Locomotive hub grinding device

Abstract

The invention discloses a locomotive hub grinding device. The locomotive hub grinding device comprises a bottom plate, wherein the upper surface of the bottom plate is fixedly connected with two fixedplates; the two fixed plates are separately positioned at left and right sides of the upper surface of the bottom plate; threaded caps are in blocking connection on the side surfaces of the fixed plates; the inner parts of the threaded caps are in threaded connection with threaded studs; and the left ends of the threaded studs are in blocking connection with the right side surfaces of extruding plates through auxiliary devices. According to the locomotive hub grinding device disclosed by the invention, handles are arranged, and a right side blocking block is firstly moved out from a blockingslot, so that a worker rotates the right side handle to drive a rotary plate and the corresponding threaded stud to rotate; under action of the threaded cap at the right side, the threaded stud at theright side moves leftwards to drive a first rotary shaft, a bearing and the extruding plates to move leftwards, so that the two extruding plates can stably clamp a hub, and therefore, the hub does not shake in a grinding process, the grinding effect of the hub is better, working strength of the worker is relieved, and working efficiency of a plant is improved.

Description

technical field [0001] The invention relates to the technical field of locomotive hubs, in particular to a grinding device for locomotive hubs. Background technique [0002] A locomotive is a self-propelled vehicle that pulls or pushes railway vehicles, but does not carry a business load, commonly known as a locomotive. Calculated by the amount of fuel consumed per ton-kilometer, locomotives are the land transportation tools that consume the least energy. [0003] The locomotive hub is an important part of the locomotive. In the production process of the locomotive hub, there will be many burrs on the rough hub. It is an indispensable process for grinding the hub. The traditional method is to put the hub on the deburring The burrs are brushed on the machine. Due to the special shape of the wheel hub, it is not easy to fix the wheel hub on the workbench, so that the grinding machine cannot achieve the desired effect on the wheel hub. In order to increase its pass rate, peopl...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a grinding device for the wheel hub of a locomotive, which solves the problem that the wheel hub is not easy to be fixed on the workbench due to the special shape of the wheel hub, so that the grinding machine cannot achieve the desired effect on the wheel hub grinding. To increase the pass rate, people often need to further grind the wheel hub manually, but manual grinding is not only time-consuming and laborious, but also the dust generated during the grinding process is very harmful to the human body.
