Description

Technical Field

[0001] The utility model relates to the technical field of a power tool holder, in particular to an inner circle groove milling power tool holder. Background Art

[0002] The turning and milling power tool holder is a power head on the turning and milling compound machine tool, which is installed on the power turret of the turning and milling compound machine tool. The driving motor in the power turret is used to drive the tool on the turning and milling power tool holder to rotate, thereby turning and milling the workpiece. After searching, an internal milling power tool holder (publication number: CN219986856U) is now disclosed. In this patent, the milling cutter chuck is installed at the free end of the main body support. However, the main body support structure in the milling cutter chuck area is large, which can be used for turning and milling workpieces with larger inner circles and inner holes, but cannot meet the needs of workpieces with smaller inner circles and inner holes. For this reason, we proposed an internal circle milling groove power tool holder. By vertically installing a smaller extension seat on one side of the fixed seat, it can be used for turning and milling of workpieces with smaller inner circles and inner holes.

[0017] The rotating rods are fixed in the extension seat, and the transmission gears and the driven gears are rotatably connected to the outside of the rotating rods through bearings.

[0018] Furthermore, the inner circle milling groove power tool holder also includes:

[0019] A tool is installed inside the clamping end of the nozzle.

[0020] Compared with the above-mentioned background technology, the internal circle milling power tool seat provided in the present application includes a fixed seat, an extension seat, a drive shaft, a nozzle, an output gear, an input gear, a transmission gear, a driven gear, a rotating rod and a tool. The free end of the extension seat is a cylindrical structure with a relatively thin size, which can be suitable for turning and milling of workpieces with smaller inner circles and inner holes. Furthermore, the gear ratio of the output gear, the transmission gear, multiple sets of driven gears and the input gear is 4:3:1:1, and the gear ratio enables the drive shaft and the drive nozzle to achieve high-speed rotation.

[0021] The utility model provides an internal milling groove power tool holder. Compared with the prior art, it has the following beneficial effects:

[0022] 1. The internal milling groove power tool holder is a tool holder that vertically installs an extension seat on one side of the fixed seat, and the nozzle is installed at the free end of the extension seat. Since the extension seat has a cylindrical structure and a thin size, it can be used for turning and milling of workpieces with smaller inner circles and inner holes.

[0023] 2. The internal milling power tool holder uses the transmission gear and multiple sets of driven gears to make the output gear drive the input gear to rotate, and then the nozzle and the tool rotate. Since the gear ratio of the output gear, transmission gear, multiple sets of driven gears and input gear is 4:3:1:1, the gear ratio enables the drive shaft and the drive nozzle to achieve high-speed rotation, increasing the turning and milling efficiency.
