Detailed Description
The invention is further illustrated below with reference to the figures and examples.
As shown in fig. 1, the workpiece structure of the present invention is an L-shaped structure, which includes a bottom side and a side, where a plurality of punching holes are disposed, and the punching hole detection mechanism of the present invention is used to detect through holes of all punching holes on a workpiece, and determine whether there is a blind punching hole.
The detection mechanism of the present invention will now be further described with reference to fig. 1 to 6. The device mainly comprises a fixed support 1, a workpiece fixing seat 2 arranged on the fixed support 1, an upper detection assembly 3 arranged above the workpiece fixing seat 2, a side detection assembly 4 arranged on the upper detection assembly 3 and a PLC (programmable logic controller); wherein, be equipped with a plurality of spacing posts 21 around work piece fixing base 2, this spacing post is used for fixing L type structure work piece base up on work piece fixing base 2 to with carry out the through-hole and detect. The upper surface of the fixed support 1 is provided with a first slide rail 11, the lower surface of the workpiece fixed seat 2 is provided with a first slide block, the first slide block is arranged on the first slide rail 11 and can move back and forth along the first slide rail to drive the workpiece to enter a detection area, and the driving action can be realized by a motor or an air cylinder.
As shown in fig. 5 and 6, the upper detection assembly 3 includes an upper fixing bracket 31, an upper fixing plate 32, and a first sensor assembly 33 provided at the upper fixing plate 32; the upper fixing plate 32 is fixed on the workpiece fixing seat 2 through the upper fixing bracket 31 and is located above the workpiece fixing seat, specifically: the upper surface of the upper fixing bracket 31 is provided with a second slide rail 34, the lower surface of the upper fixing plate 32 is provided with a second slide block 35, and the second slide block 35 is arranged on the second slide rail 34 and can move back and forth along the second slide rail to drive the upper detection assembly 3 and the side detection assembly 4 to detect a workpiece.
