Abstract
The invention discloses a rotation indexing type drill plate. The rotation indexing type drill plate is in a circular ring shape. Two symmetrically-arranged grooves are formed in one center line of the edge of the rotation indexing type drill plate, and 12 holes are evenly formed in the rotation indexing type drill plate. The connecting lines between the holes close to the grooves and the circle center of the rotation indexing type drill plate are ab, and the included angle between ab and the center line where the grooves are formed is 7 degrees. An annular boss concentric with the rotation indexing type drill plate is arranged on the rotation indexing type drill plate, and an inclined 45-degree tool withdrawal groove is formed in the connecting position of the annular boss and the rotation indexing type drill plate. The rotation indexing type drill plate is simple in design structure, convenient to manufacture, low in machining cost and convenient to use, production efficiency is improved, and labor cost is reduced.
Description
Technical field
The application relates to a kind of bushing plate, is specially a kind of circular index formula bushing plate, belongs to machining technique field.
Background technology
Spring holder is the stand of support spring on shock absorber, and on spring holder, the lift of spiral must be consistent with the spiral lift of spring, otherwise just likely causes spring to cause abnormal sound after entrucking.But because of each vehicle spring spiral lift difference, so the spring holder coordinated with spring also causes shape, height exists very big-difference.Shock absorber manufacturer is when producing shock absorber now, screw is mainly mixed by boring several screwed hole on a flat board in the welding location of its spring holder, height according to the height adjustment screw of spring holder spiral lift is located, process lift to locate with the lift Linear cut mode according to spring, the shortcoming of these two kinds of modes is: because screw and spring holder can only point cantact during first kind of way location, so mating surface less location shakiness; During adjustment, spring holder belongs to stamping parts, and individual difference is comparatively large, so positional accuracy is not high and governing speed is comparatively slow, welding deformation is large.In addition, if the more flat board need processing a lot of hold-down screw of product category, so cost is higher, second way location is mainly to pass through Linear cut, cost expenses is larger, spring holder belongs to stamping parts, individual difference is larger, can only not match likely to have with actual parts by theoretical value machining during Linear cut, also location may be caused unstable, the frock of two kinds of localization methods all needs to install compression facility additional, the limited words of welding equipment as excessive in spring holder easily produce that compression tooling interferences with equipment may, thus have larger requirement to welding equipment.
Such as application number is 200910167745.6, denomination of invention is the patent of locating tooling for forming moulding bed, it discloses a kind of locating tooling for forming moulding bed, comprise fuel tank, this frock is made up of spring holder and die body, die body there are endoporus and several apertures built with magnetic material, die body is by the specification of spring holder, the characteristic utilizing zinc ingot metal easily to melt carries out material object casting, bottom die body, strong magnets is housed, by the suction of magnet, spring holder is adsorbed on die body firmly, because die body gets according to spring holder profile straight forming, therefore, it is possible to ensure spring holder laminating to greatest extent closely, ensure that welding precision, and compression facility can be cancelled, and special requirement is not had to welding equipment, easy to use, cost-saving.
Such as application number is 200820172848.2 again, denomination of invention is processing bracket revolution drill jig, comprise a discoidal drill jig base plate and be used for carrying the turntable of drill jig base plate, turntable is provided with gyrator, gyrator is coaxially connected with a fixed axis, drill jig base plate has a locating surface, locating surface is provided with the alignment pin and several bushing plates that position processing work, because on revolution drill jig, match with the working position of workpiece to be machined in the position of bushing plate, the number of degrees rotated when gyrator rotates at every turn are identical with the angle between bushing plate, make workpiece to need the position of boring corresponding with drill bit, this processing method needs to switch back and forth, repeat fixation workpiece, complex process, add the labour intensity of workman, reduce production efficiency, again because repeatedly switch back and forth, repeat fixation workpiece, resetting, reduce machining accuracy.
