Description

A cross laser positioning device for bench drilling

Technical Field

The invention relates to the technical field of laser positioning, and more particularly to a cross laser positioning device for bench drilling.

Background technique

The bench drill is a widely used small drilling machine. The motor drives the variable speed wheel, so that the main shaft of the drilling machine can obtain different speeds. The height of the drilling head frame on the machine column can be changed by adjustment, and the head frame can also be rotated around the column. The bench drill has a certain degree of flexibility, and the main shaft speed is high, the hole processing efficiency is high, and it is simple and convenient to use. It is mainly used for drilling, expanding, reaming, threading and other hole processing of small and medium-sized parts.

When drilling holes with a traditional bench drill, a line must be drawn on the workpiece to mark the location of the hole to be drilled, and then the drill head of the bench drill must be aligned with the workpiece to drill a pit first, and then the pit must be aligned with the marked drilling position. After alignment, the drill head to be processed is replaced and aligned with the pit to process the workpiece. However, during this process, the pit and the marked drilling position often need to be adjusted repeatedly many times before a qualified hole position can be located. This adjustment method is quite troublesome and time-consuming, and the hole position located is not accurate enough.

For example, Taiwan Patent No. M257245 discloses an adjustable laser alignment device for drilling machines. The laser alignment device includes a beam seat, an adjustment seat is installed on both sides of the beam seat, and a laser generator is installed in each adjustment seat. By rotating each adjustment seat, the laser beam of each laser generator can quickly adjust the position of the intersection to match the processing position of the workpiece. However, the structure of this patent is complicated, and during assembly, each laser generator must be installed on each adjustment seat first, and then each adjustment seat must be installed on the beam seat, and the assembly process is quite cumbersome.
