Description

Technical Field

[0001] This invention relates to the field of corner code processing equipment, specifically a deburring device for corner code mounting holes. Background Technology

[0002] Corner brackets are a type of connector widely used in the furniture and home decoration industry. They are now mostly made of aluminum. Because they need to be used with various screws, nails and other fasteners, these corner brackets have various through holes. These through holes are usually punched or drilled. However, whether punched or drilled, there will be various burrs on the machined surface. If these burrs are not removed, they can easily cut the hands during subsequent use. Some of the smaller burrs can even penetrate into the skin and are not easy to remove, which is very harmful to the user. Moreover, since it is not clear from which side of the corner bracket the punching or drilling started (if the machining is from the inside out, the burrs will appear on the outside surface, and vice versa), burrs may exist on both the inner and outer surfaces of the corner bracket.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 9This invention provides a technical solution: a deburring device for corner code mounting holes, including a device base 1, a slanted frame base 2 on the top working surface of the device base 1, a hollow inner side cleaning device 3 fixed above the slanted frame base 1, the inner side cleaning device 3 being used to clean the inner side of the corner code 8 and discharge the cleaned metal powder, a rubber wheel power device 4 being provided directly above the inner side cleaning device 3, the rubber wheel power device 4 being used to drive the corner code 8 to move, and outer side cleaning devices 5 being provided on both sides of the rubber wheel power device 4, the top of the outer side cleaning device 5 being connected to the output shaft of a lifting cylinder 6, the outer side cleaning device 5 being used to clean the outer side of the corner code 8.

[0031] In this embodiment, the inclined frame base 2 includes support ribs 21 on both ends and an inclined frame 22. The inclined frame 22 is a slope with an inclined bottom surface. It is connected to the right-angle sliding seat 31 through the support ribs 21. The inclined frame 22 with an inclined bottom surface can continuously slide the collected metal dust downwards.

[0032] In this embodiment, the inner surface cleaning device 3 includes a right-angle sliding seat 31, which is a hollow structure. Dust collection grooves 32 are respectively provided on the two right-angled surfaces of the right-angle sliding seat 31. Several elastic pillars 33 are provided within the dust collection grooves 32. Dust collection holes 34 are provided on the upper and lower sides of the dust collection grooves 32. The right-angle sliding seat 31 is fixed to the top of the inclined frame base 2, and a dust collection cover 35 is provided at its connection with the lower side of the inclined frame base 2. A dust passage 36 is located directly below the dust collection cover 35 on the device base 1. A suction cover 37 is fixed to the device base 1 directly below the dust passage 36. Sandpaper 38 is wound around the elastic pillars 33. The right angle of the right-angle sliding seat 31 faces... The corner bracket is placed on top, with rounded corners at right angles to avoid interference with the right angle of the corner bracket 8 and to reduce friction when the corner bracket 8 is placed on the right angle sliding seat 31. The elastic column 33 can be made of urethane. The height of the elastic column 33 is higher than the surface of the right angle sliding seat 31. After wrapping sandpaper 37 on its surface, when the corner bracket 8 passes through these elastic columns 33, it will bend them and generate an upward elastic force. Under this elastic force, the sandpaper 37 will polish off the burrs on the corner bracket 8. Then, these burrs are collected by the suction of the suction hood 36 (which is connected to an external air pump, not shown in the figure) through the dust collection hole 34, the inclined frame 22, the dust collection hood 34, and the dust passage 35.

[0033] In this embodiment, the rubber wheel power unit 4 includes multiple rubber wheels 41, a rotating shaft 42, a power wheel 43, multiple driven wheels 44, and a power motor 45. The rubber wheels 41 are located directly above the right-angle sliding seat 31. Each rubber wheel 41 has a contoured groove 46 and is mounted on the rotating shaft 42. The power wheel 43 is connected to the outermost rubber wheel 41 via one of the rotating shafts. The diameter of the power wheel 43 is smaller than that of the driven wheels 44. The power wheel 43 is connected to all the driven wheels 44 via a belt 47. The driven wheels 44 are mounted on the rotating shaft 42. The power motor 45 is mounted on the outermost rubber wheel 41. The side cleaning device 5 has its output shaft connected to the power wheel 43. The power wheel 43 is driven to rotate by the power motor 45. The power wheel 43 drives the driven wheel 44 to rotate via the belt 47. Since the power wheel 43 and the driven wheel 44 are both mounted on the rotating shaft 42, and the rubber wheel 41 is also mounted on the rotating shaft 42, the rubber wheel 41 will also rotate. The two ends of these rotating shafts 42 (except for one connected to the power wheel 43) are rotatably connected to the connecting top block 52. The lifting cylinder 6 drives the rubber wheel 41 to press down. The pressing down of the rubber wheel 41 generates friction. When the rubber wheel 41 rotates, it will continuously move the corner bracket 8 backward.

[0034] In this embodiment, the outer surface cleaning device 5 includes two symmetrically arranged sets, including inclined cleaning blocks 51, connecting top blocks 52, inclined grooves 53, elastic pillars 54, and air holes 55. The inclined cleaning blocks 51 are respectively located above the two right-angled surfaces of the right-angle sliding seat 31. The connecting top blocks 52 are fixed to the top of the inclined cleaning blocks 51. The inclined grooves 53 are located on the inclined surface of the inclined cleaning blocks 51. The elastic pillars 54 are fixed in the inclined grooves 53, and sandpaper 56 is wound around the elastic pillars 54. The air holes 55 are located at the upper and lower ends of the inclined grooves 53. An air blowing channel 57 is provided behind 55. The end of the air blowing channel 57 is provided with a cover 58. Multiple air blowing pipes 59 are provided on the cover 58. The second elastic column 54 is made of the same material as the first elastic column 33. When the inclined cleaning block 51 is driven down by the lifting cylinder 6, these second elastic columns 54 also bend. The outer surface of the diagonal code 8 is polished by the second sandpaper 56 in the same principle as the first elastic column 33. Then, air is blown through the air blowing pipe 59. The blown air will blow up the polished metal burrs after passing through the air blowing hole 55. They are then sucked in by the suction force generated by the dust collection hole 34 to complete the collection of metal dust.

[0035] In this embodiment, the lifting cylinder 6 comprises multiple cylinders, and the lifting cylinder 6 is mounted on the device base 1 via a cylinder bracket 7.

[0036] Working principle: First, connect the suction device to the bottom of the suction hood 37, then connect the air blowing device to the air blowing pipe 59, then turn on the power motor 45 to make the rubber wheel 41 start to rotate. Then, place the corner brackets 8 one by one with their openings facing down on the right-angle sliding seat 31. Control the lifting cylinder 7 to press the inclined cleaning block 51 downward. At the same time, since the entire rubber wheel power device 4 is installed on the inclined cleaning block 41 and the connecting top block 52, the placed corner brackets 8 will be driven backward by the rubber wheel 41 that is also pressed down. Then, the corner brackets 8 that are moving backward will bend the higher elastic column 1 33 and elastic column 2 54 during the movement. In this way, the elastic column 1 33 The elastic force generated on the elastic column 54 will act on the inner and outer surfaces of the corner bracket 8. The wrapped sandpaper 38 and sandpaper 56 will grind off the metal burrs on the corner bracket 8. Then, the metal burrs ground off on the right-angle sliding seat 31 will be directly sucked into the inclined frame 22 by the suction force generated by the suction hood 37 through the dust collection hole 34, and finally discharged through the suction hood 37. The metal burrs ground off on the inclined surface cleaning block 51 will be blown out through the air hole 55 by the gas blown in from the air pipe 59, so that these metal burrs will not stay in the inclined surface groove. Then, these metal burrs will also be sucked into the dust collection hole 3, achieving the purpose of centralized collection of metal burrs.

[0037] Based on the above, the inner surface cleaning device of this invention can effectively remove metal burrs that punch or drill out on the inner surface of the corner bracket, which not only improves the quality of the corner bracket but also prevents these metal burrs from injuring people; the outer surface cleaning device of this invention can effectively remove metal burrs that punch or drill out on the outer surface of the corner bracket, which not only improves the quality of the corner bracket but also prevents these metal burrs from injuring people; this invention can also collect the cleaned metal powder in a concentrated manner to prevent metal dust from scattering and causing damage to the human body.

[0038] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
