[0032] The fixing mechanism 6 includes a disc 601, the bottom of which is slidably connected to both sides of the inner wall of the push block 5 through a slider, and push columns 602 are fixedly connected to both sides of the disc 601, and a telescopic box 604 is fixedly connected to the right side of the disc 601. A compression assembly 606 is provided at the bottom of the inner wall of the telescopic box 604, and a buffer tube 603 is fixedly connected to the left side of the disc 601. An adsorption pad 605 is fixedly connected to the top of the buffer tube 603. The buffer tube 603 has a telescopic function, and each telescopic movement will buffer the vibration generated by drilling.

[0033] The compression assembly 606 includes a telescopic disk 6061, a compression rod 6062 is slidably connected to the top slot of the telescopic disk 6061, a telescopic column 6063 is fixedly connected to the top of the compression rod 6062, a support disk 6066 is fixedly connected to the top of the telescopic column 6063, a connecting cavity 6065 is fixedly connected to the surface of the telescopic column 6063, an extrusion ring 6064 is fixedly connected to the bottom of the connecting cavity 6065, one end of the extrusion ring 6064 away from the connecting cavity 6065 is fixedly connected to the surface of the telescopic disk 6061, a telescopic airbag is installed inside the telescopic disk 6061, when squeezed by one end of the compression rod 6062, air pressure is generated and injected into the extrusion ring 6064, and a cavity is opened inside the extrusion ring 6064, and air pressure is injected into the connecting cavity 6065 through the internal cavity of the extrusion ring 6064, a compression ring 6067 is slidably connected to the top slot of the connecting cavity 6065, and a buffer assembly 607 is provided on the inner wall of the compression ring 6067.

[0034] The buffer assembly 607 includes a covering plate 6071, one end of which is fixedly connected to the inner wall of the compression ring 6067, a connecting tube 6072 is fixedly connected to the bottom of the end of the covering plate 6071 away from the compression ring 6067, and the connecting tube 6072 is fixedly connected to the left side of the disc 601. Contact arms 6074 are rotatably connected to the inner wall of the covering plate 6071 on both sides through a rotating shaft, and an adsorption film 6075 is fixedly connected to the surface of the contact arm 6074. The surface of the adsorption film 6075 is provided with absorption holes, and the adsorption film 6075 is made of a retractable characteristic material. When the adsorption film 6075 contacts the surface of the flange, the vibration generated will be absorbed and buffered. A pushing belt 6073 is fixedly connected to the right side of the contact arm 6074, and the end of the pushing belt 6073 away from the contact arm 6074 is fixedly connected to the bottom of the inner wall of the covering plate 6071.

[0035] The working method of the first embodiment is as follows: first, the flange is moved to the surface of the disc 601, and the flange is fixed by the adsorption pad 605. The right side of the flange will contact the surface of the support disc 6066. When drilling a hole on the surface of the flange, the left side of the flange will be vibrated and generate pressure on the inside of the buffer tube 603, and one end of the buffer tube 603 will expand and contract inward due to the pressure. While the buffer tube 603 expands and contracts inward, the vibration force generated by drilling the flange is buffered and absorbed. The multiple arranged adsorption pads 605 arranged on the left side of the flange can adsorb and fix flanges of different sizes. While fixing flanges of different specifications, it can also buffer and absorb the vibration force generated by drilling holes on their surfaces. When drilling is performed on the left side of the flange, its surface will vibrate violently, thereby pushing the support plate 6066 through the flange, so that the telescopic column 6063 at the bottom of the support plate 6066 receives pressure, thereby driving one end of the compression rod 6062 to slide toward the inside of the telescopic plate 6061, and compressing the internal space of the telescopic plate 6061 through one end of the compression rod 6062, so that the air pressure generated inside the telescopic plate 6061 is injected into the connecting cavity 6065 through the extrusion ring 6064, and the flange will compress the compression ring 6067 when vibrating, so that the compression ring 6067 is compressed toward the inside of the connecting cavity 6065, thereby squeezing the air pressure inside the connecting cavity 6065 into the cladding plate 6071 After the air pressure is injected into the pushing belt 6073 through the inside of the covering plate 6071, the pushing belt 6073 will be driven to expand and contract outward and push the contact arm 6074. After the multiple contact arms 6074 are tilted to the top, they will come into contact with the surface of the flange. When the surface of the flange is drilled, the vibration generated will be transmitted to the entire body of the flange. The three covering plates 6071 will cover the surface of the flange. When the surface of the flange is affected by the vibration force generated by the drilling, the vibration force will be absorbed by the multiple adsorption films 6075, which can absorb the vibration force transmitted to the entire body of the flange due to the drilling, and can also prevent the surface of the flange from being loosened from the surface of the fixing device due to the violent shaking caused by the drilling.

[0036] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The clamping mechanism 7 includes a clamping plate 701 fixedly connected to one end of the sliding block 2, the bottom of the clamping plate 701 is fixedly connected to the top of the working plate 1, a clamping groove 702 is provided on the right side of the clamping plate 701, a compression tube 703 is fixedly connected to the bottom of the inner wall of the clamping groove 702, and a contact assembly 704 is provided on the inner wall of the clamping plate 701.

[0037] The contact assembly 704 includes a movable block 7041 which is slidably connected to the inner wall groove of the clamping plate 701, the inner wall of the movable block 7041 is slidably connected to the movable block 7041, the surface of the movable block 7041 is fixedly connected to a compression membrane 7042, both sides of the inner wall of the movable block 7041 are fixedly connected to sliding rods 7043, the surface of the sliding rods 7043 is slidably connected to a buffer wheel 7044, an absorption cavity is provided inside the buffer wheel 7044, when the buffer wheel 7044 is subjected to external pressure and slides on the surface of the sliding rod 7043, the pressure transmitted from the outer ring of the flange is buffered, the compression membrane 7042 is fixedly connected to the contact plate 7045 at one end away from the movable block 7041, and the inner wall of the contact plate 7045 is fixedly connected to an absorption membrane 7046.

[0038] The working method of the second embodiment is as follows: when the flange is fixed on the surface of the disc 601, the disc 601 is pushed inward to slide on the inner wall of the pushing block 5. When the disc 601 drives the flange to move to the inside of the clamping disc 701, the pushing column 602 on the surface of the disc 601 moves to the inside of the clamping groove 702, and squeezes the compression tube 703 through one end of the pushing column 602, so that the compression tube 703 expands and contracts inwardly, thereby compressing the gas inside the compression tube 703 and discharging it into the inside of the clamping disc 701, thereby pushing the movable block 7041 inside the clamping disc 701 outward, thereby driving the movable block 7041 to move outward to the surface of the flange, and making contact with the outer ring of the flange through the absorption film 7046, thereby connecting the contact disc 7045 with the flange. When the surface of the flange is drilled, the vibration force generated by the drilling inside the flange will be transmitted to the inside of the flange. When the generated vibration pressure is transmitted to the outer ring through the inside of the flange, the absorption film 7046 will be compressed, thereby driving the compression film 7042 to be compressed inward. When the compression film 7042 expands and contracts inward, the buffer wheel 7044 inside it will be squeezed, so that the buffer wheel 7044 moves inside the compression film 7042. When the buffer wheel 7044 slides on the surface of the sliding rod 7043, the vibration pressure inside the flange will be buffered and diluted, thereby absorbing the vibration received by the inside of the flange during drilling, thereby avoiding cracks on the surface of the flange caused by the vibration generated by the drilling.

[0039] Embodiment 3: The difference from Embodiment 1 is as follows: Figure 7-Figure 8 The pushing mechanism 8 includes a positioning block 801, which is fixedly connected to the surface of the working box 4. The surface of the positioning block 801 is slidably connected to a shift disk 802. The inner wall of the shift disk 802 is fixedly connected to a telescopic rod 803. The end of the telescopic rod 803 away from the positioning block 801 is fixedly connected to a power box 804. The top of the power box 804 is fixedly connected to a compression disk 805. The inner wall of the power box 804 is provided with a stabilizing component 806.

[0041] The stabilizing component 806 also includes an ejection chamber 8068, which is fixedly connected to the surface of the cylinder 8061. When the interior of the cylinder 8061 is compressed by one end of the push rod 8063, the air pressure inside the ejection chamber 8068 will be ejected outward through the ejection hole on the surface of the ejection chamber 8068, thereby blowing out the debris generated by drilling inside the bolt hole. The surface of the cylinder 8061 is fixedly connected to an air intake chamber 8069, the left side of the air intake chamber 8069 is slidably connected to the inner wall of the power box 804, and the right side of the air intake chamber 8069 is fixedly connected to the surface of the ejection chamber 8068.

[0042] The working method of the second embodiment is as follows: when the remote start propeller 3 drives the working box 4 to slide on the inner wall of the sliding block 2, when the working box 4 is close to the surface of the flange, the power device inside the starting working box 4 drives the shift plate 802 to slide on the surface of the positioning block 801, and when the shift plate 802 slides on the surface of the positioning block 801 to the drilling position of the flange, the three-phase motor in the starting power box 804 drives the cylinder 8061 to rotate, and the telescopic device inside the starting working box 4 drives the telescopic rod 803 The grinding plate 8064 is extended outward and moves to the surface of the flange, and the surface of the flange is polished by one end of the grinding tube 8062 that is extended outward. When one end of the grinding tube 8062 is polished into the internal slot of the flange, when the grinding plate 8064 rotates to polish the internal bolt hole of the flange, the push rod 8063 inside the grinding tube 8062 will be extended to the inside of the grinding tube 8062 due to the grinding, and one end of the air inlet cavity 8069 is connected to the bottom air inlet hole of the compression disk 805 through the internal air cavity of the power box 804. Then, the internal air pressure of the compression disk 805 is connected to the air inlet chamber 8069, and the air pressure inside the compression disk 805 is injected into the cylinder 8061 through the air inlet chamber 8069. When one end of the push rod 8063 is extended inward, the air pressure inside the grinding tube 8062 is compressed, so that the air pressure is discharged outward and flows into the pop-up rod 8065, thereby driving the pop-up rod 8065 to extend outward and drive the contact pad 8066 to contact the inside of the bolt hole. When the grinding disc rotates and rubs the inside of the bolt hole, The intense friction force generated will be transmitted to the inside of the bolt hole. When the contact pad 8066 contacts the inside of the bolt hole, the pressure generated on the inside of the bolt hole will be transmitted to the inside of the absorption tube 8067 through the contact pad 8066. When the absorption tube 8067 is compressed inwardly, the pressure will be absorbed. The pressure generated on the inside of the bolt hole being polished on the flange surface can be absorbed, thereby preventing the intense friction on the inside of the bolt hole from causing cracks in the slot hole and affecting the polishing effect of the bolt hole.
