[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 、 Figure 2 and Figure 3, An embodiment provided by the present utility model: A post-positioned loading manipulator for valve centerless grinding includes a fixed block 1. An electric slide rail 2 is fixedly connected to the outside of the fixed block 1. An electric slider 5 is slidably connected to the outside of the electric slide rail 2. A connecting block 6 is fixedly connected to the outside of the electric slider 5. A moving rod 7 is fixedly connected to the inside of the connecting block 6. A spring 8 is sleeved on the outside of the moving rod 7. A linkage block 21 is fixedly connected to the inside of the connecting block 6. A movable block 22 is slidably connected to the outside of the linkage block 21. An installation groove 9 is provided at the top of the movable block 22. A middle block 10 is fixedly connected to the top of the movable block 22. A cylinder four 23 is fixedly connected to the inside of the middle block 10. Two rotating rods 24 are rotatably connected to the inner wall of the middle block 10. The other end of the rotating rod 24 is fixedly connected to a connecting piece 12. A plurality of limiting blocks 14 are fixedly connected to the outside of the fixed block 1. A valve body 11 is slidably connected to the outside of one of the limiting blocks 14. A cylinder one 13 is fixedly connected to the outside of the fixed block 1. The output end of the cylinder one 13 is fixedly connected to a guiding block 20. A stabilizing rod 3 is fixedly connected to the outside of the guiding block 20. A loading component is installed at the bottom of the fixed block 1. The loading component is used for loading the valve.

[0032] Further, first place the valve at the designated position. The electric slider 5 and the electric slide rail 2 are supporting facilities in the prior art. Then, the electric slider 5 moves upward along the electric slide rail 2, driving the connecting block 6 to move upward simultaneously, so that the movable block 22 drives the middle block 10 to move simultaneously. Start the cylinder four 23. When the output end of the cylinder four 23 retracts, the two rotating rods 24 approach each other, driving the two connecting pieces 12 to approach each other to clamp the valve body 11. At the same time, start the cylinder one 13, so that the output end of the cylinder one 13 drives the stabilizing rod 3 to move downward along the through hole of another limiting block 14 through the guiding block 20. When the valve body 11 contacts the bottom of the stabilizing rod 3, the outside of the movable block 22 slides along the outside of the linkage block 21. Then, under the elastic force of the spring 8, the valve body 11 can be buffered, ensuring the integrity of the valve during clamping. By clamping the valve body 11, it is beneficial to accurately position the valve, reducing the time and labor cost of manual operation.

[0033] Refer to Figure 1 , Figure 2 and Figure 4 , the loading component includes a supporting block 15. The top of the supporting block 15 is fixedly connected to the bottom of the fixed block 1. A cylinder two 16 is fixedly connected to the outside of the supporting block 15. The output end of the cylinder two 16 is fixedly connected to a pushing piece one 18. A cylinder three 17 is fixedly connected to the outside of the supporting block 15. The output end of the cylinder three 17 is fixedly connected to a pushing piece two 19; the cylinder two 16 and the cylinder three 17 are vertically distributed; the sizes of the pushing piece one 18 and the pushing piece two 19 are different.

[0034] Furthermore, the valve is connected to one end of the first pusher 18. The second cylinder 16 is activated, and the output end of the second cylinder 16 drives the first pusher 18 to move. Then, the valve is pushed to move simultaneously by the first pusher 18 for feeding, improving the accuracy of feeding. At this time, the valve is connected to one end of the second pusher 19, and the above steps are repeated. Feeding at different positions can be achieved through the second cylinder 16 and the third cylinder 17. At the same time, the sizes of the first pusher 18 and the second pusher 19 are different, enabling the device to adapt to valves of different sizes, making the device more versatile and improving production efficiency. The second cylinder 16 and the third cylinder 17 are vertically distributed, allowing the device to feed valves in different directions. The first pusher 18 and the second pusher 19 can adapt to valves of different sizes, further improving the flexibility of the device.

[0035] Refer to Figure 1 、 Figure 2 Figure 3 The bottom of the moving rod 7 is slidably connected to the inner wall of the installation groove 9. One end of the spring 8 is fixedly connected to the inner side of the connecting block 6, and the other end of the spring 8 is fixedly connected to the top of the movable block 22. The outer part of the stabilizing rod 3 is slidably connected to the through hole at the top of one of the limiting blocks 14. Two grooves are formed on the outer part of the middle block 10, and the outer part of the rotating rod 24 is slidably connected to the inner wall of the groove. A plurality of sliding rods 4 are connected to the outer side of the fixed block 1, and the inner part of the electric slider 5 is slidably connected to the outer part of the sliding rods 4.

[0036] Furthermore, the spring 8 is limited by the connecting block 6 and the movable block 22, making the force distribution of the spring 8 uniform, thereby extending the service life of the spring 8. Then, the valve body 11 is buffered by the elastic force of the spring 8, causing the moving rod 7 to slide along the inner wall of the installation groove 9 to ensure the effectiveness of the buffer. When the output end of the first cylinder 13 drives the stabilizing rod 3 to move downward through the guiding block 20, the stabilizing rod 3 slides along the through hole of one of the limiting blocks 14, increasing the stability of the stabilizing rod 3. When the fourth cylinder 23 drives the rotating rod 24 to rotate, the rotating rod 24 slides along the inner wall of the groove. When the electric slider 5 moves, the electric slider 5 slides along the outer part of the plurality of sliding rods 4, which is beneficial to ensuring the stability and reliability of the electric slider 5.

[0037] Working principle: First, place the valve in the specified position. Then, the electric slider 5 moves upward along the electric slide rail 2, driving the connecting block 6 and the movable block 22 to move upward simultaneously, and further driving the middle block 10 to move. Start the cylinder four 23. When the output end of the cylinder four 23 retracts, the two rotating rods 24 move closer to each other, driving the two connecting pieces 12 to move closer to clamp the valve body 11. At the same time, start the cylinder one 13, so that the output end of the cylinder one 13 drives the stabilizing rod 3 to move downward through the guide block 20. When the valve body 11 contacts the stabilizing rod 3, the moving rod 7 slides along the inner wall of the installation groove 9. Under the elastic force of the spring 8, the valve body 11 can be buffered, effectively preventing the stabilizing rod 3 from damaging the valve. The function of the stabilizing rod 3 is to prevent the valve body 11 from sliding up and down, increasing the stability of clamping. By clamping the valve body 11, the stable position of the valve can be ensured, which is beneficial to maintaining the stability of the valve.

[0038] In addition, connect the valve to the end of the pushing member one 18 away from the cylinder two 16. Start the cylinder two 16, and drive the pushing member one 18 to move through the output end of the cylinder two 16, thereby driving the valve to move simultaneously for precise feeding. At this time, connect the valve to the end of the pushing member two 19 away from the cylinder three 17, and repeat the above steps to achieve feeding at different positions. At the same time, the sizes of the pushing member one 18 and the pushing member two 19 are different, enabling the device to adapt to valves of different sizes, meeting more feeding requirements and making the device more flexible.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
