Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of wheel inspection equipment, specifically relating to a fully automatic wheel dynamic balancing inspection machine. Background Technology
[0002] In modern transportation systems, automobiles have become the primary means of travel and freight transport. The stability and safety of vehicle operation are directly related to the lives and property of road users. As a key component that directly contacts the road surface, the dynamic balance of the wheels plays a decisive role in vehicle performance. If the wheels are dynamically unbalanced, centrifugal force will be generated during high-speed rotation, leading to problems such as steering wheel vibration, abnormal tire wear, and vehicle drift. This not only reduces driving comfort but also accelerates the wear and tear of vehicle parts and can even cause serious traffic accidents.
[0003] Traditional wheel balancing methods typically rely on specialized balancing machines. Operators must first remove the wheels from the vehicle, manually install them onto the machine, and then use the machine's rotation to detect the location and weight difference of any imbalance. Adjustments are then made by adding balance weights. This method has several limitations: First, the process is cumbersome, taking a considerable amount of time from wheel removal to calibration, significantly impacting vehicle maintenance efficiency, especially in today's society with its large vehicle fleet, making it difficult to meet the market's demand for fast service. Second, it is highly dependent on specialized equipment and operators; professional balancing machines are expensive and require specially trained technicians, increasing operating costs for auto repair shops and limiting the application of wheel balancing services in a wider range of scenarios. Utility Model Content
[0004] The purpose of this invention is to provide a fully automatic wheel dynamic balancing testing machine that overcomes the shortcomings of the prior art. Through the cooperation of the first synchronous transmission component and the second synchronous transmission component, the tire is centered and then transmitted to the dynamic balancing spindle for testing. No manual installation is required, which improves the efficiency of tire dynamic balancing testing.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0006] A fully automatic wheel dynamic balancing testing machine includes a first synchronous transmission component, a dynamic balancing testing spindle, a positioning component, a second synchronous transmission component, and a correction mechanism.
[0007] The second synchronous transmission component is mounted on the frame and located on one side of the first synchronous transmission component. The first synchronous transmission component and the second synchronous transmission component are arranged in parallel. The alignment mechanism is installed directly above the second synchronous transmission component and is used to adjust the position of the tire conveyed at the previous station.
[0008] The dynamic balancing detection spindle is installed inside the first synchronous transmission component, and the positioning component is installed outside the first synchronous transmission component. The end of the first synchronous transmission component near the second synchronous transmission component is provided with a lifting component that drives the first synchronous transmission component to move vertically up and down.
[0009] Furthermore, the first synchronous transmission component includes a base plate and two synchronously driven first transmission belts mounted on the base plate, and the dynamic balance detection main shaft is located between the two first transmission belts. The positioning component includes two projectors and two receivers, and the two projectors and two receivers are respectively located on both sides of the dynamic balance detection main shaft for detecting the position of the tire.
[0010] Furthermore, the lifting assembly includes a lifting motor mounted on the base plate, a vertically arranged ball screw, lifting slide rails located on both sides of the ball screw, a movable block threaded to the outside of the ball screw, and a movable bracket fixedly connected to the movable block.

[0011] To improve the stability of the lifting and lowering of the first synchronous transmission component 1, a balance cylinder is installed on one side of the lifting component 3, and the top of the balance cylinder is fixedly connected to the movable bracket 34. During the process of the lifting component 3 driving the first synchronous transmission component 1 to lift and lower, the air circuit control of the balance cylinder is used to coordinate the lifting and lowering of the first synchronous transmission component 1, which plays a role in safety protection and preventing falls.
[0012] Furthermore, the second synchronous transmission component includes two synchronously driven second conveyor belts, and a number of matrix-distributed omnidirectional ball bearings are arranged between and on both sides of the two second conveyor belts. A lifting cylinder is arranged between the frame and the second synchronous transmission component to drive the two second conveyor belts to rise and fall.
[0013] Furthermore, the correction mechanism includes a synchronous drive component and four sets of synchronous drive adjustment components, wherein the synchronous drive component is connected to the four sets of adjustment components in a transmission manner.
[0014] Furthermore, the synchronous drive assembly includes a mounting plate, a fixed beam fixed directly above the mounting plate, at least one drive motor mounted on the fixed beam, four drive wheels corresponding to the adjustment assembly, and at least two guide wheels.

[0016] Compared with the prior art, this utility model has the following advantages:
[0017] 1. This utility model uses a second synchronous transmission component to transmit the tire to the area below the alignment mechanism. After the alignment mechanism adjusts the tire's position, the tire is then transmitted to the first synchronous transmission component. The first synchronous transmission component lowers the tire via a lifting component to mount it onto the dynamic balance testing spindle for testing. After testing, the tire is transported away via the first synchronous transmission component. The entire process is automated, eliminating the need for manual handling and installation, thus improving the efficiency of tire dynamic balance testing.
[0018] 2. In this utility model, the tire centering and alignment station and the dynamic balancing test station are separated, and automatic transmission is carried out through the second synchronous transmission component and the first synchronous transmission component, which effectively improves work efficiency.
[0019] 3. This utility model uses a synchronous drive assembly to synchronously drive four sets of clamping rods to move synchronously, thereby correcting and centering the tire and improving the centering accuracy. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] like Figures 1-5 As shown, the fully automatic wheel dynamic balancing testing machine of this utility model includes a first synchronous transmission component 1, a dynamic balancing testing spindle 2, a positioning component 13, a second synchronous transmission component 5, and a correction mechanism 6.
[0028] The second synchronous transmission component 5 is mounted on the frame 4 and is located on one side of the first synchronous transmission component 1. The first synchronous transmission component 1 and the second synchronous transmission component 5 are arranged in parallel. The alignment mechanism 6 is mounted directly above the second synchronous transmission component 5 and is used to position the tires conveyed at the previous station.
[0029] The dynamic balancing detection spindle 2 is installed inside the first synchronous transmission component 1, and the positioning component 13 is installed on the outside of the first synchronous transmission component 1. The first synchronous transmission component 1 is provided with a lifting component 3 that drives the first synchronous transmission component 1 to move vertically up and down at one end near the second synchronous transmission component 5.
[0030] In use, the second synchronous transmission component 5 transmits the tire from the front-end process to directly below the alignment mechanism 6. After the position is determined by the positioning sensor, the alignment mechanism 6 is activated to adjust the tire's position on the second synchronous transmission component 5. After adjustment, the tire is then transmitted from the second synchronous transmission component 5 to the first synchronous transmission component 1. After the positioning component 13 detects that the tire has reached the detection position, the first synchronous transmission component 1 is closed, and the lifting component 3 is activated to move the tire downwards and install it onto the dynamic balancing detection spindle 2. At this time, the drive mechanism of the dynamic balancing detection spindle 2 detects and acquires the dynamic balance data of the tire through the pressure sensor inside the dynamic balancing detection spindle 2. The dynamic balance data is transmitted to the next station to complete the dynamic balance detection of the tire. Then, the lifting component 3 is activated again to remove the tire from the dynamic balancing detection spindle 2 and transmit it to the next process.
[0031] To facilitate testing, the first synchronous transmission component 1 includes a base plate 11 and two synchronously driven first transmission belts 12 mounted on the base plate 11. The dynamic balancing detection main shaft 2 is located between the two first transmission belts 12. The positioning component 13 includes two projectors and two receivers, which are located on both sides of the dynamic balancing detection main shaft 2 to detect the tire position. The positioning component 13 determines the tire position through the cooperation of the projectors and receivers, which facilitates subsequent dynamic balancing testing.
[0032] To drive the first synchronous transmission component 1 to rise and fall, the lifting component 3 includes a lifting motor 31 mounted on the base plate 11, a vertically arranged ball screw 33, lifting slide rails 32 located on both sides of the ball screw 33, a movable block threadedly connected to the outside of the ball screw 33, and a movable bracket 34 fixedly connected to the movable block. The lifting motor 31 is used to drive the ball screw 33 to rotate. The movable bracket 34 is slidably connected to the lifting slide rails 32, and the top of the movable bracket 34 is fixedly connected to the fixed beams in the two first transmission belts 12 respectively. After the lifting motor 31 starts, it drives the ball screw 33 to rotate, thereby driving the movable block to move along the ball screw 33, and then driving the movable bracket 34 and the first synchronous transmission component 1 to complete the lifting and falling.
[0033] To improve the stability of the lifting and lowering of the first synchronous transmission component 1, a balance cylinder is installed on one side of the lifting component 3, and the top of the balance cylinder is fixedly connected to the movable bracket 34. During the process of the lifting component 3 driving the first synchronous transmission component 1 to lift and lower, the air circuit control of the balance cylinder is used to coordinate the lifting and lowering of the first synchronous transmission component 1, which plays a role in safety protection and preventing falls.
[0034] To facilitate alignment, the second synchronous transmission component 5 includes two synchronously driven second transmission belts 51, and several matrix-distributed universal balls 52 are arranged between and on both sides of the two second transmission belts 51. A lifting cylinder is arranged between the frame 4 and the second synchronous transmission component 5 to drive the two second transmission belts 51 to rise and fall. When the tire moves on the second synchronous transmission component 5 to directly below the alignment mechanism 6, the lifting cylinder is activated to lower the second transmission belts 51 so that the tire falls onto the universal balls. Then, the alignment mechanism 6 is used to align and center the tire. Then, the lifting cylinder is activated again to raise the second transmission belts 51 and transfer the tire to the first transmission belt 12.
[0035] The correction mechanism 6 includes a synchronous drive component and four sets of synchronous drive adjustment components, which are connected in transmission to the four sets of adjustment components.
[0036] The synchronous drive assembly includes a mounting plate 61, a fixed beam 62 fixed directly above the mounting plate 61, at least one drive motor 63 mounted on the fixed beam 62, four drive wheels 64 corresponding to the adjustment assembly, and at least two guide wheels 65. A transmission belt 66 is provided between the four drive wheels 64, and the guide wheels 65 are in contact with the outer side of the transmission belt 66. The synchronous drive assembly relies on one or two drive motors 63 to drive the four drive wheels 64 to rotate synchronously, thereby controlling the synchronous movement of the adjustment assembly.
[0037] The adjustment assembly includes a slider 68, a clamping rod 67 fixed to the bottom of the slider 68, and a rack 610 fixed to one side of the slider 68. A drive gear 69 is meshed on one side of the rack 610, and the top of the drive gear 69 is connected to the drive wheel 64. A cross-shaped guide bar 611 is fixed on the lower end face of the mounting plate 61, and the slider 68 is slidably connected to the guide bar 611. The drive wheel 64 drives the drive gear 69 by rotating, and the meshing of the drive gear 69 and the rack 610 drives the slider 68 to slide on the guide bar 611, thereby driving the clamping rod 67 to move. The four clamping rods 67 retract inward along the guide bar 611 at the same time to adjust the position of the tire.
[0038] In summary, the fully automatic wheel dynamic balancing testing machine described in this utility model adopts a vertical structure, which reduces the overall height of the equipment and reduces energy consumption; the open design facilitates later maintenance; the equipment operates fully automatically, eliminating the need for manual handling and installation, thus improving the efficiency and accuracy of wheel dynamic balancing testing.
