Description

Technical Field

[0001] This utility model belongs to the field of correction equipment technology, specifically referring to an angle turntable alignment and correction mechanism. Background Technology

[0002] In machining processes (such as drilling and milling of precision parts) or automated assembly, it is often necessary to use an angle turntable to rotate the workpiece to a designated angle position for operation. Existing angle turntables mostly rely on motor drives and encoder positioning. Although they can achieve basic angle adjustment, after long-term use, factors such as mechanical transmission clearance (such as gear meshing clearance, coupling wear), load changes, or vibration can cause deviations between the actual stopping angle of the turntable and the preset angle (typically within the range of 0.1°-0.5°). Furthermore, existing equipment lacks real-time detection and dynamic correction functions, requiring manual periodic calibration, which not only increases operating costs but also easily leads to decreased workpiece machining accuracy and increased scrap rate due to alignment errors, making it difficult to meet the needs of high-precision production scenarios. Utility Model Content

[0003] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model proposes an angle turntable alignment and correction mechanism, which effectively solves the problem that the angle turntable alignment and correction mechanism lacks real-time detection and dynamic correction functions, making it difficult to meet the usage requirements of high-precision production scenarios.

[0004] The technical solution adopted by this utility model is as follows: The present utility model proposes an angle turntable alignment and correction mechanism, including a base, a support platform on the base, a turntable drive assembly on the base, an angle detection assembly on the support platform, and a correction control module on the support platform.

[0005] Preferably, the turntable drive assembly includes a fixed base fixedly mounted on the base, a drive motor mounted on the fixed base, a gearbox mounted on the output shaft of the drive motor and fixedly mounted on the base, and a rotating shaft mounted at the output end of the gearbox.

[0006] To better achieve the effects of angle detection and deviation recognition, the angle detection component includes a support frame fixedly mounted on the carrier platform, a scale code disk rotatably mounted on the support frame and fixedly mounted on the rotation axis, a fixed frame fixedly mounted below the carrier platform, and a laser displacement sensor fixedly mounted on the fixed frame.

[0007] To achieve dynamic correction more quickly, the correction control module includes a correction controller fixedly mounted on the support platform. The correction controller is powered on and connected to a PLC controller, a signal processor, and a PID regulator.

[0008] Furthermore, the drive motor is a servo motor, whose built-in encoder can provide real-time feedback of the rotation angle and supports pulse signal adjustment by the correction controller. The detection end of the laser displacement sensor faces the scale code disk, which can collect information from the scale code disk in real time and transmit it to the signal processor.

[0009] To achieve the correction effect, the signal processor can convert the analog signal collected by the laser displacement sensor into a digital signal, the correction controller can calculate the difference between the actual angle signal and the preset angle signal, and generate a compensation pulse command to send to the drive motor, and the PID regulator can dynamically adjust the compensation speed and rotation direction of the drive motor according to the magnitude of the deviation value to ensure that the scale encoder rotates to the target angle.

[0010] The beneficial effects of this utility model using the above structure are as follows: The angle turntable alignment and correction mechanism proposed in this solution collects the actual angle of the carrying turntable in real time through the angle detection component, and the correction control module compares the deviation between the actual angle and the preset angle; the correction control module immediately sends a compensation command to the turntable drive component, and achieves dynamic correction through precise adjustment of the drive motor without manual intervention; at the same time, the drive motor and gearbox, combined with the PID regulator, can effectively reduce the impact of mechanical backlash on the correction accuracy, improve the overall alignment accuracy, and are suitable for high-precision machining and assembly scenarios, reduce the workpiece scrap rate, and improve production efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes an angle turntable alignment and correction mechanism, which includes a base 1, a support platform 2 on the base 1, a turntable drive assembly 3 on the base 1, an angle detection assembly 4 on the support platform 2, and a correction control module 5 on the support platform 2.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, the turntable drive assembly 3 includes a fixed base 6 fixedly mounted on the base 1, a drive motor 7 mounted on the fixed base 6, a gearbox 8 mounted on the output shaft of the drive motor 7 and fixedly mounted on the base 1, and a rotating shaft 9 mounted on the output end of the gearbox 8.

[0017] like Figure 2 , Figure 3 and Figure 4 As shown, the angle detection component 4 includes a support frame 10 fixedly mounted on the support platform 2. A scale code disk 11 is rotatably mounted on the support frame 10 and fixedly mounted on the rotation shaft 9. A fixed frame 12 is fixedly mounted below the support platform 2, and a laser displacement sensor 13 is fixedly mounted on the fixed frame 12.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the correction control module 5 includes a correction controller 14 fixedly mounted on the support platform 2. The drive motor 7 is a servo motor with its built-in encoder that can provide real-time feedback of the rotation angle and supports pulse signal adjustment of the correction controller 14. The correction controller 14 is powered on and connected to a PLC controller 15 and a signal processor 16. The detection end of the laser displacement sensor 13 faces the scale code disk 11, which can collect information from the scale code disk 11 in real time and transmit it to the signal processor 16. The correction controller 14 is powered on and connected to a PID regulator 17. The signal processor 16 can convert the analog signal collected by the laser displacement sensor 13 into a digital signal. The correction controller 14 can calculate the difference between the actual angle signal and the preset angle signal and generate a compensation pulse command to send to the drive motor 7. The PID regulator 17 can dynamically adjust the compensation speed and rotation direction of the drive motor 7 according to the magnitude of the deviation value to ensure that the scale code disk 11 rotates to the target angle.

[0019] In practical use, the user inputs a preset angle value to the PLC controller 15 of the correction control module 5 through an external terminal. The PLC controller 15 sends a rotation command to the drive motor 7. After the drive motor 7 is changed speed by the gearbox 8, it drives the scale encoder 11 on the rotating shaft 9 to rotate. During the rotation of the scale encoder 11, the laser displacement sensor 13 of the angle detection component 4 collects the scale information of the scale encoder 11 in real time and transmits the analog signal to the signal processor 16. The signal processor 16 converts the analog signal into a digital angle signal and sends it to the correction controller 14. The correction controller 14 compares the actual angle signal with the preset angle signal. If the deviation value is ≤0.01°, the drive motor 7 stops and the scale encoder 11 completes the alignment. If the deviation value is >0.01°, the correction controller 14 generates a compensation command, which is optimized by the PID regulator 17 and sent to the drive motor 7. The drive motor 7 drives the scale encoder 11 to fine-tune to the target angle, completing the alignment correction.
