[0031] The portable chamfering mechanism cutter head for auxiliary installation of pipelines of the utility model is described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] This embodiment discloses a portable chamfering mechanism cutter head for auxiliary installation of pipelines. Through the combined cutter head structure, the cutter head angle can be adjusted. The adjustment range is large, which can meet the chamfering requirements of various angles, improve construction efficiency, and ensure construction quality. Figure 1 , which mainly includes a protective slide 1 and a chamfering cutter head 2. The main body of the chamfering cutter head 2 is located inside the protective slide 1. A rectangular long hole 101 is opened on the side wall of the protective slide 1. Both ends of the chamfering cutter head 2 are hinged and slidably arranged at the rectangular long hole 101 of the protective slide 1. Through the above structure, the protective slide 1 can protect the chamfering cutter head 2, and at the same time, the chamfering cutter head 2 can be adjusted in the protective slide 1, as shown in the following content.

[0034] For installation and protection of chamfering cutter heads, see Figure 1 The protection slide 1 is a cylindrical structure with a closed top and an open bottom. A pin 111 is arranged in the rectangular long hole 101 of the protection slide 1. The pin is used to install the chamfering cutter head 2. At the same time, an annular groove for installation is opened on the outer wall of the bottom open part of the protection slide 1.

[0035] For adjustable angle chamfering heads, see Figure 1 , Figure 2 The chamfering cutter head 2 is a combined cutter head. It includes a cutter head A201, a cutter head B202 and a Y-shaped connector 203. The cutter heads A201 and B202 are hingedly connected at one end, and the other ends are slidably arranged at the rectangular long hole 101 of the protective slide 1. The bottom of the Y-shaped connector 203 is hingedly arranged at the hinge of the cutter head A201 and the cutter head B202. The cutter heads A and B are hingedly connected at one end to each other, and the other ends are slidably connected to the rectangular long hole 101 of the protective slide 1, thereby realizing the adjustable angle structure of the chamfering cutter head 1.

[0036] See also Figure 1 , Figure 2 The cutter head A201 and the cutter head B202 both include a cutter head body 211 and a blade portion 212. The blade portions 212 are symmetrically fixedly arranged on both sides of the cutter head body 211. The symmetrically arranged blade portions 212 can be used to cut the pipeline to achieve chamfering of the pipeline.

[0037] For details, see Figure 1 , Figure 3 , Figure 4 , the front end of the cutter head body 211 of the cutter head A201 is also provided with a clip-type hinge joint 213. The front end of the cutter head body 211 of the cutter head B202 is provided with a hinge hole 221. The cutter head body 211 of the cutter head A201 is hingedly connected with the hinge hole 221 at the front end of the cutter head body 211 of the cutter head B202 through the clip-type hinge joint 213 at its front end. At the same time, the spacing between the two clips of the clip-type hinge joint 213 at the end of the cutter head A201 is adapted to the thickness of the cutter head body 211. The angle adjustment between the cutter head A and the cutter head B is achieved through the hinged connection structure.

[0038] To ensure the cutting effect of cutter head A and cutter head B, refer to Figure 2 , Figure 3 The blade portion 212 is a blade structure with a curved surface on one side of the blade and a flat surface on the opposite side. The flat surface of the blade portion 212 is arranged to fit the side of the cutter head body 211. The curved surface on the blade side is more convenient for cutting and reduces cutting resistance. At the same time, the blade side is thicker than the traditional blade and has higher strength, which can effectively prevent the blade side from being deformed by force when cutting the pipe.

[0039] In order to realize that one end of the blade A and blade B is hinged, the other end slides and is hinged to connect the protective slide cylinder, see Figure 1 The ends of the blade heads A201 and B202 connected to the protection slide 1 are both provided with an oblong hole 214. A pin 111 is provided in the rectangular oblong hole 101 of the protection slide 1. The blade heads A201 and B202 slide through the oblong holes 214 provided thereon and are hingedly connected to the pin 111 in the rectangular oblong hole 101.

[0040] See also Figure 1 , Figure 5 The Y-shaped connector 203 includes a connecting ring 231, a connecting rib plate 232 and a hinged portion 233. The hinged portion 233 is fixedly connected to the connecting ring 231 through the connecting rib plate 232. The lower end of the hinged portion 233 is hingedly connected to the hinge of the cutter head A201 and the cutter head B202.

[0041] To ensure the connection strength between the connecting ring and the hinge. Figure 1 , Figure 5 There are at least four connecting ribs 232 , which are distributed in an array and fixedly disposed on the upper section of the hinge portion 233 .

[0042] The working principle of the portable chamfering mechanism cutter head for auxiliary pipeline installation of the utility model:

[0043] The device can adjust the chamfering angle through the hinged structure of the cutter head A and the cutter head B, and when the device chamfers the pipe, the arc surface on the blade side is more convenient for cutting, reducing the cutting resistance and making the chamfering efficiency higher.
