Abstract
The utility model discloses an improved electromagnetic chunk, which can be used as a special clamping tool of internal grinding machine and external grinding machine. The parts do not deform when grinding internal circularity, external circularity and end face of circular work piece or special circular work piece with thin wall after these work pieces are absorbed and clamped, therefore, high process precision can be achieved. Consisting of a chunk body, a coil and a cover plate, the utility model is characterized in sector-shaped area separated by the chunk body and cover plate, coils arranged in each sector-shaped area and the small electromagnetic chunk formed by the chunk body and the cover plate in the sector-shape area.
Description
(1) technical field
The utility model relates to fixture for grinding machine, is specially the circular electromagnetic chunk of improvement
(2) background technology
The typical circular magnechuck mainly contains circular concentric and two kinds of surperficial magnetic pole forms of vertical bar shaped, and concrete structure is seen Fig. 1, sees Fig. 2 that the circular concentric sucker does not have suction substantially to annular workpiece 1; The vertical bar shaped sucker can sticking annular workpieces 2, but only limit to process end face because can't cutter relieving during inside and outside round grinding, so the occasion of inapplicable inside and outside round grinding.Therefore these two kinds of suckers are not suitable for circular workpiece are carried out grinding, particularly for being suitable for thin wall circular shape workpiece are not carried out inside and outside round grinding, and use the method for clamping clamping instead, can make workpiece produce distortion again, influence machining accuracy.
(3) summary of the invention
At existing typical circular magnechuck weak point, the utility model provides a kind of circular electromagnetic chunk of improvement, it can be used as the special fixture of inside and outside circle mill, the machining accuracy height of circular workpiece of grinding or extraordinary thin wall circular shape workpiece behind the sticking, and part can not be out of shape because of clamping.
Its technical scheme is such: it comprises disk body, coil, panel, it is characterized in that: described disk body, panel five equilibrium are separated out sector region, and coil and this regional disk body, panel that each sector region distributes form little magnechuck.
It is further characterized in that: described panel is provided with T-slot.
The utility model adopts after the said structure, because a circumference is divided into several sector regions, during sucker energising work, excite magnetic force jointly by coil and disk body, by fan-shaped magnetic pole on the disk body and disk body frame magnetic force is passed to panel, on panel, form and press the phase different pole that sector region distributes, all magnetic poles all work during circular workpiece touch panel, because each sector region is a module independently, can produce stronger holding force sticking workpiece on the surface, guarantee processing and machining accuracy round piece; And being provided with of T-slot can be adjusted different processing radiuses in order to the auxiliary clamp of magnetic conduction to be installed on the panel, further guaranteed the round piece especially processing of thin-walled round piece, and further guaranteed machining accuracy.
(4) description of drawings
Fig. 1 is the schematic diagram of general circular electromagnetic chunk;
Fig. 2 is the schematic diagram of vertical bar shaped magnechuck;
The structural representation that Fig. 3 looks for the utility model master;
Fig. 4 be Fig. 3 A-A to revolved sectional view and with the installation graph of a relation of workpiece.
(5) specific embodiment
See Fig. 3, Fig. 4, the utility model comprises disk body 5, coil 4, panel 6, disk body 5, panel 6 five equilibriums are separated out sector region, the size of sector region, quantity are decided on requirement, be divided into out 6 zones among Fig. 3, coil and this regional disk body, panel that each sector region distributes form little magnechuck, should locate the regional small sucker that forms as coil among Fig. 44 and the sector region 3 and the disk body 5 of panel 6, and panel 6 is provided with T-slot 2.
Below in conjunction with accompanying drawing the course of work of the present utility model is described: when circular workpiece 1 is put into panel 6, energising work, excite magnetic force to pass to panel 6 jointly by coil 4 and disk body 5, on panel 6, form and press the phase different pole that sector region distributes, during then circular workpiece 1 touch panel 6 all magnetic poles are all worked, because each sector region is a module independently, can produce stronger holding force on the surface, the auxiliary clamp such as the magnetic cushion block 7 of magnetic conduction are installed on T-slot 2, workpiece pad is risen, so that cutter relieving is adjusted the processing radius.
Claims (2)
1. Gai Liang circular electromagnetic chunk, it comprises disk body, coil, panel, it is characterized in that: described disk body, panel five equilibrium are separated out sector region, and coil and this regional disk body, panel that each sector region distributes form little magnechuck.
2. according to the circular electromagnetic chunk of the described improvement of claim 1, it is characterized in that: described panel is provided with T-slot.
