Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy drilling devices, and in particular to a drilling device for aluminum alloy processing. Background Technology

[0002] Aluminum alloys are widely used in aerospace, automotive manufacturing, and mechanical parts industries due to their lightweight, high strength, and good machinability. In particular, drilling aluminum alloy sheets is a common application. A motor drives the drill bit to rotate, which allows drilling into the sheet material, facilitating assembly. During the drilling process, a clamping and positioning structure is usually used to fix the aluminum alloy sheet on the processing table to prevent the sheet from shaking during drilling, effectively improving the stability of the drilling operation.

[0003] However, in actual processing, when the rotating drill bit comes into contact with the aluminum alloy sheet, a large amount of waste chips are generated, which easily leads to a large amount of waste chips splashing on the processing table. The waste chips need to be cleaned up, and some of the waste chips that fall into the groove structure of the processing table are even more difficult to clean, which significantly reduces the convenience of waste material cleaning. Therefore, this application proposes a drilling device for aluminum alloy processing that can prevent waste chips from splashing. Utility Model Content

[0033] Example

[0034] like Figure 1As shown, this utility model proposes a drilling device for aluminum alloy processing, including a processing table 1. A clamping assembly 9 is fixedly installed on the top of the processing table 1. The clamping assembly 9 presses and positions the aluminum alloy sheet to prevent it from shaking during drilling. Several positioning assemblies 3 are fixedly installed on the top of the processing table 1. Each positioning assembly 3 is equipped with a protective cylinder 33 that can be raised and lowered. When the protective cylinder 33 presses against the top of the aluminum alloy sheet, it can press and position the drilling part of the sheet, enhancing the stability of the drilling operation. When the drill bit is inserted into the protective cylinder 33, most of the waste generated during drilling is intercepted in the inner area of ​​the protective cylinder 33, preventing waste from splashing out. On the processing table 1, waste chips are easily cleaned. A slide rail 2 is fixedly installed on the top of the processing table 1, and a slide block 4 is slidably installed on the top of the slide rail 2. A first motor 7 with adjustable height is installed on the slide block 4. The first motor 7 drives the drill bit to rotate, which facilitates drilling of aluminum alloy plates. Through the cooperation between the slide block 4 and the slide rail 2, the horizontal position of the first motor 7 can be easily adjusted. It can be used in conjunction with multiple positioning components 3 on the top of the processing table 1 to realize multi-station processing. When one aluminum alloy plate is drilled, the position of the first motor 7 can be adjusted to start drilling the next plate, which improves processing efficiency.

[0035] like Figure 2 , Figure 3 As shown, in order to clamp and position the aluminum alloy sheet where drilling is required and to enhance the stability of the drilling operation, the positioning component 3 includes two positioning screws 31. The positioning screws 31 are fixedly installed on the top of the processing table 1. A transverse connecting plate 32 is movably installed on each of the positioning screws 31. One end of each of the two transverse connecting plates 32 is fixedly connected to the outer wall of the protective cylinder 33, ensuring that the protective cylinder 33 can be movably installed on the two positioning screws 31. When it is necessary to clamp and fix the aluminum alloy sheet where drilling is required, press the protective cylinder 33 down. After the protective cylinder 33 is in close contact with the upper surface of the aluminum alloy sheet, rotate the nut threaded on the positioning screw 31 downward. The nut limits the transverse connecting plate 32 in the vertical direction, ensuring that the protective cylinder 33 can firmly press and fix the aluminum alloy sheet.

[0036] Furthermore, a cover plate 34 is fixedly installed at the top of the protective cylinder 33. A circular opening 35 is chiseled on the cover plate 34. The cover plate 34 can reduce the size of the opening at the top of the protective cylinder 33 and leave the circular opening 35 to ensure that the drill bit can penetrate into the interior of the protective cylinder 33, thereby reducing the probability of waste chips flying out from the opening at the top of the protective cylinder 33.

[0037] Secondly, a rubber pad 11 is fixedly installed on the top of the processing table 1. When the aluminum alloy plate is placed on the top of the rubber pad 11, the protective cylinder 33 presses the aluminum alloy plate, which increases the friction between the plate and the contact surface of the processing table 1 and improves the stability of the aluminum alloy plate after it is fixed.

[0038] like Figures 1-3 As shown, to facilitate the collection of waste chips, a discharge port 12 is cut into the processing table 1 and the rubber pad 11. When the drill bit penetrates the plate, it enters the discharge port 12, which prevents the drill bit from contacting the processing table 1 and ensures the safety of the processing operation. An internally threaded sleeve 13 is fixedly installed at the bottom of the processing table 1. A waste chip collection bucket 10 is threaded onto the internally threaded sleeve 13. The discharge port 12 is set above the matching waste chip collection bucket 10. When the drill bit is pulled out from the protective sleeve 33, the waste chips inside the protective sleeve 33 pass through the discharge port 12 and then fall into the waste chip collection bucket 10, which facilitates the collection of waste chips. The waste chip collection bucket 10 can be removed from the internally threaded sleeve 13 by rotating it, which makes it easy to pour out the waste chips collected inside and to clean them up.

[0039] like Figure 1 and Figure 5 As shown, in order to facilitate the adjustment of the drill bit height, a frame plate 5 is fixedly installed on the top of the slide block 4, a cylinder 6 is fixedly installed on the frame plate 5, and a bracket is slidably installed on the frame plate 5 and below the cylinder 6. The first motor 7 is fixedly installed on the bracket, and the output end of the cylinder 6 is fixedly connected to the bracket. The cylinder 6 can drive the bracket to move up and down, which facilitates the adjustment of the height of the first motor 7 and makes it easier to drive the drill bit to move up and down.

[0040] like Figure 1 , Figure 5 and Figure 6 As shown, in order to facilitate the lateral adjustment of the first motor 7, a second motor 8 is fixedly installed at one end of the processing table 1. A reciprocating lead screw 81 is fixedly installed at the output end of the second motor 8. A longitudinal connecting plate 41 is fixedly installed at the bottom of the slide block 4. One end of the reciprocating lead screw 81 passes through the longitudinal connecting plate 41 and is threadedly connected to it. When the second motor 8 drives the reciprocating lead screw 81 to rotate, the slide block 4 can be driven to slide stably laterally through the sliding connection between the slide block 4 and the slide rail 2, which facilitates the horizontal adjustment of the first motor 7.

[0041] Secondly, a long strip opening 21 is cut at the top of the slide rail 2. The aforementioned longitudinal connecting plate 41 passes through the long strip opening 21 and is threadedly connected to the reciprocating lead screw 81. When the slide block 4 slides laterally at the top of the slide rail 2, the longitudinal connecting plate 41 moves laterally along the long strip opening 21, ensuring the stability of the slide block 4 when it slides.

[0042] like Figure 1 and Figure 4 As shown, to facilitate the clamping and fixing of aluminum alloy sheets, the clamping assembly 9 includes a U-shaped bracket 91. The U-shaped bracket 91 is fixedly installed on the top of the processing table 1 and on the side away from the slide rail 2. A pressure plate 92 is movably installed on the U-shaped bracket 91. Several limiting screws 93 are threaded on the top of the U-shaped bracket 91. The bottom end of the limiting screw 93 is inserted into the sleeve at the top of the pressure plate 92 and rotated to connect with it. When it is necessary to clamp and fix the aluminum alloy sheet, the pressure plate 92 is pushed down and the limiting screws 93 are rotated down. The limiting screws 93 limit the pressure plate 92 in the vertical direction, ensuring that the pressure plate 92 can firmly press against the top of the aluminum alloy sheet, effectively improving the firmness of clamping and fixing the aluminum alloy sheet. The limiting of the pressure plate 92 by rotating the limiting screws 93 is convenient for operation.

[0043] In this embodiment, the aluminum alloy sheet is first placed on the top of the processing table 1, and the limiting screw 93 is rotated downwards, so that the pressure plate 92 is firmly pressed onto the top of the aluminum alloy sheet, which facilitates the clamping and fixing of the aluminum alloy sheet. Then, the protective cylinder 33 is pushed downwards. When the bottom end of the protective cylinder 33 contacts the upper surface of the aluminum alloy sheet, the nut threaded on the positioning screw 31 is rotated downwards. When the lower surface of the nut is in close contact with the upper surface of the transverse connecting plate 32, the protective cylinder 33 can be firmly positioned on the top of the aluminum alloy sheet. At this time, the part of the aluminum alloy sheet that needs to be drilled is clamped and fixed by the protective cylinder 33, which improves the firmness of the aluminum alloy sheet after clamping and fixing, prevents the sheet from shaking during drilling, and effectively improves the safety of drilling.

[0044] The second motor 8 drives the slide 4 to move laterally. When the first motor 7 and the drill bit move above the protective cylinder 33, the cylinder 6 drives the bracket used to fix the first motor 7 to move downward. During this process, the first motor 7 drives the drill bit to rotate. After the drill bit enters the protective cylinder 33, it begins to drill holes in the aluminum alloy sheet. The debris splashed during drilling is blocked by the protective cylinder 33, which can reduce the amount of debris scattered on the processing table 1. After the drilling operation is completed, the cylinder 6 drives the first motor 7 and the drill bit to move upward, so that the drill bit can be pulled out from the protective cylinder 33. At this time, the debris accumulated inside the protective cylinder 33 passes through the discharge port 12 and finally falls into the debris collection bucket 10, which facilitates the centralized cleaning of debris. The protective cylinder 33 in this application has a simple structure and is easy to adjust and install. It can not only be used as a clamping and fixing structure for aluminum alloy sheets, but also prevents debris from splashing and avoids a large amount of debris from being scattered on the processing table 1. There is no need to clean the surface of the processing table 1, which effectively improves the convenience of waste cleaning.

[0045] The above specific embodiments are merely several optional embodiments of this utility model.
