Technical Field

The invention relates to a clamping vice, in particular to a vice for clamping a special-shaped workpiece by using parallel arms.

Background

The vice is a universal fixture used for clamping workpieces, is arranged on a workbench and is used for stably clamping the workpieces to be processed and is a necessary tool for a vice workshop. The vice for machine is characterized in that: the design structure is concise and compact, the clamping force is strong, and the operation and the use are easy. The inner nut is generally made of a stronger metal material, so that the clamping force is kept larger. The tooling clamp is an indispensable part for machining, can accurately fix the machining position of parts, reduces the labor intensity of workers and improves the labor efficiency. At present, common clamps are single in use, and one clamp is used for fixing workpieces in one shape or one clamp is used for fixing workpieces in various specifications and shapes. For some special-shaped workpieces, special tool fixtures must be replaced to fix the workpieces, so that time is wasted and cost is increased.

In view of the above problems occurring when fixing the different-shaped workpieces, it is urgently needed to develop a vise capable of firmly fixing the special-shaped workpieces by using parallel arms.

Disclosure of Invention

In order to overcome the defects that the common clamp has single use and has certain limitation in the process of fixing the workpiece with the irregular shape, such as insufficient clamping degree and easy displacement of the workpiece with the irregular shape, the technical problem is as follows: the utility model provides a can realize the vice of dysmorphism work piece centre gripping with the use parallel arm that dysmorphism work piece is firmly fixed.

The technical scheme of the invention is as follows: the utility model provides an use parallel arm to realize vice of dysmorphism work piece centre gripping, including:

the two vice frames are respectively a first vice frame and a second vice frame;

the first vice frame is far away from the second vice frame;

the first mounting block is rotatably connected to the first vice frame;

the universal shaft sleeves are symmetrically and fixedly connected to two sides of the vice frame;

the anti-skid pad I is fixed on one side of the vice frame through a screw;

the bearing nut is rotatably connected to the first mounting block;

the second vice frame is positioned on one side of the first vice frame;

the mounting block II is rotatably connected to the vice frame II, and the bearing nut is rotatably connected into the mounting block II;

the two universal shaft sleeves are symmetrically and fixedly connected to two sides of the vice frame II;

the antiskid pad II is fixed on one side of the vice frame II through a screw, and the antiskid pad I is far away from the antiskid pad II;

the first screw rod is connected with the bearing nuts in the first mounting block and the second mounting block;

the handle is rotatably connected to one end part of the screw rod;

and the two guide rods are respectively and symmetrically movably connected with the first universal shaft sleeve and the second universal shaft sleeve.

In one embodiment, the method further comprises the following steps:

the L-shaped frame is fixedly connected to the vice frame II;

The screw rod II is in threaded connection with the L-shaped frame;

and the pressure pads are rotationally connected to the two end parts of the screw rod.

Has the advantages that: 1: the invention can accurately fix the processing position of the part, has simple and compact design structure and is easy to operate.

2: the angle of the anti-skid pads on the two sides can be changed through the universal shaft sleeve and the guide rod, so that the shape of the anti-skid pads is attached to a special-shaped workpiece.

3: according to the invention, the handle is shaken to drive the screw rod I and the bearing nut in the mounting block I to rotate in a threaded manner, so that workpieces of different types can be processed, and the processing cost is reduced.
