Abstract

The invention discloses a detection tool for the fuel injection pump bracket of an engine. The detection tool comprises a measuring seat provided with a bottom plate and a side plate, a clamping mechanism and an auxiliary core shaft. The side plate is provided with two positioning pins corresponding to two positioning pin holes in the fuel injection pump bracket. The clamping mechanism is used for fixing the fuel injection pump bracket on the side plate. The diameter of the auxiliary core shaft is the same with the diameter of the inner arc surface of the fuel injection pump bracket. When the auxiliary core shaft is supported on the inner arc surface, the axis of the auxiliary core shaft and the axis of the inner arc surface are in the same line. According to the technical scheme of the invention, two important positioning dimensions of the fuel injection pump bracket can be measured by means of a height gauge only through one-shot clamping process. Therefore, the detection tool is convenient and efficient in measurement, and accurate in measurement result.

Description

technical field [0001] The invention relates to the field of engine fuel injection pump brackets, in particular to a detection tool for the engine fuel injection pump bracket. Background technique [0002] The fuel injection pump of the engine needs to be set on the cylinder block through the fuel injection pump bracket, such as figure 1 and figure 2 As shown, the top surface of the fuel injection pump bracket 1 is provided with an inner arc surface 11 for supporting the fuel injection pump, and the side of the fuel injection pump bracket 1 is provided with a positioning pin hole 12 and a mounting hole 13 . The inner arc surface 11 has two important positioning dimensions, one is the distance a between the center of the inner arc surface 11 and the side surface, and the other is the distance between the center of the inner arc surface 11 and the center line of the positioning pin hole 12 b. [0003] When inspecting the engine fuel injection pump bracket 1, the two positi...
