Problems solved by technology

This method has the following disadvantages: on the one hand, since the engraving device and the grinding wheel spindle use the same kinematic mechanism, grinding, testing and serial number engraving are processed sequentially, and the engraving processing time accounts for about 15% of the total track manufacturing time, so This causes the waiting of the grinding device and prolongs the processing time; on the other hand, since the state of the rail surface cannot be measured before engraving, the font of the serial number will appear in different shades during the engraving process, which is poor in aesthetics and will also Causes the engraving tool to wear out too quickly

Embodiment 1

[0023] Refer to the attached figure 1 , the invention discloses a high-efficiency processing method for ballastless track plate serial number. After the track plate is ground by the grinding device and passed the inspection, it is transported to the bottom of the independent three-coordinate engraving unit 1 by a conveying trolley, and the contact in the engraving unit The measuring device actually measures the engraving position on the track plate, analyzes and calculates the measurement data by the automatic programming software, and automatically compiles the engraving processing program for the track plate serial number according to the track plate serial number transmitted by the grinding station; engraving The processing program automatically controls each servo motion axis through the CNC system of the grinding machine 5 to complete the processing of the track plate serial number; after the track plate serial number is engraved, the track plate is transported to the sub...

Embodiment 2

[0025] On the basis of Example 1, as a preferred embodiment of the present invention, refer to the attached image 3 The independent three-coordinate engraving unit of the present invention includes two groups of longitudinal beams 1, a crossbeam 7 supported on the two groups of longitudinal beams 1 and moving along the length direction of the track slab, supported on the crossbeam 7 and moving along the width of the track slab The vertical carriage 2 that moves in the direction, the engraving main shaft 5 that is arranged on the end of the vertical carriage 2 and moves vertically up and down, is supported on the vertical carriage 2 and is positioned at the contact measuring device of the engraving main shaft 5 side; The touch measuring device includes a touch measuring head 4 for actually measuring the engraving position on the track plate, and a vertical feed mechanism 3 for making the touch measuring head 4 move vertically up and down. Through the independent three-coordina...

Abstract

The invention discloses a method for machining serial numbers of a ballastless track plate efficiently, and relates to the technical field of the machining of CRTSII ballastless track plates required in high-speed railroad construction. In the method, the carving, grinding and detection of the serial numbers of the track plate are performed synchronous by using an independent carving device, so the production efficiency of the track plate is improved; and the serial numbers of the track plate machined by the method are uniform in depth and attractive in appearance, and the service life of cutters for carving is prolonged.

Description

[0001] technical field [0002] The invention relates to the technical field of processing CRTSII ballastless track slabs required in high-speed railway construction, in particular to a method for processing serial numbers of CRTSII ballastless track slabs. Background technique [0003] At present, in the construction of high-speed railways with a speed of 350Km per hour, the CRTSII ballastless track system is widely used. The key core is to use high-precision CNC track slab grinder to grind and engrave each track slab bearing platform in the railway line design. serial number. Since track slabs are the foundation of railway construction, efficient manufacturing of track slabs has become an urgent problem to be solved in the development of high-speed railways. [0004] At present, when CRTSII track slab manufacturing enterprises at home and abroad produce CRTSII ballastless track slabs, the track slab serial numbers that have been ground and passed the inspection all adopt ...
