The height in described gap 18 is 0.5-2.5mm.
The diameter of described cooling fluid hand-hole 14 is 1.5-4.5mm.
Because the present invention has adopted interior technical scheme for cooling fluid reduction wheel grinding district temperature, can effectively reduce the temperature of grinding wheel grinding area, reach the workpiece of avoiding burning, improved the grinding efficiency and the purpose in prolongation grinding wheel life-span; Use this device when workpiece such as grinding high accuracy blade of aviation engine, grinding speed is brought up to 1350 mm/min from 650 mm/min, and the grinding ratio of grinding wheel is increased to 1100 from 450; Technical scheme of the present invention not only is suitable for cooling of grinding wheel unit, also is fit to the similar mechanical device of needs cooling.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a sealing principle schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described further.
With reference to Fig. 1, supply the grinding wheel unit of cooling fluid in a kind of, comprise the connected mill bar 2 of a motor 13 and an end, be provided with ring flange 1 near on the mill bar 2 of motor 13 sides, outer surface at the mill bar 2 of the opposite side of ring flange 1 is provided with water jacket 6, the other end at mill bar 2 is provided with the tight screw 11 of assembly, the other end of piecing together tight screw 11 is connected with grinding wheel 10 by the secondary flange 9 of emery wheel master flange 8 and emery wheel successively, on ring flange 1, be provided with cooling fluid inlet 5, be provided with cooling fluid leak 4 with the enter the mouth position of 5 symmetries of cooling fluid, water jacket 6 is provided with between the bar 2 with mill and cooling fluid inlet 5 gaps that communicate 18, the height in described gap 18 is 0.5-2.5mm, at described emery wheel master flange 8, the axial equal height of secondary flange 9 of emery wheel and grinding wheel 10 is provided with identical communicate with each other and the cooling fluid hand-hole 14 that communicate with gap 18 of diameter, the diameter of described cooling fluid hand-hole 14 is 1.5-4.5mm, between ring flange 1 and water jacket 6 junctions and mill bar 2, be provided with first sealing ring 3, between water jacket 6 and emery wheel master flange 8 junctions and mill bar 2, be provided with second sealing ring 7.Motor 13 is configured in the motor case 12.
With reference to Fig. 2, described first sealing ring 3 and second sealing ring 7 include a cylindrical 16, and a side of cylindrical 16 is an end face 17, and opposite side is inclined-plane 15.
Operation principle of the present invention is such:
See figures.1.and.2, when the gap 18 that cooling fluid is injected between mill bar 2 and the water jacket 6 by cooling fluid inlet 5 by certain pressure, be in the seal chamber that forms between ring flange 1 and emery wheel master ring flange 8 and the mill bar 2 time, it will be to the diffusion of whole cavity periphery, because the axial equal height position at emery wheel master flange 8, the secondary flange 9 of emery wheel and grinding wheel 10 is respectively equipped with the identical cooling fluid hand-hole 14 of diameter, it can reach the effect of cooling grinding wheel grinding area temperature by cooling fluid hand-hole 14 centrifugal grinding faces to grinding wheel 10.Yet, owing between the secondary flange 9 of mill bar 2 and ring flange 1, emery wheel master flange 8 and emery wheel certain clearance is arranged all, so cooling fluid also can leak into a side of motor case 12 and grinding wheel 10 by these gaps, the high speed of grinding wheel 10 is rotated in and has formed very high pressure around it in addition, so cooling fluid also runs into big resistance during by cooling fluid hand-hole 14.But because the present invention 2 is provided with the first identical sealing ring 3 of a pair of structure and second sealing ring 7 on the mill bar, can stop cooling fluid to ooze out seal chamber, guarantee that the cooling fluid in the seal chamber is in the state of elevated pressures.
With reference to Fig. 2, the operation principle of sealing ring is such: the cooling fluid between mill bar 2 and the coolant jacket 6, when mill bar 2 rotates at a high speed, at 15 places, inclined-plane of sealing ring since action of centrifugal force flow to cylindrical 16 places of sealing ring.In the cooling fluid at end face 17 places of sealing ring because action of centrifugal force, also flow to cylindrical 16 places of sealing ring, cylindrical 16 place's coolant pressures at sealing ring reach balance, cooling fluid stops along the axial flow of mill bar 2, thereby play sealing function, ensure that the cooling fluid in the seal chamber is injected into emery wheel cooling fluid hand-hole 14 with high pressure conditions, and under centrifugal action, arrive the grinding face of grinding wheel 10, reach cooling grinding wheel 10 temperature, the purpose of the workpiece that prevents to burn.
Among the figure: 1 is ring flange, and 2 are the mill bar, and 3 is first sealing ring, 4 is leak, and 5 are the cooling fluid inlet, and 6 is water jacket, 7 is second sealing ring, and 8 is emery wheel master flange, and 9 is the secondary flange of emery wheel, 10 is grinding wheel, and 11 for piecing together tight screw, and 12 is the motor case, 13 is motor, and 14 is emery wheel cooling fluid hand-hole, and 15 is the inclined-plane of sealing ring, 16 is the cylindrical of sealing ring, and 17 is the end face of sealing ring, and 18 is the gap between water jacket 6 and the mill bar 2.
