[0001] This application relates to the field of clamping technology, and more specifically, to a clamping device for bonding irregularly shaped parts. Background Technology

[0002] CNC machining uses computer programs to control the movement of machine tools, enabling precise control of tool paths and cutting parameters. In the process of machining 3D printed parts using CNC, two common clamping methods are mechanical clamping and adhesive clamping. Mechanical clamping uses screws, pressure plates, etc., for clamping, while adhesive clamping uses AB glue, hot melt glue, 502 glue, etc., for bonding.

[0003] However, both of the above clamping methods have drawbacks:

[0004] 1. Mechanical clamping is not suitable for workpieces with complex shapes or a certain degree of deformation;

[0005] 2. Adhesive-fastened clamping has problems such as long adhesive curing time, low clamping efficiency, and easy loosening. Summary of the Invention

[0006] The purpose of this application is to provide a clamping device for bonding irregularly shaped parts, which can solve the technical problem that the existing clamping methods have the above-mentioned drawbacks in the process of processing 3D printed parts using CNC.

[0007] This application provides an irregular part bonding and clamping device, including a base, on which multiple adhesive fastening components are provided.

The outer surface of the hollow cylinder is provided with a first thread adapted to the fastening nut. The hollow cylinder is threadedly connected to the fastening nut. The light guide head is provided with a second thread adapted to the connecting nut. The light guide head is threadedly connected to the connecting nut. The end of the light guide hose is inserted into the hollow cylinder and is interference-fitted with the hollow cylinder.

[0009] Furthermore, the base is provided with multiple support components, each including a support column and a support nut. The support nut is fixed to the base, and the lower end of the support column is provided with a third thread that is adapted to the support nut. The support column and the support nut are threadedly connected.

[0010] Furthermore, the base is provided with several positioning posts, which are inserted into the base.

[0011] Furthermore, the base is provided with a support protrusion, which is detachably connected to the base.

[0012] Furthermore, the support protrusion is provided with a mounting hole, the base is provided with a mounting threaded hole, a mounting bolt is provided in the mounting hole, and the end of the mounting bolt passes through the mounting hole and is threadedly connected to the mounting threaded hole.

[0030] like Figure 1-4 As shown, this application provides a device for bonding and clamping irregularly shaped parts, including a base 1. Multiple adhesive fastening components 2 are provided on the base 1. Each adhesive fastening component 2 includes a light guide head 21, a connector 22, a fastening nut 23, and a light guide hose. The fastening nut 23 is fixed to the base 1. The light guide head 21 is connected to the fastening nut 23 via the connector 22. The base 1 has a light guide hole 11 communicating with the fastening nut 23. One end of the light guide hose is inserted into the light guide hole 11 and connected to the connector 22. The multiple adhesive fastening components 2 are used to fasten the 3D printed parts. Clamping: Specifically, adhesive (UV adhesive or photosensitive resin) is applied to the light guide head 21 of the adhesive fastening assembly 2. Then, the 3D printed part to be processed is pressed against the light guide head 21. It is connected to an external ultraviolet emission source through a light guide hose. The ultraviolet light enters the light guide head 21 through the light guide hose and acts on the adhesive, accelerating the curing of the adhesive. Compared with the existing technology, it can adapt to the clamping of irregularly shaped 3D printed parts and effectively shorten the clamping efficiency. The strength of the adhesive cured by ultraviolet light is greatly improved, avoiding the loosening of the 3D printed parts during processing.

[0031] like Figure 4As shown, the connector 22 includes a hollow cylinder 221 and a connecting nut 222 fixed to the upper end of the hollow cylinder 221. The outer surface of the hollow cylinder 221 is provided with a first thread that matches the fastening nut 23. The hollow cylinder 221 is threadedly connected to the fastening nut 23. The light guide head 21 is provided with a second thread that matches the connecting nut 222. The light guide head 21 is threadedly connected to the connecting nut 222. The end of the light guide hose is inserted into the hollow cylinder 221 and is interference-fitted with the hollow cylinder 221. Through this connection method, the light guide head 21, the connector 22 and the fastening nut 23 are tightly combined together to form a stable overall structure. This allows the device to withstand various external forces without being easily damaged when facing complex irregular part clamping tasks. In this embodiment, the light guide head 21 is made of a high-transparency material, such as acrylic, which has a high transmittance of ultraviolet rays and can effectively conduct ultraviolet rays from the light source to the part that needs to be irradiated, so that the adhesive can cure quickly.

[0032] like Figure 1 As shown, the base 1 is provided with multiple support components 3. The support component 3 includes a support column 31 and a support nut 32. The support nut 32 is fixed on the base 1. The lower end of the support column 31 is provided with a third thread that matches the support nut 32. The support column 31 and the support nut 32 are threadedly connected. During the bonding and clamping process of irregular parts, different irregular parts may have different shape and size requirements. By selecting a support column 31 of appropriate length, the clamping requirements of various irregular parts can be flexibly adapted. For example, for some 3D printed irregular parts with complex curved surfaces, it may be necessary to provide support at different heights in different positions to ensure that the irregular parts can be kept in a suitable clamping position, which is convenient for the application and curing of adhesive. The threaded connection means that the height of the support column 31 can be precisely adjusted by rotating the support column 31, thereby improving the stability of the support.

[0033] like Figure 1 As shown, the base 1 is provided with several positioning posts 4. The positioning posts 4 are inserted into the base 1. The positioning posts 4 provide a clear positional reference for the placement of irregular 3D printed parts. During the clamping process of irregular 3D printed parts, when the irregular part is placed on the base 1, the positioning posts 4 can help determine the initial position of the irregular 3D printed parts.

[0034] like Figure 1-3 As shown, the base 1 is provided with a support protrusion 5, which is detachably connected to the base 1. The support protrusion 5 can be flexibly selected to adjust the support comfort according to the specific shape and size requirements of the 3D printed part. For example, for some irregular parts with large thickness or special height requirements, installing the support protrusion 5 can provide additional height support to ensure that the irregular part is in the right position during clamping.

[0035] like Figure 1 and Figure 2 As shown, the support protrusion 5 has a mounting hole 51, and the base 1 has a mounting threaded hole. A mounting bolt 6 is installed in the mounting hole 51, and the end of the mounting bolt 6 passes through the mounting hole 51 and is threaded into the mounting threaded hole. This connection method using the mounting bolt 6 is simple and easy to understand. When installing the support protrusion 5, simply pass the mounting bolt 6 through the mounting hole 51 and screw it into the mounting threaded hole to complete the installation. Operators do not need complicated tools or professional skills to quickly install the support protrusion 5 onto the base 1. This helps to improve the assembly efficiency of the clamping device, especially in the case of mass production or frequent replacement of the support protrusion 5, which can save a lot of time and labor costs. When it is necessary to disassemble the support protrusion 5, such as for maintenance, replacement or adjustment of the position of the support protrusion 5, simply unscrew the mounting bolt 6 to easily remove the support protrusion 5 from the base 1.

[0036] like Figure 1 As shown, a support adjustment assembly 7 is provided on the base 1. The support adjustment assembly 7 includes a guide post 71, a support member 72, and a locking bolt 73. A guide groove 8 is provided on the base 1. One end of the guide post 71 is slidably connected to the guide groove 8, and the other end of the guide post 71 is fixedly connected to the support member 72. A groove-shaped guide hole 9 is provided on the support member 72. A locking threaded hole adapted to the locking bolt 73 is provided in the guide groove 8 on the base 1. The end of the locking bolt 73 passes through the groove-shaped guide hole 9 and is threadedly connected to the locking threaded hole. In this embodiment, the sliding connection between the guide post 71 and the guide groove 8 not only realizes the adjustment function, but also provides a stable support path for the support member 72. After adjusting the position of the support member 72, tightening the locking bolt 73 can firmly fix the support member 72 in the required position. This fastening method can resist external force interference that may occur during the clamping process, such as vibration and collision, and ensure that the support member 72 will not easily shift, thereby providing continuous and stable support for the 3D printed part.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
