[0002] Steel pipe is a tubular product made of steel, widely used in construction, machinery manufacturing, transportation, energy and other industries. According to different purposes and manufacturing processes, steel pipes can be divided into many types, such as seamless steel pipes, welded steel pipes, galvanized steel pipes, etc.
[0003] In steel pipe processing, punching is a common process. According to the specific application requirements, the steel pipe may need to be punched for connection, installation or other functions. In some lightweight design, punching can help reduce the weight of the steel pipe. When punching the steel pipe, the steel pipe is usually moved under the punching drill bit and moved or rolled to punch the pipe body of the steel pipe. The punching device is mostly fixed due to its size. When punching some long or heavy steel pipes or fixed multiple rows of steel pipes, the punching device is not convenient to use, and manual handling is required, which consumes manpower. The heavy steel pipe and the fixed steel pipe make it difficult to transport, which increases the working intensity of the on-site workers and takes time. SUMMARY

DETAILED DESCRIPTION
[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0021] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] Please see Figs. 1-3 The device shown is a rapid drilling device for steel pipe processing, including a worktable 1, a fixed shaft 2 on the worktable 1, a base 3 above the fixed shaft 2, a base bearing 3a between the base 3 and the fixed shaft 2, a fixed frame 4 at one end of the base 3, the fixed frame 4 including a left support 4a and a right support 4b, a support shaft 4c between the left support 4a and the right support 4b, a connecting rod 5 between the left support 4a and the right support 4b, the two ends of the connecting rod 5 being sleeved on the support shaft 4c, a cylinder 6 on one side of the left support 4a, collars 6a at both ends of the cylinder 6, a cylinder connecting rod 7 at the bottom of the left support 4a and the top of the connecting rod 5, the collars 6a being sleeved on the cylinder connecting rod 7, a drilling machine 8 at the bottom of the right support 4b, and a connecting seat 9 on the body of the drilling machine 8.
[0023] A cross roller bearing is provided between the left support frame 4a and the base 3. The left support frame 4a is connected to the worktable 1 through the cross roller bearing. The base 3 is embedded with the cross roller bearing, and the bottom of the left support frame 4a is fixedly connected to one side of the cross roller bearing. This allows the left support frame 4a to rotate through the cross roller bearing and drive the entire fixed frame 4 to rotate. The right support frame 4b works on the same principle, except that the cross roller bearing is embedded in the bottom of the right support frame, and the connecting seat 9 is fixedly connected to one side of the cross roller bearing. This allows the drilling machine 8 to rotate around the cross roller bearing through the connecting seat 9. In use, the direction can be changed and the machine rotated by holding the handle of the drilling machine 8.
[0024] Please see Fig. 3A connecting rod 5 has a connecting piece 10 near the cylinder 6. The connecting piece 10 is L-shaped, and the cylinder connecting rod 7 at the top of the connecting rod 5 is embedded in the connecting piece 10. The connecting rod 5 rotates via the support shaft 4c. When the handheld drilling machine 8 moves up and down, the right support frame 4b also moves up and down accordingly. The up and down movement of the right support frame 4b will drive one end of the connecting rod 5 to move. When the end of the connecting rod 5 near the right support frame 4b rises, the end of the connecting rod 5 near the left support frame 4a will lower, and vice versa, which is a lever change. When the end of the connecting rod 5 near the left support frame 4a moves up and down, it will drive the connecting piece 10 to move. The drilling machine 8 moves up and down, and in order to obtain the stroke of the movement, the connecting piece 10 will bring out or press back the cylinder extension end of the cylinder 6 through the cylinder connecting rod 7. This allows the drilling machine 8 to increase or reset its stroke through the cylinder 6 when moving up and down, so that it will not be unable to move up and down. The rotation of the drilling machine 8 is achieved through the cross roller bearing. At the same time, the tilting and rotation of the cylinder 6 during the up and down movement are achieved through the bottom cylinder connecting rod 7. The collar 6a at the bottom of the cylinder 6 rotates around the bottom cylinder connecting rod 7, and the collar 6 at the top rotates around the top cylinder connecting rod 7.
[0025] The right support 4b and the connecting seat 9 are also connected by a cross roller bearing. The drilling machine 8 is connected to the right support 4b through the connecting seat 9, which is used to support the drilling machine 8.
[0026] The drilling machine 8 has a handle on one side, and the drill bit end of the drilling machine 8 passes through the connecting seat 9 and extends to one side of the connecting seat 9.
[0027] The specific working principle is as follows: the operator can drill holes in the steel pipe by holding the handle of the drilling machine 8. The drilling machine 8 rotates and moves up and down. The stroke is changed by the connecting rod 5 and the cylinder 6. The horizontal rotation is achieved by the bearing. During the process, the drilling machine 8 always remains horizontal. The drilling is fast and efficient and does not require frequent movement of the steel pipe.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
