As shown in fig. 4, the working principle of the double-station rotary clamp for finely turning the semi-circle of the brake base is as follows:
before the brake base is placed on the rotary clamp, the hydraulic control system returns oil to the horizontal clamping device, the sequence valve 2 controls the action sequence of the horizontal clamping device according to the pressure of a first branch loop, the floating support head 23 moves towards the inner parts of the first positioning seat 6 and the second positioning seat 13 under the action of the spring in the pressing cylinder 15, the pressing plate 7 on one side of the floating support head 23 is not acted by the floating support head 23, two ends of the pressing plate 7 are in a loose state, and the floating support heads 23 on the second horizontal supporting cylinder 21, the push cylinder seat 11 and the first horizontal supporting cylinder 22 are also in an oil return state under the action of the hydraulic control system and are kept at an initial position.
The hydraulic system supplies oil to the vertical clamping device, the sequence valve 2 controls the action sequence of the vertical clamping device according to the pressure of the second branch loop, the piston rod 17 drives the pull rod 20 to move inwards under the action of oil pressure, and the expansion sleeve 19 arranged outside the pull rod 20 is not acted by the pull rod 20 at the moment, does not bounce outwards and is in an initial position. Then the brake base 8 is arranged on a rotary clamp, a round table protruding in the middle of the brake base 8 is embedded in a gap between the expansion sleeve 19 and the positioning support 4, oil is supplied to the horizontal clamping device under the control of a hydraulic system, an internal branch loop of the sequence valve is subjected to oil pressure, so that the horizontal clamping device is controlled, the floating support head 23 moves towards the outside of the first positioning seat 6 and the second positioning seat 13 under the action of a spring inside the pressing cylinder 15, one end of the pressing plate 7 on one side of the floating support head 23 is jacked up under the action of the floating support head 23, and the other end of the pressing plate 7 moves towards the inner side due to the lever principle, so that the right end face of the brake base is jacked. The second horizontal supporting cylinder 21, the cylinder pushing seat 11 and the first horizontal supporting cylinder 22 are also in an oil supply state under the action of the hydraulic control system, and the floating support head 23 is driven to move by the springs in the cylinder pushing seat 11 and the second horizontal supporting cylinder 21, so that the front end face and the rear end face of the brake base 8 are fixed.
Meanwhile, the hydraulic system returns oil to the vertical clamping device, the piston rod 17 drives the pull rod 20 to move inwards, the expansion sleeve 19 is bounced outwards by extrusion force caused by the movement of the tail end of the pull rod 20, and the expansion sleeve and the positioning support 4 clamp a circular boss in the middle of the brake base 8, so that the brake base 8 is fixed in the vertical direction. Secondly, the cutter is replaced by the boring cutter 25 by the cutter head, and the double-station rotary clamp arranged on the main shaft moves in the circumferential direction around the main shaft of the lathe to finish the semi-circle finish turning. And thirdly, the hydraulic system returns oil to the horizontal clamping device, the horizontal clamping device returns to the initial state, meanwhile, oil is supplied to the vertical clamping device, the piston rod 17 drives the pull rod 20 to move outwards, the force of the pull rod on the expansion sleeve 19 is withdrawn, the expansion sleeve 19 returns to the initial position, and the brake base 8 is released. And finally, taking down the brake base 8, thereby completing the double-station semi-circle finish turning process.
