Problems solved by technology

However, the test results are often disappointing. The reason is that the reliability of the positioning method of drilling holes is poor, resulting in the processing of the supercharged flange connection holes. Inconsistent with the drawing design, affecting engine performance
At present, although there are high-efficiency CNC machine tools or machining centers, such processing equipment still does not have suitable supporting fixtures to achieve fast and accurate positioning. If imported laser scanning devices with a price of more than 100,000 yuan are used, it will inevitably lead to Increased processing costs

specific Embodiment 1

[0030] Such as figure 1 , figure 2 and image 3 As shown, a positioning device for the connection hole of the exhaust manifold pressurized flange, including a clamp body, a fixed core tire positioning mechanism is arranged on the base plate 1 of the clamp body, and the base plate 1 of the clamp body is connected to the workpiece through a three-axis moving mechanism Install splint 2.

[0031] The workpiece clamping plate 2 is provided with a positioning plane 3 for positioning the inlet flange of the exhaust manifold on the side away from the fixed core tire positioning mechanism, and two or three positioning planes are provided on the positioning plane 3 for initial Locate the dowel pin 4 for the intake port of the exhaust manifold.

[0032] The three-axis moving mechanism includes an elevating member 7 arranged at the lower part of the workpiece clamping plate, an X axis on the upper part of the elevating member 7, and a Y guide axis perpendicular to the X axis in a hori...

specific Embodiment 2

[0049] The difference from Embodiment 1 is that the Y-direction locking mechanism includes several positioning holes and matching set bolts and fasteners provided on the bottom plate of the clamp body.

specific Embodiment 3

[0050] The difference from the specific embodiment 1 or 2 is that the X-direction locking mechanism and the Y-direction locking mechanism are arranged in three groups and four groups respectively.

[0051] In the above-mentioned embodiment, the exhaust manifold supercharging flange connection hole positioning device and the drilling positioning method of the present invention use the positioning planes of several flange faces parallel to the intake end of the exhaust manifold as the first positioning reference. The exhaust manifold is close to the positioning plane, and the initial reference positioning is performed through the positioning pin. The size of the positioning pin is obviously smaller than the size of the air inlet. At this time, the exhaust manifold flange It has a certain tendency to lean forward. The design of the clamp body itself is based on the position of the end face of the workpiece pressurized flange. After the initial positioning, the distance of free mov...

Abstract

The invention discloses an exhaust manifold pressurization flange connecting hole locating device which comprises a clamp body. A fixed type elastic core tire body is arranged on a base plate of the clamp body, and the base plate is connected with a workpiece clamping plate through a three-shaft moving mechanism. According to the exhaust manifold pressurization flange connecting hole locating device, a locating pin is used for carrying out initial reference locating, the workpiece clamping plate and an exhaust manifold are lifted in the Z direction through a lifting construction member, sliding guide rails on a Y guide rail shaft and an X shaft carry out forced movement, the position of an air outlet of the exhaust manifold is corrected, the exhaust manifold continues to be lifted to an upper press plate to be attached to a pressurization flange face and be hovered, the fact that the exhaust manifold pressurization flange face is level is achieved, locking of the exhaust manifold pressurization flange face in the Z direction is ensured, three-direction locating locking of the pressurization flange face is finally achieved, hole drilling of a pressurization flange connecting hole is lastly achieved, and chamfering and tapping are carried out. Due to the adoption of the technical scheme, location precision and quality of hole drilling are reliably ensured, and large-scale production of hole drilling machining of all kinds of exhaust manifold pressurization flanges is convenient to achieve.

Description

technical field [0001] The invention belongs to the technical field of automobile engine production, and in particular relates to a positioning device and a drilling positioning method for an exhaust manifold supercharging flange connection hole. Background technique [0002] The exhaust manifold is an important supporting component of the exhaust system of the automobile engine. Its structure usually has an intake air passage corresponding to the exhaust port of the cylinder of the automobile engine. It is connected to the engine block through connecting bolts; the air outlet is connected to the supercharger through the gas outlet flange, and the supercharger is externally connected to the exhaust manifold. The main functional requirement of the exhaust system is to discharge the exhaust gas in the cylinder to the atmosphere through the exhaust manifold, exhaust manifold, catalytic converter and muffler with as little exhaust resistance and noise as possible. Therefore, in...
