Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball head wear detection technology, specifically an automatic ball head wear detection mechanism. Background Technology
[0002] Ball joints, as key components for achieving multi-angle rotation, buffering, or connection, are widely used in many fields, such as the common ball joint structure.
[0003] Wear on the ball head directly affects the performance of the equipment. At best, it can lead to a decrease in the accuracy of the equipment and the generation of abnormal noise. At worst, it can cause equipment failure or even safety accidents.
[0004] Currently, there are two main methods for ball joint wear detection. One is manual inspection, where inspectors judge the degree of wear by visual observation, touch, and measurement using simple tools. The other is a traditional automatic detection mechanism, which uses a certain mechanical structure and sensors to detect ball joint wear, but it has certain limitations in terms of detection accuracy, adaptability, and functional comprehensiveness.

[0009] A clamping groove is provided on the right side of the upper surface of the turntable. A sliding clamping block is slidably connected in the clamping groove. An adjusting screw is screwed to the right side wall of the turntable. The left end of the adjusting screw is rotatably connected to the right side wall of the sliding clamping block. A clamping area for clamping the ball head to be tested is formed between the left side wall of the sliding clamping block and the left side inside the clamping groove. The image acquisition camera is facing the standard ball head and the ball head to be tested.
[0010] Preferably, a background shield is longitudinally provided on the left end of the upper surface of the support platform.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] Example 1:
[0024] Please see Figure 1-3 This utility model provides a technical solution: an automatic ball head wear detection mechanism, comprising: a support platform 3, a turntable 7, a standard ball head component 11, and an image acquisition camera 13;
[0025] The turntable 7 is rotatably mounted on the support platform 3, the standard ball head component 11 is longitudinally mounted on the upper surface of the support platform 3, and the image acquisition camera 13 is located on the outside of the support platform 3. A clamping groove 8 is provided on the right side of the upper surface of the turntable 7, and a sliding clamping block 9 is slidably connected in the clamping groove 8. An adjusting screw 10 is screwed to the right side wall of the turntable 7, and the left end of the adjusting screw 10 is rotatably connected to the right side wall of the sliding clamping block 9. A clamping area for clamping the ball head to be tested is formed between the left side wall of the sliding clamping block 9 and the left side inside the clamping groove 8, and the image acquisition camera 13 faces the standard ball head component 11 and the ball head to be tested.
[0026] Analysis of the above content: When using it, follow... Figure 1 The structure, including the bearing platform 3, turntable 7, standard ball head component 11, and image acquisition camera 13, is assembled in this manner. The bottom end of the ball head to be tested is placed in the clamping area. At this time, the center of the ball head to be tested, the center of the standard ball head component 11, and the lens of the image acquisition camera 13 are at the same height. Thus, the image acquisition camera 13 takes pictures of the standard ball head component 11 and the ball head to be tested from one side. Since the ball head to be tested is located between the standard ball head component 11 and the image acquisition camera 13, the image acquisition camera 13 takes pictures of the ball head to be tested and the standard ball head component 11. The overlapping part and the non-overlapping part between the ball head to be tested and the standard ball head component 11 can be obtained (the non-overlapping part is the worn part of the ball head to be tested). This can be understood as the two ball heads being superimposed, and there is a non-overlapping part between the worn part of the ball head to be tested and the edge of the standard ball head component 11.
[0027] The subsequent processing of the above images will be carried out using existing artificial intelligence for recognition and calculation, which will not be elaborated here.
[0028] Example 2:
[0029] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: a background shielding plate 5 is longitudinally arranged on the left end of the upper surface of the support platform 3.
[0030] Analysis of the above content: The background panel 5 can be made of light-colored solid material, the ball head to be tested is a conventional metallic color, and the standard ball head 11 can be painted white or other light colors to facilitate the display of non-overlapping parts, and the color is different from that of the background panel 5.
[0031] Example 3:
[0032] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: it further includes a base plate 1, the upper surface of which is connected to a bracket 2, the upper end of which is fixedly connected to the lower surface of a support platform 3, a motor 6 is mounted on the base plate 1, and the output shaft of the motor 6 is connected to the middle of the lower surface of the support platform 3. A bearing 4 is embedded in the support platform 3, and the output shaft of the motor 6 is inserted into the bearing 4.
[0033] Analysis of the above content: Motor 6 adopts a stepper motor with precise rotation control, and is controlled by an external PLC (existing technology, which will not be elaborated here). The stepper motor drives the ball head to be tested to rotate based on the turntable 7, and detects the ball head to be tested from different positions (the standard ball head 11 does not need to rotate, as the upper end of the standard ball head 11 is spherical, and there is no change when it rotates).
[0034] Example 4:
[0035] Please see Figure 1-3 The present invention provides a technical solution based on embodiment three: a column 12 is provided on the upper surface of the base plate 1, and the image acquisition camera 13 is installed on the top of the column 12.
[0036] Analysis of the above content: Column 12 is used to stably support the image acquisition camera 13.
