Description

A quick vise

the

technical field

The invention relates to a vise, in particular to a fast vise.

Background technique

In the field of machinery and other industries, the widely used clamping tools and those sold on the market are traditional vise with a guide nut structure that has not changed for many years. This type of vise mainly includes a base, an operating handle, The base is connected with a fixed clamp body, the fixed clamp body is connected with the opening and closing of the movable clamp body through a screw, the operating handle is connected with a handle seat, and the movable clamp body is driven to move forward and backward by turning the screw rod through the handle to realize the clamping of the workpiece And relax, the speed of adjusting the gap between the jaws is slow, the operator is labor-intensive, and the efficiency is low.

Contents of the invention

The object of the present invention is to provide a quick vise with fast opening and closing jaws and high working efficiency.

In order to achieve the above object, the technical solution adopted in the present invention is: a quick vise, comprising a base and an operating handle, the base is connected with a fixed clamp body, the fixed clamp body is connected with a movable clamp body through a screw, and the operating handle is connected with a The handle seat is characterized in that: the left part of the lead screw is designed with a right-handed thread, the right part of the lead screw is designed with a left-handed thread, the thread on the lead screw in the movable clamp body is screwed with a left-handed nut, and the left-handed nut is connected to the movable clamp through the sliding key. Body level sliding connection, the right end of the left-handed nut is fixedly connected with a boss, the boss is located outside the movable clamp body, the left end of the left-handed nut is designed with a retaining ring groove, and a C-shaped elastic retaining ring is installed in the retaining ring groove, and the C-shaped elastic stop The right side of the ring is provided with a gasket, and the left-handed nut on the right side of the gasket is covered with a threaded spring. The left-handed nut corresponds to the left-handed thread.

The advantages and effects of the present invention are: due to the structure of the present invention, the jaws of the present invention can be quickly opened and closed to improve work efficiency.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

The present invention is shown in Figure 1, a kind of fast vise, comprises base 13, operating handle 9, and base 13 is connected with fixed clamp body 1, and fixed clamp body 1 is connected with movable clamp body 2 by lead screw, and on the operating handle Connected with a handle base, it is characterized in that: the left part of the leading screw is designed with a right-handed thread 14, the right part of the leading screw is designed with a left-handed thread 12, and the thread on the leading screw in the movable clamp body 2 is screwed with a left-handed nut 11, left-handed. The nut 11 is slidingly connected with the horizontal plane of the movable clamp body 2 through the sliding key 6, the right end of the left-handed nut 11 is fixedly connected with the boss 7, and the boss 7 is located outside the movable clamp body 2, and the left end of the left-handed nut 11 is designed with a retaining ring groove 4 , the retaining ring groove 4 is equipped with a C-shaped circlip 3, the right side of the C-shaped circlip 3 has a gasket, the left-handed nut 11 on the right side of the gasket is covered with a threaded spring 5, the left-handed nut 11 and the left-handed thread 12 Correspondingly, the right end of the leading screw has a square joint 10, and the square joint 10 is fixedly connected with the handle base through the pin 8.

Using the present invention, when the operating handle is shaken, the lead screw is rotated, thereby driving the movable tong body to move rapidly, and then controlling the opening and closing of the jaws. This structure can double the moving speed of the movable tong body.
