[0004] Existing riveting pressure spring end grinding devices mostly use single or simple clamps to fix the spring, which is difficult to adapt to different specifications, has poor fixing effect, and the spring is prone to displacement during grinding, resulting in reduced grinding accuracy and affecting product quality. It may also damage the equipment due to shaking and collision, increasing maintenance costs and reducing production efficiency. Furthermore, traditional grinding mechanisms are mostly manually adjustable or rely on simple slide rails for movement, lacking precise drive and limit. Manual adjustment cannot ensure accurate positioning, and simple slide rails are prone to shaking and displacement, making it impossible to flexibly adjust the grinding position and stroke. This makes it difficult to meet diverse production needs, has poor versatility, and limits its application. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 4 As shown, this utility model provides a device for grinding the end of a riveted pressure spring, including a base plate 1, an adjusting frame 3 fixedly mounted on the upper surface of the base plate 1, a support rod 11 fixedly mounted on the upper side of the base plate 1, an upper plate 12 fixedly mounted on the upper end of the support rod 11, a support block 2 fixedly mounted on the upper surface of the upper plate 12, a vertical rod 21 fixedly mounted on one side of the upper surface of the support block 2, a threaded rod 22 threadedly connected to the upper surface of the vertical rod 21, a rotating post 23 fixedly mounted on the upper end of the threaded rod 22, a rotating handle 24 fixedly mounted through the outer surface of the rotating post 23, an upper pressure block 25 rotatably connected to the lower end of the rotating post 23, and a fixed upper pressure block 25 on the upper surface of the support block 2. The lower locking block 26 and the base plate 1 serve as the basic support structure for the entire device, providing a stable mounting surface for components such as the adjustment frame 3 and the support rod 11. The support rod 11 and the upper plate 12 form the upper support structure for mounting the support block 2. The lower locking block 26 on the support block 2 can initially position the bottom of the pressure spring. When the handle 24 is turned, the rotating column 23 and the screw 22 are rotated. Since the screw 22 is threadedly connected to the upright 21, the screw 22 will move up and down along the upright 21, thereby driving the upper pressure block 25 at the lower end of the rotating column 23 to move, thereby clamping and fixing the pressure spring and ensuring that the spring remains stable during the grinding process.
[0023] Specifically, the inner rotating part of the adjusting frame 3 is provided with a lead screw 31. A servo motor 32 is fixedly mounted on one side of the adjusting frame 3, and the output end of the servo motor 32 passes through the adjusting frame 3 and is fixedly connected to the lead screw 31. A moving block 33 is threaded on the outer surface of the lead screw 31, and an indirect plate 34 is fixedly connected to the upper side of the moving block 33. A bracket 35 is detachably connected to the upper side of the indirect plate 34. A DC motor 4 is fixedly mounted on one side of the bracket 35, and the output end of the DC motor 4 passes through the bracket 35 and is fixedly connected to a mounting shaft 41. A mounting shaft 41 is detachably connected to one side of the mounting shaft 41. After the servo motor 32 starts, its output end drives the lead screw 31 to rotate. Since the moving block 33 is threadedly engaged with the lead screw 31, the rotation of the lead screw 31 will cause the moving block 33 to move in the adjustment frame 3 along the axial direction of the lead screw 31. The moving block 33 drives the bracket 35 to move through the indirect plate 34, thereby adjusting the position of the DC motor 4, the mounting shaft 41 and the grinding disc 42 mounted on the bracket 35. After the DC motor 4 starts, its output end drives the mounting shaft 41 to rotate, thereby causing the grinding disc 42 to rotate at high speed and grind the end of the pressure spring.
[0024] Furthermore, connecting blocks 43 are fixedly provided on the outer surfaces of both the mounting shaft 41 and the grinding disc 42, and the corresponding two connecting blocks 43 are connected by bolts. By setting connecting blocks 43 on the outer surfaces of the mounting shaft 41 and the grinding disc 42, and fixing the corresponding connecting blocks 43 with bolts, the mounting shaft 41 and the grinding disc 42 are detachably connected. When the grinding disc 42 is worn, the bolts can be easily unscrewed, the old grinding disc 42 can be removed, and a new grinding disc 42 can be installed, which facilitates equipment maintenance and replacement of the grinding disc 42.
[0025] Furthermore, a limiting plate 28 is movably fitted at the lower end of the rotating column 23, and a positioning post 29 is fixedly provided on one side of the lower surface of the limiting plate 28. The positioning post 29 passes through the upright 21 and is fixedly connected to the upper pressure block 25. The limiting plate 28 is fitted at the lower end of the rotating column 23 and cooperates with the positioning post 29 to limit the movement range and direction of the upper pressure block 25. When the rotating column 23 drives the upper pressure block 25 to move up and down, the positioning post 29 moves within the upright 21 to ensure that the upper pressure block 25 can only move in the vertical direction, preventing the upper pressure block 25 from shifting or rotating during the movement, thereby ensuring the accuracy and stability of clamping the pressure spring.
[0026] It is worth noting that a limiting post 36 is fixedly provided inside the adjusting frame 3, and the limiting post 36 passes through the moving block 33. The limiting post 36 passes through the moving block 33, providing guidance and limiting function for the movement of the moving block 33 within the adjusting frame 3. When the servo motor 32 drives the lead screw 31 to rotate, and the moving block 33 moves along the lead screw 31, the limiting post 36 restricts the moving block 33 to move only along the axial direction of the lead screw 31, preventing the moving block 33 from shaking or deviating during the movement, and ensuring the smoothness and accuracy of the grinding mechanism's movement.
[0027] It is worth noting that one side of the bracket 35 is clipped onto the indirect plate 34, and the indirect plate 34 and the bracket 35 are connected by bolts. After the bracket 35 is initially positioned by clipping into the indirect plate 34, the indirect plate 34 and the bracket 35 are fixedly connected by bolts. This connection method allows the bracket 35 to be stably installed on the indirect plate 34. At the same time, when it is necessary to disassemble, repair or adjust the grinding mechanism, the bolts can be easily unscrewed and the bracket 35 can be disassembled, which facilitates the maintenance and debugging of the equipment.
[0028] It is worth mentioning that a limiting strip 37 is symmetrically fixed on one side of the indirect plate 34, and the limiting strip 37 is locked on the adjustment frame 3. The limiting strip 37 on the indirect plate 34 is locked on the adjustment frame 3, which further enhances the stability of the indirect plate 34 when it moves within the adjustment frame 3. When the moving block 33 drives the indirect plate 34 to move, the cooperation between the limiting strip 37 and the adjustment frame 3 restricts the direction of movement of the indirect plate 34, prevents the indirect plate 34 from shifting laterally during the movement, and ensures that the grinding mechanism installed on the indirect plate 34 can move accurately and smoothly to the target position for grinding.
[0029] The servo motor 32 and DC motor 4 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.
[0030] Working principle: First, place the riveted pressure spring to be ground on the support block 2. Use the lower clamping block 26 to initially fix the bottom of the spring. By turning the handle 24, the rotating column 23 is driven to rotate. Since the threaded column 22 is connected to the upright 21 by thread, the rotating column 23 will move up and down along the upright 21 when it rotates, thereby pushing the upper pressure block 25 to move down. Together with the lower clamping block 26, the spring is firmly clamped and fixed, ensuring that the spring will not shake during the grinding process.
[0031] After the spring is fixed, the servo motor 32 is started, and its output end drives the lead screw 31 to rotate. Since the moving block 33 is threaded on the outer surface of the lead screw 31, the rotation of the lead screw 31 will cause the moving block 33 to move in the adjustment frame 3 along the direction of the lead screw 31. At the same time, the limiting post 36 passes through the moving block 33, which guides and limits the movement of the moving block 33, ensuring that the moving block 33 moves smoothly. The moving block 33 drives the bracket 35 to move through the indirect plate 34. The limiting strip 37 on one side of the indirect plate 34 is locked on the adjustment frame 3, further ensuring the stability of the movement.
[0032] Once the grinding mechanism is moved to the appropriate position, the DC motor 4 is started. Its output end drives the mounting shaft 41 to rotate, which in turn drives the grinding disc 42 to rotate at high speed. The grinding disc 42 grinds the end of the spring by contacting it, thus achieving a smoothing operation. Since the mounting shaft 41 and the grinding disc 42 are detachably connected by the connecting block 43 and bolts, it is convenient to replace the grinding disc 42 after it wears out.
