Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0034] See also Figure 1-Figure 8 The utility model proposes a material conveying mechanism of a chamfering machine, including an operating table 1, on which a chamfering device 2, a collecting box 3, a material discharge mechanism 4 and a feeding device 5 are arranged.

[0036] Further, the base 56 is slidably connected with a clamping claw 561, the clamping claw 561 is slidably connected with an elastic pressure plate 5610 and a clamping rod 5611, the outer wall of the clamping rod 5611 is fixedly connected with a spring 1 5612, one end of the spring 1 5612 away from the clamping rod 5611 is fixedly connected with the inner wall of the clamping claw 561, the clamping claw 561 is penetrated by a guide rod 562 and is slidably connected with the guide rod 562, the guide rod 562 is fixedly connected with the inner wall of the base 56, the outer wall of the clamping claw 561 is fixedly connected with a spring 2 563, and the base 56 is provided with a clamping groove 564;

[0037] like Figure 3 and Figure 6 As shown, when the clamping jaw 561 clamps the tube body 432 under the drive of the hydraulic cylinder 2 55, the groove 431 at the material transport plate 43 will squeeze the clamping jaw 561, as shown in FIG. Figure 6As shown, in this state, the clamping rod 5611 is inside the clamping jaw 561, and the spring 1 5612 is in an elastic deformation state. When the clamping jaw 561 is squeezed by the groove 431, the two groups of clamping jaws 561 will move toward the middle, and the spring 2 563 will undergo elastic deformation. When the clamping jaw 561 clamps the tube body 432, the clamping rod 5611 is just stuck in the clamping groove 564, thereby completing the limitation of the clamping jaw 561.

[0038] Further, the card slot 564 is slidably connected to a push rod 565, the outer wall of the push rod 565 is fixedly connected to one end of a spring three 566, the other end of the spring three 566 is fixedly connected to the inner wall of the base 56, the base 56 is slidably connected to a slide bar 567, the outer wall of the slide bar 567 is fixedly connected to a spring five 568, the end of the spring five 568 away from the slide bar 567 is fixedly connected to the inner wall of the base 56, the slide bar 567 is slidably connected to a slider 5671, the outer wall of the slider 5671 is fixedly connected to a spring four 5672, the end of the spring four 5672 away from the slider 5671 is fixedly connected to the inner wall of the slider 567, and the base 56 is fixedly connected to an extrusion rod 569;

[0039] like Figure 4 and Figure 8 As shown, when the clamping jaw 561 clamps the tube body 432 to the chamfering device 2, the slider 5671 will contact the elastic block 571 and squeeze the elastic block 571. During this process, the slider 5671 and the elastic block 571 move simultaneously until the slider 5671 is separated from the elastic block 571. When the chamfering of the tube body 432 is completed, the clamping jaw 561 clamps the tube body 432 and returns under the drive of the motor 52. During this process, the elastic block 571 will contact the slider 5671 again. The difference from the previous time is that the elastic block 571 will squeeze the slider 5671 at this time. Figure 7 As shown, when the slider 5671 is squeezed by the elastic block 571, the slider 567 slides. During this process, the slider 567 squeezes the push rod 565, and the push rod 565 squeezes the clamping rod 5611, so that the clamping rod 5611 moves into the inside of the clamping jaw 561. It should be noted that when the bottom surface of the slider 567 completely overlaps with the push rod 565, the clamping rod 5611 just completely enters the inside of the clamping jaw 561 under the action of the push rod 565, so that the limit of the clamping jaw 561 is released, and then the clamping jaw 561 returns to its original position under the elastic force of the spring 563, thereby releasing the clamping of the tube body 432 and achieving the purpose of material unloading.

[0040] During this process, the slider 5671 is squeezed by the slide bar 567, so that the slider 5671 gradually moves downward. When the clamping of the tube 432 is released, the elastic block 571 contacts the inclined surface of the slider 5671. At this time, the elastic block 571 applies a downward force to the slider 5671, so that the slider 5671 moves downward until it is separated from the elastic block 571.

[0041] In the present invention, when in use, firstly, multiple groups of tube bodies 432 are placed inside the lower hopper 41, and then the tube bodies 432 enter the grooves 431 through the lower material port 411, and then the hydraulic cylinder 1 42 is started to transport the tube bodies 432 to the bottom of the clamping jaws 561, and then the hydraulic cylinder 2 55 is started to make the clamping jaws 561 move downward, and in this process, the grooves 431 squeeze the clamping jaws 561, so that the clamping jaws 561 move toward the middle, and when the clamping jaws 561 clamp the tube bodies 432, the clamping rods 5611 are just stuck in the clamping grooves 564, thereby completing the position limiting of the clamping jaws 561, and then the hydraulic cylinder 2 55 is started to make the clamping jaws 561 return to the original position, and then the motor 52 is started, and the reciprocating screw 53 The transmission of the clamping jaws 561 drives the tube body 432 to move toward the chamfering device 2. During this process, the slider 5671 and the elastic block 571 squeeze each other until they are separated from each other. After the tube body 432 is polished by the chamfering device 2, the clamping jaws 561 clamp the tube body 432 for return under the drive of the motor 52. During this process, the elastic block 571 will contact the slider 5671 again. At this time, the elastic block 571 will squeeze the slider 5671, so that the sliding rod 567 will squeeze the ejector rod 565, thereby ejecting the clamping rod 5611 from the clamping groove 564, thereby contacting the limit of the clamping jaws 561. At this time, the clamping jaws 561 return to their original positions under the action of the spring 2 563, thereby releasing the clamping of the tube body 432.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
