Clamping mechanism of cylindrical workpieces

Abstract

The invention discloses a clamping mechanism of cylindrical workpieces. The clamping mechanism comprises a base, an upper clamping plate and a lower clamping plate. The lower clamping plate is fixed on the base. The upper clamping plate comprises a top pressure device, a left clamping plate and a right clamping plate, and the left clamping plate and the right clamping plate are provided with arc grooves respectively. The top pressure device comprises a left clamping jaw, a right clamping jaw, a sliding rod, a conical sliding block and a top pressure block. An arc groove is formed in the lower end of the top pressure block, a support is arranged on the base and connected with the sliding rod, and the lower end of the sliding rod penetrates through the conical sliding block to be vertically connected with the upper end of the top pressure block. The small-diameter end of the conical sliding block is close to the top pressure block, and the big-diameter end of the conical sliding block is far away from the top pressure block. A pull rod is arranged at the upper end of the conical sliding block, and the lower portion of the left clamping jaw butts against the outer wall of the left clamping plate. The lower portion of the right clamping jaw butts against the outer wall of the right clamping plate. The clamping mechanism of cylindrical workpieces overcomes defects of the existing expanding sleeve type clamping device of the cylindrical workpieces of incapability in clamping force control and poor applicability; can adjust the clamping strength according to the diameters of the workpieces, and is strong in applicability.

Description

technical field [0001] The invention belongs to the field of clamping devices, in particular to a clamping mechanism for cylindrical workpieces. Background technique [0002] Spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force and return to their original shape after removing the external force. They are generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] According to the nature of the force, the spring can be divided into tension spring, compression spring, torsion spring and bending spring, and can be divided into disc spring, ring spring, plate spring, coil spring, truncated cone scroll spring and torsion bar spring according to the shape. According to the production process, it can be divided into cold coil spring and hot coil spring. [...
