The utility model relates to a kind of electric meter circuit board reflow soldering mould, including bottom plate, the front of bottom plate is equipped with the circuit board card slot for circuit board insertion, the periphery outside of circuit board card slot is equipped with the rotatable and the rotating block of compacting circuit board, multiple device slots for electronic component insertion are equipped in circuit board card slot, pin hole for the pin of electronic component insertion is opened in device slot, the back of bottom plate is respectively equipped with baffle corresponding device slot position.This utility model can insert pin type device in advance on circuit board, reflow soldering with other patch type device, that is, all devices can be welded by once reflow soldering of this utility model, greatly simplify the welding process, shorten production cycle.

The present application relates to the technical field of pipeline welding, in particular to a heat pipeline construction butt joint device and method, the device comprises two N-shaped frames, a hydraulic rod is connected between the two N-shaped frames, cams are rotatably connected to the top and both sides of the lower part of the two N-shaped frames, the two N-shaped frames are clamped on a first pipeline and a second pipeline to be butt jointed through the bottom openings, the first pipeline and the second pipeline are centered after the rotation of the cams, the hydraulic rod is shortened to pull the end of the first pipeline and the second pipeline close; a welding gun is arranged between the two N-shaped frames, the welding gun can revolve around the butt joint part of the first pipeline and the second pipeline to weld the first pipeline and the second pipeline; the method comprises centering, welding gap adjustment, welding and removing the device; the present application is convenient to assemble and disassemble, suitable for the construction in narrow space in a groove, simplifies the assembly and welding process, improves the construction efficiency and the welding quality.

The utility model provides a kind of tab welding fixture.The welding fixture includes: bearing plate, first clamping part and second clamping part.The top plane of bearing plate forms the placement position of the battery to be welded;First clamping part is connected with bearing plate, and first clamping part is movably arranged relative to bearing plate along the first direction;Second clamping part is oppositely arranged with first clamping part, and second clamping part is connected with bearing plate;Wherein, first clamping part has the clamping position of moving towards second clamping part to make first clamping part and second clamping part fix the tab of the battery to be welded, and first clamping part has the release position of moving in the direction away from second clamping part to release tab, when first clamping part is in clamping position, the limiting space for fixing the pole piece of the battery to be welded is formed between first clamping part and bearing plate.The present scheme solves the problem of low matching degree of welding equipment in the prior art, thereby affecting the welding quality.

This utility model relates to a dual-flow heat exchanger, comprising: a core; a first end cap assembly fixedly connected to the core; and a second end cap assembly including an inlet pipe, an outlet pipe, a first housing, and a second housing, both the first and second housings being fixedly connected to the core. The inlet pipe is fluidly connected to the second housing, and the outlet pipe is fluidly connected to the first housing, thereby allowing the heat exchange medium to enter through the inlet pipe and exit through the outlet pipe. The dual-flow heat exchanger provided in this application has the advantages of simple structure and easy assembly. Furthermore, the entire welding process of this dual-flow heat exchanger is simple, with no welding blind spots. Compared to the prior art, the dual-flow heat exchanger provided in this application achieves high welding quality and a low product defect rate due to sufficient welding and the absence of welding blind spots.
