Abstract
Description
Technical Field
[0001] This invention relates to the field of drilling machine technology, specifically to an automated bolt sleeve drilling machine. Background Technology
[0002] A bolt sleeve is a mechanical part used to strengthen or repair threaded connections. Its core function is to improve the stability, durability, and load-bearing capacity of bolted connections, and it is widely used in machinery manufacturing, construction, automotive, aerospace, and other fields. A bolt sleeve drilling machine is a specialized piece of equipment used to drill holes in bolt sleeves for subsequent installation.
[0003] For example, an existing Chinese patent (CN222133502U) discloses a drilling machine, including a processing table. Columns are connected to the four corners of the bottom of the processing table. A guide rod is connected to the top left side of the processing table. A vertical seat is movably fitted onto the outside of the guide rod. A limiting groove is formed on the right side wall of the vertical seat. A lead screw is rotatably connected within the limiting groove. A lead screw motor is connected to the upper end of the lead screw. A nut seat is screwed onto the outer wall of the lead screw. A lifting platform is connected to the right end of the nut seat. A steering motor is connected to the top right side of the lifting platform.

[0047] In this embodiment, the remaining structure is the same as in Embodiment 1, except that the conveyor belt 402 is replaced by a conveyor chain, and the top surface of the conveyor chain is equipped with magnetic blocks for magnetically attracting the bolts and raw material bars. Compared to the conveyor belt 402, the conveyor chain is more wear-resistant and has a stronger load-bearing capacity, making it suitable for long-term, high-load conveying operations. The magnetic blocks can firmly attract the bolts and raw material bars, preventing them from sliding or falling off during conveying, thus improving the reliability of the conveying process. The conveyor chain is typically made of wear-resistant materials such as high-strength alloy steel, and its link structure undergoes special design and heat treatment processes, resulting in high surface hardness and excellent wear resistance. The link structure of the conveyor chain gives it high strength and rigidity, enabling it to withstand large tensile forces and heavy impacts. Each link can be considered an independent load-bearing unit; through the overall connection of the chain, the load can be evenly distributed across the entire chain, thereby achieving high-load material conveying. The conveyor chain is driven by sprockets, and the meshing transmission between the sprockets and the chain ensures high precision and stability during operation. The teeth of the sprocket and the links of the chain are matched to achieve an accurate transmission ratio, which enables the conveyor chain to run smoothly on straight or curved tracks without the common problems of conveyor belts such as deviation and slippage.
[0048] Furthermore, the conveyor chain exhibits minimal elastic deformation and good tensile strength. Even under prolonged operation and high tensile stress, the length of the conveyor chain changes very little, maintaining stable conveying speed and tension, thus ensuring the normal operation of the conveying system.
[0049] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
