However, there is still no comprehensive evaluation of the heat transfer mechanism of the piston in the internal cooling oil chamber. The traditional oil injection cooling test is mainly based on the steady state test, and now the transient test has become a new research hotspot. However, in the coaxial positioning, the accuracy It is not high, and the error is large, which seriously affects the accuracy of the test and the exploration of the heat transfer mechanism of the internal cooling oil cavity piston.

The invention provides a coaxial positioning device for a nozzle and an oil channel. The device comprises the following parts: a base; a worktable, which is arranged above the base; a guide rail, which is arranged between the base and the worktable and used for limiting the movement of the worktable; an adjuster, which is connected with the worktable and used for adjusting the position of the worktable; a grating ruler, which is correspondingly arranged with the adjuster and used for acquiring the displacement signals of the worktable; a display, which is connected with the grating ruler and used for displaying the displacement signals acquired by the grating ruler; a dividing plate, which is arranged above the worktable; and a fixing chuck, which is arranged above the dividing plate and used for clamping and fixing the nozzle. According to the coaxial positioning device for the nozzle and the oil channel, the coaxial positioning of the nozzle and the oil channel is realized, a fuel injection cooling transient test is facilitated, the manual errors are reduced, the whole-process digital adjustment can be achieved, the positioning precision is high, and the working efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of positioning devices, in particular to a coaxial positioning device for a nozzle and an oil passage. Background technique [0002] With the increase of the heat load of the piston, the market of the internal cooling oil chamber piston continues to expand. However, there is still no comprehensive evaluation of the heat transfer mechanism of the piston in the internal cooling oil chamber. The traditional oil injection cooling test is mainly based on the steady state test, and now the transient test has become a new research hotspot. However, in the coaxial positioning, the accuracy It is not high, but the error is large, which seriously affects the accuracy of the test and the exploration of the heat transfer mechanism of the piston in the internal cooling oil chamber. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or...
