Description

Technical Field

[0001] This invention belongs to the technical field of hole-making methods and relates to an instrument and method that can achieve rapid, detachable, and vertical hole-making with chip suction. Background Technology

[0002] In actual production assembly, hole-making is required for the assembly of components made of composite materials, aluminum alloys, titanium alloys, etc., and the quality of hole-making and the on-site operating environment are becoming increasingly stringent. When manual operation is required, the smooth removal of debris during hole-making is crucial to product quality and the working environment. Currently, most workers on the production line rely on the threaded drill bit itself to remove debris during hole-making. This method has certain drawbacks: 1) The inability to remove debris from the hole in time can scratch the hole wall, affecting the hole-making quality; 2) The debris during hole-making of glass fiber composite materials and carbon fiber composite materials is very fine, posing a significant health hazard to on-site operators if inhaled; 3) The hole-making process is greatly affected by the operator's skill level, making it impossible to guarantee the perpendicularity of the hole; 4) In some enclosed areas, the debris cannot be directly removed during hole-making operations, failing to meet the requirements for excess material control on the assembly site. The portable, quick-release, and detachable debris-collecting hole-making device described in this invention can improve product quality and the on-site operating environment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a portable, fast and detachable chip removal hole-making device and method, which can remove debris during the hole-making process of different hole diameters and different materials, and solves the technical problems existing in the prior art such as poor hole-making quality, limited hole-making in enclosed spaces, and strict requirements for the assembly site environment.

[0004] To solve the above problems, the specific technical solution of the present invention is as follows:

[0005] A portable, quick-release, detachable chip suction and hole-making device includes a chip removal conduit 1, a flexible hose 2 and a slider 3 placed inside the chip removal conduit, and an air source connector 4 placed on the chip removal conduit 1; a vertical drill 5 is screwed to the front end of the chip removal conduit 1, and a detachable bushing 6 of various hole diameters is screwed into the vertical drill 5.

[0006] The chip removal conduit 1 has a hollow structure, and its inner wall has two different diameter holes: a large-diameter hole and a small-diameter hole. A vertical drill 5 is installed at one end of the large-diameter hole (the rear end of the chip removal conduit 1), and a flexible hose 2 is inserted into the chip removal conduit 1 at the end of the small-diameter hole (the front end of the chip removal conduit 1). The flexible hose 2 and a slider 3 are arranged inside the chip removal conduit 1. The slider 3 is positioned inside the large-diameter hole and at the front end of the small-diameter hole. A through hole is opened in the wall of the large-diameter hole to connect with the air source connector 4.

[0007] The slider 3 is a hollow, conical structure placed inside the large-diameter hole of the chip removal conduit 1. One end of the slider 3 is the large-diameter end, with a stepped protrusion whose diameter is larger than the diameter of the small-diameter hole in the chip removal conduit 1 but smaller than the diameter of the large-diameter hole, ensuring that the slider 3 is always at the top of the inner wall of the small-diameter hole in the chip removal conduit 1; the other end of the slider 3 is the small-diameter end, which can fit into the flexible hose 2. The maximum outer diameter of the slider 3 is larger than the inner diameter of the flexible hose 2, and the minimum outer diameter is smaller than the inner diameter of the flexible hose 2.

[0008] The outer diameter of the hose 2 is smaller than the large inner diameter of the chip removal conduit 1 and larger than the small inner diameter of the chip removal conduit 1. It is inserted into the large hole end of the chip removal conduit 1 for a tight fit, and is clearance-fitted with the slider 3.

[0009] The air source connector 4 is a hollow structure that communicates with the chip removal conduit 1 and is positioned within the through hole in the wall of the large bore of the chip removal conduit 1. The air source connector 4 and the chip removal conduit 1 are connected by threads. Different air source connectors 4 can be used depending on the material of the workpiece being drilled.

[0010] The vertical drill 5 has a threaded hole on one side that penetrates the hole wall and is connected to the rear end of the chip removal guide 1 by a thread; the top of the vertical drill 5 has a blind hole for installing a removable bushing 6, wherein the removable bushing 6 has a central through hole and the hole diameter is adjustable.

[0011] In use, the bushing 6 is connected to the vertical drill 5, which is screwed to the chip removal conduit 1. One end of the vertical drill 5 is fitted to the part to be drilled and ensures verticality. The air source connector 4 is connected via a snap-fit ​​mechanism. Gas enters the inner wall of the large-diameter hole in the chip removal conduit 1 from the air source connector 4. Due to the conical shape of the slider 3, the gas will be discharged from the hose 2, creating a low-pressure environment inside. The slider 3 is then aligned to ensure it is parallel to the central axis of the hose 2. A through-hole is formed inside the chip removal conduit 1, hose 2, and slider 3. This device can remove debris when drilling with a drilling tool. Furthermore, the vertical drill 5 is threaded, allowing for the installation of a corresponding removable bushing 6 according to different hole diameters.

[0012] A method of using a portable, quick-release, detachable chip-collecting and hole-making device includes the following steps:

[0013] 1) Select a suitable removable bushing 6 according to the hole diameter of the part to be drilled;

[0014] 2) Screw the removable bushing 6 to the vertical drill 5 and install it onto the chip removal guide 1, while adjusting its position and angle;

[0015] 3) Install the air source onto the air source connector 4;

[0016] 4) Gas enters the inner wall of the large-diameter hole of the chip removal duct 1 from the air source connector 4;

[0017] 5) Due to the conical shape of slider 3, gas will be discharged from hose 2, creating a low pressure inside;

[0018] 6) Slider 3 will be moved and aligned to ensure that it is parallel to the central axis of hose 2;

[0019] 7) Use a hole-making tool to insert the vertical drill 5 through the removable bushing 6 to complete the hole making. The portable quick and removable chip suction hole-making device completes the hole making. The negative pressure formed at the outlet of the hose 2 causes the chips generated in the vertical drill 5 to be discharged in sequence through the small diameter hole of the chip discharge guide 1, the slider 3, and the hose 2.

[0020] The beneficial effects of this invention are as follows:

[0021] 1) This portable, quick-release, detachable chip removal and hole-making device can be freely adapted to different hole diameters and different part materials, ensuring smooth chip removal during the hole-making process in enclosed areas. This not only improves product quality but also improves the on-site environment.

[0022] 2) This method is simple in principle, compact in structure, and highly practical. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1As shown, a portable, quick-release, detachable chip suction and hole-making device is described. A flexible tube 2 and a slider 3 are sequentially arranged inside a chip removal conduit 1, with the slider 3 and tube 2 using a clearance fit. The inner wall of the chip removal conduit 1 has two different diameters. The slider 3 is positioned at the front end of the smaller diameter inner wall, while the larger diameter side has an opening connected to an air source connector 4. During use, gas enters the chip removal conduit 1 from the air source connector 4, creating a low-pressure environment inside. The slider 3 is aligned to ensure it is parallel to the central axis of the tube 2, allowing for chip suction during hole making.

[0030] The chip removal conduit 1 has a hollow structure, and its inner wall has two different diameter holes: a large-diameter hole and a small-diameter hole. A vertical drill 5 is installed at one end of the large-diameter hole (the rear end of the chip removal conduit 1), and the flexible hose 2 is inserted into the chip removal conduit 1 at the end of the small-diameter hole (the front end of the chip removal conduit 1). The flexible hose 2 and a slider 3 are arranged inside the chip removal conduit 1. The slider 3 is placed inside the large-diameter hole and located at the front end of the small-diameter hole. A through hole is opened in the wall of the large-diameter hole to connect with the air source connector 4. The slider 3 has a hollow, conical structure and is placed inside the inner wall of the large-diameter hole of the chip removal conduit 1. One end of the slider 3 is the large-diameter end, with a stepped protrusion whose diameter is larger than the diameter of the small-diameter hole but smaller than the diameter of the large-diameter hole, ensuring that the slider 3 is always at the top of the inner wall of the small-diameter hole of the chip removal conduit 1. The other end of the slider 3 is the small-diameter end, which can fit inside the flexible hose 2. The maximum outer diameter of the slider 3 is larger than the inner diameter of the flexible hose 2, and the minimum outer diameter is smaller than the inner diameter of the flexible hose 2. The outer diameter of the flexible hose 2 is smaller than the large inner diameter of the chip removal conduit 1, but larger than the small inner diameter of the chip removal conduit 1. It is inserted into the large hole end of the chip removal conduit 1 for a tight fit, and has a clearance fit with the slider 3. The air source connector 4 is a hollow structure that communicates with the chip removal conduit 1 and is located in the through hole in the wall of the large hole of the chip removal conduit 1. The air source connector 4 and the chip removal conduit 1 are connected by threads. Different air source connectors 4 can be replaced according to the material of the workpiece being drilled. The vertical drill 5 has a threaded hole on one side that penetrates the hole wall and is connected to the rear end of the chip removal conduit 1 by threads. The top of the vertical drill 5 has a blind hole for installing a removable bushing 6, wherein the removable bushing 6 has a central through hole with an adjustable diameter.

[0031] In use, the bushing 6 is connected to the vertical drill 5, which is screwed to the chip removal conduit 1. One end of the vertical drill 5 is fitted to the part to be drilled and ensures verticality. The air source connector 4 is connected via a snap-fit ​​mechanism. Gas enters the inner wall of the large-diameter hole in the chip removal conduit 1 from the air source connector 4. Due to the conical shape of the slider 3, the gas will be discharged from the hose 2, creating a low-pressure environment inside. The slider 3 is then aligned to ensure it is parallel to the central axis of the hose 2. A through-hole is formed inside the chip removal conduit 1, hose 2, and slider 3. This device can remove debris when drilling with a drilling tool. Furthermore, the vertical drill 5 is threaded, allowing for the installation of a corresponding removable bushing 6 according to different hole diameters.

[0032] like Figure 4 As shown, a method of using a portable, quick-release, detachable chip suction and hole-making device includes the following steps:

[0033] 1) Select an inner bushing that matches the required hole diameter;

[0034] 2) Screw the removable bushing to the vertical drill and install it onto the chip removal guide, while adjusting the position and angle of the vertical drill relative to the surface of the part to be drilled.

[0035] 3) Depending on the material of the part to be drilled, such as composite materials, select a lower air pressure connector; if it is aluminum alloy, select a higher air pressure connector. The air source is connected to the air source connector via a snap-fit ​​mechanism, and the gas enters the inner wall of the large-diameter hole in the chip removal duct from the air source connector.

[0036] 4) Based on the conical shape of the slider, the gas will be discharged from the hose, and a low pressure will be formed inside. At this time, the slider will also move and align itself to ensure that it is parallel to the central axis of the hose. At this time, a through hole will be formed inside the chip removal guide, the slider, and the hose.

[0037] 5) Use a hole-making tool to insert a vertical drill bit through a removable bushing to complete the hole making. A portable, quick, and removable chip-collecting hole-making device completes the hole making. The negative pressure formed at the outlet of the hose causes the chips generated during hole making in the vertical drill bit to be discharged sequentially through the small-diameter hole of the chip discharge guide, the slider, and the hose.
