[0003] Currently, most companies produce a wide variety of product types and models. Because products need to be frequently changed according to customer order requirements and product batch models, the CNC machining center needs to dismantle the existing workpiece tooling and replace it with new product tooling every time it changes. Since each product tooling is different, the product needs to be re-metered, aligned, centered, tooled, and a new coordinate system needs to be established.

[0004] Sometimes, due to insufficient number of product blanks or a small number of missing orders, it is necessary to switch back and forth between several products. When switching between different products, it is necessary to re-table, align, center, set tools and establish a new coordinate system, which makes each change of work very inefficient and complicated. There are also debugging dimensional errors, which lead to product dimensional deviations or scrapping. Utility Model Content

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model embodiment discloses a universal tooling base plate for CNC processing.

[0024] According to the attached Figure 1-5 As shown, it includes a universal tooling base plate body 1, the bottom of which is fixedly connected to the machine tool workbench 2, and the top of the universal tooling base plate body 1 is connected to the product tooling 6. A plurality of pin holes 3 are opened on the universal tooling base plate body 1, and two positioning pins 4 are provided. The two positioning pins 4 and the plurality of pin holes 3 are used to fix the connection between the product tooling 6 and the universal tooling base plate body 1.

[0025] The universal tooling base plate body 1 is fixed to the machine tool workbench 2. When the product is changed, only the old product tooling 6 needs to be removed. Two positioning holes 7 are provided on the product tooling 6, and the positioning pins 4 are inserted between the corresponding positioning holes 7 and the pin holes 3.

[0026] Place the new product tooling 6 at a suitable position, align the positioning hole 7 opened on the new product tooling 6 with the pin hole 3 at a suitable position, and insert the positioning pin 4;

[0027] It should be emphasized that the two locating pins 4 are spirally connected with bolts 5 at their geometric center positions, and a rotation groove 501 is provided on the top of the bolt 5. The rotation groove 501 on the top of the bolt 5 at the geometric center position of the locating pin 4 is rotated by an external device, so that the extrusion block 401 at the bottom end of the bolt 5 is subjected to force.

[0028] Two extrusion blocks 401 that can move up and down are connected to the bottom of the bolt 5, and two reinforcement blocks 402 that can move left and right are arranged at the bottom of the positioning pin 4. The reinforcement blocks 402 and the extrusion blocks 401 are pressed against each other by the bolt 5.

[0029] A chamfer 4022 is provided on the outer side of the bottom of the reinforcement block 402 to facilitate the connection between the positioning pin 4 and the pin hole 3.

[0030] A limiting block 4021 is disposed on the top of the reinforcing block 402 , a limiting groove 403 is provided inside the positioning pin 4 , and the limiting block 4021 is slidably connected in the limiting groove 403 .

[0031] In summary, the extrusion block 401 is used to press the reinforcement block 402 so that the reinforcement block 402 slides outward until the positioning pin 4 is fixed and pressed against the new product tooling 6. A coordinate system for installation is formed through multiple pin holes 3. Different tooling products use different coordinates, which is easy to operate, improves work efficiency, and improves the stability of processing dimensions.
