Description

Technical Field

[0001] This utility model relates to the field of ball processing technology, and in particular to an automated machine for polishing ball valves. Background Technology

[0002] Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media. They require only a 90-degree rotation and a very small torque to achieve a tight seal. In my country, ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, power, municipal engineering, and steel, playing a crucial role in the national economy. The precision of the ball's machining, as the opening and closing element of the ball valve, is critical to its quality.

[0003] The sphere processing process requires polishing, and existing sphere processing equipment such as... Figure 6 As shown, the assembly includes a worktable 1, a sliding plate 2, a first polishing assembly 3, a second polishing assembly 4, and a ball support 5. The sliding plate 2 is slidably connected to the worktable 1. The first polishing assembly 3 includes a first drive assembly 31 and a first polishing wheel 32. The second polishing assembly 4 includes a second drive assembly 41 and a second polishing wheel 42. Both the first drive assembly 31 and the second drive assembly 41 include a drive motor 311, a first support base 312, a second support base 313, a first pulley 314, a second pulley 315, and a belt 316. The first pulley 314 is rotatably connected to the first support base 312 and is fixedly connected to the output shaft of the drive motor 311. The second pulley 315 is rotatably connected to the second support base 312. On the 13, belt 316 meshes with first pulley 314 and second pulley 315. First drive assembly 31 is disposed on worktable 1, and second drive assembly 41 is disposed on sliding plate 2. First polishing wheel 32 is fixedly connected to the shaft of second pulley 315 of first drive assembly 31, and second polishing wheel 42 is fixedly connected to the shaft of second pulley 315 of second drive assembly 41. Ball support 5 includes support cylinder 56 and support shaft 52. Cylinder body of support cylinder 56 is fixedly connected to worktable 1, and support shaft 52 is fixedly connected to piston rod of support cylinder 56. Support shaft 52 is a stepped shaft, and the diameter of the end of support shaft 52 away from support cylinder 56 is smaller than the diameter of the end of support shaft 52 close to support cylinder 56. When processing the sphere, the piston rod of the support cylinder 56 moves, pushing the support shaft 52 vertically upward. The operator places the sphere on the support shaft 52. The piston rod of the support cylinder 56 returns to its original position, moving the sphere between the first polishing wheel 32 and the second polishing wheel 42. The operator pushes the sliding plate 2, causing the second polishing wheel 42 on it to move towards one side of the sphere until it contacts the sphere, polishing it. After polishing, the second polishing wheel 42 needs to be removed first, and then the piston rod of the support cylinder 56 is controlled to remove the sphere from the support shaft 52, placing the sphere to be polished for further processing.

[0004] Existing processing equipment requires manual operation for clamping, polishing, and removing the ball, resulting in low processing efficiency. To address the problems in existing technology, we propose an automated machine for polishing ball valve bodies. Utility Model Content

The sliding plate 2 is slidably connected to the worktable 1, and a power component 8 for driving the sliding plate 2 is provided on the sliding plate 2. A limiting component 9 is provided on the worktable 1. The first polishing component 3 is located on the worktable 1, and the second polishing component 4 is located on the sliding plate 2. The controller 7 is connected to the first polishing component 3, the second polishing component 4, the ball support component 5, the feeding component 6, the power component 8, and the limiting component 9. The ball is stored in the feeding component 6. The controller 7 controls the feeding component 6 to automatically place the ball onto the ball support component 5, controls the ball support component 5 to move the ball between the first polishing component 3 and the second polishing component 4, and then controls the first polishing component 3 and the second polishing component 4 to polish the surface of the ball, realizing automatic feeding and processing of the ball, greatly improving the processing efficiency of the ball.

[0016] The feeding assembly 6 includes a fixed base 61, a storage bin 62, a guide rail 63, a first feeding cylinder 64, and a second feeding cylinder 65. The fixed base 61 is fixedly connected to the workbench 1, and has a through V-shaped groove for the storage bin 62 to slide. The lower end of the storage bin 62 protrudes from the V-shaped groove, and the guide rail 63 is fixedly connected to the lower end of the storage bin 62. The ball is stored in the storage bin 62. The guide rail 63 is inclined, with the end of the guide rail 63 near the storage bin 62 being the inclined upper end. The inclined arrangement of the guide rail 63 facilitates the movement of the ball towards the ball support member 5 under the action of gravity. The first feeding cylinder 64 is fixedly connected to the upper end face of the fixed base 61. The cross-section of the guide rail 63 is U-shaped, and the U-shaped opening of the guide rail 63 is vertically upward. The side wall of the guide rail 63 has a feeding port 66 for pushing the ball towards the ball support 5. The feeding port 66 is located on the side wall of the guide rail 63 near the ball support 5. The piston rod of the first feeding cylinder 64 is connected to the storage box 62. The base of the second feeding cylinder 65 is fixedly connected to the side wall of the guide rail 63.

After feeding is completed, the second feeding cylinder 65 resets, and the ball on the guide rail 63 moves to the feeding port 66 under the action of gravity. Controller 7 controls the piston rod of the first feeding cylinder 64 to extend, pushing the guide rail 63 away from the spherical support 5. The first feeding cylinder 64 is used to move the guide rail 63 (storage box 62) mainly to avoid interference between the spherical support 5 and the guide rail 63 when unloading.

[0017] The spherical support component 5 includes an electric rotary table 51, a support shaft 52, a support base 53, and a discharge cylinder 54.

The feeding assembly 6 is located on the side of the spherical support component 5 away from the first polishing assembly 3. The controller 7 is connected to the electric rotary table 51 and the discharge cylinder 54. During feeding, the controller 7 drives the electric rotary table 51 to rotate, rotating the support shaft 52 toward the feeding assembly 6 for feeding. After the material is loaded, the controller 7 controls the electric rotary table 51 to rotate 180° counterclockwise, rotating the ball between the first polishing assembly 3 and the second polishing assembly 4 for polishing. After polishing, the controller 7 controls the electric rotary table 51 to rotate 180° clockwise, and then controls the piston rod of the unloading cylinder 54 to move, pushing the ball off the support shaft 52 through the unloading push rod 55. After the ball is pushed off, the piston rod of the unloading cylinder 54 returns to its original position.

[0018] To facilitate the feeding assembly 6 pushing the ball onto the support shaft 52, the end of the support shaft 52 away from the support base 53 is tapered.

When processing the sphere, the controller 7 controls the moving motor 81 to rotate, which drives the sliding plate 2 to move towards the first polishing assembly 3 through the meshing of the gear 82 and rack 83. The sliding plate 2 contacts the first proximity switch 91, and the first proximity switch 91 feeds back a signal to the controller 7. The controller 7 then controls the moving motor 81 to stop rotating. After the sphere is processed, the controller 7 controls the moving motor to rotate in the opposite direction, driving the second polishing assembly 4 away from the first polishing assembly 3. When the sliding plate 2 contacts the second proximity switch 92, the second proximity switch 92 feeds back a signal to the controller 7, and the controller 7 then controls the moving motor 81 to stop rotating.
