[0002] In the field of mechanical processing, CNC machine tools play an important role, enabling high-precision machining of workpieces to meet the needs of various industrial production. Among them, CNC lathes have a wide range of applications, providing efficient production and precise quality control for parts turning needs.

[0003] In existing CNC turning machines, such as Chinese patent application CN119609179A, when the user pulls the lifting frame upward, the movable seat and the push plate can automatically move by the elastic force of the first spring and the second spring, so that the support plate can be lifted and the worm workpiece can be ejected onto the support plate. Through the movement of the movable base, one end of the worm workpiece can be clamped on the three-jaw chuck assembly, and when the ejector assembly positions the other end of the worm workpiece, the movable seat and the push plate can be pushed backward to compress the first spring and the second spring again, so that the movable seat and the push plate can continue to work in the next cycle. This assembly and positioning method of the worm workpiece is simple and convenient, does not require the user to perform too many complicated operations, and improves the processing efficiency of the worm.

The clamping part 3001 deflects out from the opening of the body 1 and presses against the lifting platform 319 to press down the lifting platform 319. The conveying system transfers a ball valve core to the lifting platform 319. After the ball valve core is moved to the lifting platform 319, the clamping part 3001 clamps and fixes the ball valve core, and carries the ball valve core to the processing position. The turning head 26 turns the ball valve core on the clamping part 3001, and the processed ball valve core is sent back to the lifting platform 319.

[0049] Furthermore, a rotating mechanism is provided next to the clamping member 39, which drives the clamping member 39 to rotate to meet the needs of turning processing. Specifically, the rotating mechanism can be a gear ring power transmission structure, that is, the clamping member 39 is connected to the bearing seat, and a gear ring is fixed on the clamping member 39, which is connected to the power source, so that the rotating mechanism drives the clamping member 39 to rotate to drive the ball valve core to rotate. This structure is a prior art in this field and will not be elaborated here.

[0050] Furthermore, a second rotating arm 311 is rotatably engaged on the other side of the top of the gear disc 34, and the second rotating arm 311 extends to the processing position in the machine body 1.

[0051] Furthermore, during turning processing, the ball valve core needs to be translated, so it is necessary to add a translation structure to the clamping part 3001 in the equipment. Specifically, a translation structure can be provided on the gear disc 34, and the first rotating arm 37 and the second rotating arm 311 are both provided on the translation structure, so that during processing, the translation requirements of the ball valve core can be met; the translation structure can be a rack and pinion structure, the rack is slidingly provided on the gear disc 34, the first rotating arm 37 and the second rotating arm 311 are provided on the rack, the gear and the rack are engaged, and the driving source drives the gear to rotate, thereby achieving the translation function.

[0052] Furthermore, a fixed frame 315 is provided next to the body 1. The fixed frame 315 is divided into two parts and is arranged adjacent to each other. A plurality of conveying rollers 316 are rotatably matched on the fixed frame 315. The conveying rollers 316 on each part of the fixed frame 315 are tensioned with a conveyor belt 317. The conveyor belt 317 is located between the two parts of the fixed frame 315. A conveying motor 318 is fixedly installed on the two parts of the fixed frame 315. The conveying motor 318 is power-connected to the conveying rollers 316. A lifting platform 319 is provided between the conveyor belts 317 on both sides. The lifting platform 319 is located above the conveyor belt 317. The lifting platform 319 is located on the deflection trajectory of the clamping member 39.

The conveying system of the ball valve core includes a conveyor belt 317.

[0053] Among them, when the ball valve core is transferred from the conveying system to the processing position, the conveying system is first used to transfer the ball valve core to the conveyor belt 317, and the conveying motor 318 is started. The conveying motor 318 drives the conveying roller 316 to rotate, and the conveying roller 316 drives the conveyor belt 317 to rotate. The conveyor belt 317 stops before transferring the ball valve core to the lifting platform 319, and then the shaft cylinder 33 is started. The shaft cylinder 33 drives the turntable 32 to deflect on the bracket 31, so that the turntable 32 drives the first rotating arm 37 and the second rotating arm 311 to rotate out of the opening of the machine body 1, and the first motor 38 is started. The first motor 38 drives the first rotating arm 37 to deflect, so that the first rotating arm 37 presses against the lifting platform 319, the lifting platform 319 presses the spring telescopic rod 320 to move down, so that the lifting platform 319 is under the conveyor belt 317, and the conveyor belt 317 continues to move a ball valve core to the lifting platform 319, that is, it reaches the front of the clamping member 39, and then the second motor 312 is started. The second motor 312 drives the second rotating arm 311 to deflect to the lifting platform 319, and the hydraulic cylinder 310 and the telescopic cylinder 314 are started. The telescopic cylinder 314 drives the pusher 313 to push the ball valve core onto the clamping member 39. The hydraulic cylinder 310 drives the clamping member 39 to clamp and fix one end of the ball valve core, while the pusher 313 and the clamping member 39 clamp and fix the ball valve core, and then the turntable 32 drives the first rotating arm 37 and the second rotating arm 311 to return to the processing position. At this time, if the end of the ball valve core is turned, the second rotating arm 311 drives the push piece 313 to move away from the ball valve core, and the turning head 26 is used to turn the ball valve core. If the side of the ball valve core is turned, the servo motor 36 is started, the servo motor 36 drives the power gear 35 to rotate, the power gear 35 drives the gear plate 34 to rotate, and the gear plate 34 drives the first rotating arm 37 and the second rotating arm 311 to rotate, so that the side of the ball valve core between the clamping piece 39 and the push piece 313 faces the turning head 26, and the turning head 26 then turns the side of the ball valve core. The surface is turned, and the processed ball valve core is then sent back to the lifting platform 319 by the first rotating arm 37 and the second rotating arm 311, and the lifting platform 319 is also pressed down. At this time, the existing clamping member 39 loosens the fixation of the ball valve core, and the first rotating arm 37 is removed from the lifting platform 319. The pushing member 313 pushes the processed ball valve core away from the lifting platform 319, so that the processed ball valve core falls behind the conveyor belt 317, and then the first rotating arm 37 is again against the lifting platform 319, the second rotating arm 311 is removed from the lifting platform 319, and the conveyor belt 317 transfers the next ball valve core to the lifting platform 319 and performs the turning process of the next ball valve core.

[0054] The overall working principle of CNC turning machine tools:

[0055] The ball valve core is transported to the lifting platform 319 by the conveying system of the ball valve core and stops moving. The clamping member 3001 deflects out from the opening of the body 1 and presses against the lifting platform 319 to press down the lifting platform 319. The conveying system transfers a ball valve core to the lifting platform 319. After the ball valve core is moved to the lifting platform 319, the clamping member 3001 clamps and fixes the ball valve core and carries the ball valve core to the processing position. The turning head 26 turns the ball valve core on the clamping member 3001. The processed ball valve core is then sent back to the lifting platform 319. The conveying system then removes the processed ball valve core and moves the next ball valve core to the lifting platform 319. This replaces the semi-automatic processing method of the manually assisted CNC turning machine, eliminates the fixed error when the ball valve core is manually placed, avoids the error affecting the processing accuracy, improves the processing efficiency of the equipment, and improves the processing accuracy of the equipment.

[0056] Before turning, the hydraulic rod 28 is started, and the hydraulic rod 28 extends to drive the sliding door 27 to move, so that the sliding door 27 is removed from the opening of the machine body 1. The clamping member 3001 is then deflected and rotated out of the opening of the machine body 1. After clamping and fixing a ball valve core on the conveying system, the clamping member 3001 is rotated back to the processing position in the machine body 1. Then, the sliding door 27 is reset to close the opening of the machine body 1, and the stepping motor 25 is started. The stepping motor 25 drives the screw 24 to rotate, and the screw 24 drives the linkage member 23 to move. The linkage member 23 drives the movable frame 22 to move on the slide rail 21. The movable frame 22 drives the turning head 26 to move so that the turning head 26 is close to the ball valve core for turning.

[0057] When the ball valve core is transferred from the conveying system to the processing position, the conveying system is first used to transfer the ball valve core to the conveyor belt 317, and the conveying motor 318 is started. The conveying motor 318 drives the conveying roller 316 to rotate, and the conveying roller 316 drives the conveyor belt 317 to rotate. The conveyor belt 317 stops before transferring the ball valve core to the lifting platform 319, and then the shaft cylinder 33 is started. The shaft cylinder 33 drives the turntable 32 to deflect on the bracket 31, so that the turntable 32 drives the first rotating arm 37 and the second rotating arm 311 to rotate out of the opening of the machine body 1, and the first motor 38 is started. The first motor 38 drives the first rotating arm 37 to deflect, so that the first rotating arm 37 presses against the lifting platform 31 9, the lifting platform 319 presses the spring telescopic rod 320 to move downward, so that the lifting platform 319 is under the conveyor belt 317, and the conveyor belt 317 continues to move a ball valve core to the lifting platform 319, that is, in front of the clamping member 39, and then the second motor 312 is started. The second motor 312 drives the second rotating arm 311 to deflect to the lifting platform 319, and the hydraulic cylinder 310 and the telescopic cylinder 314 are started. The telescopic cylinder 314 drives the pusher 313 to push the ball valve core onto the clamping member 39. The hydraulic cylinder 310 drives the clamping member 39 to clamp and fix one end of the ball valve core, while the pusher 313 and the clamping member 39 clamp and fix the ball valve core, and then the turntable 319 is turned. After the first rotating arm 37 and the second rotating arm 311 are driven to return to the processing position, if the end of the ball valve core is turned, the second rotating arm 311 drives the pusher 313 to move away from the ball valve core, and the turning head 26 is used to turn the ball valve core. If the side of the ball valve core is turned, the servo motor 36 is started, the servo motor 36 drives the power gear 35 to rotate, the power gear 35 drives the gear plate 34 to rotate, and the gear plate 34 drives the first rotating arm 37 and the second rotating arm 311 to rotate, so that the side of the ball valve core between the gripping member 39 and the pusher 313 faces the turning head 26, and the turning head 26 then turns the side of the ball valve core. After turning, the processed ball valve core is sent back to the lifting platform 319 by the first rotating arm 37 and the second rotating arm 311, and the lifting platform 319 is also pressed down. At this time, the existing clamping member 39 releases the fixation of the ball valve core, and the first rotating arm 37 is removed from the lifting platform 319. The pushing member 313 pushes the processed ball valve core away from the lifting platform 319, so that the processed ball valve core falls behind the conveyor belt 317, and then the first rotating arm 37 is again against the lifting platform 319, the second rotating arm 311 is removed from the lifting platform 319, and the conveyor belt 317 transfers the next ball valve core to the lifting platform 319 and performs the turning process of the next ball valve core.

[0058] A ball valve core processing process, using the above-mentioned CNC turning machine tool, includes the following steps:

[0059] S1: The ball valve core is transported to the conveyor belt 317 by the conveying system of the ball valve core. The ball valve core moves on the conveyor belt 317 and stops before it reaches the lifting platform 319.

[0060] S2: The clamping member 3001 deflects out from the opening of the body 1 and abuts against the lifting platform 319 to press down the lifting platform 319. After the lifting platform 319 is lower than the conveyor belt 317, the conveyor belt 317 transfers a ball valve core to the lifting platform 319.

[0061] S3: After the ball valve core is moved to the lifting platform 319, the clamping member 3001 clamps and fixes the ball valve core, and deflects the ball valve core to the processing position;

[0062] S4: The turning head 26 performs turning processing on the ball valve core on the clamping member 3001;

[0063] S5: The processed ball valve core is sent back to the lifting platform 319, and the processed ball valve core is removed by the conveyor belt 317, and the next ball valve core is moved to the lifting platform 319 at the same time.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
