[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1~Figure 5 As shown, this embodiment proposes a processing machine tool with automatic feeding, including a machine tool body 1, one end of the top of the machine tool body 1 is fixedly connected to a support frame 2, the top of the support frame 2 is fixedly connected to a material storage box 3, the bottom end of the material storage box 3 is equipped with a material discharge assembly 4, the top of one end of the material storage box 3 is fixedly connected to a transmission frame 5, a feeding assembly 6 is arranged inside the transmission frame 5, the material discharge assembly 4 includes a positioning seat 7, a driving motor 8 and a driving bevel gear 9, the bottom end of the material storage box 3 is fixedly connected to the positioning seat 7, one end of the positioning seat 7 is fixedly connected to the driving motor 8, and the output end of the driving motor 8 is fixedly connected to the driving bevel gear 9;

[0025] The blanking assembly 4 also includes a blocking rack 10, a limiting rack 11, a blocking frame 12, an assembly plate 13 and a displacement rod 14. The top and bottom ends of the driving bevel gear 9 are respectively meshed and connected with the blocking rack 10 and the limiting rack 11. One end of the blocking rack 10 is fixedly connected to the blocking frame 12, one end of the limiting rack 11 is fixedly connected to the assembly plate 13, both ends of the assembly plate 13 are slidably connected to the displacement rod 14, one end of the displacement rod 14 is fixedly connected to the positioning frame 15, the other end of the displacement rod 14 is fixedly connected to the limiting plate 16, and a coil spring 17 is fixedly connected between the limiting plate 16 and the assembly plate 13;

[0026] It can be understood that the driving bevel gear 9 is driven to rotate by the driving motor 8, so that the driving bevel gear 9 simultaneously moves the blocking rack 10 and the limiting rack 11, so as to drive the blocking rack 10 and the limiting rack 11 to move toward each other, and the displacement of the blocking rack 10 will make the blocking frame 12 gradually contact the blockage of the bottom end of the material storage box 3, and make the limiting rack 11 drive the positioning frame 15 to contact the second bar material to position it, and when the blocking frame 12 releases the blockage of the material storage box 3, the bar material above the blocking frame 12 will pass through the bottom of the material storage box 3 and fall into the inner side of the bearing seat 22, and the second bar material will not fall because it is positioned by the positioning frame 15;

[0027] In detail, the bottom and top of the positioning seat 7 are provided with limiting grooves, one side of the blocking rack 10 and the top of the limiting rack 11 are fixedly connected with linear sliders, and the two linear sliders are slidably connected inside the two limiting grooves respectively. Through the structural cooperation of the limiting grooves and the linear sliders, the displacement of the blocking rack 10 and the limiting rack 11 can be supported to avoid separation from the driving bevel gear 9;

[0028] Furthermore, one end of the positioning frame 15 is fixedly connected to a contact pad, and an anti-skid pattern is provided on the outside of the contact pad. The contact pad with the anti-skid pattern can effectively increase the friction between the positioning frame 15 and the bar material when in contact, thereby preventing the bar material from being displaced.

[0029] Example 2

[0030] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a feeding component 6;

[0031] In this embodiment, the feeding assembly 6 includes a transmission screw 18, a transmission motor 19 and a displacement frame 20. The transmission frame 5 is internally rotatably connected with the transmission screw 18, one end of the transmission frame 5 is fixedly connected with the transmission motor 19, and the output end of the transmission motor 19 is fixedly connected with the transmission screw 18, the outer side of the transmission screw 18 is threadedly connected with the displacement frame 20, the bottom end of the displacement frame 20 is fixedly connected with a hydraulic cylinder A21, the output end of the hydraulic cylinder A21 is fixedly connected with a bearing seat 22, one side of the top of the bearing seat 22 is fixedly connected with a hydraulic cylinder B23, and the output end of the hydraulic cylinder B23 is fixedly connected with a positioning plate 24;

[0032] In summary, the hydraulic cylinder B23 is started to push the positioning plate 24 to contact the bar material to achieve the positioning of the bar material, and the transmission motor 19 is started to drive the transmission screw 18 to rotate, and the transmission screw 18 is connected with the displacement frame 20, so that the displacement frame 20 is displaced along the transmission screw 18 until the bar material reaches the chuck of the machine tool body 1, and then the hydraulic cylinder A21 is started to push the bearing seat 22 to displace and push the bar material into the chuck;

[0033] Among them, a linear slide rod is fixedly connected to the inside of the transmission frame 5, a through hole and a threaded hole are opened at the top of the displacement frame 20, and there is a clearance fit between the linear slide rod and the through hole. The transmission screw 18 is connected inside the threaded hole. Through the setting of the linear slide rod, the displacement of the displacement frame 20 can be guided to prevent the displacement frame 20 from rotating with the transmission screw 18.

[0034] A specific application of the above two embodiments is that the bars to be processed are first placed into the storage box 3 in sequence, and the lowest bar will be carried by the blocking frame 12. When it is necessary to unload the bar, the driving motor 8 drives the driving bevel gear 9 to rotate, so that the driving bevel gear 9 simultaneously moves the blocking rack 10 and the limit rack 11 to drive the blocking rack 10 and the limit rack 11 to move toward each other. The displacement of the blocking rack 10 will gradually release the blocking of the bottom end of the storage box 3 by the blocking frame 12. The limiting rack 11 drives the positioning frame 15 to contact the second bar material to position it. When the blocking frame 12 releases the blocking of the material storage box 3, the bar material above the blocking frame 12 will pass through the bottom of the material storage box 3 and fall into the inner side of the bearing seat 22. The second bar material will not fall because it is positioned by the positioning frame 15. Subsequently, the driving motor 8 is reversely started to cause the blocking frame 12 to block the material storage box 3 while the positioning frame 15 is away from the bar material. Then the bar material can fall to the top of the blocking frame 12 and wait for unloading.

[0035] The bar material that falls into the inner side of the supporting seat 22 is positioned by starting the hydraulic cylinder B23 to push the positioning plate 24 to contact the bar material. At the same time, the transmission motor 19 is started to drive the transmission screw 18 to rotate, and the transmission screw 18 is connected with the displacement frame 20, so that the displacement frame 20 is displaced along the transmission screw 18 until the bar material reaches the chuck of the machine tool body 1. Then the hydraulic cylinder A21 is started to push the supporting seat 22 to displace the bar material, and the bar material is pushed into the chuck to realize feeding.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
