Description

Technical Field

[0001] The invention relates to the field of punching devices, and in particular to a punching device for a range hood butterfly plate hanger assembly. Background Art

[0002] The range hood is an electrical appliance that absorbs oil fumes produced during cooking. The design of the butterfly-wing ring suction plate inside the range hood can form a gathering effect similar to an air hood, so that the oil fumes are quickly sucked in as they rise. This is mainly to enhance the suction effect of the range hood and prevent the oil fumes from escaping. The butterfly-wing ring suction plate is fixed to the bottom of the range hood filter by two hooks and two clips. In order to facilitate disassembly and cleaning, the butterfly plate needs to be installed on the top of the range hood through the bracket assembly.

[0003] In the prior art, when punching holes in the bracket plate, due to its thin plate body, the bottom edge of the hole is easily deformed during the process of the drill bit pressing down to punch the hole, resulting in poor flatness of the plate body at the edge of the hole after punching, and a large amount of cooling waste water with debris will be generated during the drilling process, which cannot be discharged directly. Based on this, we propose a punching device for the butterfly plate bracket assembly of the range hood. Summary of the invention

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0026] This embodiment provides a hole punching device for a range hood butterfly plate bracket assembly, such as Figures 1 to 4As shown, it includes a drilling machine base 1, a drilling table 2 and a drill interface 3. A fixed pressure plate 4 is slidably arranged on the top surface of the drilling table 2. A grinding wheel 10 is rotatably sleeved inside the drilling table 2 below the drill interface 3. Adjustment grooves 5 are symmetrically opened inside the drilling table 2 behind the grinding wheel 10. Adjustment screws 6 slidably inserted inside the adjustment grooves 5 are symmetrically fixed on the bottom surface of the fixed pressure plate 4. Each adjustment screw 6 passes through one end below the adjustment groove 5 and is threadedly sleeved with a fixing nut 7. A wastewater recovery tank 15 is fixed on the top surface of the drilling machine base 1 below the grinding wheel 10. When drilling, The bracket plate is placed on the top surface of the drilling table 2, and then the fixed pressure plate 4 is pulled so that the fixed pressure plate 4 is engaged at the upper corner of the rear side of the bracket plate, and then the adjusting screw 6 is pulled to press the bracket plate, and the fixing nut 7 is tightened to fix it. When drilling, the drill bit is assembled inside the drill bit interface 3, and the drill bit interface 3 is opened to start drilling. During the drilling process, the grinding wheel 10 supports the bracket plate. After the drilling is completed, the grinding wheel 10 is rotated to grind the edge of the hole to avoid protrusions affecting subsequent assembly. The wastewater recovery tank 15 can collect the cooling wastewater generated during drilling.

[0027] On the basis of the above scheme, side support plates 9 are fixed on both sides of the drilling table 2. The top surface of the side support plates 9 is flush with the top surface of the drilling table 2, which is used to support the rack plate to ensure the stability of the rack plate when drilling. A T-rotating hole that cooperates with the grinding wheel 10 is opened inside the drilling table 2 to facilitate the rotation of the grinding wheel 10. A filter box 20 is snap-fitted and sleeved inside the wastewater recovery box 15. A filter screen 21 is fixed on the bottom surface of the filter box 20. Handles are fixed on the side walls of the filter box 20 on both sides above the wastewater recovery box 15. After the cooling waste water is collected inside the wastewater recovery box 15, it is necessary to separate the debris from the wastewater. Then, hold the handle, pull the filter box 20, pull out the filter screen 21, and take out the debris filtered inside the filter screen 21. Pour out the debris inside the filter box 20, and the wastewater can be separated from the debris, which is convenient for wastewater recovery.

[0028] Specifically, the fixed pressure plate 4 is set to be placed in a horizontal L shape. After the bracket plate is placed on the drilling table 2, it is convenient to limit and guide it. The bottom surface of the fixed pressure plate 4 away from the adjusting screw 6 is glued with an anti-slip rubber pad 8 to increase the friction during tightening and ensure the firmness of the bracket plate. The width of the fixing nut 7 is greater than the width of the adjusting groove 5. The length of the wastewater recovery tank 15 is greater than the length of the drilling table 2. Both sides of the wastewater recovery tank 15 are flush with the outer side of the side support plate 9. A drain pipe 19 is fixed to the bottom of the wastewater recovery tank 15 on the side of the drilling machine base 1 for drainage.

[0029] In this embodiment, when the grinding wheel 10 needs to be rotated, the driving structure needs to be turned on. The driving structure is specifically a connecting tube 11 fixed to the bottom of the grinding wheel 10. The connecting tube 11 is rotatably connected to the inside of the drilling table 2 through a bearing. A gear 12 is fixed to the outer surface of the connecting tube 11 on the bottom of the drilling table 2. The side of the gear 12 is meshed and connected with a gear 2 13. The gear 2 13 is rotatably connected to the bottom of the drilling table 2 through a bearing. A servo motor 14 is installed on the bottom of the drilling table 2 below the gear 2 13, and the servo motor 14 is installed on the bottom of the drilling table 2 below the gear 2 13. The output end of the machine 14 is fixed to the bottom surface of the gear 2 13. When it is necessary to grind the edge of the hole, the inner ring diameter of the grinding wheel 10 is smaller than the diameter of the hole. When drilling, the protrusion formed at the edge of the hole is located on the top surface of the grinding wheel 10. The servo motor 14 is turned on, and the servo motor 14 drives the gear 2 13 to rotate. When the gear 2 13 rotates, it drives the meshing gear 12 to rotate, thereby driving the connecting tube 11 to rotate. The rotation of the connecting tube 11 drives the grinding wheel 10 to rotate, so as to grind the edge of the hole.

[0030] During the drilling process, when the hole is initially formed, waste water and debris will flow through the hole to the drilling table 2. Therefore, a rotating joint 16 is fixed to the end of the connecting pipe 11 away from the grinding wheel 10, and a water pipe 17 is fixed to the bottom end of the rotating joint 16. A connecting rod 18 is fixed to the side of the water pipe 17. The top surface of the connecting rod 18 is fixed to the top surface of the drilling table 2. A through hole that matches the end of the drill bit is opened inside the grinding wheel 10. The through hole in the grinding wheel 10 is connected to the inside of the water pipe 17 through the connecting pipe 11 and the rotating joint 16. After the hole is formed, the waste water and waste debris pass through the connecting pipe 11, the rotating joint 16 and the water pipe 17 to flow to the inside of the waste water recovery tank 15, further avoiding the splashing of debris and waste water.

[0031] The specific working principle of the punching device of the range hood butterfly plate hanger assembly proposed in the present invention is: before drilling, the hanger plate is placed on the top surface of the drilling table 2, and then the fixed pressure plate 4 is pulled so that the fixed pressure plate 4 is engaged at the upper corner of the rear side of the hanger plate, and then the adjusting screw 6 is pulled to press the hanger plate, and the fixing nut 7 is tightened and fixed. When drilling, the drill bit is assembled inside the drill bit interface 3, and the drill bit interface 3 is opened to drill. During the drilling process, the grinding wheel 10 supports the hanger plate, and the protrusion formed at the edge of the hole is located on the top surface of the grinding wheel 10.

[0032] After drilling is completed, the servo motor 14 is turned on. The operation of the servo motor 14 drives the gear 2 13 to rotate. The rotation of the gear 2 13 drives the meshing gear 12 to rotate, thereby driving the connecting pipe 11 to rotate. The rotation of the connecting pipe 11 drives the grinding wheel 10 to rotate, so as to grind the edge of the hole. During the drilling process, the waste water and waste chips formed pass through the connecting pipe 11, the rotating joint 16 and the water pipe 17 and flow into the waste water recovery tank 15.
