DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The utility model discloses a mechanical cutting auxiliary device, such as Figure 1-7 As shown, it is a preferred embodiment of the utility model, including a workbench 15 for placing a workpiece 13, a dust box 12, a side positioning mechanism for abutting the workpiece 13, a positioning and guiding mechanism, and a dust removing mechanism for sweeping the dust into the dust box 12; one side of the workbench 15 is connected to the dust box 12, and a side of the dust box 12 connected to the workbench 15 is provided with an opening for dust to enter; each of the four sides of the workbench 15 is provided with a side positioning mechanism; the positioning and guiding mechanism is arranged on a side of the workbench 15 connected to the dust box 12, and includes a first electric lifting rod 6 and a flip plate 1 rotatably connected thereto; the dust removing mechanism is fixedly connected to the dust box 12 or the workbench 15.

[0030] See also Figure 2-3 , Figure 6-7 The flip plate 1 of the positioning and guiding mechanism can be formed by connecting a long strip 21 and an inclined plate 22 to form an integral whole. The angle between the two is an obtuse angle, and an arc-shaped groove 23 is provided at the angle. There are two first electric lifting rods 6, and the bottom ends of the two first electric lifting rods 6 are arranged on the inner bottom surface of the dust box 12 or a fixed plate 14. A motor 4 is mounted on the top of one of the first electric lifting rods 6. The output end of the motor 4 is fixedly connected to a rotating shaft 3. The end of the rotating shaft 3 away from the motor 4 is rotatably connected to a first connecting block 5. The first connecting block 5 is mounted on the top of the other first electric lifting rod 6. The middle position of the rotating shaft 3 can be sleeved with a connecting shaft 2, and the connecting shaft 2 can be fixedly connected to the arc-shaped groove 23 at the center of the bottom surface of the flip plate 1. The two first electric lifting rods 6 can be completely symmetrical relative to the center of the dust box 12. The length of the flip plate 1 and the opening length of the dust box 12 are consistent with the side length of the workbench 15 connected to the dust box 12. The flipping process of the flip plate 1 includes two working states: see Figure 2The first working state is to position the workpiece 13 placed on the surface of the workbench 15. Specifically, the first electric lifting rod 6 drives the flip plate 1 to move up and down, so that the long strip 21 of the flip plate 1 presses against the workpiece 13 from the upper surface, thereby positioning the workpiece 13 up and down; see Figure 3 The second working state is to guide the debris on the workbench 15 or the workpiece 13. Specifically, the first electric lifting rod 6 drives the flip plate 1 to move up and down, and the motor 4 drives the flip plate 1 to rotate, so that the long strip 21 of the flip plate 1 is in contact with the side of the workbench 15 or the workpiece 13, and the inclined plate 22 of the flip plate 1 and the upper surface of the workbench 15 or the workpiece 13 form a slope toward the bottom of the dust box 12, which is convenient for the dust removal mechanism to remove the dust into the dust box.

[0031] See also Figure 1-5 , the side positioning mechanism can be composed of a first electric telescopic rod 16 and a positioning block 17. A fixed plate 14 is provided on each of the four sides of the workbench 15. One end of the first electric telescopic rod 16 is fixed on the fixed plate 14, and the other end is fixedly connected to the positioning block 17. The first electric telescopic rod 16 controls the positioning block 17 to push against the workpiece 13 through the telescopic action. The telescopic direction of the first electric telescopic rod 16 can be parallel to the upper surface of the workbench 15, but in this embodiment, in order to avoid mutual interference with the dust removal mechanism, the telescopic direction of the first electric telescopic rod 16 on the dust box 12 side is perpendicular to the upper surface of the workbench 15. Further, the fixed plates 14 on the two opposite sides of the workbench 15 that are not connected to the dust box 12 can be L-shaped, and a sliding rod 20 can be provided between the top ends thereof. A slider 19 is slidably connected to each end of the slider 20. The two sliders 19 can be centrally symmetrical. The two sliders 19 are respectively fixedly connected to the positioning blocks 17 of the side positioning mechanism connected to the fixed plate 14 below them by a connecting rope 18. In this embodiment, a hole is provided on the fixed plate 14, one end of the connecting rope 18 is connected to the slider 19, and the other end passes through the hole and is connected to the positioning block 17 at the output end of the first electric telescopic rod 16. Since the slide bar 20 and the fixed plate 14 are fixed relative to the workbench 15, the slide bar 19 fixedly connected to the positioning block 17 can slide smoothly on the slide bar 20 during the movement of the positioning block 17, thereby enhancing the positioning effect of the positioning block 17.

[0032] See also Figure 1-5, the dust removal mechanism may include a cleaning block 7, a second electric lifting rod 11 for controlling the vertical lifting of the cleaning block 7, and a second electric telescopic rod 9 for controlling the horizontal extension and retraction of the cleaning block 7. In the present embodiment, the dust removal mechanism is fixedly connected to the dust collecting box 12. Specifically, the fixed end of the second electric lifting rod 11 is fixedly connected to the inner top surface of the dust collecting box 12, and the output end thereof is fixedly connected to a second connecting block 10, the fixed end of the second electric telescopic rod 9 is fixedly connected to the second connecting block 10, the second electric telescopic rod 9 is in a vertical state with the second electric lifting rod 11, and the extension direction of the second electric telescopic rod 9 is toward the outside of the opening of the dust collecting box 12, the output end of the second electric telescopic rod 9 is fixedly connected to a third connecting block 8, and the lower end of the third connecting block 8 is connected to a cleaning block 7 of the same length as the flip plate 1 in the same direction.

[0033] The working principle of the utility model is as follows: put the workpiece 13 on the workbench 15, so that one side of the workpiece 13 is in the same horizontal plane as the side of the workbench 15 connected to the dust collecting box 12, and is centered as much as possible; the first electric lifting rod 6 drives the flip plate 1 to move up and down, so that the long strip 21 of the flip plate 1 presses against the workpiece 13 from the upper surface, thereby positioning the workpiece 13 up and down; the first electric telescopic rods 16 on the four sides of the workbench 15 control the positioning blocks 17 to push against the four sides of the workpiece 13 through telescopic action, thereby completing the positioning of the four sides of the workpiece 13, and then completing the positioning of the workpiece 13 in all aspects, which is convenient for the mechanical cutting parts to cut the workpiece 13, and can adapt to a variety of products of different sizes, thereby increasing its scope of use. The order of upper and lower positioning and side positioning can be interchanged. After the cutting is completed, the first electric lifting rod 6 drives the flip plate 1 to move up and down, and the motor 4 drives the flip plate 1 to rotate, so that the long strip 21 of the flip plate 1 fits with the side of the workpiece 13 and the inclined plate 22 of the flip plate 1 and the upper surface of the workpiece 13 form a slope toward the lower part of the dust box 12; the second electric telescopic rod 9 drives the cleaning block 7 to move to the end of the workpiece 13 farthest from the dust box 12, and then the second electric lifting rod 11 drives the cleaning block 7 to move downward until it fits with the workpiece 13, and then the second electric telescopic rod 9 is recovered, driving the cleaning block 7 and the dust to pass through the slope into the dust box 12, thereby completing the collection of dust, reducing the impact of dust on the internal components of the device, and ensuring the normal operation of the device. The workbench 15 is cleaned of dust in the same way.
