AI Technical Summary
Existing cutting runner fixtures require the production of special auxiliary fixtures for each type of runner, resulting in low processing efficiency and high manufacturing cost.
A pneumatic clamp for cutting runners is designed, including a positioning mechanism and a clamping mechanism. The positioning mechanism achieves rapid positioning through the L-shaped clamping block and the slide chute, and the clamping mechanism uses cylinders and push blocks to ensure stable clamping. The clamps can be replaced according to the shape of the runner, avoiding the need to make a complete set of equipment for each type of runner.
This achieves efficient clamping without the need to make special fixtures for each type of runner, improving processing efficiency and reducing production costs.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pneumatic clamps, in particular to a pneumatic clamp for cutting runners. Background Art
[0002] In the melt casting process, after the workpiece is cast, the runner connected to the workpiece needs to be cut off. Usually, when cutting the runner, the workpiece and the runner need to be clamped and fixed to facilitate the cutting operation. Since the runner size and position of each workpiece are different, cutting different types of runners is complicated. When cutting, a special auxiliary fixture needs to be made for each type of runner, resulting in low processing efficiency and high manufacturing cost. Summary of the invention
[0003] In view of the shortcomings of the existing fixture for cutting runners, which requires the production of special auxiliary fixtures for each type of runner during cutting, resulting in low processing efficiency and high manufacturing cost, the utility model provides a pneumatic fixture for cutting runners, which does not require the production of special auxiliary fixtures for each type of runner, has high clamping efficiency and low cost.
[0004] A pneumatic clamp for cutting a runner, which comprises a base plate, on which a vertical plate is installed, and is characterized in that: it also comprises a positioning mechanism and a clamping mechanism, the positioning mechanism comprises a clamping block installed on the front end surface of the vertical plate, the clamping block is L-shaped, the end of the transverse section of the clamping block is installed on the vertical plate, and the vertical section of the clamping block is provided with a slide groove; the clamping mechanism comprises a cylinder installed on the rear end surface of the vertical plate, the piston rod of the cylinder passes through the vertical plate and extends out of the front end surface of the vertical plate, the piston rod of the cylinder can be rotatably connected to one end of a first connecting rod, the other end of the first connecting rod is fixedly connected to the bottom end of a connecting shaft, the top end of the connecting shaft is fixedly connected to one end of a second connecting rod, the other end of the second connecting rod can be rotatably connected to one end of a push block, and the other end of the push block can be slidably installed in the slide groove.
[0005] It is further characterized by:
[0006] The longitudinal section of the push block is convex, and the slide groove matches the shape of the push block;
[0007] The clamp block has multiple models, and the clamp block can be replaced with different models according to the runner that needs to be clamped;
[0008] The connecting shaft can be rotatably mounted on the inverted L-shaped bracket, and the inverted L-shaped bracket is fixedly mounted on the bottom plate.
[0009] In the above structure of the utility model, the setting of the positioning mechanism can realize the rapid positioning of the runner by placing it on the clamping block, thereby improving the processing efficiency. At the same time, the positioning mechanism has a simple structure and reduces the manufacturing cost. The push block and the vertical plate of the clamping mechanism constitute the clamping of the runner. The push block slides in the fixed slide groove to prevent the push block from slipping, ensuring the consistency of the clamping position each time, ensuring the stability of the clamping, and improving the processing efficiency from the perspective of ensuring stability. For runners of different shapes, it is only necessary to replace the clamping blocks of different shapes to achieve the clamping of runners of different shapes. There is no need to make a new set of equipment for each type of runner. It is convenient and fast, further improving the processing efficiency and reducing the production cost.
