[0020] After that, the hydraulic rod 10 drives the second guide plate 11 to move vertically downward, and the second guide plate 11 drives the two sets of clamping plates 16 on it to move vertically downward. Then, the second stepping motor 13 is controlled to operate by the control panel 32, the second screw rod 14 is driven to rotate by the second stepping motor 13, and the two sets of sliding plates 15 are driven to move synchronously relative to each other by the second screw rod 14. The two sets of clamping plates 16 are driven to move synchronously relative to each other by the two sets of sliding plates 15, and the two sets of clamping plates 16 clamp and fix the valve seat circle 30. In this process, the moving plate 19 on the clamping plate 16 first contacts the valve seat circle 30. When the clamping plate 16 is in contact with the side wall of the valve seat circle 30, the moving plate 19 is completely pushed into the plate groove 18, and the first electrode piece 21 is in contact with the second electrode piece 22. At this time, the indicator light 17 on the clamping plate 16 is turned on, and the indicator light 17 sends an electric signal to the control panel 32.

At this time, the valve seat circle 30 is located above the conveyor belt 27. Then, the hydraulic rod 10 drives the second guide plate 11 to move vertically downward, and the clamping plate 16 clamping the valve seat circle 30 moves vertically downward and releases the valve seat circle 30. That is, the valve seat circle 30 on the first workbench 2 is moved to the conveyor belt 27, realizing the efficient unloading of the valve seat circle 30. This structure can control the clamping force of the valve seat circle 30, which is beneficial to improve the protection of the valve seat circle 30.

[0022] Please refer to Figure 5As shown, the base 1 is provided with a second workbench 23 mounted by a support, and a feeding structure is mounted on the side wall of the second workbench 23, which has the same structure as the discharging structure. The base 1 is provided with a support frame 31, and a control panel 32 is mounted on the side wall of the support frame 31. The control panel 32 is connected with the first stepper motor 5, the second stepper motor 13 and the indicator light 17 through an internal circuit. The support frame 31 is provided with a first motor 24 mounted by a machine base on the side wall thereof. Two groups of rotating shafts 25 are rotatably mounted on the support frame 31. The output shaft of the first motor 24 is fixedly connected with one of the rotating shafts 25. Rollers 26 are fixedly sleeved on the rotating shafts 25. A conveying belt 27 is sleeved on the two groups of rollers 26. Sprockets 28 are fixedly sleeved on the rotating shafts 25. A chain 29 is sleeved on the two groups of sprockets 28. The valve seat inserts 30 are placed on the first workbench 2, the second workbench 23 and the conveying belt 27, respectively. When the existing discharging mechanism finishes discharging the valve seat inserts 30, it is difficult to quickly feed the valve seat inserts 30 to the next process, which leads to a low production efficiency of the valve seat inserts 30. The valve seat inserts 30 are moved to the conveying belt 27, and then the first motor 24 is operated to drive one of the rotating shafts 25 to rotate, which drives one of the sprockets 28 to rotate, which drives the chain 29 to rotate, which drives the other sprocket 28 to rotate, which drives the other rotating shaft 25 to rotate, i.e., the two groups of rotating shafts 25 rotate synchronously, which drives the two groups of rollers 26 to rotate synchronously, which drives the conveying belt 27 to rotate, which conveys the valve seat inserts 30 to quickly move to the next process. Then, the feeding structure of the next process is operated to move the valve seat inserts 30 on the conveying belt 27 to the second workbench 23, which realizes quick feeding of the valve seat inserts 30 and is beneficial to improving the production efficiency of the valve seat inserts 30.

[0023] The working principle is that in the process of discharging the valve seat ring 30, since the clamping force of the clamp cannot be controlled, the clamping force is easy to be too large to cause damage to the valve seat ring 30, thereby causing poor protection of the valve seat ring 30. After the valve seat ring 30 completes a process on the first workbench 2, the first stepping motor 5 operates to drive the first lead screw 6 to rotate, the first lead screw 6 drives the guide block 7 on it to move horizontally to the left, the guide block 7 drives the moving frame 8 to move horizontally to the left, the moving frame 8 drives the hydraulic cylinder 9 and the hydraulic rod 10 to move horizontally to the left, the hydraulic rod 10 drives the second guide plate 11 to move horizontally to the left, so that the clamping assembly moves above the valve seat ring 30. Then the hydraulic cylinder 9 operates, the hydraulic rod 10 drives the second guide plate 11 to move vertically downward, the second guide plate 11 drives the two groups of clamping plates 16 on it to move vertically downward, then the second stepping motor 13 is controlled to operate through the control panel 32, the second stepping motor 13 drives the second lead screw 14 to rotate, the second lead screw 14 drives the two groups of sliding plates 15 on it to move synchronously relative to each other, the two groups of sliding plates 15 drive the two groups of clamping plates 16 to move synchronously relative to each other, and the two groups of clamping plates 16 clamp and fix the valve seat ring 30. In this process, the moving plate 19 on the clamping plate 16 first contacts the valve seat ring 30, and when the clamping plate 16 is in contact with the side wall of the valve seat ring 30, the moving plate 19 is completely pushed into the plate groove 18, and the first electrode piece 21 is in contact with the second electrode piece 22. At this time, the indicator light 17 on the clamping plate 16 is turned on, and the indicator light 17 sends an electric signal to the control panel 32. The indicator lights 17 on the two groups of clamping plates 16 successively send electric signals to the control panel 32. When the control panel 32 receives the second electric signal, the control panel 32 controls the second stepping motor 13 to stop operating. At this time, the clamping force of the clamping plate 16 on the valve seat ring 30 is moderate, avoiding damage to the valve seat ring 30 caused by excessive clamping force, and achieving protection of the valve seat ring 30. Then the hydraulic rod 10 drives the second guide plate 11 to move vertically upward, the clamping plate 16 clamping the valve seat ring 30 moves vertically upward, then the guide block 7 drives the moving frame 8 to move horizontally to the right, and the clamping plate 16 clamping the valve seat ring 30 moves horizontally to the right. At this time, the valve seat ring 30 is above the conveyor belt 27, then the hydraulic rod 10 drives the second guide plate 11 to move vertically downward, the clamping plate 16 clamping the valve seat ring 30 moves vertically downward and releases the valve seat ring 30, that is, the valve seat ring 30 on the first workbench 2 is moved to the conveyor belt 27, achieving efficient discharging of the valve seat ring 30. This structure can control the clamping force of the valve seat ring 30, and is conducive to improving the protection of the valve seat ring 30.The existing blanking mechanism is difficult to quickly feed the valve seat ring 30 to the next step after the blanking of the valve seat ring 30 is completed, thereby resulting in low production efficiency of the valve seat ring 30. The valve seat ring 30 is moved to the conveying belt 27, and then the first motor 24 is operated to drive one of the rotating shafts 25 to rotate, the rotating shaft 25 drives one of the sprockets 28 to rotate, the sprocket 28 drives the chain 29 to rotate, the chain 29 drives the other sprocket 28 to rotate, the sprocket 28 drives the other rotating shaft 25 to rotate, that is, the two groups of rotating shafts 25 rotate synchronously, the two groups of rotating shafts 25 drive the two groups of rollers 26 to rotate synchronously, the two groups of rollers 26 drive the conveying belt 27 to rotate, and the conveying belt 27 conveys the valve seat ring 30, so that the valve seat ring 30 is quickly moved to the next step.
