Description

Technical Field

[0001] This invention relates to the field of inspection tooling technology, and more specifically, to a multi-purpose inspection tool. Background Technology

[0002] Inspection fixtures are tools used in automated stamping production to monitor and inspect whether stamped parts are qualified. Traditional inspection fixtures can only inspect individual stamped parts and cannot inspect sub-assemblies that have been welded and riveted together. For example, a fender sub-assembly needs to be inspected by a separate sub-assembly fixture. As a result, in the traditional design, a component and a component assembly need to be inspected separately. On the one hand, the error dimensions of the inspection fixture itself accumulate, and on the other hand, the cost of two sets of inspection fixtures increases, while also occupying production line space. There is room for improvement. Summary of the Invention

[0007] In some embodiments, the detection element is located at one end of the reference member in its direction of movement, and the reference member is further provided with a holding portion, which is arranged at a distance from the detection element.

[0008] In some embodiments, the reference member has a first locking hole, the guide member has a second locking hole, and the locking member passes through the first locking hole and the second locking hole to connect the guide member and the reference member.

[0009] In some embodiments, at least one of the first locking hole and the second locking hole may include a plurality; and / or, at least one of the first locking hole and the second locking hole may be an oblong hole.

[0010] In some embodiments, the detection device further includes: a positioning member disposed on the support platform and having a positioning surface, the positioning surface extending in a direction inclined to the surface of the support platform, and a guide member mounted on the positioning surface.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] The following is for reference. Figures 1-8 A multipurpose inspection tool 100 according to an embodiment of the present invention is described.

[0020] like Figures 1-8 As shown, a multi-purpose inspection fixture 100 according to an embodiment of the present invention includes: a support platform 10 and a plurality of inspection devices 20. The inspection devices 20 are disposed on the support platform 10, which is a support platform for the entire inspection fixture. A plurality of inspection devices 20 can be disposed on the support platform 10. The plurality of inspection devices 20 are arranged at intervals. Each inspection device 20 has a detection element 22. The plurality of detection elements 22 are used to monitor and inspect whether the workpiece to be inspected is qualified. The plurality of detection elements 22 can be partially the same and partially different to meet the different inspection requirements of different positions of a workpiece to be inspected.

[0021] At least one detection device 20 includes a fixed bracket 21 and a detection element 22. The fixed bracket 21 is mounted on a support platform 10 and has a reference member 211. The detection element 22 is mounted on the reference member 211. The reference member 211 is movable between a first position and a second position. The reference member 211 serves as a reference point for the detection position of the detection element 22. The movement of the reference member 211 causes a change in the position of the reference point, thereby allowing the detection element 22 to be located at different positions on the support platform 10. This enables the detection or avoidance of the part to be detected. For example, when the reference member 211 is in the first position, the detection element 22 can be used to detect the first part to be detected, thereby ensuring the accuracy of the detection of the first part to be detected. When the reference member 211 is in the second position, the detection element 22 can avoid the second part to be detected, thereby preventing interference between the detection element 22 and the second part to be detected. The first part to be detected and the second part to be detected can be a single part and a part assembly or sub-assembly, such as a fender and a fender sub-assembly.

[0022] According to an embodiment of the present invention, the multi-purpose inspection fixture 100, by providing a movable reference member 211 on the fixed bracket 21, drives the movement of the detection element 22 through the movement of the reference member 211, so that the detection element 22 can not only inspect some items, but also reduce interference with other items through movement. Thus, through a simple structural design, it is possible to inspect different items without excessively increasing the manufacturing cost of the inspection fixture, and can use one set of inspection fixtures to inspect multiple items, reducing the problem of reduced detection accuracy caused by the error of the inspection fixture itself, while saving space.

[0023] like Figures 2-8As shown, in some embodiments, the fixed bracket 21 further includes a guide 212 and a locking member 213. The guide 212 is disposed on the support platform 10, and the reference member 211 is disposed on the guide 212. The reference member 211 and the guide 212 are slidably engaged, thereby realizing the movement of the reference member 211 between a first position and a second position. When the reference member 211 slides, it drives the detection element 22 to slide, thereby enabling the detection element 22 to detect different items to be detected or to avoid some items to be detected. The sliding operation is convenient and facilitates the rapid switching of the inspection tool.

[0024] The locking member 213 cooperates with the guide member 212 and the reference member 211. The locking member 213 is used to lock the reference member 211 in the first position and the second position, thereby fixing the reference member 211 on the guide member 212 and preventing the reference member 211 from shaking and affecting the accuracy of the detection element 22.

[0025] Therefore, the design of guide 212 and locking 213 facilitates the rapid movement of reference 211, enables rapid switching of inspection fixtures, and facilitates the testing and verification of fenders and similar components such as sub-assemblies on the same inspection fixture, thereby achieving the effect of cost reduction and efficiency improvement.

[0026] In other embodiments, the reference member 211 is disposed on the guide member 212, and the reference member 211 and the guide member 212 are rotatably engaged, thereby realizing the movement of the reference member 211 between a first position and a second position. When the reference member 211 rotates, it drives the detection element 22 to rotate, thereby enabling the detection element 22 to detect different items to be detected or to avoid some items to be detected.

[0027] like Figure 3 and Figure 4 As shown, in some embodiments, the detection element 22 is located at one end of the reference member 211. For example, the reference member 211 moves along a first direction, and the detection element 22 is located at one end of the reference member 211 in the first direction, thereby avoiding interference and collision between the movement of the reference member 211 and the detection element 22. The reference member 211 is also provided with a holding part 2111. By providing the holding part 2111, the movement of the reference member 211 is facilitated, and the convenience of using the multi-purpose inspection tool 100 is improved.

[0028] The gripping part 2111 and the detection element 22 are arranged at a distance. By separating the gripping part 2111 from the detection element 22, it is easier to operate the gripping part 2111 and the convenience of operation is improved; for example, Figure 4 As shown, the gripping part 2111 is provided at the other end of the reference member 211 in the first direction, thereby facilitating the operation of the gripping part 2111 and avoiding interference with the detection element 22 during operation.

[0029] like Figure 5As shown, in some embodiments, the guide member 212 defines a guide groove 2121, with both ends of the guide groove 2121 open in the extending direction. The reference member 211 passes through the guide groove 2121, and the extending direction of the guide groove 2121 is the moving direction of the reference member 211. In the extending direction of the guide groove 2121, the detection element 22 is disposed at one end of the reference member 211, and the other end of the reference member 211 is provided with a holding part 2111. Thus, both the detection element 22 and the holding part 2111 are located outside the guide groove 2121, so that the guide member 212 will not affect the operation of the reference member 211, and at the same time will not affect the detection effect of the detection element 22.

[0030] In addition, the guide groove 2121 of the guide member 212 is designed to be open at both ends, which facilitates the installation of the reference member 211.

[0031] like Figure 7 and Figure 8 As shown, in some other embodiments, the guide member 212 defines a guide groove 2121 and a clearance groove 2122. One end of the guide groove 2121 is open in the extending direction. The clearance groove 2122 is located on one side of the guide groove 2121 and communicates with the guide groove 2121. The reference member 211 passes through the guide groove 2121. One end of the reference member 211 extends out of the guide groove 2121 and is provided with a detection element 22. The gripping part 2111 is located in the middle of the reference member 211 and extends out of the guide member 212 through the clearance groove 2122 to facilitate the operator's gripping operation.

[0032] In other words, one end of the guide groove 2121 is open and the other end is blocked. This can be achieved by the guide member 212 itself being blocked, or by the guide member 212 being installed on the support platform 10 and blocked by the support platform 10. By blocking one end of the guide groove 2121, only one end of the guide member 212 extends out of the guide groove 2121, and most of the reference member 211 is located inside the guide member 212. This helps to improve the guiding effect of the guide member 212 on the reference member 211 and improve the stability of the reference member 211's movement. By setting the clearance groove 2122 on the guide member 212, the reference member 211 can be fitted with the gripping part 2111, which facilitates the operator's gripping operation and improves the convenience of switching the position of the reference member 211.

[0033] like Figure 5 and Figure 8 As shown, in some embodiments, the reference member 211 has a first locking hole 2112, the guide member 212 has a second locking hole 2123, and the locking member 213 passes through the first locking hole 2112 and the second locking hole 2123, thereby connecting the guide member 212 and the reference member 211. The overall structure is simple, the assembly is convenient, and the convenience of switching the multi-purpose inspection tool 100 is improved.

[0034] like Figure 5 and Figure 8 As shown, in some embodiments, at least one of the first locking hole 2112 and the second locking hole 2123 may include multiple locking holes. That is, the reference member 211 may have one first locking hole 2112 and the guide member 212 may have multiple second locking holes 2123, or the reference member 211 may have multiple first locking holes 2112 and the guide member 212 may have one second locking hole 2123, or the reference member 211 may have multiple first locking holes 2112 and the guide member 212 may have multiple second locking holes 2123. Thus, by passing the locking member 213 through different first locking holes 2112 and second locking holes 2123, the reference member 211 can be locked in different positions. The locking hole structure is simple and easy to manufacture.

[0035] In some other embodiments, at least one of the first locking hole 2112 and the second locking hole 2123 is an oblong hole, that is, the first locking hole 2112 can be an oblong hole and the second locking hole 2123 can be a circular hole, or the first locking hole 2112 can be a circular hole and the second locking hole 2123 can be an oblong hole, or the first locking hole 2112 can be an oblong hole and the second locking hole 2123 can also be an oblong hole. The locking member 213 can slide relative to the oblong hole, thereby locking the reference member 211 in different positions. By opening the oblong hole, the number of holes can be reduced, which improves manufacturing efficiency on the one hand, and the locking member 213 does not need to be completely disassembled, making operation convenient.

[0036] like Figures 2-5 As shown, in some embodiments, the fixed bracket 21 further includes a positioning member 214, which is disposed on the support platform 10 and has a positioning surface 2141. The extending direction of the positioning surface 2141 is inclined to the surface of the support platform 10. This inclination can be an acute angle or a vertical angle. The guide member 212 is mounted on the positioning surface 2141. By designing the positioning member 214 with the positioning surface 2141, the guide member 212, the reference member 211, and the detection element 22 are supported, facilitating the interaction between the detection element 22 and the reference member 211. On the one hand, the cooperation of the part to be inspected; on the other hand, the sliding direction of the reference part 211 is limited by the tilt angle of the positioning surface 2141, so that the reference part 211 can move in a space that does not interfere with the part to be inspected. That is, the entire multi-purpose inspection fixture 100 can be designed with multiple guide parts 212 and reference parts 211 with the same structure. By designing the tilt angle of the positioning surface 2141 of the positioning part 214, the reference parts 211 on each guide part 212 can move freely after being installed on the positioning part 214, thereby reducing the manufacturing cost of the entire multi-purpose inspection fixture 100.

[0037] In other embodiments, the guide member 212 can be directly mounted on the support platform 10. The guide member 212 can directly define the guide groove 2121 with a predetermined extension direction to define the position of the reference member 211, thereby reducing the number of parts and reducing manufacturing costs.

[0038] In some specific embodiments, the detection element 22 includes a hole position detection element, which can use vision or laser to quickly find the center of the "black hole" in order to detect the hole position accuracy on the workpiece.

[0039] In some specific embodiments, the detection element 22 includes a contour detection element, which can use laser scanning to compare the cross-sectional shape of the part to be inspected with the drawing to detect whether there are gaps, burrs or bending angle deviations in the outer contour of the part to be inspected.

[0040] In some specific embodiments, the detection element 22 includes a surface difference detection element, which can detect the outer surface of the test piece by using two lasers or confocal probes to detect the step difference and gap between adjacent parts of the test piece.

[0041] In some embodiments, the multipurpose inspection fixture 100 further includes a clamping device, which is disposed on the support platform 10 and is arranged at a distance from the inspection device 20. The clamping device can clamp any type of workpiece to be inspected to fix the workpiece to be inspected on the support platform 10, thereby improving the stability of the workpiece during the inspection process and thus improving the accuracy of the inspection.

[0042] like Figures 1-8 As shown, in some specific embodiments, the multi-purpose inspection fixture 100 includes a support platform 10 and multiple detection devices 20. Some detection devices 20 include fixed brackets 21 and detection elements 22. Some fixed brackets 21 are composed of a reference member 211, a guide member 212, and a locking member 213. The guide member 212 is directly mounted on the support platform 10. Other fixed brackets 21 are composed of a reference member 211, a guide member 212, a locking member 213, and a positioning member 214. The positioning member 214 is mounted on the support platform 10 and has a positioning surface 21. 41. The guide member 212 is installed on the positioning surface 2141 of the positioning member 214. In addition, the guide member 212 forms a guide groove 2121. The reference members 211 are all disposed in the guide member 212 and can slide in the guide groove 2121. The locking member 213 cooperates with the guide member 212 and the reference members 211. The locking member 213 is used to lock the reference members 211 in the first position and the second position, thereby fixing the reference members 211 on the guide member 212 and preventing the reference members 211 from shaking and affecting the accuracy of the detection element 22.

[0043] The reference member 211 has a first locking hole 2112, and the guide member 212 has a second locking hole 2123. When the reference member 211 slides to the first position, the locking member 213 passes through the first locking hole 2112 and the second locking hole 2123, thereby connecting the guide member 212 and the reference member 211. At this time, the first test piece can fit with the detection element 22, so that the detection element 22 can detect the first test piece and ensure the accuracy of the detection of the first test piece.

[0044] When the reference piece 211 can slide to the second position, the guide piece 212 and the reference piece 211 are connected by the locking piece 213 passing through another first locking hole 2112 and a second locking hole 2123. This increases the placement space on the multi-purpose inspection tool 100, so that after another item to be inspected is placed, the detection element 22 can play a role in avoiding interference.

[0045] Before using the multi-purpose inspection fixture 100, check that the fixture is clean and free of residue or foreign matter that may interfere with the measurement. Move all the reference parts 211 of the inspection devices to the second position. When inspecting a single piece, drag the reference part 211 to the first position using the handle 2111 and lock it using the locking part 213. Then, install the piece to be inspected on the fixture and confirm that the piece to be inspected and the inspection element 22 are properly aligned. Clamp the single piece to be inspected using the clamping device, and then position the part and close the clamps and measuring blocks according to the GDT sequence. After confirmation, the inspection can begin.

[0046] When inspecting a single sub-assembly, fix the reference part 211 in the second position, then install the single sub-assembly to be inspected on the inspection fixture, confirm that the single sub-assembly to be inspected is spaced apart from the inspection element 22, then clamp the single sub-assembly to be inspected through the clamping device, and position the part and close the clamp and measuring block in sequence according to the GDT sequence. After confirmation, the inspection can begin.

[0047] Therefore, by using a single multi-purpose gauge 100 to meet the measurement needs of individual parts and sub-assemblies, the traditional method of separating gauges and sub-assembly gauges into two separate systems is achieved. By adding a few structural components and allowing the reference component 211 to move and avoid interference, the measurement of individual parts and sub-assemblies can be carried out using the same testing tool. This eliminates the need for two dedicated gauges, reducing the space occupied and errors associated with different gauges. It also improves the efficiency of the multi-purpose gauge 100, eliminates the need to purchase two sets of testing equipment and reduces the cost of floor space, achieving cost reduction throughout the entire life cycle. By using one gauge in two ways, measurement errors are reduced, the need for operator calibration and fitting is reduced, and manual efficiency is improved, further achieving cost reduction and efficiency improvement.

[0048] Other configurations and operations of the multipurpose gauge 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here. The vertical, horizontal, and front-back directions are defined as shown in the figures.

[0049] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention.
