It is provided with a vertical mounting surface and a horizontal mounting surface respectively.

[0054] The top surface of the fixture mounting assembly 1 is the vertical mounting surface, used to support and mount the vertical machining fixture assembly 2. In this embodiment, according to actual production needs, the vertical machining fixture assembly 2 is provided with two sets of fixtures on the fixture mounting assembly 1. In other embodiments, several sets of fixtures can also be provided according to actual production needs. The vertical machining fixture assembly 2 is a vertical machining center fixture, located at the center of the top surface of the fixture mounting assembly 1.

[0055] The side of the fixture mounting assembly 1 is the horizontal mounting surface, used to support and mount the horizontal machining fixture assembly 3. In this embodiment, similarly, according to actual production needs, two sets of fixtures are correspondingly provided on the fixture mounting assembly 1 for the horizontal machining fixture assembly 3.

The horizontal machining fixture assembly 3 is a horizontal machining center fixture, located at the center of the side of the fixture mounting assembly 1, and as shown... Figure 1 and Figure 4 As shown, in this embodiment, since the center hole of the cleaver seat needs to be machined on a horizontal machining center, the cutting tool of the horizontal machining center needs to be inserted into it. Therefore, a through hole is also provided on the horizontal mounting surface to facilitate the passage of the cutting tool of the horizontal machining center to machine the center hole.

[0056] The hydraulic unit 4 is connected to the vertical machining fixture assembly 2 and the horizontal machining fixture assembly 3 through hydraulic pipes, and the clamping and fixing of the cleaver seat is controlled by hydraulic pressure.

The horizontal mounting surface is the surface of the horizontal fixture mounting plate 13, and the horizontal machining fixture assembly 3 is detachably connected and mounted on the horizontal mounting surface on one side of the horizontal fixture mounting plate 13.

[0061] Meanwhile, in order to maintain the stability of the I-beam structure of the fixture mounting assembly 1, in this embodiment, the fixture reinforcing rib plate 14 is also perpendicular to the fixture base plate 11 and the vertical fixture mounting plate 12, and is disposed on both sides of the horizontal fixture mounting plate 13. By providing the fixture reinforcing rib plate 14 between the fixture base plate 11 and the vertical fixture mounting plate 12, the I-beam structure of the fixture mounting assembly 1 is stabilized, and other functional equipment can be installed on the vertical mounting surface on the vertical fixture mounting plate 12 and the horizontal mounting surface on the horizontal fixture mounting plate 13.

The workpiece support 23 is connected to and controlled by the hydraulic unit 4 to support the inverted chopping block seat at the bottom.

[0065] Furthermore, since the vertical machining fixture assembly 2 is the first machining step of the splitter seat, and the machining cutting amount is large, in order to ensure that the splitter seat will not move during the machining process, the external positioning component 24 is also provided around the vertical clamping base 21 to clamp and position the side of the splitter seat base.

[0066] Furthermore, such as Figure 1 and Figure 4 As shown, in this embodiment, the external positioning component 24 specifically includes: external positioning seat 241, external positioning head 242, and part limiting rod 243;

[0077] As a component that directly abuts against and supports the anti-fall bar 331, one end of the anti-fall bar 331 is provided with the anti-fall hinge pin 333. The anti-fall hinge pin 333 is hinged to the anti-fall seat 332, so that the anti-fall bar 331 can rotate around the anti-fall hinge pin 333 relative to the anti-fall seat 332.

[0078] The elastic element 334 is disposed on the anti-fall seat 332. In this embodiment, the anti-fall seat 332 has a T-shaped structure.

[0084] Meanwhile, in this embodiment, the accumulator 41 and the pressure gauge 46 are also provided with protective covers. Since they are located between the fixture base plate 11 and the vertical fixture mounting plate 12, the protective covers are provided to prevent the processing debris from splashing and causing damage, thereby improving the stability of the fixture.

[0085] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the fixture base plate 11 is also provided with an air detection port 51 of the air source system 5, which is used by the air source system 5 to confirm the clamping status of the vertical machining fixture assembly 1 and the horizontal machining fixture assembly 2. Specifically, both the vertical machining fixture assembly 1 and the horizontal machining fixture assembly 2 are provided with air detection holes. When the splitting tool holder is clamped, the air detection hole is closed by the splitting tool holder, which indicates that the clamping is complete.
