Description

A CNC Drilling Fixture Convenient for Installation and Adjustment

technical field

The utility model belongs to the technical field of drilling machine clamp devices, in particular to a numerically controlled drilling machine clamp which is convenient for installation and adjustment.

Background technique

There are certain defects in the use of existing drilling fixtures: the clamping block is designed with a hard material, and when the cylindrical or polygonal workpiece is clamped in the middle, the force-bearing area is small and it is not easy to adjust, resulting in Misalignment may occur, causing the workpiece to fail to be drilled and the workpiece to be scrapped.

Existing drilling machines need to perform drilling operations on workpieces. There are the following disadvantages: accurate alignment is required so that the hole to be drilled corresponds to the long groove on the workbench, otherwise there will be the disadvantage of drilling through the workbench, which is not convenient for the adjustment of the drilling machine fixture; it will affect the service life of the equipment; simply Relying on the long groove on the workbench, it is difficult to fix the work, which affects the processing effect; when the long groove is used for drilling, when the diameter of the drill hole is larger than the width of the long groove, the standard workbench cannot be used for processing, which reduces the Equipment usage. In addition, there are some relatively simple drilling machines, which directly place the workpiece on the ground to drill holes, which is not only difficult to fix the workpiece, but also damages the ground during the drilling operation. Therefore, it is necessary to provide a reliable and easy-to-adjust fixture for the drilling work of the drill press.
