step three; after the end of the copper tube is closed under the rotation of the group 59, the displacement of the horizontal displacement mechanism 7 and the clamping of the lifting gripping device 3 can be reused to grip and displace the copper tube closed in the previous step to the inner side of the other group of fixed limiting grippers 84 and the movable limiting grippers 810 for limiting, so that the closed copper tube is inserted into the grinding circular table groove 52 for grinding and polishing, and meanwhile, the lifting gripping device 3 at the tail end grips a new group of copper tubes and places the closing circular table groove 58 for synchronous closing operation;
step four; after the copper pipe ground the burr in the round platform groove 52 of polishing, alright utilize the displacement of horizontal displacement mechanism 7 to drive lift grabbing device 3 and snatch three group's copper pipes simultaneously, utilize lift grabbing device 3 in the forefront to press from both sides the copper pipe clamp after will closing up and polish and get and place the oblique type stock guide, make the copper pipe guide that the processing of closing up collect, and all the other two sets of tongs then continue to snatch a new set of copper pipe and with the leading-in round platform groove 52 of polishing of copper pipe of closing up polish, realize that three group's synchronous motion's copper pipe snatchs, close up, polish and get rid of collection work.
Example 1, as shown in fig. 1-4, when the die for closing the copper tube needs to be replaced, the positioning of the cross-shaped fixture 55 and the cross-shaped frame 54 by the positioning pin 57 can be eliminated, then the cross-shaped fixture block 55 and the polishing circular platform groove 52 or the closing circular platform groove 58 can be taken out, the polishing circular platform groove 52 or the closing circular platform groove 58 wrapped by the cross-shaped fixture block 55 can be taken out at the moment, a new die is replaced for fixing, then the die is inserted into the cross frame 54 again under the wrapping of the cross fixture block 55, the structural bulge of the cross fixture block 55 and the concave layer of the cross frame 54 are used for positioning for guiding, finally, the positioning pin 57 is used for positioning, the die can be replaced, and the grinding circular table groove 52 and the closing circular table groove 58 are fixed more conveniently and stably, meanwhile, the channel 56 in the fixed die is automatically corrected with the absorption port of the shunt pipe 63, so that the copper scraps which are closed and polished can be absorbed conveniently.
The working principle is as follows: when the copper pipe is closed, firstly, the long copper pipe is cut into a plurality of groups of small sections, and the small copper pipes are uniformly arranged in the material collecting groove, then the horizontal displacement mechanism 7 is controlled by the control console 4 to drive the three groups of lifting gripping devices 3 to horizontally displace, so that the tail lifting gripping device 3 clamps the end of the copper pipe to move, during the process, the driving of the servo motor 85 drives the bevel gear set 862 structure to be meshed, so that the bidirectional screw rod 863 centrifugally rotates, the two groups of movable limiting grippers 810 can be driven to mutually approach and open along with the rotation of the bidirectional screw rod 863, at the moment, the copper pipe can be placed on the inner layer of the fixed limiting gripper 84, then the movable limiting gripper 810 and the fixed limiting gripper 84 are driven to be closed by utilizing the reverse rotation of the servo motor 85 to limit the copper pipe, and then the whole mounting platform 83 is driven to horizontally displace downwards by the actuation of the hydraulic cylinder 82 under the guidance of the guide rail 81, the mounting table 83 is prompted to drive the end of the copper tube to be inserted into the closing-up circular table groove 58 under the limiting effect, pressure is continuously applied, the circular table fixture block on the end face of the rotating rod 89 is prompted to be inserted into the inner diameter of the other end of the copper tube to form positioning, at the moment, the belt transmission mechanism 88 is driven to perform belt transmission through the starting of the driving motor 87, the two groups of rotating rods 89 are forced to rotate simultaneously, and therefore the copper tube inserted into the grinding circular table groove 52 is subjected to closing-up work;
after the end of the copper pipe is closed, the structure of the synchronous clamping mechanism 86 can be repeatedly started to open the two groups of movable limiting grippers 810, at the moment, the closed copper pipe is clamped out by the lifting gripping device 3 positioned at the middle position, then, the closed copper pipe is placed in the other group of fixed limiting grippers 84 and movable limiting grippers 810 by utilizing the displacement of the horizontal displacement mechanism 7, at the moment, the closed copper pipe can be inserted into the polishing circular platform groove 52, the rotation of the copper pipe is matched, the closing part of the end of the copper pipe is polished, the burrs on the surface of the closing part are removed, during the period, the copper scraps generated by cutting the closing part and polishing the copper pipe in the polishing circular platform groove 52 and the closing circular platform groove 58 are promoted to be absorbed by the suction fan 61 and the suction pipe 62 is communicated with the shunt pipe 63, the closing part and the polishing effect of the copper pipe are improved, meanwhile, when the lifting gripping device 3 at the middle position clamps the closed copper pipe to displace, the last lift grabbing device 3 then presss from both sides again and gets new copper pipe and carry out the work of closing up, and the lift grabbing device 3 of foremost is then pressed from both sides the copper pipe of getting after polishing to utilize three groups lift grabbing device 3 to realize that the synchronous clamp of copper pipe is got, is closed up, is polished and the collection work of discharging.
Finally, it should be noted that the above-mentioned contents are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, and that the simple modifications or equivalent substitutions of the technical solutions of the present invention by those of ordinary skill in the art can be made without departing from the spirit and scope of the technical solutions of the present invention.
