Description

Technical Field

[0001] The invention relates to the technical field of pipe processing, and in particular to an intelligent processing robot for metal pipes. Background Art

[0002] Metal pipe fittings are metal parts made of various metals according to the purpose and needs of the final product, and are widely used in industrial engineering and daily life. For example, in industrial engineering and daily life, they are used to transport liquids. Due to the humidity in the air, the inner wall of the metal pipe fittings will be corroded and rusted in long-term use, causing metal impurities in the transported liquid, which will seriously affect the operation of the machine. Therefore, it is necessary to grind the inner wall of the metal pipe fittings. The existing intelligent processing robots for metal pipe fittings generally clamp and fix one end of the pipe fitting, and set a retractable grinding and cleaning device at the other end to grind the inner wall of the metal pipe fittings.

[0003] The existing intelligent processing robots for metal pipes have the following problems:

[0004] 1. When processing the inner wall of a metal pipe, one end of the metal pipe is usually fixed, and the inner wall is polished by inserting a polishing device into the metal pipe, and the polishing device is moved while polishing. However, the efficiency of polishing the inner wall by inserting a polishing device into the metal pipe is low. Therefore, currently, multiple polishing devices are threadedly connected to increase the polishing range, thereby increasing the polishing efficiency of the polishing device. However, when multiple polishing devices are spliced ​​by threaded connection, if the rotation direction of the polishing device is the same as the threaded connection direction between the multiple polishing devices, adjacent polishing devices are prone to loosening after long-term polishing; otherwise, adjacent polishing devices are difficult to disassemble later or thread slippage occurs, making them impossible to connect.

[0005] 2. When processing the inner wall of a metal pipe, when it is necessary to process pipes with different outer diameters, since the existing grinding device can generally only grind pipes with the same outer diameter, it is necessary to replace different grinding devices, which leads to a decrease in grinding efficiency.

[0006] 3. When processing the inner wall of a metal pipe fitting, a grinding device generally uses a grinding block to grind the inner wall of the pipe fitting. When the grinding block is worn, the grinding block needs to be replaced, resulting in a waste of the grinding block. Summary of the invention

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a metal pipe intelligent processing robot comprises a horizontal base plate 1, a vertical support plate 2 is fixedly installed on the right side of the upper surface of the base plate 1, a rotating mechanism 3 is installed on the support plate 2, the rotating mechanism 3 comprises a first rotating rod 301, a first positioning hole 302, a first mounting plate 303, a first limiting ring 304, a first limiting rod 305, and a rotating motor 306, the first rotating rod 301 is rotatably installed on the left side of the support plate 2, and the left end surface of the first rotating rod 301 is provided with uniformly distributed first positioning holes 302, the first mounting plate 303 is uniformly installed on the first rotating rod 301 and is located outside the first positioning hole 32, the first mounting plate 303 corresponds to the number of the first positioning holes 302, the first limiting ring 304 is fixedly installed on the first mounting plate 303, the first limiting rod 305 is slidably installed in the first limiting ring 304 and radially penetrates the first positioning hole 302, and a rotating motor 306 is installed on the right side of the support plate 2 through a motor frame, and the output end of the rotating motor 306 is connected to the first rotating rod 301.

If multiple rotating bases 4 are spliced ​​by threaded connection, during the operation, if the rotation direction of the rotating base 4 is the same as the threaded connection direction between the multiple rotating bases 4, it is easy to cause looseness between adjacent rotating bases 4 after long-term grinding; otherwise, it makes it difficult to disassemble the adjacent rotating bases 4 later or cause thread slippage, making it impossible to connect. The use of plug-in method can avoid this situation.

[0037] like Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a grinding and cleaning mechanism 5 is installed on the rotating base 4, and the grinding and cleaning mechanism 5 includes a grinding sliding block 501, a third mounting plate 502, a second rotating rod 503, a ratchet 504, a positioning pin 505, a pawl 506, a third rotating rod 507, a rotating roller 508, a mounting groove 509, a connecting rod 510, a pressing block 511, a limiting gear 512, a mounting frame 513, a sleeve 514, a limiting spring 515, a slider 516, a limiting strip 517, a U-shaped mounting frame 518, and a cleaning sliding block 519.

A third rotating rod 507 is installed between the ratchet 506 and the third mounting plate 502 and on the other side of the grinding sliding block 501. A rotating roller 508 is installed on the third rotating rod 507. The rotating roller 508 and the second rotating rod 503 are both provided with mounting grooves 509. A connecting rod 510 is installed in the mounting groove 509. A pressing block 511 is rotatably installed on the connecting rod 510.

[0038] The two ends of the sandpaper in the length direction are pressed respectively under the pressing blocks 511 located on both sides of the grinding sliding block 501. One end of the sandpaper is rotated by the ratchet 504 to drive the sandpaper to be wound around the second rotating rod 503. The ratchet 506 can be used to control the retraction and release of the grinding sandpaper. The other end of the sandpaper is wound around the rotating roller 508. The limit gear 512 is limited by the limit bar 517 to control the retraction and release of the grinding sandpaper. When the sandpaper needs to be replaced, the position of the ratchet 506 and the limit bar 517 is adjusted to rotate the ratchet 504 and the limit gear 512 to achieve tightening and adjustment, thereby moving the grinding surface of the sandpaper.

[0040] When fixing the pipe fitting, one end of the pipe fitting is placed between the two V-shaped plates 606, and the bidirectional screw rod 603 is rotated to drive the second sliding plate 605 to move so that the outer wall of the steel pipe is clamped by the two V-shaped plates 606; the outer wall of the pipe fitting can be effectively fixed by the set clamping mechanism 6, so as not to affect the grinding of the inner wall of the pipe fitting, and the use of the V-shaped plate 606 to clamp and fix the pipe fitting can effectively ensure the fixing effect of the pipe fitting and prevent the inner wall of the pipe fitting from relative rotation during grinding.
