Description

A testing device for producing thin-walled arc-shaped parts

[0001] This application claims priority to Chinese Patent Application No. CN 2023107535800, filed with the Patent Office of China on June 26, 2023, entitled “A Testing Device for the Production of Thin-Walled Curved Parts,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The invention relates to the technical field of thin-walled arc-shaped parts production, in particular to a testing device for thin-walled arc-shaped parts production. Background Art

[0003] Thin-walled arc-shaped structural parts with complex features are typical thin-walled, weakly rigid parts, and are widely used in the aviation and aerospace industries. However, they require high precision. Since thin walls are easily deformed during processing, quality assurance is difficult. During the production process, scratches and other defects are easily generated on the outer surface of arc-shaped parts. These defects can seriously affect the quality and service life of the arc-shaped parts. Patent No. CN201710963334.2 discloses a vision-based arc-shaped part outer surface defect detection system, including a computer, an image storage module, a camera, and an image analysis module; wherein: the camera is arranged above the outer surface of the arc-shaped part, and is used to take pictures of the outer surface of the arc-shaped part and transmit the obtained images to the image storage system; the image storage module is used to store images; the computer is connected to the image storage module, and is used to obtain images from the image storage module and mobilize the image analysis module to work; the image analysis module is installed in the computer and is used to analyze and identify images, including an image preprocessing module, a threshold selection module, an image measurement module, a curvature judgment module, a defect detection module, and a defect recognition module. The present invention realizes automatic detection of defects on the outer surface of arc-shaped parts, reduces labor costs, and greatly improves detection efficiency and quality.

[0004] At present, the existing arc-shaped part outer surface defect detection device still has some shortcomings. For example, the existing arc-shaped part outer surface defect detection device uses a visual system and a camera to shoot the outer surface of the arc-shaped part during use, but only uses the camera to shoot pictures, resulting in the surface of the arc-shaped part can only be detected in the form of a flat image, which easily affects the accuracy of the detection. Moreover, during the detection process of the arc-shaped part, manual loading and unloading is required, which is very inconvenient and affects the efficiency of the arc-shaped part detection.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to provide a testing device for producing thin-walled arc-shaped parts, which solves the problems raised in the background technology.

[0019] The other ends of the first fixed strip and the second fixed strip are connected to the third bearing by screws, and the second rotating cylinder is rotatably connected between the two third bearings. The outer sides of the first rotating cylinder and the second rotating cylinder are both sleeved with conveyor belts.

[0020] In this technical solution, after the inspection is completed, the motor in the placement plate can be used to drive the flip plate to rotate, and the thin-walled arc-shaped parts on the flip plate can be directly flipped into the bottom box of the device. Since a conveyor belt is provided in the bottom box of the device, the thin-walled arc-shaped parts will fall onto the conveyor belt, and the test can be directly completed by conveying the thin-walled arc-shaped parts, eliminating the need to manually pick up the thin-walled arc-shaped parts that have been tested.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1.

The infrared ranging sensor is rotated by the motor to detect the inner wall of the thin-walled arc-shaped part. When the distance to the inner wall is different, it indicates that there is a defect in the roundness of the thin-walled arc-shaped part.

[0028] 4. The present invention uses a flip plate in the placement plate. After the test is completed, the motor in the placement plate can be used to drive the flip plate to rotate, and the thin-walled arc-shaped parts on the flip plate can be directly turned over to the bottom box of the device.

DETAILED DESCRIPTION

[0035] Please refer to Figures 1-4. The present invention provides a technical solution: a testing device for the production of thin-walled arc-shaped parts, including a device bottom box 1, a placement plate 202 for placing thin-walled arc-shaped parts is provided on the top of the device bottom box 1, and also includes: a threaded rod 205, which is threadedly connected to the threaded hole in the placement plate 202; a loading mechanism, which is provided at both ends of the interior of the device bottom box 1, and can simultaneously perform loading tests on multiple thin-walled arc-shaped parts, eliminating manual loading. The testing mechanism includes two placement cylinders 207, the top of the placement cylinder 207 is an open structure, and the two placement cylinders 207 are respectively connected to the two ends of the bottom of the device bottom box 1 by screws, and the bottom end of the placement cylinder 207 is connected to a first electric telescopic cylinder 208 by screws, and the top of the first electric telescopic cylinder 208 is fixedly connected to a first push plate 209, and the tops of both sides of the interior of the device bottom box 1 are screwed to a second electric telescopic cylinder 210, and one side of the second electric telescopic cylinder 210 is fixedly connected to a second push plate 211; A limiting rod 206 passes through one side of the placement plate 202, and the bottom of the limiting rod 206 is connected to the bottom box 1 of the device with screws. The bottom of the threaded rod 205 is fixedly connected to the first motor shaft 204, and the bottom of the first motor shaft 204 is connected to the first motor 203. The first motor 203 is screwed to the bottom box 1 of the device. After multiple thin-walled arc-shaped parts are placed in the placement tube 207, when loading is required, the first electric telescopic cylinder 208 and the first motor 203 can be opened. The first electric telescopic cylinder 208 pushes the thin-walled arc-shaped parts to move upward, and the first motor 203 drives the placement plate 202 to move downward through the threaded rod 205. When a thin-walled arc-shaped part is completely exposed when it moves upward, the second electric telescopic cylinder 210 is opened, and the second electric telescopic cylinder 210 drives the second push plate 211. The second push plate 211 pushes the thin-walled arc-shaped part to the surface of the placement plate 202. After the pushing is completed, the placement plate 202 is moved up again to complete the loading of the thin-walled arc-shaped parts.

[0036] A better way is to set an infrared sensor on one side of the second push plate 211. When a thin-walled arc-shaped part is completely exposed when it moves up, the infrared sensor senses the thin-walled arc-shaped part, and the industrial control computer automatically starts the first motor 203 and the second electric telescopic cylinder 210 to move the placement plate 202 downward and push the second push plate 211 to load the material, thereby realizing the automation of loading the thin-walled arc-shaped parts.

[0037] Please refer to Figure 3. A test mechanism is provided on the top of the bottom box 1 of the device. The test mechanism includes a fixed frame plate 2. The bottom of the fixed frame plate 2 is connected to the bottom box 1 of the device by screws. The middle part of the bottom end of the fixed frame plate 2 is connected to an electric slide rail 218 by screws. The bottom of the electric slide rail 218 is slidably connected to an electric slider 219. The bottom of the electric slider 219 is connected to a third electric telescopic cylinder 220 by screws. The bottom of the third electric telescopic cylinder 220 is connected to a second motor 221 by screws. The bottom of the second motor 221 is connected to a second motor shaft 222. The bottom of one side of the second motor shaft 222 is detachably connected to an infrared measuring device. Distance sensor 223, the position of the electric slider 219 can be adjusted by using the electric slide rail 218, and the second motor shaft 222 is adjusted to align with the center position of the thin-walled arc-shaped part. After alignment, the third electric telescopic cylinder 220 is turned on, and the third electric telescopic cylinder 220 drives the second motor shaft 222 and the infrared distance sensor 223 to move downward. After moving to the center position, the second motor 221 is turned on to make the infrared distance sensor 223 rotate around the thin-walled arc-shaped part, so that the inner wall of the thin-walled arc-shaped part can be detected. When the distance of the inner wall is different, it means that there is a defect in the roundness of the thin-walled arc-shaped part.

[0038] Please refer to Figure 3. 3D cameras 224 are connected to both sides of the bottom of the electric slider 219 by screws. The 3D camera 224 can be used to obtain 3D data of the thin-walled curved part and transmit the 3D data to a computer. By checking the 3D data of the thin-walled curved part on the computer, abnormal 3D data can be observed, thereby discovering whether there are defects on the surface of the thin-walled curved part.

[0039] Referring to Figures 1 and 2 , a placement plate 202 is positioned within a first square hole 201 defined in the top of the device's bottom case 1. A second square hole 225 is defined in the top of the placement plate 202, and a first groove 212 and a second groove 213 are defined on either side of the inner wall of the second square hole 225. Referring to Figure 2 , a first bearing 216 is screwed into the first groove 212. One end of a rotating rod 217 is rotatably connected to the first bearing 216. A flap 226 is fixedly connected to the other end of the rotating rod 217. A motor 214 is screwed into one side of the second groove 213. A motor shaft 215 is connected to one side of the motor 214. The flap 226 is fixedly connected to the side of the motor shaft 215 facing away from the motor 214. After testing of thin-walled curved parts is complete, the motor 214 can be turned on, driving the motor shaft 215, which in turn rotates the flap 226, causing the thin-walled curved parts on the flap 226 to fall into the device's bottom case 1.

[0040] Please refer to Figures 1 and 2. A square groove 104 is opened on the front side of the device bottom box 1, and a first fixed strip 3 and a second fixed strip 305 are respectively provided on both sides of the middle of the square groove 104. Support rods for support are installed at the bottom of the first fixed strip 3 and the second fixed strip 305, and the support rods are detachably connected to the device bottom box 1.

[0041] Referring to Figure 4 , a third motor 301 is screwed to the rear end of one side of the first fixed strip 3. A third motor shaft 302 is connected to one side of the third motor 301. One side of the third motor shaft 302 passes through the first fixed strip 3 and is fixedly connected to the first rotating cylinder 303. A second bearing 304 is rotatably connected to the side of the first rotating cylinder 303 away from the third motor shaft 302. The end of the second bearing 304 away from the first rotating cylinder 303 is screwed to the second fixed strip 305.

[0042] The other ends of the first fixed strip 3 and the second fixed strip 305 are connected to the third bearing 306 by screws, and the second rotating cylinder 307 is rotatably connected between the two third bearings 306. The outer sides of the first rotating cylinder 303 and the second rotating cylinder 307 are both sleeved with conveyor belts 309. After the thin-walled arc-shaped parts enter the bottom box 1 of the device, they will fall onto the surface of the conveyor belt 309. The conveyor belt 309 can be used to transport the thin-walled arc-shaped parts after the test is completed.

[0043] A better way is to set pressure sensors at the bottom of the second bearing 304 and the third bearing 306. Using the pressure sensors, after the thin-walled arc-shaped parts fall onto the conveyor belt 309, the conveyor belt 309 and the bearings are subjected to pressure. The pressure sensors will sense the pressure, and the industrial control computer will automatically start the third motor 301 to complete the automation of the conveying.

[0044] Please refer to Figure 4. Multiple electric heating tubes 308 are equidistantly connected with screws in the middle between the first fixed strip 3 and the second fixed strip 305, and the multiple electric heating tubes 308 all pass through the middle of the conveyor belt 309. The electric heating tubes 308 are arranged between the fixed strips, and the electric heating tubes 308 can be used to heat treat the conveyed thin-walled arc-shaped parts.

[0045] Please refer to FIG1 . Both ends of the front side of the square slot 104 are rotatably connected to hinges 101 . The other end of the hinge 101 is fixedly connected to a baffle 102 . A handle 103 is welded to one end of the front side of the baffle 102 .

[0046] When using a testing device for producing thin-walled arc-shaped parts, a plurality of thin-walled arc-shaped parts are first placed in the placement cylinder 207. After the placement is completed, when loading is required, the first electric telescopic cylinder 208 and the first motor 203 can be turned on. The first electric telescopic cylinder 208 pushes the thin-walled arc-shaped parts upward, and the first motor drives the placement plate 202 to move downward through the threaded rod 205. When the thin-walled arc-shaped parts are completely exposed after the upward movement, the second electric telescopic cylinder 210 is turned on. The second electric telescopic cylinder 210 drives the second push plate 211, and the second push plate 211 pushes the thin-walled arc-shaped parts to the surface of the placement plate 202. After the pushing is completed, the placement plate 202 is moved up to complete the loading of the thin-walled arc-shaped parts. After the loading is completed, the position of the electric slider 219 can be adjusted by using the electric slide rail 218, and the second motor shaft 222 is adjusted to align with the center position of the thin-walled arc-shaped parts. After alignment, the third electric telescopic cylinder 220 is turned on, and the third electric telescopic cylinder 220 drives the second motor 221, the second motor shaft 222 and the infrared ranging sensor 223 to move downward. After moving to the center position of the thin-walled arc-shaped parts, the second motor 221 is turned on to make the infrared ranging sensor 223 rotate around the thin-walled arc-shaped parts, which can accurately measure the thin-walled arc-shaped parts. The inner wall of the curved part is inspected. When the distance between the inner walls is not uniform, it indicates that there is a defect in the roundness of the thin-walled curved part. The 3D camera 224 can obtain the 3D data of the thin-walled curved part and transmit the 3D data to the computer. The 3D data of the thin-walled curved part is viewed by the computer and abnormal 3D data can be observed, thereby finding out whether there is a defect on the surface of the thin-walled curved part. After the thin-walled curved part test is completed, the motor 214 can be turned on, the motor 214 drives the motor shaft 215, and the motor shaft 215 drives the flap 226 to rotate, so that the thin-walled curved part on the flap 226 falls off. It falls into the bottom box 1 of the device. After the thin-walled arc-shaped parts enter the bottom box 1 of the device, they will fall onto the surface of the conveyor belt 309. At this time, the third motor 301 can be turned on, and the third motor 301 drives the third motor shaft 302. The third motor shaft 302 drives the first rotating cylinder 303. The first rotating cylinder 303 drives the conveyor belt 309 and the second rotating cylinder 307. The conveyor belt 309 can be used to convey the thin-walled arc-shaped parts after the test is completed. During the conveying process of the thin-walled arc-shaped parts, the electric heating tube 308 can be turned on, and the electric heating tube 308 can perform heat treatment on the conveyed thin-walled arc-shaped parts.
