Description
Technical Field
The utility model relates to the technical field of machining tool equipment for a movable column tube of a single hydraulic support used in a coal mine underground, in particular to a hydraulic lock closely following a tool rest.
Background
The single hydraulic prop is necessary equipment for supporting the working face and the roadway of the underground coal mine. Hundreds of thousands of them are needed every year in the country. The plunger is a key part of the single hydraulic prop and is formed by turning, grinding or rolling a 27SiMn seamless steel pipe after quenching and tempering heat treatment. The shaft workpiece with the ratio of the length L of the workpiece to the diameter d of the workpiece larger than 20 (namely L/d is larger than or equal to 20) is called as a slender shaft. Such parts are typically machined on a lathe. In the turning process, due to the low rigidity of the tool, the tool is influenced by factors such as cutting force, gravity, cutting heat and the like during turning, the defects such as bending deformation, vibration, taper, waist drum shape, bamboo joint shape and the like are easily generated, and the machining precision is difficult to ensure, so that the accuracy of relative movement of the tool and a part is damaged, the machined slender shaft generates a shape with thick middle and thin two ends, and the machining precision of the part is seriously influenced. When in cutting, a follow rest is required to support and stabilize a workpiece, and the follow rest is an essential accessory for processing a slender shaft. But there is no applicable follower rest on the numerically controlled lathe purchased from a machine tool factory.
