Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Look figure 1 , figure 1 It shows the structure schematic diagram of this fixed lever support point assembly welding tool of the present invention. It can be seen from the figure that the tool of the present invention mainly includes the following parts: overall, the tool of the present invention is similar to the structure of an aircraft, and the backbone is A center positioning plate 14, all the other components are attached on the center positioning plate 14. The place ahead of the central positioning plate 14 is a centering plate 13 and a centering pin 12 of the bolster heart plate, which are used for the positioning of the bolster heart plate.

[0019] The tail of the central positioning plate 14 is the tailstock positioning and welding device 7, which is used for positioning the bolster tailstock. The tailstock positioning and w...

Abstract

The invention provides a ZOCT type bogie swing bolster fixing lever fulcrum base assembly welding tool comprising a central location plate (14). A swing bolster center plate centering disc (13) is arranged in front of the central location plate (14). The central location plate (14) is provided with a fixing lever fulcrum base locating plate (9) in the middle and is provided with a groove-shaped tail base locating assembly welding device (7) at the tail portion. A safe lifting base welding device (3) and a swing bolster cross center locating device (6) are arranged between the fixing lever fulcrum base locating plate (9) and the tail base locating assembly welding device (7) successively. The tool also comprises three swing bolster horizontal locating pins (4). The assembly welding tool restrains several crucial dimensions of fixing lever fulcrum bases, eliminates uncertain factors generated by different work pieces through reasonable design and guarantees that the positions and the dimensions of the fixing lever fulcrum bases meet the requirement of drawings.

Description

technical field [0001] The invention relates to the technical field of vehicle bogies, in particular to a ZOCT type bogie bolster fixing lever fulcrum seat assembly welding tool. Background technique [0002] The ZOCT type bogie bolster is one of the main force-bearing parts of the running part of the railway freight car, and it is the key object to ensure the safety of the train. In addition to the physical and chemical properties of the bolster itself should meet the relevant requirements, its processing size should also meet the requirements of the drawings. The quality of the assembly welding of the brake beam safety chain hanger and the fixed lever fulcrum seat is directly related to the installation of the subsequent foundation brake device, which in turn affects the completion of the bogie. If the welding size of the fixed lever fulcrum seat is out of tolerance, the situation that the fixed lever cannot be assembled will occur. Even if it is barely installed, it will...
