Abstract
The utility model provides a novel grinding wheel for rail rectification and grinding. The novel grinding wheel for rail rectification and grinding comprises a grinding wheel body and a grinding wheel back disc. Taper bosses are uniformly arranged on the grinding wheel back disc, and are respectively mated with grooves of a grinding head flange. The taper bosses are provided with screwed holes for mounting fasteners. According to the utility model, the taper bosses are uniformly arranged on the grinding wheel back disc and are closely mated with the grooves on the grinding head main shaft flange, so that the deviation of coaxiality between the grinding wheel and the grinding head main shaft is reduced with the principle of tightness of taper surfaces. After the connection between the grinding wheel back disc and the grinding head flange is fastened, bolts would not bear the driving force from the grinding head or bear the counteractive impact force caused by unevenness of rails. When the novel grinding wheel is working, the driving force is transmitted by the taper bosses so as to prevent the bolts from being damaged by the driving force, such that the reliability for using the grinding wheel is improved, and the grinding wheel back disc is more firmly connected with the main shaft. In addition, the novel grinding wheel for rail rectification and grinding is of a simple structure.
Description
Technical field
The utility model relates to a kind of emery wheel, and the reconditioning emery wheel on particularly a kind of grinding rail surface belongs to the technical field of emery wheel.
Background technology
Rail reconditioning emery wheel is the special grinding wheel that the rail surface is carried out grinding.Rail reconditioning emery wheel comprises emery wheel body, emery wheel back of the body dish, and described emery wheel body and described emery wheel back of the body dish link into an integrated entity.The emery wheel back of the body has been folded accurate installation and has been fastened on effect on the grinding machine spindle, also to the effect of improving of emery wheel intensity tool.Prior art medium plain emery wheel back of the body dish is provided with groove, and groove matches with boss on the grinding spindle ring flange, during work, provides driving force by main shaft to emery wheel, by groove with cooperating of boss emery wheel is rotated on the ring flange.But, because the groove outer rim on the emery wheel back of the body dish is bigger than normal with the boss fit clearance of bistrique ring flange, cause the fastening bolt of connection emery wheel back of the body dish and ring flange stressed often, cause on the emery wheel back of the body dish the impaired or bolt of screw to fracture, make emery wheel break away from grinding spindle, cause the accident.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, connect reliable, novel rail reconditioning emery wheel safe in utilization.
In order to solve the problems of the technologies described above, a kind of novel rail reconditioning emery wheel of the utility model comprises emery wheel body, emery wheel back of the body dish, evenly is provided with cone boss on the described emery wheel back of the body dish, and described cone boss matches with bistrique ring flange corresponding grooves respectively.
Above-mentioned a kind of novel rail reconditioning emery wheel, wherein, the tapering of described cone boss is 1: 30.
Above-mentioned a kind of novel rail reconditioning emery wheel, wherein, described emery wheel back of the body dish is that aluminum alloy materials processes.
The utility model can be realized following beneficial effect:
1, owing to evenly be provided with cone boss on the described emery wheel back of the body dish, the groove on cone boss and the grinding spindle ring flange closely cooperates, and utilizes the compactness principle of cone match, reduces the deviation of the axiality of emery wheel and grinding spindle.Connect fastening after, bolt can not be subjected to the driving force from bistrique, can not bear the rough reaction impulsive force of invar rail yet.During work,, avoided bolt to damage because of driving force by the cone boss transmission of drive force, thereby, improved the reliability that emery wheel uses, and made emery wheel back of the body dish more firm with being connected of main shaft.In addition, the utility model is simple in structure.
2, because the tapering of described cone boss is 1: 30, thereby, make the processing of emery wheel back of the body dish more convenient, and made things convenient for the installation of bolt.
3, because described emery wheel back of the body dish is that aluminum alloy materials processes, not only reduced the weight of emery wheel, made things convenient for transportation, and saved cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view of the utility model A-A.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of novel rail reconditioning emery wheel of the utility model comprises emery wheel body 1, emery wheel back of the body dish 2, evenly is provided with cone boss 3 on the described emery wheel back of the body dish 2.During connection, described cone boss 3 matches with bistrique ring flange corresponding grooves respectively.Cone boss is provided with screwed hole, during connection, by securing member such as bolt emery wheel back of the body dish 2 is fixedlyed connected with the bistrique ring flange and to be integral.Match with the bistrique flange concave by cone boss, can reduce the deviation of the axiality of emery wheel and grinding spindle, connect fastening after, bolt can not be subjected to the driving force from bistrique, can not bear the rough reaction impulsive force of invar rail yet.Thereby, improved the reliability that emery wheel uses, and made emery wheel back of the body dish more firm with being connected of main shaft.Preferred cone boss tapering be 1: 30 because the tapering of described cone boss is 1: 30, thereby, make the processing of emery wheel back of the body dish more convenient, and made things convenient for the installation of bolt.The Material Processing of emery wheel back of the body dish is unrestricted, in the present embodiment, in order to save cost, described emery wheel back of the body dish 2 can be processed by aluminum alloy materials.
In sum, the utility model compared with prior art, have simple in structure, connect reliable, advantage safe in utilization and with low cost.
The utility model is not limited to the scope that the foregoing description is described, and the technical scheme that the means that all employing equivalences are replaced obtain is all in the scope of the utility model protection.
