Description

Technical Field

[0001] This invention belongs to the field of dynamic balancing machine technology, specifically referring to an integrated wheel dynamic balancing correction machine. Background Technology

[0002] Wheel dynamic balancing is a critical process in vehicle maintenance, affecting ride comfort, safety, and component lifespan. Traditional wheel dynamic balancing correction processes typically rely on manual operation and the collaboration of multiple distributed devices, resulting in low efficiency, high labor intensity for personnel, and precision dependence on human experience.

[0003] The traditional procedure involves operators moving the tire assembly to the balancing machine for dynamic balancing measurements.

The tire is then removed from the balancing machine, and counterweights are attached according to the marks. This process often requires removing and reinstalling dirty tires and multiple verifications to achieve the required tire balance. Human intervention is significant in this process, making it prone to inaccurate corrections due to human judgment or operational errors. Summary of the Invention

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 11 : like Figure 2 As shown, a wheel dynamic balancing correction integrated machine includes a vertical dynamic balancing machine 1. A frame 2 is provided on one side of the dynamic balancing machine 1. A wheel turning device 3 and a lifting and positioning device 4 are slidably connected from top to bottom on the frame 2 via longitudinal slide rails 20. A clamping and centering rotating device 5 is fixed at the bottom of the wheel turning device 3. The clamping and centering rotating device 5 and the lifting and positioning device 4 are located below the dynamic balancing machine 1. A conveying device 6 is provided on one side of the lifting and positioning device 4. A balancing block application platform 7 is provided on one side of the dynamic balancing machine 1.

[0025] During implementation, the tire assembly is fed into the conveying device 6 by AGV or manual loading. The conveying device 6 moves the tire assembly to the lifting and positioning device 4, where it is centered and clamped by the clamping and centering rotating device 5. The lifting and positioning device 4 lowers to allow the dynamic balancing machine 1 to assemble with the tire assembly. After reading the tire's dynamic balance data, the centering and rotating device 5 clamps the tire assembly, and the wheel flipping device 3 flips the tire. The operator at the balancing block application platform 7 applies the balancing blocks, thus achieving balancing. For balancing at multiple points, the centering and rotating device 5 rotates the tire to reach the designated application position. After application, the wheel flipping device 3 places the tire back onto the dynamic balancing machine 1 for retesting and dynamic balance calibration. After calibration, the tire is unloaded.

[0026] like Figure 5 and Figure 6 As shown, the wheel tilting device 3 includes a lifting seat plate 30 that slides on the longitudinal slide rail 20. The front end of the lifting seat plate 30 is provided with two sets of left-right symmetrical tilting drive mechanisms 31. Each of the two tilting drive mechanisms 31 includes a tilting cylinder 310. The piston output end of the tilting cylinder 310 is driven by a tilting output shaft 311 through a connecting rod. A tilting output shaft seat 32 is coaxially fixed between the two tilting output shafts 311.

[0027] During the implementation of the wheel tilting device 3, the lifting seat 30 is used for the overall raising and lowering, enabling the tire assembly to cooperate with the dynamic balancing machine 1 during the unloading process. The lifting seat is T-shaped, and the tilting drive mechanism 31 is located on both sides of the lifting seat 30. The tilting cylinder 310 is rotatably connected to the lifting seat 30 near the piston end. Its piston end controls the rotation of the tilting output shaft 311 through a straight connecting plate. During the alternating piston movement of the tilting cylinder 310, it drives the tilting output shaft 311 to rotate at a certain angle and perform reciprocating motion. This facilitates switching between the two working states of the bottom clamping centering rotation device 5: the horizontal state for dynamic balancing and the vertical state for attaching balance blocks.

[0028] like Figure 7 and Figure 8 As shown, the clamping centering rotation device 5 includes a rotary servo motor 50 fixed on the flip output shaft seat 32. A clamping frame 51 is fixed on the output shaft of the rotary servo motor 50. Two clamping sliders 52 are provided at the bottom of the clamping frame 51 and slide along two sets of parallel slide rails 510. Several clamping clamping rods 53 are fixed at the bottom of each clamping slider 52. Clamping drive cylinders 54 are fixed on the two side walls of the clamping frame 51 to drive the two clamping sliders 52 to slide along the parallel slide rails 510. Racks 55 with facing tooth surfaces are fixed on the two clamping sliders 52. A synchronous gear 56 that meshes with the two racks 55 is rotatably connected to the middle of the bottom of the clamping frame 51. When the clamping drive cylinders 54 drive the clamping sliders 52 to move along the parallel slide rails 510, the two clamping sliders 52 move synchronously towards or away from each other.

[0029] In the above structure, the clamping and centering rotation device 5 is controlled by a rotary servo motor 50 to rotate the whole. The purpose of rotation is to indicate the balance position of the balance block when different need to be applied, so that the user can apply the patch. Furthermore, the two sets of clamping sliders 52 that can slide synchronously along the parallel slide rail 510 realize the synchronous clamping of the tire assembly, and keep the tire assembly in the center position during rotation. When switching the point of applying the balance block, the accuracy is effectively maintained and the retest rate is reduced.

[0030] like Figure 9 and Figure 10 As shown, the lifting and positioning device 4 includes a lifting frame 40 along a longitudinal slide rail 20 and driven by a cylinder. The top of the lifting frame 40 is provided with two sets of conveyor belts 41 driven synchronously by a motor. A lifting connecting plate 42 fixed to the top of the lifting frame 40 is provided between the two conveyor belts 41. Several longitudinally arranged lifting cylinders 43 are fixed on the lifting connecting plate 42. A platform middle plate 44 is fixed to the top of the piston end of the several lifting cylinders 43. An opening 440 for the top of the dynamic balancing machine 1 to pass through is opened in the middle of the platform middle plate 44.

[0031] In the above structure, the lifting and positioning device 4 is driven by two sets of conveyor belts 41 that operate simultaneously, moving the tire assembly transported by the conveyor to the top of the platform center plate 44, facilitating the subsequent gripping of the centering and rotating device 5. The other two sets of conveyor belts 41 are driven by chains and sprockets, with the two sprockets being driven synchronously by the motor through a shaft.

[0032] Furthermore, during use, when the lifting cylinder 43 is conveyed to the platform's middle plate 44 by the conveying device, the piston rod of the lifting cylinder 43 moves upward, lifting the tire assembly to prevent it from being further moved to one side by the conveyor belts 41 on both sides, thus facilitating subsequent clamping. Preferably, the top of the platform middle plate 44 is provided with several load-bearing universal balls 45, and several sensors 46 for detecting the height of the platform middle plate 44 are fixed on the lifting frame 40. During the process of the platform middle plate 44 supporting the tire assembly, the sensors 46 effectively limit the movement range of the lifting cylinder, allowing the clamping and centering rotation device to accurately grasp the tires.

[0033] like Figure 3 and Figure 4 As shown, the conveying device 6 includes a conveying support frame 60, on which a tilting frame 61 driven by a motor is hinged. Two sets of parallel conveying frames 62 are fixed on the tilting frame 61, and several parallel rollers 620 are rotatably connected between the two conveying frames 62. A roller baffle plate 63 is fixed at the end of the two conveying frames 62, and several roller baffle rods 64 are fixed on the roller baffle plate 63. Tire loading and unloading baffles 65 are fixed on the roller baffle rods 64.

[0034] In the above structure, an inclined platform is provided on the front side of the conveying device 6 to facilitate the tire rolling onto the conveying device 6. The tilting frame 61 lifts the tire assembly so that it can move to the height required by the dynamic balancing machine. Several guide rollers 64 and loading / unloading baffles 65 can prevent the tire assembly from falling off during the tilting process.

[0035] Preferably, the conveying support frame 60 is provided with a support cylinder 66, the cylinder body of the support cylinder 66 is inclined, the piston end of the support cylinder 66 is movably connected to the bottom of the tilting frame 61 by a hinge, and the number of support cylinders 66 is two or more.

[0036] Furthermore, the end of the supporting cylinder 66 is hinged, and when it rotates with the tilting frame 61, the end rotates to a certain extent to ensure the supporting effect. At the same time, two or more supporting cylinders 66 can enhance stability.

[0037] Preferably, the roller mounting plate 63 has a plurality of roller holes 630, and a plurality of roller rods 64 are inserted into the roller holes 630 to form a C-shaped tire abutment groove. This facilitates the tire assembly to be embedded in the tire abutment groove, improving stability during tilting and lifting.

[0038] like Figure 11 As shown, the balancing block platform 7 includes a platform support 70 located in front of the dynamic balancing machine 1, a step pedal 71 is provided on the platform support 70, and an infrared indicator light 72 is provided on the top of the platform support 70 to illuminate one side of the dynamic balancing machine 1.

[0039] During implementation, the infrared indicator light 72 typically uses a ray to illuminate the vertically positioned tire assembly, facilitating operator confirmation of the balance weight placement points. The balance weight placement platform 7 provides operators with designated operating areas, effectively simplifying the overall operation, increasing the speed and success rate of weight placement, and reducing physical exertion.

[0040] Preferably, the platform support 70 is equipped with a control box 73 and several lighting components 74. This optimizes the operating environment and improves operational accuracy.

[0041] At the same time, such as Figure 1 As shown, several safety nets are set up around the entire wheel dynamic balancing and correction integrated machine to provide protection.

[0042] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
