Description

Long-stroke parallel mechanical clamp air guide mechanism

Technical Field

The utility model relates to a pneumatic cylinder, in particular to a long-stroke parallel mechanical clamp air guide mechanism.

Background

The internal structure of the commercial pneumatic cylinder is guided to the internal passage through the external air pressure input, and the corresponding piston is driven by air pressure to perform repeated displacement action, so that the purpose of use is achieved.

The manufacturing and processing technology of the pneumatic cylinder with the common size is quite mature in the field, but if the pneumatic cylinder with the larger size is used in the drilling process, the pneumatic cylinder is easy to cause the breakage of the drill bit or the insufficient length of the drill bit, the drilling is required to be carried out at the front end and the rear end, and the internal passage is easy to have errors, so that the processing is relatively difficult.

The existing solution to the above problem generally uses a multi-stage internal passage design, and after the relatively simple passage is cut into different lengths, the relatively simple passage is connected by adding the passages, so that the difficulty of drilling can be reduced, and the time cost of the drilling can be effectively controlled.

Although some improvements have been made to the process simplification in the alternative to adding a somewhat complex pathway, other improvements appear to exist and, therefore, the present inventors have continued to study and make improvements.

The air guide cushion sheet is embedded in the first channel and the second channel in a matching way, and is fixedly connected with the body by matching with a plurality of screws corresponding to an air guide cover plate to form a whole;

When the air pressure source is input into the A channel through the A air hole of the body, the A piston and the C piston generate displacement, so that the air pressure source passes through the A air hole in the first channel to the D air hole, and the B piston and the D piston are synchronously driven to move together in the reverse position; when the air pressure source is input into the B channel through the B air hole of the body, the B piston and the D piston generate displacement, so that the air pressure source can synchronously drive the A piston and the C piston to move together in reverse positions through the B air hole and the C air hole in the second channel, and the repeated circulation of the A channel and the B channel can effectively drive the clamping jaw below the body to repeatedly clamp and relax.

Optionally, the first channel and the second channel are in a staggered design.

Optionally, the first channel and the second channel are in an X-shaped design.

Compared with the existing solving means, the structure of the air guide cushion is that the existing common internal passage is processed through the outside of the body, so that the problem of drilling of the air passage can be directly improved, the internal passage can be more effectively guided to the outside of the body by matching with the air guide cushion sheet, the internal passage is guided back to the inside of the body again to drive the pistons related to the passage to alternately displace, the lower clamping jaw driven by the body can be more smooth, and the problems of the existing processing and the complicated passage can be effectively improved.
