Engine cylinder head combination fixture processing jig and application method thereof

Abstract

The invention relates to an engine cylinder head combination fixture processing jig which can clamp and process multiple engine cylinder heads at one time, can quickly and accurately clamp the enginecylinder heads in place and is easy to operate and an application method thereof. A middle die plate and an upper die plate are arranged at the upper end of a base by virtue of multiple columns of upright posts; multiple groups of guiding double sliding blocks are longitudinally arranged on the upper end face of the middle die plate, and one hydraulic lifting tray is arranged between each group ofguiding double sliding blocks; multiple hydraulic lifting platforms are arranged on the upper end face of the base, lifting rods of the hydraulic lifting platforms pass through the middle die plate,then the upper end faces of the lifting rods are fixedly connected with the lower end faces of corresponding hydraulic lifting trays; and multiple square holes are formed in the upper end face of theupper die plate, and multiple dowel holes are formed in the upper end face of the upper die plate. The engine cylinder head combination fixture processing jig provided by the invention has the advantages that firstly the engine cylinder head combination fixture processing jig saves both labor and time when in use, and production quality and production efficiency can be greatly improved; and secondly, the engine cylinder head combination fixture processing jig adopts a one-surface and two-pin manner for locating and clamping the engine cylinder heads, so that the engine cylinder heads can be quickly and accurately clamped.

Description

technical field [0001] The invention relates to an engine cylinder head combination jig processing tool mold which can not only clamp and process multiple engine cylinder heads at one time, but also has fast, accurate and in-place clamping and convenient operation, and belongs to engine Cylinder head fixture manufacturing field. Background technique [0002] The engine cylinder head is an important part of the engine, and an important index to measure the quality of the engine cylinder head is the error of the multiple sets of cylinder head seat ring holes and cylinder head conduit holes opened in the engine cylinder head (such as a set of cylinder head seat ring holes and cylinder head duct holes and their respective roundness and coaxiality between the two, the accuracy of vectors between adjacent cylinder head seat ring holes and cylinder head duct holes), the existing engine cylinder head is installed with a hand-held tool, Clamp. Its disadvantages: First, the hand-hel...

AI Technical Summary

Problems solved by technology

Its disadvantages: First, the hand-held installation and pressing force is uneven at each point of the workpiece. If the loading is not in place, the workpiece swings and the tool hits the knife during processing; the second is that the workpiece is loaded unevenly and deflected. The size error of the processing hole position is large, and the accuracy of the processing position is difficult to guarantee; the third is that the independent process of the workpiece processing clamping and conversion is labor-intensive, time-consuming, high scrap rate, and low production efficiency
