DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example 1: Reference Figures 1-10 , the flange precision detection equipment of the automobile electronic brake system includes: 1. The flange precision detection equipment of the automobile electronic brake system is characterized in that it includes: a frame 1, a positioning column 2, a three-dimensional laser scanner 3, a mounting platform 4 and a cooling mechanism, the mounting platform 4 of the frame 1 is connected to the bottom of the positioning column 2, the scanning end of the three-dimensional laser scanner 3 connected to the frame 1 is set toward the positioning column 2, and a cooling mechanism is provided above the three-dimensional laser scanner 3, and the cooling mechanism is connected to the frame 1.

[0034] The principles and beneficial effects of the above scheme are:

[0035] A flange is mounted on the positioning column 2. After the bottom of the flange is in stable contact with the top of the mounting platform 4, the 3D laser scanner 3 is started to measure the flange.

[0036] The specific model of the 3D laser scanner 3 is the Hexagon Leica RTC360 in the existing technology, which is suitable for measuring workpieces and then monitoring their accuracy. The working principle of the laser 3D scanner is the same as that in the existing technology. It obtains the 3D coordinate information of the surface of the object based on the laser ranging principle, and then reconstructs the 3D model of the object. The acquired data is then transmitted to a computer with software such as Geomagic Studio or PolyWorks, and the parameters are detected using the relevant software. When the 3D laser scanner 3 works for a period of time, it will generate heat. In order to prevent the heat of the device from being transferred to the optical element of the 3D laser scanner 3 and causing light distortion, the cooling mechanism is started at this time to cool the 3D laser scanner 3, thereby ensuring that the device continues to maintain stable detection accuracy of the flange when working.

[0037] Example 2: Reference Figures 1-10 The cooling mechanism includes: a fan 5 and a cable 6. The rack 1 is connected to the fan 5. The output end of the fan 5 is set toward the three-dimensional laser scanner 3. The three-dimensional laser scanner 3 is connected to the power supply through the cable 6.

[0038] The principles and beneficial effects of the above scheme are:

[0039] When cooling the three-dimensional laser scanner 3, the fan 5 is powered, and the output end of the fan 5 outputs airflow to the three-dimensional laser scanner 3 for cooling, thereby reducing the complexity of the device and ensuring the cooling efficiency of the device.

[0040] Example 3: Reference Figures 1-10 The cooling mechanism also includes: a PLC and a DC fan speed regulator. The rack 1 is connected to the PLC and the DC fan speed regulator. The fan 5 is connected to the power supply through cable 2. The DC fan speed regulator is electrically connected to one side of the PLC, and the other side of the PLC is electrically connected to the coil. The coil is sheathed on cable 6.

[0041] The principles and beneficial effects of the above scheme are:

[0042] The power supply supplies power to the 3D laser scanner 3 via cable 6. The PLC in the device obtains the induced electricity of cable 6 through the coil. Since the 3D laser scanner 3 scans flanges during operation, the scanning time of larger flanges is longer and the heat generated is greater. When detecting the same batch of flanges, the greater the number of flanges, the greater the heat generated. Therefore, a program can be written in the PLC program to record the safe power-on time and the number of safe power-on times of the 3D laser scanner 3. When the feedback obtained by the PLC exceeds the safe power-on time or the number of safe power-on times, the PLC uses the DC fan speed regulator to control the speed of the fan 5 by linearly changing the voltage or current on the control cable 2. The specific model of the DC fan speed regulator is: MEAN WELLSDR-60-24.

[0043] When the device performs the cooling action, it reduces the setting of electrical components, greatly reduces the manufacturing cost of the device, and greatly improves the convenience of the user when repairing and maintaining the device;

[0044] Cable 6 and cable 2 are circuits that supply power to the load in the device and drive the load to work.

[0045] Example 4: Reference Figures 1-10 The end of the frame 1 is connected to two rollers 7 of a conveyor belt mechanism, and the two rollers 7 are connected by a conveyor belt transmission. The end of one roller 7 is connected to the output end of a motor 8, and the motor 8 is connected to the frame 1. The conveyor belt is arranged above the top of the positioning column 2.

[0046] The principles and beneficial effects of the above scheme are:

[0047] In order to reduce the difficulty of flange transportation when inspecting the flange, a conveyor belt mechanism is set up in the device. After the motor 8 is started, its output end drives a roller 7 to rotate forward, and through the cooperation of another roller 7, the conveyor belt transports the flange, which greatly reduces the manpower cost invested in the use of the device.

[0048] Example 5: Reference Figures 1-10 The frame 1 is connected to a guide rail 12, the output end of the motor 2 9 on the guide rail 12 is connected to the end of the screw 10, the screw 10 is rotatably connected to the guide rail 12, and a screw block 11 is connected to the screw 10, one side of the screw block 11 is slidably connected to the guide rail 12, and the other side of the screw block 11 is connected to the clamping mechanism.

[0049] The clamping mechanism includes a lifting mechanism. The other side of the screw block 11 is connected to the lifting mechanism, and the output end of the bottom of the lifting mechanism is connected to a clamping claw.

[0050] The principles and beneficial effects of the above scheme are:

[0051] After the flange is transferred from the conveyor belt to the side of the positioning column 2, the output end of the lifting mechanism drives the output end of the clamping claw to move downward, and uses the clamping claw to clamp the flange. The output end of the lifting mechanism continues to move upward, and then the motor 2 9 is started. The output end of the motor 2 9 drives the screw 10 to rotate forward. With the cooperation of the guide rail 12, the screw block 11 drives the lifting mechanism to move above the positioning column 2. The output end of the lifting mechanism drives the clamping claw to move downward to fit the flange on the positioning column 2. The lifting mechanism drives the clamping claw to move upward, and the output end of the motor 2 9 drives the screw 10 to reverse. With the cooperation of the guide rail 12, the screw block 11 drives the lifting mechanism to reset, preparing for the clamping of the next flange.

[0052] The use of the clamping jaws further avoids the operator's manual handling of the flange, preventing accidents such as injuries to people during the handling of the test piece, and also prevents the flange from being rusted by water stains on the operator's body during the handling.

[0053] The lifting mechanism specifically includes a mounting plate, to which the motor component is connected, the output end of the motor component is connected to the screw component, the bottom of the mounting plate is connected to the top of the guide rod, the screw is threadedly connected to the top of the clamp, and the guide rod is slidingly connected to the top of the clamp; the clamp is a hydraulically driven clamping device in the prior art; the lifting mechanism and the clamp are both commonly used devices in the prior art, which are easy to inspect and maintain and have strong replaceability.

[0054] Example 6: Reference Figures 1-10 The bottom of the frame 1 is rotatably connected to two turntables 13, one turntable 13 is rotatably connected to the ends of three rubber rollers 14, and the three rubber rollers 14 are arranged around the center of the turntable 13. The top of one rubber roller 14 contacts and cooperates with the bottom of the conveyor belt to provide tension to the bottom of the conveyor belt, and the other end of the rubber roller 14 is rotatably connected to another turntable 13.

[0055] The three rubber rollers 14 are arranged at equal distances from each other.

[0056] The principles and beneficial effects of the above scheme are:

[0057] When the conveyor belt rotates forward, it contacts and cooperates with a rubber roller 14 at the bottom of the conveyor belt. The rubber roller 14 can apply tension to the bottom of the conveyor belt to prevent the conveyor belt from slipping during movement, further improving the stability of the conveyor belt during flange transportation.

[0058] Both turntables 13 are rotatably connected to the bottom of the frame 1. After one rubber roller 14 rubs against the bottom of the conveyor belt for a period of time, in order to prevent the temperature of the rubber roller 14 from rising due to excessive friction, the turntable 13 can be rotated to make the other rubber roller 14 contact and cooperate with the bottom of the conveyor belt, thereby further avoiding premature aging of the rubber roller 14 and overheating of the bottom of the conveyor belt, thereby effectively extending the service life of the components.

[0059] Example 7: Reference Figures 1-10 A gear 15 is connected to the end side wall of each rubber roller 14 , and the multiple gears 15 are meshed and connected through a gear 2 16 , and the gear 2 16 is rotatably connected to the middle of the turntable 13 .

[0060] The turntable 13 rotatably connected to the gear 2 16 is connected to the end of the rotating shaft 17, and the rotating shaft 17 is rotatably connected to the frame 1. The rotating shaft 17 is connected to a driving disk 18, and the side wall of the driving disk 18 is provided with three U-shaped grooves 19. The side wall of the driving disk 18 is provided with three arc surfaces 20, each arc surface 20 is arranged between two U-shaped grooves 19, and the arc surface 20 is frictionally matched with the side wall of the guide disk 21. The guide disk 21 is rotatably connected to the frame 1 through the rotating shaft 22, and the rotating shaft 22 is connected to a pulley 23. The pulley 23 is connected to the pulley 25 for transmission through a belt 24. The pulley 25 is connected to a roller 7. The middle part of the guide disk 21 is connected to the top of a rod body 26, and the bottom end of the rod body 26 is connected to the end of a driving rod 27. The other end of the driving rod 27 slides with the U-shaped groove 19.

[0061] The principles and beneficial effects of the above scheme are:

[0062] When a rubber roller 14 rubs against the conveyor belt, a gear 15 rotates, and through the meshing connection of gear 2 16, it can drive the other gears 15 to rotate on the turntable 13;

[0063] The rotating roller 7 drives the pulley 25 to rotate, and drives the pulley 23 to rotate through the belt 24, further driving the rotating shaft 22 to rotate, and the guide plate 21 synchronously drives the rod body 26 and the driving rod 27 to rotate. The driving rod 27 cooperates with the U-shaped groove 19 on the driving plate 18 to drive the driving plate 18 to rotate in the opposite direction relative to the guide plate 21. Therefore, the driving plate 18 can drive the turntable 13 to rotate in the opposite direction relative to the conveyor belt through the rotating shaft 17. Therefore, after one rubber roller 14 rubs with the conveyor belt for a period of time, another rubber roller 14 can be replaced to rub the conveyor belt. The friction between the rubber roller 14 and the conveyor belt can clean the dust on the conveyor belt; the U-shaped groove 19 on the driving plate 18 cooperates with the driving rod 27 to realize the intermittent rotation of the turntable 13, and then realize the intermittent friction between the rubber roller 14 and the conveyor belt, which greatly reduces the complexity of the device.

[0064] Example 8: Reference Figures 1-10 The side of the rubber roller 14 provided below the conveyor belt contacts and cooperates with the end face of the friction plate 28. The top of the friction plate 28 is provided with a chamfer 29, which is arranged toward the top of the turntable 13. The end face of the friction plate 28 is connected with the open ends of multiple drainage pipes 30. The other end of the drainage pipe 30 is connected to the end of the spring 31 through a sealing disk. The other end of the spring 31 is connected to the sealing disk 2, and the sealing disk 2 is connected to the tube body 32. The drainage pipe 30 and the tube body 32 are slidably sealed. The bottom of the tube body 32 is connected to the top of the tube body 2 33. The top of the tube body 2 33 is connected to the liquid guide hole 34. The liquid guide hole 34 is provided to connect the liquid guide hole. The hole 34 is provided on the bottom side wall of the drain pipe 30, and the tube body 2 33 is slidably sealed with the tube body 3 35. The bottom of the tube body 2 33 is connected to the top of the spring 2 36 through the sealing disk 3, and the bottom of the spring 2 36 is connected to the bottom wall of the tube body 3 35. The tube body 3 35 is connected to the frame 1. A waist-shaped hole 37 is provided through the side wall of the tube body 2 33, and the top wall of the waist-shaped hole 37 is arranged toward the bottom wall of the tube body 4 38. The end of the tube body 4 38 is connected to the side wall of the tube body 3 35, and the other end of the tube body 4 38 is connected to the liquid storage tank on the frame 1. The liquid storage tank is arranged above the chamfer 29, and the liquid storage tank is filled with ethanol.

[0065] The principles and beneficial effects of the above scheme are:

[0066] When one rubber roller 14 rotates, the other rubber rollers 14 rotate synchronously. When the drive plate 18 rotates, the multiple rubber rollers 14 rotate synchronously with the drive plate 18. When one rubber roller 14 stops contacting with the friction plate 28, under the elastic force of the spring 31, the second tube 33 and the liquid guide hole 34 are no longer connected, which can prevent the ethanol inside the drain pipe 30 from being discharged and prevent the waste of ethanol.

[0067] As the drive disc 18 rotates, the rubber roller 14, which was originally in friction with the conveyor belt, applies pressure to the friction plate 28 again, connecting the second tube 33 with the liquid guide hole 34. To prevent the side of the rubber roller 14 from being cut by the friction plate 28 during the rotation process, a chamfer 29 is provided on the friction plate 28.

[0068] After production, the flange is protected with anti-rust oil. Since the rubber roller 14 and the conveyor belt are in frictional contact, the anti-rust oil will stick to the rubber roller 14. When there is too much anti-rust oil on the rubber roller 14, the friction between the rotating rubber roller 14 and the friction plate 28 decreases. Under the action of the elastic force of the second spring 36, the second tube 33 moves upward within the third tube 35, and the conductive area between the waist-shaped hole 37 and the fourth tube 38 increases. Therefore, the output of ethanol in the liquid storage tank through the drain pipe 30 increases, thereby increasing the dissolution rate of the anti-rust oil on the rubber roller 14.

[0069] When the anti-rust oil on the rubber roller 14 is too little or does not exist, the friction force exerted by the rotating rubber roller 14 on the friction plate 28 increases, so the friction plate 28 moves downward, the length of the spring 2 36 becomes shorter, the conductive area between the waist-shaped hole 37 and the tube 4 38 decreases, and the amount of ethanol discharged decreases, thereby achieving precise control of the amount of ethanol discharged;

[0070] The liquid storage tank is arranged above the chamfer 29, so that ethanol can flow out of the drain pipe 30 under the action of gravity, avoiding the need for a liquid supply power mechanism in the device.

[0071] Example 9: Reference Figures 1-10 The side of the other rubber roller 14 provided below the conveyor belt contacts and cooperates with the end face of the second friction plate 39. The bottom of the second friction plate 39 is provided with a chamfer 240, which is arranged parallel to the chamfer 29. The end face of the second friction plate 39 is connected with the open ends of multiple air supply pipes 41. The other end of the air supply pipe 41 is connected to the end of the spring 3 42 through the sealing disk 4. The other end of the spring 3 42 is connected to the sealing disk 5 of the tube body 5 43. The tube body 5 43 is slidably sealed with the air supply pipe 41. The bottom of the tube body 5 43 is connected to the top of the tube body 6 44. The tube body 6 44 In coordination with the air inlet hole 45, the air inlet hole 45 is provided on the bottom side wall of the air supply pipe 41. The tube body 6 44 is slidably sealed with the tube body 7 46. The bottom of the tube body 6 44 is connected to the top of the spring 47 through the sealing disk 6. The bottom of the spring 47 is connected to the bottom wall of the tube body 7 46. The side wall of the tube body 7 46 is connected to the end of the tube body 8 48. A waist-shaped hole 2 49 is provided through the side wall of the tube body 6 44. The top wall of the waist-shaped hole 2 49 is arranged toward the bottom wall of the tube body 8 48. The other end of the tube body 8 48 is connected to the output end of the air pump on the frame 1. A pressure relief valve is provided on the tube body 8 48.

[0072] The principles and beneficial effects of the above scheme are:

[0073] When the rubber roller 14 after being cleaned with ethanol is driven by the driving disk 18, it begins to rub against the second friction plate 39. In order to prevent the side of the rubber roller 14 from being cut, a second chamfer 40 is provided on the second friction plate 39.

[0074] When there is too little ethanol on the rubber roller 14, the friction between the rubber roller 14 and the second friction plate 39 is large. Therefore, under the elastic force of the fourth spring 47, the sixth tube 44 moves upward in the seventh tube 46, and the conductive area between the second waist-shaped hole 49 and the eighth tube 48 decreases. As a result, the air volume output from the air supply pipe 41 by the air pump decreases, keeping some ethanol on the rubber roller 14. This prevents the rubber roller 14 from pulling the second friction plate 39 upward after the friction with the second friction plate 39 ends, thereby preventing the spring 47 from working under excessive tension for a long time and causing metal fatigue.

[0075] When there is too much ethanol on the rubber roller 14, the friction between the rubber roller 14 and the friction plate 2 39 is small, and the conductive area between the waist-shaped hole 2 49 and the tube body 8 48 is increased, so the ethanol on the rubber roller 14 can be dried efficiently.

[0076] After drying, a certain amount of ethanol remains on the rubber roller 14, which is convenient for cleaning the anti-rust oil on the conveyor belt. After the ethanol on the rubber roller 14 is used up, it can directly absorb part of the anti-rust oil, thereby improving the cleaning efficiency of the device. Cleaning the anti-rust oil on the conveyor belt can prevent the flange friction on the conveyor belt from being too small, thereby preventing the flange from slipping during transportation, thereby avoiding damage to the flange, and ultimately ensuring the accuracy of the detection;

[0077] When the friction plate 2 39 is subjected to pressure, the air supply pipe 41 moves into the tube body 5 43 , the spring 3 42 is compressed, and then the tube body 6 44 and the air inlet 45 are connected, thereby achieving the mechanism for drying the rubber roller 14 ;

[0078] When the friction plate 2 39 is no longer under pressure, the air supply pipe 41 moves outward from the pipe body 5 43 under the elastic force of the spring 3 42, ending the conduction between the pipe body 6 44 and the air inlet 45. In order to reduce the repeated starting of the air pump in the device, a pressure relief valve is provided on the pipe body 8 48. When the internal pressure of the pipe body 6 44 is too high, the pressure of the pipeline structure can be relieved to prevent the device from malfunctioning.

[0080] Install a flange on the positioning column 2;

[0081] After the flange is installed, the three-dimensional laser scanner 3 is powered by the cable 6;

[0082] After the three-dimensional laser scanner 3 is powered on, the flange is measured to finally obtain the flange size parameters.

[0083] The principles and beneficial effects of the above scheme are:

[0084] After the flange is mounted on the positioning column 2, the three-dimensional laser scanner 3 is powered by the cable 6. The three-dimensional laser scanner 3 can accurately scan the flange and obtain accurate detection data.
