Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe fitting processing application, in particular to a processing equipment for adapting to pipe fittings of multiple specifications and a control method thereof. BACKGROUND

[0002] In the pipe fitting processing industry, it is often necessary to cut and polish pipe fittings of different specifications (such as different diameters and lengths).

[0003] At present, traditional processing equipment is usually designed for a single specification of pipe fittings. When pipe fittings of different diameters and lengths need to be processed, the clamps need to be disassembled and replaced, and the equipment parameters need to be adjusted, which is tedious and time-consuming, resulting in a significant reduction in production efficiency, especially in small-batch, multi-specification flexible production scenarios.

[0004] When cutting pipe fittings, the pipe fitting is prone to axial misalignment of the centerline and the processing mechanism (such as the cutting head and the positioning ring) due to the offset of the conveying path, which requires manual adjustment repeatedly, not only time-consuming, but also difficult to ensure positioning accuracy, thereby affecting the subsequent processing quality. If the positioning mechanism cannot achieve precise coaxial positioning, problems such as cutting deviation and port inclination are likely to occur. At the same time, if the pipe fitting has radial shaking during cutting, it will further affect the flatness of the cutting surface, and additional manpower is needed to correct it, increasing production costs.

[0005] Moreover, most of the equipment only has a single function (such as only cutting or only polishing), and the pipe fitting needs to be manually transferred to another polishing equipment for port processing after cutting, which not only increases the labor intensity, but also may cause damage to the pipe fitting due to collision during the transfer process, and the delay in the connection between processes further reduces the overall production efficiency.

[0035] As shown in Figures 1-11 A control method of a processing equipment suitable for multiple specifications of pipe fittings, comprising the following steps: S1, first, place the pipe to be processed on the slope of the feeding frame 71. The pipe slides down along the slope. The auxiliary rollers 76 on the slope reduce friction through rolling and guide the pipe to move stably to the driving rollers 771; S2, then, through the cooperation of the lifting rod 72 and the positioning cylinder 73 of the feeding mechanism 7, drive the feeding frame 71 to rise and fall by the feeding cylinder 75, adjust the axial line of the pipe on the feeding frame 71 to be coaxial with the fixed ring 636 of the adjusting and positioning mechanism 6; S3, then, start the feeding motor 776. The output shaft drives the driving wheel B775 to rotate. The rotation is transmitted to the driven wheel B773 through the toothed belt B774, and then one of the driving rollers 771 is rotated. The other driving roller 771 is synchronously rotated through the meshing connection of the bevel gears 772. The two driving rollers 771 jointly clamp the pipe and convey it in the coaxial direction; S4, when the pipe is conveyed to the position detected by the two laser positioning sensors 392, the feeding mechanism 7 stops. At this time, the stabilizing cylinder 52 in the stabilizing assembly 5 is started. The driving rod of the stabilizing cylinder 52 is extended to push the arc-shaped stabilizing block 53 to move towards the pipe. Since the stabilizing block 53 is coaxial with the adjusting and positioning mechanism 6, and the inner wall of the stabilizing block 53 is fitted with equally spaced balls 54, the balls 54 on the inner wall of the stabilizing block 53 will finally fit the outer wall of the pipe. Through the arc-shaped structure, the pipe is stably surrounded. Through the balls 54, the friction between the pipe and the stabilizing block 53 is reduced, so that the pipe does not shake radially during cutting; S5、then start the two adjustment components 63 of the moving motor 633, the output shaft of the moving motor 633 drives the gear 634 to rotate, because the gear 634 is engaged with the rack 61 on the base 1, and the moving plate 631 is slidingly connected with the guide rail 62 through the sliding seat 632, the rotation of the gear 634 drives the moving plate 631 to translate along the guide rail 62, so that the two adjustment components 63 translate to the port position of the pipe outer wall; S6、then after the sleeve into the pipe, start the multiple clamping cylinders 637 distributed on the outer wall of the fixing ring 636, the driving rod of the clamping cylinder 637 extends, pushes the arc-shaped clamping block 638 to close to the outer wall of the pipe, until the multiple arc-shaped clamping blocks 638 clamp the pipe together, realize the radial positioning and fixing of the pipe, adapt to multiple specifications of pipes with different diameters, then the two adjustment components 63 carry the pipe to translate on the guide rail 62 to the position of the required pipe size distance input by the external control system, and one of the two adjustment components 63 returns to the position of a fixed ring 636 width away from the laser cutting head 391; S7、then start the laser positioning sensor 392 of the laser cutting mechanism 3, because the laser positioning sensor 392 and the laser cutting head 391 are arranged in three-point one-line, the laser positioning sensor 392 first positions the preset cutting position of the pipe, feeds back the position signal to the control system, the control system starts the adjusting motor 32, the output shaft of the adjusting motor 32 drives the driving wheel A33 to rotate, drives the driven wheel A35 through the toothed belt A34, and then drives the lead screw 36 to rotate, because the lead screw 36 is threadedly connected with the threaded sleeve 37, and the sliding plate 38 is slidingly connected with the mounting frame 31 through the sliding rail A311, the rotation of the lead screw 36 drives the threaded sleeve 37 to drive the sliding plate 38 to translate along the sliding rail A311, so that the laser cutting head 391 moves to the position directly above the cutting position, the lifting cylinder 39 is started, the driving rod of the lifting cylinder 39 drives the laser cutting head 391 to descend to the appropriate cutting height, then the laser cutting head 391 emits laser to accurately cut the pipe, after cutting, the lifting cylinder 39 drives the laser cutting head 391 to reset; S8、then after the pipe is cut, the two adjustment components 63 simultaneously drive the cut pipe to translate a certain distance, then start the adjusting cylinder 45 of the polishing mechanism 4, the driving rod of the adjusting cylinder 45 pushes the sliding block 44 to move along the sliding rail B46 of the inner side wall of the rack 2, and then drives the connecting frame 43 and the double-shaft polishing motor 41 to move downward, so that the axis of the double-shaft polishing motor 41 is aligned with the axis of the fixing ring 636, the double-shaft polishing motor 41 is started, the output shaft of the double-shaft polishing motor 41 drives the two polishing ring sleeves 42 to rotate synchronously, at this time, the two pipes are inserted into the polishing ring sleeves 42 through the driving of the feeding assembly 77 and the driving of the two adjustment components 63, the inner and outer walls of the ports are polished, and the positions of the pipes are reset after polishing, so that the to-be-processed pipe port is located at the position of the laser positioning sensor 392; S9, after the polishing is ended, each mechanism is closed in turn: the clamping cylinder 637 drives the arc-shaped clamping block 638 to reset, the stabilizing cylinder 52 drives the stabilizing block 53 to reset, the operator or the matched unloading device takes out the pipe fitting processed from the adjusting and positioning mechanism 6; then the feeding mechanism 7, the laser cutting mechanism 3 and the polishing mechanism 4 are all reset to the initial position, and the next processing cycle of the multi-specification pipe fitting is prepared.

The inner wall of the feeding rack (71) is a symmetrical inclined surface, and multiple auxiliary rollers (76) are provided on the inclined surface. The feeding rack (71) is fixedly connected to the end face of the feeding assembly (77). The feeding assembly (77) includes a drive roller (771) rotatably connected to the feeding rack (71), and the two drive rollers (771) are connected by a bevel gear (772) at their opposite ends. The outer wall of the feeding rack (71) is bolted to the feeding motor (776). The output shaft end face of the feeding motor (776) is fixedly connected to the drive wheel B (775). The drive wheel B (775) is connected to the driven wheel B (773) through a toothed belt B (774). The driven wheel B (773) is sleeved on the end face of one of the drive rollers (771).

10. A control method for a processing equipment adapted to multi-specification pipe fittings according to any one of claims 1-9, characterized in that: Includes the following steps: S1. First, place the pipe to be processed on the inclined surface of the loading rack (71). The pipe slides down the inclined surface. During the process, the auxiliary roller (76) on the inclined surface reduces friction by rolling and guides the pipe to move smoothly to the drive roller (771). S2. Then, by cooperating with the lifting rod (72) of the feeding mechanism (7) and the positioning cylinder (73), the feeding cylinder (75) drives the feeding rack (71) to rise and fall, and adjusts the axis of the pipe on the feeding rack (71) to be coaxial with the fixing ring (636) of the adjusting positioning mechanism (6). S3. Next, start the feeding motor (776), whose output shaft drives the drive wheel B (775) to rotate, and transmits the drive wheel B (773) through the toothed belt B (774), which in turn drives one of the drive rollers (771) to rotate; the drive roller (771) drives the other drive roller (771) to rotate synchronously through the meshing bevel gear (772), and the two drive rollers (771) together clamp the pipe and transport it along the coaxial direction; S4. When the pipe fitting is transported to the position detected by the two laser positioning sensors (392) at the port, the feeding mechanism (7) stops. At this time, the stabilizing cylinder (52) in the stabilizing component (5) is activated. The stabilizing cylinder (52) drive rod extends and pushes the arc-shaped stabilizing block (53) to move towards the pipe fitting. Since the stabilizing block (53) is coaxial with the adjusting positioning mechanism (6) and the inner wall of the stabilizing block (53) is fitted with equidistantly arranged balls (54), the balls (54) on the inner wall of the stabilizing block (53) will eventually adhere to the outer wall of the pipe fitting. This not only forms a ring-shaped stabilization for the pipe fitting through the arc structure, but also reduces the friction between the pipe fitting and the stabilizing block (53) through the balls (54), ensuring that the pipe fitting does not sway radially during cutting. S5. Next, start the moving motor (633) of the two adjustment components (63). The output shaft of the moving motor (633) drives the gear (634) to rotate. Since the gear (634) meshes with the rack (61) on the base (1) and the moving plate (631) is slidably connected to the guide rail (62) through the slide (632), the rotation of the gear (634) will drive the moving plate (631) to translate along the guide rail (62), so that the two adjustment components (63) are translated to the position of the outer wall port of the pipe. S6. After the fitting is inserted, the multiple clamping cylinders (637) distributed around the outer wall of the fixing ring (636) are activated. The clamping cylinder (637) drive rod extends and pushes the arc-shaped clamping block (638) closer to the outer wall of the fitting until the multiple arc-shaped clamping blocks (638) clamp the fitting together, realizing the radial positioning and fixing of the fitting, adapting to multiple specifications of fittings with different diameters. Then, the two adjusting components (63) carry the fitting on the guide rail (62) and move it to the position of the required fitting size distance input by the external control system. One of the adjusting components (63) returns to the position one fixing ring (636) width away from the laser cutting head (391). S7. Next, the laser positioning sensor (392) of the laser cutting mechanism (3) is activated. Since the laser positioning sensor (392) and the laser cutting head (391) are set in a three-point line, the laser positioning sensor (392) first positions the preset cutting position of the pipe fitting and feeds the position signal back to the control system. The control system starts the regulating motor (32). The output shaft of the regulating motor (32) drives the driving wheel A (33) to rotate, and transmits the rotation to the driven wheel A (35) through the toothed belt A (34), which in turn drives the lead screw (36) to rotate. Since the lead screw (36) and the threaded sleeve (37) are connected, the laser positioning sensor (392) is activated. The screw thread is connected and the slide plate (38) is slidably connected to the mounting bracket (31) via the slide rail A (311). The rotation of the screw (36) will drive the threaded sleeve (37) to move the slide plate (38) along the slide rail A (311) so that the laser cutting head (391) moves to the position directly above the cut position. The lifting cylinder (39) is activated and its drive rod drives the laser cutting head (391) to descend to the appropriate cutting height. Then the laser cutting head (391) emits a laser to precisely cut the pipe. After the cutting is completed, the lifting cylinder (39) drives the laser cutting head (391) to reset. S8. After the pipe is cut, the two adjustment components (63) simultaneously drive the cut pipe to move a certain distance. Then, the adjustment cylinder (45) of the grinding mechanism (4) is started. The adjustment cylinder (45) drives the slider (44) to move along the slide rail B (46) on the inner side wall of the frame (2), thereby driving the connecting frame (43) and the dual-axis grinding motor (41) to move down, so that the axis of the dual-axis grinding motor (41) is aligned with the axis of the fixed ring (636). The dual-axis grinding motor (41) is started, and its output shaft drives the two grinding rings (42) to rotate synchronously. At this time, the pipes at both ends are driven by the feeding component (77) and the two adjustment components (63) to insert the relative ports of the two pipes into the inside of the grinding rings (42), so as to grind the inner and outer walls of the ports. After grinding, the position of the pipe is reset, so that the port of the pipe to be processed is in the position of the laser positioning sensor (392). S9. After the grinding is completed, the mechanisms are closed in sequence: the clamping cylinder (637) drives the arc-shaped clamping block (638) to reset, the stabilizing cylinder (52) drives the stabilizing block (53) to reset, and the operator or the matching unloading device takes out the processed pipe from the adjustment and positioning mechanism (6); then the loading mechanism (7), the laser cutting mechanism (3), and the grinding mechanism (4) are all reset to their initial positions to prepare for the next processing cycle of multi-specification pipes.
