Description

Technical Field

[0001] This utility model belongs to the field of automotive parts testing technology, and more specifically, it relates to a dual-station verticality inspection platform for the left and right rear wheel brackets. Background Technology

[0002] When conducting final quality inspection of the rear wheel suspension system before the vehicle leaves the factory, a dual-station verticality inspection platform for the left and right rear wheel brackets is required to perform high-precision testing of the verticality of the left and right rear wheel brackets. This ensures that the verticality of the brackets meets the design standards and avoids safety hazards such as vehicle deviation and uneven tire wear caused by excessive errors.

[0003] Based on the above, the current inspection platform uses fixed fixtures, which are inconvenient to quickly and adaptively fix according to different types of supports, lack a stable clamping and testing structure, and are inconvenient for rotating and testing verticality. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dual-station verticality inspection platform for the left and right rear wheel brackets. This solves the problems mentioned in the background art, where existing inspection platforms use fixed fixtures, making it inconvenient to quickly and adaptively fix them according to different types of brackets, lacking a stable clamping and detection structure, and making it inconvenient to perform rotational verticality inspections.

[0005] The purpose and effectiveness of this utility model, a dual-station verticality inspection platform for the left and right rear wheel supports, are achieved through the following specific technical means: A dual-station verticality inspection platform for rear wheel left and right supports includes an installation platform. Two sets of electric push rods are fixedly installed on both sides of the top of the installation platform. Two sets of moving detectors are slidably installed on both sides of the top of the installation platform, and the telescopic ends of the electric push rods are fixed to the rear of the moving detectors. A shaft cylinder is rotatably installed above the adjacent surfaces of the two sets of moving detectors, and a rotating row is fixedly installed at the adjacent ends of the two sets of shaft cylinders. A set of indicator lights and a row of infrared ranging probes are fixedly installed outside the rotating row. A lifting frame is fixedly installed on the rear top of the installation platform, and a lifting frame is slidably installed on the front side of the lifting frame. Two sets of F-shaped frames for positioning are fixedly installed at both ends of the front side of the lifting frame.

[0006] Furthermore, each of the moving detectors is fixedly equipped with a servo motor on its top, and the servo motor is connected to the shaft cylinder by a bevel gear transmission; the indicator spotlight is aligned with the shaft cylinder axis.

[0007] Furthermore, a lead screw is rotatably provided on the front side of the lifting frame, a drive motor for driving the lead screw is provided on the top of the lifting frame, and a nut is provided on the rear side of the lifting frame for threaded connection with the lead screw.

[0008] Furthermore, a telescopic hydraulic cylinder A is fixedly installed at the upper center of each of the F-shaped frames, and a clamping plate A is fixedly installed at the telescopic end of the telescopic hydraulic cylinder A; the lower end of the F-shaped frame turns upward at the front and upper; a telescopic hydraulic cylinder B is fixedly installed below the adjacent surfaces of the two sets of F-shaped frames, and a clamping plate B is fixedly installed at the telescopic end of the telescopic hydraulic cylinder B; a vertical seat is fixedly installed at the rear between the two sets of F-shaped frames.

[0009] Furthermore, two sets of telescopic hydraulic cylinders C are fixedly installed on the rear side of the vertical base, and clamping plates C are fixedly installed on the telescopic ends of the telescopic hydraulic cylinders C; two sets of guide piles are fixedly installed on the upper front of the vertical base, and clamping plates C slide under the guide piles in cooperation with guide rails.

[0010] Furthermore, an oil tank is fixedly installed on the front side of the vertical base, an adjustment hole is opened above the oil tank, an oil pump is connected to the bottom of the oil tank, and a solenoid valve is connected to the other end of the oil pump. The other end of the solenoid valve is connected to a pipe that connects to telescopic cylinder A, telescopic cylinder B and telescopic cylinder C.

[0011] Furthermore, a level is fixedly installed on the front side of the lifting frame and below the adjacent surfaces of the two sets of F-shaped frames. The level is made of transparent PVC material with a raised center and graduations on the outside.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The adaptive clamping system is highly adaptable, overcoming the limitations of fixed tooling. It breaks through the problem that traditional fixed tooling can only adapt to a single type of bracket. Through the use of telescopic cylinder A and clamping plate A to achieve vertical clamping, telescopic cylinder B and clamping plate B to achieve horizontal positioning, and telescopic cylinder C and clamping plate C to achieve front and rear limit, the system can stably clamp rear wheel brackets of different sizes and structures in three dimensions. It eliminates the need for frequent disassembly and assembly of tooling, greatly improving the flexibility and efficiency of testing multiple bracket models.

[0013] The rotary inspection system is precise and efficient, ensuring the quality of verticality testing. An innovative design features a servo motor driving a bevel gear to rotate the shaft cylinder. A rotating platform on the outside of the shaft cylinder rotates synchronously with it. An infrared ranging probe at the end of the platform can circle the rear wheel for inspection. Combined with a calibration method that uses indicator lights for positioning and an electric push rod for fine-tuning the inspection position, it can accurately capture verticality data at different positions of the rear wheel. Simultaneously, a preset program ensures the shaft cylinder rotates in the opposite direction after each revolution, preventing wire entanglement and guaranteeing both inspection accuracy and ease of operation.

[0014] Multi-stage status monitoring reduces the risk of detection errors. On the one hand, the drive motor rotates the lead screw, and the lifting frame on the outside of the lead screw moves up and down with the lead screw, which can accurately adjust the detection height of the support and ensure the consistency of the detection benchmark. On the other hand, transparent PVC level instruments are set at key positions of the lifting frame and F-shaped frame. Before each test, the position of the bubble can be observed to quickly determine whether the platform is level and whether the F-shaped frame is deformed, so as to avoid detection errors caused by abnormal equipment status in advance and ensure the reliability of the test results.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] Example 1: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a dual-station verticality inspection platform for the left and right rear wheel supports, including an installation platform 1. Two sets of electric push rods 101 are fixedly installed on the top two sides of the installation platform 1. Two sets of moving detectors 2 are slidably installed on the top two sides of the installation platform 1, and the telescopic ends of the electric push rods 101 are fixed to the rear side of the moving detectors 2. A shaft cylinder 202 is rotatably installed above the adjacent surfaces of the two sets of moving detectors 2. A rotating row 203 is fixedly installed at the adjacent ends of the two sets of shaft cylinders 202. A set of indicator lights 204 and a row of infrared ranging probes 205 are fixedly installed outside the rotating row 203. A lifting frame 3 is fixedly installed on the top rear side of the installation platform 1, and a lifting frame 4 is slidably installed on the front side of the lifting frame 3. Two sets of F-shaped frames 401 for positioning are fixedly installed at both ends of the front side of the lifting frame 4. The infrared ranging probes 205 synchronously collect distance data at different circumferential positions of the rear wheel during inspection. The equipment has a built-in data processing module to compare the collected distance data with preset standard values.

[0023] The top of each of the moving detectors 2 is fixedly equipped with a servo motor 201, and the servo motor 201 is connected to the shaft cylinder 202 by a bevel gear transmission; the indicator spotlight 204 is aligned with the axis of the shaft cylinder 202.

[0024] The lifting frame 3 has a lead screw 301 rotatably mounted on the front side, a drive motor 302 for driving the lead screw 301 mounted on the top of the lifting frame 3, and a nut for threaded connection with the lead screw 301 mounted on the rear side of the lifting frame 4.

[0025] Among them, a telescopic hydraulic cylinder A402 is fixedly installed in the middle of the upper part of the F-shaped frame 401, and a clamping plate A403 is fixedly installed at the telescopic end of the telescopic hydraulic cylinder A402; the lower end of the F-shaped frame 401 turns upward in front; a telescopic hydraulic cylinder B404 is fixedly installed below the adjacent surfaces of the two sets of F-shaped frames 401, and a clamping plate B405 is fixedly installed at the telescopic end of the telescopic hydraulic cylinder B404; a vertical seat 5 is fixedly installed at the rear between the two sets of F-shaped frames 401.

[0026] Two sets of telescopic hydraulic cylinders C501 are fixedly installed on the rear side of the vertical base 5, and clamping plates C502 are fixedly installed on the telescopic ends of the telescopic hydraulic cylinders C501; two sets of guide piles 503 are fixedly installed on the upper front of the vertical base 5, and the clamping plates C502 slide under the guide piles 503 in cooperation with the guide rail.

[0027] Among them, an oil tank 504 is fixedly installed on the front side of the vertical base 5. An adjustment hole is opened above the oil tank 504. An oil pump 6 is connected to the bottom of the oil tank 504. The other end of the oil pump 6 is connected to a solenoid valve 7. The other end of the solenoid valve 7 is connected to a pipe that connects to the telescopic cylinder A402, the telescopic cylinder B404 and the telescopic cylinder C501.

[0028] Among them, a level 8 is fixedly installed on the front side of the lifting frame 4 and below the adjacent surfaces of the two sets of F-shaped frames 401. The level 8 is a transparent PVC material with a raised center and graduations on the outside, and is filled with damping fluid and retains air bubbles.

[0029] Bracket full-angle fixation operation Preparation phase: After confirming that the F-shaped frame 401 is in the initial closed state and there are no parts obstructing it, place the bracket to be tested stably in the support area inside the F-shaped frame 401, ensuring that the bracket is aligned with the positioning reference of the F-shaped frame 401 and the initial positioning is stable. Start the hydraulic system: Open the control switch on the side of the F-shaped frame 401 to trigger the oil pump 6 to run. The oil pump 6 delivers hydraulic oil to the hydraulic pipeline. Through the pipeline distribution, the telescopic cylinders A402, B404 and C501 simultaneously obtain hydraulic power and slowly and synchronously open. Complete clamping and fixing: As telescopic cylinders A402, B404, and C501 extend, the clamping plates A403, B405, and C502 connected to their ends gradually approach the bracket until they are tightly attached to the bracket surface, forming clamping force from multiple directions (up, down, left, and right) to complete the full-angle fixing of the bracket. Locking hydraulic state: After fixing, close solenoid valve 7 to cut off the return channel of hydraulic oil. The locking function of the hydraulic system maintains the current clamping state of the clamping plate to prevent the bracket from shifting or loosening during subsequent height adjustment and testing.

[0030] II. Bracket Height Adjustment Operation Start the height adjustment power: Press the lifting control button to start the drive motor 302. The rotational power output by the drive motor 302 is transmitted to the lead screw 301 through the coupling, causing the lead screw 301 to start rotating clockwise or counterclockwise. Performing height adjustment action: When the lead screw 301 rotates, the nut seat engaged on its outer side drives the lifting frame 4 to move up and down along the axis of the lead screw 301. The lifting frame 4 is rigidly connected to the F-shaped frame 401, and synchronously drives the fixed bracket to move up and down. Stop adjusting and positioning: Observe the height scale or the height display of the detection system. When the bracket reaches the target height for the rear wheel detection, press the control button again to stop the drive motor 302 from running, the lead screw 301 will stop rotating, and the lifting frame 4 and the bracket will remain at the current height position. III. Calibration of Detection Position and Verticality Detection of Rear Wheels Adjusting the lateral position of the detection device: Activate the control switch of the electric push rod 101. The piston rod of the electric push rod 101 extends and retracts axially, driving the movable detector 2 connected to the end of the piston rod to slide back and forth along the guide rail. Based on the lateral position of the rear wheel, the lateral coordinate of the movable detector 2 is precisely adjusted. Complete the detection and positioning calibration: Based on the height determined in the "Hall Height Adjustment Operation", adjust the electric push rod 101 or drive motor 302 to make the center line of the wheel axle of the rear wheel to be tested completely aligned with the light emitted by the indicator spotlight 204 installed at the front end of the moving detector 2. At this time, the position of the moving detector 2 is the optimal detection position, and the positioning calibration is completed. Start the detection drive mechanism: After positioning and calibration, start the servo motor 201. The output shaft of the servo motor 201 changes the transmission direction through the bevel gear pair, driving the shaft cylinder 202 to rotate around its own axis. Perform rotational detection: When the shaft cylinder 202 rotates, the rotating blocks 203 evenly distributed on its outer circumference rotate synchronously with the shaft cylinder 202. The infrared ranging probe 205 installed at the end of the rotating blocks 203 moves in a circle with the rotating blocks 203, continuously emitting infrared signals to the rear wheel surface and receiving reflected signals. The distance between the infrared ranging probe 205 and the rear wheel surface is calculated by the signal processing module, and the rear wheel is judged to be perpendicular based on the distance data at different positions. Protection against wire entanglement: The rotation logic of the shaft cylinder 202 is set through the preset program of the equipment control system. After each complete rotation (360°), the servo motor 201 automatically reverses, driving the shaft cylinder 202 to rotate in the opposite direction, so as to prevent the wires connecting the infrared ranging probe 205 and the servo motor 201 inside the moving detector 2 from being entangled, pulled or damaged due to continuous unidirectional rotation. Example 2: Horizontal monitoring and equipment status assessment Preoperative level check: Before each installation of the bracket to be tested, observe the level 8 installed on the side of the equipment platform and check whether the bubble inside the level 8 is within the range of the middle scale line to determine whether the platform is in a level state. Normal state judgment: If the bubble of the level 8 is located at the middle scale line, it means that the F-shaped brackets 401 on both sides are not bent or deformed, the equipment platform is level as a whole, meets the testing requirements, and the subsequent bracket installation, fixing and testing operations can be started normally. Abnormal status handling: If the bubble of the level 8 deviates from the middle scale line (leaning to the left or right), it indicates that one or both sides of the F-shaped frame 401 are deformed (such as bent or tilted), causing the platform to be uneven. At this time, subsequent operations should be stopped, and the deformed position of the F-shaped frame 401 should be checked (such as loose connection parts or bent support body). The F-shaped frame 401 should be repaired by replacing parts and correcting deformation. Post-repair check: After the F-shaped bracket 401 is repaired, observe the position of the bubble on the level 8 again. Only after confirming that the bubble has returned to the middle scale line and the platform has returned to a level state can the bracket to be tested be installed and subsequent testing operations be carried out again. The specific usage and function of this embodiment are as follows: In this utility model, when in use, according to Figure 1 The bracket is placed in the F-shaped frame 401, the F-shaped frame 401 is opened and the oil pump 6 is started to supply oil, the telescopic cylinders A402, B404 and C501 are opened, and the bracket is fixed at all angles by the clamps A403, B405 and C502; the solenoid valve 7 is closed to keep it fixed. Then start the drive motor 302 to drive the lead screw 301 to rotate, and adjust the lifting frame 4 and the height of the support; The electric push rod 101 is activated to move the mobile detector 2 back and forth, adjusting its detection position. Further adjustments are made upside down and forward and backward to align the rear wheel axle with the indicator light 204. At this point, the servo motor 201 is activated, driving the axle cylinder 202 and the turntable 203 to rotate via bevel gears. The infrared ranging probe 205 performs a cyclic detection of the rear wheel to determine if it is perpendicular. Through program constraints, the axle cylinder 202 rotates in the opposite direction after each revolution to prevent wiring tangling. The level 8 provides a level monitoring function to prevent deformation of the F-shaped brackets 401 on both sides, which would cause unevenness on the left and right sides of the bracket. By observing whether the level is normal before each bracket installation, it can be determined whether the platform can perform normal testing.
