Description

Technical Field

[0001] This invention relates to the field of measurement technology in door and window production, specifically to a dimensional measuring device for door and window production. Background Technology

[0002] Doors and windows are classified as enclosure components or partition components according to their location, and have different design requirements, such as heat insulation, sound insulation, waterproofing, and fireproofing. The airtightness of doors and windows is an important aspect of energy-saving design. Doors and windows are important components of the building envelope system, and they are also important components of the building's shape. Therefore, their shape, size, proportion, arrangement, color, and style have a great influence on the overall appearance of the building.

[0003] In the current door panel manufacturing process, the dimensions are mostly measured manually with a measuring tape, and these measurements are usually taken once while the door panel is stationary. Static measurements can only obtain dimensional information of the door panel in a specific state and cannot reflect the deformation that may occur when the door panel is rotated in actual use. During the rotation process, the door panel may undergo slight deformation due to its own weight, external forces, and internal material stress. These deformations cannot be detected during static measurements, thus causing some potential quality problems to be overlooked. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-9This technical solution provides a size measuring device for door and window production, specifically including a base plate 1. A size measuring mechanism 2 is installed on the top of the base plate 1. The size measuring mechanism 2 includes a first slide rail 201, an electric telescopic rod 202, a first bracket 204, and a mounting bracket 207. The first slide rail 201 is slidably installed on the top of the base plate 1. Two first slide rails 201 are provided, and laser rangefinders 230 are slidably installed inside both first slide rails 201. When it is necessary to measure the size of a door, the entire door body is engaged with the side of the first slide rail 201, and then the two first slide rails 201 are moved so that the two first slide rails... 201 can clamp the entire door body. At this time, the laser rangefinder 230 can measure the width of the door frame. Two first slide rails 201 are used to clamp and fix the door frame. The electric telescopic rod 202 is rotatably installed on the top of the base plate 1. The end of the electric telescopic rod 202 is rotatably installed with a pad 203. The electric telescopic rod 202 is used to open and close the door panel. When the electric telescopic rod 202 extends or retracts, it can open and close the door panel to measure the degree of deformation of the door panel. The first bracket 204 is fixedly installed on the top of the base plate 1. The top of the first bracket 204 is detachably installed with an arc plate 205. There are two curved plates 205, each with an internal curved groove 206. The curved plates 205 are used to record the opening and closing degree of the door panel. A mounting bracket 207 is fixedly installed on the top of the first bracket 204. A first sliding groove 208 is provided on the side of the mounting bracket 207, and a sliding plate 209 is slidably installed inside the first sliding groove 208. A first sliding block 210 is slidably installed inside the right curved groove 206, and a first adhesive plate 211 is fixedly installed on the side of the first sliding block 210. Therefore, when the door panel opens and closes, the first adhesive plate 211 moves with the door panel, and the movement of the first adhesive plate 211 drives the sliding plate 209. 09 moves inside the first sliding groove 208. A first rotating rod 212 is rotatably mounted on the other side of the first sliding block 210. A first support 213 is fixedly mounted on the top of the first bracket 204. A first rotating plate 214 is rotatably mounted on the side of the first support 213. A second sliding groove 215 is opened on the surface of the first rotating plate 214. The first rotating rod 212 is slidably connected to the second sliding groove 215. When the first sliding block 210 slides inside the arc groove 206, it can drive the first rotating rod 212 to rotate. When the first rotating rod 212 rotates, it can slide inside the second sliding groove 215.

[0023] Reference Figures 1-9This embodiment also proposes that a partition plate 216 is fixedly installed inside the second slide groove 215, and a first sliding rod 217 is fixedly installed on the side of the first rotating rod 212. The first sliding rod 217 passes through the entire partition plate 216 and is slidably connected to the partition plate 216. A first spring 218 is sleeved on the surface of the first sliding rod 217. The first spring 218 is disposed between the partition plate 216 and the first rotating rod 212. When the first rotating rod 212 slides inside the second slide groove 215, it pushes the first sliding rod 217, thereby compressing the first spring 218. Through the setting of the first rotating plate 214, the first sliding block 210 can slide smoothly inside the arc groove 206, so that the first rotating rod 212 and the first sliding block 210 can slide smoothly inside the arc groove 206. There is an elastic space between 10, allowing the first sliding block 210 to slide smoothly inside the arc-shaped groove 206. If the first rotating rod 212 and the first sliding block 210 are rigidly connected, when the door panel rotates, the deformation of the door panel itself will cause the rotation trajectory to change, affecting the sliding of the first sliding block 210 inside the arc-shaped groove 206. A second rotating rod 219 is rotatably mounted on the side of the first rotating rod 212, and the end of the second rotating rod 219 is rotatably connected to the slide plate 209. A connecting frame 220 is fixedly mounted on the side of the slide plate 209, and a first toothed plate 221 is slidably mounted inside the mounting frame 207. The connecting frame 220 is fixedly connected to the first toothed plate 221. When the first sliding block 210 slides in the arc-shaped groove 206, the first sliding block 210 can slide smoothly inside the arc-shaped groove 206. When the slide inside the groove 206, it will drive the second rotating rod 219 to rotate, thus pushing the slide plate 209 to slide inside the first slide groove 208. The sliding of the slide plate 209 can drive the connecting frame 220 to move, which in turn can drive the first toothed plate 221 to move. The first gear 222 is rotatably mounted on the inner side of the mounting frame 207. The first gear 222 meshes with the first toothed plate 221. The movement of the first toothed plate 221 can drive the first gear 222 to rotate. The first motor 223 is fixedly mounted on the bottom of the base plate 1. The first threaded rod 224 is rotatably mounted on the side of the first bracket 204. The first threaded rod 224 is connected to the output end of the first motor 223 through a pulley set. The surface of the first threaded rod 224 is threaded. A mounting base 225 is connected to the first bracket 204. A support base 226 is rotatably mounted inside the mounting base 225. A micrometer 227 is fixedly mounted to the end of the support base 226. A second slide rod 228 is fixedly mounted to the side of the first bracket 204, and the second slide rod 228 is slidably connected to the mounting base 225. The second slide rod 228 is used to limit the movement of the mounting base 225. A gear 229 is rotatably mounted to the side of the first bracket 204, and the gear 229 is fixedly connected to a first gear 222. The gear 229 is rotatably connected to the mounting base 225. The support base 226 meshes with the gear 229. A first motor 223 can drive a first threaded rod 224 to rotate, thereby moving the mounting base 225. The movement of the mounting base 225 can move the micrometer 227.The micrometer 227 measures the degree of deformation on the door panel surface. When the door panel rotates, the rotating panel drives the first gear 222 to rotate, which in turn drives the rack 229 to rotate. The rotation of the rack 229 drives the support 226 to rotate, thus allowing the micrometer 227 to rotate. This ensures that the micrometer 227 remains perpendicular to the door panel surface. By measuring the degree of deformation, the smooth rotation of the door panel is ensured, avoiding jamming or obstruction caused by deformation. This ensures the normal opening and closing and sealing of the door panel, improving its sound insulation, heat insulation, and waterproof performance. Providing door panels with precise dimensions and deformation within the allowable range makes the installation process smoother, reduces installation errors, ensures installation quality, and provides customers with a good installation experience.

[0024] Reference Figures 1-9This embodiment also proposes that an optical measuring mechanism 3 is installed on the top of the base plate 1. The optical measuring mechanism 3 includes a second bracket 301, which is fixedly installed on the top of the first bracket 204. A second slide rail 302 is provided on the side of the first bracket 204. A horizontal plate 303 is slidably installed inside the second slide rail 302. A laser generator 304 is fixedly installed on the top of the horizontal plate 303. A baffle 305 is fixedly installed on the bottom of the horizontal plate 303. A second sliding block 306 is slidably installed inside the left arc-shaped groove 206. A second adhesive plate 307 is fixedly installed on the side of the second sliding block 306. The second adhesive plate 307 contacts the short side of the door panel. A second rotating plate 308 is rotatably installed on the side of the second sliding block 306. The first bracket 204... A fixing block 309 is fixedly installed at the top, and a second gear 310 is rotatably installed on the side of the fixing block 309. The second gear 310 is fixedly connected to the end of the second rotating plate 308. A second support 311 is fixedly installed at the bottom of the first bracket 204, and a first worm gear 312 is rotatably installed on the side of the second support 311, passing through the entire second support 311. A third gear 313 is fixedly installed at the end of the first worm gear 312, and the third gear 313 meshes with the second gear 310. When the second sliding block 306 moves with the rotation of the door panel, it can drive the second rotating plate 308 to rotate. The center of the second gear 310 is consistent with the rotation center of the second rotating plate 308. Therefore, when the second rotating plate 308 rotates, The first bracket 204 has a third support 314 fixedly mounted at its bottom. A rotating shaft 315 is rotatably mounted inside the third support 314. A first worm gear 316 is fixedly mounted at the end of the rotating shaft 315. The first worm gear 316 meshes with the first worm 312. When the first worm 312 rotates, it drives the first worm gear 316 to rotate, which in turn drives the rotating shaft 315 to rotate. A third bracket 317 is fixedly mounted at its bottom. A second worm gear 318 is rotatably mounted inside the third bracket 317. The worm gear 318 is fixedly connected to the rotating shaft 315. A rotating column 319 is rotatably mounted on the top of the inner cavity of the third bracket 317. A second worm wheel 320 is fixedly mounted on the end of the rotating column 319. The second worm wheel 320 meshes with the second worm gear 318. A mounting plate 321 is fixedly mounted on the bottom of the second worm wheel 320. An eccentric rod 322 is rotatably mounted on the eccentric part of the bottom of the mounting plate 321. A third sliding groove 323 is opened on the top of the base plate 1. A sliding seat 324 is slidably mounted inside the third sliding groove 323. A fixing rod 325 is fixedly mounted on the side of the sliding seat 324. The fixing rod 325 is rotatably connected to the end of the eccentric rod 322. A connecting column 327 is slidably mounted inside the sliding seat 324. A support plate 328 is fixedly mounted on the end of the connecting column 327.A laser receiver 326 is fixedly installed on the top of the support plate 328. A second spring 329 is sleeved on the surface of the connecting column 327. The second spring 329 is located between the support plate 328 and the sliding seat 324. When the rotating shaft 315 rotates, the rotating shaft 315 can drive the second worm gear 318 to rotate, which in turn drives the second worm wheel 320 to rotate. The rotation of the second worm wheel 320 can drive the mounting plate 321 to rotate, which can drive the eccentric rod 322 to rotate eccentrically, which in turn drives the fixed rod 325 to move. This causes the sliding seat 324 to slide back and forth inside the third sliding groove 323, which in turn causes the laser receiver 326 to move back and forth. The laser receiver 326 can receive the laser emitted by the laser generator 304 and transmit it through... The distance between the laser generator 304 and the laser receiver 326 is calculated based on the received time, and this distance is used to measure the length of the door panel. While the door panel rotates, the sliding seat 324 slides back and forth inside the third groove 323, allowing the support plate 328 to repeatedly contact the side of the door panel. When the door panel deforms, the compression of the second spring 329 changes, thus changing the distance between the support plate 328 and the sliding seat 324. Therefore, the change in the door panel's length under deformation can be obtained. By measuring the reciprocating motion of the door panel during rotation, the change in the door panel's length can be dynamically monitored. Even minor deformations or twists can be detected promptly, helping to identify problems early in the production process and avoid producing products with non-compliant dimensions.

[0025] Specifically, the working process or principle of this size measuring device for door and window production is as follows: When it is necessary to measure the size of a door, the entire door body is engaged with the side of the first slide rail 201. Then, the two first slide rails 201 are moved so that they can clamp the entire door body. At this time, the laser rangefinder 230 can measure the width of the door frame. When the electric telescopic rod 202 extends or retracts, the door panel can be opened and closed to measure the degree of deformation of the door panel. Therefore, when the door panel opens and closes, the first plate 211 will move with the opening and closing of the door panel. The movement of the first plate 211 will drive the slide plate 209 in the... The first sliding block 210 moves within the arc-shaped groove 206. When the first sliding block 210 slides within the arc-shaped groove 206, it drives the first rotating rod 212 to rotate. When the first rotating rod 212 rotates, it slides within the second sliding groove 215. When the first rotating rod 212 slides within the second sliding groove 215, it pushes the first sliding rod 217, thereby compressing the first spring 218. The arrangement of the first rotating plate 214 allows the first sliding block 210 to slide smoothly within the arc-shaped groove 206, creating an elastic space between the first rotating rod 212 and the first sliding block 210, allowing... The first sliding block 210 can slide smoothly inside the arc-shaped groove 206. If the first rotating rod 212 and the first sliding block 210 are rigidly connected, when the door panel rotates, the deformation of the door panel itself will cause the rotation trajectory to change, affecting the sliding of the first sliding block 210 inside the arc-shaped groove 206. When the first sliding block 210 slides inside the arc-shaped groove 206, it will drive the second rotating rod 219 to rotate, thus pushing the slide plate 209 to slide inside the first slide groove 208. The sliding of the slide plate 209 can drive the connecting frame 220 to move, which in turn can drive the first toothed plate 221 to move. The movement of the first toothed plate 221 drives the first gear 222 to rotate, which in turn drives the first threaded rod 224 to rotate, thereby moving the mounting base 225. The movement of the mounting base 225 then moves the micrometer 227, which measures the degree of deformation on the door panel surface. When the door panel rotates, the rotating door panel drives the first gear 222 to rotate, which in turn drives the rack 229 to rotate. The rotation of the rack 229 then drives the support base 226 to rotate, thus allowing the micrometer 227 to rotate and remain perpendicular to the door panel surface. This allows for the measurement of the degree of deformation of the door panel.

[0026] When the second sliding block 306 moves with the rotation of the door panel, it can drive the second rotating plate 308 to rotate. The center of the second gear 310 is consistent with the rotation center of the second rotating plate 308. Therefore, when the second rotating plate 308 rotates, it can drive the second gear 310 to rotate. The rotation of the second gear 310 can drive the third gear 313 to rotate. The rotation of the third gear 313 can drive the first worm gear 312 to rotate. When the first worm gear 312 rotates, it can drive the first worm... The wheel 316 rotates, which in turn drives the rotating shaft 315 to rotate. A connecting column 327 is slidably mounted inside the sliding seat 324. A support plate 328 is fixedly mounted at the end of the connecting column 327, and a laser receiver 326 is fixedly mounted on the top of the support plate 328. A second spring 329 is sleeved on the surface of the connecting column 327, and the second spring 329 is positioned between the support plate 328 and the sliding seat 324. When the rotating shaft 315 rotates, it drives the second worm gear 318 to rotate, thereby… The second worm gear 320 can be driven to rotate, which in turn drives the mounting plate 321 to rotate. The rotation of the mounting plate 321 drives the eccentric rod 322 to rotate eccentrically, which in turn drives the fixed rod 325 to move. This causes the sliding seat 324 to slide back and forth inside the third slide groove 323, which in turn drives the laser receiver 326 to move back and forth. The laser receiver 326 can receive the laser emitted by the laser generator 304. By calculating the time of reception, the distance between the laser generator 304 and the laser receiver 326 can be calculated, thereby measuring the length of the door panel. While the door panel is rotating, the sliding seat 324 will slide back and forth inside the third slide groove 323, so that the support plate 328 can reciprocate to contact the side of the door panel. When the door panel deforms, the compression of the second spring 329 will change, so the distance between the support plate 328 and the sliding seat 324 will also change. Therefore, the change data of the length of the door panel under deformation can be obtained.
