Abstract

The invention relates to a processing clamping device for a thin-walled framework. The device comprises a main coil clamping tube mounted inside a main coil framework, wherein a plurality of positioning block components distributed along the peripheral direction are arranged on the outer peripheral surface of the main coil clamping tube; the positioning block components comprise outer side positioning blocks and inner side positioning blocks which are symmetrically arranged; the outer side positioning blocks and the inner side positioning blocks are separately connected with the main coil framework through main coil clamping bolts; and the outer side positioning blocks and the inner side positioning blocks are separately fixedly connected with the main coil clamping tube through positioning block mounting bolts. The device has the advantages that the device can not only avoid clamping damage to high precision outer periphery caused by direct clamping of the outer peripheral surface ofthe thin-walled framework, but also realize the fact that processing of two ends of the thin-walled framework is accomplished at one step after the thin-walled framework is clamped, avoids concentricity error at the two ends caused by turning processing of a workpiece, and thoroughly solves twist deformation to the workpiece by the rolling torque of a machine tool.

Description

technical field

[0001] The invention relates to the clamping of a thin-walled frame on a horizontal processing lathe, in particular to a processing and clamping device and a clamping method of a thin-walled frame, belonging to the technical field of mechanical processing. Background technique

[0002] The clamping of the existing thin-walled frame on the horizontal processing lathe is usually to weld multiple supports inside the frame to increase the rigidity of the frame and reduce the deformation of the frame. When the existing clamping method is processed, it has the following disadvantages

[0003] One is that the outer circle of the frame needs to be clamped from one end. When processing the outer circle of the other end, the frame needs to be turned around to re-clamp the outer circle that has been processed, and then process the outer circle of the unprocessed end again. The main coil frame cannot be processed at one time. low precision;

[0004] The second is that ...
