Description

Technical Field

[0001] The present invention relates to the technical field of aluminum sheet processing, and particularly relates to a composite machine tool for aluminum sheet processing. Background Art

[0002] An aluminum plate refers to a rectangular material with a uniform thickness and a rectangular cross-section made of pure aluminum or aluminum alloy materials through pressure processing. Internationally, aluminum materials with a thickness above 0.2 mm, below 500 mm, a width above 200 mm, and a length within 16 m are customarily referred to as aluminum sheets or aluminum plates.

[0003] Currently, during the processing of aluminum plate parts, it is often necessary to polish them. The traditional aluminum polishing method is mostly achieved by manual cooperation with a grinding machine. Although it can meet the basic grinding requirements, in actual use, the traditional grinding device can only handle small batches of operations and can only polish the surface of the plate. However, holes or hole burrs of different sizes on the plate still require secondary processing, which is a relatively cumbersome process and the processing accuracy and efficiency will be reduced. Moreover, as the operation time increases, the efficiency will become even lower. Therefore, there is an urgent need for a composite machine tool for aluminum sheet processing.

[0041] Among them, the sanding belt grinding mechanism 7 includes a sanding belt and a driving mechanism. The driving mechanism is installed and driven through the driving arm 15, and realizes the rotation and grinding of the sanding belt in the sanding belt grinding mechanism 7. At the same time, the sanding belt driving mechanism drives the rough polishing roller 8 on the adjacent side through a sprocket transmission part, thereby realizing the basic planar grinding function.

[0044] Reference Figures 3-4 As shown in Figures 3-4 , under the flipping drive of the electric flipping seat 9, the sanding belt grinding mechanism 7 and the driving arm 15 can be switched between the planar grinding mode and the hole grinding mode. During the switching process between the two, the flipping operation is realized through the electric flipping seat 9, and the corresponding grinding parts are made flush with the aluminum plate parts.

[0045] Reference Figures 7-9 As shown in Figures 7-9 , a plurality of spring telescopic rods 16 are symmetrically installed on one side of the transverse moving arm 14 through a fixed seat. One end of the spring telescopic rod 16 is fixedly installed on one side of the transverse moving arm 14, and the other end of the telescopic end is rotatably installed with a rubber pressing wheel 161. The rubber pressing wheel 161 is installed to roll in a limited manner on the surface of the aluminum plate part.

[0046] Among them, a sliding groove 141 is formed on one side of the transverse moving arm 14. A rack 20 is installed on one side of the inner wall of the sliding groove 141. One side of the rack 20 is connected to a driving block 17 through gear meshing. The driving block 17 is installed in the sliding groove 141 in a limited sliding manner, and a connecting disk 22 is installed at the bottom of the driving block 17. The bottom of the connecting disk 22 is connected to a driving cylinder 23. A driving rod 24 is fixedly installed in the middle of the bottom end of the driving cylinder 23. A third polishing head 113, a second polishing head 112, and a first polishing head 11 are sequentially sleeved on the driving rod 24 from the inside out.

[0047] Referring to Figures 9-14 , a driving motor 18 is installed in the middle of the driving block 17. The output end of the driving motor 18 is drivingly connected to a gear set 211. The gear set 211 is installed inside the driving block 17. One side adjacent to the gear set 211 is connected to a driving gear 21 through gear meshing. One side of the driving gear 21 extends out of the outer wall of the driving block 17 and meshes with the tooth grooves of the rack 20.

[0048] Among them, a notch is formed on one side of the outer wall of the driving block 17. A driving gear 21 is rotatably installed in the notch. The driving gear 21 rotates through the transmission of the gear set 211, and the other side of the driving gear 21 rotates in transmission with the rack 20.

[0049] Among them, a connecting disk 22 is installed at the bottom end of the driving block 17. A cylindrical notch is formed inside the connecting disk 22. One side of the top of the cylindrical notch is divided into a supporting groove 221 by a partition. A limiting disk 232 is installed in the supporting groove 221 in a limited movable manner. The bottom end of the limiting disk 232 extends out of the bottom end of the supporting groove 221 and is connected to a connecting block 231. The bottom of the connecting block 231 is fixedly installed with a driving cylinder 23. A motor is built into the driving cylinder 23 to drive the driving rod 24.

[0050] Among them, a plurality of rotating seats 27 are installed on the inner wall of the bottom of the connecting disk 22. One end of each rotating seat 27 is rotatably installed with a folding connecting rod 25. The folding connecting rod 25 is in a "V" shape, and the folding connecting rods 25 rotate towards each other through a pin shaft. The other ends of the folding connecting rods 25 are connected to the outer wall of the connecting block 231 installed in the middle of the connecting disk 22.

[0051] Among them, a first spring 26 is fixedly installed in the middle of the folding connecting rod 25. The two ends of the first spring 26 are respectively connected to the two ends of the folding connecting rod 25. When the folding connecting rod 25 rotates, the first spring 26 is adaptively compressed by the rotation of the connecting rod.

[0052] Among them, a through hole is formed in the middle of the supporting groove 221 for the movement of the connecting block 231.

[0053] Further, the limiting disk 232 is installed in the supporting groove 221 in a limited manner and plays a role in supporting and limiting the bottom connecting block 231.

[0054] Reference Figures 13-14 Figures 13-14 , one end of the driving rod 24 is rotatably installed at the bottom end of the driving cylinder 23 and is connected to the driving end of the built-in motor, and the other end of the driving rod 24 is connected with a third polishing head 113. Extension grooves 19 are provided at both outer ends of the driving rod 24. A second spring 28 is fixedly installed at the top end inside the extension groove 19. The other end of the second spring 28 is connected with a connecting slider 29. Both ends of the connecting slider 29 are installed in the extension groove 19 in a limited sliding manner, and the outer side of the connecting slider 29 is connected with the second polishing head 112.

[0055] Among them, a third polishing head 113 is provided at the bottom of the driving rod 24, and a second polishing head 112 is sleeved outside the driving rod 24. The second polishing head 112 is installed on the outside of the driving rod 24 in a limited sliding manner. An extension groove 19 corresponding to the driving rod 24 and its internal spring and slider assembly are provided on the outside of the second polishing head 112, and it is connected with the first polishing head 11.

[0056] Among them, the second polishing head 112, the second polishing head 112, and the third polishing head 113 are sleeved and connected to each other, and a certain gap is left between them to meet the relative movement.

[0057] In this embodiment, the corresponding aluminum sheet to be processed is placed on the grinding conveyor belt 3 provided on the upper part of the machine body 1. At the same time, by controlling the control panel 5, the transverse movement mechanism 2 drives the driving cabin 4 connected thereto to move horizontally. During the horizontal movement, the abrasive belt grinding mechanism 7 and the rough polishing roller 8 provided inside the driving cabin 4 rotate under the drive of the motor. At the same time, the lifting frame 12 controls the abrasive belt grinding mechanism 7 to move downward 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 abrasive belt grinding mechanism 7, so that the acting forces are offset and the stability during the grinding process is ensured.

[0058] Then, when the aluminum sheet reaches the end of the grinding conveyor belt 3, the driving cabin 4 moves through the transverse movement mechanism 2, and the unground surface of the other end of the aluminum sheet is continuously ground.

[0059] During the above-mentioned flat grinding process of the aluminum sheet, among them, a lead screw motor 122 is provided inside the lifting frame 12. The lead screw motor 122 is driven to rotate under the control of the control panel 5. Through the rotation of its lead screw rod body, the lifting block 121 connected thereto is driven to move. The lifting block 121 drives the electric flipping seat 9 on one side to move up and down, and makes the abrasive belt grinding mechanism 7 and the rough polishing roller 8 on one side contact the surface of the aluminum sheet. Among them, the rough polishing roller 8 contacts the surface of the aluminum sheet and performs rough polishing. Then, during the continuous movement of the aluminum sheet, it is further ground and polished by the abrasive belt grinding mechanism 7.

[0060] Among them, during actual use, a protective plate 6 is arranged above the abrasive belt grinding mechanism 7. The protective plate 6 effectively protects the debris generated during grinding processing to prevent the debris from splashing into key components.

[0061] Among them, during actual use, the grinding conveyor belt 3 is specifically made of polyurethane material, thereby ensuring high anti-slip performance and avoiding processing quality problems caused by sliding or deviation.

[0062] Among them, during actual use, before grinding processing, according to the size and grinding requirements of the aluminum plate, parameters such as the corresponding feeding and grinding speed of the transverse movement mechanism 2, abrasive belt grinding mechanism 7, rough polishing roller 8, and polishing head one 11 in the machine body 1 are adjusted through the control panel 5.

[0063] Furthermore, after one-sided grinding is completed, the aluminum plate is turned over for reverse grinding.

[0064] Furthermore, after the grinding operation is completed, the drive cabin 4 moves horizontally under the drive of the transverse movement mechanism 2. At the same time, the lifting frame 12 drives the lifting block 121 to move upward through the screw motor 122. Synchronously, the electric flipping seat 9 performs a flipping operation, causing the abrasive belt grinding mechanism 7 to flip to one side. This drives the flipping arm 10, causing the transverse movement arm 14 to flip and making the polishing head assembly perpendicular to the aluminum plate part.

[0065] Subsequently, a drive cylinder 23 arranged at the bottom of the transverse movement arm 14 has a built-in motor that drives the connected drive rod 24 to rotate, driving the polishing head assembly to rotate at high speed to achieve inner hole grinding. Then, under the drive of the lifting frame 12 and the transverse movement mechanism 2, the polishing head assembly feeds into the holes opened on the aluminum plate for polishing operations.

[0066] Among them, during the downward movement of the transverse movement arm 14, multiple rubber pressing wheels 161 arranged on the outer side of the transverse movement arm 14 come into contact with the surface of the aluminum plate. At the same time, the transverse movement arm 14 drives the polishing head assembly to continue moving downward. The rubber pressing wheels 161 further press the aluminum plate through the spring telescopic rod 16. And when the polishing head one 11 in the polishing head assembly comes into contact with the hole in an extended manner, the polishing head one 11 rotates and grinds the inner wall of the hole. At the same time, after single-hole grinding is completed, a drive block 17 arranged inside the transverse movement arm 14 drives the transverse movement. The drive motor 18 arranged inside it drives the drive gear 21 to rotate through the gear set 211. The drive gear 21 is meshed with the rack 20 inside the transverse movement arm 14 to complete the transverse movement function. At the same time, in cooperation with the lifting operation of the lifting frame 12 and the transverse movement operation of the transverse movement mechanism 2, multi-hole grinding and polishing are achieved.

[0067] Among them, in the actual application process, due to the diverse opening sizes, when the polishing head assembly contacts the holes on the surface of the aluminum sheet, the polishing head assembly includes a first polishing head 11, a second polishing head 112, and a third polishing head 113 from outside to inside. The first polishing head 11 extends into the hole with the same outer diameter size as it and completes the grinding. And when the inner diameter of the corresponding hole is smaller than the grinding outer diameter of the first polishing head 11, the first polishing head 11 cannot extend into the hole. Under the reverse pressing action on the surface of the aluminum sheet, the first polishing head 11 moves upward through the connecting slider 29 connected inside. At this time, the first polishing head 11 is limited to move outside the inner polishing head 112, and the second polishing head 112 continues to extend into the hole and grinds the hole.

[0068] Similarly, when facing holes of different sizes, the corresponding polishing head assemblies larger than the hole size, such as the second polishing head 112 and the first polishing head 11, will be blocked by the small-sized holes, and the adaptive telescopic effect is realized through components such as the second spring 28 and the connecting slider 29 connected inside, so as to realize the grinding operation of the third polishing head 113 that meets the corresponding hole size.

[0069] Among them, in the actual use process, an extension groove 19 is provided on the outer wall of the third polishing head 113, and a second spring 28 and a connecting slider 29 are arranged in the extension groove 19 to meet the free lifting function. Among them, 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] Furthermore, due to the different opening size standards, such as strip-shaped and arc-shaped holes, the driving block 17 is limited to move in the sliding groove 141 opened at the bottom of the cross-moving arm 14 through the tooth groove engagement, and drives the polishing head assembly to perform cross movement, 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, during the grinding operation of the arc-shaped hole, the polishing head assembly is offset horizontally under the guiding action of the arc-shaped hole. At this time, the driving cylinder 23 connected to the polishing head assembly is limited to move in the connecting disk 22. A plurality of folding link rods 25 are arranged in the connecting disk 22. The folding link rods 25 are connected to the connecting block 231 installed on the upper part of the driving cylinder 23. When the polishing head assembly is offset, the offset amount is directly reflected on the connecting block 231. When the connecting block 231 moves to one side, it drives a plurality of folding link rods 25 to fold and unfold. At the same time, the limiting disk 232 connected to the connecting block 231 is limited to move in the supporting groove 221 arranged inside the connecting disk 22 to meet the basic supporting and limiting effects.

[0072] Among them, under the synchronous adjustment action of the plurality of folding link rods 25, when the polishing head assembly is offset by the arc-shaped hole, a certain virtual displacement can be realized through the folding link rods 25, so as to effectively adapt to the size of the arc-shaped hole.

[0073] Meanwhile, the folding link 25 includes a pair of link members that are connected to each other and form a "V" shape, and are connected by a first spring 26 therebetween, so as to achieve adaptive resetting and compression.

[0074] Among them, during actual use, the rubber pressing wheel 161 can perform a certain degree of lateral movement under the lateral movement of the drive cabin 4, and the polishing head assembly can perform lateral movement inside the hole while affecting the grinding of the aluminum plate.

[0075] It should be noted that the spring telescopic rod 16 includes an inner cylinder and an outer cylinder that are sleeved and connected, and cooperates with internal spring and other components to achieve the functions of telescoping and bearing. The specific components and principles not described in detail above are common technical knowledge known to those skilled in the art, so no further elaboration will be made.

[0076] Among them, during actual use, the connecting slider 29 provided on the inner wall of the third polishing head 113 is connected to the inner wall of the second polishing head 112. During the movement of the second polishing head 112, the second spring 28 will be pressed.

[0077] It should be noted that the bottom end surfaces of the third polishing head 113, the second polishing head 112, and the first polishing head 11 are not provided with grinding materials, so as to avoid secondary grinding of the surface of the aluminum plate.

[0078] It should be noted that the lateral movement mechanism 2 is provided with corresponding transmission components such as a servo motor and a lead screw, and cooperates with the control panel 5 to achieve the basic lateral movement function of the drive cabin 4.

[0079] It should be noted that the electric flipping seat 9 is provided with a motor inside and realizes the flipping function through the rotation of the motor. No further explanation will be given here.

[0080] It should be noted that the sizes of the first polishing head 11, the second polishing head 112, and the third polishing head 113 are determined according to the standard size of the workpiece opening specified by the on-site workshop.

[0081] It should be noted that the lead screw motor 122, also known as the screw motor, is a motor that converts rotational motion into linear motion through the rotation of a lead screw and a nut. It mainly includes a power source, that is, a motor, which cooperates with the lead screw and realizes the lifting drive function through the connection of the lifting block 121. The specific drive principles and structures not described in detail above are common technical knowledge set by those skilled in the art, so no further elaboration will be made.

[0082] Among them, it is worth noting that the abrasive belt grinding mechanism 7 specifically includes an abrasive belt and a driving mechanism. The driving mechanism drives the abrasive belt to rotate to achieve the rotary grinding function. At the same time, the driving mechanism synchronously drives the rough polishing roller 8 on the adjacent side through a sprocket assembly. The driving principle and transmission connection method involved are both prior arts. The specific driving principles and structures not described in detail above are all technical common sense set by those skilled in the art, so no further elaboration will be made.

[0083] In the present invention, through components such as the lifting frame 12, electric tilting seat 9, and transverse moving arm 14 provided inside the driving cabin 4, in cooperation with the abrasive belt grinding mechanism 7 and the polishing head assembly, the rapid switching and operation functions of the plane grinding and hole grinding modes are realized. At the same time, during the hole grinding process, through components such as the folding connecting rod 25 and the connecting block 231 and in cooperation with the mutually sleeved polishing head assembly, the adaptive offset function of the polishing head can be realized, and the adaptive adjustment operation can be quickly performed for holes of different sizes, effectively improving the grinding efficiency and machining accuracy, and saving the time and labor required for replacing the grinding equipment.

[0084] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
