Description

Technical Field

[0001] This application belongs to the field of testing equipment technology, and in particular relates to a clamp testing platform. Background Technology

[0002] Currently, the factory inspection of clamps requires comprehensive testing of multiple items, including airtightness, clamping force, and sensing function. In existing technologies, these tests are scattered across different workstations or performed by different tools, resulting in each clamp undergoing repeated disassembly, reassembly, handling, and repositioning, making the process cumbersome and time-consuming. The entire testing process is highly dependent on manual operation, observation, and recording, which not only becomes an efficiency bottleneck but also easily introduces misjudgments, missed detections, and recording errors. In addition, manually processing the massive amount of test data is inefficient and prone to errors. When all clamps need to be re-inspected after rectification, the above inefficient processes are repeated, further reducing the overall testing efficiency.

[0003] Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this application is to provide a clamp detection platform to solve the technical problem of low clamp detection efficiency in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a clamp inspection platform, comprising:

[0006] Base plate;

[0007] The bracket, connected to the base plate, forms the mounting station for the target clamp.

[0008] The clamping assembly has a pressure block that is spaced apart from the bracket and is movable, the pressure block moving in a direction perpendicular to the base plate and being able to move closer to or further away from the bracket;

[0009] A pressure sensor is connected to the base plate at a distance from the bracket, and the detection end of the pressure sensor can be clamped by the target clamp.

[0010] A photoelectric sensor is disposed between the pressure sensor and the bracket in a direction parallel to the base plate and is used to detect the position of the moving end of the target clamp.

[0011] The beneficial effects of the clamp inspection platform provided in this application are as follows: Compared with the prior art, this application integrates the clamp placement station, vertical clamping assembly, photoelectric sensor for detecting whether the clamp opening and closing action is normal, and pressure sensor for directly detecting the clamping force on the same base plate, thus constructing an integrated inspection workstation. This structure allows the core mechanical action (opening and closing) and key performance indicator (clamping force) detection of the clamp to be continuously and automatically completed in place after the clamp is clamped once, saving the disassembly and transportation time spent on moving the clamp to different special equipment or workstations for these two basic tests, thereby significantly improving the efficiency of clamp inspection, which is far superior to the prior art.

[0012] Optionally, at least two sets of photoelectric sensors are spaced apart in a direction parallel to the base plate. In this application, by measuring the time difference between the signals from these two sets of sensors triggered sequentially by the clamp's actuating end, the system can directly and automatically calculate the clamp's opening and closing speed or time. This replaces the inefficient and error-prone method of manually timing and recording using tools such as stopwatches, and avoids the time delay caused by step-by-step or moving detection when using a single sensor, thus further improving the efficiency of clamp detection.

[0013] Optionally, the clamp testing platform further includes a push-out mechanism connected to the base plate; the push-out mechanism is drively connected to the pressure sensor and is used to move the pressure sensor closer to or away from the bracket in a direction parallel to the base plate. The push-out mechanism added in this application enables automatic feeding and retraction of the pressure sensor. During testing, this mechanism can quickly and accurately deliver the sensor to the preset test position, and immediately retract it after the test, making room for clamp movement. This completely replaces the tedious steps of manually placing and removing the force measuring tool, shortening the preparation and conversion time for clamp force testing, and further improving the efficiency of clamp testing.

[0014] Optionally, the bracket is recessed from the side closer to the pressure sensor to the side farther away from the pressure sensor to form a positioning groove for positioning the target clamp; the recessed direction of the positioning groove is parallel to the base plate. The recessed positioning groove structure in this application provides rapid initial positioning of the clamp. The operator only needs to place the clamp into the groove along the recessed direction to achieve automatic alignment in the main horizontal direction, greatly reducing the time spent manually adjusting the clamp's placement position to align with the detection reference, improving the speed of the loading process, and further enhancing the efficiency of clamp detection.

[0015] Optionally, the clamp detection platform further includes a clamping seat connected to the bracket and a chuck movably connected to the base plate and capable of approaching or moving away from the clamping seat; the chuck moves parallel to the base plate and perpendicular to the recessed direction of the positioning groove. The clamping seat and movable chuck added in this application constitute a horizontal lateral automatic clamping mechanism. This mechanism can automatically complete the final fixation of the clamp from the side after vertical clamping, achieving sequential automated locking in multiple degrees of freedom directions. This replaces the manual use of additional clamps or wrenches for lateral tightening, further reducing the total time required for clamping and fixing, and thus improving the efficiency of clamp detection.

[0016] Optionally, the clamp testing platform further includes a control device connected to the base plate; the ejection mechanism, the pressure block, and the clamp are respectively communicatively connected to the control device and can be controlled by the control device to move. In this application, the ejection mechanism, pressure block, and clamp are uniformly controlled through communication connections. This allows the entire process, including clamp positioning and fixing, and test execution, to run automatically in sequence according to a preset program, eliminating the interval time for manual operation and waiting between each step. At the same time, the control device can automatically collect and process data from each sensor, perform qualification judgment, and automatically store the result data and generate reports, and even drive external equipment such as marking machines. This integrates the traditionally scattered and manual recording, sorting, and marking processes into an instantaneous automated data stream, which greatly improves the efficiency of the entire process from detection to information processing.

[0017] Optionally, the clamping block is a flexible material structure. In this application, the clamping block is defined as a flexible material structure. This design allows the clamping block to adaptively fit the upper surface of clamps of different models or with slight manufacturing errors, ensuring clamping force while avoiding repeated adjustments or heavy pressure due to poor rigid contact. This ensures a high success rate for clamping on the first attempt, reduces rework time due to improper clamping, and further improves the efficiency of clamp inspection.

[0018] Optionally, the clamping assembly further includes a bracket connected to the base plate, a support connected to the clamping block, and a drive shaft and a guide shaft spaced apart on the support. The drive shaft is used to connect to an external drive mechanism and is parallel to the guide shaft. The guide shaft movably passes through the bracket and can move relative to the bracket along its own axial direction. In this application, the cooperation between the guide shaft and the bracket ensures that the clamping block moves smoothly in a strictly vertical direction under the action of the drive mechanism. This stable guidance avoids the need for repeated lifting and lowering adjustments due to shaking, offset, or jamming during the clamping process, ensuring that each clamping action is fast and completed in one go, which is beneficial to further improving the efficiency of clamp detection.

[0019] Optionally, the guide shafts are symmetrically distributed radially on opposite sides of the drive shaft. In this application, symmetrically distributing the guide shafts on both sides of the drive shaft allows for more balanced force distribution on the pressure block, thereby further enhancing the smoothness of the pressure block's downward movement and its resistance to eccentric loading. This effectively prevents slow movement or even jamming caused by unilateral friction or increased resistance, ensuring high speed and high reliability of the clamping action, reducing downtime due to malfunctions, and further improving the efficiency of clamp detection.

[0020] Optionally, the clamp inspection platform also includes a handle connected to the base plate. The handle structure added in this application facilitates the movement or fine-tuning of the inspection platform by operators or maintenance personnel. This allows the platform to be deployed more quickly to different production lines or adjusted to the optimal workstation, reducing the time required for additional handling tools or multi-person collaboration due to inconvenient equipment movement, improving the flexibility and efficiency of equipment layout and adjustment, and further enhancing the efficiency of clamp inspection.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The present application will now describe a clamp detection platform provided in an embodiment. The clamp detection platform includes a base plate 100, a bracket 101, a clamping assembly, a pressure sensor 103, and a photoelectric sensor 104.

[0032] in:

[0033] The base plate 100 is typically a single sheet of metal, serving as the mounting foundation for the entire platform. A bracket 101 is connected to the base plate 100 and is used to place and support the clamp 200 to be measured, forming a fixed mounting position. The clamping assembly typically includes a pressure block 102, actuated by a drive mechanism (such as a standard cylinder or electric actuator), positioned above the bracket 101 and movable in a direction perpendicular to the base plate 100 to clamp or release the clamp 200. A pressure sensor 103, typically a thin-film pressure sensor or a force sensor, is mounted on the base plate 100 at a corresponding position, with its sensing end (such as a sensing film or probe) facing the mounting position so that it can be gripped by the clamp jaws and the force value measured. A photoelectric sensor 104, typically a through-beam or reflective photoelectric switch, is installed in the area between the pressure sensor 103 and the bracket 101 to detect changes in the position of the clamp's moving end (such as the clamp arm) in the horizontal direction.

[0034] According to the structure provided in this embodiment, when the clamp detection platform is working, the operator places the target clamp 200 on the bracket 101, and the clamping block 102 of the clamping assembly moves down to clamp and fix it. Subsequently, the clamp performs an opening and closing action: the photoelectric sensor 104 automatically detects whether its moving end has reached the predetermined position, thereby determining whether the opening and closing action has been executed properly; when it is necessary to test the clamping force, the clamp closes and directly clamps the detection end of the pressure sensor 103, and the sensor outputs a real-time force value. Throughout the process, the clamp does not need to be moved or re-clamped. This solution integrates the three functions of clamp positioning and clamping, optical detection of the action status, and clamping force measurement into the same workstation supported by the base plate 100, realizing centralized and continuous testing of core performance, eliminating the intermediate links of repeatedly moving and disassembling clamps between different special equipment, thereby significantly shortening the total time of a single test and improving the testing efficiency.

[0035] It is understood that the photoelectric sensor 104 in this embodiment is not limited to a specific model or mounting point, as long as it can detect the predetermined position of the clamp's moving end. A slotted photoelectric sensor 104 or a proximity switch can also be used to achieve similar functions. The specific structure of the clamping assembly can also be modified. Its driving source can be a hydraulic cylinder, a servo motor, or other linear drive mechanism. The clamping block 102 can also be designed as replaceable or with a floating joint to adapt to the surface contours of different clamps. In addition, the specific type and installation method of the pressure sensor 103 can also be selected and adjusted according to the measurement range and requirements.

[0036] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3At least two sets of photoelectric sensors 104 are spaced apart in a direction parallel to the base plate 100. In this embodiment, both sets of photoelectric sensors 104 are used to detect different positions of the clamping end (such as the clamp arm) on the horizontal movement path. The conventional implementation is as follows: select through-beam or reflective photoelectric sensors 104 of the same or different specifications, fix them on the base plate 100 by their respective mounting brackets 110, and ensure that their beam detection areas are arranged at intervals along the movement trajectory of the clamping end, for example, one set is close to the expected "fully open" position of the clamp, and the other set is close to the expected "fully closed" position.

[0037] According to the structure provided in this embodiment, the addition of at least two sets of spaced photoelectric sensors 104 enhances time measurement. When the clamp's moving end moves, it sequentially triggers (or de-activates) the light beams of these two sets of sensors. By recording the time interval between two trigger signals, the system can directly and automatically calculate the speed or time taken for the clamp to move from one position to another. The technical advantage of this design is that it achieves quantitative and automated measurement of the synchronicity or speed of the clamp's opening and closing movements, completely replacing the inefficient traditional method of relying on manual timing with a stopwatch and visual judgment. Automated timing not only eliminates human error but also seamlessly integrates this test into an automatic cycle, eliminating the need for additional manual intervention and recording steps, thereby further shortening the detection cycle and improving overall detection efficiency.

[0038] It is understood that in this embodiment, the number of photoelectric sensors 104 can be more than two sets to monitor more location points or perform redundancy verification; their installation positions do not necessarily correspond strictly to the extreme positions of "fully open" or "fully closed", and can also be set at any two points in the stroke to measure interval speed; sensor types can be mixed, for example, one set uses through-beam type and another set uses reflective type. In addition, the system used for timing and calculation can be a module integrated with the main control PLC or a separate timing unit.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The clamp detection platform also includes an ejection mechanism 105 connected to the base plate 100. The ejection mechanism 105 is drive-connected to the pressure sensor 103 and is used to drive the pressure sensor 103 to move closer to or away from the bracket 101 in a direction parallel to the base plate 100. In this embodiment, the ejection mechanism 105 is typically a linear drive device, such as a cylinder, an electric push rod, or a linear module (screw slide). Its power output end (such as the piston rod front end of a cylinder or the slider of a slide) is drive-connected to the base portion of the pressure sensor 103 through a mounting plate or connector, thereby driving the pressure sensor 103 as a whole to make linear reciprocating motion in a direction parallel to the base plate 100, realizing the clamp placement position on the bracket 101.

[0040] According to the structure provided in this embodiment, when a clamping force test is required, the control device 109 activates the ejection mechanism 105. The ejection mechanism 105 smoothly and accurately pushes the pressure sensor 103, which was originally in the initial standby position, forward until its detection end (such as the thin-film sensing surface) reaches the preset test position directly in front of the clamp jaws. After the clamp closes and performs the clamping action, the pressure sensor 103 completes the measurement. Subsequently, the ejection mechanism 105 immediately moves to pull the pressure sensor 103 back from the test position to the initial position, making room for the subsequent opening and closing action of the clamp or unloading. The technical effect of this design is that it realizes the automatic access and exit of the clamping force testing station. It completely replaces the cumbersome manual steps of the traditional method, which requires operators to manually pick up, place, and align the force gauge, and then manually remove it after the test is completed. Not only does it eliminate time fluctuations caused by differences in human operation speed and accuracy, but more importantly, it seamlessly and automatically embeds the clamping force test into the overall inspection cycle, avoiding interruptions in the process due to waiting for manual operation. This significantly shortens the time spent on the clamping force test in a single inspection and improves the overall inspection efficiency.

[0041] It is understood that the specific implementation of the ejection mechanism 105 in this embodiment can have various variations. For example, its driving source is not limited to a cylinder, but can also be a synchronous belt mechanism driven by a stepper motor or a ball screw mechanism; the transmission connection method can be a direct rigid connection, or it can be connected through a floating joint or a quick-change joint, so as to facilitate the maintenance or replacement of the pressure sensor 103; the stroke and installation angle (horizontal or slightly tilted) of the ejection mechanism 105 can be adjusted according to the actual workstation layout. As long as the mechanism can realize the automatic switching of the pressure sensor 103 between the "test position" and the "avoidance position", it falls within the scope of this application.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The bracket 101 is recessed from the side near the pressure sensor 103 to the side away from the pressure sensor 103 to form a positioning groove 106 for positioning the target clamp 200; the recessed direction of the positioning groove 106 is parallel to the base plate 100. In this embodiment, the bracket 101 is typically machined from a metal block or plate, and its side near the pressure sensor 103 (i.e., the side facing the clamping end of the clamp) is recessed to the other side (i.e., the side away from the pressure sensor 103) to form a positioning groove 106 for accommodating and positioning the target clamp 200. The recessed direction of the positioning groove 106, i.e., the extension direction of the groove, is designed to be parallel to the base plate 100. In conventional implementations, the contour of the positioning groove 106 (such as width, depth, and bottom shape) is designed to match the characteristics (such as flanges, guide rails, or specific contours) of the clamp base to ensure that the clamp can be quickly and accurately guided in that direction after being placed.

[0043] According to the structure provided in this embodiment, when placing the clamp, the operator only needs to push or place its base into the groove along a specific direction parallel to the base plate 100 (i.e., the recessed direction of the positioning groove 106). Due to the constraint of the positioning groove 106, the position of the clamp in the horizontal plane along the extension direction of the groove (usually the length direction or main positioning direction of the clamp) is automatically and physically defined and aligned. The technical effect of this design is that it provides a mechanized guiding reference for achieving rapid and accurate clamp loading. Compared with the traditional method that requires the operator to manually adjust and repeatedly align the clamp position entirely by eye and experience, the positioning groove 106 greatly reduces or even eliminates repeated fine-tuning actions during the loading process. This significantly shortens the preparation time before each inspection, improves the speed and consistency of the loading process, and thus lays a good foundation for improving overall inspection efficiency.

[0044] It is understood that the cross-sectional shape of the positioning groove 106 in this embodiment is not limited to a rectangle, but can also be V-shaped, trapezoidal, or other asymmetrical shapes that match the bottom of the clamp. The positioning groove 106 can extend through both ends of the bracket 101 or be closed at one end. The recess is not limited to integral milling; it can also be formed by adding two parallel positioning blocks or guide strips to the bracket 101 to form an equivalent groove structure. In addition, adjustable positioning blocks or pads can be added inside the positioning groove 106 to accommodate clamps of different sizes.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The clamp detection platform also includes a clamp base 107 connected to the bracket 101 and a chuck 108 movably connected to the base plate 100 and capable of approaching or moving away from the clamp base 107; the movement direction of the chuck 108 is parallel to the base plate 100 and perpendicular to the recessed direction of the positioning groove 106. In this embodiment, the clamp base 107 is typically a fixed support block or positioning surface, and the chuck 108 is typically a movable pressure block 102 or top block. The chuck 108 is typically connected to a horizontally positioned drive mechanism (such as a small cylinder or electric push rod) to keep its movement direction parallel to the base plate 100, and the movement direction of the chuck 108 is perpendicular to the recessed direction of the aforementioned positioning groove 106 (i.e., the initial positioning direction of the clamp).

[0046] According to the structure provided in this embodiment, after the operator places the clamp into the positioning slot 106 to complete the initial positioning, the testing program is started. Simultaneously or subsequently, the control system drives the horizontal clamp 108 to move along its direction, engaging with the fixed clamp seat 107, and applying clamping force to the clamp from a direction perpendicular to the positioning slot 106 (usually the width direction or side of the clamp). The technical effect of this design is that it achieves automatic and reliable locking of the clamp in its second degree of freedom in the horizontal plane. Combined with the unidirectional positioning provided by the positioning slot 106, this lateral clamping mechanism ensures that the clamp is completely fixed in the workstation before testing, forming a stable "one-sided two-pin" (or similar principle) rapid positioning and clamping effect. This completely replaces the cumbersome operation of using additional clamps, wrenches, or manual tightening mechanisms for lateral fixing in the traditional method, automating the time-consuming lateral tightening action in the clamping process, further reducing the clamping preparation time for a single test, thereby improving the overall testing efficiency.

[0047] It is understood that in this embodiment, the specific shapes of the clamp 107 and the chuck 108 can be designed as planar or strip-shaped contact blocks according to the contour of the clamp side; the power source for driving the chuck 108 is not limited to a cylinder, but can also be a hydraulic cylinder or a linear motor; a force sensor can be added between the chuck 108 and the driving component to achieve closed-loop control of the clamping force; in some layouts, the clamp 107 can also be adjustable or replaceable. In addition, this lateral clamping mechanism can be one or more sets to adapt to clamps with different structures.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The clamp detection platform also includes a control device 109 connected to the base plate 100; the ejection mechanism 105, the pressure block 102, and the chuck 108 are respectively communicatively connected to the control device 109 and can be controlled by the control device 109 to move. In this embodiment, the control device 109 typically refers to an industrial controller, such as a programmable logic controller (PLC) or an industrial computer (IPC). It establishes communication connections with the driver of the ejection mechanism 105, the actuator that drives the pressure block 102, and the actuator that drives the chuck 108 via electrical quick-connect interfaces (such as Harding connectors), fieldbus, or industrial Ethernet, thereby enabling it to send control commands and receive status feedback from these actuators.

[0049] According to the structure provided in this embodiment, the control device 109, as the core brain of the entire testing platform, works by executing a preset automated program. It automatically controls the forward and backward movement of the ejection mechanism 105, the lifting and lowering of the pressure block 102, and the clamping and releasing of the chuck 108 in a logical sequence, while simultaneously acquiring real-time signals from all testing elements such as the pressure sensor 103 and the photoelectric sensor 104. Based on these signals, it automatically performs data comparison and logical judgment, completes the qualification determination of various tests, and automatically stores all process data and results, generating a structured test report. It can also drive external equipment such as a marking machine to perform operations based on the results, thereby achieving fully automated closed-loop control from clamping, testing, judgment to data archiving. This not only completely eliminates the waiting time caused by manual operation, confirmation, and recording between each test step, integrating discrete manual operation processes into continuous, high-speed automatic equipment cycles; more importantly, it transforms post-processing links such as data recording, report generation, and even physical identification, which traditionally rely heavily on manual labor and are prone to errors, into instantaneous, automatic digital streams, greatly improving the overall process efficiency and reliability from test execution to information processing completion.

[0050] It is understood that the specific type of the control device 109 in this embodiment can be a higher-level industrial PC, embedded controller, or distributed I / O system; in addition, the functional modules implemented by the control device 109 can also be expanded or adjusted, such as data processing algorithms, report formats, and integration interfaces with MES / databases (such as NAS), which can all be customized according to different needs.

[0051] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The pressure block 102 is a flexible material structure. In this embodiment, the fact that the pressure block 102 is a flexible material means that the main body of the pressure block 102 or the working part that directly contacts the clamp is made of a flexible material with a certain elasticity and capable of deformation, such as engineering rubber, polyurethane (PU), silicone, or other polymeric elastomers. In conventional implementations, the flexible pressure block 102 can be directly molded into the required shape (such as a block or a contoured pad) and mounted on the end of the drive component by bonding, mechanical embedding, or through a rigid base.

[0052] According to the structure provided in this embodiment, when the pressure block 102 moves downward under the action of the driving device and contacts the upper surface of the clamp, the flexible material can adapt to the micro-unevenness or macro-contour differences of the clamp surface to a certain extent. Even if the clamp has slight changes in the shape and height of the upper surface due to different models or manufacturing tolerances, the flexible pressure block 102 can achieve more uniform and stable surface contact through its own local compression deformation, thereby providing reliable clamping force. Compared with the rigid pressure block 102, the flexible pressure block 102 avoids the repeated adjustment of the position or pressure of the pressure block 102 and repeated clamping operations caused by poor contact, local point contact or the need for precise alignment. This ensures the success rate and reliability of a single clamping action, reduces the time wasted due to unstable clamping or repeated adjustments, and thus helps to stabilize and improve the clamping efficiency of the overall inspection process.

[0053] It is understood that the flexible material of the clamping block 102 can be uniform throughout, or it can be designed as a composite structure with a flexible surface and internal support; its shape is not limited to a simple cube, but can be a contoured structure matching the top profile of common clamps, or a larger flat surface designed to increase the contact area. The flexible clamping block 102 can also be replaceable to adapt to different series of clamps. In addition, the way to achieve "flexibility" is not limited to the material itself, but can also be achieved by adding an independent flexible pad or liner between the rigid clamping block 102 and the clamp contact surface to achieve equivalent function.

[0054] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The clamping assembly also includes a bracket 110 connected to the base plate 100, a support 111 connected to the pressure block 102, and a drive shaft 112 and a guide shaft 113 spaced apart on the support 111. The drive shaft 112 is used to connect to an external drive mechanism and is parallel to the guide shaft 113. The guide shaft 113 movably passes through the bracket 110 and can move relative to the bracket 110 along its own axial direction. In this embodiment, the bracket 110 is often a gantry frame or column structure. The drive shaft 112 can be the piston rod of a cylinder or the output shaft of an electric push rod. The guide shaft 113 is usually a light shaft or a linear bearing shaft, and its rod body is movably inserted into the corresponding guide hole or linear bearing on the bracket 110, so that the guide shaft 113 can slide freely relative to the bracket 110 along its own axial direction (i.e., perpendicular to the base plate 100).

[0055] According to the structure provided in this embodiment, when the external drive mechanism pushes the drive shaft 112, the power is transmitted to both the drive shaft 112 and the guide shaft 113 simultaneously through the support 111. The guide shaft 113, due to its precise fit with the guide hole of the bracket 110, plays a crucial guiding and supporting role, constraining the support 111 and the pressure block 102 to move smoothly in a strictly vertical direction, effectively preventing the pressure block 102 from swaying laterally, tilting, or rotating during lifting. The technical effect of this design is that it greatly improves the accuracy and reliability of the clamping action. Smooth, wobbly linear motion ensures that the pressure block 102 can accurately clamp the clamp with a consistent posture each time, avoiding problems such as pressure deviation, jamming, or the need for repeated lifting and lowering adjustments due to non-straight movement trajectories. This not only shortens the time required for a single clamping action, but more importantly, by ensuring a high success rate, it reduces cycle interruptions or rework caused by clamping failures, thereby stabilizing and improving the rhythm and efficiency of the overall testing process.

[0056] It is understood that in this embodiment, the number of guide shafts 113 can be one, two, or more to provide different levels of guiding stability; the components that cooperate with them on the bracket 110 can be simple bushings, linear bearings, or sliding bushings. The connection between the drive shaft 112 and the drive mechanism can be a rigid connection or a floating joint connection to compensate for minor alignment errors. Furthermore, the specific structural form of the bracket 110 can be a closed frame or an open cantilever structure, as long as it can provide stable support and guidance for the guide shaft 113.

[0057] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The guide shafts 113 are symmetrically distributed on opposite sides of the drive shaft 112 along the radial direction of the drive shaft 112.

[0058] According to the structure provided in this embodiment, when the drive shaft 112 drives the support 111 and the pressure block 102 downward, the driving force acting on the support 111 is transmitted approximately along the centerline of the drive shaft 112. The two symmetrically arranged guide shafts 113 provide completely equal guiding constraints and sliding supports from both sides, ensuring that the guiding reaction force on the support 111 is also symmetrically distributed. The technical effect of this design is that it greatly optimizes the stress state of the clamping assembly and eliminates the eccentric torque that may be generated due to the asymmetrical arrangement of the guide components. This makes the pressure block 102 move more smoothly, effectively avoiding the risk of additional friction, increased wear, or even jamming caused by uneven force on one side of the guide shaft 113. Higher motion smoothness and reliability directly ensure that the clamping action can be performed continuously at high speed and without failure, reducing unplanned downtime caused by maintenance or handling jamming problems, thereby ensuring the long-term stability and efficiency of the testing platform.

[0059] It is understood that "symmetrical distribution" in this embodiment does not mean that the guide shafts 113 must be strictly located on the horizontal line directly to the left and right of the drive shaft 112. They can also be symmetrically distributed on the upper left-lower right or other centrally symmetrical positions of the drive shaft 112. The number of guide shafts 113 can be two or four (arranged symmetrically in pairs) to achieve higher stability. In addition, the symmetrical "radial" distance can be adjusted according to the structural space, and does not have to be equidistant, but it needs to maintain torque balance.

[0060] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The clamp inspection platform also includes a handle 114 connected to the base plate 100. In this embodiment, the handle 114 is typically a component for human hand gripping, commonly in the form of a U-shaped or ring-shaped handle made of bent metal rod, or a molded handle with a gripping part. It is usually fixed to the side or end of the base plate 100 at a position convenient for applying force by means of screws, welding, or riveting.

[0061] According to the structure provided in this embodiment, the handle 114 itself does not participate in the direct detection action, but its function is reflected in the deployment, adjustment, and maintenance of the equipment. When the detection platform needs to be moved or its orientation adjusted within the work area, or repositioned after maintenance, operators or maintenance personnel can grasp the handle 114 to lift or drag the platform more effortlessly and stably. The technical effect of this design is that it significantly improves the mobility and adjustment convenience of the equipment in non-detection states. Compared with directly lifting the heavy base plate 100 or using external handling tools, the dedicated handle 114 makes rapid and flexible deployment of the equipment possible. This reduces the difficulty and time spent on platform movement and positioning due to production line layout adjustments, workstation optimization, or equipment maintenance, thereby indirectly ensuring that the detection workstation can be put into production or resume operation more quickly, improving the efficiency of the arrangement and execution of detection-related work from an overall operational perspective.

[0062] It is understood that the implementation of the handle 114 in this embodiment can have various variations. For example, the number of handles 114 can be one or more, and they can be installed on one side, both sides, or the end of the base plate 100; their specific shape can be arc-shaped, D-shaped, folding, or a straight rod with soft rubber coating; the installation method can be permanent, or it can be detachable or rotatable to save space. The material of the handle 114 can also be metal, engineering plastics, etc.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
