Description

Technical Field

[0001] This utility model relates to the field of valve ball spraying technology, and in particular to a valve ball thermal spraying equipment. Background Technology

[0002] Currently, the utility model patent with publication number CN210753532U discloses a thermal spraying device for uniformly spraying the inner ball of a valve. This technical solution uses an electric motor to drive the valve ball to rotate at a uniform speed, thereby achieving uniform spraying of the surface of the valve ball by the thermal spraying device. However, this technical solution has certain inconveniences in terms of material loading and unloading. Since the fixing devices are all set inside the outer shell, each time the staff loads or unloads the valve ball, they need to enter the outer shell by hand. However, after thermal spraying, the surface temperature of the valve ball is high, and the thermal spraying device is also relatively close to the fixing position of the valve ball, so there are certain safety hazards. Utility Model Content

A third shielding wall is horizontally mounted between the first and second shielding walls, and a passage is provided on the third shielding wall. A thermal spraying mechanism is mounted on the first shielding wall, with the spraying direction of the thermal spraying mechanism pointing towards the second shielding wall. A ball internal channel fixing mechanism is mounted between the thermal spraying mechanism and the second shielding wall on the first frame. The ball internal channel fixing mechanism includes an operating frame and two clamping blocks slidably mounted on the operating frame. The operating frame is equipped with a spacing adjustment mechanism for moving the two clamping blocks closer or further apart.

[0013] 2. The first motor and lead screw can be used to move the clamping blocks away from each other until they support the side wall of the valve ball's internal channel, which is beneficial for the clamping blocks to drive the valve ball to rise and fall without hindering the thermal spraying mechanism from spraying the surface of the valve ball.

[0023] Example:

[0024] like Figures 1 to 4As shown, this utility model discloses a valve ball thermal spraying device, including a base 1, on which a first frame 11 is provided. A first shielding wall 111 and a second shielding wall 112 are vertically provided on the first frame 11. The first shielding wall 111 and the second shielding wall 112 are both fixedly provided on the first frame 11 and are arranged opposite to each other. At the same time, a third shielding wall 113 is arranged horizontally between the first shielding wall 111 and the second shielding wall 112 on the first frame 11. The third shielding wall 113 has a passage opening 114.

[0025] The first frame 11 is equipped with a thermal spraying mechanism 115 on the first shielding wall 111. The spraying direction of the thermal spraying mechanism 115 is directed towards the second shielding wall 112. At the same time, the first frame 11 is equipped with a spherical internal channel fixing mechanism between the thermal spraying mechanism 115 and the second shielding wall 112. The spherical internal channel fixing mechanism includes an operating frame 116 and two clamping blocks 25 slidably set on the operating frame 116. The operating frame 116 is equipped with a spacing adjustment mechanism for moving the two clamping blocks 25 away from or closer to each other. The first frame 11 is equipped with a lifting mechanism for moving the clamping blocks 25 up and down between the passage openings 114 and a rotating mechanism for rotating the operating frame 116.

[0026] The spacing adjustment mechanism specifically includes a lead screw 24 rotatably mounted on the operating frame 116 and a first motor 23 fixedly mounted on the operating frame 116. In this structure, the output end of the first motor 23 is fixedly connected to the lead screw 24. The lead screw 24 is a bidirectional lead screw 24. The clamping block 25 is connected to the lead screw 24 through a threaded engagement, and the clamping block 25 is set to slide only on the operating frame 116.

[0027] The lifting mechanism specifically includes a cylinder 21 fixedly mounted on the first frame 11. The cylinder 21 includes a first piston rod 22, which extends downward and its lower end is connected to the operating frame 116.

[0028] The first piston rod 22 is rotatably connected to the operating frame 116. The rotating mechanism specifically includes a first gear 27, a second gear 28, and a second motor 26. The first gear 27 is sleeved on the outside of the first piston rod 22 and is fixedly connected to the first piston rod 22. The second gear 28 is rotatably connected to the operating frame 116 and meshes with the first gear 27. The second motor 26 is fixedly mounted on the operating frame 116 and its output end is connected to the second gear 28.

[0029] A second frame 12 is provided on the side of the base 1 next to the first frame 11. A conveyor 31 is provided on the second frame 12. A spherical feeding and unloading device is provided between the conveyor 31 and the first frame 11.

[0030] The spherical feeding and unloading device includes a rotary cylinder 32 and a swing rod 34. The rotary cylinder 32 is fixedly mounted on the second frame 12, and the swing rod 34 is laterally positioned between the second frame 12 and the third shielding wall 113. In this structure, the rotary cylinder 32 includes a second piston rod 33. One end of the swing rod 34 is fixedly connected to the second piston rod 33, and the other end is fixedly mounted with a pneumatic finger 35. The pneumatic finger 35 swings around the second piston rod 33 as the center, driven by the rotary cylinder 32. The movement path of the pneumatic finger 35 passes through the conveyor table 31 and the through port 114.

[0031] The second frame 12 has a material discharge port 36 on the side of the conveyor 31 near the rotary cylinder 32, and a material collection basket 37 is provided below the material discharge port 36.

[0032] Combination Figure 1 and Figure 2 The working principle of this structure is as follows: The valve ball is placed on the conveyor 31. When the conveyor 31 transports the valve ball to one end near the rotary cylinder 32, the pneumatic finger 35 clamps the outer wall of the valve ball. Then, the rotary cylinder 32 drives the swing rod 34 to swing, causing the pneumatic finger 35 to move the valve ball below the through hole. At this time, the cylinder 21 drives the operating frame 116 downwards, causing the clamping block 25 on the operating frame 116 to move downwards through the through hole 114 until the clamping block 25 extends into the channel of the valve ball. At this point, the first motor 23 drives the clamping blocks 25 to move away from each other, causing the clamping blocks 25 to abut against the channel of the valve ball. The pneumatic finger 35 releases the valve ball, and the cylinder 21... The valve ball is moved upwards and into the spraying range of the thermal spraying mechanism 115. The thermal spraying mechanism 115 then begins to spray the valve ball. During the spraying process, the second motor 26 starts to work, causing the operating frame 116 to rotate around the axis of the first piston rod 22 under the meshing transmission of the first gear 27 and the second gear 28. This achieves uniform spraying of the valve ball surface by the thermal spraying mechanism 115. After the spraying work is completed, the cylinder 21 drives the operating frame 116 to move downwards again, causing the pneumatic finger 35 to grip the valve ball again. The pneumatic finger 35 then places the valve ball back onto the conveyor table 31. The conveyor table 31 moves the valve ball along the original route, causing the valve ball to fall into the receiving basket 37.
