Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically a drilling device for alloy sheets. Background Technology

[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry, and are extensively used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. The rapid development of the industrial economy has led to an increasing demand for welded aluminum alloy structural components, which has intensified research on the weldability of aluminum alloys. Aluminum alloys have low density but relatively high strength, exceeding that of high-quality steel. They also have good plasticity, can be processed into various profiles, and possess excellent electrical and thermal conductivity and corrosion resistance. They are widely used in industry. Some aluminum alloys can be heat-treated to obtain good mechanical properties, physical properties, and corrosion resistance.

[0003] When processing alloy sheets, drilling is required. While the position of the drilling device on the existing drilling machine is adjustable, the position of the bottom chip tray is fixed. This prevents the chip tray from being moved and adjusted in real time as needed, causing the chips and impurities generated during drilling to fall outside the chip tray and onto the bottom of the drilling device. When too much chip and impurities accumulate, they can become stuck on some movable parts, making them difficult to move. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a drilling device for alloy plates, which has the advantage of conveniently collecting debris and impurities.

[0005] The objective of this utility model can be achieved through the following technical solution: a drilling device for alloy plates, comprising a worktable, wherein the worktable includes a limiting and fixing mechanism and a drilling mechanism.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 5As shown, a drilling device for alloy plates includes a worktable 2, which includes a limiting and fixing mechanism and a drilling mechanism.

[0025] The limiting and fixing mechanism includes a first mounting plate 31 symmetrically installed on both sides of the worktable 2, a plurality of first drive motors 32, a first lead screw 33, and two symmetrically arranged sliding limiting seats 34 for limiting and fixing the plate 62. Each first mounting plate 31 has a first drive motor 32 symmetrically installed on one side. The worktable 2 has a partition strip 21 at its center. The output shaft of the first drive motor 32 is connected to the first lead screw 33. A first guide rail is also installed between the partition strip 21 of the worktable 2 and the first mounting plate 31. The first guide rail cooperates with the sliding limiting seat 34. The first lead screw 33 is connected to the sliding limiting seat 34.

[0026] The drilling mechanism includes a drive box 4 fixedly connected to one side of the workbench 2. The top of the drive box 4 is provided with a first drive groove 41. A second drive mechanism is installed on the drive box 4. A second sliding seat 42 is slidably arranged on the second drive mechanism. A plurality of first hydraulic cylinders 43 are fixedly connected to the top of the second sliding seat 42. A second mounting plate 44 is installed on the piston rod of the first hydraulic cylinder 43. A lifting motor 45 is installed on the second mounting plate 44. A third mounting plate 46 is fixed on the lifting rod of the lifting motor 45. A third drive motor 47 is installed on one side of the third mounting plate 46. A drilling component 48 is drivenly connected to the output shaft of the third drive motor 47. The drilling component 48 is aligned downwards with the plate material.

[0027] Several second hydraulic cylinders 51 are fixed at the bottom of the second sliding seat 42. A mounting seat 52 is fixed on the piston rod of the second hydraulic cylinder 51. A chip collection platform 53 is detachably connected to the mounting seat 52. The chip collection platform 53 has a chip collection groove 54 for collecting chips.

[0028] The center of the chip-collecting table 53 and the center of the punch 48 are on the same axis, and the chip-collecting table 53 is always located below the plate.

[0029] The sliding limit seat 34 includes a first limit plate 341 and a second limit plate 342. The first limit plate 341 and the second limit plate 342 are respectively located at the top and bottom positions of one side of the sliding limit seat 34. The plate is located between the first limit plate 341 and the second limit plate 342. Several third hydraulic cylinders 61 are installed on the first limit plate 341. A fixing plate 62 is fixed on the piston rod of each third hydraulic cylinder 61. The bottom wall of the fixing plate 62 abuts against the upper surface of the plate. The upper surface of the second limit plate 342 abuts against the lower surface of the plate.

[0030] In this utility model, the perforated part 48 is existing technology.

[0031] With the above structure, by setting two sliding limit seats 34, the sliding limit seats 34 located on both sides of the partition strip 21 are started by the first drive motor 32, which drives the first lead screw 33 to rotate. The first lead screw 33 changes from rotary motion to linear motion, causing the sliding limit seats 34 to move to the left or right. The distance between the two sliding limit seats 34 can be adjusted according to the width of the plate, so that the plate can be placed on the second limit plate 342 of the two sliding limit seats 34. Then, the fixing plate 62 is moved downward by the third hydraulic cylinder 61 to limit and fix the plate. This is beneficial to the good limiting and fixing effect and the firm fixation.

[0032] By setting a second drive mechanism, it is beneficial to drive the second sliding seat 42 to move left or right. At the same time, the first hydraulic cylinder 43 pushes the second mounting plate 44 forward or backward to adjust it to the predetermined drilling position. Then, the lifting motor 45 drives the drilling component 48 to descend. The drilling component 48 is driven by the drive motor to drill holes. In addition to the drilling component 48, a chip-collecting table 53 is also added to the bottom of the second sliding seat 42, which can move synchronously according to the position of the drilling component 48. When the second sliding seat 42 moves left or right, the chip-collecting table 53 located on the second sliding seat 42 is moved to the left or right. Both the drilling component 48 and the chip collection platform 53 on the 42 can move synchronously, so that the drilling component 48 and the chip collection platform 53 are always on the same axis, the chip collection platform 53 is always below the board, and the drilling component 48 is always aligned with the board and located directly above the chip collection platform 53. When the drilling operation is performed, the debris and impurities generated by the drilling component 48 in drilling through holes in the board fall through the through holes into the chip collection groove 54 of the chip collection platform 53 directly below it for collection. This facilitates the collection of impurities and debris generated by drilling, resulting in better collection effect and strong practicality.

[0033] like Figures 1 to 5 As shown, the second drive mechanism includes a second drive motor 71, a second lead screw 72, and a second guide rail 73. The second drive motor 71 is mounted on one side of the drive housing 4. The output shaft of the second drive motor 71 is connected to the second lead screw 72. The second lead screw 72 and the second guide rail 73 are installed in the groove of the first drive groove 41, and a second sliding seat 42 is slidably mounted on the second guide rail 73. The second sliding seat 42 is connected to the second lead screw 72 and is used to drive the second sliding seat 42 to move left or right. By driving the second lead screw 72 to rotate through the second drive motor 71, the second lead screw 72 changes from rotary motion to linear motion, driving the second sliding seat 42 on the second lead screw 72 to move left or right. This facilitates the automatic adjustment and movement of the chip retaining table and the drilling part 48 on the second sliding seat 42, making the operation convenient and quick.

[0034] like Figures 1 to 5 As shown, a third guide rail 81 is also installed on the side of the drive box 4 near the processing table, and the second sliding seat 42 slides in cooperation with the third guide rail 81.

[0035] A third guide rail 81 is also installed on the side of the drive box 4 near the processing table, and the second sliding seat 42 slides in cooperation with the third guide rail 81.

[0036] By setting the third guide rail 81, the second sliding seat 42 is supported and further driven to move to the left or right on the second lead screw 72. This facilitates the automatic adjustment and movement of the chip retention table and the drilling part 48 on the second sliding seat 42, making the operation convenient and quick.

[0037] like Figures 1 to 5 As shown, the mounting base 52 has an annular connecting groove 91, and the chip collection platform 53 has an annular connecting part 92, which is engaged with the annular connecting groove 91. By providing the annular connecting groove 91, when replacing the chip collection platform 53, it can be removed, and the new chip collection platform 53 can be directly inserted into the annular connecting groove 91 through the annular connecting part 92 for engagement, which facilitates easy disassembly and assembly and ensures structural stability.

[0038] like Figures 1 to 5 As shown, the pushing direction of the first hydraulic cylinder 43 is the same as that of the second hydraulic cylinder 51.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
