The guide part 62 is an inclined surface, and the inclined direction of the inclined surface gradually tilts towards the outside of the limiting post 6 along the direction in which the protrusion 22 of the product 2 is inserted into the relief groove 31. The limiting part 61 contacts the end 21 of the product 2.

[0034] In practice, the limiting post is located inside the end, and the two limiting posts are arranged symmetrically to each other.

[0035] The Z-down pressing mechanism 5 includes a pressing block 51, a pressing plate 52, and a rotary pressing cylinder 53 that drives the pressing block 51 to press the product 2. The pressing block 51 is located above the product 2 and is mounted on the pressing plate 52.

[0045] The working principle of this utility model is as follows: The product to be processed is placed on the platform, and the protrusion of the product corresponds to the clearance groove of the limiting block. The product is brought close to the limiting block, and the two limiting columns guide and limit the two ends of the product. The side pressure cylinder drives the pressing column to press the product. The pressure plate rotates first under the drive of the rotary pressing cylinder, so that the pressing block rotates to the top of the product. Then the rotary pressing cylinder drives the pressure plate to press down, so that the pressing block presses the product, ensuring the stability of the product positioning. Then the punch of the drilling device passes through the through hole to drill a hole in the product.
