Abstract
The utility model discloses a processing clamp, which comprises a magnetic upper pressing plate (3), a magnetic lower pressing plate (1) and fastening screws (4). Threaded holes (5) are evenly distributed on the magnetic upper pressing plate (3); counter bores (6) are evenly distributed on the magnetic lower pressing plate (1); the fastening screws (4) penetrating through the counter bores (6) are connected with the threaded holes (5); a processed product (2) is positioned between the magnetic upper pressing plate (3) and the magnetic lower pressing plate (1) and at a magnetic pole (3) end of an electromagnetic centerless clamp machine tool; and the lower portion of the product (2) is positioned on a support (8). The split bearing external diameter grinding processing clamp can solve the problems of small size (cutting seam loss) of the outside diameter and low precision of an outer ring of an existing split bearing, effectively improves the processing precision of product parts, accordingly enhances product precision, prolongs the service lift of a bearing and enables the product to be applicable to precise working environments.
Description
Technical field
The utility model belongs to a kind of frock clamp, relates generally to a kind of split bearing external diameter grinding anchor clamps.
Background technology
Split bearing is to use in the bearing of more special work condition environment work.So-called split bearing is combination bearing again, is the complete integral bearing part of a cover to be dissectd be separated into two halves, is convenient to the bearing of installing and using in special working environment (installing space in the working environment is limited).
The outer ring production and processing of known split bearing is exactly the bearing outer ring grinding to be dissectd to fabricated part get final product.The greatest problem that this production and processing mode exists is: because the certain cover loop material of loss is wanted in the formation of joint-cutting, there is boss at the joint-cutting place of outer ring and makes the size decreases of outer ring external diameter, outer ring, assembling back is that dissecing of a big ellipse and lasso processed the distortion that the structural stress that causes the lasso internal balance changes and produces, have a strong impact on the precision of product, not only radially wobble big, vibrate also greatly, and life of product is short, can not be used in accurate working environment.Existing bearing ring special processing equipment, the production efficiency height, the machining accuracy height, but only be used in whole revolving parts processing.The processing of existing split bearing why adopt one-piece parts be worked into finished size just dissect can, reason is that the bearing parts (semicircle) after dissecing can't be processed on existing bearing ring process equipment.If carry out grinding after the first roughing again, must adopt suitable anchor clamps to fix workpiece.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, fixed split bearing external diameter grinding anchor clamps, the existing split bearing outer ring of solution outside dimension little (cuing open the seam loss), the drawback that precision is low, effectively improve the machining accuracy of product parts, thereby improve the precision of product, prolong bearing service life, make product be applicable to accurate working environment.
The purpose of this utility model can adopt following technical scheme to realize: it comprises magnetic top board, lower platen and trip bolt, on top board, be evenly equipped with screwed hole, on the magnetic lower platen, be evenly equipped with counterbore, counterbore and screwed hole correspondence, trip bolt passes counterbore and is threaded with screwed hole, needs product processed to be positioned between magnetic top board and the magnetic lower platen.
The utility model is applicable on electric magnetic no-core clamp equipment product is processed, and adopts the upper and lower template of magnetic material, and double-split bearing ring external diameter to split bearing on the electric magnetic no-core clamp lathe in location is processed.The utility model can guarantee that in product processing the production and processing smoothly of subdivision part can guarantee the whole detection precision (but also split detects) of subdivision part again.The product quality that processes is the same with the imported product performance according to detecting reflection.The utility model has been realized allowing the semicircle bearing ring after dissecing be converted to the bearing ring of full circle and has been implemented in and carried out high-precision whole processing on the existing equipment.Can guarantee that the production and processing smoothly of split bearing part can guarantee integral body processing, the accuracy of detection (but also split detects) of subdivision part again, external diameter is that the use benchmark of bearing also is the processing technology benchmark of bearing.The machining accuracy of external diameter just directly has influence on the precision height of the subsequent handling processing of bearing parts.Improve the machining accuracy of external diameter, just be equivalent to improve the machining accuracy of whole bearing parts.Improve the production and processing precision of split bearing part, make precision raising, be applicable to that this bearing uses in the working environment of precision by the split bearing product of split bearing part assembling.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model location schematic diagrames to split bearing on the electric magnetic no-core clamp lathe.
Shown in the figure: 1, lower platen, 2, product, 3, top board, 4, clamp nut, 5, magnetic pole, 6, supporting.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: the utility model comprises magnetic top board 3, magnetic lower platen 1 and trip bolt 4, on magnetic top board 3, be evenly equipped with screwed hole, on magnetic lower platen 1, be evenly equipped with counterbore, counterbore and screwed hole correspondence, trip bolt passes counterbore and is threaded with screwed hole.
As shown in Figure 2: need product processed 2 to be positioned between magnetic top board 3 and the magnetic lower platen 1.Product 2 is positioned at magnetic pole 5 one ends on the electric magnetic no-core clamp lathe, and product 2 bottoms are positioned in the supporting 6.
During use, the semicircle bearing ring after dissecing is combined in the upper and lower pressing plate of packing into by the sequence number pairing, load onto fastening bolt then.Then adjust the assembly quality of mould and product and fastening, load onto that lathe is the same with normal product to carry out grinding.Be ground to need size after, take off from lathe, by the fastening bolt of dismantling mould is removed and gets final product.
Claims (1)
