Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Examples

As shown in fig. 1, the tool fixture for drilling the cabinet frame is characterized in that the cabinet frame 1 is rectangular and is a nine-fold sectional cabinet formed by rolling by a rolling forming machine, the end of the upright of the cabinet frame 1 is provided with a plurality of U-shaped grooves 11 with openings facing the end, the outer side of the upright of the cabinet frame 1 is provided with a sectional plate, as shown in fig. 2, the U-shaped grooves 11 are formed in the sectional plate, and the sectional plate needs to be drilled with assembling holes 12 at two sides of the U-shaped grooves 11, as shown in fig. 3 (the assembling holes are drawn in the drawing).

As shown in fig. 4, the tooling fixture 2 includes a base 21, a positioning plate 22 disposed on the base 21, and a holding portion fixed at the bottom of the base 21, the holding portion of the embodiment is a columnar handle 27; a protruding positioning block 23 matched with the U-shaped groove 11 is arranged in the middle of the rear side of the positioning plate 22, positioning holes 25 are formed in the positioning plate 22 on two sides of the positioning block 23, and the positions of the two positioning holes 25 correspond to the positions of the assembling holes 12 to be drilled on two sides of the U-shaped groove 11 of the cabinet box frame 1; as shown in fig. 5 and 6, a base plate 24 parallel to the positioning plate 22 is further disposed on the base 21, a gap for inserting the profile plate at the end of the column is formed between the positioning plate 22 and the base plate 24, and the positioning block 23 is located in the gap; the substrate 24 is provided with a through hole 26 coaxially provided with the positioning hole at a position corresponding to the positioning hole 25.
