Description

Technical Field

[0001] This application relates to the field of automotive parts testing technology, and in particular to an internal hole testing device for automotive parts. Background Technology

[0002] In automotive parts manufacturing, the internal wall inspection of long-hole workpieces is a crucial step in ensuring product quality and performance. This inspection process aims to check for defects and obvious burrs inside the long-hole workpieces, thereby ensuring the fitting and rotational accuracy between parts.

[0003] In the existing technology, the commonly used inspection method is to use tools such as optical magnifying glasses to observe the inner surface of the hole and keyway to check for surface defects such as scratches, burrs, residual material, and cracks. At the same time, an endoscope can also be inserted into the workpiece for inspection.

[0004] However, in actual use, both using an optical magnifying glass and inserting an endoscope rely heavily on manual operation, which may lead to unstable test results and an inability to accurately capture minute defects, resulting in low efficiency. Therefore, this application provides an internal hole inspection device for automotive parts. Utility Model Content

[0005] The purpose of this application is to provide an internal hole inspection device for automotive parts, which addresses the problem that both using optical magnifying glasses and inserting endoscopes rely heavily on manual operation, which may lead to unstable inspection results, inaccurate capture of minute defects, and low efficiency.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An internal bore inspection device for automotive parts includes a worktable, a fixed frame fixedly connected to the worktable, a display screen fixedly connected to one side of the fixed frame, a fixed block fixedly connected to the top of the worktable, a support plate fixedly connected to the top of the fixed block, a vision probe mounted on the top of the support plate, and a connecting block fixedly connected to the top of the fixed block. A movable block is slidably connected to the top of the connecting block, and two movable plates are symmetrically slidably connected to the top of the movable block. A support frame is fixedly connected to the top of the two movable plates, a clamping assembly is installed within the support frame, and a workpiece to be inspected is placed on the top of the support frame. A movable assembly is installed within the connecting block, and a control panel is fixedly connected to the top of the worktable.

[0008] By adopting the above technical solution, the workpiece to be inspected is first removed and placed on top of two support frames. At this time, the position of the workpiece can be limited and fixed by operating the clamping assembly, thereby avoiding inspection errors caused by movement or shaking of the workpiece during the inspection process, thus improving the accuracy and precision of the inspection. Then, the moving assembly is started to move the workpiece on top closer to the vision probe until the inspection end of the vision probe is inserted into the workpiece. At this time, the image is uploaded to the display screen through real-time detection by the vision probe to perform inner wall inspection and check for obvious burrs. This effectively improves the inspection efficiency, realizes fully automated inspection, eliminates the need for manual operation, makes the inspection results more stable, and greatly improves the inspection efficiency.

[0009] Furthermore, a T-shaped block is fixedly connected to the top of one of the movable plates, the top of the T-shaped block being arc-shaped, and one end of the vision probe is placed in the arc-shaped groove.

[0010] By adopting the above technical solution, the detection end of the vision probe is placed in the arc groove of the T-block to maintain the balance of the vision probe, so that the vision probe is directly facing the center through hole of the workpiece being inspected.

[0011] Furthermore, a groove is provided on the top of the movable block, and sliders are fixedly connected to the bottom of both movable plates, with the sliders slidably connected within the grooves.

[0013] Furthermore, the clamping assembly includes a groove formed on the top of the support frame, a bidirectional lead screw rotatably connected through the groove, a knob fixedly connected to one end of the bidirectional lead screw, and two lead screw sleeves symmetrically threaded onto the bidirectional lead screw, with clamping plates fixedly connected to the top of each of the two lead screw sleeves.

[0014] By adopting the above technical solution, the workpiece can be stably positioned on the top of the support frame by clamping with two clamping plates, and the position of the workpiece can be limited and fixed, thereby avoiding detection errors caused by the workpiece moving or shaking during the detection process.

[0015] Furthermore, both of the lead screw sleeves are slidably connected inside the groove.

[0016] By adopting the above technical solution, when the bidirectional lead screw rotates, it will drive the two lead screw sleeves to gradually approach each other inside the groove.

[0017] Furthermore, a rubber pad is fixedly connected to one side of the clamping plate.

[0018] By adopting the above technical solution, the rubber pad can improve the buffering force between the clamping plate and the workpiece being inspected, and avoid damage to the workpiece being inspected due to excessive clamping.

[0019] Furthermore, the moving component includes U-shaped blocks fixedly connected to both sides of the moving block. A guide groove is provided through the interior of the connecting block. The U-shaped blocks are slidably connected inside the guide groove. A screw is rotatably connected through the guide groove. A motor is fixedly connected to one end of the connecting block. The output end of the motor is fixedly connected to one end of the screw. The U-shaped blocks are threadedly connected to the screw.

[0020] By adopting the above technical solution, the movement speed of the workpiece can be adjusted by controlling the motor through the control panel during the inspection process. When the vision probe moves to the center hole inside the workpiece, it can pause briefly for a few seconds, allowing workers to easily observe the condition of the inner wall of the workpiece on the display screen and check for any obvious burrs, thereby effectively improving inspection efficiency.

[0021] Furthermore, a guide rod is fixedly connected inside the guide groove. The U-shaped block is slidably connected to the guide rod.

[0022] By adopting the above technical solution, when the screw rotates, it will drive the U-shaped block to move inside the guide groove according to the guidance of the guide rod.

[0024] 1. This application includes a display screen, a vision probe, a support frame, and a moving component. By activating the moving component, the workpiece at the top is moved closer to the vision probe until the detection end of the vision probe is inserted into the workpiece. At this point, the vision probe uploads the image to the display screen in real time to inspect the inner wall for any obvious burrs. This effectively improves inspection efficiency, achieves fully automated inspection, eliminates the need for manual operation, and makes the inspection results more stable, greatly improving inspection efficiency.

A movable block 7 is slidably connected to the top of the connecting block 6. Two movable plates 8 are symmetrically slidably connected to the top of the movable block 7. A support frame 10 is fixedly connected to the top of the two movable plates 8. A clamping assembly 11 is installed inside the support frame 10. A workpiece 12 is installed on the top of the support frame 10. A movable assembly 13 is installed inside the connecting block 6. A control panel 14 is fixedly connected to the top of the worktable 1. A T-shaped block 9 is fixedly connected to the top of one of the movable plates 8. The top of the T-shaped block 9 is arc-shaped. One end of the vision probe 5 is placed in the arc-shaped groove. A sliding groove 71 is opened on the top of the movable block 7. A slider 81 is fixedly connected to the bottom of both movable plates 8. The slider 81 is slidably connected in the sliding groove 71. All electrical components in the device are electrically connected to the control panel 14.

[0035] In use, firstly, pull the two movable plates 8 to move the support frame 10 on the movable block 7. Through the cooperation of the sliding groove 71 and the slider 81, the distance between the two movable plates 8 can be adjusted according to the length of the workpiece 12. Then, take out the workpiece 12 and place it on top of the two support frames 10. At this time, the position of the workpiece 12 can be limited and fixed by operating the clamping assembly 11, so as to avoid detection errors caused by the movement or shaking of the workpiece 12 during the detection process, thereby improving the accuracy and precision of the detection. After the position of the workpiece 12 is fixed, the vision probe 5 can be taken out and installed on the top of the support plate 4, and the detection end of the vision probe 5 is placed in the arc groove of the T-block 9 to maintain the balance of the vision probe 5, so that the vision probe 5 is directly facing the center through hole of the workpiece 12. After the vision probe 5 is installed, The moving component 13 can be activated to drive the moving block 7 to move on top of the connecting block 6, thereby moving the top inspection workpiece 12 closer to the vision probe 5 until the inspection end of the vision probe 5 is inserted into the inspection workpiece 12. At this time, the image is uploaded to the display screen 21 through the real-time detection of the vision probe 5 for internal wall inspection. During the inspection process, the moving component 13 can be controlled by the control panel 14 to adjust the moving speed of the inspection workpiece 12. When the vision probe 5 moves to the center hole inside the inspection workpiece 12, it can pause briefly for a few seconds, which allows the worker to observe the condition of the inner wall of the inspection workpiece 12 through the display screen 21 to check for any obvious burrs. This effectively improves the inspection efficiency, realizes fully automated inspection, eliminates the need for manual operation, makes the inspection results more stable, and greatly improves the inspection efficiency.

[0036] Reference Figure 1 and Figure 3 The clamping assembly 11 includes a groove 110 formed on the top of the support frame 10. A bidirectional lead screw 111 is rotatably connected through the groove 110. A knob 112 is fixedly connected to one end of the bidirectional lead screw 111. Two lead screw sleeves 113 are symmetrically threaded onto the bidirectional lead screw 111. A clamping plate 114 is fixedly connected to the top of each of the two lead screw sleeves 113. Both lead screw sleeves 113 are slidably connected inside the groove 110. A rubber pad 115 is fixedly connected to one side of the clamping plate 114.

[0037] In use, first turn the knob 112 to drive the bidirectional lead screw 111 to rotate. When the bidirectional lead screw 111 rotates, it will drive the two lead screw sleeves 113 to gradually approach each other inside the groove 110, thereby driving the two clamping plates 114 to approach together until the two clamping plates 114 are tightly clamped to the outer wall of the workpiece 12. Through the clamping of the two clamping plates 114, the workpiece 12 can be stably placed on the top of the support frame 10, and the position of the workpiece 12 is limited and fixed, thereby avoiding detection errors caused by the movement or shaking of the workpiece 12 during the detection process, thus improving the accuracy and precision of the detection.

[0038] Reference Figure 1 and Figure 4 The moving component 13 includes U-shaped blocks 131 fixedly connected to both sides of the moving block 7. A guide groove 132 is provided through the interior of the connecting block 6. The U-shaped blocks 131 are slidably connected inside the guide groove 132. A screw 133 is rotatably connected through the guide groove 132. A motor 134 is fixedly connected to one end of the connecting block 6. The output end of the motor 134 is fixedly connected to one end of the screw 133. The U-shaped blocks 131 are threadedly connected to the screw 133. A guide rod 135 is fixedly connected inside the guide groove 132. The U-shaped blocks 131 are slidably connected to the guide rod 135.

[0039] In use, the motor 134 is first started to drive the screw 133 to rotate. When the screw 133 rotates, it will drive the U-shaped block 131 to move inside the guide groove 132 according to the guide rod 135. In this way, the U-shaped block 131 drives the moving block 7 to move on the connecting block 6. During the inspection process, the moving speed of the workpiece 12 can be adjusted by controlling the motor 134 through the control panel 14. When the vision probe 5 moves to the center hole inside the workpiece 12, it can pause briefly for a few seconds, which allows the worker to observe the condition of the inner wall of the workpiece 12 through the display screen 21 and check for any obvious burrs, thereby effectively improving the inspection efficiency.

[0040] The implementation principle of the internal hole detection device for automotive parts in this embodiment is as follows: In use, firstly, the two moving plates 8 are pulled to move the support frame 10 on the moving block 7. Through the cooperation of the sliding groove 71 and the slider 81, the distance between the two moving plates 8 can be adjusted according to the length of the workpiece 12 to be detected. Then, the workpiece 12 to be detected is taken out and placed on the top of the two support frames 10. At this time, the double-acting screw 111 can be rotated by turning the knob 112. When the double-acting screw 111 rotates, it will drive the two screw sleeves 113 to gradually approach each other inside the groove 110, thereby driving the two clamping plates 114 to approach each other until the two clamping plates 114 are tightly clamped to the outer wall of the workpiece 12. Through the clamping of the two clamping plates 114, the workpiece 12 to be detected can be stably placed on the top of the support frame 10. The position of the workpiece 12 is limited and fixed, thereby avoiding detection errors caused by the movement or shaking of the workpiece 12 during the detection process, thereby improving the accuracy and precision of the detection.

[0041] Once the position of the workpiece 12 is fixed, the vision probe 5 can be removed and installed on the top of the support plate 4. The detection end of the vision probe 5 is placed in the arc groove of the T-block 9 to maintain the balance of the vision probe 5, so that the vision probe 5 is directly facing the center through hole of the workpiece 12. After the vision probe 5 is installed, the motor 134 can be started to drive the screw 133 to rotate. When the screw 133 rotates, it will drive the U-block 131 to move inside the guide groove 132 according to the guide rod 135. In this way, the U-block 131 drives the moving block 7 to move on the connecting block 6, thereby moving the top workpiece 12 closer to the vision probe 5 until the vision probe is in place. The detection end of the probe 5 is inserted into the workpiece 12. At this time, the image is uploaded to the display screen 21 through real-time detection by the vision probe 5 to perform inner wall inspection. During the inspection process, the moving speed of the workpiece 12 can be adjusted by controlling the motor 134 through the control panel 14. When the vision probe 5 moves to the center hole inside the workpiece 12, it can pause briefly for a few seconds, which allows the worker to observe the condition of the inner wall of the workpiece 12 through the display screen 21 and check for any obvious burrs. This effectively improves the inspection efficiency, realizes fully automated inspection, eliminates the need for manual operation, makes the inspection results more stable, and greatly improves the inspection efficiency.
