Description

A handle operated clamp

technical field

The utility model relates to the field of mechanical processing, in particular to a handle-operated fixture.

Background technique

During mechanical processing, different mechanical clamping mechanisms are required for the clamping of different products. When processing workpieces, various processing machines often need to be replaced. The operation process is cumbersome, time-consuming and laborious, which seriously affects the efficiency of mechanical processing and increases It reduces the production cost of the enterprise and limits the possibility of the enterprise to expand reproduction.

Utility model content

The utility model aims to solve the problems of the above-mentioned prior art, and provides a handle clamp capable of conveniently clamping workpieces, which is easy to operate and saves time and effort.

The technical solution adopted by the utility model to solve its technical problems: the handle-operated fixture includes a clamp body, a support seat is provided at the left end of the clamp body, a handle is rotatably connected to the support seat, and a long groove along the axial direction is also provided on the handle. There is a movable pin in the long groove, one end of the pin is fixed on the pressure plate, the clamp body is connected with a bolt vertically penetrating through the pressure plate, the clamp body is fixed with a slanting block, and the pressure plate is provided with a lower end that fits on the slanting block. Movable pin, the bottom of the right end of the pressure plate is provided with a fixing piece that presses on the part. Here, the fixing piece fixes the workpiece. When working, push the handle to the right to make the pin move in the long groove and drive the pressure plate fixed on the handle;

Further improvement, the handle is connected to the support seat through the rotation of the positioning pin;

Further improvement, the top of the inclined block is provided with an inclined surface, and the movable pin is pressed against the inclined surface;

Further improvement, the bottom contact end of the movable pin is arc-shaped, here setting the bottom of the movable pin to be arc-shaped can better make the movable pin move on the inclined block;

Further improvement, the bolt is covered with a spring, and the upper and lower ends of the spring are respectively pressed against the pressure plate and the clamp body. After the handle is pushed to drive the pressure plate, the adjustment bolt cooperates with the positioning pin to adjust the pressure plate, and the bolt is under the action of the spring. Pressure, so that the fixing part can be better pressed on the work piece;

Further improvement, there is a ball-and-socket washer between the pressure plate and the bolt, which protects the surface of the pressure plate from being scratched by the bolt and disperses the pressure of the bolt on the pressure plate;

Further improvement, the contact end of the fixing piece is a tapered structure, and the fixing piece is arranged symmetrically according to the front and back of the part. Here, setting the contact end of the fixing piece as a tapered structure can better exert pressure on the workpiece. Symmetrical setting can better clamp the workpiece.

The beneficial effects of the utility model are: the utility model is reasonable in structure, ingenious in design, and convenient in operation. While ensuring convenient clamping of the workpiece, the work efficiency is improved, and the time for positioning and clamping is saved.
