The grinding pulling plate can be adjusted according to the requirements of the axles with different types so as to be adapted to the grinding of the axles with the different types. The grinding pulling plate of the freight car axle comprises a base plate of pulling plate, which is fixedly connected with a grinding machine by a bolt; a plurality of slide grooves are formed in the base plate of the pulling plate; a plurality of slide blocks are arranged on the slide grooves by adjusting assemblies; the slide blocks are fixedly provided with pulling head assemblies. The grinding pulling plate of the freight car axle has the advantages that 1 the design is reasonable and the structure is simple and completely practical; 2 when the divided circles of three screw holes in the axle end of the axle are changed, the corresponding pulling plate does not need to be produced again so that the production efficiency is improved; 3 when the divided circles of the three screw holes in the axle end of the axle are changed, the corresponding pulling plate does not need to be produced again so that the production cost is reduced; 4 when the divided circles of the three screw holes in the axle end of the axle are changed, the mounting and debugging time spent on reproducing a previous pulling plate is shortened and the production period is shortened.
Description
Technical field
The utility model relates to a kind of striking gear that goods train vehicle axle grinding is stirred axletree rotation, relates in particular to a kind of lorry axle grinding driver plate, and this device can need to be adjusted according to the axletree of different model, to adapt to the grinding of various axletree.
Background technology
Existing axletree processing technology, axletree is by three bolts hole that are arranged on driver plate on grinding machine and stir axle shaft end, axletree to be rotated when grinding, the high speed slowly running with emery wheel by axletree relatively rotates carries out grinding to axletree, so on driver plate, the reference circle size of three shifting blocks has determined bolts at axle end hole reference circle size that can grinding axletree.
Development along with railway, the kind of railway freight car products is more and more, particularly export vehicle formula various, corresponding lorry axle is also inevitably different along with the variation of each vehicle, when three bolt hole reference circles of axle head of axletree change, when carrying out axle grinding, just need to again make new driver plate, affect production efficiency and increased production cost, therefore design and produce a driver plate that shifting block reference circle is adjustable, it is necessary can adapting to various axle grinding.
Existing axletree processing technology, when axle grinding, on grinding machine driver plate, the reference circle of three shifting blocks is all fixed, the axletree of the model that a kind of driver plate is can only grinding corresponding with it.There is following shortcoming:
1, the only production of applicable a kind of product of existing fixedly reference circle driver plate, the inadaptable change of product frequently;
2, change product and add and need again make corresponding driver plate man-hour, its fabrication cycle is long;
3, change product and add and need again make corresponding driver plate man-hour, need to increase cost of manufacture;
4, need to reinstall after having made, debugging cycle is longer.
Utility model content
The utility model is mainly to solve the existing difference of the reference circle due to different axletrees of prior art, adds the fabrication cycle that need again make driver plate man-hour and cause long, the technical problem that production cost is high; Provide a kind of simple in structure, cost is low, and can fast adjust different lorry axle reference circle sizes so that a kind of lorry axle grinding driver plate of fast remodeling and producing of railway freight-car.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
An axle grinding driver plate, is characterized in that, comprises a driver plate chassis being fixedly connected with grinding machine by bolt; Described driver plate chassis is provided with some chutes, and some slide blocks are arranged on chute by adjusting part; On described slide block, be fixed with shifting block assembly.
At above-mentioned a kind of lorry axle grinding driver plate, described slide block is provided with a regulating tank, described regulating tank two ends are arc, described adjusting part comprises a socket cap screw and a spring washer, and socket cap screw is successively through after the screw hole on spring washer, regulating tank and driver plate chassis, slide block being fixed on driver plate chassis.
At above-mentioned a kind of lorry axle grinding driver plate, described shifting block assembly comprises a cylinder that is fixed on slide block one end and an end opening and has a cavity, the cavity bottom of described cylinder is placed with pad, pad is provided with cylindroid helical-coil compression spring, and cylindroid helical-coil compression spring top is provided with the straight pin that its bottom contacts with cylindroid helical-coil compression spring top; The inwall of described cylinder opening part is provided with a snap ring, and straight pin bottom outer wall is provided with a retainer ring adapting with snap ring and makes straight pin can in cavity, move up and down and can not skid off outside cavity.
At above-mentioned a kind of lorry axle grinding driver plate, described slide block is three, be radially arranged on driver plate chassis, and the radially angle of two slide blocks all equates.
Therefore, the utlity model has following advantage: 1, reasonable in design, simple in structure and completely practical; 2, when the reference circle of axle shaft end three screws changes, do not need again to make corresponding driver plate, improved production efficiency; 3, when the reference circle of axle shaft end three screws changes, do not need again to make corresponding driver plate, reduced production cost; 4, when the reference circle of axle shaft end three screws changes, shorten installation, debug time after former fixedly driver plate is made again, shortened the production cycle.
