Abstract
The utility model belongs to a power assisted steering oil pump blade straightness verifying attachment that hangs down, including base (6), positioning seat (5) are equipped with on base (6), end face centre is equipped with plane A and facade B mutually perpendicular on positioning seat (5), its characterized in that is with one (3) one fixed support frame (2) on the bolt on the right -hand member plane of base (6), be equipped with in the middle of the upper portion of support frame (2) open slot (9), lower extreme at open slot (9) is equipped with the round hole, one electronic sensor (1) is equipped with in the round hole, and it is fixed with electronic sensor (1) with bolt two (8). The utility model discloses a to the blade straightness detection precision height that hangs down, repeatability is little, need not frequently rectify and examine an error, and is fast, efficient, stops the erroneous judgement.
Description
Technical field
This utility model belongs to pump blade inspection equipment, particularly to the power-assisted steering oil pump blade verticality detecting device of the power-assisted of a kind of motor turning.
Background technology
Power steering system is to utilize the power of electromotor to carry out driving automobile power-assisted steering oil pump to help driver to carry out the device of handling maneuver.Power-assisted steering oil pump is the power source of automobile steering system, and hydraulic energy as medium by hydraulic oil, is converted to mechanical energy, thus alleviates the intensity of driver's steering, improve the navigability of vehicle simultaneously by it.
The perpendicularity of steering pump Leaf, directly affects service behaviour and the service life of oil pump.Such as blade out of plumb, the most then let out in causing, affect the volumetric efficiency of oil pump.Heavy then scratch oil distribution casing, makes reduce the service life of pump, the most then makes oil pump be destroyed.In the past, about the problem of blade perpendicularity, generally we use knife-edge square and tool microscope to measure perpendicularity, but the former can not record the amount of deflection, and the latter needs to adjust, calculate, and precision is low can not obtain measurement result accurately, can not meet production requirement.In order to improve the product quality of oil pump, do it yourself to have developed blade verticality detecting device, this device uses mechanical type amesdial to measure, indicating value or hysterisis error is easily produced using a period of time gear-driven abrasion and drive gap, reduce certainty of measurement, and frequently correcting value Watch Error makes detection efficiency reduce；Measurement result relies on observes indicator position, easily produces erroneous judgement.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, it is provided that a kind of employing electronic sensor, high to blade perpendicularity testing accuracy, repeatable accuracy is little, need not frequently correct cubing error, will not produce the power-assisted steering oil pump blade verticality detecting device of erroneous judgement.
This utility model solves technical problem and be the technical scheme is that a kind of power-assisted steering oil pump blade verticality detecting device, including base 6, equipped with positioning seat 5 on base 6, it is provided with plane A at center, positioning seat 5 upper surface and facade B is mutually perpendicular to, it is characterized in that fixing a bracing frame 2 with bolt 1 in the right-hand member plane of base 6, open slot 9 it is provided with in the middle of the top of bracing frame 2, it is provided with circular hole in the lower end of open slot 9, equipped with an electronic sensor 1 in circular hole, and with bolt 28, electronic sensor 1 is fixed.
The beneficial effects of the utility model are: this utility model is high to blade perpendicularity testing accuracy, and repeatable accuracy is little, need not frequently correct cubing error, and speed is fast, and efficiency is high, stop erroneous judgement.

Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the main body figure of power-assisted steering oil pump blade verticality detecting device.
In figure: 1-electronic sensor；2-bracing frame；3-bolt one；4-limited block；5-positioning seat；6-base；7-blade to be detected；8-bolt two；9-open slot；10-wire.
Detailed description of the invention
Embodiment, referring to the drawings, a kind of power-assisted steering oil pump blade verticality detecting device, including base 6, equipped with positioning seat 5 on base 6, it is provided with plane A at center, positioning seat 5 upper surface and facade B is mutually perpendicular to, it is characterized in that fixing a bracing frame 2 with bolt 1 in the right-hand member plane of base 6, in the middle of the top of bracing frame 2, be provided with open slot 9, be provided with circular hole in the lower end of open slot 9, equipped with an electronic sensor 1 in circular hole, and with bolt 28, electronic sensor 1 is fixed.
Supporting and be connected with wire 10 equipped with limited block 4. electronic sensor 1 one end between seat 2 and positioning seat 5, the other end contacts with blade 7 to be detected.
The detection method of this detection device is: first coupled together with IBR B200 sensing amount instrument by wire 10, with hands, perpendicularity standard gauge block is pressed on plane A and the facade B of positioning seat 5, calibration IBR B200 inductance measuring meter zero, again the arc surface of blade 7 to be detected is repeated downwards action above, test, directly read the reading on IBR B200 sensing amount instrument；Complete inspection.
Using this device inspection blade linear error less than 0.3%, repeatable accuracy is less than 0.1 μm, and the inspection of blade perpendicularity reaches the high accuracy of 0.1 μm, need not frequently correcting value Watch Error, beneficially blade be grouped, divides credit rating.Directly display measurement numerical value by the LED screen of IBR B200 sensing amount instrument, show qualified defective signal with red yellowish green trichromatism, the most substantially, stop erroneous judgement.
