Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and particularly relates to a flexible polishing and grinding equipment for aluminum profiles and a control method thereof. Background Art

[0002] As a lightweight metal material widely used in modern industry, aluminum profiles have the advantages of high strength, good corrosion resistance, easy processing and forming, and good thermal and electrical conductivity. They are widely used in many fields such as construction, automotive, aerospace, machinery manufacturing, and electronics. Their diverse cross-sectional designs and excellent physical properties make aluminum profiles play an irreplaceable role in constructing structural components, heat dissipation elements, decorative parts, etc. However, in the production and processing of aluminum profiles, especially in the surface treatment process, there are extremely high requirements for their surface finish and accuracy.

[0003] In order to meet the high requirements for the surface quality of aluminum profiles, the polishing and grinding process has become an indispensable part. Polishing and grinding can not only remove burrs, scratches, and oxide layers on the surface of aluminum profiles, but also improve their surface finish and flatness through fine grinding treatment, enhancing the aesthetics and corrosion resistance of the products. However, with the increasing market demand for diversified and customized aluminum profiles, the traditional polishing and grinding methods are difficult to meet the requirements of efficient and precise processing. Therefore, the flexible polishing and grinding technology has emerged.

[0004] However, in the existing polishing and grinding equipment, the adjustment process of the upper and lower, left and right grinding wheels relies too much on manual observation and handwheel adjustment, resulting in long adjustment time and inaccurate positions, thus affecting the grinding effect. At the same time, during the polishing process, due to minute deformations and slight dimensional differences, the volatility of the grinding quality is further exacerbated. Summary of the Invention

[0041] Please refer to Figure 3 , Another embodiment of the present invention also lies in providing a control method for an aluminum profile flexible polishing and grinding device, which is applied to the aluminum profile flexible polishing and grinding device as described above, and includes the following steps:

[0042] S1. The feeding device 2 operates, and the aluminum profile moves forward with the feeding device 2. When the aluminum profile moves to the position of the upper and lower grinding mechanisms 4, the operation of the feeding device 2 is stopped, and the clamping mechanism 3 clamps the aluminum profile to fix the position of the aluminum profile.

[0043] S2. The upper and lower grinding mechanisms 4 start to work. The lifting structure 43 drives the upper grinding assembly 41 and the lower grinding assembly 42 to approach and contact the upper and lower surfaces of the aluminum profile respectively. When the torque sensor in the upper grinding assembly 41 receives that the torque of the upper grinding assembly 41 reaches the preset value, it indicates that the contact pressure between the upper grinding assembly 41 and the aluminum profile is appropriate, and then starts grinding. When the torque sensor in the lower grinding assembly 42 receives that the torque of the lower grinding assembly 42 reaches the preset value, it indicates that the contact pressure between the lower grinding assembly 42 and the aluminum profile is appropriate, and then starts grinding. At the same time, the torque sensor monitors the torque change during the grinding process in real time and adjusts the grinding force and speed as needed. The whole process realizes the constant force in the grinding process through the PID (Proportional-Integral-Differential) control algorithm by collecting real-time dynamic torque feedback, so as to ensure the grinding effect. The automatic control reduces manual intervention and improves production efficiency.

[0044] S3. After grinding is completed, loosen the clamping mechanism 3, and continue to start the feeding device 2. When the aluminum profile moves to the position of the left and right grinding mechanisms 5, stop the operation of the feeding device 2, and the clamping mechanism 3 clamps the aluminum profile to fix its position.

[0045] S4. The left and right grinding mechanisms 5 start to work. The translation structure 53 drives the left grinding assembly 51 and the right grinding assembly 52 to approach and contact the left and right surfaces of the aluminum profile respectively. When the torque sensor in the left grinding assembly 51 receives that the torque of the left grinding assembly 51 reaches the preset value, it indicates that the contact pressure between the left grinding assembly 51 and the aluminum profile is appropriate, and then starts grinding. When the torque sensor in the right grinding assembly 52 receives that the torque of the right grinding assembly 52 reaches the preset value, it indicates that the contact pressure between the right grinding assembly 52 and the aluminum profile is appropriate, and then starts grinding. At the same time, the torque sensor monitors the torque change during the grinding process in real time and adjusts the grinding force and speed as needed. The whole process realizes the constant force in the grinding process through the PID (Proportional-Integral-Differential) control algorithm by collecting real-time dynamic torque feedback, so as to ensure the grinding effect. The automatic control reduces manual intervention and improves production efficiency.

[0046] S5. After the aluminum profile is completely ground, loosen the clamping mechanism 3 and send it out of the equipment by the feeding device 2.

[0047] As a preferred embodiment of the present invention, it may also have the following additional technical features: An aluminum profile detection sensor is provided on the feeding device 2 to identify the position of the aluminum profile at the upper and lower grinding mechanisms 4 and the left and right grinding mechanisms 5, ensuring that it is at the best grinding starting point before entering the upper and lower grinding mechanisms 4 and the left and right grinding mechanisms 5, which helps to improve the accuracy and consistency of grinding. In addition, in other embodiments, the aluminum profile detection sensor can be an optoelectronic sensor, a laser sensor, an electromagnetic sensor, an image sensor, etc., which are not specifically limited here.

[0048] In addition, a torque sensor is a device that can directly measure the torque on the motor shaft, usually measuring the magnitude of the torque through strain gauges or the magnetoelastic effect. When the motor shaft is subjected to torque, the strain gauges or magnetoelastic materials inside the sensor will deform, thereby changing their physical properties such as resistance or magnetic permeability. These changes can be converted into electrical signals and transmitted to the control system for processing. The measured torque feedback values will all be transmitted to the control system and compared with the target contact force. The control system will adjust the output of the motor according to the magnitude and direction of the deviation through the PID control algorithm or other control strategies to reduce the deviation and maintain the constancy of the force during the grinding process.

[0049] The structural design of the flexible polishing and grinding equipment for aluminum profiles in this embodiment is reasonable and convenient to use. For other equipment with similar usage requirements, this structure can also be adopted to achieve the same purpose. In this embodiment, the flexible polishing and grinding equipment for aluminum profiles realizes the efficient and precise grinding of aluminum profiles. By real-time monitoring of torque changes and adjusting the grinding force and speed, the consistency and stability of the grinding quality are ensured.
