[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 4As shown, the utility model discloses a drilling tool suitable for steel pipes, which is composed of a base plate 1, a tool seat 2, a baffle plate 3, a steel pipe 4 extending frontward and rearward in the length direction, a support plug block 5 and a limiting bolt 6. The baffle plate 3 and the tool seat 2 are both located above the base plate 1, and the limiting bolt 6 is inserted into one end of the tool seat 2 and threadedly matched with it. The tool seat 2 includes a mounting hole 21 for inserting the steel pipe 4, and the supporting plug block 5 is located at the bottom of the mounting hole 21 and is slidably installed on the tool seat 2. After the steel pipe 4 to be drilled is inserted between the baffle plate 3 and the tool seat 2, at this time, since the limiting bolt 6 is inserted into the tool seat 2 and threadedly matched with it, the limiting bolt 6 is rotated to make one side end face of it abut against the steel pipe 4. At this time, there is no When the limit bolt 6 is rotated counterclockwise, the steel pipe 4 inserted in the mounting hole 21 cannot rotate in the tooling seat 2, thereby preventing the occurrence of misalignment of the drilling position due to the rotation of the steel pipe 4. In addition, the support block 5 is located below the steel pipe 4 and can support the steel pipe 4. Because the support block 5 is slidably installed on the tooling seat 2, it can be adjusted in height according to steel pipes 4 of different diameters and is always located at the bottom of the steel pipe 4. It also includes a driving member 7. The baffle 3 includes a front limit portion 31 and a rear limit portion 32 for inserting on the front and rear sides of the steel pipe 4. The front limit portion 31 and the rear limit portion 32 are both made of rubber and other materials that are easy to deform. The front limit portion 31 and the rear limit portion 32 are both slidably installed along the front and rear directions. The front limiting part 31 and the rear limiting part 32 are inserted into the bottom plate 1, and are used to drive the front limiting part 31 and the rear limiting part 32 to move closer to or away from each other. 1. Since the driving part 7 can drive the front limiting part 31 and the rear limiting part 32 to move closer to or away from each other, it can adapt to the steel pipes 4 of different lengths loaded on the tooling seat 2 to achieve the front limiting part 31 and the front side of the steel pipe 4 abutting against each other, and the rear limiting part 32 and the rear side of the steel pipe 4 abutting against each other, so that when the limiting bolt 6 can prevent the steel pipe 4 from rotating in the circumferential direction, the front limiting part 31 and the rear limiting part 32 can limit the axial direction of the steel pipe 4, reduce the offset position, and ensure the accuracy and consistency of the drilling; 2. The introduction of the driving part 7 enables the front limiting part 31 and the rear limiting part 32 to be Dynamically approaching or moving away as needed not only facilitates the processing of steel pipes 4 of different lengths, but also is more flexible when the hole spacing needs to be adjusted, greatly improving the adaptability and processing efficiency of the equipment; 3. Since the front limit portion 31 and the rear limit portion 32 are both made of materials that are easily deformed, after the front limit portion 31 and the rear limit portion 32 are away from the tooling seat 2, the front limit portion 31 and the rear limit portion 32 will be easily contacted during the process of inserting the steel pipe 4 into the mounting hole 21. Therefore, the front limit portion 31 and the rear limit portion 32 made of materials that are easily deformed allow the steel pipe 4 to pass through more smoothly and realize the insertion of the mounting hole 21, and then adjust the front limit portion 31 and the rear limit portion 32 to realize the limitation of the front and rear sides of the steel pipe 4.

[0029] Among them, the driving member 7 is a bidirectional screw, the driving member 7 is rotatably installed on the tooling seat 2, and includes a front threaded section 71 and a rear threaded section 72, the bottom of the front limiting portion 31 is threadedly matched with the front threaded section 71, and the bottom of the rear threaded section 72 is threadedly matched with the bottom of the rear limiting portion 32. Since the driving member 7 is rotatably installed on the tooling seat 2 and includes a front threaded section 71 threadedly matched with the front limiting portion 31 and a rear threaded section 72 threadedly matched with the rear limiting portion 32, the front limiting portion 31 and the rear limiting portion 32 on both sides of the driving member 7 can be moved away from or close to each other by rotating the driving member 7. Moving away from each other can facilitate the installation or removal of the steel pipe 4 into or out of the tooling seat 2, while moving close to each other can achieve axial limitation of the steel pipe 4 inserted into the tooling seat 2.

[0030] It also includes a contact plate 8 located on the front side of the driving member 7, the rear side of the contact plate 8 is in contact with the base plate 1, and a plurality of contact grooves 81 are arranged at intervals in the circumferential direction of the contact plate 8. 1. Since the rear side of the contact plate 8 is in contact with the base plate 1, when the driving member 7 needs to be rotated, the contact plate 8 cannot move backward, so that force can be applied to the contact plate 8 to drive the driving member 7 to rotate; 2. Since a plurality of contact grooves 81 are arranged in the circumferential direction of the contact plate 8, the friction force of the contact plate 8 is increased, which facilitates the rotation of the contact plate 8 to drive the driving member 7.

[0031] The limit plate 22 is detachably mounted on the tooling seat 2 by means of bolts, snaps, etc., and a plurality of adapting holes 221 of different sizes are arranged on the limit plate 22. The upward projection of the mounting hole 21 falls on the limit plate 22. 1. Since the adapting holes 221 on the limit plate 22 are of different sizes, the drilling of the steel pipe 4 is achieved by injecting a drill bit of the required aperture into the adapting hole 221 of adapted size and then dropping it into the steel pipe 4; 2. Since the limit plate 22 and the tooling seat 2 are detachable, if the drill bit shakes during the drilling process and causes damage to the limit plate 22, the limit plate 22 can be removed and replaced.

[0032] In addition, the limit plate 22 includes an installation section 222, and the tooling seat 2 is provided with a installation groove 23 corresponding to the installation section 222. The tooling seat 2 is protrudingly provided with a plurality of limit plugs 24 located in the installation groove 23, and the installation section 222 is provided with a limit slot 2221 corresponding to each limit plug 24. Since the installation section 222 of the limit plate 22 is provided with a limit slot 2221 corresponding to each limit plug 24, the limit plate 22 can be replaced by moving the limit plate 22 upward. When the limit plate 22 is located on the tooling seat 2, the limit plate 22 will not move during the operation of the drill bit due to the presence of each limit plug 24.

[0033] Preferably, each of the limit blocks 24 is arranged in a stepped shape with a narrow top and a wide bottom. Since each limit block 24 is narrow at the top and a wide bottom, when the limit plate 22 is installed on the tooling seat 2, the first thing that falls into each limit slot 2221 is the uppermost side of each limit block 24, that is, the narrowest part. Therefore, each limit block 24 arranged with a narrow top and a wide bottom allows each limit block 24 to fall into the corresponding limit slot 2221 more smoothly, thereby realizing the installation of the limit plate 22 on the tooling seat 2.

[0034] In addition, it also includes a number of mounting bolts (not shown in the figure), the support plug 5 includes a fixing plate 51, the fixing plate 51 is provided with a through hole 511, and the tooling seat 2 is provided with a number of screw holes 25 arranged at intervals along the up and down directions corresponding to each through hole 511. Since the fixing plate 51 is provided with a through hole 511, and the tooling seat 2 is provided with a number of screw holes 25 corresponding to each through hole 511, the mounting bolts are passed through the through holes 511 and then matched with the screw holes 25 at different heights, so that the position of the support plug 5 at different heights on the tooling seat 2 can be determined, so that the upper end face can be abutted against the bottom of the steel pipe 4.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
