Description

Technical Field

[0001] The invention belongs to the technical field of end cap processing and conveying, in particular to a end cap processing and feeding device. Background Art

[0002] The head is a key pressure-bearing component used to seal the ends of equipment such as pressure vessels and storage tanks. It is usually made of metal sheets through stamping and spinning processes into specific geometric shapes such as hemispherical, elliptical and dished shapes. As the core component of the pressure vessel, the head has excellent pressure-bearing performance, sealing and structural stability, and is ensured to be defect-free through non-destructive testing. The head is widely used in petrochemical, nuclear power, pharmaceutical and other fields.

This application drives the flaw detector to rotate through the vertical arm rotation assembly to perform non-destructive testing on the end heads, increase the detection range of the flaw detector, and improve the detection efficiency.

Traditional non-destructive testing equipment uses rotating flaw detectors to perform testing, which can effectively improve the detection range. However, this still has obvious limitations, especially when dealing with non-destructive penetration testing tasks for large quantities of heads. Traditional penetration testing methods often place the heads on conveyors for transmission and testing. However, since the heads are stationary on the conveyor belt, local areas are easily obscured, making it difficult to obtain comprehensive and rapid non-destructive penetration testing in these obscured areas. This directly affects the quality inspection effect and efficiency of the heads.

[0005] To this end, the present invention provides a head processing and feeding device. Summary of the Invention

[0015] Preferably, a connecting frame is fixedly connected to the outer wall of one of the fixing frames; and a detector is fixedly connected to the bottom end of the connecting frame.

[0016] Preferably, a friction pad is fixedly connected to the outer wall of the annular belt; the friction pad is made of rubber.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The head processing and feeding device described in the present invention transmits butterfly heads for non-destructive testing by arranging a roller conveyor instead of a traditional belt conveyor, and relies on fixed clamping and conveying the head for testing, which can avoid shaking caused by vibration of the traditional conveyor belt, ensure uniform coverage of the penetrant, reduce detection blind spots caused by movement, and prevent deformation and surface damage caused by friction of the conveyor belt with the head; at the same time, clamping and conveying can realize multi-angle rotation of the head, which is convenient for the penetrant to fully penetrate complex curved surfaces and improve the detection rate of cracks and pores.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1 to 4 、 Figure 7As shown, a head processing and feeding device described in an embodiment of the present invention includes a conveyor 1; each roller of the conveyor 1 is fixedly connected to a fixed seat 11; one side of the fixed seat 11 is fixedly connected to a No. 1 side frame 12; the top of the No. 1 side frame 12 is fixedly connected to a No. 2 side frame 14 on the fixed seat 11 and on the side opposite to the No. 1 side frame 12; the top of the No. 2 side frame 14 is slidably connected to a sliding rod 15; the bottom end of the sliding rod 15 is fixedly connected to an electric slider 16, and the electric slider 16 is slidably connected to the No. 2 side frame 14; when dealing with the task of non-destructive penetration testing of large quantities of heads, the original belt conveyor 1 is changed to a roller conveyor 1, and each roller of the conveyor 1 is equipped with a clamping assembly for fixing butterfly-shaped, elliptical or hemispherical heads. Taking the inspection of butterfly heads as an example, the butterfly heads are automatically loaded onto the fixed seat 11 between the No. 1 side frame 12 and the No. 2 side frame 14 through a robot. When the butterfly head is in the process of being transported to the inspection area by the conveyor 1, the clamped butterfly head is sprayed with penetrant, and then the butterfly head is sprayed with water to rinse the butterfly head to make the defects appear. Finally, the butterfly head with defects is subjected to non-destructive penetration testing by the testing equipment, and can be packaged after passing the testing. The roller conveyor 1 replaces the traditional belt conveyor 1 for conveying the butterfly head for non-destructive testing. By relying on the fixed clamping conveying and feeding testing of the head, the shaking caused by the vibration of the traditional conveyor belt can be avoided, and the penetrant can be evenly covered, thereby reducing the detection blind spot caused by movement, and preventing the deformation and surface damage caused by the friction of the conveyor belt.

[0031] At the same time, the clamping conveyor can realize multi-angle rotation of the head, which facilitates the penetrant to fully penetrate the complex curved surface and improve the detection rate of cracks and pores. The conveyor belt can usually only move horizontally, which makes it difficult to optimize the direction of the inspection surface;

[0032] In addition, clamping and conveying can avoid contact between the head and the conveyor belt, prevent oil and dirt from adhering, and reduce the burden of pre-treatment cleaning. The conveyor belt may also have residual penetrants, and clamping and conveying can reduce the risk of cross contamination.

[0033] The inner walls of the fixed rod 13 and the sliding rod 15 are both rotatably connected to the extension rod 2; the extension rod 2 is fixedly connected to a block 21 at one end near the fixed seat 11; the inner wall of the block 21 is slidably connected to an extrusion block 22 by an elastic member; when the butterfly head is clamped and loaded for non-destructive penetration testing, the manipulator is used to first move one side of the butterfly head to fit the material to the side of the block 21 above the fixed rod 13, and the extension rod 2 connects the fixed rod 13 with the block 21. At this time, the electric slider 16 drives the extension rod 2 on the sliding rod 15 to slide close to the other side of the head, so that the two blocks 21 are clamped in the center of the butterfly head. As the electric slider 16 continues to slide, the stability of the head clamping is improved. At the same time, the two extrusion blocks 22 are tightly fitted on both sides of the head. As the sliding rod 15 slides close to the head, the extrusion blocks 22 squeeze the elastic member and contract with force, so that the two extrusion blocks 22 are tightly fitted on both sides of the head to clamp the head, thereby improving the effect of clamping the head.

[0034] The top and bottom surfaces of the block 21 are rotatably connected to the rotating shaft 3 through a torsion spring; the outer wall of the rotating shaft 3 is fixedly connected to a pressure plate 31; when the butterfly head is clamped and loaded, the two blocks 21 are relied upon to clamp the two sides of the head. Due to the special shape of the head, it is easy to slip during the loading process. The two rotating shafts 3 are respectively installed on the top and bottom surfaces of the block 21 through torsion springs. When the head is clamped between the two blocks 21, multiple pressure plates 31 can automatically fit the special shape of the butterfly head during the extrusion process. For example, some pressure plates 31 can fit the inner concave surface of the butterfly head, and other part of the pressure plates 31 can fit the convex surface of the butterfly head, thereby improving the stability of the material feeding on the head.

[0035] The outer wall of the pressure plate 31 is fixed with a sponge block 4; the sponge block 4 is located on the side of the pressure plate 31 close to the fixed seat 11; when multiple pressure plates 31 are clamped on both sides of the butterfly head, the pressure plate 31 is likely to scratch the surface of the butterfly head. The sponge block 4 is fixed on the side of the pressure plate 31 that is in contact with the head. The sponge block 4 can protect the butterfly head during the clamping, conveying and loading process, reducing the situation where the pressure plate 31 scratches the head due to excessive clamping. At the same time, the sponge block 4 can absorb the penetrant, so that the area clamped by the pressure plate 31 can also be adhered with the penetrant for easy detection.

[0036] like Figure 1 、 Figure 2 and Figure 5As shown, the end of the extension rod 2 on the fixed rod 13 away from the fixed seat 11 is fixedly connected to a friction roller 5; four fixed plates 51 are fixedly connected to the conveyor 1, and the four fixed plates 51 are arranged in pairs, and a short rod is rotatably connected between the two opposite fixed plates 51; an annular belt 52 is sleeved between the two short rods; a servo motor 53 is fixedly connected to the outer wall of one of the fixed plates 51, and the output end of the servo motor 53 passes through the fixed plate 51 and is fixed to a short rod; when the clamped head is conveyed and loaded for inspection, the surface of the clamped and conveyed head is sprayed with penetrant, and the friction roller 5 is used to fit the surface of the annular belt 52. As the output end of the servo motor 53 drives one of the short rods on the two fixed plates 51 to rotate, the other short rod connected to the annular belt 52 is synchronously driven to rotate, so that the annular belt 52 rubs against the friction roller 5 during its rotation, and the friction roller 5 then drives the clamped head to rotate. The nozzle is fixed on the side of the head to continuously and evenly spray the penetrant, thereby improving the uniform effect of spraying the penetrant on the head.

[0037] Furthermore, the conveyor 1 can be stopped, and the endless belt 52 can be activated to rotate so that the head can rotate in situ, so as to facilitate the comprehensive inspection of the head by the inspection equipment;

[0038] At the same time, the output end of the servo motor 53 can also drive the annular belt 52 to rotate in both directions, thereby synchronously driving the clamped head to rotate in both directions. The curvature of the spherical surface and the transition zone of the butterfly head varies greatly. One-way rotation may cause the penetrant to accumulate on the concave surface and insufficient coverage of the convex surface. Operation: forward rotation allows the penetrant to flow into the low place, and reverse rotation ensures that the high place can also be infiltrated;

[0039] The penetrant will flow downward due to the influence of gravity. If the defect opening is facing downward during unidirectional rotation, it may not be filled. Operation: Pause after forward rotation to allow the penetrant to initially penetrate the defect, and reverse rotation to change the direction of the defect to ensure that all open transverse cracks in all directions are penetrated. Unidirectional rotation may only show cracks in a single direction, while bidirectional rotation can expose multi-directional defects.

[0040] like Figures 1 to 4 、 Figure 6 、 Figure 7As shown, the outer wall of the fixing seat 11 is fixed with a support plate 6; the top of the support plate 6 is fixed with a liquid injection pipe 61; the two sides of the support plate 6 are respectively fixed with a liquid injection pipe 61 and a No. 1 nozzle 62, and the liquid injection pipe 61 and the No. 1 nozzle 62 are connected to the liquid injection pipe 61 through a three-way pipe; when the butterfly head for clamping and loading is sprayed with a penetrant to reveal defects and water cleaning, the support plate 6 is fixed to one side of the fixing seat 11 as a supporting structure. Taking the penetrant as an example, the penetrant is sprayed on the butterfly head for clamping and loading. The agent tube is inserted into the injection tube 61 and the penetrant is pumped into the penetrant. Then the penetrant is passed into the No. 1 nozzle 62 and the No. 2 nozzle 63 along the three-way pipe. The No. 1 nozzle 62 and the No. 2 nozzle 63 are atomized and sprayed on the surfaces of both sides of the butterfly head. As the conveyor 1 stops conveying, the friction roller 5 is driven to rotate by the annular belt 52 to achieve uniform spraying of the penetrant on the clamped head. The same operation is performed for water cleaning. Just replace the penetrant with water to achieve the effect of rotating and spraying the clamped head.

[0041] The spray holes of the No. 1 nozzle 62 and the No. 2 nozzle 63 are respectively arranged on one side close to the injection pipe 61; the cross-sectional shapes of the No. 1 nozzle 62 and the No. 2 nozzle 63 are both curved arc-shaped; relying on the curved arc-shaped cross-sectional shapes of the No. 1 nozzle 62 and the No. 2 nozzle 63, the spray holes of the No. 1 nozzle 62 and the No. 2 nozzle 63 can fit the special surface of the butterfly head, thereby improving the uniformity of spraying on the butterfly head.

[0042] like Figures 1 to 4 、 Figure 7 As shown, the outer wall of the conveyor 1 is fixed with two fixing frames 7; an electric cylinder 71 is fixed on the fixing frame 7; the output end of the electric cylinder 71 is fixed with a plug-in tube 72, and the plug-in tube 72 corresponds to the injection tube 61; a storage box 73 is fixed at a right angle to the outer wall of the fixing frame 7, and a water pump is fixed inside the storage box 73; a guide tube 74 is fixed at the output end of the water pump, and the guide tube 74 is connected to the plug-in tube 72; when the penetrant or water is injected into the injection tube 61, the two fixing frames 7 are respectively fixed to the middle and At the rear end, the middle storage box 73 is filled with penetrant, and the rear end storage box 73 is filled with water for cleaning the penetrant on the head. When the injection pipe 61 on one side of the head is transported to the bottom of the plug-in pipe 72 by the conveyor 1, the output end of the electric cylinder 71 drives the plug-in pipe 72 to slide down and insert into the injection pipe 61. At this time, the water pump in the storage box 73 extracts the liquid and sends it into the plug-in pipe 72 through the guide pipe 74. The liquid is sent to the No. 1 nozzle 62 and the No. 2 nozzle 63 through the injection pipe 61 for atomization spraying, which plays the role of transporting the penetrant and water respectively.

[0043] A connecting frame 8 is fixedly connected to the outer wall of one of the fixing frames 7; a detector 81 is fixedly connected to the bottom end of the connecting frame 8; when the head is sprayed with penetrant and then cleaned with water, the connecting frame 8 fixed on the rear end fixing frame 7 supports the detector 81. As the annular belt 52 continues to drive the friction roller 5 to connect the clamped head to rotate, the detector 81 comprehensively detects the rotating head, mainly detecting surface cracks, stress cracks, fatigue cracks, pores, inclusions and folds and other opening defects, thereby playing a role in non-destructive penetration detection of the head.

[0044] like Figure 1 、 Figure 2 and Figure 5 As shown, the outer wall of the annular belt 52 is fixed with a friction pad 9; the material of the friction pad 9 is rubber; when the head for clamping and feeding is rotated, the output end of the servo motor 53 drives the annular belt 52 to rub the friction roller 5 to rotate, so that the head connected to the friction roller 5 rotates synchronously, and multiple friction pads 9 are fixed on the surface of the annular belt 52. Multiple friction pads 9 can increase the friction of the annular belt 52 on the friction roller 5, thereby improving the stability of the rotation of the clamped head.

[0045] Working process: When dealing with the task of non-destructive penetration testing of large quantities of heads, the original belt conveyor 1 is changed to a roller conveyor 1. Each roller of the conveyor 1 is equipped with a clamping component for fixing butterfly, elliptical or hemispherical heads. Taking the inspection of butterfly heads as an example, the butterfly heads are automatically loaded onto the fixed seat 11 between the No. 1 side frame 12 and the No. 2 side frame 14 through the robot. At this time, one side of the concave part of the butterfly head is fitted with one end of the fixed rod 13, and then the electric slider 16 drives the sliding rod 15 to slide on the No. 2 side frame 14 until one end of the sliding rod 15 is fitted with the other side of the butterfly head. The fixed rod 13 cooperates with the sliding rod 15 to clamp and fix the butterfly head, exposing more parts of the butterfly head. As the conveyor 1 clamps the butterfly head In the process of conveying the butterfly head to the inspection area, the clamped butterfly head is sprayed with penetrant, and then the butterfly head is sprayed with water to make the defects visible. Finally, the butterfly head with defects is subjected to non-destructive penetration inspection by the inspection equipment. After passing the inspection, it can be packaged. The roller conveyor 1 replaces the traditional belt conveyor 1 to transport the butterfly head for non-destructive inspection. Relying on the fixed clamping and conveying feeding inspection of the head, it can avoid the shaking caused by the vibration of the traditional conveyor belt, and ensure the uniform coverage of the penetrant, reduce the inspection blind area caused by movement, and prevent the deformation and surface damage caused by the friction of the conveyor belt to the head; at the same time, the clamping conveying can realize the multi-angle rotation of the head, which is convenient for the penetrant to fully penetrate the complex curved surface and improve the detection rate of cracks and pores. The conveyor belt can usually only be horizontal Movement makes it difficult to optimize the direction of the inspection surface; and clamping and conveying can avoid contact between the head and the conveyor belt, prevent oil and dirt from adhering, and reduce the burden of pre-treatment cleaning. The conveyor belt may also have residual penetrants, and the risk of cross-contamination can be reduced by clamping and conveying; when the butterfly head is clamped and loaded for non-destructive penetration testing, a manipulator is used to first fit one side of the butterfly head and the loading material to the side of the block 21 above the fixed rod 13, and the extension rod 2 connects the fixed rod 13 with the block 21. At this time, the electric slider 16 drives the extension rod 2 on the sliding rod 15 to slide close to the other side of the head, so that the two blocks 21 are clamped in the center of the butterfly head. As the electric slider 16 continues to slide, the stability of the head clamping is improved, and at the same time, the two extrusion blocks 22 are tightly fitted on both sides of the head. As the sliding rod 15 slides closer to the head, the extrusion block 22 squeezes the elastic member and contracts to bear the force, so that the two extrusion blocks 22 are tightly fitted to the two sides of the head to clamp the material, thereby improving the clamping effect of the head; when the butterfly head is clamped and fed, the two blocks 21 are relied on to clamp the two sides of the head. Due to the special shape of the head, it is easy to slip during the feeding process. The two rotating shafts 3 are respectively installed on the top and bottom surfaces of the blocks 21 through torsion springs. When the head is clamped between the two blocks 21, the multiple pressure plates 31 can automatically adapt to the special shape of the butterfly head during the extrusion process. For example, some pressure plates 31 can fit the inner concave surface of the butterfly head, and other parts of the pressure plates 31 can fit the convex surface of the butterfly head, thereby improving the stability of the material feeding on the head;When multiple pressing plates 31 are attached to both sides of the butterfly head for clamping, the pressing plates 31 are prone to scratching the surface of the butterfly head. A sponge block 4 is fixed to the side of the pressing plate 31 that is attached to the head. The sponge block 4 can protect the butterfly head during the clamping, conveying and loading process, thereby reducing the situation where the pressing plate 31 scratches the head due to excessive clamping. At the same time, the sponge block 4 can absorb the penetrant, so that the area clamped by the pressing plate 31 can also be adhered to the penetrant for easy detection.

[0046] During the process of conveying and testing the clamped head, the penetrant is sprayed on the surface of the clamped head, and the friction roller 5 is used to fit the surface of the annular belt 52. As the output end of the servo motor 53 drives a short rod on the two fixed plates 51 to rotate, the other short rod connected to the annular belt 52 is synchronously driven to rotate, so that the annular belt 52 rubs the friction roller 5 during the rotation process, and the friction roller 5 drives the clamped head to rotate. The nozzle is fixed on the side of the head to continuously and evenly spray the penetrant, thereby improving the uniform effect of spraying the penetrant on the head; and the conveyor 1 can be stopped, and the annular belt 52 can be enabled to rotate to make the head rotate in place, so that the detection equipment can perform a comprehensive detection of the head; at the same time The output end of the servo motor 53 can also drive the annular belt 52 to rotate in both forward and reverse directions, thereby synchronously driving the clamped head to rotate in both directions. The curvature of the spherical surface and the transition zone of the butterfly head varies greatly. One-way rotation may cause the penetrant to accumulate on the concave surface and insufficient coverage of the convex surface. Operation: Forward rotation allows the penetrant to flow into the low place, and reverse rotation ensures that the high place can also be infiltrated; the penetrant will flow downward under the influence of gravity. If the defect opening is facing downward during one-way rotation, it may not be filled. Operation: Pause after forward rotation to allow the penetrant to initially penetrate the defect, and reverse rotation changes the direction of the defect to ensure that all open transverse cracks in all directions are penetrated. One-way rotation may only show cracks in a single direction, and two-way rotation can expose multi-directional defects.

[0047] When spraying penetrant on the butterfly head clamping the material to reveal defects and water cleaning, the support plate 6 is fixed on one side of the fixed seat 11 as a supporting structure. Taking the penetrant as an example, the penetrant tube is inserted into the injection pipe 61 and pumped into the penetrant. Then the penetrant is passed into the No. 1 nozzle 62 and the No. 2 nozzle 63 along the three-way pipe. The No. 1 nozzle 62 and the No. 2 nozzle 63 spray the surfaces of both sides of the butterfly head in an atomized manner. As the conveyor 1 stops conveying, the friction roller 5 is driven to rotate by the annular belt 52 to achieve The penetrant is sprayed evenly on the clamped head by rotation, and the water cleaning is done in the same way, and the penetrant is replaced with water, which plays the role of rotating and spraying the clamped head; relying on the curved cross-sectional shape of the No. 1 nozzle 62 and the No. 2 nozzle 63, the spray holes of the No. 1 nozzle 62 and the No. 2 nozzle 63 can fit the special surface of the butterfly head, thereby improving the uniformity of spraying on the butterfly head; when the penetrant or water is injected into the injection pipe 61, the two fixing frames 7 are respectively fixed in the middle of the conveyor 1 The storage box 73 at the front and rear ends is filled with penetrant, and the storage box 73 at the rear end is filled with water for cleaning the penetrant on the head. When the injection pipe 61 on one side of the head is transported to the bottom of the plug-in pipe 72 by the conveyor 1, the output end of the electric cylinder 71 drives the plug-in pipe 72 to slide down and insert into the injection pipe 61. At this time, the water pump in the storage box 73 extracts liquid and sends it into the plug-in pipe 72 through the guide pipe 74. The liquid is sent to the first nozzle 62 and the second nozzle 63 for atomization spraying through the injection pipe 61, which plays the role of transporting the penetrant and water respectively; when the head is sprayed with penetrant and cleaned with water, the connecting frame 8 fixed on the rear end fixing frame 7 supports the detector 81. As the annular belt 52 continues to drive the friction roller 5 to connect the clamped head to rotate, the detector 81 comprehensively detects the rotating head, mainly detecting surface cracks, stress cracks, fatigue cracks, pores, inclusions and folding and other opening defects, which plays the role of non-destructive penetration detection of the head;

[0048] When the head for clamping and feeding is rotated, the output end of the servo motor 53 drives the annular belt 52 to rub the friction roller 5 to rotate, so that the head connected to the friction roller 5 rotates synchronously. Multiple friction pads 9 are fixed on the surface of the annular belt 52. The multiple friction pads 9 can increase the friction of the annular belt 52 on the friction roller 5, thereby improving the stability of the rotation of the clamped head.
