Description

Technical Field

[0001] The utility model relates to the technical field of installation industry, in particular to an electric grinding device for installing a pad of a high-precision equipment. Background Art

[0002] Whenever equipment is installed, pads are required. Pads are placed between the equipment foundation and the equipment. The functions of pads are: 1. to bear the dynamic and static loads of the equipment; 2. to bear the torque of the bolts; and 3. to adjust the level and elevation of the equipment. The size and number of pads are determined through scientific design and calculation, and determine whether the equipment operates normally. For large, high-precision equipment, the installation standard of the pads reaches 0.05m / m / piece, and the contact area between the pads reaches 0.05mm, so the feeler gauge cannot penetrate. This shows that the pad is the foundation and the key, and it is extremely important. Moreover, for equipment that vibrates particularly strongly during operation, the installation of the pads is even more important.

[0003] During the traditional installation of pads, the foundation is ground by manual planing hammer method. The disadvantages of using manual planing hammer are: 1. The blade of the planing hammer is single, and it is a point and line contact grinding method. Each grinding contact area is small and time-consuming. 2. It is difficult for staff to operate. People who have not used planing hammer grinding find it difficult to grasp the strength and direction. 3. The use of planing hammer is inefficient and the quality is difficult to guarantee.
