[0002] The double-sided grinding device for flywheel ring gears belongs to the technical field of grinding devices. It realizes the simultaneous grinding of the upper and lower two end faces of the flywheel ring gear through a specific mechanical structure and control system, aiming to improve the processing efficiency and grinding quality, and can effectively save processing time and labor costs.

[0003] When using the double-sided grinding device to grind the flywheel ring gear, it is necessary to first fix the fixture connected to the output end of the motor to the flywheel ring gear, so that the flywheel ring gear can rotate around the output end of the motor, so as to facilitate the two grinding discs at the top and bottom of the flywheel ring gear to grind it repeatedly. However, the types of flywheel ring gears that the fixture can fix are quite limited. When the type of the flywheel ring gear changes, it may be difficult to achieve a good fixing effect on the flywheel ring gear, and thus it is not convenient for the grinding process of the flywheel ring gear. Content of the Utility Model

[0004] The utility model provides a double-sided grinding device for flywheel ring gear processing to solve the problem that the types of flywheel ring gears that the fixture can fix are quite limited. When the type of the flywheel ring gear changes, it may be difficult to achieve a good fixing effect on the flywheel ring gear, and thus it is not convenient for the grinding process of the flywheel ring gear.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A double-sided grinding device for flywheel ring gear processing, including an operation table. The two sides of the top of the operation table are respectively rotatably connected with a first support and a second support. Electric telescopic rods are fixedly connected to the sides of the first support and the second support away from each other. The electric telescopic rods are arranged inside the inner wall of the operation table. Grinding discs are arranged at the bottom of the first support and the top of the second support. A motor is arranged at the bottom of the operation table. The output end of the motor passes through the inner wall of the operation table and is fixedly connected with a rotating shaft. Two clamping blocks are arranged at one end of the rotating shaft. An adjusting device is arranged between the two clamping blocks and the rotating shaft. The adjusting device includes a sleeve. One side of the sleeve is fixedly connected with one end of the rotating shaft. Extension blocks are fixedly connected to the two sides and the middle of the outer surface of the sleeve. The same threaded cylinder is fixedly connected to the inner walls of the two adjacent extension blocks. A threaded rod is threadedly connected to the inner wall of the threaded cylinder. A connecting block is arranged on the outer surface of the threaded rod. One side of the connecting block is fixedly connected with a rectangular plate. The outer surface of the rectangular plate is slidably connected with the inner wall of the sleeve. Support plates are symmetrically arranged at the bottom of the operation table. A connecting plate is fixedly connected to the sides of the two support plates close to each other. An auxiliary device is arranged between the two support plates and the operation table.

[0006] The effects achieved by the above components are as follows: By setting the rectangular plate, under the action of the threaded rod and the threaded barrel, when the threaded rod is rotated, the threaded rod will expand and contract on the inner wall of the threaded barrel. During the expansion and contraction process of the threaded rod, it will drive the rectangular plate connected to the connecting block to slide on the inner wall of the sleeve, and then drive the clamping block to move. Thus, it is convenient to adjust the distance between the two clamping blocks according to the actual inner diameter of the flywheel gear ring, so that the two clamping blocks can be adapted to flywheel gear rings of various models, effectively improving the practicality of the grinding device.

[0007] Preferably, a bearing is fixedly connected to the outer surface of the threaded rod, and the outer surface of the bearing is fixedly connected to the inner wall of the connecting block.

[0010] The effects achieved by the above components are as follows: By setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, protrusions are arranged on the outer surface of the operating block, which can effectively increase the friction on the outer surface of the operating block and play an anti-slip role when rotating the operating block.

[0011] Preferably, a nut is threadedly connected to the outer surface of the threaded rod, and the nut is arranged between the threaded barrel and the connecting block.

[0012] The effects achieved by the above components are as follows: By setting the nut and rotating the nut, one side of the nut abuts against one end of the threaded barrel, so that one end of the threaded rod can be limited, which is beneficial to preventing the contact between the clamping block and the inner wall of the flywheel gear ring from loosening.

[0013] Preferably, rubber blocks are fixedly connected to the sides of the two clamping blocks away from each other. One side of the rubber block is arc-shaped, and both ends of the rubber block are longer than both ends of the clamping block.

[0014] The effects achieved by the above components are as follows: By setting the rubber blocks, taking advantage of the deformable characteristics of the rubber blocks, one side of the clamping block can be in full contact with the inner wall of the flywheel gear ring, and the friction between the clamping block and the inner wall of the flywheel gear ring can be increased, making the fixation of the two clamping blocks on the flywheel gear ring more secure.

[0015] Preferably, the auxiliary device includes four rectangular rods. One end of each of the four rectangular plates is fixedly connected to the four corners of the bottom of the operating table. The inner walls of the two rectangular rods are both slidably connected to the inner wall of the support plate.

One side of the round hole blocks is fixedly connected to one side of the support plate.

[0016] The effects achieved by the above components are as follows: By pushing the threaded insertion rod to slide inside the inner wall of the round hole block, it will drive the rectangular plate to slide synchronously inside the inner wall of the support plate, and then drive the operating table to move in the vertical direction, facilitating the adjustment of the height of the operating table according to actual needs, and effectively improving the practicability of the grinding device.

[0017] Preferably, two screw hole blocks are threadedly connected to the outer surface of the threaded insertion rod, and the two screw hole blocks are respectively arranged on both sides of the round hole block.

[0018] The effects achieved by the above components are as follows: By setting two screw hole blocks and rotating the screw hole blocks so that one side of the screw hole block abuts against one side of the round hole block, the height of the operating table can be fixed.

[0019] Preferably, one end of the threaded insertion rod is fixedly connected with a round block, and the outer diameter of the round block is larger than the outer diameter of the threaded insertion rod.

[0020] The effects achieved by the above components are as follows: By setting the round block, the end of the threaded insertion rod can be limited, which is beneficial to preventing the nut and the round hole block from detaching from the threaded insertion rod.

[0028] Example 1, referring to Figures 1 - 3 as shown, this example discloses a double-sided grinding device for flywheel ring gear processing, including an operating table 1. The two sides of the top of the operating table 1 are respectively rotatably connected with a first bracket 2 and a second bracket 3. One side of the first bracket 2 and the second bracket 3 far away from each other are both fixedly connected with an electric telescopic rod 4. The electric telescopic rod 4 is arranged inside the inner wall of the operating table 1. Grinding discs 5 are arranged at the bottom of the first bracket 2 and the top of the second bracket 3. A motor 8 is arranged at the bottom of the operating table 1. The output end of the motor 8 passes through the inner wall of the operating table 1 and is fixedly connected with a rotating shaft 9. Two clamping blocks 10 are arranged at one end of the rotating shaft 9. An adjusting device 6 is arranged between the two clamping blocks 10 and the rotating shaft 9. The adjusting device 6 includes a sleeve 61. One side of the sleeve 61 is fixedly connected with one end of the rotating shaft 9. Two sides and the middle of the outer surface of the sleeve 61 are all fixedly connected with extension blocks 62. The inner walls of the two adjacent extension blocks 62 are fixedly connected with the same threaded barrel 63. The inner wall of the threaded barrel 63 is threadedly connected with a threaded rod 64. A connecting block 65 is arranged on the outer surface of the threaded rod 64. One side of the connecting block 65 is fixedly connected with a rectangular plate 66. The outer surface of the rectangular plate 66 is slidably connected with the inner wall of the sleeve 61. Support plates 11 are symmetrically arranged at the bottom of the operating table 1. A connecting plate 12 is fixedly connected between the two sides of the two support plates 11 close to each other. An auxiliary device 7 is arranged between the two support plates 11 and the operating table 1. By setting the rectangular plate 66, under the action of the threaded rod 64 and the threaded barrel 63, when the threaded rod 64 is rotated, the threaded rod 64 will expand and contract inside the inner wall of the threaded barrel 63. During the expansion and contraction process of the threaded rod 64, it will drive the rectangular plate 66 connected to the connecting block 65 to slide inside the inner wall of the sleeve 61, and then drive the clamping block 10 to move. Then, it is convenient to adjust the distance between the two clamping blocks 10 according to the actual inner diameter of the flywheel ring gear, so that the two clamping blocks 10 can be adapted to flywheel ring gears of various models, effectively improving the practicability of the grinding device.

[0029] Referring to Figure 2 and Figure 3As shown, a bearing 67 is fixedly connected to the outer surface of the threaded rod 64, and the outer surface of the bearing 67 is fixedly connected to the inner wall of the connecting block 65. By providing the bearing 67, when the threaded rod 64 is rotated, the frictional force between the threaded rod 64 and the connecting block 65 can be reduced, making it more labor-saving to rotate the threaded rod 64; one end of the threaded rod 64 is fixedly connected to an operating block 68, and protrusions are provided on the outer surface of the operating block 68. By providing the operating block 68, rotating the operating block 68 can drive the threaded rod 64 to rotate. At the same time, the protrusions provided on the outer surface of the operating block 68 can effectively increase the frictional force on the outer surface of the operating block 68, playing an anti-slip role when rotating the operating block 68.

[0030] Referring to Figure 2 and Figure 3 As shown, a nut 69 is threadedly connected to the outer surface of the threaded rod 64. The nut 69 is arranged between the threaded cylinder 63 and the connecting block 65. By providing the nut 69 and rotating the nut 69, one side of the nut 69 abuts against one end of the threaded cylinder 63, then the one end of the threaded rod 64 can be limited, which is beneficial to preventing the contact between the clamping block 10 and the inner wall of the flywheel ring gear from becoming loose; rubber blocks 610 are fixedly connected to the mutually remote sides of the two clamping blocks 10. One side of the rubber block 610 is arc-shaped, and both ends of the rubber block 610 are longer than both ends of the clamping block 10. By providing the rubber blocks 610 and utilizing the characteristic that the rubber blocks 610 are conducive to deformation, one side of the clamping block 10 can be fully contacted with the inner wall of the flywheel ring gear, and the frictional force between the clamping block 10 and the inner wall of the flywheel ring gear can be increased, making the fixation of the two clamping blocks 10 on the flywheel ring gear more tight.

[0031] Referring to Figure 2 and Figure 4 As shown, the auxiliary device 7 includes four rectangular rods 71. One ends of the four rectangular plates 66 are respectively fixedly connected to the four corners at the bottom of the operating table 1. The inner walls of the two rectangular rods 71 are both slidably connected to the inner wall of the support plate 11. Threaded insertion rods 72 are symmetrically and fixedly connected to the top of the operating table 1. The outer surface of the threaded insertion rod 72 is slidably connected to a round hole block 73. One side of the round hole block 73 is fixedly connected to one side of the support plate 11. By providing the threaded insertion rod 72 and pushing the threaded insertion rod 72 to slide inside the inner wall of the round hole block 73, the rectangular plate 66 can be driven to slide synchronously inside the inner wall of the support plate 11, thereby driving the operating table 1 to move in the vertical direction, facilitating the adjustment of the height of the operating table 1 according to actual needs, and effectively improving the practicability of the grinding device.

[0032] Referring to Figure 2 and Figure 4As shown, two screw hole blocks 74 are threadedly connected to the outer surface of the threaded insertion rod 72. The two screw hole blocks 74 are respectively arranged on both sides of the round hole block 73. By setting the two screw hole blocks 74 and rotating the screw hole blocks 74 so that one side of the screw hole block 74 abuts against one side of the round hole block 73, the height of the operating table 1 can be fixed; one end of the threaded insertion rod 72 is fixedly connected with a round block 75, and the outer diameter of the round block 75 is larger than the outer diameter of the threaded insertion rod 72. By setting the round block 75, one end of the threaded insertion rod 72 can be limited, which is beneficial to preventing the nut 69 and the round hole block 73 from detaching from the threaded insertion rod 72.

[0033] Working principle: When it is necessary to adjust the distance between the two clamping blocks 10, rotate the two operating blocks 68 respectively to drive the threaded rod 64 to rotate. The threaded rod 64 will expand and contract on the inner wall of the threaded cylinder 63. During the expansion and contraction process of the threaded rod 64, the rectangular plate 66 connected to the connecting block 65 will slide on the inner wall of the sleeve 61, and then drive the clamping block 10 to move until the distance between the two clamping blocks 10 is adapted to the actual inner diameter of the flywheel gear ring, so that one side of the rubber block 610 abuts against the inner wall of the flywheel gear ring. Then rotate the nut 69 so that one side of the nut 69 abuts against one end of the threaded cylinder 63, then the end of the threaded rod 64 can be limited, which is beneficial to preventing the abutment between the clamping block 10 and the inner wall of the flywheel gear ring from loosening; when it is necessary to adjust the height of the operating table 1, push the threaded insertion rod 72 to slide on the inner wall of the round hole block 73, which will drive the rectangular plate 66 to slide synchronously on the inner wall of the support plate 11, and then drive the operating table 1 to move in the vertical direction until it reaches the appropriate height. Then rotate the screw hole block 74 so that one side of the screw hole block 74 abuts against one side of the round hole block 73, then the height of the operating table 1 can be fixed.
