Description
Technical Field
The utility model relates to a cylinder especially relates to a three-rod cylinder.
Background
In a traditional cylinder, a piston rod of the traditional cylinder rotates during working, and a workpiece also rotates along with the piston rod, so that the position of the workpiece changes; when the work environment does not allow the workpiece to rotate, the traditional air cylinder cannot be used; in the traditional cylinder, the connection modes between the piston and the piston rod and between the rear end cover and the cylinder body are not reasonable, so that the processing speed is low and the connection is not firm.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a piston rod and front baffle can not rotate, and the firm three-rod cylinder is connected between piston and the piston rod and between rear end cap and the cylinder body.
A three-rod air cylinder comprises a front baffle, an air cylinder seat, guide sleeves, two guide rods, a front end cover, a rear end cover, a cylinder body, a piston and a piston rod, wherein the front baffle is connected with the piston rod and the two guide rods; the cylinder body is fixed on the cylinder seat, the front end cover and the rear end cover are fixed at the front end and the rear end of the cylinder body, the piston is installed in the cylinder body, and the piston is connected with the piston rod.
Furthermore, the front baffle is connected with the piston rod and the two guide rods through the inner hexagon screws.
Furthermore, the front end cover is fixed at the front end of the cylinder body through a check ring for holes, and a sliding sleeve is installed between the front end cover and the piston rod.
Furthermore, cushion pads are arranged on the front end surface and the rear end surface of the piston.
Furthermore, a workpiece mounting surface is arranged on the outer side of the front baffle, and a plurality of mounting holes are formed in the workpiece mounting surface.
Further, the piston is connected with the piston rod in a riveting mode.
Further, the rear end cover is fixed in the rear end of the cylinder body in an extruding mode.
The utility model has the advantages that: the three rods are composed of a piston rod and two guide rods, the piston rod drives the front baffle to move linearly back and forth, and the two guide rods can synchronously move linearly in the guide sleeve when the front baffle moves; the front baffle and the two guide rods limit the piston rod to rotate, so that the piston rod is kept at the same position, and the workpiece is mounted on the workpiece mounting surface of the front baffle, so that the air cylinder can be applied to occasions where the workpiece is not allowed to rotate.
Drawings
The present invention will be further explained with reference to the drawings and examples.
