Problems solved by technology

[0002] The piston of the double-acting cylinder is also provided with a reset rest position between the two limit positions in the chamber. In the prior art, springs and other similar elastic members are generally used to connect to the piston to assist in reset. However, in practical applications, springs and other similar Due to their own inertia and restoring force, the elastic members cannot return to the rest position in a short time, and these elastic members will wear out after repeated use, shortening the service life of the cylinder, and when it is necessary to modify the stroke working parameters of the cylinder, it is necessary to Changing the elastic member with complex structure makes the adjustment and calibration very cumbersome. Therefore, it is necessary to provide an industrial double-acting cylinder to solve the above problems

Embodiment 1

[0020] Such as Figure 1 to 3 As shown, an industrial double-acting cylinder includes a front cylinder head 1, a connecting barrel 2, a cylinder 3, a rear cylinder cover 4, and a piston rod 5, and the front cylinder head 1 is mounted at the front end of the connection cartridge 2, the connection The cartridge 2 and the rear cylinder cover 4 are respectively mounted on both ends of the cylinder 3, and the cylinder 3 is provided with a chamber 6, and the piston rod 5 extends to the chamber 6, and the other end passes through the connecting barrel 2 and The front cylinder head 1, the chamber 6 is provided with a piston 7 in the inner wall thereof, and the piston 7 is attached to one end of the piston rod 5, and the connecting barrel 2 and the cylinder bar are respectively provided. 8 and the air port 4 and it is connected to the chamber 6, and the cylinder also has a stability when the piston 7 is moved, and the auxiliary component 10 that can assist the piston 7 is quickly reset to t...

Embodiment 2

[0027] Such as Figure 4 As shown, in relation to the first embodiment, the adjusted block 21 is not mounted in the end portion of the auxiliary piston 16, but is a threaded hole in the end portion of the auxiliary piston, and the screw 22 is threaded in the threaded hole.

[0028] Inlet 1 8, the intake port 2 9 and the intake port 3 19 are connected to the compressed air source, and the intake port three 19 has been connected to the compressed air source.

[0029] Working process and principle: By transporting the compressed air by an intake port 2 9, the piston 7 can be slid in the chamber 6, and it is now assumed that the intake port 2 9 intake to the chamber 2 13, The piston 7 slides to the left limit position in the chamber 6 (eg figure 1 As shown in, the intake port 3 19 feeds the compressed air into the chamber B18 and the gas line 20, and the compressed air is supplied into the chamber A17 via the gas line 20, so that the two auxiliary piston 16 give the piston rod A14, res...

Abstract

The invention discloses an industrial double-acting air cylinder and relates to the field of air cylinders. The industrial double-acting air cylinder comprises a front cylinder cover, a connecting cylinder, a cylinder barrel, a rear cylinder cover and a piston rod; the air cylinder is further provided with an auxiliary assembly and an air path assembly; the auxiliary assembly improves the stability of a piston during movement and can assist the piston to quickly reset to a static position; and the air path assembly provides an air source for the auxiliary assembly. By means of the arrangement, the limiting position of the piston can be adjusted without adjusting working parameters of the air cylinder or complex adjustment and calibration; high universality and easy adjustment are achieved; the problem that a practical elastic component of a double-acting air cylinder in the prior art cannot return to a static position in time in a short time due to self inertia and restoring force is solved; and meanwhile, compared with the existing double-acting air cylinder using an elastic component, part abrasion is avoided, and the service life is prolonged.

Description

Technical field [0001] The present invention relates to the field of cylinders, and more particularly to an industrial bifurcated cylinder. Background technique [0002] The piston of the double-acting cylinder is also provided in the middle of the two limit locations in the chamber, and the prior art generally uses a spring or other elastic member to be connected to the piston, the auxiliary reset, however, the actual application, spring, etc. The elastic member cannot return to the stationary position in a short time due to its own inertia and recovery force, and the elastic member will generate wear, and the life of the cylinder is shortened, and when it is necessary to modify the stroke of the cylinder, it is necessary Change the complex elastic member of the structure so that the adjustment and calibration is very cumbersome, so there is a need to provide an industrial double-acting cylinder to solve the above problems. Inventive content [0003] In order to solve the above...
