Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-5, a tooling clamp for measuring the center distance of a roll core tab mainly comprises a roll core placing plate 1, an L-shaped guide groove 2, a left tab clamping groove adjusting block 4 and a right tab clamping groove adjusting block 5; the method is characterized in that: roll up one side that the core was placed board 1 and be equipped with L type guide slot 2, 2 are provided with a plurality of fixed spacing's screw hole 3 on the L type guide slot, and left utmost point ear draw-in groove adjusting block 4 and right utmost point ear draw-in groove adjusting block 5 pass through the screw fixation respectively on L type guide slot 2.
The winding core placing plate 1 is a flat plate, the winding core 7 is placed on the winding core placing plate 1, the left end of the left tab clamping groove adjusting block 4 is provided with a strip-shaped groove 10, and the right end of the left tab clamping groove adjusting block is provided with a tab clamping groove 6; the right end of the right lug clamping groove adjusting block 5 is provided with a strip-shaped groove 10, and the left end is provided with a lug clamping groove 6; the two tab clamping grooves 6 of the left tab clamping groove adjusting block 4 and the right tab clamping groove adjusting block 5 are oppositely arranged, wherein the tab clamping grooves are clamping grooves which are processed on the tab clamping groove adjusting blocks and correspond to the widths of tabs; the distance between the two tab clamping grooves 6 on the left tab clamping groove adjusting block 4 and the right tab clamping groove adjusting block 5 is adjusted according to the process requirement center distance of each battery cell.
The utility model discloses a theory of operation is: the winding core 7 that the coiling produced all can stretch out anodal ear 8 and negative pole ear 9, and the width of utmost point ear is 4MM, and the utmost point ear centre-to-centre spacing scope of technological requirement is: standard value ± 1 MM. The process requires 40 +/-1 MM of lug center distance, namely, the center distance is in 39 to 41, and the lugs are regarded as qualified. As shown in fig. 5, the center distance is in the range of 39 to 41, the corresponding MIN is 39-4-35, the corresponding MAX is 41+ 4-45, and MAX-MIN is 2-tab slot width, so that the tab slot width of the left and right tab slot adjusting blocks can be calculated to be 5 MM. The method is popularized to the center distance of winding cores of other models, 4 to MIN value is subtracted from the lower limit of the range according to the center distance range given by process requirements, the calculated MIN value is adjusted to the distance value between the inner sides of the lug clamping grooves of the left lug clamping groove adjusting block and the right lug clamping groove adjusting block, the left lug clamping groove adjusting block and the right lug clamping groove adjusting block are fixed on the L-shaped guide groove 2 through screws, and the clamp is adjusted completely.
