Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of keyway positioning devices, in particular to a positioning device for a keyway of a welded pipe roller wire cutting. Background Art
[0002] In actual applications, the end faces of some welded pipe rolls are evenly distributed with 4-6 screw holes that have a relative position relationship with the inner hole keyway. Some of them are at an angle of 45° to the keyway, and some are at an angle of 30°. These angles must be strictly controlled to ensure that other accessories can be smoothly assembled on the roll. The roll keyway is processed by wire cutting, which can basically achieve high precision, including width, depth, symmetry, and roughness. However, if it is processed before quenching, the width and depth of the keyway should consider the quenching deformation and processing allowance. The quenching deformation of the roll is affected by many factors, such as material, shape, batch, etc., so it is difficult to master. In order to prevent the width from exceeding the tolerance, it is generally processed smaller before quenching, and then manually polished after quenching. The consistency of the entire key width is poor; the symmetry of the keyway is even more difficult to guarantee. After quenching, the inner hole must be fine-machined once by turning and once by grinding. Each alignment and processing may affect it.
[0003] In the prior art, when in use, the roller is placed on the limit pin on the top of the steel plate to fix it, and the position of the fixing frame is fine-tuned by adjusting the mounting block on one side of the fixing frame, thereby accelerating the keyway positioning.
[0004] However, in actual use, the height of the fixed frame moves, and when the height of the roller is low and the lowering height of the cutting head is not enough, a gasket needs to be placed at the bottom of the fixed frame, which will cause inconvenience during cutting. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a positioning device for the keyway of the welded pipe roller wire cutting, which solves the problem that the height of the fixed frame moves during actual use, and when the height of the roller is low and the lowering height of the cutting head is not enough, a gasket needs to be placed at the bottom of the fixed frame, which causes inconvenience during cutting.
[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a positioning device for wire cutting keyway of a welded pipe rolling roller, comprising a rolling roller, a positioning pin is inserted in the bottom of the rolling roller, a fixing plate is fixedly connected to the bottom of the positioning pin, a placing shell is inserted in the outer wall of the rolling roller, the bottom of the placing shell is fixedly connected to the top of the fixing plate, a base is arranged below the fixing plate, the bottom of the fixing plate is fixedly connected to a telescopic column, the bottom of the telescopic column is installed on the top of the base, a lifting structure is installed on the top of the base, the lifting structure comprises a turning handle, a bidirectional screw rod, a sliding block and a tilting block, the outer wall of the bidirectional screw rod is rotatably connected to the inner wall of the base through a bearing, one end of the bidirectional screw rod extending to the outer wall of the base is fixedly connected to the turning handle, the outer wall of the bidirectional screw rod is movably connected to a sliding block, the outer wall of the sliding block is slidably clamped to the inner wall of the base, the top of the sliding block is fixedly connected to the tilting block, and the top of the tilting block is tightly against the bottom of the fixing plate.

[0008] Preferably, a rubber pad is pressed against the bottom of the fixing plate, the inner wall of the rubber pad is inserted into the outer wall of the telescopic column, and the bottom of the rubber pad is fixedly connected to the top of the fixing column.
[0009] Preferably, a mounting plate is fixed on the top of the fixed plate, the inner wall of the mounting plate is movably connected to a threaded rod, one end of the threaded rod is rotatably connected to a fixed block, the outer wall of the fixed block is fixedly connected to a top block, the outer wall of the top block is tightly pressed against the outer wall of the roller, and the other end of the threaded rod is fixedly connected to a handle.
[0010] Preferably, the outer wall of the fixing block is fixedly connected to a limiting column, and the outer wall of the limiting column is plugged into the inner wall of the mounting plate.
[0011] The utility model has the following beneficial effects: the positioning device for the wire cutting keyway of the welded pipe rolling roller cooperates with the bidirectional screw rod, the slider and the tilting block. When adjusting the height of the rolling roller, the turning handle is used to drive the bidirectional screw rod to rotate, and the slider drives the tilting block to move toward the bottom of the fixed plate through engagement with the slider. Under the action of the slope on the surface of the tilting block, the fixed plate raises the height of the rolling roller, which solves the problem that when the prior art is used, a gasket needs to be placed at the bottom of the fixed frame, which causes inconvenience in cutting.

[0023] In the specific implementation process, it is worth pointing out that, under the cooperation of the bidirectional screw rod 9, the slider 10 and the tilting block 7, when adjusting the height of the roller 1, the turning handle 11 is used to drive the bidirectional screw rod 9 to rotate, and through the engagement with the slider 10, the slider 10 drives the tilting block 7 to move to the bottom of the fixed plate 2, and under the action of the slope of the surface of the tilting block 7, the fixed plate 2 raises the height of the roller 1;
[0024] Furthermore, the outer wall of the telescopic column 16 is movably connected to the fixed column 12, and the outer wall of the telescopic column 16 extending to the inside of the fixed column 12 is sleeved with a spring 15, the bottom of the spring 15 is pressed against the outer wall of the telescopic column 16, and the top of the spring 15 is pressed against the top of the inner wall of the fixed column 12, and the bottom of the fixed column 12 is fixedly connected to the top of the base 8;
