Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 、 Figure 2 and Figure 3 The present invention provides an embodiment of a novel sheet metal processing positioning auxiliary device, comprising a base plate 1, a fixing frame 6 is fixedly connected to the top rear side of the base plate 1, an electric push rod 13 is fixedly connected to the inner middle upper part of the fixing frame 6, one end of the electric push rod 13 is fixedly connected to a connecting bar 12, and the left and right sides of the bottom of the connecting bar 12 are fixedly connected to a sawtooth bar 11, the left and right ends of the inner rear side of the fixing frame 6 are rotatably connected to gears 9, the two sawtooth bars 11 are respectively meshed with the corresponding gears 9, the front side of the gear 9 is fixedly connected to an elliptical block 10, and the left and right sides of the top wall of the base plate 1 are fixedly connected to an arc frame 8 , the bottom of the arc frame 8 is fixedly connected with a spring 7, the end of the spring 7 is fixedly connected with an arc-shaped slot block 14, the front side of the arc-shaped slot block 14 is fixedly connected with a pressure strip 15, the top front side of the bottom plate 1 is installed with a positioning mold 3, and the left side of the bottom plate 1 is installed with a cleaning mechanism 2, which is used to clean the processing debris; the top wall of the bottom plate 1 is equidistantly fixed with a plurality of slide rails 16, and the left and right sides of the arc-shaped slot block 14 are fixedly connected with sliders 17, and the plurality of sliders 17 are respectively slidably connected to the corresponding slide rails 16; the middle part of the top wall of the positioning mold 3 is provided with an anti-slip groove 4, and the four corners of the top wall of the positioning mold 3 are provided with positioning holes 5;

[0031] Specifically, the sheet metal is placed on the positioning mold 3; the surface of this mold is engraved with anti-slip grooves 4, which are intended to prevent the sheet metal from sliding or displacing during processing; after the sheet metal is placed in place, it is pre-positioned through the positioning hole 5 to ensure that the approximate position of the sheet metal meets the processing requirements; then the electric push rod 13 is started; its output force is transmitted to the serrated bar 11 through the connecting bar 12; as the electric push rod is extended and lowered, the serrated bar 11 also drops and meshes with the gear 9 below; this meshing transmission method has the characteristics of high transmission efficiency and stable transmission ratio, which can ensure that the rotation speed and direction of the gear 9 are precisely controlled; as the gear 9 rotates, the elliptical block 10 connected to it also starts to rotate; the design of the elliptical block 10 is unique, and its shape matches the arc slot block 14; when the elliptical block 10 rotates to contact the arc slot block 14, a collision force is generated; this collision force causes the arc slot block 14 to drop in the vertical direction, while pulling the spring 7 Stretch; As the arc slot block 14 descends and moves, the slider 17 connected to it also begins to slide in the slide rail 16; the design of the slide rail 16 ensures that the slider 17 can move according to the predetermined trajectory, thereby realizing precise control of the moving trajectory of the arc slot block 14; As the arc slot block 14 moves, the pressure strip 15 also moves synchronously; The design of the pressure strip 15 has a certain elasticity and hardness, and can fit tightly on the surface of the sheet metal; When the pressure strip 15 is pressed on the sheet metal, it will generate a certain pressure to fix the sheet metal on the positioning mold 3; This auxiliary positioning method not only improves the positioning accuracy and stability, but also can adapt to sheet metals of different shapes and sizes, and has strong versatility and flexibility; After completing the auxiliary positioning, the sheet metal can be mainly fixed with a clamp; This combination of positioning and fixing can ensure that the sheet metal always maintains a stable position and posture during the processing, providing a solid foundation for subsequent processing operations.

[0032] Reference Figure 1 and Figure 3The cleaning mechanism 2 includes an industrial vacuum cleaner 208. The bottom of the industrial vacuum cleaner 208 is installed on the left side of the top wall of the base plate 1. The input end of the industrial vacuum cleaner 208 is connected to the negative pressure box 206. The right side of the negative pressure box 206 is connected to the rubber hose 205. The right end of the rubber hose 205 is connected to the hollow tube 204. The rear side of the fixed frame 6 is fixedly connected to the electric push rod 201. One end of the electric push rod 201 passes through the fixed frame 6 and is fixedly connected to the arc rod 203. The end of the arc rod 203 is fixedly connected Connected to the top of the hollow tube 204, the bottom of the hollow tube 204 is evenly connected to multiple air inlet pipes 202, and the output end of the industrial vacuum cleaner 208 is connected to the exhaust pipe 207; a valve 22 is installed on the outer wall of the air inlet pipe 202, and the end of the air inlet pipe 202 is connected to the air collecting plate 21; the front side of the negative pressure box 206 is rotatably connected to the rotating shaft 19, and the outer side of the rotating shaft 19 is fixedly connected to the rotating plate 18; the right side of the interior of the negative pressure box 206 is slidably connected to the filter plate 20, and the top of the filter plate 20 is fixedly connected to the pull ring 23;

[0033] Specifically, the industrial vacuum cleaner 208 is the core. Once its driving input end is started, a strong negative pressure is quickly generated in the negative pressure box 206; the rubber hose 205, with its excellent flexibility and sealing, transmits the negative pressure in the negative pressure box 206 to the hollow tube 204; the hollow tube 204 further transmits the negative pressure to the air collecting plate 21 through the air inlet pipe 202; in this process, the material selection and structural design of the rubber hose 205 and the hollow tube 204 have been strictly considered to ensure the efficient and stable transmission of negative pressure; the air collecting plate 21 is a key component of the entire system, with its sophisticated design and powerful functions; once the negative pressure is transmitted to the air collecting plate 21, it can quickly generate a strong adsorption force to firmly adsorb the waste and dust generated during the processing ; At this time, the electric push rod 201 starts to work, driving the arc rod 203 to move telescopically; the movement of the arc rod 203 is not only flexible and free, but also precisely controllable. It drives the hollow tube 204 to move synchronously, so that the air collecting plate 21 can fit closely to the surface of the positioning mold 3; this fitting design ensures the thoroughness and efficiency of cleaning and adsorption; when the entire cleaning process is completed, the operator only needs to simply turn the turn plate 18 to easily open the negative pressure box 206; then pull out the filter plate 20 through the pull ring 23 to carry out the necessary cleaning work; this design not only facilitates the operator's cleaning work, but also improves the maintainability and service life of the entire equipment. The electric push rod 201 and the electric push rod 1 13 both use Hydraulic Actuators, and the model of the industrial vacuum cleaner 208 is Festool CT SYS.

[0034] Reference Figure 1 and Figure 2 The bottoms of the two beadings 15 are both designed to be non-slip, and the beadings 15 and the positioning mold 3 are designed to be symmetrical;

[0035] Specifically, the anti-slip design increases the stability of the pressure strip 15 when fixing the sheet metal part, and the symmetrical design increases the accuracy of the fixation.

[0036] Working principle: When assisting the positioning of the sheet metal, the sheet metal is placed on the anti-slip groove 4 of the positioning mold 3, the sheet metal is pre-positioned through the positioning hole 5, and the electric push rod 13 is turned on to drive the connecting bar 12 and the serrated bar 11 to extend and descend. The descent of the serrated bar 11 is meshed with the gear 9 to drive the gear 9 and the elliptical block 10 to rotate. The rotation of the elliptical block 10 collides with the arc groove block 14, so that the arc groove block 14 is lowered and the spring 7 is pulled to extend. The movement of the arc groove block 14 drives the slider 17 to slide in the slide rail 16, and the movement trajectory of the arc groove block 14 is planned. The movement of the arc groove block 14 causes the pressure strip 15 to move synchronously, so that the pressure strip 15 is pressed on the sheet metal to assist in positioning and fixing.

[0037] After the sheet metal processing is completed, the industrial vacuum cleaner 208 is turned on to drive the input end to generate negative pressure in the negative pressure box 206. The negative pressure is transmitted to the air collecting plate 21 through the rubber hose 205, the hollow tube 204, and the air inlet pipe 202, and a strong adsorption force is generated through the air collecting plate 21. At the same time, the electric push rod 201 is turned on to drive the arc rod 203 to move telescopically. The movement of the arc rod 203 is synchronized with the movement of the hollow tube 204, so that the air collecting plate 21 fits the surface of the positioning mold 3 to clean and adsorb the positioning mold 3. After the cleaning is completed, the inhaled air is discharged through the exhaust pipe 207. Subsequently, the rotating plate 18 is rotated to open the negative pressure box 206, and the filter plate 20 is pulled out through the pull ring 23 for cleaning.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
