However, it should be understood that these practical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0024] See also Figure 1-6 The utility model provides a thin-walled pipe deformation prevention surface drilling fixture, including a base plate 1, a vertical plate 2 is fixedly provided on one side of the top of the base plate 1, a driving assembly 3 is provided on one side of the vertical plate 2, the driving assembly 3 is transmission-connected with an upper support assembly 4 and an inner support assembly 5 used in conjunction with it, the upper support assembly 4 includes a movable seat 401, both sides of the bottom of the movable seat 401 are fixed with electric push rods 402, the bottoms of the two electric push rods 402 are fixed with upper support blocks 408, both sides of the inner cavity of the upper support block 408 are fixed with third micro air pumps 406, the output end of the third micro air pump 406 is connected to the third air bag 407, and the third air bag 407 is fixed to the bottom of the upper support block 408, one side of the third air bag 407 is connected to the upper elastic support plate 403, and the inner cavity of the movable seat 401 is fixed with a drill rod guide sleeve 405.

[0025] When supporting the outside of the pipe fitting, the two electric push rods 402 are started, and the upper support block 408 is driven to move downward by the two electric push rods 402. The downward movement of the upper support block 408 drives the two third micro air pumps 406, the third air bag 407 and the upper elastic support plate 403 to move downward. When the upper support block 408 moves downward until its bottom contacts the surface of the pipe fitting, the third micro air pump 406 is started, and the third air bag 407 is inflated by the third micro air pump 406. The upper elastic support plate 403 is driven to move by inflating the third air bag 407. When the upper elastic support plate 403 moves to fit tightly with the pipe fitting, the outer wall of the pipe fitting can be supported, avoiding the risk of deformation of the pipe fitting when downward pressure is applied.

[0026] The inner support assembly 5 includes an inner support body 501, and a cavity 502 is provided at the top and bottom of the inner cavity of the inner support body 501. The inner cavity of the cavity 502 is movably equipped with an inner support block 505. By setting two inner support blocks 505 to support the pipe fittings from the inside, it can play a role in assisting the positioning and fixation of the pipe fittings. The inner cavity of the upper support block 408 and the top inner support block 505 are respectively provided with a through hole 404 and a groove 509 corresponding to the drill rod guide sleeve 405. A second micro air pump 507 is fixed on both sides of the top and bottom of the inner support body 501, and the output ends of the four second micro air pumps 507 are connected to the second airbag 506. The second airbag 506 is fixed on the side surface of the inner support block 505, and one end of the four second airbags 506 is connected to the inner elastic support plate 508. A clamping assembly 6 is provided on the top of the base plate 1.

[0027] A first micro air pump 503 is fixedly installed in the inner cavity of the two cavities 502 . The output end of the first micro air pump 503 is connected to the first air bag 504 , and one end of the inner support block 505 is connected to the first air bag 504 .

[0028] When providing internal support to the pipe fitting, the first micro air pump 503 inflates the first air bag 504. The inflated first air bag 504 drives the inner support block 505 to move, and the inner support block 505 moves and contacts the inner wall of the pipe fitting. Then, the second micro air pump 507 inflates the second air bag 506. The inflated second air bag 506 drives the inner elastic support plate 508 to move. When the inner elastic support plate 508 fits tightly with the inner wall of the pipe fitting, support can be formed for the inner wall of the pipe fitting. By setting four inner elastic support plates 508 to fit with the inner wall of the pipe fitting, the pressure can be reduced, avoiding the situation where the inner support block 505 contacts the inner wall of the pipe fitting, and the pressure generated is large due to the small contact area, which easily causes indentations or damage to the inner wall of the pipe fitting.

[0029] By the joint action of the upper support assembly 4 and the inner support assembly 5 on the pipe fitting, the pipe fitting can be supported from both the outside and the inside. At the same time, the upper elastic support plate 403 and the inner elastic support plate 508 are used to limit the contour of the pipe fitting, thereby increasing the support effect on the pipe fitting, thereby improving the anti-deformation effect of the pipe fitting during drilling. Through the cooperation of the second airbag 506 and the second micro air pump 507, the third micro air pump 406 and the third airbag 407, when processing pipe fittings of different diameters, the upper elastic support plate 403 and the inner elastic support plate 508 can stably fit the inner and outer walls of the pipe fitting, and the drilling work can be carried out smoothly.

[0030] The driving assembly 3 includes a mounting base 301, one side of the mounting base 301 is fixedly connected to one side of the vertical plate 2, the inner cavity of the mounting base 301 is fixedly provided with a driving motor 302, one end of the driving motor 302 is rotatably connected to a rotating rod 303, the surface of the rotating rod 303 is fixedly sleeved with two driving sprockets 304 in sequence, the surfaces of the two driving sprockets 304 are meshed with transmission chains 305, one end of the two transmission chains 305 is meshed with a driven sprocket 306, the inner cavities of the two driven sprockets 306 are respectively fixed with an upper screw 307 and an inner screw 308, and one end of the upper screw 307 and the inner screw 308 both penetrate and extend to the other side of the vertical plate 2, the surfaces of the upper screw 307 and the inner screw 308 are respectively threaded with an upper screw sleeve 309 and an inner screw sleeve 310, the movable seat 401 and the inner support body 501 are respectively fixedly sleeved on the surfaces of the upper screw sleeve 309 and the inner screw sleeve 310.

[0031] When adjusting the drilling position, the upper elastic support plate 403, the upper support block 408, the inner support block 505 and the inner elastic support plate 508 retract, and then the drive motor 302 is started, and the rotating rod 303 is driven to rotate by the drive motor 302, and the two driving sprockets 304 are driven to rotate by the rotation of the rotating rod 303, and the two driving sprockets 304 drive the two transmission chains 305 to drive, and the two driven sprockets 306 are driven to rotate by the two transmission chains 305, and the upper screw 307 and the inner screw 308 are driven to rotate by the rotation of the two driven sprockets 306.

[0032] Sliding sleeves 313 are fixed on both sides of the inner cavity of the inner support body 501, and the inner cavities of the two sliding sleeves 313 are slidably connected to sliding rods 314, and one end of the two sliding rods 314 is fixedly connected to the other side of the vertical plate 2. A movable sleeve 311 is fixed on one side of the inner cavity of the movable seat 401, and the inner cavity of the movable sleeve 311 is slidably connected to a guide rod 312, and one end of the guide rod 312 is fixedly connected to the other side of the vertical plate 2.

[0033] By setting the guide rod 312 and the sliding rod 314, the movement of the movable seat 401 and the inner support body 501 can be limited, so that the movable seat 401 and the inner support body 501 cannot rotate, and then when the upper screw 307 and the inner screw 308 rotate, the upper screw sleeve 309 and the inner screw sleeve 310 can be driven to move. The upper screw sleeve 309 and the inner screw sleeve 310 move to drive the movable seat 401 and the inner support body 501 to move, and the movable seat 401 and the inner support body 501 can be adjusted to the required drilling position. Through the cooperation of the driving component 3, the movable seat 401, the drill rod guide sleeve 405 and the inner support body 501 can be made to move synchronously, so that the positions of the through hole 404, the drill rod guide sleeve 405 and the groove 509 always correspond, thereby ensuring the continuity of the drilling work and improving the drilling efficiency.

[0034] The length, pitch and thread direction of the upper screw 307 and the inner screw 308 are consistent, and the length of the guide rod 312 and the two sliding rods 314 are consistent.

[0035] The clamping assembly 6 includes two fixing seats 601, which are symmetrical and fixed on both sides of the top of the base plate 1. The inner cavities of the two fixing seats 601 are fixed with cylinders 602, and one end of the two cylinders 602 is fixed with a clamping plate 603.

[0036] When clamping the pipe fitting, the cylinder 602 is started, and the clamping plate 603 is driven to move by the cylinder 602. When the clamping plate 603 moves to be in close contact with the pipe fitting, the pipe fitting can be clamped and fixed. The clamping assembly 6 is arranged to cooperate with the upper elastic support plate 403 and the inner elastic support plate 508 to support and fix the pipe fitting, thereby ensuring the stability of the pipe fitting during the drilling process. At the same time, pipe fittings of different diameters can be clamped, which increases the flexibility of the clamp.

[0037] There are two clamping components 6 , and the clamping plates 603 in the clamping components 6 are made of elastic material.

[0038] By setting up two clamping assemblies 6 to fix the pipe fittings, the stability of the pipe fittings during the drilling process is further ensured. At the same time, the clamping plate 603 is made of elastic material, which can effectively fit and clamp pipe fittings of different diameters while avoiding damage to the pipe fittings.

[0039] The four inner elastic support plates 508 , the two upper elastic support plates 403 and the four clamping plates 603 are all in contact with the pipes at arc surfaces, and the four inner elastic support plates 508 , the two upper elastic support plates 403 and the four clamping plates 603 are in close contact with the pipes.

[0040] By performing arc surface treatment on the contact points between the inner elastic support plate 508, the upper elastic support plate 403 and the clamping plate 603 and the pipe fitting, damage to the inner and outer walls of the pipe fitting can be avoided during the supporting process of the pipe fitting, and damage to the surface of the pipe fitting can be avoided during the clamping process of the pipe fitting.

[0041] When using the present invention: first, the pipe to be processed is sleeved on the outer surface of the inner support assembly 5, and then the cylinder 602 drives the clamping plate 603 to move and clamp the pipe. Then, according to the drilling requirements, the driving assembly 3 drives the upper support assembly 4 and the inner support assembly 5 to move synchronously to the required drilling position, and then drives the inner support block 505 to move and contact the inner wall of the pipe, and drives the upper support block 408 to move downward and contact the outer wall of the pipe, so that the pipe can be supported from both the inside and the outside, and then drives the inner elastic support plate 508 to move and fit closely with the inner wall of the pipe, and the upper elastic support plate 403 to move and fit closely with the outer wall of the pipe, thereby realizing the limitation of the pipe contour and preventing the pipe from deformation during drilling.

[0042] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
