Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum profile processing, and particularly relates to an aluminum profile drilling device for new energy automobile production and assembly. BACKGROUND

[0002] The new energy automobile refers to an automobile adopting unconventional vehicle fuel as a power source (or using conventional vehicle fuel, adopting a new vehicle power device), and combining advanced technologies of vehicle power control and driving to form an automobile with advanced technical principles and new technologies and structures. At present, in order to reduce the weight of the vehicle as much as possible and improve the cruising range of the vehicle, automobile manufacturers often use aluminum profiles with relatively light weight to assemble some structural frames of the vehicle body. In order to quickly assemble aluminum profiles of various shapes, drilling holes on the surface of the aluminum profile is an essential step. Moreover, for some square tubular aluminum profiles, holes need to be drilled at the same position on each side. If the hole positions on each side are deviated, not only the subsequent installation operation will be seriously affected, but sometimes the driving safety of the automobile will also be affected. In the prior art, a measuring instrument is often used to mark the drilling positions on each side of the square tubular aluminum profile, and then a worker holds a drilling device to drill holes on each side. This not only consumes a lot of time and leads to low processing efficiency, but also the surface of most finished aluminum profiles has been polished, polished, rust-proofed and subjected to many other processes. Therefore, the outer surface is often very smooth. Therefore, the drill bit often moves relative to the surface of the aluminum profile during drilling. This not only seriously affects the drilling precision, but also irreversibly damages the rust-proof layer on the surface of the aluminum profile, thereby causing unnecessary economic losses. SUMMARY

[0047] Embodiment three

[0048] According to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , on the basis of embodiment one, the accurate drilling mechanism 6 comprises a mounting plate 601 fixedly installed on the right side of the workbench 1, a small air pump 602 fixedly installed on the right side of the upper end of the mounting plate 601, an installation cylinder 603 fixedly installed on the left side of the upper end of the mounting plate 601, a rectangular block 604 fixedly installed on the left end of the installation cylinder 603, an avoiding passage 605 formed around the rectangular block 604, a drilling assembly 606 movably installed in the avoiding passage 605, a pushing spring 607 fixedly connected between the bottom of the drilling assembly 606 and the inner wall of the avoiding passage 605, a circular air cavity 608 formed in the rectangular block 604, a marking protrusion 609 fixedly installed on the lower end of the mounting plate 601, the circular air cavity 608 is connected with the inside of the avoiding passage 605, the output end of the small air pump 602 is connected with the inside of the circular air cavity 608, and the small air pump 602 works to inject high-pressure gas into the inside of the avoiding passage 605 through the circular air cavity 608, so that the drilling assembly 606 is in close contact with the inner wall of the aluminum profile pipe 3, and the inner wall drilling operation is completed.

[0049] Specifically, the drilling assembly 606 comprises a rotating seat slidably connected in the avoiding passage 605, a drill bit detachably installed on the upper end of the rotating seat, and a rubber sleeve wrapped outside the rotating seat, the rubber sleeve is in close contact with the inner wall of the avoiding passage 605, in use, the drill bit rotates quickly under the action of the rotating seat, when the high-pressure gas enters the inside of the avoiding passage 605, the rotating seat and the drill bit move towards the outside of the avoiding passage 605 at the same time, and the rapid drilling processing is completed.

In addition, the present embodiment drills from the inside of the aluminum pipe 3 to the outside, so the aluminum chips generated during drilling will fall into the inside of the aluminum pipe 3 and will not splash around, thereby achieving the effect of avoiding damage to the surrounding environment caused by aluminum chips generated during drilling.

During the movement of the drilling assembly 606, the sliding push rod 703 will be contacted and synchronously moved. During the movement of the sliding push rod 703, the rust inhibitor in the inside of the liquid storage tank 701 will enter the inside of the avoiding channel 605 through the liquid drainage tube and the liquid drainage head.
