[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3A device for quickly positioning and drilling the center hole of a stainless steel pipe includes a base 1. A housing 2 is fixedly connected to both ends of the top of the base 1. A positioning assembly 3 is installed inside the housing 2. The positioning assembly 3 includes a connecting rod 301, a first positioning wheel 302, a second positioning wheel 303, a spring 304, a drive cylinder 305, a movable plate 306, a connecting shaft 307, a slider 308, and a third positioning wheel 309. Connecting rods 301 are installed on both inner walls of the housing 2. The first positioning wheel 302 is installed at the top of the connecting rod 301, and the second positioning wheel 303 is installed at the bottom of the connecting rod 301. A spring 304 is installed between the two connecting rods 301. A drive cylinder 305 is installed at the bottom of the base 1. A movable plate 306 is installed on the output shaft of the drive cylinder 305. Connecting shafts 307 are installed at both ends of the top of the movable plate 306. A slider 308 is installed at the top of the connecting shaft 307, and a third positioning wheel 309 is installed at the top of the slider 308.

[0024] The stainless steel tube is placed on top of the two housings 2, so that the tube is located inside the positioning component 3. By setting the positioning component 3, the stainless steel tube can be positioned, stainless steel tubes of different sizes can be fixed, and the central axis of stainless steel tubes of different sizes can be kept consistent.

[0025] Please see Figures 1 to 3 The outer side of the connecting rod 301 is rotatably connected to the inner wall of the housing 2. The two sides of the positioning wheel 302 are rotatably connected to the top of the connecting rod 301. The two sides of the positioning wheel 303 are rotatably connected to the bottom of the connecting rod 301. The two ends of the spring 304 are fixedly connected to the outer sides of the two connecting rods 301 respectively. The top of the driving cylinder 305 is fixedly connected to the bottom of the base 1. The bottom of the movable plate 306 is fixedly connected to the output shaft of the driving cylinder 305. The bottom of the connecting shaft 307 is fixedly connected to the top of the movable plate 306. The bottom of the slider 308 is fixedly connected to the top of the connecting shaft 307. The two sides of the slider 308 are in contact with the positioning wheel 303. The two sides of the positioning wheel 309 are rotatably connected to the top of the slider 308.

[0026] By activating the drive cylinder 305, the movable plate 306 is pushed upward, which in turn drives the connecting shaft 307 and the slider 308 to move upward. This causes the positioning wheel 309 to move upward and contact the bottom of the stainless steel tube. As the slider 308 moves upward, it pushes the positioning wheels 303 at both ends, causing the connecting rod 301 to rotate on the inner wall of the housing 2. This causes the positioning wheel 302 to move towards the stainless steel tube, and finally causes the two positioning wheels 302 to fit against the two sides of the stainless steel tube, thus positioning the stainless steel tube.

[0027] Please see Figure 1 and Figure 4The base 1 has a drilling device 4 on its top, and the output shaft of the drilling device 4 is fixedly connected to a drilling head 5. The base 1 also has a moving assembly 6 on its top. The moving assembly 6 includes a mounting plate 601, a screw 602, a bracket 603, a guide rail 604, and a throttle 605. There are two mounting plates 601, with the bottom end of the mounting plate 601 fixedly connected to the top end of the base 1. The two ends of the screw 602 are rotatably connected to the outer sides of the two mounting plates 601 respectively. The bottom of the bracket 603 is threadedly connected to the outer side of the screw 602, and the inner wall of the bracket 603 is fixedly connected to the outer side of the drilling device 4. There are two guide rails 604, with the bottom end of the guide rail 604 fixedly connected to the top end of the base 1 and the outer side of the guide rail 604 slidably connected to the inner wall of the bracket 603. One end of the throttle 605 is fixedly connected to one end of the screw 602.

[0028] The moving component 6 can drive the drilling device 4 and the drilling head 5 to move horizontally, so that the drilling head 5 moves toward the stainless steel pipe and drills a hole in the center of the stainless steel pipe. By rotating 605, 602 can be rotated, which can drive 603 to move horizontally, and then drive 4 and 5 to move horizontally. When 603 moves, the guide rail 604 can increase the stability.

[0029] In this invention, the working principle of the device is as follows:

[0030] In use, the stainless steel tube is placed on top of the two housings 2, so that the tube is located inside the positioning assembly 3. By starting the drive cylinder 305, the movable plate 306 is pushed upward, which in turn drives the connecting shaft 307 and the slider 308 to move upward. This causes the positioning wheel 309 to move upward and contact the bottom of the stainless steel tube. During the upward movement of the slider 308, the positioning wheels 203 at both ends can be pushed, which causes the connecting rod 301 to rotate on the inner wall of the housing 2. This causes the positioning wheel 302 to move towards the stainless steel tube. Finally, the two positioning wheels 302 are brought into contact with the two sides of the stainless steel tube, thus positioning the stainless steel tube. This method can fix stainless steel tubes of different sizes and keep the central axis of stainless steel tubes of different sizes consistent.

[0031] After the stainless steel pipe is fixed, the screw 602 is rotated by turning the handle 605, which in turn drives the bracket 603 to move horizontally, thereby driving the drilling device 4 and the drilling head 5 to move horizontally, so that the drilling head 5 moves toward the stainless steel pipe and drills a hole in the center of the stainless steel pipe.
