Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy sheet processing technology, and in particular to an AL aluminum alloy sheet deburring processing device. Background Technology

[0002] In the field of aluminum alloy processing, AL aluminum alloy sheets are prone to burrs after processing due to their material properties. If left untreated, this can affect subsequent assembly accuracy and product quality. Traditional deburring methods rely heavily on manual grinding, which is inefficient, difficult to control in terms of precision, and prone to workpiece damage due to improper operation. Existing mechanical grinding equipment suffers from problems such as unstable workpiece fixation, limited grinding range, and inability to adapt to different specifications of aluminum alloy sheets, making it difficult to meet the demands of efficient and precise deburring in mass production. Therefore, there is an urgent need for an AL aluminum alloy sheet deburring device that can achieve stable fixation, flexible adjustment, and efficient grinding to solve the industry's processing pain points.

[0003] Existing technology patent announcement number CN214080621U discloses a deburring device for aluminum alloy doors and windows, including a mounting base with a mounting frame fixed vertically on it. The mounting frame has fixing components for securing the aluminum alloy doors and windows. Both sides of the mounting frame are equipped with deburring devices. Each device includes a first mounting block, a second mounting block, a first lead screw, and a second lead screw. A polishing component is mounted on the second mounting block. The first mounting block slides along the length of the first lead screw, and the second mounting block slides along the length of the second lead screw. The movement in both the horizontal and vertical directions drives the polishing component to process the aluminum alloy doors and windows. A receiving groove is provided at the bottom of the mounting base, and a scraper for cleaning debris is installed within the groove. The aluminum alloy doors and windows are fixed vertically by the fixing components, and then both sides are processed simultaneously by the processing devices on both sides, eliminating the need to flip the aluminum alloy doors and windows, effectively improving the working efficiency of the device.

[0004] Existing technologies achieve burr removal through fixing components and processing devices. However, when using this processing device, the material to be processed needs to be placed vertically for fixing. This processing method is difficult to apply to thinner aluminum alloy sheets and has certain limitations. To address this, we propose an AL aluminum alloy sheet deburring processing device, which solves the problem of inconvenient material fixing and inadequate grinding when using the existing burr processing device for aluminum alloy sheet processing. This improves the flexibility of the device and expands its application range. Summary of the Invention

[0005] The purpose of this invention is to provide an AL aluminum alloy sheet deburring device, which solves the problem mentioned in the background art that the existing deburring devices are not flexible enough and easily lead to inadequate grinding of aluminum alloy sheets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an AL aluminum alloy sheet deburring processing device, including a fixed cover, a sliding groove is provided at the top of the fixed cover, a sliding block is slidably connected inside the sliding groove, a mounting frame is fixedly connected to the bottom of the sliding block, a grinding roller is rotatably installed inside the mounting frame, and a rotary motor is fixedly connected to the shaft end of the grinding roller through a coupling.

[0007] A reciprocating lead screw is threaded through and connected to the middle of the sliding block. Both ends of the reciprocating lead screw are rotatably connected to the inner end wall of the sliding groove via bearing seats. One end of the reciprocating lead screw passes through the sliding groove and is fixedly connected to a servo motor via a coupling. The servo motor is fixedly installed on the outer wall of one end of the fixed cover. The mounting bracket has two threaded rods symmetrically arranged in the middle of its top surface. The bottom ends of the two threaded rods are rotatably connected to the top surface of the mounting bracket through bearing seats. Their top ends pass vertically through the sliding block and are threadedly connected to the sliding block. A positioning nut is threadedly connected to the outer side of the upper end of the threaded rod.

[0008] A pad is fixedly installed below the grinding roller. Two guide rails are fixedly installed on the top surface of the pad. The two guide rails are horizontally symmetrical about the center line of the pad. The two ends of the two guide rails extend at least 40 cm to the outside of the fixed cover. A material support block is slidably installed on the outside of the guide rails. A vacuum chamber is provided at the upper end of the material support block. Several vacuum adsorption holes are opened at the top of the vacuum chamber. A miniature vacuum pump is fixedly installed on the end wall of the material support block.

[0009] The material support block has an adjustment groove on its top surface. An adjustment screw is rotatably installed inside the adjustment groove. A movable support block is threaded to the outside of the adjustment screw. The end of the adjustment screw away from the vacuum pump passes through the adjustment groove and is fixedly fitted with an adjustment handle.

[0010] The fixed cover has a material inlet at one end and a material outlet at the other end. A push-pull handle is fixedly installed on the side of the material support block near the material outlet. There are at least two material support blocks. An observation window is opened on one side of the fixed cover and a PLC controller is fixedly installed thereon.

[0011] This invention relates to a deburring device for AL aluminum alloy sheets. Multiple support blocks are slidably mounted on the outside of a guide rail, with a vacuum chamber at the top of each support block. A miniature vacuum pump mounted on the end wall of each support block allows the bottom surface of the AL aluminum alloy sheet to be adsorbed and fixed onto the support blocks for subsequent grinding. During grinding, a servo motor drives a reciprocating screw to rotate, which in turn moves the sliding block, mounting frame, and grinding roller back and forth synchronously. Combined with the operator's fixation of the support blocks, burrs on the surface of the aluminum alloy sheet can be quickly removed. Compared to traditional manual grinding, this method is not only time-saving and labor-saving but also improves the uniformity of the grinding effect. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an AL aluminum alloy sheet deburring processing device, including a fixed cover 1, a sliding groove 2 at the top of the fixed cover 1, a sliding block 3 slidably connected inside the sliding groove 2, a mounting frame 4 fixedly connected to the bottom of the sliding block 3, a grinding roller 5 rotatably mounted inside the mounting frame 4, a rotary motor 6 fixedly connected to the shaft end of the grinding roller 5 through a coupling, a reciprocating screw 16 passing through and threadedly connected to the middle of the sliding block 3, the two ends of the reciprocating screw 16 being rotatably connected to the inner end wall of the sliding groove 2 through bearing seats, one end of the reciprocating screw 16 passing through the sliding groove 2 and fixedly connected to a servo motor 17 through a coupling, the servo motor 17 being fixedly installed on the outer wall of one end of the fixed cover 1, two threaded rods 18 symmetrically arranged in the middle of the top surface of the mounting frame 4, the bottom ends of the two threaded rods 18 being rotatably connected to the top surface of the mounting frame 4 through bearing seats, their top ends vertically passing through the sliding block 3 and threadedly connected to the sliding block 3, and a positioning nut 19 threadedly connected to the outer side of the upper end of the threaded rod 18.

[0017] The rotary motor 6 drives the grinding roller 5 to rotate, and the servo motor 17 drives the reciprocating screw 16 to rotate, which in turn drives the sliding block 3, the mounting frame 4, and the grinding roller 5 to move back and forth along the sliding groove 2, achieving a repeated grinding effect on the aluminum alloy sheet. Through the cooperation of two threaded rods 18 and positioning nuts 19, when processing aluminum alloy sheets of different thicknesses, the positioning nuts 19 can be rotated to move the threaded rods 18 up and down, which in turn drives the mounting frame 4 and the grinding roller 5 up and down, achieving a fine-tuning effect on the horizontal working height of the grinding roller 5, further expanding the application range of this grinding device.

[0018] A pad 7 is fixedly installed below the grinding roller 5. Two guide rails 8 are fixedly installed on the top surface of the pad 7. The two guide rails 8 are horizontally symmetrical about the center line of the pad 7. The two ends of the two guide rails 8 extend at least 40 cm to the outside of the fixed cover 1. A material support block 9 is slidably installed on the outside of the guide rails 8. A vacuum chamber 10 is provided at the upper end of the material support block 9. Several vacuum adsorption holes 11 are opened at the top of the vacuum chamber 10. A micro vacuum pump 12 is fixedly installed on the end wall of the material support block 9. An adjustment groove 13 is opened on the top surface of the material support block 9. An adjustment screw 1 is rotatably installed inside the adjustment groove 13. 4. The adjusting screw 14 is threaded to the outside of a movable support block 15. The end of the adjusting screw 14 away from the vacuum pump passes through the adjusting groove 13 and is fixedly equipped with an adjusting handle. One end of the fixed cover 1 is the inlet 20 and the other end is the outlet 21. The support block 9 is fixedly equipped with a push-pull handle 22 on the side near the outlet 21. There are no less than two support blocks 9. An observation window 23 is opened on one side of the fixed cover 1 and a PLC controller 24 is fixedly installed thereon. The PLC controller 24 controls the opening and closing of the servo motor 17, the rotary motor 6 and the micro vacuum pump 12.

[0019] The use of multiple material support blocks 9 in conjunction with two guide rails 8 allows workers to easily place aluminum alloy sheets horizontally inside the fixed cover 1, which can then slide left and right for easy loading and unloading. The PLC controller activates the micro vacuum pump 12, creating a negative pressure vacuum inside the vacuum chamber 10, thereby achieving the adsorption and fixation effect of the aluminum alloy sheet, preventing slippage during grinding and ensuring grinding effectiveness. Furthermore, by adjusting the lead screw 14 in conjunction with the movable support block 15, the top support width of the material support block 9 can be finely adjusted by rotating the lead screw 14 when processing aluminum alloy sheets of different widths, further improving the flexibility of the device.

[0020] Working principle: First, one end of the aluminum alloy sheet is placed on a support block 9 close to the discharge port 21, and then pushed towards the discharge port 21. The other end is then placed on a support block 9 close to the inlet port 20. The PLC controller 24 activates the micro vacuum pump 12 to expel air from the vacuum chamber 10 at the top of the support block 9, creating negative pressure. This causes the four corners of the aluminum alloy sheet to be adsorbed and fixed. Then, the operator uses the push-pull handle 22 to push the aluminum alloy sheet along the guide rail 8 into the appropriate grinding position inside the fixing cover 1. The PLC controller 24 then activates the rotary... Rotary motor 6 and servo motor 17 drive the grinding roller 5 to rotate, and servo motor 17 drives the reciprocating screw 16 to rotate, which in turn drives the sliding block 3, mounting bracket 4 and grinding roller 5 to move back and forth along the sliding groove 2 to achieve repeated grinding of aluminum alloy sheet. During the grinding process, the operator holds the push and pull handle 22 tightly to keep the aluminum alloy sheet relatively fixed and avoid back and forth movement. After grinding is completed, the rotary motor 6 and servo motor 17 are turned off, the aluminum alloy sheet is pushed to the discharge port 21, the micro air pump is turned off, and the material support block 9 is reset to start the next round of processing.

[0021] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
