Technical Field
The invention belongs to the field of mining support columns, and particularly relates to a tool for cladding an inner wall of an outer cylinder barrel of a column and a cladding method thereof.
Background
The outer cylinder barrel of the stand column for the coal mine support has the defects of corrosion, pitting corrosion, strain and the like on the inner sealing surface after being used for a period of time, so that the sealing is failed and discarded, and in order to recycle the cylinder barrels, the service life of the cylinder barrels can be prolonged by 3-5 times by adopting the repair process of melting copper alloy on the sealing surface.
The inner diameter needs to be machined for a plurality of times by getting on and off a lathe, and an outer reference surface taking the axis of an inner sealing surface as a reference is needed. Generally, the process needs to remove accessories outside the cylinder, cut off the cylinder bottom, weld the accessories and the cylinder bottom after the inner sealing surface is cladded and repaired before cladding, and thus, time and labor are wasted.
Disclosure of Invention
The invention aims to more efficiently and accurately clad the inner wall of the outer cylinder barrel of the upright column, and further provides a tool for cladding the inner wall of the outer cylinder barrel of the upright column and a cladding method thereof.
The invention adopts the following technical scheme:
the utility model provides a frock for stand outer cylinder melts and covers inner wall, includes four-jaw chuck, centre frame and lathe tailstock on lathe and the installation lathe, and the outer cylinder horizontal support of stand is installed on the centre frame supports, still including welding the cylinder end circle at the outer cylinder bottom of the cylinder of stand, and the cylinder end circle is the ring column structure, and cylinder end circle end is connected by four-jaw chuck chucking, is connected with the extension bar that can the level stretch into in the outer cylinder of stand on the lathe tailstock, and the extension bar end is connected with the percentage table.
The specific cladding steps are as follows:
1) taking the outer surface of the outer cylinder barrel of the upright post as a reference for alignment, and welding a cylinder bottom ring on the cylinder bottom of the outer cylinder barrel of the upright post;
2) the four-jaw chuck supports the inner diameter of the cylinder bottom ring, and a central frame supporting upright post outer cylinder barrel is erected at the right end;
3) an extension bar with a dial indicator is arranged in a lathe tailstock;
4) shaking the lathe tailstock, extending the dial indicator into the outer cylinder of the upright post, and stopping when the distance between the dial indicator and the cylinder bottom of the outer cylinder of the upright post is about 100 mm;
5) pressing the cross dial indicator on the inner sealing surface of the outer cylinder barrel of the upright post, rotating the lathe chuck, adjusting the center of the four-jaw chuck, and turning the excircle of the bottom ring of the cylinder when the swinging amount of the cross dial indicator is less than 0.06 mm;
6) and after the cylinder bottom ring is turned, the outer circle of the cylinder bottom ring is clamped by using the three-jaw chuck as a reference, and cladding is carried out on the inner wall of the outer cylinder barrel of the upright post.
According to the invention, the cylinder bottom ring is welded on the bottom of the outer cylinder barrel of the upright post, and then the axis datum of the inner sealing surface of the outer cylinder barrel of the upright post is guided to the outer circle of the cylinder bottom ring through turning alignment, so that cladding is carried out by using the cylinder bottom ring as a clamping datum, the outer accessories and the cylinder bottom on the outer cylinder barrel of the upright post do not need to be disassembled in the whole process, and the repairing efficiency and accuracy are higher.
