[0026] During use, the screw 3 is placed in the discharge funnel 2, and the screw 3 is sorted and arranged through the discharge funnel 2. Then the first electric push rod 4 pushes the first push rod 5, and the screw 3 is pushed out by the first push rod 5, and then clamped by the clamping assembly 6. Then the first drive motor 8 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the bracket 10 to rotate, and moves the bracket 10 to the bottom of the screw 3 to support the screw 3. Then, the second drive motor 13 drives the chamfering block 14 to rotate, and chamfers the clamped and rotating screw 3.

[0027] The clamping assembly 6 includes a slide rod 601, a support ring 602, a T-block 603, a first cylinder 604, a clamping block 605 and an inclined groove 606. The slide rod 601 has two fixed connections at the front end of the discharge funnel 2, the support ring 602 is located at the front end of the discharge funnel 2 and slides on the slide rod 601, the T-block 603 is fixedly connected to the front end of the support ring 602, the first cylinder 604 has two fixed connections at the bottom of the front end of the T-block 603, the clamping block 605 has two movably mounted on the top of the base plate 1, the inclined groove 606 is opened at the top of the inclined groove 606, and the first cylinder 604 is located inside the inclined groove 606.

[0028] When in use, the control support ring 602 can slide on the slide rod 601, and the T-block 603 also moves with the support ring 602, while driving the first cylinder 604 to move together. At this time, through the inclined design of the inclined groove 606, the movement of the first cylinder 604 in the inclined groove 606 will be converted into a relative movement of the clamping block 605 in the horizontal direction, thereby achieving the clamping of the screw 3.

[0029] The clamping assembly 6 also includes a second push rod 607, a support block 608 and a spring 609. The second push rod 607 has two fixed connections to the outer wall of the first push rod 5 and is located on both sides of the discharge funnel 2. The support block 608 has two fixed connections to the rear end of the outer wall of the support ring 602. The spring 609 is sleeved on the outer wall of the slide rod 601. The T-block 603 is fixedly connected between the discharge funnel 2 and the support ring 602. The position of the second push rod 607 corresponds to that of the support block 608.

[0030] During use, when the first push rod 5 pushes the screw 3 forward, the second push rod 607 also moves forward. When the second push rod 607 contacts the support block 608, it will push the support block 608, and then push the support ring 602 to slide forward on the slide rod 601. The spring 609 plays a resetting role in this process. When the first push rod 5 moves backward, after the thrust disappears, the spring 609 can make the support ring 602 return to its initial position, thereby loosening the screw 3.

[0031] The clamping assembly 6 further includes a second cylinder 610 and a transverse groove 611 . The second cylinders 610 are fixedly connected to the top of the base plate 1 . The transverse groove 611 is opened at the bottom of the clamping block 605 . The second cylinder 610 is located inside the transverse groove 611 .

[0032] When in use, the second cylinder 610 is located inside the transverse groove 611. This design limits the vertical movement of the clamping block 605, so that the clamping block 605 can only make relative movement in the horizontal direction, ensuring the stability and accuracy of the clamping action, and preventing the clamping block 605 from shaking up and down during operation, thereby ensuring stable clamping of the screw 3.

[0033] A discharge chute 201 is provided inside the discharge hopper 2 , and the screws 3 can be arranged vertically inside the discharge chute 201 .

[0034] The discharge chute 201 is designed to arrange the screws 3 in an orderly manner, to facilitate the discharge of the screws 3 and to facilitate subsequent clamping and processing operations.

[0035] The outer wall of the discharge funnel 2 is fixedly connected with an ear plate 202 . The ear plate 202 has two fixed connections on both sides of the outer wall of the discharge funnel 2 . The second push rod 607 is located inside the ear plate 202 .

[0036] When in use, the ear plate 202 can provide installation and guiding space for the second push rod 607, ensuring that the second push rod 607 can only perform linear motion in the horizontal direction, thereby ensuring that it can accurately push the support block 608.

[0037] A slot 101 is defined inside the bottom plate 1 , and the slot 101 is located at the bottom of the clamping assembly 6 .

[0038] After the chamfering is completed, the screw 3 can fall out through the slot 101 and be discharged.

[0039] A second electric push rod 11 is fixedly installed on the top of the base plate 1, a second mounting block 12 is fixedly installed on the rear end of the second electric push rod 11, and a second drive motor 13 is located inside the second mounting block 12. The top of the base plate 1 is fixedly connected to the first mounting block 7, and the first drive motor 8 is fixedly installed inside the first mounting block 7.

[0040] The second electric push rod 11 controls the extension and retraction of the second drive motor 13 through the second mounting block 12, and can accurately adjust the positions of the second drive motor 13 and the chamfering block 14; the first mounting block 7 is used to fix the first drive motor 8 to ensure the stability of the first drive motor 8 during operation, so that it can stably drive the rotating rod 9 to rotate.

[0041] Working principle: When in use, the screw 3 is placed in the discharge funnel 2, the screw 3 is sorted and arranged through the discharge funnel 2, and then the first electric push rod 4 pushes the first push rod 5, and then the first push rod 5 pushes the screw 3 out.

[0042] When the first push rod 5 pushes the screw 3 forward, the second push rod 607 also moves forward. When the second push rod 607 contacts the support block 608, it will push the support block 608, and then push the support ring 602 to slide forward on the slide rod 601. At the same time, the T-block 603 also moves with the support ring 602, and at the same time drives the first cylinder 604 to move together. At this time, through the inclined design of the inclined groove 606, the movement of the first cylinder 604 in the inclined groove 606 will be converted into relative movement of the clamping block 605 in the horizontal direction, thereby achieving clamping of the screw 3. At the same time, the second cylinder 610 is located inside the transverse groove 611. This design limits the movement of the clamping block 605 in the vertical direction, so that the clamping block 605 can only move relative to the horizontal direction, ensuring the stability and accuracy of the clamping action, and preventing the clamping block 605 from shaking up and down during work, thereby ensuring stable clamping of the screw 3.

[0043] Then the first drive motor 8 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the bracket 10 to rotate, moving the bracket 10 to the bottom of the screw 3 to support the screw 3. Then, the second drive motor 13 drives the chamfering block 14 to rotate, and chamfers the clamped and rotating screw 3.

[0044] After the processing is completed, when the first push rod 5 moves backward, the spring 609 can return the support ring 602 to the initial position, thereby loosening the screw rod 3, and then the screw rod 3 can fall out through the slot 101.

[0045] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments.
