[0001] This invention relates to the field of laser cutting, and more specifically, to a lathe structure for cutting metal tubes. Background Technology

[0002] The lathe structure for cutting metal pipes is mainly used for laser cutting and processing of metal pipes. However, when laser cutting metal pipes, it is necessary to manually disassemble the cut pipes and then clamp the new pipes to be cut after each cut. This process is time-consuming and results in low work efficiency.

[0003] For example, the specification of the "Automatic Metal Pipe Cutting Machine" disclosed in Chinese Invention Patent (Application No.: 202311328826.6) states that after the cutting is completed, the machine not only needs to separate the laser cutting head from the metal pipe, but also needs to disassemble the pipe and the mounting base, as well as assemble the mounting base with the new pipe to be cut, which takes too long. The above patent can prove the defects of the prior art.

[0004] Therefore, we have made improvements to this and proposed a lathe structure for cutting metal tubes. Summary of the Invention

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] As described in the background art, when metal cutting devices cut metal pipes, the cut pipes need to be manually disassembled and new pipes to be cut are clamped after cutting, which results in low work efficiency.

[0039] To solve this technical problem, the present invention provides a lathe structure for cutting metal tubes, which is applied to laser cutting.

[0040] For details, please refer to Figures 1-9As shown, the lathe structure for cutting metal pipes specifically includes: a machine body 1, a moving mechanism 101 mounted on the machine body 1, a mounting base 102 mounted on the moving mechanism 101, and a laser head 103 mounted on the mounting base 102. It also includes a rotating mechanism 2 and a fixing mechanism 3 mounted on the machine body 1. In the prior art, the moving mechanism 101 is used to adjust the laser head 103 so that the laser head 103 is aligned with the metal pipe.

[0041] The rotating mechanism 2 includes a motor 201 mounted on the body 1, a drive shaft 202 mounted on the motor 201, a drive gear 203 mounted on the drive shaft 202, a rotating disk 204 mounted on the drive shaft 202, a gear ring 205 mounted on the rotating disk 204, a limiting ring 206 mounted on the rotating disk 204, a synchronous gear 207 mounted on the limiting ring 206, a second motor 208 mounted on the body 1, a transmission shaft 209 mounted on the second motor 208, and a transmission gear 210 mounted on the transmission shaft 209.

[0042] The lathe structure for cutting metal pipes provided by this invention addresses the problem in the prior art where metal cutting devices require manual disassembly of the cut pipes and clamping of new ones after cutting, resulting in low work efficiency. This application, through the setting of a rotating mechanism 2 and a fixing mechanism 3, allows the rotating disk 204 to be rotated after the metal pipe is cut, so that the next metal pipe to be cut can be moved to the working area of ​​the laser head 103, thus achieving continuous cutting work. This reduces the clamping and disassembly time and improves work efficiency.

[0043] The rotating mechanism 2 and the fixing mechanism 3 are set to drive the triangular block 310 to grind the surface of the metal pipe. In this way, the oxide layer and impurities on the surface of the metal pipe are removed, preventing the oxide layer and impurities on the surface of the metal pipe from affecting the cutting of the laser head 103, thereby improving the cutting quality and solving the problem of unstable cutting quality caused by impurities on the surface of the metal pipe in the prior art.

[0044] By using the rotating mechanism 2 and the fixing mechanism 3, the burrs on the cut end of the metal pipe are ground by the triangular block 310, thus removing the burrs. This method reduces the number of subsequent deburring steps, improves work efficiency, and solves the problem of the large amount of subsequent deburring work on the cut end of the metal pipe in the prior art.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a lathe structure for cutting metal pipes has a drive gear 203 and a synchronous gear 207 that are adapted to each other, a gear ring 205 and a transmission gear 210 that are adapted to each other, and a drive shaft 202 and a transmission shaft 209 that are rotatably mounted on the machine body 1.

[0049] When using, insert the metal fitting into the limiting ring 206, such as... Figure 2 As shown, multiple limit rings 206 are arranged in a circular array on the rotating disk 204. Starting motors 201 and 208, as... Figure 6 As shown, motor 1 201 and motor 208 drive transmission shaft 209 and drive shaft 202 to rotate counterclockwise, respectively. At this time, transmission gear 210 on transmission shaft 209 drives gear ring 205 and rotating disk 204 to rotate clockwise, and drive gear 203 on drive shaft 202 drives synchronous gear 207 to rotate clockwise. In this way, the metal tube and rotating disk 204 rotate synchronously, and the metal tube and limiting ring 206 rotate synchronously. After the metal tube is cut, only rotating disk 204 is needed to move the next metal tube to be cut to the working area of ​​laser head 103, which reduces the clamping and disassembly time and improves work efficiency.

[0050] Furthermore, two sets of rotating disks 204 are provided, and both sets of rotating disks 204 are rotatably mounted on the drive shaft 202. The fixing mechanism 3 is mounted on the rotating disks 204. The fixing mechanism 3 includes an adjusting ring 301 rotatably mounted on the limiting ring 206. The adjusting ring 301 is provided with an arc-shaped groove 302. A sliding column 303 is slidably mounted on the arc-shaped groove 302. The limiting ring 206 is provided with a strip-shaped groove 304. A clamping block 305 is slidably mounted on the strip-shaped groove 304. The sliding column 303 is mounted on the clamping block 305.

[0051] The clamping block 305 is used to clamp and fix the metal pipe fitting. When the adjusting ring 301 rotates, the arc groove 302 on the adjusting ring 301 presses the sliding column 303, and the sliding column 303 drives the clamping block 305 to slide along the strip groove 304, so that the clamping block 305 clamps and fixes the metal pipe fitting. In this way, metal pipe fittings of different sizes can be clamped and fixed, improving the practicality of the device.

[0052] Furthermore, multiple clamping blocks 305 are provided, and the multiple clamping blocks 305 are arranged in a circumferential array on the rotating disk 204. A cylinder 306 is provided on the rotating disk 204. The output end of the cylinder 306 is connected to the clamping block 305. The output end of the cylinder 306 drives the clamping block 305 to move along the strip groove 304. The cylinder 306 is used to limit and push the clamping block 305.

[0053] Furthermore, a fixed frame 307 is provided on the body 1, and a synchronous adjustment component 308 is provided on the rotating disk 204. The synchronous adjustment component 308 includes a top moving ring 3081 rotatably disposed on the limit ring 206. The top moving ring 3081 is slidably disposed on the rotating disk 204. A top moving column 3082 is provided on the top moving ring 3081. A spring 3083 is provided on the outside of the top moving column 3082. The two ends of the spring 3083 are disposed on the corresponding surfaces of the rotating disk 204 and the top moving ring 3081. An L-shaped block 3084 is provided on the clamping block 305.

[0054] Furthermore, the synchronizing gear 207 is slidably mounted on the driving gear 203, and the driving gear 203 is used to guide the synchronizing gear 207.

[0055] Furthermore, a sliding groove 3085 is provided on the fixed frame 307, an arc-shaped block 3086 is provided on the sliding groove 3085, and a ball bearing 3087 is rotatably provided on the top moving column 3082. The ball bearing 3087 is slidably provided on the sliding groove 3085 and the arc-shaped block 3086.

[0056] The synchronous adjustment component 308 is provided with a set, such as Figure 4As shown, the synchronous adjustment component 308 is mounted on the right rotating disk 204. When the cylinder 306 on the right rotating disk 204 is activated, it drives the L-shaped block 3084 on the clamping block 305 to press against the inner wall of the metal tube. This cuts the metal tube and fixes it to the L-shaped block 3084. When the L-shaped block 3084 on the right rotating disk 204 is at the bottom of the machine body 1, the ball bearing 3087 slides along the sliding groove 3085 and matches with the arc-shaped block 3086. The arc-shaped block 3086 presses against the ball bearing 3087 and the top moving column. 3082, causing the ball bearing 3087, the pusher column 3082, the limit ring 206 and the pusher ring 3081 to move to the right synchronously. At this time, the cylinder 306 drives the L-shaped block 3084 to release the limit on the cut metal pipe. The cut metal pipe falls from the bottom of the machine body 1. The bottom of the machine body 1 has an existing collection box. The cut metal pipe is collected through the existing collection box. In this way, the height from which the metal pipe falls is reduced, thereby reducing the damage to the metal pipe and improving the quality of the cut metal pipe.

[0057] By using the rotating mechanism 2 and the fixing mechanism 3, once the metal pipe is cut, simply rotate the rotating disk 204 to move the next metal pipe to be cut to the working area of ​​the laser head 103, thus achieving continuous cutting work. This reduces the time for clamping and disassembly and improves work efficiency.

[0058] Example 2 further optimizes the lathe structure for cutting metal tubes provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a transmission groove 309 is provided on the fixed frame 307, a triangular block 310 is slidably provided on the transmission groove 309, an adjusting column 311 is provided on the triangular block 310, and the adjusting column 311 is slidably provided on the fixed frame 307.

[0059] like Figure 6As shown, when motor 1 201 and motor 208 drive transmission shaft 209 and drive shaft 202 to rotate counterclockwise, the transmission gear 210 on transmission shaft 209 drives gear ring 205 and rotating disk 204 to rotate clockwise, and the drive gear 203 on drive shaft 202 drives synchronous gear 207 to rotate clockwise. At this time, the metal tube rotates synchronously along rotating disk 204. The metal tube rotates and rotates clockwise with synchronous gear 207. When the metal tube contacts triangular block 310, the metal tube squeezes triangular block 310 and rotates. The surface of the metal tube is polished by triangular block 310. In this way, the oxide layer and impurities on the surface of the metal tube are removed, preventing the oxide layer and impurities on the surface of the metal tube from affecting the cutting of laser head 103, thereby improving the cutting quality. When the laser head 103 cuts the metal tube, the L-shaped block 3084 fixes the cut metal tube. At this time, the cut metal tube falls and rotates synchronously with the synchronous gear 207. When the cut metal tube contacts the triangular block 310, the cut metal tube squeezes the triangular block 310 and rotates. The triangular block 310 grinds the burrs on the cut end of the metal tube, thus removing the burrs. This method reduces the subsequent deburring steps and improves work efficiency. When the cut metal tube rotates to the bottom of the machine body 1, the triangular block 310 guides the metal tube, so that the cut metal tube slides down the inclined surface of the triangular block 310 when it is automatically discharged. This ensures that the metal tube falls accurately into the existing collection box when it is discharged.

[0060] Furthermore, a second spring 312 is provided on the outside of the adjusting column 311, with the two ends of the second spring 312 respectively located on the transmission groove 309 and the triangular block 310.

[0061] Spring 312 is used to drive the triangular block 310 to reset. When the metal tube squeezes the triangular block 310, the triangular block 310 and the adjusting column 311 slide along the transmission groove 309. Spring 312 is squeezed and deformed. Through spring 312, the three clamping blocks 305 adaptively fit the metal tube to prevent the triangular block 310 from excessively grinding the metal tube.

[0062] Furthermore, the end of the triangular block 310 is wedge-shaped. With this design, when the metal pipe is inserted into the limiting ring 206, the metal pipe squeezes the end of the triangular block 310, thereby preventing the triangular block 310 from interfering with the normal loading and unloading of the metal pipe.

[0063] The rotating mechanism 2 and the fixing mechanism 3 drive the triangular block 310 to grind the surface of the metal pipe. This method removes the oxide layer and impurities on the surface of the metal pipe, preventing the oxide layer and impurities on the surface of the metal pipe from affecting the cutting of the laser head 103, thereby improving the cutting quality. The triangular block 310 grinds the burrs at the cutting end of the metal pipe, thereby removing burrs. This method reduces the subsequent deburring steps and improves work efficiency.

[0064] The lathe structure for cutting metal tubes provided by this invention is used as follows:

[0065] In use, insert the metal pipe into the limiting ring 206, start the cylinder 306, the output end of the cylinder 306 drives the clamping block 305 to move along the strip groove 304, the clamping block 305 drives the sliding column 303 to slide along the arc groove 302, so that the clamping block 305 clamps and fixes the metal pipe. Start motor one 201 and motor two 208, as follows. Figure 6 As shown, motor 1 201 and motor 208 drive transmission shaft 209 and drive shaft 202 to rotate counterclockwise, respectively. At this time, transmission gear 210 on transmission shaft 209 drives gear ring 205 and rotating disk 204 to rotate clockwise, and drive gear 203 on drive shaft 202 drives synchronous gear 207 to rotate clockwise. Thus, the metal tube and rotating disk 204 rotate synchronously, with the metal tube and limiting ring 206 rotating synchronously. After the metal tube is cut, only rotating disk 204 is needed to move the next metal tube to be cut to the working area of ​​laser head 103 for cutting. A set of synchronous adjustment components 308 is provided, such as... Figure 4As shown, the synchronous adjustment component 308 is mounted on the right rotating disk 204. When the cylinder 306 on the right rotating disk 204 is activated, the cylinder 306 drives the L-shaped block 3084 on the clamping block 305 to press against the inner wall of the metal tube. This causes the metal tube to be cut and then fixed to the L-shaped block 3084. At this time, the metal tube rotates clockwise along the rotating disk 204, and the rotation of the metal tube is synchronized with the clockwise rotation of the synchronous gear 207. When the metal tube contacts the triangular block 310, the metal tube presses against the triangular block 310 and rotates, polishing the surface of the metal tube through the triangular block 310. After the laser head 103 cuts the metal tube, the L-shaped block 3084 fixes the cut metal tube. At this time, the cut metal tube falls off and rotates synchronously with the synchronous gear 207. Similarly, when the cut metal tube contacts the triangular block 310... The cut metal pipe is squeezed by the triangular block 310 and rotated. The triangular block 310 grinds the burrs on the cut end of the metal pipe, thus removing the burrs. When the L-shaped block 3084 on the right rotating disk 204 is at the bottom of the machine body 1, the ball 3087 slides along the sliding groove 3085 and matches with the arc block 3086. The arc block 3086 squeezes the ball 3087 and the top column 3082, so that the ball 3087, the top column 3082, the limit ring 206 and the top ring 3081 move to the right synchronously. At this time, the cylinder 306 drives the L-shaped block 3084 to release the limit on the cut metal pipe. The triangular block 310 guides the metal pipe, so that the cut metal pipe slides down the inclined surface of the triangular block 310 when it is automatically discharged, thus ensuring that the metal pipe falls accurately into the existing collection box when it is discharged.
