Description

Technical Field

[0001] The invention relates to the technical field of valve processing equipment, in particular to a surface treatment device for valve processing. Background Art

[0002] The casting blank of the valve is a thin-walled shell part with a relatively complex structure. The casting requires a smooth surface and clear casting characters, especially a dense structure, and must not have defects such as pores, shrinkage holes, looseness, cracks and sand inclusions. In order to meet the above requirements, a series of process measures need to be taken during casting, such as selecting highly refractory molding materials and controlling the moisture content of the molding sand. During molding, the sand should be compacted in layers to ensure the hardness of the sand mold, a reasonable pouring and riser system should be adopted, and the pouring speed and temperature should be strictly controlled. After a series of processes are completed, an anti-oxidation coating needs to be applied to the valve surface, and the applied coating needs to be dried. In order to prevent dust from adhering to the coating during the drying process, the valve body is mostly transferred to a drying device in the prior art.

[0003] For example, a valve surface treatment device and treatment process disclosed in publication number CN116727203A and a valve surface treatment device disclosed in publication number CN114178154A, both of the above schemes use a sealing structure to dry the paint on the surface of the valve body. However, when the valve body is transferred from the paint to the inside of the drying equipment, it needs to be exposed to the external environment, so there is also a risk of dust adhesion during the movement. In addition, during long-distance transportation, the outer wall of the valve body is prone to contact with the side wall of the transfer equipment or the drying equipment, which causes the paint to fall off, thereby affecting the effect of the surface treatment. In view of this, we propose a surface treatment device for valve processing. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] A surface treatment device for valve processing, such as Figure 1-Figure 8As shown, it includes a box body 1; a loading port and a unloading port are respectively provided on the sides of the box body 1, and a unloading plate can be additionally provided at the unloading port to facilitate the automatic unloading operation of the valve body, and a block is rotatably connected to the unloading plate, and the block structure can assist the unloading operation of the valve body, and a switching mechanism 2 is provided in the middle of the box body 1, and the switching mechanism 2 can switch the workstations of the valve body processing, so that the valve body can be switched between different processing operations.

[0040] Specifically, the switching mechanism 2 includes a rotating seat 21, which is rotatably connected to the bottom end of the box body 1. The rotating seat 21 structure can support the entire switching mechanism 2, so that the rotating seat 21 can rotate inside the box body 1. A support column 22 is fixedly connected to the top of the rotating seat 21, and the support column 22 structure is fixed to the top of the rotating seat 21, and the support column 22 is a hollow structure. A support frame 23 is fixedly connected to the side of the support column 22, and the support frame 23 is provided with multiple groups. The support frame 23 is tilted from top to bottom in sequence. The tilted and staggered support frame 23 can facilitate the drying operation of the painted valve body and prevent the paint on the surface of the upper valve body from dripping onto the lower valve body.

[0041] On this basis, a telescopic mechanism 3 is provided on the switching mechanism 2, and the telescopic mechanism 3 includes a moving seat 31. The moving seat 31 is a "T"-shaped structure. The moving seat 31 is slidably connected to the top of the support frame 23. The structure of the moving seat 31 can support the valve body. At the same time, the moving seat 31 with a T-shaped structure can facilitate the insertion of the valve body into the moving seat 31, so that it is convenient to perform surface treatment operations on the outer wall of the valve body when supporting the valve body. The bottom end of the moving seat 31 is fixedly connected to a support rod 32, and the support rod 32 structure can support the moving seat 31. The end of the support rod 32 is slidably connected to the inner side of the support frame 23, so that the moving seat 31 is supported by the support rod 32 during the horizontal movement of the moving seat 31.

[0042] It is worth mentioning that the support column 22 is rotatably connected to a reciprocating screw rod 34 inside, and the reciprocating screw rod 34 is meshedly connected to a driving block 35 on the outside. The driving block 35 is rotatably connected to a driving rod 36 on the side, and the end of the driving rod 36 is rotatably connected to a driving seat 37. The driving seat 37 is slidably connected to the support frame 23, and the moving seat 31 is connected to the side of the driving seat 37. The driving seat 37 can drive the moving seat 31 to move synchronously during the sliding process, thereby horizontally moving the valve body placed on the moving seat 31, and the driving block 35 can be reciprocatingly lifted and lowered under the drive of the reciprocating screw rod 34, and the horizontal movement of the driving seat 37 is controlled by the side driving rod 36.

[0043] In addition, a driving mechanism 4 is provided at the bottom of the switching structure, and the driving mechanism 4 includes a driving frame 41, and the driving frame 41 is rotatably connected to the bottom of the rotating seat 21. The driving frame 41 structure can drive the rotating seat 21 or the reciprocating screw rod 34 to realize the rotation of the rotating seat 21 or the driving rotation of the reciprocating screw rod 34. A ratchet 42 is fixedly connected to the bottom end of the inner side of the rotating seat 21 and the bottom end of the reciprocating screw rod 34, and a ratchet 43 is rotatably connected to the inner side of the driving frame 41 and the outer side of the driving frame 41. The ratchet 43 and the ratchet 42 are meshed with each other, and the transmission assembly 44 of the ratchet 42 and the ratchet 43 can be driven unidirectionally, so that the driving of the rotating seat 21 by the driving frame 41 and the driving of the reciprocating screw rod 34 by the driving frame 41 do not interfere with each other.

[0044] It is worth noting that the bottom end of the driving frame 41 is connected with a transmission assembly 44, which can transmit the driving frame 41 so that the driving frame 41 rotates forward or reversely. The transmission assembly 44 includes a transmission gear 441, which is fixedly connected to the bottom end of the driving frame 41. The transmission gear 441 corresponds to the center of the circle of the driving frame 41, so that the rotation of the transmission gear 441 can drive the driving frame 41 to rotate synchronously. The two sides of the transmission gear 441 are respectively meshed with a driving gear 1 442 and a driving gear 2 443. The rotation directions of the driving gear 1 442 and the driving gear 2 443 are opposite, so that the transmission gear 441 can be driven in different directions. At the same time, the driving gear 1 442 is a 3 / 4 residual gear structure, and when the driving gear 1 442 rotates, it drives the reciprocating screw 1 34, so that the reciprocating screw 1 34 performs a single reciprocating drive operation on the driving block 35. The driving gear 2 443 is a 1 / 4 residual gear structure. After a single rotation of the driving gear 2 443, the rotating seat 21 can be rotated 90 degrees through the transmission gear 441. The bottom of the driving gear 2 443 is fixedly connected to the driven gear 1 444, and the side of the driven gear 1 444 is meshedly connected to the driven gear 2 445. The driven gear 1 444 and the driving gear 2 443 are on the same rotation axis, so that the rotation of the driven gear 1 444 can drive the driving gear 2 443 to rotate. At the same time, the driven gear 2 445 structure can change the direction of the driven gear 1 444 and the driving gear 2 443, so that the same driving structure can drive the driving gear 1 442 and the driving gear 2 443 at the same time, and make the driving gear 1 442 and the driving gear 2 443 rotate in opposite directions.

[0045] The bottom ends of the driven gear 2 445 and the driving gear 1 442 are both fixedly connected with a linkage rod 446, and the linkage rod 446 structure can support and drive the driven gear 2 445 and the driving gear 1 442. A transmission disc 447 is rotatably connected inside the housing 1, and a transmission belt 448 is sleeved on the outside of the transmission disc 447 and the linkage rod 446. The transmission disc 447 structure drives the driving gear 1 442 and the driven gear 2 445 at the same time through the transmission belt 448.

[0046] On this basis, a dual-axis motor 45 is fixedly connected to the bottom end of the box body 1. The dual-axis motor 45 structure can drive the drive disk to make the drive disk rotate continuously. In actual use, a reduction gearbox can be connected at both ends of the dual-axis motor 45 to reduce the output speed of the dual-axis motor 45.

[0047] Example 2

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, on the basis of Example 1, the output shaft at one end of the dual-axis motor 45 is connected to a transmission rod 46, and the transmission rod 46 is slidably connected in the middle of the transmission disk 447. The outer side of the transmission rod 46 is a prismatic structure, so that the transmission rod 46 can maintain the driving rotation of the transmission disk 447 when moving along the direction of the transmission rod 46, and the top of the inner side of the transmission rod 46 is a prismatic structure, and the bottom of the transmission rod 46 is a cylindrical structure. At the same time, the output shaft at one end of the dual-axis motor 45 is a prismatic structure. When the transmission rod 46 moves to the point where the output shaft of the dual-axis motor 45 and the transmission rod 46 cooperate with each other, the transmission disk 447 can be driven by the dual-axis motor 45. At the same time, when the transmission rod 46 moves upward and disengages from the output shaft at one end of the dual-axis motor 45, the output shaft at one end of the dual-axis motor 45 immediately idles inside the cylindrical structure and will not drive the transmission rod 46. At this time, the valve body can be surface treated without closing the dual-axis motor 45. The output shaft at the other end of the dual-axis motor 45 is connected to a timing component 47, which can move the transmission rod 46. After a set time, the transmission rod 46 can be moved and reset, and then cooperate with the output shaft at one end of the dual-axis motor 45 again.

[0049] In this embodiment, the timing assembly 47 includes a linkage gear set 471, which is two bevel gears meshing vertically with each other, one of which is rotatably connected to the bottom end of the box body 1 through a rod-shaped support structure, and the dual-axis motor 45 drives the rod-shaped support structure through a belt, and the linkage gear set 471 can convert the driving force of the vertically arranged dual-axis motor 45 into a horizontal driving force. A reciprocating screw rod 472 is fixedly connected to the linkage gear set 471, and a timing block 473 is meshed and connected to the outer side of the reciprocating screw rod 472. The reciprocating screw rod 472 rotates continuously under the drive of the dual-axis motor 45, and causes the outer timing block 473 to perform periodic and continuous reciprocating movement. The timing block 473 is slidably connected to the side of the moving block 474, and the inner side of the moving block 474 is fixedly connected to the buffer spring 475. The side of the moving block 474 is abutted against the timing seat 476, and the side of the timing seat 476 is provided with a timing groove 477. The moving block 474 is slidably connected inside the timing groove 477, and the top of the timing seat 476 is connected to the bottom of the transmission rod 46 through the timing spring 478. The timing groove 477 is a trapezoidal structure. When the moving block 474 moves inside the timing groove 477, the timing seat 476 can be driven to realize the timing lifting operation of the timing seat 476. At the same time, there is a height difference at the bottom of one side of the timing groove 477, that is, the timing groove 477 is a gradually rising structure, and the head and tail ends of the timing groove 477 are connected to each other. The height difference inside the timing groove 477 can limit the sliding of the moving block 474, so that the moving block 474 can slide around the timing groove 477 of the trapezoidal structure, and avoid the moving block 474 from swinging back and forth at the bottom of the timing groove 477 of the trapezoidal structure when reciprocating.

[0050] Example 3

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, on the basis of Example 2, a paint spraying mechanism 5 and a drying mechanism 6 are provided inside the box body 1. The paint spraying mechanism 5 can spray paint on the valve body, and the drying mechanism 6 can dry the valve body after painting, so that the valve body after painting can be automatically dried to avoid dust adhesion during movement that affects the effect of the valve body surface treatment.

[0052] In this embodiment, the paint spraying mechanism 5 includes a paint spraying box 51, which is fixedly connected to the inner wall of the box body 1. A paint spraying device 52 is connected to the inside of the paint spraying box 51. The paint spraying box 51 can seal the entire paint spraying environment to prevent the paint from diffusing into the inside of the box body 1 and affecting the overall surface treatment operation. The paint spraying device 52 is arranged on both sides of the paint spraying box 51. When performing the paint spraying operation, paint spraying processing can be performed on both sides of the valve body at the same time.

[0053] In addition, the drying mechanism 6 includes an oven 61, which is fixedly connected to the inner wall of the box body 1. A feed port 62 is provided on the side of the oven 61 and the paint spray box 51. The feed port 62 structure can facilitate the valve body to enter the oven 61 or the paint spray box 51, and the drive seat 37 structure can cover the feed port 62. The inner side of the feed port 62 and the outer side of the drive seat 37 are fixedly connected with a contact spring 63. The contact spring 63 structure can start the internal structure of the oven 61 after the paint spray device 52 through the movement of the drive seat 37, so that the paint spray device 52 and the oven 61 are closed when the valve body does not enter the paint spray box 51 or the oven 61, thereby reducing energy consumption. An induction heating coil 64 is fixedly connected inside the oven 61. The induction heating coil 64 structure can heat the metal valve body separately, thereby avoiding heating the entire interior of the oven 61. While reducing energy consumption, the valve body can be quickly heated up, thereby improving the drying efficiency of the valve body. A fan 65 is connected to the side of the induction heating coil 64. The fan 65 can quickly discharge the moisture generated by drying, thereby improving the drying efficiency of the paint on the surface of the valve body.

[0054] When the surface treatment device for valve processing of the present invention is used, the valve bodies are first installed and placed on the moving seat 31 one by one, and then the double-axis motor 45 is started. In the initial state, the middle position of the driving gear 1 442 is meshed with the transmission gear 441, and the driving gear 2 443 is disengaged from the transmission gear 441. After starting, the double-axis motor 45 drives the transmission rod 46 and the linkage gear set 471 respectively. When the transmission rod 46 rotates, it drives the transmission disk 447 to rotate, and drives the driving gear 1 442 and the transmission gear 4412 to rotate through the transmission belt 448 outside the transmission disk 447. The transmission gear 4412 drives the driving gear 2 443 to rotate in the opposite direction through the meshed transmission gear 4411. When the driving gear 1 442 rotates, it drives the transmission gear 441 and the driving frame 41 to rotate forward, and the driving frame 41 then drives the reciprocating screw rod 1 34 to rotate through the ratchet 43. The driving block 35 moves upward under the drive of the reciprocating screw rod 1 34 and moves the driving seat 37 and the moving seat 31 inward through the driving rod 36, and the moving seat 31 then moves the valve body from the loading port to the inside of the box body 1. While the driving gear 1 442 drives the transmission gear 441, the reciprocating screw rod 2 472 continues to rotate under the drive of the linkage gear set 471 and drives the timing block 473 and the moving block 474 inside the timing block 473, and the moving block 474 then moves along the timing slot 477, and the moving block 474 moves from one end of the top of the timing slot 477 to the other end. When the driving seat 37 is completely moved to the end of the support frame 23, the driving gear 1 442 is disengaged from the transmission gear 441, and the driving gear 2 443 is meshed with the transmission gear 441. At this time, the transmission gear 441 and the driving frame 41 rotate in the opposite direction. The driving frame 41 rotating in the opposite direction will not drive the reciprocating screw rod 1 34. The driving frame 41 drives the rotating seat 21 to rotate during the rotation process, and the support column 22 and the support frame 23 drive the valve body to rotate accordingly. When the rotating seat 21 rotates 90°, the driving gear 2 443 is disengaged from the transmission gear 441 again, and the support column 22 stops rotating, and the valve body and the paint spray box 51 are positioned in correspondence with each other. Subsequently, the driving gear 1 442 is meshed with the transmission gear 441 again, and the reciprocating screw rod 1 34 is driven again. The driving block 35 then descends and pushes the driving seat 37 and the moving seat 31 outward through the driving rod 36, and the valve body on the moving seat 31 moves to the inside of the paint spray box 51. The driving seat 37 moves synchronously to the feed port 62, and the contact spring piece 63 on the driving seat 37 contacts the contact spring piece 63 at the feed port 62, connecting the inside of the paint spray box 51, and the paint spray device 52 then sprays paint on the surface of the valve body.When the rotating seat 21 is close to rotating to 90°, that is, when the driving gear 1 442 rotates close to the initial position, the moving block 474 moves to the other end of the top of the timing slot 477. When the rotating seat 21 rotates subsequently, the moving block 474 slides from the top of the timing slot 477 to the bottom of the timing slot 477, and the moving block 474 then drives the timing seat 476 to continuously rise, and the timing seat 476 then drives the transmission rod 46 to rise synchronously, and after the rotating seat 21 rotates to 90° and the driving gear 1 442 completely rotates to the initial position, the transmission rod 46 moves to a state of disengagement from the output shaft of the dual-axis motor 45, and the driving frame 41 stops rotating. At the same time, the linkage gear set 471 continues to rotate under the drive of the dual-axis motor 45, and the moving block 474 slides along the bottom of the timing slot 477. At this time, the subsequent support frame 23 rotates to the loading port of the box body 1, and the operator can place the valve body to be processed on the moving seat 31. When the moving block 474 slides from one end of the bottom of the timing groove 477 to the other end, the paint spraying device 52 completes the painting operation on the valve body. At the same time, when the moving block 474 rises along the timing groove 477, the timing seat 476 descends under the drive of the moving block 474 and moves the transmission rod 46 downward. At this time, the prismatic groove inside the transmission rod 46 may be misaligned with the prismatic output end of the dual-axis motor 45. At this time, the timing spring 478 is stretched accordingly, and when the transmission rod 46 and the output shaft of the dual-axis motor 45 correspond to each other, the timing spring 478 moves the transmission rod 46 downward by elasticity, and the transmission disk 447 is driven by the dual-axis motor 45 again to rotate, thus forming a stroke. When the valve body is moved to the inside of the oven 61 in the same way, the valve body moves to the inside of the induction heating coil 64, and the valve body is heated under the induction heating of the induction heating coil 64, and then the valve body and the paint on the surface are heated and dried from the inside to the outside, and the fan 65 runs synchronously and assists in drying the valve body. When the valve body is dried, it is moved to the outside of the discharge port in the same way, and the operator can remove the valve body that has completed the surface treatment.
