Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of processing of annular thin-walled parts, in particular to a clamping device for annular thin-walled parts. Background Technique
[0002] An annular part refers to a component in a circular ring shape. The annular part can be made of metal materials, plastic materials, etc. The annular part can be further classified into thick annular parts, ordinary annular parts, and annular thin-walled parts according to the thickness of its wall. An annular thin-walled part refers to a circular ring-shaped component with a relatively small wall thickness, lower than the normal processing requirements. Due to its thin wall, the annular thin-walled part is prone to bending, deformation, or even direct fracture due to material brittleness when subjected to excessive force. Therefore, great care is needed during positioning.
[0003] The publication number (CN220093791U) discloses a clamping device for annular thin-walled parts. Select an inner arc-shaped piece that matches the size of the to-be-processed annular part, fix the inner arc-shaped piece at the end of the fixed plate, start the driving motor, and stop the driving motor when the diameters of the four inner arc-shaped pieces are the same as the inner wall diameter of the to-be-processed annular part. Insert a spliced arc-shaped piece that matches the inner wall radian of the to-be-processed annular part into the gap between the inner arc-shaped pieces. Then, set the to-be-processed annular part outside the tight circular ring formed by the inner arc-shaped piece and the spliced arc-shaped piece that matches the to-be-processed annular part. At this time, the support from the inside of the to-be-processed annular part is completed. When clamping the annular thin-walled part, the above device also needs to select and install a matching inner arc-shaped piece and a spliced arc-shaped piece, which will lead to relatively low clamping efficiency of the annular thin-walled part and needs to be improved.
