[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figs. 1-3 In this embodiment: a polishing device for processing generator housings includes a polishing table 1, a lifting device 4 on the upper surface of the polishing table 1, a placement plate 11 on the lifting device 4, and a polishing device 2 on the placement plate 11. The polishing device 2 is used to polish the generator housing. The polishing device 2 includes a rotary motor 21, which is fixedly connected to the placement plate 11. The main shaft of the rotary motor 21 passes through the placement plate 11, and the main shaft of the rotary motor 21 is fixedly connected to an adjustable polishing head 3. The adjustable polishing head 3 includes a circular block 31, which is fixedly connected to the main shaft of the rotary motor 21. The lower surface of the circular block 31 is provided with multiple circular slots. Circular rods 32 are slidably connected inside the circular slots. A fixing rod 33 is fixedly connected to the lower surface of the circular block 31. Polishing discs 34 are fixedly connected to the lower surfaces of the circular rods 32 and the fixing rods 33. A first spring 35 is fixedly connected to the upper surface of the circular rods 32 and the circular slot. All the circular rods 32 are arranged in a circular array. A control ring 36 is fixedly connected to the outer side of all the circular rods 32. The side wall of the circular block 31 is provided with multiple insertion holes. Insert rods 37 are slidably connected to the side wall of the control ring 36. Insert rods 37 pass through the control ring 36. A limiting block 38 is fixedly connected to one end of the insert rod 37. A second spring 39 is fixedly connected between the limiting block 38 and the control ring 36.

[0019] The generator housing is placed on the polishing table 1. Then, the lifting device 4 lowers the polishing device 2 so that it contacts the generator housing. The rotary motor 21 then rotates the adjustable polishing head 3, causing the circular block 31 to rotate. This rotation causes the polishing disc 34 on the lower surface of the circular rod 32 and the fixed rod 33 to rotate, polishing the larger areas of the generator housing surface. When it is necessary to polish the grooves on the generator housing, the control ring 36 is pushed upward. The control ring 36 moves all the circular rods 32 upward, causing the fixed rod 33 to protrude and polish the grooves on the generator housing surface. By setting the adjustable polishing head 3, the device can polish both large areas and small grooves. The operation is simple and convenient, and no worker disassembly is required.

[0020] After the control ring 36 moves all the circular rods 32 upward, the control ring 36 is fixed by pushing the insertion rod 37 into the insertion hole. By inserting into different insertion holes, the degree of protrusion of the fixing rod 33 can be controlled to adapt to grooves of different depths, making the application more flexible.

[0021] The lifting device 4 includes a vertical plate 41, a vertical groove on one side of the vertical plate 41, a sliding block 42 slidably connected in the vertical groove, a placement plate 11 fixedly connected to the sliding block 42, an electric push rod 43 fixedly connected to one side of the vertical plate 41, the telescopic rod of the electric push rod 43 fixedly connected to the placement plate 11, two transverse grooves on the upper surface of the polishing table 1, a slider 44 slidably connected in the transverse grooves, a crossbar 45 fixedly connected to the upper surface of the slider 44, an extrusion block 46 fixedly connected to one end of the two crossbars 45, and cylinders 47 fixedly connected to both sides of the polishing table 1, the telescopic rods of the two cylinders 47 being fixedly connected to the sliders 44 respectively.

[0022] When the lifting device 4 drives the polishing device 4 to rise and fall, the electric push rod 43 pushes the sliding block 42 to slide, making the polishing device 4 rise and fall more convenient. Before this, the cylinders 47 on both sides push the slider 44 to move, so that the two extrusion blocks 46 press and fix the generator housing, so as to avoid the generator housing from shifting during polishing, which would result in poor polishing effect.

[0023] The working principle and usage process of this utility model are as follows: The generator housing is placed on the polishing table 1. The cylinders 47 on both sides push the slider 44 to move, so that the two extrusion blocks 46 press and fix the generator housing. The electric push rod 43 pushes the sliding block 42 to slide. The rotary motor 21 drives the adjustable polishing head 3 to rotate. The circular block 31 rotates, which drives the polishing disc 34 on the lower surface of the circular rod 32 and the fixed rod 33 to rotate, polishing the larger area of ​​the generator housing surface. The control ring 36 drives all the circular rods 32 to move upward, so that the fixed rod 33 protrudes, polishing the grooves on the surface of the generator housing.
