[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. By using a pre-installed platform to complete the workpiece clamping outside the machine tool, and then installing the pre-installed platform on the base plate of the machine table, the time for clamping the workpiece on the machine tool is reduced;

[0011] 2. The positioning accuracy of the pre-installed platform can be ensured by coordinating the pull nails, the zero-point positioning chuck, and the height limit of the pre-installed platform with the equal height block, so that processing can be carried out directly, which greatly improves the processing efficiency of the machine tool;

[0012] 3. The side of the pre-installation platform is limited by the positioning column, which makes it easier to align the pull nail with the zero-point positioning chuck and improve the installation efficiency of the pre-installation platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0020] like Figure 1-Figure 5 As shown, the utility model is a zero-point tooling device for external clamping, comprising at least one basic base plate 2 and a pre-installed platform 8, wherein the top surface of any basic base plate 2 is respectively provided with an equal height block 3 and a zero-point positioning chuck 4, and the height of the equal height block 3 is greater than or equal to the height of the zero-point positioning chuck 4; a pull pin 9 is provided in the lower side surface of the pre-installed platform 8 for cooperating with the zero-point positioning chuck 4; a positioning column 7 is provided in the top surface or side surface of the basic base plate 2, and the positioning column 7 is used to limit the side of the pre-installed platform 8.

[0021] Furthermore, when the number of the basic base plates 2 is more than 2, they are distributed in an array.

[0022] Furthermore, a groove 10 is provided on the side of the pre-installation platform 8 to cooperate with the positioning column 7 .

[0023] Furthermore, the contour blocks 3 and the zero-point positioning chucks 4 are distributed in an array on the base plate 2 .

[0024] Furthermore, a dust cover 6 is provided above the base plate 2 , and the tops of the contour blocks 3 and the zero-point positioning chuck 4 are exposed from the dust cover 6 .

[0025] Furthermore, a support column 5 is provided above the base plate 2 , and a dust cover 6 is installed above the support column 5 .

[0026] When the present invention is used, the workpiece is first clamped on the pre-installed platform 8 outside the machine tool, and then the pre-installed platform 8 is moved to the top of the base plate 2. The positioning column 7 roughly positions the side of the pre-installed platform 8, so that the pull pin 9 below the pre-installed platform 8 is aligned with the zero-point positioning chuck 4. The equal height block 3 limits the height of the pre-installed platform 8 and plays a supporting role. The pull pin 9 is inserted into the zero-point positioning chuck 4 and locked, and then the workpiece can be processed.

[0027] The base plate 2 is mounted on the machine tool's platform 1. If there are two or more base plates 2, they are arranged in an array above the platform 1, providing even support beneath the pre-assembly platform 8. This ensures the support and positioning of large pre-assembly platforms 8, facilitating the machining of larger workpieces. A positioning fixture can be installed on the pre-assembly platform 8 as needed to clamp the workpiece. The matching structure of the pull pin 9 and the zero-point positioning chuck 4 is conventional, and can adopt the pull pin and zero-point positioning device structure disclosed in Publication No. CN221474245U.

[0028] When installing the pre-installed platform 8 , the groove 10 is aligned with the positioning column 7 , so as to facilitate the quick installation of the pre-installed platform 8 and further accurately limit the position of the pre-installed platform 8 .

[0029] A dust cover 6 can be screwed onto the support columns 5 above the base plate 2, protecting the base plate 2 and enhancing the overall aesthetics of the structure. Multiple support columns 5 can be arranged in a row to support the dust cover 6 and prevent it from collapsing. If a pneumatic zero-point positioning chuck 4 is used, the air pipe can be placed within the dust cover 6 to provide protection.
