Abstract
The utility model relates to a circular support valve gate grinding machine belonging to a special tool for repairing valve gates. The utility model is characterized in that a grinding disk comprises a driving disk 1 and a support ring 4 which both are in the same shaft, the driving disk 1 is connected with the support ring 4 by a connecting piece 2 and a grinding head 6 is installed in the groove of the support ring 4. The utility model by proper connections blocks that the deformation of the driving disk 1 caused by axial direction grinding pressure is transferred to the support ring 4, for the driving disk 1 and the support ring 4 are synchronously rotating in the same shaft, the influence of the grinding head 6 produced by the deformation is minimum, and thereby, the grinding faces are smooth and clean, the seal effect of the valve gate is favorable and the service life is long.
Description
A kind of ring-shaped bearing valve grinding machine, the utility model belongs to the specific purpose tool of repairing valve.
The goodness of fit should be not less than 50～65% (low pressure valve is 20～30%) when the Grinding Quality of valve sealing face generally required it closely to contact, and surface smoothness must not be lower than 9 (low pressure valve must not be lower than 7).Reach the structural behaviour and the accuracy of manufacture that these requirements depend primarily on abrasive disk.The version of abrasive disk at present commonly used can be divided into two big classes: the one, and the eccentric rotor that utilizes dead axle to rotate drives the abrasive disk with grinding tool, achieves multiple platform motion.To be abrasive disk make it produce centrifugal force in rotation because of the effect of eccentric rotor to the shortcoming of this type, this power causes the grinding bumpy motion, influence is by the quality of lapped face, and limited the raising of research speed, also causes harmful effect for the parts life-span of abrasive disk.Another kind of is that the abrasive disk dead axle rotates, and the bistrique that can rotate around self axis has been installed on the dish.The synchronous coaxial rotation of bistrique and abrasive disk (being the revolution of bistrique).Other adds a bracket panel with the coaxial and different speed of abrasive disk, utilizes both differential and orders about bistrique and rotate (being the rotation of bistrique) around the axis of self, thereby make bistrique obtain the compound motion that an existing revolution has rotation again.The advantage of this mill is not have centrifugal force, running steadily, can improve grinding speed, productivity ratio is improved, but its fatal shortcoming be mill under the situation that is subjected to axial grinding pressure, mill outer periphery is tilted upward, the distortion of whole mill camber shape takes place, and this distortion is directly reached the bistrique that is mounted thereon, make its axle center crooked, make the uneven phenomenon that is occurred indent or evagination by the mill performance.Can not satisfy the above-mentioned contact goodness of fit and be not less than 50～65% requirement, influence the compactness and the service life of valve sealing face.
The purpose of this utility model is that design a kind ofly is divided into driving-disc and support ring two parts with abrasive disk, by suitable connection, blocks abrasive disk and passes to bistrique because of the distortion that caused by axial grinding pressure, and bistrique is subjected to the grinder of deformation effect minimum.
The abrasive disk that is characterised in that of the present utility model is divided into driving-disc 1 and support ring 4 two parts, and driving-disc 1 and support ring 4 are coaxial, and driving-disc 1 is connected with support ring 4 by connector 2, and bistrique 6 is installed in the radial slot of support ring 4.
Below in conjunction with accompanying drawing the utility model is specified:
Fig. 1: the structural representation of ring-shaped bearing valve-seating dish,
The vertical view of Fig. 2: Fig. 1.
Driving-disc 1 is connected with support ring 4 by connector 2, and driving-disc 1 rotates with support ring 4 coaxial, synchronous dead axles, can be installed in the radial slot of support ring 4 around the grinding head 6 usefulness screws 3 that self axis rotates.Connector 2 can be tooth, key, pin, steel ball etc., and large diameter support ring can connect with width of cloth bar formula structure.Radial slot on the support ring 4 is to be used for being installed as the sealing surface that adapts to different diameter of valve or different in width and the grinding head of selecting different-diameter for use, to reduce the quantity of support ring 4.Bistrique 6 is revolution with the rotation of support ring 4.On the cylindrical of bistrique 6, be with a rubber ring 5, when being installed, bistrique 6 allow rubber ring 5 be close to the cylindrical of bracket panel 8, bracket panel 8 and driving-disc 1 have certain speed discrepancy (can allow the rotating speed of bracket panel 8 be zero for simplifying the mill structure), in operation process, utilize the speed discrepancy of bracket panel 8 and support ring 4, order about bistrique 6 around self axis rotation by the bracket panel 8 and the friction (also can make the gear meshing transmission therebetween) of rubber ring 5, this motion is the rotation of bistrique 6.Arrive this, bistrique 6 is finished the compound motion that existing revolution has rotation again in process of lapping, and each abrasive particle can form staggered complex track on by ground flat 9 and be netted, and the wearing and tearing of grinding tool 7 are even like this, grinds that to cut efficient also higher.
The abrasive disk that the utility model is done the circumference rotation with dead axle has been divided into driving-disc 1 and support ring 4 two parts, by suitable connection, blocked driving-disc 1 and passed to support ring 4 because of the distortion that caused by axial grinding pressure, can drive support ring 4 and driving-disc 1 coaxial, synchronous rotation again, thereby obtain an abrasive disk that does not have centrifugal action, bistrique 6 to be subjected to the deformation effect minimum.Thereby guarantee smooth bright and cleanly, make valve reach best sealing effectiveness and longer service life, created necessary condition for the rotating speed and the efficient of raising grinder again by abradant surface.
