DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-3 As shown, the first embodiment of the go / no-go gauge jig for batch measuring the upper and lower limits of battery sizes of the present invention includes a base plate 8, a width measuring component, a height measuring component, and a thickness measuring component.

[0027] Furthermore, the width measuring component includes a first width upper limit plate 1, a second width upper limit plate 2, a first width lower limit block 11 and a second width lower limit block 21; the height measuring component includes a first height upper limit plate 3, a second height upper limit plate 4, a first height lower limit block 31 and a second height lower limit block 41; the thickness measuring component includes a thickness measuring bracket 6 and a thickness measuring roller 7. In this first embodiment, the first width upper limit plate 1 and the first height upper limit plate 3 are integrally formed, and the second width upper limit plate 2 and the second height upper limit plate 4 are integrally formed. The first width upper limit plate 1, the first height upper limit plate 3, the second width upper limit plate 2 and the second height upper limit plate 4 together constitute an L-shaped test channel, so that the battery 9 can be slidably tested in the L-shaped test channel.

[0028] Furthermore, the first width upper limit plate 1 and the second width upper limit plate 2 are arranged in parallel on the bottom plate 8, one end of the first width lower limit block 11 is connected to one end of the first width upper limit plate 1, and one end of the second width lower limit block 21 is connected to one end of the second width upper limit plate 2, wherein the first width upper limit plate 1 and the second width upper limit plate 2 form a first spacing, and the other end of the first width lower limit block 11 and the other end of the second width lower limit block 21 are inclined toward each other to form a second spacing, and the second spacing is smaller than the first spacing; in addition, in other embodiments, the first width lower limit block 11 can also be arranged to protrude as a whole relative to the first width upper limit plate 1, and the second width lower limit block 21 can also be arranged to protrude as a whole relative to the second width upper limit plate 2, so that the second spacing formed by the first width lower limit block 11 and the second width lower limit block 21 is smaller than the above-mentioned first spacing.

[0029] Furthermore, the first height upper limit plate 3 and the second height upper limit plate 4 are arranged in parallel on the base plate 8, one end of the first height lower limit block 31 is connected to one end of the first height upper limit plate 3, and one end of the second height lower limit block 41 is connected to one end of the second height upper limit plate 4, wherein the first height upper limit plate 3 and the second height upper limit plate 4 form a third distance, and the other end of the first height lower limit block 31 and the other end of the second height lower limit block 41 are arranged to be inclined toward each other to form a fourth distance, and the fourth distance is smaller than the third distance.

[0030] Preferably, the first width lower limit block 11 is integrally formed with the first width upper limit plate 1, the second width lower limit block 21 is integrally formed with the second width upper limit plate 2, the first height lower limit block 31 is integrally formed with the first height upper limit plate 3, and the second height lower limit block 41 is integrally formed with the second height upper limit plate 4.

[0031] In addition, the thickness measuring bracket 6 is arranged on the base plate 8, and the thickness measuring roller 7 is arranged on the thickness measuring bracket 6 and is located above the base plate 8. Furthermore, in this first embodiment, the thickness measuring roller 7 is located above the first spacing; in other embodiments, the thickness measuring roller 7 can also be arranged above the third spacing or other positions, and no excessive restrictions are imposed here.

[0032] It can be understood that when testing the dimensions of a product such as battery 9, the first spacing is used to measure the upper limit of the width of battery 9, and the second spacing is used to measure the lower limit of the width of battery 9. When the width of battery 9 needs to be measured to see if it is acceptable, if the battery 9 can pass through the first spacing, it indicates that the width of battery 9 does not exceed the upper limit of the width of an acceptable battery (if it cannot pass through the first spacing, it indicates that the width of battery 9 exceeds the upper limit of the width of an acceptable battery). In addition, if the battery cannot pass through the second spacing, it indicates that the width of the battery meets the lower limit of the width requirement, i.e., it is greater than the lower limit of the width. In other words, if the battery can pass through the first spacing but not the second spacing, it indicates that the width of the battery meets the width requirement. Similarly, the third spacing is used to measure the upper limit of the height of battery 9, and the fourth spacing is used to measure the lower limit of the height of battery 9. If the battery 9 can pass through the third spacing but not the fourth spacing, it indicates that the height of the battery meets the height requirement. In addition, the spacing between thickness measuring roller 7 and base plate 8 corresponds to the upper limit of the thickness of battery 9. If the battery 9 can pass through thickness measuring roller 7, it indicates that the thickness of the battery does not exceed the upper limit of the thickness of an acceptable battery.

[0033] In addition, if Figure 4-6 As shown, the difference between the second embodiment of the go / no-go gauge jig for batch measuring the upper and lower limits of battery sizes and the above-mentioned first embodiment is that: the above-mentioned first embodiment is a go / no-go gauge jig of fixed size, that is, the first spacing, the second spacing, the third spacing, the fourth spacing, and the spacing between the thickness measuring roller 7 and the base plate 8 are all fixed and cannot be adjusted. The go / no-go gauge jig of fixed size is suitable for use in batch production of large models, and does not need to be adjusted to be dedicated to the battery size measurement of a certain model, which is conducive to long-term use; while the second embodiment is a go / no-go gauge jig with adjustable size, that is, the first spacing, the second spacing, the third spacing, the fourth spacing, and the spacing between the thickness measuring roller 7 and the base plate 8 are all adjustable sizes. The go / no-go gauge jig with adjustable size is suitable for frequent adjustment during the production of multiple models, which is conducive to replacing different battery models for size measurement in a short time.

[0034] In the second embodiment, the first width lower limit block 11 is integrally formed with the first width upper limit plate 1, the second width lower limit block 21 is integrally formed with the second width upper limit plate 2, the first height lower limit block 31 is integrally formed with the first height upper limit plate 3, and the second height lower limit block 41 is integrally formed with the second height upper limit plate 4; the second width lower limit block 21 and the second width upper limit plate 2 are fixedly arranged on the bottom plate 8, the first height lower limit block 31 and the first height upper limit plate 3 are fixedly arranged on the bottom plate 8, the first width lower limit block 11 and the first width upper limit plate 1 can be movably arranged on the bottom plate 8 left and right, and the second height lower limit block 41 and the second height upper limit plate 4 can be movably arranged on the bottom plate 8 forward and backward; the thickness measuring roller 7 is movably arranged on the thickness measuring bracket 6 up and down. It should be understood that the positions of the first width lower limit block 11 and the first width upper limit plate 1 can be moved left and right according to the width size of the battery 9, so that the first spacing and the second spacing are increased or decreased to better meet the measurement requirements of different width upper limits and width lower limits of different batteries; similarly, by moving the second height lower limit block 41 and the second height upper limit plate 4 forward and backward to adjust the size of the third spacing and the fourth spacing, the height size measurement requirements of different batteries can be met; by moving the thickness measuring roller 7 up and down, the thickness size measurement requirements of different batteries can be met.

[0035] Furthermore, the base plate 8 is provided with a plurality of first screw holes 5 spaced apart along the left-right direction. The first width upper limit plate 1 and the first width lower limit block 11 are both provided with first through holes 51 extending through their upper and lower end surfaces. The first width upper limit plate 1 and the first width lower limit block 11 are fixed to the base plate 8 by first screws passing through the first through holes 51 and connected to the first screw holes 5. When the first spacing and the second spacing need to be adjusted, the first screws are loosened to align the first through holes 51 with the first screw holes 5 at other positions, and finally the first screws are tightened again to adjust the first spacing and the second spacing. Similarly, the second height lower limit block 41 and the second height upper limit plate 4 can also be connected in the same manner as the first screw holes 5 and the first through holes 51 described above to achieve a forward and backward movable arrangement on the base plate 8. Of course, other movable connection methods of the prior art can also be used to achieve the movable arrangement of the first width lower limit block 11, the first width upper limit plate 1, the second height lower limit block 41, and the second height upper limit plate 4, and no excessive restrictions are imposed here.

[0036] Furthermore, a vertical slot 61 is provided in the thickness measuring bracket 6, and a slider 71 is provided at the end of the thickness measuring roller 7. The slider 71 is located in the vertical slot 61, and the vertical slot 61 is provided with a second through hole 611. The slider 71 is provided with a second screw hole 711. A second screw passes through the second through hole 611 and is connected to the second screw hole 711 to fix the slider 71 in the vertical slot 61. When the upper limit of the thickness of different batteries needs to be measured, the second screw is loosened to adjust the position of the slider 71 in the vertical slot 61, and finally the second screw is tightened again to adjust the spacing between the thickness measuring roller 7 and the base plate 8. In other embodiments, a third through hole can be provided in the side wall of the slider 71, and multiple fourth through holes can be provided in the upper and lower side walls of the thickness measuring bracket 6. The thickness measuring roller 7 can be moved up and down by using other movable connection methods in the prior art, such as a latch to engage the third through hole and the fourth through hole. No excessive restrictions are imposed here.
