Problems solved by technology
However, the cushioning effect of this solution is not ideal. During the repeated operation of the oil cylinder, the impact force of the piston rod on the cylinder body is still relatively large, which is prone to mechanical failure and shortens the service life of the oil cylinder.

Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0014] Such as figure 1 As shown, the buffer mechanism of the guide sleeve of the hydraulic cylinder is arranged between the cylinder body 1 and the guide sleeve 2, and the piston rod 3 pierced in the guide sleeve 2, and an annular groove 21 is provided on the outer wall of the guide sleeve 2. A buffer chamber 22 is provided inside the guide sleeve 2, a first oil hole 23 and a second oil hole 24 are opened on the annular groove 22, and an adjustment hole 25 is opened at one end of the guide sleeve 2, and the adjustment holes 25 are distributed in the buffer chamber. On the peripheral periphery of 22 , the first oil hole 23 communicates with the buffer cavity 22 , and the second oil hole 24 communicates with the regulating hole 25 .
[0015] Specifically, the adjustment hole 25 and the buffer cavity 22 are parallel to each other. The...

The invention belongs to the technical field of mechanical equipment, and relates to a buffer mechanism, in particular to a hydraulic oil cylinder guide sleeve buffer mechanism. The technical problemthat the design is unreasonable in the prior art is solved. The hydraulic oil cylinder guide sleeve buffer mechanism is arranged among a cylinder body, a guide sleeve and a piston rod penetrating in the guide sleeve, and is characterized in that an annular groove is formed in the outer wall of the guide sleeve, a buffer cavity is arranged in the guide sleeve, the annular groove is provided with afirst oil hole and a second oil hole, one end of the guide sleeve is provided with an adjusting hole, the adjusting hole is distributed in the periphery in the circumferential direction of the buffercavity, the first oil hole communicates with the buffer cavity, and the second oil hole communicates with the adjusting hole. The hydraulic oil cylinder guide sleeve buffer mechanism has the advantages of being reasonable in design, simple in structure, good in buffer effect, good in working stability, long in service life and the like.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a buffer mechanism, in particular to a hydraulic oil cylinder guide sleeve buffer mechanism. Background technique [0002] Mechanical automation is the development direction of modern machinery, and hydraulic technology is the basis for realizing mechanical automation. A hydraulic cylinder generally includes a cylinder body, a piston, a piston rod and a guide sleeve, and the piston rod moves back and forth. In the prior art, many oil cylinders are equipped with a buffer device at the end of the stroke, but the essence is to add a section of mating surface at the front and back of the piston to play the role of buffer stroke; to a certain extent, it reduces the impact of the piston rod on the rod body. Impact force, but when the piston rod or the corresponding matching parts are subjected to a very large lateral impact force, the mating surface is likely to cause misal...
