[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example:
[0026] See also Figure 1-Figure 3The utility model provides a polishing and grinding device for coupling production, including a bending splint 1, which is an equilateral structure. An arc handle 2 is provided at the bending angle position of the bending splint 1, and the arc handle 2 is on the inner side of the bending splint 1. A motor 3 is fixedly installed at the outer positions of both ends of the bending splint 1, and a gear 4 is movably installed at the end and the bending angle position of the bending splint 1. The rotating shaft of the motor 3 is fixedly connected to the shaft rod of the gear 4, and a pressing shaft 5 is movably installed on the outer side of the gear 4. An engaging rubber belt 6 is meshingly installed on the outer side of the gear 4, and a grinding belt 7 is fixedly installed on the outer side of the meshing rubber belt 6, and the pressing shaft 5 is pressed on the grinding belt 7.
[0027] Specifically, the included angle of the bending clamp plate 1 is between 40 degrees and 60 degrees, and the meshing rubber belt 6 and the grinding belt 7 cannot be touched by hands when grinding the concave part.
[0028] Specifically, Figure 3 As shown, a distance is maintained between the arc handle 2 and the gear 4 and the meshing rubber belt 6 to prevent the arc handle 2 and the hand from affecting the rotation of the gear 4 and the meshing rubber belt 6.
[0029] Specifically, the grinding belt 7 is glued and fixed on the meshing rubber belt 6, which is low in cost and convenient.
[0030] Specifically, Figure 3 As shown, there are two pressing shafts 5 at the end of the bending splint 1, and only one pressing shaft 5 at the bending angle of the bending splint 1. Under the premise of solving the anti-slip problem, the number of pressing shafts 5 is reduced to the greatest extent to reduce the cost.
[0031] Working principle:
[0032] When in use, hold the arc handle 2, start the motor 3, rotate the gear 4, rotate the meshing rubber belt 6, rotate the meshing rubber belt 6 and the grinding belt 7 at the same time, and then press the grinding belt 7 on the surface of the coupling for grinding. The pressing shaft 5 presses the meshing rubber belt 6 and the grinding belt 7 to prevent the meshing rubber belt 6 and the grinding belt 7 from loosening and falling off the gear 4 when the meshing rubber belt 6 and the grinding belt 7 are long.
