A support mechanism and a detection position mechanism are also installed on the top of the mounting plate. The support mechanism is used to support the workpiece, on which several inspection areas are formed. Several through holes are opened in a single inspection area. The detection position mechanism includes several detection positions, which are set one-to-one with the inspection areas. A detection hole is set in a single detection position, and the detection hole is set one-to-one with the through hole.

[0006] The workpiece is positioned directly above the detection station mechanism under the support of the support mechanism. At the same time, each individual area to be inspected is evenly spaced from the flatness detection end face of the corresponding detection station, thereby forming a detection gap.

[0007] The flatness of the workpiece is detected by inserting a scribing rod into each detection gap one by one.

[0008] The hole tolerance of the workpiece is detected by inserting the detection pin assembly one by one into each through hole and the corresponding detection hole position.

[0016] The top end face of the single-angle base is formed with a slope.

[0017] The detection pin assembly includes a first detection pin for detecting the hole position tolerance of a first through hole and a second detection pin for detecting the hole position tolerance of a second through hole.

[0018] The structure of the support mechanism is as follows: it includes several support columns of equal length, each support column is mounted on the top of the mounting plate via a support base, and a positioning block for positioning the workpiece is provided on the top end face of each support column.

[0019] Several positioning grooves are provided on the end face of the workpiece. Each positioning groove corresponds to a positioning block. The workpiece is positioned by inserting the positioning block into the corresponding positioning groove.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] The structure and function of this utility model are as follows:

[0037] like Figures 1-7As shown, a detection device specifically designed for lidar brackets includes a mounting plate 1. A detection pin assembly and a scribing rod 8 are placed on the top of the mounting plate 1. A support mechanism 2 and a detection position mechanism 3 are also mounted on the top of the mounting plate 1. The support mechanism 2 supports a workpiece 10, on which several inspection areas are formed. Several through holes are formed within each inspection area. The detection position mechanism 3 includes several detection positions, each corresponding to one of the inspection areas. Each detection position contains a detection hole, which corresponds to one of the through holes. The workpiece 10 is positioned directly above the detection position mechanism 3 under the support of the support mechanism 2. Simultaneously, each inspection area is evenly spaced from the flatness detection end face of its corresponding detection position, forming a detection gap. The flatness of the workpiece 10 is detected by inserting the scribing rod 8 into each detection gap. The hole position tolerance of the workpiece 10 is detected by simultaneously inserting the detection pin assembly into each through hole and its corresponding detection hole. By setting up the support mechanism 2, the detection position mechanism 3, the detection pin assembly and the scribing bar 8, the hole position tolerance and flatness of the workpiece 10 can be quickly, accurately and non-destructively inspected, thereby achieving full inspection and ensuring product quality.

[0038] In this utility model, the workpiece 10 is a laser radar bracket. The inspection area on the workpiece 10 includes a first inspection area, a second inspection area, and a third inspection area. At least one first through hole 11 is formed in each of the first, second, and third inspection areas. At least one second through hole 12 is formed in each of the second and third inspection areas. The diameter of the second through hole 12 is larger than the diameter of the first through hole 11. Specifically, as shown... Figure 4 As shown, the first inspection area includes two first through holes 11, the second inspection area includes one first through hole 11 and one second through hole 12, and the third inspection area includes one first through hole 11 and two second through holes 12. Therefore, in this utility model, the hole position tolerance and the flatness of the hole periphery plane need to be inspected for a total of seven through holes.

[0039] like Figure 6As shown, the structure of the detection position mechanism 3 is as follows: it includes a first detection position corresponding to the first inspection area, a second detection position corresponding to the second inspection area, and a third detection position corresponding to the third inspection area; the first, second, and third detection positions all include an angle base 301, and at least one first guide sleeve 303 is installed on the top of each angle base 301; at least one second guide sleeve 304 is installed on the top of each angle base 301 in the second and third detection positions; the top end face of the first guide sleeve 303 and the top end face of the second guide sleeve 304 correspond to the flatness detection end face; the first guide sleeve 303 is corresponding to the first through hole 11, and a first slot is opened on each first guide sleeve 303, the diameter of which is smaller than the diameter of which is ...

[0040] The top end face of the single angle base 301 is formed with an inclined surface 302. By setting the inclined surface 302, the top end face of the guide sleeve can be parallel to the circumferential plane of the corresponding through hole, thereby facilitating flatness inspection.

[0041] The inspection pin assembly includes a first inspection pin 5 for inspecting the hole position tolerance of the first through hole 11, and a second inspection pin 6 for inspecting the hole position tolerance of the second through hole 12. Both the first inspection pin 5 and the second inspection pin 6 have cylindrical inspection heads at their ends. By inserting the inspection heads into the corresponding through holes and inspection positions, the hole position tolerance of the corresponding through holes can be quickly determined. The diameter of the inspection head of the first inspection pin 5 is smaller than the diameter of the inspection head of the second inspection pin 6.

[0042] In this invention, the end of the scribing rod 8 is provided with a cylindrical detection rod. By inserting the detection rod into the detection gap, the flatness of the corresponding through hole circumferential plane can be quickly determined.

[0043] like Figure 5 As shown, the structure of the support mechanism 2 includes several support columns 202 of equal length. Each support column 202 is mounted on the top of the mounting plate 1 via a support base 201. A positioning block 203 for positioning the workpiece 10 is provided on the top end face of each support column 202. By setting the support mechanism 2, the workpiece 10 can be stably supported.

[0044] Several positioning grooves 13 are formed on the end face of the workpiece 10. The positioning grooves 13 are set one-to-one with the positioning blocks 203. By inserting the positioning blocks 203 into the corresponding positioning grooves 13, the workpiece 10 is positioned. By setting the positioning blocks 203 to correspond with the positioning grooves 13, the workpiece 10 can be positioned quickly and accurately to ensure the continuity and consistency of the inspection.

[0045] The detection pin assembly is placed on top of the mounting plate 1 via the first mounting bracket 7; the scribing rod 8 is placed on top of the mounting plate 1 via the second mounting bracket 9. The first mounting bracket 7 and the second mounting bracket 9 are used to ensure that the work surface is neat and orderly.

[0046] Several feet 4 are fixed to the bottom of the mounting plate 1. The feet 4 are made of rubber and are used to support the entire testing device and ensure the overall balance of the testing device.

[0047] The working process of this utility model is as follows:

[0048] like Figures 2-3 As shown, the workpiece 10 is placed on the support mechanism 2 by first aligning the positioning groove 13 with the corresponding positioning block 203 and inserting each positioning block 203 into the corresponding positioning groove 13.

[0049] After the workpiece 10 is placed in place, a detection gap m is formed between the circumferential plane of its through hole (part of the bottom end face of the workpiece 10) and the corresponding flatness detection end face in the detection mechanism 3 (i.e. the top end face of the corresponding first guide sleeve 303 or second guide sleeve 304); and each through hole is aligned with the corresponding detection hole position.

[0050] like Figure 7 As shown, by using the first detection pin 5, it is inserted one by one into the first slot on the four first through holes 11 and the corresponding first guide sleeve 303, and by using the second detection pin 6, it is inserted one by one into the second slot on the three second through holes 12 and the corresponding second guide sleeve 304.

[0051] When the first detection pin 5 and the second detection pin 6 can be smoothly inserted and removed, it indicates that the hole position tolerance of the corresponding through hole meets the quality requirements; otherwise, the hole position tolerance of the corresponding through hole does not meet the quality requirements.

[0052] By using a scriber 8, inserting it into each of the seven test gaps m, if the scriber 8 can be smoothly inserted and removed, and if the outer contour of the scriber 8 can make contact with the corresponding hole periphery plane and the top end face of the guide sleeve respectively, it indicates that the flatness of the corresponding through hole periphery plane meets the quality requirements; otherwise, the flatness of the corresponding through hole periphery plane does not meet the quality requirements.

[0053] When the hole position tolerances of the seven through holes and the flatness of the corresponding hole circumference planes meet the quality requirements, the workpiece 10 meets the acceptance criteria and is judged as a qualified product; otherwise, the workpiece 10 is judged as a defective product.

[0054] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
