[0028] The positioning module is composed of a plurality of large reference blocks 8 and a plurality of small reference blocks 9 . The large reference blocks 8 are located on one side of the long side of the threshold beam 2 , and the small reference blocks 9 are located on one side of the short side of the threshold beam 2 .

[0029] A protrusion 80 is provided on the side of one end of the large reference block 8;

[0031] The protrusion 80 is connected to the threshold beam 2 by abutment, and the other end of the large reference block 8 is fixedly connected to one side of the workbench 1 by a bolt 1, so that the protrusion 80 fits tightly with the threshold beam 2, and forms a relative force with the reference block opposite to the threshold beam 2, which plays a role in positioning and clamping.

[0032] The second protrusion 90 is connected to the threshold beam 2 in abutment, and the other end of the small reference block 9 is fixedly connected to one side of the workbench 1 by bolt 2, so that the second protrusion 90 fits tightly with the threshold beam 2, forming a relative force with the clamping kit, and also plays a role of positioning and clamping.

[0033] A plurality of support blocks 5 are disposed at both ends of the other side of the tooling table 1 , and the support blocks 5 play a role in supporting the entire tooling table 1 .

[0034] The clamping module includes a plurality of dual-axis cylinders 6 and a plurality of clamping kits;

[0035] The fixed end of the double-axis cylinder 6 is fixedly connected to the workbench 1 by bolt three, and the free end of the double-axis cylinder 6 is in contact with the threshold beam 2. The double-axis cylinder 6 is mainly based on pneumatic drive, and the thrust is generated by the compressed air in the cylinder, so that the connecting block on the free end of the double-axis cylinder 6 fits tightly with the threshold beam 2, which plays a clamping role.

[0036] The clamping kit includes a support plate 3, one end of the support plate 3 is fixedly connected to the workbench 1 by bolt 4, the other end of the support plate 3 is fixedly connected to one end of the connecting plate 4 by bolt 5, the other end of the connecting plate 4 is in contact with the threshold beam 2, and a friction block is provided at the end of the connecting plate 4 in contact with the threshold beam 2 to prevent damage to the threshold beam during the tightening process.

[0037] One end of the support plate 3 is fixed to the outside of the large reference block 8 and the small reference block 9.

[0039] The specific working process of this utility model:

[0040] See also Figure 1-Figure 3 First, place threshold beams 2 of different sizes on the workbench 1, and fix the double-axis cylinder 6 on the workbench 1 with bolts around the threshold beam 2. When the double-axis cylinder 6 is working, the cylinder compressed air generates thrust, so that the connecting block on the double-axis cylinder 6 fits tightly with the threshold beam 2, forming a slight clamping effect. According to the shape of the threshold beam 2, a large reference block 8 is installed on the workbench 1 with bolts on the long side of the threshold beam 2, so that the protrusion 80 fits tightly with the threshold beam 2, and forms an interaction force with the relative reference block, which plays a role in positioning and clamping. Then, the small reference block 9 is fixed to the workbench 1 on the short side of the threshold beam 2 by bolts, so that the protrusion 90 is pressed against the threshold beam 2, and forms a relative force with the clamping kit, which also plays a role in positioning and clamping.

[0041] Secondly, one end of the support plate 3 is fixed to the workbench 1 by bolts on the outside of the large reference block 8 and the small reference block 9, and the other end is connected to the connecting plate 4. The other end of the connecting plate 4 is in contact with the threshold beam 2, forming an up and down force to press and fix the threshold beam 2.

[0042] Finally, one end of the probe 7 is detachably connected to the indentation of the sill beam 2, and the other end is connected to the machine. The probe head is moved to the indentation of the sill beam 2 to extract data. When the probe of the probe 7 contacts the indentation position of the sill beam 2, the probe will record the coordinate data of the touched point and transmit the extracted data to the machine. The machine calculates the contour parameters through the macro program. If the parameter value is within 0.8, the green light is on and the machine operates normally. If the parameter value is greater than 0.8, the red light is on and the equipment alarms, indicating that the sill beam 2 is placed upside down or the indentation is missing.
