[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] like Figure 1-11The new rotary hole-turning device shown includes a rotary seat 1, on which a drill bit 2 that can rotate relative to the rotary seat is inserted, and a pull-out needle 3 with one end extending and inserted into the drill bit 2 is provided on the rotary seat 1. When the rotary seat 1 rotates relative to the drill bit 2, the pull-out needle 3 slides relative to the rotary seat 1 to extend out of the drill bit 2 or retract into the drill bit 2. Specifically, the diameter of the rotary seat 1 gradually decreases from top to bottom and is in a conical shape. The rotary seat 1 is provided with a slide groove 4 opening on its outer wall. The slide groove 4 extends from bottom to top around the axis of the rotary seat 1 in a spiral shape, wherein the pitch of the spiral line where the slide groove 4 is located is 5-20mm, preferably 15mm, the spiral turn is 0.6-1.5, preferably 0.9, the angle between the side wall of the slide groove 4 and the axis of the rotary seat 1 is 30°~60°, preferably 45°, the number of the slide grooves 4 is two, the two slide grooves 4 are symmetrically arranged, the number of the rotary needles 3 is two, the two rotary needles 3 are symmetrically spaced, and the two rotary needles 3 are spaced apart, which can avoid mechanical wear caused by mutual friction when the rotary needles 3 slide out or retract into the drill bit 2, and can effectively improve the service life of the rotary needles 3. As can be seen from the figure, when the rotary seat 1 rotates relative to the drill bit 2, the rotary needle 3 slides relative to the rotary seat 1 along the slide groove 4. When the pull-out needle 3 slides upwards along the slide groove 4 relative to the rotary seat 1, the end of the pull-out needle 3 inserted in the drill bit 2 slides out of the drill bit 2. When the pull-out needle 3 slides downwards along the slide groove 4 relative to the rotary seat 1, the end of the pull-out needle 3 inserted in the drill bit 2 slides and retracts into the drill bit 2. When the present invention is used for pipeline processing, it is installed on a driving device. When drilling, the rotary seat 1 is rotated to make the end of the pull-out needle 3 inserted in the drill bit 2 retract into the drill bit 2. The drill bit 2 is driven by the driving device to rotate clockwise and move downward to drill an assembly hole. When the drill bit 2 is located in the assembly hole, the rotary seat 1 is rotated to make the end of the pull-out needle 3 inserted in the drill bit 2 extend out of the drill bit 2. The drill bit 2 and the pull-out needle 3 are driven by the driving device to rotate counterclockwise and move upward to complete the hole turning. In summary, the device realizes the punching and flanging of metal pipes at one workstation, simplifies the process, improves production efficiency, and has a simple overall structure and is easy to implement.

[0029] Further, the pull-out needle 3 includes a pull-out upper part 31 inserted on the drill bit 2, and a pull-out lower part 32 located in the slide groove 4 is provided on the pull-out upper part 31. When the rotary seat 1 rotates relative to the drill bit 2, the pull-out lower part 32 slides along the slide groove 4 so that the pull-out upper part 31 extends out of the drill bit 2 or retracts into the drill bit 2. Specifically, the pull-out upper part 31 and the pull-out lower part 32 are welded, and welding is conducive to improving the stability of the connection between the pull-out upper part 31 and the pull-out lower part 32, preventing loosening, and improving the service life.

[0030] Furthermore, the cross section of the screw-pull lower part 32 includes two oppositely arranged straight edges 321, and two oppositely arranged arc edges 322 are arranged between the two straight edges 321. The angle between the line L1 connecting the midpoints of the two straight edges 321 and the line L2 connecting the diagonals of the two arc edges 322 is 3° to 15°, preferably 7°, and the radius of the arc edge 322 is 4 to 13 mm, preferably 8 mm. The screw-pull lower part 32 adopts the above structure to be highly matched with the slide groove 4, effectively preventing the screw-pull lower part 32 from moving forward and backward in the radial direction of the drill bit 2 in the slide groove 4 when the drill bit 2 moves up to turn the hole, avoiding different diameters of the turned holes, and improving the accuracy of the turned holes.

[0031] Furthermore, the drill bit 2 is provided with a distance limiting mechanism 5 for limiting the length of the extraction needle 3 extending out of the drill bit 2 . The drill bit 2 is provided with a positioning piece 6 located at the lower side of the rotary seat 1 and rotating synchronously with the drill bit 2. The drill bit 2 is provided with an adjusting component 7 which can move along its axial direction and rotate synchronously with the rotary seat 1 relative to the drill bit 2. Specifically, the adjusting component 7 includes an adjusting base 71 sleeved on the drill bit 2 and an adjusting shell 72 detachably connected to the adjusting base 71. Specifically, the distance limiting mechanism 5 includes a first distance limiting groove 51 and a second distance limiting groove 52 arranged on the positioning piece 6, and a distance limiting column 53 arranged on the adjusting base 71 and selectively plugged with the first distance limiting groove 51 or the second distance limiting groove 52; when the distance limiting column 53 is plugged into the first distance limiting groove 51, the pull-out needle 3 is retracted into the drill bit 2, and when the distance limiting column 53 is plugged into the second distance limiting groove 52, the pull-out needle 3 extends out of the drill bit 2. This structure limits the moving distance of the extraction needle 3 on the slide groove 4 by reciprocating the distance limiting column 53 between the first distance limiting groove 51 and the second distance limiting groove 52 when the positioning member 6 rotates relative to the rotary seat 1. The structure is simple and the precision is high.

[0032] Furthermore, the drill bit 2 is provided with a positioning pin 8 extending along its radial direction, and the positioning member 6 is provided with a positioning hole 60 which is snap-fitted with the positioning pin 8. This structure realizes the synchronous rotation of the positioning member 6 and the drill bit 2 relative to the rotary seat 1. Specifically, the positioning pin 8 is inserted into the drill bit 2. Further, the drill bit 2 is sleeved with a first fastener 9 for fixing the positioning member 6. Specifically, the first fastener 9 is a retaining spring. The first fastener 9 realizes the fixing of the positioning member 6 on the drill bit 2.

[0033] Further, a block 100 is provided on the adjustment housing 72, and a slot 200 extending along the axial direction thereof and engaging with the block 100 is provided on the rotary seat 1, and this structure enables the adjustment component 7 and the rotary seat 1 to rotate relative to the drill bit 2. Further, a second fastener 300 for fixing the adjustment base 71 is sleeved on the drill bit 2, and specifically, the second fastener 300 is a retaining spring, and the second fastener 300 enables the adjustment component 7 to be fixed on the rotary seat 1. Further, an elastic member 400 is provided between the second fastener 300 and the adjustment base 71, and specifically, the elastic member 400 is a spring sheet, and the setting of the elastic member 400 enables the adjustment component 7 to move in the axial direction of the drill bit 2, and then enables the distance limiting column 53 to be selectively plugged and engaged with the first distance limiting groove 51 or the second distance limiting groove 52. The specific principle is as follows: the adjusting component 7 is pulled outward to compress the elastic member 400. At this time, the adjusting component 7 and the drill bit 2 can rotate synchronously relative to the rotary seat 1. When the distance limit column 53 arranged on the adjusting component 7 moves to the upper side of the first distance limit groove 51 or the second distance limit groove 52, the external force on the adjusting component 7 is canceled. At this time, the elastic member 400 stretches out to push the distance limit column 53 into the first distance limit groove 51 or the second distance limit groove 52, so that the distance limit column 53 is plugged into the first distance limit groove 51 or the second distance limit groove 52.
