A load-bearing tool that can be quickly unloaded

Abstract

The invention relates to the field of mechanical tooling, and particularly discloses a load-bearing tooling capable of being fast unloaded.. The load-bearing tooling comprises an upper wedge-shaped box and a lower wedge-shaped box, wherein the upper wedge-shaped box and the lower wedge-shaped box are mutually wedged to form an entire box; a limiting pin is arranged on the upper wedge-shaped box; a limiting groove is formed in the lower wedge-shaped box, and is used for limiting the limiting pin; a first swinging block, a second swinging block and a third swinging block are arranged on the outer side wall of the lower wedge-shaped box; an anti-slip bar is fixedly arranged on the outer side wall of the upper wedge-shaped box; a V-shaped groove structure is formed in the second swinging block, and is used for limiting the anti-slip bar; the first swinging block is used for limiting the second swinging block in a horizontal position; and the third swinging block is used for limiting the first swinging block in a horizontal position. The tooling disclosed by the invention has the advantages of being simple to make,, quick in implementation, small in constraint release acting force and the like.

Description

technical field [0001] The invention relates to the field of mechanical tooling, in particular to a load-bearing tooling that can be quickly unloaded. Background technique [0002] General load-bearing tooling is not equipped with an unloading device, and it needs to use other tools to lift the heavy object before it can be disengaged. [0003] Unloadable load-bearing tooling generally adopts a wedge-shaped structure, which does not slide when bearing loads, and unloads to make it slide. Unloadable load-bearing tooling is usually divided into self-locking tooling and self-sliding tooling. "Self-locking" (that is, the friction force is greater than the sliding force) load-bearing tooling is unloaded by applying a certain horizontal force to make it slide away, but generally requires a relatively large horizontal force to achieve. When the "self-slip" (that is, the friction force is less than the sliding force) load-bearing tooling is loaded, the screw, the card slot, etc. a...

AI Technical Summary

Problems solved by technology

[0005] 1. It is difficult to unload, and generally requires a large horizontal force to achieve unloading

[0006] 2. The structure is complicated. The structure generally adopts more than two wedge boxes, and the restraint adopts the form of connecting rods. The production and maintenance process is relatively complicated.

[0007] 3. The unloading process is complicated, and tools such as electric wrench and hammer are generally needed for unloading

[0008] 4. The labor intensity is high when unloading
