[0002] Rolls are commonly used tools in metal processing. They are usually made of hard metals, with specific shapes and surface textures, and are used to press metal billets into the required shapes or thicknesses in rolling mills. Rolls play a key role in industrial production, helping to manufacture various metal products, such as steel plates, aluminum foils, etc. A roll drilling device is a device used for drilling holes in the roll track of a rolling mill. Its main function is to drill holes on the surface or the core of the roll, usually for needs such as cooling or heating of the roll.
[0003] During the processing of rolls, it is necessary to open internal holes in the rolls and process the internal holes. Since rolls of various models have different lengths, some rolls are relatively long and some are relatively short. Rolls with short lengths can be drilled with ordinary drill bits, while rolls with relatively long lengths cannot be processed with ordinary internal hole drill bits. Currently, the drill bits for processing rolls cannot be flexibly applied to roll drilling work. The stroke of the tailstock of the lathe tool post is limited. When an ordinary drill bit is clamped to the tailstock of the lathe tool post, the drill bit cannot be operated, which affects the drilling of the roll and reduces the work efficiency.
[0004] Therefore, we propose a roll drilling device to solve the problems mentioned above. Content of the Utility Model

The drill bit assembly 3 is placed on one side of the clamping tooling 2, and the clamping tooling 2 is placed on one side of the lathe tool holder 1. The lathe tool holder 1 is installed on a CW61100B lathe. The drill bit assembly 3 can be fixed on the lathe tool holder 1 through the clamping tooling 2, so that the processing distance between the drill bit assembly 3 and the roll is shortened, which is convenient for subsequent drilling and can be adapted;
[0023] The lathe tool holder 1 includes an installation disc groove 11 and a top plate 12 provided at the upper end of the lathe tool holder 1. Installation bolts 13 are evenly distributed on the surface of the top plate 12. The clamping tooling 2 includes a connecting plate 21 and a connecting sleeve 22 provided on one side of the connecting plate 21. Three groups of fixing bolts 23 are evenly distributed on the surface of the connecting sleeve 22. During assembly, the connecting plate 21 is inserted into the installation disc groove 11 and fixed through the top plate 12 and the installation bolts 13, so that the clamping tooling 2 is fixed on one side of the lathe tool holder 1, which can support the drill bit assembly 3 and shorten the processing distance between the drill bit assembly 3 and the roll, facilitating subsequent drilling.
[0024] A drill bit hole 24 is provided at the center of the connecting plate 21, and a positioning groove 25 is provided on the inner wall of the drill bit hole 24. The drill bit hole 24 is used for the drill bit assembly 3 to be inserted and fixed in cooperation with the fixing bolts 23.
[0025] The drill bit assembly 3 includes an extension rod 31 and an intermediate rod 32 provided at one end of the extension rod 31. A drill bit body 33 for roll drilling is provided at the end of the intermediate rod 32 away from the extension rod 31. The extension rod 31 can be inserted into the drill bit hole 24 and fixed by using the fixing bolts 23, so that the extension rod 31 is fixed in the connecting sleeve 22.
[0026] In this embodiment: Insert the connecting plate 21 into the mounting disc groove 11, and then cooperate with the top plate 12 and the mounting bolts 13 to fix the position of the connecting plate 21, so that the clamping tooling 2 is fixed on the lathe tool turret 1 for use. Then align the extension rod 31 with the drill bit hole 24, insert the extension rod 31 into the drill bit hole 24, and then use the fixing bolt 23 to fix it, so that the extension rod 31 can be fixed in the connecting sleeve 22, reducing the processing distance between the drill bit body 33 and the roll. Then adjust the position of the roll, align the drill bit with the center position of the drill hole, start the lathe, rotate the roll, set the feed speed and stroke of the lathe, and finally perform the roll drill hole processing, achieving the effect of automatically drilling large-sized rolls. The effect of the clamping tooling 2 can meet the requirements of roll drill hole processing, solving the problem that some large-sized rolls cannot be processed using the CW61100B lathe and ordinary drill bits. Using the clamping tooling 2 in cooperation with the lathe replaces manual drilling, effectively improving work efficiency and reducing labor production costs.
[0027] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 4 , a groove 34 is formed on the surface of the extension rod 31, a connecting spring 35 is installed inside the groove 34, and the other end of the connecting spring 35 is connected to a positioning post 36.

[0028] The positioning post 36 is adapted to the positioning groove 25, and can position the position of the extension rod 31, making the position of the extension rod 31 not easily move, which is beneficial for subsequent fixing using the fixing bolt 23, and the operation is simple.
[0029] Two sets of the groove 34, the connecting spring 35 and the positioning post 36 are provided, and are symmetrically distributed about the center line of the extension rod 31 respectively.
[0030] In this embodiment: When inserting the extension rod 31 into the drill bit hole 24, the positioning post 36 can be squeezed, so that the connecting spring 35 is compressed, and the positioning post 36 can slide in the groove 34. When the extension rod 31 continues to move, the positioning post 36 loses the restraint of the inner wall of the drill bit hole 24, and the positioning post 36 can be inserted into the positioning groove 25 under the self-restoring force of the connecting spring 35. At this time, through the cooperation of the positioning post 36 and the positioning groove 25, the position of the extension rod 31 can be positioned, which is beneficial for subsequent fixing using the fixing bolt 23, and the operation is simple.
[0031] Working principle: Insert the connecting plate 21 into the mounting disc groove 11, and then cooperate with the top plate 12 and the mounting bolts 13 to fix the position of the connecting plate 21, so that the clamping tooling 2 is fixed on the lathe tool holder 1 for use. Then align the extension rod 31 with the drill bit hole 24 and insert the extension rod 31 into the drill bit hole 24, which can squeeze the positioning column 36, causing the connecting spring 35 to be compressed. The positioning column 36 can slide in the groove 34, and the positioning column 36 can insert into the positioning groove 25 under the self-restoring force of the connecting spring 35. At this time, the position of the extension rod 31 can be positioned through the cooperation of the positioning column 36 and the positioning groove 25, and then fixed with the fixing bolt 23, so that the extension rod 31 can be fixed in the connecting sleeve 22. The drill bit assembly 3 can be fixed on the lathe tool holder 1 through the clamping tooling 2, reducing the processing distance between the drill bit body 33 and the roll. Then adjust the position of the roll, align the drill bit with the center position of the drill hole, start the lathe, rotate the roll, set the feed speed and stroke of the lathe, and finally perform roll drill hole processing.
