Description

Technical Field

[0001] The utility model relates to the technical field of clamping fixtures, in particular to a machining clamping fixture. Background Art

[0002] When processing mechanical parts, workers will use clamping jigs to clamp and fix the mechanical parts, and then process and polish the parts. Bench vises are commonly used clamping jigs for fitters. By rotating the screw, the movable jaws move toward the fixed jaws, thereby firmly clamping the objects placed between the jaws.

[0003] When an object is clamped by the jaws, the worker needs to hold the top of the object with one hand and rotate the screw with the other hand, so that the movable jaw pushes the object to the position of the fixed jaw to squeeze and clamp the object. When most of the object extends out of the jaws, the hand is directly above the jaws, so the jaws will not touch the hand. However, when the object extends out of the jaws by a small amount, such as 1 cm, when the worker picks up the object, in order to keep the position of the object unchanged, he will ignore the placement of the wrist. When the hand is placed between the two jaws, the hand will be scratched or squeezed as the movable jaw moves. Utility Model Content
