[0024] Combined with reference Figure 1-Figure 4The utility model provides a milling cutter seat structure, including a tool seat 1, which can be installed on a machine tool. A slot 2 is provided on the tool seat 1, and an assembly seat 3 is detachably connected in the slot 2. The assembly seat 3 can be detachably connected to the slot 2 by bolts, so that the assembly seat 3 and the structure on the assembly seat 3 can be conveniently installed. A swing arm 4 is rotatably connected to the assembly seat 3 through a rotating shaft, and a worm gear 5 is fixedly connected to the rotating shaft. The worm gear 5 is arranged at an upper position of the swing arm 4, and a worm 6 is drivingly connected to the worm gear 5. The worm gear 6 is mounted in the slot 2, and the worm gear 6 drives the worm gear 5 to meet In order to achieve the effect of self-locking angle adjustment, a driving structure 9 for driving the worm 6 to rotate is arranged in the slot 2, a sliding support structure 10 is detachably connected to one side of the tool seat 1, one end of the swing arm 4 is arranged at the sliding part of the sliding support structure 10, a tool box 11 is arranged at the sliding part of the sliding support structure 10, and a connected square tool groove 12 and a circular tool groove 121 are arranged at one end of the tool box 11, the square tool groove 12 and the circular tool groove 121 can adapt to the installation requirements of the milling cutter handle in rectangular and cylindrical shapes, and the parallel combination of the square tool groove 12 and the circular tool groove 121 can improve the utilization rate of the installation space.

[0025] The left support 7 and the right support 8 are disassembled and connected in the slot 2, and the worm 6 is rotatably connected to the left support 7 and the right support 8. The left support 7 and the right support 8 can be used for supporting and rotating the worm 6, and the left support 7 and the right support 8 can be disassembled in the slot 2 by screws, which can meet the convenience of assembly on the tool seat 1.

[0026] The driving structure 9 includes a shaft 91 rotatably connected to the left support 7, a bevel gear 1 92 fixedly connected to the shaft 91, a bevel gear 2 93 meshingly connected to the bevel gear 1 92 and a transmission cap 94 fixedly connected to the bevel gear 1 92. The bevel gear 2 93 is fixedly connected to one end of the worm 6. The transmission cap 94 is provided with an inner angle groove, which can be driven to rotate by a rotating tool. Since the driving structure 9 is arranged on the left support 7 and the left support 7 can be easily disassembled, the driving structure 9 can be disassembled at the same time.

[0027] Specifically, by driving the transmission cap 94 to rotate, the worm 6 can be driven to rotate under the action of the meshing of bevel gear 1 92 and bevel gear 2 93, and the worm wheel 5 can drive the swing arm 4 to rotate around the connection of the rotating shaft. The swing arm 4 drives the tool box 11 to move the angle through the sliding support structure 10, so that the milling cutter set on the tool box 11 can adjust the angle to meet the processing requirements of different angles of the workpiece. Because the worm 6 drives the worm wheel 5 with self-locking properties, the stability of the angle hovering can be improved.

[0028] A support plate 14 is fixedly connected to the tool seat 1, and an angle digital display 15 for detecting the rotation angle of the worm gear 5 is arranged on the support plate 14.

The slide 102 can slide in the arc-shaped slide groove along with the movement of the swing arm 4, so that the slide 102 can drive the tool box 11 to adjust the angle. When the milling cutter set on the tool box 11 generates force during processing, the force can be respectively applied to the arc-shaped reinforcement plate 101 through the slide 102, thereby reducing the force on the swing arm 4 and improving the structural strength and stability of the milling cutter processing.

[0031] The knife box 11 is provided with a first mounting hole 13 and a second mounting hole 131 horizontally and vertically. The first mounting hole 13 and the second mounting hole 131 are both connected to the square knife groove 12. By inserting the handle of the milling cutter into the square knife groove 12 or the circular knife groove 121, and utilizing the mounting holes configured on the handle, the first mounting hole 13 and the second mounting hole 131 can be inserted into the square knife groove 12 by bolts to be fastened with the mounting holes on the handle of the milling cutter.
