The urea pump bracket is located on the middle layer of the testing tool and used for placing a urea pump for testing. The urea tank bracket is located below the urea pump bracket, and two urea tank supports are located on the two sides of the center of the urea tank bracket. The testing tool for the urea liquid level sensor is provided with the multiple layers of placing brackets and can be suitable for perpendicularly placing urea tanks of kinds of sizes on the ground, universal wheels with locks are installed at the bottom of the testing tool, moving is convenient, placing is flexible, and the testing equipment and the urea tanks can be conveniently placed in the testing process.
Description
Technical field
The present invention relates to automatically controlled parts detection field, particularly a kind of test fixture of urea liquid level sensor.
Background technology
The economic performance that the operating accuracy of automatically controlled parts quality and reliability are run for car load and emission behavior impact great.Along with tightening up of national motor vehicle emission policy, automatically controlled aftertreatment parts before supporting car load through strict inspection be necessary.
Wherein, urea liquid level sensor must coordinate urea tank to test together, and urea tank needs vertical ground to place.Due to present main flow urea tank out-of-shape, ground cannot be stood on voluntarily.Testing scheme in the past does a square glove framework, and urea tank is placed on it, then installs liquid level sensor, and connect ECU or other signals collecting control instruments, measuring equipment is placed on short table.This kind of scheme easily causes test process wiring to meet with fortuitous event because testing apparatus and measurand are not placed in unified position getting loose, and mobile very inconvenient, can not suitable for multiple sizes urea tank is supporting flexibly sensor test.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of test fixture of simple and reasonable urea liquid level sensor, the test fixture of this urea liquid level sensor has Multi-layer article storing bracket, sizes urea tank vertical ground can be applicable to place, and locking universal wheel is equipped with in bottom, be convenient to mobile, place flexibly, the Placement Problems in test process of testing apparatus and urea tank can be solved easily.
For achieving the above object, the invention provides the test fixture of urea liquid level sensor, comprising: extension leaf rack, it is positioned at the upper strata of this test fixture, for placing testing apparatus; Urea pump bracket, it is positioned at the middle level of this test fixture, for placing test urea pump; And urea tank bracket, it is positioned at the below of described urea pump bracket, and the central both sides of this urea tank bracket have two urea tank supports.
Preferably, in technique scheme, the side Zhou Yousi root post of test fixture supports, and the bottom of described four root posts is respectively arranged with universal wheel, and this universal wheel has brake lock.
Preferably, in technique scheme, test fixture is rectangular parallelepiped framed structure.
Preferably, in technique scheme, the table ground clearance 1.1m of extension leaf rack.
Preferably, in technique scheme, the transverse width of urea tank bracket is 800mm, and the spacing of described two supports is 200mm.
Preferably, in technique scheme, the height distance of urea tank bracket and urea pump bracket is greater than 700mm.
Compared with prior art, the present invention has following beneficial effect: the test fixture of this urea liquid level sensor has Multi-layer article storing bracket, sizes urea tank vertical ground can be applicable to place, and locking universal wheel is equipped with in bottom, be convenient to mobile, place flexibly, the Placement Problems in test process of testing apparatus and urea tank can be solved easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the test fixture of urea liquid level sensor of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, be three story frame structures according to the test fixture of the urea liquid level sensor of the specific embodiment of the invention, specifically comprise: the extension leaf rack 1 being positioned at upper strata, the urea pump bracket 2 being positioned at middle level and be positioned at the urea tank bracket 3 of bottom, wherein, extension leaf rack 1 is for placing the article such as testing apparatus and power supply, and the exploitation also can carrying out urea pump for technician when desk is debugged; Urea pump bracket is for placing test urea pump; Urea tank bracket can be applicable to sizes urea tank vertical ground and place, and locking universal wheel is equipped with in the bottom of the test fixture of this urea liquid level sensor, be convenient to mobile, place flexibly, the Placement Problems in test process of testing apparatus and urea tank can be solved easily.
Specifically, this test fixture is rectangular parallelepiped framed structure, and side Zhou Yousi root post 4 supports, and extension leaf rack 1, urea pump bracket 2 and urea tank bracket 3 lay respectively at the upper, middle and lower layer of four root posts 4.This test fixture divides upper, middle and lower three layer article-retaining shelf, makes full use of vertical space and tested object and testing apparatus is placed in above a frock, reduces test and taken up space.The bottom of four root posts 4 is respectively arranged with universal wheel 5, and this universal wheel 5 has brake lock, test fixture is convenient to mobile, makes test no longer by space constraint.And can lock by brake lock the stability that universal wheel 5 keeps this test fixture in urea liquid level sensor test process after moving into place.
Extension leaf rack 1, for placing the article such as testing apparatus and power supply, makes the article such as testing apparatus and power supply to be placed on layer article-retaining shelf easily.In addition, the exploitation that extension leaf rack 1 can carry out urea pump for technician when desk is debugged, table ground clearance about the 1.1m of extension leaf rack 1, meet ergonomics, personnel when can reduce long-time use are tired, and can need outwards to shift out partial distance or dismounting according to test.
Urea tank bracket 3 is positioned at the bottom of four root posts 4, the below of urea pump bracket 2, is greater than 700mm with the height distance of urea pump bracket 2.The transverse width of urea tank bracket 3 is about 800mm, central authorities both sides have two supports 6, for from supported on both sides urea tank, make it place perpendicular to ground, and the wiring after making urea tank load onto liquid level sensor pass in the testing apparatus that is connected to and is positioned at extension leaf rack 1 from the grid of upper strata urea pump bracket 2.The spacing of two supports 6 is about 200mm, and maximum ratio has taken into account the application of main flow urea tank leakage fluid dram and lateral dimension.
