Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-3, the cab skylight plane inspection device includes a supporting plate 1 on which a to-be-inspected piece 2 is mounted, and an inspection plate 3 located above the supporting plate 1, wherein a support 4 is disposed on the supporting plate 1, a hydraulic cylinder 5 is disposed at a lower end of the support 4, the hydraulic cylinder 5 drives the inspection plate 3 to make a linear reciprocating motion, a plurality of inspection units 6 are disposed at a top end of the inspection plate 3, each inspection unit 6 includes a receiving box 61 with an upper opening and a lower opening, a first rack 62 is fixedly disposed on one side wall of the receiving box 61, a second rack 63 is movably disposed on the other side wall of the receiving box 61, a gear 64 is adaptively disposed between the first rack 62 and the second rack 63, the gear 64 is connected with a support sleeve 66 through a rotating shaft 65, an inspection rod 7 is disposed at a bottom of the support sleeve 66, and the inspection rod 7. Under the condition that the planeness of the piece to be detected 2 reaches the standard, the lower surface of the detection plate 3 is attached to the upper surface of the piece to be detected 2; when the detection plate 3 is suspended, under the action of gravity, the gear 64 is positioned at the bottom end of the first rack 62, the detection rod 7 extends out of the bottom of the containing box 61, the hydraulic cylinder 5 acts to push the detection plate 3 to move downwards and attach to the piece to be detected 2, under the action of a jacking of the piece to be detected 2, the detection rod 7 moves upwards, the gear 64 rotates and drives the second rack 63 to move upwards and extend out of the top of the containing box 61, the planeness of the detection point reaches the standard, the upward bulge of the detection point and the downward depression of the detection point correspond to different extending lengths of the second rack 63, and therefore whether the piece to be detected 2 reaches the standard is directly and quickly judged, the structure is simple, and the detection result is; by using the matching of the gear 64 with the first rack 62 and the second rack 63, under the pushing of the detection rod 7, the gear 64 rotates and ascends, the linear displacement length of the gear 64 is smaller than that of the second rack 63, that is, the ascending distance of the detection rod 7 is smaller than that of the second rack 63, so that when the to-be-detected piece 2 has a trace amount of protrusion or depression, the detection unit 6 can also realize reliable detection.
The top end of the detection rod 7 is provided with scale marks, the top end of the containing box 61 is provided with a pointer 8, and the pointer 8 points to the scale marks. The scale mark, namely the arrival mark line, when the pointer 8 points to the arrival mark line, the to-be-detected part 2 is detected to be qualified, if the detection point of the to-be-detected part 2 corresponding to the detection unit 6 is convex, the scale mark is above the pointer 8, and if the detection point of the to-be-detected part 2 corresponding to the detection unit 6 is concave, the scale mark is below the pointer 8, so that the judgment is simple, convenient and quick; furthermore, according to the process parameters, the scale marks on the detecting units 6 at different positions are inconsistent, so that the corresponding detection results of the positions of the scale marks are accurate after the detecting plate 3 is attached to the piece to be detected 2.
The first rack 62 and the second rack 63 are oppositely arranged and are meshed with the gear 64. It is ensured that the gear 64 can move the second rack 63 in the same direction.
A sliding groove 9 is fixed on the other side wall of the accommodating box 61, a notch of the sliding groove 9 faces the gear 64, and the second rack 63 is movably arranged in the sliding groove 9. The sliding groove 9 is arranged, so that the second rack 63 can slide more smoothly, the second rack 63 can be limited, and the second rack 63 and the first rack 62 can be reliably meshed with the gear 64.
The bottom end of the first rack 62 is provided with a baffle 67. The stop plate 67 is a lower limit, and prevents the gear 64 from falling off when the detection plate 3 is suspended.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
