Then, by driving a second slider, a corresponding sliding frame slides on a second slide rail, causing the detection ends of the angle sensors mounted on the sliding frame to abut against the testing clamps.

Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a testing device for a rear axle housing assembly. Background Technology

[0002] As a key load-bearing and force-transmitting component of the vehicle's drive axle, the manufacturing and assembly precision of the rear axle housing directly affects the vehicle's transmission efficiency, handling stability, and service life. Due to its complex structure, the rear axle housing assembly is typically assembled from the main body, brakes mounted at both ends, wheel hubs, and other components. The relative position and angular accuracy between these components, particularly the symmetry, coaxiality, and installation angles between the main body and the side components, are core indicators for ensuring the rear axle assembly meets performance standards. Currently, the inspection of the rear axle housing assembly's angles largely relies on traditional testing fixtures combined with dial indicators, angle gauges, and other general measuring tools for manual measurement. This method has significant drawbacks: the testing process is cumbersome and fails to meet the requirements of modern production lines in terms of testing speed. Utility Model Content

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-5 This utility model provides a testing device for a rear axle housing assembly, including a movable frame 1. The movable frame 1 is equipped with a testing component for detecting angles. The testing component includes a clamping mechanism, a sliding frame 3, and a lock. The clamping mechanism includes two sets of testing clamps 2 symmetrically arranged on the movable frame 1. The testing clamps 2 are mounted on the movable frame 1 via a support frame, and the testing pattern slots on the testing clamps 2 can engage with the accessories of the rear axle housing assembly. The sliding frame 3 is slidably connected to the movable frame 1, and the sliding frame 3 is equipped with multiple angle sensors 4 for detecting angles. During the movement of the sliding frame 3, the detection end of each angle sensor 4 abuts against the testing clamp 2. The lock is assembled to lock the main body of the rear axle housing assembly.

[0020] The lock includes locking mechanisms symmetrically arranged on the movable frame 1. Each locking mechanism includes a support platform 5 fixedly connected to the movable frame 1; a positioning platform 6 is disposed on the support platform 5, and a connecting rod 7 is rotatably connected to the positioning platform 6. The connecting rod 7 is provided with a locking part for locking the main body of the rear axle housing assembly; a pneumatic clamp 8 is rotatably connected to the positioning platform 6, and an adapter foot 9 is rotatably connected to the telescopic end of the pneumatic clamp 8. The adapter foot 9 is rotatably connected to the connecting rod 7. It should be noted that a limiting bracket 22 is fixedly connected to each positioning platform 6, which is used to limit the shaking of the main body of the rear axle housing assembly when it is initially placed, so that the locking part can lock better later. Preferably, one support platform 5 is slidably connected to the positioning platform 6, and the other support platform 5 is fixedly connected to the positioning platform 6. The locking part includes a screw 10 threadedly connected to the connecting rod 7, and a locking head 11 fixedly connected to the screw 10 for abutting and locking the main body of the rear axle housing assembly. Specifically, the screw 10 can be adjusted to adapt to the main body of different rear axle housing assemblies, thereby achieving better locking when the pneumatic clamp 8 is opened and closed.

[0021] The support platform 5 is fixedly connected to a first slide rail 12, and a first slider 13 is slidably connected to the first slide rail 12. The first slider 13 is fixedly connected to the corresponding positioning platform 6. The movable frame 1 is provided with a second slide rail 14, and a second slider 15 is slidably connected to the second slide rail 14. The second slider 15 is fixedly connected to the corresponding sliding frame 3. In a preferred embodiment, the first slide rail 12 and the first slider 13, and the second slide rail 14 and the second slider 15 are all electrically driven components, and are electrically connected to a controller 17 (described later) to achieve sliding under the control of the controller 17.

[0022] The movable frame 1 is fixedly connected to a protective cover 16 to protect the testing mechanism.

[0023] The movable frame 1 is equipped with an electronic control module, which includes a controller 17, a display screen 18, a detection button 19, and a calibration button 20. The display screen 18, the detection button 19, and the calibration button 20 are all electrically connected to the controller 17 and work in coordination under the control of the controller 17. Each angle sensor 4 is electrically connected to the display screen 18 so that the detection values ​​are displayed on the display screen 18.

[0024] The movable frame 1 is equipped with a manual valve 21 for controlling the opening and closing of the pneumatic clamp 8.

[0025] Specifically, all the above components can work in coordination under the control of controller 17, and the workflow is as follows: First, the main body of the rear axle housing assembly is assembled onto the positioning platform 6 using external equipment, and limited by the limiting bracket 22, so that the side fittings of the main body of the rear axle housing assembly are assembled into the detection model slots of the detection plate 2. Then, by driving the second slider 15, the corresponding sliding frame 3 slides on the second slide rail 14, so that the detection ends of the angle sensors 4 set on the sliding frame 3 abut against the detection plate 2, which is used to detect the clearance tolerance between the detection model slot and the fittings. Thus, the product is tested for qualification. This process is simple and clear, improving testing efficiency while ensuring qualified quality.

[0026] Furthermore, by driving the sliding engagement between the first slide rail 12 and the slider, the positioning stage 6 can be repositioned, thereby facilitating the locking of the rear axle housing assembly body of different models for subsequent testing.

[0027] Based on the above, it should be noted that the detection in this embodiment includes two types of machines. Before performing the above operation, the two side plate mechanisms should be put into working state so that the sensor (angle sensor 4) slides to a machine location under the control of the controller 17. Then, the calibration button 20 should be pressed to automatically calibrate through the program (recalibration is required after the equipment is powered off).

[0028] During preparation, all mechanisms should be in a non-operating state, and the product should be wiped clean before loading. After placing the product on the limiting bracket 22 (taking model 1 as an example), the locking operation is completed by using the manual valve 21, and the product barcode is scanned. Then, the detection button 19 is pressed to complete the above detection process. The program will automatically calculate the angle value and display it. If it is NG, the buzzer alarm will sound (the buzzer alarm is existing technology, which is electrically connected to the controller and works in coordination under the control of the controller 17). After completion, the sliders of the two side sensors are moved to the non-operating state, and the lock is opened to remove the product. Furthermore, the second slide rail and the second slider are set to facilitate switching between models.

[0029] Furthermore, throughout the entire process, the operator must stand on the operator's side as shown in the diagram when using the equipment and loading / unloading parts to avoid unnecessary collisions and interference between people and machines.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
