The commonly used clamps for drill holes on rocker drills have splints, flat pliers, and the like. For the single-piece and small-batch processing, the drilling operation steps are as follows: Before the drilling, according to the drilling position on the drawing, the centerline of the hole and the outline of the hole are drawn on the workpiece, and the center position of the hole and each Eye proofing on the circumference. Pre-drilled.
At the beginning of the drilling of the rocker, the worktable was manually adjusted to move the workpiece. The axis of the drill was coincided with the center of the workpiece hole visually, and then a shallow hole was drilled and the position of the hole was observed to be skewed. If the drill bit axis is aligned with the center of the hole, drilling can be performed. Drilling operation, for the through hole, when the drill is about to drill, the feedrate should be decelerated to prevent the drill from coming out of the hole and breaking the drill bit. If the accuracy of the hole pitch is higher, the center hole should be used as a guide. If it is a porous workpiece, you can use the dial on the dial of the milling machine table of the radial arm drill to control the movement distance of the table, accurately position the next hole according to its center distance, and also can refer to The scribe position of the hole further determines whether the hole position is correct.
If the pit is skewed, it should be calibrated. The method is: grind a few shallow grooves at the shallow hole and the distance between the scribe lines, and drop the drill to test. Do not drill until the hole is calibrated. For holes with a large workpiece diameter or equally divided circles, the workpiece can be clamped on a rotary table with a press plate for drilling. Before drilling, correct the vertical worktable and the workbench table perpendicularly, and correct the rotation axis of the circle bifurcation hole to coincide with the main axis of the rotary table.
The drilling operation step is to draw out the center line of each hole and the outline of the hole according to the requirements, and the sample is punched as required. After rubbing the surface of the machine, lubricate the bed surface. Install the rotary table and correct that the axis of the table is parallel to the axis of the milling head, and the distance between the two axes is 47.5 plus or minus 0.05 mm. Fasten it longitudinally and laterally. With the rotary table spindle, locate the center hole in the center of the disc workpiece. Place four equal-sized pads under the workpiece. Note that the position of the pad should avoid the drilling position and be pressed with the pressure plate and bolts. Install the drill on the rocker drilling and milling machine, adjust the rotary table so that the drill bit axis is aligned with the drilling center, and then tighten the rotary table. Open the cutting fluid and start drilling.
