[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with 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 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.

[0029] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a part grinding device for the production and manufacturing of a pressure valve, including a base 1. An opening groove 3 is provided at the top of the base 1. A bidirectional lead screw 4 is rotatably connected to the left side of the base 1. The right end of the bidirectional lead screw 4 penetrates through the opening groove 3. Movable plates 5 are threadedly connected to both the left and right sides of the outer wall of the bidirectional lead screw 4. Movable shafts 6 are rotatably connected to the far sides of the two movable plates 5. One end of the movable shaft 6 penetrates through the movable plate 5 and is fixedly connected to a hollow plate 7. A first lead screw 8 is threadedly connected to the top of the hollow plate 7. The middle and lower part of the first lead screw 8 penetrates through the hollow plate 7 and is threadedly connected to an upper clamping block 12. Lower clamping blocks 9 are fixedly connected to the middle and lower parts of the adjacent sides of the two hollow plates 7. A clamping plate 10 is provided on one side of the top of the lower clamping block 9. A second lead screw 11 is threadedly connected to the top of the clamping plate 10. The bottom end of the second lead screw 11 sequentially penetrates through the clamping plate 10 and the lower clamping block 9. An adjusting mechanism 2 is provided on the upper side of the base 1. A placing plate 13 is fixedly connected to the middle of the inner top end of the opening groove 3. The two movable plates 5 are both slidably connected to the inside of the opening groove 3. One side of each of the two upper clamping blocks 12 is slidably connected to the inside of the corresponding hollow plate 7;

[0030] Specifically, when the valve part to be processed is a square workpiece, rotating the bidirectional lead screw 4 at this time can drive the movable plates 5 on both sides to move towards the middle. As the movable plates 5 move, the clamping plate 10 will also move accordingly, thereby performing limit clamping on the square workpiece. This limit clamping method is not only stable and reliable, but also simple and convenient to operate. When it is necessary to clamp a special-shaped workpiece, first loosen the second lead screw 11 at this time, and the clamping plate 10 can be easily removed. Then rotate the first lead screw 8, which can drive the upper clamping block 12 to move downward. The cooperation between the upper clamping block 12 and the lower clamping block 9 is very precise, and can tightly clamp the special-shaped workpiece to ensure that it will not move or deform during the processing. The ingenious design of this limit clamping device lies in its flexibility and versatility. By simple adjustment and disassembly, it can adapt to workpieces of different shapes and sizes, which not only improves production efficiency, but also reduces production costs.

[0031] Referring to Figure 1 , Figure 2 and Figure 3, the adjusting mechanism 2 includes an L-shaped plate 201. The L-shaped plate 201 is fixedly connected to the right side of the base 1. A fixed frame 203 is arranged inside the L-shaped plate 201. A servo motor 204 is fixedly connected to the front side of the fixed frame 203. The output end of the servo motor 204 penetrates through the fixed frame 203 and is fixedly connected to a first rotating rod 205. A driving gear 206 is fixedly connected to the outer side of the first rotating rod 205. A second rotating rod 207 is rotatably connected to the inside of the fixed frame 203. A driven half gear 208 is fixedly connected to the outer side of the second rotating rod 207. A micro motor 209 is fixedly connected to the bottom of the driven half gear 208. The output end of the micro motor 209 is fixedly connected to a curved rod 210. A grinding wheel 211 is fixedly connected to the bottom end of the curved rod 210. A transmission assembly is arranged at the rear side of the top of the base 1. The transmission assembly includes a support rod 212 and a transmission belt 217. The support rod 212 is fixedly connected to the rear side of the top of the base 1. The top end of the support rod 212 is rotatably connected to a hollow column 213. A movable rod 214 is slidably connected to the left and right sides inside the hollow column 213. A first pulley 215 is fixedly connected to one side of the outer wall of the movable rod 214. A second pulley 216 is fixedly connected to the outer side of the movable shaft 6. The two second pulleys 216 are respectively connected to the corresponding first pulleys 215 through the transmission belt 217 for transmission connection;

[0032] Specifically, the servo motor 204 can drive the first rotating rod 205 to rotate, and the driving gear 206 on its outer side also starts to rotate. Since the driving gear 206 meshes with the driven half gear 208, the driven half gear 208 will also rotate with the rotation of the driving gear 206. At this time, the grinding wheel 211 will tilt left and right, enabling the grinding wheel 211 to adapt to the grinding requirements at different angles. Then, the micro motor 209 can drive the grinding wheel 211 to rotate, thus realizing multi-angle grinding of the valve parts. This grinding method not only improves the grinding efficiency but also effectively guarantees the grinding quality. In addition, to achieve all-round grinding of the valve parts, at this time, rotate the left movable shaft 6, and the second pulley 216 on its outer side will rotate accordingly. At the same time, the first pulley 215 on the outer side of the left movable rod 214 is connected to the second pulley 216 through the transmission belt 217, so it will also rotate. In this way, the hollow column 213 will rotate accordingly, which can drive the right movable rod 214 to rotate, and then drive the clamped valve parts to flip, so as to perform all-round grinding on the valve parts.

[0033] Refer to Figure 1 , the adjusting mechanism 2 further includes a hydraulic rod 202. The hydraulic rod 202 is fixedly connected to the inner top of the L-shaped plate 201. The output end of the hydraulic rod 202 is fixedly connected to the top of the fixed frame 203;

[0034] Specifically, the hydraulic rod 202 can drive the fixed frame 203 to move up and down so that the grinding mechanism can contact the parts to be processed, thereby improving the practicability of the device.

[0035] Referring to Figure 1 , a controller 14 is fixedly connected to the front end of the right side of the top of the base 1. The controller 14 is electrically connected to the hydraulic rod 202, the servo motor 204, and the micro motor 209 respectively. A protective cover 15 is arranged outside the controller 14, and one side of the protective cover 15 is rotatably connected to the top of the base 1;

[0036] Specifically, the controller 14 can control the operation of the hydraulic rod 202, the servo motor 204, and the micro motor 209, and the provided protective cover 15 can protect the controller 14 from being damaged by external factors.

[0037] Working principle: When using this device, first observe the shape of the valve part to be processed. When the shape of the valve part to be processed is a square workpiece, at this time, rotating the bidirectional lead screw 4 can drive the movable plates 5 on both sides to move towards the middle, and the clamping plates 10 will move accordingly to limit and clamp the square workpiece. When it is necessary to limit and clamp a special-shaped workpiece, only need to loosen the second lead screw 11 to remove the clamping plate 10, and then rotate the first lead screw 8 to drive the upper clamping block 12 to move downward. At this time, through the cooperation between the upper clamping block 12 and the lower clamping block 9, the special-shaped workpiece can be limited and clamped, so that it can be applicable to workpieces of different shapes and sizes, meeting the needs of users. And when it is necessary to polish the valve part in all aspects, at this time, the servo motor 204 can drive the first rotating rod 205 to rotate, the driving gear 206 will rotate accordingly, and the driven half gear 208 will also rotate because it meshes with the driving gear 206, thus driving the grinding wheel 211 to tilt left and right. At this time, the micro motor 209 can drive the grinding wheel 211 to rotate, and then the valve part can be polished at multiple angles. Then rotate the left movable shaft 6, and the second pulley 216 on its outer side will rotate accordingly. The first pulley 215 on the outer side of the left movable rod 214 will also rotate through the transmission belt 217, and the hollow column 213 will rotate accordingly to drive the right movable rod 214 to rotate. Similarly, the right movable shaft 6 will rotate accordingly. At this time, the clamped valve part can be flipped, so that the valve part can be polished in all aspects, and then the practicability of this device can be improved.

[0038] 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.
