Special fixture for numerical control machining center

Abstract

The invention discloses a special fixture for a numerical control machining center. The special fixture comprises a fixing plate, wherein a clamping assembly is arranged at the bottom of the fixing plate; the clamping assembly comprises two clamping plates vertically and oppositely arranged; one end of each clamping plate is slidably connected with the fixing plate through a guide structure; the two clamping plates can move towards each other along the guide structures; a plurality of clamping parts are uniformly distributed on the opposite sides of the two clamping plates, wherein each clamping part comprises a fixing seat, and the fixing seats are fixed to the clamping plates; one surfaces, away from the clamping plates, of the fixing seats are connected with contact parts; a multi-stagebuffer structure is arranged between each contact part and the corresponding fixing seat; the bottom of the fixing plate is further provided with a plurality of telescopic devices; and the telescopicends of the telescopic devices are connected with one sides, opposite to each other, of the two clamping plates. The special fixture is simple in structure and convenient to operate, can clamp workpieces of different shapes on the premise of ensuring stable clamping, avoids clamping damage on the surfaces of the workpieces, and is worth popularizing.

Description

technical field [0001] The invention relates to the field of mechanical fixtures, in particular to a special fixture for a numerically controlled machining center. Background technique [0002] Numerical control machining (numerical control machining) refers to a process method for processing parts on a numerical control machine tool. The process regulations of numerical control machine tool machining and traditional machine tool machining are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the movement of parts and tools. It is an effective way to solve the problems of variable variety, small batch, complex shape and high precision of parts and realize high-efficiency and automatic processing. CNC machining refers to the processing that the control system issues instructions to make the tool perform various movements that meet the requirements, and express the technical requirements and proces...
