Description

Pneumatic centering vise

This invention provides a vise technology field, especially a pneumatic centring vise technology, in which the inner tapered blocks on both sides of the driving part are expanded and contracted by the elastic force of the elastic element, forcing the two jaws to maintain a normal clamping safety state. The piston and guide column are made separately, making the manufacturing and assembly easier. The piston and guide column are both equipped with O-rings to prevent air leakage.

According to the prior art case of application No. 112209392 "Pneumatic centring vise", a piston rod is provided inside a base, the upper end of the piston rod extends into the sliding space between the two slide rails above the base, and is connected to a brake block in the sliding space, and inclined wedge blocks are provided on both sides of the brake block; two slide blocks are provided in the sliding space, and the corresponding inner side surfaces of the two slide blocks are respectively concave with inclined guide grooves, so that the inclined wedge blocks of the brake block are embedded in the inclined guide grooves to drive the two slide blocks.

However, the above-mentioned known structure has a piston and a piston rod formed in one piece, so it is difficult to manufacture and assemble. The inclined guide groove and the inclined wedge block are designed as an outer cone that contracts upward and expands downward. The clamping state is achieved only when the pressure is pressed downward. Whether the clamping or release is controlled by high-pressure gas, it is unknown whether the workpiece is clamped. Therefore, processing without clamping the workpiece will cause dangerous situations such as the workpiece flying out. Moreover, after clamping, it is impossible to apply pressure to strengthen the clamping force, which is also one of the defects of the known structure.

Therefore, in view of the problems existing in the above-mentioned knowledge structure, how to develop a more ideal and practical innovative structure is what consumers are eagerly looking forward to, and it is also the goal and direction that relevant industries must work hard to develop breakthroughs.

In view of this, the creator, based on his many years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above-mentioned goals and finally obtained a truly practical creation.

The main purpose of this invention is to provide a pneumatic centring vise, in which the inner tapered blocks on both sides of the driving part that expand and contract upward are pushed up by the elastic force of the elastic element, forcing the two jaws to maintain a normal clamped safety state. The piston and guide post are made separately, making the manufacturing and assembly easier. The piston and guide post are both equipped with O-rings to prevent air leakage.

To achieve the above-mentioned purpose, the invention provides a pneumatic centring clamping vise, which includes: a vise body, a pneumatic cylinder is arranged at the center of the bottom surface of the vise body, a piston is arranged in the pneumatic cylinder, a bottom cover seals the pneumatic cylinder, a plurality of elastic elements are pressed against the top surface of the bottom cover and the bottom surface of the piston, a horizontal slide rail is arranged on the vise body, two slide blocks are horizontally slidable on the slide rail, and an inner tapered inclined groove that expands upward and contracts downward is arranged at the adjacent ends of the two slide blocks, the pneumatic cylinder penetrates to the slide rail and a through hole is arranged, a screw penetrates the piston , guide column, can be locked to the driving part, the driving part is provided with an inner tapered bevel block that expands and contracts upwards on both sides and slides to the inner tapered bevel grooves of the two slide blocks respectively, and the two jaws can be locked to the two slide blocks respectively according to the clamping width of the workpiece, and the piston and guide column are provided with leakproof O-rings. When there is no external force or high-pressure gas, multiple elastic elements push the driving part upwards, forcing the inner tapered bevel block that expands and contracts upwards to drive the two slide blocks of the inner tapered bevel groove of the driving tool to lean inward, so that the two jaws can maintain the normal clamping of the workpiece to ensure safety.
