connecting part, the arc-shaped wedge block is clamped by the chuck, the claw base is driven to move backwards to enable the claw to contract so as to clamp a workpiece, and the workpiece is driven to move backwards until the workpiece abuts against the locating block. When the oil cylinder drives the chuck to move forwards through the multi-stage connecting part, the chuck drives the claw base and the locating block to move forwards so as to enable the claw to loosen the workpiece. By means of the machining device and method, stress deformation of the workpiece can be prevented, precision is high, and requirements of clients are met.

Description

Technical field: [0001] The invention belongs to the field of seamless steel pipe processing, in particular to an anti-deformation processing device and processing method for an automobile generator pulley. Background technique: [0002] The existing fixture is used in the processing of the generator pulley of the automobile engine, the processing of the seamless steel pipe, and the processing of the seamless pipe, because it is necessary to process the outer circle and the inner circle of the workpiece, but because the clamping force of the fixture is constant, the workpiece will be within the processing. When it is round, deformation occurs due to excessive clamping force, which affects the machining accuracy and makes it difficult for the inner hole size of the workpiece to meet customer requirements. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be ta...
