Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy plate processing technology, and specifically to a grinding device for thin-walled aluminum alloy plates. Background Technology

[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry. They are widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries. Among them, thin-walled aluminum alloy plates are widely used in high-end manufacturing due to their lightweight and high strength characteristics. At present, the industry's demand for surface treatment of thin-walled aluminum alloy plates is growing, especially the requirements for surface roughness and flatness are getting higher and higher.

[0003] Among them, CN222038042U discloses an aluminum plate grinding machine, which relates to the field of aluminum plate grinding technology; while the worktable of this utility model has a placement groove on its upper surface and a moving mechanism below the worktable; in this utility model, the motor drives the first rotating shaft to drive the rotating plate to rotate, and the swing rod set at the end of the rotating plate will slide in the swing groove, thereby pushing the swing plate to swing. The connecting block set at the end of the swing plate drives the horizontal plate to move horizontally. When the swing rod rotates 180 degrees, it will rotate to the bottom of the swing groove. When it rotates again, it will push the swing plate back to its original position. When the motor drives the rotating plate to rotate continuously through the first rotating shaft, it can repeatedly push the swing plate to move back and forth. The horizontal plate drives the clamped aluminum plate to move back and forth repeatedly in the placement groove, so that the surface of the aluminum plate is fully ground by the three grinding rollers. No manual adjustment is required by the operator, which is convenient for the operator to operate.

[0004] While the device is easy for workers to operate and improves the convenience of the operation, the aluminum alloy plates already generate a lot of debris during the grinding process. When the aluminum alloy plates are being fed, these debris can easily rub against the aluminum alloy plates on the workbench surface, causing scratches on the surface of the aluminum alloy plates and affecting their quality.

[0005] Therefore, it is necessary to invent a grinding device for thin-walled aluminum alloy plates to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a grinding device for thin-walled aluminum alloy plates, in order to solve the problem that the debris cannot be cleaned up in time, and that the debris is prone to friction with the aluminum alloy plate, causing scratches on the surface of the aluminum alloy plate and affecting the quality of the aluminum alloy plate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for thin-walled aluminum alloy plates, comprising a conveying platform, a grinding platform fixedly connected to the middle of the front side of the conveying platform, multiple sets of grinding rollers arranged on the upper side of the grinding platform, a material collection box fixedly connected to the upper wall of the grinding platform, a material conveying pipe fixedly connected to the lower end of the material collection box, a suction fan fixedly installed at the bottom of the grinding platform, the lower end of the material conveying pipe fixedly connected to the air inlet of the suction fan, and a clamping assembly arranged on the upper side of the grinding platform, the clamping assembly comprising a mounting base, a first hydraulic cylinder, a mounting plate, a second hydraulic cylinder, a connecting rod, a positioning sleeve, a telescopic rod, a clamping plate, and a transmission rod.

[0013] Optionally, the lower ends of both sets of telescopic rods are fixedly connected to clamps, and anti-slip pads are fixedly connected to the surfaces of the two sets of clamps on the same side that are close to each other.

[0014] By adopting the above technical solution, during the up-and-down sliding of the telescopic rod, the two sets of clamps move closer to each other or further apart, and the anti-slip pads prevent the clamps from scratching the surface of the aluminum alloy plate.

[0015] Optionally, the transmission rod is rotatably connected to the telescopic rod and the clamping plate, and the ends of the two sets of transmission rods on the same side away from the telescopic rod are rotatably connected to the lower end of the piston rod in the second hydraulic cylinder on the same side.

[0016] By adopting the above technical solution, during the downward extension of the piston rod in the second hydraulic cylinder, the two sets of transmission rods drive the two sets of telescopic rods to slide downwards. Conversely, when the piston rod in the second hydraulic cylinder retracts inwards, the two sets of transmission rods drive the two sets of telescopic rods to slide upwards.

[0017] Optionally, the upper surface of the conveying platform is fixedly connected with two sets of linear guide rails, and the lower surface of the mounting base is provided with two sets of guide grooves, which are slidably connected to the two sets of linear guide rails respectively.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figures 1 to 5 The grinding device for thin-walled aluminum alloy plates shown includes a conveying platform 1, a grinding platform 4 fixedly connected to the middle of the front side of the conveying platform 1, material feeding racks 5 on both the left and right sides of the grinding platform 4, multiple sets of grinding rollers 41 on the upper side of the grinding platform 4, a material collection box 42 fixedly connected to the upper wall of the grinding platform 4, a material conveying pipe 43 fixedly connected to the lower end of the material collection box 42, a suction fan 44 fixedly installed at the bottom of the grinding platform 4, the lower end of the material conveying pipe 43 fixedly connected to the air inlet of the suction fan 44, and a clamping assembly on the upper side of the grinding platform 4. The clamping assembly includes a mounting base 2, a first hydraulic cylinder 23, a mounting plate 3, a second hydraulic cylinder 31, a connecting rod 32, a positioning sleeve 33, a telescopic rod 34, a clamping plate 35, and a transmission rod 37.

[0036] Among them, a drive module (the drive module is existing technology and will not be described in detail here) is set on the upper surface of the grinding platform 4 in front of the multiple sets of grinding rollers 41. The drive module drives the multiple sets of grinding rollers 41 to rotate synchronously and grind the surface of the aluminum alloy plate.

[0037] During the grinding process, the aluminum alloy plate is clamped by the clamping assembly and moved to the upper side of the grinding roller 41. Multiple grinding rollers 41 work together to grind the aluminum alloy plate. The debris generated during the grinding process falls into the inside of the collection box 42. At the same time, the suction fan 44, the conveying pipe 43 and the collection box 42 work together to suck up the dust, avoiding dust and debris splashing and improving the cleanliness of the surface of the grinding platform 4. The clamping assembly places the aluminum alloy plate on the upper side of the grinding roller 41 for grinding, avoiding the aluminum alloy plate from contacting the surface of the grinding platform 4, and further avoiding wear on the aluminum alloy plate.

[0038] See Figures 4 to 6 Mounting bracket 22 is fixedly connected to the upper surface of mounting base 2. First hydraulic cylinder 23 is fixedly installed at the front end of mounting bracket 22. The lower end of piston rod in first hydraulic cylinder 23 is fixedly connected to the middle of mounting plate 3. Second hydraulic cylinder 31 is fixedly installed on both the left and right ends of mounting plate 3. Connecting rod 32 is fixedly connected to both the left and right ends of mounting plate 3 at the front and rear sides of second hydraulic cylinder 31. Inclined positioning sleeve 33 is fixedly connected to the end of connecting rod 32 away from mounting plate 3. Telescopic rod 34 is slidably connected inside both sets of positioning sleeve 33. Clamping plate 35 is fixedly connected to the lower end of both sets of telescopic rod 34. Anti-slip pad 36 is fixedly connected to the surface of the two sets of clamping plates 35 on the same side that are close to each other. Transmission rod 37 is rotatably connected to the connection between telescopic rod 34 and clamping plate 35. The ends of two sets of transmission rod 37 on the same side that are away from telescopic rod 34 are rotatably connected to the lower end of piston rod in second hydraulic cylinder 31 on the same side.

[0039] Specifically, during the clamping process of the clamping assembly, the piston rod in the second hydraulic cylinder 31 first retracts into the cylinder body. At this time, the two sets of transmission rods 37 work together to make the two sets of telescopic rods 34 slide upward, thereby causing the two sets of clamping plates 35 to unfold to both sides. When the clamping plates 35 move to the upper part of the aluminum alloy plate, the piston rod in the second hydraulic cylinder 31 pushes downward. At this time, the two sets of transmission rods 37 work together to make the two sets of telescopic rods 34 slide downward synchronously, thereby driving the two sets of clamping plates 35 to move inward synchronously to clamp the aluminum alloy plate. The anti-slip pad 36 effectively improves the stability of clamping the aluminum alloy plate and avoids wear on the surface of the aluminum alloy plate.

[0040] See Figure 1 and Figure 4Two sets of linear guide rails 11 are fixedly connected to the upper surface of the conveyor platform 1. Two sets of guide grooves 21 are opened on the lower surface of the mounting base 2. The two sets of guide grooves 21 are slidably connected to the two sets of linear guide rails 11 respectively. Support blocks 12 are fixedly connected to both the left and right ends of the conveyor platform 1. Transmission discs 13 are rotatably connected to the inner side of the two sets of support blocks 12. A conveyor belt 14 is connected between the two sets of transmission discs 13. The mounting base 2 is fixedly connected to the surface of the conveyor belt 14. An electric motor 15 is fixedly installed at the rear end of the right support block 12. The output end of the electric motor 15 is fixedly connected to the axis of the right transmission disc 13.

[0041] In addition, during the feeding process, the electric motor 15, in conjunction with the two sets of transmission discs 13, drives the conveyor belt 14 to rotate clockwise, causing the mounting base 2 to slide to the right, thereby moving the clamping assembly to the far right. At this time, the first hydraulic cylinder 23 pushes the mounting plate 3 downward. When the two sets of second hydraulic cylinders 31 and the clamping plates 35 move to both sides of the aluminum alloy plate, the second hydraulic cylinders 31 are activated, cooperating with the two sets of clamping plates 35 to clamp the aluminum alloy plate. Then, the first hydraulic cylinder 23 lifts the mounting plate 3 upward, moving the aluminum alloy plate to the position above the grinding roller 41. At this time, the electric motor 15 and the two sets of transmission discs 13 cooperate... The conveyor belt 14 rotates counterclockwise, conveying the aluminum alloy plate to the left. When the aluminum alloy plate passes over the surface of the grinding roller 41, multiple sets of grinding rollers 41 grind the aluminum alloy plate in sequence until the aluminum alloy plate moves to the left side of the grinding platform 4. At this time, the clamping assembly places the aluminum alloy plate inside the left feeding rack 5. Then, the electric motor 15, the transmission plate 13 and the conveyor belt 14 work together to move the clamping assembly to the far right again, continue to clamp the unprocessed aluminum alloy plate and grind it, realizing automatic clamping and grinding of aluminum alloy plates, further improving the convenience of operation and reducing the workload of operators.

[0042] The working principle of this utility model is as follows: The aluminum alloy plate is moved to the upper side of multiple grinding rollers 41 for grinding using a clamping assembly. The suction fan 44 and the material conveying pipe 43, together with the collection box 42, collect the powder and debris generated during grinding, avoiding the splashing of debris and dust, effectively improving the cleanliness of the surface of the grinding platform 4, avoiding scratches on the surface of the aluminum alloy plate, and improving product quality. At the same time, the electric motor 15 and the conveyor belt 14 work together to drive the mounting base 2 to slide left and right, thereby adjusting the position of the clamping assembly, and using the clamping assembly to automatically clamp the aluminum alloy plate and move it to the upper side of the grinding platform 4 for grinding. After grinding, the aluminum alloy plate is automatically placed inside the left-side feeding rack 5, effectively improving the automation level of the equipment, reducing the workload of operators, and improving work efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
