Description

Technical Field

[0001] This invention relates to the field of high-end equipment manufacturing, and in particular to an opening device for high-end equipment manufacturing. Background Technology

[0002] In the process of processing the outer shell of high-end equipment, it is usually necessary to make holes in the outer shell to facilitate subsequent processing.

[0003] A search revealed Chinese patent application CN114260723A, which discloses a drilling device for high-end equipment manufacturing, relating to the field of equipment manufacturing technology. This drilling device includes a base, a column mounted on the base, an adjustable lifting platform mounted on the column, a fixed head at the top of the column, a first motor on one side of the fixed head, and a drill bit connecting shaft on the other side. A hole drill is mounted on the drill bit connecting shaft, and the first motor drives the drill bit connecting shaft to rotate via a transmission component. This invention can automatically adjust the height of the lifting platform, allowing the workpiece to be automatically drilled using the hole drill. It is simple to operate, has high work efficiency, and can reduce labor costs.

[0004] When performing drilling operations on high-end equipment, existing equipment typically fixes the plates used for manufacturing the equipment below a rotating rod and drills through them. However, at the moment the drill rod contacts the plate, the plate's surface is relatively smooth, causing the drill rod to slide on the plate, leaving scratches on its surface and affecting the manufacturing of the high-end equipment. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drilling device for high-end equipment manufacturing includes a worktable, a support mechanism, and a drilling mechanism. The support mechanism is located on the top of the worktable. The drilling mechanism consists of a drilling assembly and a lifting assembly. The lifting assembly is located on the top of the worktable, and the drilling assembly is located on one side of the lifting assembly. The drilling assembly includes a drilling motor, a support plate, a rotating shaft, and a drill rod. The support plate is fixed to one side of the lifting assembly, and its top is fixedly connected to the drilling motor. The rotating shaft is rotatably connected to the support plate through a bearing, and its top is fixedly connected to the drilling motor. The drill rod is fixed to the bottom of the rotating shaft. A positioning mechanism is provided on one side of the worktable. The positioning mechanism includes a positioning rail, a positioning screw, a turntable, a connecting plate, a positioning pressure plate, and a positioning sleeve. The positioning rail is fixed to the worktable, and its upper and lower ends are rotatably connected to the positioning screw via bearings. The turntable is fixed to the positioning screw. A threaded hole adapted to the positioning screw is opened on one side of the top of the connecting plate. The threaded hole is threadedly connected to the positioning screw. The positioning sleeve is fixed to one side of the connecting plate, and its bottom is provided with multiple protruding teeth arranged in a ring. The positioning pressure plate is fixed to the bottom of the connecting plate, and the bottom of the positioning pressure plate is provided with an anti-slip groove. The positioning sleeve is located directly below the drill rod, and its inner diameter is the same as the diameter of the drill rod. The bottom of the drill rod is provided with multiple anti-slip teeth.

[0006] Preferably, the lifting assembly includes a lifting seat, a lifting screw, a lifting motor, a lifting block, and a connecting shaft. The lifting seat is fixed on the workbench and has a lifting port on one side. The upper and lower ends of the lifting port are rotatably connected to the lifting screw via bearings. The lifting motor is fixed to the top of the lifting seat and its output end is fixedly connected to the lifting screw. The lifting block is slidably connected inside the lifting port and has a threaded opening on its top that matches the lifting screw. The threaded opening is threadedly connected to the lifting screw. The two ends of the connecting shaft are fixedly connected to the lifting block and the support plate, respectively.

[0007] Preferably, the support mechanism includes a support base, two side plates, a clamping plate, a limiting bolt, a limiting plate, two limiting rods, and two fastening bolts. The two side plates are fixed to the workbench, and the support base is fixed between the two side plates. The top of the support base has a through hole, the position of which corresponds to the position of the drill rod and the position of the positioning sleeve. One side plate has pull holes at both ends on one side, and the two limiting rods are slidably connected in the two pull holes. The two limiting rods are fixedly connected to the limiting plate. The top of the two pull holes has a threaded through hole adapted to the fastening bolt, and the threaded through hole is threadedly connected to the fastening bolt. The other side plate has a threaded through port adapted to the limiting bolt on one side, and the threaded through port is threadedly connected to the limiting bolt. A clamping spring is fixed between the clamping plate and the other side plate, and one end of the limiting bolt contacts the clamping plate.

[0008] Preferably, multiple anti-slip ridges are provided on one side of the limiting plate and one side of the clamping plate.

[0009] Preferably, a slot is provided on one side of the lifting seat near the bottom, a cooling chamber is provided inside the positioning sleeve, and a cooling mechanism is provided between the cooling chamber and the slot to cool the drill rod.

[0010] Preferably, the cooling mechanism includes an upper top plate, a lower top plate, an extrusion plate, a compression pad, and two connecting pipes. The upper top plate is fixed to the bottom of the lifting screw. The upper and lower top plates each have multiple annularly distributed protrusions on opposite sides. The upper and lower protrusions cooperate to rotate the upper top plate while driving the lower top plate to move up and down reciprocally. The extrusion plate is slidably connected to the slot, and its top is fixedly connected to the lower top plate. The compression pad is disposed between the bottom of the extrusion plate and the slot, and its interior is hollow and filled with coolant. A pressure plate spring is fixed between the extrusion plate and the slot. The cooling chamber and the compression pad are connected by two connecting pipes, which are arranged vertically.

[0011] Preferably, both connecting pipes are equipped with one-way valves to allow the coolant inside the compression pad to be transported to the cooling chamber through the upper connecting pipe, while allowing the coolant in the cooling chamber to be discharged into the compression pad through the lower connecting pipe.

[0012] The beneficial effects of this invention are as follows: 1. This invention, through the provision of a support mechanism, a hole-opening mechanism, and a positioning mechanism, fixes the plate to the support mechanism during hole-opening. After fixing, the turntable is rotated, causing the turntable to drive the positioning screw to rotate. Simultaneously, the positioning screw drives the connecting plate downward, thereby pressing and fixing the protruding teeth and the positioning pressure plate onto the upper surface of the plate. At this time, the lifting assembly is activated, which drives the hole-opening assembly to move downward. Simultaneously, the hole-opening assembly operates. When the drill rod contacts the upper surface of the plate, the drill rod will open the plate. At this time, the drill rod is located inside the positioning sleeve. Since the inner diameter of the positioning sleeve is the same as the diameter of the drill rod, it can prevent the drill rod from sliding at the moment of contact with the plate, thus avoiding scratches on the surface of the plate. The debris generated during hole opening is discharged through the gap between two adjacent protruding teeth. Therefore, the debris does not affect the positioning of the positioning sleeve. During this process, the protruding teeth and anti-slip groove can prevent the plate from shifting due to vibration generated during drilling, thus avoiding affecting the hole opening of the plate. 2. This invention utilizes a cooling mechanism where, as the drill rod moves downward via the lifting assembly, the upper top plate rotates synchronously with the lifting screw. The cooperation between the upper and lower top plates causes the upper top plate to reciprocate up and down while rotating, and simultaneously, the lower top plate reciprocates the pressing plate. This pressing plate compresses the compression pad, causing the coolant inside the compression pad to be compressed and transported to the cooling chamber through two connecting pipes, one above the other. The coolant enters the cooling chamber through the upper connecting pipe and exits through the lower connecting pipe, thus achieving circulation of the coolant within the cooling chamber. This improves the cooling effect of the drill rod and prevents damage caused by heat generated during drilling, which could reduce the drill rod's strength. Attached Figure Description

[0015] Example 1, referring to Figures 1-5 A drilling device for high-end equipment manufacturing includes a worktable 1, a support mechanism 2, and a drilling mechanism. The support mechanism 2 is located on the top of the worktable 1 to support and fix the plate. The drilling mechanism consists of a drilling component 3 and a lifting component 4. The lifting component 4 is located on the top of the worktable 1, and the drilling component 3 is located on one side of the lifting component 4. The drilling component 3 can move up and down reciprocally through the lifting component 4. The drilling component 3 includes a drilling motor 16, a support plate 15, a rotating shaft 17, and a drill rod 18. The support plate 15 is fixed to one side of the lifting mechanism 4, and its top is bolted to the drilling motor 16. The rotating shaft 17 is rotatably connected to the support plate 15 through a bearing, and its top is fixedly connected to the drilling motor 16. The drill rod 18 is welded to the bottom of the rotating shaft 17. A positioning mechanism 5 is provided on one side of the worktable 1. The positioning mechanism 5 includes a positioning... The system comprises a positioning rail 27, a positioning screw 28, a turntable 29, a connecting plate 30, a positioning pressure plate 33, and a positioning sleeve 31. The positioning rail 27 is fixed to the worktable 1 by bolts, and its upper and lower ends are rotatably connected to the positioning screw 28 through bearings. The turntable 29 is fixed to the positioning screw 28 by bolts. A threaded hole adapted to the positioning screw 28 is opened on one side of the top of the connecting plate 30, and the threaded hole is threadedly connected to the positioning screw 28. The positioning sleeve 31 is welded to one side of the connecting plate 30, and its bottom is provided with multiple annularly distributed protrusions 32. The positioning pressure plate 33 is fixed to the bottom of the connecting plate 30 by bolts, and the bottom of the positioning pressure plate 33 is provided with an anti-slip groove 34. The positioning sleeve 31 is located directly below the drill rod 18, and its inner diameter is the same as the diameter of the drill rod 18. The bottom of the drill rod 18 is provided with multiple anti-slip teeth 19.

[0016] When drilling holes in the sheet metal, the sheet metal is fixed to the support mechanism 2. After fixing, the turntable 29 is rotated, causing the positioning screw 28 to rotate. Simultaneously, the positioning screw 28 moves the connecting plate 30 downwards, causing the protruding teeth 32 and the positioning pressure plate 33 to press and fix onto the upper surface of the sheet metal. At this time, the lifting assembly 4 is activated, causing the drilling assembly 3 to move downwards. Simultaneously, the drilling assembly 3 begins operation. When the drill rod 18 contacts the upper surface of the sheet metal, the drill rod 18 will... When the part is drilled, the drill rod 18 is located inside the positioning sleeve 31. Since the inner diameter of the positioning sleeve 31 is the same as the diameter of the drill rod 18, it can prevent the drill rod 18 from sliding at the moment of contact with the part, thus avoiding scratches on the surface of the part. The debris generated during drilling will be discharged through the gap between two adjacent teeth 32. Therefore, the debris will not affect the positioning of the positioning sleeve 31. During this process, the teeth 32 and the anti-slip groove 34 can prevent the part from shifting due to vibration generated during drilling.

[0017] In this invention, the lifting assembly 4 includes a lifting seat 20, a lifting screw 23, a lifting motor 24, a lifting block 25, and a connecting shaft 26. The lifting seat 20 is fixed to the workbench 1 by bolts, and a lifting port 21 is provided on one side. The upper and lower ends of the lifting port 21 are rotatably connected to the lifting screw 23 through bearings. The lifting motor 24 is fixed to the top of the lifting seat 20 by bolts, and one of its output ends is fixedly connected to the lifting screw 23. The lifting block 25 is slidably connected in the lifting port 21, and a threaded opening adapted to the lifting screw 23 is provided on its top. The threaded opening is threadedly connected to the lifting screw 23. The two ends of the connecting shaft 26 are respectively bolted to the lifting block 25 and the support plate 15. When the lifting assembly 4 is working, the lifting motor 24 is started, and the lifting motor 24 drives the lifting screw 23 to rotate. While the lifting screw 23 is rotating, it drives the lifting block 25 to move up and down, thereby realizing the up and down movement of the hole-opening assembly 3, which facilitates hole opening on the plate.

[0018] In this invention, the support mechanism 2 includes a support base 6, two side plates 7, a clamping plate 9, a limiting bolt 8, a limiting plate 13, two limiting rods 11, and two fastening bolts 14. The two side plates 7 are fixed to the workbench 1 by bolts. The support base 6 is welded between the two side plates 7. The top of the support base 6 has a through hole 12, the position of which corresponds to the position of the drill rod 18 and the position of the positioning sleeve 31. Both ends of one side plate 7 have pull holes, and the two limiting rods 11 are slidably connected in the two pull holes. The two limiting rods 11 are connected to the limiting plate 13 by bolts. The top of each of the two pull holes has a threaded through hole adapted to the fastening bolt 14, and the threaded through hole is threadedly connected to the fastening bolt 14. One side of the other side plate 7 has a threaded through hole adapted to the limiting bolt 8. A matching threaded port is provided, which is compatible with the limit bolt 8. A clamping spring 10 is welded between the clamping plate 9 and the other side plate 7. One end of the limit bolt 8 contacts the clamping plate 9. When drilling a hole in the plate, the plate is placed on the support seat 6. The support seat 6 supports the plate to prevent it from bending due to the pressure of the drill rod during drilling. After placement, the fastening bolt 14 is tightened according to the position of the hole, so that the limit rod 11 slides inside the pull hole, thereby adjusting the position of the limit plate 13. The limit plate 13 aligns the position of the hole in the plate with the opening part 12. After setting, the fastening bolt 14 is tightened, and the limit bolt 8 is rotated at the same time. The limit bolt 8 drives the clamping plate 9 to move, thereby clamping and fixing the plate.

[0019] Based on the above, in order to improve the stability of the plate when making holes, multiple anti-slip ridges are provided on one side of the limiting plate 13 and the clamping plate 9 to increase the friction between the limiting plate 13 and the clamping plate 9 and the plate, so as to prevent the plate from shaking when making holes.

[0020] Example 2, refer to Figures 1-7 A high-end equipment manufacturing opening device, compared with embodiment 1, has a slot 22 opened on one side of the lifting seat 20 near the bottom, a cooling cavity 35 opened inside the positioning sleeve 31, and a cooling mechanism 36 is provided between the cooling cavity 35 and the slot 22 to cool the drill rod 18.

[0021] Based on the above, the cooling mechanism 36 includes an upper top plate 41, a lower top plate 42, a pressing plate 37, a compression pad 38, and two connecting pipes 40. The upper top plate 41 is fixed to the bottom of the lifting screw 23 by bolts. Multiple annularly distributed protrusions are provided on opposite sides of the upper top plate 41 and the lower top plate 42. The upper and lower protrusions are fitted together to allow the upper top plate 41 to rotate while simultaneously driving the lower top plate 42 to move up and down reciprocally. The pressing plate 37 is slidably connected within the slot 22, and its top is bolted to the lower top plate 42. The compression pad 38... 8 is located between the bottom of the extrusion plate 37 and the slot 22. Its interior is hollow and filled with coolant. A pressure plate spring 39 is welded between the extrusion plate 37 and the slot 22. The cooling chamber 35 and the compression pad 38 are connected by two connecting pipes 40, which are arranged vertically. Both connecting pipes 40 are equipped with one-way valves to allow the coolant inside the compression pad 38 to be transported to the cooling chamber 35 through the upper connecting pipe 40, while allowing the coolant in the cooling chamber 35 to be discharged to the compression pad 38 through the lower connecting pipe 40.

[0022] When the drill rod 18 moves downward via the lifting assembly 4, the upper top plate 41 rotates synchronously with the rotation of the lifting screw 23. At this time, the cooperation between the upper top plate 41 and the lower top plate 42 causes the upper top plate 41 to rotate while driving the lower top plate 42 to move up and down reciprocally. As the lower top plate 42 moves up and down, it also drives the extrusion plate 37 to move up and down reciprocally. When the extrusion plate 37 moves up and down reciprocally, it extrudes the compression pad 38. At this time, the coolant inside the compression pad 38 is compressed and then transported to the interior of the cooling chamber 35 through the connecting pipe 40. There are two connecting pipes 40, which are distributed vertically. The coolant inside the cooling chamber 35 enters through the upper connecting pipe 40 and is discharged through the lower connecting pipe 40. The two connecting pipes 40 realize the circulation of coolant inside the cooling chamber 35, thereby improving the cooling effect of the drill rod 18 and preventing the drill rod 18 from being damaged due to the heat generated during drilling.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
