Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a flexible polishing and grinding equipment for aluminum profiles and its control method. Background Technology

[0002] Aluminum profiles, as a lightweight metal material widely used in modern industry, possess advantages such as high strength, good corrosion resistance, easy processing and forming, and good thermal and electrical conductivity. They are widely used in construction, automotive, aerospace, machinery manufacturing, and electronics, among other fields. Their diverse cross-sectional designs and excellent physical properties make aluminum profiles irreplaceable in constructing structural components, heat dissipation elements, and decorative parts. However, the production and processing of aluminum profiles, especially in the surface treatment stage, places extremely high demands on surface finish and precision.

[0003] To meet the high requirements for the surface quality of aluminum profiles, polishing and grinding have become an indispensable step. Polishing and grinding not only remove burrs, scratches, and oxide layers from the surface of aluminum profiles, but also improve surface smoothness and flatness through fine grinding, enhancing the product's aesthetics and corrosion resistance. However, with the increasing market demand for diversified and customized aluminum profiles, traditional polishing and grinding methods are no longer sufficient to meet the needs of efficient and precise processing. Therefore, flexible polishing and grinding technology has emerged.

[0004] However, in existing polishing and grinding equipment, the adjustment process of the up and down and left and right grinding wheels relies too much on manual observation and handwheel adjustment, resulting in long adjustment time and inaccurate positioning, which affects the grinding effect. At the same time, due to slight deformation and minor dimensional differences during the polishing process, the fluctuation of grinding quality is further aggravated. Summary of the Invention

[0014] Another object of the present invention is to provide a control method for a flexible polishing and grinding equipment for aluminum profiles, applicable to the aforementioned flexible polishing and grinding equipment for aluminum profiles, comprising the following steps:

[0015] When the feeding device is running, the aluminum profile moves forward with the feeding device. When the aluminum profile moves to the position of the upper and lower grinding mechanism, the feeding device stops running and the clamping mechanism clamps the aluminum profile to fix its position.

[0016] The upper and lower grinding mechanisms start working, and the lifting structure drives the upper grinding component and the lower grinding component to approach and contact the upper and lower surfaces of the aluminum profile, respectively; when the torque sensor in the upper grinding component receives the torque of the upper grinding component reaching the preset value, grinding begins; when the torque sensor in the lower grinding component receives the torque of the lower grinding component reaching the preset value, grinding begins.

The transfer roller 25 is rotatably connected to the roller frame 26. The roller frame 26 is fixedly connected to the support structure 1. When it is necessary to convey materials, the feeding motor 21 is started, and the output end of the feeding motor 21 begins to rotate, driving the main rotating wheel 23 fixedly connected to it to rotate together. As the main rotating wheel 23 rotates, the rotating shaft 22 begins to move, transmitting power from the main rotating wheel 23 to the auxiliary rotating wheel 24. The auxiliary rotating wheel 24 rotates under the drive of the rotating shaft 22, thereby driving the transfer roller 25 connected to it to rotate. The transfer roller 25 is fixedly connected to the support structure 1 via the roller frame 26 to ensure its stability during rotation. When the transfer roller 25 rotates, the aluminum profile on its surface is driven forward. In this embodiment, four transfer rollers 25 are provided, and correspondingly, a roller frame 26 matches the transfer roller 25. The upper and lower grinding mechanism 4 is located between the second and third transfer rollers 25, and the left and right grinding mechanism 5 is located between the third and fourth transfer rollers 25. Each transfer roller 25 is connected to a set of rotating wheels 24. Please refer to... Figure 2 For example, the second transfer roller 25 is connected to a secondary roller a241. At this time, the secondary roller a241 is connected to another secondary roller b242 through a rotating rod 245 to form a power transmission unit. The third transfer roller 25 is connected to its corresponding secondary roller c243. The drive belt 244 is sleeved on the secondary rollers b242 and c243 to ensure continuous power transmission.

[0034] As a preferred embodiment of the present invention, it may also have the following additional technical features: a pressing mechanism 27 is provided on the roller frame 26.

For aluminum profiles of different sizes or shapes, the processing requirements can be met by adjusting the position or clamping force of the clamping mechanism 3.

[0036] As a preferred embodiment of the present invention, it may also have the following additional technical features: the upper grinding assembly 41 includes an upper servo motor 411, an upper grinding wheel 412, an upper rotating rod 413 and an upper sliding seat 414.

When the upper servo motor 411 starts, the power it generates is transmitted to the upper rotating rod 413 through the first drive structure, which in turn drives the upper grinding wheel 412 to rotate at high speed. By controlling the lifting structure 43, the upper sliding seat 414 can be moved up and down precisely, thereby driving the upper grinding wheel 412 to move closer to or away from the surface of the aluminum profile to be ground. The position of the upper grinding wheel 412 is adjusted by the lifting structure 43 and the upper sliding seat 414.

The output torque of the lower servo motor is monitored by the torque sensor to achieve automatic adjustment of the effective force contact between the lower grinding wheel and the lower surface of the aluminum profile. The torque sensor feeds the data back to the control system, and the control system adjusts the speed and direction of the lower servo motor to adapt to different grinding requirements and workpiece materials.

[0041] Please see Figure 3 Another embodiment of the present invention provides a control method for a flexible polishing and grinding equipment for aluminum profiles, applied to the flexible polishing and grinding equipment for aluminum profiles as described above, comprising 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 mechanism 4, the operation of the feeding device 2 is stopped, and the clamping mechanism 3 clamps the aluminum profile to fix its position.

[0043] S2. The upper and lower grinding mechanisms 4 begin operation. The lifting structure 43 drives the upper grinding component 41 and the lower grinding component 42 to approach and contact the upper and lower surfaces of the aluminum profile, respectively. When the torque sensor in the upper grinding component 41 receives a preset value indicating that the torque of the upper grinding component 41 reaches the preset value, it indicates that the contact pressure between the upper grinding component 41 and the aluminum profile is appropriate, and grinding begins. Similarly, when the torque sensor in the lower grinding component 42 receives a preset value indicating that the contact pressure between the lower grinding component 42 and the aluminum profile is appropriate, grinding begins. Simultaneously, the torque sensor monitors the torque changes during the grinding process in real time and adjusts the grinding force and speed as needed. The entire process uses a PID (proportional-integral-derivative) control algorithm based on real-time dynamic torque feedback to maintain constant force during grinding, thereby ensuring the grinding effect. Automated control reduces manual intervention and improves production efficiency.

[0044] S3. After grinding is completed, release the clamping mechanism 3, continue to start the feeding device 2, and 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 begin operation. The translation structure 53 drives the left grinding component 51 and the right grinding component 52 to approach and contact the left and right surfaces of the aluminum profile, respectively. When the torque sensor in the left grinding component 51 receives a preset value indicating that the torque of the left grinding component 51 reaches the preset value, it indicates that the contact pressure between the left grinding component 51 and the aluminum profile is appropriate, and grinding begins. When the torque sensor in the right grinding component 52 receives a preset value indicating that the contact pressure between the right grinding component 52 and the aluminum profile is appropriate, grinding begins. Simultaneously, the torque sensor monitors the torque changes during the grinding process in real time and adjusts the grinding force and speed as needed. The entire process uses a PID (proportional-integral-derivative) control algorithm based on real-time dynamic torque feedback to maintain constant force during grinding, thereby ensuring the grinding effect. Automated control reduces manual intervention and improves production efficiency.

[0046] S5. After the aluminum profile is completely polished, the clamping mechanism 3 is released and the material is fed 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 mechanism 4 and the left and right grinding mechanism 5, ensuring that it is at the optimal grinding starting point before entering the upper and lower grinding mechanism 4 and the left and right grinding mechanism 5, which helps to improve the accuracy and consistency of grinding. In addition, in other embodiments, the aluminum profile detection sensor may be a photoelectric sensor, a laser sensor, an electromagnetic sensor, an image sensor, etc., which are not specifically limited here.

[0048] Furthermore, a torque sensor is a device that can directly measure the torque on a motor shaft, typically using strain gauges or magnetoelastic effects to measure the magnitude of the torque. When the motor shaft is subjected to torque, the strain gauge or magnetoelastic material inside the sensor deforms, thereby changing its physical properties such as resistance or permeability. These changes can be converted into electrical signals and transmitted to the control system for processing. The measured torque feedback values ​​are transmitted to the control system and compared with the target contact force. The control system adjusts the motor output based on the magnitude and direction of the deviation using PID control algorithms or other control strategies to reduce the deviation and maintain a constant force during the grinding process.
