Clamp device for machining long-cylinder thin-wall part

Abstract

The invention discloses a clamp device for machining a long-cylinder thin-wall part. The clamp device is composed of end caps, pull rods and a pressing nut. The end caps comprise the left end cap and the right end cap. The pull rods are threaded-face pull rods and comprise the left pull rod and the right pull rod. The left pull rod is connected with the left end cap, and the right pull rod is connected with the right end cap. The pressing nut is installed on the right end cap. The clamp device for machining the long-cylinder thin-wall part is low in manufacturing cost and convenient and reliable to operate, the machining precision and the machining safety of the long-cylinder thin-wall part can be ensured, and the qualification rate and the machining effect of the part can also be improved.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture device for processing long-tube thin-walled 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. Long-tube thin-walled parts are widely used in actual production and are 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. Due to the long length and thin wall thickness of the long tube and thin-walled parts, it is difficult to clamp the parts during the machining process, the parts are easily deformed, and the radial dimensional accuracy is difficult to guarantee. [0003] At present, the tra...

Problems solved by technology

The disadvantages of this type of fixture are: 1) In order to ensure the safety and reliability of the processing, the plug and the parts need an interference fit, and the installation of the plug must apply external force. After the parts are processed, the removal of the plug is very difficult and time-consuming to operate. 2) The outer circle of the plug is ground one-to-one according to the hole size of the part to meet a certain amount of interference and ensure the safety of the part processing. Therefore, a set of plugs can only be used once, resulting in extreme clamping. Big waste; 3) After completing the turning and grinding of the outer circle of the part and applying external force to remove the interference fit plug, the radial deformation of the part is very large, and the accuracy of the outer circle and inner hole cannot be guaranteed
