Description

Jaw vice

Technical Field

The utility model relates to a vice.

Background

The bench vice is also called vice or bench vice. A vise is a universal fixture used to clamp workpieces. The device is arranged on a workbench and used for clamping and stably processing workpieces, and is a necessary tool for a bench worker workshop. The turntable type clamp body can rotate, so that the workpiece can rotate to a proper working position. The structure of the clamp consists of a clamp body, a base, a guide nut, a lead screw, a clamp opening body and the like. The movable pliers body is in sliding fit with the guide rail of the fixed pliers body through the guide rail. The lead screw is arranged on the movable caliper body, can rotate but cannot axially move, and is matched with a lead screw nut arranged in the fixed caliper body. When the handle is shaken to rotate the screw rod, the movable vice body can be driven to move axially relative to the fixed vice body, and the clamping or loosening effect is realized. The spring is fixed on the screw rod by the aid of the retainer ring and the split pin, and the spring has the function of enabling the movable pliers body to timely withdraw when the screw rod is loosened. The fixed pliers body and the movable pliers body are respectively provided with a steel jaw and are fixed by screws. The working surface of the jaw is provided with crossed reticulate patterns, so that the workpiece is not easy to slide after being clamped. The jaw is hardened through heat treatment, and has better wear resistance. The fixed clamp body is arranged on the rotary seat and can rotate around the axis of the rotary seat, when the fixed clamp body rotates to a required direction, the clamping handle is pulled to enable the clamping screw to be screwed tightly, and the fixed clamp body can be fastened under the action of the clamping disc. The rotary seat is provided with three bolt holes for fixing with the clamp platform. However, in the existing bench vices on the market, the movable jaw and the fixed jaw are basically close to and far away from each other by adopting the screw nut to clamp or release the workpiece, so that the workpiece is very slow in idle running, and the working efficiency of a bench worker is greatly reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a vice which is provided with a slow clamping mechanism, wherein when a workpiece is not clamped, the fixed vice body and the movable vice body slide to realize quick idle stroke advancing or idle stroke retreating, and after the workpiece is clamped or when the workpiece is just started to be separated from the clamping, the workpiece is slowly clamped or slowly separated from the clamping by rotating a handle, and the arrangement of a frustum-shaped section of a connecting sleeve in the slow clamping mechanism and a taper sleeve of a round rod connecting seat can play a better role in guiding during slow clamping and ensure that the alignment of a movable jaw and a fixed jaw is more accurate.

In order to achieve the purpose, the technical scheme of the utility model is to design a vice, which comprises a vice base and a rotating seat, wherein the rotating seat is rotatably arranged with the base; the movable clamp bodies are arranged in a split manner and respectively comprise a first movable clamp body and a second movable clamp body, and a slow clamping mechanism is arranged in each of the first movable clamp body and the second movable clamp body; the first movable clamp body and the second movable clamp body are arranged in a sliding mode with the fixed clamp body.

The two movable clamp bodies are arranged and matched with the clamp bodies to install the pressure plates with different shapes, so that the shape of the jaw can be changed to clamp workpieces with different types and shapes, particularly special-shaped workpieces.

The further technical proposal is that the vice is cast by No. 45 steel, the surface of the handle is provided with a chromium plating decorative layer, and the surface of the vice is provided with an electrostatic spraying layer. The jaw formed by the fixed forceps body and the movable forceps body and the anvil surface on the fixed forceps body are subjected to high-frequency quenching treatment.

The utility model has the advantages and beneficial effects that: the slow clamping mechanism is arranged, when a workpiece is not clamped, the fixed clamp body and the movable clamp body slide to realize fast idle stroke advancing or idle stroke retreating, after the workpiece is clamped or when the workpiece is just started to be separated from the clamping, the workpiece is slowly clamped or slowly separated from the clamping condition through the rotating handle, and the frustum-shaped section of the connecting sleeve in the slow clamping mechanism and the taper sleeve of the round rod connecting seat can play a better role in guiding during slow clamping and ensure that the movable jaw and the fixed jaw are aligned more accurately.

The round steel is inserted into the cylinder, so that the metal plate processing of the cylinder is facilitated.

The rotation of the round rod can be realized by rotating the handle; because the rod diameter of the round rod which penetrates through the movable clamp body and penetrates through the round rod part of the movable clamp body is smaller than the rod diameter of the round rod parts at two sides of the penetrating part, the movable clamp body can be moved in the horizontal direction by directly holding the handle during idle stroke advancing and retreating, and when a workpiece is not clamped (idle stroke advancing here) or is separated from the clamped workpiece (idle stroke retreating here), the movable clamp body can be quickly pushed to be close to the fixed clamp body or quickly pulled to be far away from the fixed clamp body. The outer surface of one section of the connecting sleeve, which is close to the handle, is provided with an external thread, and the round rod connecting seat is provided with a threaded hole matched with the external thread, so that the situations that the workpiece is clamped slowly and separated from the workpiece just beginning can be realized. And the frustum form section of adapter sleeve and the setting of the taper sleeve of round bar connecting seat can play better direction when slowly pressing from both sides and guarantee that movable vice jaw, fixed vice jaw are adjusted well more accurately, because the rotation axis of frustum form section is the horizontally in the design, consequently because the level of round bar has been guaranteed in the cooperation setting of the adapter sleeve of frustum form section and the taper sleeve of round bar connecting seat, just also guaranteed movable vice jaw, fixed vice jaw and adjusted well more accurately.
