[0053] Further, the limiting disc 232 is limitingly installed in the supporting groove 221 and plays a supporting and limiting role on the bottom connecting block 231.

[0054] Reference Figures 13-14 One end of the drive rod 24 is rotatably mounted on the bottom end of the drive cylinder 23 and connected to the drive end of the built-in motor. The other end of the drive rod 24 is connected to the polishing head 113. Both ends of the drive rod 24 are provided with extension grooves 19.

[0056] Among them, polishing head 2 112, polishing head 2 112, and polishing head 3 113 are connected to each other and have a certain gap between them to allow for relative movement.

[0057] In this embodiment, the corresponding aluminum sheet to be processed is placed on the grinding conveyor belt 3 set on the upper part of the machine body 1. At the same time, the control panel 5 is controlled to drive the lateral movement mechanism 2 to drive the connected drive chamber 4 to move laterally. During the lateral movement, the sanding belt grinding mechanism 7 and the coarse polishing roller 8 set inside the drive chamber 4 rotate under the drive of the motor. Meanwhile, the lifting frame 12 controls the sanding belt grinding mechanism 7 to move down and contact the surface of the aluminum sheet. At this time, under the continuous conveying action of the grinding conveyor belt 3, the moving direction of the aluminum sheet is opposite to the grinding direction of the sanding belt grinding mechanism 7, thereby canceling out the forces and ensuring the stability of the grinding process.

[0058] Then, when the aluminum sheet travels to the end of the grinding conveyor belt 3, the drive chamber 4 moves through the transverse mechanism 2 and continues to grind the un-grinded surface of the other end of the aluminum sheet.

[0059] In the above-mentioned process of grinding the surface of aluminum sheet, the lifting frame 12 is equipped with a lead screw motor 122. The lead screw motor 122 is driven to rotate under the control of the control panel 5. The rotation of its lead screw body drives the lifting block 121 connected to it to move. The lifting block 121 drives the electric tilting seat 9 on one side to rise and fall, so that the sanding belt grinding mechanism 7 and the coarse polishing roller 8 on one side come into contact with the surface of the aluminum sheet. The coarse polishing roller 8 contacts the surface of the aluminum sheet and performs coarse polishing. Then, during the continuous movement of the aluminum sheet, it is further ground and polished with the sanding belt grinding mechanism 7.

[0060] Wherein, in actual use process, the sand belt polishing mechanism 7 is provided with a protective plate 6, the protective plate 6 effectively protects the debris generated during grinding, and avoids the debris from splashing into the key components.

[0061] Wherein, in actual use process, the grinding conveyor belt 3 is specifically polyurethane material, thereby ensuring high anti-skid performance, avoiding processing quality problems caused by sliding or deviation.

[0062] Wherein, in actual use process, before grinding, according to the size and polishing requirements of the aluminum plate, the corresponding feeding, polishing speed and other parameters of the body 1, the cross slide mechanism 2, the sand belt polishing mechanism 7, the rough polishing roller 8 and the polishing head 11 are adjusted through the control panel 5.

[0063] Further, after single side grinding is completed, the aluminum plate is turned over for reverse side grinding.

[0064] Further, after the grinding operation is completed, the drive cabin 4 is driven to move horizontally by the cross slide mechanism 2, and the lifting frame 12 is driven to move upward by the screw rod motor 122, and at the same time, the electric overturning seat 9 is overturned, so that the sand belt polishing mechanism 7 is overturned to one side, which drives the overturning arm 10 to overturn the horizontal moving arm 14, and the polishing head assembly is perpendicular to the aluminum plate.

[0065] Then, the drive cylinder 23 arranged at the bottom of the horizontal moving arm 14 is driven to rotate by the built-in motor, and drives the drive rod 24 connected thereto to rotate, and drives the polishing head assembly to rotate at high speed to realize inner hole polishing, and then under the driving action of the lifting frame 12 and the cross slide mechanism 2, the polishing head assembly is fed into the hole on the aluminum plate and performs polishing operation.

[0066] Wherein, in the downward movement of the horizontal moving arm 14, the plurality of rubber pressure wheels 161 arranged outside the horizontal moving arm 14 are in contact with the surface of the aluminum plate, and the horizontal moving arm 14 drives the polishing head assembly to continue to move downward, the rubber pressure wheels 161 are further pressed against the aluminum plate by the spring telescopic rod 16, and when the polishing head one 11 in the polishing head assembly is in contact with the hole, the polishing head one 11 is rotated and polished with the inner wall of the hole, and after single hole grinding is completed, the driving block 17 arranged inside the horizontal moving arm 14 drives the horizontal movement, the driving motor 18 arranged inside the driving block 17 drives the driving gear 21 to rotate through the gear set 211, and the driving gear 21 drives the rack 20 arranged inside the horizontal moving arm 14 to complete the horizontal movement function, and in cooperation with the lifting operation of the lifting frame 12 and the horizontal movement operation of the cross slide mechanism 2, the multi-hole grinding and polishing are realized.

[0067] In the actual application process, due to the variety of hole sizes, when the polishing head assembly is in contact with the hole on the surface of the aluminum plate, the polishing head assembly includes, from the outside to the inside, the first polishing head 11, the second polishing head 112 and the third polishing head 113. The first polishing head 11 extends into a hole with the same outer diameter size and completes polishing. When the inner diameter of the corresponding hole is smaller than the polishing outer diameter of the first polishing head 11, the first polishing head 11 cannot extend into the hole, and under the reverse pressure of the aluminum plate surface, the first polishing head 11 moves upward through the internally connected connecting sliding block 29. At this time, the first polishing head 11 is limited to move outside the internal second polishing head 112, and the second polishing head 112 continues to extend into the hole and polishes the hole.

[0068] Similarly, when facing different sizes of holes, the corresponding polishing head assembly larger than the hole size, such as the second polishing head 112 and the first polishing head 11, will be blocked by the small size hole, and through the internally connected spring 28, connecting sliding block 29 and other components, the self-adapting extension effect is realized, and the polishing operation of the third polishing head 113 meeting the size of the corresponding hole is realized.

[0069] In the actual use process, the outer wall of the third polishing head 113 is provided with an extension groove 19, and the extension groove 19 is provided with a spring 28 and a connecting sliding block 29 to meet the free lifting function. This mechanism is also applied to the second polishing head 112 to meet the relative movement operation between the second polishing head 112 and the first polishing head 11.

[0070] Further, due to the different standards of hole sizes, such as strip-shaped and arc-shaped holes, the driving block 17 is limited to move in the sliding groove 141 at the bottom of the transverse arm 14 through the engagement of the gear groove, drives the polishing head assembly to move transversely, and then drives the polishing head assembly to be limited to move in the corresponding strip-shaped hole and complete the grinding operation.

[0071] Among them, when the arc-shaped hole grinding operation is performed, the polishing head assembly is deviated in horizontal position under the guidance of the arc-shaped hole. At this time, the driving cylinder 23 connected with the polishing head assembly is limited to move in the connecting disc 22. The connecting disc 22 is provided with a plurality of folding connecting rods 25. The folding connecting rods 25 are connected with the connecting block 231 installed on the upper part of the driving cylinder 23. When the polishing head assembly deviates, the deviation is directly reflected on the connecting block 231. When the connecting block 231 moves to one side, it drives a plurality of folding connecting rods 25 to fold and unfold. At the same time, the limiting disc 232 connected with the connecting block 231 is limited to move in the supporting groove 221 arranged inside the connecting disc 22 to meet the basic supporting and limiting effect.

[0072] Under the synchronous adjustment of the plurality of folding connecting rods 25, the polishing head assembly can realize a certain virtual movement through the folding connecting rods 25 under the deviation of the arc-shaped hole, and effectively adapt to the size of the arc-shaped hole.

[0073] Meanwhile, the folding connecting rod 25 comprises a pair of connecting rod members connected to each other and forming a "V" shape, and is connected by a spring 26 therebetween, thereby satisfying self-adaptive reset and compression.

[0074] In actual use, the rubber pressing wheel 161 can move laterally to a certain extent under the lateral movement of the driving cabin 4, so that the polishing head assembly can move laterally in the hole while affecting the grinding of the aluminum plate.

[0075] It is worth noting that the spring telescopic rod 16 comprises an inner and outer sleeve connected to each other, and cooperates with internal springs and other components to realize the functions of expansion and bearing. The specific components and principles not described in detail are well-known technical knowledge to those skilled in the art, and therefore will not be described in detail.

[0076] In actual use, the connecting sliding block 29 provided on the inner wall of the polishing head three 113 connects the inner wall of the polishing head two 112, and the spring two 28 is pressed during the movement of the polishing head two 112.

[0077] It is worth noting that the bottom end surfaces of the polishing head three 113, the polishing head two 112 and the polishing head one 11 are not provided with grinding materials, thereby avoiding secondary grinding of the surface of the aluminum plate.

[0078] It is worth noting that the lateral movement mechanism 2 is provided with corresponding servo motors, lead screws and other transmission components, which realize the lateral movement function of the driving cabin 4 in cooperation with the control panel 5.

[0079] It is worth noting that the electrically driven turnover seat 9 is provided with a motor inside and realizes the turnover function by rotating the motor, which will not be described in detail.

[0080] It is worth noting that the sizes of the polishing head one 11, the polishing head two 112 and the polishing head three 113 are determined according to the standard size of the workpiece hole specified by the on-site workshop.

[0081] It is worth noting that the lead screw motor 122, also known as a screw motor, is a motor that converts rotary motion into linear motion through a lead screw and a nut. It mainly includes a power source, i.e. a motor, which cooperates with a lead screw to realize the lifting driving function through the connection of the lifting block 121. The specific driving principle and structure not described in detail are well-known technical knowledge to those skilled in the art, and therefore will not be described in detail.

[0082] Among them, it is worth noting that the sand belt polishing mechanism 7 specifically includes a sand belt and a driving mechanism, the driving mechanism drives the sand belt to rotate to realize the function of rotary grinding, and the driving mechanism synchronously drives the rough polishing roller 8 near one side through the chain wheel assembly, the driving principle and transmission connection mode involved are prior art, the specific driving principle and structure not described above are technical common sense set by those skilled in the art, so no more description is made.

[0083] In the application, through the components such as the lifting frame 12, the electric overturning seat 9 and the transverse arm 14 arranged in the driving cabin 4, the sand belt polishing mechanism 7 and the polishing head assembly, the rapid switching and operation function of the plane grinding and hole grinding modes are realized, and in the hole grinding process, through the folding connecting rod 25, the connecting block 231 and the polishing head assembly matched with each other, the self-adaptive offset function of the polishing head is realized, the adaptive adjustment operation can be quickly made for different sizes of holes, the grinding efficiency and machining precision are effectively improved, and the time and manpower required for replacing the grinding equipment are saved.

[0084] The above is only the preferred specific embodiment of the application, but the protection scope of the application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
