Problems solved by technology

[0005] The main purpose of this application is to provide a test fixture for a variety of fuel injectors to solve the problem that the traditional fixture has a single structure. When the angle or center line of the fuel injector changes, the same fixture cannot be clamped. It is only necessary to replace the corresponding fixture, which increases the production cost

Embodiment 1

[0057] The horizontal movement of the clamping block 7 is controlled by rotating the first adjusting screw 8. When the clamping block 7 is separated from the column 2, the height of the oil collector support plate 3 is adjusted, and when the clamping block 7 is close to the column 2, the oil collector support plate is fixed. 3 position; by rotating the second adjusting screw 11 to control the vertical movement of the upper clamping sleeve 12 and the lower clamping sleeve 13 (the internal threads of the two are opposite, and the movement in the opposite direction is realized), and the upper and lower clamping sleeves 13 are disengaged Adjust the horizontal angle of the supporting plate 6 of the clamping assembly when rotating the shaft 9, and fix the position of the supporting plate 6 of the clamping assembly when the upper and lower clamping sleeves 13 clamp the rotating shaft 9; After completing the docking with the device 4, insert the oil supply guide rod 19 into the oil inl...

Embodiment 2

[0064] Such as Figure 6 As shown, the difference between Embodiment 2 and Embodiment 1 is that: the inner end of the oil supply guide rod 19 is connected with a second clamping positioning block 30, and the two sides of the second clamping positioning block 30 are respectively provided with connecting holes and The slot, the oil supply guide rod 19 is inserted into the connecting hole, and the slot is facing the first clamping positioning block 16 . For the external fuel injector whose oil inlet hole position is different from that of the built-in fuel injector, the second clamping positioning block 30 and the first clamping positioning block 16 are used to complete the clamping.

[0065] The present invention also has the following beneficial effects:

[0066] The invention is a test fixture used for various fuel injectors. For different fuel injectors, the clamping assembly can perform various rotation adjustments to complete the smooth docking of fuel supply parts, fuel i...

Abstract

The invention discloses a test fixture for various oil injectors. The test fixture comprises a base plate, wherein an upright post is arranged on the base plate; an oil collector supporting plate, a horizontal adjusting mechanism and a clamping assembly supporting plate are sequentially arranged on the upright post from bottom to top; a height adjusting mechanism is arranged in the oil collector supporting plate and is used for adjusting the height of the oil collector supporting plate; the horizontal adjusting mechanism is used for adjusting the horizontal angle of a clamping assembly supporting plate; and a clamping assembly is arranged on the clamping assembly supporting plate and is used for tightly clamping and fixing the built-in oil injectors. The test fixture for various oil injectors solves the technical problems that the structure of a conventional fixture is simple; when the angle or the center line of the oil injectors changes, the installation and clamping cannot be realized by the same fixture; and a corresponding fixture needs to be replaced, so that the production cost is increased.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a test fixture for various fuel injectors. Background technique [0002] The electronically controlled fuel injector is the most critical and complex component in the common rail system, and it is mainly composed of a fuel injector and a fuel injector body. The test work of the fuel injector is usually done by the fuel collector. During the test, the fuel injector and the fuel collector need to be connected by a jig. [0003] The traditional fixture structure is single. When the angle or center line of the injector changes, the same fixture cannot be clamped, and the corresponding fixture needs to be replaced, which increases the production cost. [0004] In view of the single structure of the traditional fixture in the related art, when the angle or centerline of the injector changes, the same fixture cannot be clamped, and the corresponding fixture needs to be replaced, whi...
