Description

Technical Field

[0001] The invention belongs to the technical field of industrial automation, and in particular relates to an actuator calibration device mechanism. Background Art

[0002] Among the traditional actuator calibration methods, manual calibration methods have significant defects, mainly concentrated in two aspects: low efficiency and poor accuracy. Manual calibration is not only cumbersome and time-consuming, but also requires the operator to adjust the various parameters of the actuator one by one, and conduct multiple trial runs and measurements, which leads to increased production line downtime and seriously restricts overall production efficiency. In addition, manual calibration is highly dependent on the operator's experience and skill level, and the calibration differences between different operators may be large. At the same time, human factors such as fatigue and distraction may also lead to unstable and inaccurate calibration results. Especially in situations where high precision and frequent adjustments are required, the limitations of manual calibration are more obvious, and it is difficult to meet the high requirements of modern industrial automation production for precision and efficiency. Therefore, the development and application of more efficient and accurate automated calibration technologies, such as actuator calibration systems based on angle calibration, has become an important trend to promote the upgrading of industrial automation. Summary of the invention

[0007] Preferably, the overall shape of the support frame is "冂"-shaped. Both sides of the bottom end of the support frame are fixedly installed on the top of the working panel through bolts, and slide rails for the clamping assembly to slide and move are arranged on both sides of the top of the support frame.

[0008] Preferably, the clamping assembly includes a clamping cylinder fixedly installed on the top of the support frame and a clamping plate slidably installed on the top of the support frame. Both the clamping plate and the clamping cylinder are two, and are symmetrically distributed on the left and right sides of the top of the support frame.

[0012] The beneficial effects of the present invention are as follows:

[0013] The actuator automatic calibration system based on angle calibration proposed by the present invention brings significant beneficial effects compared with the traditional manual calibration method, which are mainly reflected in the following aspects:

[0014] Significantly improve the calibration efficiency: The automatic calibration process integrates precision control components such as servo motors, cylinders, and sensors to realize the full automation of the actuator calibration. This process greatly reduces manual intervention, avoids cumbersome manual adjustment and multiple trial runs, significantly shortens the calibration cycle, reduces the production line downtime, and thus improves the overall production efficiency.

[0015] Enhance the calibration accuracy: The automatic calibration system relies on precise servo motors and sensor components to accurately control key parameters such as the contact force, rotation angle, and torque between the calibration head and the actuator, effectively eliminating the influence of human factors (such as fatigue, experience differences, etc.) on the calibration results, ensuring the consistency and accuracy of the calibration data, and meeting the requirements of high-precision calibration for modern industrial automation.

[0016] Reduced operational difficulty and skill requirements: Traditional manual calibration is highly dependent on the operator's experience and skill level, while the automated calibration system achieves standardization and intelligence of the calibration process through preset programs and algorithms, which reduces the skill requirements for operators, reduces training costs, and makes calibration work easier to manage and execute.

[0017] Improve production flexibility and adaptability: The automated calibration system can easily adapt to the calibration requirements of actuators of different models and specifications. Rapid switching can be achieved by adjusting program parameters, which enhances the flexibility and adaptability of the production line, helping companies to quickly respond to market changes and meet diversified production needs.

[0018] Improve production safety: During the automated calibration process, operators only need to operate under monitoring, which reduces direct contact with high-speed rotating parts and reduces the risk of work-related injuries. At the same time, the system's built-in safety protection measures (such as limit switches, overload protection, etc.) further ensure safety during the production process.

[0019] Optimize quality control and management: The automated calibration system can record all data during the calibration process in real time, providing a reliable basis for quality traceability. At the same time, through data analysis, potential quality problems can be discovered in a timely manner, providing strong support for the optimization and improvement of production processes, thereby continuously improving product quality and corporate competitiveness.

[0020] The actuator automatic calibration system based on angle calibration proposed in this scheme has brought significant beneficial effects to industrial automation production by improving calibration efficiency, accuracy, flexibility and safety, and optimizing quality control and management. It is an important technical means to promote the upgrading of industrial automation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, an embodiment of the present invention provides an actuator calibration equipment mechanism, including a working panel 1, a main bracket 2 is fixedly installed on the right end of the top of the working panel 1, a calibration component 3 is movably installed on the front above the main bracket 2, a downward pressure cylinder 9 is fixedly installed on the top of the main bracket 2, the output end of the downward pressure cylinder 9 is connected to the calibration component 3, a marking component 4 is installed on the bottom end of the calibration component 3, a support frame 5 located directly below the calibration component 3 is fixedly installed on the top of the working panel 1, a clamping component 7 is fixedly arranged on the top of the support frame 5, a tray component 8 is clamped and placed in the middle of the clamping component 7, a lifting cylinder 6 is fixedly arranged on the bottom end of the working panel 1, and the upper end of the output shaft of the lifting cylinder 6 extends upward to the interior of the support frame 5 and pushes and contacts with the bottom end of the tray component 8.

[0031] When the staff calibrates the actuator 20, after fixing the actuator 20 to be calibrated on the tray assembly 8, the staff starts the downward pressure cylinder 9. Due to the operation of the downward pressure cylinder 9, the calibration assembly 3 will be driven to move downward as a whole, so that the calibration head 24 is precisely in contact with the surface of the actuator 20 and is located above the spline drive hole 21. Then the servo motor 10 is started. Due to the operation of the servo motor 10, the calibration head 24 will be driven to rotate. When the calibration head 24 is rotated to align with the spline drive hole 21, due to the downward pressure of the downward pressure cylinder 9, the calibration head 24 smoothly enters the interior of the spline drive hole 21. Then, with the participation of the torque assembly 11 and the sensor assembly 12, the servo motor 10 continues to drive the calibration rod 13 to rotate, and the spline drive hole 21 is driven to rotate in the opposite direction through the calibration head 24 until it rotates to the upper limit. After that, the spline drive hole 21 is continued to be driven by the calibration head 24 to rotate forward, rotate to the lower limit, and then finally the calibration head 24 drives the spline drive hole 21 to rotate to the set initial use position; then the reciprocating cylinder 19 is started, and the reciprocating cylinder 19 drives the marking pen 14 and the marking pen 2 15 to contact the actuator 20, and the contact position between the actuator 20 and the marking pen 14 and the marking pen 2 15 is marked. After the marking is completed, the marking pen 14 and the marking pen 2 15 are reset by the reciprocating cylinder 19. At this time, the calibration is completed, and the clamping cylinder 17 is started. Under the action of the clamping cylinder 17, the clamps 16 on both sides are moved away from each other on the slide rail, and then the pallet 25 is released. At this time, under the action of the lifting cylinder 18, the pallet 25 is returned downward to the linear module and released to the next process.

[0032] Among them, the calibration component 3 includes a sliding vertical plate 23 movably installed on the front side of the main bracket 2, the output shaft of the downward pressure cylinder 9 is fixedly connected to the sliding vertical plate 23, a servo motor 10 is fixedly installed on the top of the front side of the sliding vertical plate 23, the output shaft of the servo motor 10 is fixedly installed downwardly with a torque component 11, a sensor component 12 and a calibration rod 13 in sequence, and a calibration head 24 is fixedly installed at the bottom end of the calibration rod 13.

[0033] By starting the downward pressure cylinder 9, the operation of the downward pressure cylinder 9 will drive the calibration component 3 to move downward as a whole, including the servo motor 10, the torque component 11, the sensor component 12, the calibration rod 13 and the calibration head 24 to move downward together, so as to make the calibration head 24 contact with the actuator 20, and then the servo motor 10 will synchronously drive the torque component 11, the sensor component 12, the calibration rod 13 and the calibration head 24 to rotate, so that the calibration head 24 is aligned with the spline drive hole 21, and then drive the actuator 20 to rotate to realize the calibration operation.

[0034] Among them, the marking component 4 includes reciprocating cylinders 19 fixedly installed on both sides of the bottom end of the calibration component 3 as a whole. The number of the reciprocating cylinders 19 is two. A marking pen one 14 and a marking pen two 15 are respectively and fixedly installed at the output ends of the two reciprocating cylinders 19; the marking pen one 14 and the marking pen two 15 are on the same horizontal line.

[0035] The staff starts the reciprocating cylinder 19. The operation of the reciprocating cylinder 19 drives the marking pen one 14 and the marking pen two 15 to contact the actuator 20, and marks the contact positions of the actuator 20 with the marking pen one 14 and the marking pen two 15. After the marking is completed, through the retraction movement of the reciprocating cylinder 19, the marking pen one 14 and the marking pen two 15 are driven to reset.

[0036] Among them, the support frame 5 as a whole presents a "冂" shape. Both sides of the bottom end of the support frame 5 are fixedly installed on the top of the working panel 1 through bolts. Slide rails for the sliding movement of the clamping component 7 are provided on both sides of the top of the support frame 5.

[0037] Due to the shape design of the support frame 5, while the clamping component 7 can be supported, the two groups of clamping components 7 are symmetrically distributed on the top of the support frame 5, and at the same time, space can be provided for the installation of the lifting cylinder 6.

[0038] Among them, the clamping component 7 includes a clamping cylinder 17 fixedly installed on the top of the support frame 5 and a clamping plate 16 slidably installed on the top of the support frame 5. There are two clamping cylinders 17 and two clamping plates 16, and they are symmetrically distributed on the left and right sides of the top of the support frame 5.

[0039] When calibration operation is required, the actuator is fixed to a suitable position, and then the clamping cylinder 17 is started. Due to the operation of the clamping cylinder 17, the two clamping plates 16 will be driven to move closer inward at the same time, so as to contact the tray 25. Then, when the calibration operation is completed, the clamping cylinder 17 is started again. Under the action of the clamping cylinder 17, the two clamping plates 16 on both sides move away from each other outward on the slide rail, so as to release the positioning of the tray 25. At this time, under the action of the lifting cylinder 18, the tray 25 moves downward to the linear module and is released to the next process.

[0040] Among them, the tray component 8 includes a tray 25 clamped between the two clamping plates 16. An actuator 20 is placed on the top of the tray 25, and a spline drive hole 21 is provided on the surface of the actuator 20.

[0041] Among them, the torque component 11 outputs positive and negative torque signals, can measure static torque and rotational torque; it has high precision, stable and reliable performance, can operate at high speed for a long time, and both ends are key-connected. The maximum rotational speed does not exceed 3000 revolutions per minute.

[0042] Among them, a fixed vertical plate 22 located at the back of the calibration component 3 is fixedly installed on the front of the main bracket 2, and a sliding vertical plate 23 is movably installed on the front of the fixed vertical plate 22. The fixed vertical plate 22 is movably connected to the calibration component 3.

[0043] Due to the functions of the fixed vertical plate 22 and the sliding vertical plate 23, the calibration component 3 will be more stable during the lifting movement, thereby improving the stability and accuracy of the lifting of the device.

[0044] Working principle and usage process:

[0045] When the staff calibrates the actuator 20, after fixing the actuator 20 to be calibrated on the tray assembly 8, the staff starts the downward pressure cylinder 9. Due to the operation of the downward pressure cylinder 9, the calibration assembly 3 will be driven to move downward as a whole, so that the calibration head 24 is precisely in contact with the surface of the actuator 20 and is located above the spline drive hole 21. Then the servo motor 10 is started. Due to the operation of the servo motor 10, the calibration head 24 will be driven to rotate. When the calibration head 24 is rotated to align with the spline drive hole 21, due to the downward pressure of the downward pressure cylinder 9, the calibration head 24 smoothly enters the interior of the spline drive hole 21. Then, with the participation of the torque assembly 11 and the sensor assembly 12, the servo motor 10 continues to drive the calibration rod 13 to rotate, and the spline drive hole 21 is driven to rotate in the opposite direction through the calibration head 24 until it rotates to the upper limit. After that, the spline drive hole 21 is continued to be driven by the calibration head 24 to rotate forward, rotate to the lower limit, and then finally the calibration head 24 drives the spline drive hole 21 to rotate to the set initial use position; then the reciprocating cylinder 19 is started, and the reciprocating cylinder 19 drives the marking pen 14 and the marking pen 2 15 to contact the actuator 20, and the contact position between the actuator 20 and the marking pen 14 and the marking pen 2 15 is marked. After the marking is completed, the marking pen 14 and the marking pen 2 15 are reset by the reciprocating cylinder 19. At this time, the calibration is completed, and the clamping cylinder 17 is started. Under the action of the clamping cylinder 17, the clamps 16 on both sides are moved away from each other on the slide rail, and then the pallet 25 is released. At this time, under the action of the lifting cylinder 18, the pallet 25 is returned downward to the linear module and released to the next process.
