Description

Technical Field

[0001] This application relates to the technical field of grinding equipment, and in particular to a grinding device for aluminum frames of curtain walls. Background Technology

[0002] Aluminum curtain walls are curtain walls made of aluminum alloy. They are lightweight, high-strength, and corrosion-resistant, and are commonly used for the exterior decoration of modern buildings. Aluminum curtain walls are composed of aluminum panels, aluminum alloy profiles, glass, and other materials, and can achieve different architectural effects through various structural forms.

[0003] Reference Figure 1 Aluminum sheets are one of the main materials for making aluminum curtain walls. When manufacturing aluminum alloy curtain walls, the aluminum sheets need to be cut and bent to form the aluminum frame 9. Because of material deformation and uneven stress distribution after bending, stress concentration may occur at the bend of the aluminum frame 9. Welding solder to the inner wall of the bend can increase the strength of the bend and reduce stress concentration to some extent. To ensure the flatness of the aluminum frame 9 surface, the weld 91 on the inner wall of the bend is ground to make the weld 91 surface as smooth as possible, and the transition between the weld 91 and the inner wall surface of the aluminum frame 9 is smooth.

[0004] In the related technology, when the grinding machine grinds the weld seam 91 on the aluminum frame 9, the aluminum frame 9 is clamped and positioned so that the grinding disc grinds along each weld seam 91 in sequence, resulting in low grinding efficiency. Summary of the Invention

[0005] To improve the grinding efficiency of aluminum frames for curtain walls, this application provides a grinding device for aluminum frames for curtain walls.

[0006] This application provides a grinding device for aluminum frames of curtain walls, which adopts the following technical solution:

[0007] A curtain wall aluminum frame grinding device, comprising,

[0008] Processing table;

[0009] A lifting support, comprising a support base slidably disposed on a processing table, a lifting plate slidably connected to the support base, and two mounting plates rotatably disposed on both sides of the lifting plate;

[0010] A first driving component is disposed on the lifting plate and is used to drive the mounting plate to rotate.

[0011] A grinding assembly, comprising a grinding component and a first driving source for driving the grinding component to rotate, wherein the grinding component is provided in a one-to-one correspondence with the mounting plate, and the grinding component is rotatably disposed at one end of the mounting plate;

[0012] A positioning mechanism is provided on the processing table and is used to position the aluminum frame.

[0013] By adopting the above technical solution, the positioning mechanism positions the aluminum frame to be ground on the processing table. Grinding components are rotatably mounted on the mounting plates at both ends of the lifting support. The first driving component drives the mounting plates to move away from the lifting support, so that the two grinding components are positioned opposite the weld seams at both ends of the mounting frame. The sliding lifting plate brings the grinding components into contact with the weld seams, activating the first driving source to rotate the grinding components and grind the weld seams. As the grinding components rotate, the support base slides on the processing table, causing the grinding components to move along the length of the weld seams, allowing for comprehensive grinding of the weld seams. The two grinding components can simultaneously grind the two opposite weld seams on the aluminum frame, effectively improving grinding efficiency.

[0014] When the mounting plate rotates, the horizontal distance between the grinding parts and the lifting support can be adjusted to expand the grinding range of the grinding assembly.

[0015] Optionally, the machining table is provided with a sliding groove for the support base to slide, and a drive screw is rotatably installed in the sliding groove. The drive screw passes through the support base and is threadedly connected to the support base. The machining table is provided with a second drive source for driving the drive screw to rotate.

[0016] By adopting the above technical solution, when the second drive source drives the drive screw to rotate, the support base can slide along the working groove, so that the grinding part located on the mounting plate can move along the weld length direction under the drive of the support base.

[0017] Optionally, the support base is provided with a drive assembly for driving the lifting plate to slide, the drive assembly including a height adjustment screw and a third drive source;

[0018] One end of the height adjustment screw is rotatably connected to the support base, and the other end passes through the lifting plate and is threadedly connected to the lifting plate.

[0019] A guide rod is also provided on one side of the height adjustment screw, and a receiving groove is provided on the lifting plate for the guide rod to slide.

[0020] By adopting the above technical solution, the third drive source drives the height adjustment screw to rotate. The lifting plate, which is threadedly connected to the height adjustment screw, moves vertically with the rotation of the screw, thereby realizing the lifting of the lifting plate. This allows the mounting plate to move vertically with the lifting plate so that the grinding part can contact the weld. When the lifting plate slides vertically, the guide post slides relative to the receiving groove to prevent the lifting plate from rotating with the drive screw.

[0021] Optionally, the first driving component is configured as a telescopic cylinder, which includes a pressure cylinder and a piston rod slidably disposed at one end of the pressure cylinder. One end of the pressure cylinder is rotatably connected to the lifting plate, and one end of the piston rod is rotatably connected to the mounting plate.

[0022] By adopting the above technical solution, one end of the pressure cylinder is rotatably connected to the lifting plate, and one end of the piston rod is rotatably connected to the mounting plate. When the piston rod slides relative to the pressure cylinder, it can drive the mounting plate to slide towards or away from the lifting plate, thereby adjusting the horizontal distance between the grinding plate and the lifting support.

[0023] Optionally, the mounting plate includes a plate body and a bearing rod fixed to one end of the plate body, and the grinding component is sleeved on the bearing rod and rotatably connected to the bearing rod;

[0024] One end of the grinding component is fixed with a first gear, which meshes with a second gear. The second gear is rotatably mounted on the mounting plate, and the first drive source is used to drive the second gear to rotate.

[0025] By adopting the above technical solution, the grinding part is rotatably mounted on the support rod, realizing the rotatable connection of the grinding part on the mounting plate. The first drive source drives the second gear to rotate, which in turn drives the first gear to rotate, thereby indirectly driving the grinding part to rotate for grinding operations.

[0026] Optionally, the positioning mechanism includes a first positioning component and a second positioning component. The first positioning component includes two first positioning blocks and a second driving member. The two first positioning blocks are arranged opposite to each other, and the second driving member is used to drive the two first positioning blocks to slide.

[0027] The second positioning component includes two second positioning blocks and a third driving member. The two second positioning blocks are arranged opposite to each other, and the third driving member is arranged in a one-to-one correspondence with the second positioning blocks. The second positioning blocks are used to drive the second positioning blocks to slide.

[0028] By adopting the above technical solution, two first positioning blocks are arranged opposite each other. After the aluminum frame is placed on the processing table, the second driving component is activated to drive the first positioning blocks to slide relative to each other until they abut against the side wall of the aluminum frame, thus achieving the positioning of a set of oppositely arranged sides of the aluminum frame on the processing table. Two second positioning blocks are arranged opposite each other, and two third driving components drive the two second positioning blocks to slide relative to each other, so that the second positioning blocks abut against the other side of the aluminum frame, thus achieving the positioning of the other set of oppositely arranged sides of the aluminum frame on the processing table. This positions the aluminum frame in a suitable position on the processing table for easy processing.

[0029] Optionally, a processing bracket is fixed above the processing table, and the second driving component is disposed on the processing bracket;

[0030] The second driving component includes a pneumatic slide, which includes a cylinder and sliders slidably disposed at both ends of the cylinder, and the sliders are connected to the first positioning blocks in a one-to-one correspondence.

[0031] The third driving component includes a positioning cylinder, one end of which has an output rod that slides, and one end of the output rod is connected to the second positioning block.

[0032] By adopting the above technical solution, starting the pneumatic slide can drive the two first sliders to slide relative to each other or away from each other. The first sliders are connected to the first positioning blocks. When the first sliders slide, they can drive the first positioning blocks to slide, so as to realize the positioning function of the first positioning component. The third driving component drives the second positioning block to slide, so that the two positioning blocks can move towards each other or away from each other, so as to realize the positioning function of the second positioning component.

[0033] Optionally, the processing bracket is provided with a guide groove, the pneumatic slide is slidably connected to the guide groove, and the processing bracket is provided with a fourth drive source, which is used to drive the pneumatic slide to slide.

[0034] By adopting the above technical solution, the fourth drive source drives the pneumatic slide table to move along the guide slide groove, and the two first positioning blocks connected to the pneumatic slide table can move together with the pneumatic slide table along the direction of the guide slide groove. When the grinding component grinds the weld on the side where the first positioning component is positioned, the support base slides along the length of the weld, driving the grinding component to slide along the length of the weld. The fourth drive source drives the pneumatic slide table to move along the guide slide groove, so that the first positioning block moves to be opposite to the grinding part. While the grinding part slides under the drive of the support base, the first positioning block slides together with the grinding part under the action of the pneumatic slide table. The grinding part grinds the weld inside the side of the aluminum frame, and the first positioning block abuts against the outer side wall of the side where the grinding part is working, so as to reduce the interference between the grinding part and the side of the aluminum frame during the grinding process, which may cause deformation of the aluminum frame, thereby improving the quality of the ground product.

[0035] Optionally, a transmission screw is rotatably arranged in the guide groove, and an extension block is provided on the first cylinder, the extension block being slidably arranged in the guide groove;

[0036] The transmission lead screw passes through the extension block and is threadedly connected to the extension block, and the fourth drive source is used to drive the transmission lead screw to rotate.

[0037] By adopting the above technical solution, the fourth drive source drives the transmission screw to rotate, and the extension block that is threadedly connected to the transmission screw slides along the guide groove, thereby driving the first cylinder to slide along the guide groove.

[0038] In summary, this application includes at least one of the following beneficial effects:

[0039] 1. In this application, two grinding parts are rotatably arranged on both sides of the lifting support, and the two grinding heads can grind the two weld seams arranged opposite each other on the aluminum frame at the same time, which effectively improves the grinding efficiency.

[0040] 2. In this application, the height of the grinding component is adjusted by setting a lifting support, and the mounting plate on which the grinding head is installed is also rotatably connected to the lifting plate to adjust the horizontal distance between the grinding head and the lifting support, thereby expanding the grinding range of the grinding head and improving the applicability of a curtain wall aluminum frame grinding device.

[0041] 3. In this application, when the grinding part grinds the weld on the inner side wall of the aluminum frame along the weld length direction, the first positioning block can abut against the outer side wall of the aluminum frame at the working position of the grinding part, so as to reduce the interference between the grinding head and the side of the aluminum frame during the grinding process, which causes deformation of the aluminum frame and helps to improve the quality of the ground product.

[0047] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0048] This application provides a curtain wall aluminum frame grinding device.

[0049] refer to Figure 2 and Figure 3 A curtain wall aluminum frame grinding device includes a processing table 1 and a grinding mechanism and a positioning mechanism disposed on the processing table 1. In this embodiment, the table surface of the processing table 1 is specifically configured as a rectangular surface.

[0050] The grinding mechanism includes a lifting support 2 and a grinding assembly 4 mounted on the lifting support 2. The lifting support 2 includes a support base 21, a lifting plate 22, and a drive assembly 7. A working slide 11 is provided on the processing table 1, and one end of the support base 21 is slidably disposed within the working slide 11. A drive screw 12 is disposed within the working slide 11, passing through the support base 21 and threadedly connected to it. One end of the drive screw 12 passes through the inner wall of the working slide 11 and is rotatably connected to the inner wall of the working slide 11 via a bearing; the other end of the drive screw 12 passes through the inner wall of the working slide 11 and is connected to a second drive source 13. In this embodiment, the second drive source 13 is specifically configured as a second motor, and the output shaft of the second motor is fixedly connected to the drive screw 12. Starting the second motor drives the support base 21 to slide along the working slide 11.

[0051] refer to Figure 3 and Figure 4 The drive assembly 7 includes a height adjustment screw 71 and a third drive source 72 fixedly connected to one end of the height adjustment screw 71. One end of the height adjustment screw 71 is rotatably connected to the support base 21 via a bearing. The end of the height adjustment screw 71 away from the support base 21 passes through the lifting plate 22, and the height adjustment screw 71 is threadedly connected to the lifting plate 22. To prevent the lifting plate 22 from rotating with the height adjustment screw 71, guide rods 24 are also fixed on the support base 21. In this embodiment, two guide rods 24 are specifically provided, and the two guide rods 24 are respectively located on both sides of the height adjustment screw 71. One end of the lifting plate 22 has a receiving groove 221 corresponding to each guide rod 24, and the end of the guide rod 24 away from the support base 21 is slidably disposed in the receiving groove 221. The third drive source 72 is specifically provided with a mounting slot 211 on the lifting base for accommodating the third drive source 72. The third drive source 72 is specifically provided as a third motor. Activating the third motor can drive the lifting plate 22 to slide in the vertical direction.

[0052] refer to Figure 3 and Figure 4The lifting plate 22 is provided with mounting plates 23 for mounting the grinding assembly 4. Specifically, there are two mounting plates 23, located on opposite sides of the lifting plate 22. Each mounting plate 23 includes a plate body 231 and a support rod 232 integrally formed at one end of the plate body 231. The support rod 232 is cylindrical, and the end of the plate body 231 away from the support rod 232 is rotatably connected to the top of the lifting plate 22. In this embodiment, the plate body 231 is hinged to the top of the lifting plate 22 via a hinge.

[0053] refer to Figure 3 The grinding assembly 4 includes a grinding element and a first drive source 42. In this embodiment, the grinding element is specifically configured as a cylindrical grinding head 41. Grinding heads 41 are mounted on two mounting plates 23, and are coaxially sleeved on the support rods 232 of the mounting plates 23, with the grinding heads 41 rotatably connected to the support rods 232. A first gear 43 is fixed to one end of each of the two grinding heads 41, and the first gear 43 is also sleeved on the support rods 232. A second gear 44 meshes with one side of the first gear 43. A rotating shaft 233 is rotatably mounted on the mounting plate 23, and the second gear 44 is coaxially fixed to the rotating shaft 233 to achieve a rotatable connection of the second gear 44 on the mounting plate 23.

[0054] refer to Figure 1 and Figure 4 A first driving component is provided between the mounting plate 23 and the lifting plate 22. Specifically, the first driving component is a telescopic cylinder 3, which includes a pressure cylinder 31 and a piston rod 32 slidably connected within the pressure cylinder 31. The end of the pressure cylinder 31 away from the piston rod 32 is hinged to the lifting plate 22, and the end of the piston rod 32 extends out of the pressure cylinder 31 and is hinged to the mounting plate 23. In this embodiment, two first driving components are specifically provided, and one is connected to each mounting plate 23. When the piston rod 32 slides, it can drive the mounting plate 23 to rotate towards or away from the lifting plate 22. This adjusts the distance between the grinding head 41 and the lifting plate 22, allowing the grinding head 41 to move horizontally to grind the gradually thinning weld seam 91, and also facilitating the grinding head 41 to grind aluminum frames 9 of different sizes.

[0055] In this embodiment, the first drive source 42 is specifically configured as a first motor, which is fixed on the mounting plate 23, and the output shaft of the first motor is fixedly connected to the rotating shaft 233. Starting the first motor will drive the grinding head 41 to rotate under the action of the drive assembly 7 to perform the grinding operation.

[0056] refer to Figure 2 and Figure 4The positioning mechanism includes a first positioning component 5 and a second positioning component 6 disposed on the processing table 1. The first positioning component 5 includes two first positioning blocks 51 disposed opposite to each other. A processing bracket 14 is fixed on the processing table 1, and a second driving component is disposed on the processing bracket 14. The second driving component is specifically configured as a pneumatic slide table 52, which includes a cylinder 521. Both ends of the cylinder 521 are slidably disposed with connecting shafts 523. In this embodiment, two connecting shafts 523 are disposed at intervals on one end of the cylinder 521. A slider 522 is connected to the end of the connecting shaft 523 away from the cylinder 521. There are two sliders 522, and the two sliders 522 are respectively located on both sides of the pneumatic slide table 52. A connecting rod 524 is fixed to the end of the slider 522 that is closer to the processing table 1. The end of the connecting rod 524 that is away from the slider 522 is fixedly connected to the first positioning block 51. The slider 522 and the connecting rod 524 are disposed one-to-one with the first positioning block 51. When the pneumatic slide table 52 drives the two sliders 522 to slide towards or relative to each other, it can drive the two first positioning blocks 51 to slide towards or relative to each other, so that the two first positioning blocks 51 slide to abut against a pair of oppositely arranged sides inside the aluminum frame 9, so as to position the aluminum frame 9 on the processing table 1.

[0057] Reference Figure 2 The second positioning component 6 includes two opposing second positioning blocks 61. A third driving component is provided on one side of each second positioning block 61. The third driving component is specifically a positioning cylinder 62, which is configured in a one-to-one correspondence with each second positioning block 61. An output rod 621 is slidably mounted on the positioning cylinder 62, and one end of the output rod 621 is fixedly connected to the second positioning block 61. The positioning cylinder 62 can drive the two second positioning blocks 61 to slide until they slide to abut against another pair of opposing sides of the aluminum frame 9, thereby enabling the second positioning component 6 to further position the aluminum frame 9.

[0058] Reference Figure 2 and Figure 3 Once the positioning mechanism has positioned the aluminum frame 9 on the processing table 1, the first drive source 42 is activated, causing the mounting bracket to rotate away from the lifting plate 22 until the two grinding heads 41 are aligned with the weld seams 91 on the inner sidewall of the bent section of the aluminum frame 9. Then, the third drive source 72 is activated, driving the lifting plate 22 to descend, causing the grinding heads 41 to contact the weld seams 91. Activating the first drive source 42 again allows the grinding heads 41 to grind the weld seams 91. While the grinding heads 41 are rotating, the second drive source 13 is activated to drive the lifting support 2 to move along the working slide 11, causing the grinding heads 41 to grind the weld seams 91 along their length.

[0059] When the grinding head 41 grinds the weld 91, the thickness of the weld 91 is reduced, so the grinding head 41 needs to continue to shift towards the weld 91. This causes the inner wall of the aluminum frame 9 at the grinding point to be subjected to the pressure of the grinding head 41. The bent part of the aluminum frame 9 is prone to deformation after being compressed.

[0060] refer to Figure 2 and Figure 4 A guide groove 141 is provided on the processing bracket 14, and an extension block 5211 is fixed at one end of the starting slide table parallel to the working slide table 11. The extension block 5211 is slidably disposed within the guide groove 141. A transmission screw 142 is rotatably disposed within the guide groove 141, and the transmission mechanism is arranged along the length direction of the guide groove 141. One end of the transmission screw 142 is fixedly connected to the inner wall of the guide groove 141 via a bearing, and the other end passes through the inner wall of the guide groove 141 and is connected to a fourth drive source 8. In this embodiment, the fourth drive source 8 is specifically configured as a fourth motor. When the grinding head 41 grinds the weld 91 along the length direction of the weld 91, the fourth motor drives the transmission screw 142 to rotate, causing the pneumatic slide table 52 to slide along the guide groove 141; the first positioning block 51 can move simultaneously with the grinding head 41. When the grinding head 41 grinds the weld 91, the first positioning block 51 can abut against the outer wall of the aluminum frame 9 at the grinding location to reduce the possibility of deformation of the aluminum frame 9 under pressure during the grinding process.

[0061] The implementation principle of the aluminum frame grinding device for curtain walls according to this application embodiment is as follows: Two telescopic cylinders 3 are activated, driving two mounting plates 23 to move towards the lifting support 2, so that the aluminum frame 9 to be processed passes through the lifting support 2 and is placed on the processing table 1. The pneumatic slide 52 and positioning cylinder 62 are moved sequentially, driving two first positioning blocks 51 to move towards each other until they abut against two opposite sides of the aluminum frame 9; then, two second positioning blocks 61 are driven to slide towards each other until they abut against the other two opposite sides of the aluminum frame 9, thereby achieving the positioning of the aluminum frame 9 on the processing table 1. Subsequently, the two telescopic cylinders 3 are activated again, driving the mounting plates 23 to rotate away from the lifting support 2, so that the grinding head 41 contacts the weld 91 at the bend of the inner wall of the aluminum frame 9; then, the first drive source 42 is activated, driving the grinding head 41 to rotate for grinding operations.

[0062] When the grinding head 41 rotates, the telescopic cylinder 3 continues to drive the mounting plate 23 to rotate, and the third drive source 72 also continues to drive the lifting support 2 to slide in the vertical direction, so that the grinding head 41 is offset to a certain extent towards the weld 91, so that the grinding head 41 can grind the weld 91 flat.

[0063] The second drive source 13 is activated, driving the lifting support 2 to slide along the working slide 11 to change the working position of the grinding head 41. At the same time, the fourth drive source 8 is activated, driving the pneumatic slide 52 to move simultaneously with the lifting support 2, so that the first positioning block 51 slides simultaneously with the grinding head 41. When the grinding head 41 grinds the weld 91, the first positioning block 51 can abut against the outer wall of the aluminum frame 9 at the grinding location, providing a certain support for the outer wall of the aluminum frame 9, so that the outer wall of the aluminum frame 9 is not easily deformed when subjected to the action of the grinding head 41.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
