Description

Technical Field

[0001] The present application relates to the field of profile processing equipment, and in particular to an automatic profile grinding machine. Background Art

[0002] An automatic profile grinding machine is a device dedicated to grinding and polishing the surfaces of various profiles (such as aluminum profiles, steel profiles, plastic-steel profiles, etc.). It automatically grinds the surface of the profile mechanically to make its surface smooth and flat to meet the requirements of subsequent painting or assembly. This device is widely used in fields such as door and window manufacturing, building profiles, and the automotive industry. With the growth of market demand and the progress of technology, the demand for improving production efficiency and processing quality is becoming increasingly urgent, and the application scope of the automatic profile grinding machine is also constantly expanding. Currently, the common profile grinding equipment on the market mainly adopts a fixed grinding head and a manual adjustment method. Specifically, these devices usually include a fixed bracket and a grinding tool installed thereon, such as a grinding wheel or a grinding belt. The operator needs to manually place the profile on the workbench and manually adjust the position of the grinding head to achieve grinding at different positions. In addition, some devices with a higher degree of automation adopt an electrically driven grinding head, but still lack a flexible adjustment mechanism and cannot adapt to profiles of different types and sizes. However, these existing grinding devices have some obvious deficiencies. Since the parallelism and weld height of each position of the profile are not exactly the same, using a fixed grinding head easily leads to situations where the grinding is not in place or excessive, which will not only affect the surface quality and aesthetics of the profile, but also increase the subsequent repair cost and reduce the overall quality of the product. Summary of the Invention

[0003] In order to further improve the effect of grinding the profile weld, the present application provides an automatic profile grinding machine.

[0004] The automatic profile grinding machine provided by the present application adopts the following technical solutions: An automatic profile grinding machine includes a frame and a grinding belt. The grinding belt is installed on the frame through a driving mechanism. The driving mechanism can drive the grinding belt to grind the profile. A horizontal adjustment device is installed on the frame, a rotation adjustment device is installed on the horizontal adjustment device, and a mounting seat is provided on the rotation adjustment device. The angle of the mounting seat is adjusted through the rotation adjustment device. A clamping and fixing member is provided on the mounting seat, and the clamping and fixing member is used for fixedly installing the profile.

[0005] By adopting the above technical solutions, the combined use of the horizontal adjustment device and the rotary adjustment device can precisely adjust the angle and parallelism of the mounting seat, ensuring that the grinding belt can apply force evenly in multiple directions, avoiding problems such as insufficient grinding or excessive grinding caused by differences in parallelism and weld height at various positions of the profile; the highly automated design reduces manual intervention. The operator only needs to fix the profile on the clamping fixture, and the rest of the work is completed by the machine, greatly shortening the processing time and improving production efficiency; through the combined application of the rotary adjustment device and the horizontal adjustment device, the equipment can adapt to profiles of various shapes and sizes without frequently replacing the grinding head or readjusting the equipment, thus expanding the application range of the equipment; the uniform movement and multi-directional adjustment ability of the grinding belt ensure the smoothness and flatness of the profile surface, improving the appearance quality and overall quality of the product and reducing the later repair cost.

[0006] In a specific feasible implementation, the driving device includes a driving motor, a linkage belt, and guide rollers. The driving motor is installed on the frame. There are several guide rollers, and several guide rollers are rotatably connected to the frame. The grinding belts are jointly sleeved on the guide rollers. The linkage belt is jointly sleeved on the output shaft of the driving motor and one of the guide rollers. The driving motor drives the guide rollers to rotate through the linkage belt.

[0007] By adopting the above technical solutions, the installation of the driving motor on the frame ensures the reliability and stability of the power source; the setting of multiple guide rollers enables the grinding belts to be evenly stressed at multiple points, avoiding local wear and slipping phenomena and extending the service life of the grinding belts; the linkage belt connects the output shaft of the driving motor and one of the guide rollers, realizing efficient power transmission, reducing energy loss, and ensuring the consistency of the grinding speed. In a specific feasible implementation, the horizontal adjustment device includes a support plate, a horizontal adjustment motor, and a limit rack. Rollers are installed on both sides of the lower plate surface of the support plate. Corresponding slide rails are provided on the frame, and the rollers are rollingly connected to the slide rails. The limit rack is installed on one of the slide rails. The horizontal adjustment motor is installed on the lower plate surface of the support plate, and an adjustment gear is installed on the output shaft of the horizontal adjustment motor. The adjustment gear is meshed with the limit rack.

[0008] By adopting the above technical solution, the horizontal adjustment device can achieve precise horizontal position adjustment of the profile during the grinding process. Specifically, the rollers installed on both sides of the lower plate surface of the support plate can roll on the slide rails on the frame, ensuring the stable operation of the entire device. At the same time, the adjustment gear on the output shaft of the horizontal adjustment motor is meshed with the limit rack, so that the horizontal adjustment motor can drive the adjustment gear to move on the limit rack, thereby achieving precise horizontal movement of the support plate and various components installed thereon. This design not only improves the precision of profile grinding, but also enhances the flexibility and adaptability of the equipment, can better handle profiles of different sizes and shapes, and improves the grinding effect and production efficiency.

[0009] In a specific feasible implementation, the rotation adjustment device includes a rotation adjustment motor and a rotating plate. The rotation adjustment motor is installed on the lower plate surface of the support plate. The output shaft of the rotation motor penetrates through the support plate and extends towards the upper plate surface. The rotating plate is installed at one end of the output shaft of the rotation motor extending to the upper plate surface of the support plate, and the clamping and fixing member is installed on the upper plate surface of the rotating plate.

[0010] By adopting the above technical solution, the combination of the rotation adjustment motor and the rotating plate enables the clamping and fixing member to rotate freely within a certain range. This design not only improves the flexibility of the profile automatic grinding machine, but also can perform precise angle adjustment according to different types of profiles, ensuring a more uniform and efficient grinding process. Especially when processing profiles with complex shapes or special angles, this rotation function can significantly improve the grinding quality and effect, reduce manual intervention, and improve production efficiency.

[0011] In a specific feasible implementation, the clamping and fixing member includes a clamping seat, a clamping block, and a limit screw rod. The clamping seat is installed on the mounting seat. A chute is provided on the clamping seat. There are two clamping blocks, and the two clamping blocks are respectively slidably connected to both sides of the chute. The limit screw rod is rotatably connected to the clamping seat and penetrates through the chute along the length direction of the chute. The external thread spiral directions at both ends of the limit screw rod are opposite. The two clamping blocks are respectively driven and connected to both ends of the limit screw rod, and the two clamping blocks are driven to move in opposite directions by rotating the limit screw rod.

[0012] By adopting the above technical solution, the clamping and fixing member can achieve stable clamping of the profile. Specifically, the design of the chute on the clamping seat and the two clamping blocks enables the clamping blocks to slide along the chute, thereby adapting to profiles of different widths. The external thread spiral directions at both ends of the limit screw rod are opposite. When the limit screw rod rotates, the two clamping blocks will move in opposite directions synchronously, ensuring that the clamping force is evenly distributed and effectively preventing the profile from shifting or loosening during the grinding process. This design not only improves the grinding precision and stability, but also enhances the applicability and flexibility of the equipment, and is applicable to profiles of various specifications.

[0013] In a specific feasible embodiment, a circular groove is formed in the mounting base, and the clamping seat is slidably connected in the circular groove.

[0014] By adopting the above technical solution, the clamping seat can slide in the circular groove, thereby realizing accurate positioning and fixing of profiles with different diameters and shapes. This design improves the flexibility and application range of the equipment, enables the same equipment to adapt to various types of profiles, reduces the time for replacement and adjustment, and improves production efficiency. At the same time, this structure can also ensure the stability of the profile during the grinding process and avoid quality problems caused by position deviation.

[0015] In a specific feasible embodiment, at least two clamping and fixing members are provided, and they are slidably connected at different positions in the circular groove.

[0016] By adopting the above technical solution, at least two clamping and fixing members are provided and they are slidably connected at different positions in the circular groove. This design enables the profile to be firmly fixed at multiple positions simultaneously, improves the stability of the profile during the grinding process, avoids shaking or deviation caused by single-point fixing, and thus ensures the quality and accuracy of grinding. In addition, multi-point fixing can also adapt to profiles with different shapes and sizes, enhancing the applicability and flexibility of the equipment.

[0017] In a specific feasible embodiment, a magnetic suction seat and an electromagnet are further included. The electromagnet is installed at the bottom of the clamping seat, and the magnetic suction seat is installed in the circular groove. By energizing the electromagnet, it can be adsorbed on the magnetic suction seat.

[0018] By adopting the above technical solution, the electromagnet is installed at the bottom of the clamping seat, and the magnetic suction seat is installed in the circular groove. By energizing the electromagnet, it can be adsorbed on the magnetic suction seat, thereby ensuring the stability and reliability of the clamping and fixing member at different positions; this design not only improves the working efficiency of the profile automatic grinding machine, but also enhances the flexibility of the equipment, makes the operation more convenient, and reduces the time and labor intensity of manual intervention.

[0019] In a specific feasible embodiment, a grinding auxiliary device is further included. The grinding auxiliary device includes a lifting cylinder and an auxiliary plate. The lifting cylinder is installed on the frame above the clamping and fixing member, and the piston rod of the lifting cylinder faces the clamping and fixing member. The auxiliary plate is installed on the piston rod of the lifting cylinder, and the auxiliary plate is driven by the lifting cylinder to push the grinding belt to move.

[0020] By adopting the above technical solution, the lifting cylinder is installed on the frame above the clamping and fixing member, the piston rod is arranged towards the clamping and fixing member, and the auxiliary plate is installed on the piston rod of the lifting cylinder. When the profile needs to be polished, the lifting cylinder can drive the auxiliary plate to move downward through the piston rod, so that the auxiliary plate contacts and pushes the polishing belt against the surface of the profile, thereby ensuring uniform distribution of the pressure between the polishing belt and the profile and improving the polishing effect. This design can effectively avoid the problems of insufficient or excessive polishing caused by the loosening of the polishing belt, improve the flatness and smoothness of the profile surface, and further improve the overall quality and production efficiency of the product.

[0021] In a specific feasible embodiment, it further includes a monitoring mechanism and a central control box. The monitoring mechanism includes a mounting frame and an industrial camera. The mounting frame is installed on the frame, the industrial camera is installed at the upper end of the mounting frame, the industrial camera is arranged towards the angle adjustment device, the central control box is installed on the frame, and a control module is installed in the central control box. The control module is electrically connected to both the industrial camera and the angle adjustment device.

[0022] By adopting the above technical solution, the profile automatic polishing machine is added with a monitoring mechanism and a central control box. The industrial camera can monitor the working state of the angle adjustment device in real time to ensure the accurate position and posture of the profile during the polishing process. The control module receives the data collected by the industrial camera and dynamically adjusts the actions of the angle adjustment device according to these data, so as to achieve precise polishing of each part of the profile. This intelligent design improves the polishing accuracy and efficiency, reduces manual intervention, reduces errors caused by human factors, and improves the surface quality and consistency of the product.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The combined use of the horizontal adjustment device and the rotation adjustment device can precisely adjust the angle and parallelism of the mounting seat, ensure that the polishing belt can apply force evenly in multiple directions, and avoid problems of insufficient or excessive polishing caused by differences in the parallelism of each position of the profile and the height of the weld seam; 2. The clamping and fixing member can achieve stable clamping of the profile. Specifically, the design of the chute and the two clamping blocks on the clamping seat enables the clamping blocks to slide along the chute, so as to adapt to profiles of different widths. The spiral directions of the external threads at both ends of the limit screw rod are opposite. When the limit screw rod rotates, the two clamping blocks will move synchronously in the opposite direction, ensuring uniform distribution of the clamping force and effectively preventing the profile from shifting or loosening during the polishing process.

An adjustment gear is installed on the output shaft of the horizontal adjustment motor 42, and the adjustment gear is meshed with the limit rack 43. This design enables the support plate 41 to move smoothly on the slide rail, thereby realizing precise adjustment in the horizontal direction and ensuring the stability of the profile during the grinding process.

[0036] The horizontal adjustment device 4 can realize precise horizontal position adjustment of the profile during the grinding process. Specifically, the rollers installed on both sides of the lower plate surface of the support plate 41 can roll on the slide rails on the frame 1, ensuring the smooth operation of the entire device. At the same time, the adjustment gear on the output shaft of the horizontal adjustment motor 42 is meshed with the limit rack 43, enabling the horizontal adjustment motor 42 to move the adjustment gear on the limit rack 43, thereby realizing the precise horizontal movement of the support plate 41 and various components installed thereon.
