Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts life testing devices, and in particular to a multi-station automotive parts life testing device. Background Technology

[0002] As a core component of vehicle driving safety and user experience, the lifespan and reliability of automotive parts need to be verified through professional testing equipment. Among them, windshield wipers, as a core component for ensuring visibility while driving in rainy weather, need their lifespan test to simulate the actual working condition of "wipers wiping the glass back and forth".

[0003] Traditional methods for testing the lifespan of automotive windshield wipers primarily involve installing the wipers at corresponding workstations on testing equipment. Since wipers require batch sampling testing before leaving the factory (typically testing 3-6 or even more samples simultaneously to ensure data representativeness), the testing components of traditional testing devices are usually arranged in a single row. This layout has significant drawbacks: firstly, a single-row layout requires a considerable amount of horizontal space, which is significantly limited by the size of the workshop, especially when multiple devices are deployed in parallel, easily leading to crowded workshop layouts and reduced overall space utilization; secondly, during inspection and maintenance, staff must operate along a single row of workstations one by one, resulting in long operating paths and increased workload. To address these issues, this invention proposes a multi-workstation automotive parts lifespan testing device. Utility Model Content

[0004] The main objective of this invention is to provide a multi-station automotive parts life testing device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-station automotive parts life testing device includes a control frame and a mounting base. A vertical rod is rotatably connected to the upper end of the mounting base, and a connecting plate is fixedly connected to the upper end of the vertical rod. A worktable is provided on the upper end of the connecting plate. Multiple mounting mechanisms for installing windshield wipers are provided on the worktable. Each mounting mechanism includes a mounting frame disposed on the worktable. A glass is provided on the side wall of the mounting frame. A rotating shaft is rotatably connected to the side wall of the mounting frame. A windshield wiper mounting bracket is fixedly connected to the side wall of the rotating shaft. A first drive assembly is mounted on the side wall of the mounting frame. A controller is mounted on the control frame. The worktable is connected to the connecting plate through a connecting mechanism.

[0006] Preferably, the connecting mechanism includes a plurality of second screws fixedly connected to the lower end of the workbench, and the sidewalls of the second screws are threaded with second nuts.

[0007] Preferably, a plurality of first screws are fixedly connected to the upper end of the workbench, and a first nut is threadedly connected to the side wall of the first screw, with the upper end of the first screw penetrating the upper end of the adjacent mounting frame.

[0008] Preferably, the glass sidewall is fitted with a placement frame, the placement frame is fixedly connected to an adjacent mounting frame, the inner wall of the mounting frame is fixedly connected to two fixing brackets, the sidewall of the fixing bracket is provided with a threaded rod, one end of the threaded rod is rotatably connected to a clamping block, and the other end of the threaded rod is fixedly connected to a handwheel.

[0009] Preferably, a second drive assembly is fixedly connected to the upper end of the mounting base plate, and a first gear and a second gear are fixedly connected to the side wall of the vertical rod and the side wall of the second drive assembly, respectively, with the first gear and the second gear meshing with each other.

[0010] Preferably, a transparent plate is fixedly connected to the upper end of the mounting frame, and two placement slots are formed on the side wall of the transparent plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This device is equipped with an installation mechanism that arranges multiple installation frames around the workbench. While achieving multiple workstations, it significantly reduces the equipment footprint and improves the utilization rate of workshop space. At the same time, it shortens the inspection path for staff and solves the drawbacks of traditional devices caused by a single-row layout, such as "large space occupation and low operating efficiency". This device is equipped with a connecting mechanism. The cooperation between the second screw and the connecting plate enables the worktable to be disassembled, and the first screw enables the mounting frame to be disassembled. The disassembled components are small in size and light in weight, and can be loaded and unloaded without large transportation equipment. This solves the problems of "inconvenient transportation and poor flexibility" of traditional integrated testing devices, and reduces transportation and storage costs. This device is equipped with a fixed frame, threaded rod, clamping block and placement frame, which enables independent and detachable replacement of glass without disassembling the installation frame, greatly improving replacement efficiency. It solves the problems of "cumbersome maintenance and long downtime after glass damage" of traditional devices, reducing maintenance costs and test interruption risks. This device is equipped with a transparent plate and a placement slot to classify and store wiper information and equipment component maintenance records. This allows staff to quickly trace test data and maintenance history, solving the problem of "chaotic test information management and difficulty in tracing" in traditional devices and improving the standardization of the testing process.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-5 As shown, a multi-station automotive parts life testing device includes a control frame 1 and a mounting base 2. A vertical rod 3 is rotatably connected to the upper end of the mounting base 2, and a connecting plate 19 is fixedly connected to the upper end of the vertical rod 3. A worktable 4 is provided on the upper end of the connecting plate 19. It is worth noting that the rotation range of the worktable 4 does not exceed 360 degrees to avoid cable entanglement.

[0016] The workbench 4 is equipped with multiple mounting mechanisms for installing windshield wipers. Each mounting mechanism includes a mounting frame 5 on the workbench 4, with glass 7 on the side wall of the mounting frame 5. A rotating shaft 15 is rotatably connected to the side wall of the mounting frame 5, and a windshield wiper mounting bracket 16 (the windshield wiper mounting bracket 16 is a component for installing windshield wipers on existing automobiles, and its structure is existing technology) is fixedly connected to the side wall of the mounting frame 5. A first drive assembly 14 (the first drive assembly 14 is a common windshield wiper driver, including a transmission box and a motor) is installed on the control frame 1. A controller 8 is installed on the control frame 1. The workbench 4 is connected to the connecting plate 19 through a connecting mechanism.

[0017] In this utility model, the connecting mechanism includes a plurality of second screws 20 fixedly connected to the lower end of the workbench 4. The side wall of the second screw 20 is threaded with a second nut. The lower end of the connecting plate 19 has a plurality of holes for the second screws 20 to pass through, so that the workbench 4 and the vertical rod 3 can be detachably connected for easy transportation.

[0018] In this utility model, a plurality of first screws 9 are fixedly connected to the upper end of the workbench 4, and a first nut is threadedly connected to the side wall of the first screw 9. The upper end of the first screw 9 passes through the upper end of the adjacent mounting frame 5, so that multiple mounting mechanisms can be disassembled, which facilitates the disassembly, transportation and maintenance of the equipment.

[0019] In this utility model, a placement frame 17 is fitted on the side wall of the glass 7. The placement frame 17 is fixedly connected to the adjacent mounting frame 5. Two fixing brackets 6 are fixedly connected to the inner wall of the mounting frame 5. A threaded rod 10 is provided through the side wall of the fixing bracket 6. One end of the threaded rod 10 is rotatably connected to a clamping block 11, and the other end of the threaded rod 10 is fixedly connected to a handwheel, so that the glass 7 can be disassembled and the damaged glass 7 can be replaced individually.

[0020] In this invention, a second drive assembly 18 (a motor whose output shaft can rotate in both directions) is fixedly connected to the upper end of the mounting base plate 2. A first gear and a second gear are fixedly connected to the side wall of the vertical rod 3 and the side wall of the second drive assembly 18, respectively. The first gear and the second gear mesh with each other. The second drive assembly 18 (motor) drives the second gear to rotate, and then the meshing first gear drives the vertical rod 3 to rotate, thereby driving the worktable 4 to rotate. There is no need for manual pushing of the worktable 4. The staff can complete multi-station inspection and operation in a fixed position, reduce the operation path, and improve the convenience of the testing process.

[0021] In this utility model, a transparent plate 12 is fixedly connected to the upper end of the mounting frame 5. Two placement slots 13 are opened on the side wall of the transparent plate 12. The transparent plate 12 is made of acrylic sheet material (which has both light transmission and wear resistance), so that it does not obstruct the observation of the wiper test status and can protect the internal structure of the mounting frame 5. The two placement slots 13 respectively store wiper information and equipment component maintenance records, which can realize the management of "one file per workstation", making it convenient for staff to quickly trace the wiper source, test progress and equipment maintenance history, and improve the standardization of test management.

[0022] In the idle position of this device, all the above-mentioned driving components (referring to power elements and electrical components) and the appropriate power supply are connected by wires. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are well known in the field. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0023] During use, the principles behind wiper installation, multi-station testing, and space utilization are as follows: First, the wiper to be tested is fixed in place using the wiper mounting bracket 16 (the wiper mounting bracket 16 is compatible with the installation interface of existing car wipers and can accommodate wipers of different lengths and models). Each mounting frame 5 corresponds to an independent test station. According to the number of samples to be tested, the wipers are installed in multiple mounting frames 5 on the workbench 4. Then, the test parameters (such as wiper reciprocating frequency, total test duration, stop threshold, etc.) are set by the controller 8, and the first drive assembly 14 is started. The motor inside the first drive assembly 14 transmits power to the rotating shaft 15 through the transmission box, causing the rotating shaft 15 to rotate reciprocally, thereby driving the wiper on the wiper mounting bracket 16 to perform reciprocating wiping motion along the surface of the glass 7, simulating the actual use conditions of car wipers in rainy weather. The controller 8 collects test data in real time (such as the number of wiping strokes, indirect feedback signals of wiper blade wear, etc., and the various sensors involved are not shown in the figure). Because multiple mounting frames 5 are arranged in a ring (or distributed) around the workbench 4 (replacing the traditional "line-up" arrangement), the overall footprint of the device is only 1 / 3 to 1 / 2 of the traditional single-row layout (adjusted according to the number of workstations) while enabling simultaneous testing of 3 or more workstations, significantly improving workshop space utilization. At the same time, the second drive assembly 18 is activated, which drives the second gear to rotate. Through the meshing first gear, the vertical rod 3 is driven to rotate slowly (rotation amplitude not exceeding 360 degrees to avoid wire entanglement). The vertical rod 3 drives the workbench 4 to rotate through the connecting plate 19. The staff can observe the wiper test status of all workstations through the rotating workbench 4 without moving their position, improving inspection efficiency by more than 50%. The principle behind the detachable workbench and mounting frame for convenient transportation: When the device needs to be moved from the production workshop to the storage area, or transported to different factory areas for use, first unscrew the second nut on the side wall of the second screw 20, and pull the second screw 20 at the lower end of the workbench 4 out of the hole in the connecting plate 19, so as to separate the workbench 4 from the vertical rod 3 and the mounting base 2 (the vertical rod 3 is fixed to the mounting base 2). The separated workbench 4 and the base (mounting base 2 and vertical rod 3) can be loaded separately, avoiding the problem of "large volume and large transportation equipment" of traditional integrated devices. If it is necessary to further reduce the transportation volume, the first nut on the side wall of the first screw 9 can be unscrewed to remove the individual mounting frame 5 from the workbench 4. The separated mounting frame 5, workbench 4, base and other components are all small parts and lightweight (the weight of a single component does not exceed 20kg). They can be loaded and unloaded by ordinary forklifts or manual labor, reducing transportation costs and handling difficulty, and reducing the risk of damage caused by component collisions during transportation. The maintenance principle of removable and replaceable glass: During long-term testing, the wiper blades will repeatedly rub against the surface of the glass 7, causing scratches and reduced light transmittance, which affects the observation of the wiper blade's wiping effect during testing (such as whether there is wiping residue, abnormal noise, etc.). In this case, it is not necessary to disassemble the entire mounting frame 5. Simply turn the handwheel at one end of the threaded rod 10 on the side wall of the fixing bracket 6. The threaded rod 10 rotates in the threaded hole of the fixing bracket 6, which drives the clamping block 11 connected to one end to move away from the glass 7, releasing the clamping force on the glass 7. Since the side wall of the glass 7 is fitted into the placement frame 1 Inside frame 7 (where the placement frame 17 is fixed to the mounting frame 5, providing a horizontal limit for the glass 7), the damaged glass 7 can be directly pulled out from the placement frame 17. Place the new glass 7 into the placement frame 17, and turn the handwheel in the opposite direction to push the threaded rod 10 to push the clamping block 11 to clamp the glass 7 again, thus completing the replacement of the glass 7. The entire process only takes 5-10 minutes, which is much faster than the traditional 1-2 hours of "disassembling the mounting frame to replace the glass". Moreover, it does not require professional maintenance personnel and can be operated by ordinary workers, reducing the maintenance threshold and downtime.
