Abstract

The invention provides a technical scheme of a pull boring processing method and device of a cylinder barrel of a thin-walled slender hydraulic cylinder. The device comprises a lathe bed and a cooling device arranged on one side of the lathe bed, wherein a headstock with a first external control box is arranged at one end of the lathe bed, and a power box with a second external control box is arranged at the other end of the lathe bed. The scheme is characterized in that a hydraulic control bracket is further arranged on the lathe bed, and the power box is fixedly connected with a taper pull broaching and boring rolling head through a pull rod. According to the scheme disclosed by the invention, the problems of rigidity of a push boring rod, processing precision and the like are solved, the surface quality of the cylinder barrel can be greatly improved, and the technical scheme is especially suitable for the cylinder barrel, of which the inner diameter is less than 80mm, of the hydraulic cylinder.

Description

technical field

[0001] The invention relates to the field of oil cylinder barrel processing, in particular to a thin-walled and slender hydraulic cylinder barrel drawing and boring processing method and device. Background technique

[0002] In the prior art, it is known that the oil cylinder is the main executive component of construction machinery, and now most oil cylinder production companies usually perform push-boring processing. The method has the advantages of simple structure, convenient feeding and processing. But when the inner diameter of the pipe is less than 80mm, the boring bar is slender. If the push boring method is adopted, the boring bar is too thin and the rigidity is insufficient, which will cause vibration, difficulty in chip removal, easy cutting, short tool life, difficult to guarantee machining accuracy, and pipe wall thickness. Unevenness even penetrates the pipe wall, so many manufacturers use honing when processing slender bores, but the honing pr...

Embodiment Construction

[0017] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0018] As can be seen from the accompanying drawings, a thin-walled and slender hydraulic cylinder barrel broaching and boring processing method of the present program includes the following steps:

[0019] A thin-walled and slender hydraulic cylinder barrel drawing and boring processing method comprises the following steps:

[0020] a. Put the thin-walled and slender hydraulic cylinder cylinder blank on the hydraulic control bracket of the drawing and boring processing device, adjust the center height of the hydraulic cylinder cylinder blank with the hydraulic control bracket, and pass the pull rod of the drawing and boring processing device through the cylinder barrel blank;

[0021] b. Install a tapered broaching and boring head on the pull rod, and connect a high-pressure liquid...
