Description

Technical Field

[0001] This application relates to the field of machine tool processing technology, specifically to positioning devices and processing production lines. Background Technology

[0002] Before machining a workpiece using a CNC machine tool, the workpiece needs to be positioned. In related technologies, a positioning groove is provided on the machining platform. The workpiece is installed in the positioning groove and then fixed. The machining tool needs to machine the periphery of the workpiece, but the edge of the workpiece cannot be accommodated between the edge and the inner wall of the positioning groove. Therefore, the edge of the workpiece needs to be cut to create a gap between the edge and the inner wall of the positioning groove. The machining tool moves within this gap to machine the workpiece.

[0003] After the workpiece is positioned in the positioning groove, its edges need to be cut to ensure that the machining tool can be located between the workpiece and the groove wall, which facilitates the machining of the workpiece's edges. This machining method increases the machining depth of the workpiece, resulting in waste of the workpiece. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Before machining a workpiece using a CNC machine tool, the workpiece needs to be positioned. In related technologies, a positioning groove is provided on the machining platform. The workpiece is installed in the positioning groove and then fixed. The machining tool needs to machine the periphery of the workpiece, but the edge of the workpiece cannot be accommodated between the edge and the inner wall of the positioning groove. Therefore, the edge of the workpiece needs to be cut to create a gap between the edge and the inner wall of the positioning groove. The machining tool moves within this gap to machine the workpiece.

[0022] After the workpiece is positioned in the positioning groove, its edges need to be cut to ensure that the machining tool can be located between the workpiece and the groove wall, facilitating the machining of the workpiece's edges. This machining method increases the machining depth of the workpiece, resulting in waste of the workpiece. To solve or improve the problem of serious material waste during the machining of the workpiece, this application provides a positioning device and a machining production line.

[0026] After multiple telescopic parts position the workpiece, the vacuum mechanism 6 fixes the workpiece in the processing area 2. During the processing of the edge of the workpiece by the tool, there is no need to cut the workpiece separately to form a tool travel path, thus reducing the waste of material from the workpiece.

[0027] In some embodiments, the workpiece to be processed is a plate-like structure.

[0040] In this embodiment, the positioning surface 11 corresponds to the edge of the processing area 2, which can fit more closely to the workpiece to be processed, increase the contact area with the workpiece to be processed, and improve the positioning effect.

[0041] In one embodiment, the system further includes a base 12 and a plurality of support columns 13, with one end of the plurality of support columns 13 connected to the base 12 and the other end connected to the workbench 1.

[0042] In this embodiment, the base 12 and the worktable 1 are connected by multiple support columns 13, which provides good stability. A gap is formed between the base 12 and the worktable 1, and the telescopic mechanism 5 is located within the gap, saving external space.

[0043] In some embodiments, the workbench 1 is provided with a plurality of first connection holes 16, and one end of a plurality of support columns 13 is provided with a second connection hole corresponding to the first connection hole 16.

[0058] The telescopic mechanism 5 uses a cylinder. First, the cylinder is activated, and its telescopic rod extends, driving the positioning pin 10 through the through hole 3. The positioning pin 10 is located on the top surface of the worktable 1. Multiple positioning pins 10 are arranged along the edge of the processing area 2 to position the workpiece within the processing area 2. Each positioning pin 10 has a positioning surface 11 on its corresponding side in the processing area 2. The positioning surface 11 corresponds to the edge of the processing area 2, allowing for a closer fit with the workpiece, increasing the contact area and improving the positioning effect. After the positioning pin 10 is in position, the workpiece is placed in the processing area 2, with its side abutting against the positioning surface 11 of the positioning pin 10, thus positioning the workpiece within the processing area 2.

[0059] The vacuum pump is started, and its suction port is connected to the adsorption port 4 through pipe 7. The adsorption port 4 is connected to multiple first grooves 8 and multiple second grooves 9, forming a mesh-like suction cup that firmly adsorbs the workpiece to be processed onto the processing area 2.
