The specific implementation of the double drilling equipment of the embodiment is as follows:
firstly, battens with two ends cut at an angle of 45 degrees are placed into a bin 210 of a feeding mechanism 200, then, the battens at the bottommost layer at a discharge port of the bin 210 are pushed onto a drilling platform 110 by using a material pushing cylinder 220, and the material pushing cylinder 220 returns after the battens enter a drilling station;
controlling the drilling mechanisms 300 provided with the drill bits 310 on the left side and the right side of the drilling station to move towards the center, and driving the sliding block 332 and the V-shaped stop block 340 connected with the sliding block 332 to move towards each other by using the opposite clamping cylinder 333 to clamp the workpiece on the drilling platform 110 from two ends; meanwhile, the pressing cylinder 420 on the pressing mechanism 400 is controlled to drive the wedge block 430 to move towards one side close to the workpiece, so that the roller 450 is driven to slide upwards, and the pressing block 460 at the end part of the lever 440 is used for pressing the middle part of the batten; after the two ends of the batten are clamped and the upper part of the batten is pressed tightly, the drill bit 310 is driven to move downwards by the lifting moving mechanism 320 and the drill bit motor 311 is used for drilling, so that the two ends of the workpiece are positioned and drilled synchronously, and the drilling precision of the two ends of the workpiece can be effectively improved;
after drilling at two ends of the batten is finished, the pressing mechanism 400 drives the wedge block 430 to retreat so that the pressing block 460 loosens to press the batten, meanwhile, the material returning cylinder 520 on the workbench 100 drives the sliding seat 511 to move towards one side away from the drilling station to drive the pressing mechanism 400 and the drilling platform 110 to retreat from the drilling station, at this time, the opposite clamping cylinder 333 retreats towards two sides to loosen the clamped batten, and the batten cannot move along the retreating direction of the material returning cylinder 520 due to the limiting function of the long material stopping edge 342 of the V-shaped stop block 340, so that in the process that the material returning cylinder 520 retreats the drilling platform 110, the batten completing drilling falls down from the drilling station to fall onto the material groove 530, and the whole drilling process of one workpiece is finished;
after the workpiece falls into the trough 530, the drilling platform 110 gradually moves to a side close to the drilling station under the action of the material returning cylinder 520 until the workpiece is located at the drilling station, and the process cycle of feeding, positioning, drilling and pushing of a second workpiece is prepared to enter, so that full-automatic processing is realized.
