Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a tooling for a wheel rim flange on a tire drum testing machine. Background Technology

[0002] In the field of tire performance testing, the tire drum testing machine is a core piece of equipment used to evaluate key indicators such as tire high-speed performance and durability. In traditional technical solutions, to ensure testing accuracy and safety, the industry generally uses custom-made forged steel rims as test rims. These forged steel rims are connected to the testing machine via a dedicated workstation shaft. The installation dimensions of the shaft end flange are perfectly matched with the design parameters of the workstation shaft. The forged steel rims need to be custom-made; the unit price is high, and the production cycle is long; the rims are heavy and cannot be moved by one person, requiring two people to lift them, posing a risk of injury to operators such as crushing or twisting injuries.

[0003] With the development of the automotive industry, commercial vehicles commonly use aluminum alloy rims. These rims differ significantly from the custom-made forged steel rims of the testing machine in terms of size specifications, center hole design, and especially bolt hole pitch circle diameter (PCD). The existing testing machine station shafts cannot directly install commercially available aluminum alloy rims.

[0004] If it is necessary to test tires equipped with commercial aluminum alloy rims, it is necessary to customize expensive special forged steel rims. This not only significantly increases the testing cost and cycle, but may also introduce additional testing variables due to the different stiffness, mass and other parameters of the rims themselves, affecting the accuracy and comparability of the test data. Secondly, it greatly limits the flexibility and efficiency of the test, and cannot quickly respond to the market's testing needs for tires with various specifications of aluminum alloy rims. Utility Model Content

[0005] In view of the problem that the existing tire drum testing machine cannot be adapted to install commercial aluminum alloy rims, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a flange fixture for the wheel rim of a tire drum testing machine, the purpose of which is to enable the tire drum testing machine to be adapted to install commercial aluminum alloy wheel rims through the flange fixture.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a tire drum testing machine workstation shaft rim flange fixture, including a first disc and a second disc, wherein a ring of first discs is welded at equal intervals on the outer edge of the opposite surfaces of the first disc and the second disc, and an equal interval adjustment component is installed on one end face of the first disc near the second disc, wherein each of the five movable ends of the equal interval adjustment component is equipped with a smooth rod bolt, and five movable channels for the smooth rod bolts to pass through and move are opened on the second disc;

[0008] The equal-space adjustment assembly includes a circular rack rotatably mounted on a first disk and five threaded transmission structures arranged in a circle, with the circular rack driving the threaded transmission structures to operate.

[0009] As an improved technical solution, a fixing hole is provided on the top of the first disk and between two adjacent arc-shaped connecting blocks.

[0010] As an improved technical solution, a groove is provided at one end of the first disk near the guide rod bolt, a bearing is fixed inside the groove, and a circular rack is rotatably mounted on the first disk through the bearing.

[0011] As an improved technical solution, the peripheral surface of the circular rack is welded with multiple protrusions at intervals, and the outer end of the protrusion is 1 cm away from the inner wall surface of the arc-shaped connecting block.

[0012] As an improved technical solution, the threaded transmission structure includes a shaft block fixed on a first disc, a lead screw rotatably mounted on the shaft block, a transmission gear meshing with the circular rack at one end of the lead screw near the rack, a transmission block threadedly mounted on the other end of the lead screw, and the transmission block being laterally slidably mounted on the first disc, while the top of the transmission block is detachably mounted on a smooth rod bolt.

[0013] As an improved technical solution, a circular block is fixed on the top of the transmission block, and a threaded rod is coaxially welded to one end of the circular block near the smooth rod bolt. A threaded recess is provided at one end of the smooth rod bolt near the circular block for threaded connection with the threaded rod.

[0014] As an improved technical solution, the threaded transmission structure further includes a guide rail fixed on the first disc, a groove is provided at the bottom of the transmission block, and the transmission block is slidably connected to the guide rail through the groove.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a wheel rim flange fixture for a tire drum testing machine. This wheel rim flange fixture for a tire drum testing machine includes a first disc 1 and a second disc 3, and a circular hole is provided at the center of the first disc 1 and the second disc 3. A ring of first disc 1 is welded at equal intervals on the outer edge of the opposite face of the first disc 1 and the second disc 3. An equal interval adjustment component 6 is installed on one end face of the first disc 1 near the second disc 3. Each of the five movable ends of the equal interval adjustment component 6 is equipped with a smooth rod bolt 5, and five movable channels 4 are provided on the second disc 3 for the smooth rod bolt 5 to pass through and move.

[0027] The equal spacing adjustment assembly 6 includes a circular rack 8 rotatably mounted on the first disk 1, and five threaded transmission structures 9 arranged in a circle, wherein the circular rack 8 drives the threaded transmission structures 9 to work.

[0028] Fixing holes 7 are provided on the top of the first disc 1 and between the two adjacent arc-shaped connecting blocks 2.

[0029] A groove 10 is provided at one end of the first disc 1 near the guide bolt 5. A bearing 11 is fixed inside the groove 10, and a circular rack 8 is rotatably mounted on the first disc 1 through the bearing 11.

[0030] The peripheral surface of the circular rack 8 is welded with multiple protruding rods 12 at intervals, and the outer end of the protruding rod 12 is 1 cm away from the inner wall of the arc-shaped connecting block 2. The protruding rods 12 provide a better force application point and make it easier for the operator to drive the circular rack 8 to rotate.

[0031] The threaded transmission structure 9 includes a shaft block 91 fixed on the first disc 1, a lead screw 96 rotatably mounted on the shaft block 91, a transmission gear 97 meshing with the circular rack 8 at one end of the lead screw 96 near the rack 8, an internal hexagonal groove at one end of the lead screw 96 near the transmission gear 97, and a transmission block 94 threadedly mounted on the other end of the lead screw 96. The transmission block 94 is laterally slidably mounted on the first disc 1, and the top of the transmission block 94 is detachably mounted on the smooth rod bolt 5.

[0032] The threaded transmission structure 9 also includes a guide rail 92 fixed on the first disc 1, a groove 93 is provided at the bottom of the transmission block 94, and the transmission block 94 is slidably connected to the guide rail 92 through the groove 93. A threaded hole 95 is provided on one side of the transmission block 94 for threaded connection with the lead screw 96.

[0033] During use, the meshing transmission of the circular rack 8 and the transmission gear 97 causes multiple lead screws 96 to rotate synchronously. Under the threaded transmission of the lead screws 96 and the threaded holes 95 on the transmission block 94, the transmission block 94 is driven to move laterally along the guide rail 92, which in turn drives the polished rod bolts 5 to move along the inside of the movable channel 4. This allows for simultaneous adjustment of the positions of the five polished rod bolts 5, enabling the adjustment of the PCD size to fit commercial wheel hubs. The spacing between the five polished rod bolts 5 can be freely adjusted to a certain extent, making it suitable not only for commercial wheel hubs but also for different models of commercial wheel hubs, thus improving the adaptability and flexibility of commercial wheel hubs.

[0034] Example 2

[0035] Reference Figures 2-3This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a circular block 13 is fixed on the top of the transmission block 94, and a threaded rod is coaxially welded to one end of the circular block 13 near the smooth rod bolt 5. A threaded concave hole is opened at one end of the smooth rod bolt 5 near the circular block 13 to be threadedly connected to the threaded rod.

[0036] During use, the smooth rod bolt 5 is detachably installed on the circular block 13 through the threaded connection between the threaded rod and the threaded concave hole. The smooth rod bolt 5 can be replaced according to different commercial wheel hubs to ensure consistency. It not only adapts to different commercial wheel hubs, but also improves the firmness of fixing the commercial wheel hubs.

[0037] The remaining structure is the same as that in Example 1.

[0038] Based on embodiments 1-2, the working principle of this utility model is as follows: After the fixing bolt on the tire drum testing machine passes through the fixing hole 7, a hexagonal nut is screwed on it to fix the tooling to the tire drum testing machine. After the smooth bolt 5 passes through the fixing hole on the commercial wheel hub, a locking nut is installed on the smooth bolt 5 to realize the installation between the commercial wheel hub and the tire drum testing machine.

[0039] The process for adjusting the PCD dimensions formed by the five smooth bolts 5 is as follows:

[0040] The circular rack 8 is driven to rotate by the protruding rod 12. Under the meshing transmission action of the circular rack 8 and the transmission gear 97, multiple lead screws 96 rotate synchronously. Under the threaded transmission action of the lead screw 96 and the threaded hole 95 on the transmission block 94, the transmission block 94 is driven to move laterally along the direction of the guide rail 92, that is, to drive the polished rod bolt 5 to move along the direction inside the movable channel 4. The position of the five polished rod bolts 5 can be adjusted at the same time to realize the adjustment of the PCD size and adapt to commercial wheel hubs.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
