Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, and in particular to a polishing machine with a debris splashing protection structure. Background Art

[0002] All high-temperature and high-pressure pipelines must be degreased and rusted before the pipe ends are welded. Before the appearance of pipe end grinders, these tasks were completed with common tools such as angle grinders and electric grinders. Due to the influence of the working environment and working area, the progress was slow and the labor intensity was high. After the appearance of pipe end grinders, this working situation was greatly improved, which not only accelerated the work speed, but also greatly reduced the burden on the operator.

[0003] After searching, the Chinese patent announcement number is CN218696947U, which discloses a pipe mouth polishing machine. In this patent, a baffle is set to block the splashing high-temperature debris and make it enter the leakage trough to avoid polluting the environment and scalding workers. When the diameter of the pipe is too large, the angle of the baffle can be adjusted by the servo motor to drive the worm, and the pipe can still be set between the two sets of baffles, thereby increasing the application range of the baffle;

[0004] However, in the above device, the baffles arranged on the left and right can only prevent the debris generated during the left and right splashing grinding process, causing some debris to splash out from the top direction of the left and right baffles, thereby causing damage to nearby workers. At the same time, it is impossible to effectively fix pipes of different shapes and sizes, resulting in different polishing effects for pipes of different sizes. Utility Model Content

Therefore, when in use, the positions of the front baffle and the rear baffle are utilized so that the debris generated during the grinding process can be completely dropped into the inner cavity of the strip groove when splashing onto the surfaces on the opposite side of the front baffle and the rear baffle. Combined with the high-temperature resistant material properties of the front baffle, the rear baffle and the arc cover, the practicability of the overall equipment is improved.

[0016] The working principle and beneficial effects of the utility model are:

[0017] The polishing machine with a debris splashing protection structure is used in conjunction with a rear baffle structure and an arc-shaped cover structure. After different buttons on the top of the switch are pressed, the winding block and the driving block are started, the grinding disc is started to rotate, and at the same time, the connecting rope contracts to drive the slider to move left, until the spring contracts to the maximum extent to the left and the slider cannot continue to move left. During the grinding process, the setting positions of the front baffle, the rear baffle and the arc-shaped cover are utilized so that the debris generated during grinding is completely splashed on the inner cavity surfaces of the front baffle, the rear baffle and the arc-shaped cover, thereby achieving the effect of effectively preventing the splashing of debris at different positions.

[0018] The polishing machine with a debris splash protection structure uses a lower pad structure and a rubber pad structure in cooperation. When working, firstly, the pipe to be polished is placed in the middle of the inner cavity of the lower pad, and the position of the pipe is continuously moved so that the left side of the pipe fits the polishing sheet. Then, different buttons on the top of the switch are pressed to contract the telescopic rod and drive the upper pad to move downward. Rubber pads of different thicknesses arranged in the inner cavities of the lower pad and the upper pad are used to increase the resistance to the rotation of the pipe, thereby effectively fixing the pipe, making it easier for the polishing sheet to effectively polish the pipe, thereby achieving the effect of effectively fixing pipes of different sizes.
