Abstract
The utility model discloses a grind oilstone hold -down mechanism, include support panel, drive actuating cylinder and depression bar, it is connected fixedly with support panel to drive actuating cylinder, it is connected with the connecting block to drive actuating cylinder's power take off end, the connecting block is articulated with the rear end of depression bar, the front end of depression bar is provided with antifriction bearing, the middle part of depression bar is articulated with the supporting shoe, supporting shoe fixed connection is on support panel, the front end of depression bar is grinding compressing tightly a little of oilstone, the position that compresses tightly a little remains unchanged and is arranged in by point correspondence department of abrasive surface all the time at grinding oilstone reciprocating motion in -process. The utility model discloses utilize lever principle, make the front end of depression bar compress tightly grinding the oilstone, in grinding oil masonry reciprocating motion carries out process of lapping, the compress tightly mid point position that a little keep by abrasive surface of depression bar to grinding the oilstone to remain throughout grinding the stable packing force of oilstone, like this, make grinding oilstone atress in the grinding even, effectively improved the quality of grinding.
Description
Technical field
The utility model relates to a kind of grinding oilstone hold-down mechanism.
Background technology
At present, slide valve buckle working face for railway brake valve class is all adopt oilstone to carry out machinery or underhand polish, the mode of its grinding is all exert pressure at oilstone two ends, grinding is realized by moving back and forth of oilstone, exert pressure due to oilstone two ends in existing lapping mode and cannot keep completely the same, cause oilstone two ends unbalance stress, cause final abradant surface smooth not, Grinding Quality is not high.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of structure simple, compact, and can improve the grinding oilstone hold-down mechanism of Grinding Quality.
The technical solution of the utility model is achieved in that a kind of grinding oilstone hold-down mechanism, it is characterized in that: comprise support panel, drive cylinder and depression bar, described driving cylinder and support panel are connected and fixed, the clutch end of described driving cylinder is connected with contiguous block, the rear end of described contiguous block and depression bar is hinged, the front end of described depression bar is provided with rolling bearing, middle part and the back-up block of described depression bar are hinged, described back-up block is fixedly connected on support panel, the front end of described depression bar is the compression point to grinding oilstone, the described position compressing point remains unchanged and is positioned at the mid point corresponding position in polished face all the time in grinding oilstone reciprocatory movement.
The utility model utilizes lever principle, the front end of depression bar is compressed grinding oilstone, moving back and forth at grinding oil masonry carries out in process of lapping, the compression point of depression bar to grinding oilstone remains on the point midway in polished face, and remain the stable thrust of grinding oilstone, like this, make grinding oilstone uniform force in grinding, effectively improve the quality of grinding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state figure of the present utility model.
Mark in figure: 1 is support panel, 2 for driving cylinder, and 3 is depression bar, and 4 is contiguous block, and 5 is rolling bearing, and 6 is back-up block, and 7 is grinding oilstone, and 8 is polished valve body.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, a kind of grinding oilstone hold-down mechanism, comprise support panel 1, drive cylinder 2 and depression bar 3, described driving cylinder 2 is connected and fixed with support panel 1, the clutch end of described driving cylinder 2 is connected with contiguous block 4, described contiguous block 4 is hinged with the rear end of depression bar 3, the front end of described depression bar 3 is provided with rolling bearing 5, middle part and the back-up block 6 of described depression bar 3 are hinged, described back-up block 6 is fixedly connected on support panel 1, the front end of described depression bar 3 is the compression point to grinding oilstone 7, the described position compressing point remains unchanged and is positioned at the mid point corresponding position in polished face all the time in grinding oilstone 7 reciprocatory movement.
Operation principle of the present utility model is: be positioned on support panel by polished valve body 8, then grinding oilstone is placed in the abradant surface place of polished valve body, make the compression of depression bar front end point be positioned at the mid point corresponding position in polished face simultaneously, then start and drive cylinder, the piston rod of driving cylinder is made to drive contiguous block to move upward, thus drive depression bar pin joint in the middle part of it to rotate, until the rolling bearing of depression bar front end is pressed on grinding oilstone, when grinding oilstone and being subject to the reciprocating forces of horizontal direction, rolling bearing rolls in grinding oilstone upper surface force, realize the substrate hold-down function of grinding oilstone.When the air draft of driving cylinder, drive the piston rod of cylinder to drive contiguous block to move downward, thus drive depression bar pin joint in the middle part of it to rotate, make the rolling bearing of depression bar front end leave grinding oilstone, grinding oilstone is taken off, complete the grinding to valve body.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
