Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting technology, and in particular to an automatic receiving rack. Background Technology

[0002] In laser tube cutting machine applications, the automatic receiving rack is a crucial auxiliary device. Its main functions include providing follow-up support for the tail of the tube being cut to improve the stability of the cutting process, receiving the cut tubes, and automatically unloading the tubes by tilting and flipping the receiving plate. Existing automatic receiving racks typically use a fixed-position receiving plate design, which to a certain extent meets basic receiving requirements.

[0003] However, with the development of laser tube cutting machine technology, in order to reduce waste of tail material, the front chuck is designed to be able to move short distances, allowing it to be moved in front of or behind the laser cutting head according to cutting requirements. However, because the front and rear positions of the receiving plate of the automatic receiving rack are fixed, a relatively large distance is set between the receiving plate and the front chuck to avoid movement interference between the front chuck and the receiving plate during movement. This results in the receiving plate being unable to effectively receive the cut tube when cutting short pieces. This not only affects the overall efficiency of the equipment but may also lead to instability or damage to the tube during the cutting process.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic receiving rack, which aims to solve the technical problem that the receiving plate cannot change its working position with the front chuck.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic receiving rack includes a base frame, a slide that is slidably mounted on the base frame, a displacement drive mechanism for driving the slide to move back and forth, a bracket fixedly mounted on the slide, a vertical frame that is slidably mounted on the bracket, a receiving plate hinged to the top of the vertical frame, a flipping drive mechanism mounted on the vertical frame and driving the receiving plate to tilt to the side, and a lifting mechanism mounted on the bracket and driving the vertical frame, the receiving plate and the flipping drive mechanism to lift synchronously. The receiving plate is in a horizontal state or a downward tilting state under the drive of the flipping drive mechanism.

[0008] As a further improvement to the above technical solution, the displacement driving mechanism is a first cylinder that is laterally mounted on the base frame, and the piston rod end of the first cylinder is connected to the slide via a transmission block.

[0009] As a further improvement to the above technical solution, the transmission block is provided with a plurality of vertically extending waist-shaped holes, and the slide is provided with threaded holes of the same number as the transmission block and corresponding one-to-one, and the screw passes through the waist-shaped holes and engages with the threaded holes.

[0010] As a further improvement to the above technical solution, the base frame is provided with two first guide rails extending in the front and rear directions, and the bottom of the carriage is provided with a first slider that is slidably connected to the first guide rails.

[0011] As a further improvement to the above technical solution, the lifting mechanism includes a rack vertically mounted on a vertical frame, a reducer mounted on a bracket, a lifting drive motor connected to the input end of the reducer, a transmission shaft connected to the output end of the reducer via a coupling, and a gear sleeved on the transmission shaft; the gear meshes with the rack.

[0012] As a further improvement to the above technical solution, the vertical frame is provided with a vertically extending second guide rail, and the bracket is provided with a second slider that is slidably connected to the second guide rail.

[0013] As a further improvement to the above technical solution, the flipping drive mechanism is a second cylinder, the cylinder body of the second cylinder is hinged to the vertical frame, and the piston rod end of the second cylinder is hinged to the bottom surface of the receiving plate.

[0014] As a further improvement to the above technical solution, the receiving plate is provided with a plurality of slots arranged in the front-to-back direction, and a guide roller is rotatably provided at each slot, the axis of the guide roller extending in the left-to-right direction.

[0015] As a further improvement to the above technical solution, the receiving plate has a flange formed on the side near the hinge point.

[0016] As a further improvement to the above technical solution, a feeding platform for connecting with the receiving plate is provided on one side of the base frame.

[0017] The beneficial effects of this utility model are as follows: Compared with existing automatic receiving racks where the receiving plate is fixed in position and prone to interference with the movable front chuck, leading to difficulties in receiving short materials, the automatic receiving rack provided by this utility model, through the setting of a displacement drive mechanism, can drive the carriage and related components to move back and forth according to the length of the pipe and the position of the front chuck. During normal cutting, the rear end of the receiving plate can be brought closer to the front chuck, shortening the distance between the two and placing the receiving plate in a suitable working position; when the front chuck moves to the front of the laser cutting head, the carriage and components can move forward synchronously to avoid interference, effectively solving the problem of motion interference. It can effectively receive long materials, short materials, and tail materials, improving the applicability of the equipment. Attached Figure Description

Detailed Implementation

[0023] This utility model provides an automatic receiving rack. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0024] Please see Figures 1 to 4 This utility model provides an automatic receiving rack, including a base frame 1, a slide 2 slidably mounted on the base frame 1, a displacement drive mechanism for driving the slide 2 to move back and forth, a bracket 6 fixedly mounted on the slide 2, a vertical frame 5 slidably mounted on the bracket 6, a receiving plate 8 hinged to the top of the vertical frame 5, a flipping drive mechanism mounted on the vertical frame 5 and driving the receiving plate 8 to flip to the side, and a lifting mechanism mounted on the bracket 6 and driving the vertical frame 5, the receiving plate 8 and the flipping drive mechanism to lift synchronously. The receiving plate 8 is in a horizontal state or a downward tilted state under the drive of the flipping drive mechanism.

[0025] In normal cutting conditions, the front chuck is located behind the laser cutting head. At this time, the displacement drive mechanism, based on the length of the tube and the position of the front chuck, drives the carriage 2 and its components to move backward, bringing the rear end of the receiving plate 8 as close as possible to the front chuck, shortening the distance between them, and placing the receiving plate 8 in a suitable working position. During cutting, the lifting mechanism can drive the vertical frame 5, the receiving plate 8, and the tilting drive mechanism to rise and fall synchronously, adjusting the height of the receiving plate 8 according to the height of the tube. This ensures effective follow-up support for the front section of the tube, preventing sagging and affecting cutting accuracy. Whether the tube is short or long, it can be supported by the receiving plate 8 during cutting, preventing deformation and ensuring cutting accuracy. After cutting, the tube is naturally received by the receiving plate 8. The tilting drive mechanism then activates, tilting the receiving plate 8 to the side, changing it from a horizontal to a downward tilting position. The cut tube is then automatically discharged under gravity.

[0026] When only a section of the pipe remains, the front chuck moves forward to the front of the laser cutting head. At the same time, the displacement drive mechanism drives the carriage 2 and the components on the carriage 2 to move forward to avoid the obstruction. However, the rear end of the receiving plate 8 remains close to the front chuck. The receiving plate 8 provides follow-up support for the front section of the pipe. The laser cutting head cuts off the waste material at the rear end of the pipe. Then, the front chuck releases the waste material and moves backward. The waste material is naturally received by the receiving plate 8. The flipping drive mechanism starts to operate, driving the receiving plate 8 to flip to the side, so that the receiving plate 8 changes from a horizontal state to a downward tilting state. The waste material is automatically discharged under the action of gravity.

[0027] Compared to existing automatic receiving racks where the receiving plate 8 is fixed in position and prone to interference with the movable front chuck, leading to difficulties in receiving short materials, the automatic receiving rack provided by this utility model features a displacement drive mechanism. This mechanism allows the slide 2 and related components to move back and forth based on the pipe length and the position of the front chuck. During normal cutting, the rear end of the receiving plate 8 can be brought closer to the front chuck, shortening the distance between them and placing the receiving plate 8 in a suitable working position. When the front chuck moves to the front of the laser cutting head, the slide 2 and its components can move forward synchronously to avoid interference, effectively solving the motion interference problem. This allows for the effective reception of long, short, and tail materials, improving the applicability of the equipment.

[0028] In addition, the lifting mechanism can drive the vertical frame 5, the receiving plate 8, and the tilting drive mechanism to rise and fall synchronously. The height of the receiving plate 8 is adjusted according to the height of the pipe, effectively supporting the front section of the pipe during the cutting process and preventing it from sagging. The receiving plate 8 stably supports the pipe during cutting, preventing deformation and ensuring cutting accuracy, thus improving product quality. When the pipe cutting or tail material cutting is completed, the tilting drive mechanism activates, causing the receiving plate 8 to tilt from a horizontal position to a downward tilting position. The cut pipe and tail material are automatically discharged under gravity, requiring no manual intervention, achieving automated operation, improving work efficiency, and reducing labor intensity.

[0029] When the laser tube cutter cuts a tube, the displacement drive mechanism starts working, which drives the slide 2 to move back and forth on the base frame 1. Based on the length of the tube and the position of the front chuck, the displacement drive mechanism adjusts the position of the slide 2 to place the receiving rack in a suitable working position.

[0030] In practice, since the front chuck only has two states—in front of the laser cutting head and behind it—the receiving plate 8 only needs to switch between the two positions, simplifying the control logic. Therefore, the displacement drive mechanism is a first cylinder 31 horizontally mounted on the base frame 1. The piston rod end of the first cylinder 31 is connected to the slide 2 via a transmission block 32. The first cylinder 31 provides a stable and powerful driving force, quickly responding to changes in the position of the pipe and the front chuck, rapidly driving the slide 2 to move back and forth, enabling timely adjustment of the receiving plate 8's position, meeting the needs of different cutting conditions, ensuring efficient operation of the receiving frame, and simplifying the overall structure of the device.

[0031] Preferably, the transmission block 32 has multiple vertically extending oblong holes 33, and the slide 2 has the same number of threaded holes as the transmission block 32, which are one-to-one corresponding. Screws pass through the oblong holes 33 and engage with the threaded holes. The oblong holes 33 extend vertically, which allows the transmission block 32 to be finely adjusted in a certain range of vertical direction when connected to the slide 2. During the installation of the automatic receiving rack, the initial relative position of the transmission block 32 and the slide 2 may deviate due to factors such as processing errors and assembly errors. Through the oblong holes 33, the installer can easily adjust the vertical position of the transmission block 32 to achieve the optimal connection between the piston rod of the first cylinder 31 and the slide 2, ensuring that the displacement drive mechanism can smoothly drive the slide 2 to move back and forth.

[0032] Furthermore, the base frame 1 is provided with two first guide rails 11 extending front and rear, and the bottom of the slide 2 is provided with a first slider 12 that is slidably connected to the first guide rails 11. The first guide rails 11 provide precise guidance for the front and rear movement of the slide 2, ensuring that the slide 2 moves smoothly in the predetermined front and rear direction under the action of the displacement drive mechanism, avoiding instability such as deviation or shaking of the slide 2, and ensuring that the receiving plate 8 can always accurately reach the required position and maintain a suitable distance from the front chuck, thereby achieving efficient material receiving.

[0033] Specifically, the lifting mechanism includes a rack 41 vertically mounted on the vertical frame 5, a reducer 42 mounted on the bracket 6, a lifting drive motor 43 connected to the input end of the reducer 42, a transmission shaft 44 connected to the output end of the reducer 42 via a coupling, and a gear 45 sleeved on the transmission shaft 44; the gear 45 meshes with the rack 41. The rotation of the lifting drive motor 43 is reduced and amplified by the reducer 42 before being transmitted to the transmission shaft 44, driving the gear 45 to rotate in the forward or reverse direction. Due to the precise tooth profile matching between the gear 45 and the rack 41, the rack 41 will rise or fall a fixed distance accordingly for each rotation of a certain angle. This allows for precise control of the lifting height of the vertical frame 5, the receiving plate 8, and the tilting drive mechanism, enabling the receiving plate 8 to accurately adjust its position according to the actual height of the pipe, providing stable follow-up support for the pipe and ensuring cutting accuracy.

[0034] Furthermore, the vertical frame 5 is provided with a vertically extending second guide rail 46, and the bracket 6 is provided with a second slider 47 that is slidably connected to the second guide rail 46. The second guide rail 46 provides precise guidance for the lifting and lowering movement of the vertical frame 5. When the lifting mechanism drives the vertical frame 5, the receiving plate 8, and the tilting drive mechanism to lift and lower synchronously, the second guide rail 46 ensures that the vertical frame 5 moves smoothly and strictly along the vertical direction, avoiding any forward or backward, left or right deviation or swaying of the vertical frame 5 during the lifting and lowering process. This allows the receiving plate 8 to stably reach the target height, providing reliable follow-up support for the pipe and ensuring the stability and cutting accuracy of the cutting process.

[0035] In this embodiment, the flipping drive mechanism is a second cylinder 7. The cylinder body of the second cylinder 7 is hinged to the vertical frame 5, and the piston rod end of the second cylinder 7 is hinged to the bottom surface of the receiving plate 8. The second cylinder 7 has a fast response speed. When the pipe cutting is completed or the tail material is processed, after the control system issues a command, the second cylinder 7 can react in a short time and drive the receiving plate 8 to flip, which greatly improves the working efficiency of the equipment and reduces the waiting time in the production process.

[0036] Preferably, the receiving plate 8 has multiple slots 81 arranged in the front-to-back direction, and a guide roller 83 is rotatably mounted at each slot 81, with the axis of the guide roller 83 extending in the left-to-right direction. When the cut pipe falls onto the receiving plate 8, the guide roller 83 can rotate with the rolling of the pipe. Compared to the pipe directly contacting and sliding on the plane of the receiving plate 8, the rolling of the guide roller 83 greatly reduces the friction between the pipe and the receiving plate 8. This makes the movement of the pipe on the receiving plate 8 smoother, reduces scratches or wear on the pipe surface caused by friction, and helps to ensure the surface quality of the pipe.

[0037] The receiving plate 8 has a flange 82 formed on the side near the hinge point. When the pipe is cut and falls onto the receiving plate 8, the flange 82 acts as a blocking structure to prevent the pipe from slipping off the side of the receiving plate 8 near the hinge point due to inertia or vibration. Especially when cutting shorter or thinner pipes, these pipes may have a certain impact force and instability when they fall onto the receiving plate 8. The flange 82 can effectively confine them within the receiving plate 8, ensuring that the pipe is safely received and preventing damage or accidents caused by the pipe falling.

[0038] In this embodiment, a feeding platform 9 for connecting with the receiving plate 8 is provided on one side of the base frame 1. When the receiving plate 8 is flipped over to feed the material, the pipe can smoothly roll from the receiving plate 8 onto the feeding platform 9. The pipes are collected uniformly on the feeding platform 9, which facilitates subsequent centralized handling and sorting, and improves the cleanliness of the production site and the efficiency of material management.
