Detailed implementation manners

[0026] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings.

[0027] As Figure 1 and Figure 2 shown, a steel pipe drilling and tapping device 10 includes a machine platform 100, a material rotating assembly 200 and a processing assembly 300. A loading seat 400 for supporting the steel pipe is arranged on the machine platform 100. The material rotating assembly 200 includes a pushing head 210, a material rotating driving part 220 and a material rotating head 230. The pushing head 210 is rotatably arranged at one end of the machine platform 100. The material rotating driving part 220 is arranged at the end of the machine platform 100 away from the pushing head 210. The material rotating head 230 is arranged on the output shaft of the material rotating driving part 220, and the material rotating head 230 is aligned with the pushing head 210. When the material rotating driving part 220 drives the material rotating head 230 to approach the pushing head 210, the material rotating head 230 and the pushing head 210 jointly clamp the two ends of the steel pipe. When the material rotating driving part 220 drives the material rotating head 230 to rotate, the steel pipe rotates. The processing assembly 300 includes a sliding driving part 310, a sliding plate 320, a drilling mechanism 330 and a tapping mechanism 340. The sliding driving part 310 is arranged on the machine platform 100. The sliding plate 320 is slidably arranged on the machine platform 100, and the sliding plate 320 is connected to the output shaft of the sliding driving part 310. The drilling mechanism 330 and the tapping mechanism 340 are arranged on the sliding plate 320 at intervals. When the sliding driving part 310 drives the sliding plate 320 to slide, the drilling mechanism 330 and the tapping mechanism 340 reciprocate along the length direction of the steel pipe. The drilling mechanism 330 is used for drilling the steel pipe, and the tapping mechanism 340 is used for tapping the hole position of the steel pipe.

[0028] It should be noted that the material loading seat 400 is installed on the machine table 100, and the material loading seat 400 is used to support the steel pipe. The material ejecting head 210 is rotatably installed on the machine table 100. For example, the material ejecting head 210 is installed on the machine table 100 through a bearing, so that it can rotate relative to the machine table 100. The material rotating driving part 220 is fixedly installed on the machine table 100, and the material rotating driving part 220 and the material ejecting head 210 are respectively located at two ends of the steel pipe in the length direction. The material rotating head 230 is installed on the output shaft of the material rotating driving part 220, and the material rotating driving part 220 drives the material rotating head 230 to approach or move away from the material ejecting head 210. When the material rotating head 230 approaches the material ejecting head 210, the material rotating head 230 and the material ejecting head 210 can respectively push against two ends of the steel pipe, so that the steel pipe is clamped and fixed by the material rotating head 230 and the material ejecting head 210 together. In this way, when the material rotating driving part 220 drives the material rotating head 230 to rotate, the steel pipe can be rotated. Further, the sliding driving part 310 is installed on the machine table 100, the drilling mechanism 330 and the tapping mechanism 340 are both installed on the sliding plate 320, and there is a gap between the drilling mechanism 330 and the tapping mechanism 340. In one embodiment, the sliding driving part 310 is a lead screw module driven by a motor. In this way, the sliding plate 320 drives the drilling mechanism 330 and the tapping mechanism 340 to slide along the length direction of the steel pipe, so that the drilling mechanism 330 can drill the steel pipe, and the tapping mechanism 340 can perform industrial operations on the steel pipe. It should be noted that both the drilling mechanism 330 and the tapping mechanism 340 are prior arts and will not be elaborated here. In this way, the rotation of the steel pipe is adjusted, and then the sliding driving part 310 drives the drilling mechanism 330 and the tapping mechanism 340 to drill and tap the steel pipe in sequence. Compared with the manual operation in the prior art, on the one hand, the drilling and tapping are more stable, avoiding wrong drilling and missing drilling, and improving the production quality. On the other hand, the processing efficiency can be improved.

[0029] As Figure 1 shown, in one embodiment, the material loading seat 400 includes two material loading cylinders 410 and two material loading blocks 420. The two material loading cylinders 410 are arranged at intervals on the machine table 100, and the two material loading blocks 420 are respectively arranged on the output shafts of the two material loading cylinders 410. When the material loading cylinder 410 drives the material loading block 420 to rise, the material loading block 420 drives the steel pipe to rise to align with the material ejecting head 210.

[0030] It should be noted that when the material-rotating driving member 220 drives the material-rotating head 230 to rotate so as to rotate the steel pipe, in order to prevent the material-carrying seat 400 from obstructing the steel pipe, the material-carrying seat 400 is arranged in the above structure. Specifically, the material-carrying cylinder 410 drives the material-carrying block 420 to rise, so that the steel pipe supported by the material-carrying block 420 is aligned with the material-pushing head 210 and the material-rotating head 230. Then, the material-rotating driving member 220 drives the material-rotating head 230 to abut against the end of the steel pipe, and then the material-carrying cylinder 410 drives the material-carrying block 420 to descend to move away from the steel pipe.

[0031] As Figure 1 shown, in one embodiment, the steel pipe drilling and tapping device 10 further includes a material-pressing cylinder 510 and a material-pressing block 520. The material-pressing cylinder 510 is arranged on the sliding plate 320, the material-pressing block 520 is arranged on the output shaft of the material-pressing cylinder 510, and the material-pressing block 520 is located above the material-carrying seat 400. When the material-pressing cylinder 510 drives the material-pressing block 520 to descend, the material-pressing block 520 presses the steel pipe tightly.

[0032] It should be noted that in order to ensure that the material-rotating driving member 220 can drive the material-rotating head 230 to accurately push and position the end of the steel pipe, when the material-carrying cylinder 410 drives the material-carrying block 420 to rise so that the steel pipe is aligned with the material-pushing head 210 and the material-rotating head 230, the material-pressing cylinder 510 drives the material-pressing block 520 to descend to press and fix the steel pipe tightly.

[0033] As Figure 1 and Figure 2 shown, in one embodiment, the steel pipe drilling and tapping device 10 further includes a switching assembly 600. The switching assembly 600 includes a switching cylinder 610 and a switching plate 620. The switching cylinder 610 is arranged on the machine table 100, the switching plate 620 is slidably arranged on the machine table 100, and the switching plate 620 is connected to the output shaft of the switching cylinder 610. The material-rotating driving member 220 is arranged on the switching plate 620.

[0034] It should be noted that the switching cylinder 610 is installed on the machine table 100, the switching plate 620 is installed on the machine table 100 through a slide rail, and the material-rotating driving member 220 is installed on the switching plate 620. When the switching cylinder 610 drives the switching plate 620 to slide, the material-rotating driving member 220 can slide along the radial direction of the steel pipe to approach or move away from the steel pipe.

[0035] As Figure 1 and Figure 2 shown, in one embodiment, the switching assembly 600 further includes a notch driving member 630 and a cutter 640. The notch driving member 630 is arranged on the switching plate 620, and the notch driving member 630 and the material-rotating driving member 220 are distributed adjacent to each other. The cutter 640 is arranged on the output shaft of the notch driving member 630. The switching plate 620 is used to drive one of the cutter 640 and the material-rotating head 230 to be aligned with the material-pushing head 210.

[0036] It should be noted that the incision driving member 630 and the material rotating driving member 220 are both provided on the switching plate 620, and there is a gap between the incision driving member 630 and the material rotating driving member 220. Among them, the cutting knife 640 is installed on the output shaft of the incision driving member 630. In this way, the switching plate 620 can drive one of the cutting knife 640 and the material rotating head 230 to approach the end of the steel pipe.

[0037] As Figure 2 and Figure 3 shown, in one embodiment, the incision driving member 630 includes a cutting cylinder 631, a first slider 632 and a cutting motor 633. The cutting cylinder 631 is disposed on the switching plate 620. The first slider 632 is slidably disposed on the switching plate 620, and the first slider 632 is connected to the output shaft of the cutting cylinder 631. The cutting motor 633 is disposed on the first slider 632. The cutting knife 640 is disposed on the output shaft of the cutting motor 633. When the cutting cylinder 631 is used to drive the first slider 632 to approach the steel pipe, the cutting knife 640 can create a positioning groove 21 at the end of the steel pipe 20.

[0038] It should be noted that the first slider 632 is installed on the switching plate 620 through a slide rail. The cutting cylinder 631 drives the first slider 632 to slide. The cutting motor 633 is installed on the first slider 632. In this way, the cutting cylinder 631 drives the cutting motor 633 to approach or move away from the end of the steel pipe, so that the cutting knife 640 can form a positioning groove 21 during the processing of the steel pipe.

[0039] As Figure 2 shown, in one embodiment, the material rotating driving member 220 includes a material rotating cylinder 221, a second slider 222 and a material rotating motor 223. The material rotating cylinder 221 is disposed on the switching plate 620. The second slider 222 is slidably disposed on the switching plate 620, and the second slider 222 is connected to the output shaft of the material rotating cylinder 221. The material rotating motor 223 is disposed on the second slider 222. The material rotating head 230 is disposed on the output shaft of the material rotating motor 223. When the material rotating cylinder 221 is used to drive the second slider 222 to approach the steel pipe, the material rotating head 230 can be inserted into the positioning groove 21 of the steel pipe 20.

[0040] It should be noted that the second slider 222 is slidably mounted on the switching plate 620 through a slide rail, and the material rotating cylinder 221 drives the material rotating motor 223 to approach or move away from the steel pipe along the length direction of the steel pipe. The material rotating head 230 is mounted on the output shaft of the material rotating motor 223. When the material rotating motor 223 approaches the steel pipe, the material rotating head 230 abuts against and clamps the steel pipe. Specifically, a part of the structure of the material rotating head 230 is inserted into the positioning groove 21 of the steel pipe. Thereby enabling the material rotating head 230 to stably drive the steel pipe to rotate synchronously. In one embodiment, in order to improve the stability of the material rotating head 230, the material rotating head 230 is also rotatably mounted on the second slider 222 through a bearing.

[0041] As Figure 2 shown, in one embodiment, insertion pieces 231 are provided on one side surface of the material rotating head 230 close to the steel pipe, and the insertion pieces 231 are used for being inserted into the positioning groove 21. In this way, when the material rotating head 230 rotates, the insertion pieces 231 can reliably drive the steel pipe to rotate synchronously.

[0042] As Figure 2 shown, in one embodiment, a conical body 232 is further provided on one side surface of the material rotating head 230 close to the steel pipe, the insertion pieces 231 are located on the conical body 232, and the conical body 232 is used for being inserted into the end of the steel pipe.

[0043] It should be noted that the conical body 232 is used for being inserted into the pipe orifice end of the steel pipe. Under the cooperation of the conical body 232 and the insertion pieces 231, the material rotating head 230 can reliably push and fix the steel pipe.

[0044] In one embodiment, the drilling mechanism 330 and the tapping mechanism 340 can use existing devices. In another embodiment, the drilling mechanism 330 includes a drill base, a lifting motor, a lifting pipe, a drilling motor and a drill bit. The drill base is arranged on the sliding plate 320, the lifting motor is arranged on the drill base, the lifting pipe is slidably arranged on the drill base along the vertical direction, and the upper end of the lifting pipe is connected to the output shaft of the lifting motor. The drilling motor is arranged at the bottom of the lifting pipe, and the drill bit is arranged on the output shaft of the drilling motor. In this way, the lifting motor drives the lifting pipe to perform lifting motion, and the drilling motor drives the drill bit to continuously rotate, so that the drill bit can drill holes in the steel pipe. Further, the structure of the tapping mechanism 340 is similar to the structure of the drilling mechanism 330. The difference between the two lies in that the drilling mechanism 330 uses a drill bit, and the tapping mechanism 340 uses a tapping head.

[0045] Thus, for the above-mentioned steel pipe drilling and tapping device 10, after placing the steel pipe on the material loading seat 400, the pressing block 520 is driven by the pressing cylinder 510 to press the steel pipe tightly. The cutting cylinder 631 drives the cutter 640 to form a positioning groove 21 at the end of the steel pipe 20. Then, the switching cylinder 610 drives the switching plate 620 to slide, so that the cutter 640 moves away from the steel pipe and the material rotating head 230 approaches the steel pipe. Then, the material rotating cylinder 221 drives the material rotating head 230 to approach the steel pipe, so that the material rotating head 230 and the material ejecting head 210 jointly clamp and fix the steel pipe. Thus, as the steel pipe rotates, the sliding driving member 310 drives the sliding plate 320 to slide, so that the drilling mechanism 330 and the tapping mechanism 340 drill and tap the steel pipe respectively. Thus, automatic drilling and tapping of the steel pipe are realized, mis-drilling and missed drilling are avoided, the production quality is improved, and the processing efficiency can be improved.

[0046] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
