根据铁道部规定,新造60吨以上货车一律装用13号车钩,50吨货车应逐步改用13号车钩。我校机械制造专业教研组受戚墅堰机车车辆工厂的委托,设计、制造了一台13号车钩钩体尾部平面加工专用铣床,其外形如图所示。该专用铣床经实际使用,性能符合设计要求,在提高13号车钩的产量和质量方面发挥了一定作用。 According to the regulations of the Ministry of Railways, all new trucks with a capacity of 60 tons or more should be equipped with No. 13 coupler and the 50-ton truck should be gradually converted to No. 13 coupler. Our school mechanical manufacturing professional teaching and research group by Qishuyan rolling stock factory commissioned a design, manufacture of a 13 hook body tail plane milling machine, its shape as shown. The practical use of the milling machine, the performance meets the design requirements, to improve the production and quality of the No. 13 coupler played a role.
