垫板钻孔用气动夹具设计

Design of Pneumatic Fixture for Plate Drilling

随着铁路货车车辆的高速行驶,货车上下心盘成为车辆的重要连接受力部件之一,心盘的质量与货车配件的疲劳、损坏有直接的关系,针对心盘顶板使用中存在的问题,结合车间实际情况,研制了一种新型气动夹紧装置,投入使用后取得了预期的工作、经济和安全效果。

With the development of high speed railway freight car truck, lower heart disk has become one of the important components of ve- hicle connecting stress, fatigue damage, there is a direct relationship between the quality and the truck accessories center plate, aiming at the existed in core plate roof problems in use, combined with the actual situation of the workshop, has developed a new type of novel pneumatic clamping device, put into use and achieved the desired work, safety and economic effect.
