Abstract

The invention discloses a grinding machine for a brake valve of a railway vehicle. The grinding machine is characterized in that the whole machine is composed of a main machine body, a workbench, a valve grinding station, shields, a plane grinding station for the upper surface of a slide valve and a plane grinding station for the lower surface of the slide valve; the three stations are composed ofreciprocating motion mechanisms, pressing mechanisms and power transmission mechanisms respectively; each reciprocating motion mechanism is composed of linear guiding rails, a connecting board and agrinding air cylinder which are installed on the workbench, a first sliding board installed on the linear guiding rails, a second crooked board installed on the first sliding board and a hinge pin, anadjustment spring, a pull rod, a drum-shaped hinge pin and combined oil stones which are at the front end of the second crooked board; each pressing mechanism is composed of a second sliding board and a pressing air cylinder base, a pressing air cylinder, a pressing rod support, a pressing rod, a bearing, a reset spring and a reset board which are located on the second sliding board; each power transmission mechanism is composed of a first crooked board, an oscillating rod, first meets and a second meet. The grinding machine is ideal equipment for grinding the brake valve of the railway vehicle.

Description

Technical field [0001] The invention is a device used for grinding the brake valve body of railway vehicle, the upper plane of sliding valve and the lower plane of sliding valve. Background technique [0002] The brake valve is a key component of the railway vehicle braking system. The quality of the brake valve directly affects the braking performance of the vehicle and is related to the safe operation of the vehicle. At present, the maintenance of brake valves is mostly manual grinding, and a small amount of equipment is used for grinding. However, due to unreasonable design and imperfect technology, it is difficult to meet the requirements of production efficiency and grinding quality. The full-function grinding machine for brake valve developed by us adopts the method of moving and pressing at one point and positioning the plane of the workpiece to be ground. , the pass rate is greatly improved, and the production efficiency is also guaranteed.
