Detailed Implementation
[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an engine cylinder head machining clamping device, including a base plate 1. A rotating mechanism is provided inside the base plate 1. An mounting plate 2 is installed at the top of the rotating mechanism. An adjusting mechanism is provided at the top of the mounting plate 2. A clamping plate 3 is installed at the top of the adjusting mechanism. A cylinder 4 is installed at the top of the clamping plate 3. A positioning block 5 is installed at the top of the cylinder 4.
[0020] The adjustment mechanism includes a mounting cavity 6, a first servo motor 7, a worm gear 8, a worm wheel 9, a connecting rod 10, and a guide structure. The mounting cavity 6 is installed at the middle position of the top of the mounting plate 2. The first servo motor 7 is installed at one end of the mounting cavity 6, and the worm gear 8 is installed at the lower part inside the mounting cavity 6. The output end of the first servo motor 7 is connected to one end of the worm gear 8. The worm wheel 9 is meshed above the worm gear 8, and the connecting rod 10 is installed at one end of the worm wheel 9. The top end of the connecting rod 10 is connected to the bottom end of the clamping plate 3. In use, the first servo motor 7 is started to drive the worm gear 8 to rotate. Since the worm gear 8 and the worm wheel 9 are meshed with each other, the worm gear 8 drives the worm wheel 9 to rotate, which in turn drives the connecting rod 10 to rotate. At this time, under the guidance of the guide rail 11, the guide wheel 12, and the mounting rod 13, the connecting rod 10 drives the clamping plate 3 to rotate, thereby adjusting the angle of the engine cylinder head, making the engine cylinder head processing more efficient, and thus greatly improving the working efficiency of the device in use.
[0021] The guiding structure includes a guide rail 11, a guide wheel 12, and a mounting rod 13. The guide rail 11 is mounted on the top of the mounting plate 2. The guide wheel 12 is provided on the inner side of the guide rail 11. The mounting rod 13 is mounted above the guide wheel 12. The top of the mounting rod 13 is connected to the bottom of the clamping plate 3. There are two guide rails 11 on the top of the mounting plate 2. The two guide rails 11 are symmetrically distributed about the central axis of the mounting plate 2. In use, the guide wheel 12 slides inside the guide rail 11. With the cooperation of the mounting rod 13, the clamping plate 3 is guided when it rotates, making the clamping plate 3 more stable when rotating.
[0022] The rotating mechanism includes a second servo motor 14, a transmission rod 15, a first bevel gear 16, a second bevel gear 17, and a limiting structure. The second servo motor 14 is mounted on one end of the base plate 1. The output end of the second servo motor 14 is equipped with the transmission rod 15, one end of which extends into the interior of the base plate 1. The first bevel gear 16 is mounted on one end of the transmission rod 15. The bottom end of the first bevel gear 16 meshes with the second bevel gear 17. The top end of the second bevel gear 17 is connected to the bottom end of the mounting plate 2. In use, the second servo motor 14 is started to drive the transmission rod 15 to rotate, which in turn drives the first bevel gear 16 to rotate. Since the first bevel gear 16 and the second bevel gear 17 mesh with each other, the second bevel gear 17 is driven to rotate. Under the limiting position of the limiting groove 18 and the limiting block 19, the second bevel gear 17 drives the mounting plate 2 to rotate, which in turn drives the engine cylinder head to rotate. This makes the engine cylinder head more efficient during processing, thereby greatly improving the practicality of the device in use.
[0023] The limiting structure includes a limiting groove 18 and a limiting block 19. The limiting groove 18 is formed inside the base plate 1, and the limiting block 19 is provided inside the limiting groove 18. The top end of the limiting block 19 is connected to the bottom end of the mounting plate 2. The cross-section of the limiting groove 18 is larger than the cross-section of the limiting block 19. The limiting groove 18 and the limiting block 19 form a sliding structure. In use, the mutual cooperation between the limiting groove 18 and the limiting block 19 can limit the rotation of the mounting plate 2, making the mounting plate 2 more stable when rotating.
[0024] Working principle: The operator first places the engine cylinder head on the top of the clamping plate 3, then starts the cylinder 4 to move the positioning block 5, using the positioning block 5 to clamp and fix the engine cylinder head. At this time, the engine cylinder head can be processed. When it is necessary to adjust the angle of the engine cylinder head, the first servo motor 7 is started to drive the worm 8 to rotate. Since the worm 8 and the worm wheel 9 are meshed with each other, the worm 8 drives the worm wheel 9 to rotate, which in turn drives the connecting rod 10 to rotate. At this time, under the guidance of the guide rail 11, guide wheel 12 and mounting rod 13, The connecting rod 10 drives the clamping plate 3 to rotate, thereby adjusting the angle of the engine cylinder head. Then, the second servo motor 14 is started to drive the transmission rod 15 to rotate, which in turn drives the first bevel gear 16 to rotate. Since the first bevel gear 16 and the second bevel gear 17 mesh with each other, the second bevel gear 17 is driven to rotate. Under the limitation of the limiting groove 18 and the limiting block 19, the second bevel gear 17 drives the mounting plate 2 to rotate, thereby driving the engine cylinder head to rotate, making the engine cylinder head more efficient during processing.
