Description

Technical Field

[0001] The invention relates to a valve body processing device, in particular to a valve body ball core hot dip coating device. Background Art

[0002] Ball valves are used for fluid regulation and control and are widely used in chemical, water conservancy, petroleum refining and other industries. As a key component in ball valves, the ball core has high requirements for wear resistance and corrosion resistance. Currently, the ball core is often plated using hot-dip plating to achieve the purpose of wear resistance and corrosion resistance.

[0003] In the process of using the existing ball core hot dip plating device, in order to keep the ball core plating stable, the ball core clamping rod is usually fixed, which makes the ball core can only be plated at a fixed liquid level, and the axial position cannot be changed with the change of the liquid level. Because the elements in the metal solution are at different heights, the elements of the coating are uneven after the plating is completed, and the axial position of the ball core plating can only be adjusted by replacing the clamping rod. At the same time, because the ball core clamping rod is fixed, the ball core cannot move to adjust the coating thickness and uniformity.

[0004] The ball core is taken out of the metal solution, and the metal solution flows along the outer wall of the ball core and drips from the bottom of the ball core. The metal solution solidifies quickly, causing the coating thickness on the upper part of the ball core to be less than that on the lower part of the ball core. The coating thickness is uneven, and workers can only perform secondary grinding and polishing after the plating is completed to improve the uniformity of the core coating, which results in high cost and long processing cycle.

[0005] In summary, how to ensure the uniformity of the coating after the ball valve is plated has become an urgent problem to be solved by researchers in this field. Summary of the invention

[0006] The technical problem to be solved by the present invention is: how to ensure the uniformity of the coating after the ball valve is plated;

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] The present invention is a valve body ball core hot dip plating device, comprising: a plating tank with an opening at the top, in which a metal solution is placed; a clamping claw, which is suitable for clamping a clamping rod fixed on a ball valve; a connecting shaft, the bottom of which is connected to the clamping claw; a centrifugal stirring component, the output end of which is connected to the connecting shaft, and is suitable for centrifugally rotating the ball core separated from the metal solution or stirring the metal solution through the ball core; an immersion component, which is connected to the connecting shaft, and is suitable for driving the connecting shaft to immerse the ball core in the metal solution during the rotation process.

[0009] In this solution, a clamping claw is provided at the bottom of the connecting shaft, and the clamping claw is used to clamp the ball core with a clamping rod. The ball core can be rotated by the centrifugal stirring component, and the ball core can be lifted and lowered by the immersion component. The lifting and rotating movements of the ball core do not interfere with each other and can be performed simultaneously.

[0010] When the ball core needs to be dip-plated, the ball core is immersed in the metal solution through the immersion component. When the liquid level of the metal solution changes, the height of the ball core is adjusted in real time through the immersion component. During the immersion process, the ball core is driven to rotate through the centrifugal stirring component (the immersion component can be used to drive the ball core to rise and fall), thereby stirring the metal solution to ensure the uniformity of the elements in the metal solution, avoid stratification or deposition, and ensure the uniformity of the coating elements;

[0011] When the immersion plating is completed, the ball core is driven to rise through the immersion component, and the ball core is driven to rotate through the centrifugal stirring component, and the excess metal solution is thrown out by centrifugation to ensure the uniformity of the coating thickness; this ensures the uniformity of the coating after the ball valve is plated.

[0012] The clamping rod is integrally formed with the ball core during the casting process. In the subsequent process, the clamping rod needs to be cut to separate the clamping rod from the ball core.

[0013] In order to illustrate the specific structure of the centrifugal stirring assembly, the present invention adopts the centrifugal stirring assembly comprising: a frame, which is fixedly arranged above the immersion plating tank; a rotating motor, which is fixed on the top of the frame, and its rotating end is connected to the connecting shaft;

[0014] In this solution, the rotational force of the motor is transmitted to the connecting shaft, which drives the connecting shaft to rotate and drives the ball core to rotate at the same time.

[0015] To illustrate the specific structure of the immersion assembly, the immersion assembly used in the present invention includes: a slide plate, both sides of which are slidably connected to the inner wall of the frame; a bearing, the outer ring of which is fixed to the middle of the slide plate, and the inner ring of which is fixedly connected to the connecting shaft; a driving assembly, which is suitable for driving the slide plate to rise and fall, and driving the connecting shaft to rise and fall relative to the spline shaft; and the rotating end of the rotating motor is slidably connected to the connecting shaft through the spline shaft;

[0016] In this solution, through the sliding connection between the spline shaft and the connecting shaft, the rotational force can be transmitted to the connecting shaft without affecting the lifting and lowering of the connecting shaft; the slide plate is lifted and lowered by the driving mechanism, and the slide plate and the connecting shaft are fixedly connected by bearings, that is, the rotational force of the connecting shaft is not transmitted to the slide plate, so that the slide plate drives the lifting and lowering of the connecting shaft, and then the lifting and lowering of the ball valve are realized; the two sides of the slide plate can be slidably connected to the inner wall of the frame by a linear rail assembly.

[0017] In order to illustrate the specific structure of the driving mechanism, the driving assembly used in the present invention includes: a driving wheel, which is controlled by a motor to rotate and is arranged on one side of the top of the frame; a driven wheel, which is rotatably arranged on one side of the bottom of the frame and is located below the driving wheel; a synchronous belt, which is rotatably arranged between the driving wheel and the driven wheel; a clamping plate, which connects the synchronous belt and the slide plate;

[0018] In this solution, the lifting movement of the slide plate is realized by the reciprocating motion of the synchronous belt; the lifting movement of the slide plate can also be realized by the connection method of a cylinder, an electric rod or a screw pair.

[0019] In order to limit the lifting range of the slide, avoid the ball valve from contacting the bottom of the immersion tank, and avoid the ball valve from throwing the metal solution out of the immersion tank when performing centrifugal movement, the present invention adopts an upper limit rod downwardly arranged on the top of the frame; a lower limit rod upwardly arranged on the bottom wall of the frame; when the slide moves to abut against the upper limit rod or the lower limit rod, this is the limit state of the slide lifting;

[0020] In this solution, the travel of the slide plate is between the upper limit rod and the lower limit rod, which limits the lifting range of the slide plate.

[0021] Beneficial effects of the present invention: The present invention is a valve body ball core hot dip plating device, the ball core can be rotated by a centrifugal stirring component, and the ball core can be lifted and lowered by an immersion component, and the lifting and lowering and rotating movements of the ball core do not interfere with each other and can be performed simultaneously; when the ball core needs to be dip-plated, the ball core is immersed in a metal solution by an immersion component, and when the liquid level of the metal solution changes, the height of the ball core is adjusted in real time by the immersion component, and during the immersion process, the ball core is driven to rotate by a centrifugal stirring component (the immersion component can be used to drive the ball core to lift and lower), thereby stirring the metal solution to ensure the uniformity of the elements in the metal solution, avoid stratification or deposition, and ensure the uniformity of the coating elements; when the dip plating is completed, the ball core is driven to rise by the immersion component, and the ball core is driven to rotate by the centrifugal stirring component, and the excess metal solution is thrown out by centrifugation to ensure the uniformity of the coating thickness; this ensures the uniformity of the coating after the ball valve is plated.

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] Example 1

[0030] like Figure 1-3 As shown, the present invention is a valve body ball core hot dip plating device, comprising: a plating tank 1 with an opening at the top, in which a metal solution is placed; a clamping jaw 2 is suitable for clamping a clamping rod 31 fixed on a ball valve 3; the bottom of a connecting shaft 4 is connected to the clamping jaw 2; the output end of a centrifugal stirring component is connected to the connecting shaft 4, and the centrifugal stirring component, whose output end is connected to the connecting shaft 4, is suitable for centrifugally rotating the ball core 3 separated from the metal solution or stirring the metal solution through the ball core 3; an immersion component is connected to the connecting shaft 4, and is suitable for driving the connecting shaft 4 to immerse the ball core 3 in the metal solution during the rotation process;

[0031] In this solution, a clamping claw 2 is provided at the bottom of the connecting shaft 4, and the clamping claw 2 is used to clamp the ball core 3 with the clamping rod 31. The ball core 3 can be rotated by the centrifugal stirring component, and the ball core 3 can be lifted and lowered by the immersion component. The lifting and rotating movements of the ball core 3 do not interfere with each other and can be performed simultaneously.

[0032] When the ball core 3 needs to be dip-plated, the ball core 3 is immersed in the metal solution through the immersion component. When the liquid level of the metal solution changes, the height of the ball core 3 is adjusted in real time through the immersion component. During the immersion process, the ball core 3 is driven to rotate through the centrifugal stirring component (the immersion component can be used to drive the ball core 3 to rise and fall), thereby stirring the metal solution to ensure the uniformity of the elements in the metal solution, avoid stratification or deposition, and ensure the uniformity of the plating elements;

[0033] When the immersion plating is completed, the ball core 3 is driven to rise through the immersion component, and the ball core 3 is driven to rotate through the centrifugal stirring component, and the excess metal solution is thrown out by centrifugation to ensure the uniformity of the coating thickness; this ensures the uniformity of the coating on the ball valve 3 after the coating is completed.

[0034] The clamping rod 31 is integrally formed with the ball core 3 during the casting process. In the subsequent process, the clamping rod 31 needs to be cut to separate the clamping rod 31 from the ball core 3 .

[0035] Example 2

[0036] like Figure 1-3 As shown, based on Example 1, in order to illustrate the specific structure of the centrifugal stirring assembly, the present invention adopts the centrifugal stirring assembly comprising: a frame 5 is fixedly arranged above the immersion plating tank 1; a rotating motor 6 is fixed on the top of the frame 5, and the rotating end of the rotating motor 6 is connected to the connecting shaft 4;

[0037] In this solution, the rotational force of the rotating motor 6 is transmitted to the connecting shaft 4, driving the connecting shaft 4 to rotate while driving the ball core 3 to rotate.

[0038] Example 3

[0039] like Figure 1-3 As shown, on the basis of Example 1, in order to illustrate the specific structure of the immersion assembly, the present invention adopts the immersion assembly including: both sides of the slide plate 7 are slidably connected with the inner wall of the frame 5; the outer ring of the bearing 8 is fixed to the middle of the slide plate 7, and the inner ring of the bearing 8 is fixedly connected to the connecting shaft 4; the driving assembly is suitable for driving the slide plate 7 to rise and fall, and driving the connecting shaft 4 to rise and fall relative to the spline shaft 9; and the rotating end of the rotating motor 6 is slidably connected with the connecting shaft 4 through the spline shaft 9;

[0040] In this solution, through the sliding connection between the spline shaft 9 and the connecting shaft 4, the rotational force can be transmitted to the connecting shaft 4 without affecting the lifting and lowering of the connecting shaft 4; the slide plate 7 is lifted and lowered by the driving mechanism, and the slide plate 7 and the connecting shaft 4 are fixedly connected by the bearing 8. The bearing 8 ensures that the ball core 3 is not eccentric during the lifting process, and the rotational force of the connecting shaft 4 is not transmitted to the slide plate 7, so that the slide plate 7 drives the lifting and lowering of the connecting shaft 4, and then the lifting and lowering of the ball valve 3 is realized; the two sides of the slide plate 7 can be slidably connected to the inner wall of the frame 5 by a linear rail assembly.

[0041] Example 4

[0042] like Figure 1-3 As shown, on the basis of Example 3, in order to illustrate the specific structure of the driving mechanism, the present invention adopts a driving assembly comprising: a driving wheel 10 controlled by a motor 11 to rotate and set on the top side of the frame 5; a driven wheel 12 is rotatably set on the bottom side of the frame 5, and the driven wheel 12 is located below the driving wheel 10; a synchronous belt 13 is rotatably set between the driving wheel 10 and the driven wheel 12; a clamping plate 14 connects the synchronous belt 13 and the slide plate 7;

[0043] In this solution, the lifting movement of the slide plate 7 is achieved through the reciprocating motion of the synchronous belt 13; the lifting movement of the slide plate 7 can also be achieved by using a connection method of a cylinder, an electric rod, or a screw pair.

[0044] Example 5

[0045] like Figure 1-3 As shown, on the basis of Example 3, in order to limit the lifting range of the slide plate, prevent the ball valve from contacting the bottom of the immersion tank 1, and prevent the ball valve 3 from throwing the metal solution out of the immersion tank 1 when performing centrifugal movement, the present invention adopts an upper limit rod 15 downwardly provided on the top of the frame 5; a lower limit rod 16 upwardly provided on the bottom wall of the frame 5; when the slide plate 7 moves to abut against the upper limit rod 15 or the lower limit rod 16, this is the limit state of the lifting of the slide plate 7;

[0046] In the present solution, the travel of the slide plate is within the upper limit rod 15 and the lower limit rod 16, which limit the lifting range of the slide plate 7. The lower limit rod 16 is provided to prevent the ball core from contacting the bottom of the immersion plating tank 1 when it is immersed in the immersion plating tank 1, resulting in the inability to coat the bottom of the ball core 3; the purpose of setting the upper limit rod 15 is that when the ball core 3 is separated from the metal solution, the ball core 3 is still in the immersion plating tank 1. When the ball core 3 performs centrifugal motion, the inner wall of the immersion plating tank 1 can prevent the solution from being thrown out, thereby avoiding waste of the metal solution.

[0047] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
