Description
Technical Field
[0001] The utility model relates to the technical field of new energy battery equipment, in particular to a new energy battery shell measuring tool. Background Art
[0002] The new energy battery shell is an important component of new energy batteries. It is very important to measure the new energy battery shell before it leaves the factory.
[0003] In the prior art, a vernier caliper, also known as caliper for short, is usually used, and two workers are assigned to measure the width of the battery shell. During measurement, the two jaws of the vernier caliper are in line contact with the surface of the battery shell, which easily causes the jaws to form an angle with the width direction of the battery shell, thereby causing the measured value to be larger than the actual width of the battery shell. In order to avoid this situation, during measurement, the two jaws of the caliper are usually moved in opposite directions, and the moving direction is always parallel to the length direction of the battery shell. In the process of moving the two jaws of the caliper, the minimum value measured by the vernier caliper is read, which is the actual width of the battery shell. However, since the vernier caliper is made of metal, its surface hardness is greater than the hardness of the battery shell. In the process of moving the jaws of the caliper, the surface of the battery shell is easily scratched, thereby damaging the appearance of the product.
[0004] That is, in the prior art, a vernier caliper is used to measure the width of a battery shell. If the caliper is not moved along the length direction of the battery shell during measurement, the measured result is larger than the actual result of the width of the battery shell. If the caliper is moved along the length direction of the battery shell, the surface of the battery shell is easily scratched.
[0005] In summary, the problem existing in the prior art is the lack of a new energy battery shell measuring tool that can accurately measure the value of the battery shell width without scratching the surface of the battery shell. Utility Model Content

[0033] Example 1
[0034] like Figure 1-2 As shown, this embodiment proposes a new energy battery shell measuring tool, which includes a bracket 1 with an anti-wear layer on the outer surface, wherein the hardness of the anti-wear layer is configured to be a preset hardness, and the bracket 1 has a first plane 2; it also includes a protrusion 3 and a dial indicator 4, the dial indicator 4 is arranged on the bracket 1 through the protrusion 3, and the distance between the test end of the dial indicator 4 and the first plane 2 along the direction indicated by the first straight line can be configured to be a preset distance.
[0035] The shape of the bracket 1 matches the product to be tested. For example, it can be processed into a contoured part. In this embodiment, the battery shell is generally rectangular. The bracket 1 is used to span the battery shell along the width direction of the battery shell when measuring the width of the new energy battery shell. The material of the bracket 1 is cold-rolled steel, and an anti-wear layer is provided on the outer surface of the bracket 1. In this embodiment, the anti-wear layer is formed by particle spraying, and the hardness of the anti-wear layer is configured to a preset hardness. The preset hardness of the anti-wear layer should be equal to or less than the surface hardness of the product to be tested, that is, the battery shell; preferably, the preset hardness is equal to the surface hardness of the battery shell.
[0036] Specifically, the bracket 1 of this embodiment includes the following structure: the bracket 1 includes a first plate 5, a second plate 6 and a third plate 7, preferably, the first plate 5, the second plate 6 and the third plate 7 are all rectangular plates; wherein, the first plate 5 and the second plate 6 are parallel to each other and perpendicular to the third plate 7 respectively, and the first plate 5 and the second plate 6 are connected by the third plate 7; the first plane 2 is a side plate surface of the first plate 5 facing the second plate 6; the protrusion 3 is connected to the second plate 6; a clearance hole 8 is provided on the second plate 6, and the hole center line of the clearance hole 8 is parallel to the first straight line, the main body of the dial gauge 4 is connected to the protrusion 3, and the test end of the dial gauge 4 penetrates the clearance hole 8 and is located between the first plate 5 and the second plate 6. It is worth noting that the distance between the first plate 5 and the second plate 6 should be greater than the width dimension of the battery shell to be tested, otherwise it cannot be straddled on the battery shell along the width direction of the battery shell.
[0037] The structure and working principle of the dial indicator 4 are prior art and will not be elaborated here. In the present embodiment, in order to facilitate the reading of the staff, the dial indicator is an electronic digital display dial indicator, which can measure the positive and negative tolerances relative to the reference size. Usually, the preset distance between the test end of the dial indicator 4 and the first plane 2 is the zeroing reference of the dial indicator, and the zeroing can be performed by a zeroing block, such as a 650mm zeroing block. The dial indicator after zeroing can be used to measure whether the new energy battery shell is within the tolerance range. For example, the qualified range of the tolerance is ±0.8mm, that is, using the new energy battery shell measuring tool, measure whether the new energy battery shell is within the size range of 650mm±0.8mm. Of course, in other optional embodiments, the preset distance can also be configured to other values depending on the size of the inspected component, which will not be elaborated here.
[0038] The protrusion 3 is preferably in the shape of a thin plate, and its structure will be described in detail below.
[0039] The new energy battery shell is referred to as the battery shell in the following text. The following is a detailed introduction to the method of using the new energy battery shell measuring tool of this embodiment to measure whether the width of the battery shell is within the range of 650mm±0.8mm:
[0040] 1. Use the zeroing block to reset the dial indicator to zero. The zeroing block is a long strip-shaped block with a length of 650mm±0.02;
[0041] 2. Along the width direction of the battery shell, the bracket 1 is placed across the battery shell, and the first plane 2 is in contact with one side outer surface of the battery shell, and the test end of the dial gauge 4 is in contact with the other side outer surface of the battery shell, that is, along the width direction of the battery shell, the battery shell is located between the first plane 2 and the test end of the dial gauge 4;
[0042] 3. Move the first plate and the second plate forward and backward along the length direction of the battery shell. It is worth noting that the moving direction of the first plate is opposite to that of the second plate. For example, the first plate moves toward the second direction, and the second plate moves toward the third direction. Both the second direction and the third direction are along the length direction of the battery shell, and the second direction is opposite to the third direction. The purpose of this is to prevent the third plate from having an angle with the width direction of the battery shell, which causes the reading to be larger than the actual result. In the process of moving the first plate and the second plate forward and backward, the minimum value of the reading of the dial indicator is the actual width value of the battery shell.
[0043] 4. Measure the bottom width, waist width and top width of the battery shell in turn according to the above steps. If the bottom width, waist width and top width are all qualified, that is, they are all within the range of 650mm±0.8mm, it means that the width dimension of the battery shell is within the qualified range; if it is unqualified, it will be reworked or directly scrapped.
[0044] As can be seen from the background technology, the problem existing in the prior art is the lack of a new energy battery shell measuring tool that can accurately measure the value of the battery shell width without scratching the surface of the battery shell.
[0045] In this embodiment, a new energy battery shell measuring tool is proposed, which is composed of structures such as a bracket and a dial indicator. On the one hand, through the combination of the bracket and the dial indicator, the accurate value of the width of the battery shell can be measured. On the other hand, in this embodiment, the bracket is in contact with the outer surface of the battery shell through the anti-wear layer, and the hardness of the anti-wear layer is consistent with the hardness of the outer surface of the battery shell, or even smaller. Therefore, when using the new energy battery shell measuring tool of this embodiment, in the process of measuring the width of the battery shell, even if the bracket is moved to obtain the minimum value of the dial indicator reading, that is, the accurate value of the width of the battery shell, the bracket will not scratch the outer surface of the battery shell; in summary, this embodiment solves the problems existing in the prior art: there is a lack of a new energy battery shell measuring tool that can accurately measure the value of the width of the battery shell without scratching the surface of the battery shell.
[0046] like Figure 2-Figure 3 As shown, further, this embodiment also includes the following technical solutions. A new energy battery shell measuring tool of this embodiment also includes a contact component 9, and the contact component 9 is detachably connected to the test end of the dial indicator 4. The contact component 9 is provided with a second plane 10 on the side facing the first plate 5, and the second plane 10 is parallel to the first plane 2. Preferably, the contact component 9 is threadedly connected to the test end of the dial indicator 4. Preferably, the contact component 9 can be configured into a variety of specifications according to actual conditions, which is not limited here.
[0047] It can be seen from the foregoing that the first plane 2 is in contact with the outer surface of one side of the battery shell, and the cylindrical test end of the dial gauge 4 is in contact with the outer surface of the other side of the battery shell. Usually, when the cylindrical test end is in vertical contact with the surface of the battery shell, the measured result is an accurate result; and the general dial gauge 4, the end face of its cylindrical test end is provided with a hemispherical contact surface, and the cylindrical test end is in contact with the battery shell through the hemispherical contact surface, which causes the test end of the dial gauge to be in line contact or point contact with the outer surface of the battery shell, that is, the contact area between the test end of the dial gauge and the outer surface of the battery shell is too small, which easily causes the cylindrical test end of the dial gauge to roll on the surface of the battery shell through the hemispherical contact surface, resulting in an angle between the cylindrical test end and the width direction of the battery shell, thereby causing the measurement data of the dial gauge to be inaccurate; therefore, the next technical problem to be solved is how to increase the contact area between the test end of the dial gauge and the outer surface of the battery shell so that the test end of the dial gauge and the outer surface of the battery shell are in surface-to-surface contact.
[0048] In the present embodiment, a contact component 9 is connected to the test end of the dial indicator 4, and a second plane 10 is provided on the contact component 9, that is, the test end of the dial indicator contacts with one side surface of the motor housing through the second plane 10; therefore, the present embodiment also solves the technical problem of how to increase the contact area between the test end of the dial indicator and the outer surface of the battery housing. The present embodiment enables the test end of the dial indicator to be in surface-to-surface contact with the outer surface of the battery housing.
[0049] Furthermore, in the present embodiment, the second plane 10 is parallel to the first plane 2, so that after the bracket 1 is straddled on the battery shell, along the width direction of the battery shell, the first plane 2 contacts one of the outer surfaces of the battery shell, and the second plane 10 contacts the other outer surface of the battery shell. Along the width direction of the battery shell, the battery shell is confined between the first plane 2 and the second plane 10, and the battery shell forms surface-to-surface contact with the first plane 2 and the second plane 10, respectively.
[0050] like Figure 2 to Figure 4 As shown, further, this embodiment also includes the following technical solutions: the new energy battery shell measuring tool also includes a base 11, the base 11 is arranged on the protrusion 3, the shape of the base 11 is consistent with the shape of the back cover of the dial indicator 4, and the dial indicator 4 is connected to the base 11.
[0051] In this embodiment, the shape of the base 11 is configured to be consistent with the shape of the back cover of the dial indicator 4 to which it is to be connected. During installation, the back cover of the dial indicator 4 can be directly removed, and the base 11 can be used as the back cover of the dial indicator 4 and connected to the dial indicator. This avoids re-drilling on the back of the dial indicator 4, and installation is more convenient and quick.
[0052] Furthermore, it is mentioned in the foregoing that the detachable connecting contact member 9 at the test end of the dial gauge 4 will cause the distance between the second plane 10 of the contact member 9 and the first plane 2 to be less than the preset distance, which will further result in that if the battery shell of the original size is to be measured, the bracket cannot be placed across the battery shell during measurement; therefore, the present embodiment also includes the following technical solutions:
[0053] like Figure 2 to Figure 5 As shown, the base 11 is provided with a first sliding part 12, the protruding part 3 is provided with a second sliding part 13, the first sliding part 12 and the second sliding part 13 form a sliding pair along the first straight line; and further includes a locking member 14, the locking member 14 is provided on the first sliding part 12, and the locking member 14 is used to lock the first sliding part 12 and the second sliding part 13 after sliding. Further, preferably, the first sliding part 12 is a screw; the second sliding part 13 is a strip hole, the strip hole extends along the first straight line; the locking member 14 is a nut.
[0054] In this embodiment, the base 11 can slide on the protrusion 3 along the first straight line. When the base 11 reaches the specified position, the locking member 14 is used to lock the base 11 on the protrusion 3; in this embodiment, the friction between the base 11 and the protrusion 3 is increased by screwing a nut into a screw rod, so that the base 11 is temporarily locked on the protrusion 3. When adjustment is required next time, the nut can be screwed out of the screw rod; the specified position mentioned in the above content is the position corresponding to the preset distance so that the distance between the first plane 2 and the second plane 10 meets the preset distance; and thus, this embodiment can ensure that, even if a contact component 9 is provided at the test end of the dial indicator 4, the position of the base 11 along the first straight line on the protrusion 3 can be adjusted to ensure that the distance between the first plane 2 and the second plane 10 meets the preset distance.
[0055] like Figure 2-Figure 3 As shown, further, a new energy battery shell measuring tool of the present embodiment is characterized in that a plurality of de-weighting holes are arranged on the bracket 1; the de-weighting holes are formed by removing part of the material of the bracket 1, and the purpose of setting the de-weighting holes is to reduce the overall weight of the new energy battery shell measuring tool and facilitate the operator to pick up and move it. The new energy battery shell measuring tool of the present embodiment is light in weight and simple to operate. It can be operated by only one worker to complete all the measurement steps. Compared with the method of using caliper measurement in the prior art which requires two workers, the present embodiment saves more labor costs.
[0056] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
