Description

Technical Field

[0001] The utility model relates to the technical field of screw fastening machines, in particular to a screw fastening machine capable of adjusting an adaptability range. Background Art

[0002] Screw tightening machines are devices used to automatically tighten screws or bolts, usually used in industrial production lines. They can greatly improve production efficiency and reduce labor costs while ensuring the quality and consistency of screw or bolt tightening.

[0003] For example, a screw tightening machine capable of adjusting the adaptability range disclosed in the authorization announcement number CN213560965U has an operating platform, a connecting rod and a mounting plate. The top of the operating platform is provided with a mounting groove, and a fixing device is installed on the top of the mounting groove. The connecting rod is installed on the top of the operating platform, and a cross bar is installed on the top of the connecting rod. A sliding groove is provided on one side of the cross bar, and an adjustment device is installed inside the cross bar. After adopting the above technical solution, the beneficial effect of the utility model is as follows: when the workpiece needs to be assembled, the workpiece to be assembled is placed on the fixing device, the pressing block is squeezed to move downward, and the elastic member is contracted, driving the transmission arm to move obliquely upward, so that the clamping arm moves closer to the middle to clamp the workpiece, thereby facilitating the fixing of the assembled workpiece.

[0004] Although the above patent can facilitate the fixation of the assembled workpiece, due to the inclined angle of the nail feeding tube, when the screw slides from the nail feeding tube to the bottom of the cutter head body, it may tilt inside the guide tube, and it cannot be guaranteed that each screw can maintain the same vertical angle with the cutter head body when loading.

[0025] like Figure 1-5 As shown, a technical solution provided by the utility model:

[0026] A screw fastening machine capable of adjusting the adaptability range comprises a workbench 1, an adjusting mechanism is arranged at the top of the workbench 1, the adjusting mechanism comprises an X-axis servo slide module 6, the X-axis servo slide module 6 is arranged at the middle of the top of the workbench 1, a Y-axis servo slide module 7 is arranged at the upper end of the X-axis servo slide module 6, an electric chuck 8 is arranged at the top of the Y-axis servo slide module 7, frames 2 are symmetrically arranged on both sides of the workbench 1, first electric push rods 3 are arranged on the inner sides of the middle parts of the two frames 2, and lifting frames 4 are arranged at the output shaft ends of the two first electric push rods 3;

[0027] In this embodiment, during operation, the workpiece that needs to be screwed is clamped and fixed by the electric chuck 8, and then the horizontal angle of the electric chuck 8 is adjusted by the X-axis servo slide module 6 and the Y-axis servo slide module 7 according to the position where the screws need to be screwed on the workpiece, so that it is convenient to adapt to different workpieces for screwing.

[0028] like Figure 2 and Figure 4 As shown, a mounting seat 5 is arranged at the top of one side of the lifting frame 4, and a mounting mechanism is arranged on the other side of the mounting seat 5, and the mounting mechanism includes a second electric push rod 9, and a motor 10 is fixedly installed on the output shaft of the second electric push rod 9, and a magnetic cutter head 11 is arranged at the output shaft end of the motor 10, and a guide groove 12 is opened in the middle of the lifting frame 4, and a material box 13 is movably installed in the middle of the guide groove 12, and a plurality of nail grooves 14 are arranged side by side in the middle of the material box 13;

[0029] In this embodiment, after the workpiece is clamped and the position is adjusted, the second electric push rod 9 is started, and the second electric push rod 9 drives the motor 10 to descend. After the motor 10 descends, it drives the magnetic cutter head 11 to insert and magnetically adsorb the screw inside the nail groove 14, and then the fourth electric push rod 19 is started, and the fourth electric push rod 19 retracts the through groove 15 under the nail groove 14, and then the first electric push rod 3 and the motor 10 are started. The first electric push rod 3 controls the lifting frame 4 and the mounting seat 5 to descend, and controls the magnetic cutter head 11 through the motor 10 to drive the screw to be twisted into the specified position on the workpiece, so that when screwing, positioning can be convenient and quick.

[0030] like Figure 4 As shown, a positioning mechanism is provided in the middle of the lifting frame 4, and the positioning mechanism includes a through slot 15. The lifting frame 4 is located in the middle of the guide slot 12 and penetrates through the through slot 15. A third electric push rod 16 is provided inside the left side of the guide slot 12.

[0033] In this embodiment, a blocking plate 20 is installed below the lifting frame 4 through a fourth electric push rod 19 , so that when the magnetic cutter head 11 is inserted and the screw is magnetically attracted, the screw will not fall from below the through slot 15 under pressure.

[0034] Working principle: During operation, the workpiece to be screwed is clamped and fixed by the electric chuck 8, and then the horizontal angle of the electric chuck 8 is adjusted by the X-axis servo slide module 6 and the Y-axis servo slide module 7 according to the position of the workpiece where the screws need to be screwed, so that it is convenient to adapt to different workpieces for screwing; when the workpiece is clamped and the position is adjusted, the second electric push rod 9 is started, and the second electric push rod 9 drives the motor 10 to descend. After the motor 10 descends, it drives the magnetic cutter head 11 to insert and magnetically absorb the screws inside the nail groove 14, and then the fourth electric push rod is started. Rod 19, the fourth electric push rod 19 retracts the through slot 15 below the nail slot 14, and then starts the first electric push rod 3 and the motor 10. The first electric push rod 3 controls the lifting frame 4 and the mounting seat 5 to descend, and controls the magnetic cutter head 11 through the motor 10 to drive the screw to be twisted into the specified position on the workpiece. After the first screw is pushed in, the third electric push rod 16 is started, and the third electric push rod 16 pushes the material box 13 forward.
