Embodiment

[0028] like figure 1 , figure 2 and image 3As shown in the figure, an engine cooling slant hole detection tool is specially used for the slant hole detection of an engine block adopting a double cooling slant hole cooling method. On the engine block 12, there are two cooling slant holes communicating with each other at the bottom as the flow channel of the coolant. The design requires that the diameter of the slant holes is between 2.9mm and 3.0mm, and the inclination angles of the two slant holes are respectively 36° and 38°, the depth of the 36° oblique hole is 36mm to 37mm, and the depth of the 38° oblique hole is 37mm to 38mm. The engine cooling oblique hole detection tool includes a measuring stick 1 and an angle block 2. The measuring stick 1 and the angle block 2 are detachably connected. In this embodiment, it is specifically a composite connection method of sliding socket and screw connection. The measuring rod 1 includes an oblique hole through-end detec...

Abstract

The invention provides an engine cooling inclined hole detection tool which comprises a measuring stick and an angular gauge block. The measuring stick and the angular gauge block are movably connected in a detachable mode. The measuring stick comprises an inclined hole go end detection segment and an inclined hole not-go end detection segment. The diameters of the inclined hole go end detection segment and the inclined hole not-go end detection segment are respectively equal to a machining upper limit value and a machining lower limit value of the hole diameter of the engine cooling inclined hole. A first inclined plane and a second inclined plane are arranged on the angular gauge block. After the measuring stick and the angular gauge block are connected, included angles between the first inclined plane and the measuring stick and between the second inclined plane and the measuring stick are respectively equal to dip angles of two cooling inclined holes in a cylinder body. Meanwhile, further provided is a detection method and the method is based on the engine cooling inclined hole detection tool. The engine cooling inclined hole detection tool is high in functional integration level and detection efficiency, and low in detection cost.

Description

technical field [0001] The invention relates to an engine inspection tool and a related inspection method, more specifically, it relates to an engine cooling slant hole inspection tool and a detection method for the engine cooling slant hole using the tool. Background technique [0002] In order to increase the cooling effect of the direct injection engine in the cylinder, some automobile engine production units now use double cooling slant holes to implement the cooling between the cylinder water jacket and the cylinder, that is, two small diameter slant holes intersecting at the bottom are set on the engine block. The coolant is passed inside, and the two inclined holes usually have the same diameter, but each has its own depth and inclination requirements. Since the three parameters of the diameter, depth and angle of the inclined hole have a direct impact on the cooling effect of the inclined hole, strict inspection is required to control the diameter, depth and angle of...
