Abstract

The invention discloses a clamp for numerical control machining. The clamp comprises a support and an inner hole positioning and expansion mechanism. The inner hole positioning and expansion mechanismcomprises an installing plate, an expansion assembly and a locking assembly. The expansion assembly comprises an expansion sleeve, a spindle and a locking nut. The locking assembly comprises a locking plate, locking sleeves screws and a positioning plate. The installing plate is connected with the support. A plurality of first positioning holes are circumferentially and evenly distributed in theinstalling plate. A plurality of through holes are circumferentially and evenly distributed in the positioning plate. Each through hole is aligned and connected with the corresponding locking sleeve.A plurality of second positioning holes are circumferentially and evenly distributed in the locking plate. The first positioning holes, the through holes and the second positioning holes are the samein number and corresponding in position. The clamp is ingenious in structural design, convenient to use and reliable in clamping.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a fixture for numerical control machining. Background technique [0002] When existing workpieces are numerically controlled, welded, drilled, etc., it is often necessary to position and clamp the inner hole of the workpiece to facilitate the rapid processing of the workpiece. However, there is no positioning and clamping device for the inner hole that can meet the requirements. further research and development. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a clamp for numerical control machining with ingenious structural design, convenient use and reliable clamping. [0004] In order to achieve the above object, the present invention provides a fixture for numerical control machining, including a bracket and an inner hole positioning expansion mechanism, the inner hole position...
