Spring end face equipment for grinding
The utility model be related to spring processing polish technical field, and in particular to it is a kind of can be by the extra small precision of little line footpath
The equipment for grinding that both ends of the spring is polished.
It is the uniformity and preferable perpendicularity for ensureing spring heights in the manufacture of compression spring, both ends of the spring is polished
It is requisite manufacturing procedure.
The method that existing both ends of the spring is polished has two kinds, and one kind is to polish to set using the spring for being referred to as " spring grinding machine "
Standby, it is the steel mill that centre is added by upper and lower two emery wheels, and spring is positioned in the aperture on mill, is existed by mill
Rotate between two emery wheels, both ends of the spring is polished；Can see spring grinding machine, including cabinet 1 and upper lower grinding wheel 2,3 in conjunction with Fig. 1,
Upper lower grinding wheel 2,3 needs high-speed rotation, therefore emery wheel is necessarily required to certain gap 5 with host main body 4, and spring is needed in mill
By the gap 5 under 6 drive, for spring of the line footpath more than Φ more than 2.0, due to the external diameter of spring, rigidity it is relative
Than larger, gap 5 can be passed through and complete grinding.And it is even little less than Φ 2.0 for line footpath to line footpath for Φ 0.2 it is little just
For degree precision spring, they can not be driven by mill and pass through gap 5, can cause event by clamping stagnation among two gaps 5
Another kind is, by abrasive machine, to be ground near emery wheel with hand-held spring；With reference to Fig. 2 as can be seen that with holding
Spring is clearly present shortcoming in the old processing method of abrasive machine top bevel, and spring extra small first is taken incessantly, more at all with hand
Cannot ensure to be ground on the perpendicular contact emery wheel 8 of spring 7, secondly handwork is affected by human factors greatly, want for high-volume is high
For the precision spring asked, the grinding accuracy of spring and the uniformity of product cannot be ensured at all.
