Description

Technical Field

[0001] This utility model relates to the field of plasma spraying technology for flange castings, and more specifically, to a plasma spraying device for corrosion-resistant flange castings. Background Technology

[0002] Plasma spraying uses a DC arc to ionize working gases such as argon and nitrogen to form a high-temperature plasma jet. Ceramic, metal, or alloy powders are fed into the jet to melt or partially melt, and then sprayed onto the flange surface at a high speed of 300-500 m / s to form a dense coating. The coating can increase the hardness and corrosion resistance of the flange and reduce the risk of leakage at the flange mating surface due to friction or liquid flow.

[0003] Existing plasma spraying equipment for corrosion-resistant flange castings typically employs two clamping methods: one is to directly fix the inner wall of the flange, and the other is to use jaws to clamp both sides of the flange. However, both methods have significant drawbacks: the contact surface between the clamping components and the flange obstructs the spraying area, preventing full coverage spraying. Operators must repeatedly release the clamps, adjust the flange position, and re-spray, reducing spraying efficiency. This process defect directly affects production efficiency and coating uniformity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a plasma spraying device for corrosion-resistant flange castings. This device, through a positioning and clamping assembly, first clamps the inner wall of the flange casting. After the outer surface of the flange casting is sprayed, the outer wall of the corrosion-resistant flange casting is clamped by the push of lead screw A, thereby spraying the inner wall of the corrosion-resistant flange casting. This avoids obstruction of the corrosion-resistant flange casting due to the contact points between the clamping components and the casting during clamping, which would hinder comprehensive spraying. Furthermore, this equipment eliminates the need for repeated manual adjustments to the position of the corrosion-resistant flange casting during spraying, thus reducing the workload of workers and improving the efficiency of flange casting spraying.

[0005] The technical solution of this application is as follows:

[0006] A plasma spraying device for corrosion-resistant flange castings includes a fixed base, a control console on the front side of the fixed base, a positioning and clamping assembly on the upper part of the fixed base, and spraying assemblies on both sides of the fixed base. The spraying assemblies and the positioning and clamping assembly cooperate with each other. The positioning and clamping assembly includes an electric slide block, which is located on the upper part of the fixed base. The surface of the electric slide block is provided with mutually adapted sliding seats, and the sliding seats and the electric slide block cooperate with each other to form a sliding mechanism. A support frame is fixedly connected to the middle of the upper part of the sliding seats.

[0007] Compared with the prior art, this utility model, by setting a positioning clamping component, allows the inner wall of the flange casting to be clamped first. After the outer surface of the flange casting is sprayed, the outer wall of the corrosion-resistant flange casting can be clamped under the push of the lead screw A, thereby spraying the inner wall of the corrosion-resistant flange casting. This avoids the obstruction of the corrosion-resistant flange casting by the contact part between the clamping component and the corrosion-resistant flange casting during clamping, which would make it difficult to spray the entire casting. In addition, the device of this utility model does not require manual adjustment of the position of the corrosion-resistant flange casting multiple times during spraying, thereby reducing the workload of the workers and improving the efficiency of spraying flange castings.

[0008] As an optimization, a rotating chuck body is provided in the middle of the support frame, and two drive electric cylinders A are provided on the support frame on both sides of the rotating chuck body. The output shaft of the drive electric cylinder A passes through the support frame, and a protective box is fixedly connected to the output shaft of the drive electric cylinder A. A motor A is fixedly connected to the opposite side of each of the protective boxes, and the output shaft of the motor A passes through the protective box. A drive gear A is fixedly connected to the output shaft of the motor A, and a driven gear A is meshed with the upper part of the drive gear A to facilitate the adjustment of the position of the flange casting.

[0009] As an optimization, the driven gear A has a threaded groove in its inner cavity, and a lead screw A is threadedly connected to the inner cavity of the threaded groove. The thread of the lead screw A passes through both sides of the protective box, and a positioning piston is movably connected to the opposite side of each lead screw A. The piston can be used to softly clamp the flange casting.

[0010] As an optimization, the spraying assembly includes a U-shaped frame, which is fixedly connected to a fixed base. A limiting groove is formed on the upper part of the U-shaped frame. A lead screw B is movably connected to the other side of the inner cavity of the limiting groove through a rotating joint. A moving block is threadedly connected to the surface of the lead screw B. An L-shaped support plate is fixedly connected to the upper part of the moving block.

[0011] As an optimization, a drive cylinder B is fixedly connected to the upper part of the L-shaped support plate. The output shaft of the drive cylinder B passes through the L-shaped support plate. A guide plate is fixedly connected to the front side of the L-shaped support plate. A spraying mechanism body is fixedly connected to the output shaft of the drive cylinder B. A guide groove is provided on the rear side of the spraying mechanism body. The guide groove and the guide plate cooperate with each other to limit the position of the lead screw B.

[0012] As an optimization, one side of the lead screw B passes through the U-shaped frame, and a driven gear B is fixedly connected to one side of the lead screw B. A drive gear B is meshed with the lower part of the driven gear B. A dust cover is fixedly connected to one side of the U-shaped frame, and a motor B is fixedly connected to one side of the dust cover. The output shaft of the motor B passes through the dust cover and is fixedly connected to the drive gear B, which facilitates the protection of the driven gear B and the drive gear B.

[0020] The present application will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present application.

[0021] Example (see) Figures 1-6 ):

[0022] The plasma spraying device for corrosion-resistant flange castings includes a fixed base 1, a control console 2 is provided on the front side of the fixed base 1, a positioning and clamping assembly is provided on the upper part of the fixed base 1, and spraying assemblies are provided on both sides of the fixed base 1. The spraying assemblies and the positioning and clamping assemblies cooperate with each other.

[0023] In this embodiment, the positioning and clamping assembly includes an electric slide 3, which is disposed on the upper part of the fixed base 1. The surface of the electric slide 3 is provided with a sliding seat 4 that is adapted to each other, and the sliding seat 4 and the electric slide 3 cooperate with each other to form a sliding mechanism. A support frame 5 is fixedly connected to the middle part of the upper part of the sliding seat 4.

[0024] In this embodiment, a rotating claw body 6 is provided in the middle of the support frame 5. Two drive electric cylinders A7 are provided on the support frame 5 on both sides of the rotating claw body 6. The output shaft of the drive electric cylinder A7 passes through the support frame 5. A protective box 8 is fixedly connected to the output shaft of the drive electric cylinder A7. A motor A9 is fixedly connected to the opposite side of each protective box 8. The output shaft of the motor A9 passes through the protective box 8. A drive gear A10 is fixedly connected to the output shaft of the motor A9. A driven gear A11 is meshed with the upper part of the drive gear A10.

[0025] In this embodiment, the driven gear A11 has a threaded groove in its inner cavity, and a lead screw A12 is threadedly connected to the inner cavity of the threaded groove. The thread of the lead screw A12 passes through both sides of the protective box 8. A positioning piston 13 is movably connected to the opposite side of each lead screw A12. When it is necessary to spray the flange casting, the inner ring of the flange casting contacts the rotating jaw body 6. The rotating jaw is a circular jaw in the prior art, driven by a servo motor. The jaw of the rotating jaw body 6 moves to squeeze the inner wall of the flange casting, thus fixing the flange casting. The electric slide 3 is activated to drive the slide 4 to move horizontally. Then, the spraying assembly sprays the edge of the flange casting, and the rotating jaw body 6 drives the flange casting to rotate, so that the plasma is evenly sprayed on the side of the flange casting. After the side spraying is completed, the drive cylinder A7 is activated, and the output shaft of the drive cylinder A7 drives the protective box 8 to move. The drive cylinder A9 moves to the position corresponding to the flange casting and drives the drive gear A10 to rotate via the output shaft of the drive gear A10. When the drive gear A10 rotates, it drives the gear A to rotate, and the driven gear A11 drives the screw threadedly connected to the inner cavity to rotate and move. A limit wheel is provided on the side of the gear A, and a fixing rod is provided inside the limit wheel through a bearing. The fixing rod is fixed to the inner wall of the protective box 8, thereby achieving the effect of limiting the driven gear A11. When the screw A12 rotates and moves, it can push the positioning piston 13 to move towards the flange casting and fix the flange casting. After the fixing is completed, it contacts the rotating claw body 6 to limit the flange casting, and the output of the drive cylinder A7 pushes the protective box 8 to drive the screw A12 to move. The screw A12 drives the flange casting to move to the side away from the rotating claw body 6, and then the spraying assembly sprays plasma onto the surface of the flange casting.

[0026] In this embodiment, the spraying assembly includes a U-shaped frame 14, which is fixedly connected to the fixed base 1. A limiting groove is provided on the upper part of the U-shaped frame 14. A lead screw B15 is movably connected to the other side of the inner cavity of the limiting groove through a rotating joint. A moving block 16 is threadedly connected to the surface of the lead screw B15. An L-shaped support plate 17 is fixedly connected to the upper part of the moving block 16.

[0027] In this embodiment, a drive cylinder B18 is fixedly connected to the upper part of the L-shaped support plate 17. The output shaft of the drive cylinder B18 passes through the L-shaped support plate 17. A guide plate 19 is fixedly connected to the front side of the L-shaped support plate 17. A spraying mechanism body 20 is fixedly connected to the output shaft of the drive cylinder B18. A guide groove is provided on the rear side of the spraying mechanism body 20. The guide groove cooperates with the guide plate 19.

[0028] In this embodiment, one side of the lead screw B15 passes through the U-shaped frame 14, and a driven gear B21 is fixedly connected to one side of the lead screw B15. A drive gear B22 is meshed with the lower part of the driven gear B21. A dust cover 23 is fixedly connected to one side of the U-shaped frame 14, and a motor B24 is fixedly connected to one side of the dust cover 23. The output shaft of the motor B24 passes through the dust cover 23 and is fixedly connected to the drive gear B22. When it is necessary to spray the flange casting, the spraying mechanism body 20 is connected to the external spraying part. When the height needs to be adjusted when spraying the flange casting, the drive cylinder B18 can be started. The output shaft of the drive cylinder B18 pushes the spraying mechanism body 20 to move downward along the direction limited by the guide plate 19, thereby adjusting the height of the spraying mechanism body 20. When it is necessary to move the spraying mechanism body 20 left or right, the motor B24 can be started. The output shaft of the motor B24 drives the drive gear B22 to rotate, and the drive gear B22 drives the driven gear B21 to rotate. When the driven gear B21 rotates, it drives the internally fixed lead screw B15 to rotate, and the lead screw B15 drives the surface threaded moving block 16 to move. The moving block 16 then drives the L-shaped support plate 17 to move, and the L-shaped support plate 17 drives the spraying mechanism body 20 to move.
