[0035] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A screw-locking device adaptable to different sizes, including a base 1.

[0036] A support plate 8 is fixedly installed at the middle of the right end of the base 1;

[0037] An arc-shaped fixing plate 9 is fixedly installed on the right end of the tray 8;

[0038] An electric screwdriver slot 10 is provided at the upper middle part of the arc-shaped fixing plate 9;

[0039] A screw through groove 11 is provided in the middle of the right end of the arc-shaped fixing plate 9; a screw channel tube 12 is fixedly installed on the screw through groove 11, and the screw through groove 11 is connected to the screw channel tube 12.

[0040] The screw channel tube 12 is externally connected to a hopper for storing screws;

[0041] The upper end of the base 1 is equipped with a lifting and buffering mechanism 2 for controlling the movement of the electric screwdriver 3; the electric screwdriver 3 is installed on the lifting and buffering mechanism 2.

[0042] The lifting and buffering mechanism 2 is equipped with a quick-release mechanism 4 for fixing the electric screwdriver 3 and enabling quick assembly and disassembly;

[0043] An oscillating screw locking mechanism 5 is installed on the arc-shaped fixing plate 9 to control the rotation of the screw gun 6 so that the positioning groove 7 on the screw gun 6 is aligned with the electric screwdriver through groove 10 or the screw through groove 11.

[0044] The screw gun 6 is mounted on the swing screw fastening mechanism 5, and a positioning groove 7 is provided in the middle of the screw gun 6; the upper end of the screw gun 6 is arc-shaped and slides in contact with the lower arc surface of the arc-shaped fixing plate 9.

[0045] The diameter of the positioning groove 7 is the same as the diameter of the electric screwdriver through groove 10 and the screw through groove 11;

[0046] In this invention, the swing-type screw fastening mechanism 5 rotates the screw gun 6, aligning the positioning groove 7 on the screw gun 6 with the screw through groove 11. At this point, screws of different sizes can enter the positioning groove 7 through the screw through groove 11. Once the screw enters the positioning groove 7, it is blocked by the bottom end of the screw gun 6. Then, the swing-type screw fastening mechanism 5 operates again, causing the screw gun 6 to rotate, aligning the positioning groove 7 on the screw gun 6 with the electric screwdriver through groove 10. At this time, the lifting and buffering mechanism 2 operates, causing the electric screwdriver 3 to move downwards. During this movement, the lower end of the electric screwdriver 3 enters the positioning groove through the electric screwdriver through groove 10. Within 7, until the lower end of the electric screwdriver 3 touches the upper end of the screw in the positioning groove 7, the electric screwdriver 3 then operates to achieve the screw locking effect; the swing screw locking mechanism 5 drives the screw gun 6 to swing, so that the positioning groove 7 can be aligned with the electric screwdriver through groove 10 or the screw through groove 11, so that screws of different sizes can fall directly into the positioning groove 7, avoiding the problem of material jamming and inability to discharge when feeding screws of different sizes, reducing the standby time of the equipment and improving the efficiency of material assembly; the quick-release mechanism 4 can realize the quick installation and removal of the electric screwdriver 3, further reducing the standby time of the equipment;

[0047] The swing-type screw fastening mechanism 5 includes a dual-axis cylinder 511, a rack 512, a drive gear 513, a rotating shaft 514, support plates 515, and limiting plates 516. The upper ends of the two support plates 515 are fixedly installed on the front and rear ends of the right side of the arc-shaped fixing plate 9. The middle part of the screw gun 6 is fixedly connected to the rotating shaft 514. The front and rear ends of the rotating shaft 514 are rotatably connected to the lower part of the two support plates 515 that are close to each other. The rear end of the rotating shaft 514 is fixedly connected to the drive gear 513. The dual-axis cylinder 511 is fixedly installed on the upper rear end of the arc-shaped fixing plate 9, and the output end of the dual-axis cylinder 511 is fixedly connected to the rack 512. The rack 512 is meshed with the drive gear 513.

[0048] The lifting and buffering mechanism 2 includes a cylinder 21, a slide rail 23, a slider 24, a support platform 25, and a buffer spring 26. The cylinder 21 is fixedly installed in the middle of the upper end of the base 1, and the output end of the cylinder 21 is fixedly connected to the upper end of the support platform 25. The slide rail 23 is fixedly installed in the right end of the base 1, and the slider 24 is slidably connected to the slide rail 23. The right end of the slider 24 is fixedly connected to the support platform 25. The upper end of the buffer spring 26 is fixedly connected to the lower end of the support platform 25, and the lower end of the buffer spring 26 is fixedly connected to the upper end of the support plate 8.

[0049] In this invention, when the screw-locking operation begins, the dual-axis cylinder 511 moves the rack 512 upwards, and the rack 512 drives the drive gear 513 to rotate, causing the screw gun 6 to rotate upwards around the rotating shaft 514 until the right end of the screw gun 6 touches the limiting plate 516 on the lower right side of the arc-shaped fixing plate 9. At this time, the positioning groove 7 on the screw gun 6 aligns with the screw through groove 11, and the screw can then pass through the screw through groove 11 into the positioning groove 7 and be stuck at the bottom of the screw gun 6. Subsequently, the dual-axis cylinder 511 works again to drive the rack 512 downwards, and the rack 512 drives the drive gear 513 to reverse, causing the screw gun 6 to rotate downwards around the rotating shaft 514 until the left end of the screw gun 6 touches the arc-shaped fixing plate 9. The limiting plate 516 at the left end of plate 9 is positioned so that the positioning groove 7 on the screw gun 6 is aligned with the through groove 10 of the electric screwdriver. Then, the cylinder 21 works, driving the support platform 25 to move downward along the slide rail 23, so that the electric screwdriver 3 moves downward with the support platform 25. When the support platform 25 moves downward, the buffer spring 26 acts as a buffer to prevent the support platform 25 from falling directly due to the failure of the cylinder 21. When the support platform 25 moves downward, the lower end of the electric screwdriver 3 will enter the positioning groove 7 through the screw through groove 11 until the lower end of the electric screwdriver 3 touches the upper end of the screw. At this time, the screw and the lower end of the electric screwdriver 3 are attracted. Then, the electric screwdriver 3 continues to move downward, driving the screw to extend out of the lower end of the screw gun 6. Then, the electric screwdriver 3 works to realize the screw fastening operation.

The fixed plate 41 is fixedly installed at the upper middle part of the support platform 25. The left end of the rotating plate 42 is hinged to the front and rear sides of the fixed plate 41. The rotating plate 42 has a through groove 43 in the middle. The inner bottom of the fixed plate 41 is rotatably connected to the locking plate 44. The locking plate 44 has the same shape as the through groove 43. The electric screwdriver 3 has a locking groove 45 on the left side of the middle part. The right end of the rotating plate 42 is engaged with the locking groove 45. The electric screwdriver 3 is fixedly installed at the right end of the support platform 25. The locking plate 44 passes through the through groove 43 and is engaged with the rotating plate 42.

[0051] In this invention, when locked, the locking plate 44 is in a vertically horizontal state, with its lower end fitting against the upper end of the rotating plate 42, preventing the rotating plate 42 from rotating. When the electric screwdriver 3 malfunctions and needs repair or replacement, the locking plate 44 is rotated to become horizontally horizontal. At this time, the rotating plate 42 is pulled upward, causing the through groove 43 in the middle of the rotating plate 42 to pass through the rotating plate 42, and the right end of the rotating plate 42 to leave the locking groove 45. Then the electric screwdriver 3 can be disassembled.

[0052] The above 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.
