Technical field
The present invention relates to a kind of velocity sensor automatic adjustment mechanism for gap.
Background technique
When testing, it is determining that velocity sensor incudes the gap adjustment between end face and sender gear to velocity sensor
The principal element whether sensor performance meets the requirements, it is usually 0mm that velocity sensor, which incudes end face and the gap of sender gear,
~200mm need to be adjusted to specified gap (0.3mm~2mm), and the method for adjustment in existing gap is: velocity sensor is mounted on
In test adaptor mounting bracket, while using the side of artificial moving speed sensor mounting bracket and the phase position of testing gears
Formula carries out gap adjustment, and the clearance gauge that the detection in gap generallys use contact is verified.After gap, which is adjusted to specified, to be required,
Mounting bracket is locked again, reaches the gap between product and sender gear.
There are following disadvantages with the mode detected for existing gap adjustment:
1) gap alignment error is larger, when mounting bracket adjusts, needs to be verified with clearance gauge in real time, the tight of clearance gauge will cause mistake with loose
Difference；After clearance gauge confirmation, when locking bracket, thread pitch will also result in scale error；The two error usually be greater than ±
0.1mm。
2) operational consistency is poor, since alignment error is big, causes consistency to guarantee difficult, highly dependent upon the skill of operating staff
Can, but nonetheless, there are still the gaps between same employee's multi-pass operation also cannot keep consistent phenomenon, influences product
Performance indicator and test consistency.
3) production efficiency is low, adjusts backing positions in real time and is simultaneously verified with clearance gauge, then adjust and locking mode, the operating time is logical
Often need more than 1 minute.
4) it is tested velocity sensor induction end face and is also easy to produce scratch, examine slotted mode with clearance gauge, clearance gauge necessarily contacts
Tested velocity sensor incudes end face, there is induction end face scratch risk, influences product appearance, serious to lead to customer complaint.

Specific embodiment
With reference to the accompanying drawing, the present invention is further described for embodiment.
As shown in Figure 1, velocity sensor gap adjust automatically and detection device, including stage body 1, linear motion component 2, survey
Try bracket 4, velocity sensor to be measured 5, test mounting plate 6, laser range sensor 7, testing gears 8, limiting device 9, control
Device (is not drawn into) in figure.
As shown in Fig. 2, above-mentioned linear motion component 2 includes servo motor 23, linear guide, linear guide includes high-precision
Screw rod 22 and mounting plate 3.
Above-mentioned test bracket 4 is mounted on the mounting plate 3 of linear motion component 2.
Above-mentioned test mounting plate 6 is mounted on test bracket 4.
Above-mentioned velocity sensor to be measured 5 is mounted on test mounting plate 6.
Above-mentioned testing gears 8 are fixed on stage body 1.
Above-mentioned linear motion component 2 drives high-precision screw rod 22 to reach the accurate fixed of mounting plate 21 by servo motor 23
Position, to drive the position adjustment of the test bracket 4 connecting with linear module 2, test mounting plate 6 and tested sensor 5, adjustment
The gap of itself and testing gears 8.
Gap Adjustment precision depends primarily on the control precision of linear motion component precision 2.In the present embodiment, above-mentioned straight line
Moving parts 2 select the high-precision screw rod of 0.05 mm of positioning accuracy, 0.02 mm of back clearance, ± 0.005 mm of repetitive positioning accuracy
22, select high-precision servo motor 23,23 preferred site mode of servo motor, single pulse adjusts gap width at 0.03 μm,
Gap adjustment deviation precision can be controlled in 0.05 mm.
Above-mentioned laser range sensor 7 is arranged on two sides of the movement routine of velocity sensor 5 to be measured, and is fixed on platform
On body 1.When electro-optical distance measurement sensor 7 just senses tested 5 end face of sensor, electro-optical distance measurement sensor 7 is sent a signal to
Controller, controller reset 2 position of linear motion component (the mobile distance of linear motion component 2), adjust base as gap
Quasi- zero point can eliminate velocity sensor 5 to be measured because of error caused by interindividual variation in this way.
After 2 position of linear motion component is reset, further according to given gap width X, the tune that needs move forward can be obtained
Whole value Y, 8 tip diameter/2 of Y=H-X- testing gears, wherein H is the spacing of laser range sensor 7 and testing gears 8, is
Fixed value is determined by this mechanical location, it is desirable that gap width X can be shown on PC, such as: it is required that test gap X be 1.5mm,
The spacing of laser range sensor 7 and testing gears 8 is 160mm, and 8 tip diameter of testing gears is 304, practical adjusted value Y
For 160-1.5-152=6.5mm.
