Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
The utility model magnetic floats grinding table, as shown in Figure 1, comprises base 1, push rod 4 and is located at the platform base 7 of push rod 4 upper end, wherein base 1 use that workbench can be made stable, during use, be placed in by drawing die on platform base 7, grinder carries out grinding operation.Be provided with the floating riser device that magnetic is floating in this grinding table, structure is simple and convenient, stressed to balance in process of lapping, ensures uniform and stable grinding, to improve the crudy of wire-drawing die.
Rely on magnetic buoyance lift to fall in the utility model, be provided with the first magnetic patch 9 in the lower end of push rod 4, below the first magnetic patch 9, be provided with second magnetic patch 10 contrary with its magnetic.When being placed on platform base 7 by wire-drawing die, a downward power being produced to push rod 4, there is between the first magnetic patch 9 and the second magnetic patch 10 thrust of mutual exclusion, keep the balance of two power.The effect of power between first magnetic patch 9 and the second magnetic patch 10, can carry out corresponding adjustment at random with the change of stressing conditions in the process of grinding, with force balance, ensures the stability to the grinding of wire-drawing die circumference.
For increasing support force, with the drawing die making this grinding table be applicable to different size, set up three magnetic patch 11 contrary with its magnetic in the below of the second magnetic patch 10, to provide support thrust.Due to magnetic patch conventional on market substantially time standard, the magnet cost as special requirement customized is higher, and can increase the volume of workbench, so adopt the mode that secondary pressurized supports in the utility model, to reduce costs.And the support force size of this secondary pressurized is adjustable, to obtain the support force of different size, applicability is better.
In the utility model, preferably, the mode of screw thread spinning in and out is adopted to control to adjust support force size.Second magnetic patch 10 and the 3rd magnetic patch 11 are located in regulating sleeve 2, and the second magnetic patch 10 is fixed on regulating sleeve 2 upper end, and the base for supporting of the 3rd magnetic patch 11 lower end can move up and down by relative adjustment cover 2, is controlled the size of support force by spacing.Regulating sleeve 2 outer wall is provided with one section of screw thread, is connected with adjustment driver plate 12 threaded engagement be located in base 1, controls the support distances between the 3rd magnetic patch 11 and the second magnetic patch 10 by adjustment driver plate 12.Regulating the lower end of driver plate 12 to be provided with location jump ring 13, to limit the axial displacement regulating driver plate.
As shown in Figure 1, by regulate regulate driver plate 12, make regulating sleeve 2 precession or back-out, base for supporting relative adjustment cover 2 wall move, base for supporting drive the 3rd magnetic patch 11 relatively on move or move down.Along with the thrust that diminishes of the distance between two magnetic patch becomes large gradually.The relative repulsion pushed away mutually of pitch smaller between second magnetic patch 10 with the 3rd magnetic patch 11 becomes greatly, and support force becomes large relatively; Contrary spacing becomes large, and repulsive interaction diminishes, and support force becomes large relatively.
In the utility model, be provided with belt pulley 8 outside push rod 4, belt pulley 8 rotates and drives push rod 4 and platform base 7 to rotate, well to carry out polishing grinding.Platform base 7 covers on push rod 4 upper end, between be provided with bearing 6, ensure obtain good rotating property.Be provided with cover for seat 3 in the outside of regulating sleeve 2, cover for seat 3, in up-small and down-big trapezoidal shape structure, not only makes this workbench more attractive in appearance and strengthens its Stability Analysis of Structures.
Preferably, regulating sleeve 2 is provided with vertical stopper slot I, is provided with restriction regulating sleeve 2 in stopper slot I and moves up and down the stop screw 5 of stroke.Stop screw 5 is connected in stopper slot I through the projecting edge of base 1 and cover for seat 3, to limit regulating sleeve 2 upwards and downward movement travel, the adjustable range of restriction support force in suitable scope, and is avoided in use procedure because accommodative excess causes part injury phenomenon.
In like manner, belt pulley 8 outer wall is also provided with stopper slot II, stop screw 5 is plugged in stopper slot II through platform base 7.What stop screw 5 herein limited push rod 4 moves up and down stroke, ensures that it moves up and down in suitable scope.
In the utility model, also can arrange multiple three, four magnetic patch in same regulating sleeve 2, multistage support obtains the support force being satisfied with suitable size, provides larger support thrust to meet processing conditions.
It is simply light and handy that the utility model magnetic floats grinding table structure, without the need to the lifting structure that peripheral hardware is numerous and diverse, by the mutual thrust between the first magnetic patch 9, second magnetic patch 10 of repelling each other and the 3rd magnetic patch 11, promote push rod 4 thus drive the wire-drawing die floating riser be placed on platform base, can balancedly grind stressed, coordinate belt pulley 8 to drive platform base 7 to rotate, thus realize the grinding and polishing to wire-drawing die very stable and uniform.This workbench has the pressurization of secondary, provides larger support force, makes it be applicable to the wire-drawing die of the larger heavier-weight of processing grinding, and applicability is wider, and more convenient, reduction job costs of can increasing work efficiency, have stronger practicality.
By reference to the accompanying drawings the utility model is exemplarily described above; but the utility model is not limited to aforesaid way; as long as adopt method of the present utility model is conceived and technical scheme is carried out the improvement of various unsubstantialities or directly apply to other occasion, all drop in protection domain of the present utility model.
