Description

Technical Field

[0001] The utility model relates to the technical field of cylinder production, in particular to a steel pipe inner bore cleaning device for cylinder production. Background Art

[0002] Before cutting seamless steel pipes, the inner bore of the steel pipe needs to be polished and smooth to remove impurities. The existing inner bore cleaning method is to put the steel pipe on the outside of a grinding wheel with a long rod, use a motor to drive the long rod to rotate, so that the grinding wheel grinds the inner bore of the steel pipe, and the operator manually drags the steel pipe so that the inner bore of the steel pipe can be evenly polished by the grinding wheel. After grinding, use a brush with a long rod to clean the impurities inside the steel pipe.

[0003] However, manually dragging the steel pipe has low precision and cannot ensure that the inner bore of the steel pipe is polished evenly. Only one steel pipe can be polished at a time. In addition, the impurities inside the steel pipe must be manually cleaned, resulting in high labor costs and low efficiency. Utility Model Content

[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0017] like Figure 1-4The steel pipe inner bore cleaning device for cylinder production shown in the figure comprises a workbench 1, a drive box 2 is fixedly installed on the top of the workbench 1, a worm wheel 12 is installed inside the drive box 2, a threaded tube 14 is fixedly installed at the center of the worm wheel 12, the end of the threaded tube 14 is connected to the outer wall of the drive box 2 through a bearing, a threaded rod 3 is threadedly connected inside the threaded tube 14, both ends of the threaded rod 3 extend out of the drive box 2, grinding wheels 7 are fixedly installed at both ends of the threaded rod 3, a worm 13 is meshedly installed above the worm wheel 12, the end of the worm 13 is connected to the outer wall of the drive box 2 through a bearing, a motor 10 is fixedly installed on the outer wall of the drive box 2, and the output end of the motor 10 is fixedly connected to the end of the worm 13. The operator sets two steel pipes of the same length on the grinding wheels 7 at both ends of the threaded steel. In the initial state, the grinding wheel 7 at one end of the threaded rod 3 is close to the drive box 2, and the grinding wheel 7 at the other end is far away from the drive box 2. After the steel pipe is sleeved, the grinding wheel 7 far from the drive box 2 is located at one end of the steel pipe far from the drive box 2, and the grinding wheel 7 close to the drive box 2 is located at one end of the steel pipe close to the drive box 2. The outer wall of the grinding wheel 7 fits the inner wall of the steel pipe.

[0018] Support platforms 11 are provided on both sides of the drive box 2. Both support platforms 11 are fixedly mounted on the workbench 1. Threaded holes are provided on the outer walls of the support platforms 11. The threaded rod 3 passes through the support platforms 11 and is threadedly connected with the threaded holes of the support platforms 11. The motor 10 drives the worm 13 to rotate, the worm 13 drives the worm wheel 12 to rotate, the worm wheel 12 drives the threaded tube 14 to rotate, the threaded tube 14 drives the threaded rod 3 to rotate, and the threaded rod 3 drives the grinding wheel 7 to rotate to grind the inner wall of the steel pipe. Because the threaded rod 3 is threadedly connected to the support platform 11, the threaded rod 3 will drive the grinding wheel 7 to move inside the steel pipe when it rotates. The motor 10 first rotates forward, so that the grinding wheel 7 close to the drive box 2 moves toward the end of the steel pipe away from the drive box 2, and the grinding wheel 7 away from the drive box 2 moves toward the end of the steel pipe close to the drive box 2, so that the inner walls of the two steel pipes can be completely polished at the same time.

[0019] A mounting frame 4 is provided on one side of the two support platforms 11 away from the drive box 2. The mounting frame 4 is fixedly mounted on the workbench 1. An arc groove is provided on the upper outer wall of the mounting frame 4. Cylinders 9 are fixedly mounted on the outer walls on both sides of the mounting frame 4. A pressing plate 8 is provided above the mounting frame 4. Both ends of the pressing plate 8 are fixedly connected to the output end of the cylinder 9. In the initial state, the output end of the cylinder 9 is in an extended state, and the steel pipe is sleeved on the grinding wheel 7 between the pressing plate 8 and the mounting frame 4, and one end of the steel pipe fits against the support platform 11. After installation, the cylinder 9 retracts the output end to pull down the pressing plate 8, so that the pressing plate 8 presses the steel pipe tightly to achieve a fixing effect.

[0020] A rotating plate 5 is provided on the side of the mounting frame 4 away from the support platform 11. Fixed rings 15 are provided on both sides of the bottom of the rotating plate 5. The fixed rings 15 are fixedly mounted on the workbench 1. Fixed rods are installed at both ends of the bottom of the rotating plate 5. The fixed rods and the fixed rings 15 are connected by damping bearings. A dust suction port 6 is provided on the outer wall of the rotating plate 5. The axis of the dust suction port 6 is colinear with the axis of the threaded rod 3. In the initial state, the outer wall of the rotating plate 5 fits the table surface of the workbench 1. After the steel pipe is fixed by the pressing plate 8, the operator flips the rotating plate 5 upward so that the outer wall of the rotating plate 5 abuts against the end of the steel pipe. The dust suction port 6 is externally connected to an industrial vacuum cleaner to absorb impurities splashed when the grinding wheel 7 grinds the steel pipe.

[0021] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
