Description

Technical Field

[0001] The present invention relates to the technical field of flame cutting, and specifically to a flame cutting device based on a double-station manipulator. Background Art

[0002] Electric contact precious metal materials are a new type of materials with excellent properties that meet the high-performance requirements of modern electrical equipment. For example, Ag-MAX electric contact materials are mainly used as highly reliable precision electric contact materials, such as electric contact points, brushes, conductive rings, and winding materials. They are key basic materials that are irreplaceable in high-tech fields such as modern national defense, aerospace, weaponry and ships, and electronic information. When manufacturing and processing electric contact precious metal materials, sometimes it is necessary to cut the materials, including laser cutting, electrical discharge machining, flame cutting, etc.

[0003] Flame cutting uses the high temperature generated during the combustion of iron oxide to cut electric contact precious metal materials. The fuels used in flame cutting include acetylene, propane, and natural gas. When using flame cutting to cut electric contact precious metal materials, it is necessary to cut out a specific shape on the surface of the electric contact precious metal materials according to the cutting requirements. Therefore, it is necessary to control the trajectory of flame cutting to meet the cutting requirements.

[0004] Most traditional flame cutting devices are in a single-station mode, that is, only one flame cutting head is used to cut and process electric contact precious metal materials. The flame cutting head of one cutting station can meet the cutting of different shapes. However, when cutting a cutting trajectory with symmetric characteristics, the cutting efficiency of the single-station flame cutting head is low, and it is difficult to meet the high-efficiency cutting requirements for this type of shape cutting. Summary of the Invention

[0005] To solve the problem that most traditional flame cutting devices only have one flame cutting head to cut and process electric contact precious metal materials, and for a cutting trajectory with symmetric characteristics, the cutting efficiency of the single-station flame cutting head is low, the present invention is realized through the following technical solutions: A flame cutting device based on a double-station manipulator, including a guide rail, a sliding seat arranged on the surface of the guide rail, and a support cross frame fixedly installed on the surface of the sliding seat. The double-station manipulator includes a first cutting module and a second cutting module. The first cutting module and the second cutting module are respectively slidably arranged on the lower surface of the support cross frame through a first guide seat and a second guide seat;

[0006] The lower surfaces of the first guide seat and the second guide seat are both provided with adjusting disks that can rotate horizontally. The lower surface of the adjusting disk is horizontally slidably provided with a support plate, and a flame nozzle is installed below the support plate through a hydraulic rod;

[0007] The movement of the sliding seat on the surface of the guide rail is the first movement, the movement of the first guide seat or the second guide seat under the lower surface of the support cross-frame is the second movement, the horizontal rotation of the adjustment disc is the third movement, and the movement of the support plate on the lower surface of the adjustment disc is the fourth movement. By using one or more combinations of these four movements, flame cutting is performed on the electro-contact precious metal material plates with different requirements for cutting shapes.

[0008] Further, the bottom surfaces of the first guide seat and the second guide seat are both semi-circular structures. When the first guide seat contacts the second guide seat, the two semi-circular bottom surfaces are combined into a circle.

[0009] The bottom surfaces of the first guide seat and the second guide seat are both provided with arc guide grooves with a T-shaped cross-section, and the upper surface of the adjustment disc is fixedly provided with an arc rail with a T-shaped cross-section, and the arc rail is adapted to the arc guide groove.

[0011] A connection component is provided between the two adjustment discs. When the first guide seat contacts the second guide seat, under the action of the connection component, the adjustment disc can rotate relative to the first guide seat and the second guide seat, and at the same time, the two adjustment discs are in a relatively fixed state.

[0012] Further, limit card slots are opened on the bottom surfaces of the first guide seat and the second guide seat.

[0013] The connection component includes an adjustment rod, a limit cam and a tooth piece. The adjustment rod is slidably arranged inside the adjustment disc corresponding to the second guide seat. A compression spring is arranged between the adjustment rod and the adjustment disc. Tooth parts one are arranged on the upper surfaces at both ends of the adjustment rod, and a tooth part two is arranged inside the adjustment rod near one end of the first guide seat. One end of the tooth part two of the adjustment rod is located outside the adjustment disc.

[0014] A limit sliding groove is opened inside the adjustment disc corresponding to the first guide seat. When the second guide seat approaches the first guide seat, the adjustment rod can enter the limit sliding groove.

[0015] The limit cam is rotatably installed inside the adjustment disc corresponding to the inner end of the limit sliding groove and inside the adjustment disc corresponding to the inner end of the adjustment rod. A gear surface is arranged on the surface of the limit cam, and the gear surface can be meshed with the corresponding tooth part one. When the limit cam rotates, it can cooperate with the limit card slot.

[0016] The tooth piece is arc-shaped and is rotatably installed inside the adjusting disk corresponding to the first guiding seat. When the adjusting rod enters the limiting sliding groove, the tooth part two at this end of the adjusting rod can engage with the tooth piece.

[0017] Furthermore, the rotating disk is rotatably installed inside the adjusting disk corresponding to the first guiding seat. An arc-shaped adjusting groove is formed on the upper surface of the rotating disk. The tooth piece is rotatably installed inside the adjusting disk through a rotating rod.

[0018] A T-shaped rod is slidably installed inside the adjusting disk corresponding to the first guiding seat along the radial direction of the rotating disk. One end of the T-shaped rod close to the rotating rod is slidably connected to the rotating rod. A guide post is arranged on the lower surface of the end of the T-shaped rod close to the rotating disk. The guide post cooperates with the adjusting groove.

[0019] Furthermore, a driving groove is arranged on the bottom surface of the supporting cross frame. A linear tooth track is arranged inside the driving groove. Driving gears are rotatably installed on the upper surfaces of the first guiding seat and the second guiding seat. The driving gears are engaged with the linear tooth track.

[0020] A guiding groove with a T-shaped cross section is formed on the bottom surface of the supporting cross frame. Supporting guide blocks with a T-shaped cross section are fixedly installed on the upper surfaces of the first guiding seat and the second guiding seat. The supporting guide blocks cooperate with the guiding groove.

[0021] Furthermore, a connecting block is fixedly installed on the upper surface of the supporting plate. An opening groove is formed on the lower surface of the adjusting disk. A screw rod is rotatably installed inside the opening groove. The connecting block is threadedly connected to the surface of the screw rod.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. For the flame cutting device based on the double-station manipulator, by arranging a double-station first cutting module and a second cutting module on the lower surface of the supporting cross frame, and sequentially arranging an adjusting disk, a supporting plate and a flame nozzle below the first guiding seat and the second guiding seat, the flame nozzle has various motion forms to meet the cutting requirements of different shaped trajectories of the electro-contact precious metal material plate. At the same time, the adjusting disk cooperates with the first guiding seat and the second guiding seat to realize the combination of the first cutting module and the second cutting module. The two flame nozzles are used in combination to simultaneously cut and process the electro-contact precious metal material plate with a cutting trajectory having a symmetric feature, so as to improve the efficiency of flame cutting of the electro-contact precious metal material plate.

[0024] 2. The flame cutting device based on a two-station manipulator sets a turntable, a T-shaped rod, a toothed piece, and a limit chute in one adjustment disk, sets an adjustment rod and a compression spring in the other adjustment disk, and sets a first tooth part at both ends of the adjustment rod to cooperate with the limit cam inside the adjustment disk, and sets a second tooth part at one end to cooperate with the toothed piece. When the first guide seat and the second guide seat are close but not in contact, by rotating the turntable, the first guide seat and the second guide seat can be made to contact and dock, and at the same time, the adjustment disk can rotate relative to the first guide seat and the second guide seat. This can not only avoid excessive extrusion when the first guide seat and the second guide seat are combined, but also ensure that the two flame nozzles rotate coaxially when rotating with the adjustment disk.

Detailed implementation manner

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] The embodiment of the flame cutting equipment based on the double-station manipulator is as follows:

[0041] Please refer to Figures 1 - 10 , a flame cutting equipment based on a double-station manipulator, including a cutting table 1, a guide rail 2, a sliding seat 3 arranged on the surface of the guide rail 2, and a supporting cross frame 31 fixedly installed on the surface of the sliding seat 3. The guide rails 2 are distributed on both sides of the cutting table 1. The supporting cross frame 31 is erected above the cutting table 1 through the sliding seat 3. A driving component (this driving component is a prior art and is not shown in the figure) is arranged inside the sliding seat 3 to enable it to move on the surface of the guide rail 2. The double-station manipulator includes a first cutting module 4 and a second cutting module 5. The first cutting module 4 and the second cutting module 5 are respectively slidably arranged on the lower surface of the supporting cross frame 31 through a first guiding seat 41 and a second guiding seat 51.

[0042] The bottom surface of the support cross-frame 31 is provided with a driving groove 311, and a linear tooth track is arranged inside the driving groove 311. Driving gears 6 are rotatably installed on the upper surfaces of the first guide seat 41 and the second guide seat 51. A motor for controlling the rotation of the driving gear 6 is installed in the inner cavity 62. The driving gear 6 meshes with the linear tooth track. By using the rotation of the driving gear 6, the first cutting module 4 or the second cutting module 5 is controlled to move on the lower surface of the support cross-frame 31.

[0043] The bottom surface of the support cross-frame 31 is provided with a guide groove 312 with a T-shaped cross-section. Support guide blocks 61 with a T-shaped cross-section are fixedly installed on the upper surfaces of the first guide seat 41 and the second guide seat 51. The support guide blocks 61 cooperate with the guide groove 312 for the moving support of the first cutting module 4 and the second cutting module 5 on the lower surface of the support cross-frame 31.

[0044] Adjusting discs 8 capable of horizontal rotation are arranged on the lower surfaces of the first guide seat 41 and the second guide seat 51. A support plate 9 is horizontally slidably arranged on the lower surface of the adjusting disc 8. A flame spray head 11 is installed below the support plate 9 through a hydraulic rod 10. A feed pipe 16 is connected and installed at the upper end of the flame spray head 11. The feed pipe 16 provides fuel for the flame spray head 11 to generate flame spraying. The feed pipe 16 is a deformable pipe fitting. A wire box 313 is installed on the upper surface of the support cross-frame 31. The feed pipe 16 is arranged in the wire box 313 to ensure the normal movement of the flame spray head 11.

[0045] The bottom surfaces of the first guide seat 41 and the second guide seat 51 are both semi-circular structures. When the first guide seat 41 contacts the second guide seat 51, the two semi-circular bottom surfaces are combined into a circle. Arc guide grooves 7 with a T-shaped cross-section are provided on the bottom surfaces of the first guide seat 41 and the second guide seat 51. An arc rail 81 with a T-shaped cross-section is fixedly arranged on the upper surface of the adjusting disc 8. The arc rail 81 is adapted to the arc guide groove 7. When the adjusting disc 8 can rotate relative to the first guide seat 41 and the second guide seat 51, the arc rail 81 cooperates with the arc guide groove 7 to support the rotation of the adjusting disc 8.

[0046] Inner cavities 62 are provided on the opposite side surfaces of the first guide seat 41 and the second guide seat 51. An adjusting motor 411 is fixedly installed in the inner cavity 62 of the first guide seat 41. A turntable 15 is fixedly installed at the output end of the adjusting motor 411. An annular groove is provided on the inner side surface of the corresponding adjusting disc 8 of the second guide seat 51. When the first guide seat 41 contacts the second guide seat 51, the turntable 15 is accommodated by using the annular groove.

[0047] A connecting component is arranged between the two adjusting discs 8. When the first guide seat 41 contacts the second guide seat 51, under the action of the connecting component, the adjusting disc 8 can rotate relative to the first guide seat 41 and the second guide seat 51, and at the same time, the two adjusting discs 8 are in a relatively fixed state.

[0048] The bottom surfaces of the first guide seat 41 and the second guide seat 51 are both provided with limit card slots 71; the connecting component includes an adjusting rod 13, a limit cam 12 and a tooth piece 14. The adjusting rod 13 is slidably arranged inside the corresponding adjusting disc 8 of the second guide seat 51. A compression spring 133 is arranged between the adjusting rod 13 and the adjusting disc 8. When the second guide seat 51 approaches the first guide seat 41, under the action of the compression spring 133, the adjusting rod 13 does not slide relative to the adjusting disc 8 on which it is installed until the second guide seat 51 contacts the first guide seat 41. Then, under the action of force, the adjusting rod 13 can slide relative to the adjusting disc 8 on which it is installed. Tooth parts one 131 are arranged on the upper surfaces at both ends of the adjusting rod 13, and a tooth part two 132 is arranged inside the adjusting rod 13 near one end of the first guide seat 41. One end of the tooth part two 132 of the adjusting rod 13 is located outside the adjusting disc 8.

[0049] A limit sliding groove 83 is provided inside the adjusting disc 8 corresponding to the first guide seat 41. When the second guide seat 51 approaches the first guide seat 41, the adjusting rod 13 can enter the limit sliding groove 83.

[0050] The limit cam 12 is rotatably installed inside the adjusting disc 8 corresponding to the inner end of the limit sliding groove 83 and inside the adjusting disc 8 corresponding to the inner end of the adjusting rod 13. The surface of the limit cam 12 is provided with a gear surface, and the gear surface can mesh with the corresponding tooth part one 131. When the limit cam 12 rotates, it can cooperate with the limit card slot 71. When the adjusting rod 13 moves towards the inside of the adjusting disc 8 corresponding to the first guide seat 41, the tooth part one 131 on its surface can mesh with the gear surface on the surface of the corresponding limit cam 12, driving the limit cam 12 to rotate and separating the limit cam 12 from the limit card slot 71. At this time, the adjusting disc 8 can rotate relative to the first guide seat 41 and the second guide seat 51.

[0051] The tooth piece 14 is arc-shaped and is rotatably installed inside the adjusting disc 8 corresponding to the first guide seat 41. When the adjusting rod 13 enters the limit sliding groove 83, the tooth part two 132 at this end of the adjusting rod 13 can mesh with the tooth piece 14.

[0052] After the tooth part two 132 at one end of the adjusting rod 13 enters the inside of the limit sliding groove 83 and meshes with the tooth piece 14, by using the rotation of the tooth piece 14, the adjusting rod 13 is driven to continue moving towards the inside of the limit sliding groove 83, and the second guide seat 51 is further driven to approach the first guide seat 41 by the adjusting rod 13.

[0053] The turntable 15 is rotatably installed inside the adjusting disc 8 corresponding to the first guide seat 41. An arc-shaped adjusting groove 151 is provided on the upper surface of the turntable 15. The tooth piece 14 is rotatably installed inside the adjusting disc 8 through a rotating rod.

[0054] A T-shaped rod 141 is slidably installed inside the adjusting disk 8 corresponding to the first guiding seat 41 along the radial direction of the turntable 15. One end of the T-shaped rod 141 close to the rotating rod is slidably connected to the rotating rod. A guide post is provided on the lower surface of the end of the T-shaped rod 141 close to the turntable 15. The guide post cooperates with the adjusting groove 151. When the turntable 15 starts to rotate, the turntable 15 rotates relative to the adjusting disk 8. The adjusting groove 151 cooperates with the guide post to drive the T-shaped rod 141 to move. The T-shaped rod 141 drives the tooth piece 14 to rotate through the rotating rod.

[0055] When it is necessary to combine the two flame nozzles 11 together, the second guiding seat 51 is moved closer to the first guiding seat 41 until the second tooth part 132 of the adjusting rod 13 meshes with the tooth piece 14. At this time, the adjusting motor 411 is used to drive the turntable 15 to rotate. The initial rotation of the turntable 15 drives the tooth piece 14 to rotate. The tooth piece 14 meshes with the second tooth part 132 to drive the second guiding seat 51 to continue moving closer to the first guiding seat 41 until the second guiding seat 51 contacts the first guiding seat 41. At this time, the tooth piece 14 continues to drive the adjusting rod 13 to move. At this time, the adjusting rod 13 slides relative to the adjusting disk 8 corresponding to the second guiding seat 51. The first tooth parts 131 at both ends of the adjusting rod 13 mesh with the gear surfaces on the surface of the limiting cam 12 to drive the limiting cam 12 to rotate, so that the limiting cam 12 is separated from the limiting card slot 71. At this time, under the restriction of the limiting sliding groove 83, the adjusting rod 13 no longer moves. Correspondingly, the rotation of the turntable 15 relative to the adjusting disk 8 is restricted. When the turntable 15 continues to rotate, it will drive the adjusting disk 8 to rotate together. The two adjusting disks 8 will rotate synchronously under the combined action of the arc track 81 and the arc guide groove 7.

[0056] This design can adjust the connection relationship between the adjusting disk 8 and the first guiding seat 41 or the second guiding seat 51. At the same time, when the adjusting disk 8 needs to rotate, it can drive its rotation. In addition, when the second guiding seat 51 moves closer to the first guiding seat 41, before they contact, the rotation of the turntable 15 is used to complete the final contact docking, which can avoid excessive extrusion between the first guiding seat 41 and the second guiding seat 51, and at the same time ensure the coaxiality when the two flame nozzles 11 rotate after the first guiding seat 41 contacts the second guiding seat 51.

[0057] A connecting block 91 is fixedly installed on the upper surface of the support plate 9. A slot is opened on the lower surface of the adjusting disk 8. A screw rod 82 is rotatably installed inside the slot. A motor for driving the screw rod 82 to rotate is installed on the side surface of the adjusting disk 8. The connecting block 91 is threadedly connected to the surface of the screw rod 82. By rotating the screw rod 82, the support plate 9 is driven to move on the lower surface of the adjusting disk 8.

[0058] The movement of the slide 3 on the surface of the guide rail 2 is the first movement, the movement of the first guide seat 41 or the second guide seat 51 on the lower surface of the supporting cross frame 31 is the second movement, the horizontal rotation of the adjusting disk 8 is the third movement, and the movement of the support plate 9 on the lower surface of the adjusting disk 8 is the fourth movement. By using one or more of the four movements to cooperate, flame cutting is performed on electrical contact precious metal material plates with different cutting shape requirements.

[0059] In the first movement mode, two flame nozzles 11 can be used to perform linear cutting on the electrical contact precious metal material sheet along the direction of the guide rail 2, and the two flame nozzles 11 operate independently of each other; in the second movement mode, two flame nozzles 11 can be used to perform linear cutting on the electrical contact precious metal material sheet along the direction of the length of the supporting cross frame 31, and the two flame nozzles 11 operate independently of each other; the first movement and the second movement are perpendicular to each other, so when the first movement is combined with the second movement, the flame nozzle 11 can perform various shape trajectories on the electrical contact precious metal material sheet. In this case, any one of the flame nozzles 11 can be used to perform cutting processing on the electrical contact precious metal material sheet with a set shape trajectory, or two flame nozzles 11 can be used to perform cutting processing on the surface of the electrical contact precious metal material sheet with the same size shape trajectory.

[0060] By means of the third movement, the first guide seat 41 and the second guide seat 51 are brought into contact and matched together, and the electrical contact precious metal material plate is circularly cut by the combination of two flame nozzles 11; the cutting radius of the circular cutting by the combination of the two flame nozzles 11 is adjusted by the fourth movement; the fourth movement is combined with the third movement, and the position of the support plate 9 is adjusted by the rotation of the adjustment disk 8 in the third movement, so that the direction of the fourth movement of the support plate 9 is parallel to the direction of the first movement. When the fourth movement is adjusted to a state perpendicular to the second movement, the fourth movement is combined with the second movement, and the two flame nozzles 11 are combined at the same time to cut various shape trajectories that are symmetrical along the supporting cross frame 31.

[0061] Working principle of flame cutting equipment:

[0062] The electrical contact precious metal material sheet to be cut is placed on the surface of the cutting table 1, and the movement mode of the flame nozzle 11 in the first cutting module 4 and / or the second cutting module 5 is selected according to the shape of the electrical contact precious metal material sheet to be cut. The movement trajectory of the flame nozzle 11 is controlled by controlling a combination of one or more of the first movement, the second movement, the third movement and the fourth movement, and the flame nozzle 11 is used to cut the required shape of the electrical contact precious metal material sheet on the surface of the electrical contact precious metal material sheet.

[0063] refer to Figure 11, when it is necessary to perform a straight-line cutting along the direction of the guide rail 2 on the surface of the electro-contact precious metal material plate, by controlling the movement of the first motion control flame nozzle 11, the electro-contact precious metal material plate can be processed by flame cutting. When it is necessary to perform a straight-line cutting along the width direction of the cutting table 1 on the surface of the electro-contact precious metal material plate, by controlling the movement of the second motion control flame nozzle 11, the electro-contact precious metal material plate can be processed by flame cutting; reference Figure 12 , by combining the first motion and the second motion, the movement of the flame nozzle 11 can be controlled according to a set trajectory, so as to perform a cutting of a specific shape on the surface of the electro-contact precious metal material plate.

[0064] Reference Figure 13 , after the combination of the two flame nozzles 11, by using the third motion, a circular trajectory cutting can be performed on the surface of the electro-contact precious metal material plate; when the fourth motion of moving the support plate 9 relative to the adjusting disk 8 by using the third motion is adjusted to be perpendicular to the second motion, at this time, the fourth motion and the third motion are combined, and the two flame nozzles 11 can be used to simultaneously perform flame cutting on the electro-contact precious metal material plates with symmetrical cutting shapes, so as to improve the efficiency of the cutting process of the electro-contact precious metal material plates.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
