[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 As shown, the present invention is a grinding and polishing device for automotive aluminum profiles. Example 1

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this invention, a technical solution is provided: a fixed mounting frame 1, with conveying rollers 108 at both the left and right ends of the inner side of the fixed mounting frame 1 for stable conveying of automotive aluminum profiles; a roller 305 at the upper left end of the fixed mounting frame 1 for detecting the surface flatness of the automotive aluminum profiles; a first grinding wheel 4058 at the upper middle part of the fixed mounting frame 1 for grinding and polishing the automotive aluminum profiles; and movable clamping rods 206 connected to the outer frame 2 at both the front and rear sides of the upper middle part of the fixed mounting frame 1. Furthermore, a linkage gear disk 105 is fixedly installed at both the front and rear ends of the conveyor roller 108. An internal toothed belt 107 is provided on the outer side of the linkage gear disk 105 for meshing connection. Side baffles 106 that can center and limit the internal toothed belt 107 are also provided on the front and rear sides of the linkage gear disk 105. The conveyor rollers 108 are equidistantly distributed on the left and right sides inside the fixed mounting frame 1. The fixed mounting frame 1 has drainage holes 103 on its inner side for draining impurities and sewage.

[0023] Furthermore, water tanks 202 are fixedly installed at both the front and rear ends of the inner side of the outer frame 2. An inclined water spray pipe 2021 is installed at the lower end of the water tank 202 for spraying water during grinding and polishing.

[0024] Furthermore, a hydraulic telescopic rod 203 is installed on the lower side of the outer end of the outer frame 2, and a clamping frame 204 located inside the outer frame 2 is provided at the inner end of the hydraulic telescopic rod 203. A first damping spring 205 connected to the movable clamping rod 206 is provided on the inner side of the clamping frame 204. The movable clamping rod 206 forms an elastic telescopic movement within the clamping frame 204 via the first damping spring 205. The movable clamping rod 206 is equidistantly distributed and independently set at the inner end of the clamping frame 204.

[0025] Specifically, after placing the fixed mounting frame 1 in the designated position, the sewage tank 101 is threadedly connected to the lower inner end of the fixed mounting frame 1 using the first bolt 102. At this time, the automotive aluminum profile is placed on the upper surface of the conveyor roller 108. Both the front and rear ends of the conveyor roller 108 are fixedly mounted with linkage gear disks 105, and the outer side of the linkage gear disks 105 is meshed with an internal toothed belt 107. When the first servo motor 104 is turned on to rotate the linkage gear disks 105, the linkage gears 105 are driven by the internal toothed belt 107. The wheel 105 and its corresponding unit rotate synchronously and in the same direction, thereby driving the conveying shaft roller 108 to rotate through the linkage gear disk 105. This allows for stable left or right conveying of the automotive aluminum profile. When the automotive aluminum profile is conveyed to the upper middle part of the fixed mounting frame 1, the conveying state of the conveying shaft roller 108 can be stopped. The hydraulic telescopic rod 203 is opened to drive the clamping frame 204 to move inward as a whole. The movable clamping rod 206 is used to position and clamp the automotive aluminum profile so that the first grinding wheel 4058 can perform grinding and polishing operations. Side baffles 106 are fixedly installed at both the front and rear ends of the linkage gear disk 105, which can center the internal tooth belt 107 that meshes with the linkage gear disk 105, and prevent the internal tooth belt 107 from disengaging from the linkage gear disk 105 during linkage rotation. The movable clamping rod 206 forms an elastic telescopic movement within the clamping frame 204 via the first damping spring 205. The movable clamping rod 206 is equidistantly distributed and independently set at the inner end of the clamping frame 204, which can position and clamp specially shaped automotive aluminum profiles. When the hydraulic telescopic rod 203 is opened, the clamping frame 204 moves inward as a whole, and the front and rear ends of the automotive aluminum profile are adaptively adjusted and clamped through the elastic telescopic movement of the movable clamping rod 206, so as to improve the clamping and limiting effect of the automotive aluminum profile. The outer frame 2 is connected to the fixed mounting frame 1 by means of a thread through the second bolt 201, which enables the outer frame 2 to be securely connected and installed with the fixed mounting frame 1, and facilitates the disassembly and replacement of the outer frame 2 as a whole in the future. Additionally, water tanks 202 are fixedly installed on both the front and rear sides of the inner end of the outer frame 2, and a tilted water spray pipe 2021 is fixedly installed at the lower end of the water tank 202. When the first grinding wheel 4058 is used to grind and polish the automotive aluminum profile, the water spray pipe 2021 can be used to spray out the clean water in the water tank 202 to prevent sparks or dust debris from being generated during the grinding and polishing process, and to avoid splashing and polluting the surrounding air environment, thereby achieving the effect of dust reduction. A drain hole 103 is provided on the inner side of the fixedly installed frame 1, so that the generated debris and dust can flow into the sewage tank 101 along with the sewage for unified collection and subsequent centralized treatment. Example 2

[0026] Please see Figure 1 , Figure 2 and Figure 5 In this invention, a technical solution is provided: the upper end of the roller 305 is provided with a movable support frame 304 connected to the auxiliary cavity frame 302, and the rear end of the movable support frame 304 is provided with a scribing pen 3041 for scribing the flatness line diagram of the automotive aluminum profile on the drawing paper 308. Furthermore, the roller 305 forms a rotating structure at the lower end of the movable support frame 304 through the built-in bearing, and the movable support frame 304 forms an elastic telescopic movement in the auxiliary cavity frame 302 through the second damping spring 303. The outer end of the auxiliary cavity frame 302 is provided with a fixed mounting plate frame 301 that is fixedly connected to the first cylinder 3.

[0027] Furthermore, a take-up roller 307 is provided on the inner side of both the left and right ends of the fixed mounting plate 301. The outer side of the take-up roller 307 is wrapped with drawing paper 308 and is pressed against the engraving pen 3041.

[0028] Specifically, in embodiment one, a first cylinder 3 is installed on the lower left side of the outer frame 2, and a fixed mounting plate 301 is fixedly connected to the lower end of the first cylinder 3. During the process of conveying the automotive aluminum profile to the right, the first cylinder 3 is opened to drive the fixed mounting plate 301 to move downward as a whole, and the lower surface of the roller 305 contacts the upper surface of the automotive aluminum profile. When the automotive aluminum profile moves to the right, the roller 305 can roll on the upper surface of the automotive aluminum profile. Since the roller 305 is connected to the movable support frame 30 by an internal bearing, The lower end of 4 forms a rotating structure, and the movable support frame 304 forms an elastic telescopic movement in the auxiliary cavity frame 302 through the second damping spring 303. At this time, if the upper surface of the automotive aluminum profile is not flat enough, the roller 305 will move up and down, and the movable support frame 304 will move up and down reciprocally in the auxiliary cavity frame 302. At the same time, the engraving pen 3041 fixedly installed at the rear end of the movable support frame 304 can be used to engrave a route map on the drawing paper 308 for later viewing, so as to detect the flatness of the automotive aluminum profile. The fixed mounting plate 301 has a winding roller 307 movably connected to both the left and right sides inside, and the winding roller 307 is wrapped around the drawing paper 308. When the second servo motor 306 is turned to rotate the winding roller 307, the drawing paper 308 can be moved to the left to be wound up, thereby collecting the engraving of the engraving pen 3041. The surface flatness of the automotive aluminum profile can be continuously collected and detected without the first cylinder 3 moving, which is convenient for subsequent flatness correction operations. The flatness detection data can be transmitted to the control module by the staff, and then the lifting force of the second cylinder 404 can be operated by the control module. Example 3

[0029] Please see Figure 2 , Figure 6 , Figure 7 and Figure 8 In this invention, a technical solution is provided: a reciprocating screw 401 is provided on the inner side of the right end of the outer frame 2, which can reciprocate the movable support top frame 4 back and forth; a grinding support horizontal plate 405 is provided below the movable support top frame 4, which can be raised and lowered by a second cylinder 404; and a driven gear disk 4053 is provided on the lower left end of the grinding support horizontal plate 405, which can adjust the first grinding wheel 4058 by equal distance rotation. Furthermore, the movable support top frame 4 is connected to the reciprocating screw 401 by a thread. The movable support top frame 4 forms a locking sliding structure in the outer frame 2 through the fixed limiting rod 403, which is used to make the movable support top frame 4 move back and forth as a whole.

[0030] Furthermore, an auxiliary support frame 406 is fixedly installed on the lower right side of the grinding support plate 405. A worm gear 408 is provided on the inner side of the right end of the auxiliary support frame 406. A worm wheel 409 is connected to the left side of the worm gear 408. A drive gear disk 4010 connected to the auxiliary support frame 406 is fixedly installed at the lower end of the worm wheel 409. The worm 408 and the worm wheel 409 are meshed together.

[0031] Furthermore, the worm 408 and the worm wheel 409 are rotatably connected on the auxiliary support frame 406. The worm wheel 409 is connected to the driven gear disk 4053 by meshing. The inner side of the driven gear disk 4053 is provided with a through arc-shaped groove 4054 that can accommodate the up and down movement of the movable support plate 4055. A central support positioning column 4051 is installed on the lower left side of the grinding support plate 405, and an irregular groove 4052 is opened on the inner side of the central support positioning column 4051 to make the movable support plate 4055 move in a ring.

[0032] Furthermore, the movable support plate 4055 forms a locking lifting motion on the driven gear disk 4053 through the through arc groove 4054, and the movable support plate 4055 makes a circular motion around the central support positioning column 4051 through the irregular groove 4052. The lower end of the movable support plate 4055 is provided with a detachable grinding mounting bracket 4056 connected to the first grinding wheel 4058. The first grinding wheel 4058 also includes a second grinding wheel 40581 and a third grinding wheel 40582, which are used to perform grinding and polishing operations on automotive aluminum profiles to different degrees.

[0033] Specifically, in conjunction with Embodiments 1 and 2, after the automotive aluminum profile reaches the upper middle part of the fixed mounting frame 1 and is positioned and clamped by the movable clamping rod 206, the first grinding wheel 4058 can be used to grind and polish the automotive aluminum profile. When the second cylinder 404 is opened to lower the grinding support plate 405, the first grinding wheel 4058, located on the inner side of the lower end of the grinding mounting frame 4056, can contact the upper surface of the automotive aluminum profile. At this time, the fourth servo motor 4057 can be turned to rotate the first grinding wheel 4058 to grind and polish the automotive aluminum profile. This is achieved by using a screw thread between the movable support top frame 4 and the reciprocating screw 401. The three servo motors are connected in a pattern. When the third servo motor 402 is turned on to rotate the reciprocating screw 401, the movable support top frame 4 can move back and forth on the fixed limit rod 403 to facilitate operation on different width surfaces of the automotive aluminum profile, so as to achieve a complete operation effect. In addition, the second cylinder 404 is connected to the control module. The control module can analyze the surface flatness of the automotive aluminum profile based on the engraving data of the first cylinder 3. When the first grinding wheel 4058 is used for operation, the lifting and lowering pressure of the second cylinder 404 can be controlled to apply pressure and grind the concave corners of the automotive aluminum profile to promote the grinding effect. The worm gear 409 is fixedly connected to the drive gear disk 4010. When the fifth servo motor 407 installed at the front end of the auxiliary support frame 406 is opened and the worm 408 is rotated, the worm gear 409 meshing with the worm 408 can be driven to rotate synchronously. This causes the worm gear 409 to drive the drive gear disk 4010 to rotate as a whole, and causes the driven gear disk 4053 meshing with the drive gear disk 4010 to rotate under the central bearing positioning column 4051. This allows the first grinding wheel 4058 to be replaced as needed, thereby achieving different degrees of grinding and polishing operations. This avoids the problem of manually changing grinding tools, which is time-consuming, labor-intensive, and reduces work efficiency. The movable support plate 4055 engages with the driven gear disk 4053 via a through arc-shaped groove 4054, creating a locking lifting motion. A round rod at the inner end of the movable support plate 4055 rotates in a ring around the central support positioning column 4051 via a shaped groove 4052. Since the right end of the shaped groove 4052 is horizontal and its left end forms a downward "V" shape, the movable support plate 4055 rotates in a ring around the central support positioning column 4051 during the rotation of the driven gear disk 4053. When the movable support plate 4055 reaches the central support positioning column... When the right end of the column 4051 is reached, the movable support plate 4055 will move upward as a whole. When the movable support plate 4055 reaches the left end of the central bearing positioning column 4051, the movable support plate 4055 will move downward as a whole. This will create a height difference distribution of the movable support plate 4055, which is divided into three equal parts with respect to the central bearing positioning column 4051. The movable support plate 4055 moves up and down in the inner side of the driven gear disk 4053. Before use, lubricating oil needs to be applied to the connection between the movable support plate 4055 and the central bearing positioning column 4051 to avoid blockage during the adjustment process. Furthermore, the diameter of the driven gear disk 4053 is three times that of the driving gear disk 4010. When the driving gear disk 4010 rotates one revolution, it can drive the driven gear disk 4053 to rotate one-third revolution, thereby achieving the function of three equal division and equidistant adjustment, so that the first grinding wheel 4058 can be automatically replaced according to different needs. The first grinding wheel 4058 also includes a second grinding wheel 40581 and a third grinding wheel 40582. The first grinding wheel 4058 is used for rough grinding of the automotive aluminum profile to smooth out larger materials such as burrs on the surface. It generally uses an 80-120 grit grinding wheel or belt. Then, the second grinding wheel 40581 is used to perform fine grinding of the automotive aluminum profile to eliminate coarse scratches from the grinding stage and prepare for polishing. It generally uses a 320-800 grit. Finally, the third grinding wheel 40582 is used to polish the automotive aluminum profile to make its surface smoother and brighter. It generally uses a grit greater than 1000 grit.
