Description

Technical Field

[0001] This utility model discloses a sphere circular runout detection device, belonging to the field of valve accessory processing technology. Background Technology

[0002] The valve ball is a component of a ball valve, which is commonly used in pipelines to control the flow of substances within the pipeline. The main function of the valve ball is to control the flow and stop of substances in the pipeline. The valve ball is usually spherical with a flow hole on its arc surface. The rotation of the valve ball controls the flow and stop of substances in the pipeline. After processing, the valve ball needs to be tested for roundness, also known as round runout tolerance testing. A ball that meets the processing requirements can reduce wear between it and the valve seat during valve opening and closing. Existing testing devices are inconvenient to operate manually and can only test a single position of the ball, resulting in a large error in the test results. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, a sphere circular runout detection device includes a detection platform 1, a rotating platform 2, and a measuring instrument 6. The rotating platform 2 is rotatably mounted on the detection platform 1. The detection platform 1 is equipped with a motor for driving the rotating platform 2 to rotate. The rotating platform 2 has a telescopic clamp for clamping the sphere. The measuring instrument 6 is placed horizontally, and a movable seat 5 is detachably installed below it. The detection platform 1 is equipped with a first adjustment component and a second adjustment component for adjusting the relative position of the movable seat 5.

[0020] The first adjustment assembly includes a fixed block 9, a first guide rod 11, a first screw 10, and a slider 13. The second adjustment assembly is mounted on the slider 13, and the fixed block 9 is mounted on the detection table 1. The two ends of the first guide rod 11 and the first screw 10 are rotatably connected to the detection table 1 and the fixed block 9, respectively. The middle part of the first screw 10 is threadedly connected to the slider 13. The first guide rod 11 and the slider 13 are slidably arranged. The second adjustment assembly includes a mounting frame 12, a second guide rod 7, and a second screw 8. The mounting frame 12 is fixed on the slider 13. The two ends of the second guide rod 7 and the second screw 8 are rotatably connected to the mounting frame 12 and the slider 13, respectively. The middle part of the second screw 8 is threadedly connected to the movable seat 5. The second guide rod 7 and the movable seat 5 are slidably arranged. When the first screw 10 is rotated, the slider 13 slides along the first guide rod 11, which can drive the movable seat 5 and the measuring instrument 6 closer to the rotating table 2. When the second screw 8 is rotated, the height of the measuring instrument 6 and the movable seat 5 can be changed, thereby enabling the measurement of the circular runout of the sphere at different heights. The operation is simple and convenient.

[0021] The bottom of the measuring instrument 6 is provided with a lug 22, and the movable seat 5 is provided with a groove for installing the lug 22. The movable seat 5 is also provided with a pin 21 that connects to the lug 22. By relying on the connection between the pin 21 and the lug 22, the measuring instrument 6 can be horizontally installed on the movable seat 5, and the probe of the measuring instrument 6 can be aligned with the rotating table 2.

[0022] The telescopic clamp includes a drive block 16, a telescopic assembly, an adjusting bolt 4, and a first spring 18. The rotating platform 2 has a boss structure and a mounting post 3 is provided on the rotating platform 2. A mounting cavity is provided between the mounting post 3 and the rotating platform 2. The drive block 16 is slidably disposed in the mounting cavity, and the lower end of the drive block 16 has three guide slopes 15. The distance from the upper end of the guide slope 15 to the center of the mounting post 3 is greater than the distance from the lower end of the guide slope 15 to the center of the mounting post 3. The telescopic assembly is horizontally installed between the rotating platform 2 and the mounting post 3, and one end of the telescopic assembly abuts against the guide slope 15. Both ends of the first spring 18 abut against the rotating platform 2 and the drive block 16, respectively. The middle part of the adjusting bolt 4 is threadedly connected to the mounting post 3, and one end of the adjusting bolt 4 abuts against the drive block 16. The telescopic assembly includes a telescopic rod 17 and a second spring 19. A mounting cavity is provided between the mounting post 3 and the rotating platform 2. The slide groove 20 and the telescopic rod 17 have a stepped shaft structure, with the smaller diameter end extending to the outside of the rotating platform 2. The second spring 19 is sleeved on the outside of the telescopic rod 17 and applies a force to the telescopic rod 17 against the guide slope 15. When the adjusting bolt 4 is rotated, causing the drive block 16 to slide downward and compress the first spring 18, the position of the telescopic rod 17 against the guide slope 15 changes. The guide slope 15 pushes the telescopic rod 17 to compress the second spring 19, and one end of the telescopic rod 17 extends to the outside of the rotating platform 2 until one end of the telescopic rod 17 contacts the center hole of the ball, thereby clamping the ball. After the test is completed, the adjusting bolt 4 is rotated in the opposite direction, causing the drive block 16 to move upward under the action of the first spring 18. In this way, the telescopic rod 17 retracts back into the rotating platform 2 under the action of the second spring 19, thus releasing the clamping of the ball.

[0023] Multiple positioning pins 14 are also provided between the mounting column 3 and the rotating platform 2. The multiple positioning pins 14 are distributed at equal angles around the center of the rotating platform 2. The positioning pins 14 can position the relative position of the mounting column 3 and the rotating platform 2, so that the telescopic rod 17 and the drive block 16 can be smoothly installed between the rotating platform 2 and the mounting column 3.

[0024] Working principle: When testing the sphere, the mounting post 3 passes through the center hole of the sphere, and then the adjusting bolt 4 is rotated, causing the adjusting bolt 4 to drive the drive block 16 downward. This compresses the first spring 18. Relying on the relative sliding of the guide slope 15 and the telescopic rod 17, the telescopic rod 17 extends out of the rotating platform 2. The three telescopic rods 17 clamp the inner wall of the center hole of the sphere. Then, by rotating the first screw 10 and the second screw 8, the slider 13 and the movable seat 5 move horizontally and vertically, thereby adjusting the position of the measuring gauge 6. Finally, the probe of the measuring gauge 6 contacts the surface of the sphere. After the measuring gauge 6 is zeroed, the motor drives the rotating platform 2 to rotate, causing the sphere to rotate. By observing the changes in the value of the measuring gauge 6, a set of circular runout data of the sphere can be obtained. The position of the measuring gauge 6 for the next measurement can be adjusted by the first screw 10 and the second screw 8. This allows for multiple measurements of the sphere, resulting in more accurate measurement data.
