[0006] Several component rotating wheels are connected to the handwheel and the component rotating wheels by a driving component.

[0007] A part fixing mechanism includes a part fixing end fixedly connected to a part rotating wheel and a pin disposed inside the base. The part fixing end and the pin are disposed opposite to each other, forming a space for placing the part.

[0008] A cutting tool is provided on one side relative to the fixed end of the part, and a contact platform is provided below the cutting tool.

[0009] Furthermore, the base is provided with three sets of part fixing mechanisms from top to bottom.

[0032] Several parts rotating wheels 3, handwheel 2 and parts rotating wheels 3 are connected by a driving component. In this embodiment, there are three sets of parts rotating wheels 3 for connecting the fixed end 301 of the parts and two sets of driven parts rotating wheels 3 from top to bottom. In this embodiment, the parts rotating wheels 3 and handwheel 2 are located on the same side of the base 1.

[0033] The part fixing mechanism includes a part fixing end 301 fixedly connected to the part rotating wheel 3 and a pin 4 disposed inside the base 1. The part fixing end 301 and the pin 4 are disposed opposite to each other, forming a space for placing the part. In this embodiment, the pin 4 is a screw. The base 1 has a screw hole on one side opposite to the part fixing end 301. The pin 4 is screwed into the screw hole and its end is a pointed tip to abut against the part and allow the part to rotate on it. A fixing groove is formed on the part fixing end 301. The end of the part away from the pin 4 is locked in the fixing groove and then further fixed by thread fixing to complete the fixed installation of the part.

[0034] The cutting tool 5 is located on one side relative to the fixed end 301 of the part, and a contact platform 6 is provided below the cutting tool 5.

[0035] In this embodiment, the cutting tool 5 is a comb cutter. In use, the base 1 is placed on a table, and the comb cutter is installed on the table. A drive motor for driving the comb cutter to rotate is connected below the comb cutter. Specifically, the comb cutter is sleeved on the output end of the drive motor and is correspondingly set on one side of the base 1. The connection method between the comb cutter and the drive motor is a conventional technique in the art and will not be described in detail here. In addition, the base 1 can be moved manually to make it abut against the cutting tool 5 and move along the cutting direction of the cutting tool 5 to cut the workpiece 200 in the length direction. The contact platform 6 is fixed below the cutting tool 5 and contacts the table. The drive motor extends upward through the through hole on the contact platform 6, and the cutting tool 5 is sleeved on it.

[0036] like Figure 2-5As shown: The base 1 is provided with three sets of part fixing mechanisms from top to bottom. The part fixing mechanisms include two sets of first part fixing mechanisms for fixing the part to be processed 200 and a second part fixing mechanism for fixing the sample 100.

[0038] In this embodiment, the external post 103 is integrally formed on one side of the first base 101, and the plug post 104 is integrally formed on one side of the second base 102. When it is necessary to adjust the distance between the first base 101 and the second base 102, the first base 101 or the second base 102 can be pulled outward after the fixing bolt 105 is loosened. The external post 103 and the plug post 104 are provided with a number of positioning holes arranged in sequence. After adjusting to the required position, the fixing bolt 105 can be inserted into the corresponding positioning hole to complete the limiting.

[0039] Through the above-mentioned length extension design, a first seat 101 and a second seat 102 are set. The first seat 101 and the second seat 102 can be fixed to each other by the cooperation of the external post 103 and the plug post 104, and can be limited by the fixing bolt 105. The above design allows the first seat 101 and the second seat 102 to move relative to each other, thereby adjusting the distance between them to meet the processing of parts of different lengths.

[0040] like Figure 2-4As shown: Several through holes are provided on one side of the first base 101, and a rotating shaft 106 is rotatably installed in each through hole. The part fixing end 301 is fixed to one end of the rotating shaft 106 near the second base 102, and the other end of the rotating shaft 106 is fixed to the part rotating wheel 3.

[0041] like Figure 2 As shown: The driving component is a belt 7. The handwheel 2 is equipped with a handwheel drive wheel for connecting the belt 7.

[0043] like Figure 1-3 As shown: A part rotation angle adjustment disc position fixing mechanism is provided on one side of the base 1. The part rotation angle adjustment disc position fixing mechanism includes an adjustment plate 9. One end of the adjustment plate 9 is fixed to the base 1 by a bolt. A plug-in component is provided on the side of the adjustment plate 9 away from the bolt. An angle adjustment disc 10 is provided on the handwheel 2. The angle adjustment disc 10 is provided with a slot for the plug-in component to be inserted.

[0044] The working principle and beneficial effects of this utility model are as follows:

[0045] A base 1 is provided, and a handwheel 2 and several part rotating wheels 3 are rotatably mounted on one side of the base 1. One end of each part rotating wheel 3 extends to the inside of the base 1 via a rotating shaft 106 and has a part fixing end 301 on it. A pin 4 is provided on the side of the base 1 opposite to the part fixing end 301. The several part rotating wheels 3 and the handwheel 2 are connected by a belt 7. By rotating the handwheel 2, all the part rotating wheels 3 can be driven to rotate synchronously, thereby causing the part fixing end 301 fixed on it to rotate. In addition, a cutting tool 5 is provided on one side of the base 1. The cutting tool 5 can move left and right along the side of the base 1 with the part fixing end 301. In use, a part sample 100 is first installed between the lowest part fixing end 301 and the pin 4, and the contact platform 6 below the cutting tool 5 abuts against the outer surface of the part sample 100. Then, the part to be processed is fixed on the part fixing platform above the part sample 100. The mechanism is positioned so that it corresponds to the cutting edge of the cutting tool 5. Then, the handwheel 2 is turned, and the cutting tool 5 is started to rotate. As the handwheel 2 rotates, the belt 7 drives all the part rotating wheels 3 to rotate, thereby causing the part fixed end 301 fixed on the part rotating wheel 3 to rotate synchronously. After the part rotating wheel 3 rotates, the part sample 100 and the part to be processed, which are fixed between the part rotating wheel 3 and the ejector pin 4, will also rotate. At this time, since the cutting tool 5 is fixed on one side of the part to be processed 200, the cutting tool 5 will cut the part to be processed 200. At the same time, the base 1, which is movable and fixed with the part sample 100 and the part to be processed 200, allows the part sample 100 to move along the contact platform 6 to capture the shape of the part sample 100. The cutting tool 5 cuts the part to be processed 200 into the same trajectory shape as the part sample 100, thereby completing the contour processing of the irregular part.

[0046] Therefore, the above-mentioned product has the following beneficial effects: 1. Small size and low cost; 2. It can perform contour machining of irregularly shaped parts with multiple curves and the machining of lines on irregularly shaped parts, and the machined parts have high precision; 3. Low technical requirements for employees, simple product structure, and easy operation; 4. Reduced tool change frequency; 5. This device is operated manually throughout the entire process, without direct contact with the cutting tool, thus improving production safety. It solves the technical problems of high operator skill requirements, low precision of machined parts, need for multiple tool changes, low production efficiency, and high safety risks in the current machining of irregularly shaped parts.

[0047] Furthermore, the principle of this utility model can be used for simple copying equipment. Currently, most copying equipment on the market requires the use of CNC equipment, which requires programming. However, by utilizing the design principle of this product, programming can be eliminated.
