[0007] Furthermore, the bottom of the product tooling protrudes downward, and the first mounting portion is formed by the protrusion.

[0008] Furthermore, the top of the tooling chassis body has a downward depression, and the second mounting portion is formed by the depression.

[0009] Furthermore, the protrusion and the depression are both circular, the first mounting portion is located at a middle position of the bottom of the product tooling, and the second mounting portion is located at a middle position of the top of the tooling chassis body.

[0010] Furthermore, a workbench is provided, and the tooling chassis body is fixedly connected to the workbench through a plurality of countersunk bolts, and the workbench drives the product tooling and the tooling chassis body to rotate.

[0011] Furthermore, the product tooling is fixedly connected to the product tooling by a plurality of countersunk bolts.

[0012] Furthermore, a positioning expansion sleeve is provided in the first positioning hole, and the positioning expansion sleeve is adaptively arranged on the positioning pin.

[0013] Furthermore, the positioning expansion sleeve has a plurality of notches arranged along the circumferential direction.

[0014] Furthermore, the gap includes a first section and a second section, the first section is located on the upper side of the second section and is connected to the second section, the first section is rectangular, and the second section is circular.

[0015] Furthermore, the inner wall of the positioning expansion sleeve gradually narrows from top to bottom.

[0022] The utility model discloses a tool chassis capable of rapid positioning and production change. An implementation manner of the utility model is described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a tooling chassis that can be quickly positioned and changed, includes a tooling chassis body 2, a workbench 3, and several product tools 1 that can achieve specific functions. The bottom middle position of the product tooling 1 protrudes downward, the protrusion is circular, and the protrusion forms a first mounting portion 7. Figure 2 As shown, the center of the top of the tooling chassis body 2 is recessed downward in a circular shape, forming a second mounting portion 8. The product tooling 1 is located on the top of the tooling chassis body 2 and is inserted into the second mounting portion 8 through the first mounting portion 7 to achieve a quick connection with the tooling chassis body 2.

[0024] like Figure 3 As shown, one side of the product tooling 1 has a first positioning hole 4 that runs through in the up-down direction, and the tooling chassis body 2 has a second positioning hole 6 that matches the first positioning hole 4. The first positioning hole 4 and the second positioning hole 6 are along the same axis, and a positioning tension pin is provided inside. The positioning tension pin includes a positioning sleeve 5 and a positioning pin. The positioning sleeve 5 is arranged on the lower side of the first positioning hole, and the top opening of the positioning sleeve 5 is circumferentially arranged with a number of notches that run through inside and outside. Combined Figure 4 and Figure 5 As shown, the gap is divided into a first section and a second section, the first section is rectangular, and the second section is circular. The first section is located on the upper side of the second section and adjacent to the opening of the positioning sleeve 5. The product tooling 1 is inserted into the first positioning hole 4 and the second positioning hole 6 through the positioning tension pin. The staff assists the product tooling 1 to quickly position through the first positioning hole 4 and the second positioning hole 6. The positioning sleeve 5 is mounted on the corresponding positioning pin to prevent the positioning pin from moving. In this embodiment, the positioning tension pin is an inner expansion positioning pin, and the inner wall of the positioning sleeve 5 gradually narrows from top to bottom to achieve a tightening effect on the positioning pin. The product tooling 1 is fixedly connected to the tooling chassis body 2 by a number of countersunk bolts.

[0025] The tooling chassis body 2 is mounted on top of a workbench 3. The top of the tooling chassis body 2 has several countersunk holes along its circumference. Each countersunk hole is adapted to accommodate a countersunk bolt. The tooling chassis body 2 is fixedly connected to the workbench 3 via these countersunk bolts. In this embodiment, the workbench 3 serves as the equipment's four-axis system, driving the tooling chassis body 2 and the product tooling 1 to rotate simultaneously.

[0026] The tool chassis body 2 can be connected to a variety of product fixtures 1 that perform specific functions. The operator fits the first mounting portion 7 of the product fixture 1 into the second mounting portion 8 of the tool chassis body 2. The operator then adjusts the position of the first locating hole 4 relative to the second locating hole 6 so that the first and second locating holes 4 and 6 lie along the same axis. The operator then inserts the positioning tension pin into both the first and second locating holes 4 and 6. The positioning sleeve 5 secures the positioning pin, preventing it from moving within the first and second locating holes 4 and 6, thereby preventing relative rotation between the product fixture 1 and the tool chassis body 2. The first and second locating holes 4 and 6 coordinate with each other on the work chassis body to assist in zero-point positioning of each product fixture 1, ensuring precise positioning relative to the angular coordinate system of the workbench 3 after each replacement of the product fixture 1. The first and second locating holes 4 and 6, along with the positioning tension pin, ensure that the fit between the product fixture 1 and the tool chassis body 2 can reach an accuracy of 0.005mm, meeting the requirements of high-precision production.

[0027] Each product fixture 1 utilizes a modular design, with each module dedicated to a specific processing or assembly function. Workers can select the appropriate product fixture 1 based on the specific processing task. Each fixture 1 can be quickly and accurately installed on the fixture chassis 2, achieving precise positioning, facilitating subsequent processing operations.

[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
