The clamping device and its clamping process for machining the inner and outer circles of projectile workpieces

Abstract

The invention discloses a clamping device for in-vehicle and outer-circle machining of elastic body workpieces, which comprises a first connecting assembly, a second connecting assembly, a third connecting assembly, a fixing assembly and an elastic body workpiece body, the first connecting assembly The assembly is located between the second connection assembly and the third connection assembly, the second connection assembly is located on one side of the third connection assembly, and the body of the elastic body processing part is located between the first connection assembly, the second connection assembly and the third connection assembly. In the area enclosed by the components, two first fixing bolts are provided on the upper surface of the first connecting component near the first connecting component, and a first fixing bolt is provided on the upper surface of the first connecting component near the middle. The rotating assembly, the present invention is applicable to various working conditions, and can play a good role in fixing the inner and outer turning circles of the body of the projectile body, increasing the processing reliability of the workpiece, reducing the vibration marks in the inner cavity of the workpiece, and reducing the rotation of the workpiece. Stable workpiece size ensures product quality.

Description

technical field [0001] The invention relates to the technical field of projectile workpiece processing, in particular to a clamping device and a clamping process for machining the inner and outer circles of projectile workpieces. Background technique [0002] When the inner and outer circles of the projectile workpiece are rough-turned, lathes are often used to process them, but the projectile workpiece needs to be clamped and fixed before processing. Poor, the processing reliability of the workpiece is reduced, the vibration pattern in the inner cavity of the workpiece is increased, the workpiece is spinning, the size of the workpiece cannot be processed stably, the quality of the product cannot be guaranteed, and once the clamping fixture is damaged, the entire fixture needs to be replaced. The damaged parts cannot be replaced separately, which increases the wear and tear of the machine and the maintenance expenses. Contents of the invention [0003] In order to overcom...

[0002] When the inner and outer circles of the projectile workpiece are rough-turned, lathes are often used to process them, but the projectile workpiece needs to be clamped and fixed before processing. Poor, the processing reliability of the workpiece is reduced, the vibration pattern in the inner cavity of the workpiece is increased, the workpiece is spinning, the size of the workpiece cannot be processed stably, the quality of the product cannot be guaranteed, and once the clamping fixture is damaged, the entire fixture needs to be replaced. It is impossible to replace the damaged parts individually, which increases the loss of the machine and the maintenance cost
