Embodiment Construction

[0032] see Figure 1 to Figure 3 , shows one embodiment of the clamping system for fine machining of large workpieces of the present invention.

[0033] In this embodiment, the clamping system for fine machining of large workpieces includes a clamping disc 20 that can move along the workpiece table 10, and the clamping disc 20 is provided with a plurality of dovetails radiating outward from the center of the disc. Clamping slots 21, each dovetail clamping slot 21 is provided with rotating clamping blocks 22 that can be slid and fixed along the dovetail clamping slots, so that workpieces of various shapes can be clamped by sliding and fixing a plurality of rotating clamping blocks 22, optional Yes, the plurality of dovetail clamping grooves 21 are eight dovetail clamping grooves arranged at equiangular intervals. Through such an arrangement, it is possible to stably clamp various large-scale workpieces with special shapes or plastic shapes. Among them, the eight dovetail clampi...

Abstract

Provided are a clamping system and method for finish machining of large workpieces. The clamping system comprises a clamping disk which is provided with a plurality of dovetail clamping grooves radiated to the outside from the center of the disk; a rotating clamping block capable of performing sliding and fixing along the corresponding dovetail clamping groove is arranged in each dovetail clampinggroove, and therefore due to sliding and fixing of the plurality of rotating clamping blocks, the large workpieces in various shapes are clamped; each rotating clamping block is driven through a micro motor, each micro motor is connected to the bottom of the corresponding rotating clamping block through a ball screw structure, and therefore sliding and fixing of the rotating clamping blocks in the dovetail clamping grooves are achieved, and each rotating clamping block is provided with a force sensor; and thus, the clamping system and method for finish machining of the large workpieces can guarantee workpiece clamping during finish machining, and guarantee the excellent rate of the workpieces after machining.

Description

technical field [0001] The invention relates to the technical field of fine processing, in particular to a clamping system and method for fine processing of large workpieces. Background technique [0002] In modern machinery manufacturing, in addition to cutting, the methods of workpiece processing include casting, forging, welding, stamping, extrusion, etc., but when processing workpieces with higher precision requirements and finer surface roughness requirements, Traditional processing concepts can no longer meet people's requirements for processing speed, efficiency and precision, and usually need to be processed on CNC machine tools that perform fine processing. [0003] As the country's fine processing requirements for large workpieces are getting higher and higher, in order to improve the processing efficiency and processing accuracy of such complex products, craftsmen have been seeking more efficient and precise processing methods. [0004] For this reason, the desig...
