[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] The following describes the passage detection tooling of the embodiment of the utility model with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an embodiment of the utility model proposes a pass / stop detection tooling, comprising a plate body 1, a measuring groove 3 is provided on the plate body 1 along the length direction, the measuring groove 3 is suitable for placing the object to be measured, a tolerance groove 2 is provided at one end of the measuring groove 3, the length of the tolerance groove 2 is determined according to the tolerance range allowed by the object to be measured, the tolerance groove 2 is communicated with the measuring groove 3, the width of the tolerance groove 2 is greater than the width of the measuring groove 3, the depth of the tolerance groove 2 is greater than or equal to the depth of the measuring groove 3, and the measuring groove 3 is provided with a pick-up and placement groove 4 for taking and placing the object to be measured in the width direction.

[0025] The embodiment of the utility model can quickly detect whether the product size meets the tolerance range by providing the measuring slot 3 and the tolerance slot 2, converting the quantitative measurement method into the qualitative measurement method, which is easy to operate, improves work efficiency, and reduces labor costs. The pick-up and placement slot 4 is provided to facilitate quick product placement.

[0026] The width of the tolerance groove 2 is designed to be larger than the width of the measuring groove 3, making it easier to observe whether the end of the object under test is within the tolerance groove 2. The depth of the tolerance groove 2 is designed to be greater than or equal to the depth of the measuring groove 3 to ensure that the object under test is placed flat and the accuracy of the test is guaranteed.

[0027] When in use, place the detection tool flat on the workbench, place the object to be measured into the measuring slot 3 from top to bottom, adjust the position of the object to be measured so that one end of the object to be measured is against the end of the measuring slot 3 away from the tolerance slot 2, and observe whether the other end of the object to be measured is in the tolerance slot 2. If it is in the tolerance slot 2, it means that the length of the object to be measured is within the tolerance range; if not, it means that the length of the object to be measured is too small and does not meet the tolerance range; if the object to be measured cannot be placed in the measuring slot 3, it means that the length of the object to be measured is too large and does not meet the tolerance range.

[0028] It should be noted that the objects to be tested can be taken and placed manually or by mechanical equipment.

[0029] In some embodiments, both ends of the tolerance groove 2 extend toward both sides of the measuring groove 3 to form a T-shaped structure.

[0030] In some embodiments, the bottom surface of the tolerance groove 2 is flush with the bottom surface of the measuring groove 3. This ensures that the object to be tested is placed flat and the accuracy of the test is guaranteed.

[0031] In some embodiments, the pick-and-place slot 4 is located in the middle of the measuring slot 3 to facilitate the object to be measured to maintain balance during the pick-and-place process.

[0032] Furthermore, the pick-and-place slot 4 can be in various shapes, such as rectangular, semicircular, etc.

[0033] Furthermore, the pick-and-place slots 4 are respectively provided on both sides of the measuring slot 3 in the width direction.

[0034] In some embodiments, a plurality of measuring slots 3 are provided along the width direction of the plate 1 , and each measuring slot 3 is connected to a tolerance slot 2 , so as to measure objects to be measured of different specifications.

[0035] In some embodiments, the depth of the pick-and-place groove 4 is greater than or equal to the depth of the measuring groove 3, so as to facilitate the picking and placing of the object to be measured.

[0036] In some embodiments, all the measuring slots 3 and the placing and taking slots 4 are connected to each other.

[0037] In some embodiments, the pick-and-place slot 4 passes through both sides of the plate body 1 in the width direction.

[0038] In some embodiments, the upper edge of the measuring slot 3 is chamfered to facilitate alignment and placement of the object to be measured into the measuring slot 3 .

[0039] In some embodiments, the measuring slots 3 are rectangular structures, and the center lines of two adjacent measuring slots 3 along the length direction are parallel to each other.
