Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to an adjustable and limitable support testing platform. Background Technology

[0002] As we all know, in the field of industrial production, the inspection of parts is a key link to ensure product quality and the reliability of subsequent assembly. It is necessary to accurately verify the angular adaptability, structural stability and other indicators of parts. However, traditional parts inspection equipment has many technical pain points in practical applications and cannot meet the needs of efficient and accurate inspection.

[0003] In traditional multi-angle component inspection, the core problem lies in the lack of an integrated angle adjustment and stabilization locking mechanism in the inspection equipment. Existing equipment's clamping structure and angle adjustment function are independent, making it impossible to flexibly switch between different inspection angles and accurately fix the component after a single clamping. To meet multi-angle inspection requirements, operators must manually repeat the clamping process—that is, after inspecting one angle, the fixed component is first disassembled, its placement angle and position are manually adjusted, and then it is re-clamped and fixed before proceeding to the next angle. Furthermore, the derivative problems caused by repeated clamping exacerbate the industry's pain points: on the one hand, repeated manual disassembly and clamping can easily lead to component reference position shifts, resulting in deviations in subsequent inspection data due to the lack of a unified reference, affecting the accuracy of quality judgment; on the other hand, prolonged repetitive operations increase the operator's labor intensity, easily leading to clamping errors due to fatigue, further extending the inspection cycle or causing surface damage to components. This makes it difficult to adapt to complex scenarios such as dynamic inspection and continuous multi-angle inspection, limiting the equipment's application scope and overall value, thus hindering production efficiency improvement and economic benefit growth. Utility Model Content

[0004] Technical problems to be solved In view of the shortcomings of the existing technology, this utility model provides an adjustable and limitable support testing platform.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an adjustable and limiting bracket testing platform, comprising a testing platform, a first bracket, a second bracket, an adjustment mechanism, and a limiting mechanism. The first bracket and the second bracket are respectively installed on the left and right ends of the top wall of the testing platform. A cylinder is installed on the side wall of the first bracket. The output end of the cylinder passes through the side wall of the first bracket and is fitted with a first clamping plate via a bearing. The adjustment mechanism includes a driving gear, a driven gear, a rotating shaft, a first motor, and a second clamping plate. The rotating shaft is rotatably installed on the end of the second bracket near the first bracket. The second clamping plate is installed on the end of the rotating shaft. The driven gear is sleeved through the side wall of the second bracket at the end of the rotating shaft away from the second clamping plate. The driving gear is meshed below the driven gear. The first motor is installed on the end of the driving gear away from the second bracket. The limiting mechanism is installed above the driven gear.

[0006] Furthermore, the present invention is improved in that the limiting mechanism includes a rectangular groove, a threaded rod, a slider, a limiting plate, a toothed groove, and a second motor. The rectangular groove is formed on the side wall of the second bracket away from the first bracket. The threaded rod is rotatably installed in the rectangular groove. The top end of the threaded rod passes through the top wall of the rectangular groove to install the second motor. The slider is threadedly installed on the outer wall of the threaded rod. The limiting plate is installed on the side wall of the slider through a connecting rod. The bottom wall of the limiting plate has multiple toothed grooves, which mesh with the driven gear.

[0007] Furthermore, the present invention is improved in that two sets of guide rods are symmetrically installed in the rectangular groove with respect to the central axis of the threaded rod, and guide holes are opened at both ends of the slider, and the guide rods and the guide holes are slidably connected.

[0008] Furthermore, an improvement of this utility model is that both the first motor and the second motor are servo motors.

[0009] Furthermore, the present invention is improved by installing adjustable support legs at the four corners of the bottom of the testing platform.

[0010] Furthermore, the present invention is improved in that rubber pads are installed on the corresponding sidewalls of the first clamping plate and the second clamping plate.

[0011] Furthermore, the present invention is improved in that the surface of the rubber pad is provided with anti-slip texture, and the anti-slip texture is distributed in a cross-grid pattern.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides an adjustable and limitable support testing platform, which has the following advantages: This adjustable and limit-positioning bracket testing platform, through its set adjustment mechanism, uses gear transmission as its core transmission chain. The stable power output from the motor is precisely transmitted to the rotating shaft through gear meshing. The meshing transmission between the driving gear and the driven gear has no risk of slippage, and can accurately convert the speed of the first motor into the rotation angle of the rotating shaft. At the same time, the cylinder output end is connected to the first clamping plate through a bearing, which not only does not affect the stable clamping of the parts by the first clamping plate, but also cooperates with the second clamping plate to rotate synchronously with the rotating shaft, ensuring that the parts always maintain coaxial rotation during the adjustment process.

[0013] This adjustable and limit-positioning support testing platform, through its set-in limit mechanism, effectively prevents the rotation angle of components from exceeding the preset range. Simultaneously, the stable clamping and transmission structure ensures that components remain stable during adjustment, preventing shaking or displacement and guaranteeing the accuracy of the testing data. The adjustment and limit mechanisms do not work independently but form a synergistic "precise adjustment - firm locking" system. This synergy not only further improves the accuracy and stability of angle control but also allows the equipment to adapt to more complex testing scenarios such as dynamic testing and multi-angle continuous testing, significantly expanding the equipment's application range, enhancing its overall value, and bringing higher economic benefits to enterprises.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-4An adjustable and limiting support testing platform includes a testing platform 1, a first support 2, a second support 3, an adjustment mechanism, and a limiting mechanism. The first support 2 and the second support 3 are respectively installed on the left and right ends of the top wall of the testing platform 1. A cylinder 4 is installed on the side wall of the first support 2, and the output end of the cylinder 4 passes through the side wall of the first support 2 and is mounted on a first clamping plate 5 via a bearing. The adjustment mechanism includes a driving gear 6, a driven gear 7, a rotating shaft 8, a first motor 9, and a second clamping plate 10. The rotating shaft 8 is rotatably mounted on the end of the second support 3 closest to the first support 2, and the second clamping plate 10 is installed on the end of the rotating shaft 8. The end of the rotating shaft 8 furthest from the second clamping plate 10... The driven gear 7 is sleeved through the side wall of the second bracket 3. The driving gear 6 is meshed below the driven gear 7. The first motor 9 is installed at the end of the driving gear 6 away from the second bracket 3. The limiting mechanism is installed above the driven gear 7. In this embodiment, the component to be tested is placed above the central area of ​​the testing table 1, ensuring that the clamping parts of the component correspond to the first clamping plate 5 and the second clamping plate 10 respectively. At this time, the first clamping plate 5 is in a position away from the second clamping plate 10 in the initial state of the cylinder 4, leaving sufficient space for the component to be placed. The cylinder 4 installed on the side wall of the first bracket 2 is started by the control device. The output end of the cylinder 4 moves horizontally towards the second bracket 2. One side of the bracket 3 extends out, and under the pushing action of the output end, the first clamping plate 5 smoothly approaches the component. As the output end of the cylinder 4 continues to advance, the first clamping plate 5 first contacts one side of the component, and then continues to apply a stable clamping force. When the first clamping plate 5 and the second clamping plate 10 together clamp the component, and the clamping force reaches the stable state required for detection, the cylinder 4 is closed. At this time, the component is firmly fixed between the two clamping plates to prevent displacement during the detection process. According to the detection requirements, the first motor 9 is started by the control device. The output shaft of the first motor 9 drives the drive gear 6 to rotate. Since the drive gear 6 and the driven gear 7 mesh with each other, the rotation of the drive gear 6 will synchronously drive the driven gear 7 to rotate. Driven gear 7 is mounted on the rotating shaft 8 that passes through the second bracket 3. The rotation of driven gear 7 will directly drive the rotating shaft 8 to rotate. The end of the rotating shaft 8 near the component is equipped with a second clamping plate 10, and the component has been fixed by the first clamping plate 5 and the second clamping plate 10. Since the output end of cylinder 4 is connected to the first clamping plate 5 through a bearing, the rotation of the rotating shaft 8 will synchronously drive the component clamped by the first clamping plate 5 and the second clamping plate 10 to perform precise rotation angle adjustment. When the component rotates to the preset detection angle, the first motor 9 is turned off, the component stops rotating and stops precisely at the target angle. The limit mechanism will trigger a signal to limit driven gear 7 to ensure the stability of subsequent component detection.

[0018] Preferably, in this embodiment, the limiting mechanism includes a rectangular groove 11, a threaded rod 12, a slider 13, a limiting plate 14, toothed grooves 15, and a second motor 16. The rectangular groove 11 is formed on the side wall of the second bracket 3 away from the first bracket 2. The threaded rod 12 is rotatably installed in the rectangular groove 11. The top end of the threaded rod 12 passes through the top wall of the rectangular groove 11 and is used to install the second motor 16. The slider 13 is threaded onto the outer wall of the threaded rod 12. The limiting plate 14 is installed on the side wall of the slider 13 via a connecting rod. The bottom wall of the limiting plate 14 has multiple toothed grooves 15. The toothed grooves 15 mesh with the driven gear 7. After the first motor 9 drives the driving gear 6, the driven gear 7, and the rotating shaft 8 to rotate, and the component is adjusted to the target detection angle (e.g., 30°, 45°), the first motor 9 is kept stationary with the power off. At this time, although the component has been initially positioned, the driven gear 7 is still at risk of rotating due to external forces (e.g., subsequent detection loading forces). Therefore, the limiting mechanism needs to be activated to lock it, and the second motor 16 is connected. The power supply of the second motor 16 drives the threaded rod 12, which is fixedly connected to it, to rotate clockwise within the rectangular groove 11. The rectangular groove 11 provides stable rotational support for the threaded rod 12, preventing it from wobbling. Since the outer wall of the threaded rod 12 is connected to the inner wall of the slider 13 via a threaded connection, and the slider 13 is embedded in the rectangular groove 11 and limited by the side wall of the groove 11, it cannot rotate synchronously with the threaded rod 12. The rotation of the threaded rod 12 is converted into the longitudinal linear motion of the slider 13 along the rectangular groove 11. Driven by the threaded rod 12, it moves downward along the rectangular groove 11. The side wall of the slider 13 is fixedly connected to the limiting plate 14 through the connecting rod, so it will synchronously drive the limiting plate 14 to move downward until the tooth groove 15 is completely engaged between the teeth of the driven gear 7. At this time, the second motor 16 is turned off, the threaded rod 12 stops rotating, the slider 13 and the limiting plate 14 are fixed in position, and the driven gear 7 is limited by the tooth groove 15 and can no longer rotate clockwise or counterclockwise. Then, the angle between the second clamping plate 10 and the component is fixed by the rotating shaft 8 to complete the locking.

[0019] Preferably, in this embodiment, two sets of guide rods 17 are symmetrically installed in the rectangular groove 11 along the central axis of the threaded rod 12. Guide holes 18 are opened at both ends of the slider 13. The guide rods 17 and the guide holes 18 are slidably connected. When the threaded rod 12 rotates to drive the slider 13 to move downward, the slider 13 is restricted by the sliding fit between the guide hole 18 and the guide rod 17, and cannot shift left or right or rotate. The slider 13 always moves vertically upward or downward along the axial direction of the guide rod 17. The fit between the guide rod 17 and the guide hole 18 restricts the rotational freedom of the slider 13, eliminates the friction between the slider 13 and the groove wall, protects the integrity of the rectangular groove 11, and extends the overall service life of the limiting mechanism.

[0020] Preferably, in this embodiment, both the first motor 9 and the second motor 16 are servo motors. The servo motor can precisely control the rotation speed and the number of rotations, thereby precisely controlling the rotation amplitude of the threaded rod 12, so that the slider 13 drives the limiting plate 14 to achieve millimeter-level or even micrometer-level displacement adjustment. During the locking phase of the limiting mechanism, the precise control of the servo motor can make the tooth groove 15 on the bottom wall of the limiting plate 14 "meet with zero clearance" with the teeth of the driven gear 7 (avoiding the excessively deep or shallow meshing caused by the unstable speed of ordinary motors). During the unlocking phase, the upward movement distance of the limiting plate 14 can also be precisely controlled to ensure that the tooth groove 15 is completely disengaged from the driven gear 7 and does not collide with other components, thereby improving the accuracy and reliability of the limiting control.

[0021] Preferably, in this embodiment, adjustable support legs 19 are installed at the four corners of the bottom of the testing platform 1. In the adjustable and limited support testing platform, the testing platform 1 serves as the core bearing foundation for placing parts and installing various functional modules. The design of installing adjustable support legs 19 at the four corners of its bottom solves the problem of uneven ground in the testing environment.

[0022] Preferably, in this embodiment, rubber pads 20 are installed on the corresponding sidewalls of the first clamping plate 5 and the second clamping plate 10. The rubber pads 20 have good elasticity and can undergo elastic deformation during clamping, dispersing the concentrated pressure of the clamping plates into uniform surface pressure, greatly reducing the force per unit area and avoiding mechanical damage due to hard contact, ensuring that the appearance and structural integrity can still be maintained after testing.

[0023] Preferably, in this embodiment, the surface of the rubber pad 20 is provided with anti-slip texture, and the anti-slip texture is distributed in a cross-grid pattern. The cross-grid pattern can make the surface of the rubber pad 20 form a concave-convex structure. When in contact with the surface of the component, the raised part of the texture will be embedded into the tiny depression on the surface of the component.
