Abstract

The invention discloses a stroke adjustable oil cylinder which comprises a cylinder body, a cylinder head, a piston rod, a piston which is connected with the piston rod, and a rodless cavity oil opening. The stroke adjustable oil cylinder is characterized in that an installing seat is fixedly connected at the front end of the cylinder body, a worm and a worm gear which is meshed with the worm are arranged in the installing seat through bearings, a stroke positioning sleeve is arranged on the piston rod in sliding mode, the worm gear is connected with the stroke positioning sleeve through threads, the stroke positioning sleeve is arranged on the inner sides of the installing seat and the cylinder body, and a worm gear positioning sleeve is fixedly connected at the front end of the installing seat. The stroke adjustable oil cylinder has the advantages of being convenient to machine, and high in percent of pass. Meanwhile, a stroke is convenient and accurate to control, a stroke control part is not contacted with oil liquid, tightness is good, and leakage phenomenon is little.

Description

technical field [0001] The invention relates to an oil cylinder with adjustable stroke. Background technique [0002] At present, most of the stroke adjustable oil cylinders commonly used are equipped with a stroke adjustment rod on the cylinder head. The stroke adjustment rod is made of external thread, and the stroke adjustment screw sleeve is connected with the stroke adjustment rod through the internal thread. The stroke adjustment device is on the upper part of the cylinder, and the adjustment is extremely inconvenient. , and the stroke adjustment rod should be in contact with the oil in the cylinder body, more sealing structures need to be provided, the sealing performance is difficult to guarantee, and leakage often occurs. Contents of the invention [0003] The object of the present invention is to address the above-mentioned deficiencies in the prior art, to provide an adjustable stroke oil cylinder, which has the advantages of easy processing, high pass rate,...
