Description

A tooling for calibrating the accuracy of a tire unloader on a vulcanizing machine Technical Field

[0001] This utility model relates to the field of tire production auxiliary equipment technology, specifically to a tooling for calibrating the accuracy of a vulcanizing machine tire unloader. Background Technology

[0002] After the tire vulcanization process, the tire needs to be transferred to the rear inflatable rim using a tire remover for inflation, shaping, and cooling. The fit and precision between the tire and rim during this process significantly impacts the tire's dynamic mass. If misalignment occurs during inflation, the non-standard state of the tire bead will be carried over to the final product, resulting in poor fit with the rim during subsequent dynamic mass testing and use. As a tire transfer device, the relative precision between the tire remover and the rear inflatable rim determines the tire-rim fit precision; therefore, the precision calibration of the tire remover is crucial.

[0003] During tire transfer, the tire changer undergoes various actions, including turning in, turning out, lowering, raising, and the expansion and contraction of the tire changer's grippers, making it relatively difficult to maintain accuracy. Currently, accuracy measurement often involves using dial indicators and steel tape measures to measure each gripper individually, resulting in numerous measurements and repeated measurements during adjustments, wasting a significant amount of time. Therefore, it is essential to design an auxiliary tooling for accuracy calibration to improve the convenience of accuracy measurement and reduce labor intensity. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a tooling for calibrating the accuracy of a tire unloader on a vulcanizing machine.

[0005] The technical solution of this utility model is: a precision calibration fixture for a vulcanizing machine tire unloader, including a mating seat, a lifting platform, a fixed rod, a fixed platform, and a measuring arm assembly. The mating seat is adapted to the main shaft of the rear pneumatic wheel rim, and a support seat is fixed on its top. The support seat is provided with multiple vertical guide rods. The lifting platform is slidably connected to the multiple guide rods, and its top is fixedly connected to the fixed platform through multiple fixed rods. It is also connected to the support seat through a lifting mechanism.

[0006] Multiple sets of the aforementioned measuring arm assemblies are radially mounted in a circumferential array on the outer wall of the mating seat, and each corresponds one-to-one with the tire changer gripper. Each measuring arm assembly includes a mounting platform, a sliding rod, a compression spring, a connecting rope, and a reversing assembly for reversing the connecting rope. The mounting platform is horizontally fixed to the outer wall of the mating seat, and a support housing is fixed to the mounting platform. The sliding rod slides through the outer end plate of the support housing, and the compression spring is located inside the support housing, with its two ends connected to the inner end of the sliding rod and the inner wall of the inner end plate of the support housing, respectively. The reversing assembly is fixed to the outer wall of the mating seat and located between the support housing and the outer wall of the mating seat. The connecting rope passes around the reversing assembly, with one end connected to the inner end of the sliding rod and the other end fixed to the fixed platform.

[0007] Preferably, the lifting mechanism includes a rotating screw coaxially arranged with the mating seat. The rotating screw vertically passes through the center of the fixed platform and the lifting platform. Its upper end is connected to a handle, its lower end is rotatably connected to the support seat, and it is threadedly connected to the lifting platform.

[0008] Preferably, there are two guide rods, which are symmetrically arranged with the rotating lead screw as the center.

[0009] Preferably, there are two fixing rods, which are symmetrically arranged with the rotating lead screw as the center.

[0010] Preferably, the reversing assembly includes two guide wheels, one of which is mounted on the mounting platform and the other is mounted on the outer wall of the mating seat below the mounting platform.

[0011] Preferably, the supporting shell is a square shell.

[0012] Preferably, the mating seat is a cylindrical body.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This fixture features a novel structure and is easy to use. Through the synchronous operation of multiple sets of measuring arm components, it can achieve rapid and accurate measurement, thus improving the convenience of accuracy measurement.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Embodiment 1

[0019] Referring to Figures 1-2, a precision calibration fixture for a vulcanizing machine tire unloader includes a mating base 1, a lifting platform 4, fixed rods 5, a fixed platform 6, and a measuring arm assembly. The mating base 1 is a cylindrical body that is adapted to the main shaft of the rear inflatable wheel rim, and a support base 2 is fixed on its top. Two vertical guide rods 3 are provided on the support base 2. The lifting platform 4 is slidably connected to the two guide rods 3, and its top is fixedly connected to the fixed platform 6 through two fixed rods 5. The platform 4 is also connected to the support base 2 through a lifting mechanism.

[0020] Multiple measuring arm assemblies are radially mounted in a circumferential array on the outer wall of the mating base 1, corresponding one-to-one with the tire changer grippers. Each measuring arm assembly includes a mounting platform 9, a sliding rod 11, a compression spring 12, a connecting rope 13, and a reversing assembly for reversing the connecting rope 13. The mounting platform 9 is horizontally fixed to the outer wall of the mating base 1, and a support housing 10 is fixed on the mounting platform 9. The sliding rod 11 slides through the outer end plate of the support housing 10. The compression spring 12 is located inside the support housing 10, with its two ends connected to the inner end of the sliding rod 11 and the inner wall of the inner end plate of the support housing, respectively. The reversing assembly is fixed to the outer wall of the mating base 1 and is located between the support housing 10 and the outer wall of the mating base 1. The connecting rope 13 passes around the reversing assembly, with one end connected to the inner end of the sliding rod 11 and the other end fixed to the fixed platform 6. Specifically, the support housing 10 is a square housing.

[0021] Under the action of the compression spring 12, the connecting rope 13 is always in a taut state. When the fixed platform 6 rises, the connecting rope 13 pulls the sliding rod 11 to retract; when the fixed platform 6 descends, the connecting rope 13 extends the sliding rod 11.

[0022] More specifically, the reversing assembly includes two guide wheels 14, one of which is mounted on the mounting platform 9 and the other is mounted on the outer wall of the mating seat 1 below the mounting platform 9; the connecting rope 13 is led out from the inner end of the sliding rod 11, passes around the two guide wheels 14 in sequence, changes from horizontal to vertical, and finally connects to the fixed platform 6.

[0023] In use, rotate the tire changer to above the main shaft of the rear inflator rim and adjust the descent height to the accuracy verification position; lift the lifting platform 4 and the fixed platform 6 through the lifting mechanism, and then fit the mating seat 1 onto the main shaft of the rear inflator rim; then lift the fixed platform 6 through the lifting mechanism to descend. At this time, multiple sliding rods 11 extend outward synchronously under the push of the compression spring 12 until one of the sliding rods 11 contacts the gripper. Visually select the gripper farthest from the sliding rod 11 for distance measurement, and the accuracy measurement is completed.

[0024] Next, adjust the position of the tire changer: adjust the position of the tire changer by adjusting the swing limit screw and the telescopic adjuster, and fine-tune the extension of the sliding rod 11 until the distance between each gripper of the tire changer and the sliding rod 11 is consistent. Finally, remove this fixture.

[0025] This fixture features a novel structure and is easy to use. The synchronized operation of multiple measuring arm assemblies enables rapid and accurate measurements, enhancing the convenience of precision measurement. This fixture also assists in adjusting the position of the tire changer, allowing for continuous monitoring of position changes during adjustment and avoiding repeated measurements. Example 2

[0027] Referring to Figure 1, the lifting mechanism includes a rotating screw 7 coaxially arranged with the mating seat 1. The rotating screw 7 vertically passes through the center of the fixed platform 6 and the lifting platform 4. Its upper end is connected to a handle 8, its lower end is rotatably connected to the support seat 2, and is threadedly connected to the lifting platform 4.

[0028] More specifically, the two guide rods 3 and the two fixed rods 5 are symmetrically arranged with the rotating lead screw 7 as the center.

[0029] In use, the lifting platform 4 moves up and down along the guide rod 3 by rotating the screw 7 by turning the handle 8.

[0030] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
