Description
Technical Field
[0001] The present invention relates to the technical field of plasma surface treatment, and particularly to a plasma treatment device for surface strengthening of titanium alloy tubes. Background Technique
[0002] Low-temperature plasma technology bombards the material surface with high-energy active particles (such as electrons and ions), and can achieve surface nitriding, carburizing or alloying at a relatively low temperature (400 - 500 °C), with both environmental protection and high efficiency. In the prior art, glow discharge plasma nitriding equipment has been used for surface strengthening of titanium alloy plates.
[0003] Existing processing machines for low-temperature plasma treatment of titanium alloy tubes usually can only perform low-quality treatment on the outer wall of titanium alloy tubes unidirectionally, and cannot realize automated and refined plasma treatment operations on the inner and outer walls of titanium alloy tubes. As a result, the strengthening operations on the inner and outer walls of titanium alloy tubes are very cumbersome, and the strengthening effect is not very ideal. For this reason, we propose a plasma treatment device that can perform refined plasma treatment on the inner and outer walls of titanium alloy tubes. Summary of the Invention
[0004] The purpose of the present invention is to provide a plasma treatment device for surface strengthening of titanium alloy tubes to solve the problems raised in the background technique.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A plasma treatment device for surface strengthening of titanium alloy tubes, including a workbench, a moving mechanism is arranged on the upper side of the workbench, and an outer-tube plasma treatment mechanism and an inner-tube plasma treatment mechanism are arranged on the moving mechanism; The outer-tube plasma treatment mechanism includes a plasma treatment machine main body one and a plasma treatment nozzle one, the plasma treatment machine main body one is fixedly connected to the plasma treatment nozzle one, and the plasma treatment nozzle one acts on the outside of the titanium alloy tube; The inner-tube plasma treatment mechanism includes a plasma treatment machine main body two and a plasma treatment nozzle two, the plasma treatment machine main body two is fixedly connected to the plasma treatment nozzle two, and the plasma treatment nozzle two acts on the inside of the titanium alloy tube; The moving mechanism drives the outer-tube plasma treatment mechanism and the inner-tube plasma treatment mechanism to perform all-round plasma treatment and strengthening on the inner and outer sides of the titanium alloy tube.
[0006] Further, the moving mechanism includes a planar moving mechanism, the planar moving mechanism includes an X-axis moving component and a Y-axis moving component, the X-axis moving component is fixedly connected to the upper side of the workbench, and the Y-axis moving component is fixedly connected to the upper side of the X-axis moving component; The X-axis moving component includes a first motor, a first bearing plate, a first gear, a first guide rail, a first slider, and a first rack. The upper side of the workbench is fixedly connected with a first guide rail. The upper side of the first guide rail is slidably connected with a first slider. The upper side of the first slider is fixedly connected with a first bearing plate. One side of the first bearing plate is fixedly connected with a first motor. The output end of the first motor is fixedly connected with a first gear. The outer side of the workbench is fixedly connected with a first rack. The first gear meshes with the first rack. The Y-axis moving component includes a moving frame, a second motor, a second gear, a second rack, a second guide rail, and a second slider. The upper side of the first bearing plate is fixedly connected with a moving frame. The outer side of the moving frame is fixedly connected with a second guide rail. The outer side of the second guide rail is slidably connected with a second slider. The side of the second slider away from the second guide rail is fixedly connected with a second bearing plate. The upper side of the second bearing plate is fixedly connected with a second motor. The output end of the second motor is fixedly connected with a second gear. The outer side of the moving frame is fixedly connected with a second rack. The second gear meshes with the second rack.
[0007] While the smaller titanium alloy pipe rotates and moves forward, control the start of the first motor. The first motor drives the first gear to rotate. The first gear meshes with the first rack, thereby driving the first bearing plate, the first slider, and the moving frame to slide on the first guide rail, and then adjusting the position of the moving frame. At the same time, start the second motor. The second motor drives the second gear to rotate. The second gear meshes with the second rack, thereby driving the second bearing plate and the second slider to slide along the second guide rail. Since the second bearing plate is fixedly connected with the linear drive component, the position of the linear drive component and the outer plasma processor in the plane can be adjusted, so that the plasma treatment nozzle 1 moves to the position corresponding to the outer wall of the smaller titanium alloy pipe. Then start the fourth motor. The fourth motor drives the lead screw to rotate, thereby driving the moving block to perform a linear motion along the guide rod, so that the moving block drives the outer plasma processor fixedly connected thereto to move up and down, making the plasma treatment nozzle 1 approach the outer wall of the smaller titanium alloy pipe. Start the first plasma processor main body, so that the first plasma processor main body generates low-temperature plasma and shoots it out through the plasma treatment nozzle 1, acting on the outer wall of the smaller titanium alloy pipe to perform plasma treatment on it. Since the smaller titanium alloy pipe rotates and moves forward, the plasma treatment nozzle 1 can uniformly treat its outer wall, realizing the strengthening of its outer wall by bombarding its outer wall with high-energy active particles through the low-temperature plasma technology. Further, the off-tube plasma processing mechanism includes a pipe fitting conveying mechanism. There are multiple groups of the pipe fitting conveying mechanisms. The pipe fitting conveying mechanism includes a third motor, a chain, a first sprocket, a second sprocket, a first fixed seat, a rotating shaft, a guiding wheel, and a second fixed seat. The upper side of the workbench is fixedly connected with evenly distributed second fixed seats and first fixed seats. One end of the second fixed seat is rotatably connected with a guiding wheel. The inner side of the first fixed seat is rotatably connected with a rotating shaft. One side of the workbench is fixedly connected with a third motor through a rectangular block. The output end of the third motor is fixedly connected with a first sprocket. One end of the rotating shaft is fixedly connected with a second sprocket. The first sprocket and the second sprocket are meshed with the chain on the outside. The guiding wheel and the rotating shaft cooperate to convey titanium alloy pipes.
[0008] When dealing with titanium alloy pipes with a smaller diameter, place the smaller titanium alloy pipes in batches between the rotating shaft and the guiding wheel. By starting the third motor, the third motor drives the first sprocket to rotate. The first sprocket drives the second sprocket to rotate synchronously through the chain engagement, and then drives the rotating shaft to rotate. While the rotating shaft is rotating, under the action of the oblique guiding of the guiding wheel, the smaller titanium alloy pipes rotate and move forward continuously. Further, a fixed frame is fixedly connected to one side of the workbench. The moving assembly further includes two linear driving components fixedly connected between the fixed frame and the inner plasma processor. The two linear driving components drive the inner plasma processor to perform planar movement. A linear driving component is also fixedly connected between the Y-axis moving assembly and the outer plasma processor.
[0009] After the outer wall of the smaller titanium alloy pipe is processed by the first plasma processing nozzle, the smaller titanium alloy pipe moves to a position corresponding to the inner plasma processor. At this time, start the two linear driving components at the inner plasma processor. One linear driving component drives the inner plasma processor to move closer to the smaller titanium alloy pipe, and the other linear driving component drives the inner plasma processor to move downward, so that the second plasma processing nozzle is located at the center of the smaller titanium alloy pipe. Then the smaller titanium alloy pipe moves to the nozzle of the second plasma processing nozzle. At this time, start the second plasma processor main body, so that the second plasma processing nozzle emits low-temperature plasma, and then uniformly performs plasma processing on the inner wall of the smaller titanium alloy pipe, achieving the purpose of automatically performing uniform plasma processing on the inner and outer sides of the smaller titanium alloy pipe. After the internal processing is completed, start one linear driving component again to drive it away from the smaller titanium alloy pipe, and then the smaller titanium alloy pipe is conveyed to the next process through the pipe fitting conveying mechanism. Furthermore, the in-tube plasma processing mechanism includes a motion mechanism, which includes an annular drive member, a motion component, an adjustment component, and a power component. On the side of the second bearing plate away from the second motor, there is a fixed connection with the annular drive member. Inside the annular drive member, there is a motion component, and the adjustment component and the power component are installed on the motion component; The annular drive member includes a mounting plate, a fifth motor, a third gear, a gear ring, a fixed ring, and a rotating ring. On the side of the second bearing plate away from the second motor, there is a fixed connection with the mounting plate. On the upper side of the mounting plate, there is a fixed connection with the fifth motor. The output end of the fifth motor is fixedly connected with the third gear. On the side of the mounting plate away from the second bearing plate, there is a fixed connection with the fixed ring. Inside the fixed ring, there is a rotatable connection with the rotating ring. On the side of the rotating ring away from the fixed ring, there is a fixed connection with the gear ring, and the third gear meshes with the gear ring.
[0010] Furthermore, the motion component includes a circular frame, fixed rods, springs, moving blocks, connecting rods, legs, and rollers. Inside the gear ring, there are multiple groups of circular frames. Adjacent circular frames are fixedly connected. The circular frame is fixedly connected with evenly distributed fixed rods. On the fixed rods, there is a sliding connection with the moving blocks. On the outside of the moving blocks, there is a rotatable connection with the connecting rods. On the outside of the circular frame, there are evenly distributed legs rotatably connected. The legs and the connecting rods are rotatably connected. At the end of the legs, there is a rotatable connection with the rollers. Outside the fixed rods and between the inner side wall of the circular frame and the moving blocks, there are sleeves of springs.
[0011] Furthermore, the adjustment component includes a sixth motor, a threaded rod, a connecting block, and a connecting ring. Inside the circular frame, there is a fixed connection with the sixth motor. The output end of the sixth motor is fixedly connected with the threaded rod. On the outside of the threaded rod, there is a threaded connection with the connecting block. On the outside of the connecting block, there is a fixed connection with the connecting ring, and the connecting ring is fixedly connected with the moving block.
[0012] When dealing with titanium alloy tubes with a larger diameter, the larger titanium alloy tube is sleeved outside the motion component. Start the sixth motor. The sixth motor drives the threaded rod to rotate, so that the threaded rod drives the connecting block, the connecting ring, and the moving block to slide along the fixed rod, and then drives the connecting rod to rotate, and then drives the legs and the rollers to rotate, so that the rollers are in close contact with the larger titanium alloy tube; Furthermore, the power component includes a seventh motor, a belt, and a connecting shaft. On one group of motion components, there is a fixed installation of a protective housing. Inside the protective housing, there is a fixed connection with the seventh motor. On one side of one group of rollers, there is a fixed connection with the connecting shaft. The output ends of the connecting shaft and the seventh motor are both fixedly connected with belt pulleys, and there is a belt transmission connection between the two belt pulleys.
[0013] Start motor seven, and motor seven drives a set of belt pulleys to rotate. The set of belt pulleys drives another set of belt pulleys to rotate through a belt, and then drives the rollers to rotate through a connecting shaft, thereby driving the larger titanium alloy pipe to move linearly outside the moving assembly. At this time, start the plasma processor main body two, and the plasma processor main body two emits low-temperature plasma through the plasma processing nozzle two. While the larger titanium alloy pipe is moving linearly, since the plasma processing nozzle two is located at the inner center position thereof, the inner wall of the pipe is thus subjected to plasma processing; Furthermore, a linear drive assembly is fixedly connected between the outer plasma processor and the annular drive member. The inner plasma processor is fixedly connected to the lower side wall of the mounting plate, and the plasma processing nozzle two is fixedly connected to the inner side wall of the circular frame.
[0014] Start motor five, and motor five drives gear three to rotate. Gear three meshes with and drives the gear ring and the rotating ring to rotate annularly along the fixed ring, thereby driving the linear drive assembly and the outer plasma processor to rotate annularly around the larger titanium alloy pipe. The linear drive assembly drives the plasma processing nozzle one to approach the outer wall of the larger titanium alloy pipe. Start the plasma processor main body one, so that the plasma processing nozzle one emits low-temperature plasma. While it is rotating annularly and the larger titanium alloy pipe is moving linearly, the purpose of performing all-round and refined plasma processing on the outer wall of the larger titanium alloy pipe is achieved. After the processing is completed, the larger titanium alloy pipe is transported to the corresponding next process by the planar moving mechanism, thereby achieving the effect of performing all-round and refined plasma processing on both the inner and outer sides of the larger titanium alloy pipe.
[0015] Furthermore, the linear drive assembly includes a motor four, a connecting plate, a lead screw, a guide rod, and a moving block. The motor four is fixedly connected to the outside of the connecting plate. The output end of the motor four is fixedly connected to an adjusting assembly. Two groups of guide rods are fixedly connected to the inside of the connecting plate. The outside of the connecting plate is threadedly connected with the moving block, and the moving block slides on the outside of the guide rod.
[0016] Compared with the prior art, the present invention provides a plasma processing device for surface strengthening of titanium alloy pipes, which has the following beneficial effects: 1. The plasma treatment device for surface strengthening of titanium alloy tubes, through the cooperation of the fixed frame 7, the tube conveying mechanism 5, two sets of linear drive components 6 fixedly connected to the fixed frame 7, the planar movement mechanism, the outer plasma processor, and the inner plasma processor, realizes the purpose of automatically performing uniform plasma treatment on the inner and outer sides of smaller titanium alloy tubes. It solves the problem that the existing technology can only perform low-quality treatment on the outer wall of titanium alloy tubes unilaterally, and cannot perform automatic and refined plasma treatment operations on the inner and outer walls of titanium alloy tubes. As a result, the strengthening operations on the inner and outer walls of titanium alloy tubes are very cumbersome, and the strengthening effect is not satisfactory.
[0017] 2. The plasma treatment device for surface strengthening of titanium alloy tubes, through the cooperation of the movement mechanism, the planar movement mechanism, the outer plasma processor, and the inner plasma processor, realizes the purpose of automatically performing all-round and refined plasma treatment on the inner and outer sides of larger titanium alloy tubes at the same time. It achieves the effect of matching different plasma treatment schemes for titanium alloy tubes of different sizes and specifications, and improves the plasma strengthening effect.

Gear 2 224 meshes with Rack 2 225, thereby driving Carrier Plate 2 223 and Slide Block 2 227 to slide along Guide Rail 2 226. Since Carrier Plate 2 223 is fixedly connected to Linear Drive Assembly 6, the position of Linear Drive Assembly 6 and the outer plasma processor 3 in the plane can be adjusted, so that Plasma Processing Nozzle 1 32 moves to the position corresponding to the outer wall of the smaller titanium alloy pipe.

The sixth motor 831 drives the threaded rod 832 to rotate, causing the threaded rod 832 to drive the connecting block 833, the connecting ring 834, and the moving block 824 to slide along the fixing rod 822. Thereby driving the connecting rod 825 to rotate, and further driving the legs 826 and the rollers 827 to rotate, so that the rollers 827 are in close contact with the larger titanium alloy pipe. Further, the power assembly 84 includes a seventh motor 841, a belt 842, and a connecting shaft 843. A protective housing is fixedly installed on a set of motion assemblies 82. The seventh motor 841 is fixedly connected to the inner side of the protective housing. A connecting shaft 843 is fixedly connected to one side of a set of rollers 827. Pulley wheels are fixedly connected to both the connecting shaft 843 and the output end of the seventh motor 841. A belt 842 is drivingly connected between the two pulley wheels.
[0030] Start the seventh motor 841. The seventh motor 841 drives a set of pulley wheels to rotate. A set of pulley wheels drives another set of pulley wheels to rotate through the belt 842, and then drives the rollers 827 to rotate through the connecting shaft 843, thereby driving the larger titanium alloy pipe to perform a linear motion on the outside of the motion assembly 82. At this time, start the second plasma processor main body 41. The second plasma processor main body 41 emits low-temperature plasma through the second plasma treatment nozzle 42. While the larger titanium alloy pipe is performing a linear motion, since the second plasma treatment nozzle 42 is located at the central position inside it, the inner wall of the larger titanium alloy pipe is subjected to plasma treatment. Further, a linear drive assembly 6 is fixedly connected between the outer plasma processor 3 and the annular drive member 81. The inner plasma processor 4 is fixedly connected to the lower side wall of the mounting plate 811. The second plasma treatment nozzle 42 is fixedly connected to the inner side wall of the circular frame 821.
[0031] Start the fifth motor 812. The fifth motor 812 drives the third gear 813 to rotate. The third gear 813 meshes with and drives the gear ring 814 and the rotating ring 816 to perform an annular rotation along the fixed ring 815, thereby driving the linear drive assembly 6 and the outer plasma processor 3 to perform an annular rotation around the larger titanium alloy pipe. The linear drive assembly 6 drives the first plasma treatment nozzle 32 to approach the outer wall of the larger titanium alloy pipe. Start the first plasma processor main body 31, so that the first plasma treatment nozzle 32 emits low-temperature plasma. While it is performing an annular rotation and the larger titanium alloy pipe is performing a linear motion, the purpose of performing all-round and refined plasma treatment on the outer wall of the larger titanium alloy pipe is achieved. After the treatment is completed, the larger titanium alloy pipe is transported to the corresponding next process by the planar moving mechanism 2, thereby achieving the effect of performing all-round and refined plasma treatment on both the inner and outer sides of the larger titanium alloy pipe.
[0032] Further, the linear drive assembly 6 includes a fourth motor 61, a connecting plate 62, a lead screw 63, a guide rod 64, and a moving block 65. The fourth motor 61 is fixedly connected to the outer side of the connecting plate 62. The output end of the fourth motor 61 is fixedly connected to an adjusting assembly 83. Two guide rods 64 are fixedly connected to the inner side of the connecting plate 62. The moving block 65 is threadedly connected to the outer side of the connecting plate 62. The moving block 65 slides on the outer side of the guide rod 64.
[0033] The specific usage method and function of this embodiment: During use, first, when dealing with titanium alloy pipes with a smaller diameter, a batch of the smaller titanium alloy pipes are placed between the rotating shaft 56 and the guiding wheel 57. By starting the third motor 51, the third motor 51 drives the first sprocket 53 to rotate. The first sprocket 53 drives the second sprocket 54 to rotate synchronously through the engagement of the chain 52, thereby driving the rotating shaft 56 to rotate. While the rotating shaft 56 is rotating, under the action of the oblique guiding of the guiding wheel 57, the smaller titanium alloy pipes move forward continuously while rotating; While the smaller titanium alloy pipes are rotating and moving forward, control the start of the first motor 211. The first motor 211 drives the first gear 213 to rotate. The first gear 213 meshes with the first rack 216, thereby driving the first bearing plate 212, the first slider 215, and the moving frame 221 to slide on the first guide rail 214, thereby adjusting the position of the moving frame 221. At the same time, start the second motor 222. The second motor 222 drives the second gear 224 to rotate. The second gear 224 meshes with the second rack 225, thereby driving the second bearing plate 223 and the second slider 227 to slide along the second guide rail 226. Since the second bearing plate 223 is fixedly connected to the linear driving assembly 6, the position of the linear driving assembly 6 and the outer plasma processor 3 in the plane can be adjusted, so that the first plasma treatment nozzle 32 moves to the position corresponding to the outer wall of the smaller titanium alloy pipe. Then start the fourth motor 61. The fourth motor 61 drives the lead screw 63 to rotate, thereby driving the moving block 65 to move linearly along the guide rod 64, so that the moving block 65 drives the outer plasma processor 3 fixedly connected to it to move up and down, so that the first plasma treatment nozzle 32 approaches the outer wall of the smaller titanium alloy pipe; Start the first plasma processor main body 31, so that the first plasma processor main body 31 generates low-temperature plasma and shoots it out through the first plasma treatment nozzle 32, acting on the outer wall of the smaller titanium alloy pipe to perform plasma treatment on it. Since the smaller titanium alloy pipe rotates and moves forward at the same time, the first plasma treatment nozzle 32 can perform homogenization treatment on its outer wall, realizing the strengthening of its outer wall by bombarding its outer wall with high-energy active particles through the low-temperature plasma technology; After the outer wall of the smaller titanium alloy pipe is processed by the plasma treatment nozzle 1 - 32, the smaller titanium alloy pipe moves to a position corresponding to the inner plasma treatment machine 4. At this time, the two sets of linear drive components 6 at the inner plasma treatment machine 4 are started. One set of linear drive components 6 drives the inner plasma treatment machine 4 to move closer to the smaller titanium alloy pipe, and the other set of linear drive components 6 drives the inner plasma treatment machine 4 to move downward, so that the plasma treatment nozzle 2 - 42 is located at the center of the smaller titanium alloy pipe. Subsequently, the smaller titanium alloy pipe moves to the nozzle of the plasma treatment nozzle 2 - 42. At this time, the plasma treatment machine main body 2 - 41 is started, so that the plasma treatment nozzle 2 - 42 emits low-temperature plasma, thereby uniformly plasma-treating the inner wall of the smaller titanium alloy pipe, achieving the purpose of automatically and uniformly plasma-treating the inner and outer sides of the smaller titanium alloy pipe. After the inner side is processed, one set of linear drive components 6 is started again to drive it away from the smaller titanium alloy pipe, and then the smaller titanium alloy pipe is transported to the next process through the pipe conveying mechanism 5; When dealing with a larger-diameter titanium alloy pipe, the larger titanium alloy pipe is sleeved on the outside of the moving component 8 - 2. The motor 6 - 831 is started, and the motor 6 - 831 drives the threaded rod 8 - 32 to rotate, so that the threaded rod 8 - 32 drives the connecting block 8 - 33, the connecting ring 8 - 34, and the moving block 8 - 24 to slide along the fixed rod 8 - 22, thereby driving the connecting rod 8 - 25 to rotate, and then driving the support leg 8 - 26 and the roller 8 - 27 to rotate, so that the roller 8 - 27 is in close contact with the larger titanium alloy pipe; The motor 7 - 841 is started, and the motor 7 - 841 drives a set of belt pulleys to rotate. A set of belt pulleys drives another set of belt pulleys to rotate through the belt 8 - 42, and then drives the roller 8 - 27 to rotate through the connecting shaft 8 - 43, thereby driving the larger titanium alloy pipe to move linearly on the outside of the moving component 8 - 2. At this time, the plasma treatment machine main body 2 - 41 is started, and the plasma treatment machine main body 2 - 41 emits low-temperature plasma outward through the plasma treatment nozzle 2 - 42. While the larger titanium alloy pipe is moving linearly, since the plasma treatment nozzle 2 - 42 is located at the center position of its inner side, the inner wall of the larger titanium alloy pipe is plasma-treated; Meanwhile, start the fifth motor 812. The fifth motor 812 drives the third gear 813 to rotate. The third gear 813 meshes with and drives the gear ring 814 and the rotating ring 816 to perform circular rotation along the fixed ring 815, thereby driving the linear drive assembly 6 and the outer plasma processor 3 to perform circular rotation around the larger titanium alloy pipe. The linear drive assembly 6 drives the first plasma treatment nozzle 32 to approach the outer wall of the larger titanium alloy pipe. Start the first plasma processor main body 31 to cause the first plasma treatment nozzle 32 to emit low-temperature plasma. While performing circular rotation and linear movement of the larger titanium alloy pipe, the purpose of performing all-round and refined plasma treatment on the outer wall of the larger titanium alloy pipe is achieved. After the treatment, the planar movement mechanism 2 drives the larger titanium alloy pipe to the corresponding next process, thereby achieving the effect of performing all-round and refined plasma treatment on both the inner and outer sides of the larger titanium alloy pipe.
