Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a workpiece clamping mechanism for a flywheel double-sided synchronous grinding machine. Background Technology

[0002] In the manufacturing process of flywheels, double-sided synchronous grinding is a key process to ensure the flatness and dimensional accuracy of both sides of the flywheel. The flatness and dimensional accuracy of both sides of the flywheel are important factors in whether the flywheel can be used normally and safely.

[0003] However, existing technologies have the problem that only one flywheel can be ground at a time, resulting in low work efficiency, greatly increasing the labor intensity of workers, and the quality of individually processed products is prone to inconsistency. Therefore, a workpiece clamping mechanism for a flywheel double-sided synchronous grinding machine tool is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a workpiece clamping mechanism for a flywheel double-sided synchronous grinding machine, so as to solve the problem mentioned in the background art that only one flywheel can be ground at a time, resulting in low work efficiency, greatly increasing the labor intensity of workers, and the quality of individual processed products is prone to be inconsistent.

[0007] Preferably, the output end of the electric telescopic rod is fixedly connected to a protective cover, the shape of which is adapted to the inner wall of the limiting box.

[0008] Preferably, the upper surface of the toothed ring is provided with circumferentially distributed limiting holes.

[0010] Preferably, the edge of the second friction plate is fixedly connected with limiting posts in a circumferential distribution, and the shape of the multiple limiting posts is adapted to the shape of the multiple limiting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The workpiece clamping mechanism of this flywheel double-sided synchronous grinding machine first rotates the handle, causing the slider to rotate inside the slide groove, compressing the spring, so that the slot coincides with the central shaft gear ring of the slot on the slider. Then, multiple flywheels are placed in different slots. Releasing the handle returns the spring to its original position. Under the support and fixation of the fixed column, the spring pushes the slider to rotate inside the slide groove, so that the slider and the slot clamp and fix multiple flywheels, limiting the position of the flywheels. This allows the device to grind multiple flywheels simultaneously during grinding operations, improving processing efficiency and avoiding inconsistent product quality. Attached Figure Description

Detailed Implementation

[0014] Please see Figure 1-5This utility model provides a technical solution: a workpiece clamping mechanism for a flywheel double-sided synchronous grinding machine, including a worktable 1. A limit box 4 is fixedly connected to the lower surface of the worktable 1. A first friction plate 8 is fixedly connected to the inner bottom wall of the limit box 4. The first friction plate 8 is used to grind the bottom of the flywheel. A gear ring 5 is fixedly connected to the upper surface of the first friction plate 8. A motor 14 is fixedly connected to the lower surface of the limit box 4. A transmission gear 7 is fixedly connected to the output end of the motor 14 through a coupling. The motor 14 drives the transmission gear 7 to rotate. The outer surface of the transmission gear 7 meshes with a limit gear 10. The transmission gear 7 drives the limit gear 10 to rotate. Three slots 20 are provided on the upper surface of the limit gear 10. The slots 20 are used to limit and fix the position of the flywheel. The side of the outer surface of the limit gear 10 away from the transmission gear 7 meshes with the inner wall of the gear ring 5. Through the transmission gear 7, the limit gear 10, and the gear ring... 5. When used in conjunction, the flywheel fixed by the limiting gear 10 rotates around the transmission gear 7 inside the device while simultaneously rotating on its own, making the grinding surface smoother. The limiting gear 10 has a groove 11 inside, and a slider 12 is rotatably connected inside the groove 11. The groove 11 serves to limit the position of the slider 12. A handle 13 is fixedly connected to the upper surface of the slider 12. The handle 13 drives the slider 12 to rotate inside the groove 11, which is used to place the flywheel to be ground inside the slot 20 and clamp it by the slider 12. A groove 18 is opened on the upper surface of the slider 12. A fixing post 9 is fixedly connected to the inner wall of the limiting gear 10. A spring 19 is fixedly connected to one side of the fixing post 9. The fixing post 9 serves to limit the position of the spring 19, so that the spring 19 pushes the slider 12 to rotate inside the groove 11. The end of the spring 19 away from the fixing post 9 is fixedly connected to the inner wall of the groove 18.

[0015] The upper surface of the workbench 1 is fixedly connected to a support frame 2, and the lower surface of the support frame 2 is fixedly connected to an electric telescopic rod 15. The support frame 2 serves to limit and fix the position of the electric telescopic rod 15.

[0016] The output end of the electric telescopic rod 15 is fixedly connected to a protective cover 3. The shape of the protective cover 3 is adapted to the inner wall of the limit box 4. The protective cover 3 is used in conjunction with the limit box 4 to prevent grinding debris from accidentally splashing outside the device during the grinding of the flywheel.

[0017] Among them, the upper surface of the toothed ring 5 is provided with circumferentially distributed limiting holes 6.

[0018] The lower surface of the protective cover 3 is fixedly connected to a second friction plate 17, which serves to grind the upper surface of the flywheel.

[0019] Among them, the edge of the second friction plate 17 is circumferentially distributed and fixedly connected with limit posts 16. The shape of the multiple limit posts 16 is adapted to the shape of the multiple limit holes 6. By using the limit posts 16 and the limit holes 6 in combination, the positions of the first friction plate 8 and the second friction plate 17 are relatively fixed, which plays a role in ensuring the grinding quality of the flywheel.

[0020] Among them, the motor 14 is existing technology and will not be described in detail here. Matching the motor 14 are connecting wires, power supply, microcontroller, etc., which are existing structures and will not be described in detail here.

[0021] Working principle: In use, first turn the handle 13, causing the slider 12 to rotate inside the slide groove 11, compressing the spring 19, so that the slot 20 coincides with the central shaft gear ring 5 of the slot on the slider 12. Then, place the flywheel in the slot 20, release the handle 13, and the spring 19 returns to its original position. Under the support and fixation of the fixing column 9, the spring 19 pushes the slider 12 to rotate inside the slide groove 11, so that the slider 12 cooperates with the slot 20 to clamp and fix the flywheel, limiting the position of the flywheel. After all the flywheels in the device are fixed, start the electric telescopic rod 15, causing the electric telescopic rod 15 to move the protective cover 3 downward. The protective cover 3 inserts into the interior of the limiting box 4, achieving a seal between the first friction plate 8 and the second friction plate 17, preventing the first friction plate 8 and the second friction plate 17 from... When grinding the flywheel, grinding debris may accidentally fly out and injure the workers. The protective cover 3 continues to move downwards until the limiting post 16 is inserted into the limiting hole 6, fixing the relative positions of the gear ring 5 and the second friction plate 17. The limiting post 16, in conjunction with the limiting hole 6, ensures the parallelism between the second friction plate 17 and the first friction plate 8. When the first friction plate 8 and the second friction plate 17 contact the upper and lower surfaces of the flywheel respectively, the motor 14 is started. The motor 14 drives the transmission gear 7 to rotate, causing the transmission gear 7 to mesh with the limiting gear 10. Simultaneously, the limiting gear 10 meshes with the gear ring 5, causing the limiting gear 10 to rotate circumferentially around the transmission gear 7 inside the device while also rotating on its own axis. This allows the flywheel to perform multi-directional grinding, improving the grinding quality.
