Multipurpose hydraulic vice and using method thereof

Abstract

The invention discloses a multipurpose hydraulic vise, which comprises a metal fixed clamp body, a movable clamp body assembly, a central plunger pump assembly, a pre-clamping screw and a clamping screw; the pre-clamping screw and the clamping screw pass through their own The rotation pushes the movable vise body assembly to move on the metal fixed vise body, and the workpiece is clamped by the central plunger pump assembly. The use method of the multi-purpose hydraulic vise described in the present invention, by rotating the pre-clamping screw rod, the movable clamp body moves forward; after the force becomes larger, the ratchet pin presses down the spring, the clamping screw rod continues to rotate, and pushes the center plunger pump column The plug generates high-pressure oil, thereby pushing the piston rods of the two clamps to move to realize the clamping of the workpiece; at the same time, the invention also has the advantages of reasonable design, simple and compact structure, long service life, wide application range, and low production, operation and maintenance costs. , easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a multi-purpose hydraulic vice and a method for using the same. Background technique [0002] The vise is a general-purpose fixture, which is often used to install small workpieces. It is a random accessory for milling machines and drilling machines. It is fixed on the machine tool table and used to clamp the workpiece for cutting. In mechanical processing, when drilling, milling, and processing parts in machining centers, flat-nose pliers are often used to clamp workpieces, but ordinary flat-nose pliers have high requirements for the parallelism of the clamped workpieces, and often can only clamp and fix relatively regular workpieces , but when the two surfaces of the workpiece are not parallel (that is, the so-called special-shaped parts), the clamping of the workpiece is not stable, which affects the machining accuracy, and even cannot be processed or cause safet...

In mechanical processing, when drilling, milling, and processing parts in machining centers, flat-nose pliers are often used to clamp workpieces, but ordinary flat-nose pliers have high requirements for the parallelism of the clamped workpieces, and often can only clamp and fix relatively regular workpieces , but when the two surfaces of the workpiece are not parallel (that is, the often-called special-shaped parts), the clamping of the workpiece is not stable, which affects the machining accuracy, and even cannot be processed or cause safety accidents

The Chinese patent, the application number is: CN204053832U, discloses a hydraulic vise; the patent injects hydraulic oil into the hollow rubber sleeve to expand the rubber sleeve to clamp the pipe, and adjusts the stroke of the hydraulic cylinder to drive the slider to clamp the common parts. The clamping is mainly achieved by the expansion of the rubber sleeve, resulting in a small clamping force, and can only clamp objects with smooth surfaces, and the application range is small

The Chinese patent, the application number is: CN203566522U, discloses a special hydraulic vise for the production of transmission towers; this patent is a special hydraulic vise for the production of transmission towers, the vise is fixed on the bracket connected, cannot move, and the structure is relatively complicated Not suitable for machine tool processing
