Automatic clamping mechanism for precision CNC lathes based on bar machining

Abstract

This utility model discloses an automatic clamping mechanism for a precision CNC lathe based on bar machining, including a mounting shell and a clamping mechanism. The mounting shell has sliding grooves on both its front and rear sides. The clamping mechanism includes clamping blocks, second limiting grooves, limiting rings, and a drive assembly. The clamping blocks are slidably connected to the inside of the sliding grooves. Each clamping block has an anti-slip protrusion on the side near the center of the mounting shell. Each second limiting groove is located in the middle of the inside of the clamping block. Each of the four vertically adjacent second limiting grooves is slidably connected to a limiting ring. Each second limiting groove is inclined outward with the side near the limiting ring as its center. The drive assembly is located between the limiting ring and the middle of the inside of the mounting shell. This automatic clamping mechanism for a precision CNC lathe based on bar machining, with its clamping mechanism, can automatically and accurately clamp workpieces and has a self-locking effect. It can also simultaneously clamp the front and rear sides of the outer surface of the bar, improving the concentricity of the bar.
