Problems solved by technology
This method of processing and positioning is not only inefficient and unable to meet the needs of large-scale industrial production of exhaust manifolds, but also the accuracy of the drilling position is often difficult to guarantee due to the swing of the drill bit, resulting in large errors and low pass rate.
At present, although there are high-efficiency CNC machine tools or machining centers, such processing equipment is not only expensive, but also must be equipped with imported laser scanning devices that cost more than 100,000 yuan, resulting in increased processing costs.

The invention discloses a drilling positioning device and a drilling positioning method of a double-tire exhaust manifold air inlet flange. The drilling positioning device is provided with a clamp body; a positioning drill template is arranged at the top of the clamp body; a positioning plane for positioning an exhaust manifold standard surface is arranged at the bottom of the positioning drill template; the positioning drill template is provided with a drilling positioning tire and a drilling mould hole; and at least two sets of workpiece clamping mechanisms are arranged below the positioning drill template. The drilling positioning method comprises the step of taking two air inlets of an exhaust manifold as positioning standards, wherein one air inlet is positioned by four points and the other air inlet is positioned by two points. According to the drilling positioning device and the drilling positioning method disclosed by the invention, the accurate positioning of the exhaust manifold air inlet flange can be realized, the drilling quality is reliably guaranteed and the scale production of drilling machining of various exhaust manifold air inlet flanges is realized by using a simpler positioning device. The drilling positioning device has the advantages of simple structure, low construction cost, convenience for operation and the like.
Description
Technical field [0001] The invention belongs to the technical field of automobile engine production, in particular to a drilling positioning device and a drilling positioning method for an intake flange of a twin-tyre exhaust manifold. Background technique [0002] The exhaust manifold is an important supporting component of the automobile engine exhaust system. Its structure usually has an intake air passage corresponding to the exhaust port of the automobile engine cylinder. The intake port is equipped with an intake flange, and each intake flange It is connected with the engine cylinder by connecting bolts; the air outlet is connected with the turbocharger through an air outlet flange, and the turbocharger is connected with an exhaust manifold. The main functional requirement of the exhaust system is to discharge the exhaust gas in the cylinder into the atmosphere through the exhaust manifold, exhaust manifold, catalytic converter, and muffler with as little exhaust resistance...
