The lower surface grinding assembly 7 can cooperate with the grinding assembly 6, so that during the grinding movement of the grinding assembly 6, the lower surface grinding assembly 7 is driven to rotate, and then the lower surface grinding assembly 7 grinds the upper and lower surfaces of the gear, thereby achieving the effect of grinding multiple surfaces of the gear, thereby improving the subsequent grinding accuracy of the gear. At the same time, the lower surface grinding assembly 7 can also clamp and grind gears of different thicknesses according to the different thicknesses of the gears, thereby improving the versatility of the device;

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

[0035] Embodiment 2 is to achieve the purpose of reciprocating grinding of the teeth of the gear.

[0036] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The grinding component 6 includes a guide rod 61 which is rotatably connected to the front middle part of the left side wall of the inner surface of the shell 1 and the front middle part of the right side wall of the inner surface. A roller 62 is provided on the outer surface of the guide rod 61. A grinding wheel 63 is fixedly connected to the outer surface of the roller 62. A plurality of ball grooves 64 are provided in an annular array on the inner surface of the roller 62. Balls 65 are rotatably connected to the inner surfaces of the ball grooves 64. A moving component 66 is slidably installed on the inner surface of the slide groove 3. The plurality of balls 65 are in contact with the outer surface of the guide rod 61.

[0037] Furthermore, the moving component 66 includes a moving rod 661, the lower end of which is slidably connected to the inner surface of the slide groove 3, a rectangular plate 662 is fixedly connected to the right side of the upper end of the moving rod 661, a motor 663 is fixedly connected to the left end of the rectangular plate 662, the output end of the motor 663 is fixedly connected to a pulley 664 through a coupling, a pulley 2 665 is fixedly connected to the middle of the right end of the grinding wheel 63, a belt 667 is wound together on the outer surfaces of the pulley 1 664 and the pulley 2 665, a rack 668 is fixedly connected to the lower edge of the rear end of the moving rod 661, the output end of the hydraulic cylinder 5 is fixedly connected to the right end of the rectangular plate 662 through a piston rod, and the upper protruding part of the left end of the moving rod 661 is slidably connected to the right end of the grinding wheel 63.

[0038] By starting the motor 663, the output end of the motor 663 drives the pulley 1 664 fixedly connected thereto to rotate through the coupling, and the outer surface of the pulley 1 664 and the outer surface of the pulley 2 665 are wound with a belt 1 667. Therefore, under the transmission action of the belt 1 667, the pulley 2 665 is driven to rotate, and then the pulley 2 665 drives the roller 62 fixedly connected thereto to rotate, and the roller 62 can simultaneously drive the grinding wheel 63 fixedly connected to its outer surface to rotate with the center point of the guide rod 61 as the center of the circle. When the grinding wheel 63 needs to be pushed to the left during its rotation, it only needs to start the hydraulic The hydraulic cylinder 5 is a hydraulic cylinder having a plurality of movable rods, each of which is provided with a plurality of movable rods, and each of which is provided with a plurality of movable rods. The movable rods 661 are provided with ...

[0039] When the grinding wheel 63 moves to the left, in order to allow the grinding wheel 63 to move to the left normally during the rotation, a plurality of ball grooves 64 are provided in an annular array on the inner surface of the drum 62, and balls 65 are rotatably connected to the inner surfaces of the plurality of ball grooves 64, and the plurality of balls 65 are all attached to the outer surface of the guide rod 61, so that the plurality of balls 65 can roll arbitrarily following the rotation and leftward movement of the drum 62 and the grinding wheel 63, thereby satisfying the grinding wheel 63 to move to the left and rotate at the same time;

[0040] While the grinding wheel 63 moves to the left, it can pass through the gear clamped on the surface of the lower surface grinding assembly 7 and then grind the teeth. When the grinding wheel 63 moves to the right, the teeth can be repeatedly grinded again, thereby improving the subsequent grinding accuracy. The operating steps for moving the grinding wheel 63 to the right are the same as the above-mentioned operating steps for moving to the left, so this solution will not be described in detail.

[0041] The grinding wheel 63 mentioned above is a conventional design in the prior art, and its specific principle is as follows:

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

[0043] Therefore, the grinding wheel 63 mentioned above is a conventional setting in the prior art, and its specific installation method, circuit connection method and control method are all conventional designs, which will not be elaborated in detail in this solution.

[0044] Embodiment 3: This embodiment is based on Embodiment 2 and is for the purpose of grinding the upper and lower surfaces of the gear.

[0045] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 The lower surface grinding assembly 7 includes a transmission cylinder 71 rotatably connected to the left rear side of the bottom wall of the housing 1, a gear 1 72 is fixedly connected to the lower part of the outer surface of the transmission cylinder 71, a gear 2 73 is provided on the right front side of the gear 1 72, a gear 3 74 is provided on the right rear side of the gear 1 72, the lower ends of the gear 2 73 and the gear 3 74 are both rotatably connected to the bottom wall of the housing 1, the gear 2 73 and the gear 3 74 are both meshed with the gear 1 72, the bottom wall of the housing 1 is rotatably connected to a bolt 78, the bolt 78 is located on the inner side of the transmission cylinder 71, and the bolt 78 and the lower ends of the gear 3 74 are fixed A connecting column 75 is fixedly connected, and the two connecting columns 75 both penetrate the bottom wall of the outer shell 1 and extend to the outside. The outer surfaces of the two connecting columns 75 are fixedly connected with pulleys three 76, and the outer surfaces of the two pulleys three 76 are commonly wound with belts two 77. The upper end of the transmission cylinder 71 is fixedly connected with a bottom wall grinding table 79, and a circular hole 791 that penetrates the lower end of the bottom wall grinding table 79 is opened in the middle of the upper end of the bottom wall grinding table 79. A limited transmission component 70 is rotatably installed on the outer surface of the transmission cylinder 71, and an upper surface grinding component 701 is slidably installed on the outer surface of the limited transmission component 70.

[0046] Furthermore, the two gears 73 cooperate with the rack 668.

[0047] Furthermore, the limiting transmission assembly 70 includes a limiting plate 700 rotatably connected to the upper outer surface of the transmission cylinder 71, a limiting hole 702 penetrating the lower end of the limiting plate 700 is opened on the left side of the upper end of the limiting plate 700, a rotating rod 703 is rotatably connected to the inner surface of the limiting hole 702, a support platform 704 is fixedly connected to the middle part of the lower end of the limiting plate 700, the lower end of the support platform 704 is fixedly connected to the bottom wall of the outer shell 1, the rotating rod 703 and the outer surface of the transmission cylinder 71 are fixedly connected with pulley four 705, the two pulleys four 705 are both located on the lower side of the limiting plate 700, the outer surfaces of the two pulleys four 705 are commonly wrapped with belt three 706, and a cross groove 707 is opened at the upper end of the rotating rod 703.

[0048] Furthermore, the upper surface grinding assembly 701 includes a cross rod 7011, the cross rod 7011 is slidably connected to the inner surface of the cross groove 707, the upper end of the cross rod 7011 is fixedly connected to a cylinder 1 7012, the upper end of the cylinder 1 7012 is rotatably connected to a rectangular plate 2 7013, the left end of the rectangular plate 2 7013 is fixedly connected to a limiting plate 2 7014, the middle part of the upper end of the rectangular plate 2 7013 is fixedly connected to a handle 7015, a sliding hole 7016 is opened on the right side of the middle part of the upper end of the rectangular plate 2 7013, and the inner surface of the sliding hole 7016 is slidably connected to the inner surface of the sliding hole 7016. A connecting column 7017 is connected, and the outer surface of the connecting column 7017 is slidably connected to the cylinder 2 7018, and the outer surfaces of the cylinder 2 7018 and the cylinder 1 7012 are fixedly connected to the pulley 5 7019, and the outer surfaces of the two pulleys 5 7019 are commonly wound with the belt 4 7010, and the lower end of the connecting column 7017 is fixedly connected to the upper surface grinding table 7110, and the upper surface grinding table 7110 and the end close to the cylinder 2 7018 are commonly fixedly connected to the spring 7112, and the upper end of the sliding hole 7016 is fixedly connected to the circular plate 7113.

[0049] Furthermore, the two second limiting plates 7014 are respectively slidably connected to the inner surface of the rectangular guide groove 8 on the same side.

[0050] Furthermore, sandpaper is fixedly connected to the outer surfaces of the two upper surface grinding tables 7110 and the two bottom wall grinding tables 79 .

[0051] First, insert the shaft holes in the middle of the two gears into the outer surfaces of the two bolts 78 respectively, and then the two gears will slide along the outer surfaces of the bolts 78 on the same side to the upper end of the bottom wall grinding table 79 on the same side, and then hold the two handles 7015 to align the two limit plates 7014 with the rectangular guide grooves 8 on both sides, and at the same time, insert the two cross rods 7011 into the support platform 704 on the same side, so as to achieve the limit fixation of the rectangular plate 7013;

[0052] As can be seen from the above, both gears 73 are engaged with the rack 668. Therefore, when the moving rod 661 drives the rack 668 to move to the left, when the rack 668 passes through the two gears 73, it meshes with the two gears 73, and then drives the two gears 73 to rotate. When the two gears 73 rotate, as can be seen from the above, both gears 73 and gear 3 74 are meshed with gear 1 72. Therefore, gear 1 72 drives the transmission cylinder 71 and gear 3 74 to rotate.

[0053] The transmission direction of gear three 74 is opposite to the rotation direction of gear one 72. Subsequently, when the transmission cylinder 71 rotates, it can simultaneously drive the bottom wall grinding table 79 fixedly connected to its upper end to rotate. When the gear three 74 rotates, it can be known from the above that the bolt post 78 is located on the inner side of the transmission cylinder 71, and the bolt post 78 and the lower end of the gear three 74 are fixedly connected to the connecting post 75. The two connecting posts 75 both penetrate the bottom wall of the shell 1 and extend to the outside. The outer surfaces of the two connecting posts 75 are fixedly connected to the pulley three 76. The outer surfaces of the two pulley three 76 are jointly wrapped with the belt two 77. Therefore, under the transmission action of the belt two 77, the two connecting posts 75 can be driven to rotate at the same time, and one of the connecting posts 75 is fixedly connected to the bolt post 78, so it can drive the bolt post 78 to rotate, so that the bolt post 78 drives the gear inserted on its surface to rotate, and the direction of rotation of the gear is opposite to the direction of rotation of the bottom wall grinding table 79.

[0054] When the transmission cylinder 71 rotates, since the outer surface of the transmission cylinder 71 and the outer surface of the rotating rod 703 are fixedly connected with the pulley 4 705, and the two pulleys 4 705 are connected by the belt 3 706, when the transmission cylinder 71 rotates, the rotating rod 703 can be driven to rotate at the same time, and the limiting plate 1 700 and the support platform 704 play the role of limiting guide;

[0055] When the rotating rod 703 rotates, the cross rod 7011 inserted into the inner cavity of the cross groove 707 can be driven to rotate at the same time. As can be seen from the above, the outer surfaces of the second cylinder 7018 and the first cylinder 7012 are fixedly connected with the fifth pulley 7019, and the outer surfaces of the two fifth pulleys 7019 are commonly wound with the fourth belt 7010. Therefore, when the cross rod 7011 drives the first cylinder 7012 to rotate, under the action of the two fifth pulleys 7019 and the fourth belt 7010 wound on the outer surfaces of the two fifth pulleys 7019, the second cylinder 7018 can be driven to rotate at the same time.

[0056] When the second cylinder 7018 rotates, the connecting column 7017 slidably connected to its inner surface also rotates accordingly, and the connecting column 7017 is only set to slide up and down on the inner surface of the second cylinder 7018, so that the second cylinder 7018 can drive the connecting column 7017 to rotate, and the connecting column 7017 can drive the upper surface grinding table 7110 fixedly connected to its lower end to rotate at the same time. From the above, it can be seen that the outer surfaces of the two upper surface grinding tables 7110 and the two bottom wall grinding tables 79 are fixedly connected with sandpaper, and the upper surface grinding tables 7110 and the bottom wall grinding tables 79 rotate in the same direction, but opposite to the rotation direction of the gear, thereby achieving the effect of grinding the upper and lower surfaces of the gear at the same time;

[0057] In order to clamp gears of different thicknesses, when the lower end of the upper surface grinding table 7110 contacts the upper surface of the gear, the upper surface grinding table 7110 will drive the connecting column 7017 to slide upward in the sliding hole 7016, and the cross rod 7011 can squeeze the spring 7112 at the same time, thereby achieving 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. When the gear needs to be taken out later, it is only necessary to hold the handle 7015 and lift it upward to take out the upper surface grinding assembly 701 as a whole, and then take out the polished gear.

[0058] The fixed sandpaper mentioned above is a conventional setting in the prior art. In this solution, it only needs to meet the effect of grinding the upper and lower surfaces of the gear, so this solution will not elaborate on it in detail.

[0059] It should be noted that the specific installation method of the hydraulic cylinder 5 and the motor 663, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0060] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
