Description

Technical Field

[0001] This utility model relates to the field of testing equipment for aluminum alloy processing, specifically a rapid testing device for the flatness of aluminum plates. Background Technology

[0002] In modern industrial production, aluminum sheets, as an important metallic material, are widely used in aerospace, automobile manufacturing, and architectural decoration due to their many excellent properties such as low density, high strength, and corrosion resistance. In these applications, the flatness of aluminum sheets is a crucial quality indicator. In the aerospace field, the flatness accuracy of aluminum sheets directly affects the assembly precision of aircraft parts, thus impacting flight safety. In the architectural decoration field, the flatness of aluminum sheets determines the aesthetics and stability of decorative structures such as curtain walls. Therefore, accurate and rapid detection of aluminum sheet flatness is of great significance for ensuring product quality, improving production efficiency, and reducing production costs.

[0003] Currently, there are two main methods for inspecting the flatness of aluminum plates: manual inspection and instrument inspection. Manual inspection often uses simple tools such as straightedges and plug gauges to determine flatness by measuring the gap between the aluminum plate surface and a reference plane. This method is simple to operate and has a low cost. As for instrument inspection, coordinate measuring machines (CMMs) have the advantage of high precision and can accurately calculate flatness by collecting the three-dimensional coordinates of multiple points on the aluminum plate surface. Laser interferometers, based on the principle of laser interference, can achieve ultra-high precision inspection at the nanometer level. Online laser scanning inspection devices can perform rapid and continuous scanning inspection of aluminum plates in a production line environment, meeting the inspection needs of mass production.

[0004] However, when using a coordinate measuring machine to inspect multiple aluminum plates of the same specifications, although the measurement accuracy is high, the direct placement of the aluminum plates by hand is prone to position and orientation errors, which leads to the need to re-establish the coordinate system multiple times, greatly reducing the inspection efficiency. If a fixed fixture is used to ensure the accuracy of the aluminum plate placement, the fixture structure is too complex, requiring multiple components such as threaded connections and pressure blocks, which increases the complexity and cost of operation. In addition, frequent clamping operations also consume a lot of time. Therefore, a rapid aluminum plate flatness inspection device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a rapid aluminum plate flatness detection device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid aluminum plate flatness detection device, comprising a device body, an operating table, and a tooling plate placed on the operating table. The tooling plate has multiple sets of positioning holes, and positioning blocks are installed through these holes to restrict the position of the aluminum plate. A pin is fixedly installed at the bottom of the positioning block, and a support member is slidably installed on the inner wall of the pin. Two sets of support members are provided to fix the pin within the positioning holes. A first spring is fixedly installed on the inner side of the support member, and the two sets of support members are interconnected through the first spring. A fixing block is slidably installed on the inner wall of the positioning block, and a toggle plate is fixedly installed on the top of the fixing block to drive the fixing block to slide. A second spring is fixedly installed at the end of the fixing block near the toggle plate.

[0007] By adopting the above technical solution, the spring force drives the opening component to automatically reset and press against the positioning hole, realizing the insertion and fixing of the pin, which greatly shortens the installation time of the positioning block. Through the mechanical transmission of the actuating plate, the manual operation is transformed into the linear movement of the fixing block. The aluminum plate can be unlocked and fixed without the need for tools or disassembling the clamps, and the uniformity of the placement of multiple aluminum plates of the same specification is ensured. At the same time, the second spring ensures that it always applies a pushing force towards the aluminum plate to the fixing block, so that the positioning block can fit tightly against the surface of the aluminum plate. When replacing the aluminum plate, the elastic deformation of the second spring can realize the automatic reset of the pressure plate, thereby eliminating the step of manually adjusting the position of the pressure plate and further improving the operating efficiency.

[0008] Furthermore, guide blocks are fixedly installed at the top and bottom of the support member, and guide grooves corresponding to the guide blocks are opened on the inner wall of the pin.

[0009] By adopting the above technical solution, the guide groove can ensure that the guide block slides smoothly and prevent the expansion member from shifting left and right when sliding, thereby ensuring that the two sets of expansion members always move synchronously to both sides of the pin.

[0010] Furthermore, the initial width of the support member is greater than the diameter of the positioning hole, and the bottom end of the support member is designed with a slope, and the two sets of support members are designed symmetrically.

[0011] By adopting the above technical solution, the pin is ensured to be subjected to balanced force, avoiding excessive compression of the pin by the unilateral support component, which would cause the pin to tilt. This ensures that the pin and the positioning hole remain coaxial, thereby guaranteeing the perpendicularity of the positioning block to the tooling plate after installation and preventing the aluminum plate from being misaligned due to the positioning block.

[0012] Furthermore, a hinge plate is fixedly connected to one end of the fixing block near the aluminum plate, and a pressure plate is rotatably installed at the end of the hinge plate. Two sets of pressure plates are provided, and the two sets of pressure plates are V-shaped and hinged to the end of the hinge plate. A No. 3 spring is fixedly installed at the end of the fixing block near the hinge plate, and the fixing block and the pressure plate are connected to each other through the No. 3 spring.

[0013] By adopting the above technical solution, the No. 3 spring can adaptively extend and retract with the rotation of the pressure plate, ensuring that the pressure plate is always in close contact with the surface of the aluminum plate. Stable positioning of aluminum plates at different angles can be achieved without manual adjustment, thereby further expanding the application range of the device.

[0014] Furthermore, the positioning block is sleeved on the outer wall of the fixed block, and the top of the positioning block has an opening corresponding to the toggle plate, and the plane where the top of the toggle plate is located is higher than the plane where the top of the positioning block is located.

[0015] By adopting the above technical solution, the extended design of the toggle plate increases the operating contact area, making it easier for testing personnel to quickly apply force to drive the fixed block to slide.

[0016] In summary, the present invention has the following main advantages:

[0017] This invention utilizes the cooperation between the bottom pin of the positioning block and the positioning hole of the tooling plate, along with a support component and a No. 1 spring, to achieve quick installation and fixation. This eliminates complex threaded connections and significantly reduces clamping time, improves the efficiency of inspecting multiple aluminum plates of the same specification, ensures the uniformity of the placement of multiple aluminum plates, and meets batch inspection requirements. The hinge structure of the pressure plate and hinge plate, along with the No. 3 spring, work together to allow the positioning block to adaptively adjust according to the angle of the aluminum plate's edges and corners, solving the problem of positioning aluminum plates at different angles. No special tooling is required, improving versatility, reducing tooling costs, and broadening the application range of the device. (The components include a moving plate, a fixing block, and a No. 2 spring.) Working in tandem, when replacing aluminum plates, simply moving the lever plate allows the pressure plate to disengage from the aluminum plate. After release, the pressure plate automatically resets and secures the new aluminum plate, simplifying the replacement process, saving time, and improving the continuity and efficiency of testing. The precise positioning and rapid fixation of the positioning block ensures the stability of the aluminum plate during testing, providing a guarantee for high-precision flatness testing and improving the reliability of quality testing. The use of high-strength wear-resistant materials and long-life springs reduces component wear, extends service life, and lowers maintenance costs. At the same time, the universal design reduces investment in special tooling, and the ease of operation reduces personnel training costs, saving overall operating costs from multiple aspects.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Example 1

[0026] A rapid flatness detection device for aluminum plates, such as Figure 1-4As shown, the device includes a main body 1, which is equipped with an operating table. A tooling plate 2 is placed on the operating table. The tooling plate 2 has multiple sets of positioning holes 21, which are evenly distributed to meet the positioning requirements of aluminum plates 4 of different specifications. Positioning blocks 3 are installed on the tooling plate 2 through the positioning holes 21 to restrict the position of the aluminum plates 4. The cooperation between the positioning holes 21 and the positioning blocks 3 enables rapid positioning without complex calibration steps. A pin 31 is fixedly installed at the bottom of the positioning block 3, and a support is slidably installed on the inner wall of the pin 31. Part 311, the sliding fit between the expansion part 311 and the inner wall of the pin 31 provides the basis for its width adjustment, ensuring that the expansion part 311 can smoothly adapt to the diameter of the positioning hole 21. Two sets of expansion parts 311 are provided to fix the pin 31 in the positioning hole 21, ensuring that the pin 31 is subjected to balanced force and avoiding fixation deviation caused by unilateral force. The tight abutment between the expansion part 311 and the inner wall of the positioning hole 21 replaces the traditional threaded connection, eliminating the tedious operation of tightening bolts. A No. 1 spring 312 is fixedly installed on the inner side of the expansion part 311. Furthermore, the two sets of supporting members 311 are interconnected by a first spring 312. The elastic force of the first spring 312 drives the supporting member 311 to automatically reset and press against the positioning hole 21, realizing the insertion and fixation of the pin 31, which greatly shortens the installation time of the positioning block 3. A fixing block 32 is slidably installed on the inner wall of the positioning block 3, and a toggle plate 321 is fixedly installed on the top of the fixing block 32 to drive the fixing block 32 to slide. A second spring 322 is fixedly installed on one end of the fixing block 32 near the toggle plate 321, and the mechanical transmission of the toggle plate 321 is used to drive the fixing block 32 to slide. This system transforms manual operation into the linear movement of the fixed block 32, enabling the unlocking and fixing of the aluminum plate 4 without the need for tools or disassembling the clamps. It also ensures the uniformity of the placement of multiple aluminum plates 4 of the same specification. At the same time, the second spring 322 ensures that it always applies a pushing force towards the aluminum plate 4 to the fixed block 32, so that the positioning block 3 can fit tightly against the surface of the aluminum plate 4. When replacing the aluminum plate 4, the elastic deformation of the second spring 322 can realize the automatic reset of the pressure plate 325, thereby eliminating the step of manually adjusting the position of the pressure plate 325 and further improving the operating efficiency.

[0027] Please see Figure 1-4 Guide blocks 314 are fixedly installed at the top and bottom of the support member 311, and guide grooves 313 corresponding to the guide blocks 314 are opened on the inner wall of the pin 31. The guide grooves 313 can ensure that the guide blocks 314 slide smoothly and prevent the support member 311 from shifting left and right when sliding, thereby ensuring that the two sets of support members 311 always move synchronously to both sides of the pin 31. At the same time, the length of the guide grooves 313 is designed to cover the maximum sliding stroke of the support member 311, preventing the guide blocks 314 from sliding out of the groove and causing structural failure.

[0028] Please see Figure 1-4The initial width of the support member 311 is greater than the diameter of the positioning hole 21. When the pin 31 is inserted into the positioning hole 21, the symmetrically distributed support members 311 can simultaneously apply a clamping force from both sides of the inner wall of the positioning hole 21, locking it in place without the need for additional external force. This makes the pin 31 more firmly fixed in the positioning hole 21, preventing loosening or shaking after the pin 31 is inserted. Furthermore, the bottom end of the support member 311 is designed with a slope, which can convert the axial thrust of the pin 31 when it is inserted into the radial contraction force of the support member 311, ensuring that the support member 311 remains in place. Under the pressure of the positioning hole 21, it slides smoothly inward without the need for manual adjustment, achieving a quick installation effect of insertion guidance and compression retraction, which greatly reduces the operation difficulty of installing the positioning block 3. In addition, the two sets of supporting parts 311 are symmetrically designed to ensure that the pin 31 is subjected to balanced force and avoid excessive compression of the supporting part 311 on one side, which would cause the pin 31 to tilt. This keeps the pin 31 coaxial with the positioning hole 21, thereby ensuring the perpendicularity of the positioning block 3 to the tooling plate 2 after installation and preventing the positioning deviation of the aluminum plate 4 due to the offset of the positioning block 3.

[0029] Please see Figure 1-4 A hinge plate 323 is fixedly connected to one end of the fixing block 32 near the aluminum plate 4, and a pressure plate 325 is rotatably mounted on the end of the hinge plate 323. The hinge plate 323 can stably transmit the thrust of the fixing block 32 to the pressure plate 325. The rotatable connection allows the pressure plate 325 to flexibly adjust its posture according to the angle of the aluminum plate 4, breaking the limitation of the fixed pressure plate 325 on the angle of the aluminum plate 4 and improving the positioning adaptability. Two sets of pressure plates 325 are provided, and the two sets of pressure plates 325 correspond to the two adjacent right-angled sides of the aluminum plate 4, respectively, avoiding the single pressure plate 325. The positioning offset caused by 25, and the two sets of pressure plates 325 are V-shaped hinged to the end of the hinge plate 323. The end of the fixing block 32 near the hinge plate 323 is fixedly installed with a No. 3 spring 324, and the fixing block 32 and the pressure plate 325 are connected to each other through the No. 3 spring 324. The No. 3 spring 324 can adaptively extend and retract with the rotation of the pressure plate 325, ensuring that the pressure plate 325 is always in close contact with the surface of the aluminum plate 4. Stable positioning of the aluminum plate 4 at different angles can be achieved without manual adjustment, thereby further expanding the application range of the device.

[0030] Please see Figure 1-4The positioning block 3 is sleeved on the outer wall of the fixed block 32, so that the sliding of the fixed block 32 is completely restricted inside the positioning block 3, avoiding lateral displacement or shaking when the fixed block 32 slides, and ensuring that the fixed block 32 always moves stably along the preset trajectory. The top of the positioning block 3 has an opening corresponding to the toggle plate 321, which provides sufficient space for the sliding of the toggle plate 321, and can also limit the movement range of the toggle plate 321 through the edge of the opening, preventing the second spring 322 from exceeding the elastic deformation limit due to excessive sliding of the toggle plate 321, thus extending its service life. Furthermore, the plane at the top of the toggle plate 321 is higher than the plane at the top of the positioning block 3. The extended design of the toggle plate 321 increases the operating contact area, making it convenient for the testing personnel to quickly apply force to drive the fixed block 32 to slide.

[0031] The working principle of this utility model is as follows: The testing personnel first place the tooling plate 2 on the operating table of the main body 1 of the device, align the pins 31 at the bottom of a set of positioning blocks 3 with the positioning holes 21 on the tooling plate 2 and insert them. During the insertion process, the end of the pin 31 first enters the positioning hole 21, and then the bottom inclined surface of the support 311 contacts the top of the positioning hole 21. Since the initial width of the support 311 is greater than the diameter of the positioning hole 21, the opening edge of the positioning hole 21 generates abutment pressure on it. Under the action of pressure, the two sets of support 311 slide inward. When sliding, the support... The guide blocks 314 at the top and bottom of the opening 311 cooperate with the guide groove 313 opened on the inner wall of the pin 31 to limit the sliding trajectory. At this time, the two sets of opening parts 311 change their width to adapt to the diameter of the positioning hole 21 by compressing the No. 1 spring 312 connected in the middle. When the opening part 311 is fully inserted into the positioning hole 21, under the action of the elastic force of the No. 1 spring 312, the opening part 311 will be pushed outward and tightly abut against the inner wall of the positioning hole 21, thereby realizing the firm fixation of the pin 31 inside the positioning hole 21, achieving the effect of quick installation and stable fixation.

[0032] After the pin 31 is installed, the two adjacent right-angled sides of the aluminum plate 4 are placed on the tooling plate 2 with the pressure plate 325 attached. Then, another set of positioning blocks 3 is installed at the diagonal position. At this time, the pressure plates 325 on the two sets of positioning blocks 3 work together to accurately position the aluminum plate 4. The aluminum plate 4 is fixed by the contact pressure between the pressure plate 325 and the surface of the aluminum plate 4, preventing the aluminum plate 4 from shifting during the inspection process. If the angle of the aluminum plate 4 to be inspected is greater than 90 degrees, the pressure plate 325 will rotate around the hinge axis that is hinged to the hinge plate 323. The No. 3 spring 324 provides the adaptation space for the rotation of the pressure plate 325, so that the positioning block 3 can adaptively adjust the angle according to the angle of the aluminum plate 4, improving the versatility of the positioning block 3 for aluminum plates 4 with different angles.

[0033] When replacing another aluminum plate 4, the inspector only needs to move the actuating plate 321 of one of the positioning blocks 3. The actuating plate 321 drives the fixing block 32 to move away from the pressure plate 325. During this process, the actuating plate 321 converts the thrust through the fixing block 32 into pressure on the second spring 322, causing the second spring 322 to compress and deform and store force. At the same time, the hinge plate 323 drives the pressure plate 325 away from the surface of the aluminum plate 4. At this time, the aluminum plate 4 loses the fixing effect of the pressure plate 325. The inspector can remove the aluminum plate 4 from the tooling plate 2, replace it with another aluminum plate 4 of the same specification, and then release the actuating plate 321. The second spring 322 loses pressure and releases elastic potential energy, pushing the fixing block 32 and the hinge plate 323 to reset, thereby causing the pressure plate 325 to once again adhere to the right angle edge of the aluminum plate 4, and re-fix and position it.
