Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, specifically to an automatic feeding device for a laser tube cutting machine. Background Technology

[0002] Laser tube cutting machines are precision devices that use high-energy laser beams to cut tubes. A CNC system controls the laser head to move along a preset trajectory, causing the focused laser to instantly melt or vaporize the tube material. Assisted gas is then used to blow away the molten material, achieving high-precision cutting. Its advantages include fast cutting speed, high precision, and smooth, burr-free cuts. It is widely used in aerospace, automotive manufacturing, medical devices, steel structures, furniture, and kitchen and bathroom products.

[0003] Before cutting and processing, pipes need to be loaded. In the current technology, the loading of lightweight pipes is mostly done manually. However, for the loading of pipes that are long and heavy, multiple people need to work together. This not only results in high labor intensity and slow loading efficiency, but also poses certain safety hazards, which need to be further developed and improved. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for laser tube cutting machines to solve the problems of high labor intensity, low feeding efficiency and prominent safety hazards that exist when manually feeding long and heavy tubes before processing them by laser tube cutting machines.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: An automatic feeding device for a laser tube cutting machine includes a laser tube cutting machine bed body. Several fixed mounting seats are equidistantly arranged on one longitudinal side of the laser tube cutting machine bed body. A tube support frame is arranged on one transverse side of each fixed mounting seat. Two parallel rotating support seats are vertically arranged near one end of each fixed mounting seat close to the laser tube cutting machine bed body. A lifting support mounting plate is arranged at the top of the transverse end of each fixed mounting seat. An upper rotating shaft and a lower rotating shaft are arranged vertically on each rotating support seat. A rotating support plate is arranged on the outer surface of the upper rotating shaft located between the rotating support seats. A first sprocket and a second sprocket are sequentially installed on one end of the upper rotating shaft extending to the outside of the rotating support seat. The lower rotating shaft... A third sprocket is provided at the position corresponding to the second sprocket, extending outward from the outer side of the rotating support base. A rotating mounting shaft is provided at one end of the rotating support plate, and a supporting bearing mechanism is provided at the other end of the rotating mounting shaft. A fourth sprocket is provided at the position corresponding to the first sprocket, and a first transmission chain and a second transmission chain are respectively meshed between the first sprocket and the fourth sprocket, and between the second sprocket and the third sprocket. A lifting support connecting plate is slidably connected to the lifting support mounting plate in the vertical direction on the side closest to the second transmission chain, and a lifting device is provided on the other side. One top end of the lifting support connecting plate is connected to the output end of the lifting device through a connecting block, and the bottom end is connected to the chain eye on the second transmission chain through a chain eye connector.

[0006] Furthermore, the first sprocket, the second sprocket, the third sprocket, and the fourth sprocket all have the same number of teeth and the same spacing.

[0007] Furthermore, the supporting bearing mechanism includes a first rotating bearing plate, which is installed at one end of the rotating mounting shaft. Two fixed supporting rotating seats are provided on one side of the first rotating bearing plate, and a rotating transmission shaft is provided between the fixed supporting rotating seats. One end of the rotating transmission shaft passes through the fixed supporting rotating seats and is fitted with a second rotating bearing plate. A transmission plate is provided between the fixed supporting rotating seats and the rotating transmission shaft. A telescopic device is installed on the side of the first rotating bearing plate that is laterally away from the fixed supporting rotating seats. The output end of the telescopic device passes through the first rotating bearing plate and is hinged to one end of the transmission plate.

[0008] Furthermore, rotary bearings are provided between the upper rotating shaft and the rotary support, between the lower rotating shaft and the rotary support, between the rotary mounting shaft and the rotary support plate, and between the rotary transmission shaft and the fixed support rotary seat.

[0009] Furthermore, both the first rotating bearing plate and the second rotating bearing plate have a protective layer made of polytetrafluoroethylene on their outer surfaces.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the utility model has a reasonable design, simple and stable structure, and strong practicality; through the cooperation of the lifting device and the lifting support connecting plate, the second transmission chain is driven, which in turn drives the upper and lower rotating shafts to rotate. Simultaneously, the rotation of the upper rotating shaft drives the rotating support plate to rotate, and the support bearing mechanism lifts the pipe on the pipe support frame, rotates it along the upper rotating shaft, and sends it to the processing station above the laser tube cutting machine body, realizing automatic feeding operation, significantly reducing manual labor intensity and safety hazards; in the first transmission sprocket, the second transmission sprocket, and the first transmission chain... With the assistance of the drive chain, as the rotating support plate rotates along the upper rotating shaft, it also drives the support bearing mechanism to rotate along the rotating mounting shaft. This ensures that during the rotating support plate's feeding process, the support bearing mechanism is always in a state of lifting the pipe with its opening facing upwards, guaranteeing the stability of the pipe during feeding and preventing it from slipping. In addition, the telescopic device can also drive the rotating transmission shaft to rotate with the assistance of the transmission plate, causing the second rotating bearing plate to rotate accordingly. This allows the pipe to leave the support bearing mechanism after being fed into the processing station, so that the support bearing mechanism can return to its initial position for another pre-feeding operation.

[0019] Combination Figures 1 to 4The automatic feeding device for a laser tube cutting machine shown includes a laser tube cutting machine bed body 1. Several fixed mounting seats 2 are equidistantly arranged on one longitudinal side of the laser tube cutting machine bed body 1. A tube support frame 3 is arranged on one transverse side of each fixed mounting seat 2. Two parallel rotating support seats 4 are vertically arranged near the end of each fixed mounting seat 2 close to the laser tube cutting machine bed body 1. A lifting support mounting plate 5 is arranged on the top of the transverse end of each fixed mounting seat 2. An upper rotating shaft 6 and a lower rotating shaft 7 are arranged vertically on each rotating support seat 4. A rotating support plate 8 is arranged on the outer surface of the upper rotating shaft 6 located between the rotating support seats 4. A first sprocket 9 and a second sprocket 10 are sequentially installed on one end of the upper rotating shaft 6 extending to the outside of the rotating support seat 4. A corresponding lower rotating shaft 7 extends to the outside of the rotating support seat 4. A third sprocket 11 is located at the position of the second sprocket 10. A rotating mounting shaft 12 is located at one end of the rotating support plate 8, and a support bearing mechanism 13 is located at the other end of the rotating mounting shaft 12. A fourth sprocket 14 is located at the position of the first sprocket 9 corresponding to the rotating mounting shaft 12. A first transmission chain 15 and a second transmission chain 16 are respectively meshed between the first sprocket 9 and the fourth sprocket 14, and between the second sprocket 10 and the third sprocket 11. A lifting support connecting plate 17 is slidably connected vertically to the side of the lifting support mounting plate 5 closest to the second transmission chain 16, and a lifting device 18 is located on the other side. One end of the top of the lifting support connecting plate 17 is connected to the output end of the lifting device 18 through a connecting block, and the bottom is connected to the chain eye on the second transmission chain 16 through a chain eye connector.

[0020] The supporting bearing mechanism 13 includes a first rotating bearing plate 1301, which is mounted on one end of a rotating mounting shaft 12. Two fixed supporting rotating seats 1302 are arranged on one lateral side of the first rotating bearing plate 1301, and a rotating transmission shaft 1303 is arranged between the fixed supporting rotating seats 1302. One end of the rotating transmission shaft 1303 passes through the fixed supporting rotating seats 1302 and is fitted with a second rotating bearing plate 1304. A transmission plate 1305 is arranged between the fixed supporting rotating seats 1302 and the rotating transmission shaft 1303. A telescopic device 1306 is installed on the lateral side of the first rotating bearing plate 1301 away from the fixed supporting rotating seats 1302. The output end of the telescopic device 1306 passes through the first rotating bearing plate 1301 and is hinged to one end of the transmission plate 1305. The first rotating support plate 1301 is mounted on the rotating mounting shaft 1303. It forms a rotatable lifting structure with the second rotating support plate 1304 through the fixed support rotating seat 1302, the rotating transmission shaft 1303 and the second rotating support plate 1304. The meshing transmission structure of the first transmission chain 15, the first sprocket 9 and the fourth sprocket 14 ensures that the first rotating support plate 1301 and the second rotating support plate 1304 always maintain a stable lifting posture with the opening facing upward during the material feeding process with the rotating support plate 8, so as to prevent the pipe from slipping. The telescopic device 1306 drives the rotating transmission shaft 1303 through the hinged transmission plate 1305, which can drive the second rotating support plate 1304 to rotate, so that the pipe separates from the support support mechanism 13 after reaching the processing position, which facilitates the reset and cyclic feeding of the support support mechanism 13.

[0021] The first sprocket 9, the second sprocket 10, the third sprocket 11, and the fourth sprocket 14 all have the same number and spacing of teeth. By cooperating with the first transmission chain 15 and the second transmission chain 16, the upper rotating shaft 6, the lower rotating shaft 7, and the rotating mounting shaft 12 maintain the same rotational speed during rotation. When the rotating support plate 8 rotates with the upper rotating shaft 6, the fourth sprocket 14 rotates synchronously with the first sprocket 9 through the first transmission chain 15, driving the rotating mounting shaft 12 and the support bearing mechanism 13 to rotate at the same angular velocity. This ensures that the second rotating bearing plate 1304 always maintains a stable lifting posture with the opening facing upward during the pipe feeding process, eliminating the risk of pipe slippage from the mechanical transmission principle and improving the reliability of the feeding process.

[0022] Rotary bearings are provided between the upper rotating shaft 6 and the rotating support base 4, between the lower rotating shaft 7 and the rotating support base 4, between the rotating mounting shaft 12 and the rotating support plate 8, and between the rotating transmission shaft 1303 and the fixed support rotating base 1302 to ensure smooth rotation of the upper rotating shaft 6, the lower rotating shaft 7, the rotating mounting shaft 12, and the rotating transmission shaft 1303. The outer surfaces of the first rotating bearing plate 1301 and the second rotating bearing plate 1304 are provided with a protective layer made of polytetrafluoroethylene (PTFE). Utilizing its low coefficient of friction and high wear resistance, it effectively reduces contact friction with the pipe, avoiding scratches, indentations, and other damage caused by traditional rigid contact, and ensuring that the surface quality of the pipe is not affected during the feeding process. In addition, the lifting device 18 and the telescopic device 1306 are electrically connected to the control center of the laser pipe cutting machine to control their respective working states. The lifting device 18 and the telescopic device 1306 are either hydraulic cylinders or servo electric cylinders.

[0023] Working principle:

[0024] The pipe to be processed is placed on the pipe support frame in advance. At the same time, the pipe is located inside the first rotating bearing plate and the second rotating bearing plate and is in contact with them to ensure that the support bearing mechanism can accurately lift it. At this time, the lifting device is in the initial position of descent, the rotating support plate is in a horizontal state, and the second rotating support bearing plate is in an inclined state.

[0025] Upon receiving the loading command, the lifting device is activated. The connecting block pulls the lifting support connecting plate upward along the vertical guide rail of the lifting support mounting plate. The chain connector at the bottom of the lifting support connecting plate drives the second transmission chain, which in turn drives the second sprocket and the third sprocket to mesh and rotate, thereby driving the upper rotating shaft and the lower rotating shaft to rotate synchronously (because the sprocket tooth parameters are consistent, the speed is ensured to be the same).

[0026] When the upper rotating shaft rotates, the rotating support plate fixed to its outer surface rotates counterclockwise towards the laser tube cutting machine body around the shaft, synchronously driving the fourth sprocket mounted on the rotating mounting shaft. Through the meshing of the first transmission chain and the first sprocket, the rotating mounting shaft rotates at the same angular velocity as the upper rotating shaft, ensuring that the support bearing mechanism always keeps the openings of the first and second rotating bearing plates facing upwards to support the tube as the support plate rotates—for example, when the support plate rotates 90°, the rotating mounting shaft rotates 90° synchronously, ensuring that the openings of the first and second rotating bearing plates always face upwards to support the tube, preventing tilting or slippage;

[0027] After the supporting bearing mechanism lifts the pipe and rotates it with the rotating support plate to the processing position above the laser pipe cutting machine body, the telescopic device is activated. Its output end drives the transmission plate to rotate around the rotating transmission shaft, causing the second rotating bearing plate to tilt downward, so that the pipe slides along the surface of the first rotating bearing plate to the positioning position of the machine tool, thus completing the loading operation.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
