Eccentric-wheel-type rapid clamping vice

Abstract

The invention discloses an eccentric-wheel-type rapid clamping vice. The eccentric-wheel-type rapid clamping vice comprises a fixed vice body installed on a base, wherein a movable vice body and an eccentric wheel device are installed on the fixed vice body. The eccentric-wheel-type rapid clamping vice further comprises a positioning circular column arranged on the upper plane of the base, wherein the positioning circular column is matched with a hole on the bottom of the fixed vice body, the bottom plane of the fixed vice body is connected against the upper plane of the base, and fixing bolts are arranged at the both sides of the fixed vice body; and horizontal convex-concave grooves are further arranged on the two side surfaces of the fixed vice body, the movable vice body is installed on the fixed vice body, and the convex-concave grooves of the movable vice body are inserted in the convex-concave grooves of the fixed vice body. The eccentric-wheel-type rapid clamping vice further comprises jaw plates arranged on the fixed vice body and the movable vice body. By virtue of the mode, the eccentric-wheel-type rapid clamping vice can be used for greatly shortening the time needed by clamping a workpiece in case of ensuring an enough clamping force to reliably clamp the workpiece, and is especially suitable for being used in occasion that blank dimensions are frequently changed; and moreover, the eccentric-wheel-type rapid clamping vice is simple and compact in structure, beautiful in shape, low in manufacturing cost, and convenient in replacement for worn components.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an eccentric wheel type fast clamping vise. Background technique [0002] The machine vise is fixed on the machine tool through the base. The fixed clamp body is assembled with the base through bolts. Loosening the bolts to fix the body of the clamp can rotate a certain angle relative to the base to meet the processing requirements. The cylinder below the square nut cooperates with the space on the body of the fixed pliers, so that the box nut is axially positioned relative to the body of the fixed pliers. The screw rod is rotatably assembled on the movable tong body through a square nut, and the nut fixes the screw rod on the movable jaw, so that the rotating screw rod can drive the movable tong body to move back and forth relative to the fixed tong body, thereby achieving the effect of clamping and loosening the workpiece. [0003] This kind of ordinary vise with scre...

Problems solved by technology

[0003] This kind of ordinary vise with screw and nut as transmission parts has high manufacturing cost and complicated installation and debugging because the screw is a slender rod and requires high precision.

Screw and nut transmission converts rotary motion into linear motion. The transmission efficiency is low, and it takes a long time to clamp the workpiece. It is even more inconvenient in the occasion of frequent replacement of different blank sizes.
