[0002] Wheel dynamic balancing is an important part of automobile manufacturing and maintenance. It is mainly used to detect and correct vibration problems caused by uneven mass distribution when the wheel rotates at high speed.

[0003] A search of publication number CN221260216U reveals CN202322618876.X, which discloses an auxiliary device for a wheel dynamic balancing detection system, including a base, a wheel lifting adjustment component slidably connected to the top of the base, the wheel lifting adjustment component including a slide table, a limiting frame fixedly installed on the top of the slide table, a lifting table slidably connected to the inner wall of the limiting frame, a clamping component fixedly installed on the outer wall of the lifting table, the clamping component including a positioning plate, a stepper motor fixedly installed on the inner wall of the front end of the positioning plate, a pneumatic telescopic rod fixedly installed at the output end of the stepper motor, and an arc-shaped extrusion plate fixedly connected to the output end of the pneumatic telescopic rod. This device offers technical advantages such as "by using the wheel lifting adjustment component and the clamping component together, it is possible to automatically control the lifting and lowering of the wheel and adjust the rotation angle of the wheel when installing and removing it from the wheel dynamic balancing detection system, thereby improving work efficiency and saving manpower."

[0004] Existing wheel dynamic balancing testing devices suffer from insufficient adaptability when fixing wheels of different specifications. Traditional fixtures require frequent replacement of special adapters for wheel hubs with different bolt patterns, resulting in low testing efficiency and cumbersome operation. In particular, when encountering wheel hubs with non-standard bolt patterns or special specifications, it is often difficult to achieve fast and accurate positioning and fixing. This limitation seriously affects the continuity and efficiency of testing work, increases the workload of operators, and cannot meet the needs of modern repair shops for fast and universal testing equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a dynamic balancing testing device for wheels. By rotating a single knob seat, multiple circumferentially distributed bolt heads can be driven to move radially in a synchronized manner, achieving rapid and accurate wheel hub hole fitting and significantly improving clamping efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dynamic balancing testing device for wheels, comprising a base, with a first slide module and a second slide module respectively mounted on the rear and front ends of the top of the base. The second slide module is equipped with a testing mechanism for wheel dynamic balancing testing. The testing mechanism includes:

[0007] The positioning component includes a rotating shaft rotatably mounted on the slider of the second slide module. A rear cover seat is mounted on the front end of the rotating shaft. A front cover seat is fixed to the front end of the rear cover seat. Several circumferentially distributed sliding grooves are opened inside the front cover seat. A slide block is slidably mounted inside the sliding groove. A bolt head is fixed to the front end of the slide block. A knob seat is rotatably mounted between the rear cover seat and the front cover seat. Several circumferentially distributed connecting rods are pivotally connected to the front end of the knob seat, and the other end of the connecting rods is pivotally connected to the slide block.

[0008] A drive assembly, located at the front end of the base, is used to drive the wheels to rotate.

[0009] An execution component is set on the first slide module and used for wheel detection.

[0010] Preferably, the execution component includes a mounting plate fixed on the slider of the first slide module. Mounting brackets are fixed on both sides of the front end of the mounting plate. A dial indicator is mounted on the upper end of the mounting bracket. Two balance bars are slidably mounted through the lower end of the mounting bracket. A connecting plate is fixed between the upper ends of the two balance bars. A bearing is fixed between the lower ends of the two balance bars. A transmission roller is rotatably mounted on the lower end of the bearing.

[0011] Preferably, the actuating component further includes a spring sleeved and mounted on the outside of the balance bar, with the spring located between the mounting bracket and the bearing seat.

[0012] Preferably, the drive assembly includes a base fixed to the front end of the base, with an auxiliary wheel and a drive wheel rotatably mounted on the left and right sides of the upper end of the base, respectively, and a drive wheel mounted at the rear end of the motor for driving the drive wheel to rotate.

[0013] Preferably, the detection mechanism further includes a vibration sensor mounted on the slider of the second slide module for monitoring the rotating shaft.

[0014] Preferably, both the first slide module and the second slide module adopt a precision ball screw structure driven by a servo motor.

[0015] Beneficial effects

[0016] This invention provides a dynamic balancing detection device for wheels. Compared with the prior art, it has the following advantages:

[0017] 1. By rotating the knob seat and connecting rod, the slide block is driven to slide along the inside of the slide groove. The slide groove drives the bolt head to adjust the radial distance, so that the bolt head is accurately aligned with the wheel hub mounting hole. After the bolt head passes through the mounting hole on the wheel hub, the bolt is installed and tightened. By rotating a single knob seat, multiple circumferentially distributed bolt heads can be driven to move radially at the same time, so as to achieve fast and accurate wheel hub hole matching and greatly improve clamping efficiency.

[0018] 2. The first slide module precisely controls the overall downward movement of the actuator, establishing a stable contact relationship between the transmission roller and the rotating wheel surface. When the wheel has a dynamic balance deviation, its periodic vibration is effectively transmitted to the axle seat through the contact surface between the transmission roller and the wheel. The vibration energy is rigidly transmitted through the axle seat, driving two parallel balance bars to make precise synchronous vertical movements under the guidance of the mounting frame. The symmetrical double bars effectively avoid the off-center load error that may occur in single-point measurement. The connecting plate at the top of the balance bar directly couples the integrated vibration displacement to the dial indicator probe, converting the vibration displacement into a clear pointer reading.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a dynamic balancing detection device for wheels, including a base 1, with a first slide module 2 and a second slide module 3 respectively mounted on the rear end and front end of the top of the base 1. A detection mechanism 4 is provided on the second slide module 3 for wheel dynamic balancing detection. The detection mechanism 4 includes:

[0028] The positioning component 41 includes a rotating shaft 411 rotatably mounted on the slider of the second slide module 3. A rear cover seat 412 is mounted on the front end of the rotating shaft 411. A front cover seat 413 is fixed to the front end of the rear cover seat 412. A plurality of circumferentially distributed sliding grooves 414 are opened inside the front cover seat 413. A slide block 415 is slidably mounted inside the sliding grooves 414. A bolt head 416 is fixed to the front end of the slide block 415. A knob seat 417 is rotatably mounted between the rear cover seat 412 and the front cover seat 413. A plurality of circumferentially distributed connecting rods 418 are pivotally connected to the front end of the knob seat 417, and the other end of the connecting rods 418 is pivotally connected to the slide block 415.

[0029] Drive assembly 42 is disposed at the front end of base 1 and is used to drive the wheels to rotate;

[0030] Execution component 43 is set on the first slide module 2 and is used for wheel detection.

[0031] In this embodiment, rotating the knob seat 417 in conjunction with the connecting rod 418 drives the slide seat 415 to slide along the inside of the slide groove 414. The slide groove 414 drives the bolt head 416 to adjust the radial distance, so that the bolt head 416 is precisely aligned with the wheel hub mounting hole. After the bolt head 416 passes through the mounting hole on the wheel hub, the bolt is installed and tightened. By rotating a single knob seat 417, multiple circumferentially distributed bolt heads 416 can be driven to move radially in sync, achieving fast and accurate wheel hub hole adaptation and greatly improving clamping efficiency.

[0032] Specifically, the execution component 43 includes a mounting plate 431 fixed on the slider of the first slide module 2. Mounting brackets 432 are fixed on both sides of the front end of the mounting plate 431. A dial indicator 433 is mounted on the upper end of the mounting bracket 432. Two balance bars 434 are slidably mounted through the lower end of the mounting bracket 432. A connecting plate 435 is fixed between the upper ends of the two balance bars 434. A bearing seat 436 is fixed between the lower ends of the two balance bars 434. A transmission roller 437 is rotatably mounted on the lower end of the bearing seat 436.

[0033] In this embodiment, the first slide module 2 precisely controls the overall downward movement of the execution component 43, so that the transmission roller 437 establishes a stable contact relationship with the rotating wheel surface. When the wheel has a dynamic balance deviation, its periodic vibration is effectively transmitted to the axle seat 436 through the contact surface between the transmission roller 437 and the wheel. The vibration energy is rigidly transmitted through the axle seat 436, driving the two parallel balance bars 434 to make precise synchronous vertical movements under the guidance of the mounting bracket 432. The symmetrical double bars effectively avoid the off-center load error that may be caused by single-point measurement. The connecting plate 435 at the top of the balance bar 434 directly couples the integrated vibration displacement to the probe of the dial indicator 433, converting the vibration displacement into a clear pointer reading.

[0034] Specifically, the actuator 43 also includes a spring 438 sleeved and mounted on the outside of the balance bar 434, and the spring 438 is located between the mounting bracket 432 and the bearing seat 436.

[0035] In this embodiment, when the transmission roller 437 contacts the rotating wheel, the spring 438 can effectively absorb the vibration and impact force generated by the rotation of the wheel.

[0036] Specifically, the drive assembly 42 includes a base 421 fixed to the front end of the base 1. An auxiliary wheel 422 and a drive wheel 423 are rotatably mounted on the left and right sides of the upper end of the base 421, respectively. The drive wheel 423 is mounted on the rear end of the motor 424 and is used to drive the drive wheel 423 to rotate.

[0037] In this embodiment, the symmetrical layout of the drive system allows the wheel to be held and rotated stably by the auxiliary wheel 422 and the drive wheel 423 during the testing process, effectively avoiding the slippage that may occur with single-point drive and ensuring the uniformity and stability of the test speed.

[0038] Specifically, the detection mechanism 4 also includes a vibration sensor 44 installed on the slider of the second slide module 3 for monitoring the rotating shaft 411.

[0039] In this embodiment, through the coordinated operation of the vibration sensor 44 and the positioning component 41, the vibration signal caused by uneven mass distribution can be accurately captured during the rotation of the wheel, thereby more comprehensively evaluating the dynamic balance state.

[0040] Specifically, both the first slide module 2 and the second slide module 3 adopt a precision ball screw structure driven by a servo motor.

[0041] The working principle and usage process of this utility model are as follows: First, by rotating the knob seat 417 in conjunction with the connecting rod 418, the slide 415 is driven to slide along the inside of the slide groove 414. The slide groove 414 drives the bolt head 416 to adjust the radial distance, so that the bolt head 416 is precisely aligned with the wheel hub mounting hole. After the bolt head 416 passes through the mounting hole on the wheel hub, the bolt is installed and tightened. Then, the second slide module 3 controls the wheel fixed on the positioning component 41 to contact the auxiliary wheel 422 and the drive wheel 423.

[0042] Then, the symmetrical layout of the drive system allows the wheel to be held and rotated stably by the auxiliary wheel 422 and the drive wheel 423 during the testing process, effectively avoiding the slippage that may occur with single-point drive and ensuring the uniformity and stability of the test speed.

[0043] Finally, the first slide module 2 precisely controls the overall downward movement of the execution component 43, so that the transmission roller 437 establishes a stable contact relationship with the rotating wheel surface. When the wheel has a dynamic balance deviation, its periodic vibration is effectively transmitted to the axle seat 436 through the contact surface between the transmission roller 437 and the wheel. The vibration energy is rigidly transmitted through the axle seat 436, driving the two parallel balance bars 434 to make precise synchronous vertical movements under the guidance of the mounting bracket 432. The symmetrical double bars effectively avoid the off-center load error that may be caused by single-point measurement. The connecting plate 435 at the top of the balance bar 434 directly couples the integrated vibration displacement to the probe of the dial indicator 433, converting the vibration displacement into a clear pointer reading.
