two pairs of free rotary parts mounted at upper angular points of the hinge part, the free rotary parts being disposed at the upper plate in a line contact fashion,
wherein a lower end of the height adjustment unit is fixedly disposed above the lower plate, an upper end of the height adjustment unit is disposed at the lower end of the upper plate in a line contact fashion, and the height adjustment unit adjusts vertical height and horizontal deflection of the upper plate at the line contact portion.
2. The device for adjusting vertical height and horizontal deflection according to claim 1 , wherein one or more variable posts are mounted around the height adjustment unit at each side of the height adjustment unit.
3. The device for adjusting vertical height and horizontal deflection according to claim 1 , wherein each variable post further comprises a fixing part for fixing height of a corresponding portion of the upper plate changed by the height adjustment unit.
4. The device for adjusting vertical height and horizontal deflection according to claim 3 , wherein the fixing part is a clamp lock mounted to a lower end of a corresponding one of the variable posts adjacent to the lower plate.
5. The device for adjusting vertical height and horizontal deflection according to claim 1 , wherein the eccentric cam is configured to have a structure including a follower link, bearings, and a shaft.
6. The device for adjusting vertical height and horizontal deflection according to claim 1 , wherein a driving handle is further mounted at the eccentric cam.
7. The device for adjusting vertical height and horizontal deflection according to claim 6 , wherein the driving handle is connected to a shaft of the eccentric cam via a worm and a worm gear.
8. The device for adjusting vertical height and horizontal deflection according to claim 7 , wherein, when the shaft of the eccentric cam makes one rotation, the driving handle makes more than one rotation.
9. The device for adjusting vertical height and horizontal deflection according to claim 1 , wherein each free rotary part comprises a pair of bearings disposed at the lower end of the upper plate in a contact fashion and a shaft for connecting the bearings to the upper angular points of the hinge part.
10. The device for adjusting vertical height and horizontal deflection according to claim 1 , further comprising one or more gauges mounted at opposite sides of the height adjustment unit to indicate height of the upper plate at portions at which the gauges are mounted.
11. The device for adjusting vertical height and horizontal deflection according to claim 10 , wherein two gauges are mounted around the height adjustment unit at the opposite sides of the height adjustment unit.
12. The device for adjusting vertical height and horizontal deflection according to claim 1 , wherein a variable post (PL) and a gauge (GL) are located at a left side of the height adjustment unit and a variable post (PR) and a gauge (GR) are located at a right side of the height adjustment unit.
13. The device for adjusting vertical height and horizontal deflection according to claim 12 , wherein, in a case in which it is necessary to change a height (Hp) of the upper plate to a set height (Ha) without horizontal deflection, the height adjustment unit is adjusted to change height of the variable post (PL) such that height indicated by the gauge (GL) becomes the set height (Ha) and then the variable post (PL) is fixed and, subsequently, the height adjustment unit is adjusted again to change height of the variable post (PR) such that height indicated by the gauge (GR) becomes the set height (Ha) and then the variable post (PR) is fixed.
14. The device for adjusting vertical height and horizontal deflection according to claim 10 , wherein each gauge is a dial gauge.
15. The device for adjusting vertical height and horizontal deflection according to claim 10 , wherein a lower end of each gauge is fixed to the upper plate and a load unit is connected to the lower plate.
16. The device for adjusting vertical height and horizontal deflection according to claim 1 , further comprising:
a beading device loaded at a top of an upper plate of the device for adjusting vertical height and horizontal deflection to fix beading of a cylindrical battery.
17. A method of manufacturing a cylindrical battery, the method comprising:
using the device for adjusting vertical height and horizontal deflection according to claim 16 to fix beading of the cylindrical battery.
