Soldering tool of connecting piece of battery cooling plate and pipe dowel pin for new energy automobiles

Abstract

The invention discloses a soldering tool of a connecting piece of a battery cooling plate and a pipe dowel pin for new energy automobiles. The soldering tool comprises a tool support base, wherein a pipe dowel pin support base and a connecting piece support base are separately arranged at the upper end and the lower end of the tool support base; an included angle of 10 degrees to 30 degrees is formed by the pipe dowel pin support base and the connecting piece support base; a pipe dowel pin positioning sleeve and a fastening piece positioning sleeve are detachably connected with the pipe dowelpin support base, the lower ends of the pipe dowel pin positioning sleeve and the fastening piece positioning sleeve are separately detachably connected with a pipe dowel pin and a fastening piece, and the pipe dowel pin and the fastening piece are required to be welded; and one end, fixed to the tool support base, of the connecting piece support base and one suspended end are separately providedwith a rear-end positioning module and a front-end positioning module, and the rear-end positioning module and the front-end positioning module are used for positioning the connecting piece. Accordingto the soldering tool of the connecting piece of the battery cooling plate and the pipe dowel pin for the new energy automobiles disclosed the invention, vertical positioning of a connecting pipe anda fastening piece on the connecting piece can be realized, and then the connecting pipe is fixed to the fastening piece through a gravity effect of the positioning sleeve, so that the defect of the prior art is overcome.

Description

Technical field [0001] The invention relates to the technical field of battery cooling for new energy vehicles, in particular to a new energy vehicle battery cooling plate connector and pipe pin brazing tooling. Background technique [0002] As people pay more and more attention to environmental and energy issues, new energy vehicles have become the general trend of the development of the automotive industry today, and the development speed has been very rapid in recent years. [0003] Currently, most new energy vehicles use lithium electronic batteries as their power source. When the car is running at high speed, the power battery will generate a lot of heat, which requires a cooling system in the battery box. The current mainstream cooling systems mainly include battery cooling plate (Cooling plate), battery cooler (Chiller) and indirect condenser (iCond), etc., all of which are brazed aluminum structures. [0004] According to the current domestic technological level, the connec...

AI Technical Summary

Problems solved by technology

[0006] 1. The connection between the connecting pipe and the fastener and the cooling unit is non-vertical, and there is a certain angle, and there is a tolerance gap between the connecting pipe and the connecting piece, and between the fastener and the connecting piece, which makes it difficult to fix the connecting pipe, fastener and welding material;

[0007] 2. Even if the conventional tooling and brazing frame are used to fix each component in place before entering the furnace, since the workpiece is affected by the vibration and gravity of the conveyor belt after entering the furnace, although the gap between the baffle plate and the cooling unit, the connecting piece and the cooling unit The welding seam is well formed, but the connecting pipe and fasteners are very easy to deform, and the size is difficult to guarantee;

[0008] 3. Even if the cooling plate assembly is erected so that the connecting pipe and fasteners are fixed in a vertical state, it is limited by the furnace height when entering the furnace, and it will also affect the formation of other welds

[0010] However, the current technological level can only realize the simple fixing of the connecting parts, and cannot accurately locate the positions of the nozzles and fasteners, and can only be used for general manual flame welding. The welding quality is greatly affected by the welder's operation level, and the production efficiency is very low.
