Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile measurement technology, more particularly to a positioning floating disc. BACKGROUND

[0002] After the vehicle is offline, the four-wheel alignment of the vehicle needs to be adjusted, and the automobile manufacturing factory has high requirements on the rhythm, so higher-efficiency four-wheel alignment equipment needs to be introduced for detection and adjustment, and the floating disc device of the four-wheel alignment equipment is a key component. Through the action of the floating disc, the accuracy of four-wheel alignment adjustment is improved, thereby solving the problem of whether the vehicle deviates or the tire is worn out. With the increase of vehicle types, from traditional fuel vehicles to the emergence of PHEV, EV, REV and other vehicle types, the battery is carried more and more large, the weight of the vehicle is more and more heavy, and the torque of the electric drive is more and more large. The existing floating disc of the four-wheel alignment equipment cannot meet the use of large-weight vehicle models, and a new floating disc needs to be designed to meet the use. SUMMARY

[0003] To solve the above problems, the utility model provides a positioning floating disc, which can efficiently position, detect and adjust the vehicle wheel and meet the use of large-weight vehicle models.

[0004] To solve the above technical problems, the utility model adopts the technical scheme of a positioning floating disc, which comprises a roller motor with a brake function, a floating disc and a rack. The roller motor is provided at least with two, and the two roller motors are parallel and rotatably installed on the upper surface of the floating disc. The distance between the two roller motors is less than the diameter of the vehicle wheel. The vehicle wheel is pressed on the roller motor, and the vehicle wheel is located between the two roller motors. The floating disc is rotatably installed on the rack. The upper surface of the floating disc is further provided with a brake device, which is arranged between the two roller motors. The upper end of the brake device abuts against the bottom of the roller motor. The rack is further provided with a reset device for driving the floating disc to reset.

[0005] In the technical solution, when the automobile wheel needs to be detected and adjusted, the automobile with the installed automobile wheel is driven onto the detection table so that the automobile wheel is pressed between the two roller motors, and the two roller motors are started to rotate and drive the automobile wheel to roll. If the automobile wheel is installed with deviation, the rolling direction of the automobile wheel will deviate at the same time. The roller motor is fixedly installed on the floating disc, and the floating disc is rotatably installed on the rack. The rack is used for integrating and installing various parts and protecting various parts. After the rolling direction of the automobile wheel deviates, the automobile wheel drives the roller motor to rotate, and then drives the floating disc to rotate, so as to obtain the deflection information of the automobile wheel. Then, the installation of the automobile wheel on the axle is adjusted. The reset device for driving the floating disc of the equipment to reset is arranged in the rack. When it is detected that the installation of the automobile wheel on the axle has deflection, the work of the roller motor is stopped, and then the connection between the axle and the automobile wheel is loosened. Then the reset device is started, the reset device drives the floating disc to rotate back to the correct position, the floating disc drives the roller motor to rotate and then drives the automobile wheel to rotate to the correct position, and then the connection between the automobile wheel and the axle is tightened, so as to realize the positioning of the automobile wheel. Finally, the roller motor is started again to detect the automobile wheel to determine whether the adjustment of the automobile wheel is correct. The rolling of the automobile wheel is powered by the roller motor, so that the state of the automobile wheel is easy to observe and control during the test. Even if the automobile wheel accidentally rolls out of the test position, it will stop quickly because it does not have power itself, and it is not necessary to manually start the automobile wheel to rotate by starting the engine, thereby avoiding the danger of collision caused by the displacement of the vehicle itself providing power and colliding with the floating disc. The roller motor itself has a brake function. When the vehicle weight is large, the automobile wheel has a large pressure on the roller motor. When the test is completed and the automobile needs to be driven away, the automobile wheel has a large friction force with the roller motor. When the friction force is greater than the brake force that the roller motor can provide itself, brake failure will occur, the roller motor will rotate with the automobile wheel, and the vehicle will be difficult to drive out. Therefore, an additional brake device is arranged between the two roller motors to increase the brake force, thereby avoiding the problem that the roller motor rotates with the automobile wheel and the vehicle is difficult to drive out due to the excessive weight of the vehicle.

[0024] The technical scheme of the present application will be further specifically described below by means of specific embodiments and in combination with the drawings:

[0025] Embodiment 1

[0026] As Figure 1As shown, a positioning floating disc includes drum motors 1 with brake function, a floating disc 2, a rack 3, the drum motors 1 are provided at least two, the two drum motors 1 are rotatably installed on the upper surface of the floating disc 2 in parallel, the distance between the two drum motors 1 is less than the diameter of the wheel, the wheel is pressed on the drum motor 1, the wheel is located between the two drum motors 1, the floating disc 2 is rotatably installed on the rack 3, the upper surface of the floating disc 2 is further provided with a brake device 5, the brake device 5 is provided between the two drum motors 1, the upper end of the brake device 5 abuts with the bottom of the drum motor 1, the rack 3 is further provided with a reset device 6 for driving the floating disc 2 to reset. In use, the positioning floating disc is installed on the ground, the upper surface of the floating disc 2 is flush with the ground. When it is necessary to detect and adjust the automobile wheel, the automobile is driven to the floating disc 2 so that the wheel is located between the two drum motors 1, at this time the wheel is pressed on the two drum motors 1. Start the two drum motors 1, the two drum motors 1 rotate to drive the automobile wheel to roll. If the automobile wheel deviates during installation, the rolling direction of the wheel will deviate at the same time. The drum motor 1 is installed on the floating disc 2, the floating disc 2 is slidably installed on the rack 3. The rack 3 is used for integrating and installing various parts and protecting various parts. After the rolling direction of the wheel deviates, the wheel drives the drum motor 1 to rotate, and then drives the floating disc 2 to rotate, so as to obtain the deflection information of the wheel. Then the installation of the wheel on the axle is adjusted. The reset device 6 for driving the equipment floating disc 2 to reset is arranged in the rack 3, when it is detected that the installation of the wheel on the axle has deflection, the work of the drum motor 1 is stopped, and then the connection between the axle and the wheel is loosened. Then the reset device 6 is started, the reset device 6 drives the floating disc 2 to rotate back to the correct position, the floating disc 2 drives the rolling motor to rotate and then drives the wheel to rotate to the correct position, and then the connection between the wheel and the axle is tightened, so as to realize the positioning of the wheel. Finally, the drum motor 1 is started again to detect the wheel, to determine whether the adjustment of the wheel is correct. The drum motor 1 provides power source for the rolling of the wheel, so that the state of the wheel is easy to observe and control during the test process, without manually starting the wheel to rotate through the engine, avoiding the danger of collision due to the displacement of the vehicle itself to rush out of the floating disc. The drum motor 1 itself has brake function. When the weight of the vehicle is large, the wheel has large pressure on the drum motor 1, when the test is completed and the automobile needs to be driven away, the wheel has large friction force with the drum motor 1, when the friction force is greater than the brake force that the drum motor 1 can provide itself, brake failure will occur, the rolling motor rotates with the wheel, causing the vehicle to be difficult to drive out. Therefore, the additional brake device 5 is further arranged between the two drum motors 1 to increase the brake force, avoiding the problem that the drum motor 1 rotates with the wheel due to the large weight of the vehicle, making it difficult for the vehicle to drive out.

[0027] As Figure 2As shown, the brake device 5 includes a first brake block 51 and a cylinder 52, the cylinder 52 is fixedly installed on the upper surface of the floating disc 2, the telescopic end of the cylinder 52 is upward, the first brake block 51 is installed on the telescopic end of the cylinder 52, and the first brake block 52 abuts against the bottom of the drum motor 1. When the drum motor 1 normally works, the cylinder 52 is in the retracted state, the first brake block 51 is at the lowest position, and there is a gap between the first brake block 51 and the drum motor 1, which does not affect the work of the drum motor 1. After the drum motor 1 completes the work, the cylinder 52 extends, drives the first brake block 51 to move upward, so that the first brake block 51 abuts against the outer wall surface of the drum motor 1, thereby generating a friction force to limit the rotation of the drum motor 1.

[0028] As shown in Figure 3 , 4 shown, the reset device 6 includes a driving member 61, a first reset arm 62 and a second reset arm 63, the first reset arm 62 and the second reset arm 63 are rotatably installed on the rack 3, the first reset arm 62 and the second reset arm 63 are symmetrically arranged, the first reset arm 62 is provided with a first toothed surface 66, the second reset arm 63 is provided with a second toothed surface 67, the first toothed surface 66 and the second toothed surface 67 are engaged, the driving end of the driving member 61 is connected with the first reset arm 62, the first reset arm 62 is provided with a first reset part 64, the second reset arm 63 is provided with a second reset part 65, the floating disc 2 is provided with a reset hole 21 with a symmetrical structure, the first reset part 64 and the second reset part 65 are inserted into the reset hole 21, and the floating disc 2 is reset when the first reset part 64 and the second reset part 65 abut against the hole wall of the reset hole 21. The driving member 61 is used for driving the first reset arm 62 to rotate, the first reset arm 62 and the second reset arm 63 are engaged through the first toothed surface 66 and the second toothed surface 67, thereby ensuring that the first reset arm 62 and the second reset arm 63 can synchronously rotate. The floating disc 2 is provided with a reset hole 21 with a symmetrical structure, the first reset part 64 and the second reset part 65 are inserted into the reset hole 21 for abutting against the hole wall of the reset hole 21 to drive the floating disc 2 to rotate and reset. When the floating disc 2 rotates and needs to be reset, the driving member 62 drives the first reset arm 62 to rotate and drives the second reset arm 63 to rotate. When the floating disc 2 rotates towards the direction of the first reset arm 62, the first reset part 64 will abut against the hole wall of the reset hole 21 first in the rotating process, so that the floating disc 2 rotates with the first reset arm 62, until the second reset part 65 and the first reset part 64 abut against the reset hole 21 at the same time, at this time, the floating disc 2 returns to the original position. When the floating disc 2 rotates towards the direction of the second reset arm 63, the reset can also be realized through the above process.

[0029] As shown in Figure 4As shown, the first reset part 64 is a first bearing, and the second reset part 65 is a second bearing. The inner ring of the first bearing is fixedly mounted on the first reset arm 62, and the outer ring of the second bearing is fixedly mounted on the second reset arm 63. Both the outer rings of the first and second bearings abut against the wall surface of the reset hole 21. The outer walls of both the first and second bearings can roll, preventing scratches and jamming when the first reset part 64 and the second reset part 65 abut against the wall of the reset hole 21.

[0030] Example 2

[0031] This embodiment is similar to Embodiment 1 above, except that, as Figure 1 , 5 As shown, a floating disc brake device 4 is also installed inside the frame 3. The floating disc brake device 4 includes a connecting plate 41, a second cylinder 42, a connecting rod 43, and a second brake block 44. The connecting plate 41 is fixedly installed on the bottom surface of the floating disc 2, and the second cylinder 42 is fixedly installed on the bottom surface inside the frame 3. The two ends of the connecting rod 43 are respectively connected to the driving ends of the connecting plate 41 and the second cylinder 42. The second brake block 44 is fixedly installed inside the frame 3 and located directly above the connecting plate 41. When a vehicle drives over the floating disc, the floating disc 2 may rotate under the action of the vehicle's gravity, so a floating disc brake device is required. When it is necessary to limit the rotation of the floating disc 2, the second cylinder 52 extends, which in turn drives the connecting plate 41 to move upward through the connecting rod 43, so that the connecting plate 41 abuts against the second brake block 44. The friction between the connecting plate 41 and the second brake block 44 achieves the effect of limiting the rotation of the floating disc 2.

[0032] like Figure 5 As shown, the second brake block 44 is also equipped with a return spring for pushing the connecting plate 41 back to its original position. When it is necessary to release the fixation of the floating disc 2, the second cylinder 42 loses its supporting function on the connecting plate 41, and under the action of the return spring, pushes the connecting plate 41 back to its original position.

[0033] Example 3

[0034] This embodiment is similar to Embodiment 1 above, except that, as Figure 1 As shown, a sensor 7 is also installed inside the frame 3, and the sensor 7 abuts against the bottom surface of the floating disk 2. The sensor 7 can directly detect the rotation of the floating disk 2 and transmit the relevant information to the external controller, eliminating the need for manual measurement and reducing the workload of the staff.

[0035] like Figure 1 As shown, a set screw 8 is also fixedly installed inside the frame 3, and the set screw 8 abuts against the sensing plate 7. The set screw 8 provides auxiliary support for the sensing plate 7 and prevents the sensing plate 7 from becoming loose.

[0036] As Figure 1 、 4 shown, the rack 3 is further provided with a weight measuring device 9, the top surface of the weight measuring device 9 is in abutment with the bottom surface of the floating disc 2. Through the weight detection device 9, the weight of the automobile can be measured and the floating disc 2 is assisted to support

[0037] As Figure 1 、 4 shown, the top of the weight measuring device 9 is rollably installed with a ball 91, the ball 91 is in abutment with the bottom surface of the floating disc 2. Through the setting of the ball 91, while meeting the supporting effect of the floating disc 2, the ball 81 can also roll when the floating disc 2 rotates, the sliding friction is converted into rolling friction, so that the bottom surface of the floating disc 2 is scratched and the normal rotation of the floating disc 2 is affected.

[0038] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or changes can be made.
