The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, a positioning fixture for irregularly shaped blocks is provided.

[0018] Please refer to the instruction manual appendix. Figure 1-5 According to an embodiment of the present invention, a positioning fixture for irregularly shaped blocks includes a support platform 1. Multiple support grooves 2 are evenly distributed on the upper surface of the support platform 1. Each support groove 2 is fitted with a clamping assembly 4 via positioning bolts 3. The clamping assembly 4 includes an OK clamp body 41, which is installed within the support groove 2 via positioning bolts 3. Connecting holes 42 are respectively provided at the left and right ends of the OK clamp body 41. Clamping blocks 44 are fitted at both ends of the OK clamp body 41 via fixing bolts 43 and connecting holes 42. The clamping block 44 is provided with a second clearance groove 45, which cooperates with the first clearance groove 7. The bottom wall of the bearing groove 2 is provided with a positioning hole 10, and the bottom end of the positioning bolt 3 on the OK fixture body 41 is connected to the positioning hole 10. Product grooves 5 are provided on both the left and right sides of the bearing groove 2. The bottom wall of the product groove 5 is provided with a bottom groove 6. The bearing platform 1 on one side of the product groove 5 is also provided with a first clearance groove 7. Chip removal grooves 8 are provided on both the front and rear sides of the upper end of the bearing platform 1. The bottom end of the bearing platform 1 is provided with a magnetic base 9.

[0019] In the above technical solution, by setting multiple bearing grooves 2 and corresponding clamping components 4, multiple irregularly shaped workpieces can be clamped at the same time, which significantly improves the number of single processing and production efficiency; the cooperative design of product groove 5, bottom groove 6 and clearance groove adapts to the irregularly shaped block structure, ensures accurate positioning and provides sufficient processing space; chip removal groove 8 and inclined bottom wall structure facilitate chip removal, keep the working area clean and reduce downtime for cleaning; at the same time, magnetic base 9 allows tooling fixtures to be quickly installed on the machine tool worktable, which is conducive to improving changeover efficiency and positioning stability.

[0020] Among them, the bottom of the chip removal groove 8 located at the rear is inclined, which makes it easy for the chips to be discharged backward under the force of gravity or the flushing of cutting fluid.

[0021] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 2 , Figure 4 and Figure 5 The product groove 5 is used to accommodate the product body 11.
