With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
As shown in figure 1, a kind of velocity sensor performance index detection device of the invention, can be detected multigroup different simultaneously
Velocity sensor, it is specifically included：Main spindle box 2, base 8, main shaft 3, gear 4 and sensor mounting unit, the inside of main spindle box 2 is
Empty and bottom-open, base 8 is connected to the unlimited place of the bottom of main spindle box 2, a cavity is surrounded together with main spindle box 2；Main shaft 3 passes through
Bearing is connected horizontally on main spindle box 2, and the end of main shaft 3 is connected with motor 1, and motor 1 is arranged on main spindle box 2；Gear 4 is at least
Provided with two, all gears 4 are both connected on main shaft 3, and sensor mounting unit also includes multiple, and is correspondingly arranged with gear 4.
Sensor mounting unit includes：Sensor holder 6, guide rod 7, screwed pipe 9 and handle 10, sensor holder 6 are arranged on main spindle box 2
Top, for installing sensor 5 to be measured；Such as Fig. 2, the top of main spindle box 2 is provided with hole, and one end of sensor 5 to be measured passes through the hole
Penetrate in main spindle box 2, just the flank of tooth to gear 4；The two ends of each sensing seat have been fixedly connected with guide rod 7, and guide rod 7 is vertical
Through main spindle box 2 and base 8, and it is slidably connected respectively with main spindle box 2 and base 8；The two ends of guide rod 7 are equipped with nut, lead
It is located at the lower section of base 8 to the nut of the lower end of bar 7, and gap is left between base 8, facilitates the respect thereto 8 of guide rod 7 and main
Axle box 2 moves up and down；On the guide rod 7 of the one end of sensor holder 6, screwed pipe 9 is socketed with, screwed pipe 9 is slided with guide rod 7
Connection, its outside is connected by screw thread with sensor holder 6, and the axis of screw thread is overlapped with the axis of corresponding guide rod 7, screwed pipe 9
Bottom connect with the upper surface of main spindle box 2；The side horizontal of sensor holder 6 is provided with slotted hole, and one end of handle 10 passes through this
Slotted hole passes the outside of sensor holder 6, and the other end of handle 10 is fixedly connected with screwed pipe 9.The height of slotted hole is more than hand
The diameter of handle 10 so that handle 10 can make the motion of above-below direction while horizontally rotating in slotted hole.
It is preferred that, guide rod 7 is linear bearing guide rod, and the junction of itself and main spindle box 2 or base 8 is mounted on directly
Bobbin is held.
It is preferred that, the place connected at the top of main spindle box 2 with screwed pipe 9 sets an annular to test convex around guide rod 7
Platform is, it is necessary to which when detecting the sensor of a certain model, the minimum range of the sensor and gear 4 that are needed during according to detection passes through milling
The height of processing adjustment test boss is cut, until meeting installation requirement；The setting of test boss allows the present invention to a variety of
Different model sensor device is detected that the scope of application is wider.
A kind of operation principle of velocity sensor performance index detection device of the present invention is as follows：
First, according to the diameter of corresponding gear 4, and handle 10 is gone into correct position, adjusts the peace of sensor 5 to be measured
Dress height.Due to the two ends Jun You edges of slotted hole, therefore handle 10 can only be in certain angle range of motion, accordingly, spiral shell
Line pipe 9 can only also be rotated in certain angular range, and the rotation of screwed pipe 9 drives the relative main case of sensor holder 6 to be transported about 2
It is dynamic, drive the opposed gear 4 of sensor 5 to be measured to move up and down；Relative distance between sensor 5 and gear 4 i.e. to be measured is limited
Within the specific limits, after sensor 5 to be measured is installed, its range of movement between gear 4 is to be determined to system, is not in biography to be measured
The situation that sensor 5 is collided with gear 4.Then, start motor 1, allow gear 4 with defined rotational speed, sensor 5 to be measured starts
The kinematic parameter of gear 4 is recorded, the performance of respective sensor can be determined according to the kinematic parameter detected, detection speed is realized
The purpose of sensor.
Adjust between sensor 5 to be measured and gear 4 apart from when, rotate counterclockwise handle 10, screwed pipe 9 is inverse around guide rod 7
Hour hands are rotated, and sensor holder 6 can not be rotated, it is assumed that screw thread is dextrorotation, in the presence of screw thread, and sensor holder 6 drives guide rod 7
Move downward, and then drive sensor 5 to be measured to be moved to the direction close to gear 4；When turn clockwise handle 10 when, sensor
Seat 6 drives sensor 5 to be measured to be moved to the direction away from gear 4, realizes the fine setting of distance between sensor 5 to be measured and gear 4.
That is, when handle 10 be located at slotted hole two ends when, sensor 5 to be measured be located exactly at apart from gear 4 recently and farthest two
Position, as long as controlling two parameters, so that it may avoid sensor 5 to be measured from being collided with gear 4.
As can be seen from the above embodiments, side of the present invention by using multiple gears 4 simultaneously on same main shaft 3
Formula, and each gear 4 correspondence one sensor of configuration is given, realize while the purpose of detection different sensors, improves detection
Efficiency.Distance between sensor and gear 4 is adjusted by handle 10 and screwed pipe 9, due to the two ends Jun You sides of slotted hole
Edge so that handle 10 and screwed pipe 9 can only rotate in certain angular range, therefore the move distance quilt of sensor to be measured 5
Control is within the specific limits；Sensor 5 to be measured will not be collided after installing with gear 4, and detection process will not be damaged because of gear 4
And stop, detection time is short, efficiency high.Guide rod 7 selects linear bearing guide rod, and by linear bearing and main spindle box 2 and
Base 8 is connected, and the two ends of each sensor holder 6 are respectively connected with linear bearing guide rod, therefore sensor to be measured 5 is in motion process
In will not deflect；And the motion of sensor holder 6 is promoted by screw thread, sensor holder 6 under gravity can when
Quarter is close to the screw thread of screwed pipe 9, and the Adjustment precision of the move distance of sensor 5 to be measured is high, the sensor performance index detected
It is more accurate.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and replacement can also be made, these improve and replaced
Also it should be regarded as protection scope of the present invention.
