Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a workpiece height testing mechanism. Background Technology

[0002] In modern industrial production and quality inspection, workpiece height detection is a crucial step in ensuring product accuracy and consistency. With the increasing sophistication of manufacturing processes, the demand for precise height detection of various parts of workpieces is becoming increasingly urgent. 3D scanners, with their ability to generate three-dimensional views, have become the core equipment for achieving this detection.

[0003] In existing technologies, 3D scanners rely on a guide rail platform, moving back and forth along the rail to cover different workpieces and various inspection areas to complete height detection tasks. Stable mounting of the 3D scanner on the guide rail requires the assistance of a fixture. However, traditional fixtures used for mounting 3D scanners are limited by structural design and material selection, resulting in significant weight. From a mechanical perspective, the fixture's weight directly acts on the guide rail, greatly increasing the friction between the 3D scanner and the guide rail. When the 3D scanner moves on the guide rail, excessive friction not only reduces the smoothness of its movement and increases drive energy consumption, but also easily leads to uneven movement speed, jamming, or even stagnation, affecting the continuity and stability of scanning and inspection. In actual inspection scenarios, if the 3D scanner's movement is disturbed, the generated 3D view is prone to data loss and decreased accuracy, failing to accurately reflect the height of various parts of the workpiece, thus interfering with the judgment of inspection results and adversely affecting product quality control. Meanwhile, prolonged operation under high friction conditions will accelerate the wear and tear of components in the 3D scanner and guide rail, shorten the equipment's lifespan, increase maintenance costs and the probability of equipment downtime, and reduce overall testing efficiency.

[0004] Furthermore, as industrial production demands ever higher efficiency and accuracy in inspection, the drawbacks of traditional fixtures are no longer adequate for automated, high-speed inspection processes. Therefore, developing a mechanism that effectively addresses the weight issue of traditional fixtures, optimizes the movement performance of 3D scanners on guide rails, and ensures high-quality and efficient workpiece inspection has become an urgent need for improving current industrial inspection equipment. Utility Model Content

[0005] To address the aforementioned issues, a workpiece height detection mechanism is provided. Through the synergy of a "support assembly + spacing adjustment component + support adjustment assembly", the problem of movement jamming caused by excessive fixture weight is solved.

[0006] To address the problems of existing technologies, this utility model provides a workpiece height detection mechanism, including a moving guide rail, a 3D scanner, and a clamping mechanism linked to the moving guide rail. The clamping mechanism can clamp the 3D scanner. The clamping mechanism includes a support assembly, a spacing adjustment component, and a support adjustment component.

The 3D scanner is disposed between the two support assemblies. At least two sets of the support adjustment components are respectively disposed on the two support assemblies, and the support adjustment components are used to contact and adapt to the corresponding side supporting the 3D scanner.

The rotating rod passes through the movable sleeve. Rotating the rotating rod can press one end of the rotating rod against the side wall of the 3D scanner.

[0012] Preferably, rubber pads are provided on the sides of the two support frames that are close to each other.

[0013] Preferably, a turntable is provided at the end of the rotating rod away from the 3D scanner.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1-6As shown, this utility model provides a workpiece height detection mechanism, including a moving guide rail 1, a 3D scanner 2, and a clamping mechanism 3 linked to the moving guide rail 1. The clamping mechanism 3 can clamp the 3D scanner 2. The clamping mechanism 3 includes a bracket assembly 30, a spacing adjustment component 31, and a support adjustment component 32. At least two sets of bracket assemblies 30 are arranged opposite each other, and one set of bracket assemblies 30 is adapted and connected to the moving platform of the moving guide rail 1. The spacing adjustment component 31 is used to connect the two bracket assemblies 30. Operating the spacing adjustment component 31 can adjust the spacing between the two bracket assemblies 30. The 3D scanner 2 is arranged between the two bracket assemblies 30. At least two sets of support adjustment components 32 are respectively arranged on the two bracket assemblies 30. The support adjustment components 32 are used to contact and adapt to the corresponding side supporting the 3D scanner 2.

[0025] Based on the dimensions of the 3D scanner 2, the operating distance adjustment component 31 adjusts the distance between the two support assemblies 30, allowing the 3D scanner 2 to be stably placed between the two sets of supports. Then, by adjusting the support adjustment component 32, it is ensured to make tight contact with both sides of the 3D scanner 2. At this point, the support adjustment component 32 not only provides clamping force but also ensures that the 3D scanner 2 will not shake or shift during movement through flexible contact or posture calibration. The clamping mechanism 3 moves along the guide rail 1 with the moving platform, driving the 3D scanner 2 to perform omnidirectional scanning of the workpiece. Due to the stable connection between the support assembly 30 and the moving platform, and the reliable fixation of the 3D scanner 2 by the support adjustment component 32, the equipment will not experience displacement or vibration during high-speed movement or start-up and shutdown, ensuring the continuity and accuracy of the 3D view data. This design, through the synergy of "support assembly 30 + spacing adjustment component 31 + support adjustment component 32", not only solves the problem of movement jamming caused by excessive fixture weight (lightweight design can be achieved by optimizing the support material), but also breaks through the limitations of fixed structure in adapting to different specifications of 3D scanner 2. At the same time, with the adjustable characteristics of support adjustment component 32, it can adapt to 3D scanner 2 with uneven shell, ultimately achieving a comprehensive effect of "efficient movement + precise clamping + multi-specification compatibility", adapting to the diverse workpiece height detection needs in automated production lines.

[0026] It should be noted that there is a gap between the end of the 3D scanner 2 connected to the data cable, wires, etc. and the moving guide rail 1. An auxiliary support can be set on the moving platform of the moving guide rail 1. The auxiliary support moves with the 3D scanner 2, and the wires connected to the 3D scanner 2 can be guided to the drag chain set near the moving guide rail 1 through the auxiliary support, thereby avoiding interference from the data cable, etc. on the movement of the 3D scanner 2.

[0027] The spacing adjustment component 31 is a threaded rod. One end of the threaded rod is set on one of the bracket assemblies 30, and the other end passes through another bracket assembly 30. Rotating the threaded rod can drive one of the bracket assemblies 30 to move closer to or away from the bracket assembly 30 connected to the moving guide rail 1.

[0028] The support assembly 30 includes a support frame 300 and movable buttons 301. Through slots 3000 are provided along two adjacent edges of the support frame 300, and two sets of movable buttons 301 are respectively disposed in the two through slots 3000. The support adjustment assembly 32 is linked to the two movable buttons 301. The support frame 300 has an "L-shaped" structure, with the two sets of through slots 3000 being horizontal and vertical respectively. This "L-shaped" structure of the support frame 300 provides multi-angle encircling support for the 3D scanner 2 using two mutually perpendicular frame edges, enhancing the overall structural stability. The support adjustment assembly 32 is linked to the two movable buttons 301; changes in the position of the movable buttons 301 will cause the support adjustment assembly 32 to move synchronously, thereby achieving position adjustment of the support adjustment assembly 32 in the horizontal and vertical directions to accommodate 3D scanners 2 of different sizes and shapes.

[0029] The support adjustment assembly 32 includes an adjustment frame 320 and adjustment keys 321. Two movable knobs 301 are disposed in the adjustment frame 320, and several adjustment keys 321 are movably disposed in the adjustment frame 320. At least one end of the adjustment frame 320 can extend out a through groove 3000, and the adjustment keys 321 can contact the side wall of the 3D scanner 2. The adjustment keys 321 can move within the adjustment frame 320, such as extending and retracting. When it is necessary to clamp the 3D scanner 2, the adjustment keys 321 can contact the side wall of the 3D scanner 2. By adjusting the extension length of different adjustment keys 321, it can adapt to the unevenness of the side wall of the 3D scanner 2, achieve a tight fit with the 3D scanner 2, and further enhance the stability and adaptability of clamping.

[0030] The adjustment key 321 includes a movable sleeve 3210 and a rotating rod 3211. The movable sleeve 3210 is confined to move within the adjustment frame 320. The outer wall of the rotating rod 3211 is threaded, and the rotating rod 3211 passes through the movable sleeve 3210. Rotating the rotating rod 3211 can press one end of the rotating rod 3211 tightly against the side wall of the 3D scanner 2. By rotating the rotating rod 3211, it can be adapted to and clamped to 3D scanners 2 with different shell structures.

[0031] Rubber pads are provided on the sides of the two support frames 300 that are close to each other. The rubber pads on the sides of the support frames 300 that are close to each other prevent hard contact between the 3D scanner 2 and the surface of the 3D scanner 2 when the 3D scanner 2 comes into contact with the rubber pads, thereby avoiding damage to the shell of the 3D scanner 2. For the 3D scanner 2 with flat sidewalls, the rubber pads should be on the same horizontal plane as one end of the rotating rod 3211.

[0032] A turntable 3212 is provided at the end of the rotating rod 3211 away from the 3D scanner 2. The turntable 3212 makes it easier to adjust the adjustment key 321 and to rotate the rotating rod 3211 to press it firmly against the outer wall of the 3D scanner 2.

[0033] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
