Profiled air cylinder

Abstract

The invention provides a profiled air cylinder which is provided with an air cylinder barrel, an air cylinder end cover connected with the air cylinder barrel, a piston arranged in the air cylinder barrel, a piston rod connected with the piston and a spring arranged on the piston rod, wherein the shape of the inner cavity of the air cylinder barrel is set as a long circle; the shape of the piston is set as a long circle; the piston is matched with the air cylinder barrel; a long-circular long shaft L passing the center is 35mm; a long-circular short shaft D passing the center is 28mm; a long-circular sealing gasket is arranged between the air cylinder end cover and the air cylinder barrel; a bearing is arranged in the piston; and the piston is provided with a cushion pad. In the invention, since the shapes of the air cylinder barrel and the piston of the profiled air cylinder are respectively set as the long circle, the effective area is increased, and thereby, the thrust of the profiled air cylinder can be increased without changing the distance 32mm between the shafts.

Description

technical field [0001] The invention relates to the field of woodworking machinery row drills, in particular to a special-shaped cylinder for woodworking machinery row drills. Background technique [0002] With the development of science and technology, the application of wood processing centers in the field of wood processing is becoming more and more common. In the prior art, the inner cavity of the drill bit cylinder of the wood processing center is generally cylindrical, and the piston disposed in the cylinder is also generally circular. [0003] During processing, the distance between two adjacent pin holes of panel furniture is generally 32mm, so the distance between two adjacent drill shafts (that is, cylinder piston rods) on the row of drill bits is generally 32mm, and the diameter of the inner cavity of the cylinder is generally 28mm. With this size structure, when processing ordinary plates, the pressure of the cylinder can meet the processing needs. However, whe...

AI Technical Summary

Problems solved by technology

However, when processing hard plates, often due to insufficient thrust of the cylinder, there will be a phenomenon of giving up the knife, resulting in the processed parts not meeting the requirements

If the diameter of the cylinder is increased, although the thrust of the cylinder can be increased, due to the limitation of the space of the row of drill bits in the wood processing center, the cylinders will interfere with each other and the cylinder cannot be installed.
