Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 5 As shown, this utility model embodiment provides an automatic feeding mechanism for a CNC lathe, including a frame 1, a storage carrier plate 21, a pressure plate 22, a lifting and sliding mechanism 3, a guide plate 4, a lifting and receiving mechanism 5, a support frame 6, and a pushing mechanism 7. The storage carrier plate 21 is disposed on the frame 1, and the top of the storage carrier plate 21 has a first slope 211. The pressure plate 22 is disposed above the storage carrier plate 21, and a feeding channel 200 is formed between the pressure plate 22 and the storage carrier plate 21. The feeding channel 200 is used to place the bars to be processed in rows. The first slope 211 allows the bars to slide into the feeding channel 200 in an orderly manner under the action of gravity. The pressure plate 22 can provide a limiting and blocking effect on the bars below, so that the bars are closely arranged in the feeding channel 200.

[0033] A baffle plate 201 is provided at the end of the feeding channel 200. The baffle plate 201 is used to prevent the bar from sliding out of the feeding channel 200. There is a lifting gap between the baffle plate 201 and the pressure plate 22. The lifting and sliding mechanism 3 is located on the lifting gap. The lifting and sliding mechanism 3 is used to lift the bar in the lifting gap upward. The baffle plate 201 can prevent the bar from sliding out of the feeding channel 200, so that the bar can be stably stopped in the feeding channel 200. The lifting gap formed between the baffle plate 201 and the pressure plate 22 allows the lifting and sliding mechanism 3 to lift the bar upward and push the bar into the next process flow.

[0034] The material support frame 6 is located at the side end of the storage carrier plate 21, and the guide plate 4 is located between the material support frame 6 and the storage carrier plate 21. The guide plate 4 is used to guide the conveying rod that is lifted upward, so that the rod can smoothly enter the material support frame 6 along a predetermined path.

[0035] like Figure 2 and Figure 5 As shown, multiple lifting and receiving mechanisms 5 are spaced apart along the extension direction of the material support frame 6. Each lifting and receiving mechanism 5 includes a lifting cylinder 51 and a receiving frame 52. The movable end of the lifting cylinder 51 is facing upward and connected to the receiving frame 52. The receiving frame 52 is used to receive bars, and the lifting cylinder 51 is used to drive the receiving frame 52 to move up and down. When the receiving frame 52 rises, it can receive bars conveyed from the guide plate 4; when the lifting cylinder 51 descends, it can place the bars on the receiving frame 52 onto the material support frame 6.

[0036] The pushing mechanism 7 is located on the side of the support frame 6. The pushing mechanism 7 is used to apply a pushing force to the bar on the support frame 6 to push it into the CNC lathe for loading and processing. The entire loading process is automated and stable, effectively improving the loading efficiency of the bar.

[0037] like Figure 3 and Figure 4 As shown, the lifting and sliding mechanism 3 further includes a lifting cylinder 31, a rotating shaft 32, a connecting rod arm 33, a lifting slide plate 34, and a sliding base 35. The sliding base 35 is disposed on the side wall of the storage plate 21, and the lifting slide plate 34 is located inside the sliding base 35. The lifting slide plate 34 can move up and down in the vertical direction. The top of the lifting slide plate 34 has a second slope 341, which is used to slide the bar onto the guide plate 4 when the lifting slide plate 34 lifts it. The rotating shaft 32 is rotatably disposed at the bottom of the frame 1. The movable end of the lifting cylinder 31 is connected to the rotating shaft 32 to drive the rotating shaft 32 to rotate. The end of the rotating shaft 32 is connected to the bottom of the lifting slide plate 34 through the connecting rod arm 33. The connecting rod arm 33 is used to push the lifting slide plate 34 up and down as the rotating shaft 32 rotates. When the lifting cylinder 31 drives the rotating shaft 32 to rotate, the lifting plate 34 can be moved up and down through the connecting rod swing arm 33. During the upward process, the lifting plate 34 can lift the bar in the lifting gap. At this time, the bar can slide down onto the guide plate 4 under the action of gravity and smoothly enter the subsequent receiving rack 52.

[0038] like Figure 2As shown, the material support frame 6 further includes a support body 61, parallel rollers 62 and supporting inclined rollers 63. A plurality of parallel rollers 62 are spaced apart along the extension direction of the support body 61. The parallel rollers 62 are used to support the bar. The supporting inclined rollers 63 are located on both sides of the support body 61. The supporting inclined rollers 63 are used to limit the lateral movement of the bar on the parallel rollers 62.

[0039] like Figure 2 As shown, the pushing mechanism 7 further includes a pushing cylinder 71 and a pushing plate 72. The movable end of the pushing cylinder 71 is connected to the pushing plate 72. The pushing cylinder 71 is used to push the pushing plate 72 toward the extension direction of the support frame 6. When the pushing cylinder 71 is activated, it can push the pushing plate 72 forward to push the bar on the support frame 6 into the processing area of ​​the CNC lathe.

[0040] like Figure 4 As shown, the guide plate 4 further has a third slope 41 at its top, which is used to slide the bar onto the receiving rack 52. It should be noted that the first slope 211, the second slope 341, and the third slope 41 have the same inclination angle, thereby improving the stability of the bar conveying.

[0041] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
