Description

Auxiliary tool for machining heat exchanger fins

Technical Field

The utility model relates to a technical field of machine tooling specifically is an auxiliary fixtures of heat exchanger fin processing.

Background

When the heat exchanger fins are machined, inclined hole drilling and outer contour machining are needed, the fins need to be stacked firstly in the existing machining method, then inclined hole drilling is conducted on a rocker arm drilling machine, the stacked fins are conveyed to a machining center or a milling machine to conduct outer contour machining, the method repeatedly conveys blanks to replace equipment for machining, the working strength of workers is increased, and machining efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, namely the problems in the prior art, the utility model provides an auxiliary tool for machining heat exchanger fins, which comprises a mould for placing a workpiece, wherein the mould is arranged on a workbench, a plurality of equal-height blocks for cushioning the workpiece are arranged above the mould, a plurality of first positioning clamps for positioning and clamping the outer contour of the workpiece are arranged around the upper part of the mould, and a plurality of second positioning clamps for positioning and clamping the through holes of the workpiece are arranged in the middle of the upper part of the mould;

the mould is including being used for being connected fixed bottom plate, the roof that is used for placing the work piece and a plurality of pillars that are used for supporting the roof with the workstation, the bottom plate is installed on machining center's workstation, the bottom plate slope is fixed on the bottom plate, both ends are fixed continuous with roof and bottom plate respectively about the pillar, the contained angle between roof and the bottom plate is 6 degrees to 15 degrees.

The utility model discloses a further set up to: the first positioning clamp is an L-shaped clamp.

The utility model has the advantages that: through the auxiliary fixtures who designs, make the blank slope lift up, need not to use radial drill, also can carry out the operation of boring the inclined hole in machining center, make the processing of boring the inclined hole process more convenient, high piece makes blank by high unsettled pad of height piece, make the bottom plate can not damage because of drilling processing, the step of changing the bottom plate has been saved, the cost of processing has been reduced, the processing of two processes can be carried out at same equipment machinery simultaneously, need not to remove the processing that the blank accomplished two processes, and need not the relocation, and the work efficiency is increased, positioning accuracy and machining precision have been increased, the quality of product has been improved, the assembly precision in later stage has been guaranteed.
