[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1, as Figure 1-2 As shown, a rotary grinding device for gear processing includes a support table 1, a grinding mechanism 4 is fixedly connected to the right side of the upper end of the support table 1, a support group 2 is fixedly connected to the middle of the upper end of the support table 1, a motor 2 6 is fixedly connected to the middle of the lower end of the support table 1, a fixing mechanism 3 is provided in the middle of the support group 2, a transmission wheel 2 5 is fixedly connected to the lower side of the fixing mechanism 3 and the output end of the motor 2 6, and the two transmission wheels 2 5 are connected by a belt.

[0032] It should be noted that the specific installation method of motor 2 6, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the fixing mechanism 3 is connected to an external air pump for use. In addition, a placing table is fixedly connected to the right side of the upper end of the support table 1, and the placing table can adjust the height according to needs, and the placing table is located directly below the right side of the fixing mechanism 3. In addition, motor 2 6 is controlled by an external control center.

[0033] First, place the gear to be polished on the right side of the fixing mechanism 3, that is, the placement table to which the support table 1 is fixedly connected, then turn on the external air pump to provide gas for the fixing mechanism 3, so that the fixing mechanism 3 clamps and fixes the gear on the right side, and then polishes the gear through the polishing mechanism 4. After polishing, start the motor 2 6 in conjunction with the transmission wheel 2 5 and the belt to drive the fixing mechanism 3 to rotate counterclockwise by 90 degrees, so that the polished gear rotates to the front side, and then place the next gear to be polished on the right side of the fixing mechanism 3 at this moment, and clamp it under the control of the external air pump and the control center, and polish it again through the polishing mechanism 4 , and so on. When the polished gear is rotated to the rear side by the fixing mechanism 3, the gear located on the rear side will be flipped 180 degrees under the cooperation of the fixing mechanism 3 and the supporting group 2, so that the unpolished end surface at the lower end is flipped to the upper end, and then rotated to the bottom of the polishing mechanism 4 by the fixing mechanism 3 to polish the unpolished end surface. After polishing, it is rotated to the front side by the fixing mechanism 3 again, and with the cooperation of the external air pump, the fixing mechanism 3 loosens the gear with polished end surfaces, so that the device has the function of polishing both end surfaces of the gear, and different types of gears can be fixed by the fixing mechanism 3, so that the application range of the device is wider.

[0034] In order to achieve the purpose of fixing different types of gears, such as Figure 3 As shown, the fixing mechanism 3 includes a rotating shaft 31, and the lower side of the outer surface of the rotating shaft 31 is rotatably connected to the inner cavity of the mounting groove opened in the middle part of the upper end of the support platform 1, and the lower end of the rotating shaft 31 is fixedly connected to the upper end of the transmission wheel 2 5 located on the front side, and the upper side of the outer surface of the rotating shaft 31 is fixedly connected with a clamping assembly 32, and the outer surface of the clamping assembly 32 is fixed with a fixing ring 2 33, and the upper side of the inner cavity of the rotating shaft 31 is fixedly connected with a gas distribution plate 34, and the input end of the gas distribution plate 34 is rotatably connected with a joint 1 35, and the upper end of the joint 1 35 is fixedly connected with a ventilation iron pipe 36, and four connecting pipe components 37 in an annular array are provided in the middle part of the outer surface of the gas distribution plate 34, and four fixing components 38 in an annular array are commonly provided between the fixing ring 2 33 and the clamping assembly 32, and the sides of the four fixing components 38 close to each other are rotatably connected to the output ends of the four connecting pipe components 37 respectively.

[0035] First of all, it should be noted that the structure of the side of the four connecting parts 37 that are away from each other is the same as that of the connector 1 35, and is composed of components such as a connector body, an airtight gasket, a snap or a locking mechanism, so that the connector 1 35 is quickly connected to the gas distribution plate 34, and the connecting part 37 is quickly connected to the fixing component 38. In addition, they can rotate with each other without air leakage. The ventilation iron pipe 36 is connected to the external air pump through a ventilation hose. When the gear is placed in the fixing component 38 on the right, the high-pressure gas generated by the air pump enters the connecting part 1 on the right through the ventilation iron pipe 36, the connector 1 35 and the gas distribution plate 34. In the tube component 37, when entering the fixing component 38, the gear is clamped and fixed by the fixing component 38, and different types of gears within a certain range can be clamped and fixed by the fixing component 38, and when the motor 26 is selected, it will drive the transmission wheel 25 fixedly connected to the motor 26 to rotate, and through the belt, the transmission wheel 25 fixedly connected to the rotating shaft 31 and the rotating shaft 31 rotate together, thereby rotating the entire fixing mechanism 3, and driving the fixing ring 2 33 to rotate together on the lower side of the middle part of the support group 2, and finally achieving the purpose of fixing different types of gears.

[0036] Further explanation, such as Figure 4 and Figure 5 As shown, the clamping assembly 32 includes a fixed circular sleeve 321, and four connecting rods 322 in an annular array are provided on the outer surface of the fixed circular sleeve 321. The ends of the four connecting rods 322 that are away from each other are fixedly connected to the inner surface of the fixed ring 2 33. Four rotating holes 323 in an annular array are provided in the middle of the inner cavity of the fixed circular sleeve 321, and the positions of the four connecting rods 322 are respectively staggered with the four rotating holes 323. Four mounting grooves 326 in an annular array are commonly provided between the upper and lower ends of the fixed circular sleeve 321. The inner cavity of the mounting groove 1 326 on the same side is provided with convex blocks 324 that are symmetrical up and down. Two springs 325 are provided at the ends of the two convex blocks 324 on the same side that are close to each other. The opposite surfaces of the two springs 325 on the same side are commonly fixedly connected to the middle of the inner cavity of the mounting groove 1 326. The inner cavity of the rotating hole 323 on the same side is communicated with the inner cavity of the mounting groove 1 326. The inner cavity of the fixed circular sleeve 321 is fixedly connected to the upper side of the outer surface of the rotating shaft 31.

[0037] In detail, the four fixing components 38 are respectively installed in the inner cavities of the four rotating holes 323, and the fixing components 38 are fixed by the convex blocks 324 which are symmetrical up and down on the same side, so that the fixing components 38 cannot rotate in the inner cavity of the rotating hole 323, and with the cooperation of the two springs 325 which are symmetrical up and down on the same side and the support group 2, the two convex blocks 324 can slide towards each other or away from each other in the inner cavity of the installation groove 1 326, so as to fix or rotate the fixing components 38, facilitate the subsequent flipping of the upper and lower ends of the gear, and cooperate with the grinding mechanism 4 to realize the grinding of the upper and lower end faces of the gear.

[0038] Further explanation, such as Figure 6 As shown, the four fixing components 38 each include a fixing sleeve 2 381, a fixing column 1 385 is fixedly connected to the side of the inner cavity of the four fixing sleeves 2 381 close to the fixing ring 2 33, a cylinder 1 386 is fixedly connected to the side of the inner cavity of the four fixing columns 1 385 away from the fixing ring 2 33, a bevel gear 384 is fixedly connected to the end of the four fixing columns 1 385 away from the cylinder 1 386, an air pipe 1 382 is provided in the middle of the inner cavity of the four fixing sleeves 2 381, an air pipe 2 383 is provided in the middle of the outer surface of the four fixing sleeves 2 381 close to the air pipe 1 382, ​​and the four fixing sleeves 381 are fixedly connected to the side of the inner cavity of the four fixing sleeves 381 close to the air pipe 1 382. A clamping group 389 is fixedly connected to one side of the middle part of the inner cavity of sleeve 2 381 away from fixed ring 2 33, and the clamping group 389 on the same side is connected to cylinder 1 386 through air pipe 1 382 and air pipe 2 383 respectively, and a clamping block 388 is fixedly connected to the output end of cylinder 1 386 on the same side and the side of the clamping group 389 close to cylinder 1 386, and a sliding rod 1 387 is fixedly connected to the output ends of the four cylinders 1 386, and the outer surfaces of the four sliding rods 1 387 are respectively slidably connected to the inner cavities of four fixed columns 1 385, and the outer surfaces of the four fixed columns 1 385 are rotatably connected to the middle part of the inner surface of fixed ring 2 33.

[0039] It should be noted that the specific installation method and control method of cylinder 386 in the present invention are conventional designs and are conventional design means for designers.

[0040] In detail, when the gear is placed between the two clamping blocks 388, the high-pressure gas generated by the air pump eventually enters the clamping group 389 through the connecting pipe component 37, and enters the cylinder 1 386 through the air pipe 2 383, so that the cylinder 1 386 and the clamping group 389 drive the two clamping blocks 388 to move closer to each other to clamp the gear, and the gear diameter can be clamped within the distance range of the two clamping blocks 388. When the gear needs to be rotated after grinding, the bevel gear 384 drives the fixing column 1 385 to rotate the entire fixing assembly 38 through the coordinated use of the support group 2 and the clamping assembly 32, thereby realizing the flipping of the gear.

[0041] Further explanation, such as Figure 7The four clamping groups 389 shown in the figure all include a second fixing column 3893, and the inner cavities of the four second fixing columns 3893 are fixedly connected to the second connector 3896 on the sides close to each other, and the output ends of the four second connectors 3896 are fixedly connected to the electric control gas valve 3895, and the input ends of the four second connectors 3896 are respectively rotatably connected to the output ends of the four connecting pipe components 37, and the sides of the four second fixing columns 3893 away from each other are fixedly connected to the second cylinder 3891, and the output ends of the four second cylinders 3891 are respectively fixedly connected to the four clamping blocks 388 away from the first cylinder 386, and the output ends of the four second cylinders 3891 are fixedly connected to the second slide rod 3892 The outer surfaces of the four sliding rods 3892 are respectively slidably connected with the inner cavities of the four fixed columns 3893, and the two air inlets of the cylinder 2 3891 and the cylinder 1 386 on the same side are respectively connected through the air pipe 1 382 and the air pipe 2 383, and the input ends of the air pipe 1 382 and the air pipe 2 383 are fixedly connected with the output end of the electric control air valve 3895. The middle part of the outer surface of the four fixed columns 3893 is provided with a vertically symmetrical groove 3894, and the outer surfaces of the four fixed columns 3893 are respectively rotatably connected with the inner cavities of the four rotating holes 323, and the inner cavities of the two grooves 3894 on the same side are respectively slidably connected with the sides of the two convex blocks 324 close to each other.

[0042] It should be noted that the specific installation method of the electric-controlled gas valve 3895 and the second cylinder 3891, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the electric-controlled gas valve 3895 is controlled by an external control center. The second cylinder 3891 is the same as the first cylinder 386. The two are connected by the air pipe 1 382 and the air pipe 2 383 respectively. The connecting part 37 and the joint 2 3896 can be quickly connected and can be rotated.

[0043] In detail, when high-pressure gas enters into air pipe 2 383 through connecting component 37, connector 2 3896 and electric-controlled air valve 3895, the gas will simultaneously enter into the side where cylinder 2 3891 and cylinder 1 386 are away from each other, so that the output ends of cylinder 2 3891 and cylinder 1 386 drive the clamping block 388 to move closer to each other, thereby clamping and fixing the gear. Slide bar 2 3892 has the same function as slide bar 1 387, which serves as an auxiliary support to increase the clamping stability. When the gas enters into air pipe 1 382, ​​the output ends of cylinder 2 3891 and cylinder 1 386 drive the clamping block 388 to move away from each other, thereby loosening the clamping of the gear. The slot 3894 is used in conjunction with the convex block 324 to limit the rotation or fixation of the fixing column 2 3893.

[0044] In order to cooperate with the fixing mechanism 3 to achieve the purpose of turning over the upper and lower end surfaces of the gear, as shown in FIG. Figure 8As shown, the support group 2 includes a fixed ring 21, the upper and lower ends of the fixed ring 21 are fixedly connected with a splint component 22, and the two splint components 22 are symmetrically arranged, a rotation groove 23 is opened on the lower side of the inner cavity of the fixed ring 21, a fan-shaped tooth plate 25 is fixedly connected to the rear part of the lower side of the inner cavity of the fixed ring 21, and arc grooves 24 are opened on the rear sides of the opposite surfaces of the two splint components 22. The inner cavity of the rotation groove 23 is rotatably connected to the lower side of the outer surface of the fixed ring 2 33, the lower end of the fixed ring 21 is fixedly connected to the middle part of the upper end of the support platform 1, and the middle parts of the opposite surfaces of the two splint components 22 are respectively fitted with the upper and lower ends of the fixed circular sleeve 1 321.

[0045] First, the upper and lower end surfaces of the fixed circular sleeve 321 are fitted by two upper and lower symmetrical clamping plate parts 22, but the rotation of the fixed circular sleeve 321 is not affected, so that the clamping plate parts 22 press the convex blocks 324 on the upper and lower sides, and the convex blocks 324 compress the spring 325, so that the convex blocks 324 are stuck in the inner cavity of the card slot 3894, so that the clamping group 389 cannot rotate, thereby fixing the fixing component 38. When the fixed circular sleeve 321 rotates to the arc groove 24, under the elastic force of the spring 325, the convex blocks 324 that are symmetrical in upper and lower directions move away from each other and disengage from the inner cavity of the card slot 3894, and at the same time, the cone The gear 384 begins to mesh with the upper side of the outer surface of the sector tooth plate 25 and rotates, so that the bevel gear 384 drives the fixing column 1 385 to rotate in the inner cavity of the circular groove opened in the middle part of the inner surface of the fixing ring 2 33, and the fixing column 2 3893 rotates in the inner cavity of the rotating hole 323. When the bevel gear 384 rotates from the upper side of the outer surface of the sector tooth plate 25 and disengages from the right rear side, the fixing assembly 38 drives the gear to flip exactly one hundred and eighty degrees, and the splint component 22 starts to compress the convex block 324 again, and gets stuck in the inner cavity of the slot 3894, and fixes the fixing assembly 38 again, and finally realizes the flipping of the gear end face.
