Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a three-exchange tabletop gantry laser cutting machine. Background Technology

[0002] Laser cutting, as a new type of thermal cutting technology, has advantages such as fast cutting speed, high production efficiency, good cutting surface quality, small heat-affected zone and environmental protection. It has become one of the main cutting methods and is being used more and more widely. At present, exchange table laser cutting machines generally have double exchange tables, with material fed in from the tail and discharged from the tail. The loading and unloading are on one side, and the production cannot be streamlined.

[0003] Common desktop gantry laser cutting machines only include the function of dual exchange tables, which can feed materials in and out from the tail end, but lack the function of continuous flow. This cannot guarantee the smoothness and efficiency of cutting and processing. It is easy for materials to be fed in and out from the tail end, with loading and unloading on one side, which makes it impossible to achieve continuous flow in production and affects the smoothness and efficiency of cutting and processing.

[0004] Therefore, in response to the lack of a continuous flow function in the aforementioned tabletop gantry laser cutting machine, the inability to operate the loading and unloading and cutting processes in parallel, the waiting gaps in the production cycle, the increased equipment idle rate, and the problems that restrict processing efficiency and production line continuity, there is an urgent need to design a new type of three-exchange tabletop gantry laser cutting machine. Utility Model Content

[0005] To overcome the common problems of lack of flow control in tabletop gantry laser cutting machines, such as the inability to perform loading and unloading and cutting processes in parallel, resulting in waiting gaps in production cycle time, increased equipment idle rate, and constraints on processing efficiency and production line continuity.

[0006] The technical solution of this utility model is as follows: a three-exchange tabletop gantry laser cutting machine, including a ground-rail gantry laser cutting machine body; it also includes an electric track, a raising platform, a support frame, a sliding frame, a sliding track, a sliding plate, a lifting plate, and a cylinder. Two electric tracks are symmetrically arranged on the front and rear sides below the ground-rail gantry laser cutting machine body. A raising platform is arranged at the bottom of the electric tracks. Two support frames are symmetrically arranged on the left and right sides of the two raising platforms. A sliding frame is arranged on one side of the top of the support frame. Two sliding tracks are arranged on one side of the sliding frame. A sliding plate is arranged on one side of the sliding track. A lifting plate is arranged on one side of the sliding plate. A cylinder is arranged inside the support frame.

[0007] Preferably, the sliding plate is driven upward by a cylinder, and the sliding plate lifts the cutting table located on the first-station drive frame via a lifting plate. Then, the material is cut by the laser cutting machine body on the ground rail gantry. At the same time, the drive chain roller group on the third-station drive frame drives the cutting table on the third-station drive frame to move towards the second-station drive frame until the cutting table on the third-station drive frame moves onto the first-station drive frame. Then, the drive chain roller group on the first-station drive frame drives the cutting table that moved from the third-station drive frame to the second-station drive frame. At this time, the material is loaded onto the top of the cutting table on the second-station drive frame. After the material on the cutting table on the lifting plate is cut, the sliding plate is driven downward by the cylinder. The sliding plate moves the cutting table back onto the first-station drive frame via the lifting plate. Then, the first-station drive frame moves the unloaded cutting table to the third-station drive frame via the drive chain roller group. The second-station drive frame then moves the fully loaded cutting table to the top of the first-station drive frame via the drive chain roller group. This process repeats, achieving a streamlined workflow. This addresses the common problem of tabletop gantry laser cutting machines, which only have a dual-exchange table function, allowing material to be fed in and discharged from the tail end, but lack a streamlined workflow function. This makes it difficult to guarantee the smoothness and efficiency of cutting and processing, and it is easy for materials to be fed in and discharged from the tail end, with loading and unloading on one side, resulting in a lack of a streamlined workflow and affecting the smoothness and efficiency of cutting and processing.

[0008] Preferably, the front and rear ends of the bottom of the ground rail gantry laser cutting machine body are slidably connected to two electric rails, and the ground rail gantry laser cutting machine body is driven to move left and right through the two electric rails to change the cutting trajectory.

[0009] Preferably, the sliding plate is slidably connected to the sliding rail, and the output end of the cylinder passes through the support frame and is connected to the sliding plate. The cylinder drives the sliding plate to move upward, and the sliding plate lifts the cutting table located on the drive frame of the first station upward through the lifting plate.

[0010] Preferably, a first-station drive frame is set in the middle of the two raised platforms, a second-station drive frame is set to the right of the first-station drive frame, and a third-station drive frame is set to the left of the first-station drive frame, so that the cutting table is supported by the first-station drive frame, the second-station drive frame and the third-station drive frame.

[0011] Preferably, two drive motors are symmetrically arranged at the front and rear ends of the left side inside the first-station drive frame, the second-station drive frame, and the third-station drive frame. The output ends of the six drive motors are respectively connected to drive gears through the first-station drive frame, the second-station drive frame, and the third-station drive frame, and the drive gears are rotated by the drive motors.

[0012] Preferably, drive chain roller sets are provided on the front and rear sides of the top of the first-station drive frame, the second-station drive frame and the third-station drive frame. The drive gear is connected to the drive chain roller set through the chain, and the drive gear drives the drive chain roller set to rotate through the chain.

[0013] Preferably, a cutting table is provided on the top of the four lifting plates and the top of the three-station drive frame, through which materials are loaded.

[0014] The beneficial effects of this utility model are:

[0015] 1. The cylinder drives the sliding plate to move vertically upwards. The sliding plate lifts the cutting table on the first-station drive frame to the processing height via the lifting plate. At this time, the ground rail gantry laser cutting machine body performs cutting operations on the material at the fixed station. Simultaneously, the drive chain roller group of the third-station drive frame is triggered to run. Through the chain transmission mechanism, the empty cutting table on the third-station drive frame is pulled horizontally along the guide rail towards the second-station drive frame until it completely enters the bearing area of ​​the first-station drive frame. Then, the drive chain roller group of the first-station drive frame starts, transferring the cutting table to that station. The cutting table is pushed to the preset loading position of the second-station drive frame. The operator loads the material to be processed onto the top of the table. After the first station is cut, the cylinder reverses and drives the sliding plate to lower and reset the lifting plate and the cutting table, so that the table is re-embedded into the roller conveyor system of the first-station drive frame. At this time, the drive chain roller group of the first-station drive frame starts again and returns the empty table to the third-station drive frame for standby. At the same time, the second-station drive frame transports the fully loaded table to the top of the first-station drive frame for the pre-cutting position through its drive chain roller group, forming a fully closed-loop automated operation cycle.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment: a three-exchange tabletop gantry laser cutting machine, including a ground-rail gantry laser cutting machine body 1; it also includes electric rails 2, raising platforms 3, support frames 4, sliding frames 5, sliding rails 6, sliding plates 7, lifting plates 8, and cylinders 9. Two electric rails 2 are symmetrically arranged on the front and rear sides below the ground-rail gantry laser cutting machine body 1. A raising platform 3 is arranged at the bottom of the electric rails 2. Two support frames 4 are symmetrically arranged on the left and right sides of the two raising platforms 3. A sliding frame 5 is arranged on one side of the top of the support frame 4. Two sliding plates are arranged on one side of the sliding frame 5. The track 6 has a sliding plate 7 on one side and a lifting plate 8 on the other side. A cylinder 9 is installed inside the support frame 4. The cylinder 9 drives the sliding plate 7 to move upwards. The sliding plate 7, via the lifting plate 8, lifts the cutting table 16 located on the first-station drive frame 10. The material is then cut by the ground-rail gantry laser cutting machine body 1. Simultaneously, the drive chain roller group 15 on the third-station drive frame 12 drives the cutting table 16 on the third-station drive frame 12 to move towards the second-station drive frame 11 until the cutting table 16 on the third-station drive frame 12... The material is moved to the first-station drive frame 10, and then the drive chain roller group 15 on the first-station drive frame 10 drives the cutting table 16, which has moved from the third-station drive frame 12, to the second-station drive frame 11. At this time, the material is loaded onto the top of the cutting table 16 on the second-station drive frame 11. After the material on the cutting table 16 on the lifting plate 8 is cut, the sliding plate 7 is driven downward by the cylinder 9. The sliding plate 7 drives the cutting table 16 back to the first-station drive frame 10 through the lifting plate 8. Then, the first-station drive frame 10 drives the unloaded cutting table 16 through the drive chain roller group 15. 6. Move to the three-station drive frame 12. The two-station drive frame 11 then drives the fully loaded cutting table 16 to the top of the one-station drive frame 10 via the drive chain roller group 15. This reciprocating operation realizes the function of flow-through, which solves the problem of common tabletop gantry laser cutting machines that only have the function of double exchange tables, which can feed in from the tail and then discharge from the tail, but lack the function of flow-through. This makes it impossible to guarantee the smoothness and efficiency of cutting and processing. It is easy for materials to be fed in from the tail and then discharged from the tail, with loading and unloading on one side, which makes it impossible to flow-through production and affects the smoothness and efficiency of cutting and processing.

[0023] Please see Figures 2-4In this embodiment, the front and rear ends of the bottom of the ground rail gantry laser cutting machine body 1 are slidably connected to two electric rails 2 respectively. The ground rail gantry laser cutting machine body 1 is driven to move left and right through the two electric rails 2 to change the cutting trajectory. The sliding plate 7 is slidably connected to the sliding rail 6. The output end of the cylinder 9 passes through the support frame 4 and is connected to the sliding plate 7. The cylinder 9 drives the sliding plate 7 to move upward. The sliding plate 7 lifts the cutting table 16 located on the first station drive frame 10 upward through the lifting plate 8. The first station drive frame 10 is set in the middle of the two raised platforms 3. The second station drive frame 11 is set to the right of the first station drive frame 10. The third station drive frame 12 is set to the left of the first station drive frame 10. The first station drive frame 10, the second station drive frame 11 and the third station drive frame 12 support the cutting table 16.

[0024] Please see Figures 1-4 In this embodiment, two drive motors 13 are symmetrically arranged at the front and rear ends of the left side of the first-station drive frame 10, the second-station drive frame 11, and the third-station drive frame 12. The output ends of the six drive motors 13 are respectively connected to drive gears 14 through the first-station drive frame 10, the second-station drive frame 11, and the third-station drive frame 12. The drive gears 14 are driven to rotate by the drive motors 13. Drive chain roller groups 15 are arranged on the front and rear sides of the top of the first-station drive frame 10, the second-station drive frame 11, and the third-station drive frame 12. The drive gears 14 are connected to the drive chain roller groups 15 through chains. The drive gears 14 drive the drive chain roller groups 15 to rotate through chains. Cutting tables 16 are arranged on the top of the four lifting plates 8 and the top of the third-station drive frame 12. The materials are loaded through the cutting tables 16.

[0025] During operation, the cylinder 9 drives the sliding plate 7 to move upward. The sliding plate 7, through the lifting plate 8, lifts the cutting table 16 located on the first-station drive frame 10. Then, the material is cut by the ground rail gantry laser cutting machine body 1. At the same time, the drive chain roller group 15 on the third-station drive frame 12 drives the cutting table 16 on the third-station drive frame 12 to move towards the second-station drive frame 11, until the cutting table 16 on the third-station drive frame 12 moves onto the first-station drive frame 10. Then, the drive chain roller group 15 on the first-station drive frame 10 drives the cutting table 16 that has moved from the third-station drive frame 12 to move. The material is loaded onto the top of the cutting table 16 on the second station drive frame 11. After the material on the cutting table 16 on the lifting plate 8 is cut, the sliding plate 7 is driven downward by the cylinder 9. The sliding plate 7 drives the cutting table 16 back to the first station drive frame 10 through the lifting plate 8. Then, the first station drive frame 10 drives the unloaded cutting table 16 to the third station drive frame 12 through the drive chain roller group 15. The second station drive frame 11 drives the fully loaded cutting table 16 to the top of the first station drive frame 10 through the drive chain roller group 15. This process is repeated to achieve the function of continuous flow.

[0026] Through the above steps, the cylinder 9 drives the sliding plate 7 to move upward. The sliding plate 7, through the lifting plate 8, lifts the cutting table 16 located on the first-station drive frame 10. Then, the material is cut by the ground rail gantry laser cutting machine body 1. At the same time, the drive chain roller group 15 on the third-station drive frame 12 drives the cutting table 16 on the third-station drive frame 12 to move towards the second-station drive frame 11 until the cutting table 16 on the third-station drive frame 12 moves onto the first-station drive frame 10. Then, the drive chain roller group 15 on the first-station drive frame 10 drives the cutting table 16 that moved from the third-station drive frame 12 to the second-station drive frame 11. At this time, the material is loaded onto the top of the cutting table 16 on the second-station drive frame 11. After the material on the cutting table 16 on the lifting plate 8 is cut, the material is removed. The cylinder 9 drives the sliding plate 7 to move downwards. The sliding plate 7, through the lifting plate 8, moves the cutting table 16 back onto the first-station drive frame 10. Then, the first-station drive frame 10, through the drive chain roller group 15, moves the unloaded cutting table 16 to the third-station drive frame 12. The second-station drive frame 11, through the drive chain roller group 15, moves the fully loaded cutting table 16 to the top of the first-station drive frame 10. This process repeats, achieving a streamlined workflow. This solves the problem of common tabletop gantry laser cutting machines, which only have a double exchange table function, allowing material to be fed in and discharged from the tail end, but lack a streamlined workflow function. This makes it difficult to guarantee the smoothness and efficiency of cutting and processing, and it is easy for materials to be fed in and discharged from the tail end, with loading and unloading on one side, making it impossible to achieve a streamlined workflow and affecting the smoothness and efficiency of cutting and processing.
