Description

Technical Field

[0001] This invention relates to the field of flywheel drilling technology, and in particular to a lathe for machining metal parts. Background Technology

[0002] A flywheel is a mechanical device used to store rotational kinetic energy during rotational motion. It is used in many fields, such as engines, compressors, and mechanical equipment.

[0003] In small and medium-sized factories with low levels of automation, the flywheel needs to be fixed before drilling holes in the flywheel of a car clutch. The drilling process is divided into vertical fixing and horizontal fixing. The requirements for drilling in the two methods are different. For small and medium-sized factories with low precision, vertical drilling is more common. The flywheel is placed on the slide rail, the position of the fixing unit is adjusted, the flywheel is clamped and fixed on the fixing unit, and then the drilling unit is started to drill holes in the fixed flywheel.

[0004] However, before the actual drilling operation, the workers need to pick up the flywheel and align it with the center of the fixed unit on the equipment, adjust the position of the fixed unit and the flywheel, fix the flywheel and manually rotate the flywheel, use a self-made detection device to closely observe whether there is any deviation when the flywheel rotates, and use a hammer to tap the flywheel at the deviation position. The above positioning steps are tedious and complicated, which increases the workload of the workers and reduces the working efficiency of flywheel drilling.

[0005] Therefore, this application provides a lathe for machining metal parts to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide a lathe for machining metal parts. By setting up a positioning component, the operator does not need to continuously hold the flywheel during operation, which reduces the difficulty of the operation. The placement column can also be used to quickly correct the rotation trajectory of the flywheel, reducing the manual hammering and correction steps, reducing the workload of the operator, and improving the drilling efficiency of the flywheel. The above settings can solve the problem that the existing method of manually fixing and adjusting the position of the fixing unit and the flywheel is cumbersome and complicated, increases the workload, and reduces the drilling efficiency of the flywheel.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A lathe for machining metal parts includes a lathe body and a worktable. A positioning clamp is slidably connected to the top of the worktable. A flywheel is attached to the outer wall of the positioning clamp. A placement post is engaged with the outer wall at the end of the positioning clamp. A bonding plate is engaged with the outer wall of the positioning clamp away from the placement post. A positioning assembly is used to assist in the placement and fixing of the flywheel. The positioning assembly is connected to the positioning clamp.

[0009] Optionally, a weakening part is provided at the middle position of the side arc plate near the outer wall of the second force plate, a rotating column is fixedly connected to the bottom of the side arc plate, a limit buckle is fixedly connected to the outer wall of the rotating column, and an adjusting plate is fixedly connected to the outer wall of the rotating column.

[0010] Optionally, an adapter is fixedly connected to the outer wall of the top of the adjusting plate, a snap-fit ​​post is fixedly connected to the outer wall of the top of the adjusting plate, lower tension plates are fixedly connected to both ends of the second force plate, and an upper tension plate is fixedly connected to the middle position of the outer wall of the top of the adjusting plate.

[0011] Optionally, the positioning clip has push grooves at both ends, a push plate is slidably connected to the inner wall of the push groove, an adapter block is fixedly connected to the middle position of the outer wall of the placement column, and an abutment column is installed on the inner wall of the positioning clip.

[0012] Optionally, the outer wall of the positioning clip is engaged with a limiting post, the outer wall of the bonding plate is fixedly connected with a protective sleeve, and a deformation ring is fixedly connected to the middle position of the bonding plate near the outer wall of the positioning clip.

[0013] Optionally, the top of the positioning clip has an arc-shaped structure, the bottom has a clamping sliding structure, the placement column has a gradient structure, the bonding plate has an arc-shaped design, and a snap-fit ​​groove is provided in the middle of the outer wall of the positioning clip.

[0014] Optionally, the contact block is made of rubber, the middle position of the first force plate protrudes downward, and the outer wall of the fixing plate is fixedly connected to the inner wall of the bottom of the positioning clip.

[0015] Optionally, the rotating column is provided with fixed columns at both ends, the fixed columns are fixedly connected to the bottom of the side arc plate, the size of the adapter part is adapted to the size of the adapter groove, the size of the snap-fit ​​column is adapted to the size of the snap-fit ​​hole, and the lower tension plate and the upper tension plate are snapped together.

[0016] Optionally, the size of the middle position of the placement column is adapted to the size of the pushing groove, the abutting column is provided with an elastic rope, the end of the elastic rope away from the abutting column is fixedly connected to the inner wall of the positioning clip, the adapter block is spirally distributed in the middle position of the outer wall of the placement column, the size of the snap-fit ​​groove is consistent with the small diameter of the placement column, and the deformation ring has a hollow design inside.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a positioning component, the operator does not need to hold the flywheel continuously during operation, which reduces the difficulty of the operation. Furthermore, when fixing the flywheel, the placement column can be used to quickly correct the rotation trajectory of the flywheel, reducing the need for manual tapping and correction by the operator, thus reducing the workload of the operator and improving the efficiency of flywheel drilling.

[0018] By incorporating a weakening section, a rotating column, and a limiting buckle in the positioning assembly, when the adjusting plate is pulled upwards under force, the rotating column will rotate under the upward force. At the same time, the pulling will also cause the bottom of the side arc plate to bend upwards. The weakening section can effectively reduce the bending creases formed after the bottom of the side arc plate bends, and the limiting buckle can alleviate the creases at the weakening section, reduce bending fatigue, and improve the service life of the equipment.

[0019] By incorporating a contact block, a first force plate, a second force plate, and a recessed groove into the positioning assembly, when the flywheel is placed on the first force plate, its shape gradually positions it in the middle of the two positioning clips. During continuous downward pressure, the first force plate gradually contacts the second force plate and the recessed groove, thereby alleviating the pressure from the flywheel's own weight. This makes the flywheel placement process smoother and more convenient. Furthermore, the contact block can better limit the flywheel's position, further improving the stability of the flywheel during placement.

[0020] By setting up placement columns, push plates, push grooves, adapter blocks, contact columns, and bonding plates, the rotation surface of the flywheel is adjusted after the flywheel is fixed. The push of the placement columns makes both sides of the flywheel have the same value. After the flywheel is engaged with the fixing unit, a slight rotation of the flywheel can be used to observe whether there is any deviation during rotation, which effectively improves the efficiency of the workers' adjustment and ensures the progress of drilling holes in the flywheel.

[0030] like Figures 1 to 14 As shown, an embodiment of the present invention provides a lathe for machining metal parts, including a lathe body 1 and a worktable 2. A positioning clamp 3 is slidably connected to the top of the worktable 2. A flywheel 4 is attached to the outer wall of the positioning clamp 3. A placement post 21 is snapped onto the outer wall of the end of the positioning clamp 3. A bonding plate 26 is snapped onto the outer wall of the positioning clamp 3 away from the placement post 21. A positioning assembly is used to assist in the placement and fixing of the flywheel 4. The positioning assembly is connected to the positioning clamp 3. The top of the positioning clamp 3 has an arc-shaped structure, and the bottom has a clamping sliding structure. The placement post 21 has a gradient structure, and the bonding plate 26 has an arc-shaped design. A snap-fit ​​groove is opened in the middle of the outer wall of the positioning clamp 3. The lathe body 1, the worktable 2, and the flywheel 4 are existing structures, and will not be described in detail. The positioning clamp 3 is made of metal. A small amount of lubricating oil can be applied to the bottom before sliding to reduce the friction between the bottom of the positioning clamp 3 and the top of the worktable 2, which facilitates the adjustment by the operator. There are two positioning clamps 3, which are symmetrically distributed.

[0031] Workflow: First, the flywheel 4 and related equipment are selected and inspected. Then, the flywheel 4 is placed on a special drilling device, usually by magnetic attraction or snap-fit. After the flywheel 4 is fixed in position, drilling begins. The drilling direction and trajectory are in accordance with the design requirements of the flywheel 4. During drilling, coolant is rotated to prevent the drill bit from overheating. After drilling, professional measuring tools are used to measure the hole diameter and roundness. Finally, the surface of the flywheel 4 and the drilling debris are collected and cleaned.

[0032] By setting up a positioning component, the operator does not need to hold the flywheel 4 continuously during operation, which reduces the difficulty of the operation. Furthermore, when fixing the flywheel 4, the rotation trajectory of the flywheel 4 can be quickly corrected by using the placement column 21, which reduces the need for the operator to manually tap and correct the rotation, thus reducing the workload of the operator and improving the drilling efficiency of the flywheel 4.

[0033] like Figures 5 to 10The positioning assembly includes a contact block 5 fixedly connected to the outer wall of the positioning clamp 3. A first force-bearing plate 6 is fixedly connected to the outer wall of the positioning clamp 3. A second force-bearing plate 7 is attached to the middle position of the bottom of the first force-bearing plate 6. Fixing plates 11 are fixedly connected to both sides of the second force-bearing plate 7. A side arc plate 8 is fixedly connected to the outer wall of the positioning clamp 3. A recessed groove 9 is formed in the middle position of the second force-bearing plate 7. Adaptive grooves 10 are formed at both ends of the second force-bearing plate 7. Snap-fit ​​holes 12 are formed at both ends of the second force-bearing plate 7. A weakening part 13 is provided at the middle position of the outer wall of the second stress plate 7 near the plate 8. A rotating column 14 is fixedly connected to the bottom of the side arc plate 8. A limit buckle 15 is fixedly connected to the outer wall of the rotating column 14. An adjusting plate 16 is fixedly connected to the outer wall of the rotating column 14. An adapter part 17 is fixedly connected to the outer wall of the top of the adjusting plate 16. A locking column 18 is fixedly connected to the outer wall of the top of the adjusting plate 16. Lower tension plates 19 are fixedly connected to both ends of the second stress plate 7. An upper tension plate is fixedly connected to the middle position of the top outer wall of the adjusting plate 16. The tension plate 20 and contact block 5 are made of rubber. The middle of the first force plate 6 protrudes downwards. The outer wall of the fixing plate 11 is fixedly connected to the inner wall of the bottom of the positioning clamp 3. The two ends of the rotating column 14 are provided with fixing columns, which are fixedly connected to the bottom of the side arc plate 8. The size of the adapter part 17 matches the size of the adapter groove 10. The size of the snap-fit ​​post 18 matches the size of the snap-fit ​​hole 12. The lower tension plate 19 and the upper tension plate 20 snap each other together. The distance between the two contact blocks 5 is less than the distance between the two positioning clamps 3. The distance between them, the first force plate 6 and the second force plate 7 are both made of metal, the hardness of the second force plate 7 is greater than that of the first force plate 6, a placement groove is opened in the middle of the top of the side arc plate 8, the side arc plate 8, the second force plate 7 and the fixing plate 11 together connect the two positioning clips 3 to each other to form a whole, the top of the adjusting plate 16 is engaged with both ends of the second force plate 7, and the engagement between the engaging post 18, the lower tension plate 19 and the upper tension plate 20 forms a semi-fixed state that can be swayed.

[0034] With the above structure, the worker applies a small amount of lubricating oil to the bottom of the positioning clamp 3, and then places the positioning clamp 3 horizontally on the top of the workbench 2. Before placing the flywheel 4, the worker can hold the positioning clamp 3 and slide it along its outer wall. This checks whether there is any obvious shaking during the sliding process, and also allows the lubricating oil at the bottom of the positioning clamp 3 to slide to the top of the workbench 2, improving the sliding effect between the workbench 2 and the positioning clamp 3. Then, the worker stops sliding the positioning clamp 3 and places the flywheel 4 in the middle of the positioning clamp 3. When placing the flywheel 4, ensure that the bottom of the flywheel 4 is in the middle of the two positioning clamps 3. Regardless of whether the flywheel 4 is correctly placed in the middle of the two positioning clamps 3, the outer edge of the flywheel 4... Upon contact with the first support plate 6, because the weight of the flywheel 4 exceeds the pressure that the first support plate 6 can withstand, the first support plate 6 will deform downwards and move closer to the second support plate 7. The shape of the middle part of the first support plate 6 is "U", so that the flywheel 4 will automatically be in the middle position of the first support plate 6 during the downward placement process. As the flywheel 4 continues to apply pressure to the first support plate 6, the first support plate 6 will continuously move downwards. When the bottom of the first support plate 6 contacts the second support plate 7, it will continue to move downwards along the middle sink groove 9 of the second support plate 7. When the first support plate 6 presses towards the sink groove 9, the second support plate 7 will also deform. The deformation of the second support plate 7 will cause the adjusting plates 16 at both ends to move as well. At this time, refer to... Figure 6 If the middle of the second force-bearing plate 7 is pressed downwards, both ends of the second force-bearing plate 7 will lift up, from Figure 9As can be seen, the adjusting plate 16, secured by the adapter 17, the snap-fit ​​post 18, and the lower tensioning plate 19, is pulled upwards as the two ends of the second force plate 7 tilt upwards. Consequently, the rotating column 14 rotates due to the lifting of the adjusting plate 16. During rotation, the limiting buckle 15 gradually approaches and abuts against the middle position of the bottom of the side arc plate 8, thus limiting further rotation of the rotating column 14 and preventing large-angle rotation of the rotating column 14. If the adjusting plate 16 continues to pull upwards after the rotation ends, the upward force will be concentrated on the limiting buckle 15 and the adjusting plate 16. At this time, the lower tensioning plate... The interlocking and pulling effect between the 19 and the upper tension plate 20 becomes more pronounced as the adjusting plate 16 is pulled upwards. In actual operation, the flywheel 4, being heavy, sinks quickly after being placed on the first force plate 6. Pressure gradually transfers from the first force plate 6 to the second force plate 7 and continues along the adjusting plate 16, rotating column 14, and limit buckle 15. Then, the adapter 17 and locking column 18 share some of the pressure. Following this, the bottom of the side arc plate 8 bends upwards. To reduce the appearance of bending creases on the side arc plate 8 after repeated use, which would affect the side... The overall strength of the arc plate 8 is enhanced by a weakening section 13 located in the middle of the side arc plate 8, which actively weakens bending creases. After the worker places the flywheel 4 completely on the first force plate 6, and after a series of pressure transmissions, the bottom of the flywheel 4 rests directly on the placement groove at the top of the side arc plate 8. At this point, the first force plate 6 is in its maximum downward deformation state. The sinking groove 9 in the middle of the second force plate 7 catches the deformed first force plate 6, acting as a buffer. The remaining components, as detailed in the pressure transmission process, are all in normal working condition, thus ensuring the flywheel 4 is properly secured. The flywheel 4 is positioned at the midpoint between the two positioning clips 3, and the outer edge of the bottom of the flywheel 4 will not contact the top of the worktable 2. This prevents the flywheel 4 from sliding normally due to the outer edge of the flywheel 4 hitting the worktable 2 during the subsequent sliding of the positioning clips 3. Finally, the contact block 5 is made of rubber, which allows for greater deformation. When the flywheel 4 is in a stable state, the two contact blocks 5 will also completely adhere to the outer wall of the flywheel 4, limiting the flywheel 4 from the middle position near the flywheel 4. Thus, the flywheel 4 is fixed from the bottom and middle, preventing the flywheel 4 from shaking during the sliding of the positioning clips 3.

[0035] It is worth mentioning that when the flywheel 4 is placed downwards, the pressure of the flywheel 4 will cause the lower tension plate 19 and the upper tension plate 20 to be pulled. Since the upper tension plate 20 is fixed at both ends of the second force plate 7 and the lower tension plate 19 is fixed on the side of the top of the side arc plate 8, the downward pressure of the second force plate 7 will make the pulling effect of the upper tension plate 20 better. Similarly, the lifting effect of the adjusting plate 16 will also make the pulling effect of the lower tension plate 19 better, thus improving the locking effect between the adjusting plate 16 and the second force plate 7. At the same time, the semi-fixed structure between the adjusting plate 16 and the second force plate 7 is also more conducive to the placement of the flywheel 4.

[0036] By setting a weakening part 13, a rotating column 14, and a limiting buckle 15 in the positioning assembly, when the adjusting plate 16 is pulled upward by force, the rotating column 14 will rotate under the upward pulling force. At the same time, the pulling will also cause the bottom of the side arc plate 8 to bend upward. The weakening part 13 can effectively reduce the bending crease formed after the bottom of the side arc plate 8 bends, and the limiting buckle 15 can alleviate the crease at the weakening part 13, reduce bending fatigue, and improve the service life of the equipment.

[0037] By setting contact block 5, first force plate 6, second force plate 7 and sink groove 9 in the positioning component, when the flywheel 4 is placed on the first force plate 6, the shape of the first force plate 6 makes the flywheel 4 gradually move to the middle position of the two positioning clamps 3. During the continuous pressing process, the first force plate 6 gradually contacts the second force plate 7 and sink groove 9, thereby relieving the pressure brought by the flywheel 4's own weight, making the flywheel 4 easier and more convenient to place. The contact block 5 can better limit the position of the flywheel 4, further improving the stability of the flywheel 4 during placement.

[0038] like Figures 11 to 14As shown, the positioning clamp 3 has push grooves 23 at both ends, and push plates 22 are slidably connected to the inner walls of the push grooves 23. An adapter block 24 is fixedly connected to the middle position of the outer wall of the placement column 21. An abutment column 25 is installed on the inner wall of the positioning clamp 3. A limit column 27 is engaged with the outer wall of the positioning clamp 3. A protective sleeve 28 is fixedly connected to the outer wall of the fitting plate 26. A deformation ring 29 is fixedly connected to the middle position of the fitting plate 26 near the outer wall of the positioning clamp 3. The size of the middle position of the placement column 21 is adapted to the size of the push groove 23. An elastic rope is provided on the abutment column 25. The end of the elastic rope away from the abutment column 25 is fixedly connected to the inner wall of the positioning clamp 3. The adapter blocks 24 are spirally distributed on the placement column 21. In the middle of the outer wall, the size of the snap-fit ​​groove is the same as the small diameter of the placement column 21. The deformation ring 29 has a hollow design inside. The placement column 21 has a degree value near the large diameter end. The positioning clip 3 is located on the inner wall of the push groove 23 with different dimensions. According to the diagram, the push groove 23 on the left is smaller than the push groove 23 on the right. The abutment column 25 is distributed in a circumferential array inside the push groove 23 on the right side. In the initial state, the abutment column 25 is stationary, just like the push plate 22. If the positioning clip 3 is tilted, the push plate 22 will slide outward. However, the abutment column 25 is fixed by a traction rope and cannot slide by its own weight.

[0039] With the above structure, after the flywheel 4 is placed, hold the large-diameter end of the placement post 21 and insert the placement post 21 from one side of the positioning clamp 3. Align the adapter blocks 24 on the placement post 21 with the slots on the pushing groove 23 one by one. As mentioned above, the abutment posts 25 and the pushing plate 22 are arranged in a circumferential array, while the adapter blocks 24 are arranged in a threaded pattern. During the pushing process, the adapter blocks 24 will contact and press against the abutment posts 25 one by one. Thus, the placement post 21 pushes and drives the adapter blocks 24. The adapter blocks 24 will then slide and press inside the positioning clamp 3, driving the abutment posts 25 and 26. 5. After the sliding of the contact post 25, the traction rope fixed to the contact post 25 is pulled. Then, the sliding of the contact post 25 will squeeze the push plate 22, causing the push plate 22 to slide inside the push groove 23 until the small diameter end of the placement post 21 slides out of the push groove 23 and moves towards the middle position of the bonding plate 26. When the small diameter end of the placement post 21 does not abut against the deformation ring 29 in the middle position of the bonding plate 26, the bonding plate 26 is fixed by the limiting post 27 being engaged with the positioning clip 3 near the push groove 23, thereby preventing the small diameter end of the placement post 21 from abutting against the deformation ring 29 in the middle position of the bonding plate 26. When the smaller diameter end of the placement post 21 has not yet emerged from the push groove 23, the bonding plate 26 is snapped and fixed to the side of the positioning clamp 3. After the smaller diameter end of the placement post 21 emerges, it directly abuts against the deformation ring 29 in the middle of the bonding plate 26, thereby gradually pushing the limiting post 27 out of the inner wall of the positioning clamp 3. It is worth noting that the limiting post 27 will not completely detach from the interior of the positioning clamp 3, ensuring the relative stability of the bonding plate 26. The smaller diameter end of the placement post 21 will continuously approach and press against the deformation ring 29. Since the deformation ring 29 is hollow inside, it facilitates the contact between the smaller diameter end of the placement post 21 and the deformation ring 29. The inner wall of the deformation ring 29 is engaged until the bonding plate 26 is attached to the surface of the flywheel 4 on the side of the flywheel 4. At this time, the pushing of the placement column 21 is stopped. Observe the value of the large diameter end of the placement column 21. After completing one side of the positioning clamp 3, the other side is done in the same way. Finally, slide the entire positioning clamp 3 onto the fixing unit and fix it. At this time, due to the limitation of the middle and bottom, the flywheel 4 can move vertically, which is convenient for fixing. It is worth mentioning that after fixing the flywheel to the fixing unit, slide the positioning clamp 3 in the opposite direction until it falls off from the top of the worktable 2 and can be removed.

[0040] To further explain, during the process of pushing the placement column 21 to move the bonding plate 26, the protective sleeve 28 will gradually approach and adhere tightly to the outer wall of the flywheel 4. After the small diameter end of the placement column 21 is exposed, it will be engaged in the deformation ring 29, and the bonding plate 26 will continue to push the flywheel 4 to shift. Since the flywheel 4 is only placed at this time and has not been fine-tuned by the staff, some flywheels 4 are still not on the same plane when rotating. At this time, the bonding plate 26 can be used to ensure that the values ​​on the placement columns 21 on both sides of the positioning clip 3 are consistent, thus indicating that the flywheel 4 will not be misaligned when rotating. This operation can be performed after the flywheel 4 is placed, simply by aligning the placement column 21 with the position of the pushing groove 23 and pushing it.

[0041] By setting up a placement column 21, a push plate 22, a push groove 23, an adapter block 24, abutting column 25, and a bonding plate 26, after fixing the flywheel 4, the rotation surface of the flywheel 4 is adjusted. The push of the placement column 21 makes both sides of the flywheel 4 have the same value. So when the flywheel 4 is engaged with the fixing unit, a slight rotation of the flywheel 4 can be used to observe whether there is any deviation during rotation, which effectively improves the efficiency of the worker's adjustment and ensures the progress of drilling the flywheel 4.

[0042] The working principle of the technical solution provided by this invention is as follows: The operator applies a small amount of lubricant to the bottom of the positioning clamp 3, then places the positioning clamp 3 horizontally on top of the workbench 2. Before placing the flywheel 4, the operator can slide the positioning clamp 3 along its outer wall to check for any noticeable vibration during sliding. This also allows the lubricant at the bottom of the positioning clamp 3 to slide to the top of the workbench 2, improving the sliding effect between the workbench 2 and the positioning clamp 3. Next, the operator stops sliding the positioning clamp 3 and places the flywheel 4 in the middle of the positioning clamp 3, ensuring that the bottom of the flywheel 4 is centered between the two positioning clamps 3. Regardless of whether the flywheel 4 is correctly placed in the middle of the two positioning clamps 3, the outer edge of the flywheel 4 should contact the first... After the first force plate 6 is applied, because the weight of the flywheel 4 exceeds the pressure that the first force plate 6 can withstand, the first force plate 6 will deform downwards and move closer to the second force plate 7. The shape of the middle part of the first force plate 6 is "U", so that the flywheel 4 will automatically be in the middle position of the first force plate 6 during the downward placement process. As the flywheel 4 continues to apply pressure to the first force plate 6, the first force plate 6 will continuously move downwards. When the bottom of the first force plate 6 contacts the second force plate 7, it will continue to move downwards along the middle sinking groove 9 of the second force plate 7. When the first force plate 6 presses towards the sinking groove 9, the second force plate 7 will also deform. The deformation of the second force plate 7 will cause the adjusting plates 16 at both ends to move as well. At this time, refer to Figure 6 If the middle of the second force-bearing plate 7 is pressed downwards, both ends of the second force-bearing plate 7 will lift up, from Figure 9 As can be seen, the adjusting plate 16, secured by the adapter 17, the snap-fit ​​post 18, and the lower tensioning plate 19, is pulled upwards as the two ends of the second force plate 7 tilt upwards. Consequently, the rotating column 14 rotates due to the lifting of the adjusting plate 16. During rotation, the limiting buckle 15 gradually approaches and abuts against the middle position of the bottom of the side arc plate 8, thus limiting further rotation of the rotating column 14 and preventing large-angle rotation of the rotating column 14. If the adjusting plate 16 continues to pull upwards after the rotation ends, the upward force will be concentrated on the limiting buckle 15 and the adjusting plate 16. At this time, the lower tensioning plate... The interlocking and pulling effect between the 19 and the upper tension plate 20 becomes more pronounced as the adjusting plate 16 is pulled upwards. In actual operation, the flywheel 4, being heavy, sinks quickly after being placed on the first force plate 6. Pressure gradually transfers from the first force plate 6 to the second force plate 7 and continues along the adjusting plate 16, rotating column 14, and limit buckle 15. Then, the adapter 17 and locking column 18 share some of the pressure. Following this, the bottom of the side arc plate 8 bends upwards. To reduce the appearance of bending creases on the side arc plate 8 after repeated use, which would affect the side... The overall strength of the arc plate 8 is enhanced by a weakening section 13 located in the middle of the side arc plate 8, which actively weakens bending creases. After the worker places the flywheel 4 completely on the first force plate 6, and after a series of pressure transmissions, the bottom of the flywheel 4 rests directly on the placement groove at the top of the side arc plate 8. At this point, the first force plate 6 is in its maximum downward deformation state. The sinking groove 9 in the middle of the second force plate 7 catches the deformed first force plate 6, acting as a buffer. The remaining components, as detailed in the pressure transmission process, are all in normal working condition, thus ensuring the flywheel 4 is properly secured. The flywheel 4 is positioned at the midpoint between the two positioning clips 3, and the outer edge of the bottom of the flywheel 4 will not contact the top of the worktable 2. This prevents the flywheel 4 from sliding normally due to the outer edge of the flywheel 4 hitting the worktable 2 during the subsequent sliding of the positioning clips 3. Finally, the contact block 5 is made of rubber, which allows for greater deformation. When the flywheel 4 is in a stable state, the two contact blocks 5 will also completely adhere to the outer wall of the flywheel 4, limiting the flywheel 4 from the middle position near the flywheel 4. Thus, the flywheel 4 is fixed from the bottom and middle, preventing the flywheel 4 from shaking during the sliding of the positioning clips 3.

[0043] After the flywheel 4 is in place, hold the large-diameter end of the placement post 21 and insert the placement post 21 into the positioning clamp 3 from one side. Align the adapter blocks 24 on the placement post 21 with the slots on the push groove 23 one by one. As mentioned above, the abutment posts 25 and the push plate 22 are arranged in a circular array, while the adapter blocks 24 are arranged in a threaded pattern. During the pushing process, the adapter blocks 24 will contact and press against the abutment posts 25 one by one. Thus, the placement post 21 pushes and drives the adapter blocks 24, and the adapter blocks 24 will slide and squeeze inside the positioning clamp 3. The pressure causes the contact post 25 to slide. After the contact post 25 slides, the traction rope fixed to the contact post 25 is pulled. Then, the sliding of the contact post 25 will squeeze the push plate 22, causing the push plate 22 to slide inside the push groove 23 until the small diameter end of the placement post 21 slides out from inside the push groove 23 and moves towards the middle position of the bonding plate 26. When the small diameter of the placement post 21 does not abut against the deformation ring 29 in the middle position of the bonding plate 26, the bonding plate 26 is fixed by the limiting post 27 being engaged with the positioning clip. 3. Positioned close to the pushing groove 23, so that when the small-diameter end of the placement post 21 has not yet emerged from the pushing groove 23, the bonding plate 26 is snapped and fixed to the side of the positioning clamp 3. After the small-diameter end of the placement post 21 emerges, it will directly abut against the deformation ring 29 in the middle of the bonding plate 26, thereby gradually pushing the limiting post 27 out of the inner wall of the positioning clamp 3. It is worth mentioning that the limiting post 27 will not completely detach from the interior of the positioning clamp 3, ensuring the relative stability of the bonding plate 26, while the small-diameter end of the placement post 21 will continuously approach the deformation ring 29 in the middle of the positioning clamp 3. The deformation ring 29 is squeezed and pressed. Since the inside of the deformation ring 29 is hollow, it is easy for the small diameter end of the placement column 21 to be engaged with the inner wall of the deformation ring 29. When the bonding plate 26 is attached to the surface of the flywheel 4 on the side of the flywheel 4, stop pushing the placement column 21. At this time, observe the value of the large diameter end of the placement column 21. After completing one side of the positioning clip 3, the other side is the same. Finally, slide the entire positioning clip 3 onto the fixing unit and fix it. At this time, due to the limitation of the middle and bottom, the flywheel 4 can move vertically, which is convenient for fixing.
