Description

Technical Field

[0001] This utility model relates to the field of remote sensing cover plate detection tooling technology, specifically a remote sensing cover plate inclined side angle detection device. Background Technology

[0002] The telemetry cover plate is an arc-shaped part. It is arc-shaped at the top and bottom, and the left and right sides are inclined planes passing through the center of the arc. Only the front and back sides are straight. The central axes of the four holes on the arc surface all pass through the center of the arc.

[0003] It is difficult to inspect the form and position accuracy and dimensional accuracy of parts using traditional methods, especially the two beveled edges on the left and right sides and the four beveled holes on the arc surface. If their positional accuracy is out of tolerance, it will affect subsequent assembly. In addition, since these are batch parts, this brings great difficulties to the inspectors. Designing a set of inspection fixtures to quickly inspect parts is an urgent task. Utility Model Content

[0004] The purpose of this invention is to provide a remote sensing cover plate inclined angle detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A telemetry cover plate hypotenuse angle detection device includes:

[0007] The base has a supporting curved surface at its upper end that matches the arc-shaped bottom surface of the telemetry cover plate;

[0008] The inclined angle detection component includes a go gauge and a no-go gauge, wherein the angle of the detection inclined surface of the go gauge is smaller than the angle of the detection inclined surface of the no-go gauge, and the angle value of the two covers the design tolerance range of the inclined angle of the telemetry cover plate.

[0009] The screw hole detection assembly includes four symmetrically opened detection holes on the base. The diameter of the detection holes is larger than the design diameter of the countersunk screw holes of the telemetry cover plate, and their distribution positions correspond to the design positions of the countersunk holes of the cover plate.

[0010] As a further improvement of this utility model: the included angle of the detection inclined surface of the go gauge is 43°54′, and the included angle of the detection inclined surface of the no-go gauge is 43°57′.

[0011] As a further improvement of this utility model, the diameter of the detection hole is 4.2 mm.

[0012] As a further improvement of this utility model, the radius of curvature of the supporting surface of the base is consistent with the designed radius of curvature of the arc-shaped bottom surface of the telemetry cover.

[0013] As a further improvement of this utility model, the detection surfaces of the go gauge and no-go gauge are provided with grooves that match the arc-shaped contour of the telemetry cover plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves efficient and accurate detection of the angle of the oblique side of a telemetry cover plate through the coordinated design of the oblique side angle detection component and the supporting curved surface; the angle range of the go gauge and the no-go gauge strictly covers the design tolerance, and with the groove structure matching the arc contour of the cover plate, it can quickly determine whether the angle of the oblique side is qualified, avoiding the assembly problems caused by angle deviation in traditional detection methods, significantly improving the detection accuracy and batch detection efficiency, while reducing the dependence on the skill level of the operator.

[0016] 2. The screw hole detection component of this utility model adopts a symmetrically distributed detection hole and round bar insertion method. Through the hole diameter difference design and the common center characteristic of the axis, it realizes the integrated detection of the positional accuracy of countersunk holes. This structure simplifies the verification process of multi-hole form and position tolerance on complex arc surfaces. It is easy to operate and the results are intuitive, which greatly shortens the detection time and reduces the labor intensity. At the same time, it effectively ensures the compatibility of product assembly, and has significant economic and practical advantages. Attached Figure Description

[0021] Please see Figures 1-3 In this embodiment of the utility model, a telemetry cover plate inclined side angle detection device includes:

[0022] The base 1 has a support surface at its upper end that matches the arc-shaped bottom surface of the telemetry cover plate. The radius of curvature of the support surface is consistent with the design radius of curvature of the arc-shaped bottom surface of the telemetry cover plate (tolerance ±0.005mm), which can ensure that the telemetry cover plate is stably and accurately attached when placed on the base, providing a reliable positioning basis for subsequent detection operations.

[0023] The inclined angle detection component 2 includes a go gauge and a no-go gauge. The inclined angle of the go gauge is smaller than that of the no-go gauge, and the angle between the two covers the design tolerance range of the inclined angle of the telemetry cover plate. The inclined angle of the go gauge is 43°.

[0024] 54′, the included angle of the bevel of the stop gauge is 43°57′, and the included angle between the two covers the included angle of the bevel of the telemetry cover plate of 44°.

[0025] The design tolerance range of (-5.8′, -3.2′) can be used in conjunction with the go gauge and no-go gauge to quickly and accurately determine whether the included angle of the left and right hypotenuses of the telemetry cover plate is within the acceptable range.

[0026] The inspection surfaces of the go gauge and no-go gauge are provided with grooves that match the arc-shaped contour of the telemetry cover plate;

[0027] The screw hole inspection component 3 includes four symmetrically arranged inspection holes on the base 1. The diameter of the inspection holes is 4.2 mm, which is larger than the design diameter of the countersunk screw holes of the telemetry cover plate. The distribution of the inspection holes corresponds to the design position of the countersunk screw holes of the cover plate. The purpose of this design is to facilitate the insertion of a round bar for inspection. If the round bar can be smoothly inserted into the holes of the telemetry cover plate and the tooling, it indicates that the positions of the four holes on the telemetry cover plate are qualified.

[0028] The four countersunk screw holes on the arc surface of the telemetry cover are M4 holes.

[0029] The working principle of this utility model is as follows:

[0030] Place the cover plate to be tested: Place the telemetry cover plate to be tested on the support curved surface of base 1, ensuring that the arc-shaped bottom surface of the cover plate fits against the support curved surface of the base; if the left and right inclined surfaces of the cover plate can smoothly fit against the detection inclined surface of the go gauge (without gap or jamming), it means that the angle of the inclined side is ≥43°54′, which meets the minimum limit requirement; if the inclined surface of the cover plate cannot fit against the detection inclined surface of the no-go gauge (i.e., the no-go gauge cannot be inserted or there is a significant gap), it means that the angle of the inclined side is ≤43°57′, which does not exceed the maximum limit; the angle of the inclined side is qualified only when the cover plate passes through the go gauge (≥43°54′) and is rejected by the no-go gauge (≤43°57′).

[0031] Screw hole inspection: Insert four round rods with a diameter of 4.2mm into the four countersunk screw holes on the arc surface of the telemetry cover plate and the corresponding inspection holes on the base 1, respectively. If all four round rods can be inserted smoothly without obvious gaps or jamming, it can be determined that the position of the four countersunk screw holes on the telemetry cover plate is qualified, and the hole spacing in the y-axis direction and the included angle between the two hole axes in the x-axis direction meet the design requirements. Conversely, if any round rod cannot be inserted smoothly, it indicates that there is a deviation in the position of the screw hole, and the cover plate is unqualified.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
