Description

Technical Field

[0001] The utility model relates to the technical field of aerospace composite materials, in particular to a drilling device with a flexibly replaceable drill bit. Background Art

[0002] Aerospace composite materials are a high-performance new material system used in aerospace vehicles, which is made of two or more heterogeneous, shaped and heterogeneous materials through a special molding process. The purpose of the composite is to improve the performance of the material or make the material meet certain special physical properties (such as light, electricity, heat, sound, magnetism, etc.).

[0003] After searching, it was found that Chinese patent announcement No. CN216266342U discloses a space science aerospace composite material punching device, which greatly improves the stability of the material on the fixed plate and reduces the vibration of the device through the shock-absorbing mechanism. However, the drilling rig of the device is an integrated structure. After long-term work, the drill bit will cause certain wear. The drill bit replacement process of the device is relatively cumbersome and requires a complete replacement, which causes certain losses. At the same time, the device only relies on the autonomous falling of the debris itself when debris is generated, so that the debris cleaning effect is not good. When the drill bit is drilling, some debris will splash and it is difficult to fall into a fixed position. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a drilling device with flexible drill bit replacement, which has the effect of increasing the chip recovery and processing during drilling, is convenient for moving aerospace composite materials so that they can drill holes in different positions, and increases the stability of aerospace composite materials during the drilling process. At the same time, it is suitable for processing aerospace composite materials of different sizes, is convenient for replacing drill bits, and protects the replaced screws, etc., thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drilling device for flexibly replacing a drill bit, comprising a base, an upper surface of the base is provided with a leakage groove, and a switch door is installed on the side by a hinge, a support frame is fixedly installed on one side of the upper surface of the base, a telescopic rod is fixedly installed through the top of the support frame, a frame is fixedly installed on the top of the telescopic rod, a drilling rig is fixedly installed inside the frame, a drill rod is fixedly installed on the bottom end of the drilling rig, a side plate is fixedly installed on the other side of the upper surface of the base, a driving motor is fixedly installed through the outer side of the side plate, and a guide rod is fixedly installed inside the side plate, a threaded rod is fixedly installed at the axis of the driving motor, a movable plate is threadedly installed on the outer circumferential surface of the threaded rod, a vacuum cleaner is fixedly installed on the outer side of the base, a duct is fixedly installed on the input end of the vacuum cleaner, and a dust hood is fixedly installed on the top of the duct.

[0008] Preferably, a group of conduits are fixedly installed at the input end of the vacuum cleaner, and the output end passes through the side of the base and is fixedly connected to the inside of the drain groove.

[0009] Through the above technical solution, when the drill bit drills aerospace composite materials, a large amount of debris will be generated. Part of the debris will automatically fall into the drain groove due to its own weight, and then the debris inside the drain groove will be cleaned and recovered by opening the switch door. Another part of the debris will cause splashing due to the impact force brought by the drill bit. The vacuum cleaner is started to generate suction through the duct and the dust hood. At this time, the splashed debris is absorbed by the suction, and finally enters the vacuum cleaner through the dust hood and the duct, and then discharged into the drain groove through the output end of the vacuum cleaner. This structure increases the effect of debris recovery and processing during drilling.

[0010] Preferably, a group of threaded rods are fixedly installed at the axis of the driving motor, and the other ends of the threaded rods are rotatably installed on the inner side of the support frame. Two groups of guide rods are relatively arranged, and the outer peripheral surfaces are slidably connected to the inside of the movable plate.

[0011] Through the above technical solution, the drive motor is started, so that the rotor end of the drive motor rotates to drive the threaded rod to rotate. The threaded rod drives the movable plate on the outer peripheral surface to move when rotating. At the same time, the guide rod increases the stability of the movement of the movable plate. This structure facilitates the movement of the movable plate and thus moves the aerospace composite material fixed on the movable plate, so that it can adapt to drilling operations in different positions and improve the compatibility of the device.

[0012] Preferably, two groups of baffles are relatively fixedly installed on both sides of the top of the movable plate, and a screw rod is installed through the thread on the side of one group of baffles, and a push plate is fixedly and rotatably installed on the top of the screw rod through a bearing.

[0013] Through the above technical solution, first, one end of the aerospace composite material is abutted against the inner side of another set of baffles, and the screw is rotated to make the screw move threadedly on the side of one set of baffles. At the same time, the push plate is driven to move through the bearing until the push plate fixes and clamps the other end of the aerospace composite material, thereby increasing the stability of the aerospace composite material during the drilling process, avoiding deviation of the aerospace composite material during the drilling operation, and adapting to the processing of aerospace composite materials of different sizes.

[0014] Preferably, a group of grooves are opened inside the bottom end of the drill rod, a convex plate is embedded in the groove, a drill bit is fixedly installed on the bottom end of the convex plate, and multiple groups of first screw holes are opened on the side, and multiple groups of second screw holes are opened on the side of the drill rod corresponding to the first screw holes.

[0015] Through the above technical solution, the concave plate is embedded in the groove, so that the concave plate drives the drill bit to connect with the bottom end of the drill rod, and then the screw is nailed into the second screw hole, and the top end is nailed into the first screw hole, which is convenient for connecting the concave plate with the inside of the bottom end of the drill rod. At this time, the top end of the screw is embedded in the second screw hole. This structure is convenient for fixing the drill rod and the drill bit. At the same time, when the drill bit needs to be replaced, it is only necessary to disassemble the screw.

[0016] Preferably, a connecting plate is fixedly installed on the outer circumference of the drill pipe, a plurality of connecting rods are fixedly installed on the bottom end of the connecting plate, and a plurality of springs are fixedly installed on the bottom end near the outer circumference of the connecting rods, the inside of the springs is sleeved with the outer circumference of the connecting rods, and a sleeve plate is fixedly installed on the bottom end, and the outer circumference of the bottom end of the connecting rods is slidably connected with the inside of the sleeve plate.

[0017] Through the above technical solution, firstly, the sleeve covers the top of the second screw hole, thereby preventing some debris from entering the second screw hole during the drilling process and causing the screw to get stuck. When the screw needs to be removed, it is only necessary to slide the sleeve to make the sleeve rise to squeeze the spring. At the same time, the sleeve slides on the outer peripheral surface of the bottom end of the connecting rod to expose the position of the second screw hole and remove the screw. When the disassembly and installation is completed, the sleeve is loosened to release its tension, and the spring is reset to drive the sleeve to continue to cover the second screw hole. This structure provides shielding and protection for the screw installation.

[0018] Compared with the prior art, the utility model provides a drilling device with flexible drill bit replacement, which has the following beneficial effects:

[0019] 1. The utility model generates suction through the duct and the dust cover of the vacuum cleaner to absorb the splashed debris, which finally enters the vacuum cleaner through the dust cover and the duct and is then discharged into the drain groove through the output end of the vacuum cleaner, thereby increasing the effect of debris recovery during drilling.

[0020] 2. The utility model uses a screw rod to perform threaded movement on the side of one group of baffles, and at the same time drives the push plate to move through the bearing until the push plate fixes and clamps the other end of the aerospace composite material, thereby increasing the stability of the aerospace composite material during the drilling process, avoiding deviation during the drilling operation of the aerospace composite material, and adapting to the processing of aerospace composite materials of different sizes. The drive motor is started to rotate the rotor end of the drive motor to drive the threaded rod to rotate, and the threaded rod drives the movable plate on the outer peripheral surface to move when it rotates. At the same time, the guide rod increases the stability of the movement of the movable plate. This structure facilitates the movement of the movable plate and thus moves the aerospace composite material fixed on the movable plate, so that it can adapt to drilling operations at different positions and improve the compatibility of the device.

[0021] 3. The utility model embeds the concave plate into the groove so that the concave plate drives the drill bit to connect with the bottom end of the drill rod. Then, after the screw is nailed into the second screw hole, the top end is nailed into the first screw hole, which is convenient for connecting the concave plate with the inside of the bottom end of the drill rod. At this time, the top end of the screw is embedded in the second screw hole. This structure is convenient for fixing the drill rod and the drill bit. At the same time, when the drill bit needs to be replaced, it is only necessary to disassemble the screw. First, the sleeve plate blocks the top end of the second screw hole to avoid some debris entering the second screw hole during the drilling process and causing the screw to be stuck. When the screw needs to be removed, it is only necessary to slide the sleeve plate to make the sleeve plate rise to squeeze the spring. At the same time, the sleeve plate slides on the outer peripheral surface of the bottom end of the connecting rod to make the position of the second screw hole leak out and the screw is removed. When the disassembly and installation are completed, the sleeve plate is loosened to release its tension, and the spring is reset to drive the sleeve plate to continue to cover the second screw hole. This structure provides shielding and protection for the screw installation. BRIEF DESCRIPTION OF THE DRAWINGS
