Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, in particular to a laser cutting device. Background Art

[0002] During the mechanical production process, laser cutting equipment is often used for pipe cutting. However, due to the large shape and volume of the raw materials, if the cutting process relies solely on the cutting part of the laser cutting equipment, the tail of the pipe cannot be supported, which can easily lead to low pipe cutting accuracy and cutting shape errors, thereby affecting the production process and even affecting product quality. Therefore, if the accuracy of the cut product needs to be improved, it is necessary to support the cut end and the end of the pipe to prevent slipping during the cutting process. During the laser cutting process, if a pipe with a polygonal cross-section is encountered, the cutting difficulty increases because the tail end of the pipe is difficult to support, which in turn affects the cutting effect.

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0026] In the process of mechanical equipment processing, many processing steps are involved, so transportation tracks are often set up in the workshop to facilitate equipment transfer.

[0027] See also Figures 1 to 5 As shown, an embodiment of the utility model provides a laser cutting device for cutting pipes, including a cutting part 1, a transfer part 2, and a support part 3; the support part 3 includes a support rail 31 and a clamping device 32 arranged above the support rail 31, and the clamping device 32 is used to fix the end of the cut pipe; the clamping device 32 includes a driving mechanism 321 and a fixing mechanism 322, the driving mechanism 321 is arranged above the support rail 31, and drives the fixing mechanism 322 to move above the support rail 31; the fixing mechanism 322 includes a turntable 3221, the turntable 3221 is connected to the end of the cut pipe, the turntable 3221 is arranged above the driving mechanism 321, and the driving mechanism 321 drives the turntable 3221 to rotate.

[0028] Specifically, the laser cutting device includes a cutting section where a laser cutter is installed to process the pipe, a transfer section that transports the cut pipe, and a support section that supports the raw pipe material. However, since most pipes are steel structures with a large weight, it is difficult to rely solely on the cutting section to fix the pipe during the cutting process. Therefore, a clamping device 32 is provided on the support section to fix the end of the pipe. The clamping device 32 includes a driving mechanism 321 and a fixing mechanism 322. The driving mechanism 321 drives the rotation of the pipe to be processed, and the fixing mechanism 322 fixes the tail end of the pipe to prevent the pipe from moving during the cutting process and affecting the cutting accuracy. The support section is also provided with two parallel support rails 31. The driving mechanism 321 is arranged above the support rails 31, driving the fixing mechanism 322 to rotate and the clamping device 32 to slide on the support rails 31 along the direction of the rail setting. The fixing mechanism 322 is provided with a turntable 3221, and the driving mechanism 321 is connected to the turntable 3221 and is arranged below the turntable 3221. The turntable 3221 is connected to the end of the cutting pipe. The driving mechanism 321 drives the rotation of the turntable 3221, thereby driving the rotation of the cutting pipe to cut the pipe evenly.

[0029] The drive mechanism 321 comprises a first rotating shaft 3211 and a second rotating shaft 3214. The first rotating shaft 3211 is connected to the turntable 3221, driving the turntable 3221 to rotate. One end of the first rotating shaft 3211 is connected to the turntable 3221, while the other end is fitted with a first transmission wheel 3212, which is connected to a first driver 3213 via the first transmission wheel 3212. The first transmission wheel 3212 rotates with the first driver 3213, transmitting power to the first rotating shaft 3211. The rotation of the first rotating shaft 3211 drives the turntable 3221, which is connected to one end of the cutting pipe, driving the pipe to rotate. One end of the second rotating shaft 3214 is fitted with a second transmission wheel 3215, while the other end is fitted with a drive wheel 3216. The second transmission wheel 3215 is connected to a second driver 3217, which drives the clamping device 32 along the direction in which the support rail 31 is positioned. Specifically, the support track 31 is composed of two tracks. A first track 311 is provided on the inner side of one track of the support track 31. A driving wheel 3216 provided at one end of the second transmission device is connected to the first track 311, thereby enabling the clamping device 32 to move along the direction in which the support track 31 is provided. A second driver 3217 is connected to the second transmission wheel 3215, transmitting power to the second rotating shaft 3214. The second rotating shaft 3214 is provided vertically. The driving wheel 3216 at the other end of the second rotating shaft 3214 rotates to achieve power transmission and drive the clamping device 32 to move. The inner side of the first track 311 has a sawtooth structure, and the driving wheel 3216 is a gear. During the rotation of the driving wheel 3216, the driving wheel 3216 engages with the first track 311, thereby enabling the clamping device 32 to move stably on the first track 311.

[0030] A slot 3221a is provided on the turntable 3221. The slot 3221a is located in the middle of the turntable 3221, bisecting the turntable 3221 along its diameter and symmetrically arranged along the diameter. The turntable 3221 includes a support plate 3222, which is connected to the inner side of the pipe to support and secure the pipe. The support plate 3222 is disposed on the slot 3221a and slides on the slot 3221a to provide support for the interior of the pipe. Furthermore, the use of the support plate 3222 effectively secures pipes of various cross-sections. The support plate 3222 slides within the slot 3221a to support the ends of the square pipe.

[0031] The clamping device 32 is provided with a connecting seat 33, which is arranged on the support rail 31 and connected to the driving mechanism 321. When the driving wheel 3216 slides on the first rail 311, the connecting seat 33 set on the support rail 31 slides on the support rail 31, thereby driving the clamping device 32 to move on the support rail 31 along the rail setting direction.

[0032] In order to prevent the first driver 3213 and the second driver 3217 from moving in the process of driving the turntable 3221 and the clamping device 32 to move respectively, thereby affecting the connection stability and movement stability of the clamping device 32 and one end of the pipe, a first mounting seat 3223 is provided to limit the installation position of the first rotating shaft 3211, and a second mounting seat 3224 is provided to limit the installation position of the second rotating shaft 3214, so as to prevent the positions of the first rotating shaft 3211 and the second rotating shaft 3214 from changing during operation, thereby affecting the cutting accuracy of the pipe.

[0033] The embodiment provided by the present invention connects one end of the pipe to be processed, fixes the position of the pipe, drives the pipe to rotate and / or moves along the direction set by the support track 31, and thus can achieve precise cutting of the pipe.

[0034] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention that fall within the scope of the appended claims and their equivalents.
