[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the transfer block set on the support rod can be moved to the discharge port through the coordinated movement of the lifting dovetail slide and the ball screw transmission mechanism. The raw material bar located at the discharge port is pushed out of the feeding box by the discharge electric push rod. The raw material bar moves to the U-shaped groove position of the transfer block. Then, with the coordinated movement of the lifting dovetail slide and the ball screw transmission mechanism, the transfer block transports the raw material bar to the same horizontal axis as the chuck. The raw material bar on the transfer block is fed into the chuck, realizing automatic feeding, improving work efficiency, and being easy to use.

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.

[0026] Please see Figures 1-9 In this embodiment of the utility model, a machine tool loading mechanism includes a machine tool body 1, a loading box 6, and a transfer block 13. A chuck 2 is provided on one side of the machine tool body 1. A machining guide rail 3 is bolted to the top center of the machine tool body 1. A tool holder 4 is slidably connected to the machining guide rail 3. A tool head 5 is provided at the top of the upper motor of the tool holder 4. The loading box 6 is bolted to the machine tool body 1 above the chuck 2. A "<"-shaped loading slide 20 is provided inside the loading box 6 to prevent the raw material rod from bumping during loading. A discharge port 9 is provided on the bottom side of the loading slide 20. A discharge electric push rod 7 is fixedly connected to the side of the loading box 6 aligned with the discharge port 9. A lifting dovetail slide 10 is bolted to the back plate of 1. A ball screw drive mechanism 11 is bolted to the slide of the lifting dovetail slide 10. A support rod 12 is bolted to the slide of the ball screw drive mechanism 11. A transfer block 13 is bolted to the middle of the support rod 12. The transfer block 13 has a U-shaped groove inside. The centers of the claw 2, the discharge port 9 and the transfer block 13 are located on the same vertical axis. The lifting dovetail slide 10 and the ball screw drive mechanism 11 are used to transfer the raw material bar in the feeding box 6 to the claw 2 for fixing, realizing automatic feeding. The structure is simple and reliable, with a high degree of automation and is easy to use.

[0027] The top end of the transfer block 13 is bolted to a lower pressure cover 21. A connecting rod 26 is slidably connected to the center of the lower pressure cover 21. A limit nut 22 is threaded to the top of the connecting rod 26. A right-angled trapezoidal positioning block 24 is provided at the bottom of the connecting rod 26. A circular mounting groove 23 is provided at the bottom of the lower pressure cover 21. A spring 25 is provided in the mounting groove 23. The spring 25 is located between the lower pressure cover 21 and the positioning block 24. The positioning block 24 is used to fix one end of the raw material rod to prevent it from falling off due to excessive length, making it safer to use.

[0028] The top of the feeding box 6 is provided with a right-angled trapezoidal storage trough 8. The top of the storage trough 8 is connected to the feeding slide 20. The storage trough 8 can hold multiple raw material bars, reduce the frequency of workers replenishing materials, and improve work efficiency.

[0029] The machine tool body 1 is located on one side of the processing guide rail 3 and is connected to the slide rail 14 by bolts. A "T"-shaped sliding base 15 is slidably connected inside the slide rail 14. A first pulley 18 is rotatably connected to the bottom center of the sliding base 15. The first pulley 18 is slidably connected to the slide rail 14. A guide rod 16 is welded to the top center of the sliding base 15. The guide rod 16 is slidably connected to the support rod 12. The guide rod 16 provides auxiliary support to the top of the support rod 12 to prevent the support rod 12 from tilting due to excessive material weight and improve the feeding accuracy.

[0030] The slide rail 14 has symmetrically arranged limiting grooves 17 on both sides, and the sliding base 15 has symmetrically arranged second pulleys 19 on both sides. The second pulleys 19 are slidably connected to the limiting grooves 17 to prevent the sliding base 15 from slipping off the slide rail 14 and to increase the sliding stability of the guide rod 16 and the support rod 12.

[0031] The working principle of this utility model is as follows: Before use, the worker puts the raw material bars into the storage trough 8 of the feeding box 6. Under the action of gravity, the raw material bars are arranged sequentially along the feeding slide 20. When feeding is required, the lifting dovetail slide 10 moves to the top and the ball screw transmission mechanism 11 works, driving the support rod 12 to move to the feeding box 6. The support rod 12 drives the sliding base 15 at the bottom of the guide rod 16 to slide and connect with the slide rail 14 until the transfer block 13 is in contact with the side of the feeding box 6. The U-shaped groove on the transfer block 13 is aligned with the discharge port 9. At this time, the discharge electric push rod 7 works to push the bottom raw material bar into the U-shaped groove. When the raw material bar is pushed into the U-shaped groove of the transfer block 13, the inclined surface of the positioning pressure block 24 is pushed and the spring 25 is compressed. The positioning block 24 moves upward. When the raw material bar moves to the top of the U-shaped groove, the positioning block 24 fixes the top of the raw material bar under the elastic force of the spring 25 to prevent it from falling off due to excessive length, ensuring safe use. Afterward, the output end of the discharge electric push rod 7 retracts, and the new raw material bar falls into the discharge port 9. Under the coordinated movement of the lifting dovetail slide 10 and the ball screw transmission mechanism 11, the guide rod 16 slides with the support rod 12. The transfer block 13 on the support rod 12 moves to the same horizontal axis as the chuck 2 and moves towards the chuck 2. After the chuck 2 fixes the raw material bar, the support rod 12 moves to the middle position of the ball screw transmission mechanism 11 and rises to the top of the lifting dovetail slide 10, avoiding interference with machine tool processing and making it convenient to use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
