Description
Technical field:
The present invention relates to a kind of process of definite processing work offset, particularly relate to a kind of process of definite electromagnetic core-free clamp workpiece eccentricity, belong to field of machining.
Background technology:
In the Grinding Process of disk-like accessory especially rolling bearing Internal and external cycle, generally use the electric magnetic no-core clamp clamping workpiece, these anchor clamps are applicable to batch machining.The operation principle of electric magnetic no-core clamp is: an end face of workpiece to be machined is leaning against under the effect of magnetic force on the end face of magnetic pole, the cylindrical of workpiece is leaning against under the effect of the offset between workpiece and the magnetic pole on back support and the lower support, during grinding work piece, rely on magnetic force that the end face of workpiece and the end face of magnetic pole are adjacent to, workpiece is rotated with magnetic pole, and rely on the offset between workpiece and the magnetic pole that the cylindrical of workpiece and the supporting surface of two supports are adjacent to, the size and Orientation of offset between workpiece and the magnetic pole, be to use two important indicators of these anchor clamps, crudy is had material impact.In actual process,, the workpiece to be machined outer surface is scratched if offset is excessive; If offset is too small, workpiece can fly out again and cause danger; No matter offset is excessive or too smallly all can cause harmful effect to crudy.When changing product type, all to spend several hrs at least to the size and Orientation of offset through adjusting repeatedly, tens hours at most, have a strong impact on production efficiency and product quality.
Traditional method of adjustment is fully with workman's oneself operating experience, and is not only time-consuming, and precision is difficult to guarantee.Therefore people have done different trials to the technology of determining the processing work offset, as disclosing the method for result of measurement of eccentricity in a kind of display optical system among the Chinese patent CN1702442A, wherein the offset of each lenticular element surfaces in the lens combination can be shown, and the offset that shows can be the offset that amplifies, proportion of utilization coefficient in addition can show the sectional view of lens combination; And for example disclose a kind of aspheric surface offset of non-spherical lens and the assay method and determinator of direction thereof measured among the Chinese patent CN1206512C, these methods all are to utilize special lenses and measuring technique to come the result of offset in the display optical system.Still do not determine the relevant report of electromagnetic core-free clamp workpiece eccentricity at present.
Summary of the invention:
The objective of the invention is: overcome the defective of existing electric magnetic no-core clamp adjusting process, a kind of process of size and Orientation of efficient, high-precision definite electromagnetic core-free clamp workpiece eccentricity is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of process of definite electromagnetic core-free clamp workpiece eccentricity, its concrete steps are:
A. according on electric magnetic no-core clamp, wanting the size of processing work specifications and models to determine an offset;
B. make a standard eccentric part according to the size of this offset;
C. at upper edge, the outer face offset direction of the standard eccentric part cylinder one end line that makes marks;
D. the cone one end insertion with the standard eccentric part has in the magnetic pole of inner cone, two conical surfaces is matched, and the mark line of offset is dropped between the back support and lower support of electric magnetic no-core clamp, connects magnetic switch the standard eccentric part is fixed;
E. will the back support and lower support near the face of cylinder of standard eccentric part, and will the back support and lower support is fixed with screw, the disconnection magnetic switch takes off the standard eccentric part;
F. will further process according to the processing method of routine through the processing work of above step and get final product.
The cylindrical of described standard eccentric part is made of a cylinder and a cone, and endoporus is that hollow runs through the face of cylinder, and the distance between cylinder center line and the cone center line is the size of offset.
The outside diameter on the described standard eccentric part face of cylinder equates with the nominal diameter of workpiece to be machined cylindrical.
The inner face of the face of cylinder one end of the end face of described magnetic pole and standard eccentric part leaves the gap, and the conical surface of standard eccentric part and the inner conical surface of magnetic pole are close under the effect of magnetic force, and then cooperatively interact.
The operation principle of electric magnetic no-core clamp is in the present invention: magnetic pole is connected with the electric magnetic no-core clamp end cap with screw, an end face of processing work is close to the end face of magnetic pole under the effect of magnetic force, the periphery of workpiece supports with the back under the effect of offset and lower support is close to, the back is supported and lower support is screwed on supporting seat, the back is supported and the position of lower support can be adjusted by the hole of in-line, for the end face that makes magnetic pole and processing work is located reliable, on the end face of magnetic pole, along the circumferential direction offer three breach, during work processing work with magnetic pole together with the electric magnetic no-core clamp end cap along with electric magnetic no-core clamp rotates, under the effect of emery wheel, can process the inner surface of processing work.
Positive beneficial effect of the present invention:
1. the present invention has improved the operating efficiency of adjusting anchor clamps.Use this process of determining electromagnetic core-free clamp workpiece eccentricity, do not need to adjust repeatedly the size and Orientation that just can determine the workpiece offset rapidly, can save more than 80% of adjustment time, improved the operating efficiency of adjusting anchor clamps.
2. the present invention has improved the adjustment precision of anchor clamps.Because process of the present invention adopted the standard eccentric part to adjust, making has a best offset man-hour in that processing work is added; Again because therefore the underlined line of standard eccentric part maximum eccentricity amount direction has guaranteed that the direction of maximum eccentricity amount drops between two supports, so use this process of determining electromagnetic core-free clamp workpiece eccentricity can obviously improve the machining accuracy of workpiece.
3. the process of definite electromagnetic core-free clamp workpiece eccentricity of the present invention, owing to do not change the agent structure of original electric magnetic no-core clamp, adjusting process method simple possible, cost is lower, and is easy to utilize.
