Description

Technical Field

[0002] A router is a computer network device that can transmit data to the destination by packaging the data in networks. This process is called routing. A router is a device that connects two or more separate networks. Currently, routers have been widely used in all walks of life. Products of various grades have become the main force for realizing internal connections within various backbone networks, interconnection between backbone networks, and interconnection between backbone networks and the Internet.

[0003] The shell of a router is usually made of plastic. Plastic shells are more common and provide better insulation performance and lighter weight. They are divided into an upper shell and a bottom shell, and the upper shell and the bottom shell are fixed by bolts. Before installation, the two shells need to be punched. The existing Chinese public patent document: CN111645140A discloses a precision punching device for a router plastic shell. The controller is used to control the product position and the operation of the drilling mechanism and the grinding mechanism, so as to achieve accurate drilling of the router shell. The drilling of the device improves the drilling speed and accuracy. However, when the drill bit drills the shell, certain burrs and residues will remain on the top of the shell hole.

[0032] The user can place the shell to be punched on the top of multiple support plates 10, adjust the position of the electric drill 4 through the driving frame 2 and the lifting frame 3, and make the electric drill 4 drill holes in the shell. After the drilling is completed, the movable seat 11 is driven to move by the electric screw 7, so that the movable seat 11 drives the storage box 8 to move to the bottom of the grinding disc 5, so that the grinding disc 5 grinds the burrs on the top of the hole of the shell, and when the grinding disc 5 is close to the hole of the shell, the grinding disc 5 drives the insertion rod 18 at the bottom of the mounting column 17 to insert into the inner wall of the hole, and the insertion rod 18 is attached to the inner wall of the hole.

The outer diameter of the positioning rod 22 is smaller than the inner diameter of the bottom of the nozzle 20. A positioning ring 24 is fixedly installed on the inner side of the rotating drum 12. A spring 25 is fixedly installed between the bottom of the positioning ring 24 and the top of the mounting column 17 to facilitate the resetting of the mounting column 17.

[0035] The slag storage mechanism includes a plurality of baffles 27 equidistantly arranged on the inner side of the storage box 8, and the adjacent baffles 27 are in contact with each other. Rotating rods 28 are fixedly installed at both ends of the baffles 27. The rotating rods 28 are rotatably installed with the inner side of the storage box 8. The plurality of rotating rods 28 located on the left side of the baffles 27 are rotatably installed with a synchronous belt 29. When any rotating rod 28 rotates, the synchronous belt 29 can drive the remaining rotating rods 28 to rotate synchronously. A cavity for installing the synchronous belt 29 is provided inside the storage box 8, and a driven rod 30 is provided on the side of the storage box 8 away from the synchronous belt 29. The driven rod 30 is fixedly connected to one end of the adjacent rotating rod 28, and a gear 31 located on the outside of the storage box 8 is fixedly installed on the outside of the driven rod 30. A positioning column 32 is fixedly installed on the top of the equipment base 1, and a rack plate 33 matched with the gear 31 is fixedly installed on the outside of the positioning column 32. The number of teeth of the gear 31 is twice the number of teeth on the rack plate 33, so that when the gear 31 contacts the rack plate 33, it can drive the gear 31 to rotate half a circle to realize the flipping of the baffle 27. A clamping rod assembly for positioning and preventing the driven rod 30 from rotating is also provided on the outside of the storage box 8;

[0036] The dust entering the storage box 8 can fall on the plane formed by the multiple baffles 27. When the storage box 8 moves, it can drive the gear 31 on the driven rod 30 to contact the rack plate 33 on the positioning column 32, so that the rack plate 33 drives the gear 31 to rotate half a circle, and the gear 31 can drive the corresponding rotating rod 28 to rotate half a circle through the driven rod 30. While the rotating rod 28 drives the corresponding baffle 27 to rotate, it drives the remaining rotating rods 28 to rotate synchronously through the synchronous belt 29.

[0037] Working principle: First, the user places the shell to be punched on the top of multiple support plates 10, and starts the driving frame 2 and the lifting frame 3 on the left side of the equipment base 1, adjusts the electric drill 4 to rotate the punching position of the shell, and punches the shell. The residues produced by the punching pass through the gaps between the adjacent support plates 10 and enter the storage box 8 and fall on the baffle 27. Then, the user starts the electric screw 7, and the electric screw 7 moves through the moving seat 11 to drive the storage box 8 to move along the top of the installation frame 6, and the storage box 8 drives the gear 31 on the driven rod 30 and the positioning column 32 The rack plate 33 on the upper part contacts with the rack plate 33, so that the gear 31 rotates half a circle during the movement. The gear 31 drives the corresponding rotating rod 28 to rotate synchronously through the driven rod 30, and the rotating rod 28 drives the corresponding baffle 27 to rotate, and drives the remaining rotating rods 28 to rotate synchronously through the synchronous belt 29, so as to realize the synchronous flipping of multiple baffles 27, and send the residue to the bottom of the storage box 8. Then, the storage box 8 drives the placement frame 9 to move to the bottom of the grinding disc 5. The user starts the driving frame 2 and the lifting frame 3 on the right side of the equipment base 1, and the installation shell 14 will align the grinding disc 5 with the hole of the shell. The user then starts the motor 15, and the motor 15 drives the drum 12 to rotate through the synchronous belt 16, so that the drum 12 drives the grinding disc 5 to rotate, and the grinding disc 5 contacts the top of the hole to grind the burrs on the top of the hole. At the same time, the collar 26 at the bottom of the mounting post 17 contacts the top of the shell, so that the mounting post 17 moves upward along the inner side of the drum 12, and the mounting post 17 drives the positioning rod 22 to move synchronously through the fixing rod 23, so that the positioning rod 22 The sealing plug 21 is driven away from the bottom inner wall of the nozzle 20, and the bottom of the nozzle 20 is opened. The air pump 19 discharges air from the opening at the bottom of the nozzle 20, so that the air is discharged from the exhaust hole at the bottom of the mounting column 17. In addition, the grinding disc 5 drives the insertion rod 18 to make a circular motion along the inner wall of the hole through the mounting column 17 to grind the inner side of the hole. The airflow discharged from the mounting column 17 can blow the residue generated by grinding into the storage box 8 and fall on the baffle 27 for temporary storage, thereby achieving the effect of comprehensive grinding and cleaning of residues, and improving the production quality of the router shell.

[0038] Example 2: Please refer to Figure 5-Figure 7 The present embodiment further explains the first embodiment. A drawer 34 is slidably installed on the inner side of the storage box 8 in the figure. An opening is provided on the outer side of the storage box 8 for the drawer 34 to slide in a limited position, which is convenient for recycling and cleaning of residues. The bottom of the insertion rod 18 is an arc-shaped structure, and a plurality of scraping grooves equidistantly distributed are provided on the outer side of the insertion rod 18, which is convenient for removing burrs on the inner side of the shell hole. The bottom end of the mounting column 17 is an arc-shaped structure, which is convenient for contacting the hole of the shell. The top opening of the mounting column 17 is a conical structure. The sealing plug 21 is made of rubber to improve the sealing performance of the nozzle 20.

[0039] In the present embodiment, the residues in the storage box 8 can enter the drawer 34 for storage. When the user cleans it later, he can take out the residues by pulling the drawer 34, which is convenient for cleaning. When the insertion rod 18 rotates along the hole of the shell, the burrs in the hole can be quickly removed through the scraping groove on the outside of the insertion rod 18, and the sealing plug 21 is away from the bottom inner wall of the nozzle 20, so that the gas in the air pump 19 can quickly enter the inner side of the mounting column 17 along the conical surface at the top of the mounting column 17, which is convenient for rapid exhaust.

[0040] Example 3: Please refer to Figure 7 and Figure 8 , this embodiment further explains other embodiments. The card rod assembly shown in the figure includes two L-shaped rods 35 symmetrically arranged on the outside of the driven rod 30, one end of the L-shaped rod 35 is fixedly installed on the outside of the storage box 8, and a stop block 36 is slidably installed on the end of the L-shaped rod 35 away from the storage box 8, and a spring 2 37 is fixedly installed between the stop block 36 and the inner side of the L-shaped rod 35, and the end of the stop block 36 away from the spring 2 37 is a hemispherical structure. A spherical groove for limiting and inserting the stop block 36 is opened on the outside of the driven rod 30, which can provide positioning for the driven rod 30 after the driven rod 30 rotates half a circle. Positioning plates 38 are fixedly installed on both ends of the baffle 27, and the side of the positioning plate 38 away from the baffle 27 contacts with the inner side of the storage box 8, provides support for both ends of the baffle 27, and facilitates the synchronous rotation of multiple baffles 27.

[0041] In this embodiment: when the driven rod 30 drives the rotating rod 28 to rotate, the rotating rod 28 drives the baffle 27 to rotate, so that the positioning plates 38 at both ends of the baffle 27 rotate synchronously along the adjacent positioning plates 38, which can provide auxiliary support and positioning for the adjacent positioning plates 38, improve the stability of the rotation of the baffle 27, and the spherical groove of the driven rod 30 pushes the spherical end of the stop block 36 to move, so that the stop block 36 moves along the inner side of the L-shaped rod 35, compressing the spring 2 37, so that after the driven rod 30 rotates half a circle, the spherical groove of the driven rod 30 is aligned with the spherical end of the stop block 36 again, and the rebound force of the spring 2 37 is used to make the stop block 36 inserted into the spherical groove of the driven rod 30, providing positioning for the driven rod 30, preventing the baffle 27 from rotating, and ensuring that the baffle 27 is in a horizontal state, which is convenient for catching the residue dropped during drilling and grinding.
