Embodiment Construction

[0015] see figure 1 , figure 2 and image 3 An electric locomotive roof assembly welding tool, including an overall frame, a gantry and a cylinder, the overall frame in the roof assembly welding tool is composed of evenly distributed reinforcing ribs 1, four main beams 2, two square tubes Side beams 3, a bottom plate 4 and two side wall panels 5 form a concave frame structure;

[0016] Four main beams 2 and two cross bars 14 form a well-shaped underframe. Square tube side beams 3 are arranged on both sides of the underframe. A bottom plate 4 is arranged on the underframe. The lower surface of the bottom plate 4 is provided with evenly distributed reinforcing ribs. 1. That is, the bottom plate 4 is a whole steel plate with a thickness of 20 mm, which is placed parallel to the stiffener plate 1 and fixed by spot welding to ensure a flatness of 0.5 mm, and at the same time ensure that the plane cannot be distorted. The whole steel plate is used to ensure the flatness of the b...

Abstract

The invention relates to an electric locomotive roof assembly and welding tool, which comprises an integral frame, a gantry and a cylinder, wherein the integral frame consists of a reinforcing ribbed plate, a main beam, an edge beam, a bottom plate and a side wall board; the side wall board and the bottom plate form an inclination angle; a sliding track for mounting the gantry is arranged outside the side wall board; the gantry is provided with a movable cylinder fixing frame and is used for eliminating welding gap between an aluminum plate and the frame to guarantee welding quality; and the effect of reducing welding deformation is reduced by forming rigid fixing force for the aluminum plate and the frame. Side wall pressing cantilevers are uniformly distributed outside the edge beam; and the reinforcing ribbed plate is provided with a positioner connecting pipe. The interference between a product and the tool is eliminated in a movable pressing and fixed pressing combined mode, so that all products can be welded on the tool at one time. The working efficiency is increased. All positioning devices are used for quick and accurate positioning. The stability of the tool is effectively guaranteed, and the product quality requirements are met.

Description

Technical field: [0001] The invention relates to a welding tool for the top cover of an electric locomotive to ensure the quality of the welding seam and the appearance structure of the product; it belongs to the field of mechanical manufacturing. Background technique: [0002] During the manufacture of the existing top cover tooling, it is easy to have poor rigidity and sinking and deflection of the tooling, which will cause the tooling to fail. The deformation of the used fixtures, positioning blocks and other devices due to welding; there is a contradiction between the practicability and flexibility of the clamping method. It is difficult to grasp the welding deformation characteristics of the positioning block and positioning reference of the product. So that the location of the positioning is not positioned in the actual application process. Empirical data is not verified by experiments or errors are not obtained during experiments to obtain true and accurate data. U...
