Abstract
Description
Technical Field
[0001] The utility model relates to the field of power tool holder devices, in particular to an adjustable power tool holder. Background Art
[0002] A driven toolholder is a toolholder mounted on a powered turret and driven by a servo motor. This type of toolholder is typically used on milling machines, though a few are also used on machining centers with powered turrets. Driven toolholders are generally categorized as VDI, BMT, and custom-designed.
[0003] Currently, the steps for adjusting the angle of the BMT universal power tool holder during workpiece machining are: first loosen the screws at the bottom of the universal tool holder with a wrench, then loosen the two screws on the universal tool holder dial with a wrench, manually adjust the tool holder to a suitable angle, and then tighten the screws at the bottom of the universal tool holder and the screws on the tool holder dial respectively with a wrench. The above method of adjusting the angle of the BMT universal power tool holder with special tools such as wrenches requires loosening the screws that limit the power tool holder one by one, which is cumbersome, time-consuming and labor-intensive, resulting in low efficiency in the angle adjustment of the BMT universal power tool holder. In addition, since the angle adjustment of the BMT universal power tool holder during workpiece machining is a high-frequency action, the screws may easily be stripped in the process of repeatedly tightening the screws that limit the rotation of the tool holder, resulting in the BMT universal power tool holder being difficult to be firmly fixed after the angle adjustment, causing the power tool holder to easily deflect during the workpiece machining process, thereby affecting the workpiece machining quality.
