Description

A guiding and positioning device for a numerically controlled drilling machine

Technical Field

The utility model relates to the technical field of mechanical processing equipment, in particular to a guiding and positioning device for a numerically controlled drilling machine.

Background Art

A drilling machine refers to a machine tool that mainly uses a drill to process holes on a workpiece. Usually, the drill bit rotates as the main motion, and the drill bit moves axially as the feed motion. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream or tap. When drilling holes on workpieces, existing drilling machines often cause errors in the drilling position of the workpiece due to loose fixation of the workpiece, as well as low drilling accuracy, which ultimately leads to the scrapping of the workpiece and increased costs.

After searching, the Chinese patent public number is: CN212191396U, which discloses a workpiece positioning fixture for a CNC drilling machine. By setting a movable clamping plate device and cooperating with a fixed clamping plate, the workpiece can be clamped in the horizontal direction. At the same time, the auxiliary positioning device can be used to clamp the workpiece in the vertical direction, thereby improving the effect of fixing and clamping the workpiece. The rectangular inner cylinder can adjust the height in the vertical direction in the rectangular hollow outer cylinder, and the auxiliary rod can adjust the position in the horizontal direction in the waist-shaped through hole, so that the auxiliary rod can be used for auxiliary pressing of workpieces of different heights and sizes, and has stronger adaptability. The trapezoidal auxiliary block and the rectangular auxiliary block are movably arranged in the isosceles trapezoidal groove and the rectangular groove, which is convenient for installation according to needs, and is beneficial to improving the tightness of the contact between the clamping block and the workpiece, so that the clamping effect of the workpiece is more stable.

However, when processing the workpiece, the workpiece is in direct contact with the baffle, and the workpiece will generate a large vibration force during processing, which will cause the contact surface of the baffle and the workpiece to rub, thereby causing scratches on the surface of the workpiece, thereby reducing the quality of the workpiece. At the same time, when facing workpieces of different shapes, it is necessary to select a suitable clamping plate according to the situation to ensure the stability of the workpiece during processing. However, the clamping plate is mostly installed by bolts, which makes it inconvenient for the staff to replace the clamping plate, thereby reducing the work efficiency of the staff and also reducing the processing efficiency of the workpiece.
