[0029] Please see Figure 1 and Figure 2 As shown, this utility model is a blade battery housing length and width inspection tool, including an inspection plate 10, a clamp 30, and a go / no-go gauge 40. The surface of the inspection plate 10 is provided with a rectangular inspection groove 20, and the inner cavity size of the rectangular inspection groove 20 is determined according to the upper limit of the length and width of the blade battery housing 50. The clamp 30 is detachably connected to the middle position of the length side of the inspection plate 10, and the clamp 30 is used to fix the blade battery housing 50. The go / no-go gauge 40 is set on one side of the inspection plate 10 and is used to detect whether the length of the blade battery housing 50 is within the allowable tolerance range.

[0030] During the use of the inspection fixture in this application, the blade battery housing 50 to be inspected is placed in the rectangular inspection fixture slot 20. Since the inner cavity size of the rectangular inspection fixture slot 20 is determined according to the upper limit of the length and width of the blade battery housing 50, the following results can be obtained intuitively: when the blade battery housing 50 cannot be completely placed in the rectangular inspection fixture slot 20, it is determined that the width of the blade battery housing 50 exceeds the upper limit and is a non-conforming product; conversely, when the blade battery housing 50 is completely placed in the rectangular inspection fixture slot 20, it is determined that the width of the blade battery housing 50 is within the required upper limit, and then the length of the blade battery housing 50 is inspected.

[0031] When the blade battery housing 50 is being tested for length, the blade battery housing 50 is pushed to one end of the rectangular gauge groove 20, and a testing gap is formed between the other end of the length and the blade battery housing 50. At this time, the blade battery housing 50 is locked in the rectangular gauge groove 20 by clamping clamp 30, and the length of the blade battery housing 50 is checked by go / no-go gauge 40 to see if it is within the allowable tolerance range.

[0032] When using the go / no-go gauge 40 to check the length of the blade battery housing 50, such as Figure 3 As shown, the go / no-go gauge 40 has a go gauge end 400 and a no-go gauge end 401 at its two ends. The go gauge end 400 has a diameter of 2.8 mm, and the no-go gauge end 401 has a diameter of 3.2 mm. The go gauge end 400 and the no-go gauge end 401 slide along the width direction of the rectangular inspection groove 20, and the following results can be obtained intuitively: if the go gauge end 400 can completely pass through the inspection gap, and the no-go gauge end 401 cannot pass through the inspection gap, it is considered that the length of the blade battery housing 50 is within the required limit; if the go gauge end 400 cannot pass through the inspection gap, the blade battery housing 50 is a defective product with a length exceeding the upper limit; if the no-go gauge end 401 can pass through the inspection gap, the blade battery housing 50 is a defective product with a length exceeding the lower limit.

[0033] In this specific embodiment, the inner length of the rectangular gauge groove 20 is the sum of the upper limit of the length of the blade battery housing 50 and the diameter of the go gauge end 400 on the go / no-go gauge 40; for example, the length of the blade battery housing 50 is 591.8 ± 0.2 mm, and the inner length of the rectangular gauge groove 20 is the upper limit of the length of the blade battery housing 50, 591.8 mm + the diameter of the go gauge end 400, 2.8 mm.

[0034] In this specific embodiment, the inner cavity width of the rectangular gauge groove 20 is the upper limit of the width of the blade battery housing 50; the inner cavity width of the rectangular gauge groove 20 is 112mm, which is the upper limit of the width of the blade battery housing 50.

[0035] In this specific embodiment, the inner cavity dimension tolerance of the rectangular inspection slot 20 is ±0.01mm; so that the inspection tool of this application has high inspection accuracy and can effectively identify whether the length and width of the blade battery casing 50 are qualified.

[0036] In this specific embodiment, the two ends of the inspection plate 10 along its length are respectively provided with U-shaped limiting protrusions 100, and a rectangular inspection groove 20 is formed between the two U-shaped limiting protrusions 100 and the inspection plate 10; a strip-shaped middle protrusion 101 is provided between the two U-shaped limiting protrusions 100, and the middle protrusion 101 is provided along the length side of the inspection plate 10, and a notch 102 is provided between the middle protrusion 101 and the limiting protrusions 100; in the design process of the inspection plate 10 of this application, the two ends of the length of the rectangular inspection groove 20 are designed with U-shaped limiting protrusions 100, and the length side is separated by a middle protrusion 101 with a notch 102, so that the inspection personnel can quickly pick up and replace the blade battery housing 50, thereby improving the inspection efficiency.

[0037] In this specific embodiment, the clamp 30 is fixedly connected to the central protrusion 101 by screws or glue; this facilitates the disassembly and use of the clamp 30. It should be understood that the clamp 30 in this application is a common and universal clamp 30 structure, which only serves to fix the blade battery housing 50 on the inspection plate 10, so as to avoid affecting the detection accuracy due to detection offset.

[0038] In this specific embodiment, the heights of the central protrusion 101, the limiting protrusion 100, and the blade battery housing 50 are consistent, satisfying the requirement of a 14mm height for the blade battery housing 50; the widths of the central protrusion 101 and the limiting protrusion 100 are consistent, and the width is not less than 6mm, ensuring the strength of the inspection plate 10.

[0039] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
