Description
Technical field
The utility model relates to steel rail grinding device technical field, in particular to a kind of steel rail grinding emery wheel fixture with high safe flexibility.
Background technology
In traditional sander, normally adopt bolt fixed mode to be fixed on by emery wheel on the chuck of sander main shaft, time and effort consuming, be difficult to realize changing fast.So develop a kind of fixture to adopt the depression bar that can pump by grinding wheel spindle clinching on emery wheel mount pad, realize the multiple emery wheels on emery wheel mount pad being carried out to fastening and loosening simultaneously, improve replacing efficiency, but depression bar is unclamped by Driven by Hydraulic Cylinder or keeps clamping, in bruting process, losing efficacy, unloading phenomenon easily appears in hydraulic system, causes depression bar to drop on rail, there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of steel rail grinding emery wheel fixture with high safe flexibility, with solve existing emery wheel fixed form exist lost efficacy, the risk of unloading and bring the problem of potential safety hazard.
For realizing the utility model object, the technical scheme adopted is: a kind of steel rail grinding emery wheel fixture with high safe flexibility, comprise emery wheel, emery wheel mount pad and depression bar, one end of depression bar is by emery wheel fastening on emery wheel mount pad, and the other end of depression bar stretches out emery wheel mount pad and is connected with pressing plate; The holddown spring be set on depression bar is provided with between pressing plate and emery wheel mount pad; Pressing plate is equipped with the drive unit driving it to the motion of emery wheel mount pad direction.
Further, described drive unit is hydraulic cylinder, and the piston rod of hydraulic cylinder is to being located on pressing plate.
Further, an emery wheel mount pad correspondence arranges a described pressing plate, and on emery wheel mount pad, all depression bars of fixed emery wheel are all connected with described pressing plate.
Further, an emery wheel correspondence arranges two depression bars, and two depression bars lay respectively at the grinding wheel spindle two ends of emery wheel.
Further, one end of the fixed emery wheel of described depression bar is L shape structure, and the grinding wheel spindle of emery wheel is buckled on emery wheel mount pad through L shape structure.
The beneficial effects of the utility model:
1, depression bar is made by grinding wheel spindle fastening on emery wheel mount pad by the elastic force of the holddown spring between pressing plate and emery wheel mount pad, and then make emery wheel be in the state of fixing to clamp, now hydraulic cylinder or other drive units are not in duty of exerting pressure, such dependence frame for movement fixes to clamp emery wheel, in bruting process, avoid the potential safety hazard produced because of hydraulic system fails, when dismounting and change emery wheel, by drive unit, pressing plate is moved to emery wheel mount pad direction, holddown spring is compressed, depression bar unclamps emery wheel, carries out dismounting and change;
2, drive unit only uses when dismantling emery wheel, and pressing plate and drive unit can adopt disconnected form, and installing/dismounting more flexibly, also reduces cost;
3, compared with existing compression mode, structure is more effectively simple, and whole system first can dress up an entirety except pressing plate, reinstalls polishing dolly, is connected with corresponding pressing plate, is convenient to one and changes, also without the need to carrying out being connected and fixed between hydraulic cylinder and depression bar;
4, an emery wheel of this fixed structure compresses by two holddown springs, even if a depression bar fracture like this, also has another to compress, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is the front view of the grinding wheel fixture that the utility model provides;
Fig. 2 is the structural representation in fixture shown in Fig. 1 except drive unit.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the steel rail grinding emery wheel fixture with high safe flexibility that the utility model provides, comprise emery wheel 4, emery wheel mount pad 5 and depression bar 1, one end of depression bar 1 is by emery wheel 4 fastening on emery wheel mount pad 5, and the other end of depression bar 1 stretches out emery wheel mount pad 5 and is connected with pressing plate 3; The holddown spring 2 be set on depression bar 1 is provided with between pressing plate 3 and emery wheel mount pad 5; Pressing plate 3 is equipped with the drive unit 6 driving it to the motion of emery wheel mount pad 5 direction.
Drive unit 6 is hydraulic cylinder, and the piston rod of hydraulic cylinder is to being located on pressing plate 3, and indirect connection, also can adopt other drive units such as cylinder.Emery wheel 4 correspondence arranges the grinding wheel spindle two ends that two depression bar 1, two depression bars 1 lay respectively at emery wheel 4, and one end of the fixed emery wheel 4 of depression bar 1 is L shape structure, and the grinding wheel spindle of emery wheel 4 is buckled on emery wheel mount pad 5 through L shape structure.Specifically a pressing plate 3 can be set emery wheel mount pad 5 correspondence, and on emery wheel mount pad 5, all depression bars 1 of fixed emery wheel 4 are all connected with pressing plate 3, are convenient to integral installation.Also each emery wheel 4 correspondence can be made as required to arrange a pressing plate 3, independent dismounting and change can be carried out to different emery wheels 4 respectively.
Hydraulic cylinder uses when just dismantling emery wheel 4, does not participate in pressurization, avoid the potential safety hazard produced because of hydraulic system fails when emery wheel 4 works at ordinary times.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
