Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and more specifically, to a laser cutting device for an oil filter mounting bracket. Background Technology

[0002] Laser cutting equipment is an automated device that focuses a high-energy laser beam onto the surface of a material to achieve non-contact precision cutting through melting, vaporization, or oxidation reactions. It is a core tool in modern industrial manufacturing.

[0003] Existing laser cutting equipment generally adopts a single-hole cutting mode when processing holes in filter element supports. During operation, the filter element support is first fixed to the cutting worktable. After the laser cutting head completes the cutting of one hole, the CNC system drives the cutting head or worktable to move to the next hole coordinate, and then the subsequent holes are processed one by one. The number of holes to be cut in the filter element support is large, and the laser cutting head needs to start and stop frequently and move and position repeatedly. Multiple idle strokes and repeated positioning processes consume a lot of processing time, making it impossible to achieve multi-hole synchronous one-time cutting. On the other hand, when processing multiple filter element supports in the same batch continuously, it is necessary to repeatedly perform operations such as loading, fixing, hole-by-hole cutting, and moving. The process is cumbersome and lacks continuity, which affects the processing efficiency of the laser cutting equipment and cannot meet the needs of large-scale and high-efficiency production. Summary of the Invention

[0004] The purpose of this invention is to provide a laser drilling device for oil filter mounting brackets, in order to solve the problems mentioned in the background art above:

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A turntable is fixedly installed on the bottom surface of the rotating shaft. The surface of the turntable has multiple sliding grooves. A matching sliding plate is slidably connected inside any of the sliding grooves. A missing gear is fixedly installed at one end of any of the sliding plates. A rotating shaft is rotatably connected to the bottom surface of any of the sliding plates. A gear wheel that meshes with the missing gear is fixedly installed on the surface of any of the rotating shafts. A laser cutter for cutting holes in the filter element bracket is provided below any of the rotating shafts.

[0007] Preferably, the number of sliding columns and arc plates are the same, the number of slots and sliding grooves are the same and their positions correspond, and a spring is elastically connected between the slider and the slot. One end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner wall of the slot.

[0008] Preferably, a second spring is elastically connected between the slide plate and the slide groove, one end of the second spring is fixedly connected to the other end of the slide plate, and the other end of the second spring is fixedly connected to the inner wall of the slide groove.

[0009] Preferably, each of the sliding columns has two limiting plates fixedly installed on its surface. The arc-shaped plate is located between the two limiting plates, and the distance between the two limiting plates is adapted to the thickness of the arc-shaped plate. Fixed columns are fixedly installed at the four corners of the surface of the fixed plate. A rotating seat is fixedly installed on the surface of the four fixed columns. The bottom surface of the gear ring has an annular groove that matches the rotating seat, and the rotating seat is rotatably connected to the annular groove.

[0010] Preferably, a connecting plate is fixedly installed on the side surface of the fixing plate, a helical gear that meshes with the gear ring is rotatably connected above the connecting plate, a micro motor is fixedly installed on the bottom surface of the connecting plate, and the output end of the micro motor is fixedly connected to the helical gear.

[0011] Preferably, a micro motor is fixedly installed in the middle of the surface of the lifting frame, the output end of the micro motor is fixedly connected to the rotating shaft, and a fixing frame is fixedly installed on the surface of the lifting frame.

[0012] Preferably, a telescopic device is fixedly installed on the inner top surface of the laser cutting equipment, and the telescopic end of the telescopic device is fixedly connected to the fixed frame. A processing table for placing filter element brackets is fixedly installed on the inner bottom surface of the laser cutting equipment.

[0013] Preferably, a crossbeam is fixedly installed on the bottom surface of any one of the rotating shafts, and a movable groove is opened on the bottom surface of any one of the crossbeams. A matching movable block is slidably connected inside the movable groove, and the laser cutter is installed on the bottom surface of the movable block.

[0014] Preferably, a ruler is fixedly installed on the surface of any one of the crossbars, and a rotating groove is formed on the surface of the movable block.

[0015] Preferably, the surface of the crossbar is threaded with a through-type threaded rod, and the inside of the rotating groove is rotatably connected with a matching circular rotating plate. The circular rotating plate is fixedly connected to one end surface of the threaded rod, and a knob is fixedly installed on the other end surface of the threaded rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1) When using the laser cutting device for the oil filter mounting bracket, the gear ring rotates counterclockwise, causing multiple arc-shaped plates to rotate and press against multiple sliding columns, based on the size of the filter element bracket and the location of the required cut holes. This causes the slider to move, driving the rotating shaft and geared wheels. The geared wheels then drive the missing gears, which in turn drive the sliding plate into the groove. The movement of multiple rotating shafts centers multiple laser cutters in their position, laser-cutting the filter element bracket surface. Simultaneously, the turntable rotates, causing multiple sliding plates to rotate. The rotating plates then drive the missing gears to rotate counterclockwise, which in turn drives multiple geared wheels to rotate. With the rotation of multiple rotating shafts, multiple laser cutters make a single circular cut on the surface of the filter element holder. Compared with traditional laser cutting devices, this laser cutting equipment can adjust the laser cutters according to the different specifications and cut positions of the filter element holder. Moreover, it can make a single circular cut on multiple cut positions of the filter element holder without having to cut subsequent holes one by one, which improves the cutting efficiency of the laser cutting equipment for filter element holders. At the same time, for processing a single filter element holder of the same specification, it is not necessary to cut the cut positions of the filter element holder one by one, which meets the needs of large-scale and high-efficiency production.

[0018] 2) When using the laser cutting device for the oil filter mounting bracket, to cut holes of different sizes for the filter element bracket, the knob is turned according to the desired hole size, causing the threaded rod to rotate inwards. The rotating threaded rod causes the movable block to move inside the movable groove, thereby adjusting the laser cutter along with the movable block. During the adjustment of the laser cutter, the scale is observed in real time. When the distance between the laser cutter and the rotating shaft is the same as the radius of the hole to be cut, the knob is stopped. The rotation of multiple rotating shafts causes multiple working laser cutters to perform a one-time annular cut on the surface of the filter element bracket, increasing the versatility and practicality of the laser cutting equipment.

[0031] Example 1: Please refer to Figure 1 - Figure 11A laser-cutting device for an oil filter mounting bracket includes a laser cutting device 1 and a filter element bracket 2 to be cut placed inside it. The laser cutting device 1 performs laser-cutting on the filter element bracket 2. The filter element bracket 2 is a conventional filter element bracket in the prior art. The laser cutting device 1 has a vertically movable lifting frame 3 inside. A fixing plate 4 is fixedly installed on the bottom surface of the lifting frame 3. The surface of the fixing plate 4 has multiple through slots 5. A matching slider 6 is slidably connected inside any slot 5. The slider 6 matches the slot 5 to prevent the slider 6 from shaking during movement. A sliding column 7 is fixedly connected to the surface of any slider 6. The cylindrical design of the sliding column 7 allows the arc plate 9 to more smoothly compress the sliding column 7. Multiple sliding columns 7 are collectively equipped with a rotatable gear ring 8. The rotation of the gear ring 8 provides power for the operation of the arc-shaped plate 9. Multiple arc-shaped plates 9 for pressing the sliding columns 7 are fixedly installed on the inner wall of the gear ring 8. A through-type rotating shaft 10 is rotatably connected to the middle surface of the fixed plate 4. A turntable 11 is fixedly installed on the bottom surface of the rotating shaft 10. Multiple sliding grooves 12 are opened on the surface of the turntable 11. A matching sliding plate 13 is slidably connected inside any sliding groove 12. A missing gear 14 is fixedly installed at one end of any sliding plate 13. The number of teeth of the missing gear 14 and the toothed wheel 16 can be set according to actual production needs. When the missing gear 14 rotates a certain angle, the toothed wheel 16 can meet the requirement of rotating one revolution. A rotating shaft is rotatably connected to the bottom surface of any sliding block 6. 15. Each rotating shaft 15 has a fixedly mounted gear 16 that meshes with the missing gear 14. Below each rotating shaft 15 is a laser cutter 17 for cutting holes in the filter element support 2. The laser cutter 17 is a conventional laser cutter in the prior art. Based on the size of the filter element support 2 and the required hole location, the gear ring 8 rotates counterclockwise, causing multiple arc-shaped plates 9 to rotate and press against multiple sliding pillars 7. This causes the slider 6 to move, moving the rotating shaft 15 and the gear 16. The gear 16 moves, moving the missing gear 14. The missing gear 14 moves the sliding plate 13 into the groove 12. The movement of the multiple rotating shafts 15 causes the multiple laser cutters 17 to move centrally, thus laser-cutting holes in the surface of the filter element support 2. At the same time, the turntable 11 rotates, causing multiple slide plates 13 to rotate. The rotation of slide plates 13 causes the missing gears 14 to rotate counterclockwise. The rotation of multiple missing gears 14 causes multiple geared wheels 16 to rotate. The rotation of geared wheels 16 causes the rotating shaft 15 to rotate. The rotation of multiple rotating shafts 15 causes multiple working laser cutters 17 to perform a one-time annular cut on the surface of the filter element support 2. Compared with traditional laser cutting devices, this laser cutting equipment 1 can adjust the laser cutters 17 according to the different specifications and cut hole positions of the filter element support 2. Moreover, it can perform a one-time annular cut on multiple cut hole positions of the filter element support 2 without having to complete the subsequent hole cuts one by one, thus improving the cutting efficiency of the laser cutting equipment 1 on the filter element support 2. At the same time, it can process a single filter element support 2 of the same specification.It eliminates the need for repeated cutting at each of the filter element holder's two cut holes, thus meeting the demands of large-scale, high-efficiency production.

[0032] The number of sliding columns 7 and arc plates 9 are the same, the number of slots 5 and sliding grooves 12 are the same and their positions correspond, and a spring 18 is elastically connected between the slider 6 and the slot 5. One end of the spring 18 is fixedly connected to the slider 6, and the other end of the spring 18 is fixedly connected to the inner wall of the slot 5. The spring 18 is used for the movement reset of the slider 6.

[0033] A second spring 20 is elastically connected between the slide plate 13 and the slide groove 12. The second spring 20 is used for the movement reset of the slide plate 13. One end of the second spring 20 is fixedly connected to the other end of the slide plate 13, and the other end of the second spring 20 is fixedly connected to the inner wall of the slide groove 12.

[0034] Two limiting plates 19 are fixedly installed on the surface of each sliding column 7. The design of the limiting plates 19 prevents the arc plate 9 from deviating when it rotates with the gear ring 8. The arc plate 9 is located between the two limiting plates 19, and the distance between the two limiting plates 19 is adapted to the thickness of the arc plate 9. Fixed columns 21 are fixedly installed at the four corners of the surface of the fixed plate 4. The rotating seat 22 is fixedly installed on the surface of the four fixed columns 21. The bottom surface of the gear ring 8 is provided with an annular groove 23 that matches the rotating seat 22. The rotating seat 22 is rotatably connected to the annular groove 23. Through the design of the rotating seat 22 and the annular groove 23 and the setting of the two limiting plates 19, the normal rotation of the gear ring 8 is ensured, and the rotational deviation of the gear ring 8 is prevented, thereby realizing the stable compression of the sliding column 7 by the arc plate 9.

[0035] A connecting plate 24 is fixedly installed on the side surface of the fixed plate 4. A helical gear 25 that meshes with the gear ring 8 is rotatably connected above the connecting plate 24. A micro motor 26 is fixedly installed on the bottom surface of the connecting plate 24. The micro motor 26 is a conventional forward and reverse micro motor 26 in the prior art. The output end of the micro motor 26 is fixedly connected to the helical gear 25.

[0036] A micro motor 27 is fixedly installed in the middle of the surface of the lifting frame 3. The micro motor 27 is a conventional forward and reverse micro motor 27 in the prior art. The micro motor 27 can rotate in both directions, and the rotation speed and rotation angle can be controlled. The output end of the micro motor 27 is fixedly connected to the rotating shaft 10. A fixing frame 28 is fixedly installed on the surface of the lifting frame 3.

[0037] An extension device 29 is fixedly installed on the top surface inside the laser cutting equipment 1. The extension device 29 is a conventional electrically controlled push rod in the prior art. The extension device 29 can ensure the cutting distance between the laser cutter 17 and the filter element support 2, and improve the cutting quality of the filter element support 2 by the laser cutter 17. The extension end of the extension device 29 is fixedly connected to the fixed frame 28. A processing table 30 for placing the filter element support 2 is fixedly installed on the bottom surface inside the laser cutting equipment 1. The processing table 30 is a conventional processing table 30 in the prior art. The surface of the processing table 30 is equipped with existing clamping devices.

[0038] The steps of using this invention are as follows: When using the laser cutting device for the oil filter mounting bracket, to cut different batches of filter element brackets 2, firstly, according to the size of the plate surface of the filter element bracket 2 and the position of the required cutting hole, start the micro motor 26. The micro motor 26 rotates, causing the helical gear 25 to rotate, which in turn causes the gear ring 8 to rotate. At this time, the gear ring 8 rotates on the surface of the rotating base 22. The counterclockwise rotation of the gear ring 8 causes multiple arc plates 9 to rotate, pressing multiple sliding pillars 7. After being pressed, the multiple sliding pillars 7 move, causing the slider 6 to slide in the center of the slot 5, compressing the spring 18. The movement of the slider 6 causes the rotating shaft 15 and the gear wheel 16 to move (the gear wheel 16 meshes with the missing gear 14 and does not disengage). The movement of the gear wheel 16 causes the missing gear 14 to move. The movement of gear 14 causes the slide plate 13 to move into the slide groove 12, compressing the spring 20. Multiple rotating shafts 15 move, causing multiple laser cutters 17 to move centrally. When the axes of the multiple rotating shafts 15 align with the centers of the multiple cutting holes, the micro motor 26 stops working. Then, the filter element support 2 is placed on the surface of the processing table 30 and fixed. After the filter element support 2 is placed, its center position aligns with the axis of the rotating shaft 10. When laser cutting holes are made on the surface of the filter element support 2, the telescopic device 29 extends, causing the fixed frame 28 and the lifting frame 3 to descend. The descent of the lifting frame 3 causes the fixed plate 4 to descend, and the movement of the fixed plate 4 causes the multiple laser cutters 17 to move downwards. When the distance between the laser cutters 17 and the filter element support 2 is suitable for cutting... When cutting the distance, the telescopic device 29 stops working. Then, the micro motor 27 and the laser cutter 17 work simultaneously. The micro motor 27 slowly rotates, causing the rotating shaft 10 to rotate (the micro motor 27 can rotate in both directions, and the rotation speed and angle are controllable). The rotating shaft 10 rotates, causing the turntable 11 to rotate. The turntable 11 rotates, causing multiple sliding plates 13 to rotate. The sliding plates 13 rotate, causing the missing gear 14 to rotate counterclockwise. The multiple missing gears 14 rotate, causing multiple geared wheels 16 to rotate. The geared wheels 16 rotate, causing the rotating shaft 15 to rotate. The multiple rotating shafts 15 rotate, causing multiple working laser cutters 17 to perform a one-time annular cut on the surface of the filter element support 2. This scheme is based on the size of the filter element support 2 and the location of the required cut. The gear ring 8 rotates counterclockwise, causing... Multiple curved plates 9 rotate and press against multiple sliding columns 7, causing the slider 6 to move, which in turn moves the rotating shaft 15 and the geared wheel 16. The geared wheel 16 moves the missing gear 14, which in turn moves the sliding plate 13 into the groove 12. The movement of multiple rotating shafts 15 causes multiple laser cutters 17 to move centrally, laser-cutting holes on the surface of the filter element support 2. The turntable 11 rotates, causing multiple sliding plates 13 to rotate. The rotation of the sliding plates 13 causes the missing gear 14 to rotate counterclockwise. The rotation of the missing gear 14 causes multiple geared wheels 16 to rotate. The rotation of the geared wheels 16 causes the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 causes the multiple working laser cutters 17 to perform a one-time annular cut on the surface of the filter element support 2. Compared with traditional laser cutting devices...The laser cutting equipment 1 can adjust the laser cutter 17 according to the different specifications and cutting positions of the filter element bracket 2. It can also perform a single circular cut at multiple cutting positions on the filter element bracket 2, eliminating the need to cut subsequent holes one by one. This improves the cutting efficiency of the laser cutting equipment 1 on the filter element bracket 2. Furthermore, for processing individual filter element brackets 2 of the same specification from the same batch, it eliminates the need to cut the holes on each filter element bracket 2 individually, meeting the needs of large-scale, high-efficiency production.

[0039] Example 2: Please refer to Figure 8 - Figure 11 The difference from embodiment 1 is that a crossbeam 31 is fixedly installed on the bottom surface of each rotating shaft 15, and a movable groove 32 is opened on the bottom surface of each crossbeam 31. A matching movable block 33 is slidably connected inside the movable groove 32. The laser cutter 17 is installed on the bottom surface of the movable block 33. When cutting holes of different sizes on the filter element support 2, the knob 38 is rotated according to the size of the hole to be cut, which drives the threaded rod 36 to rotate into the crossbeam 31. The threaded rod 36 rotates inward, which drives the movable block 33 to move inside the movable groove 32, thereby making the laser cutter 17 follow the movable block 33 for adjustment. During the adjustment of the laser cutter 17, the scale 34 is observed in real time. When the distance between the laser cutter 17 and the rotating shaft 15 is the same as the radius of the hole to be cut, the knob 38 is stopped. The rotation of multiple rotating shafts 15 drives multiple working laser cutters 17 to make a one-time annular cut on the surface of the filter element support 2, which increases the multifunctionality and practicality of the laser cutting equipment 1.

[0040] A ruler 34 is fixedly installed on the surface of any of the crossbars 31, and a rotating groove 35 is opened on the surface of the movable block 33. The setting of the ruler 34 can accurately adjust the position of the laser cutter 17.

[0041] The surface of the crossbar 31 is threaded with a through threaded rod 36, and the inside of the rotating groove 35 is rotatably connected with a matching rotating plate 37. The rotating groove 35 and the rotating plate 37 do not separate. The rotating plate 37 is fixedly connected to one end of the threaded rod 36, and a knob 38 is fixedly installed on the other end of the threaded rod 36.

[0042] The steps of using this invention are as follows: When using the laser cutting device for the oil filter mounting bracket, the existing filter element bracket 2 has different sizes of holes on its surface. When cutting holes of different sizes on the filter element bracket 2, the knob 38 is rotated according to the size of the hole to be cut. The rotation of the knob 38 causes the threaded rod 36 to rotate into the crossbeam 31. The rotation of the threaded rod 36 causes the circular rotating plate 37 to rotate inside the rotating groove 35. The rotation of the threaded rod 36 causes the movable block 33 to move inside the movable groove 32, thereby causing the laser cutter 17 to be adjusted along with the movable block 33. During the adjustment of the laser cutter 17, the scale 34 is observed in real time. When the distance between the laser cutter 17 and the rotating shaft 15 is the same as the radius of the cutting hole, the knob 38 is stopped. Then, through the cutting steps in Example 1, multiple rotating shafts 15 rotate, causing multiple working laser cutters 17 to perform a one-time annular cutting on the surface of the filter element bracket 2, which increases the multifunctionality and practicality of the laser cutting equipment 1.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
