Adjustable precision steel forging vise

Abstract

The invention discloses an adjustable precision steel forging vise which comprises a fixed vise body, a movable vise body, a screw, a nut, a pressing plate and a hexagon socket countersunk screw. The fixed vise body and the movable vise body are both in a component welding structure and are both made by forging steel. The movable vise body is provided with a guide rod which is provided with an elongated groove provided with the screw. The nut matched with the screw is mounted on the fixed vise body, and the pressing plate is tightened by the hexagon socket countersunk screw to be mounted at the end of the nut. A pair of outer guide rails and a pair of inner guide rails are arranged on the left sides and the right sides of the guide rod and the fixed vise body respectively, and the two pairs of guide rails are in a left-right asymmetric guide structure. The adjustable precision steel forging vise has the advantages that gaps among the guide rails are adjustable, the vise bodies are large in laryngeal size, clamping range of jaws is large, guide precision is high, and the vise bodies are high in strength and light in weight; the quick-wear part nut is more convenient to replace and maintain; and even stress on two sides of a workpiece can be achieved when the vise clamps the workpiece, and accordingly self-strength of the guide rod is given to full play, clamping force of the vise is increased, and the like.

Description

technical field [0001] The invention relates to the technical field of fitter clamping tools, in particular to an adjustable precision forged steel vise. Background technique [0002] Adjustable precision forged steel vise is a clamping tool for fitters, mainly used for fixing workpieces during machining by fitters. [0003] The structure of existing adjustable precision forged steel vise and the deficiencies thereof are as follows: [0004] (1) The screw rod is arranged above the guide rod, and a channel steel for protecting the screw rod is arranged above the guide rod. Since the screw rod is arranged above the guide rod, the throat depth resources of the vise are occupied, which affects the size and stability of the workpiece clamped by the vise. In addition, the channel steel used for the protective screw rod is increased, which not only wastes materials, but also increases the cost of manual production and welding, and also weakens the depth of the throat of the vise....

AI Technical Summary

Problems solved by technology

Since the screw rod is set above the guide rod, it occupies the throat depth resources of the vise, which affects the size and stability of the workpiece clamped by the vise

In addition, the channel steel used for the protective screw rod is added, which not only wastes materials, but also increases the cost of manual production and welding, and also weakens the depth of the throat of the vise.

[0005] (2) The thread that is screwed with the screw to generate the clamping force is directly arranged on the fixed pliers body, that is, the nut and the fixed pliers body are designed in one piece, which will cause the disadvantage that the thread cannot be repaired and replaced after the thread is damaged. Damage will lead to the fatal flaw of scrapping the entire vise

[0008] (5) The spring is assembled on the head of the screw rod and at the front end of the movable pliers, which not only causes too much space for assembling the spring, inconvenient assembly, but also weakens the strength of the movable pliers
