Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] look first figure 1 , figure 1 It shows the three-dimensional schematic view of the assembly welding tool of the present invention when used on the ZOCT side frame 1, and it can be seen that the assembly welding tool of the present invention constrains several important dimensions of the ZOCT side frame 1 from all directions. Wherein, the support seat plate 2 is an accessory to be assembled and welded on the ZOCT type side frame 1, and two support seat plates 2 must be assembled and welded on a ZOCT type side frame 1. The positioning pin 3 is used to locate the supporting seat plate 2 on the tooling main body 4, so as to prevent the supporting seat plate 2 from sliding during the welding process, resulting in unqualified assembly welding.

Abstract

The invention provides a ZOCT type bogie side frame cross-bearing installing base assembly welding tool comprising a tool body (4) with a square tube structure. Two locating and clamping bases (6) are arranged on the tool body (4). Each locating and clamping base (6) is provided with a locating pin (3) which fixes a support base plate (2) of a ZOCT type side frame (1) on the corresponding locating and clamping base (6). The tool body (4) is also provided with first locating bases (5) used for determining the distance between the support base plates (2) and the top surface of the side frame, second locating bases (11) used for location and centering, and third locating bases (7) used for location assisting. The assembly welding tool restrains several crucial dimensions of cross-bearing installing bases, thereby guaranteeing that the position and the dimensions of the cross-bearing installing base meet the requirement of drawings. The tool structure is simplified and the operation is simpler. The location is direct and adjustable location.

Description

technical field [0001] The invention relates to the technical field of vehicle bogies, in particular to a ZOCT type bogie side frame welding tool. Background technique [0002] The ZOCT bogie side frame 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 side frame itself should meet the relevant requirements, its processing size should also meet the requirements of the drawings. The quality of the assembly and welding of the cross support mounting seat is directly related to the quality of the subsequent four-link structure, which in turn affects the completion of the bogie. If the welding size of the cross support mount is out of tolerance, the cross bar will not be assembled. Therefore, special assembly and welding equipment is a necessary condition to ensure its quality. Contents of the invention [0003] The purpo...
