Description
Technical Field
[0001] The invention relates to the technical field of crane manufacturing equipment, in particular to a metal pipe inner wall grinding device for crane production. Background Art
[0002] Cranes are mechanical equipment used to lift and transport heavy objects, and they play an important role in industrial production. The production process of cranes includes material preparation, processing, welding, spraying and assembly. In order to ensure the corrosion resistance of metal pipes and enhance the adhesion of paint, all metal pipes need to be pre-treated by grinding and polishing before cutting. Only after the rust removal level reaches the standard can double-sided spray primer be applied for protection.
[0003] Deficiencies of existing technology: At present, when grinding the inner wall of metal pipe fittings, a long rod is often used to drive the grinding wheel to rotate at high speed to achieve polishing. However, since the grinding wheel can only rotate in one direction, the polishing effect of some corners of the inner wall is poor, and the grinding effect is not good. In addition, the length of the long rod is fixed, while the length of the metal pipe fittings is different, and it cannot adapt to metal pipe fittings of different sizes, which will result in other places on the inner wall of the pipe fitting not being processed and can only be polished manually later, which is time-consuming and labor-intensive. Summary of the invention
[0004] The purpose of the present invention is to provide a metal pipe inner wall grinding device for crane production to solve the problems raised in the above background technology.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The inner wall grinding device of a metal pipe for crane production is provided with a first motor, a disc, a rocker and a workbench to make a grinding wheel reciprocate up and down. First, the metal pipe is placed on the storage table and fixed, then the first motor is started to drive the disc to rotate. When the disc rotates, the rocker drives the workbench to reciprocate up and down. The second motor is started to drive the driving gear to rotate. At the same time, two bevel gears located on the upper and lower sides of the driving gear rotate, driving the grinding wheel to grind the metal pipe up and down. Since the two bevel gears rotate in opposite directions, the inner wall of the metal pipe can be more fully polished, and the polishing effect is good. The device for grinding the inner wall of metal pipes used in crane production adjusts the stroke of a workbench by setting a lead screw and a ball nut. When it is necessary to grind metal pipes of different heights, the lead screw is rotated to move the ball nut, thereby adjusting the position of the rocker on the disc and changing the distance the workbench moves up and down. The device can adapt to metal pipes of different sizes and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

The grinding mechanism 3 includes a second motor 31 and two bevel gears 32. The second motor 31 is arranged at the upper end of the workbench 132, and a driving gear 311 is arranged on the output shaft of the second motor 31. Two bevel gears 32 are arranged at the upper end of the workbench 132, and both of the two bevel gears 32 are meshed and connected with the driving gear 311. The lower ends of the two bevel gears 32 are provided with grinding wheels 321. First, the metal pipe is placed on the storage table 12 and fixed, and then the first motor 21 is started to drive the disc 211 to rotate. While the disc 211 rotates, the rocker 214 drives the workbench 132 to reciprocate up and down. The second motor 31 is started to drive the driving gear 311 to rotate. At the same time, the two bevel gears 32 located on the upper and lower sides of the driving gear 311 rotate, driving the grinding wheel 321 to grind the metal pipe up and down. Since the two bevel gears 32 rotate in opposite directions, the inner wall of the metal pipe can be polished more fully and the polishing effect is good.

[0026] The working principle of the present invention is as follows: When the inner wall grinding device of a metal pipe for crane production of the present embodiment is used, the metal pipe is first placed on the storage table 12 and fixed, and then the first motor 21 is started to drive the disc 211 to rotate. While the disc 211 rotates, the rocker 214 drives the workbench 132 to reciprocate up and down, and the second motor 31 is started to drive the driving gear 311 to rotate. At the same time, the two bevel gears 32 located on the upper and lower sides of the driving gear 311 rotate, and drive the grinding wheel 321 to grind the metal pipe up and down. Since the two bevel gears 32 rotate in opposite directions, the inner wall of the metal pipe can be more fully polished and the grinding effect is good. When it is necessary to grind metal pipes of different heights, the screw rod 212 is rotated to move the ball nut 213, thereby adjusting the position of the rocker 214 on the disc 211, and changing the distance that the workbench 132 moves up and down, which can adapt to metal pipes of different sizes and has a wide range of applications. In addition, the grinding wheel 321 is connected to the connecting rod 322 by bolts, which is convenient for replacing grinding wheels 321 of different sizes to adapt to different workpieces.
