Embodiment Construction

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

[0024] The pre-welding tooling of the present invention includes a water support tray, a first adjustable support rod for positioning the four-way valve body, and a second adjustable support rod for positioning copper pipes. The first adjustable support rod and the The top of the second adjustable support bar is provided with a clamping end for clamping the object to be welded. A turntable and a submersible pump are installed in the water support tray. The turntable is fixed on the bottom of the water support tray through a bearing, and the bearing is higher than The water surface position of the water tray, the water discharged from the water delivery pipe of the submersible pump is used to cool the welding point, the bases of the first adjustable support rod and the second adjustable support rod are placed on the turntable, and the first adjustable support r...

Abstract

The invention relates to a four-way valve component pre-welding tool capable of general use. The tool comprises a water carrying tray, a first adjustable supporting rod used for locating a four-way valve body and a second adjustable supporting rod used for locating a copper pipe, wherein clamping ends used for clamping welded objects are arranged at the top of the first adjustable supporting rod and the top of the second adjustable supporting rod, a rotating disk is installed in the water carrying tray, the rotating disk is fixed at the bottom of the water carrying tray through a bearing, a base of the first adjustable supporting rod and a base of the second adjustable supporting rod are placed on the rotating disk, the clamping end of the first adjustable supporting rod is a clamping groove of the valve body, the clamping groove of the valve body is detachable and matched with the four-way valve body, the clamping end of the second adjustable supporting rod is a clamping groove of the copper pipe, and the clamping groove of the copper pipe is detachable and matched with the copper pipe. The problems that an existing welding tool can not be applicable to four-way valve components different in size and is complicate in structure and not convenient to use are solved.

Description

technical field [0001] The invention relates to refrigeration fittings, in particular to a pre-welding tooling for four-way valve assemblies of different sizes. Background technique [0002] The four-way valve is widely used in various electrical appliances. For example, the four-way valve in the air conditioner is used for cooling and heating conversion. The welding quality of the four-way valve of the outdoor unit directly affects the efficiency, noise and vibration of the piping. . Through on-the-spot investigation and research on many refrigeration equipment manufacturers (such as central air conditioners, heat pump water heaters), we found that many enterprises need to weld refrigeration components: copper pipes and four-way valves in the production process to form pre-welded components. [0003] In a patent document 1 with the application number of 200820189395.4, an adjustable welding tool is disclosed. The welding tool is used for a valve body that needs to be subm...
