According to the operation platform, the operation platform can be applied to a processing station of a vertical lathe, when the clamping manipulator 700 clamps a workpiece to finish single-sided processing on the vertical lathe, the workpiece is required to be clamped for processing the other side, and at the moment, the operation platform is matched with the clamping manipulator 700 to finish surface replacement clamping of the workpiece. Reference may be made to the following specific steps:
In operation, first, the pneumatic push rod 410 drives the workpiece platform 200 to rise to a high position (as shown in fig. 9), the clamping manipulator 700 lifts the workpiece 600 with single-sided processing completed and passes through the notch to be positioned, then the clamping jaws of the clamping manipulator 700 are tightened to cancel clamping of the workpiece 600, and the workpiece 600 is released and placed on the platform bracket 210;
After the clamping manipulator 700 releases the workpiece 600, the workpiece 600 is removed from the lower part of the workpiece platform 200, the pneumatic push rod 410 drives the workpiece platform 200 to descend to the low position (as shown in fig. 12), then the clamping manipulator 700 moves to the upper part of the workpiece platform 200, and clamps the workpiece 600 again, so that the surface replacement clamping is completed, and finally, the clamping manipulator 700 can remove the workpiece 600 (as shown in fig. 13) and transfer to the vertical lathe to process the other surface of the workpiece 600.
Therefore, the operation platform can be matched with the manipulator 700 to finish the clamping processing of the workpiece surface, and the problem that the manipulator 700 cannot clamp due to the limitation of the movable space range can be solved because the workpiece platform 200 can be lifted to adjust the position, so that the manipulator 700 can easily finish the clamping of the workpiece surface. Meanwhile, the operation platform avoids the operation of manually overturning the workpiece to clamp, reduces the waiting time of stopping and clamping, and improves the working efficiency.
In a further embodiment, an elastic buffer device 500 is further provided between the work platform 200 and the driving device 400 of the operation platform. Specifically, the elastic buffer 500 includes a first connection block 510, a first slider 520, a second connection block 530, and a spring assembly 540, the first slider 520 is fixedly connected with the first connection block 510, the spring assembly 540 includes a spring fixing screw 541 and a pressure spring 542, the spring fixing screw 541 is connected between the first connection block 510 and the second connection block 530 through a nut, and the pressure spring 542 is sleeved on the spring fixing screw 541. The elastic buffer 500 is slidably engaged with the guide rail 300 through a first slider 520, the first connecting block 510 is fixedly connected with one end of the pneumatic push rod 410, and the second connecting block 530 is fixedly connected with the second slider 240 of the work platform 200.
According to the elastic buffer 500, the work platform 200 is supported by elastic force, and the work platform 200 is provided with a pressed buffer distance. According to the operation platform with the elastic buffer 500, in operation, when the manipulator 700 is to place the workpiece 600 on the platform bracket 210, the manipulator can pass through the notch to fix the position, then drive the workpiece 600 to move downwards together by a proper distance (as shown in fig. 10), then release the workpiece, and then the pressure spring 542 of the elastic buffer 500 can slowly push up the platform bracket 210 upwards by elasticity (as shown in fig. 11).
In the above embodiment, the elastic buffer 500 is installed between the pneumatic push rod 410 and the workpiece stage 200, and the above processing operation is advantageous in that since different workpieces have different thicknesses, if the robot 700 does not move downward and the position of the workpiece is released, the workpiece may drop down onto the stage support 210 due to insufficient thickness, which may easily cause positional deviation. The elastic buffer device 500 makes the workpiece platform 200 have a pressed buffer distance, so that the manipulator 700 descends for a distance and then loosens the workpieces, each workpiece can be guaranteed to be stably placed on the platform support 210 and then loosens, the workpieces can be prevented from being shifted, and therefore the position accuracy of the workpiece during face changing and clamping can be guaranteed. Meanwhile, the control program of the manipulator 700 can be universal for clamping workpieces with different specifications, so that the problem that the programming of the manipulator 700 is difficult when a plurality of vertical lathes process different workpieces can be avoided.
