[0001] The application belongs to the technical field of computer production, and particularly relates to a computer shell drilling and cutting device. BACKGROUND

[0002] The cover plate on the side of the computer case is usually made of acrylic or plastic material, and is designed to be fully transparent or have holes on the surface, so as to display the internal hardware and assist in heat dissipation through the air holes.

[0003] When the cover plate on the side of the computer case is punched, the operator usually adopts laser punching, drilling or punching. For laser punching, a special laser and a high-precision control system are required, which has high equipment cost. Meanwhile, when the laser beam cuts the plastic material, the high-temperature laser may cause thermal damage to the material, so that the edges of the plastic are carbonized or molten. For drilling the plastic plate with a drill bit, the processing efficiency is low because the drill bit needs to be processed hole by hole. For punching, the bottom edge of the punched hole is outwardly raised, which may scratch the hands of people and affect the appearance of the plastic plate. Therefore, the computer shell drilling and cutting device is provided to solve the above problems. SUMMARY

[0039] The supporting plate mechanism 5 comprises a supporting plate body 51 which is movably connected in the inner tube 4, and the supporting plate body 51 is symmetrically fixedly connected with a shaft body 52; a tension part 53 is sleeved at the top of the inner tube 4, and the shaft body 52 passes through the bottom of the inner tube 4 and the tension part 53 and can slide along the guide groove 31;

[0040] The bottom end of the scraper 6 is a tool bit 61; the top of the tension part 53 is provided with a convex shaft 531 which can slide at the top end of the scraper 6;

[0041] The punch mechanism 2 can extrude the support plate body 51 downward after punching the plate 7, so that the shaft 52 drives the scraper 6 and the cutter head 61 to be in contact with the edge of the bottom of the hole of the plate 7, and the shaft 52 can also drive the inner cylinder 4 to rotate to cut the edge of the bottom of the hole.

[0042] By the above scheme, the horizontal frame 12 pushes the punch mechanism 2 downward to punch and cut the plate 7 by driving the hydraulic cylinder 11, and then the bottom of the punch mechanism 2 is in contact with the support plate body 51 through the cutting waste and extrudes the support plate body 51 downward, so that the shaft 52 drives the bottom of the tension member 53 to move downward, and the top of the tension member 53 also moves downward under the tension of the bottom and drives the scraper 6 to rotate around the shaft through the convex shaft 531, so that the cutter head 61 is in contact with the edge of the bottom of the hole of the plate 7, and the shaft 52 also moves along the guide groove 31, so that the shaft 52 forces the inner cylinder 4 to rotate, so that the scraper 6 and the cutter head 61 rotate to cut and chamfer the bottom of the hole, solving the problem of the edge of the bottom of the hole of the plate 7 being raised when punching the plate 7.

[0043] As shown in Figures 3-9 , the shaft 52 is fixedly connected with an arc-shaped member 521, which can rotate around the bottom of the tension member 53 in the circumferential direction and keep the support plate body 51 in an inclined state, and the support plate body 51 can be restored to a horizontal state when the punch mechanism 2 is extruded downward;

[0046] By the above scheme, when the punch mechanism 2 is reset and moves upward to above the plate 7, the support plate body 51 will rotate to an inclined state due to the unbalance of its own gravity, and the cutting waste on the support plate body 51 will slide off the support plate body 51 and fall through the support plate body 51, which facilitates the continuous work of the device to improve the processing efficiency.

[0047] As shown in Figures 1-4 and Figure 10 , the punch mechanism 2 includes a connecting seat 21, a spring rod 22, a grinding member 23 and a punch body 24; the connecting seat 21 is fixedly installed at the bottom of the horizontal frame 12, the punch body 24 is bearing-connected at the bottom of the connecting seat 21, the spring rod 22 is spline-connected in the interior of the punch body 24, and the spring rod 22 has a downward tendency under the elastic force of itself;

[0048] The bottom end of the spring rod 22 is a rubber plate and extends below the punch body 24, the punch body 24 can make the bottom of the grinding part 23 keep in contact with the upper edge of the upper punching hole of the plate piece 7 after passing through the plate piece 7, and the bottom of the spring rod 22 can be in contact with the supporting plate body 51 through the waste punched out of the plate piece 7 and rotate synchronously when the supporting plate body 51 goes down;

[0049] The grinding part 23 comprises an elastic part 231 and a grinding ring 232, the top end of the elastic part 231 is in contact with the bottom of the connecting seat 21, the bottom end of the elastic part 231 is used for supporting the grinding ring 232 so that the grinding ring 232 has a downward trend, the diameters of the top and bottom of the grinding ring 232 are greater and smaller than the diameter of the bottom of the punch body 24 respectively, and the grinding ring 232 can only move in the axial direction under the limiting of the punch body 24;

[0050] By adopting the above scheme, the spring rod 22 will first contact and fix the plate piece 7 through the downward movement of the punch mechanism 2, the grinding ring 232 will be in contact with the upper end edge of the punching hole under the elastic force of the elastic part 231 after the punch body 24 passes through the plate piece 7, the spring rod 22 is in contact with the supporting plate body 51 through the punching waste of the plate piece 7, and the spring rod 22, the punch body 24 and the grinding ring 232 will rotate when the supporting plate body 51 goes down under the pushing of the punch mechanism 2, so that the grinding ring 232 rotates and grinds the upper end edge of the punching hole.

[0051] As shown in Figures 3-6 and Figure 9 The supporting plate mechanism 5 is also provided with anti-skid supporting parts 511 at equal intervals, and the bottom of the spring rod 22 can be in contact with the anti-skid supporting parts 511 through the punching waste of the plate piece 7;
