[0029] The guide 5 is pressed against the side wall of the part for guidance, the grinding head 2 contacts the surface to be ground, and then the connecting arm 1 is held for grinding. The grinding width remains consistent, the grinding uniformity is better, the occurrence of cracks and joints is avoided, and the rework rate is reduced.
[0030] like Figure 1-Figure 4 As shown, the moving block 4 is provided with a moving groove 401 penetrating the moving block 4 in the transverse direction. The guide rail plate 3 passes through the moving groove 401 , and the moving block 4 can move along the guide rail plate 3 .
[0031] like Figure 1-Figure 4 As shown, a plurality of limiting teeth 301 are provided on the upper side of the guide rail plate 3, and the moving block 4 is movably provided with a limiting member 6, and the limiting member 6 cooperates with the limiting teeth 301 to limit. Further, the limiting member 6 includes an upper rod 601 inserted in the longitudinal direction of the moving block 4, and a limiting plate 602 provided on the upper rod 601. Both sides of the moving block 4 are respectively provided with moving holes 402 passing through it along the longitudinal direction. The moving holes 402 extend along the vertical direction. The upper rod 601 is movably provided in the moving hole 402, and the horizontal direction is perpendicular to the longitudinal direction. The moving block 4 moves along the guide rail plate 3 moves, and after adjusting to the appropriate position, the limit piece 6 and the limit tooth 301 are against each other to form a limit, and the guide piece 5 fits the side wall of the part to play a guiding role. The side wall of the part is generally perpendicular to the sealing surface. The staff holds the connecting arm 1 and starts to grind the sealing surface. In this way, the force and width of the grinding head 2 grinding the sealing surface can be kept consistent, and the grinding uniformity is good, avoiding cracks and joints. The upper rod 601 can move up and down along the moving groove 401, so that the limit piece 6 can move up and down, and the limit piece 6 moves upward. When the moving block 4 moves to the appropriate position, the limit piece 6 falls and is against the limit tooth 301 to form a limit.
