Description

Technical Field

[0001] This invention belongs to the field of alloy processing technology, and specifically discloses a quenching device for processing alloy workpieces. Background Technology

[0002] Quenching is a process in which a workpiece is heated to a certain high temperature and then rapidly cooled with water, oil or air to harden the surface of the workpiece. Local quenching is a common quenching method in workpiece processing. When a workpiece is subjected to local quenching, an intelligent CNC quenching machine tool is used.

[0003] Existing intelligent CNC quenching machine tools include an induction heating structure and a water spray structure distributed below the induction heating structure. In actual use, the clamping structure will drive the alloy workpiece to pass through the interior of the induction heating structure and the water spray structure. When the induction heating structure heats the alloy workpiece to a certain temperature, the clamping structure will drive the heated part of the alloy workpiece to move down, thereby realizing the rapid cooling of the heated part of the alloy workpiece by the water spray structure, and realizing the quenching treatment of the alloy workpiece.

[0004] However, while this intelligent CNC quenching machine tool can indeed achieve good quenching results on alloy workpieces in actual use, it still has some drawbacks, such as:

[0005] Existing intelligent CNC quenching machine tools do not have a good airflow guiding structure. When the induction heating structure heats a certain part of the alloy workpiece, the heat generated by the induction heating structure will move upward with the surface of the workpiece. This will increase the local heating range of the alloy workpiece, thus affecting the performance of the workpiece. At the same time, when the water spray structure rapidly cools down the heated workpiece, the water vapor generated by the cooling of the workpiece will also come into contact with the induction heating structure above. When a lot of water vapor comes into contact with the induction heating structure, it can easily affect the normal operation of the induction heating structure, thus causing damage to the induction heating structure and making it difficult to heat the alloy workpiece. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a quenching apparatus for processing alloy workpieces, so as to solve the problems mentioned above.

[0007] To achieve the above objectives, the present invention provides a quenching device for processing alloy workpieces, comprising a housing and a height adjustment structure distributed inside the housing. An electromagnetic heater and a water spray structure are distributed inside the housing, and the electromagnetic heater and the water spray structure are connected to the height adjustment structure.

[0008] The water spray structure includes an upper fixed ring and a housing that rotates inside the upper fixed ring. A lower fixed ring rotates at the lower part of the housing. An installation ring is fixed to the inner wall of the housing near the lower fixed ring. A sealing ring is fixed to the installation ring near the lower fixed ring. A groove is formed on the lower fixed ring near the sealing ring. A drive structure is connected to the lower part of the housing.

[0009] A branch water pipe is obliquely fixed through the mounting ring. A suction bucket is fixed to the upper end of the branch water pipe and is fixed through the casing. An arc-shaped water pipe is fixed to the lower end of the branch water pipe. The water outlet end of the arc-shaped water pipe passes through the casing, and the water collection end of the arc-shaped water pipe is connected to the inner cavity of the groove.

[0010] In the above technical solution, the outer wall of the housing is further fixed with a water supply tank and a controller. The water supply tank is connected to the inner cavity of the groove through a hose. The height adjustment structure includes a hydraulic cylinder fixed to the upper part of the housing. The output end of the hydraulic cylinder is fixed with a mounting bracket. The mounting bracket is an L-shaped plate structure. The electromagnetic heater and the upper and lower fixing rings are all fixed with the mounting bracket.

[0011] In the above technical solution, the upper and lower parts of the casing are both conical surfaces, the suction bucket is connected to the conical surface of the upper part of the casing, and the arc-shaped water pipe is connected to the conical surface of the lower part of the casing.

[0012] In the above technical solution, the drive structure further includes a rotary motor fixed to the lower part of the mounting bracket, a transmission gear fixed to the output end of the rotary motor, a gear ring meshing on the transmission gear, and the gear ring fixed to the lower part of the housing.

[0013] In the above technical solution, the electromagnetic heater, upper fixing ring, toothed ring, and housing are coaxially distributed, with a gap between the electromagnetic heater and the housing. The workpiece body penetrates through the interior of the housing, and the inner wall of the housing does not contact the workpiece body. The axis of the housing coincides with the axis of the workpiece body. The inner cavity of the suction bucket is connected to the inner cavity of the branch water pipe and the arc-shaped water pipe. The output end of the arc-shaped water pipe is inclined downward, and the receiving end of the suction bucket is inclined upward.

[0014] In the above technical solution, a water collection tank is further fixed at the lower part of the shell, and a mounting base is fixed at the bottom wall of the shell directly below the workpiece body. A drive motor is embedded inside the mounting base, and a chuck is fixed at the output end of the drive motor. The chuck is clamped on the workpiece body.

[0015] In the above technical solution, a fixing tube is further fixed to the inner wall of the casing near the upper fixing ring. The inner cavity of the fixing tube penetrates the casing, and a sealing piece is embedded in the part where the fixing tube penetrates the casing. The fixing tube does not contact the suction bucket.

[0016] In the above technical solution, a sliding column is further provided inside the fixed tube, a magnetic column is fixed at one end of the sliding column near the sealing piece, and an impact rod is fixed at the other end of the sliding column away from the magnetic column, with the impact rod penetrating through the fixed tube.

[0017] In the above technical solution, further, magnetic blocks are fixed at equal intervals on the inner wall of the upper fixing ring, the magnetic poles of the magnetic blocks and the magnetic poles of the magnetic column repel each other, the axes of the sliding column, the magnetic column and the impact rod coincide with the axis of the fixing tube, and the end of the impact rod away from the sliding column contacts the suction bucket.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the water inside the groove of the quenching device passes through the arc-shaped water pipe to cool the part of the workpiece body that is being heated, the inside of the branch water pipe is under negative pressure. At this time, the branch water pipe can collect the water vapor around the workpiece body through the suction bucket. On the one hand, this can prevent the upward-moving water vapor from contacting the electromagnetic heater, thereby preventing the water vapor from affecting the normal operation of the electromagnetic heater. On the other hand, it can prevent the upward-moving water vapor from contacting the workpiece body and heating the surface of the workpiece body, thereby ensuring the local quenching temperature of the workpiece body.

[0020] 2. In this quenching device, the water vapor around the workpiece body can pass through between the casing and the workpiece body, thereby allowing more water vapor to be collected by the suction bucket. It should be noted that when water vapor passes through between the casing and the workpiece body, the water sprayed from the arc-shaped water pipe will come into contact with the water vapor. This can achieve rapid cooling of the water vapor by the water vapor, thereby avoiding heating of the surface of the workpiece body by the water vapor, and thus ensuring the accuracy of local quenching of the workpiece body.

[0021] 3. When the arc-shaped water pipe in the quenching device sprays water onto the workpiece, the rotary motor is started. The output end of the rotary motor can drive the gear ring on the casing to rotate through the transmission gear. When the casing rotates on the mounting frame, the trajectory of the water sprayed from the arc-shaped water pipe is spiral. This can cause the water sprayed from the arc-shaped water pipe to turbulent the water vapor passing between the casing and the workpiece, thereby achieving rapid cooling of the water vapor passing between the casing and the workpiece.

[0022] 4. When the output end of the rotary motor in the quenching device drives the gear ring on the housing to rotate through the transmission gear, the housing can rotate on the mounting frame, and the position of the suction bucket to suck water vapor around the workpiece body will also change accordingly, thereby increasing the range of water vapor sucked by the suction bucket around the workpiece body.

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0035] Example 1: Please refer to Figure 1-9 As shown, the present invention provides a technical solution:

[0036] This invention is a quenching device for processing alloy workpieces, including a shell 1 and a height adjustment structure distributed inside the shell 1. An electromagnetic heater 4 and a water spray structure are distributed inside the shell 1, and the electromagnetic heater 4 and the water spray structure are connected to the height adjustment structure.

[0037] The workpiece body 2 is distributed inside the housing 1. In actual use, the electromagnetic heater 4 and the water spray structure are fitted onto the workpiece body 2. Then, the height adjustment structure can drive the electromagnetic heater 4 and the water spray structure to be distributed on the parts of the workpiece body 2 that need to be processed.

[0038] The water spray structure includes an upper fixed ring 5 and a housing 7 that rotates inside the upper fixed ring 5. A lower fixed ring 51 rotates at the lower part of the housing 7. An installation ring 72 is fixed on the inner wall of the housing 7 near the lower fixed ring 51. A sealing ring 73 is fixed on the installation ring 72 near the lower fixed ring 51. A groove 52 is provided on the lower fixed ring 51 near the sealing ring 73. A drive structure is connected to the lower part of the housing 7.

[0039] When the sealing ring 73 and the lower fixing ring 51 abut, the sealing ring 73 can seal the opening of the groove 52, thereby forming a sealed cavity structure in the inner cavity of the groove 52.

[0040] A branch water pipe 75 is obliquely fixed through the mounting ring 72. The branch water pipe 75 and the arc-shaped water pipe 74 are evenly distributed on the casing 7. A suction bucket 71 is fixed to the upper end of the branch water pipe 75 and is fixed through the casing 7. An arc-shaped water pipe 74 is fixed to the lower end of the branch water pipe 75. The water outlet end of the arc-shaped water pipe 74 passes through the casing 7, and the water collection end of the arc-shaped water pipe 74 is connected to the inner cavity of the groove 52.

[0041] The outer wall of the housing 1 is fixed with a water tank 11 and a controller 13. The water tank 11 is connected to the inner cavity of the groove 52 through a hose. The height adjustment structure includes a hydraulic cylinder 15 fixed on the upper part of the housing 1. The output end of the hydraulic cylinder 15 is fixed with a mounting bracket 14. The mounting bracket 14 is an L-shaped structure. The electromagnetic heater 4, the upper fixing ring 5, and the lower fixing ring 51 are all fixed to the mounting bracket 14.

[0042] After the part of the workpiece body 2 that needs to be quenched is heated, the height adjustment structure drives the electromagnetic heater 4 and the housing 7 to move upward. The distance that the electromagnetic heater 4 and the housing 7 move upward needs to ensure that the water sprayed from the arc water pipe 74 contacts the workpiece body 2. Then, the worker connects the receiving end of the water tank 11 to the external water pump. The external water pump can deliver the cooling water to the inside of the groove 52 through the hose. The water entering the groove 52 can penetrate the arc water pipe 74 and spray it onto the surface of the workpiece body 2. The housing 1 is equipped with a pipe for discharging water.

[0043] When the liquid inside the groove 52 passes through the arc-shaped water pipe 74 to cool down the heated part of the workpiece body 2, the inside of the branch water pipe 75 is under negative pressure. At this time, the branch water pipe 75 can collect the water vapor around the workpiece body 2 through the suction bucket 71. On the one hand, it can prevent the upward-moving water vapor from contacting the electromagnetic heater 4, thereby preventing the water vapor from affecting the normal operation of the electromagnetic heater 4. On the other hand, it can prevent the upward-moving water vapor from contacting the workpiece body 2 and heating the surface of the workpiece body 2, thereby ensuring the local quenching temperature of the workpiece body 2.

[0044] It should be noted that, according to actual needs, the staff can replace the external water pump at the receiving end of the water tank 11 with an external oil pump or an external air pump, so that the arc-shaped water pipe 74 can deliver different cooling media to the surface of the workpiece body 2, so that the heated parts of the workpiece body 2 can achieve different quenching effects.

[0045] Example 2: Please refer to Figure 1-9 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, the water vapor around the workpiece body 2 can penetrate between the shell 7 and the workpiece body 2, thereby enabling more water vapor to be collected by the suction bucket 71. It should be noted that when water vapor penetrates between the shell 7 and the workpiece body 2, the water sprayed from the arc-shaped water pipe 74 will come into contact with the water vapor, which can achieve rapid cooling of the water vapor by the water vapor, thereby avoiding the water vapor from heating the surface of the workpiece body 2, and thus ensuring the accuracy of local quenching of the workpiece body 2.

[0046] The upper and lower parts of the casing 7 are both conical surfaces. The suction bucket 71 is connected to the upper conical surface of the casing 7, and the arc-shaped water pipe 74 is connected to the lower conical surface of the casing 7.

[0047] By setting the upper part of the casing 7 as a conical surface, the range of gas collection around the workpiece body 2 by the suction bucket 71 can be expanded. By setting the lower part of the casing 7 as a conical surface, when the workpiece body 2 is cooled, the water vapor around the workpiece body 2 can pass through between the casing 7 and the workpiece body 2, thereby allowing more water vapor to be collected by the suction bucket 71. It should be noted that when water vapor passes through between the casing 7 and the workpiece body 2, the water sprayed from the arc-shaped water pipe 74 will come into contact with the water vapor. This can achieve rapid cooling of the water vapor by the water liquid, thereby avoiding the water vapor from heating the surface of the workpiece body 2, and thus ensuring the accuracy of local quenching of the workpiece body 2.

[0048] Example 3: Please refer to Figure 1-9As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, when the arc-shaped water pipe 74 sprays water onto the workpiece body 2, the rotary motor 3 is started. The output end of the rotary motor 3 can drive the gear ring 6 on the housing 7 to rotate through the transmission gear 31. When the housing 7 rotates on the mounting bracket 14, the trajectory of the water sprayed by the arc-shaped water pipe 74 is spiral. This can cause the water sprayed by the arc-shaped water pipe 74 to turbulently flow through the water vapor passing between the housing 7 and the workpiece body 2, thereby achieving rapid cooling of the water vapor passing between the housing 7 and the workpiece body 2.

[0049] The drive structure includes a rotary motor 3 fixed to the lower part of the mounting bracket 14. A transmission gear 31 is fixed to the output end of the rotary motor 3. A gear ring 6 meshes on the transmission gear 31. The gear ring 6 is fixed to the lower part of the housing 7.

[0050] The electromagnetic heater 4, upper fixing ring 5, toothed ring 6, and housing 7 are coaxially distributed. There is a gap between the electromagnetic heater 4 and the housing 7. The workpiece body 2 passes through the inside of the housing 7. The inner wall of the housing 7 does not contact the workpiece body 2. The axis of the housing 7 coincides with the axis of the workpiece body 2. The inner cavity of the suction bucket 71 is connected to the inner cavity of the arc-shaped water pipe 74 through the branch water pipe 75. The output end of the arc-shaped water pipe 74 is inclined downward, and the receiving end of the suction bucket 71 is inclined upward.

[0051] A water collection tank 12 is fixed to the lower part of the shell 1. A mounting base 16 is fixed to the bottom wall of the shell 1 directly below the workpiece body 2. A drive motor 18 is embedded inside the mounting base 16. A chuck 17 is fixed to the output end of the drive motor 18. The chuck 17 is clamped on the workpiece body 2.

[0052] According to the actual needs, when the arc-shaped water pipe 74 sprays water on the workpiece body 2, the staff can start the rotary motor 3. The output end of the rotary motor 3 can drive the gear ring 6 on the sleeve 7 to rotate through the transmission gear 31. The sleeve 7 can rotate on the mounting bracket 14. The trajectory of the water sprayed from the arc-shaped water pipe 74 is spiral. This can make the water sprayed from the arc-shaped water pipe 74 turbulent between the sleeve 7 and the workpiece body 2, thereby achieving rapid cooling of the water vapor between the sleeve 7 and the workpiece body 2.

[0053] Meanwhile, workers can also add blades to the outer wall of the casing 7 between the suction bucket 71 and the outlet of the arc-shaped water pipe 74, depending on actual needs. The number of blades is determined according to the actual situation, but it should be noted that the blades must not contact the surface of the workpiece body 2. Please refer to the instruction manual appendix. Figure 6The position where the blades can be added is shown as C. When the guide end of the blades is distributed downward, the airflow driven by the blades can disperse the water sprayed from the arc-shaped water pipe 74. On the one hand, it can achieve rapid cooling of the surrounding area of ​​the workpiece body 2 by the dispersed water liquid. On the other hand, it can prevent water vapor from penetrating between the shell 7 and the workpiece body 2. It can completely prevent water vapor from moving up the surface of the workpiece body 2 during workpiece quenching.

[0054] It should be noted that when blades are added to the casing 7, the blades will drive the airflow around the electromagnetic heater 4. When the operator wants to continue heating the workpiece body 2, the blades will drive the heat generated by the electromagnetic heater 4 to move downward, which will expand the heating range of the electromagnetic heater 4 on the workpiece body 2. The operator can use this method according to the actual needs.

[0055] Example 4: Please refer to Figure 1-9 As shown, based on Embodiment 3, the present invention provides a technical solution. Unlike Embodiment 3, in this embodiment, when the output end of the rotary motor 3 drives the gear ring 6 on the housing 7 to rotate through the transmission gear 31, the housing 7 can rotate on the mounting frame 14, and the position of the suction bucket 71 in sucking water vapor around the workpiece body 2 will also change accordingly, thereby increasing the range of water vapor sucked by the suction bucket 71 around the workpiece body 2.

[0056] A fixing tube 9 is fixed to the inner wall of the casing 7 near the upper fixing ring 5. The inner cavity of the fixing tube 9 penetrates the casing 7. A sealing piece 8 is embedded in the part where the fixing tube 9 penetrates the casing 7. The fixing tube 9 does not contact the suction bucket 71.

[0057] Inside the fixed tube 9, there is a sliding column 93. A magnetic column 92 is fixed at one end of the sliding column 93 near the sealing plate 8. The sealing plate 8 can transmit the magnetism generated by the magnetic block 53 on the magnetic column 92. An impact rod 91 is fixed at one end of the sliding column 93 away from the magnetic column 92. The impact rod 91 and the fixed tube 9 pass through each other.

[0058] Magnetic blocks 53 are fixed at equal intervals on the inner wall of the upper fixed ring 5. The magnetic poles of the magnetic blocks 53 and the magnetic poles of the magnetic column 92 repel each other. The axes of the sliding column 93, the magnetic column 92 and the impact rod 91 coincide with the axis of the fixed tube 9. The end of the impact rod 91 that is away from the sliding column 93 contacts the suction bucket 71.

[0059] In actual use, the suction bucket 71 and the housing 7 are connected by a sealing ring. The sealing ring can deform. When the output end of the rotary motor 3 drives the toothed ring 6 on the housing 7 to rotate through the transmission gear 31, the housing 7 can rotate on the mounting bracket 14. The position of the suction bucket 71 to suck water vapor around the workpiece body 2 will also change accordingly.

[0060] Since the sealing plate 8 can transmit the magnetism generated by the magnetic block 53 on the magnetic column 92, when the magnetic column 92 and the magnetic block 53 are opposite each other, the magnetic column 92 will drive the sliding column 93 to slide inside the fixed tube 9, and the impact rod 91 will penetrate the fixed tube 9 to squeeze the suction bucket 71. At this time, the relative angle between the suction bucket 71 and the workpiece body 2 will also change.

[0061] Since the magnetic blocks 53 are fixed at equal intervals on the inner wall of the upper fixing ring 5, when the magnetic column 92 and the magnetic blocks 53 are not opposite each other, the restoring force of the sealing ring will drive the impact rod 91 to move backward on the fixing tube 9, and the relative angle between the suction bucket 71 and the workpiece body 2 will also be restored. This allows the suction bucket 71 to adjust the angle of water vapor collection in a regular manner, thereby expanding the range of water vapor collection around the workpiece body 2 by the suction bucket 71.

[0062] Working principle: The workpiece body 2 is distributed inside the housing 1. In actual use, the electromagnetic heater 4 and the water spray structure are sleeved on the workpiece body 2. Then, the height adjustment structure can drive the electromagnetic heater 4 and the water spray structure to be distributed on the parts of the workpiece body 2 that need to be treated.

[0063] When the sealing ring 73 and the lower fixing ring 51 abut, the sealing ring 73 can seal the opening of the groove 52, thereby forming a sealed cavity structure in the inner cavity of the groove 52. After the workpiece body 2 heats the part that needs to be quenched, the height adjustment structure drives the electromagnetic heater 4 and the housing 7 to move upward. The distance that the electromagnetic heater 4 and the housing 7 move upward needs to ensure that the water sprayed from the arc water pipe 74 contacts the workpiece body 2. Then, the worker connects the receiving end of the water tank 11 to the external water pump. The external water pump can deliver the cooling water to the inside of the groove 52 through the hose. The water that enters the inside of the groove 52 can penetrate the arc water pipe 74 and spray it onto the surface of the workpiece body 2. The housing 1 is provided with a pipe for discharging water.

[0064] When the liquid inside the groove 52 passes through the arc-shaped water pipe 74 to cool down the heated part of the workpiece body 2, a negative pressure will be formed inside the branch water pipe 75. At this time, the branch water pipe 75 is in a negative pressure state. At this time, the branch water pipe 75 can collect the water vapor around the workpiece body 2 through the suction bucket 71. On the one hand, it can prevent the upward-moving water vapor from contacting the electromagnetic heater 4, thereby preventing the water vapor from affecting the normal operation of the electromagnetic heater 4. On the other hand, it can prevent the upward-moving water vapor from contacting the workpiece body 2 and heating the surface of the workpiece body 2, thereby ensuring the local quenching temperature of the workpiece body 2.

[0065] It should be noted that, according to actual needs, the staff can replace the external water pump at the receiving end of the water tank 11 with an external oil pump or an external air pump, so that the arc-shaped water pipe 74 can deliver different cooling media to the surface of the workpiece body 2, so that the heated parts of the workpiece body 2 can achieve different quenching effects.

[0066] By setting the upper part of the casing 7 as a conical surface, the range of gas collection around the workpiece body 2 by the suction bucket 71 can be expanded. By setting the lower part of the casing 7 as a conical surface, when the workpiece body 2 is cooled, the water vapor around the workpiece body 2 can pass through between the casing 7 and the workpiece body 2, thereby allowing more water vapor to be collected by the suction bucket 71. It should be noted that when water vapor passes through between the casing 7 and the workpiece body 2, the water sprayed from the arc-shaped water pipe 74 will come into contact with the water vapor. This can achieve rapid cooling of the water vapor by the water liquid, thereby avoiding the water vapor from heating the surface of the workpiece body 2, and thus ensuring the accuracy of local quenching of the workpiece body 2.

[0067] According to the actual needs, when the arc-shaped water pipe 74 sprays water on the workpiece body 2, the staff can start the rotary motor 3. The output end of the rotary motor 3 can drive the gear ring 6 on the sleeve 7 to rotate through the transmission gear 31. The sleeve 7 can rotate on the mounting bracket 14. The trajectory of the water sprayed from the arc-shaped water pipe 74 is spiral. This can make the water sprayed from the arc-shaped water pipe 74 turbulent between the sleeve 7 and the workpiece body 2, thereby achieving rapid cooling of the water vapor between the sleeve 7 and the workpiece body 2.

[0068] Meanwhile, workers can also add blades to the outer wall of the casing 7 between the suction bucket 71 and the outlet of the arc-shaped water pipe 74, depending on actual needs. The number of blades is determined according to the actual situation, but it should be noted that the blades must not contact the surface of the workpiece body 2. Please refer to the instruction manual appendix. Figure 6 The position where the blades can be added is shown as C. When the guide end of the blades is distributed downward, the airflow driven by the blades can disperse the water sprayed from the arc-shaped water pipe 74. On the one hand, it can achieve rapid cooling of the surrounding area of ​​the workpiece body 2 by the dispersed water liquid. On the other hand, it can prevent water vapor from penetrating between the shell 7 and the workpiece body 2. It can completely prevent water vapor from moving up the surface of the workpiece body 2 during workpiece quenching.

[0069] It should be noted that when blades are added to the casing 7, the blades will drive the airflow around the electromagnetic heater 4. When the operator wants to continue heating the workpiece body 2, the blades will drive the heat generated by the electromagnetic heater 4 to move downward, which will expand the heating range of the electromagnetic heater 4 on the workpiece body 2. The operator can use this method according to the actual needs.

[0070] In actual use, the suction bucket 71 and the housing 7 are connected by a sealing ring. The sealing ring can deform. When the output end of the rotary motor 3 drives the toothed ring 6 on the housing 7 to rotate through the transmission gear 31, the housing 7 can rotate on the mounting bracket 14. The position of the suction bucket 71 to suck water vapor around the workpiece body 2 will also change accordingly.

[0071] Since the sealing plate 8 can transmit the magnetism generated by the magnetic block 53 on the magnetic column 92, when the magnetic column 92 and the magnetic block 53 are opposite each other, the magnetic column 92 will drive the sliding column 93 to slide inside the fixed tube 9, and the impact rod 91 will penetrate the fixed tube 9 to squeeze the suction bucket 71. At this time, the relative angle between the suction bucket 71 and the workpiece body 2 will also change.

[0072] Since the magnetic blocks 53 are fixed at equal intervals on the inner wall of the upper fixing ring 5, when the magnetic column 92 and the magnetic blocks 53 are not opposite each other, the restoring force of the sealing ring will cause the impact rod 91 to move backward on the fixing tube 9, and the relative angle between the suction bucket 71 and the workpiece body 2 will also be restored. It should be noted that the impact rod 91 is always in contact with the suction bucket 71, which can realize the regular adjustment of the angle of water vapor collection by the suction bucket 71, thereby expanding the range of water vapor collection around the workpiece body 2 by the suction bucket 71.

[0073] 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 principles of 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 claimed invention.
