Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a device for rapidly inspecting the height difference of the surface structure of a product. Background Technology

[0002] In industrial production, many products have structural features with height differences between two or more end faces on the same plane, such as components like pressure-reducing cam rocker arms. These products require precise height difference inspection during manufacturing to ensure product quality and assembly accuracy. Traditional inspection methods primarily rely on dial indicators for manual measurement, which has several drawbacks: First, when the product's bottom surface has multiple steps, tilting can easily occur during measurement due to a shift in the product's center of gravity, severely affecting the accuracy of the measurement results. Second, for products with multiple inspection surfaces, repeated adjustments to the measurement position are necessary, resulting in low inspection efficiency. Third, human error is inevitably introduced during manual operation, leading to poor repeatability of measurement results. Furthermore, existing inspection equipment often lacks effective product positioning and fixing mechanisms, making it difficult to guarantee product stability during measurement and further increasing inspection errors. These problems are particularly prominent in mass production, affecting not only product quality control but also hindering the improvement of production efficiency. Utility Model Content

[0021] Reference Figures 1 to 3 This utility model provides a device for quickly inspecting the height difference of product surface structure, mainly applied to applications such as... Figure 4 The product to be inspected is shown as 1. Specifically, the inspection equipment includes a workbench 100, an inspection mechanism, and a pressing mechanism 600. The workbench 100 is equipped with a control box and a display device 300. The inspection mechanism includes a fixedly connected first support base 400, a movably connected abutment rod 500, and a detection sensor. The pressing mechanism 600 includes a pressing drive 610 and a pressing block 620. The pressing drive 610 pushes the pressing block 620 to make the product form a limited abutment with the first support base 400. The detection sensor detects the displacement of the abutment rod 500 and transmits it to the control box.

[0022] The workbench 100 refers to the base platform supporting the detection components, which can be made of cast iron or welded steel structure, and its surface can be set with a positioning reference surface. The control box refers to the data processing unit, which can be implemented using a PLC or embedded controller, used to receive sensor signals and calculate height differences. The display device 300 refers to the human-machine interface, which can be implemented using an LCD screen, used to display measurement data in real time. The first support base 400 refers to the positioning component fixed to the workbench 100, which can be made of hard alloy material, and its top end face forms the product support reference surface. The abutment rod 500 refers to the axially movable detection contact, which can be implemented using a stainless steel rod with a linear bearing, and its end has a spherical contact head to adapt to different product contours. The detection sensor refers to the displacement detection device, which can be implemented using an infrared ranging sensor or an LVDT displacement sensor, and its signal output terminal is electrically connected to the control box. The downward drive 610 refers to the linear power device, which can be implemented using a cylinder or electric push rod, and its output terminal is connected to the pressure block 620 to apply vertical pressure. The clamping block 620 refers to the clamping actuator, which can be made of nylon or polyurethane material, and its contact surface is provided with anti-slip texture to increase friction.

[0023] Specifically, during operation, the workpiece is placed on the support surface formed by the first support base 400 and the abutment rod 500. After the downward drive 610 is activated, it pushes the pressure block 620 downwards, clamping the workpiece between the pressure block 620 and the support base to form a stable contact. At this time, the bottom surface of the product is completely in contact with the reference surface of the support base, eliminating measurement errors caused by tilting due to its own weight. The abutment rod 500 generates axial displacement based on the height difference of the product surface. The detection sensor collects the displacement in real time and transmits it to the control box. The control box converts the displacement signal into a height difference value and outputs it on the display device 300. The entire process requires no manual adjustment of the measuring point position; mechanical positioning and automatic clamping ensure the consistency of the measurement reference.

[0024] Compared to existing technologies, traditional dial indicator testing requires operators to manually fix the product and measure point by point. This solution achieves automatic product positioning through a mechanical clamping mechanism. Existing technologies often rely on a single support point, leading to product wobbling. This solution uses a multi-point support structure combined with downward clamping to create a stable measurement benchmark. Traditional methods depend on manual readings, which introduces subjective errors. This solution achieves objective data processing through automatic sensor signal acquisition.

[0025] Beneficially, this application effectively eliminates measurement errors caused by unstable product clamping, achieving automated operation of height difference detection. During the detection process, the measured part maintains stable contact with the supporting reference surface, avoiding random errors caused by manual adjustments. Automatic sensor data acquisition and processing significantly improves detection efficiency, reducing single measurement time by approximately 60% compared to traditional methods. The entire equipment operation requires no intervention from professional technicians, reducing reliance on operator skill levels.

[0026] According to some embodiments of this application, a return spring 700 is also included, which is mounted on the worktable 100 and connected to the abutment rod 500.

[0027] The return spring 700 is an elastic element installed between the abutment rod 500 and the worktable 100. It can be implemented using a helical spring or a leaf spring. Its function is to provide restoring force to the abutment rod 500, allowing it to automatically return to its initial position after testing. The abutment rod 500 is a support component movably installed on the first support base 400. It can be implemented using a sliding rod or a hinged rod. Its function is to contact the surface of the product to be tested and transmit displacement signals to the detection sensor.

[0028] Specifically, when the contact rod 500 shifts due to the height difference on the product surface, the return spring 700 is compressed or stretched to store elastic potential energy. After the detection action is completed, the return spring 700 releases the stored elastic potential energy, driving the contact rod 500 back to its initial position along the movement path. This process requires no manual intervention, ensuring that the contact rod 500 is in the preset reference position before each detection, eliminating measurement errors caused by positional deviations. The elastic coefficient of the return spring 700 can be adjusted according to the product weight and detection pressure, for example, by using springs with different wire diameters to meet the detection requirements of products of different specifications.

[0029] Compared to existing technologies, traditional testing equipment requires manual reset of the contact rod 500 or relies on gravity for reset, resulting in slow reset speed and low positional accuracy. This solution utilizes a spring-driven active elastic reset mechanism to enable the contact rod 500 to achieve rapid and accurate reset within the testing cycle, avoiding reset delays or positional deviations caused by manual operation. This is particularly suitable for continuous batch testing scenarios.

[0030] Beneficially, this application implements an automatic reset function for the abutment rod 500, ensuring the consistency of the support position during testing and resolving the issue of data fluctuations caused by untimely reset. Simultaneously, it reduces manual intervention, shortens the single testing cycle, and improves testing efficiency.

[0031] According to some embodiments of this application, the first support 400 is provided with a first abutting part and a second abutting part, the first abutting part being limited and abutting with a first protrusion of the product to be tested, and the second abutting part being limited and abutting with a second protrusion of the product to be tested.

[0032] The first abutment refers to a physical limiting structure set on the first support 400, which can be implemented using an adjustable protrusion or groove structure to constrain the lateral displacement of the first protrusion of the product. The second abutment refers to an independent limiting structure spatially separated from the first abutment, which can be implemented using a positioning pin or claw structure symmetrically arranged with the first abutment to constrain the longitudinal displacement of the second protrusion of the product. The combination of the first abutment and the second abutment forms a two-point positioning system, and the spatial distance between them is preset according to the distribution characteristics of the product's detection surface.

[0033] Specifically, when the product to be tested is placed on the first support base 400, the downward drive 610 pushes the pressure block 620 to press the product against the first support base 400. At this time, the contact surface between the first protrusion and the first abutment forms a first constraint point, and the contact surface between the second protrusion and the second abutment forms a second constraint point. The two constraint points respectively restrict the product's displacement freedom in two orthogonal directions, forming a planar positioning reference. During the testing process, the tilting moment generated by the product's own center of gravity shift is absorbed by the double-point support structure, and the first abutment and the second abutment together maintain the horizontal state of the product's testing surface. The relative positions of the first abutment and the second abutment are matched according to the actual height difference distribution of the product's testing surface to ensure that both testing surfaces of the product maintain perpendicular contact with the abutment rod 500 simultaneously under pressure.

[0034] Compared to existing technologies, traditional testing equipment uses a single-point support method, which can easily cause the testing surface to tilt due to the shift in the center of gravity when the product is under pressure. For example, the testing surfaces 1 and 2 of the pressure-reducing cam rocker arm may produce measurement errors due to the complex distribution of the stepped surfaces. In contrast, this solution uses a dual-point positioning structure to simultaneously constrain the two key protruding parts of the product, ensuring that the testing surfaces maintain a stable posture during pressure application and eliminating the measurement reference offset caused by the asymmetry of the product's own structure.

[0035] Beneficially, this application effectively solves the problem of product tilting caused by unstable center of gravity during testing, ensuring that the two testing surfaces are always on a preset reference plane during measurement. The displacement detection data of the abutment rod 500 directly reflects the actual height difference of the product surface, avoiding measurement errors caused by product tilting and significantly improving the repeatability and accuracy of the test results.

[0036] According to some embodiments of this application, the testing mechanism further includes a limiting block 800, which is disposed on one side of the first support 400. The side wall of the limiting block 800 abuts against the side wall of the product to be tested, and the limiting block 800 is used to prevent the product to be tested from falling off the abutment rod 500.

[0037] The limiting block 800 refers to a physical constraint structure installed on the side of the first support base 400. Specifically, it can be a metal or plastic block fixed to the side wall of the first support base 400 with bolts, and its height matches the height of the side wall of the product to be tested. Side wall contact means that the inner plane of the limiting block 800 forms a surface contact with the side wall of the product. The contact area can be adjusted according to the product size, for example, using an arc-shaped contact surface to adapt to a cylindrical product.

[0038] Specifically, when the product to be tested is placed on the abutment rod 500, the product's sidewall automatically contacts the limiting block 800, forming a lateral constraint. When the pressing mechanism 600 applies vertical pressure, the lateral displacement component that the product may generate is blocked by the limiting block 800, while the longitudinal freedom of movement of the abutment rod 500 is preserved. The relative position of the limiting block 800 and the first support seat 400 is preset according to the product's shape. For example, for a pressure-reducing cam rocker arm with a symmetrical structure, the limiting blocks 800 are symmetrically distributed on both sides of the support seat. This arrangement ensures that the product is always in a three-dimensional spatial constraint state during the testing process, preventing slippage due to a shift in the center of gravity.

[0039] Compared to existing technologies, traditional testing methods rely on operators manually straightening the product to prevent tilting, while the limit stop 800 automatically completes positioning through mechanical constraints. Existing technologies using dial indicators require multiple adjustments to the product position, while this solution, through the synergistic action of the limit stop 800 and the abutment rod 500, achieves stable testing with a single placement.

[0040] Beneficially, this application effectively prevents measurement errors and equipment damage caused by accidental product slippage during testing, ensuring the stability and repeatability of test data. Simultaneously, the limit stop 800 simplifies the product positioning process, eliminating the need for continuous manual product alignment by the operator and significantly improving testing efficiency.

[0041] According to some embodiments of this application, the pressing mechanism 600 further includes a second support 630, which is disposed on the same side as the pressing drive 610 and is located below the pressure block 620. The second support 630 is used to support the end of the product to be tested that extends out of the first support 400.

[0042] The second support base 630 is a supporting component arranged on the same side as the pressure block 620. It can be implemented using a height-adjustable column structure, with a groove at the top matching the shape of the product's end. Its function is to provide physical support for the product's suspended end, preventing bending due to gravity or external forces during pressing. The area below the pressure block 620 refers to the area covered by the vertical projection of the pressure block 620's movement trajectory. The positional correspondence between the pressure block 620 and the second support base 630 can be achieved using positioning pins or guide grooves. Its function is to ensure that when the pressure block 620 is pressed down, the second support base 630 simultaneously provides effective support for the product's extended end.

[0043] Specifically, when the pressure block 620 moves downward under the action of the downward drive 610, the product to be tested is pushed towards the first support base 400. At this time, the end of the product extending out of the first support base 400 is supported by the groove on the top of the second support base 630, forming a three-point support structure: the first support base 400 limits the main body of the product, the second support base 630 supports the extended end, and the pressure block 620 applies vertical pressure. The three-point support keeps the product in a horizontal position during the testing process, avoiding deformation or displacement due to suspension on one side. The detection sensor can accurately calculate the height difference of the product surface by measuring the displacement of the abutment rod 500.

[0044] Compared with existing technologies, traditional testing equipment relies solely on the pressure block 620 and the first support base 400 to form a two-point clamping structure. The product's suspended end lacks support and is prone to elastic deformation, resulting in tilting of the testing surface. This solution adds a second support base 630 to form a three-point support structure, eliminating the influence of gravity on the suspended end and ensuring stable contact of the product during compression, providing a deformation-free measurement reference for the testing sensor.

[0045] Beneficially, this application solves the deformation problem caused by lack of support at the product's extended end, ensuring uniform force on each end face of the product during the testing process. This ensures that the displacement data collected by the detection sensor truly reflects the height difference of the product surface, thereby improving the repeatability and accuracy of the measurement results.

[0046] According to some embodiments of this application, the testing mechanism further includes a first support 900, which is fixed on the workbench 100, and the abutment rod 500 is connected to the first support 900.

[0047] The first bracket 900 refers to a rigid structure that provides installation support for the abutment rod 500. Specifically, it can be implemented using a welded or bolted metal frame, and its function is to enhance the installation stability of the abutment rod 500. The connection between the abutment rod 500 and the first bracket 900 means that the abutment rod 500 is movably mounted on the bracket through a hinged or sliding fit. Specifically, it can be implemented using a pin connection or a guide rail structure, and its function is to allow the abutment rod 500 to move vertically while limiting its horizontal offset.

[0048] Specifically, the first bracket 900 is fixedly installed at a preset position on the worktable 100, forming a rigid constraint on the abutment rod 500. When the product to be tested is pushed by the pressing mechanism 600 to abut against the first support base 400, the product surface contacts the abutment rod 500 and applies pressure, at which point the abutment rod 500 displaces in the vertical direction. Due to the fixing effect of the first bracket 900, the abutment rod 500 can only move in a preset direction, avoiding lateral swaying caused by external forces. The detection sensor collects the displacement data of the abutment rod 500 in real time and, combined with the limiting reference of the first support base 400, calculates the height difference between different detection points on the product surface.

[0049] Compared to existing technologies, in traditional testing equipment, the contact rod 500 is directly mounted on the worktable 100 or support base, lacking the rigid constraint of an independent bracket. During testing, it is prone to swaying due to product center of gravity shift or external interference, causing the support point position to change. This solution, however, adds a first bracket 900, directly connecting the mounting base of the contact rod 500 to the worktable 100. This preserves the freedom of movement of the contact rod 500 while eliminating displacement interference in non-testing directions.

[0050] The advantage of this application is that it can ensure that the abutment rod 500 maintains a stable support position during the testing process, avoiding the deviation of the testing reference caused by loose installation structure or external force interference, thereby improving the repeatability accuracy of height difference testing and reducing measurement errors caused by unstable support.

[0051] According to some embodiments of this application, the first support 400 is provided with a movable channel, and one end of the abutment rod 500 passes through the movable channel; When the abutment rod 500 is in a non-working state, the end of the abutment rod 500 is higher than the top end face of the first support 400.

[0052] The movable channel refers to a guide structure located inside or on the surface of the first support 400. Specifically, it can be implemented using a rectangular through-hole, a circular through-hole, or a groove structure. Its inner wall forms a clearance fit or sliding fit with the surface of the abutment rod 500. This channel physically restricts the freedom of movement of the abutment rod 500, allowing it to move linearly only in a preset direction. The end of the abutment rod 500 being higher than the top surface of the support 400 refers to the vertical height difference between the top of the abutment rod 500 and the bearing surface of the support 400 when no external force is applied. This can be achieved through a spring return mechanism or a gravity balance structure. This design ensures a clear spatial relationship between the initial position of the abutment rod 500 and the support 400 during product placement, preventing direct contact between the product's bottom surface and the support 400, which could lead to confusion in the positioning reference.

[0053] Specifically, when the operator places the product to be tested onto the equipment, the bottom surface of the product first contacts the end of the non-working abutment rod 500. At this time, because the end of the abutment rod 500 is higher than the top surface of the support base, the product is suspended in mid-air. When the pressing mechanism 600 drives the pressure block 620 to push the product downward, the abutment rod 500 slides downward along the movable channel until the product's testing surface is completely in contact with the top end face of the support base. The guiding effect of the movable channel strictly limits the movement trajectory of the abutment rod 500 to the vertical direction, eliminating the influence of lateral offset on the testing reference. The displacement of the abutment rod 500 is converted into height difference data by a sensor, ensuring that the measurement reference is always based on the top surface of the support base as a unified reference plane.

[0054] Compared to existing technologies, traditional detection devices lack a guiding structure for the abutment rod 500, making it prone to tilting or shifting during product pressing, resulting in non-vertical components in the displacement data collected by the sensor. This solution, however, uses the physical constraint of the moving channel to ensure the abutment rod 500 can only move in a single direction, fundamentally eliminating lateral displacement errors. Furthermore, the design of the abutment rod 500's initial position higher than the support base avoids positioning deviations caused by accidental contact with the support base surface during manual product placement, making the establishment of the detection benchmark more controllable.

[0055] Beneficially, this application enables automatic calibration of the reference surface during product positioning, eliminating the impact of human error on the test results. The guiding movement of the abutment rod 500, combined with the initial position design, ensures that the product always uses the top surface of the support base as a unified reference during the testing process, guaranteeing the accuracy and repeatability of height difference measurement data, while simplifying the operation process.

[0056] According to some embodiments of this application, the pressing mechanism 600 further includes a second bracket 640, which is detachably connected to the worktable 100, and the pressing drive 610 is mounted on the second bracket 640.

[0057] The second bracket 640 refers to the support structure used to support the downward drive 610. Specifically, it can be formed by welding metal frames or plates and is detachably connected to the worktable 100 by bolts. Detachable connection means that the second bracket 640 and the worktable 100 are mechanically fixed in a separable manner, such as by the cooperation of positioning pins and slots, or by locking with quick-release clamps.

[0058] Specifically, the second bracket 640 is installed as an independent module on the edge of the workbench 100, and its height and horizontal position can be adjusted by adjusting the connection holes. When it is necessary to adapt to products of different sizes, the second bracket 640 can be disassembled and repositioned so that the pressure block 620 of the pressure drive 610 is aligned with the product inspection area. During maintenance of the pressure drive 610, only the second bracket 640 needs to be disassembled as a whole to remove it from the working area, avoiding interference with the inspection mechanism. Through the separate design of the bracket and the workbench 100, the installation position of the pressure drive 610 is no longer limited by the inherent structure of the workbench 100, while the rigid support of the bracket ensures a stable downward pressure transmission path.

[0059] Compared to existing technologies, the traditional pressing drive 610 is directly fixed to the surface of the worktable 100, requiring re-drilling or welding for position adjustment, resulting in a long equipment modification cycle. This solution, however, achieves modular installation of the pressing drive 610 through a detachable bracket, allowing for position adjustment without modifying the main structure of the worktable 100, significantly shortening equipment adjustment time.

[0060] Beneficially, this application solves the problem of poor equipment adaptability caused by the fixed installation structure of the pressure drive 610, realizes rapid position adjustment and independent maintenance of the pressure mechanism 600, reduces equipment modification and maintenance costs, and improves the compatibility of the testing equipment with different products.

[0061] According to some embodiments of this application, the operation button 1000 is installed on the workbench 100 and connected to the control box. The operation button 1000 is used to control the start and stop of the pressure drive 610.

[0062] The operation button 1000 is a control element with a physical trigger function, which can be implemented using an emergency stop switch with mechanical travel or a membrane keypad. Its contacts form an electrical connection with the input port of the control box. The control box connection refers to establishing a control loop between the operation button 1000 and the pressure drive 610 via signal cables. This can be achieved using a PLC controller for signal transmission and logic control. The start / stop control of the pressure drive 610 refers to controlling the energization and de-energization of the drive motor through the trigger signal of the operation button 1000. This can be achieved using a relay module to close and open the power circuit.

[0063] Specifically, when operation button 1000 is triggered, the control box receives an electrical signal and pushes down drive 610 to output a start command, driving pressure block 620 to perform a pressing action. After the detection is completed, triggering operation button 1000 again will send a stop command, causing pressure block 620 to reset to its initial position. The linkage design between operation button 1000 and the control box allows the timing and duration of the pressing action to be precisely controlled by a preset program, eliminating detection errors caused by differences in pressing time during manual operation.

[0064] In some specific embodiments, the operation button 1000 can be integrated into the operation panel on the edge of the workbench 100, forming a human-machine interface with the display device 300. The button trigger area can be provided with an anti-accidental touch flange, and the button surface can be covered with a silicone protective layer with start / stop markings. The control box can be configured with a time-delay relay module, enabling the pressure drive 610 to perform a buffered retraction action after receiving a stop command.

[0065] Compared to existing technologies, traditional testing equipment requires the pressure drive 610 to be operated via a separate control cabinet or foot switch, necessitating operators to move between different workstations and manually adjust pressure parameters. This solution integrates the operation button 1000 into the workbench 100, achieving single-point control and programmed execution, thus avoiding uneven pressing force or response delays caused by distraction during manual operation.

[0066] The advantage of this application is that it enables standardized control of the pressing action during the testing process, reduces the need for operators to perform multi-point operations on the equipment, eliminates fluctuations in test data caused by differences in human operation rhythm, and ensures the consistency of testing conditions for different batches of products.

[0067] According to some embodiments of this application, the detection sensor is an infrared ranging sensor. An infrared ranging sensor is a device that uses infrared light for non-contact distance measurement; specifically, it can calculate distance by emitting an infrared beam and receiving the reflected signal. This sensor directly measures the displacement change of the contact rod 500 in a non-contact manner, avoiding the mechanical friction error caused by the contact between traditional contact sensors and the surface of the product being measured, thereby improving detection accuracy.

[0068] Specifically, the infrared ranging sensor emits an infrared beam to the movable end of the contact rod 500 and receives the reflected signal to calculate the displacement distance in real time. Since no physical contact is required, tilting of the product due to a shift in the center of gravity will not affect the measurement results. Simultaneously, the sensor data is directly transmitted to the control box via electrical signals, where it is digitally processed by the display device 300. This method eliminates the interference of human operation in the measurement process; for example, traditional dial indicators require manual adjustment of the contact pressure, while infrared ranging achieves rapid multi-point detection through automatic data acquisition.

[0069] Compared to existing technologies, traditional contact sensors require manual adjustment of the contact position and pressure by operators, which can easily lead to measurement errors due to product tilting or uneven force application. In contrast, infrared ranging sensors directly acquire displacement data through non-contact measurement, eliminating the need for contact with the measured surface. This avoids mechanical friction errors and reduces human intervention, thereby significantly improving detection efficiency and result consistency.

[0070] Beneficially, this application solves the problems of large measurement errors and low detection efficiency caused by product tilting or human operation in traditional contact detection, realizes non-contact high-precision displacement detection, and provides hardware support for automated detection processes.
