Description

Technical Field

[0001] This invention relates to the field of motor housing size measurement technology, and more specifically, to a device and method for measuring the profile of a new energy motor housing based on laser scanning. Background Technology

[0002] As a core drive component of new energy vehicles, the housing contour accuracy of the electric motor directly affects the assembly quality and operating performance of the motor. Therefore, high-precision contour inspection of the motor housing is a crucial step in the manufacturing process. Currently, laser scanning-based contour measurement technology, due to its advantages of non-contact operation, high precision, and high efficiency, has been widely applied to the dimensional inspection of motor housings. Chinese patent document (CN120800204B) discloses a laser measurement device and method for motor housing dimensions. The specification states that it "includes a base and a laser measuring instrument for laser measurement of motor housing dimensions. A motor clamping assembly is provided at the top of the base to clamp the motor. A laser measurement position adjustment assembly for driving the laser measuring instrument to adjust its position is also installed on the base. The motor clamping assembly includes two annular frames symmetrically arranged above the base, fixedly installed on the base, with toothed rings rotatably mounted on the inner side of the annular frames. In operation, the invention, with the motor installed between the two connecting rings and the laser measuring instrument positioned above the motor, rotates to perform laser measurement of the circumferential surface dimensions of the motor housing. When the rotating mounting frame rotates, it can achieve laser measurement of the dimensions at both ends of the motor housing." However, in actual use, the angle of the motor housing still requires multiple manual adjustments to ensure comprehensive detection of the motor contour, resulting in a cumbersome operating method and difficulty in ensuring scanning efficiency. Existing laser scanning measurement devices typically employ a laser emitter and receiver to scan a stationary workpiece point-by-point or line-by-line to obtain three-dimensional contour data of the workpiece surface. However, existing devices still have the following shortcomings in practical applications: First, the workpiece clamping method often uses manual clamping or simple pneumatic clamping, resulting in uneven clamping force. This can easily cause elastic deformation of thin-walled shells during clamping, thus affecting the accuracy of the measurement results. Second, existing devices usually require manual placement of workpieces one by one into the scanning area, or the use of multi-axis turntables to achieve scanning at different angles. The operation steps are cumbersome, the degree of automation is low, and it is difficult to meet the inspection needs of mass production. Third, to achieve omnidirectional contour inspection of the motor housing, the workpiece often needs to be flipped or moved to different inspection stations multiple times. This results in a long inspection cycle, low efficiency, and the accumulation of errors due to multiple clamping. In addition, the control logic of existing devices is relatively complex, requiring the coordination of multiple actuators, which places high demands on the technical skills of operators and is not conducive to large-scale application on production lines.

[0003] In view of this, we propose a laser scanning-based device and method for measuring the profile of a new energy motor housing. Summary of the Invention

[0008] Preferably, the adjustment assembly includes an adjustment wheel, the front of which has twelve sliding grooves, each of which has a guide groove, and each of which has a plurality of rubber blocks fixedly connected. The front of each rubber block has a flat groove, and the rear of each rubber block has an inclined groove. The two adjustment wheels are fixedly connected to the support column and the retainer, respectively.

[0009] Preferably, the control component includes a reinforcing plate, an elastic telescopic sleeve is fixedly connected to one side of the reinforcing plate, the other end of the elastic telescopic sleeve passes through the mounting plate and is fixedly connected to the support plate, a limit ring is fixedly connected to the top of the support plate, and a control valve is fixedly connected to the elastic telescopic sleeve through the reinforcing plate. The limiting ring is sleeved on the outside of the connecting assembly, and the reinforcing plate is fixedly connected above the testing platform.

[0010] Preferably, the conveying assembly includes a conveying pipe, the top end of which is connected to a first telescopic pipe and a second conduit via a pressure valve, and the other end of the first telescopic pipe is fixedly connected to the first conduit. The bottom end of the delivery pipe is connected to the elastic telescopic sleeve, the first telescopic pipe is connected to the sealing assembly through the first conduit, and the other end of the second conduit is connected to the pump.

[0011] Preferably, the sealing assembly includes a sealing shell, a connecting frame is fixedly connected inside the sealing shell, a first elastic telescopic rod is fixedly connected to one side of the connecting frame, and a sealing plate is fixedly connected to the other end of the first elastic telescopic rod. One side of the sealing shell is rotatably connected to one side of the No. 1 conduit, and the sealing shell is in communication with the No. 1 conduit.

[0012] Preferably, the clamping assembly includes a connecting ring, three No. 2 telescopic tubes are fixedly connected to the outside of the connecting ring, and a clamping plate is fixedly connected to the other end of each of the three No. 2 telescopic tubes. A No. 2 elastic telescopic rod is fixedly connected to one side of the clamping plate. The three No. 2 elastic telescopic rods are fixedly connected to the same reinforcing ring. The connecting ring is fixedly connected to the reinforcing ring through an extension rod. Three connecting pipes are fixedly connected to one side of the connecting ring. Three No. 1 limiting blocks are fixedly connected to the inner wall of the connecting ring. Multiple venting valves are provided outside the connecting ring. The connecting ring is connected to the sealing shell via a connecting pipe.

[0013] Preferably, the connecting assembly includes a first mounting ring, which is fixedly connected to a second mounting ring via a reinforcing lever. Three second limiting blocks are fixedly connected inside the second mounting ring, and a limiting groove is formed outside the first mounting ring. The limiting ring is rotatably connected in the limiting groove, and the first mounting ring is fixedly connected to the reinforcing ring by a reinforcing rod.

[0014] A method for measuring the profile of a new energy motor housing based on laser scanning includes the following steps: S1. Place the motor housing to be tested on the clamping assembly, start the pump, and rely on the air pressure generated by the pump and the isolation of the pressure valve to inject gas into the sealing shell, connecting pipe and connecting ring first, so that the three No. 2 telescopic pipes push the clamping plate to apply a uniform clamping force to the outer wall of the motor housing, and complete the clamping step. S2. After clamping is completed, it is difficult for gas to continuously enter the No. 2 telescopic tube. The pressure valve will divert the air and inject the air into the elastic telescopic sleeve, causing the elastic telescopic sleeve to extend synchronously. S3. During the initial movement, the No. 2 limit block in the No. 2 mounting ring will slide in the rear adjustment wheel and slide along the guide groove in the adjustment wheel. At this time, the No. 1 mounting ring, the connecting ring and the clamping plate will drive the motor housing to rotate 90 degrees. After the rotation is completed, the elastic telescopic sleeve continues to extend, and the motor housing will pass under the laser detector to complete the detection of the top of the motor housing. S4. After the initial inspection is completed, the No. 1 limit block in the connecting ring will enter the front adjusting wheel and then the guide groove, thus rotating 90 degrees again. At this time, the control valve opens, the elastic telescopic sleeve retracts, and the No. 1 limit block slides out horizontally along the slide groove. During the reset process, the laser detector scans above it again. After the reset is completed, you only need to run the above steps again to complete the 180-degree inspection of the motor housing.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the design of adjustment, clamping, and connecting components, ensures that when the air pressure inside the sealing component rises to a threshold, the pressure valve automatically switches the air path, guiding gas through the delivery pipe into the control component. The elastic telescopic sleeve then extends, pushing the second mounting ring and the second limiting block to slide within the rear adjusting wheel. At this time, the second limiting block is blocked by the rubber block and slides along the guide groove, subsequently causing the connecting ring to rotate 90 degrees, causing the motor housing to rotate 90 degrees synchronously, ensuring the laser detector can accurately capture the side profile of the housing. Subsequently, the control component continues to extend, pushing the first limiting block within the connecting ring into the front adjusting wheel. The rubber block again guides it to slide along the guide groove, causing the connecting ring to rotate 90 degrees again. At this point, the control valve opens, the elastic telescopic sleeve retracts, and the first limiting block slides horizontally out along the slide groove. During the reset process, the laser detector scans the area above the motor housing again. After the reset is complete, the process can be repeated to complete a 180-degree inspection of the motor housing. The device has two sets of adjustment components on its movement path: a rear component and a front component. When the clamping component moves forward, it passes the rear adjustment component and automatically rotates 90 degrees. After continuing to move forward and completing the upper scan, it contacts the front adjustment component and rotates 90 degrees again. Then, the control valve opens, the component resets, and passes under the laser detector again. During this back-and-forth movement, a continuous 180-degree scan of the upper part of the motor housing is completed. By repeating the above steps, a comprehensive inspection of the housing can be achieved. Compared with existing technologies that require multiple flips or multi-station switching, this device significantly shortens the inspection cycle and reduces the cumulative error caused by multiple clamping operations.

[0016] 2. This invention also incorporates a design for a conveying component and a pump. The core control logic of this device relies entirely on changes in air pressure, eliminating the need for a complex electrical control system. Specifically, after the pump starts, gas is preferentially injected into the clamping component to secure it. When pressure accumulates inside the sealing component, the pressure valve automatically switches the air path, transferring the gas to the control component, which drives the entire clamping component to move forward automatically. From clamping, moving, scanning to resetting, everything is automatically triggered by the sequential distribution of air pressure. Operators only need to control the opening and closing of the pumps on both sides to complete the entire testing process, significantly reducing the difficulty of operation and the technical requirements for personnel, making it easy to promote on a large scale in production lines.

[0017] 3. The present invention also designs a control component to connect one end of the elastic telescopic sleeve to the limiting ring through a support plate. The limiting ring is also fitted into the limiting groove outside the first mounting ring, thereby ensuring that the elastic telescopic sleeve always runs stably along the axial direction during the extension and contraction process. Moreover, the movement of the elastic telescopic sleeve will not affect the rotation of the first mounting ring and the connecting ring. At the same time, the coordinated design of the limiting ring and the support plate effectively suppresses radial sway, ensuring the accuracy and reliability of the entire rotation and reset process.

[0020] like Figures 1 to 8 As shown, the present invention relates to a laser scanning-based device and method for measuring the profile of a new energy motor housing, comprising a detection mechanism 1 and a positioning mechanism 2, wherein the positioning mechanism 2 is located above the detection mechanism 1; The testing mechanism 1 includes a testing platform 11 and two adjusting components 15, both located above the testing platform 11. The positioning mechanism 2 includes a control component 21, a conveying component 22, a sealing component 24, a clamping component 25, and a connecting component 26. The control component 21 is connected to the sealing component 24 via the conveying component 22, the clamping component 25 is connected to the sealing component 24, and the sealing component 24 is connected to the connecting component 26. By designing the adjusting components 15, clamping components 25, and connecting components 26, the device has two sets of components on the moving path: a rear component and a front component. When the adjusting component 15 and clamping component 25 move forward, they pass behind the adjusting component 15 and automatically rotate 90 degrees. After continuing to move forward and completing the upper scan, they contact the front adjusting component 15 again and rotate 90 degrees again. Then, the control valve 216 opens, the component resets, and passes under the laser detector 13 again. During the back-and-forth movement, the upper part of the motor housing completes a continuous 180-degree scan. Only by repeating the above steps can the housing be fully inspected. Compared with the existing technology that requires multiple flips or multiple station switching, this device significantly shortens the inspection cycle and reduces the cumulative error caused by multiple clamping.

[0021] In an embodiment of the present invention, a support frame 12 is fixedly connected above the detection platform 11, and a laser detector 13 is disposed at the top of the support frame 12. A support column 14 is fixedly connected above the detection platform 11. The detection platform 11 is fixedly connected to one of the adjustment components 15 through the support column 14. One end of the control component 21 is connected to the conveying component 22. The conveying component 22 is connected to the pump 23 and the sealing component 24 respectively. The sealing component 24 is connected to the clamping component 25. One side of the clamping component 25 is fixedly connected to the connecting component 26. The control component 21 is sleeved on the outside of the connecting component 26. The upper part of the detection platform 11 is fixedly connected to the support frame 12. A retainer 27 is connected, and the upper part of the retainer 27 is fixedly connected to another adjustment component 15. The pump 23 is fixedly connected above the detection table 11. The device adopts a clamping method in which the second telescopic tube 252 pushes the clamping plate 254 to squeeze outward from the inner wall of the motor housing. Unlike the traditional external clamping method, the clamping force is directly applied to the inner wall of the housing, so that the thin-walled housing maintains its natural contour in the clamping state. This effectively avoids the elastic deformation problem caused by external clamping and ensures the accuracy of laser scanning data from the source. At the same time, multiple second telescopic tubes 252 are evenly distributed, and the clamping force is evenly distributed, further improving the clamping stability.

[0022] In an embodiment of the present invention, the adjusting assembly 15 includes adjusting wheels 151. The front of the adjusting wheel 151 has twelve grooves 152, each groove 152 containing a guide groove 153. Multiple rubber blocks 154 are fixedly connected to each of the twelve guide grooves 153. The front of each rubber block 154 has a flat groove 155, and the rear of each rubber block 154 has an inclined groove 156. Two adjusting wheels 151 are fixedly connected to the support column 14 and the retainer 27, respectively. The control assembly 21 includes a reinforcing plate 211. One side of the reinforcing plate 211 is fixedly connected to an elastic telescopic sleeve 212. The other end of the elastic telescopic sleeve 212 passes through the mounting plate 213 and is fixedly connected to the support plate 214. A limit ring 215 is fixedly connected to the top of the support plate 214. The elastic telescopic sleeve 212 passes through the reinforcing plate 211 and is fixedly connected to... With a control valve 216, a limit ring 215 sleeved on the outside of the connecting component 26, and a reinforcing plate 211 fixedly connected above the testing table 11, the core control logic of this device is entirely based on changes in air pressure, without the need for a complex electrical control system. Specifically, after the pump 23 is started, gas is preferentially injected into the clamping component 25 to complete the fixation. When the internal pressure of the sealing component 24 accumulates, the pressure valve 222 automatically switches the air path and transfers the gas to the control component 21, driving the entire clamping component 25 to move forward automatically. From clamping, moving, scanning to resetting, all are automatically triggered by the sequential distribution of air pressure. Operators only need to control the opening and closing of the pumps 23 on both sides to complete the entire testing process, which greatly reduces the difficulty of operation and the technical requirements for personnel, making it easy to promote on a large scale in the production line. The entire device is based on pneumatic components such as pump 23, conduit, pressure valve 222, telescopic pipe, and regulating component 15. It has no complex motor drive and sensor feedback loop, has a simple structure, low failure rate, and low maintenance cost. At the same time, the pneumatic components have a fast response speed, which can meet the requirements of detection cycle in mass production.

[0023] In another embodiment of the present invention, the conveying assembly 22 includes a conveying pipe 221. The top end of the conveying pipe 221 is connected to a first telescopic pipe 223 and a second conduit 225 via a pressure valve 222. The other end of the first telescopic pipe 223 is fixedly connected to a first conduit 224. The bottom end of the conveying pipe 221 is connected to an elastic telescopic sleeve 212. The first telescopic pipe 223 is connected to a sealing assembly 24 via the first conduit 224. The other end of the second conduit 225 is connected to a pump 23. The sealing assembly 24 includes a sealing shell 241. A connecting frame 242 is fixedly connected inside the sealing shell 241. A first elastic telescopic rod 243 is fixedly connected to one side of the connecting frame 242. The other end of the first elastic telescopic rod 243 is fixedly connected to... There is a sealing plate 244, and one side of the sealing shell 241 is rotatably connected to one side of the first conduit 224. The sealing shell 241 is connected to the first conduit 224. Through the design of the control component 21, one end of the elastic telescopic sleeve 212 is connected to the limiting ring 215 through the support plate 214. The limiting ring 215 is also sleeved in the limiting groove 265 outside the first mounting ring 261, thereby ensuring that the elastic telescopic sleeve 212 always runs stably along the axial direction during the extension and contraction process, and the movement of the elastic telescopic sleeve 212 will not affect the rotation of the first mounting ring 261 and the connecting ring 251. At the same time, the cooperative design of the limiting ring 215 and the support plate 214 effectively suppresses radial sway, ensuring the accuracy and reliability of the entire rotation and reset process.

[0024] In another embodiment of the present invention, the clamping assembly 25 includes a connecting ring 251, three second telescopic tubes 252 are fixedly connected to the outside of the connecting ring 251, and a clamping plate 254 is fixedly connected to the other end of each of the three second telescopic tubes 252. A second elastic telescopic rod 257 is fixedly connected to one side of the clamping plate 254. The three second elastic telescopic rods 257 are fixedly connected to the same reinforcing ring 256. The connecting ring 251 is fixedly connected to the reinforcing ring 256 through an extension rod. Three connecting pipes 255 are fixedly connected to one side of the connecting ring 251. Three first limiting blocks 253 are fixedly connected to the inner wall of the connecting ring 251. Multiple venting valves 258 are provided outside the connecting ring 251. The connecting ring 251 communicates with the sealing shell 241 through the connecting pipes 255. The connecting assembly 26 includes a first mounting ring 261, which is fixedly connected to a second mounting ring 263 through a reinforcing lever. Three second limiting blocks 26 are fixedly connected inside the second mounting ring 263. 4. A limiting groove 265 is provided on the outside of the first mounting ring 261. The limiting ring 215 is rotatably connected in the limiting groove 265. The first mounting ring 261 is fixedly connected to the reinforcing ring 256 through the reinforcing rod 262. After the motor housing is placed into the clamping assembly 25, the pump 23 is started. Gas enters the sealing assembly 24 through the second conduit 225, driving the second telescopic tube 252 to extend synchronously, pushing the clamping plate 254 to tightly adhere to the inner wall of the motor housing to complete the adaptive clamping. Because a sealing shell 241 is provided, when gas enters the sealing shell 241, it will squeeze the sealing plate 244, causing the first elastic telescopic rod 243 to contract. At this time, the gas will enter the second telescopic tube 252 along the sealing shell 241. When the pressure valve 222 stops injecting air into the sealing shell 241, the first elastic telescopic rod 243 will push the sealing plate 244 to seal the sealing shell 241, preventing gas leakage and ensuring the stability of the clamping plate 254 when fixing the motor housing.

[0025] Working principle: This embodiment provides a new energy motor housing contour measurement device and method based on laser scanning. When in use, after the motor housing is placed into the clamping assembly 25, the pump 23 is started and the gas enters the sealing assembly 24 through the second conduit 225, driving the second telescopic tube 252 to extend synchronously, pushing the clamping plate 254 to tightly adhere to the inner wall of the motor housing to complete adaptive clamping. When the air pressure inside the sealing assembly 24 rises to the threshold, the pressure valve 222 automatically switches the air path, guiding the gas through the delivery pipe 221 into the control assembly 21. The elastic telescopic sleeve 212 then extends and pushes the second mounting ring 263 and the second limiting block 264 to slide within the adjusting wheel 151 at the rear. At this time, the second limiting block 264 is blocked by the rubber block 154 and slides along the guide groove 153, thereby driving the connecting ring 251 to rotate 90 degrees, causing the motor housing to rotate 90 degrees synchronously, ensuring that the laser detector 13 can accurately capture the side profile of the housing; subsequently The control component 21 continues to extend, pushing the first limit block 253 inside the connecting ring 251 into the front adjusting wheel 151. The rubber block 154 guides it to slide along the guide groove 153 again, causing the connecting ring 251 to rotate 90 degrees again. At this time, the control valve 216 opens, the elastic telescopic sleeve 212 retracts, and the first limit block 253 slides horizontally out along the slide groove 152. During the reset process, the laser detector 13 scans above it again. After the reset is completed, it is only necessary to run the above steps again to complete the 180-degree detection of the motor housing.

[0026] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.

10. A method for measuring the profile of a new energy motor housing based on laser scanning, comprising the laser scanning-based device for measuring the profile of a new energy motor housing as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. Place the motor housing to be tested on the clamping assembly (25), start the pump (23), and rely on the air pressure generated by the pump (23) and the isolation of the pressure valve (222) to inject gas into the sealing shell (241), the connecting pipe (255) and the connecting ring (251) in advance, so that the three No. 2 telescopic pipes (252) push the clamping plate (254) to apply a uniform clamping force to the outer wall of the motor housing, and complete the clamping step; S2. After clamping is completed, gas is difficult to continuously enter the second telescopic tube (252). The pressure valve (222) will divert the air and inject the air into the elastic telescopic sleeve (212), causing the elastic telescopic sleeve (212) to extend synchronously. S3. During the initial movement, the second limiting block (264) in the second mounting ring (263) will slide in the rear adjusting wheel (151) and slide along the guide groove (153) in the adjusting wheel (151). At this time, the first mounting ring (261), the connecting ring (251) and the clamping plate (254) will drive the motor housing to rotate ninety degrees. After the rotation is completed, the elastic telescopic sleeve (212) will continue to extend, and the motor housing will pass under the laser detector (13) to complete the detection above the motor housing. S4. After the initial test is completed, the first limit block (253) in the connecting ring (251) will enter the front adjusting wheel (151) and then enter the guide groove (153), thus rotating 90 degrees again. At this time, the control valve (216) opens, the elastic telescopic sleeve (212) retracts, and the first limit block (253) will slide horizontally out along the slide groove (152). During the reset process, the laser detector (13) scans above it again. After the reset is completed, the 180-degree test of the motor housing can be completed by running the above steps again.
