Description

Technical Field

[0001] This invention relates to the field of automotive application equipment, and specifically to a wheel hub positioning device for automotive inspection. Background Technology

[0002] Four-wheel alignment is an essential step in automotive maintenance and repair. The accuracy of four-wheel alignment directly impacts driving safety. Wheel alignment equipment is primarily used to detect the relative positions and alignment angles between the wheels of a vehicle to determine wheel alignment parameters. This ensures smooth and safe driving, reduces fuel consumption and tire wear. Areas for improvement in wheel alignment include:

[0003] In existing positioning equipment, when positioning wheel hubs, the wheel is placed on a swivel plate. The operator uses the swivel plate to adjust the four wheels of the car to a parallel state. Therefore, as the swivel plate rotates, it will drive the wheels to rotate and adjust. Since the swivel plate only has a few anti-slip protrusions, its contact surface with the wheel is relatively smooth, and the contact friction between the two is small. Because the swivel plate and the wheel cannot fit perfectly, the wheel has a relative space to move on the swivel plate. As a result, when the swivel plate rotates, it cannot drive the wheel to rotate at the same amplitude. Therefore, the equipment cannot achieve the desired positioning effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution: a wheel hub positioning device for automobile inspection, comprising a first fixed base, an adjusting component, a blocking block, a platform, a limiting device, a lifting frame, and a hydraulic rod.

[0013] The present invention provides a wheel hub positioning device for automobile inspection, which has the following beneficial effects:

[0014] This invention combines a mounting base, a debugging base, a corner plate, a first connecting plate, a docking limiter, and extension clips. When an operator moves a car onto the platform, the front and rear wheels of the car are placed on the corner plate and the rear wheel tray, respectively. Two extension clips are used to hold the wheels in place on both sides. The docking limiter extends into the wheel and assists the extension clips in limiting the wheels, allowing the wheels to rotate with the corner plate at the same amplitude under the action of the extension clips. The corner plate is used to position and adjust the wheels.

[0015] This invention combines a cavity, telescopic stops, locking blocks, extension strips, and auxiliary components. When the wheel is positioned between two telescopic stops, the operator pulls the telescopic stops upwards. The locking blocks inside the telescopic stops extend upwards under the pulling force, and the extension strips and auxiliary components also extend upwards under the pulling force of the locking blocks, effectively extending the telescopic stops so that they can stably rest against both sides of the wheel, effectively restricting the wheel's movement.

[0016] This invention utilizes a combination of a connector, stacked tubes, a restraining belt, a winding component, a mounting bracket, a top protrusion, a sliding groove, a U-shaped clamp, and a socket. When the wheel enters the turntable, the operator pulls the two mounting brackets outwards, causing the top protrusion and U-shaped clamp on the brackets to separate. The stacked tubes on the sides of the two mounting brackets retract under the action of the winding component. When the wheel enters the turntable and rests between the two telescopic stops, the top protrusion and U-shaped clamp on the two mounting brackets are pulled inwards, causing the stacked tubes to extend outwards. The winding component rotates with the movement of the stacked tubes. After the top protrusion and U-shaped clamp are fastened together, the winding component, when no longer under tension, pulls the restraining belt back, allowing the two stacked tubes to connect to the wheel hub, effectively assisting the telescopic stops in limiting the overall wheel position.

One end of the three shock-absorbing components 52 away from the mounting base 51 is fixedly connected to the first connecting plate 55. The other end of the first connecting plate 55 is fitted to the bottom of the adjustment base 53. A corner plate 54 is installed on the top of the adjustment base 53 and the two are movably connected. Two parallel extension clips 57 are inserted into the top of the corner plate 54. The ends of the two extension clips 57 away from the corner plate 54 are both inserted into the docking limiter 56. The mounting base 51 is fixed on the platform 4. Both ends of the corner plate 54 are provided with blocking blocks 3.

[0027] Please see Figure 2 The corner disc 54 includes an anti-slip coating 541, a disc body 542, anti-slip protrusions 543, and a top surface 544. The anti-slip coating 541 is applied to the top surface 544. The top surface 544 facing the anti-slip coating 541 has a plurality of anti-slip protrusions 543 connected thereto.

Slide rails 528 are provided on both sides of the grooves of the second fixed seats 525, and the slide rails 528 are slidably connected to the slider 524. The other end of the slider 524 is embedded in the spring-loaded top element 527. An airbag 526 is provided inside the spring-loaded top element 527. Two spring-loaded top elements 527 are provided, each on one of the two second fixed seats 525. A pushing element 523 connects the two spring-loaded top elements 527. Both ends of the two second fixed seats 525 are connected to the mounting base 51 and the first connecting plate 55.

[0030] The airbag 526 mentioned above is used in conjunction with the spring-loaded top component 527. The airbag 526 is installed inside the spring-loaded top component 527. When the car moves onto the turntable 54, the turntable 54 will transmit the heavy pressure of the car to the first connecting plate 55 through the adjustment seat 53. The first connecting plate 55 will distribute the pressure to the three second fixed seats 525. The second fixed seats 525 will move downward under pressure, and the spring-loaded top component 527 will move downward accordingly to squeeze the pushing member 523. The pushing member 523 will transmit the pressure to the lower spring-loaded top component 527. The airbag inside the spring-loaded top component 527 will buffer and absorb the heavy pressure of the car.

[0031] Please see Figure 3 The pushing component 523 includes a movable cavity E1, an elastic steel plate E2, a tensioning fork E3, a connecting pull bar E4, and a connecting arc piece E5.

The two ends of the two connecting arc pieces E5 are connected to the top of two elastic arc top pieces 527. The movable cavity E1 is located between the connecting arc pieces E5 and the elastic arc top pieces 527.

[0032] The aforementioned elastic steel plate E2 is used to cooperate with the connecting arc plate E5. The elastic steel plate E2 extends through the connecting arc plate E5 and is made of elastic steel, which has good elastic support force and can effectively support the connecting arc plate E5, so that the connecting arc plate E5 will deform and bend after being compressed.

[0041] Please see Figure 5 The docking limiting component 56 includes a connector 561, a stacked tube 562, a restraining strap 563, a winding component 564, a retainer 565, a top protrusion 566, a slide groove 567, a U-shaped retainer 568, and a socket 569. The connector 561 is inserted into the end of the stacked tube 562, and the other end of the stacked tube 562 is fixedly connected to the retainer 565. A winding component 564 is provided in the middle of the stacked tube 562, and restraining straps 563 are connected to both ends of the winding component 564.

[0043] Please see Figure 5 The winding component 564 includes a chuck G1, a rotating head G2, a guide plate G3, a rotating rod G4, a clamping head G5, a compression spring G6, and a blocking plate G7. The guide plate G3 is located inside the chuck G1. Two blocking plates G7 are inserted between the guide plate G3 and the chuck G1. One side of the two blocking plates G7 is fastened to one end of the compression spring G6. The other end of the compression spring G6 is fastened to the rotating rod G4. There are two rotating rods G4, which are embedded on both sides of the rotating head G2. The middle position of the rotating rod G4 is connected to the guide plate G3 and the two are movably connected. The end of the rotating rod G4 away from the rotating head G2 is inserted with a clamping head G5. The clamping head G5 is connected to the restraining belt 563. The chuck G1 is located in the middle position of the stacked tube 562.

[0044] The aforementioned blocking plate G7 is used to cooperate with the rotating rod G4. A compression spring G6 is connected between the blocking plate G7 and the rotating rod G4. The clamp G5 is connected to the restraining band 563. When the stacked tube 562 extends outward, the restraining band 563 will extend outward along with the stacked tube 562. The rotating rod G4, restrained by the clamp G5, will rotate on the guide plate G3 through the rotating head G2. During the rotation, the rotating rod G4 will squeeze the compression spring G6 upward, and the compression spring G6 will contract accordingly. The blocking plate G7 limits the position of the compression spring G6, thus restricting the rotation position of the rotating rod G4.

[0045] The working principle of the above technical solution is explained below:

[0046] In use, the operator adjusts the lifting frame 6 and hydraulic rod 7 to move the platform 4 downwards, then steadily moves the car onto the two platforms 4, placing the car's four wheels on the top surface 544 of the platform 4. The top surface 544 is provided with an anti-slip coating 541 and multiple anti-slip protrusions 543. The anti-slip coating 541 is made of epoxy floor coating, which, together with the anti-slip protrusions 543, increases the anti-slip effect of the top surface 544. After the wheels are placed on the disc body 542, the disc body 542 will be subjected to the weight pressure of the wheels, which is transmitted to the first contact via the adjustment seat 53. On plate 55, the first connecting plate 55 is fixed together with the second fixed seat 525. The first connecting plate 55 will evenly distribute the pressure on the three second fixed seats 525. The second fixed seats 525 will move downward under the action of the compression spring rod 522 when under pressure. The compression spring rod 522 will transmit the heavy pressure to the bottom second fixed seat 525. During the downward movement of the second fixed seat 525, the slide rail 528 will slide downward with the sliders 524 on both sides of the spring arc top member 527 under the action of the second fixed seat 525. The space between the spring arc top member 527 and the second fixed seat 525 The elastic element 521 will be compressed under force, absorbing part of the heavy pressure on the second fixed seat 525, and then transmitting the remaining pressure to the spring arc top element 527. After being stressed, the spring arc top element 527 will transmit the pressure to the lower spring arc top element 527 through the connecting arc plate E5. The connecting arc plate E5 will bend downward after being stressed. It has an elastic steel plate E2 inside, which can help support the connecting arc plate E5. During the bending of the connecting arc plate E5, the opening and closing fork E3 will open outward with the movement of the connecting arc plate E5. Two connecting strips E4 restrain the opening and closing fork E3, allowing the opening and closing fork E3 to restrain the connecting arc plate E5 under the action of the connecting strips E4. The heavy pressure is transmitted to the lower spring arc top piece 527 through the connecting arc plate E5, so that the two spring arc top pieces 527 can be evenly stressed. After the spring arc top piece 527 is stressed, it will indent inward and transmit the pressure to the airbag 526. The airbag 526 has a buffering function and can absorb and buffer the heavy pressure on the spring arc top piece 527, so that the car wheel can be stably placed on the turning plate 54.

[0047] After the car is moved into the disc 542, the operator pulls the telescopic stop 572 upwards. The locking blocks 573 inside the telescopic stop 572 extend upwards under its influence. The locking blocks 573 at both ends of the telescopic stop 572 are fixedly connected to the top and bottom of the telescopic stop 572. During movement, the locking blocks 573 have inserts 576 on both sides, with both ends of the inserts 576 connected to the extension strips 575. As the locking blocks 573 move upwards, the extension strips 575 extend and open under the influence of the inserts 576, thus restraining the locking blocks 573. As the locking blocks 573 extend with the telescopic stop 572, the positioning plate F1 connected between the two locking blocks 573 is subjected to… As the traction force adjusts with the movement of the locking block 573, the positioning plate F1 is pulled, and the sleeve F4 connected to its lower end opens outward with the positioning plate F1. The retaining slide F2 on the inner wall of the upper sleeve F4 engages with the slide head F5 on the outer wall of the lower sleeve F4 for sliding adjustment. After the upper and lower sleeves F4 extend to a certain position, the slide head F5 on their outer walls will lock into the lower recess of the retaining slide F2. The support plate F3 pulls and limits the two sleeves F4, allowing the locking block 573 to extend and adjust stably inside the cavity 571 as the telescopic stop 572 extends. After the telescopic stop 572 extends upward to a certain limit, it can block the sides of the car, restricting the movement space of the wheels and confining the movement space of the wheels to the stacked tube between the two telescopic stop 572 pieces. One end of 562 is inserted into the top of the second connecting plate 574. When the wheel is placed between the two telescopic stops 572, the operator pulls the two card seats 565, and the stacked tube 562 on the card seats 565 will extend and open accordingly. A restraining strap 563 is connected through the stacked tube 562. The other end of the restraining strap 563 is connected to the clamp head G5, so that during the extension of the stacked tube 562, the restraining strap 563 is driven by the pulling force of the stacked tube 562 to move the clamp head G5. The clamp head G5 is fixedly connected to the sleeve F4. The pulling force of the clamp head G5 on the rotating rod G4 can serve as the power for the rotation of the rotating head G2, so that the rotating rod G4 can rotate on the guide plate G3. During the rotation, the rotating rod G4 will squeeze the compression spring G6 upward, and the compression spring G6 will contract accordingly, through the resistance The baffle G7 limits the position of the compression spring G6 and restricts the rotation position of the rotating rod G4. After the stacked tubes 562 extend outward to a certain limit, the U-shaped clips 568 and the top protrusions 566 on the two clips 565 mate. The U-shaped clips 568 have grooves 567 on both sides. The two sides of the top protrusions 566 slide into the grooves 567 and lock together with the U-shaped clips 568. The two ends of the U-shaped clips 568 fit into the sockets 569, allowing the two stacked tubes 562 to be joined together. After the two stacked tubes 562 are joined, the compression spring G6 will generate a rebound force under no pressure, pushing the rotating rod G4 outward. The rotating rod G4 can pull the restraining band 563 inward and rewind it through the clamp G5, and the stacked tubes 562 will also retract accordingly.The two stacked tubes 562 can secure the wheel to the two telescopic stops 572. The telescopic stops 572 limit the wheel's movement, allowing the wheel to rotate and be positioned and adjusted in the same manner as the wheel under the action of the telescopic stops 572 when the angle plate 54 rotates on the adjustment seat 53 to adjust the wheel. This ensures the wheel hub can be adjusted to a four-wheel parallel positioning state.

[0048] In summary, this invention employs a combination of a first fixed seat, an adjusting component, a blocking block, a platform, a limiting device, a lifting frame, and a hydraulic rod to form a new wheel hub positioning device for automobile inspection. The operator moves the car onto the platform, where the front and rear wheels are placed on the corner plate and rear wheel tray, respectively. Two extension clips are used to hold the wheels against both sides, and then a connecting limiting component extends into the wheel, assisting the extension clips in limiting the wheels. This allows the wheels to rotate with the corner plate at the same amplitude under the action of the extension clips, enabling the corner plate to position and adjust the wheels.
