[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 and 2 As shown, the utility model provides an aluminum alloy strut size detection device for an open car, including a detection component 10, the detection component 10 has two detection surfaces 20 arranged opposite to each other, and a placement space for placing a rod to be detected is formed between the two detection surfaces 20 to detect the length size of the rod, and the detection component 10 is provided with through holes respectively penetrating the two detection surfaces 20, and a bolt 40 that can move along its axial direction is provided in the through hole, and the bolt 40 is used to cooperate with the pin hole of the rod to detect the pin hole.

[0026] Specifically, when in use, the rod to be tested is placed in the placement space. When the rod is in a horizontal state, if the two end faces of the rod are simultaneously in contact with the two detection surfaces 20, it indicates that the length dimension of the rod is qualified; if one end face of the rod is in contact with one of the detection surfaces 20, and there is a certain gap between the other end face of the rod and the other detection surface 20, it indicates that the length dimension of the rod is smaller than the qualified dimension; if the rod is always in an inclined state when placed in the placement space, or cannot be placed horizontally in the placement space, it indicates that the length dimension of the rod is larger than the qualified dimension, and it is only necessary to place the rod between the two detection surfaces 20 to quickly detect whether the length dimension of the rod is qualified. For the rod that has passed the length test, the pin holes at both ends of the rod are further tested by bolts 40. The bolts 40 used are standard bolts 40, which can just match the matching pin holes. If the bolt 40 can be screwed in to the preset length or completely enter the pin hole, it can be judged that the depth and diameter of the pin hole are qualified. If the bolts 40 on both sides have the preset length or can completely enter the pin hole, it means that the pin holes at both ends of the rod meet the requirements. Otherwise, it means that at least one pin hole has a defect.

[0027] In one embodiment, the detection assembly 10 includes a base 11 and two detection plates 12, the two detection plates 12 are arranged on the base 11, and the opposite side of the two detection plates 12 is a detection surface 20. Through this embodiment, the distance between the two detection surfaces 20 can be easily changed or customized by means of the two detection plates 12.

[0028] Specifically, the lower ends of the two detection plates 12 are connected to the base 11 by welding or bolts 40, and the planes where the two detection plates 12 are located are perpendicular to the plane where the base 11 is located. When the two detection plates 12 are arranged side by side, the inner side surfaces of the two detection plates 12 are detection surfaces 20. Although the number of the detection surface 20 in the figure indicates a line, it is not convenient to show it in a plane, but it actually represents a plane.

[0029] In one embodiment, the through hole passes through the detection plate 12 in a direction perpendicular to the detection surface 20. Through this embodiment, it is convenient to detect the matching degree of the pin hole on the rod through the bolt 40 in the through hole.

[0030] Specifically, the rod is usually cylindrical in shape. To ensure the stability of installation, the axes of the two pin holes are colinear with the axis of the rod. Horizontal through holes are provided to ensure that the bolt 40 can be smoothly screwed in or out when mating with the pin hole.

[0031] In one embodiment, a positioning plate 30 is provided below the through hole on the detection surface 20 of the detection plate 12, and the positioning plate 30 is used to support the rod. In this embodiment, the positioning plate 30 can support the rod without manual support of the rod.

[0032] Specifically, when the positioning plate 30 supports the rod, the operator's hands are freed and no operator is required to stabilize the rod, which makes it easier to operate the bolt 40 to detect the pin hole.

[0033] In one embodiment, the positioning plate 30 is slidably connected to the detection plate 12 to adjust the distance between the positioning plate 30 and the through hole. Through this embodiment, when the rod is placed on the positioning plate 30, the pin hole of the rod can be aligned with the through hole on the detection plate 12.

[0034] Specifically, the positioning plate 30 is slidably connected to the detection plate 12, and a slide rail or a slider extending in a vertical direction is provided on the positioning plate 30 or the detection plate 12. The positioning plate 30 and the detection plate 12 are fixed by a bolt 40 assembly, or fixedly connected by clamping, to ensure that the positioning plate 30 is fixed on the detection plate 12 after the height adjustment is completed, and no random relative movement will occur after fixation.

[0035] In one embodiment, a positioning groove for limiting the rod is provided on the positioning plate 30. In this embodiment, the positioning groove can realize auxiliary positioning of the rod, so that the pin hole of the rod is quickly aligned with the through hole on the detection plate 12.

[0036] Specifically, the positioning groove is preferably an arc-shaped groove, which serves to limit the rod, that is, the two detection surfaces 20 limit the lateral ends of the rod, and the positioning groove limits the longitudinal sides of the rod, so that when the rod is placed on the positioning plate 30, its position can be automatically adjusted to ensure that the pin hole of the qualified rod can be aligned with the through hole, so that the operator can quickly operate the bolt 40.

[0037] In one embodiment, the two detection plates 12 are slidably connected to the base 11, so that the distance between the two detection plates 12 is adjustable. Through this embodiment, the distance between the two detection surfaces 20 can be adjusted to quickly detect rods of different lengths.

[0038] Specifically, the sliding connection between the detection plate 12 and the base 11 mainly serves to adjust the distance between the two detection surfaces 20. It may be a structural form in which a slide rail cooperates with a slide seat, or a slide block cooperates with a slide groove and then the distance is adjusted by a lead screw drive. Similarly, it may also be welded according to the actual standard length of the rod, etc. When the length needs to be adjusted, multiple groups of detection plates 12 with different spacings are welded on the base 11.

[0039] In one embodiment, the two detection surfaces 20 are parallel to each other.

[0040] Specifically, the two detection surfaces 20 are parallel to each other to adapt to the parallelism of the two end surfaces of the rod.

[0041] In one embodiment, the axes of the two through holes are collinear.

[0042] In one embodiment, the bolt 40 is threadedly engaged with the through hole. Through this embodiment, the detection plate 12 and the bolt 40 are kept relatively integral.

[0043] Specifically, when the length dimension of the rod is inspected, the bolt 40 is completely hidden in the through hole, that is, the bolt 40 will not protrude from the inspection surface 20; when the pin hole of the rod needs to be inspected, the bolt 40 is screwed in so that the protruding inspection surface 20 cooperates with the pin hole to inspect the pin hole.

[0044] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0045] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
