To facilitate the installation and positioning of the alloy blades, as shown in the attached diagram... Figure 4As shown, a blade positioning groove 10 is provided on the upper part of the blade positioning seat 4. The blade positioning groove 10 is located on the upper part of the blade positioning seat 4. A groove-fitting support combined with an end-clamping clamping structure is adopted to accommodate the shape characteristics of the alloy blade. The blade positioning groove 10 on the upper part of the blade positioning seat 4 provides fitting, positioning, and support for the alloy blade. The clamping limit block 6, driven by the clamping cylinder 3, clamps and limits the installed alloy blade.

After installation, the positioning pin 8 at the lower part of the blade positioning seat 4 and the strong magnetic block in the positioning hole 9 are attracted and limited, completing the assembly of the fixture. During operation, the cutting edge of the alloy blade is fitted into the blade positioning groove 10 on the upper part of the blade positioning seat 4 with the cutting edge facing upward. Then, the clamping limiting block 6 is installed on the upper part of the clamping drive pin 5 by screwing. The positioning and installation of multiple alloy blades are completed in sequence. Then, the movable base 1 is driven to move down by the lifting and driving of the two sets of clamping cylinders 3. Under the drive of the clamping drive column 5, the clamping limit block 6 is pressed and limited with the middle of the alloy blade. With the fitting support of the blade positioning groove 10, the alloy blade can be stably installed. Then, the cutting edge of the alloy blade is modified by the grinding equipment. During the process, since the middle of the alloy blade is pressed and supported by the clamping limit block 6, it will not occupy the cutting edge space of the alloy blade. The modification of the alloy blade can be completed in a single clamping, without the need for multiple clamping, which can effectively improve the convenience of clamping and installing the alloy blade and the work efficiency of the modification operation.

[0025] In summary, this trimming fixture employs a slot-fitting support combined with an end-clamping clamping structure tailored to the shape characteristics of alloy inserts. The insert positioning slot 10 on the upper part of the insert positioning seat 4 provides fitting, positioning, and support for the alloy insert. The clamping limit block 6, driven by the clamping cylinder 3, clamps and limits the installed alloy insert. This ensures precise installation and stability of the alloy insert, improving trimming accuracy and fixture stability. Both the insert positioning seat 4 and the clamping limit block 6 are separate units, facilitating easy disassembly and replacement. They can be flexibly selected and replaced according to the insert type, meeting the clamping and installation needs of alloy inserts with different shapes and specifications. Compared to traditional clamping fixtures, this offers better adaptability. Furthermore, the installed alloy insert is clamped and limited in the middle of the tool body by the clamping limit block 6, without occupying the cutting edge space. A single clamping operation can complete the trimming of the alloy insert, eliminating the need for multiple clamping operations and improving trimming efficiency.
