[0013] As a preferred embodiment of the above technical solution, the cooling pipes are arranged in a linear array at the bottom of the fixed plate, and the first cooling block is fixedly installed on the outer side of the second electric telescopic plate, the outer side of the limiting plate and the outer side of the movable plate, and the second cooling block is fixedly installed on the outer side of the third electric telescopic plate.

[0014] The present invention also provides a process for using the above-described laser cutting and welding apparatus for mold processing, comprising the following steps:

[0015] Step 1: Place the raw material of the mold into the processing equipment and fix it on the processing table. The moving structure causes the connecting seat to move the laser head. At the same time, the first motor drives the rotating rod to rotate along the mounting plate, so that the slider drives the first electric telescopic plate and the limiting structure to move with the laser head. After moving to the appropriate position, the laser head cuts the mold.

[0016] Step Two: When it is necessary to cut a hole of the same size and close proximity to the first hole after the mold is cut, firstly, the cold air inside the storage chamber is delivered downwards through the cold air pipe by the control valve. Through the action of the moving structure, the first motor, the rotating rod, and the slider, the second electric telescopic plate moves back and forth, causing the first electric push rod to drive the first connecting block and the second electric telescopic plate to move, thus cooling the first hole after cutting. Then, the laser head is moved to one side of the first hole after cutting, so that the limiting plate and the movable plate behind the laser head are located at the top of the inner wall of one side of the first hole. The second motor inside the limiting plate behind the laser head is started to drive the threaded rod to rotate along the inner wall of the moving groove. This causes the moving block to move downwards along the inner wall of the moving groove. The push rod deflects and pushes the movable block to move the third electric telescopic plate from the movable opening to the outside of the limiting plate, thereby adjusting according to the size of the hole. Then, the second electric push rod drives the second connecting block, the limiting plate, and the movable block to move downwards simultaneously. By activating the third electric telescopic plate to extend, the second telescopic rod extends, causing the movable plate to move downwards and fit against the bottom inner wall of the first hole. This causes one side of the limiting plate and the movable plate to fit against the inner wall of the first hole. The first cooling block and the second cooling block cool the area for a limited time. Then, the processing equipment is activated to allow the laser head to cut one side of the first hole again.

[0017] Step 3: After the cutting is completed, the third electric telescopic plate moves the movable plate to its original position, and the second electric push rod moves the limiting plate and the movable plate to their original positions. When it is necessary to cut a third hole of the same size and close distance in the horizontal direction of the first hole, when the laser head moves to the horizontal side of the first hole, after adjusting to the appropriate position, the second electric telescopic plate on the right side of the laser head is aligned with the top of the left inner wall of the first hole. Then, the second electric telescopic plate is moved downward by starting, so that its bottom is in contact with the bottom inner wall of the first hole. At the same time, one side of the second electric telescopic plate is in contact with the left inner wall of the first hole for limitation. The first cooling block is used to cool down the area, and then the laser head cuts.

[0018] Step 4: When it is necessary to cut the left side of the second hole and the vertical direction of the third hole again, move the third electric telescopic plate upward to its original position, move the laser head to the position to be cut, so that when the third electric telescopic plate and the movable plate are moved above the second hole, they are opposite to its inner wall. Activate the second electric push rod to move the first connecting block on the right side and the second electric telescopic plate to the inner wall of the left side of the second hole, opposite to it. At the same time, activate the third electric telescopic plate and the second electric telescopic plate to extend the second telescopic rod, so that the bottom of the movable block is attached to the inner wall of the bottom of the second hole, and one side of it is attached to the inner wall of the top of the second hole. The bottom of the second electric telescopic plate is attached to the inner wall of the bottom of the second hole, and to its left inner wall. After cooling by the first cooling block and the second cooling block, the laser head can then cut.

[0019] Step 5: After cutting, conduct a comprehensive inspection of the cutting quality of the laptop mold parts, deburr and clean them, thoroughly clean the mold to be welded, and then weld them using the welding device.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) The present invention can fit and limit the inner wall of one side of the adjacent hole by moving the second electric telescopic plate, the limiting plate and the movable plate. At the same time, by moving the second electric push rod, the third electric telescopic plate and the movable plate, it can be adjusted according to the hole of different size, so as to limit the hole of different size. This prevents the connection part between the two holes from being too small due to the distance between the two holes being too close, and the heat of the laser head during cutting will cause deformation of the connection part, thereby affecting the size and shape of the hole cutting.

[0022] (2) The present invention uses a cold air pipe to cool the cold air inside the storage cavity to the hole that needs to be cut. The function of the first cooling block and the second cooling block is to cool the inner wall of the hole when the second electric telescopic plate, the limiting plate, the third electric telescopic plate and the movable plate are in contact with the inner wall of the hole, thereby improving the cutting effect and preventing the temperature from being too high during cutting, which could cause the connection part of the two holes to deform and break, affecting subsequent cutting.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0035] This invention provides a laser cutting and welding apparatus for mold processing, such as... Figures 1 to 5 As shown, it includes processing equipment 1, and the processing equipment 1 is equipped with a laser processing structure;

[0036] The laser processing structure includes a processing table 2, a mounting frame 3, a moving structure 4, a connecting seat 5, a laser head 6, a connecting plate 7, a first motor 8, a rotating rod 9, a mounting plate, a slider 10, a first electric telescopic plate 11, and a limiting structure. The mounting frame 3 is located inside the processing equipment 1. The top two sides of the mounting frame 3 are provided with the moving structure 4. A connecting seat 5 is provided on one side of the moving structure 4. The laser head 6 is fixedly installed on one side of the connecting seat 5. The processing table 2 is provided in the middle of the mounting frame 3 and at the bottom of the laser head 6. The connecting plate 7 is provided at the bottom of the moving structure 4 and at the top of one side of the processing table 2. The first motor 8 is fixedly installed at the bottom of the connecting plate 7. The output end of the first motor 8 is driven by the rotating rod 9. The mounting plate is rotatably connected to one side of the rotating rod 9. The slider 10 is threadedly connected to the middle of the rotating rod 9. The top of the slider 10 is slidably connected to the bottom of the connecting plate 7. The first electric telescopic plate 11 is fixedly installed on one side of the slider 10. A limiting structure is provided on one side of the first electric telescopic plate 11.

[0037] The raw material for the mold is placed inside the processing equipment 1 and fixed on the processing table 2. At this time, the first electric telescopic plate 11 is in a retracted state, and the limiting structure is located behind the laser head 6. The moving structure 4 causes the connecting seat 5 to move the laser head 6. After moving to the appropriate position, the laser head 6 cuts the mold. When it is necessary to cut a hole of the same size and close distance in the vertical direction of the first hole after the mold is cut, the first electric telescopic plate 11 extends, causing the limiting structure to move to the bottom of the laser head 6. The moving structure 4 moves, causing the connecting seat 5 to move the laser head 6 to the cutting position. At the same time, the first motor 8 drives the rotating rod. 9 rotates along the mounting plate, causing the slider 10 to drive the first electric telescopic plate 11 and the limiting structure to move simultaneously with the laser head 6. When the limiting structure moves to the top of the mold, the laser head 6 is then moved to the position where the first hole needs to be cut after cutting, so that the limiting structure can fit against the inner wall of the first hole, limiting the inner wall of one side of the first hole after cutting. Then, the laser head 6 cuts the one side of the first hole again through the processing equipment 1, thereby preventing the distance between the two holes from being too close during cutting, resulting in too little connection between the two holes. The heat from the laser head 6 during cutting causes deformation of the connection part, thus affecting the size and shape of the hole cutting.

[0038] like Figures 3 to 5 As shown, the top of the mounting plate is fixedly installed to the bottom of the connecting plate 7. One end of the first electric telescopic plate 11 is located at the bottom of the connecting seat 5 and extends to one side of the laser head 6. The laser head 6 is located at the top of the processing table 2 and is located in the middle of the limiting structure.

[0039] The mounting plate facilitates stability when the first motor 8 drives the rotating rod 9 to rotate, and allows the slider 10 to move the limiting structure simultaneously with the laser head 6 to limit the cutting hole of the laser head 6. When the laser head 6 moves to the top of the first connecting block 13 and the second moving block 21, the first electric telescopic plate 11 retracts, causing the limiting structure to move to the rear side of the laser head 6, so that the laser head 6 can continue to cut other shapes and parts of the mold, thereby improving the cutting effect of the laser head 6.

[0040] like Figures 4 to 6As shown, the limiting structure includes a first electric push rod 12, a first connecting block 13, a second connecting block 14, a second electric telescopic plate 15, a limiting plate 16, a movable plate 17, and a second electric push rod 18. The top of the first electric push rod 12 is fixedly installed to the bottom of the first electric telescopic plate 11. The laser head 6 is provided with first connecting blocks 13 on both the front and rear sides. The bottom of the first electric push rod 12 is fixedly installed to the first connecting block 13 on the rear side of the laser head 6. The bottom of the first connecting block 13 is fixedly installed with the second electric telescopic plate 15. The laser head 6 is provided with second connecting blocks 14 on both the left and right sides. The bottom of the second connecting block 14 is fixedly installed with the limiting plate 16. The bottom of the limiting plate 16 is provided with the movable plate 17. Two second electric push rods 18 are provided in the middle of the second connecting block 14. One end of the two second electric push rods 18 is fixedly installed to both sides of the first connecting block 13.

[0041] The first electric push rod 12 pushes the first connecting block 13, the second connecting block 14, the second electric telescopic plate 15, the limiting plate 16, the movable plate 17, and the second electric push rod 18 to move to the top of the mold. When cutting the third hole, the second electric telescopic plate 15, the limiting plate 16, and the movable plate 17 can respectively fit against the inner walls of the first and second holes, limiting their inner walls and improving the stability when cutting the third hole. The second electric push rod 18 drives the extension of the first connecting block 13 and the second electric telescopic plate 15, which can be adjusted according to the hole size, improving the cutting effect, preventing hole deformation during cutting, and facilitating use.

[0042] like Figures 7 to 9 As shown, a movable groove is provided inside the limiting plate 16 near the second connecting block 14, and an adjustment structure is provided inside the movable groove;

[0043] The adjustment structure includes a second motor 19, a threaded rod 20, a moving block 21, a push rod 22, a movable block 23, and a third electric telescopic plate 24. The output end of the second motor 19 is connected to the threaded rod 20. One end of the threaded rod 20 is threadedly connected to the moving block 21. Both sides of the moving block 21 are slidably connected to the inner wall of the moving groove. Both sides of the moving block 21 are hinged to the push rod 22. One end of the push rod 22 is hinged to the movable block 23. The movable block 23 is movably connected to the inner wall of the moving groove. The third electric telescopic plate 24 is fixedly installed on one side of the movable block 23. The top of the second motor 19 is fixedly installed to the top inner wall of the moving groove. The bottom end of the threaded rod 20 is rotatably connected to the bottom inner wall of the moving groove. Both sides of the limiting plate 16 and the movable plate 17 have movable openings. The third electric telescopic plate 24 is located at the movable opening. The push rod 22, the movable block 23, and the third electric telescopic plate 24 are symmetrically arranged around the center of the moving groove.

[0044] When the size of the limiting plate 16 needs to be adjusted, the second motor 19 is started to drive the threaded rod 20 to rotate along the inner wall of the bottom of the moving groove, so that the moving block 21 moves downward along the inner wall of the moving groove from the threaded rod 20, and the push rod 22 deflects to push the movable block 23 to move along the inner wall of the moving groove, so that the movable block 23 drives the third electric telescopic plate 24 to move from the movable opening to the outside of the limiting plate 16 and the movable plate 17, adjusting the length of the limiting plate 16 and the movable plate 17 to adapt to holes of different sizes, making it convenient to cut holes of different sizes.

[0045] like Figures 7 to 9 As shown, the telescopic end of the third electric telescopic plate 24 and the inner walls of the movable openings on both sides of the movable plate 17 are provided with first fixing grooves. A first telescopic rod 25 is fixedly installed inside the first fixing groove. The third electric telescopic plate 24 is connected to the movable plate 17 through the first telescopic rod 25. A second fixing groove is provided at the bottom of the threaded rod 20. A second telescopic rod 26 is fixedly installed inside the second fixing groove. One end of the second telescopic rod 26 passes through the movable groove and is fixedly installed at the top of the movable plate 17.

[0046] When the third electric telescopic plate 24 moves from the movable opening to the outside of the limiting plate 16 and the movable plate 17, the first telescopic rod 25 extends. The first telescopic rod 25 facilitates the connection between the third electric telescopic plate 24 and the movable plate 17, thereby increasing the length of the movable plate 17 so that its length can be adjusted simultaneously with that of the limiting plate 16. The second telescopic rod 26 facilitates the connection between the limiting plate 16 and the movable plate 17. When the third electric telescopic plate 24 extends and moves downward, the first telescopic rod 25 drives the movable plate 17 to move downward, causing the second telescopic rod 26 to extend, so that the movable plate 17 remains stable when moving downward. When the third electric telescopic plate 24 and the movable plate 17 are extended, they can fit against the bottom inner wall of the cut hole, so that one side of the third electric telescopic plate 24, the limiting plate 16 and the movable plate 17 fits against the inner wall of the cut hole, which helps to improve the stability during cutting.

[0047] like Figure 10 As shown, a groove is provided at the bottom of the telescopic end of the second electric telescopic plate 15, and a fixing plate 27 is fixedly installed on the inner wall of the groove. A storage cavity 28 is provided at the top of the fixing plate 27 and inside the telescopic end of the second electric telescopic plate 15. Cold air is provided inside the storage cavity 28. A cold air pipe 29 is provided at the bottom of the fixing plate 27, and a control valve is provided at the top of the cold air pipe 29.

[0048] The control valve allows the cold air inside the storage chamber 28 to be delivered downwards through the cold air pipe 29. The action of the moving structure 4, the first motor 8, the rotating rod 9, and the slider 10 causes the second electric telescopic plate 15 to move back and forth. The action of the first electric push rod 12 and the first connecting block 13 causes the cold air pipe 29 at the bottom of the second electric telescopic plate 15 to move back and forth, cooling the first hole after cutting. This facilitates the cutting of another hole of the same size at a close distance in the vertical direction of the first hole after cutting. It can prevent the connection part from easily deforming due to excessive temperature when cutting a hole at a close distance, and further improve the stability of cutting.

[0049] like Figure 8 , Figure 10 As shown, the cooling pipes 29 are arranged in a linear array at the bottom of the fixed plate 27. The first cooling block 30 is fixedly installed on the outer side of the second electric telescopic plate 15, the outer side of the limiting plate 16 and the outer side of the movable plate 17. The second cooling block 31 is fixedly installed on the outer side of the third electric telescopic plate 24.

[0050] The linear array of cooling pipes 29 facilitates improved cooling. The first cooling block 30 cools the inner wall of the hole by making the second electric telescopic plate 15, the limiting plate 16, and the movable plate 17 fit together. The second cooling block 31 allows the third electric telescopic plate 24 to continue cooling the inside of the hole even after increasing the length of the limiting plate 16 and the movable plate 17, preventing any impact on dimensions and accuracy, thereby further improving the accuracy of cutting other holes.

[0051] The present invention also provides a process for using the above-described laser cutting and welding apparatus for mold processing, comprising the following steps:

[0052] Step 1: Place the raw material of the mold into the processing equipment 1 and fix it on the processing table 2. The connecting seat 5 drives the laser head 6 to move through the moving structure 4. At the same time, the rotating rod 9 is driven by the first motor 8 to rotate along the mounting plate, so that the slider 10 drives the first electric telescopic plate 11 and the limiting structure to move together with the laser head 6. After moving to the appropriate position, the mold is cut by the laser head 6.

[0053] Step Two: When it is necessary to cut a hole of the same size and close proximity to the first hole after the mold is cut, firstly, the cold air inside the storage chamber 28 is delivered downwards through the cold air pipe 29 via the control valve. Through the action of the moving structure 4, the first motor 8, the rotating rod 9, and the slider 10, the second electric telescopic plate 15 moves back and forth, causing the first electric push rod 12 to drive the first connecting block 13 and the second electric telescopic plate 15 to move, thus cooling the first hole after cutting. Then, the laser head 6 is moved to one side of the first hole after cutting, so that the limiting plate 16 and the movable plate 17 on the rear side of the laser head 6 are located at the top of the inner wall of one side of the first hole. The second motor 19 inside the limiting plate 16 on the rear side of the laser head 6 is activated, driving the threaded rod 20 to rotate along the inner wall of the moving groove, thus... The movable block 21 moves downward along the inner wall of the movable groove, the push rod 22 deflects and pushes the movable block 23 to drive the third electric telescopic plate 24 to move from the movable opening to the outside of the limiting plate 16, thereby adjusting according to the size of the hole. Then, through the action of the second electric push rod 18, the second connecting block 14, the limiting plate 16 and the movable block 23 move downward simultaneously. By activating the extension of the third electric telescopic plate 24, the second telescopic rod 26 extends, thereby causing the movable plate 17 to move downward and fit against the bottom inner wall of the first hole, so that one side of the limiting plate 16 and the movable plate 17 fits against the inner wall of the first hole. Through the first cooling block 30 and the second cooling block 31, the temperature is reduced within a certain time. Then, the laser head 6 is activated through the processing equipment 1 to cut one side of the first hole again.

[0054] Step 3: After the cutting is completed, the third electric telescopic plate 24 drives the movable plate 17 to move to its original position, and the second electric push rod 18 drives the limiting plate 16 and the movable plate 17 to move to their original positions. When it is necessary to cut a third hole of the same size and close distance in the horizontal direction of the first hole, when the laser head 6 moves to the horizontal side of the first hole, after adjusting to the appropriate position, the second electric telescopic plate 15 on the right side of the laser head 6 is opposite to the top of the left inner wall of the first hole. Then, by starting the second electric telescopic plate 15 to move downward, its bottom is attached to the bottom inner wall of the first hole. At the same time, one side of the second electric telescopic plate 15 is attached to the left inner wall of the first hole for limitation. The first cooling block 30 is used to cool down the hole, and then the laser head 6 cuts.

[0055] Step 4: When it is necessary to cut the left side of the second hole and the vertical direction of the third hole again, move the third electric telescopic plate 24 upward to its original position, move the laser head 6 to the position to be cut, so that the third electric telescopic plate 24 and the movable plate 17 are moved to the upper part of the second hole and face its inner wall. Activate the second electric push rod 18 so that the first connecting block 13 on the right side and the second electric telescopic plate 15 are moved to the inner wall of the left side of the second hole and face it. At the same time, activate the third electric telescopic plate 24 and the second electric telescopic plate 15 so that the second telescopic rod 26 is extended, so that the bottom of the movable block 23 is attached to the inner wall of the bottom of the second hole and one side of it is attached to the inner wall of the upper part of the second hole. The bottom of the second electric telescopic plate 15 is attached to the inner wall of the bottom of the second hole and to its left inner wall. After cooling by the first cooling block 30 and the second cooling block 31, the laser head 6 is then used for cutting.

[0056] Step 5: After cutting, conduct a comprehensive inspection of the cutting quality of the laptop mold parts, deburr and clean them, thoroughly clean the mold to be welded, and then weld them using the welding device.

[0057] Working principle: The raw material for the mold is placed inside the processing equipment 1 and fixed on the processing table 2. The moving structure 4 causes the connecting seat 5 to move the laser head 6. At the same time, the first motor 8 drives the rotating rod 9 to rotate along the mounting plate, causing the slider 10 to drive the first electric telescopic plate 11 and the limiting structure to move simultaneously with the laser head 6. After moving to the appropriate position, the laser head 6 cuts the mold. When it is necessary to cut a hole of the same size and close distance in the vertical direction of the first hole after the mold is cut, the control valve first causes the cold air inside the storage chamber 28 to be delivered downward through the cold air pipe 29. Through the action of the moving structure 4, the first motor 8, the rotating rod 9 and the slider 10, the second electric telescopic plate 15 moves back and forth, causing the first electric push rod 12 to drive the first connecting block 13 and the second electric telescopic plate 15 to move, cooling the first hole after cutting. Then the laser head 6 is moved to one side of the first hole after cutting, so that the limiting structure behind the laser head 6... Plate 16 and movable plate 17 are located on the top of the inner wall of one side of the first hole. The second motor 19 inside the limiting plate 16 behind the laser head 6 drives the threaded rod 20 to rotate along the inner wall of the moving groove, so that the moving block 21 moves downward along the inner wall of the moving groove. The push rod 22 deflects and pushes the movable block 23 to drive the third electric telescopic plate 24 to move from the movable opening to the outside of the limiting plate 16, thereby adjusting according to the size of the hole. Then, the second electric push rod 18 drives the second connecting block 14, the limiting plate 16 and the movable block 23 to move downward at the same time. By activating the third electric telescopic plate 24 to extend, the second telescopic rod 26 extends, so that the movable plate 17 moves downward and fits against the bottom inner wall of the first hole, so that one side of the limiting plate 16 and the movable plate 17 fits against the inner wall of the first hole. The first cooling block 30 and the second cooling block 31 cool the area for a limited time. Then, the laser head 6 is activated again to cut one side of the first hole through the processing equipment 1.

[0058] After cutting, the third electric telescopic plate 24 moves the movable plate 17 to its original position, and the second electric push rod 18 moves the limiting plate 16 and the movable plate 17 to their original positions. When it is necessary to cut a third hole of the same size and close distance in the horizontal direction of the first hole, when the laser head 6 moves to the horizontal side of the first hole, after adjusting to the appropriate position, the second electric telescopic plate 15 on the right side of the laser head 6 is aligned with the top of the left inner wall of the first hole. Then, by activating the second electric telescopic plate 15, it moves downward so that its bottom is in contact with the bottom inner wall of the first hole. At the same time, one side of the second electric telescopic plate 15 is in contact with the left inner wall of the first hole for limitation. The first cooling block 30 cools the area, and then the laser head 6 cuts. When it is necessary to cut the left side of the second hole and the third hole vertically again... During cutting, the third electric telescopic plate 24 is moved upward to its original position, and the laser head 6 is moved to the position to be cut, so that the third electric telescopic plate 24 and the movable plate 17 are moved to the upper part of the second hole and opposite to its inner wall. The second electric push rod 18 is activated so that the first connecting block 13 on the right side and the second electric telescopic plate 15 are moved to the left inner wall of the second hole and opposite to it. At the same time, the third electric telescopic plate 24 and the second electric telescopic plate 15 are activated so that the second telescopic rod 26 is extended, so that the bottom of the movable block 23 is attached to the bottom inner wall of the second hole and one side of it is attached to the upper inner wall of the second hole. The bottom of the second electric telescopic plate 15 is attached to the bottom inner wall of the second hole and its left inner wall. After cooling by the first cooling block 30 and the second cooling block 31, the laser head 6 is then used for cutting.

[0059] After cutting, a comprehensive inspection of the cutting quality of the laptop mold parts is conducted, including deburring and cleaning. The mold to be welded is thoroughly cleaned before welding.

A process using the laser cutting and welding apparatus for mold processing as described in claims 1 to 6, characterized in that, Includes the following steps: Step 1: Place the raw material of the mold into the processing equipment (1) and fix it on the processing table (2). The connecting seat (5) is moved by the moving structure (4) to drive the laser head (6) to move. At the same time, the rotating rod (9) is driven by the first motor (8) to rotate along the mounting plate, so that the slider (10) drives the first electric telescopic plate (11) and the limiting structure to move simultaneously with the laser head (6). After moving to the appropriate position, the mold is cut by the laser head (6). Step 2: When it is necessary to cut a hole of the same size and close proximity to the first hole after the mold is cut, firstly, the cold air inside the storage chamber (28) is transported downwards by the cold air pipe (29) through the control valve. Through the action of the moving structure (4), the first motor (8), the rotating rod (9), and the slider (10), the second electric telescopic plate (15) moves back and forth, causing the first electric push rod (12) to drive the first connecting block (13) and the second electric telescopic plate (15) to move, cooling the first hole after cutting. Then, the laser head (6) is moved to one side of the first hole after cutting, so that the limiting plate (16) and the movable plate (17) on the back side of the laser head (6) are located at the top of the inner wall of one side of the first hole. The second motor (19) inside the limiting plate (16) on the back side of the laser head (6) is started to drive the threaded rod (20) to rotate along the inner wall of the moving groove, so that... The moving block (21) moves downward along the inner wall of the moving groove. The push rod (22) deflects and pushes the movable block (23) to drive the third electric telescopic plate (24) to move from the movable opening to the outside of the limiting plate (16), thereby adjusting according to the size of the hole. Then, through the action of the second electric push rod (18), the second connecting block (14), the limiting plate (16) and the movable block (23) move downward simultaneously. By starting the third electric telescopic plate (24) to extend, the second telescopic rod (26) extends, thereby causing the movable plate (17) to move downward and fit against the bottom inner wall of the first hole, so that one side of the limiting plate (16) and the movable plate (17) fits against the inner wall of the first hole. Through the first cooling block (30) and the second cooling block (31), the temperature is reduced during the time limit. Then, the laser head (6) is started to cut one side of the first hole again through the processing equipment (1).

When it is necessary to cut a third hole of the same size and close distance in the horizontal direction of the first hole, when the laser head (6) moves to the horizontal side of the first hole, after adjusting to the appropriate position, the second electric telescopic plate (15) on the right side of the laser head (6) is opposite to the top of the left inner wall of the first hole. Then, by starting the second electric telescopic plate (15) to move downward, its bottom is attached to the bottom inner wall of the first hole. At the same time, one side of the second electric telescopic plate (15) is attached to the left inner wall of the first hole for limitation. The first cooling block (30) is used to cool down, and then the laser head (6) cuts. Step 4: When it is necessary to cut the left side of the second hole and the vertical direction of the third hole again, move the third electric telescopic plate (24) upward to its original position, move the laser head (6) to the position to be cut, so that the third electric telescopic plate (24) and the movable plate (17) are moved above the second hole and are opposite to its inner wall. Start the second electric push rod (18) so that the first connecting block (13) on the right side and the second electric telescopic plate (15) are moved to the inner wall of the left side of the second hole and are opposite to it. At the same time, start the third electric telescopic plate (24) and the second electric telescopic plate (15) so that the second telescopic rod (26) is extended, so that the bottom of the movable block (23) is attached to the inner wall of the bottom of the second hole and one side of it is attached to the inner wall of the top of the second hole. The bottom of the second electric telescopic plate (15) is attached to the inner wall of the bottom of the second hole and to its left inner wall.
