[0028] Refer to the attached Figure 1 The present invention provides a measuring tool for testing automotive parts, including a delivery mechanism 1 and a measuring mechanism. The delivery mechanism 1 is used to convey automotive parts 2 to be tested, with adjacent automotive parts 2 spaced evenly apart. The delivery mechanism 1 can be a conveyor belt, and a plurality of locating pins 101 are evenly spaced along the axial centerline of the conveyor belt. The center holes of the automotive parts 2 to be tested are fitted onto the locating pins 101, centered on the parts 2 to be tested.

[0029] The measuring mechanism includes a first measuring assembly 3 and a rear-mounted second measuring assembly 4. The first measuring assembly 3 and the second measuring assembly 4 are arranged in front and behind each other along the conveying direction of the inspection mechanism 1, with the first measuring assembly 3 in front and the second measuring assembly 4 in the back. The spacing between the first measuring assembly 3 and the second measuring assembly 4 is smaller than the spacing between adjacent automotive parts 2 to be tested. The first measuring assembly 3 includes a first follower assembly and a first detection circuit. The first follower assembly includes a first base 301, a first sliding sleeve 303, a first spring 304, a first measuring rod 305, and a first conductive sheet 306. The first detection circuit includes a first circuit power supply 309, a first response electrical device, and a pair of first contacts 311. For details, see Figure 2As shown, a first base 301 is perpendicularly mounted on the side of the inspection mechanism 1. A slide 302 perpendicular to the feeding direction is provided on the surface of the first base 301. A first sleeve 303 has a central hole, and a slider is provided at the bottom to slidably engage with the slide 302. The first sleeve 303 slides perpendicular to the feeding direction. A first measuring rod 305 slides through the central hole. The distance between the inner measuring end of the first measuring rod 305 and the axis of the inspection mechanism 1 is the minimum theoretical radius of the automotive part 2 to be tested. A first spring 304 is sleeved on the outer end of the first measuring rod 305. One end of the first spring 304 is fixedly connected to the first sleeve 303, and the other end is fixedly connected to the inner end of the outer end of the first measuring rod 305. A first conductive sheet 306 is fixedly mounted on the outer end of the first measuring rod 305. The first measuring rod 305 is an insulating rod.

[0030] Of course, for automotive parts with different outer diameters, the measurement radius can be changed by moving the first sleeve 303 to adjust the distance between the inner measuring end of the first measuring rod 305 and the axis of the inspection mechanism 1. To clarify the current measurement radius, a scale mark 313 is provided on one side of the first base 301. This scale mark 313 indicates the distance between the first measuring rod 305 and the axis of the inspection mechanism 1. Furthermore, to secure the adjusted position of the first sleeve 303, a threaded adjustment rod 307 is provided on the other side of the first base 301. A stop plate 308 is provided at the end of the threaded adjustment rod 307. By turning the threaded adjustment rod 307, the stop plate 308 presses against the first sleeve 303, thereby securing the position of the first sleeve 303.

[0031] In the above, the first circuit power supply 309 is connected to the first response electrical device wire, and a pair of first contacts 311 are respectively provided at the positive and negative ends of the first detection circuit. In the natural state, the first conductive sheet 306 contacts the pair of first contacts 311, thereby conducting the first detection circuit. When the radius of the automotive part 2 to be tested passing through the first measuring rod 305 is greater than the theoretical minimum radius, the first measuring rod 305 is pushed outward by the automotive part 2 to be tested, the first conductive sheet 306 separates from the two first contacts 311, and the first detection circuit is disconnected.

[0032] In this embodiment, the first measuring assembly 3 and the second measuring assembly 4 are structurally identical, differing only in the distances between the first measuring rod 305 and the second measuring rod and the axis of the inspection mechanism 1. Specifically, the second detection circuit, the second measuring assembly 4, comprises a second follower assembly and a second detection circuit. The second follower assembly comprises a second base, a second sleeve, a second spring, a second measuring rod, and a second conductive sheet. The second detection circuit comprises a second circuit power supply, a second response electrical device, and a pair of second contacts. Specifically, the second base is perpendicularly disposed on the side of the inspection mechanism 1. A groove 302 perpendicular to the feed direction is provided on the surface of the second base. The second sleeve has a central sleeve hole, and a slider is provided at the bottom thereof for sliding engagement with the groove 302. The second sleeve slides perpendicularly to the feed direction. The second measuring rod slides through the central sleeve hole. The distance between the inner measuring end of the second measuring rod and the axis of the inspection mechanism 1 is equal to the maximum theoretical radius of the automotive part 2 to be tested. The outer end sleeve of the second measuring rod is provided with a second spring, one end of the second spring is fixedly connected to the second sliding sleeve, and the other end is fixedly connected to the inner end portion of the outer end of the second measuring rod. The second conductive sheet is fixedly arranged on the outer end portion of the outer end of the second measuring rod, and the second measuring rod is an insulating rod.

[0033] Of course, for automotive parts with different outer diameters, the measurement radius can be changed by moving the second sleeve to adjust the distance between the inner measuring end of the second measuring rod and the axis of the inspection mechanism 1. To clarify the current measurement radius, a scale mark 313 is provided on one side of the second base, which indicates the distance between the second measuring rod and the axis of the inspection mechanism 1. Furthermore, to secure the adjusted position of the second sleeve, a threaded adjustment rod 307 is provided on the other side of the second base. A stop plate 308 is attached to the end of the threaded adjustment rod 307. By tightening the threaded adjustment rod 307, the stop plate 308 presses against the second sleeve, thereby securing the position of the second sleeve.

[0034] In the above, the second circuit power supply is connected to the second response electrical device wire, and a pair of second contacts are respectively arranged at the positive terminal and negative terminal of the second detection circuit. In the natural state, the second conductive sheet contacts the pair of second contacts to conduct the second detection circuit. When the radius of the automotive part 2 to be tested passing through the second measuring rod is greater than the theoretical maximum radius, the second measuring rod is pushed outward by the automotive part 2 to be tested, the second conductive sheet separates from the two second contacts, and the second detection circuit is disconnected.

[0035] In addition, it should be noted that the minimum theoretical radius mentioned above is the standard radius of the automobile part - the lower tolerance, and the maximum theoretical radius is the standard radius of the automobile part + the upper tolerance. The first response device and the second response device are light-emitting diodes. Of course, a power switch 312 is provided on the first detection circuit and the second detection circuit. When not detecting, the first detection circuit and the second detection circuit are disconnected to avoid constant lighting.

[0036] In summary, the present application provides a measuring tool for automobile parts testing, the measuring principle of which is:

[0037] First, turn on the switches on the first and second detection circuits to check whether the circuits are energized normally. Then, place the automotive part 2 to be tested in the center of the inspection mechanism 1, and start the inspection mechanism 1 to send the automotive part 2 to be tested for inspection. When the automotive part 2 to be tested passes through the first measurement component 3 and the second measurement component 4 in sequence, the following three situations may occur:

[0038] First, if the radius of the automotive part 2 to be tested is smaller than the minimum theoretical radius, the automotive part 2 to be tested cannot contact the first measuring rod 305, let alone the second measuring rod. Therefore, the first conductive sheet 306 remains connected to the first detection circuit, the second conductive sheet remains connected to the second detection circuit, and the first response element 310 and the second response element remain illuminated.

[0039] Second: If the radius of the automotive part 2 under test is greater than the minimum theoretical radius and less than / equal to the maximum theoretical radius, the automotive part 2 under test passes through the first measuring rod 305 and is pushed to the sides, separating the first conductive sheet 306 from the first contact 311, disconnecting the first circuit, and turning off the first response element 310. However, when passing through the second measuring rod, the second measuring rod cannot be disconnected from the second contact, connecting the second circuit, and the second response element remains illuminated.

[0040] Third: If the radius of the automobile part 2 to be tested is greater than the maximum theoretical radius, then at this time, when the automobile part 2 to be tested passes through the first measuring rod 305 and the second measuring rod in sequence, both the first measuring rod 305 and the second measuring rod can be pushed outward, the first conductive sheet 306 is separated from the first contact 311, the first circuit is disconnected, the first response member 310 light is off, the second conductive sheet is separated from the second contact, the second circuit is disconnected, and the second response member light is off.

[0041] It can be seen that the present application provides a measuring tool for automobile part testing. During testing, the automobile part 2 to be tested passes through the first measuring component 3 and the second measuring component 4 in sequence:

[0042] If both the first response member 310 and the second response member remain in the on state, it means that the outer diameter of the tested automobile part is too small and does not meet the standard;

[0043] If the light of the first response member 310 is off and the light of the second response member remains on, it means that the outer diameter of the tested automobile part meets the standard;

[0044] If both the first response member 310 and the second response member are off, it means that the outer diameter of the tested automobile part is too large and does not meet the standard.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
