Abstract
The utility model discloses an automatic expansion backlash eliminating device for a slitting knife cutter shaft of a lithium ion battery. The traditional slitting knife cutter shaft mechanism is of a clearance fit design; the fit clearance of the slitting knife cutter shaft and the inner hole of the slitting knife is overlarge; circle run-out of the slitting knife is large; the slitting knife is easily abraded. The device forms an automatic expansion device, and is composed of three components which orderly are an expansion key 2, an expansion shaft 2 and an automatic expansion bag 3. Therefore, the clearance is effectively reduced; the circle run-out is reduced; the problem of a large fit clearance of the slitting knife cutter shaft and the inner hole of the slitting knife is effectively solved.
Description
Technical field
The utility model relates to a kind of lithium ion battery slitting knife cutter shaft automatic expansion backlash eliminating equipment.
Background technology
Present most of lithium ion battery slitting knife device slitting knife cutter shaft mechanism adopts the matched in clearance design, for the convenient slitting knife of installing, the endoporus fit clearance of slitting knife cutter shaft and slitting knife is large, slitting knife circle after assembling is like this beated excessive, easily causes the slitting knife wearing and tearing and produces the itemize burr.The utility model slitting knife cutter shaft automatic expansion backlash eliminating equipment is behind the assembling slitting knife, by automatic expansion, the gap between slitting knife and the cutter shaft is eliminated.Utility model has been eliminated the gap by the design backlash eliminating equipment, has reduced circle and has beated, and has improved the itemize precision, reduces consume, improves product quality.
Summary of the invention
The technical assignment of the technical problems to be solved in the utility model and proposition is the large problem of endoporus fit clearance that solves slitting knife cutter shaft and slitting knife.
The technical solution of the utility model is:
A kind of lithium ion battery slitting knife cutter shaft automatic expansion backlash eliminating equipment has increased expansion key and automatic expansion axle at conventional art.Device has 3 parts to consist of, and is successively: 1-expansion key, 2-main axis of dilatation, 3-automatic expansion capsule.Device altogether forms 4 assembly and closes with the 4-slitting knife, by B with reduce cooperating of A and G cooperating of G.
Description of drawings
Fig. 1 is the schematic diagram that comprises a kind of lithium ion battery slitting knife cutter shaft automatic expansion backlash eliminating equipment of the present utility model.
Number in the figure explanation: 1-expansion key, 2-main axis of dilatation, 3-automatic expansion capsule, 4-slitting knife, A-the first mating surface, B-the second mating surface, C-the 3rd mating surface, D-the 4th mating surface, E-the 5th mating surface, F-the 6th mating surface, G-the 7th mating surface.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further.
A kind of lithium ion battery slitting knife cutter shaft automatic expansion backlash eliminating equipment of the present utility model has 3 parts to consist of, and is successively: 1-expansion key, 2-main axis of dilatation, 3-automatic expansion capsule, 4-slitting knife.Forming 4 assembly and close, is that EF cooperates successively, and CD cooperates, and AG cooperates, and BG cooperates.By B with reduce cooperating of A and G cooperating of G, eliminated the gap, reduced circle and beated, effectively solved the large problem of endoporus fit clearance of slitting knife cutter shaft and slitting knife.
