[0017] See appendix Figure 1-2As shown, a feeding mechanism for a valve body processing machine tool in this embodiment includes a lifting plate 1, several guide mechanisms, a base plate 8, a pair of bearings 12, a gear 13, a lifting rod 15, a rack 16, and a drive shaft 17. The guide mechanism includes a guide rod 2, a fixing ring 3, and a guide cylinder 4. One end of the guide rod 2 is fixedly connected to the lifting plate 1, and the other end passes through the guide cylinder 4. The fixing ring 3 is connected to the bottom of the guide cylinder 4. The base plate 8 has a through hole 18 at its center, and the base plate 8 is arranged opposite to the lifting plate 1. The lifting rod 15 is connected to the center of the bottom surface of the lifting plate 1. The lifting rod 15 extends downward through the through hole 18. A rack 16 is provided on one side of the lifting rod 15. A gear 13 is meshed on the rack 16. The drive shaft 17 is fixedly connected to the center of the gear 13. Bearings 12 are provided at both ends of the drive shaft 17. The bearings 12 are connected to bearing seats 11, and the bearing seats 11 are fixedly connected to the base plate 8. A drive mechanism is connected to the end of the drive shaft 17.

[0018] The top end of the lifting rod 15 is fixedly connected to the lifting plate 1, and the lower end is inserted into the through hole 18 of the base plate 8. A rack 16 is provided on one side of the lifting rod 15, and a gear 13 is meshed on the rack 16. A drive shaft 17 is fixedly connected through the center of the gear 13, and a drive mechanism is connected to the end of the drive shaft 17. Activating the drive mechanism rotates the drive shaft 17, causing the gear 13 to rotate accordingly. The gear 13 drives the rack 16, the lifting rod 15, and the lifting plate 1 to rise, lifting the valve body pre-placed on the lifting plate 1, and then moving it into the machine tool for processing. The technical solution of this patent application is particularly suitable for the loading and processing of small and medium-sized valve bodies, replacing manual handling and lifting, and reducing labor fatigue.

[0019] The drive mechanism includes a motor 5, a reducer 6, a vertical plate 7, a drive shaft 9, and a coupling 10. The vertical plate 7 is fixedly connected to one end of the base plate 8, the reducer 6 is fixedly connected to the vertical plate 7, the motor 5 is fixedly connected to the reducer 6, one end of the drive shaft 9 is connected to the reducer 6, and the other end is connected to the drive shaft 17 through the coupling 10.

[0020] The motor 5 is started, which drives the drive shaft 17 and gear 13 to rotate via the reducer 6, drive shaft 9, and coupling 10. The reducer 6 reduces the speed and increases the torque. The upright plate 7 provides support for the motor 5, reducer 6, and drive shaft 9.

[0021] To enhance the strength of the base plate 8, this invention further comprises: a reinforcing plate 14 superimposed on the base plate 8, and the lifting rod 15 passing through the reinforcing plate 14. Preferably, the reinforcing plate 14 is arranged around the bottom of the through hole 18. Lubricating oil is applied around the reinforcing plate 14 and the through hole 18.

[0022] To facilitate the meshing connection between the lifting rod 15 and the gear 13, the present invention is further configured such that: the lifting plate 1 is a rectangular rod, the through hole 18 is a rectangular hole, and the lifting rod 15 matches and fits the through hole 18.

[0023] To prevent interference between the lifting plate 1 and the bearing seat 11 and the upright plate 7 when the lifting plate 1 is lowered, this utility model is further configured such that the top end of the guide cylinder 4 is higher than the top end of the bearing seat 11 and the upright plate 7. Four guide mechanisms are connected to the four corners of the lifting plate 1. When the lifting plate 1 is lowered, its four corners overlap the top end of the guide cylinder 4, maintaining a distance from the bearing seat 11 and the upright plate 7.

[0024] Preferably, a plurality of pulleys 19 and slide rods 20 are provided on the inner side of the through hole 18. The pulleys 19 rotate on the slide rods 20, and the slide rods 20 are fixedly connected to the side of the through hole 18. The side of the lifting rod 15 abuts against the pulleys 19.

[0025] In summary, the feeding mechanism for the valve body processing machine tool shown in this utility model is used as follows: the fixing ring 3 is fixedly connected to the cement floor by expansion bolts (not shown). Several receiving holes are provided below the cement floor (not shown). One end of the guide rod 2 is fixedly connected to the lifting plate 1, and the other end passes through the guide cylinder 4 and extends into the receiving hole below the cement floor. The fixing ring 3 is connected to the bottom of the guide cylinder 4, and the guide cylinder 4 guides the guide rod 2 to move vertically. Because several guiding mechanisms are connected to the lifting plate 1, the lifting plate 1 cannot rotate.

[0026] The top end of the lifting rod 15 is fixedly connected to the lifting plate 1, and the bottom end passes through the through hole 18, extending into the receiving hole below the cement floor. Therefore, the lifting rod 15 can only move up and down within the through hole 18. Preferably, the bearing 12 is a thrust ball roller bearing 12. The bearing housing 11 and the bearing 12 provide support for the drive shaft 17, which can only rotate between a pair of bearings 12. The motor 5 is started, and the speed is reduced by the reducer 6, increasing the torque, which rotates the gear 13 through the transmission shaft 9, coupling 10, and drive shaft 17. The gear 13 meshes with the rack 16, driving the lifting rod 15, which is connected to the rack 16, to rise. The valve body, which is pre-placed on the lifting plate 1, is lifted and then moved into the machine tool for processing. The technical solution of this patent application is particularly suitable for the loading and processing of small and medium-sized valve bodies, replacing manual handling and lifting, and reducing fatigue. Afterward, the motor 5 rotates in reverse, driving the gear 13 to rotate in reverse through the reducer 6, transmission shaft 9, coupling 10, and drive shaft 17. The rack 16 and lifting rod 15, which are meshed with the gear 13, descend, and the lifting plate 1 descends accordingly. The lifting rod 15 and the guide rod 2 extend into the receiving hole below the cement floor.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
