Embodiment Construction
[0011] The present invention will be further described in detail according to the drawings and embodiments. Such as figure 1 , figure 2 As shown, the limit oil cylinder semi-finished product 1 is made by the limit oil cylinder blank through lathe rough finishing and plane milling and other processes. It includes an inner circular hole 13, a round head 12 at one end, and a square head 10 at the other end. The part that is integrated with the square head 10 and the round head 12 is a cylinder 11 , and one end of the square head 10 is processed with a boss positioning notch 14 . Such as figure 1 , image 3 As shown, the processing technology of the limit oil cylinder semi-finished product 2 9 is basically the same as that of the limit oil cylinder semi-finished product 1 1. The difference is that a concave positioning stop 15 is processed at one end of the square head 10, and a concave positioning stop 15 is processed at one end of the round head 12. Machining is provided wi...

The invention relates to a method for processing a limiting cylinder. Firstly, a roughcast is processed to semifinished cylinders 1, 2 and 3 which comprise inner circular holes, square heads, circular heads, cylinders and positioning stops of convex stations and concave stations; the semifinished limiting cylinders 1 and 2 and the semifinished limiting cylinders 1 and 3 are connected into a whole respectively through bolts and nuts; the semifinished limiting cylinders 2 and 3 are connected into a whole through special inner and outer joints and mechanical bolts to form a four-kit combination body of the semifinished limiting cylinders; positioning chamfer angles on two ends and internal borings are machined on a lather and are detached one by one; and the semifinished cylinders are subjected to rough and finish machining to form the limiting cylinder through the lather. The method for machining the limiting cylinder can greatly improve machining efficiency and improve the machining precision of the inner circular hole, thereby improving the quality of a product.
Description
technical field [0001] The invention relates to a processing method of an oil cylinder, in particular to a production and processing technology of a limit oil cylinder. Background technique [0002] The limit oil cylinder is an auxiliary oil cylinder designed to limit the position of the concrete piston and quickly replace the concrete piston, which is installed behind the main oil cylinder of the concrete pump truck and the tow pump. The inner hole processing of the oil cylinder used to be bored on a lathe in a single piece, which was inefficient and the accuracy could not be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a processing method for a limit oil cylinder, which can not only improve the processing efficiency, but also ensure the processing accuracy. In order to achieve the above object, the present invention adopts the following technical solutions. [0004] It is made from the rough and fine machining of the ...
