5. after the first end 2-11 of the first workpiece is machined, after the tool of the chuck 2 is reset, the truss longitudinal beam 16 which firmly clamps the second workpiece moves downwards to the chuck 2, and the material taking cylinder 191 clamps the machined first end 2-11 of the workpiece to take down the workpiece; then the truss longitudinal beam 16 moves backwards to leave the chuck 2, leaves the rear gripper switching cylinder 19 and rotates 90 degrees anticlockwise, then the truss longitudinal beam 16 moves forwards to the chuck 2, the middle part of a second workpiece clamped by the feeding cylinder gripper 192 is placed on a support table 216 on the positioning support 215, the material ejecting cylinder 193 ejects, the end face of a second head 2-12 of the workpiece is abutted against the support table 217, the gripper 202 on the chuck 2 moves and clamps the middle part of the workpiece, the feeding cylinder gripper 192 releases the workpiece while the gripper 202 clamps the workpiece, and the two heads of the second workpiece face the same direction as the first head 2-11 of the first workpiece; then repeating the processing process of the first head 2-11 of the first workpiece, and processing the first head 2-11 of the second workpiece; when a second workpiece processes the first head 2-11, the first head 2-11 of the first workpiece clamped firmly by the truss longitudinal beam 16 returns to the position of the feeding part to carry out the conversion of the clamping position of the workpiece, the conversion of the clamping position of the workpiece is that the first head 2-11 of the first workpiece clamped firmly by the truss longitudinal beam 16 returns to the feeding part, and the workpiece is placed in the first clamping cylinder hand 7 to be clamped firmly; then the horizontal pushing cylinder 515 moves backwards to drive the first material clamping cylinder hand 7 arranged on the sliding seat 512 to move backwards, after the first material clamping cylinder hand 7 finishes the backward movement, the truss longitudinal beam 16 moves backwards, at this time, the material taking cylinder claw is dislocated with the workpiece, then the material taking cylinder claw moves downwards, and after the downward movement is finished, the material feeding cylinder claw is used for firmly clamping the second head 2-12 of the workpiece with the first head 2-11 processed in the first material clamping cylinder hand 7, so that the conversion of the clamping position of the workpiece is finished; after the clamping position conversion of the workpieces is completed, the truss longitudinal beam 16 moves upwards and then moves forwards to send the workpieces with the processed first ends 2-11 to the upper part of the chuck 2 for waiting, when the first ends 2-11 of the second workpieces are processed, the claw 191 of the material taking cylinder clamps the first ends 2-11 of the second workpieces, and the second workpieces are taken down;

6. the air source enters through the air pipe 303, the air source enters the air pipe 35 and then enters the cylinder body 210 through the air pipe joint 214, after the air source enters the cylinder body 210, because the two sealing rings 218 are arranged on the piston 212, a sealed chamber is formed between the piston 212 and the cylinder body 210, a certain pressure is formed in the chamber formed between the cylinder body 210 and the piston 212 after the air source enters, because of the pressure, the piston 212 is pushed forward, when the piston 212 is pushed forward, the return spring 221 is extruded forward to generate deformation shortening, the shortening distance of the return spring 221 is the forward movement distance of the piston 212, because the movable backer 222 is fixed with the piston 212, when the piston 212 is pushed forward, the movable backer 222 is driven to push forward, when the movable backer 222 is pushed forward, the adjusting backer 223 installed on the movable backer 222 is driven to push forward, thereby moving the adjusting screw 225 and the lock nut 226 forwards and ejecting; meanwhile, the claw hand converting cylinder 19 rotates 90 degrees anticlockwise, a first workpiece with the machined first head 2-11 is placed on the supporting platform 216 by the aid of the feeding cylinder claw hand 192, the ejection cylinder 193 ejects the workpiece to enable the machined first head 2-11 to be ejected on the adjusting screw 225, the clamping jaw 202 clamps the middle part 2-13 of the workpiece, then the main shaft 301 works to drive the clamping chuck 2 to rotate, and the cutter performs second head 2-12 machining on the first workpiece; when the first workpiece is processed with the second head 2-12, the truss longitudinal beam 16, the first material clamping cylinder hand 7, the horizontal pushing cylinder 515, the claw hand switching cylinder 19 and the material loading cylinder claw 191 repeat the action process of the first workpiece after the first head 2-11 is processed, the clamping position of the second workpiece is switched, and the second workpiece after the first head 2-11 is processed is sent to the upper part of the chuck for waiting after the position is switched; meanwhile, the feeding part repeats the working process in the process 1 and executes the feeding process of the first part of the second processing turn;

in the above process 6, the adjusting screw 225 is adopted to form the backer with the first head 2-11 when the second head 2-12 is processed, so that the problem that the gap between the end surface of the abutment 217 on the positioning backer 215 and the first head 2-11 of the processed workpiece is increased due to the fact that the outer diameter of the processed first head 2-11 is reduced, the first head 2-11 of the workpiece cannot abut against the abutment 217, and the processing precision of the workpiece is affected is avoided, that is, when the second head is processed, the adjusting screw 225 acts as the abutment 217; the reason why the first head 2-11 of the first workpiece which has been machined is directly pressed against the abutment 217 without using the ejector cylinder 193 is that the intermediate portion of the workpiece cannot be gripped by the jaws 202 because the end face of the abutment is too short and the outer diameter of the first head of the machined workpiece becomes small, and further, the second head 2-12 of the workpiece cannot be machined to the rearmost end because the intermediate portion of the workpiece cannot be gripped.

7. When the second head 2-12 of the first workpiece is machined, the truss longitudinal beam 16, the material taking cylinder claw 191, the claw switching cylinder 19 and the material loading cylinder claw 192 repeat the actions of the first workpiece when the first head 2-11 is machined, the first workpiece with the machined two heads is taken down, the second workpiece is loaded into the chuck by using the material loading cylinder claw, and only the loaded second workpiece is machined at the second head 2-12; after the second workpiece is loaded, the first workpieces at two ends are processed, the first workpieces are moved to the position of a conveying belt by the truss longitudinal beam 16 and the material taking cylinder claw 191, then the truss longitudinal beam 16 moves downwards to a position close to the conveying belt, then the material taking cylinder claw 191 is loosened, the workpieces are placed on the conveying belt 13, at the moment, the transmission motor 10 drives the transmission rotating shaft 11 to work, meanwhile, the conveying belt 13 is driven to work, and the conveying belt 13 conveys the finished workpieces to the finished product receiving hopper 14; after a first workpiece is placed on the conveying belt, the claw hand switching cylinder 19 rotates 90 degrees clockwise, then the first workpiece in the second working cycle is clamped by the first clamping cylinder hand 7 under the driving of the truss longitudinal beam 16, and the first workpiece is conveyed to the upper part of the chuck 2 to wait;

when one processed workpiece is conveyed to the conveying belt, the second head 2-12 of the second workpiece is processed at the same time, and the piston 212, the movable backer 222, the adjusting backer, the adjusting screw 225, the adjusting nut, the chuck 2 and the clamping jaws 202 repeat the action process of the first workpiece when the second head 2-12 is processed, so that the second head 2-12 of the second workpiece is processed;

8. when the second head 2-12 of the second workpiece is machined, the truss longitudinal beam 16, the material taking cylinder claw 19, the claw switching cylinder 19 and the material loading cylinder claw 192 repeat the action of the second head 2-12 of the first workpiece, take down the second workpiece with the machined second head, and mount the first workpiece which is machined for the second time for machining; at this time, the second workpiece with the second heads 2-12 machined is conveyed to the conveying belt 13 by the truss longitudinal beam 16 and the material taking cylinder claw 191 and conveyed to the finished product receiving hopper 14, so that the circulation of one machining process is completed, the machining of 4 heads of two workpieces by one machining process is completed, and the machining efficiency of the workpieces is improved; repeating the working process 1-8 for the subsequent workpiece;

according to the invention, the chuck with the cylinder body of the air cylinder is arranged on the machine tool, and the movable backer arranged on the piston in the cylinder body is provided with the adjusting backer, so that the right-angle joint can be used for processing two right-angle heads on the same chuck clamp of one machine tool; the gap distance between the end face of the rest table on the fixed rest and the first end of the machined workpiece of the workpiece is reduced due to the fact that the outer diameter of the machined first end is reduced when the right-angle joint workpiece is machined by adjusting the rest; specifically, the piston moves forwards to drive the movable backer to move forwards, so that the adjusting backer arranged on the movable backer is positioned on a first head of a workpiece, and the positioning of a second head of the workpiece during processing is realized; the gap distance between the end surface of the rest platform on the fixed backer and the first end of the processed workpiece is compensated; therefore, the problem of inaccurate processing precision of the right-angle joint workpiece is avoided, and the use effect of the right-angle joint workpiece and the sealing performance of the joint of the pipeline and the pipeline are improved;

the extension length of the adjusting screw rod can be adjusted by screwing the adjusting screw rod arranged in the adjusting threaded hole, so that the adjusting screw rod is suitable for processing workpieces with different diameters, and the limitation of processing the workpieces is avoided; when the difference between the diameter of the processed workpiece before processing and the diameter of the processed workpiece after processing is too large or too small, the adjusting screw rod can be controlled to retract into or extend out of the adjusting threaded hole by screwing, after the extending length of the adjusting screw rod is adjusted, the extending length of the adjusting screw rod is fixed by using a locking nut, and the locking nut is tightly attached to the movable backer, so that the adjusting screw rod is prevented from retracting into or falling out of the threaded hole in the processing process; the workpiece is continuously kept to advance in the horizontal material channel by adopting the linear vibrator in the feeding process, so that the feeding efficiency is improved; in the process, the fan-shaped turnover plate plays a role in loading, and when the turnover plate is turned over, the fan-shaped turnover plate also plays a role in stopping the workpieces in the horizontal material channel, so that the unprocessed workpieces are prevented from falling from the material channel; through the arranged proximity switch, when the right-angle processing workpiece approaches the proximity switch on the middle limiting block of the clamping claw of the second clamping cylinder hand, the linear vibrator automatically stops vibrating work, and when no workpiece exists in the clamping claw of the second clamping cylinder hand, the linear vibrator automatically starts vibrating work, so that the energy-saving effect is achieved, the production cost is reduced, and the working efficiency is improved;

the cylinder is arranged in the chuck gland, so that the movable backer is controlled to stretch and retract, the movable backer is convenient for processing of a workpiece process, and the movable backer retracts during the first processing process, so that the processing of the first process is prevented from being hindered;

the first material clamping cylinder hand and the second material clamping cylinder hand are matched, so that the transfer speed of the workpiece is increased, and the feeding and processing efficiency of the workpiece is improved;

the problem that the first end of the machined workpiece cannot be firmly propped by the short end face of the table is compensated by adjusting the bolt to firmly prop the first end of the machined workpiece;

the positioning backer seat is arranged on the chuck press cover, so that the positioning backer component is convenient to mount, the clamping position of a workpiece is fixed through the supporting platform and the backing platform arranged on the positioning backer, the supporting platform is used for preventing the workpiece from loosening downwards due to vibration during processing of the first head and the second head, and the backing platform is used for preventing the workpiece from inclining towards the chuck direction during processing of the first head;
