Description

Technical Field

[0001] The present invention belongs to the technical field of calibration of electronically controlled actuators, and particularly relates to an angle calibration device and method for a turbocharged electronically controlled actuator. Background Technique

[0002] A turbocharger is actually an air compressor that increases the intake air volume by compressing air. It uses the inertial impulse of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, and the impeller compresses the air sent through the air filter pipeline, making it pressurized and entering the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously. The impeller compresses more air into the cylinder. The increase in air pressure and density allows more fuel to be burned. By correspondingly increasing the fuel quantity and adjusting the engine speed, the output power of the engine can be increased. The turbocharged actuator is an actuator device that controls the turbocharger. It controls the valve through the displacement of the push rod corresponding to the input pressure, causing the pressure of the turbocharger to fluctuate within a certain predetermined range to achieve dynamic balance.

[0003] The electronically controlled actuator is one of the important components of the turbocharger and belongs to the electronically controlled component. After the production and processing of the electronically controlled actuator are completed, it needs to be angle calibrated to meet the actual use requirements of the electronically controlled actuator. In actual operation, the electronically controlled actuator is often calibrated manually. The manual operation method requires a large amount of manpower, and the calibration accuracy is low, making it difficult to meet the actual operation requirements. Summary of the Invention

Nor are they used to limit the present invention. They are merely used to distinguish components or operations described with the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] Combined Figures 1 to 3 As shown, a turbocharged electronic control actuator angle calibration device calibrates the angle of the electronic control actuator. The calibration device includes

[0035] A calibration platform 10 is provided with a calibration disc 11 thereon. A centering chuck 111 for positioning the electronic control actuator is provided on the calibration disc 11. In this embodiment, the centering chuck 111 used is a three-jaw chuck. The electronic control actuator is centered by the centering chuck 111 to ensure the precise position of the electronic control actuator.

[0036] Specifically, a driving motor 60 is provided at the bottom of the calibration disc 11. The driving motor 60 is connected to the centering chuck 111. The number of centering chucks 111 is multiple and they are evenly distributed on the surface of the calibration disc 11. The number of driving motors 60 is the same as that of the centering chucks 111 and they are in one-to-one correspondence. The driving motor 60 can drive the centering chuck 111 to rotate, thereby deflecting the angle of the electronic control actuator and ensuring the operation accuracy of subsequent calibration.

[0037] The calibration device of this embodiment further includes a calibration group 20. The calibration group 20 includes a pre-calibration sensor 21 and a calibration block 22. The pre-calibration sensor 21 scans the electronic control actuator before calibration, and the calibration block 22 calibrates the electronic control actuator. After the pre-calibration sensor 21 scans the electronic control actuator, the calibration block 22 can calibrate the electronic control actuator.

[0038] Specifically, the calibration group 20 further includes a calibration cylinder 23. The piston rod of the calibration cylinder 23 is connected to the calibration block 22 to drive the calibration block 22. The pre-calibration sensor 21 is a line scan sensor. After the line scan sensor scans the electronic control actuator, the calibration cylinder 23 drives the calibration block 22 to calibrate the electronic control actuator.

[0039] The calibration device of this embodiment further includes a driving module 30. The driving module 30 includes an X-axis module 31 and a Y-axis module 32 that moves along the length direction of the X-axis module 31. The calibration group 20 moves along the length direction of the Y-axis module 32. The presence of the driving module 30 can realize the driving of the calibration group 20 and ensure the calibration accuracy.

[0040] Specifically, both the X-axis module 31 and the Y-axis module 32 are linear motor driving modules 30. Using the linear motor driving module 30 as the X-axis module 31 and the Y-axis module 32 has high displacement accuracy, realizes the precise displacement of the calibration group 20, and further ensures the calibration accuracy of the electronic control actuator.

[0041] The calibration device of this embodiment further includes a bracket 40. The calibration platform 10 is connected to the bracket 40 through a shock absorber 50. The presence of the shock absorber 50 can greatly reduce the influence of vibration factors on the calibration platform 10 and ensure the calibration accuracy.

[0042] This embodiment also discloses a calibration method for a turbocharged electronic control actuator angle calibration device, including the following steps:

[0043] S1. Install the electronic control actuator to be calibrated into the centering chuck 111 to complete the positioning operation of the electronic control actuator. The centering chuck 111 is a three-jaw chuck to center the electronic control actuator.

[0044] S2. Under the action of the driving module 30, the pre-calibration sensor 21 performs a line scan on the electronic control actuator to determine the calibration position of the electronic control actuator. The pre-calibration sensor 21 uses a line scan sensor to scan the electronic control actuator before calibration. After obtaining the scan data, subsequent calibration operations are carried out.

[0045] S3. Under the action of the driving module 30, the calibration block 22 moves to the position to be calibrated of the electronic control actuator. The calibration cylinder 23 drives the calibration block 22 to calibrate the electronic control actuator. During the calibration process, after the calibration block 22 contacts the electronic control actuator, the calibration mark on the calibration block 22 calibrates the electronic control actuator.

[0046] In step S2 of this embodiment, it specifically includes the following steps:

[0047] S21. Under the action of the driving module 30, the pre-calibration sensor 21 performs an initial scan on the electronic control actuator, scanning to form m dividing lines and recording them. The m dividing lines can equally divide the electronic control actuator, facilitating the determination of subsequent calibration positions.

[0048] S22. The driving motor 60 drives the centering chuck 111 to rotate 90 degrees. The pre-calibration sensor 21 performs a secondary scan on the electronic control actuator, scanning to form n dividing lines and recording them. The n dividing lines will intersect with the m dividing lines, which is beneficial for subsequent calibration position confirmation.

[0049] S23. Determine the intersection positions of the m dividing lines and the n dividing lines, and the lines connected by the intersections are the positions to be calibrated for the electric control actuator.

[0050] In summary, with the combined action of the calibration platform 10, the calibration group 20, and the driving module 30, the present invention realizes the rapid calibration of the electric control actuator, without manual operation, greatly reducing the consumption of manpower, and can also effectively improve the calibration accuracy, meeting the actual use requirements of the electric control actuator. Moreover, the calibration method adopted by the present invention can partition the calibration positions of the electric control actuator, thereby ensuring the calibration accuracy.
