Soldering clamping device for engine oil cooler

Abstract

The invention discloses a soldering clamping device for an engine oil cooler. The device comprises a fixed plate, a bottom plate, a left clamping mechanism, a right clamping mechanism, a lower soldering plate for holding the engine oil cooler, an upper soldering plate arranged on the engine oil cooler, a positioning mechanism, a compacting mechanism, a left profiling mechanism and a right profiling mechanism, wherein the bottom plate is fixed on the fixed plate; the lower soldering plate is arranged on the bottom plate; the left clamping mechanism and the right clamping mechanism are clamped on the lower soldering plate and the upper soldering plate which clamp the engine oil cooler; the left profiling mechanism and the right profiling mechanism adapt to the ends of the engine oil cooler in shape; the positioning mechanism, the compacting mechanism, the left profiling mechanism and the right profiling mechanism are connected with the fixed plate; the positioning mechanism is positioned below the fixed plate; the compacting mechanism is positioned above the fixed plate; and the left profiling mechanism and the right profiling mechanism are positioned on two sides of the compacting mechanism. The soldering clamping device for the engine oil cooler is high in clamping efficiency and can ensure the clamping precision.

Description

technical field [0001] The invention belongs to the technical field of tooling, and in particular relates to a brazing and clamping device for an oil cooler. Background technique [0002] The existing oil cooler includes a chip layer and two flanges welded on the chip layer, the chip layer includes multi-layer chips, copper sheets and spacer rings are arranged between the chips, and the oil cooler There are two large through holes on the device, and two small installation holes on each flange. In order to facilitate the installation of the oil cooler, the multi-layer chips and flanges need to be brazed before being put into the heating furnace. Clamping to ensure the verticality of the multi-layer chip and the positional accuracy of the small mounting holes on the flange. The brazing and clamping device of the oil cooler in the prior art includes left and right clamping mechanisms, which can clamp the chips arranged between the upper brazing plate and the lower brazing plat...

AI Technical Summary

Problems solved by technology

The brazing and clamping device of the oil cooler in the prior art includes left and right clamping mechanisms, which can clamp the chips arranged between the upper brazing plate and the lower brazing plate from the left and right sides layers and flanges, but the left and right clamping mechanisms are manually operated by the operator, and it takes a lot of time to arrange the chips manually to ensure the vertical accuracy of the chip layer, and the clamping efficiency is low; in addition, the left and right clamping mechanisms It only plays the role of clamping the multi-layer chip up and down. The left and right clamping mechanisms are not provided with a cam, which cannot limit the multi-layer chip, so the chip layer is prone to twisting, and it is impossible to guarantee multiple layers when clamping the multi-layer chip. The vertical accuracy and assembly accuracy of the layer chip, because the two small mounting holes of the flange are not positioned, the flange is easy to rotate around the large mounting hole, and the mounting position accuracy of the small mounting hole of the flange cannot be guaranteed, that is, the flange’s position cannot be guaranteed. Clamping accuracy makes it difficult to install the oil cooler after brazing
