Description
Technical Field
[0001] This invention relates to the field of cutting machine column processing technology, specifically a processing fixture for CNC laser cutting machines. Background Technology
[0002] CNC laser cutting machines are very common in some enterprises and factories. The machine tool column is an important structural component of CNC laser cutting machines, playing a supporting role.
[0003] In this regard, Chinese Patent Application Publication No. CN108723440A discloses a milling column machining fixture and a milling column machining method, belonging to the field of machine tool fixtures. The milling column machining fixture of this invention includes a machine tool worktable and an adjustable shim, the adjustable shim being placed on the machine tool worktable. It also includes a fixed table, which is placed on the adjustable shim. The fixed table includes a base block, a first station, and a second station, which are respectively connected to the side of the base block. Both the first and second stations are cuboids. The first and second stations are used in conjunction with specific surfaces of the milling column. The upper surfaces of the first and second stations are on the same plane.
[0004] However, in actual use, most existing column-mounted fixtures used during machining fix the column in a fixed position, and the bottom surface of the column will abut against the surface of the worktable or the fixture. Therefore, when it is necessary to process the bottom surface of the column, it is necessary to flip the column to expose the bottom surface of the machine tool column. However, this operation is too cumbersome and cannot meet the actual operation requirements. In addition, after flipping the column at a certain angle, it is necessary to re-fix the machine tool column, which has limitations in the overall operation.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Please see Figures 1-11 One embodiment provided by the present invention:
[0035] A processing fixture for a CNC laser cutting machine. The control panel 2, column body 3, transmission mechanism 24, servo motor 34 and telescopic rod 48 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a worktable 1. The control panel 2 is installed on the front surface of the worktable 1. The column body 3 is provided on the surface of the worktable 1. The back of the worktable 1 is fixedly connected to the side frame 4. The lower surface of the side frame 4 is installed with a first connecting block 5 and a second connecting block 6 from left to right. The front surface of the second connecting block 6 is installed with a fixing component. The surface of the worktable 1 is installed with a driving component. The outer surface of the driving component is provided with a stabilizing component. The surface of the driving component is provided with an ejection component.
[0036] The fixing component includes a first limiting frame 7, which is installed on the front surface of the second connecting block 6. A first positioning frame 8 is installed on the left side of the first limiting frame 7. A slot 9 is opened on the left side surface of the first positioning frame 8. A push post 10 is provided inside the slot 9. A first positioning ball 11 is installed on the left side of the push post 10.
[0037] The drive assembly includes a rotating shaft 21, which is inserted and installed on the surface of the worktable 1. A gear body 22 is fixedly connected to the top surface of the rotating shaft 21, and a rack plate 23 is meshed with the back surface of the gear body 22.
[0038] A pressing plate 12 is installed at the end of the push column 10 away from the first positioning ball 11. The pressing plate 12 is installed inside the first positioning frame 8. A mounting spring 13 is provided between the first positioning frame 8 and the pressing plate 12. Telescopic cylinders are installed on both the front and rear sides of the mounting spring 13. The two ends of the telescopic cylinders are connected to the inner wall of the first positioning frame 8 and the left side of the pressing plate 12, respectively. A mounting cylinder 14 is installed on the right side surface of the first limiting frame 7. A mounting rod 15 is provided inside the mounting cylinder 14. A first push frame 16 is provided inside the right side of the mounting cylinder 14. A through groove is opened on the surface of the worktable 1. The through groove is adapted to the top block 40. A mounting frame 43 is installed at the top of the platform 1. A drive motor is installed on the top surface of the mounting frame 43. An output shaft 44 is installed at the output end of the drive motor. A first pressure roller 45 is installed on the right side surface of the output shaft 44. A second pressure roller 46 is installed on the top surface of the output shaft 44. A positioning plate 47 is connected between the second pressure roller 46 and the first pressure roller 45. The outer surface of the positioning plate 47 is attached to the left side surface of the column body 3. A side frame 50 is installed on the top surface of the platform 1. A telescopic rod 48 is installed at the lower end of the side frame 50. A limit roller 49 is provided at the lower end of the telescopic rod 48. A contact spring is provided between the side frame 50 and the limit roller 49.
[0039] When the column body 3 is tilted, its lower left corner will also be tilted. At this time, the surface of the column body 3 will contact the lower surface of the limiting roller 49. The design of the limiting roller 49, the telescopic rod 48, and the contact spring limits the position of the column body 3, preventing it from tilting too much and collapsing. The overall performance is good. Furthermore, during normal fixed contact, the right surface of the first pressure roller 45 fixes the left surface of the column body 3. When the first positioning ball 11 presses against the right side of the column body 3, it adjusts the column body 3 into a tilted state. At this time, the output shaft 44 rotates, and the outer surface of the adjusted positioning plate 47 will fit against the left side surface of the column body 3. The first positioning ball 11 will continue to abut against the right side of the column body 3, limiting the right side surface of the column body 3. Simultaneously, the pushing column 10 is limited in movement by the installed spring 13 and telescopic cylinder. When the pressing plate 12 is no longer abutted, the design of the installed spring 13 allows the pushing column 10 to automatically return to its original position. When the rotating shaft 21 rotates, it meshes with the second bevel gear column 35, causing the second bevel gear column 35 to rotate as well. The second bevel gear 35 drives the second bevel gear 36 to rotate. Then, the second bevel gear 36 meshes with the third bevel gear 37, causing the third bevel gear 37 to rotate. The third bevel gear 37 then drives the rotating cylinder 38 to rotate. As the rotating cylinder 38 rotates, the protruding post 42 inside the arc-shaped groove 41 slides, thereby causing the lifting column 39 to rise. The lifting column 39 then drives the top block 40 to rise. At this time, the top block 40 rises inside the through groove, thus lifting the lower end of the column body 3, providing some support to the column body 3. The lower end of the column body 3 is supported, which facilitates changing the column body 3 to an inclined state. Therefore, it is convenient to process the bottom surface of the column body 3. In this design, when the first positioning ball 11 abuts against the right side surface of the column body 3, the output shaft 44 rotates to change the positioning plate 47 to an inclined state. Then, the lifting column 39 drives the top block 40 to lift. When the column body 3 is adjusted to an inclined state through the cooperation design of the positioning plate 47 and the first positioning ball 11, the top block 40 will support the bottom of the inclined column body 3, and also play an auxiliary support role.
[0040] First, the column body 3 is placed on the surface of the workbench 1. The lower end of the column body 3 then mates with the through groove. When machining the bottom surface of the column body 3 is required, the drive motor is started first, driving the output shaft 44 to rotate. The output shaft 44 then drives the first pressure roller 45 to rotate. The right side surface of the first pressure roller 45 then contacts the left side surface of the column body 3, fixing the left side surface of the column body 3 in place. Next, the servo motor 34 is started, driving the rotating shaft 21 to rotate. The rotating shaft 21 then drives the gear body 22 to rotate counterclockwise. The gear body 22 then drives the rack plate 23 to move to the left. The movement of the rack plate 23 is controlled by a sliding block. The design of 32 and positioning rod 33 limits the movement, while sliding block 32 slides inside the adapter groove, making the overall sliding relatively stable. Then, when rack plate 23 moves to the left, the left surface of rack plate 23 will abut against the right surface of first push frame 16. Subsequently, rack plate 23 will drive first push frame 16 to move to the left. Then, first push frame 16 moves inside mounting cylinder 14 to push mounting rod 15. Subsequently, the pushed mounting rod 15 will squeeze pressing plate 12, so pressing plate 12 will drive push column 10 to move inside slot 9. After push column 10 moves, first positioning ball 11 will abut against the right surface of column body 3, which can fix the right surface of column body 3.
[0041] The stabilizing component includes a second limiting frame 17, which is mounted on the lower surface of the first connecting block 5. A second positioning frame 18 is provided on the front surface of the second limiting frame 17, and a second positioning ball 19 is provided inside the second positioning frame 18. A second pushing frame 20 is provided on the back of the second limiting frame 17. The second limiting frame 17 and the second positioning frame 18 have the same structure as the first limiting frame 7 and the first positioning frame 8. A rotating shaft 21 is inserted and installed on the surface of the worktable 1. A gear body 22 is fixedly connected to the top surface of the rotating shaft 21. A rack plate 23 is meshed and connected to the back of the gear body 22. A transmission mechanism 24 is installed on the top surface of the gear body 22. A first bevel gear 25 is installed at the lower end of the transmission mechanism 24. A first bevel gear 26 is meshed and connected to the lower surface of the first bevel gear 25. A lead screw body 27 is installed inside the first bevel gear 26. A movable ring 29 is installed on the outer surface of the lead screw body 27. An abutment plate 30 is installed on the left side surface of the movable ring 29.
[0042] Then, when the gear body 22 rotates, it will also drive the transmission mechanism 24 to rotate. Then, the transmission mechanism 24 will drive the first bevel gear 25 to rotate. The first bevel gear 25 meshes with the first bevel gear 26. Then, the first bevel gear 26 will drive the lead screw body 27 to rotate. At this time, both the transmission mechanism 24 and the lead screw body 27 are limited by the support frame 28. Then, when the lead screw body 27 rotates, the movable ring 29 on the surface of the lead screw body 27 will move forward on the surface of the lead screw body 27. Then, the movable ring 29 will drive the abutment plate 30 to move forward. When the abutment plate 30 moves forward, the front surface of the abutment plate 30 will abut against the back of the second push frame 20. Thus, the second positioning ball 19 inside the second positioning frame 18 can move forward through the second push frame 20. Thus, the second positioning ball 19 can abut against the back of the column body 3, and the back of the column body 3 can be fixed and positioned.
[0043] The ejector assembly includes a second bevel gear 35, which is mounted on the outer surface of the rotating shaft 21 and meshes with it. A second bevel gear 36 is fixedly connected to the left side surface of the second bevel gear 35, and a third bevel gear 37 is meshed with the outer surface of the second bevel gear 36. A rotating cylinder 38 is mounted on the top surface of the third bevel gear 37, and a lifting column 39 is installed inside the rotating cylinder 38. A top block 40 is mounted on the top surface of the lifting column 39. An arc-shaped groove 41 is formed on the outer surface of the rotating cylinder 38, and a protruding post 42 is provided inside the arc-shaped groove 41. The back of the protruding post 42 is fixedly connected to the lifting column 39. The lower end of the rack plate 23 is installed with... There is a sliding block 32, and a positioning rod 33 is inserted and installed inside the sliding block 32. The positioning rod 33 is installed inside the worktable 1. The surface of the worktable 1 has an adapter groove, which is adapted to the sliding block 32. A support frame 28 is installed on the back of the lead screw body 27. The support frame 28 is movably connected to the transmission mechanism 24. A guide rod 31 is inserted and installed inside the contact plate 30. The back of the guide rod 31 is installed on the front surface of the support frame 28. A servo motor 34 is installed at the lower end of the rotating shaft 21. The servo motor 34 is installed inside the worktable 1. A limit rod is provided at the bottom end of the third bevel gear column 37. The limit rod is inserted and installed inside the worktable 1.
[0044] Meanwhile, when the column body 3 needs to be changed to an inclined state, the output shaft 44 will drive the first pressure roller 45 to rotate, so that the positioning plate 47 will become inclined, and the right side of the column body 3 will also be abutted by the first positioning ball 11, so that the left side surface of the column body 3 is completely in contact with the right side of the positioning plate 47. At this time, the right side of the column body 3 will be pressed and fixed by the first positioning ball 11. Thus, when the column body 3 is in an inclined state, the left, right and back sides of the column body 3 can be fixed and positioned at the same time. Therefore, this operation can facilitate the processing of the bottom surface of the inclined column body 3.
[0045] This design can simultaneously fix and position the column body 3 vertically on the left, right and back sides, and can also fix the column body 3 in an inclined state. Furthermore, the column body 3 in the inclined state can still be fixed and positioned on its left, right and back sides at the same time. Therefore, it is convenient to process the bottom surface of the column body 3 without the need for processes such as flipping the position of the column body 3.
[0046] Working Principle: When using this device, the operator first connects it to an external power source to provide power. The column body 3 is then placed on the surface of the workbench 1, and its lower end mates with the through groove. When machining the bottom surface of the column body 3 is required, the drive motor is started, which rotates the output shaft 44. The output shaft 44 then rotates the first pressure roller 45, causing its right side to contact the left side of the column body 3, thus fixing the left side of the column body 3 in place. Next, the servo motor 34 is started, driving the rotating shaft 21 to rotate. The rotating shaft 21 then drives the gear body 22 to rotate counterclockwise. The gear body 22 then... The moving rack plate 23 moves to the left. At this time, the movement of the rack plate 23 is limited by the design of the sliding block 32 and the positioning rod 33. At the same time, the sliding block 32 slides inside the adapter groove. Then, when the rack plate 23 moves to the left, the left surface of the rack plate 23 will abut against the right surface of the first push frame 16. Subsequently, the rack plate 23 will drive the first push frame 16 to move to the left. Then, the first push frame 16 moves inside the mounting cylinder 14 and pushes the mounting rod 15. Subsequently, the pushed mounting rod 15 will squeeze the pressing plate 12. As a result, the pressing plate 12 will drive the push column 10 to move inside the slot 9. After the push column 10 moves, the first positioning ball 11 will abut against the right surface of the column body 3, which can fix and position the right surface of the column body 3.
[0047] Then, when the gear body 22 rotates, it also drives the transmission mechanism 24 to rotate. The transmission mechanism 24 then drives the first bevel gear 25 to rotate, and the first bevel gear 25 meshes with the first bevel gear 26. Subsequently, the first bevel gear 26 drives the lead screw body 27 to rotate. At this time, both the transmission mechanism 24 and the lead screw body 27 are limited by the support frame 28. Then, when the lead screw body 27 rotates, the movable ring 29 on the surface of the lead screw body 27 moves forward on the surface of the lead screw body 27. Subsequently, the movable ring 29 drives the contact plate 30 to move forward. When the contact plate 30 moves forward, the front surface of the contact plate 30 abuts against the back of the second push frame 20, thereby enabling the second push frame 20 to drive the second... The second positioning ball 19 inside the positioning frame 18 moves forward, so that the second positioning ball 19 can abut against the back of the column body 3, and fix the back of the column body 3. At the same time, when it is necessary to change the column body 3 to an inclined state, the output shaft 44 will drive the first pressure roller 45 to rotate, so that the positioning plate 47 will become inclined, and the right side of the column body 3 will also be abutted by the first positioning ball 11, so that the left side of the column body 3 is completely in contact with the right side of the positioning plate 47. At this time, the right side of the column body 3 will be pressed and fixed by the first positioning ball 11. Thus, when the column body 3 is in an inclined state, the left, right and back sides of the column body 3 can be fixed and positioned at the same time.
[0048] When the rotating shaft 21 rotates, it meshes with the second bevel gear 35, causing the second bevel gear 35 to rotate as well. The second bevel gear 35 then drives the second bevel gear 36 to rotate, which in turn meshes with the third bevel gear 37, causing the third bevel gear 37 to rotate. The third bevel gear 37 then drives the rotating cylinder 38 to rotate. As the rotating cylinder 38 rotates, the protruding post 42 inside the arc groove 41 slides, thereby causing the lifting column 39 to rise. The lifting column 39 then drives the top block 40 to rise, which rises inside the through groove, lifting the lower end of the column body 3 and providing support for it. The lower end of the column body 3 is supported by the top block 40. This is the working principle of the present invention.

Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
