Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 6 As shown, the technical solution provided by the present utility model:

[0024] A screw intelligent cutting device for manufacturing hardware products, including a cutting machine base 1. One end of the cutting machine base 1 is rotatably connected with multiple clamping seat control shafts 2. A limit plate 3 is fixedly connected to the surface of the multiple clamping seat control shafts 2. A clamping seat 4 is slidably connected to the limit plate 3. The limit plate 3 is used to limit the linear sliding of the clamping seat 4, support the clamping seat 4 while limiting, and connect the clamping seat 4 and the multiple clamping seat control shafts 2. As Figure 1As shown, a plurality of components such as a limit plate 3 and a clamping seat 4 are provided, and are distributed in a circular array on a plurality of clamping seat control shafts 2. The clamping seat 4 is rotatably connected with a worm gear 5 and a worm gear shaft 6, respectively. The surface of the worm gear shaft 6 is fixedly connected with a clamping arc block 7 through a connecting plate. The surface of the cutting machine seat 1 is fixedly connected with an opening and closing rack 8. The clamping seat 4 is provided with a synchronous cutting auxiliary device 9, and the cutting machine seat 1 is provided with a self-locking drive device 10. A cutting motor 11 is installed at the end of the cutting machine base 1, and a cutting blade 12 is clamped on the output shaft of the cutting motor 11. The cutting blade 12 is rotatably connected to the cutting machine base 1 at one end close to the cutting motor 11. The synchronous cutting auxiliary device 9 drives the worm gear 5 on the clamping seat 4 to move away from the cutting axis to engage the opening and closing rack 8 to achieve rotation. The worm gear 5 engages the clamping arc block 7 connected to the worm gear shaft 6 and rotates to open. After the screw is placed on the clamping seat 4, the synchronous cutting auxiliary device 9 controls the clamping seat 4 to reset, and the clamping arc block 7 rotates and merges to achieve the effect of clamping and positioning the screw. The self-locking drive device 10 is used to drive multiple clamping seats to control the rotating shaft 2 to rotate, so as to achieve the purpose of feeding and clamping multiple screws. The synchronous cutting auxiliary device 9 controls the screws on the multiple clamping seats 4 to move toward the cutting axis, and the synchronous cutting work is completed during the movement. The screws distributed in multiple circular arrays are synchronously moved and cut, and one cutting knife synchronously cuts multiple screws, thereby achieving the purpose of improving the screw cutting efficiency.

[0025] In this embodiment, the synchronous cutting auxiliary device 9 includes a screw seat 91, the end of the screw seat 91 is fixedly connected to the clamping seat 4, the internal thread of the screw seat 91 is connected to a screw rod 92, the end of the screw rod 92 is fixedly connected to a bevel gear 93, and the surface of the bevel gear 93 is meshed with a bevel gear disk 94. By meshing a plurality of bevel gears 93 with one bevel gear disk 94, the purpose of driving the plurality of screw rods 92 to rotate is achieved, and then the purpose of synchronous movement of the plurality of clamping seats 4 is achieved. An adjusting motor 95 is clamped at the end of the bevel gear disk 94. The bevel gear disk 94 is driven by a motor to drive the bevel gear disk 94 to drive the plurality of clamping seats 4 to move, which has an energy-saving effect and avoids the problems of increased cost and power consumption caused by multiple electric structures driving the plurality of clamping seats 4 to move. The surface of the screw 92 is rotatably connected with a fixed block 96 for supporting and positioning the screw 92 and limiting its rotation within the fixed block 96. The end of the fixed block 96 is fixedly connected to a plurality of clamp seat control shafts 2. The end of the screw 92 away from the bevel gear 93 is fixedly connected to a limiting block 97 for limiting the screw seat 91 threadedly connected to the screw 92 to prevent the screw seat 91 from detaching from the screw 92 due to excessive rotation of the adjustment motor 95. The end of the bevel gear disk 94 is rotatably connected to the end of a plurality of clamp seat control shafts 2, and the adjustment motor 95 is installed in the plurality of clamp seat control shafts 2.

[0026] Furthermore, the self-locking drive device 10 includes a drive motor 101, which is installed on the cutting machine base 1. The output shaft of the drive motor 101 is clamped with a driving worm 102, and the surface of the driving worm 102 is engaged with a driving worm gear 103. By connecting the worm and the worm gear on the motor output shaft, it is ensured that the motor can drive multiple clamping seat control shafts 2 to rotate while achieving angle self-locking. At the same time, the intermittent connection can prevent the pressure from being directly applied to the motor output shaft when the multiple clamping seat control shafts 2 are subjected to cutting forces, achieving the purpose of protecting the motor output shaft. A connecting rod 104 is fixedly connected inside the driving worm gear 103. The end of the connecting rod 104 is fixedly connected to the ends of the multiple clamping seat control shafts 2, and the surface of the connecting rod 104 is rotatably connected inside the cutting machine base 1.

[0027] Even further, the toothed worm 5 is composed of a combination of a gear and a worm. The toothed worm 5 is engaged with the surface of the worm gear shaft 6 through the worm. The gear is used to contact the opening and closing rack 8. During the movement of the toothed worm 5 along with the clamping seat 4, when it contacts the opening and closing rack 8, it rotates by means of meshing, achieving the purpose of driving the worm gear shaft 6 to rotate, and then controlling the clamping arc block 7 to open and close, and completing the feeding of the screw during the opening and closing.

[0028] When the intelligent screw cutting device for manufacturing hardware products of the present utility model is in use, by starting the adjusting motor 95, the output shaft of the adjusting motor 95 drives a plurality of bevel gears 93 distributed in a circular array thereon to rotate synchronously through the bevel gear disk 94. When the bevel gears 93 rotate, they drive the screw rods 92 fixedly connected to their ends to rotate. The screw rods 92 drive the screw seats 91, which are limited to perform linear sliding connection, to move through the principle of threaded connection. When the bevel gear disk 94 rotates forward, the screw seats 91 move away from the axis of the plurality of clamp seat control rotating shafts 2. The screw seats 91 drive the entire clamping seats 4 to move outward from the axis of the plurality of clamp seat control rotating shafts 2. During the movement, the internal tooth worm 5 of the clamping seat 4 located at the opening and closing rack 8 contacts and meshes with the opening and closing rack 8. The tooth worm 5 rotates within the clamping seat 4 and meshes with the worm gear shaft 6 to rotate. The worm gear shaft 6 drives the clamping arc block 7 to rotate through the connecting plate. The clamping arc block 7 rotates and unfolds on the clamping seat 4. When the clamping arc block 7 is fully unfolded, the screw can be placed at the screw groove of the clamping seat 4. After placement, the adjusting motor 95 is controlled to drive the bevel gear disk 94 to rotate in the reverse direction. The screw seats 91 drive the entire clamping seats 4 to move towards the axis of the plurality of clamp seat control rotating shafts 2. During the inward movement of the clamping seats 4, the tooth worm 5 meshes with the opening and closing rack 8 in the reverse direction and is forced to rotate in the reset direction. The tooth worm 5 meshes with the worm gear shaft 6 and drives the clamping arc block 7 on the connecting plate to rotate in the reset direction. The clamping arc block 7 gradually contacts and connects with the clamping seat 4 and performs the merging work thereon. The screw groove on the merged clamping arc block 7 connects to the surface of the screw, achieving the effect of clamping and fixing the screw by using the screw grooves in the clamping arc block 7 and the clamping seat 4, performing threaded fixation on the screw, and improving the stability during screw cutting; after the screw is loaded and clamped, by starting the driving motor 101 to drive the driving worm 102 meshed with the driving worm wheel 103 to rotate, the worm wheel drives the entire plurality of clamp seat control rotating shafts 2 to rotate through the connecting rod 104. By using the overall rotation of the plurality of clamp seat control rotating shafts 2, the components at each of the circularly arrayed clamping seats 4 are sequentially rotated to the opening and closing rack 8. Before each clamping seat 4 rotates to the rack and rotates again, by controlling the adjusting motor 95, the clamping arc block 7 on the clamping seat 4 performs the opening and closing operations, and the screw is loaded during the opening and closing process, thereby sequentially achieving the effects of sequentially loading and clamping the screws for each of the circularly arrayed clamping seats 4. The plurality of clamp seat control rotating shafts 2 clamp a plurality of screws and distribute them in a circular array, making it convenient for the cutting cutter disk 12 to perform synchronous cutting.After the screws are fed at multiple stations, the cutting motor 11 and the adjusting motor 95 are started synchronously. The adjusting motor 95 controls the conical gear disc 94 to continue rotating in the reverse direction. The screw base 91 drives the clamping seat 4 as a whole to continue moving towards the axis of the control rotating shaft 2 of multiple clamping seats. During the movement, the clamping seat 4 drives the internally clamped screws to move towards the control rotating shaft 2 of multiple clamping seats. During the inward movement of the screws, they contact the high-speed rotating cutting tool disc 12 for moving cutting. Multiple screws distributed in a circular array move and cut synchronously. One cutting tool disc 12 cuts multiple screws during cutting, thereby achieving the purpose of improving the screw cutting efficiency.

Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the embodiments of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the embodiments of the present invention.
