Description

TECHNICAL FIELD

[0001] The utility model relates to power tool holder technical field, concretely is angle adjustable power tool holder. BACKGROUND

[0002] Power tool holder refers to the tool holder installed on the power tool tower, which can be driven by a servo motor. This kind of tool holder is generally applied to turning and milling combined machines, and a small number of them can be applied to machining centers with power tool towers. With the increasing complexity of workpieces, precision levels and processing efficiency, multi-axis and high speed have become essential conditions for machine tools.

[0003] According to the angle adjustable power tool holder (announcement number: CN219152146U) disclosed in the above-mentioned application, the angle of the tool holder can be adjusted during use by adjusting the linkage between the adjusting bolt, nut, turntable, pointer and scale. When a new tool bit needs to be replaced, the tool bit can be quickly replaced by adjusting the pressure cap, thereby improving the use efficiency of the device.

[0004] However, the adjusting mechanism of the above-mentioned device relies on the thread cooperation between the adjusting bolt and the nut in actual use. Long-term repeated adjustment will cause wear and tear of the thread pair and increase the gap. Under the action of cutting vibration and axial load, microslip may occur in the threaded connection, causing angle deviation. Especially during high-speed machining, dynamic load will accelerate thread fatigue, eventually leading to a decrease in the rigidity of the adjusting mechanism or even complete failure. In view of this, we propose an angle adjustable power tool holder. UTILITY MODEL CONTENTS
