[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0033] Embodiment 1:

[0034] Please refer to Figures 1-9 , the present application discloses a drilling device for an anti-vibration automotive crossbeam bracket, including a base 1. A driving machine 2 is slidably installed on the top of the base 1. A clamping head 3 is installed on the side wall of one side of the driving machine 2. A drill bit is installed at one end of the clamping head 3. One end of the base 1 away from the driving machine 2 is fixedly connected to a bracket 5. A lifting arm 6 is slidably installed on the side wall of the bracket 5. A connecting arm 7 is installed on the lower side of the lifting arm 6. The bottom end of the connecting arm 7 is fixedly connected to an annular frame 8. A plurality of uniformly distributed hydraulic telescopic rods 16 are fixedly connected to the inner circle of the annular frame 8. The movable end of the hydraulic telescopic rod 16 is fixedly connected to a supporting wheel 1601. The drill bit is composed of a supporting drill section 4 and a drilling section 401. The supporting drill section 4 is set as a cylindrical shape with a smooth surface. Drill grooves are provided on the surface of the drilling section 401. The diameter of the drilling section 401 is larger than the diameter of the supporting drill section 4. Before drilling, the crossbeam is fixed between the driving machine 2 and the bracket 5. The lifting arm 6 drives the annular frame 8 to move between the two sides of the crossbeam, and the center point of the annular frame 8 and the center point of the drilling are on the same straight line. And when the plurality of hydraulic telescopic rods 16 contract, the diameter of the circle formed by the plurality of supporting wheels 1601 is larger than the diameter of the drilling section 401. When drilling, the driving machine 2 drives the drill bit to move towards the crossbeam. The drilling section 401 first drills through the left side of the crossbeam. When the drilling section 401 passes through the annular frame 8, the plurality of hydraulic telescopic rods 16 extend so that the supporting wheels 1601 contact the supporting drill section 4 to support it. Then the drilling section 401 continues to move to the right to drill through the right side of the crossbeam. After the hole is opened, the driving machine 2 moves to the left to take out the drill bit, and when the drilling section 401 passes through the annular frame 8, the hydraulic telescopic rods 16 contract to avoid affecting it. Compared with the traditional drilling method, it can support the drill bit during drilling, largely avoiding the vibration of the drill bit due to eccentricity or other reasons, and at the same time improving the drilling accuracy.

[0035] Embodiment 2:

[0036] Among them, the same or corresponding components as in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0037] Please refer to Figures 5-9, a top plate 10 is fixedly connected to the side wall of the driving machine 2 close to the support 5. The connecting arm 7 is slidably connected to the lifting arm 6. A vertical plate is fixedly connected to the bottom end of the lifting arm 6. A spring ejector rod 701 is fixedly connected between the connecting arm 7 and the vertical plate. When the support wheel 1601 contacts the support drill section 4 to fasten it, the top plate 10 is in contact with the connecting arm 7. When the driving machine 2 continues to drive the drill bit to move to the right, it will push the connecting arm 7 through the top plate 10, driving the ring frame 8 to move to the right, so that the support wheel 1601 can move with the movement of the drill bit, enabling the support wheel 1601 to better support the drill bit.

[0038] Please refer to Figures 5-9 , one end of the lifting arm 6 is fixedly connected to an upper pipe 11. A lifting rod 13 is slidably connected through the bottom end of the upper pipe 11. A roller 14 is fixedly connected to the bottom end of the lifting rod 13. A distance sensor 12 is fixedly connected to the inner wall of the top end of the upper pipe 11. The distance sensor 12 is used to control the expansion and contraction of the hydraulic telescopic rod 16.

[0039] Please refer to Figures 5-9 , the top plate 10 is composed of a left drop plate 1001 and a right drop plate 1002. The left drop plate 1001 is close to the driving machine 2, and the right drop plate 1002 is far from the driving machine 2. The thickness of the left drop plate 1001 is greater than that of the right drop plate 1002, and the connection between the left drop plate 1001 and the right drop plate 1002 is inclined. Before drilling the cross beam, the bottom end of the roller 14 contacts the right drop plate 1002. At this time, the reading of the distance sensor 12 is large, and the hydraulic telescopic rod 16 is in a contracted state. When the driving machine 2 drives the drill bit to break through the left side of the cross beam and pass through the ring frame 8, the left drop plate 1001 contacts the roller 14 and the lifting rod 13 is lifted. At this time, the reading of the distance sensor 12 is small, and the hydraulic telescopic rod 16 is controlled to extend so that the support wheel 1601 is in close contact with the support drill section 4 to support it. Through the above settings, the expansion and contraction of the hydraulic telescopic rod 16 can be controlled.

[0040] Please refer to Figure 1 and 10-11. A sensing box 9 is fixedly connected to the top end of the driving machine 2. The interior of the sensing box 9 is filled with vibration sensing liquid which is made of transparent material. An installation groove is formed through the bottom end of the sensing box 9, and a light-transmitting block 901 is fixedly connected to the interior of the installation groove. A laser emitter 15 is fixedly connected to the bottom end of the sensing box 9 near the light-transmitting block 901, and the light emitted by the laser emitter 15 can pass through the light-transmitting block 901. An alarm is fixedly connected to the top end of the sensing box 9. A plurality of annularly distributed light sensors 17 are fixedly connected to the inner wall of the top end of the sensing box 9. The center of the circle formed by the plurality of light sensors 17 is on the same straight line as the center point of the laser emitter 15. The plurality of light sensors 17 are all electrically connected to the alarm. When the vibration of the driving machine 2 is relatively low, the surface of the vibration sensing liquid shakes slightly, and the light emitted by the laser emitter 15 cannot be sensed by the light sensors 17. When the vibration of the driving machine 2 is relatively large, the surface of the vibration sensing liquid shakes violently, refracting the light emitted by the laser emitter 15. At this time, the light sensors 17 on the inner photosensitive device receive the light, sending an electrical signal to the light sensors 17 to make it emit an alarm. Through the above settings, the driving machine 2 can be vibration-sensed, and a timely reminder can be given when the driving machine 2 vibrates.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its improved concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
