[0002] The laser engraving machine integrates engraving and cutting functions. It is composed of a platform, a machine head, a machine base, an arm (or rocker arm), a column, a servo drive system, and a command system. When in use, the CAD image is input into the command system, and the command system transmits the image to the servo drive system. The servo drive system controls the machine head to cut a processing track on the sheet metal according to the CAD image. According to the processing track, the machine head will move upward in X, Y, and Z with the tool. To achieve this function, multiple slides are installed on the machine base. The slides are matched on the slide rails and controlled by the servo system. In order to keep the slide normal operation on the slide rail for a long time, so that the servo system can provide instructions normally, and ensure that the lead screw drives the slide to run smoothly, the slide needs to be lubricated regularly.

When the friction wheel follows the machine head and completely reaches the origin, under the action of friction, the driving plate rotates with the protrusion to separate from the lifting wheel, the spring releases its length and pushes the driving rod down through the baffle, the driving rod drives the lifting wheel and the curved part to descend, the curved part drives the oil tank to descend, the bottom surface of the oil tank falls back to the bottom of the sinking cavity, the drop hole is closed, the oil tank no longer drains oil, the equipment is powered off, and no longer lubricated.

[0014] 2. After the engraving machine is used, as each slide returns to the processing origin, lubrication maintenance is automatically completed. The maintenance power comes from the friction when returning to the origin. There is no need to add additional electrical components such as motors, and the drive structure is simple.

DETAILED DESCRIPTION

[0025] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0026] In one embodiment, Figures 1 to 9As shown: This embodiment provides a laser engraving and cutting machine device for sheet metal production, including a column 1, a spreading arm 2 extending in the lateral direction is provided on the column 1, a first slide seat 3 sliding left and right is provided on the spreading arm 2, a second slide seat 4 sliding up and down is provided in front of the first slide seat 3, a machine base 5 is fixed on the second slide seat 4, a machine head 6 is installed on the machine base 5, a carving knife 7 is provided at the bottom end of the machine head 6, a sink cavity 8 is opened downward from the top surface of the machine base 5, an oil tank 9 is provided in the sink cavity 8, and lubricating oil is filled in the oil tank 9, a driving mechanism is provided on the machine base 5, and the driving mechanism includes a transmission shaft 10 installed on the side of the machine head 6, a driving disk 11 is installed on the transmission shaft 10, and an outer circumferential surface of the driving disk 11 is provided with a A protrusion 12 is provided, and the driving mechanism also includes an assembly hole 13 opened on the machine base 5 and a driving rod 14 assembled in the assembly hole 13. A lifting wheel 15 is installed at the bottom end of the driving rod 14. The lifting wheel 15 is close to the driving disk 11 and is located on the rotation trajectory of the protrusion 12. The top end of the driving rod 14 reaches above the top surface of the machine base 5 and is connected to the oil tank 9. A drop hole 16 is opened at the bottom of the oil tank 9, and an immersion hole group 17 is opened from the bottom of the sink cavity 8 to the second slide 4 and the first slide 3. When the bottom surface of the oil tank 9 rises from the bottom of the sink cavity 8, the drop hole 16 is communicated with the immersion hole group 17. When the bottom surface of the oil tank 9 falls back to the bottom of the sink cavity 8, the drop hole 16 and the immersion hole group 17 are closed.

[0027] The immersion hole group 17 includes a row of first immersion hole units 171 opened on the first slide 3, and also includes a row of second immersion hole units 172 opened on the second slide 4. The first immersion hole units 171 are communicated with the slideway on the first slide 3, and the second immersion hole units 172 are communicated with the slideway on the second slide 4. When the bottom surface of the oil tank 9 rises, the lubricating oil not only enters the slideway of the first slide 3 through the first immersion hole units 171, but also enters the slideway of the second slide 4 through the first immersion hole units 171 and the second immersion hole units 172.

[0028] In summary, the present invention only discloses some accessories of the laser engraving machine, such as the workbench. After the above accessories are assembled through the above-mentioned matching relationship, the bottom end of the column 1 is fixed on the workbench. When in use, the sheet metal is fixed on the workbench, and the arm 2 extends most of the accessories to the top of the workbench. The engraving tool 7 is located above the sheet metal, and an image is input into the device. After startup, the servo motor controls the lead screw to drive the first slide 3 to move left and right, and another servo motor controls another lead screw to lift the second slide 4. The clamping mechanism on the workbench drives the sheet metal to move forward and backward. The movement of the first slide 3 and the second slide 4 enables the engraving tool 7 to leave a processing track on the sheet metal according to the image instruction, thereby completing the processing. The servo system controls the movement of the first slide 3 and the second slide 4. After the processing is completed, the servo system controls the first slide 3 and the second slide 4 to return to the processing origin. After the first slide 3 and the second slide 4 return to the processing origin, lubrication maintenance is required. At this time, the driving disk 11 is rotated, and the driving disk 11 rotates with the protrusion 12. Every time the protrusion 12 rotates to contact the lifting wheel 15, it will push the lifting wheel 15 to rise, and the lifting wheel 15 pushes the driving rod 14 and brings the baffle 20 up. The spring 21 is compressed and shortened, and the driving rod 14 pushes the curved part 18 to rise, and the curved part 18 pushes the oil tank 9 to rise. The bottom surface of the oil tank 9 leaves the bottom of the sink cavity 8, and gradually forms a space between the bottom of the sink cavity 8, so that the drop hole 1 6 is opened, and the lubricating oil is discharged from the drop hole 16 and falls into the sink cavity 8, flows from the bottom of the sink cavity 8 to the slope 27, and then flows from the slope 27 to the first immersion hole unit 171, penetrates into the second slide 4 through the second immersion hole unit 172, and enters the slide rail of the second slide 4 to complete lubrication. The second immersion hole unit 172 also includes a part opened on the first slide 3. The lubricating oil will also penetrate into the first slide 3 through the second immersion hole unit 172, and then penetrate into the first immersion hole unit 171 from the first slide 3, so that the slide rail between the first slide 3 and the arm 2 is lubricated. Only when the raised part 12 rotates to contact the lifting wheel 15 can it push the driving rod 14 to rise, and the oil tank 9 can drain the oil once, so as to ensure the intermittent lubrication of the first slide 3 and the second slide 4 and reduce waste.

[0029] like Figure 2 As shown, the top of the driving rod 14 is provided with a bent portion 18, which is bent from the top surface of the machine base 5 and connected to the oil tank 9. When the driving rod 14 rises, the bent portion 18 is used to push the oil tank 9 up, and when the driving rod 14 descends, in addition to using the bent portion 18 to drive the oil tank 9 to descend and reset, the bent portion 18 is also used to fall on the top surface of the machine base 5 after descending, so as to prevent the driving rod 14 from continuing to descend, and ensure that the lifting wheel 15 is always located on the rotation track of the protrusion 12.

[0030] like Figure 7 As shown, the drop holes 16 are arranged in a row and are opened in a rectangular shape along the bottom surface of the oil tank 9. When the oil tank 9 rises, the oil discharge efficiency of the lubricating oil is improved.

[0031] A countersunk hole 19 is opened upward from the bottom end of the assembly hole 13, and a baffle 20 located below the countersunk hole 19 is fixed on the driving rod 14. A spring 21 is sleeved on the driving rod 14, and the bottom end of the spring 21 presses on the baffle 20, and the top end presses on the top end of the countersunk hole 19.

[0032] like Figure 1 As shown, an assembly seat 22 is fixed on the side of the column 1, and the assembly seat 22 extends forward and backward. An assembly rod 23 capable of sliding forward and backward is arranged in the assembly seat 22. The driving mechanism also includes a driving plate 24 fixed at the front end of the assembly rod 23, and the driving plate 24 extends horizontally in the direction of the expansion arm 2. The driving mechanism also includes a friction wheel 25 fixed at the front end of the driving disk 11. When the machine base 5 moves with the machine head 6 toward the direction of the column 1 to the zero-point processing position, the friction wheel 25 contacts the driving plate 24. A screw 26 is fixed at the rear end of the assembly rod 23. When the assembly rod 23 moves forward to the maximum position, the screw 26 rests on the rear end surface of the assembly seat 22. A slope 27 is provided at the bottom of the sinking cavity 8, and the slope 27 gradually tilts downward in the direction of the first immersion hole unit 171.

[0033] After the processing is completed, the first slide 3 and the second slide 4 return to the origin, and the origin is close to the column 1. The tool setting step in the servo control system is completed before the processing. Before the first slide 3 and the second slide 4 return to the origin, the assembly rod 23 is pulled forward to move the drive plate 24 forward until the screw 26 at the rear end of the drive plate 24 is stuck on the rear end of the assembly seat 22. At this time, the forward movement of the assembly rod 23 is limited, and the drive plate 24 is in the straight line position when the friction wheel 25 moves to the left to the origin in advance. When the friction wheel 25 moves toward the left origin position, it moves along the top surface of the drive plate 24 and is rotated by the friction of the top surface of the drive plate 24. The friction wheel 25 rotates the drive disk 11, and the drive disk 11 rotates the protrusion 12. Every time the protrusion 12 rotates to contact the lifting wheel 15, it pushes the lifting wheel 15 to rise, and the lifting wheel 15 pushes the drive rod 1 4 and brings the baffle plate 20 up, the spring 21 is compressed and shortened, the driving rod 14 pushes the bent portion 18 to rise, and the bent portion 18 pushes the oil tank 9 to rise, the bottom surface of the oil tank 9 leaves the bottom of the sink cavity 8, and gradually forms a space between the bottom of the sink cavity 8, so that the drop hole 16 is opened, and the lubricating oil is discharged from the drop hole 16 and falls into the sink cavity 8, flows from the bottom of the sink cavity 8 to the slope 27, and then flows from the slope 27 to the first immersion hole unit 171, penetrates into the second slide 4 through the second immersion hole unit 172, enters the slide rail of the second slide 4, and completes automatic lubrication. The second immersion hole unit 172 also includes a part opened on the first slide 3. The lubricating oil will also penetrate into the first slide 3 through the second immersion hole unit 172, and then penetrate into the first immersion hole unit 171 from the first slide 3, so that the slide rail between the first slide 3 and the extension arm 2 is automatically lubricated. When the friction wheel 25 follows the machine head 6 and completely reaches the origin, under the action of friction, the drive disc 11 rotates with the protrusion 12 to separate from the lifting wheel 15, the spring 21 releases its length and pushes the drive rod 14 down through the baffle 20, the lifting wheel 15 and the curved portion 18 are driven down by the drive rod 14, the oil tank 9 is driven down by the curved portion 18, the bottom surface of the oil tank 9 falls back to the bottom of the sink cavity 8, the drop hole 16 is closed, the oil tank 9 no longer drains oil, the equipment is powered off, and no longer lubricated. After the engraving machine is used, as each slide returns to the processing origin, lubrication maintenance is automatically completed, and the maintenance power comes from the friction when returning to the origin, no additional electrical components such as motors are required, and the drive structure is simple.

[0034] When the processing is completed and no lubrication operation is required, the assembly rod 23 is pushed backward, and the assembly rod 23 moves the driving plate 24 backward. When the friction wheel 25 moves to the left toward the origin, there will be no friction relationship with the driving plate 24, the friction wheel 25 will not rotate, the driving disk 11 will not rotate, the protrusion 12 will not rotate, and will not come into contact with the lifting wheel 15. The lifting wheel 15 will not push the driving rod 14 to rise, the oil tank 9 will not rise, and oil will not be discharged.

[0035] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.
