Abstract
The utility model relates to a piston rod which comprises a reciprocating rod arranged in a cylinder body and a sleeve arranged on the reciprocating rod. The upper end face, located outside the cylinder body, of the reciprocating rod, is fixedly connected with the outer side wall of the sleeve. According to the technical scheme, the piston rod is simple in structure, and due to the piston rod of the assembly structure that the sleeve is welded to the reciprocating rod, operation stability of an oil cylinder is increased and meanwhile machining difficulty is reduced.
Description
Technical field
The utility model relates to a kind of piston rod.
Background technique
As shown in Figure 1, offer attachment hole 3 in the prior art on the piston rod 1, attachment hole 3 is connected with bearing pin, and the bearing pin motion drives piston rod 1 in cylinder body 10 interior to-and-fro motion.For perforate on piston rod 1, need the length of eye-bolt shaft 1, and directly large in piston rod 1 processing attachment hole 3 technology difficulty, equipment requirement is high.And the attachment hole 3 of processing is connected contact with bearing pin little, poor stability.
The model utility content
Technical problem to be solved in the utility model is attachment hole processing difficulties on the piston rod, and poor work stability in order to overcome above deficiency, provides a kind of piston rod.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: described piston rod comprises the rocker arm that is arranged in the cylinder body and the sleeve pipe that is arranged on the rocker arm, and the upper-end surface that described rocker arm is positioned at outside the cylinder body is fixedly connected with the outer side wall of sleeve pipe.
Further, described upper-end surface and outer side wall are by being welded to connect.
Further, the axis of the axis of described sleeve pipe and cylinder body is perpendicular.
Further, described cylinder body comprise end sealing pipe and with the cavity of rocker arm Spielpassung.
Further, the diameter of described sleeve pipe is less than the diameter of rocker arm, and the length of described sleeve pipe is between the diameter and diameter of cylinder of rocker arm.
The technological scheme that the utility model provides is simple in structure, and the piston rod of this package assembly of soldering sleeve on rocker arm has reduced difficulty of processing in the stability that increases the oil cylinder operation.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As illustrated in fig. 1 and 2, piston rod described in the utility model comprises the rocker arm 2 that is arranged in the cylinder body 10 and the sleeve pipe 3 that is arranged on the rocker arm 2, and the upper-end surface 21 that described rocker arm 2 is positioned at outside the cylinder body is fixedly connected with the outer side wall 31 of sleeve pipe 3.
Described cylinder body 10 comprise end sealing pipe 11 and with the cavity 12 of rocker arm 2 Spielpassung.
The axis of the axis of described sleeve pipe 3 and cylinder body 10 is perpendicular.
The diameter d of described sleeve pipe 3
3Diameter d less than rocker arm 2
2, the length L of described sleeve pipe 3 is between the diameter d of rocker arm 2
2With cylinder body 10 diameter d
1Between.
Assembly process is as follows:
First the Socket welding that processes is connected on the upper-end surface of rocker arm, then rocker arm is inserted in the cylinder body, further sleeve pipe is connected with bearing pin again.
