Detailed Implementation
[0020] 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.
[0021] like Figures 1 to 4 As shown, this utility model provides an adjustable testing fixture, including a workbench 1, a mounting frame 4 fixed on the surface of the workbench 1, a mounting column 6 mounted on the surface of the mounting frame 4, a positioning mechanism 3 provided at the bottom end of the mounting column 6, and a positioning mechanism 3 mounted on the upper side of the workbench 1.
[0022] The positioning mechanism 3 includes a fixed platform 33 fixedly connected to the upper surface of the worktable 1. A slider 31 is slidably connected to the surface of the fixed platform 33. A pressure plate 32 is fixedly connected to the upper side of the slider 31. A stop block 35 is fixedly connected to one side of the surface of the fixed platform 33. A T-shaped pressure block 36 is fixedly connected inside the pressure block 36. A movable groove for vertical movement of the pressure block 36 is opened inside the slider 31. A spring 39 is fixedly connected to the bottom end of the pressure block 36. Several sets of first teeth 37 are symmetrically fixedly connected to both sides of the surface of the pressure block 36. Several sets of second teeth 38 matching the first teeth 37 are symmetrically embedded in the top of the fixed platform 33. When fixing the workpiece, the positioning mechanism is achieved by... The workpiece to be tested is placed between the slider 31 and the stop block 35. Then, the slider 31 is pushed to move the pressure plate 32 toward the stop block 35 until the pressure plate 32 is in close contact with the workpiece. At the same time, the pressure block 36, under the action of the spring 39, drives the first tooth 37 and the second tooth 38 to clamp, locking the position of the pressure plate 32. The workpiece is clamped by the pressure plate 32 and the stop block 35, thus stably fixing the workpiece on the fixed table 33. By pressing the pressure block 36 to overcome the elastic force of the spring 39, the first tooth 37 and the second tooth 38 are separated, releasing the limit on the pressure plate 32. The position of the pressure plate 32 can be flexibly adjusted, which is convenient for positioning workpieces of different sizes.
[0023] The cross-sections of the first tooth 37 and the second tooth 38 are both right-angled triangles, and the directions of the first tooth 37 and the second tooth 38 are opposite. The right-angled triangle tooth design with opposite directions ensures the unidirectionality and stability of the positioning.
[0024] like Figures 1 to 4 As shown, guide plates 34 are symmetrically fixedly connected to both sides of the surface of the fixed platform 33, and the pressure plate 32 slides between the two sets of guide plates 34. When the pressure plate 32 moves, it will slide on the surface of the guide plate 34. The guide plate 34 limits the movement of the pressure plate 32, thereby improving the stability of the movement of the pressure plate 32.
[0025] An L-shaped rubber pad is fixedly connected to the surface of the pressure plate 32, and the surface of the rubber pad is provided with a triangular anti-slip pattern. The L-shaped rubber pad and the triangular anti-slip pattern on the surface of the pressure plate 32 increase the friction with the workpiece surface, further improving the reliability of positioning.
[0026] like Figures 1 to 4 As shown, the angle adjustment mechanism 2 includes an adjustment shaft 22 rotatably connected to the bottom of the mounting column 6. Mounting housings 5 are fixedly connected to both sides of the adjustment shaft 22. A detection probe 7 is mounted on one side of the mounting housing 5. A motor 24 is installed inside the mounting column 6. A gear 23 is connected to the output end of the motor 24. A side gear ring 21 is meshed with the surface of the gear 23 and is fixedly sleeved on the surface of the adjustment shaft 22. When it is necessary to adjust the angle of the detection probe 7, the motor 24 inside the mounting column 6 is started. The motor 24 drives the gear 23 to rotate. Since the gear 23 meshes with the side gear ring 21, the side gear ring 21 drives the adjustment shaft 22 to rotate. The rotation of the adjustment shaft 22 causes the detection probe 7 mounted on the mounting housings 5 on both sides to change its angle. By adjusting the rotation direction and angle of the motor 24, the detection probe 7 can be precisely adjusted to the required detection angle.
[0027] Working principle and process: When fixing the workpiece, the workpiece to be tested is placed between the slider 31 and the stop 35. Then, the slider 31 is pushed to move the pressure plate 32 towards the stop 35 until the pressure plate 32 is in close contact with the workpiece. At the same time, the pressure block 36, under the action of the spring 39, drives the first tooth 37 and the second tooth 38 to clamp, locking the position of the pressure plate 32. The workpiece is stably fixed on the fixed table 33 by clamping the workpiece with the pressure plate 32 and the stop 35. By pressing the pressure block 36 to move against the elastic force of the spring 39, the first tooth 37 and the second tooth 38 are clamped together. The second tooth 38 separates, releasing the limit on the pressure plate 32, allowing for flexible adjustment of the pressure plate 32's position, facilitating the positioning of workpieces of different sizes. When it is necessary to adjust the angle of the detection probe 7, the motor 24 inside the mounting column 6 is started. The motor 24 drives the gear 23 to rotate. Since the gear 23 meshes with the side gear ring 21, the side gear ring 21 drives the adjusting shaft 22 to rotate. The rotation of the adjusting shaft 22 causes the detection probe 7 mounted on the mounting housing 5 on both sides to change its angle. By adjusting the rotation direction and angle of the motor 24, the detection probe 7 can be precisely adjusted to the required detection angle.
