Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, and in particular to a cooling mechanism of an aviation titanium alloy laser cutting machine. Background Art

[0002] Titanium alloy has the properties of high specific strength, low density, high temperature resistance, corrosion resistance and non-magneticity, making it one of the most commonly used metals in the aerospace field. In the production process of aviation titanium alloy materials, laser cutting machines are needed to cut titanium alloy materials. Laser cutting is a processing method that uses a high-energy laser beam to cut materials. Laser cutting technology usually uses carbon dioxide laser or fiber laser. After collimation and focusing, the laser beam has high energy density and can quickly heat the material to a high temperature and evaporate it, thereby achieving cutting. During the operation of the laser head, the laser generated will cause the laser head and related components to heat up, so a cooling system is required to maintain the appropriate temperature to ensure the performance and life of the equipment.

[0003] A laser cutting machine with a cooling mechanism is disclosed in the prior art with publication number CN116586760A. In the laser cutting machine with a cooling mechanism, a steering plate is used to control a carrying plate to be in a horizontal and rotating state, and the carrying plate is used to control waste liquid on the guide surface of the workpiece to drip to different positions on the filter plate, thereby reducing the possibility of clogging of the filter plate and facilitating subsequent filtering of the waste liquid. At the same time, the movement of the carrying plate is used to control the movement of the filter plate and the pressure plate, so that the pressure plate compresses the waste liquid filtered and recovered in the liquid tank, and the waste liquid is secondary sprayed to the bottom cutting opening of the workpiece, thereby improving the cooling efficiency of the cutting opening of the workpiece.

[0004] Although it can reduce the phenomenon of filter plate clogging, there are still some defects in actual use. Since the laser cutting machine cools the workpiece and the laser cutting head by spraying water, there is no blocking component above the workpiece, and most of the coolant sprayed on the workpiece will flow on the surface of the workpiece. Therefore, when processing some longer titanium alloy workpieces, the coolant sprayed on the surface will flow outward along the surface of the workpiece. If a larger cutting table is equipped, it will be wasteful, and if it is not blocked, it will also cause waste of coolant.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-9 The cooling mechanism of an aviation titanium alloy laser cutting machine shown in the figure comprises a cutting table 1 and a laser cutting gun 2, the cutting table 1 is provided with a multi-axis driving mechanism 3 for driving the multi-axis movement of the laser cutting gun 2, the laser cutting gun 2 is provided with a water spray cooling mechanism 4, the side wall of the laser cutting gun 2 is bolted with a side plate 5, a circular frame 6 is provided below the side plate 5, an annular scraper 7 is provided below the circular frame 6, a slag cleaning mechanism is provided inside the annular scraper 7, an adjusting mechanism for adjusting the inclination angle of the circular frame 6 is provided between the side plate 5 and the circular frame 6, and the center position of the circular frame 6 is aligned with the center position of the laser cutting gun 2;

[0032] When laser cutting the titanium alloy material, first place the titanium alloy material on the cutting table 1, then control the multi-axis drive mechanism 3 to move the laser cutting gun 2 to the top of the workpiece surface where cutting is required, and at the same time, place the annular scraper 7 close to the upper surface of the workpiece, then start the hole laser cutting gun 2 to laser cut the titanium alloy material, and at the same time control the water spray cooling mechanism 4 to spray coolant to cool the laser cutting gun 2 and the cutting position of the titanium alloy material. At the same time, the sprayed coolant falls on the surface of the workpiece and is concentrated in the circular frame 6 under the obstruction of the annular scraper 7, which can effectively prevent the coolant from flowing along the surface of the workpiece and reduce waste, and the blocked coolant will fall along the cutting gap to the bottom of the cutting table 1 and enter the circulating cooling system in the water spray cooling mechanism 4 for circulating cooling.

[0033] The cleaning mechanism includes a cleaning motor 8, a gear ring 9 is rotatably connected to the top of the circular frame 6, the cleaning motor 8 is fixedly connected to the top of the circular frame 6, the output end of the cleaning motor 8 passes through the top of the circular frame 6 and is fixedly connected to a gear 10 meshing with the gear ring 9, the bottom of the gear ring 9 is fixedly connected to a fixed cylinder 11, a lower scraper 12 is slidably connected to the inside of the fixed cylinder 11, and a limit plate 13 is fixedly connected to the top of the lower scraper 12, a pair of upper springs 14 are fixedly connected between the top of the limit plate 13 and the top of the fixed cylinder 11, a collecting block 15 is fixedly connected to the inside of the annular scraper 7, and inclined grooves 16 are provided on both sides of the collecting block 15, and a sunken groove 17 is provided on the top of the collecting block 15;

[0034] The cleaning motor 8 is controlled to start the gear 10 to rotate, which in turn drives the meshing gear ring 9 to rotate, and then drives the fixed cylinder 11 and the lower scraper 12 at the bottom to rotate, so as to clean the slag on the surface of the workpiece after cutting. Then the cleaned slag follows the lower scraper 12 to move to the collecting block 15. Under the extrusion of the inclined groove 16, the lower scraper 12 will slide upward along the inclined groove 16 into the fixed cylinder 11, and at the same time compress the upper spring 14, and drive the slag to move to the collecting block 15. Then the lower scraper 12 moves to the top of the groove 17, and the slag pushed by the lower scraper 12 falls into the groove 17. Then the lower scraper 12 moves away through another inclined groove 16 and gradually resets under the thrust of the upper spring 14. At the same time, the slag enters the collecting box 20 through the discharge port 24 for unified collection and treatment. This is repeated, and the slag on the surface of the workpiece during the cutting process can be cleaned and collected to avoid excessive slag mixing with the coolant and reduce the possibility of clogging of the filter screen on the water spray cooling mechanism 4.

[0035] In order to prevent the scraped coolant from being discharged into the collection box 20, a plurality of drainage holes 18 are opened through the top of the inclined groove 16. Through the setting of the drainage holes 18, the coolant scraped by the lower scraper 12 can be discharged to ensure that only the scraping residue enters the groove 17. The side wall of the lower scraper 12 is inclined to facilitate the inclined groove 16 to better squeeze the lower scraper 12 to slide upward, and the bottom end of the groove 17 is inclined toward the outside to facilitate the fallen slag to be discharged into the collection box 20, thereby improving the practical performance of the device. In addition, the width of the groove 17 is smaller than the width of the lower scraper 12 to prevent the lower scraper 12 from falling into the groove 17, thereby ensuring the normal operation of the device.

[0036] In order to facilitate the removal of the collected slag for centralized treatment, a pair of upper L-shaped plates 19 are fixedly connected to the outer side of the annular scraper 7 and located next to the collecting block 15, a collecting box 20 is provided between the upper L-shaped plates 19, a blocking plate 21 is provided at the top of the collecting box 20, plug blocks 22 are fixedly connected to both sides of the collecting box 20, and a slot 23 adapted to the upper L-shaped plate 19 is provided at the top of the plug block 22, and a discharge port 24 is provided at the side wall of the collecting box 20 and the annular scraper 7 and at a position corresponding to the groove 17, and the upper L-shaped plate 19 is plugged into the inner side of the slot 23;

[0037] When the equipment is finished running and the slag collected in the collection box 20 needs to be cleaned, the collection box 20 can be pushed upward to drive the insert block 22 to slide upward, and then the upper L-shaped plate 19 can be slid out of the slot 23, and then the blocking plate 21 can be opened to pour out the slag collected in the collection box 20, and then the blocking plate 21 can be covered, and finally the collection box 20 can be inserted back, and the upper L-shaped plate 19 can be tightly inserted into the slot 23.

[0038] In order to be able to adjust the inclination angle of the circular frame 6 so that the shielding structure can be used on a workpiece with an inclined surface, the adjustment mechanism includes an upper bolt 25 and a lower bolt 26. The side wall of the side plate 5 is rotatably connected to the lower L-shaped plate 28, and the upper bolt 25 is threadedly connected to the side wall of the lower L-shaped plate 28, and the side wall of the upper bolt 25 is butted against the side wall of the side plate 5. An adjustment groove 27 is penetrated through the top of the lower L-shaped plate 28, and a rotating block 29 is fixedly connected to the top of the circular frame 6 and at a position corresponding to the adjusting groove 27. Both ends of the rotating block 29 are rotatably connected to the inner side of the adjusting groove 27, and the lower bolt 26 is threadedly connected to the side wall of the lower L-shaped plate 28, and the side wall of the lower bolt 26 is butted against the side wall of the rotating block 29.

[0039] When the surface of the workpiece being cut is inclined, the corresponding position can be adjusted according to the inclination direction of the workpiece. When the longitudinal inclination angle of the annular scraper 7 needs to be adjusted, the upper bolt 25 can be rotated. Due to the threaded connection between the upper bolt 25 and the lower L-shaped plate 28, the upper bolt 25 can be spirally moved outward, thereby releasing the extrusion of the side wall of the side plate 5 and releasing the restriction on the rotation position of the lower L-shaped plate 28. The lower L-shaped plate 28 can be rotated to rotate on the side wall of the side plate 5, thereby realizing the adjustment of the longitudinal inclination angle of the circular frame 6 and the annular scraper 7, so that the bottom of the annular scraper 7 can be fitted with the top of the workpiece with an inclined surface, thereby ensuring the blocking effect of the sprayed coolant, reducing waste, and improving the application range of the device. After the adjustment is completed, the upper bolt 25 is rotated in the opposite direction to make the side wall of the upper bolt 25 abut against the side wall of the side plate 5.

[0040] When it is necessary to adjust the lateral inclination angle of the annular scraper 7, the lower bolt 26 can be rotated. Due to the threaded connection between the lower bolt 26 and the lower L-shaped plate 28, the lower bolt 26 will be spirally moved outward, thereby releasing the abutment between the lower bolt 26 and the side wall of the rotating block 29, and releasing the rotation restriction of the rotating block 29. Then, the circular frame 6 can be rotated to drive the rotating block 29 to rotate inside the adjustment groove 27, thereby changing the inclination angle of the annular scraper 7. It should be noted here that since the circular frame 6 is restricted by the bottom of the lower L-shaped plate 28, the circular frame 6 can only rotate downward. Therefore, when placing the workpiece, it can be placed according to the inclination direction of the workpiece surface to ensure the normal operation of the device. Then, after the adjustment is completed, the lower bolt 26 is rotated in the opposite direction so that the lower bolt 26 is abutted against the side wall of the rotating block 29.

[0041] In order to improve the accuracy of adjusting the inclination angle of the annular scraper 7, a pointer 30 is fixedly connected to the top of the lower L-shaped plate 28, an upper scale groove 31 is opened at the side wall of the side plate 5 and at a position corresponding to the pointer 30, a top block 32 is fixedly connected to the top of the lower L-shaped plate 28 and located at the side wall of the adjustment groove 27, and a lower scale groove 33 is opened on the side wall of the top block 32, and a rotation groove 39 is opened at the top of the round frame 6 and located below the lower bolt 26, through the rotation groove 39, it is convenient to rotate the lower bolt 26, and then quickly release the rotation restriction of the rotation block 29, so as to facilitate the adjustment of the lateral inclination angle of the annular scraper 7, thereby improving the convenience performance of the device;

[0042] While adjusting the lateral inclination angle of the annular scraper 7, the position of the top of the rotating block 29 on the lower scale groove 33 can be observed, and the lateral inclination angle of the annular scraper 7 can be accurately adjusted according to the inclination angle of the workpiece surface. When adjusting the longitudinal inclination angle of the annular scraper 7, the rotation of the lower L-shaped plate 28 will drive the pointer 30 to rotate at the same time, and then by observing the position of the pointer 30 on the upper scale groove 31, the longitudinal inclination angle of the annular scraper 7 can be accurately adjusted according to the inclination angle of the workpiece surface, thereby ensuring the accuracy of the adjustment and ensuring the blocking effect of the coolant on the inclined surface workpiece.

[0043] In order to adjust the position of the annular scraper 7 as the slope of the workpiece surface increases, a telescopic groove 34 adapted to the annular scraper 7 is provided at the bottom of the circular frame 6, and the annular scraper 7 is slidably connected to the inner side of the telescopic groove 34, and a plurality of lower springs 35 are fixedly connected between the top of the telescopic groove 34 and the annular scraper 7;

[0044] When the laser cutting gun 2 cuts a workpiece with an inclined surface, the circular frame 6 is adjusted to the same inclination angle as the workpiece surface. At this time, the bottom of the annular scraper 7 fits against the workpiece surface. Then, during the cutting process, as the laser cutting gun 2 gradually moves, the annular scraper 7 will gradually move from the lowest inclined position on the workpiece surface to the highest position, thereby gradually squeezing the annular scraper 7 upward to slide on the inside of the telescopic groove 34, while compressing the lower spring 35. At the same time, the lower scraper 12 also slides into the fixed cylinder 11 under compression to compress the upper spring 14, thereby ensuring that the annular scraper 7 can be used for workpieces with inclined surfaces and will not hinder the normal operation of the laser cutting gun 2.

[0045] In order to improve the stability of the device during operation, a pair of guide rods 36 are fixedly connected to the top of the annular scraper 7, and the top of the guide rods 36 passes through the top of the circular frame 6. The top of the guide rods 36 is fixedly connected to a positioning plate 37. Through the setting of the guide rods 36, the rotation position of the annular scraper 7 can be limited, and the up and down sliding position of the annular scraper 7 can be limited by the positioning plates 37 to prevent the annular scraper 7 from slipping out of the telescopic groove 34, thereby improving the stability of the device during operation.

[0046] In order to avoid affecting the normal operation of the adjustment mechanism, a slide groove 38 is provided at the bottom of the circular frame 6 and at a position corresponding to the collecting block 15. The setting of the slide groove 38 can prevent the annular scraper 7 from sliding upward, thereby causing the collecting block 15 and the collecting box 20 to slide upward and being obstructed, thereby affecting the normal operation of the device.

[0047] The basic principles, main features and advantages of the present invention are shown and described above.

[0048] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
