Description

Technical Field

[0001] This utility model relates to the field of leaf spring technology, and in particular to a grinding device for leaf spring production. Background Technology

[0002] Leaf springs, also known as leaf springs, are elastic elements made of multiple curved metal plates of unequal lengths stacked together. They are widely used in suspension systems of automobiles, construction machinery, railway vehicles, and other fields, and are mainly used to bear loads, buffer impacts, transmit forces, and maintain wheel alignment.

[0003] Patent CN221755584U discloses a steel leaf spring grinding device. It includes a first base fixedly mounted on a base plate, a slide block and a first limiting plate respectively fixedly mounted on the first base, with the first limiting plate located behind the slide block. A slider is slidably mounted inside the slide block, and the slider has threaded holes penetrating both sides. A first lead screw is threadedly connected to the slider through these threaded holes. Using this patent, rotating the third lead screw drives the fixing blocks to clamp the steel leaf spring onto the second limiting plate. Then, controlling the second motor merges the second base with the first base, driving the grinding motor and controlling the grinding wheel to rotate for grinding. However, when the aforementioned prior art uses two fixing blocks to move inward and clamp the steel leaf spring, the two fixing blocks will squeeze the steel leaf spring. Excessive pressure can easily cause local deformation and damage to the steel leaf spring, and can easily cause surface damage and micro-cracks at the clamping point.

[0004] Therefore, there is a need for a grinding device for producing flexible clamping leaf springs. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, which use two fixed blocks to clamp the leaf spring inward, the two fixed blocks will squeeze the leaf spring, and the excessive pressure will easily cause local deformation and crushing of the leaf spring, and cause surface damage and micro-cracks at the clamping point, this utility model provides a flexible clamping grinding device for leaf spring production.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a grinding device for producing steel leaf springs, comprising a support base, an electric guide rail, a slide block, a mounting base, a grinding wheel, elastic elements, and a servo motor. The support base is equipped with an electric guide rail, and the electric slider of the electric guide rail is equipped with a slide block. A mounting base is slidably mounted on the slide block. Two elastic elements are fitted onto the mounting base, with both ends of the elastic elements connected to the slide block and the mounting base respectively. A servo motor is mounted on the mounting base, and a grinding wheel is mounted on the output shaft of the servo motor. The device also includes an air tank, a connecting pipe, an air bladder, and an air pump. Two air tanks are fixedly connected to the support base, an air bladder is mounted on the support base, and an air pump is mounted on the air tanks. A connecting pipe connects the air pump to the air bladder.

[0007] As an improvement to the above solution, it also includes a fixed plate, a guide rod, a screw, a dual-axis motor, and a limit plate. Two fixed plates are fixedly connected to the support base, and guide rods are fixedly connected to the two fixed plates. A dual-axis motor is installed on the support base, and screws are installed on the two output shafts of the dual-axis motor through couplings. The two screws rotate on the other two fixed plates, and limit plates are threaded on the screws.

[0008] As an improvement to the above solution, it also includes a mounting plate, a lead screw, and a positioning plate. Two mounting plates are fixedly connected to the support base, and a lead screw is threaded onto the mounting plate. A positioning plate is fixedly connected to the lead screw.

[0009] As an improvement to the above solution, a handwheel is fixedly connected to the lead screw.

[0010] As an improvement to the above solution, four triangular reinforcing ribs are fixedly connected to the support base.

[0011] As an improvement to the above solution, two guides are fixedly connected to the positioning plate.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By using an air pump to draw gas from the gas storage tank into the air bag through the connecting pipe, the air bag wraps around the steel leaf spring, thereby adapting to steel leaf springs of different curvatures and thicknesses, thus preventing the steel leaf spring from shifting position during grinding.

[0013] 2. By starting the dual-axis motor, the dual-axis motor synchronously drives the screws on both sides to rotate, causing the two limiting plates to move towards each other along the guide rod. By adjusting the distance between the limiting plates, the steel leaf springs of different widths can be adapted to be limited in front and behind.

[0014] 3. By rotating the lead screws on both sides of the handwheel, the lead screws drive the positioning plate to move inward, thereby limiting the left and right movement of the steel leaf spring and ensuring that the workpiece remains stable during the grinding process.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Example 1: A grinding device for producing leaf springs, see reference. Figures 1-5 As shown, the device includes a support base 1, an electric guide rail 2, a slide block 3, a mounting base 4, a grinding wheel 5, elastic elements 6, and a servo motor 7. The electric guide rail 2 is bolted to the upper part of the support base 1. The slide block 3 is mounted on the electric slider of the electric guide rail 2. The mounting base 4 is slidably mounted on the slide block 3. Two elastic elements 6 are fitted on the mounting base 4. The two ends of the elastic elements 6 are connected to the slide block 3 and the mounting base 4, respectively. The servo motor 7 is bolted to the lower front side of the mounting base 4. The grinding wheel 5 is mounted on the output shaft of the servo motor 7 and rotates on the mounting base 4. The device also includes an air tank 8, a connecting pipe 9, an air bladder 10, and an air pump 11. The air tank 8 is symmetrically fixed to the lower part of the support base 1. The air bladder 10 is mounted on the support base 1 and is located below the grinding wheel 5. The air pump 11 is mounted on the air tank 8, and the connecting pipe 9 connects the air pump 11 and the air bladder 10.

[0023] See Figures 1-5 As shown, four triangular reinforcing ribs are fixedly connected to the support base 1.

[0024] When using this device, place the leaf spring on the airbag 10. The air pump 11 draws gas from the air tank 8 into the airbag 10 through the connecting pipe 9, so that the airbag 10 encloses the leaf spring. This allows it to adapt to leaf springs of different curvatures and thicknesses, thus preventing the leaf spring from shifting position during grinding. After fixing, start the electric guide rail 2 and the servo motor 7. The electric guide rail 2 drives the electric slider on itself to move the slide block 3 horizontally. The slide block 3 drives the mounting base 4 and the grinding wheel 5 to feed laterally. The mounting base 4 is floatingly connected to the slide block 3 through the elastic element 6, so that the grinding wheel 5 can adapt to the surface undulations of the leaf spring during grinding and maintain constant pressure. At the same time, the servo motor 7 drives the grinding wheel 5 to rotate at high speed to grind the leaf spring.

[0025] Example 2: Based on Example 1, refer to Figure 2 , Figure 4 and Figure 5 As shown, it also includes a fixed plate 12, a guide rod 13, a screw 14, a dual-axis motor 15, and a limiting plate 16. The left and right sides of the support base 1 are equipped with fixed plates 12 by welding. The guide rods 13 are fixedly connected to the two fixed plates 12 on the left. The dual-axis motor 15 is installed on the support base 1 by bolt connection. The two output shafts of the dual-axis motor 15 are equipped with screws 14 by couplings. The screws 14 rotate on the fixed plate 12 on the right. The screws 14 are threaded with a limiting plate 16, which slides on the guide rods 13.

[0026] See Figure 1 and Figure 5 As shown, it also includes a mounting plate 17, a lead screw 18, and a positioning plate 19. The support base 1 has mounting plates 17 welded on both the left and right sides. The mounting plate 17 is threaded with a lead screw 18, and the positioning plate 19 is fixedly connected to the inner end of the lead screw 18.

[0027] See Figure 1 and Figure 5 As shown, a handwheel is fixedly connected to the outer end of the lead screw 18.

[0028] See Figure 1 and Figure 5 As shown, two guide plates are fixedly connected to the positioning plate 19, and the guide plates slide on the mounting plate 17.

[0029] When the leaf spring is placed on the airbag 10, the dual-axis motor 15 is started, and the dual-axis motor 15 synchronously drives the screws 14 on both sides to rotate, so that the two limiting plates 16 move towards each other along the guide rod 13. By adjusting the distance between the limiting plates 16 to accommodate leaf springs of different widths, the leaf spring can be limited in front and back. Then, by turning the handwheel to rotate the lead screws 18 on both sides, the lead screws 18 drive the positioning plate 19 to move inward, thereby limiting the leaf spring in the left and right directions and ensuring that the workpiece remains stable during the grinding process.

[0030] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
