Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically a high-precision gap measuring instrument. Background Technology

[0002] In fields such as machinery manufacturing, equipment maintenance, and precision assembly, gap measurement is a key step in ensuring product quality and equipment operational stability.

[0003] Traditional gap measuring tools, such as ordinary calipers and feeler gauges, have many limitations: ordinary calipers lack precise quantitative reading devices and require indirect measurement with tools such as rulers, making it difficult to guarantee accuracy; while feeler gauges can be directly inserted into gaps, their rigid structure makes it difficult to conform to the measured surface for gaps in narrow, deep cavities or curved surfaces, easily leading to measurement deviations; some high-precision measuring instruments have complex structures, are cumbersome to operate, and require high skill levels from operators, making them unsuitable for the needs of rapid on-site measurement. Furthermore, the measuring heads of traditional measuring tools are mostly designed to be flat or of a single shape, unable to adapt to gaps of different shapes, thus limiting their applicability. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision gap measuring instrument to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision gap measuring instrument, comprising a first caliper, a second caliper, and a measuring head. The first caliper is provided with a second caliper in a symmetrical structure above it, and the right ends of the first caliper and the second caliper are rotatably connected by a connecting lug. The left ends of both the first caliper and the second caliper are provided with an integral measuring head, and the left ends of the two measuring heads are in contact.

[0006] The first caliper has an integrated handle A on its right end, and the second caliper has an integrated handle B on its right end.

[0030] Example

[0031] like Figure 1-8As shown, this utility model provides a technical solution: including a first caliper 1, a second caliper 2 and a measuring head 3. The first caliper 1 is provided with a second caliper 2 in a symmetrical structure above it, and the right ends of the first caliper 1 and the second caliper 2 are rotatably connected by a connecting ear 4. The left ends of the first caliper 1 and the second caliper 2 are both provided with a measuring head 3 in an integral structure, and the left ends of the two measuring heads 3 are in contact.

[0032] The first caliper 1 has an integrated handle A5 on its right end, and the second caliper 2 has an integrated handle B6 on its right end. The handles A5 and B6 are aligned vertically, and springs 8 are installed inside the left side of the handles A5 and B6 via connecting seats 7. The right end of the handle A5 is rotatably connected to the micrometer measuring device 11 via a connector 9, and the right end of the handle B6 is rotatably connected to the bearing 10. The upper end of the micrometer measuring device 11 passes through the interior of the bearing 10.

[0033] Both the first caliper 1 and the second caliper 2 have an arc-shaped structure, which allows the measuring head to open in the opposite direction when the two handles are opened.

[0034] The two measuring heads 3 are arranged in a staggered, tangential structure, which facilitates their staggered opening and allows for gap measurement.

[0035] The two measuring heads 3 have a conical structure, which facilitates the staggered opening of the measuring heads.

[0036] The first caliper 1, the second caliper 2, the handle A5, and the handle B6 form a rectangular strip structure, which facilitates the opening and adjustment of the handle.

[0037] The outer ends of handles A5 and B6 are arc-shaped, which facilitates the gripping of the handles.

[0038] The intersection point of the two measuring heads 3 and the center of the connecting ear are on the same horizontal straight line, which makes the measurement gap more accurate.

[0039] The center distance between the intersection of the two measuring heads 3 and the center of the connecting ear 4 is equal to 1 / 3 of the center distance between the connecting ear 4 and the micrometer measuring device 11.

[0040] Working principle:

[0041] Before use, ensure the device is in its initial state, with the measuring head 3 at the left end of the first caliper 1 and the second caliper 2 in contact, and the handles A5 and B6 kept aligned vertically by the spring force of the spring 8. The reading of the micrometer measuring device 11 is reset to zero or the initial reading is recorded.

[0042] The operator pinches handle A5 and handle B6 together to bring them closer together. At this time, the first caliper 1 and the second caliper 2 rotate around the connecting ear 4 as the fulcrum, and the two measuring heads 3 on the left end open accordingly. The spring 8 is compressed and stores elastic force.

[0043] Align the open measuring head 3 with the gap to be measured, ensuring that the arc-shaped left end of the measuring head 3 is aligned with the center of the gap, and that the staggered tangential structure of the two measuring heads 3 corresponds to the two sides of the gap.

[0044] Slowly release handles A5 and B6. Spring 8 releases its elastic force to push the handles back to their original position. First caliper 1 and second caliper 2 rotate in opposite directions. The two measuring heads 3 gradually approach each other under the action of the elastic force until they are in close contact with the two sides of the gap being measured. At this time, the intersection point of the measuring heads 3 corresponds to the gap width.

[0045] By rotating the adjustment knob of the micrometer measuring device 11, its upper end rotates within the bearing 10 until the micrometer measuring device 11 contacts and stabilizes with the handle B6. At this time, the value is read according to the scale of the micrometer measuring device 11, which is the precise width of the gap being measured.

[0046] After the measurement is completed, squeeze handle A5 and handle B6 together again to open the measuring head 3 and disengage it from the gap being measured. After releasing the handle, the device returns to its initial state under the action of spring 8. Clean the impurities on the surface of the measuring head 3 and then put it away.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
