Description

Technical Field

[0001] The present invention belongs to the technical field of computer production, and specifically relates to a computer case drilling and cutting device. Background Art

[0002] The cover plate on the side of a computer case is usually made of acrylic or plastic, with surface openings or a fully transparent design, which can not only display the internal hardware but also assist in heat dissipation through ventilation holes.

[0003] When drilling holes in the cover plate on the side of a computer case, operators generally use laser drilling, drill bits for drilling, or punches for punching. For laser drilling, it requires special lasers and high-precision control system equipment, and the cost is relatively high. At the same time, when the laser beam cuts plastic materials, the high-temperature laser will cause the risk of thermal damage to the materials, resulting in carbonization or molten residues on the plastic edges. When using a drill bit to drill holes in a plastic plate, since it needs to process holes one by one, the processing efficiency is relatively low. For punching with a punch, it can form holes at one time and can quickly complete the processing of multiple holes. However, the bottom edge of the punched hole will bulge outwards, which is likely to scratch people's hands and also affect the aesthetics of the plastic plate. Therefore, to solve the above problems, a computer case drilling and cutting device is proposed. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a computer case drilling and cutting device, which solves the problems that the existing methods will cause damage to the materials, have low processing efficiency, or the punched edges bulge when processing the plastic side plates of a computer.

[0005] To achieve the above object, the present invention provides the following technical solution: A computer case drilling and cutting device includes a bracket and a hydraulic cylinder, conveying rollers, a plate member, and a cross frame arranged thereon, and further includes: a punch mechanism, which is equidistantly arranged at the bottom of the cross frame; support cylinders, which are equidistantly fixedly connected to the bottom of the bracket; inner cylinders, which are connected to the support cylinders by bearings; A tray mechanism and a scraper, both of which are arranged on the top of the inner cylinder, and when the tray mechanism moves downward, it can drive the scraper to tilt up; Wherein two groups of guide grooves are provided on the outer part of the support cylinder; The tray mechanism includes a tray body movably connected to the inner cylinder. Symmetrically fixed shafts are provided on the tray body. A tension member is sleeved on the top of the inner cylinder. The shafts pass through the inner cylinder and the bottom of the tension member and can slide along the guide grooves; The bottom end of the scraper is a cutter head; a convex shaft that can slide on the top end of the scraper is provided on the top of the tension member; After the punch mechanism moves downward to punch the plate member, it can squeeze the pallet body to move downward, so that the shaft body drives the scraper and the cutter head to tilt and contact the edge at the bottom of the hole of the plate member through the tension member and the convex shaft, and the rotation of the inner cylinder and the scraper can also be caused by the sliding of the shaft body along the guide groove to cut the edge at the bottom of the punch hole.

[0006] Preferably, the inner diameter of the inner cylinder is larger than the diameter of the bottom of the punch mechanism.

[0007] Preferably, an arc-shaped member is fixedly connected to the shaft body. The arc-shaped member can rotate circumferentially at the bottom of the tension member and keep the pallet body in an inclined state. When the punch mechanism moves downward to squeeze the pallet body, it can be restored to a horizontal state.

[0008] Preferably, a limiting member that overlaps with the arc-shaped member in the rotation direction is fixedly connected inside the tension member; On one side of the axis of the pallet body, round holes are symmetrically arranged, so that the unbalanced force on the pallet body drives the arc-shaped member to abut against the limiting member and keep it in an inclined state for the discharge of the scrap.

[0009] Preferably, the punch mechanism includes a connecting seat, a spring rod, a grinding member and a punch body; The connecting seat is fixedly installed at the bottom of the cross frame. The punch body is connected to the bottom of the connecting seat by bearings. The spring rod is connected to the inside of the punch body by splines, and the spring rod has a downward trend under its own elastic force; The bottom end of the spring rod is a rubber plate and extends below the punch body. After the punch body passes through the plate member, the bottom of the grinding member can be in contact with the upper edge of the punch hole on the plate member, and the bottom of the spring rod can be in contact with the pallet body through the scrap of the punched plate member and rotate synchronously when the pallet body moves downward.

[0010] Preferably, the grinding member includes an elastic member and a grinding ring. The top end of the elastic member is in contact with the bottom of the connecting seat. The bottom end of the elastic member is used to support the grinding ring so that it has a downward trend. The diameters of the top and bottom of the grinding ring are respectively larger and smaller than the diameter of the bottom of the punch body. The grinding ring can only move along the axial direction under the limit of the punch body.

[0011] Preferably, anti-slip support members are also equidistantly arranged on the pallet mechanism, and the bottom of the spring rod can be in contact with the anti-slip support members through the punching scrap of the plate member.

[0012] Preferably, the anti-slip support member is hinged to the pallet body and is in a folded shape. Both ends of it can extend to the side of the pallet body. The end of the long side of the anti-slip support member is rough, and the end of the short side is smooth; In the initial state, the long side of the anti-slip support member is inside the pallet body. When the short side of the anti-slip support member is subjected to a downward pressure, the whole anti-slip support member can rotate and its long side can be lifted to contact the punching scrap of the plate member.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In the above solution, the hydraulic cylinder is operated to drive the cross frame to push the punch mechanism downward to punch the plate. Subsequently, the bottom of the punch mechanism contacts and presses the platen body downward through the punching waste, so that the shaft body drives the bottom of the tension member to move downward, and the top of the tension member will also move downward under the tension of its bottom and make the scraper rotate around the shaft through the convex shaft, so that the tool head contacts the edge of the bottom of the hole on the plate, and the shaft body will also move along the guide groove. At this time, the shaft body will force the inner cylinder to rotate, so that the scraper and the tool head rotate to cut and chamfer the bottom of the hole, solving the problem of the bulge at the bottom edge when punching the plate; In the above solution, when the punch mechanism moves downward, the spring rod will first contact the plate and fix it. When the punch body passes through the plate, under the elastic force of the elastic member, the grinding ring will contact the upper edge of the punched hole. The spring rod contacts the platen body through the punching waste of the plate. When the punch mechanism pushes the platen body downward, it will also make the spring rod, the punch body and the grinding ring rotate, so that the grinding ring rotates and chamfers the upper edge of the punched hole; In the above solution, when the punch mechanism resets and moves upward to above the plate, the platen body will rotate to an inclined state due to its own gravity imbalance. At this time, the punching waste on the platen body will slide off the platen body and fall through the platen body, facilitating the continuous operation of the device to improve the processing efficiency.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figures 1 to 10 shown, the present invention provides a computer case drilling and cutting device, including a bracket 1 and a hydraulic cylinder 11, a conveyor roller 8, a plate part 7 and a cross frame 12 arranged thereon, and further including: a punch mechanism 2, which is equidistantly arranged at the bottom of the cross frame 12; a support cylinder 3, which is equidistantly fixed at the bottom of the bracket 1; an inner cylinder 4, which is connected to the support cylinder 3 by bearings; a pallet mechanism 5 and a scraper 6, both of which are arranged at the top of the inner cylinder 4, and the downward movement of the pallet mechanism 5 can drive the scraper 6 to tilt; wherein two groups of guide grooves 31 are provided on the outside of the support cylinder 3; the inner diameter of the inner cylinder 4 is larger than the diameter of the bottom of the punch mechanism 2; The pallet mechanism 5 includes a pallet body 51 movably connected to the inner cylinder 4, symmetrically fixed shafts 52 on the pallet body 51, a tension part 53 is sleeved on the top of the inner cylinder 4, and the shafts 52 pass through the inner cylinder 4 and the bottom of the tension part 53 and can slide along the guide grooves 31; The bottom end of the scraper 6 is a tool tip 61; a convex shaft 531 that can slide on the top end of the scraper 6 is arranged at the top of the tension part 53; After the punch mechanism 2 descends to punch the plate part 7, it can squeeze the pallet body 51 to descend, so that the shafts 52 drive the scraper 6 and the tool tip 61 to tilt and contact the edge of the bottom of the hole of the plate part 7 through the tension part 53 and the convex shaft 531, and the sliding of the shafts 52 along the guide grooves 31 can also make the inner cylinder 4 and the scraper 6 rotate to cut the edge of the bottom of the punch hole.

[0018] Adopting the above solution, by operating the hydraulic cylinder 11, the cross frame 12 is pushed to drive the punch mechanism 2 to move downward to punch the plate member 7. Subsequently, the bottom of the punch mechanism 2 contacts and squeezes the pallet body 51 downward through the punching waste, so that the shaft body 52 drives the bottom of the tension member 53 to move downward, and the top of the tension member 53 will also move downward under the tension of its bottom and make the scraper 6 rotate around the shaft through the convex shaft 531, so that the cutting head 61 contacts the edge of the bottom of the hole punched on the plate member 7, and the shaft body 52 will also move along the guide groove 31. At this time, the shaft body 52 will force the inner cylinder 4 to rotate, so that the scraper 6 and the cutting head 61 rotate to cut and chamfer the bottom of the punched hole, solving the problem of the bulging of the bottom edge of the plate member 7 when punching it.

[0019] As Figures 3 - 9 shown, an arc-shaped member 521 is fixedly connected to the shaft body 52. The arc-shaped member 521 can rotate circumferentially at the bottom of the tension member 53 and keep the pallet body 51 in an inclined state. When the punch mechanism 2 moves downward to squeeze the pallet body 51, it can be restored to a horizontal state. A limiting member 532 which has an overlapping part with the arc-shaped member 521 in the rotation direction is fixedly connected inside the tension member 53. On one side of the axis center of the pallet body 51, round holes are symmetrically arranged, so that the unbalanced force on the pallet body 51 drives the arc-shaped member 521 to abut against the limiting member 532 and keep in an inclined state for the discharge of the punched waste. Adopting the above solution, when the punch mechanism 2 resets and moves upward to above the plate member 7, due to the unbalanced self-gravity of the pallet body 51, it will rotate to an inclined state. At this time, the punching waste on the pallet body 51 will slide off the pallet body 51 and fall through the pallet body 51, facilitating the continuous operation of the device to improve the processing efficiency.

[0020] As Figures 1 - 4 and Figure 10 shown, 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 cross frame 12, the punch body 24 is connected to the bottom of the connecting seat 21 by bearings, the spring rod 22 is connected to the inside of the punch body 24 by splines, and the spring rod 22 has a downward trend under its own elastic force. The bottom end of the spring rod 22 is a rubber plate and extends below the punch body 24. After the punch body 24 passes through the plate member 7, the bottom of the grinding member 23 can be kept in contact with the upper edge of the hole punched on the plate member 7, and the bottom of the spring rod 22 can contact the pallet body 51 through the waste of the punched plate member 7 and rotate synchronously when the pallet body 51 moves downward. The grinding member 23 includes an elastic member 231 and a grinding ring 232. The top end of the elastic member 231 contacts the bottom of the connecting seat 21. The bottom end of the elastic member 231 is used to support the grinding ring 232 to give it a downward trend. The diameters of the top and bottom of the grinding ring 232 are respectively larger and smaller than the diameter of the bottom of the punch body 24. The grinding ring 232 is limited by the punch body 24 and can only move in the axial direction. With the above solution, when the punch mechanism 2 moves downward, the spring rod 22 will first contact the plate member 7 and fix it. When the punch body 24 passes through the plate member 7, under the elastic force of the elastic member 231, the grinding ring 232 will contact the upper edge of the punched hole. The spring rod 22 contacts the support plate body 51 through the punching waste of the plate member 7. When the punch mechanism 2 pushes the support plate body 51 downward, it will also cause the spring rod 22, the punch body 24 and the grinding ring 232 to rotate, so that the grinding ring 232 rotates and grinds the chamfer of the upper edge of the punched hole.

[0021] As Figures 3 - 6 and Figure 9 shown, anti-slip support members 511 are also equidistantly arranged on the support plate mechanism 5. The bottom of the spring rod 22 can contact the anti-slip support members 511 through the punching waste of the plate member 7. The anti-slip support member 511 is hinged to the support plate body 51 and is in a folded shape. Both of its ends can extend to the side of the support plate body 51. The end of the long side of the anti-slip support member 511 is rough, and the end of its short side is smooth. In the initial state, the long side of the anti-slip support member 511 is inside the support plate body 51. When the short side of the anti-slip support member 511 is subjected to a downward pressure, it can cause the whole anti-slip support member 511 to rotate and make its long side rotate up to contact the punching waste of the plate member 7. With the above solution, through the setting of the anti-slip support member 511, it can increase the friction between the bottom of the spring rod 22 and the anti-slip support member 511 through the punching waste of the plate member 7. At the same time, when the support plate body 51 is tilted, the long side of the anti-slip support member 511 will retract into the support plate body 51. At this time, the friction between the punching waste of the plate member 7 and the anti-slip support member 511 decreases, so that the punching waste can slide along the support plate body 51 and fall out through the inner cylinder 4.

[0022] The working principle and usage process of the present invention: The plate member 7 is conveyed between the punch mechanism 2 and the inner cylinder 4 by running the conveying roller 8. The running hydraulic cylinder 11 pushes the punch mechanism 2 downward through the cross frame 12 to punch the plate member 7. Subsequently, the bottom of the punch mechanism 2 contacts and presses the platen body 51 downward through the punching waste, so that the shaft body 52 drives the bottom of the tension member 53 to move downward, and the top of the tension member 53 will also move downward under the tension of its bottom and make the scraper 6 rotate around the shaft through the convex shaft 531, so that the cutter head 61 contacts the edge of the bottom of the punching hole on the plate member 7, and the shaft body 52 will also move along the guide groove 31. At this time, the shaft body 52 will force 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 punching hole; When the punch mechanism 2 moves downward, the spring rod 22 will first contact and fix the plate member 7. When the punch body 24 passes through the plate member 7, under the elastic force of the elastic member 231, the grinding ring 232 will contact the upper edge of the punching hole. The spring rod 22 contacts the platen body 51 through the punching waste of the plate member 7. When the punch mechanism 2 pushes the platen body 51 downward, it will also make the spring rod 22, the punch body 24 and the grinding ring 232 rotate, so that the grinding ring 232 rotates and chamfers the upper edge of the punching hole; When the punch mechanism 2 resets and moves upward to above the plate member 7, the platen body 51 will rotate to an inclined state due to its own gravity imbalance. At this time, the punching waste on the platen body 51 will slide off the platen body 51 and fall through the platen body 51; when the punch mechanism 2 moves downward, its bottom end will squeeze the inclined platen body 51 to make it return to the horizontal state.

[0023] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
