[0015] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0016] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0017] In a specific embodiment, Figure 1-2As shown, an automatic loading type steel pipe punching machine includes a base plate 1, a hydraulic cylinder 2 is fixedly mounted on the base plate 1, a motor 3 is fixedly mounted on the driving end of the hydraulic cylinder 2, a drilling member 4 is connected to the driving shaft of the motor 3, a first linear module 5 is fixedly mounted on the base plate 1, a rotary fixture 6 for fixing the steel pipe is fixedly mounted on the driving end of the first linear module 5; that is, after the steel pipe is clamped by the rotary fixture 6, the position of the steel pipe is moved by the first linear module 5, the rotary fixture 6 is rotated and adjusted to face the drilling member 4 to be drilled, and the hydraulic cylinder 2 drives the motor 3 to descend to drive the drilling member 4 to descend and contact the steel pipe for rotary drilling.

[0018] It also includes two fixed plates 7 with fixed positions, a rotating plate 8 is installed at the bottom of the fixed plate 7, the spacing between the two rotating plates 8 is greater than the diameter of the steel pipe to be processed and less than twice the diameter of the steel pipe to be processed, a limiting plate 10 is fixedly installed at the bottom of the rotating plate 8, and a second linear module 11 is embedded in the bottom plate 1 and is located between the two rotating plates 8. The driving end of the second linear module 11 is fixedly connected to a driving column 12; that is, the steel pipes that need to be punched can be put into batches between the two fixed plates 7 and the two rotating plates 8, so that the steel pipes fall onto the bottom plate 1 one at a time by gravity, and the driving column 12 is initially located on the side of the steel pipe. The second linear module 11 drives the driving column 12 to move, and the driving column 12 can push the steel pipe into the rotating fixture 6 to be clamped by the rotating fixture 6 to complete the loading.

[0019] In this embodiment, the number of the second linear modules 11 is two, and the spacing between the two second linear modules 11 is smaller than the diameter of the steel pipe, ensuring that the two second linear modules 11 can drive the steel pipe to move at the same time, and the two second linear modules 11 run synchronously to prevent the driving column 12 from not being located on the vertical center axis of the steel pipe when one second linear module 11 pushes the steel pipe, causing the angle of the steel pipe to change during pushing.

[0020] In this embodiment, it also includes a pair of positioning mechanisms 13, and the positioning mechanism 13 includes a cylinder 131 and a push plate 132. The cylinder 131 is fixed on the base plate 1, and the push plate 132 is fixed to the driving end of the cylinder 131. The two push plates 132 of the pair of positioning mechanisms 13 have opposite sides with concave arc surfaces. After the steel pipe falls on the base plate 1, it is located between the two push plates 132. The two cylinders 131 run synchronously to drive the two push plates 132 to approach each other, thereby pushing the steel pipe to adjust the angle and position of the steel pipe, so that the second linear module 11 can accurately push the steel pipe into the rotating fixture 6.

[0021] In this embodiment, the rotating plate 8 is rotatably connected to the fixed plate 7, and two active telescopic rods 14 are rotatably connected to the base plate 1. The two active telescopic rods 14 are rotatably connected to the opposite sides of the two limit plates 10 respectively. Two through holes 15 are provided on the base plate 1, and the bottom of the limit plate 10 extends into the through holes 15; when the rotating plate 8 rotates, the limit plate 10 can move in the through holes 15 without being stuck, that is, when the two active telescopic rods 14 are extended, the distance between the two rotating plates 8 is reduced, and vice versa, the distance is increased, thereby adapting to steel pipes of various specifications and sizes.

[0022] The above automatic feeding steel pipe punching machine can be further optimized and / or improved according to actual needs:

[0023] There are multiple pairs of positioning mechanisms 13, one pair of positioning mechanisms 13 corresponds to one or several sizes of steel pipes, and different sizes of steel pipes are processed using positioning mechanisms 13 of different specifications for position calibration. In other embodiments, the two push plates 132 of a pair of positioning mechanisms 13 can also be straight plates, which can be adapted to steel pipes of various sizes.

[0024] Side plates 9 are fixedly installed on both sides of the two fixing plates 7 to prevent the steel pipe from sliding down in the length direction when the steel pipe is placed between the two fixing plates 7 .

[0025] To sum up: by temporarily storing the steel pipes to be punched between the two fixed plates 7 and the two rotating plates 8, the steel pipes are allowed to fall between the two limit plates 10 one at a time, and the second linear module 11 drives the driving column 12 to push the fallen steel pipe to the bottom of the drilling member 4 and insert it into the rotating fixture 6 for fixation, which can replace manual loading. The first linear module 5 drives the rotating fixture 6 to move, and the rotating fixture 6 drives the steel pipe to rotate, so as to move and rotate the position to be punched to the bottom of the drilling member 4, and then drilling can be carried out. The loading process does not require manual participation, and the manual handling of the steel pipe for loading is eliminated, which saves time and effort, and greatly improves the efficiency of steel pipe drilling.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
