Description

Technical Field

[0001] This utility model belongs to the field of product hole quality inspection devices, specifically relating to a product hole contour and diameter detection device. Background Technology

[0002] During the die casting production process, it is necessary to inspect the holes on the die castings. The conventional operation is for quality inspectors to use plug gauges, feeler gauges and other inspection tools to check whether the diameter of the holes meets the standards. Since there are many holes on die castings and they are distributed in different locations, and given that die castings are generally heavy, these issues can hinder the quality inspection work and lead to low quality inspection efficiency. Moreover, due to the varying skill levels and experience of the quality inspectors, it is very easy for incorrect inspections and omissions to occur. Secondly, certain channels on die-cast parts have very high requirements for their contours, making it difficult for quality inspectors to determine their quality by visual inspection. Dimensional measurement is time-consuming, complex, and prone to errors. Furthermore, traditional manual quality inspection is gradually being phased out, and production technologies across all industries are transitioning towards full automation. Therefore, to address the problems encountered by enterprises in the aforementioned production processes, relevant technical personnel need to develop efficient and highly accurate automated quality inspection devices to solve these technical issues.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Please refer to Figure 1-7 As shown, an embodiment of this application provides a product hole contour and hole diameter detection device, including a workbench 1, a safety cover 2 on the top of the workbench 1, two sets of linear servo modules 4 arranged side by side on the top of the workbench 1, a positioning clamping fixture 3 on the sliding end of the top of the linear servo module 4, and a hole contour detection device 5 arranged on the top of the workbench 1 and in the middle behind the two sets of linear servo modules 4. Both the two sets of positioning clamping fixtures 3 and the hole contour detection device 5 are inside the safety cover 2. The positioning and clamping fixture 3 includes an aluminum mounting plate 31. A quick-clamping mechanism 32 is provided on the top of the aluminum mounting plate 31 and near each of its four corners. The tops of the four quick-clamping mechanisms 32 clamp and fix the workpiece 6 to be inspected. The surface of the workpiece 6 has multiple inspection holes 61, including vertical holes and inclined holes. A lifting platform mechanism 33 is provided on the top of the aluminum mounting plate 31 and at the center of the four quick-clamping mechanisms 32. A hole diameter detection component 35 is provided on the top of the lifting platform mechanism 33 corresponding to each vertical hole, and a secondary cylinder 36 is provided corresponding to each inclined hole. The extension end of the secondary cylinder 36 is also equipped with a hole diameter detection component 35 to detect the diameter of the inclined holes. A retractable supplementary lighting device 34 is provided on the top of the lifting platform mechanism 33 corresponding to some of the inspection holes 61. The hole contour detection device 5 uses the supplementary lighting device 34 to provide light to take clear photos of the contours of the corresponding inspection holes 61 and transmits them to the industrial control computer.

[0018] Specific examples Figure 1-3 As shown, the operator manually places the workpiece 6 to be inspected into the positioning and clamping fixture 3. The four positioning surfaces of the workpiece 6 are placed on top of the four quick-clamping mechanisms 32, and the industrial control computer controls each quick-clamping mechanism 32 to clamp and fix the workpiece 6. Then, the lifting platform mechanism 33 carries all the hole diameter detection components 35 to lift it from the bottom and approach the workpiece 6. The vertically set hole diameter detection components 35 detect a portion of the vertical holes in the holes 61 to be inspected. After the vertical holes are detected, each inclined hole is detected by each secondary cylinder 36 lifting the hole diameter detection components 35 on it. The industrial control computer determines whether each hole diameter is qualified. After all the holes 61 to be inspected have been inspected, the positioning and clamping fixture 3 carrying the workpiece 6 to be inspected is moved to the hole contour detection device 5 by the linear servo module 4. At the same time, the supplementary lighting device 34 is moved to the hole 61 to be inspected that needs supplementary lighting to enhance the light intensity by the industrial control computer. The contour of the hole 61 to be inspected is then detected by the hole contour detection device 5, and the industrial control computer determines whether the contour is qualified. After all the inspections are completed, the workpiece is unloaded manually. This product's hole contour and diameter detection device allows for manual loading and unloading, while being fully automated and programmed by an industrial control computer. Two sets of linear servo modules 4 are arranged side-by-side along the length of the worktable 1, with the hole contour detection device 5 positioned at the rear center of the two linear servo modules 4, forming a 'front clamping, rear detection' layout. Two sets of positioning clamping fixtures 3 alternately load and unload, further improving the device's detection efficiency. Simultaneously, each hole diameter detection component 35 corresponds one-to-one with the diameter of each hole 61 to be inspected, and the supplementary lighting device 34, in conjunction with the hole contour detection device 5, detects a specified portion of the hole contour of the workpiece 6. This allows for precise identification and rejection of workpieces with substandard hole diameters and contours, significantly improving product quality inspection efficiency and accuracy, and effectively ensuring the quality of the products leaving the factory.

[0019] In a preferred embodiment of this utility model, the positioning clamping fixture 3 further includes a load-bearing column 324, which is fixedly installed on the top surface of the mounting aluminum plate 31 by bolts. A quick-clamping cylinder 322 is fixedly installed on one side of the top surface of the load-bearing column 324, and a reaction column 323 is fixedly installed on the other side. The end of the telescopic shaft of the quick-clamping cylinder 322 is hinged to the tail end of the quick-clamping head 321. The middle part of the quick-clamping head 321 is hinged to the top of the cylinder body of the quick-clamping cylinder 322 through the frame. Its front end presses down on the workpiece 6 to be inspected and clamps the workpiece 6 to be inspected together with the top surface of the reaction column 323.

[0020] Specifically, such as Figure 4 As shown, the quick-clamp cylinder 322 is extended and retracted by the industrial control computer, thereby driving the tail of the quick-clamp head 321 to rotate around the central support as the origin, thereby controlling the gap between the front end of the quick-clamp head 321 and the top surface of the reaction column 323, thus realizing the function of clamping the workpiece 6 to be inspected by cooperating with the top surface of the reaction column 323 and the front end of the quick-clamp head 321.

[0021] In a preferred embodiment of this utility model, the lifting platform mechanism 33 further includes four guide rods 332, all of which are fixedly installed on the top of the mounting aluminum plate 31 by bolts. A lifting plate 331 is slidably connected between the four guide rods 332 in the vertical direction. The center of the bottom of the lifting plate 331 is fixedly installed to the top of the telescopic shaft of the lifting cylinder 333. The bottom of the cylinder body of the lifting cylinder 333 is fixedly installed on the top surface of the mounting aluminum plate 31.

[0022] In a preferred embodiment of this utility model, the aperture detection component 35 further includes a detection pin 351, which is slidably connected to the lifting plate 331 in the vertical direction. A buffer spring 353 is sleeved on the outside of the detection pin 351. A limiting ring 352 is fixedly installed near the top of the detection pin 351. The two ends of the buffer spring 353 are fixedly connected to the limiting ring 352 and the lifting plate 331, respectively. A proximity ring 355 is fixedly installed near the bottom of the detection pin 351 through the bottom surface of the lifting plate 331. A proximity sensor 354 is provided on one side of the proximity ring 355. The proximity sensor 354 is fixedly installed at the bottom of the lifting plate 331. When the workpiece 6 to be inspected presses down on the detection pin 351, it causes the proximity ring 355 to move away from the proximity sensor 354. The central axis of the detection pin 351 coincides with the central axis of the vertical hole.

[0023] In a preferred embodiment of the present invention, the telescopic shaft of the secondary cylinder 36 is further in an inverted L-shaped structure, the aperture detection component 35 is vertically arranged on the lateral side of the telescopic shaft of the secondary cylinder 36, the central axis of the detection pin 351 coincides with the central axis of the inclined hole, the cylinder body of the secondary cylinder 36 is fixedly installed with the lifting plate 331, and the proximity sensor 354 is fixedly installed on the lateral side of the telescopic shaft of the secondary cylinder 36.

[0024] Specifically, such as Figure 5 As shown, the lifting plate 331 is driven to move vertically up and down by the lifting cylinder 333, which drives the various aperture detection components 35 to move closer to or away from the workpiece 6 to be inspected, thereby completing the actions required by the detection process. The detection pin 351, which detects the aperture, extends into the hole 61 to be inspected from the bottom. When the aperture of the hole is not up to standard, it will interfere with the detection pin 351, thereby pressing down the detection pin 351 and causing the proximity convex ring 355 at the bottom of the detection pin 351 to be displaced. This displacement is then detected by the proximity sensor 354, which determines that the aperture of the hole 61 to be inspected is not up to standard. The diameter of vertical and inclined holes is detected using the above principle. In actual operation, the vertical hole is first detected by the vertically set hole diameter detection component 35, and then the inclined hole is detected by the hole diameter detection component 35 driven by the secondary cylinder 36. All the holes 61 to be inspected are inspected in two steps. After the inspection is completed, the lifting plate 331 is lowered and the detection pin 351 is reset by the reaction force of the reset spring.

[0025] In a preferred embodiment of this utility model, the supplementary lighting device 34 further includes a support bracket 343, which is fixedly installed on the top surface of the mounting aluminum plate 31. A supplementary lighting cylinder 341 is fixedly installed on the top of the support bracket 343, and a supplementary lighting plate 342 is fixedly installed on the telescopic end of the supplementary lighting cylinder 341. The supplementary lighting plate 342 is driven by the supplementary lighting cylinder 341 to move to below the inspection hole 61 that needs supplementary lighting.

[0026] In a preferred embodiment of the present invention, the hole contour detection device 5 further includes a detection robot 51, the movable end of the detection robot 51 is fixedly mounted with a servo slide 53, and the sliding end of the servo slide 53 is provided with two sets of cameras 52 arranged side by side at intervals.

[0027] Specifically, such as Figure 3 , 6 As shown, since the position of the supplementary lighting device 34 extending from the supplementary lighting plate 342 and the position of the aperture detection component 35 on the telescopic shaft of the secondary cylinder 36 will cause spatial interference, the supplementary lighting device 34 is equipped with a supplementary lighting cylinder 341 that retracts the supplementary lighting plate 342 during the process of detecting the aperture of the hole 61 to be inspected, thereby making room for the detection pin 351 to rise and thus avoiding this positional interference. After the aperture detection is completed, the supplementary lighting cylinder 341 extends to insert the supplementary lighting plate 342 into the corresponding hole 61 to be inspected for supplementary lighting. The posture of each supplementary lighting plate 342 matches the tilted hole. Through this design, while ensuring the normal operation of the overall function process of the device, the interference problem between structures is solved, ensuring the smooth operation of the device. Furthermore, while the supplementary lighting board 342 provides additional illumination, the inspection robot 51, carrying two sets of cameras 52, flips over the workpiece 6 to take pictures of the hole 61 to be inspected and transmits the image information to the industrial control computer for analysis, thereby determining whether the outline of the hole 61 meets the requirements. Through the multi-axis linkage of the inspection robot 51 and the cooperation of the servo slide 53, the two sets of cameras 52 can ensure that the hole outline captured is always a front-projected image, thereby effectively improving the quality inspection accuracy and correctness of this device.

[0028] In a preferred embodiment of the present invention, the working surface of the safety cover 2 is provided with a display 23 and a control panel 24, an alarm light 21 is provided at one corner of its top, and an inspection port is provided on one side of its side, where a safety light curtain 22 is provided.

[0029] Specifically, such as Figure 1 As shown, the industrial control computer is integrated into the safety enclosure 2 or near the equipment. A display 23 on the surface of the safety enclosure 2 enables human-machine interaction. The control panel 24 allows for program switching and control of individual actions of each step and device, facilitating operator control of the equipment for production activities. An alarm light 21 on the top of the safety enclosure 2 provides alarm alerts. An open inspection port on one side of the safety enclosure 2 facilitates operator inspection and maintenance. To ensure operator safety when entering the inspection port, a safety light curtain 22 is installed to prevent accidental entry. The safety light curtain 22 is electrically connected to the industrial control computer. When personnel are detected entering the inspection port, an automatic shutdown protection is triggered, and the alarm light 21 illuminates, improving the overall safety performance of the equipment.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
