Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a detachable milling cutter holder device. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] Chinese Patent No. CN 211867136 U discloses a fixing device for milling cutters, including a support platform, a fixing frame on the support platform, and a motor mounted on the fixing frame. The output shaft of the motor is connected to the fixing device, and the fixing device is connected to the milling cutter. The fixing device includes a fixing block with a slot for easy insertion of the milling cutter. Locking bolts are located on both sides of the fixing block, with the tops of the locking bolts inserted into mounting holes on the milling cutter. A sliding groove is located below the fixing block, and a slider is located within the groove. A compression spring is located on one side of the slider, and a fixing plate is located below the slider. One side of the fixing plate is connected to an arc-shaped clamp via a mounting block. This invention connects the output shaft of the motor to the milling cutter through the fixing device, making the milling cutter and fixing device detachably connected, facilitating the replacement of the milling cutter during use, and improving the ease of use of the device.

[0004] However, the above technical solution has the following shortcomings: the milling cutter is fixed by two locking bolts, which makes it difficult to ensure that the two locking bolts are completely symmetrical, resulting in the milling cutter and the drive shaft not being effectively aligned. The milling cutter is prone to vibration or displacement during rotation, which poses a significant safety hazard. Utility Model Content
