Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically to a feeding mechanism for screw processing. Background Technology

[0002] During screw manufacturing, a Phillips head or slotted head needs to be cut into the top of the screw to mate with a corresponding screwdriver for installation. Currently, the Phillips head or slotted head on screws is formed through casting and cold heading. The former involves setting corresponding protrusions in the mold during screw forming, allowing the Phillips head or slotted head to be formed simultaneously with the screw. The latter involves cold heading the top of the screw after forming. Existing cold heading devices for screws use positioning components to position the screw before cutting. After cutting, the screw is removed, and another batch of screws is fed in for cutting. This loading method is slow and affects screw production efficiency.

[0003] To address the aforementioned technical problems, this application proposes a feeding mechanism for screw processing. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figure 1 and attached Figure 2 As shown, a screw feeding mechanism includes a frame 1. The frame 1 has an upper mounting groove 3. A rectangular frame 4 is rotatably mounted inside the mounting groove 3. A drive assembly is mounted at the bottom of the mounting groove 3. The drive assembly includes a motor 6. A connecting block 7 is mounted on the shaft end of the motor 6. The connecting block 7 is connected to the rectangular frame 4 by bolts. The bottom of the mounting groove 3 has a groove 5 for mounting the motor 6. A controller 8 connected to the motor 6 is mounted on the front of the frame 1. The controller 8 starts the motor 6, and the motor 6 drives the rectangular frame 4 to rotate inside the mounting groove 3.

[0026] As attached Figure 3 and attached Figure 5As shown, fixed clamping frames 9 are fixedly installed on the inner side of the upper part of the four side walls of the rectangular frame 4, and movable clamping frames 11 are slidably installed on the outer side of the upper part of the four side walls of the rectangular frame 4. The fixed clamping frames 9 and the movable clamping frames 11 are provided with corresponding C-shaped grooves 10 and 12 on the side close to each other. Screws are inserted between C-shaped grooves 10 and 12. A position adjustment component that drives the movable clamping frame 11 to move laterally is installed on the side wall of the rectangular frame 4. The position adjustment component includes a moving plate 13 and a threaded shaft 15. The moving plate 13 is installed on the outer side of the movable clamping frame 11 by bolts. The threaded shaft 15 passes through the moving plate 13 with threads. The outer wall of the rectangular frame 4 is provided with a U-shaped groove 14. One end of the threaded shaft 15 is rotatably installed to the bottom of the U-shaped groove 14, and the other end is equipped with a handwheel 16. The handwheel 16 drives the threaded shaft 15 to rotate.

[0027] The specific usage method is as follows:

[0028] The operator, positioned at the front of frame 1, inserts the screws to be processed between C-slot 10 and C-slot 2 12. Turning handwheel 16 rotates the threaded shaft 15, which in turn moves the movable plate 13, causing the movable clamping frame 11 to move towards the fixed clamping frame 9 on the upper side of the rectangular frame 4. The fixed clamping frame 9 contacts the movable clamping frame 11, and C-slot 10 and C-slot 2 12 clamp and position the screws. The controller 8 starts motor 6, which rotates the rectangular frame 4 90° inside the mounting slot 3. Screws are then placed onto the upper front wall of the rectangular frame 4 in the same manner. The rectangular frame 4 continues to rotate 90°, delivering a row of positioned screws to the underside of the grooving assembly. The grooving assembly moves laterally to groove the tops of the screws sequentially. The motor 6 continues to rotate the rectangular frame 4, delivering the grooved screws. When the screws reach the front, the operator unloads and reloads them, ensuring continuous feeding.

[0029] Example 2

[0030] Based on Example 1, please refer to the appendix. Figure 3 and attached Figure 4The rectangular frame 4 has pusher assemblies installed on the lower sides of its four side walls. Each pusher assembly includes four sets of push plates 17, located below the side walls of the rectangular frame 4. A strip groove 18 is provided on the lower side of the side wall of the rectangular frame 4, and the push plates 17 slide up and down within the strip groove 18. A push rod 19 is fixedly installed on one side above the push plate 17, sliding through the rectangular frame 4. The rectangular frame 4 has through holes that communicate with C-shaped groove 10 and C-shaped groove 12. The strip groove 18 is connected to the through hole on the rectangular frame 4. The lower end of the screw passes through the space between the C-shaped groove 10 and the C-shaped groove 12 and the through hole on the rectangular frame 4. When discharging the screw, the push rod 19 is pulled upward. The push rod 19 drives the push plate 17 to slide upward inside the strip groove 18. The push plate 17 pushes multiple sets of screws upward to facilitate screw discharge. After discharge, the push rod 19 is pushed downward. The push rod 19 pushes the push plate 17 downward, which will not affect screw loading.

[0031] As attached Figure 2 As shown, a mounting box 2 for the slotting assembly is installed on the top of the frame 1. An electric telescopic rod 20 is installed through the front of the mounting box 2. A transparent baffle 21 is installed at the lower end of the electric telescopic rod 20. The electric telescopic rod 20 pushes the transparent baffle 21 downward. After the screw moves to the lower side of the slotting assembly, the electric telescopic rod 20 is activated, which pushes the transparent baffle 21 downward and inserts it into the side of the fixed clamping frame 9 away from the movable clamping frame 11. This blocks the chips generated during cutting and prevents the chips from splashing onto the workers loading and unloading, thus preventing injury to the workers.
