Description
Technical Field
The utility model relates to the technical field of material processing, in particular to an arc cutting port assistor.
Background
At present, in the construction of bamboo structure building construction, the problem that the connecting node of the bamboo structure always needs to cut an arc port appears. In actual installation, because of design and installation direction, it is quite often the case that the cut-out of each node is different. At present, the line drawing and the arc cutting are carried out by relying on experience of a processing worker, but the line drawing and the arc cutting are carried out by purely manual operation, and have larger errors. In addition, there is an arcuate mouth cutting rotary tool holder as in application No. 2016106020116 and an adjustable arcuate cutting device as in application No. 202210518548.X, which are extremely complex and inconvenient to carry and use. Therefore, there is a need for a portable and easy-to-use arc cutting port assist device.

In order to solve the technical problems, the utility model provides the arc-cutting port auxiliary device, which is characterized in that a certain radian die is formed by butt-jointing arc-shaped contact surfaces of round tube-shaped materials and manually pressing the position of an auxiliary rod, one end of the round tube material to be cut is plugged into a central hole of the arc-shaped auxiliary device and exceeds the auxiliary rod with the formed arc port, the arc-cutting line is drawn along the position of the auxiliary rod with the formed arc port by a pen, the drawn round tube material is finally extracted, the comparison cutting is completed, and all the auxiliary rods are required to be restored and aligned when the round tube material is reused.
The utility model adopts the following technical scheme:
a slit aid comprising: the auxiliary device body is of a circular tube-shaped rubber structure, the middle part of the auxiliary device body is provided with a through hole, and the circular tube-shaped structure is provided with a plurality of mounting holes; the auxiliary rods are positioned in the mounting holes of the auxiliary body and are attached to the inner surfaces of the mounting holes.
Preferably, the auxiliary rod is a stainless steel round rod.
Preferably, the mounting hole is located at the edge of the body of the aid and tangential to the central through hole.
Preferably, the auxiliary device body is provided with an alignment line.
Preferably, the auxiliary body includes a mounting portion in the middle and reinforcing portions at both ends of the mounting portion.
Preferably, the reinforcement portion has a regular octagonal structure.
Compared with the prior art, the utility model has the following advantages: the utility model provides an arc cutting port auxiliary device, which is characterized in that a certain radian is formed by manually pressing the position of an auxiliary rod, a corresponding arc is manually drawn on a material needing an arc cutting port, and an arc opening is carried out by an auxiliary circular tubular structure.

Detailed Description
In order to facilitate understanding of the technical scheme of the present utility model, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 1-2, a notch assist apparatus comprising:
the auxiliary device body 1 is of a circular tube-shaped rubber structure, the middle part of the auxiliary device body is provided with a through hole 12, and the circular tube-shaped structure is provided with a plurality of mounting holes 11;
the auxiliary rods 2 are positioned in the mounting holes 11 of the auxiliary body 1 and are attached to the inner surfaces of the mounting holes 11.
Wherein, the auxiliary rod 2 is a stainless steel round rod.
In this embodiment, the mounting hole 11 is located at the edge of the helper body 1 and tangential to the middle through hole or the mounting hole 11 is located close to 1mm from the middle through hole.
For easy alignment, the auxiliary body 1 is provided with an alignment line 13.
In fig. 2, a part of the auxiliary rod 2 is omitted for convenience of illustration.
As shown in fig. 3 to 8, when the utility model is used (taking a hollow steel pipe as an example), a section of central line is drawn on a first steel pipe, an arc cutting port auxiliary device is abutted against the first steel pipe, an alignment line 13 is aligned with the central line, auxiliary rods 2 are pressed downwards from the upper end, a plurality of auxiliary rods 2 move downwards and are abutted against the surface of the first steel pipe, the lower ends of all the auxiliary rods 2 form an arc structure which is jointed with the surface of the first steel pipe, a second steel pipe to be cut and connected with the first steel pipe is placed into a through hole 12 from the middle area of the plurality of auxiliary rods 2, an arc port shape is drawn on the surface of the second steel pipe according to the arc structure formed at the lower end of the auxiliary rods 2, and the arc port structure is jointed with the surface of the first steel pipe after the second steel pipe is cut and welded and fixed.
In addition, the arc cutting port auxiliary device can be used for circular tubes such as bamboo, cylindrical plastic and the like and cylindrical materials.
The auxiliary rod 2 is tightly attached to the mounting hole 11, that is, the auxiliary rod 2 cannot slide due to dead weight, and must be moved by external force, for example, manually pressed, so that the arc structure formed by attaching the lower end of the auxiliary rod 2 to the surface of the first steel pipe can be prevented from being changed due to the dead weight of the auxiliary rod 2.
As a preferred manner, the auxiliary body 1 includes a mounting portion 14 in the middle and reinforcing portions 15 at both ends of the mounting portion 14, and the reinforcing portions 15 are formed by extending the mounting portion 14 outwards, so as to improve the overall structural strength.
In a preferred embodiment, the reinforcement 15 has a regular octagonal structure, and can be placed horizontally when not in use, so that the reinforcement is not likely to fall off.
For practical use, a plurality of arc cutting aids of different diameters may be made so as to be suitable for arc cutting procedures of round tubular structures of various diameters.
The foregoing is merely a preferred embodiment of the present utility model, and the scope of the utility model is defined by the claims, and those skilled in the art should also consider the scope of the present utility model without departing from the spirit and scope of the utility model.
