[0036] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0037] An embodiment of the utility model discloses a gear rough milling cutter with adjustable module.

[0038] According to the attached Figures 1-5 shown, it includes:

[0039] The first unit includes a first ring body 1 and a plurality of groups of rough milling cutter bodies 11 arranged on one side of the first ring body 1. The second unit includes a second ring body 2 and a plurality of groups of pointed milling cutters 21 arranged on one side of the second ring body 2. The inner wall of the second ring body 2 is connected to the outer wall of the first ring body 1. A central hole 12 is opened on one side of the first ring body 1. Screws 3 for installing the rough milling cutter bodies 11 and the pointed milling cutters 21 are respectively rotatably connected to the outer walls of the first ring body 1 and the second ring body 2. When the first unit is used alone, the gear rough milling cutter processes a workpiece with one module through the rough milling cutter bodies 11 arranged thereon. After the first unit and the second unit are combined, another set of gear rough milling cutters is formed. As shown in the attached Figure 1 shown state, at this time, the overall diameter of another set of gear rough milling cutters changes, so that the rough milling cutter bodies 11 and the pointed milling cutters 21 can process a workpiece with another module.

[0040] A first connecting mechanism 4 is arranged between the first ring body 1 and the second ring body 2. By arranging the first connecting mechanism 4, another set of ring bodies can be arranged on the basis of the first ring body 1, so as to change the overall diameter of the gear rough milling cutter, and further adjust the module of the gear rough milling cutter, so as to meet the processing requirements of workpieces with different modules. The first connecting mechanism 4 includes a ring frame 41. The ring frame 41 is fixedly connected to the outer wall of the first ring body 1. A clamping block 43 is fixedly arranged on one side of the second ring body 2, and the clamping block 43 is clamped inside the ring frame 41. A first screw rod 44 is rotatably arranged on the outer wall of the ring frame 41. The ring frame 41 and the clamping block 43 are locked by the first screw rod 44. A first clamping groove 42 adapted to the clamping block 43 is opened on one side of the ring frame 41. The clamping block 43 is clamped inside the first clamping groove 42. One end of the first screw rod 44 is rotatably arranged inside the first clamping groove 42. A first groove body 45 is opened on one side of the first clamping groove 42 for hiding the first screw rod 44.

[0041] The outer wall of the second annular body 2 is provided with a second connecting mechanism 5. Through the second connecting mechanism 5, the second annular body 2 and another group of annular bodies are assembled and installed. By means of the provided second connecting mechanism 5, another group of annular bodies can be arranged on the basis of the first annular body 1 and the second annular body 2, thereby further changing the overall diameter of the gear rough milling cutter, and then regulating the module of the gear rough milling cutter so as to meet the processing requirements of workpieces with different modules. The second connecting mechanism 5 includes a connecting ring 51. The connecting ring 51 is fixedly arranged on the outer wall of the second annular body 2. A second clamping groove 52 is opened on one side of the second annular body 2. A second screw 53 is rotatably arranged on the outer wall of the connecting ring 51. The second annular body 2 and another group of annular bodies are fixed by the second screw 53. One end of the second screw 53 is rotatably arranged inside the second clamping groove 52. A second groove body 54 for assisting in hiding the second screw 53 is opened on one side of the second clamping groove 52.

[0042] Based on the above first connecting mechanism 4 and second connecting mechanism 5, for another group of annular bodies, a set of connecting mechanisms can also be arranged on their outer walls, so that by combining or disassembling multiple groups of annular bodies, the regulation of the overall diameter of the wheel rough milling cutter is realized, and then the module of the wheel rough milling cutter is regulated according to the processing requirements of workpieces of different models.
