Description

Technical Field

[0001] This utility model relates to the field of battery casing inspection technology, and in particular to a tooling fixture for detecting the surface bulge of a battery casing. Background Technology

[0002] When a bulge appears on the surface of the battery casing, the location of the bulge is detected in order to ensure that the expansion is within the allowable range. However, it is difficult to accurately judge the size of the expansion by visual observation during the detection process. This can easily lead to misjudgment and cause unusable battery casings to continue to be used. Utility Model Content

[0003] The main purpose of this invention is to provide a tooling fixture for detecting the bulging degree of the battery casing surface, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fixture for detecting the surface bulge of a battery casing includes a detection plate, a slider, screws, and a fastening sleeve. The slider is mounted on the front surface of the detection plate, and screws are embedded inside the slider and near both sides. A fastening sleeve is threaded onto the surface of the screws and located behind the detection plate.

[0005] More preferably, the detection plate includes an integrally connected long plate and a short plate, both of which have sliding openings on their surfaces, and the detection plate is L-shaped.

[0006] More preferably, the slider has through holes on its surface and near both sides, and the screw passes through the through holes and the sliding opening.

[0007] Compared with the prior art, this utility model proposes a tooling fixture for detecting the bulging degree of battery casing surface, which has the following beneficial effects: In this invention, by setting up a detection plate, a slider, screws, and a fastening sleeve in cooperation, when detecting the expansion area on the surface of the battery casing, the detection plate is attached to the surface of the battery casing, and then a digital vernier caliper is placed between the slider and the detection plate. Then, the fastening sleeve is rotated so that the slider clamps the vertically placed digital vernier caliper between the slider and the detection plate. Then, by moving the slider, the slider drives the digital vernier caliper to move. The digital vernier caliper displays the height of the expansion area by contacting it. This allows for convenient and accurate measurement of the expansion height. Attached Figure Description

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0012] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] like Figure 1-4 As shown, a tooling fixture for detecting the bulging of a battery casing surface includes a detection plate 1, a slider 2, screws 3, and a fastening sleeve 4. The slider 2 is mounted on the front surface of the detection plate 1, and screws 3 are embedded inside the slider 2 and near both sides. The fastening sleeve 4 is threaded onto the surface of the screws 3 and located behind the detection plate 1.

[0014] In the above structure, when the rotating fastening sleeve 4 causes the slider 2 to clamp the digital display vernier caliper between the slider 2 and the detection plate 1, the screw 3 is first limited to prevent it from rotating when the fastening sleeve 4 is rotated.

[0015] In a preferred embodiment, the detection plate 1 includes an integrally connected long plate 101 and a short plate 102, and both the long plate 101 and the short plate 102 have sliding openings 103 on their surfaces. The detection plate 1 is L-shaped.

[0016] In a preferred embodiment, the slider 2 has through holes 201 on its surface and near both sides, and the screw 3 passes through the through holes 201 and the sliding opening 103.

[0017] In the above structure, the part of the screw 3 that passes through the sliding opening 103 contacts the sliding opening 103, thus preventing the slider 2 from moving up and down when it moves.

[0018] When using this invention to detect the expansion point on the surface of the battery casing, the detection plate 1 is attached to the surface of the battery casing, and then a digital vernier caliper is placed between the slider 2 and the detection plate 1. Then, the fastening sleeve 4 is rotated so that the slider 2 clamps the vertically placed digital vernier caliper between the slider 2 and the detection plate 1. The lower end of the vertically placed vernier caliper contacts the normal surface of the battery casing. Then, by moving the slider 2, the digital vernier caliper is moved. The digital vernier caliper displays the height of the expansion point by contacting it, which allows for convenient and accurate measurement of the expansion height.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
