Abstract
The utility model belongs to a component of a grinding machine tool, particularly a superfine head used for a superfine grinding machine to process a ferrule of a miniature bearing. The superfine head used for a superfine grinding machine to process a ferrule of a miniature bearing has a main technical proposal that a sliding block which can move on a bracket up and down is sheathed on the bracket which is tightened on a base. The left end of the sliding block is separately hinged with the middle part of an L-shaped lever and the lower end of a connecting rod by pin shafts, and parallel blocks are respectively hinged on the upper ends of the L-shaped lever and the connecting rod by pin shafts to form a parallel four-connecting rod mechanism. The right end of the L-shaped lever and a guide shaft are hinged. The guide shaft is positioned in the base, and can move in the base up and down. Hone clamps are arranged on the positions of the bracket, which are corresponding to the parallel blocks.
Description
The utility model belongs to a kind of parts of grinding machine, especially a kind of super smart head that is used for super lapping machine processing miniature bearing lasso.
In the prior art, the extra accuracy oilstone is installed on the piston rod end in the oscillating mechanism usually, thereby machining accuracy is lower, installs with operation cumbersome.
The purpose of this utility model is a kind of super smart head of processing the miniature bearing lasso of design.
Its main technical schemes be anchored on the support of base one in cover can be on support upper and lower mobile slide block, the left end of slide block utilize bearing pin respectively and be anchored on the bearing at bearing pin two ends and the lower end of the middle part of L shaped lever and connecting rod hinged, and utilize bearing pin respectively in the upper end of lever and connecting rod and be anchored on the bearing hinge connection parallel block at bearing pin two ends, form a parallel four-bar linkage, the right-hand member of lever and an axis of guide are hinged, the axis of guide is positioned at base, and can be upper and lower mobile in base, the position corresponding to parallel block on support is provided with the oilstone folder.
Its another feature is that the depression bar that can push down oilstone is arranged on parallel block.Right-hand member at lever connects a little axle, and the other end of little axle utilizes a bearing to be connected with the axis of guide.
This device is mainly used in the inside and outside rolling bearing lasso of 26 millimeters of processing external diameter≤Φ, is a kind of brand-new structure.It mainly has following characteristics: the one, simple in structure, volume is little, in light weight, rotary inertia is little, frequency of oscillation still keeps rigidity preferably when reaching more than 1000 times/minute, be particularly suitable for for processing miniature bearing inside and outside lasso; The 2nd, entire mechanism compact conformation, reaction flexible, easy to adjust quick, fault rate is low; The 3rd, this mechanism range of work is wide, almost all can process the lasso of whole miniature bearing series, and when changing the processing specification, only need change few part and get final product.This structure Design is made, and has filled up domestic blank in this regard.
Originally super smart head unit as shown in the figure: mainly be made up of base 1, support 2, lever 3, connecting rod 4, slide block 5, the axis of guide 6, parallel block 7, little axle 8, oilstone folder 9 etc.Base 1 is fixedlyed connected with the axis of oscillation in the oscillating mechanism, and support 2 is fixed on the base 1, is the basis of whole super smart head, and oilstone folder 9 is fixed on the support 2, and its center overlaps with the center of base 1, and can finely tune by adjustment screw.The bearing that lever 3, connecting rod 4 and parallel block 7 utilize 4 bearing pins respectively with slide block 5 and be anchored on the bearing pin two ends is hinged, form a parallel four-bar linkage, the automatic compensation and the oilstone that are used for oilstone compress, the big I of its compensation rate is regulated by the length that the axis of guide 6 stretches out, and can slide on support 2 by slide block 5 and finely tune.The axis of guide 6 is connected with little axle 8, and links to each other with lever right-hand member in the quadric chain by bearing, and the axis of guide 6 can slide in base 1, and links to each other with piston rod in the oscillating mechanism, with the automatic motion of realization quadric chain.Be fastenedly connected oilstone folder 9 in the upper end of support 2, oilstone is positioned at oilstone folder 9, fixedly connected one depression bar 10 that is used to push down oilstone on parallel block 7.
The course of work of this super smart head unit is: whole super smart head mechanism drives the axis of guide 6 and moves downward under effect under the drive of oscillating mechanism, and 3 on lever is rotated counterclockwise motion around bearing pin under the axis of guide 6 drives.Under the effect of parallel four-bar linkage, lever 3 drives parallel block 7 and moves in the horizontal direction, and oilstone is pressurizeed, and realizes oilstone pressurization and automatic compensation function.The big I of oilstone pressure is regulated by cylinder air pressure size, and when time processing finished, the axis of guide 6 moved upward under cylinder action, drives lever 3 and does the clockwise direction rotation, and parallel block 7 moves in the horizontal direction, unclamps oilstone, finishes the function of entire mechanism.
Another patent of the visible the applicant's application of the detailed technology of relevant oscillating mechanism " oscillating mechanism of processing miniature bearing lasso ".
