Abstract
Description
Technical Field
[0001] This utility model relates to a drilling measurement mechanism with self-cleaning function, belonging to the field of drilling measurement technology. Background Technology
[0002] During drilling, timely cleaning of debris inside the hole can prevent drill bit jamming, overheating, or affecting machining accuracy. Cleaning methods include: compressed air blowing, using an air gun or compressed air hose to blow air into the hole to quickly remove dry debris such as metal shavings and wood chips. Safety goggles should be worn to prevent debris from flying, and a long nozzle should be used for deep holes; brush or hook cleaning, using a long-bristled brush (such as a nylon brush) to reach into the hole and rotate to clean, or using a hook to pick out tangled debris, suitable for soft materials (such as plastics and wood) or shallow holes; and vacuum cleaner assistance, using an industrial vacuum cleaner with a long, thin nozzle to directly suck up debris, suitable for materials with a lot of dust (such as MDF boards and aluminum alloys).
[0003] Drilling is a common machining operation used to create circular holes in materials. To ensure drilling accuracy, measurements are required after drilling. Typically, a thin rod is inserted into the hole to measure the depth. However, debris that may be present in the hole can prevent the measuring rod from reaching the bottom smoothly, affecting measurement accuracy. The debris can also cause inconvenience in subsequent processing, making it difficult to clean the debris in the hole while measuring. Furthermore, burrs and other debris may remain on the edge after drilling. If these burrs are not cleaned later, they can easily fall into the hole, making it difficult to remove them and affecting subsequent processing. Utility Model Content

[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0030] like Figure 1-6 As shown, the self-cleaning drilling and measuring mechanism includes:
[0031] Platform 1, with a ring-shaped cover 15 fixedly connected to the bottom of the platform 1. A measuring rod 5 is inserted through the middle of the cover 15 and the platform 1. The measuring rod 5 is a hollow structure and has an inclined air outlet 6 at the bottom. The surface of the measuring rod 5 is provided with scale lines 9.
[0032] A collection box 10 is located on one side of the measuring rod 5 and is fixedly connected to the surface of the platform 1. The top of the collection box 10 is connected to the platform 1 through a guide pipe 13, and the guide pipe 13 extends into the inside of the cover 15. A housing 21 is movably fitted inside the cover 15. An external gear ring 22 is provided inside the housing 21. The top of the housing 21 is connected to the inside of the cover 15 through a buffer, and the bottom of the external gear ring 22 is fixedly connected to the grinding disc 24 through a support rod 23. The grinding disc 24 is in contact with the edge of the drill hole.
[0033] The platform 1 is equipped with adjustable support legs 2 around its bottom. A stabilizing sleeve 3 is fixedly connected to the top of the platform 1. A measuring rod 5 is movably fitted inside the stabilizing sleeve 3, and an indicator 4 corresponding to the scale line 9 is provided at the top of the stabilizing sleeve 3. An end 7 is fixedly connected to the top of the measuring rod 5. The end 7 is connected to the external pipe 8, and the measuring rod 5 is connected to an external air source through the external pipe 8.
[0034] In this technical solution, the adjustable support leg 2 is used to support the platform 1. When the platform 1 is placed on the workpiece surface, the gasket 16 at the bottom of the cover 15 contacts the workpiece surface to achieve a seal. The measuring rod 5 is inserted into the drill hole for measurement. At this time, the stabilizing sleeve 3 can ensure the stable movement of the measuring rod 5. After cleaning the debris in the hole, the bottom of the measuring rod 5 contacts the bottom of the hole. At this time, the value of the scale line 9 at the indicator 4 is read to measure the depth.
[0035] Specifically, the external pipe 8 is connected to an external air source, and the air source delivers gas through the external pipe 8 and the end 7 to the measuring rod 5, and blows it out at an angle from the air outlet 6 at the bottom of the measuring rod 5. At this time, the airflow disturbs the debris and blows it out of the borehole.
[0036] The collection box 10 has an inclined filter screen 12 fixedly connected inside. The guide pipe 13 is located above the filter screen 12. The collection box 10 located below the filter screen 12 is connected to the exhaust pipe. The side wall of the collection box 10 is rotatably connected to the box cover 11. Two retaining plates 14 are provided on one side of the box cover 11, and the retaining plates 14 are attached to the surface of the platform 1.
[0037] In this technical solution, the airflow carries debris from the guide pipe 13 into the collection box, where it is filtered by the filter screen 12 so that clean gas is discharged from the exhaust pipe at the bottom of the collection box 10. After cleaning is completed, the clamping plate 14 is rotated to separate it from the box cover 11. After opening the box cover 11, the debris on the surface of the filter screen 12 is discharged, making it convenient for cleaning.
[0038] A washer 16 is fixedly connected to the bottom of the cover 15. One side of the cover 15 has a U-shaped cross-section. A sealing ring 17 is fixedly connected to the inner wall of the cover 15, and the sealing ring 17 is sleeved on the surface of the measuring rod 5. The buffer consists of a guide sleeve 18 and a guide rod 19. The guide sleeve 18 is fixedly connected to the inside of the cover 15. The guide rod 19 is movably sleeved inside the guide sleeve 18. The top end of the guide rod 19 is connected to the inside of the guide sleeve 18 through a spring 20, and the bottom end of the guide rod 19 is fixedly connected to the housing 21. The housing 21 has an annular structure and is sleeved inside the cover 15. An external gear ring 22 is rotatably connected inside the housing 21, and a gap for the rotation of the support rod 23 is provided between the bottom of the housing 21 and the cover 15. A gear 28 is rotatably connected to one side of the housing 21, and the gear 28 meshes with the external gear ring 22.
[0039] In this technical solution, when the measuring rod 5 moves, it moves within the sealing ring 17 on the inner wall of the cover 15, which can ensure the sealing performance between the two. When the cover 15 is pressed against the surface of the workpiece, the grinding disc 24 is attached to the top edge of the hole. At this time, the guide rod 19 moves within the guide sleeve 18 and compresses the spring 20. The resulting force makes the grinding disc 24 fit against the edge of the drilled hole.
[0040] A motor 25 is fixedly installed on the top of the platform 1. The output end of the motor 25 is fixedly connected to the sleeve 26. A drive shaft 27 is movably sleeved inside the sleeve 26. The drive shaft 27 is rotatably connected to the inside of the housing 21, and the bottom end of the drive shaft 27 is fixedly connected to the gear 28. A rib 29 is fixedly connected to the surface of the drive shaft 27. The rib 29 is engaged and slides inside the groove opened on the inner wall of the sleeve 26.
[0041] In this technical solution, when the motor 25 drives the sleeve 26 to rotate, the groove of the sleeve 26 and the rib 29 cooperate to drive the transmission shaft 27 to rotate synchronously. The transmission shaft 27 drives the gear 28 to rotate on one side of the housing 21, and then drives the outer gear ring 22 to rotate inside the housing 21. The outer gear ring 22 drives the grinding disc 24 to rotate through the support rod 23, so that the grinding disc 24 grinds the edge of the drilled hole to remove burrs. The debris generated by removing burrs is discharged synchronously with the airflow to ensure the cleaning effect. When the grinding disc 24 drives the housing 21 to move, the housing 21 drives the transmission shaft 27 to rise and fall synchronously inside the sleeve 26, so as not to affect the transmission. When the height of the grinding disc 24 is different due to different hole diameters, the motor 25 can always drive the grinding disc 24 to perform the transmission function, and the drilled holes of different diameters can achieve the self-cleaning function.
