Abstract

The invention relates to the technical field of clamping devices, in particular to a floating inner support positioning clamping device. The device comprises a base, a driving rod, a first expansion block, a second expansion block, a third expansion block, a linkage block, a steel ball and a connecting rod; the base is of a cavity structure, the driving rod is fixedly connected with the first expansion block, the outer wall of the first expansion block is in sliding connection with the inner wall of the base, the inner wall of the first expansion block is in sliding fit with the steel ball, the steel ball abuts against the second expansion block and the wedge face of the linkage block at the same time, the linkage block is fixedly connected to the lower end of the connecting rod, a cavityallowing the connecting rod to move downwards is formed in the first expansion block, the middle and the upper portion of the connecting rod are sleeved with the second expansion block and the third expansion block correspondingly, and the second expansion block and the third expansion block are in sliding fit with the connecting rod. The floating inner support positioning clamping device in the technical scheme has the beneficial effects of being good in fixing clamping effect and capable of effectively ensuring workpiece machining quality.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a positioning and clamping device for a floating inner support. Background technique [0002] During the machining process, it is necessary to locate and lock the parts to be processed. The positioning is used to ensure the accuracy of the machining, and the locking can prevent the parts from flying out during the machining process and prevent accidents. Existing fixtures are usually composed of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and clamping bodies. The loading and unloading of workpieces in use is troublesome, and for workpieces with high heights, the clamping The effect is not good, and the clamping of the workpiece from the outside or the inner wall may cause deformation of the workpiece and affect the quality of the workpiece. Contents of the invention [0003] The purpose of the present inv...
