Description

Technical Field

[0001] The utility model relates to the technical field of aircraft assembly and manufacturing, and more specifically, to a quick inspection card board for rivet heads. Background Art

[0002] Rivet riveting is a common connection technology used to fix two or more workpieces together. In rivet riveting, holes are drilled in the workpieces, and then the rivets are inserted into the holes. By applying pressure to the rivets with a rivet forming tool, a head is formed at the tail of the rivet rod. There are two elements in the inspection index for the formation of the head, one is the diameter of the head, and the other is the height of the head. Usually, a rivet head card board is used to check whether the formation of the rivet head is qualified.

[0003] Most of the existing rivet head inspection tools are ordinary square inspection card boards. There are three inspection ports on the inspection card board, namely the through-end port, the non-through-end port, and the height port. Through these three ports, it is checked whether the formation of the head is qualified. However, the existing inspection card board can only be used to check some places with a relatively spacious working area and a large rivet spacing; for areas with a relatively narrow space and a small rivet spacing, it is difficult to check with an ordinary rivet head card board after the rivet rod is formed.

[0004] The Chinese utility model patent with the patent name of "a rivet head inspection card board" and the publication number of CN220366816U that has been publicly disclosed includes at least two detachably connected plate bodies. Through-end bays and non-through-end bays are provided at both ends of the plate bodies, and the calibers of the through-end bays and non-through-end bays on different plate bodies are different; the calibers of the through-end bays and non-through-end bays at both ends of the same plate body are respectively equal to the maximum and minimum values of the designed diameter of the rivet head to be inspected, and the thicknesses at both ends of the same plate body are respectively equal to the maximum and minimum values of the designed height of the rivet head to be inspected. This device can meet the inspection requirements for rivet heads of different specifications, and both ends of the plate body can extend into a specific position space for inspection.

[0005] Although this device can be used for the inspection of heads in narrow spaces and the inspection of heads of different specifications, when inspecting various indexes of the rivet heads, it still needs to check the same head multiple times to determine whether it is qualified, and the inspection efficiency is not high. Summary of the Utility Model

[0006] The purpose of this application is to provide a quick inspection card board for rivet heads, which solves the technical problems of inspecting the formation of rivet heads in narrow areas and completing the inspection of rivet heads of different specifications in a single time.

[0007] To solve the above technical problems, the following solution is adopted in this application:

[0008] A quick detection card board for rivet upset heads, including a card board handle, which is a rectangular plate. At both ends of the card board handle, a first detection card board and a second detection card board are respectively arranged. The first detection card board and the second detection card board are respectively rotatably connected to the corresponding ends of the card board handle through hinges.

[0009] Preferably, at the ends of the first detection card board and the second detection card board far from the card board handle, a through-end slot and a stop-end slot are both arranged.

[0010] Preferably, the through-end slot is a waist-shaped slot, the stop-end slot is a rectangular slot, and the through-end slot and the stop-end slot are connected.

[0011] Preferably, the caliber of the through-end slot at one end of the same detection card board is equal to the minimum value of the allowable diameter of the rivet upset head of the standard model for which it is used for detection, the caliber of the stop-end slot is equal to the maximum value of the allowable diameter of the rivet upset head of the standard model for which it is used for detection, and the thickness of the same detection card board is equal to the lowest height after the formation of the rivet upset head of the standard model for which it is used for detection.

[0012] Preferably, the caliber of the through-end slot on the first detection card board is inconsistent with the caliber of the through-end slot on the second detection card board.

[0013] Preferably, the caliber of the stop-end slot on the first detection card board is inconsistent with the caliber of the stop-end slot on the second detection card board.

[0014] Preferably, the thickness of the first detection card board is inconsistent with the thickness of the second detection card board.

[0015] Preferably, the first detection card board and the second detection card board rotate through the hinges corresponding to them, and the angle that can be rotated relative to the card board handle is 0 degree - 90 degrees.

[0016] The technical solution of this application has at least the following advantages and beneficial effects:

[0017] In this utility model, through the connection of the through-end slot and the stop-end slot, it can be determined whether the rivet upset head to be detected is qualified only through one detection, improving the work efficiency;

[0018] In this utility model, by setting two detection card boards, it can detect the rivet upset heads of two specifications simultaneously, reducing the number of times of switching different detection card boards back and forth, and reducing the risk brought by multiple switching detection errors;

[0019] In this utility model, through the setting of the hinge, multi-angle detection of the detection card board is realized, which is convenient for the detection card board to extend into some special areas for detection, improving the applicability. Description of the Drawings

[0026] Embodiment

[0027] Please refer to Figures 1 - 3 , the present utility model provides a quick detection clamping plate for rivet heads, including a clamping plate handle 1, a first detection clamping plate 2, a second detection clamping plate 3, a through end slot 4, a non-through end slot 5, and a hinge 6.

[0028] Further, the clamping plate handle 1 is a rectangular plate member, and a first detection clamping plate 2 and a second detection clamping plate 3 are respectively arranged at both ends of the clamping plate handle 1, serving as carriers for two different specifications of rivet head rapid detection clamping plates.

[0029] The long strip-shaped clamping plate handle 1 is convenient to pick up during use and is suitable for some narrow areas.

[0030] Further, through slots 4 and non-through slots 5 are arranged at the ends of the first detection clamping plate 2 and the second detection clamping plate 3 away from the clamping plate handle 1.

[0031] Among them, the first detection clamping plate 2 is responsible for detecting the rivet heads of specification one, and the second detection clamping plate 3 is responsible for detecting the rivet heads of specification two. The rivet heads of the two specifications are inconsistent.

[0032] Preferably, the device can detect rivet heads of two different specifications at the same time, so that the staff does not need to frequently replace different clamping plates to detect different rivet heads, reducing the replacement times of the detection clamping plates and improving the detection efficiency.

[0033] Further, the through slot 4 is a waist-shaped slot, and the diameter of the waist-shaped slot is equal to the minimum value of the allowable diameter of the rivet head to be detected.

[0034] The non-through slot 5 is a rectangular slot, and the diameter of the rectangular slot is equal to the maximum value of the allowable diameter of the rivet head to be detected.

[0035] The thickness of the detection clamping plate is equal to the lowest height after the rivet head to be detected is formed.

[0036] Preferably, the through slot 4 and the non-through slot 5 are connected, so that the rivet head to be detected can continuously pass through the slots of the through slot 4 and the non-through slot 5 for detection. Thus, it can be detected whether the diameter of the rivet head is within the required range and whether the height of the rivet head meets the requirements only through one measurement.

[0037] When detecting, the slot of the first detection clamping plate 2 (or the second detection clamping plate 3) is close to the rivet head and the surface of the workpiece. If the rivet head can pass through the non-through slot 5 (the maximum allowable diameter) and cannot pass through the through slot 4 (the minimum allowable diameter), and the height of the rivet head is flush with or higher than the surface of the first detection clamping plate 2 (or the second detection clamping plate 3), it means that the rivet head is qualified in detection.

[0038] Preferably, the connected through slot 4 and non-through slot 5 enable the rivet head to continuously detect whether each index of the rivet head is qualified only through one detection, without the need for multiple detections, reducing the workload of the staff and saving the detection time.

[0039] In addition, the diameters of the through slots 4 and the not-go slots 5 on the two inspection cards are inconsistent, and the plate thicknesses of the two inspection cards are also inconsistent, so as to use the two inspection cards to inspect the rivet heads of two different specifications.

[0040] Further, the first inspection card 2 and the second inspection card 3 are respectively rotatably connected to one end of the card handle 1 through hinges 6. The two inspection cards can rotate through the corresponding hinges 6, and the angle at which they can rotate relative to the card handle 1 is 0°-90°, so that the inspection cards are convenient to use for inspection at different angles and in relatively narrow areas, improving their applicability.

[0041] So far, the embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions of the present invention according to the above description, and the scope of the present invention is defined by the appended claims.
