[0033] Two symmetrical lower surface polishing assemblies 7 are rotatably installed at the rear part of the bottom wall of the shell 1. The lower surface polishing assemblies 7 can cooperate with the polishing assembly one 6 to drive the lower surface polishing assemblies 7 to rotate during the polishing movement of the polishing assembly one 6, and then polish the upper surface and the lower surface of the gear, thereby achieving the effect of polishing multiple surfaces of the gear, and improving the polishing precision of the gear. Meanwhile, the lower surface polishing assemblies 7 can also clamp and polish gears with different thicknesses, thereby improving the versatility of the device.

[0034] A rectangular guide groove 8 is formed at the left rear edge of the upper end of the shell 1 and the right rear edge of the upper end.

[0035] In the second embodiment, the purpose of reciprocating polishing of the gear teeth is achieved.

[0036] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the polishing assembly one 6 comprises a guide rod 61 rotatably connected to the left inner surface wall middle front side and the right inner surface wall middle front side of the shell 1. The outer surface of the guide rod 61 is provided with a roller 62, the outer surface of the roller 62 is fixedly connected with a grinding wheel 63, the inner surface of the roller 62 is annularly arrayed with a plurality of ball grooves 64, the inner surface of each ball groove 64 is rotatably connected with a ball 65, the inner surface of the sliding groove 3 is slidably installed with a moving assembly 66, and each ball 65 is in close contact with the outer surface of the guide rod 61.

[0037] Further, the moving assembly 66 comprises a moving rod 661, the lower end of the moving rod 661 is slidably connected to the inner surface of the sliding groove 3, the upper right end of the moving rod 661 is fixedly connected with a rectangular plate one 662, the left end of the rectangular plate one 662 is fixedly connected with a motor 663, the output end of the motor 663 is fixedly connected with a belt pulley one 664 through a shaft coupling, the right end middle part of the grinding wheel 63 is fixedly connected with a belt pulley two 665, the outer surfaces of the belt pulley one 664 and the belt pulley two 665 are jointly wound with a belt one 667, the lower edge of the rear end of the moving rod 661 is fixedly connected with a rack 668, the output end of the hydraulic cylinder 5 is fixedly connected with the right end of the rectangular plate one 662 through a piston rod, and the left end of the moving rod 661 is slidably connected with the right end of the grinding wheel 63.

[0038] By starting the motor 663, the output end of the motor 663 drives the belt pulley I 664 fixedly connected thereto to rotate, and the outer surface of the belt pulley I 664 and the outer surface of the belt pulley II 665 are jointly wrapped with the belt I 667, so that the belt pulley II 665 is driven to rotate under the driving action of the belt I 667, and then the belt pulley II 665 drives the roller 62 fixedly connected thereto to rotate, and the roller 62 can simultaneously drive the grinding wheel 63 fixedly connected to the outer surface thereof to rotate with the center point of the guide rod 61 as the center. When the grinding wheel 63 needs to be pushed to the left during rotation, the hydraulic cylinder 5 is started. As known from the above, the output end of the hydraulic cylinder 5 extends to the inside of the housing 1 through the right end of the housing 1, and the output end of the hydraulic cylinder 5 is fixedly connected to the right end of the rectangular plate I 662 through the piston rod, and the left end of the movable rod 661 is slidably connected to the right end of the grinding wheel 63. Therefore, when the output end of the hydraulic cylinder 5 pushes the movable rod 661 to move left in the inner surface of the sliding groove 3 through the piston rod, the protruding part at the front end of the movable rod 661 can push the grinding wheel 63 to move left, and the grinding wheel 63 is slidably connected to the protruding part at the left end of the movable rod 661. Therefore, during the pushing of the grinding wheel 63, the normal rotation of the grinding wheel 63 is not affected.

The plurality of ball bearings 65 are attached to the outer surface of the guide rod 61. Therefore, the plurality of ball bearings 65 can arbitrarily roll in the direction of rotation and left movement of the roller 62 and the grinding wheel 63, thereby satisfying the rotation of the grinding wheel 63 while moving left.

[0040] During the movement of the grinding wheel 63 to the left, the gear clamped on the surface of the lower surface polishing assembly 7 can be used to polish the teeth, and during the movement of the grinding wheel 63 to the right, the teeth can be repeatedly polished, thereby improving the subsequent polishing precision. The operation steps of the grinding wheel 63 moving to the right are the same as the operation steps of moving to the left described above, and therefore this scheme will not be described in detail.

[0042] The grinding wheel 63 is composed of a large number of hard particles, usually abrasive materials. These particles are fixed on the surface of the grinding wheel 63. When the grinding wheel 63 rotates, the abrasive particles contact and cut the workpiece, and the sharp part of each abrasive particle will cut the surface of the workpiece to remove metal or other materials.

[0043] Therefore, the above-mentioned grinding wheel 63 is a conventional arrangement in the prior art, and the specific installation mode, circuit connection mode and control method thereof are all conventional designs, which will not be described in detail.

[0050] Further, the outer surfaces of the two upper surface polishing tables 7110 and the two bottom wall polishing tables 79 are fixedly connected with sandpaper.

[0051] First, the shaft holes in the middle positions of the two gears are inserted into the outer surfaces of the two bolt columns 78 respectively, then the two gears will slide down along the outer surfaces of the same side bolt column 78 to the upper end of the same side bottom wall polishing table 79, and then by holding the two handles 7015, the two limiting plate two 7014 are aligned with the two sides of the rectangular guide groove 8, and at the same time, the two cross rods 7011 are inserted into the same side support table 704, so as to realize the limiting and fixing of the rectangular plate two 7013.

[0052] As known from the above, the two gear two 73 are matched with the rack 668, so when the rack 668 is driven to move left by the moving rod 661, when the rack 668 passes through the two gear two 73, the two gear two 73 are engaged, and then the two gear two 73 are driven to rotate, and when the two gear two 73 rotate, as known from the above, the gear two 73 and the gear three 74 are engaged with the gear one 72, so the gear one 72 drives the transmission cylinder 71 to rotate with the gear three 74.

[0053] The transmission direction of gear three 74 is opposite to the rotation direction of gear one 72, and then when the transmission cylinder 71 rotates, the bottom wall polishing table 79 fixedly connected to the upper end thereof can also rotate, and when the gear three 74 rotates, it is known from the above that the bolt column 78 is located inside the transmission cylinder 71, the bolt column 78 and the gear three 74 are fixedly connected with the connecting columns 75, the two connecting columns 75 penetrate through the bottom wall of the shell 1 and extend to the outside, the outer surfaces of the two connecting columns 75 are fixedly connected with the belt pulleys three 76, and the outer surfaces of the two belt pulleys three 76 are commonly wound with the belt two 77, so that the two connecting columns 75 can be driven to rotate under the transmission action of the belt two 77, and one of the connecting columns 75 is fixedly connected with the bolt column 78, so that the bolt column 78 can be driven to rotate, so as to drive the gear inserted on the surface of the bolt column 78 to rotate, and the rotation direction of the gear is opposite to that of the bottom wall polishing table 79;

[0054] When the transmission cylinder 71 rotates, the outer surfaces thereof and the outer surfaces of the rotating rods 703 are fixedly connected with the belt pulleys four 705, and the two belt pulleys four 705 are transmissionally connected through the belt three 706, so that the rotating rods 703 can be driven to rotate when the transmission cylinder 71 rotates, and the limiting plates one 700 and the supporting tables 704 play a limiting and guiding role;

[0055] When the rotating rods 703 rotate, the cross rods 7011 inserted in the inner cavities of the cross grooves 707 can also rotate, and it is known from the above that the outer surfaces of the cylindrical two 7018 and the cylindrical one 7012 are fixedly connected with the belt pulleys five 7019, and the outer surfaces of the two belt pulleys five 7019 are commonly wound with the belt four 7010, so that the cylindrical two 7018 can be driven to rotate under the action of the two belt pulleys five 7019 and the belt four 7010 wound on the outer surfaces of the two belt pulleys five 7019 when the cylindrical one 7012 is driven to rotate by the cross rods 7011;

[0057] In order to clamp gears of different thicknesses, when the upper surface grinding table 7110 lower end contacts the upper surface of the gear, the upper surface grinding table 7110 drives the connecting column 7017 to slide upwards in the sliding hole 7016, and the cross rod 7011 can simultaneously extrude the spring 7112, so as to realize the effect of clamping gears of different thicknesses, and the circular plate 7113 can prevent the connecting column 7017 from sliding out of the inner cavity of the sliding hole 7016, and when the gear needs to be taken out subsequently, only the handle 7015 needs to be held and lifted upwards, so that the upper surface grinding assembly 701 can be taken out as a whole, and then the gear after grinding is taken out.

[0058] The fixed sandpaper in the above is a conventional setting in the prior art, and in the present scheme, only the effect of grinding the upper surface and the lower surface of the gear needs to be met, so the present scheme will not be described in detail.
