Description

Pillowcases drilling frock

Technical Field

The utility model relates to a sleeper pole drilling frock.

Background

The sleeper column of the coal transport vehicle is made of extruded and expanded aluminum profiles, is in a shape of a Chinese character 'ji' (as shown in figure 1), is divided into a left symmetrical part and a right symmetrical part, 32-phi 17 through holes need to be drilled at two wings of the sleeper column, and the hole pitch of each hole is required to be within +/-0.5 mm. The production bottleneck is caused by the fact that the workpieces are long and the holes are multiple, and the processing cost and the processing efficiency are high. According to the traditional machining method, a large numerical control planer type milling machine is adopted, a pillow column is pressed on a working platform, and numerical control machining is conducted through programming.
