Machining technology of cylinder barrel of steering oil cylinder

Abstract

The invention discloses a machining technology of a cylinder barrel of a steering oil cylinder and belongs to the field of hydraulic oil cylinders. The machining technology comprises the main steps that of (1) blanking, (2) turning, (3) support welding, (4) milling, (5) drilling, (6) machining of an inner hole and (7) forming of a semi-finished product. In the step of support welding, the mode of semi-automatic welding with protection is adopted, the working efficiency and the machining precision are improved, and welding is safer. The step of inner hole turning and the step of honing are combined through a deep hole boring machine, inner hole turning and honing are conducted at the same time, the surface smoothness and the surface hardness of the inner hole are improved, and the errors of the inner diameter are reduced; besides, the procedure is simplified, and efficiency is improved.

Description

technical field

[0001] The invention relates to a processing technology of a steering oil cylinder barrel, belonging to the field of hydraulic oil cylinders.

[0002] Background technique

[0003] The processing of the cylinder barrel of the steering cylinder mainly adopts the following steps: blanking, turning the outer circle, welding the bracket, milling, drilling, turning the inner hole and honing, but this process needs to be improved, and the welding bracket generally uses manual The welding method, purely manual welding is not efficient, and because the artificial control of the welding speed is not reliable, resulting in uneven welds; in addition, the inner hole and honing are carried out separately, and these two steps are carried out separately. On the other hand, the processing accuracy is not high; and honing generally uses sandpaper, which makes the inner wall finish not high, and also leads to uneven inner diameter.
