Positioning expanding core clamp

Abstract

The invention provides a positioning expansion core clamp. The positioning expansion core clamp is composed of a pull rod, a chuck fixing seat, a flange plate, an expansion core fixing sleeve, an expansion core, a taper core, a pull rod nut, a fixing seat and a buckle positioning seat, wherein the chuck fixing seat and the flange plate are sequentially laminated in the axial direction, the upper end of the expansion core is provided with an elastic expansion end, the lower end of the expansion core is provided with a fixed end, the middle end of the expansion core is provided with a fixed connecting disc, the fixed connecting disc is fixedly connected with a through hole through bolts, the pull rod axially penetrates through the expansion core and is spirally connected with the pull rod nut, the taper core is positioned between the expansion core and the pull rod nut, the expansion core fixing sleeve sleeves on the outer ring of the expansion core and is symmetrically and fixedly connected with the flange plate through bolts, the fixing seat and the buckling positioning seat are fixedly connected with the two ends of the expansion core through bolts respectively. According to the positioning expansion core clamp, the fixing seat, the buckle positioning seat and the expanding core clamp are combined, so that the same force is obtained in each clamping process, the repeated positioning precision is high, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a tool with a clamping function for machine tool processing, in particular to a positioning expansion core clamp. Background technique [0002] When processing some small workpieces such as gears, it is often necessary to repeatedly clamp the workpiece or perform the same clamping action on several identical workpieces. It is required that the fixture can quickly output the same clamping force each time. In the prior art , in order to keep the fast and precise clamping force of the fixture, it needs to be manually adjusted repeatedly, thereby reducing the production efficiency, and the operation is complicated, which increases the labor cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to output the same clamping force stably and accurately when the clamp repeatedly clamps the workpiece or performs the same clamping action on several identical workpieces. In order to solv...
