Technical Field

[0001] This utility model relates to the field of titanium alloy dimension measurement technology, specifically to an online three-dimensional dimension measurement device for titanium alloy high-temperature forging process. Background Technology

[0002] Titanium alloy forgings are commonly used in high-end fields such as aerospace and military, where components require extremely high dimensional accuracy. Three-dimensional measurement ensures that the forging dimensions are within the design tolerances, especially during the forging process. It also helps operators control the degree of deformation and guide zonal forging. Currently, most production processes rely on manual measurement, requiring operators to use calipers and micrometers after the workpiece has cooled. This method is inefficient, lacks real-time performance, and cannot achieve accurate measurement of workpieces with complex curved surfaces or under high-temperature conditions. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this invention is to provide a reasonably designed online three-dimensional dimension measurement device for high-temperature forging of titanium alloys. This device can perform real-time three-dimensional dimension measurement of workpieces under high-temperature conditions, and the measurement data is accurate and reliable.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A three-dimensional online measurement device for titanium alloys during high-temperature forging includes a fixing mechanism, a dimension detection mechanism, and a cooling mechanism; wherein: The fixing mechanism includes a first fixing frame and a second fixing frame; The size detection mechanism includes a 3D lens, a 2D lens, and an infrared lens; wherein the 3D lens is mounted on a second fixed frame, while the 2D lens and the infrared lens are mounted on a first fixed frame; The cooling mechanism includes multiple cooling metal hoses, which are connected to an infrared lens and a 3D lens respectively. All the cooling metal hoses are ultimately connected to a cooling compressed air source.

[0005] Furthermore, another 2D lens is also mounted on the second mounting bracket.

[0006] Furthermore, the infrared lenses are two lenses, located on the left and right sides of the 2D lens on the first mounting bracket.

[0007] Furthermore, the first fixing frame includes a small bracket and a fixing clamp, wherein the fixing clamp is fixed on the small bracket, two infrared lenses are respectively fixed on the left and right ends of the fixing clamp, and the corresponding 2D lens is fixed between the two infrared lenses.

[0008] This invention features shock-absorbing rubber pads on the fixed pipe clamps, at positions where two infrared lenses and corresponding 2D lenses are mounted.

[0009] This invention also includes an adjusting ball valve in each cooling metal hose; the 3D lens of this invention uses a high-temperature industrial blue laser scanner camera.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a 3D lens to acquire three-dimensional point cloud data, a 2D lens to collect surface features, and two infrared lenses to compensate for temperature deformation errors.

[0012] The present invention will now be further described in conjunction with specific embodiments and accompanying drawings. Parts not detailed herein are based on existing technology and common knowledge in the art. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments described herein. Example

[0013] In this embodiment, based on the actual situation of the field survey and combined with the current advanced process technology, the original manual measurement device was modified to design an online three-dimensional dimension measurement device for the high-temperature forging process of titanium alloys, integrating 2D measurement, 3D measurement, and infrared measurement. When measuring the three-dimensional dimensions of the forged workpiece, the device first uses an infrared lens to sense the surface temperature of the forging using infrared light, capturing images in low-light environments. Under complex lighting conditions, it assists the 2D and 3D lenses in working, capturing a planar image of the forging surface using a 2D camera to capture a two-dimensional image of the forging for edge monitoring feature point recognition and auxiliary positioning. After preliminary identification of the forging, the 3D lens uses stereo vision technology to generate a depth map of the forging, obtaining the three-dimensional structural information of the forging, measuring depth and shape, thus making the measured three-dimensional dimensions of the forging more accurate.

[0014] Please refer to Figure 1 The three-dimensional online measurement device for the high-temperature forging process of titanium alloy of this utility model includes a dimension detection mechanism 1, a fixing mechanism 2, and a cooling mechanism 3.

[0015] The dimensional inspection mechanism 1 includes a 3D lens 11, a first 2D lens 12, a second 2D lens 13, a first infrared lens 14, a second infrared lens 15, a first junction box 16, and a second junction box 17. The fixing mechanism includes a first fixing frame and a second fixing frame, wherein the first fixing frame includes a small bracket 21 welded on-site and a fixing pipe clamp 22, the fixing pipe clamp 22 being fixedly connected to the right end of the small bracket 21; the second fixing frame includes a fixing support column 23 and a round pipe support clamp 24.

[0016] Specifically, three lens clamps are fixedly connected to the fixing clamp 22. The first infrared lens 14 is mounted on the lens clamp located at the left end of the fixing clamp 22, the second infrared lens 15 is mounted on the lens clamp located at the right end of the fixing clamp 22, and the first 2D lens 12 is fixed on the lens clamp between the first infrared lens 14 and the second infrared lens 15. The lens clamps are C-clamps or figure-eight clamps used in the prior art for assembling lenses. If necessary, a shock-absorbing rubber pad can be fixedly connected to the inner wall of each lens clamp. The second junction box 17 is fixed to the lower end of the small bracket 21. The function of the second junction box 17 is to branch the main cable to multiple branches, providing power distribution and / or signal transmission for the first 2D lens 12, the first infrared lens 14, and the second infrared lens 15. A 24V DC power line is led out from the power distribution line of the second junction box 17 and connected to the DC interface of the first 2D lens 12, the first infrared lens 14, and the second infrared lens 15 respectively. Network cables are led out from the second junction box 17 and connected to the RJ45 interfaces of the first 2D lens 12, the first infrared lens 14, and the second infrared lens 15, respectively.

[0017] The cylindrical tube bracket clamp 24 is locked onto the fixed support column 23, and the 3D lens 11 is clamped and fixed onto the cylindrical tube bracket clamp 24 via a quick-release plate. The second 2D lens 13 is fixed to the upper end of the fixed support column 23, and the first junction box 16 is fixedly connected to the portion of the fixed support column 23 below the 3D lens 11. The function of the cylindrical tube bracket clamp 24 is to fix the 3D lens 11. The cylindrical tube bracket clamp 24 is locked onto the fixed support column 23, and a conventional quick-release plate is fixedly connected to the outside of the cylindrical tube bracket clamp 24, and then the 3D lens 11 is clamped and fixed onto the quick-release plate. The first junction box 16 provides power distribution and / or signal transmission for the 3D lens 11 and the second 2D lens 13. A 24V DC power supply line is led out from the power distribution line of the first junction box 16 and connected to the DC interface of the 3D lens 11 and the second 2D lens 13 respectively. A network cable is led out from the first junction box 16 and connected to the RJ45 interface of the 3D lens 11 and the second 2D lens 13 respectively.

[0018] Because it is used in a high-temperature environment, cooling is required for each high-power lens. Since the first junction box 6 connects to the 3D lens (which has high power, its junction box also needs cooling, while the second junction box is relatively far from the high-temperature zone and does not require cooling), the dimensional detection mechanism is connected to a cooling mechanism. This cooling mechanism includes a first cooling metal hose 31, a second cooling metal hose 32, a third cooling metal hose 33, a fourth cooling metal hose 34, and a fifth cooling metal hose 35. The first and second cooling metal hoses 31 and 32 are connected to the first infrared lens 14, the fifth cooling metal hose 35 is connected to the second infrared lens 15, the third cooling metal hose 33 is connected to the 3D lens 11, and the fourth cooling metal hose 34 is connected to the first junction box 16. All cooling metal hoses have one end inserted into the corresponding lens housing or the first junction box 16, with the hose cavity communicating with the corresponding lens housing cavity or the first junction box 16 cavity. The other end of all cooling metal hoses is ultimately connected to a compressed air source, and the compressed air must be dried. Each cooling metal hose is also connected to a ball valve in the conventional manner to regulate the flow and control the cooling effect.

[0019] In this embodiment, the dimensional inspection mechanism 1 includes two infrared lenses. The infrared lenses use infrared light to sense the surface temperature of the forging and capture images in low-light environments. In other embodiments, there may be one, three, or more lenses.

[0020] Therefore, the dimensional inspection mechanism 1 captures images in low-light environments using the first infrared lens 14 and the second infrared lens 15, assisting the 2D and 3D lenses in working under complex lighting conditions. The first 2D lens 12 and the second 2D lens 13 capture two-dimensional images of the forging for edge detection. The 3D lens 11 uses stereoscopic vision technology, combining the images from the infrared and 2D lenses, to generate a depth map of the forging, thus obtaining its three-dimensional structural information.

[0021] Therefore, when the three-dimensional online measurement device for the high-temperature forging process of titanium alloy of this utility model is working, dry compressed air is delivered through the cooling metal hose to cool the corresponding lens and the first junction box.

[0022] It should be noted that the inventive point of this embodiment lies in the connection and combination relationship of the structure, and the camera lens monitoring technology involved can be implemented using common technical means in the field.

[0023] Based on the above, the forging workpiece dimension measurement process in this embodiment is as follows: Step 1) Fix the first infrared lens 14, the second infrared lens 15, the first 2D camera 12, the second 2D infrared lens 13, and the 3D camera 11 using the fixing mechanism, and fix them at a position 10 meters away from the forging machine. The first fixing mechanism and the second fixing mechanism are set opposite to each other, and all lenses are aligned with the forging machine to forge the workpiece. Step 2) One-click start of the three-dimensional online measurement device for the high-temperature forging process of titanium alloy of this utility model; Step 3) The measuring device continuously monitors the forging screen of the forging machine. When a forging appears on the screen, it automatically starts measuring dimensions. First, the first infrared lens 14 and the second infrared lens 15 begin to work. The first infrared lens 14 is responsible for low-wave infrared light, and the second infrared lens 15 is responsible for high-wave infrared light. When the temperature of the first infrared lens 14 and the second infrared lens 15 is detected to be too high, the first cooling metal hose 31, the second cooling metal hose 32, and the fifth cooling metal hose 35 respectively supply compressed air to the first infrared lens 14 and the second infrared lens 15 to cool the lenses. Step 4) After the two infrared lenses complete infrared monitoring, they transmit real-time data to the first 2D lens 12 and the second 2D lens 13. The two 2D lenses work together to capture images of the forging from different angles and combine the captured data with the data captured by the first infrared lens 14 and the second infrared lens 15. The two 2D lenses capture two-dimensional images of the forging for edge monitoring feature point recognition and to assist in positioning. Step 5) After the two 2D lenses complete the video monitoring of the 2D image of the forging, the real-time processed data is transmitted to the 3D lens 11. The 3D lens 11 uses stereoscopic vision technology to generate a depth map of the forging, obtain the three-dimensional structural information of the forging, and measure its depth and shape. When the temperature of the 3D lens 11 is detected to be too high, the third cooling metal hose will supply compressed cooling air to the 3D lens 11. At the same time, during the operation of this invention, the fourth cooling metal hose 34 continuously supplies dry compressed air to the first junction box 16 to reduce the temperature of the junction box in the high-temperature environment.
