Description

Technical Field

[0001] This application relates to the field of workpiece quality inspection technology, and in particular to a tooling for inspecting the quality of a cover plate bracket. Background Technology

[0002] The cover plate support includes a plate body and inserts at both ends of the plate body. In the production process of the cover plate support, after the plate body is processed, the two inserts are usually manually inserted into the grooves at both ends of the plate body before subsequent processing steps are carried out. Since manual insertion of the inserts may result in errors, it is easy for some plates to have no inserts installed or for the inserts to be not installed securely. Therefore, it is necessary to check the installation of the inserts on the plate body after manual installation.

[0003] Currently, the inspection of the installation status of inserts on the board is usually done manually. After the board is processed and the inserts are embedded, the inspectors carefully observe each workpiece with the naked eye to check for any missing inserts or loose installations. This manual inspection method can ensure the basic quality of the product to a certain extent and is a relatively common and direct inspection method.

[0004] However, the aforementioned manual inspection method has obvious drawbacks. During the long inspection process, inspectors are prone to fatigue and blurred vision, which may lead to frequent missed or incorrect inspections. This results in some workpieces with problems in insert installation flowing into subsequent processing stages, thereby affecting the overall product quality and production efficiency. Utility Model Content

[0005] To address the issue of low accuracy in manual inspection of cover plate bracket quality, this application provides a tooling for inspecting the quality of cover plate brackets.

[0006] This application provides a quality inspection fixture for a cover plate bracket, which adopts the following technical solution:

[0007] A quality inspection fixture for a cover plate bracket includes a base and a mounting frame fixedly connected to the base. The mounting frame is equipped with a detection mechanism for detecting the installation status of inserts on the workpiece. Two detection mechanisms are provided, corresponding to the number and position of inserts on the workpiece. The base is equipped with a control button, a controller, a conveying mechanism, and a feedback mechanism. The conveying mechanism is used to transport the workpiece to the area below the two detection mechanisms for inspection, and the feedback mechanism is used to provide feedback on the inspection results of the two detection mechanisms. The control button is electrically connected to the controller, and the conveying mechanism, detection mechanism, and feedback mechanism are all electrically connected to the controller.

[0008] By adopting the above technical solution, the base and mounting frame provide support and installation foundation for the entire tooling. Two detection mechanisms on the mounting frame are set to correspond to the number and position of the inserts on the workpiece, allowing for simultaneous and accurate detection of the insert installation status at both ends of the workpiece. When the control button is pressed, a start signal is sent to the controller. Upon receiving the start signal, the controller controls the conveyor mechanism to transport the workpiece to below the two detection mechanisms. Subsequently, the controller controls the two detection mechanisms to perform simultaneous detection and transmit the detection results to the controller. After receiving the detection results, the controller controls the feedback mechanism to display the results so that operators can obtain them. The entire process achieves automated detection of the cover plate bracket quality, avoiding omissions and errors in manual detection, improving the accuracy and efficiency of detection, thereby improving the overall product quality and production efficiency.

[0009] Preferably, any of the detection mechanisms includes a drive cylinder, a pressure sensor, and a detection head, wherein the drive cylinder and the pressure sensor are both electrically connected to the controller, the drive cylinder is fixedly connected to the mounting bracket, the pressure sensor is disposed on the piston rod of the drive cylinder, and the detection head is fixedly connected to the pressure sensor.

[0010] By adopting the above technical solution, when the conveying mechanism transports the workpiece to the area below the two detection mechanisms, the controller can control the drive cylinder in the detection mechanism to drive the detection head to contact the insert on the workpiece. At the same time, the pressure sensor in the detection mechanism can transmit the pressure signal received by the detection head to the controller, so that the controller can judge the installation status of the insert based on the pressure signal, thereby realizing the automatic detection of the installation status of the insert on the workpiece, and thus improving the detection efficiency and accuracy.

[0011] Preferably, both sides of the drive cylinder are provided with sleeves fixedly connected to the mounting bracket, and a lifting shaft is slidably arranged inside any of the sleeves. Any of the lifting shafts passes through the mounting bracket, and the sliding direction of any of the lifting shafts is parallel to the movement direction of the piston rod of the drive cylinder. Fixed rods are provided at both ends of the two lifting shafts, and both ends of any of the lifting shafts are fixedly connected to the adjacent fixed rod. The fixed rod near the base is fixedly connected to the piston rod of the drive cylinder, and the pressure sensor is fixedly connected to the fixed rod on the piston rod of the drive cylinder.

[0012] By adopting the above technical solution, the piston rod of the drive cylinder is guided and limited by the sleeves on both sides of the drive cylinder and the lifting shaft that slides inside the sleeves, which can prevent the detection head from deviating during the movement, thereby ensuring the accuracy of the detection results; at the same time, the two lifting shafts are connected together by the fixing rods at both ends of the lifting shaft, which enhances the stability of the entire detection mechanism, ensures that the detection process is carried out smoothly, and thus improves the reliability of the tooling.

[0013] Preferably, the conveying mechanism includes a linear cylinder and a horizontal sliding seat, wherein the linear cylinder is electrically connected to the controller, the slide rail of the linear cylinder is fixedly connected to the machine base, the horizontal sliding seat is fixedly connected to the slider of the linear cylinder, and the horizontal sliding seat is provided with a placement groove for placing workpieces.

[0014] By adopting the above technical solution, when the controller receives the start signal, it can control the linear cylinder in the conveying mechanism to drive the horizontal sliding seat to move, automatically transporting the workpiece placed in the placement slot to the two detection mechanisms for synchronous detection, thereby realizing the automatic conveying of the workpiece, enabling the workpiece to reach the detection position accurately and without error, and improving the workpiece conveying efficiency and detection efficiency.

[0015] Preferably, both sides of the linear cylinder slide rail are provided with guide rails fixedly connected to the machine base, and any one of the guide rails is arranged parallel to the linear cylinder slide rail. A sliding block is slidably arranged on any one of the guide rails, and any one of the sliding blocks is fixedly connected to the bottom of the horizontal sliding seat.

[0016] By adopting the above technical solution, guide rails are set on both sides of the slide rail of the linear cylinder, and sliding blocks are set on the guide rails and connected to the bottom of the horizontal sliding seat. This can assist the linear cylinder in driving the horizontal sliding seat to move stably and further limit the movement trajectory of the horizontal sliding seat, thereby improving the stability of the conveying mechanism in transporting workpieces, and thus improving the detection accuracy and reliability of the cover plate bracket quality inspection tooling.

[0017] Preferably, the feedback mechanism includes an alarm light and a display screen fixedly connected to the base, and both the alarm light and the display screen are electrically connected to the controller.

[0018] By adopting the above technical solution, when the controller receives the test results, it can control the alarm light in the feedback mechanism to intuitively remind the operator of the test status; at the same time, the controller can control the display screen to show detailed test results so that the operator can understand the test status more accurately.

[0019] Preferably, a status indicator light is provided at the location of the control button, and the status indicator light is electrically connected to the controller.

[0020] By adopting the above technical solution, when the controller receives the start signal, it can control the status indicator light to illuminate, thereby intuitively displaying the status of the control button and making it easy for operators to quickly understand the operating status of the tooling.

[0021] Preferably, baffles are fixedly connected to both sides of the mounting frame, and the bottom end of the baffle near the conveying mechanism forms an inlet and outlet for the conveying mechanism to transport workpieces between itself and the machine base.

[0022] By adopting the above technical solution, baffles are set on both sides of the mounting frame to avoid interference from external factors in the detection process, thereby improving the accuracy of the detection. At the same time, the baffles can prevent loosely installed inserts from popping out when the detection mechanism is performing the detection, thereby avoiding injury to the operators or damage to surrounding equipment. Furthermore, the bottom of the baffle near the conveying mechanism forms an inlet and outlet with the machine base, which facilitates the conveying mechanism to transport the workpiece, thereby improving the stability of the detection process.

[0029] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0030] This application discloses a quality inspection fixture for cover plate brackets.

[0031] Reference Figure 1 A quality inspection fixture for a cover plate bracket includes a base 1 and a mounting frame 2 fixedly connected to the base 1 by welding. The mounting frame 2 is provided with a detection mechanism 3 for detecting the installation status of inserts on the workpiece. There are two detection mechanisms 3 corresponding to the number and position of inserts on the workpiece. The base 1 is provided with a control button 4, a controller 5, a conveying mechanism 6, and a feedback mechanism 7. The control button 4 is electrically connected to the controller 5, and the conveying mechanism 6, the detection mechanism 3, and the feedback mechanism 7 are all electrically connected to the controller 5. The conveying mechanism 6 is used to transport the workpiece to the two detection mechanisms 3 for inspection, and the feedback mechanism 7 is used to provide feedback on the inspection results of the two detection mechanisms 3. In this embodiment, the feedback mechanism 7 can transport two workpieces simultaneously, and there are four detection mechanisms 3 on the mounting frame 2 corresponding to the number and position of inserts on the two workpieces.

[0032] In practical use, the base 1 and mounting bracket 2 provide support and installation foundation for the entire tooling. When the operator presses the control button 4, the control button 4 sends a start signal to the controller 5. Then, the controller 5 controls the conveying mechanism 6 to simultaneously transport the two workpieces to the corresponding detection mechanism 3 for inspection. Subsequently, the controller 5 controls the four detection mechanisms 3 to simultaneously inspect the installation status of the inserts at both ends of the two workpieces and transmits the inspection results to the controller 5 in real time. Finally, the controller 5 analyzes and processes the received inspection results and controls the feedback mechanism 7 to display the installation status of the inserts on the two workpieces so that the operator can obtain the inspection results. At the same time, the controller 5 controls the conveying mechanism 6 to return to its original position so that the operator can replace the workpiece and perform inspection again. The whole process realizes automated inspection of the quality of the cover plate bracket, avoiding omissions and errors in manual inspection, improving the accuracy and efficiency of inspection. Furthermore, this embodiment can inspect two workpieces simultaneously, further improving inspection efficiency.

[0033] Reference Figure 1 A status indicator light 41 is provided at the location of the control button 4, and the status indicator light 41 is electrically connected to the controller 5. In actual use, when the controller 5 receives the start signal, it will illuminate the status indicator light 41 until the entire detection process is completed, thereby intuitively displaying the status of the control button 4, making it easy for operators to quickly understand the operating status of the tooling.

[0034] Reference Figure 1The conveying mechanism 6 includes a linear cylinder 61 and a horizontal sliding seat 62. The linear cylinder 61 is electrically connected to the controller 5. The slide rail of the linear cylinder 61 is fixedly connected to the machine base 1 by bolts. The horizontal sliding seat 62 is fixedly connected to the slider of the linear cylinder 61 by bolts. The horizontal sliding seat 62 is provided with a placement groove 81 for placing workpieces. In this embodiment, a positioning member 8 is fixedly connected to the horizontal sliding seat 62 by bolts. Two positioning members 8 are provided along the movement direction of the horizontal sliding seat 62, and each of the two positioning members 8 is provided with a placement groove 81. Guide rails 11 are provided on both sides of the slide rail of the linear cylinder 61 and are fixedly connected to the machine base 1 by welding. Each guide rail 11 is parallel to the slide rail of the linear cylinder 61. A sliding block 111 is embedded in each guide rail 11 and is fixedly connected to the bottom of the horizontal sliding seat 62 by bolts.

[0035] In practical use, when the controller 5 receives the start signal, it controls the linear cylinder 61 in the conveying mechanism 6 to move the horizontal sliding seat 62 and the two positioning parts 8, thereby automatically transporting the workpieces placed by the operator in the two placement slots 81 to the corresponding detection mechanism 3 for synchronous detection, realizing automatic workpiece transport, enabling the workpieces to reach the detection position accurately and reliably, and improving workpiece transport efficiency and detection efficiency. When the controller 5 controls the linear cylinder 61 to move the horizontal sliding seat 62, the two sliding blocks 111 will slide along the horizontal sliding seat 62 on the corresponding guide rail 11, thereby assisting the linear cylinder 61 to drive the horizontal sliding seat 62 to move stably and limiting the movement trajectory of the horizontal sliding seat 62, improving the stability of the conveying mechanism 6 in transporting workpieces, and thus improving the detection accuracy and reliability of the cover plate bracket quality detection fixture.

[0036] Reference Figure 1Each of the detection mechanisms 3 includes a drive cylinder 31, a pressure sensor 32, and a detection head 33. Both the drive cylinder 31 and the pressure sensor 32 are electrically connected to the controller 5. The drive cylinder 31 is bolted to the side of the mounting frame 2 facing away from the base 1, and the piston rod of the drive cylinder 31 passes vertically through the mounting frame 2. The pressure sensor 32 is mounted on the piston rod of the drive cylinder 31, and the detection head 33 is located on the side of the pressure sensor 32 closest to the base 1 and is threadedly connected to the pressure sensor 32. Sleeves 21, bolted to the mounting frame 2, are provided on both sides of the drive cylinder 31. A lifting shaft 211 is slidably disposed inside any of the sleeves 21, and any of the lifting shafts 211 is arranged parallel to the movement direction of the piston rod of the drive cylinder 31 and passes through the mounting bracket 2. Fixed rods 212 are provided at both ends of the two lifting shafts 211, and both ends of any of the lifting shafts 211 are fixedly connected to the adjacent fixed rods 212 by welding. The fixed rod 212 near the base 1 is fixedly connected to the piston rod of the drive cylinder 31 by bolts. In this embodiment, the pressure sensor 32 is located on the side of the fixed rod 212 on the piston rod of the drive cylinder 31 near the base 1 and is fixedly connected to the fixed rod 212 by bolts.

[0037] In practical use, when the conveying mechanism 6 transports two workpieces to the corresponding detection mechanism 3, the controller 5 synchronously controls the drive cylinders 31 in all detection mechanisms 3 to move the corresponding force sensors and detection heads 33, so that the detection heads 33 contact the inserts on the workpieces for detection. At the same time, the pressure sensor 32 in the detection mechanism 3 transmits the pressure signal received by the detection head 33 to the controller 5, so that the controller 5 can judge the installation status of the inserts based on the pressure signal, realize the automatic detection of the installation status of the inserts on the workpieces, and thus improve the detection efficiency and accuracy. When the controller 5 controls the drive cylinder 31 to operate, the fixed bracket fixed on the piston rod of the drive cylinder 31 drives the lifting shafts 211 in the two sleeves 21 to slide synchronously, guide and limit the piston rod of the drive cylinder 31, prevent the pressure sensor 32 and the detection head 33 from deviating during the movement, and thus ensure the accuracy of the detection results. The two fixed rods 212 fix the two ends of the two lifting shafts 211 together, enhance the stability of the entire detection mechanism 3, ensure that the detection process is carried out smoothly, and thus improve the reliability of the tooling.

[0038] Reference Figure 1The feedback mechanism 7 includes an alarm light 71 and a display screen 72 fixedly connected to the base 1. Both the alarm light 71 and the display screen 72 are electrically connected to the controller 5. In this embodiment, the display screen 72 is configured with four detection result display areas corresponding to the number and position of the inserts on the two workpieces. In actual use, when the controller 5 determines that there is a defective product among the two workpieces based on the pressure signal, it will control the alarm light 71 in the feedback mechanism 7 to light up, thereby intuitively reminding the operator of the detection status. At the same time, the controller 5 will control the display screen 72 to display the detection results of the corresponding inserts in the four detection result display areas, so that the operator can more accurately understand the detection status.

[0039] Reference Figure 1 The mounting bracket 2 is bolted to both sides of the horizontal sliding seat 62 with baffles 9. The bottom end of the baffle 9 near the conveying mechanism 6 forms an inlet / outlet between the baffle 9 and the base 1 for the conveying mechanism 6 to transport workpieces. In any embodiment of this application, the baffle 9 is transparent. In actual use, the transparent baffle 9 can not only avoid external factors from interfering with the detection process, but also make it easy for operators to clearly observe the detection process, thereby improving the accuracy of the detection. At the same time, the baffle 9 can prevent loosely installed inserts from popping out under the pressure of the detection head 33 during the detection process, thereby avoiding injury to the operator or damage to surrounding equipment. The bottom end of the baffle 9 near the conveying mechanism 6 forms an inlet / outlet between the baffle 9 and the base 1, which facilitates the conveying mechanism 6 to transport workpieces, thereby improving the stability of the detection process.

[0040] The implementation principle of this application embodiment is as follows: The base 1 and the mounting frame 2 provide support and installation foundation for the entire tooling. When the operator places two workpieces into the placement slots 81 of the two positioning parts 8 on the horizontal sliding seat 62 and presses the control button 4, the control button 4 sends a start signal to the controller 5. At this time, the status indicator 41 lights up to show the tooling operation status. Subsequently, the controller 5 drives the linear cylinder 61 in the conveying mechanism 6 to move the horizontal sliding seat 62. At the same time, the two sliding blocks 111 follow the horizontal sliding seat 62 and slide on the corresponding guide rail 11. The linear cylinder 61 assists the horizontal sliding seat 62 to move stably and limits the movement trajectory of the horizontal sliding seat 62, so that the two workpieces are synchronously and stably transported to the bottom of the four detection mechanisms 3 on the mounting frame 2 for detection.

[0041] Upon reaching the detection position, the controller 5 simultaneously controls the drive cylinders 31 of each detection mechanism 3 to move the pressure sensor 32 and the detection head 33 downwards. At this time, the fixed bracket fixed on the piston rod of the drive cylinder 31 synchronously drives the two lifting shafts 211 to slide within the sleeve 21, guiding and limiting the piston rod of the drive cylinder 31 to prevent the pressure sensor 32 and the detection head 33 from deviating during the movement, so that the detection head 33 accurately contacts the insert on the workpiece for detection. At the same time, the pressure sensor 32 transmits the pressure signal to the controller 5, which judges the installation status of the insert. The mounting bracket 2 is provided with transparent baffles 9 on both sides, which can not only avoid external factors from interfering with the detection process, but also make it easy for the operator to clearly observe the detection process. At the same time, the baffles 9 can prevent the loosely installed insert from popping out under the pressure of the detection head 33, thereby avoiding injury to the operator or damage to the surrounding equipment. The bottom of the baffle 9 near the conveying mechanism 6 forms an inlet and outlet with the machine base 1, which facilitates the conveying mechanism 6 to transport the workpiece.

[0042] After the inspection is completed, if one of the two workpieces is found to be defective, the controller 5 will control the alarm light 71 in the feedback mechanism 7 to illuminate, thus visually reminding the operator of the inspection status. At the same time, the controller 5 controls the display screen 72 to display the inspection results of the corresponding blocks in the four inspection result display areas, so that the operator can more accurately understand the inspection status. Subsequently, the controller 5 controls the conveying mechanism 6 to reset, and the status indicator light 41 turns off, so that the operator can replace the workpiece and perform the inspection again. The entire process realizes the automated inspection of the cover plate bracket quality, avoiding the omissions and errors of manual inspection, improving the accuracy and efficiency of inspection. Furthermore, this embodiment can inspect two workpieces simultaneously, further improving the inspection efficiency.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
