Specific implementation mode

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a positioning and punching device for processing a yarn guide plate includes a workbench 1. A fixed shaft 3 protruding upward is fixedly connected to the top of the workbench 1, and a downwardly concave sliding groove 2 is formed in the top of the workbench 1. A positioning and pressing mechanism penetrating through the sliding groove 2 and extending above the workbench 1 is installed at the bottom of the workbench 1. The positioning and pressing mechanism is used to press or release the pressing on the two straight plate parts of the yarn guide plate 5; a pushing mechanism connected to the positioning and pressing mechanism is installed at the bottom of the workbench 1. The positioning and pressing mechanism in the reset state is used to remove the downward pressure applied to the pushing mechanism, so as to realize the upward reset of the pushing mechanism; the upward reset pushing mechanism is used to push the punched yarn guide plate 5 upward, facilitating the removal of the processed yarn guide plate 5.

[0022] In this embodiment: First, place the arc of the yarn guide plate 5 on the outer periphery of the fixed shaft 3, and then start the positioning press mechanism. At this time, the jacking mechanism is in the reset state. During the movement of the positioning and moving mechanism, the jacking mechanism is pressed down to the lowest position until the positioning and moving mechanism presses the straight plate part of the yarn guide plate 5. At this time, through three-point positioning, the yarn guide plate 5 can be positioned and clamped at the preset position.

[0023] Please pay special attention to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the positioning and pressing mechanism includes a sliding block 6 slidably connected to the inner cavity of the sliding groove 2. A positioning block 4 is fixedly connected to the top of the sliding block 6. A moving plate 7 is fixedly connected to one end of the sliding block 6 located below the workbench 1. Two fixed ears 8 are fixedly connected to the bottom end of the workbench 1. A guiding shaft 11 is fixedly connected between the two fixed ears 8. A moving ear 9 fixedly connected to the bottom end of the moving plate 7 is slidably connected to the outer wall of the guiding shaft 11. A first spring 10 is fixedly connected between the moving ear 9 and one of the fixed ears 8.

[0024] In this embodiment: By starting the movement of the moving plate 7 in the reset state, the moving plate 7 drives the moving ear 9 to move, and the moving ear 9 squeezes the first spring 10. At this time, the first spring 10 is compressed. The moving moving plate 7 drives the sliding block 6 to slide along the sliding groove 2, and the sliding block 6 drives the positioning block 4 at its top to move. During the movement of the two positioning blocks 4, the yarn guiding plate 5 that is placed offset is corrected, thus achieving the effect of positioning and clamping.

[0025] Please refer specifically to Figure 2 , a tooth block 12 protruding outward is integrally formed on one side of the sliding groove 2, a gear 14 is engaged with the outer periphery of the tooth block 12, and a forward and reverse motor 13 connected to the gear 14 is installed at the bottom end of the workbench 1 through a fixing frame.

[0026] In this embodiment: By starting the forward and reverse motor 13, the forward and reverse motor 13 drives the gear 14 at its output end to rotate, and the rotating gear 14 drives the moving plate 7 to move through the tooth block 12;

[0027] By controlling the rotation direction of the forward and reverse motor 13, the purpose of moving the moving plate 7 in different directions can be achieved.

[0028] Please refer specifically to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the pushing mechanism includes a jacking column 16 that penetrates from below the workbench 1 to above the workbench 1. The bottom ends of a plurality of jacking columns 16 are all connected to the same lifting plate 15. A second spring 17 is fixedly connected to the top of the lifting plate 15, and the top of the second spring 17 is fixedly connected to the bottom end of the workbench 1. The pushing mechanism also includes a synchronous plate 18 fixedly connected to the inner side wall of the moving plate 7. An extrusion inclined surface 19 is formed at the bottom end of the synchronous plate 18, and the extrusion inclined surface 19 is located at the connection position between the narrow part and the wide part of the synchronous plate 18. A groove is formed at the top of the lifting plate 15, and the bottom of the inner wall of the groove coincides with the extrusion inclined surface 19.

[0029] In this embodiment: When the moving plate 7 moves in the pressing direction, the moving plate 7 pushes the synchronous plate 18 to move synchronously. The moving synchronous plate 18 drives the extrusion inclined surface 19 at its bottom end to move synchronously. When the extrusion inclined surface 19 contacts the bottom end of the inner wall of the groove, at this time, the extrusion inclined surface 19 presses down the lifting plate 15 through the groove. At this time, the jacking column 16 in the reset state moves downward synchronously with the lifting plate 15. During the downward movement of the jacking column 16, the yarn guiding plate 5 moves downward accordingly until the bottom end surface of the yarn guiding plate 5 contacts the top end surface of the workbench 1;

[0030] After the punching is completed, when the moving plate 7 moves in the direction of releasing the pressing, the synchronous plate 18 moves in the opposite direction accordingly, and the extrusion inclined surface 19 moves accordingly. At this time, the inner wall bottom end of the groove is no longer extruded by the extrusion inclined surface 19, and the second spring 17 resets. The reset second spring 17 pulls the lifting plate 15 to move upward, and the lifting plate 15 synchronously drives a plurality of jacking columns 16 to move upward. The upward moving jacking columns 16 jack up the yarn guiding plate 5 after punching, realizing the separation of the bottom of the yarn guiding plate 5 from the top surface of the workbench 1, which facilitates the staff to take away the punched yarn guiding plate 5.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
