Embodiment Construction

[0010] Such as figure 1 As shown, the special fixture for special-shaped workpieces includes, from left to right, an annular transition plate 1, an annular faceplate 2 connected with the transition plate 1, and a clamping device connected with the faceplate; the clamping device includes a sleeve at the left end The support sleeve 3 in the faceplate, the screw 4 that runs through the support sleeve, the pressure plate 5 that is sleeved on the screw 4, and the washer 7 and the nut 6 that are sleeved on the right end in turn; The compression step part 8.

[0011] When in use, because the screw is installed in the support sleeve, and the support sleeve is installed in the faceplate, the screw is fixed on the faceplate indirectly; and because the pressure plate set on the screw is provided with a compression step, the entire step surface of the workpiece is in line with the pressure plate. The tight step contact not only prevents the workpiece from moving axially, but also prevent...

Abstract

The invention relates to the technical field of machine tool clamps, in particular to a special clamp of irregular workpieces. The special clamp comprises a transition plate, a face plate connected with the transition plate, and a clamping device connected with the face plate. The clamping device comprises a supporting sleeve with the left end sleeved in the face plate, a screw penetrating through the supporting sleeve, a pressing plate sleeved on the screw, and a nut and a gasket which are used for fastening the pressing plate. A pressing step portion fit with the step surfaces of workpieces is arranged at the left end of the pressing plate. The special clamp facilitates processing of annular parts with steps.

Description

technical field [0001] The invention relates to the technical field of machine tool fixtures, in particular to special-shaped fixtures for workpieces. Background technique [0002] When processing ring parts with steps, it is very cumbersome to use ordinary chucks or combined fixtures in the process of alignment, clamping and centering, especially when there are many such workpieces, the workload is very huge ,Time-consuming. Contents of the invention [0003] The purpose of the present invention is to provide a special-shaped workpiece fixture which is convenient for processing the annular parts with steps. [0004] Technical scheme of the present invention is as follows: [0005] The special fixture for special-shaped workpieces includes, from left to right, a transition plate, a face plate connected with the transition plate, and a clamping device connected with the face plate; Screws, a pressing plate sleeved on the screws, and nuts and washers for fastening the pre...
