Description
Technical field:
Employed skive ring flange insulation is relevant with conductive structure in the utility model and galvanic corrosion, the EDM Grinding.
Background technology:
One of mode that hard material, superhard material Precision Machining are used always is to use diamond wheel grinding, for raising the efficiency, can power up grinding; For the skive plunge grinding, the finishing of skive itself is the general difficult problem of industry, and it solves one of countermeasure is to power up under the situation to repair with diamond roller.This two all need adopt special grinding wheel flange--, this flange can realize that emery wheel is charged so that improve grinding efficiency to workpiece, simultaneously flange taper hole position again with the emery wheel insulation, with the potential difference that needs between protection machine tool chief axis and formation and workpiece.
The different designs of grinding wheel flange insulation link makes super hard abrasive (as diamond) emery wheel installation accuracy difference big, initial trim amount size changes with installation accuracy, if flange arrangement makes the emery wheel installation accuracy low, further increased difficulty and trim amount for this difficult finishing and shaping skive.
Emery wheel insulating flange dish comprises four parts: the conduction link, the insulation link, emery wheel fixing link, cooperate fixing link with main shaft, become integral (type) flange through certain design and connected mode.
Fig. 1 is insulating flange dish structure commonly used, and 3 is conducting ring; 5 is insulating barrier, and the ambroin cover adds adhesive and was cured as the common structure mode through 24 hours; 6 is the emery wheel fixing body, and B is indicated when installing for emery wheel axially and radial location face; 7 steel core bodys for the band taper hole; Connect fastening 3 and 6 with screw 1, cone 7,6,5 is by pouring into or smear the bonding and curing back formation insulating flange dish of adhesive material; Its intensity depends on and the intensity at glued place that precision then depends on the stochastic regime after the curing, and quiet, the dynamic accuracy of emery wheel depend on bonding quality, and the mutual alignment precision has randomness between member, uses but can repeat assembling; Serviceability temperature is lower.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, and is easy to use, and insulation is reliable, the reliable charged grinding of precision and intensity stabilization skive insulating flange dish.
The utility model is achieved in that
The charged grinding of the utility model skive insulating flange dish, conducting ring 3 is connected with emery wheel fixing body 6, between the periphery of the inner hole surface of emery wheel fixing body 6 and core body 7 insulating part is arranged, it is characterized in that insulating part is independently the 1st, 2 insulating parts, the 1st insulating part 5 is the cylindrical shell that an end has the 1st ring flange, be the mounting disc of conducting ring 3 between the 2nd ring flange of the 1st ring flange and emery wheel fixing body 6, porose on the 2nd ring flange, the 2nd insulating part 4 is some independently packing rings, core body 7 have the 3rd ring flange to be connected with the machine tool chief axis link with the 1st ring flange of the 1st insulating part, some screws 1 pass the 2nd insulating part 4 successively, the 3rd ring flange, hole on the 1st ring flange is threaded with emery wheel fixing body 6 through the centre bore of conducting ring mounting disc.
The endoporus interference fits of the cylindrical of the 1st insulating part 5 and emery wheel fixing body 6, the cylindrical interference fits of the endoporus of the 1st insulating part 5 and core body 7.
1st, 2 insulating parts are made with fiber-reinforced plastic.
The utility model is by being assembled into emery wheel insulating flange dish to the permanent mode of tightening up of employing screw between radial and axial location, insulating part and steel emery wheel fixing body, insulating part and the conducting ring of grinding wheel flange dish insulating part, insulating part adopts fiber-reinforced plastic, the insulating flange structure is firm, mechanical mechanics property near the integrated steel flange, can bear the above operating current of 200A (ampere), the highest bearing temperature is the permission operating temperature of used fiber-reinforced plastic, during charged grinding skive quiet, dynamic accuracy stable.
The utility model has designed 2 insulating parts, the two mating reaction, the steel screw can reliably be insulated when connection tightens up two steel components core bodys and emery wheel fixing body, form solidity assembly type integral insulation ring flange forever, have precision and dynamic and static state performance near integrated steel same specification ring flange.Simple in structure, easy to assembly, with low cost.
