Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic steel pipe production, in particular to a high-efficiency hydraulic steel pipe grinding device. Background Art

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipe fittings. Construction projects, power plants, chemical plants, etc. often use such pipes. Therefore, hydraulic steel pipes have to be used with high precision. Therefore, the hydraulic steel pipe models need to be ground and polished during the production process to improve the quality of the hydraulic cylinder.

[0003] Most of the existing hydraulic steel pipe grinding devices clamp the steel pipe and drive the steel pipe to rotate, and then grind the steel pipe through the grinding device. However, most of the existing grinding devices are fixed or parallel moving, so they can only polish and grind steel pipes of the same diameter, which greatly reduces the scope of application of the device.

[0004] For example, the existing Chinese patent publication number is: CN208681174U, a high-efficiency hydraulic steel pipe grinding device, including a base, a first hydraulic rod is fixedly connected to the right side of the top of the base, a first motor is fixedly connected to the left side of the first hydraulic rod, a sleeve is fixedly connected to the left side of the first motor, threaded holes are provided on the top, bottom, front and back of the sleeve, and threaded rods are penetrated through the top, bottom, front and back of the sleeve.

[0005] It can be seen that the patent documents cited above also have the same problem. Although the above-mentioned device can realize the grinding head rotating to grind the steel pipe and can also move the grinding head laterally, which greatly improves the grinding efficiency of the steel pipe, improves the work efficiency of the operator, and is convenient for people to use, but in actual use, the longitudinal position of the grinding device cannot be adjusted. Therefore, it can only polish steel pipes of the same diameter, which greatly reduces the scope of application of the device. Utility Model Content
