Detailed ways

Embodiment: As shown in Figure 1 and Figure 2, a flatness testing machine of the present invention includes a machine platform 1, a lifting mechanism 2, a detection device 3 and a jig 4, and the lifting mechanism 2 is fixed on the machine platform 1, the detection device 3 is fixed on the liftable part of the lifting mechanism 2, the jig 4 is fixed on the top of the machine 1 corresponding to the detection device 3, and the detection device 3 includes sequentially from top to bottom Set upper plate 31, equal height block 32, lower plate 33 and pressing plate 34, this upper plate 31, lower plate 33 and pressing plate 34 are parallel, on this lower plate 33, be provided with some detection needles, described detection needle is located at The lower plate 33 protrudes from the pressing plate 34 .

The lifting mechanism 2 includes a bracket 21 fixed on the top of the machine table 1, the liftable part is a cylinder 22, the cylinder shaft of the cylinder 22 is arranged on the bracket 21 downward, and the detection device 3 is fixed on the cylinder on axis.

The jig 4 includes a bottom plate 41 on which a bottom mold 42 is fixed, and the bottom mold 42 is provided with the same number of detection contacts 43 corresponding to the detection pins.

An insulating part is provided on the bottom mold 42 along the periphery of the detection contact 43 . It is prevented that the leakage of one detection contact 43 makes the rest of the detection contacts 43 conduct, resulting in inaccurate detection.
