Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically to a wheel hub unit bench testing equipment. Background Technology

[0002] During the wheel manufacturing process, to ensure that the product quality meets usage requirements, the wheel must undergo rigorous performance testing before leaving the factory. Among these tests, the balance performance test after tire assembly is a key step. This involves first assembling the wheel and tire together, then installing the assembled wheel and tire assembly onto the balance bar of a tire balancing machine. The machine is then used to test its balance and determine whether it meets the factory standards.

[0003] Because tires themselves have a certain weight, the assembled tire-wheel hub assembly is even more bulky. Currently, the installation of this assembly onto the balance bar of the balancing machine is mainly done manually. Manual handling and installation not only increase labor intensity but also pose risks of component damage or personnel injury due to improper operation. More importantly, manual operation is inefficient, directly reducing the overall testing efficiency of the wheel hub. Therefore, we propose a wheel hub unit bench testing device to solve these problems. Utility Model Content

There are four guide rods fixed between the mounting plate and the support plate, arranged in a rectangular pattern.

[0007] A slider is slidably fitted between two guide rods on the same side. A groove is constructed on the opposite side of the slider, and a support plate is slidably embedded inside the groove. The wheel hub to be tested is placed on top of the support plate.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] This application provides a wheel hub unit bench testing device, mainly to address the problems of increased labor intensity and the risk of component damage or personnel injury due to improper operation during manual handling and installation in existing technologies. More importantly, manual operation is inefficient, directly leading to a reduction in the overall testing efficiency of the wheel hub. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0023] A wheel hub unit bench testing device includes:

[0024] The balancing machine body 1 has a balance bar 101 on one side. A support plate 2 is connected to the bottom of the side of the balancing machine body 1 near the balance bar 101. An mounting plate 3 is fixed above the side of the balancing machine body 1 near the balance bar 101. A guide rod 4 is fixed between the mounting plate 3 and the support plate 2. There are four guide rods 4, which are arranged in a rectangular shape.

[0025] The slider 5 is slidably sleeved between the two guide rods 4 on the same side. The opposite side of the slider 5 is provided with a groove 501. A support plate 6 is slidably embedded in the groove 501. The wheel hub to be tested is placed on top of the support plate 6.

[0026] The lifting assembly 7 is disposed on both sides of the rectangular hole and is used to drive the slider 5 to rise or fall. The lifting assembly 7 includes a support frame 701 fixed on the top of the balancing machine body 1. A dual-axis motor 702 is installed in the middle of the support frame 701. The output shaft of the dual-axis motor 702 is connected to a winding reel 703. A traction rope 704 is wound inside the winding reel 703. The mounting plate 3 has strip holes 301 on both sides. The end of the traction rope 704 away from the winding reel 703 passes through the strip hole 301 and is connected to the slider 5.

[0027] It also includes limiting members 8, which are disposed on both sides of the rectangular channel 601. The limiting members 8 are used to limit the position of the wheel hub to be tested. The limiting members 8 include arc plates 801 fixed at the four corners of the rectangular channel 601, and connecting rods 802 are fixed between the middle parts of the arc plates 801 on the same side.

[0028] Workflow Description

[0029] The first step is to place and secure the tires.

[0030] The lifting assembly 7 controls the slider 5 to lower the pallet 6 to its lowest position. At this point, the height of the pallet 6 is convenient for the operator to place the tire hub assembly to be tested, reducing the difficulty of handling. The operator moves the wheel hub with the tire already installed to the pallet 6, aligns the wheel hub with the rectangular channel 601 in the middle of the pallet 6, and slowly places it into the rectangular channel 601. With the help of the arc-shaped plates 801 limiting parts 8 at the four corners of the rectangular channel 601, the wheel hub will automatically maintain a centered and stable state, avoiding subsequent installation deviations due to placement offset.

[0031] The second step is tire lifting and docking.

[0032] The dual-axis motor 702 of the lifting assembly 7 is started. The output shaft of the motor drives the winding reel 703 to rotate, winding the traction rope 704. Under the guidance of the guide wheel 705, the traction rope 704 pulls the slider 5 upward and rises vertically along the guide rod 4. The slider 5 simultaneously drives the support plate 6 and the wheel hub assembly to rise. The operator controls the dual-axis motor 702 to stop, so that the wheel hub assembly reaches the specified height level with the balance bar 101. Then, the operator pushes the support plate 6 to slide horizontally along the slide groove 501 on the slider 5 towards the balance bar 101, and continues to push until the balance bar 101 completely passes through the center hole of the wheel hub, ensuring that the wheel hub and the balance bar 101 are coaxially aligned.

[0033] Step 3: Locking in and Testing Preparation

[0034] Using the locking components (such as buckles, bolts, etc., not shown in the figure) pre-set at the end of the balance bar 101, the wheel hub is firmly fixed to the balance bar 101 to prevent the wheel hub from shaking or falling off during the test. The lifting assembly 7 is started again to control the dual-axis motor 702 to rotate in the opposite direction. The winding reel 703 releases the traction rope 704, and the slider 5 drives the support plate 6 to slowly descend to the initial low position along the guide rod 4 to avoid interference between the support plate 6 and the wheel hub assembly under test.

[0035] Step 4: Testing and Follow-up

[0036] Start-up test: After confirming that the pallet 6 is reset, start the balancing machine body 1. The equipment begins to perform a balance performance test on the tire hub assembly, collects and analyzes balance data in real time. After the test is completed, turn off the balancing machine, loosen the locking piece at the end of the balance bar 101, and raise the pallet 6 to the same height as the balance bar 101 again through the lifting component 7. Pull the lifting rod 602 to reset the pallet 6, remove the hub assembly that has been tested, and prepare for the next test cycle.

[0037] This device employs a vertical sliding combination of guide rod 4 and slider 5, and a horizontal sliding combination of slide groove 501 and support plate 6 to construct a two-dimensional adjustment system. In the vertical direction, precise height control is achieved through lifting component 7, and in the horizontal direction, smooth docking is achieved through slide groove 501. Limiting component 8 ensures tire stability. This solves the problem of difficulty in accurately aligning the balance bar 101 manually, significantly improving installation accuracy. At the same time, there is no need for manual lifting of the heavy tire and wheel hub assembly to the height of the balance bar 101; lifting and docking can be completed by the equipment, greatly reducing labor intensity.

[0038] like Figure 1 As shown, in some embodiments, a guide wheel 705 is provided on the top of the mounting plate 3 at the side of the strip hole 301. The traction rope 704 is slidably embedded in the groove of the guide wheel 705. More specifically, the traction rope 704 is slidably embedded in the groove of the guide wheel 705. The groove can limit the rope body and prevent it from deviating or leaving the preset path. At the same time, the rolling of the guide wheel 705 can convert the sliding friction of the traction rope 704 into rolling friction, which can greatly reduce the wear between the rope body and the mounting plate 3, extend the service life of the rope, and make the traction rope 704 pull more smoothly, ensuring the stability and efficiency of related transmission or adjustment actions.

[0039] like Figure 1 As shown, in some embodiments, the pallet 6 has a rectangular channel 601 in the middle. The outer diameter of the wheel hub to be tested is greater than the length of the rectangular channel 601. More specifically, because the outer diameter of the wheel hub is greater than the length of the rectangular channel 601, when the wheel hub is placed on the pallet 6, the edge of the wheel hub will overlap the plane of the pallet 6 on both sides of the channel, forming effective support. This design can directly restrict the position of the tire and prevent it from slipping out of the rectangular channel 601.

[0040] like Figure 2 As shown, in some embodiments, a lifting rod 602 is fixedly provided on the front of the pallet 6 at intervals, and the end of the lifting rod 602 is fitted with an anti-slip sleeve. More specifically, the lifting rod 602 is fixedly provided on the front of the pallet 6 at intervals, which can provide convenient gripping points, making it convenient for operators to move or adjust the position of the pallet 6, and solving the problem of inconvenient handling when there is no force point.
