A third motor 532 is connected to the side wall of the fixed frame 515, a third gear 533 is connected to the motor shaft of the third motor 532 after passing through the wall of the fixed frame 515, and the third gear 533 meshes with the third straight rack 531. The third sliding table 530 is connected to the horizontal clamping member 540 through a connecting shaft 570 and fastened by bolts. The horizontal clamping component 540 includes a clamping side plate 541, a clamping seat 542, and a clamping arm 543. The two clamping side plates 541 are vertically arranged and fixed on the outer sides of the two clamping seats 542 respectively. The bottom is provided with a sliding groove, the clamping arm 543 is U-shaped as a whole and the upper end is slidably connected with the sliding groove, and the lower end encloses a circular clamping hole 544.
[0043] Among them, the PLC controller 440 is electrically connected to the first position sensor 411, the second position sensor 412, the third position sensor 511, the fourth position sensor 512, and the warning light 421. The PLC controller 440 is electrically connected to the first motor 422, the second Both the motor 423 and the third motor 532 are electrically connected. When the top of the second sliding table 510 is 3-5 cm away from the first position sensor 411 and the second position sensor 412 at the bottom of the sliding seat 420, the first position sensor 411 and the second position sensor 412 will generate signals and transmit them to the PLC controller 440 , The PLC controller 440 sends an alarm signal to the alarm light 421 and controls the second motor 423 to turn off; when the side wall of the sliding seat 420 is 3-5 cm away from the third position sensor 511 and the fourth position sensor 512, the third position sensor 511 And the fourth position sensor 512 will generate a signal and transmit it to the PLC controller 440. The PLC controller sends an alarm signal to the alarm lamp 421 and controls the first motor 422 to turn off.
[0044] The working method of the high-precision mechanical arm for lathes in this embodiment is as follows:
[0045] S1. Turn on the second motor 423, the motor shaft of the second motor 423 drives the second gear 425 to rotate, the second gear 425 drives the first straight rack 460 meshed with it to move in the vertical direction, and the first elongated slider 426 moves in the vertical direction along the vertical sliding column 450, so that the sliding seat 420 and the X-axis clamping mechanical arm 500 move in the vertical direction;
[0046] S2. When the X-axis clamping robot arm 500 moves to the processing position, turn off the second motor 423, turn on the first motor 422, the motor shaft of the first motor 422 drives the first gear 424 to rotate, and the first gear 424 drives it to mesh with it The second straight rack 560 moves in the horizontal direction, and the second long slider 513 moves in the horizontal direction along the horizontal sliding column 550, so that the third sliding table 530 and the horizontal clamping member 540 move in the horizontal direction;
[0047] S3. When the horizontal clamping member 540 moves to the processing position, the first motor 422 is turned off, and the third motor 532 is turned on. The motor shaft of the third motor 532 drives the third gear 533 to rotate, and the third gear 533 drives the third gear 533 meshing with it. The three straight racks 531 move in the horizontal direction, so that the horizontal clamping member 540 moves in the horizontal direction;
[0048] S4. When the horizontal clamping part 540 moves to the position to be processed, the part to be processed or the finished part is inserted into the clamping hole 544, and the clamping arm 543 clamps the part tightly, which is convenient for the turning tool of the lathe to process the part. Or remove the finished parts.
[0049] When the top of the second sliding table 510 is 3-5 cm away from the first position sensor 411 and the second position sensor 412 at the bottom of the sliding seat 420, the first position sensor 411 and the second position sensor 412 will generate signals and transmit them to the PLC controller 440 , The PLC controller 440 sends an alarm signal to the alarm light 421 and controls the second motor 423 to turn off; when the side wall of the sliding seat 420 is 3-5 cm from the third position sensor 511 and the fourth position sensor 512, the third position sensor 511 And the fourth position sensor 512 will generate a signal and transmit it to the PLC controller 440. The PLC controller sends an alarm signal to the alarm lamp 421 and controls the first motor 422 to turn off. The PLC controller 440 accurately controls and alarms the moving distance, which greatly improves the safety of the mechanical arm and avoids the occurrence of safety accidents in lathe operation.
