[0002] During the production process of batteries, it is necessary to use battery charging and discharging equipment to charge and discharge the batteries to realize the formation and grading of the batteries and activate the batteries. At present, to ensure that the voltage and current accuracy of the battery charging and discharging equipment meet the requirements, the charging and discharging equipment usually needs to be calibrated regularly, and most of them use calibration tooling to calibrate the charging and discharging equipment. Specifically, first, the calibration tooling is manually installed on the charging and discharging bin position, then the power supply of the calibration tooling and the communication line between it and the charging and discharging equipment are connected, and finally the calibration work can be carried out.

[0003] However, the distance between the positive electrode plate and the negative electrode plate on the existing power measurement calibration tooling cannot be changed, and only batteries of a single size can be used for calibration work. Since the battery sizes of each manufacturer are not unified and the distances between the positive and negative electrodes of the batteries are also different, the current power measurement calibration tooling cannot be used to calibrate batteries of different sizes, and the compatibility is poor. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a power measurement calibration tooling, aiming to effectively solve the problem of non-uniform battery sizes of each manufacturer and improve the compatibility of the power measurement calibration tooling with batteries of different sizes.

[0009] In one embodiment, the moving plate assembly includes a moving plate fixedly connected to the adjusting block, a pole piece adjusting rod disposed on the moving plate, and a plurality of pole piece mounting blocks disposed on the pole piece adjusting rod. The moving plate is slidably connected to the guide rail, and the pole piece mounting blocks are used for mounting the positive pole piece or the negative pole piece.

[0010] In one embodiment, fixing blocks are fixedly connected to both ends of the pole piece adjusting rod. Fixing holes are formed through the fixing blocks, and a plurality of adjusting holes are formed in the moving plate. Screws can pass through the fixing holes and be screwed into the adjusting holes to fix the pole piece adjusting rod to the moving plate.

[0011] In one embodiment, a sliding groove is provided on the pole piece adjusting rod, and the pole piece mounting blocks are slidably mounted in the sliding groove.

[0012] In one embodiment, both ends of the plurality of guide rails are respectively connected by two support rods.

[0018] Compared with the prior art, when it is necessary to increase the distance between the positive electrode plate and the negative electrode plate in the technical solution of the present utility model, the adjusting screw is rotated clockwise so that the adjusting block drives the moving plate assembly to move outward, and then the adjusting screw on the other side is rotated clockwise so that the adjusting block on the other side also drives the moving plate assembly to move outward, so that the distance between the positive electrode plate and the negative electrode plate can be adjusted to be the same as the length of the battery to be measured. After the adjustment is completed, the needle bed probe is driven to contact the positive electrode plate and the negative electrode plate to measure the current and voltage, and then calibration is carried out.

A plurality of positive plates 310 are provided on one of the moving plate assemblies 300, and a plurality of negative plates 320 are provided on the other moving plate assembly 300. The positive plates 310 and the negative plates 320 are connected to the power supply module 100 through cables; each adjusting component includes an adjusting screw 400 and an adjusting block 410. The adjusting block 410 is fixedly connected to the moving plate assembly 300 one by one. The adjusting block 410 is formed with an adjusting screw hole 411. The adjusting screw 400 is screwed into the adjusting screw hole 411. The rotation of the adjusting screw 400 can make the adjusting block 410 drive the moving plate assembly 300 to move, so that the distance between the positive plates 310 and the negative plates 320 can be adjusted.

[0028] Specifically, two moving plate assemblies 300 are respectively arranged on both sides of the power module 100. The power module 100 also includes an electronic component such as a switching board, a main control board, a transformer, a multimeter for detecting the current and voltage between the positive electrode plate 310 and the negative electrode plate 320, and a Hall sensor. The positive electrode plate 310 and the negative electrode plate 320 can be connected to the switching board inside the power device through cables. The housing of the power device can be preset with holes for the cables of the positive electrode plate 310 and the negative electrode plate 320 to pass through and connect to the switching board. During use, the power measurement calibration tooling is installed on the charging and discharging bin position. After adjustment, the power supply of the power measurement calibration tooling and its communication line with the charging and discharging equipment are connected. The probe on the charging and discharging equipment is driven to contact the positive electrode plate 310 and the negative electrode plate 320, and finally the calibration work is carried out. In the present utility model, along the straight line parallel to the length direction of the adjusting screw rod 400, the distance between the positive electrode plate 310 and the negative electrode plate 320 represents the length of a battery. When it is necessary to adapt to batteries of different sizes, the adjusting screw rod 400 can be rotated to drive the adjusting block 410 threadedly connected thereto to move, thereby causing the moving plate assembly 300 to move, so that the distance between the positive electrode plate 310 and the negative electrode plate 320 is equal to the length of the battery. For example: when it is necessary to increase the distance between the positive electrode plate 310 and the negative electrode plate 320, the adjusting screw rod 400 is rotated clockwise to cause the adjusting block 410 to drive the moving plate assembly 300 provided with the positive electrode plate 310 to move outward, and then the adjusting screw rod 400 on the other side is rotated clockwise to cause the adjusting block 410 on the other side to also drive the moving plate assembly 300 provided with the negative electrode plate 320 to move outward, so that the distance between the positive electrode plate 310 and the negative electrode plate 320 can be adjusted to be the same as the length of the battery. After the adjustment is completed, the calibration work is carried out. With such a setting, according to the distance between the positive and negative electrodes of different batteries, the adjusting screw rod 400 can be manually adjusted to adjust the distance between the positive electrode plate 310 and the negative electrode plate 320 on the tooling, effectively solving the problem of inconsistent battery sizes of each manufacturer and improving the compatibility of the power measurement calibration tooling with batteries of different sizes.
