Novel clamp for machining thin-wall cylinder part

Abstract

The invention discloses a novel clamp for machining a thin-wall cylinder part. The novel clamp comprises a mandrel, a positioning plate, connecting pipes, spacer bushes, expansion components and a pressing plate. The positioning plate is fixed to one end of the mandrel. The connecting pipes are fixed to the mandrel and tightly attached to the positioning plate. The spacer bushes, the expansion components and the pressing plate are installed on the connecting pipes. The novel clamp for machining the thin-wall cylinder part is easy to manufacture, operation is convenient, multiple supporting points exist on the clamp, the area is large, the good expansion performance is achieved, the part can be prevented from deforming and vibrating in the machining process, the machining precision of the part is effectively ensured, and the use requirement of the part is effectively met.

Description

technical field [0001] The invention relates to a fixture, in particular to a novel fixture for processing thin-walled cylindrical parts, and belongs to the technical field of mechanical processing. Background technique [0002] With the rapid development of modern machining, machining technology has also developed rapidly. In mechanical processing, as a device for fixing the processing object, the application of fixtures is very important. Slender and thin-walled cylindrical parts are widely used in actual production and are relatively difficult to process. Whether the positioning and clamping of such parts is reasonable in machining determines the deformation of the part and directly affects the machining accuracy of the part. Such slender and thin-walled cylindrical parts are long in length, thin in wall thickness, and poor in rigidity. During turning, they are easily affected by factors such as clamping, gravity, vibration, and thermal deformation caused by cutting. It ...

Problems solved by technology

Such slender and thin-walled cylindrical parts are long in length, thin in wall thickness, and poor in rigidity. During turning, they are easily affected by factors such as clamping, gravity, vibration, and thermal deformation caused by cutting. It is difficult to ensure the machining accuracy and accuracy of the workpiece. Requirements

[0003] At present, the conventional fixtures used for processing slender and thin-walled cylindrical parts have many shortcomings, mainly as follows: 1) The positioning reference and design reference are not uniform, and it is difficult to ensure the verticality of the end face and the axis; 2) The workpiece clamping is time-consuming and laborious, which affects production Efficiency; 3) The workpiece is prone to deformation and vibration during the cutting process, which affects the machining accuracy and use requirements of the workpiece; 4) The surface of the workpiece is prone to scratches during the machining process
