Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a high-precision rolling aluminum profile dimensional detection and correction device. Background Technology

[0002] Aluminum profiles refer to profiles made of aluminum and aluminum alloys through processes such as extrusion and rolling, which are processed into profiles with specific shapes and dimensions.

[0003] During the production of rolled aluminum profiles, the dimensions of the aluminum profiles may deviate due to various factors such as raw material characteristics, processing technology, and equipment precision. Traditional dimensional inspection methods mostly rely on manual measurement, which is not only inefficient but also highly susceptible to human error, making it difficult to meet the requirements of high-precision production. At the same time, existing correction devices for detected dimensional deviations are often complex in structure, inconvenient to operate, and have low correction accuracy, failing to achieve rapid and accurate correction, resulting in a high product defect rate and increased production costs. Therefore, we propose a high-precision dimensional inspection and correction device for rolled aluminum profiles. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision device for detecting and correcting the dimensions of rolled aluminum profiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision rolling aluminum profile dimensional detection and correction device includes a structural frame, a traction mechanism at the end of the structural frame, a correction mechanism and a measuring mechanism inside the structural frame; the measuring mechanism includes a fixed frame, two photosensitive screens are fixedly installed inside the fixed frame, structural grooves are provided on corresponding sides of the two photosensitive screens, the structural grooves are fixedly installed inside the fixed frame, infrared irradiation lamps are fixedly installed inside the structural grooves, a protective transparent cover is fixedly installed at the port of the structural groove, and a protective film is applied to the surface of the photosensitive screen.

[0007] Furthermore, the correction mechanism includes four sets of hydraulic rods, which are respectively fixedly installed on the inner wall of the structural frame, and a folding plate is fixedly installed on the output end of each hydraulic rod.

[0008] Furthermore, a stiffening plate is fixedly connected between the side of the folding plate and the side wall of the hydraulic rod output end.

[0009] Furthermore, a controller is fixedly installed on the outer wall of the structural frame.

[0010] Furthermore, the fixed frame is fixedly installed on the inner wall of the structural frame base.

[0011] Furthermore, an aluminum profile is inserted inside the structural frame, and the aluminum profile passes between the inner sides of the four sets of folding plates.

[0012] Furthermore, the traction mechanism includes a structural base, on which clamping grooves are symmetrically fixedly installed. A hydraulic push rod is fixedly installed on the clamping groove. The output end of the hydraulic push rod passes through to the inside of the clamping groove, and a clamping plate is fixedly installed on the output end of the hydraulic push rod. A clamping pad is fixedly installed at the bottom of the inside of the clamping groove. Both the clamping pad and the inner side of the clamping plate are provided with raised grooves.

[0013] Furthermore, a traction ear seat is fixedly installed on the side of the structural seat.

[0014] Compared with related technologies, the high-precision rolled aluminum profile dimensional detection and correction device proposed in this utility model has the following advantages:

[0015] In this invention, a high-precision rolled aluminum profile dimensional detection and correction device is described. Through a measuring mechanism, when the aluminum profile passes inside the structural frame, an infrared irradiation lamp in the measuring mechanism is activated. The light emitted by the infrared irradiation lamp located on the upper side of the fixed frame shines downwards. The aluminum profile, which is conveyed inside the structural frame, blocks part of the light, thus generating a shadow of a certain width on the lower photosensitive screen. The controller detects the width of the shadow on the photosensitive screen, which is precisely equivalent to the width of the aluminum profile. Additionally, the device utilizes side infrared irradiation... The lamp tubes and photosensitive screens allow for precise calculation of the aluminum profile's height. The controller then adjusts the hydraulic rods in the correction mechanism in real time based on the measured width and height, ensuring the positions of the four sets of folding plates match the correction amount. As the aluminum profile passes through the central area surrounded by the four folding plates, it achieves a correction effect under the guidance of the plates. By combining optical measurement with mechanical correction, the measurement is accurate, the correction is rapid, and the entire process is controlled by the controller, requiring no human intervention. This high correction efficiency enhances practicality. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-5 A high-precision rolling aluminum profile dimension detection and correction device includes a structural frame 1, a traction mechanism 5 at the end of the structural frame 1, a correction mechanism 3 and a measuring mechanism 6 inside the structural frame 1; the measuring mechanism 6 includes a fixed frame 61, two photosensitive screens 62 are fixedly installed inside the fixed frame 61, structural grooves 64 are provided on the corresponding sides of the two photosensitive screens 62, the structural grooves 64 are fixedly installed inside the fixed frame 61, an infrared irradiation lamp tube 65 is fixedly installed inside the structural grooves 64, a protective transparent cover 66 is fixedly installed at the port of the structural grooves 64, and a protective film 63 is applied to the surface of the photosensitive screens 62.

[0024] Through the above-described configuration, the protective transparent cover 66 protects the working space of the infrared irradiation lamp tube 65, and the protective film 63 provides surface protection for the photosensitive screen 62.

[0025] In this method, the traction mechanism 5 includes a structural base 51, on which clamping grooves 52 are symmetrically fixedly installed. A hydraulic push rod 54 is fixedly installed on the clamping groove 52. The output end of the hydraulic push rod 54 passes through to the inside of the clamping groove 52, and a clamping plate 55 is fixedly installed on the output end of the hydraulic push rod 54. A clamping pad 56 is fixedly installed at the bottom of the inside of the clamping groove 52. Both the clamping pad 56 and the inner side of the clamping plate 55 are provided with protruding grooves 57. A traction ear seat 53 is fixedly installed on the side of the structural base 51.

[0026] With the above-described setup, the traction mechanism 5 is placed at the end of the aluminum profile 4. Subsequently, the hydraulic push rod 54 is activated to extend, and the hydraulic push rod 54 drives the clamping plate 55 to clamp the outer wall of the aluminum profile 4 between the clamping plate 55 and the inner side of the clamping groove 52, thus effectively fixing the end of the aluminum profile 4. The traction device is then attached to the traction lug 53, and the traction equipment is activated for linear traction, which can drive the aluminum profile 4 through the correction space formed by the four sets of folding plates 32, thereby correcting the aluminum profile 4. The traction equipment is a common existing device and will not be described in detail here.

[0027] In this method, the correction mechanism 3 includes four sets of hydraulic rods 31, which are respectively fixedly installed on the inner wall of the structural frame 1. A folding plate 32 is fixedly installed on the output end of the hydraulic rod 31, and a stiffening plate 33 is fixedly connected between the side of the folding plate 32 and the side wall of the output end of the hydraulic rod 31.

[0028] By setting up the stiffening plate 33 as described above, the connection strength between the output end of the hydraulic rod 31 and the folding plate 32 is improved.

[0029] In this method, a controller 2 is fixedly installed on the outer wall of the structural frame 1.

[0030] By setting it up in the above manner, controller 2 is used to control the coordinated operation of various electrical components, thereby improving production efficiency.

[0031] In this method, the fixed frame 61 is fixedly installed on the inner wall of the structural frame 1.

[0032] In this method, an aluminum profile 4 is inserted inside the structural frame 1, and the aluminum profile 4 passes between the inner sides of four sets of folding plates 32.

[0033] The working principle of the high-precision rolled aluminum profile dimension detection and correction device provided by this utility model is as follows:

[0034] In use, the aluminum profile 4 to be inspected and corrected is placed in the traction mechanism 5. The symmetrical clamping grooves 52 on the structural seat 51 position the aluminum profile. The hydraulic push rod 54 is activated, and the output end of the hydraulic push rod 54 pushes the clamping plate 55 to move towards the aluminum profile 4 until the clamping plate 55 and the clamping pad 56 clamp the aluminum profile 4. Since the clamping pad 56 and the inner side of the clamping plate 55 are provided with raised grooves 57, the friction with the surface of the aluminum profile is increased, ensuring a firm clamping. After clamping, the external traction equipment is connected to the traction ear seat 53, ready to pull the aluminum profile 4 into the device. The traction equipment is activated, and the aluminum profile 4 is pulled towards the structural frame. The aluminum profile 4 moves within the measuring mechanism 6 area. When the aluminum profile 4 enters the measuring mechanism 6 area, the infrared lamps 65 in the measuring mechanism 6 are activated. The infrared lamps 65 on the upper and side sides of the fixed frame 61 emit infrared light. The aluminum profile 4 blocks some of the light. After the light emitted by the upper infrared lamp 65 is blocked by the aluminum profile, a shadow area is formed on the lower photosensitive screen 62. The controller 2 calculates the width of the aluminum profile 4 by detecting the width of this shadow area. The side infrared lamps 65 cooperate with the corresponding photosensitive screens 62 to calculate the height of the aluminum profile 4 using the same principle. The protective transparent cover 66 protects the infrared irradiation. The lamp tube 65 is protected from dust and debris, while the protective film 63 protects the photosensitive screen 62, ensuring the accuracy of the detection data. After the measuring mechanism 6 acquires the width and height data of the aluminum profile 4, it transmits the data to the controller 2. The controller 2 compares and analyzes the measured data with the preset standard size data, calculates the dimensional deviation of the aluminum profile 4 in the width and height directions, and generates corresponding correction commands based on the deviation. The controller 2 sends the correction commands to the correction mechanism 3, and the four sets of hydraulic rods 31 extend and retract according to the commands. The folding plate 32 at the output end of the hydraulic rods 31 moves under the push of the hydraulic rods 31. Once the aluminum profile 4 reaches the corresponding correction position, it continues to move under the action of the traction device, passing through the area surrounded by four sets of folding plates 32. The folding plates 32 apply external force to the aluminum profile 4, gradually correcting it to the standard size during the passage. After being corrected by the correction mechanism 3, the aluminum profile 4 completes the size detection and correction process. Driven by the traction device, it leaves the structural frame 1 and enters the subsequent production process. Throughout the process, the controller 2 coordinates the traction mechanism 5, the measuring mechanism 6, and the correction mechanism 3 to work together to achieve automated detection and correction without much manual intervention, effectively improving production efficiency and the quality of aluminum profile products.
