Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bushing installation technology, specifically relating to a pressing device for spring leaf bushing of a non-pneumatic tire lateral stop component. Background Technology
[0002] Lateral stop components are key parts of non-pneumatic tires, and their main functions are: 1. Positioning: to counteract the lateral shear load generated during tire operation and ensure smooth vehicle operation; 2. Structural constraint: to limit misalignment between the inner and outer rims by connecting them. With the iterative upgrades of non-pneumatic tire products, the structure of lateral stop components has evolved from a rigid structure that only met basic functions to a spring-plate structure that integrates buffering and shock absorption functions. For details on the specific spring-plate structure, please refer to Chinese Utility Model Patent 202421954411.X.
[0003] The bushing is a key component in the molding of the leaf spring assembly, and currently, it is still installed manually by hammering. This traditional assembly method has the following significant drawbacks: First, the assembly efficiency is low, with each piece taking 15-20 minutes, and the leaf spring assembly will vary in size and specifications due to different tire models; second, the hammering process easily causes bushing deformation, resulting in a finished product qualification rate of only 80%; and third, it is labor-intensive.

[0042] A pressing device for spring bushing of a non-pneumatic tire lateral stop member, comprising:
[0043] Bottom platform 2;
[0044] The bushing mounting positioning plate 9 is disassembled and installed on the bottom platform 2 with a gap to form an installation space for placing the spring sheet through the gap. The bushing mounting positioning plate 9 is provided with bushing mounting positioning holes 10 corresponding to the shaft holes at both ends of the spring sheet.
[0045] Clamping blocks are provided on both sides and both ends of the gap to clamp the two sides and both ends of the spring sheet;
[0046] The pressing platform 1 is located above the bushing mounting and positioning plate 9, and moves vertically up and down via the pressing drive mechanism 4;
[0047] Two bushing pressure shafts 6 are positioned below the lower pressure platform 1 and move relative to each other along the line connecting the shaft holes at both ends of the spring sheet.
[0048] The bushing mounting positioning plate 9 features a detachable design, allowing for the replacement of different bushing mounting positioning plates 9 to accommodate spring sheets with varying hole spacings, thus matching different vehicle tire sizes. Furthermore, the bushing pressure shaft 6 employs an adjustable spacing design, enabling lateral displacement along the line connecting the two ends of the spring sheet's shaft holes. This ensures that even after replacement, the bushing mounting positioning plate 9 can still be adjusted to firmly press the bushing into the two ends of the spring sheet's shaft holes.
[0049] The clamping block plays a clamping and positioning role in the above process to ensure that no displacement occurs during the pressing process. To further improve the clamping effect, in some embodiments, the clamping block includes:
[0050] Two side clamps 11 are provided on both sides of the gap, and the inner end face of the side clamps 11 is a planar structure with a straight line structure.
[0051] Two end clamps 12 are provided at both ends of the gap, and the inner end face of the end clamps 12 is an arc-shaped structure with an inner groove.
[0052] Here, taking into account the external structural features of the spring sheet—that is, the spring sheet is a cuboid structure with arc-shaped ends—the end clamping block 12 is configured with an arc-shaped structure resembling an inner groove to ensure a close clamping fit, while the side clamping block 11 is configured with a straight planar structure resembling a straight line to secure it. These features ensure stability during the clamping process.
[0053] In some embodiments, it also includes:
[0054] The pressure shaft adjustment slide rail 7 is located below the pressure platform 1;
[0055] The bushing pressure shaft slider is located above the bushing pressure shaft 6 and is slidably connected to the pressure shaft adjusting slide rail 7;
[0056] The pressure shaft adjusting screw 8 is rotatably mounted on one side of the bushing pressure shaft slider and is threadedly connected to the bushing pressure shaft slider.
[0057] The above-described structural method is a specific adjustment method for the bushing pressure shaft 6 during the displacement process. It utilizes the screw principle to make the adjustment more precise and ensure the accuracy of the bushing pressure shaft 6 during the pressing process.
[0058] Furthermore, the bushing pressure shaft slider has sliding protrusions on both sides, which are engaged in the grooves of the pressure shaft adjusting slide rail 7. This makes the adjustment process more stable and reliable.
[0059] In some embodiments, it also includes:
[0060] The clamping block slide rail 13 is disposed on the bottom platform 2 and slidably connected to the clamping block;
[0061] The limiting baffle 14 is provided at the outer end of the clamping block slide rail 13 and has a through hole;
[0062] The clamping and adjusting screw 15 passes through the limiting baffle 14 and is threadedly connected to the limiting baffle 14. The inner end of the clamping and adjusting screw 15 is rotatably connected to the clamping block.
[0063] The above-described structure is a method of clamping and fixing multiple spring plates after they are stacked. Since installation space is required when placing multiple spring plates, they are usually inserted through the side. Therefore, the process of moving the clamping block outward needs to be as simple and efficient as possible while ensuring the clamping effect. Thus, the threaded structure principle is used to achieve quick unlocking or tightening.
[0064] In some embodiments, it also includes:
[0065] The top platform 3 is located above the pressing platform 1, and the pressing drive mechanism 4 is installed on the lower end face of the top platform 3.
[0066] The guide shaft 5 is located between the top platform 3 and the bottom platform 2, and extends through the pressing platform 1.
[0067] Specifically, the downward driving mechanism 4 is installed at the geometric center between the downward platform 1, the bottom platform 2, and the top platform 3, and four guide shafts 5 are symmetrically arranged along the geometric center.
[0068] In some embodiments, the clamping block has sliding protrusions on both sides, which are engaged in the grooves of the clamping block slide rail 13.
[0069] In some embodiments, the two side clamps 11 and the two end clamps 12 are arranged in a cross-shaped structure.
[0070] In some embodiments, it also includes:
[0071] A handle is provided on the bottom platform 2.
[0072] By adopting the above-mentioned structural layout, the overall structure becomes more compact, rational, and reliable, thereby improving the reliability of the equipment.
[0073] Its working principle is as follows:
[0074] Select the appropriate bushing mounting positioning plate 9 according to the spring sheet to be installed, and install it above the bottom platform 2, while ensuring that there is a gap between it and the bottom platform 2 to provide space for the spring sheet. The installation and disassembly method can be to set connecting shafts at the four corners and use nuts to fix the connection to achieve the disassembly function.
[0075] After selecting and installing the bushing mounting positioning plate 9, place the neatly stacked spring sheets in the gaps. Then, clamp and position the spring sheets using the side clamping block 11 and the end clamping block 12, locking them with a threaded structure. The inner end face of the end clamping block 12 has an inwardly grooved arc structure to improve the stability and reliability of the clamping. Adjust the threads to align and clamp the spring sheets, ensuring that the shaft holes at both ends of the spring sheets are aligned with the bushing mounting positioning holes 10. Then, place the bushing in the bushing mounting positioning hole 10 and adjust the position of the two upper bushing pressure shafts 6. Then, drive the downward pressing mechanism 4 to move the bushing pressure shafts 6 downward and make contact with the bushing, finally pressing the bushing into the shaft holes at both ends of the corresponding spring sheet to complete the entire installation operation.
[0076] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
