Handheld grinding device with separation grinding disc for fine repair of heat exchanger finished product

Abstract

The invention relates to a handheld grinding device with a separation grinding disc for fine repair of a heat exchanger finished product. The handheld grinding device comprises a machine body and a connecting base; an electric telescopic rod is installed at the upper left end of the machine body; a connecting rod is arranged at the end of the electric telescopic rod; an upper shielding mechanism is installed at the top end of the connecting rod; and a grip is fixed to the middle of the left end of the machine body. The handheld grinding device with the separation grinding disc for fine repairof the heat exchanger finished product has the beneficial effects that the handheld grinding device can be connected through clamping of a side box and a shielding cover, at the moment, the shieldingcover can be conveniently, firmly and stably used, internal reagents in the handheld grinding device can be conveniently leaked out and act in the shielding cover through the design of box holes, on the contrary, the shielding cover can be disassembled, at the moment, lubricating protective reagents such as dry powder or engine oil can be added into the shielding cover to protect the end part of the body, so that the device has a better environment in use and is more stable in use, and meanwhile, the positions of a connecting ruler and a connecting seat can be adjusted through the movement between the connecting ruler and the connecting seat for adaptation.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a hand-held grinding device with a separate grinding disc for the finishing of finished heat exchangers. Background technique [0002] Grinding is a kind of surface modification technology. It generally refers to a processing method that uses rough objects (sandpaper containing higher hardness particles, etc.) to change the physical properties of the material surface through friction. During the processing of devices, such as the processing of finished heat exchangers, hand-held grinding devices are generally used. [0003] The end of the existing grinding device is not properly designed, resulting in the inability to perform stretching adjustment well during use, the hand-holding process is not convenient enough, the hand-holding is not convenient enough, and the adaptability is poor, which leads to its safety and performance during processing. The comfort during processing is...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held grinding device with a separate grinding disc for the finishing of finished heat exchangers, so as to solve the problem that the end of the existing grinding device proposed in the background technology is not properly designed, resulting in that it cannot be used. Very good stretch adjustment, the hand-holding process is not convenient enough, the hand-holding is not convenient enough, the adaptability is poor, resulting in poor safety performance and processing comfort during processing, and the heat dissipation during processing is not thorough enough, The heat dissipation function is poor, and the adaptation and regulation performance of the heat dissipation part and the environment is poor
