Embodiment Construction

[0040] Examples such as Figure 1-4 As shown, the link-type self-centering universal clamp includes a cylindrical clamp body 1 , one end of the clamp body 1 is fixedly connected with an upper end cover 11 , and the other end of the clamp body 1 is connected with a bottom plate 14 .

[0041] A central shaft 6 is slidably connected to the center of the clamp body 1 , and the axis of the central shaft 6 coincides with the axis of the clamp body 1 .

[0042] The central shaft 6 runs through the upper end cover 11 and the bottom plate 14, and the outer side of the central shaft 6 is covered with a guide sleeve 10, which is fixedly connected with the upper end cover 11. Fixed connection.

[0043] Three clamping slide shafts 2 are evenly arranged on the side wall of the clamp body 1 along its circumferential direction.

[0044] The clamping slide shafts 2 are arranged perpendicular to the axis of the central shaft 6, and the angle between two adjacent clamping slide shafts 2 is 120...

Abstract

The invention discloses a connecting rod type self-centering universal fixture. The connecting rod type self-centering universal fixture comprises a cylindrical fixture body in which a center shaft is connected in a sliding manner; a tight ejecting sliding shaft is connected to the side wall of the fixture body in a sliding manner and penetrates the side wall of the fixture body; and the center shaft is in transmission connection with the tight ejecting sliding shaft and moves to be capable of driving the tight ejecting sliding shaft to move so that a workpiece can be tightly ejected or released. The technical scheme adopted for the connecting rod type self-centering universal fixture has the following beneficial effects that the positioning precision of the fixture is improved by 1 / 2 compared with that of a universal chuck, and the precision reaches 0.03 mm; and the application range is wide, the diameter range of workpiecies to which the connecting rod type self-centering universal fixture is applicable can reach phi200-1200 mm, operation is easy, using is convenient, the production cost is reduced, and the trial effect is good.

Description

technical field [0001] The invention relates to a clamp used for self-centering and clamping of circular or annular workpieces such as tire molds, in particular to a link-type self-centering universal clamp. Background technique [0002] In the mechanical processing of workpieces such as tire molds, there are many rings, discs, and sleeves, such as bases, tread rings, etc., which need to be positioned and clamped on lathes, vertical and horizontal machining centers, and rotate coaxially with the worktable . [0003] At present, the alignment is performed manually through the measuring table. The alignment process is very cumbersome and time-consuming, causing the machine tool to stop and wait, which affects the operating rate of the machine tool and the processing efficiency of the workpiece. [0004] In order to solve this problem, we designed a self-centering clamping tool for disk workpieces. Contents of the invention [0005] The technical problem to be solved by the...
