Description
Technical field
The utility model relates to automobile steering systems to demarcate tooling technical field, more particularly, to a kind of electric power steering
System sensor Calibrating experimental bench.
Background technique
Existing electric boosting steering system torque sensor needs to carry out electrical null position calibration, is first to sensor at present
Electric signal calibration is carried out, then torsion sensor is welded and fixed in installation axle, in welding, needs to find electrical letter manually
Number zero-bit, then welded, may result in when welding that position alignment is incorrect, cause electric signal to demarcate unqualified.Such as
What guarantees that torsion sensor guarantees the accuracy of electrical null position after mounting, while improving the efficiency of calibration, is that current production is anxious
A problem to be solved.
Utility model content
The purpose of the utility model is to provide a kind of electric boosting steering system transducer calibration testing stands, solve existing torsion
It is welded after the calibration of square sensor electric signal, error rate is big, the low problem of qualification rate.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of electric boosting steering system sensor
Calibrating experimental bench, including workbench are arranged shaft fixing block on the table, are additionally provided with column on the workbench, stand
Column is movably fixed with sliding seat moving up and down, and shaft clamping device is fixedly installed in sliding seat；On the workbench also
It is provided with the caliberating device connecting with torque sensor electric signal, drive shaft is connected with below the shaft fixing block
The rotary electric machine that fixing seat rotates together.
Further, it is provided with the sliding rail of two vertical directions on the column, is additionally provided with driving motor and driving motor
The screw rod of drive, the nut with screw rod cooperation is provided in the sliding seat, and driving motor drives sliding seat to move up and down.
The utility model has the beneficial effects that the utility model is installed the torsion bar being welded by one workbench of design
Onto workbench, rotates by rotary electric machine and torque signal is transported in caliberating device and demarcate, which mentions significantly
The high accuracy of torque calibration, and it is easy to operate, it is convenient.
Below with reference to drawings and examples, the utility model is described in detail.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the main view of the utility model.
Fig. 3 is the structural schematic diagram of torsion bar in the utility model.
Specific embodiment
Embodiment, as shown in Figures 1 to 3, a kind of electric boosting steering system transducer calibration testing stand, for demarcating as schemed
Torsion bar shown in 3, including upper semiaxis 12, lower semiaxis 13 and the torque sensor 14 being assemblied between upper and lower axle 12 and lower semiaxis 13,
The stator of torque sensor 14 is connect with upper semiaxis 12, and rotor is connect with lower semiaxis 13.The testing stand includes workbench 1, setting
Shaft fixing block 2 on workbench 1 is additionally provided with column 3 on the workbench 1, and column 3, which is movably fixed with, to be moved up and down
Sliding seat 4, be fixedly installed with shaft clamping device 5 in sliding seat 4.The specific structure of sliding seat 4 are as follows: set on the column 3
It is equipped with the sliding rail 8 of two vertical directions, is additionally provided with the screw rod 10 that driving motor 9 and driving motor 9 drive, in the sliding seat 4
Be provided with screw rod 10 cooperate nut, driving motor 9 drive sliding seat 4 move up and down be additionally provided on the workbench 1 with
The caliberating device 6 of torque sensor electric signal connection, the lower section of the shaft fixing block 2 is connected with drive shaft fixing block
2 rotary electric machines 7 rotated together are additionally provided with the controller 11 that control rotary electric machine 7 works.
When calibration, first semiaxis 12 under the torsion bar being welded is fixedly mounted in shaft fixing block 2, then starting driving electricity
Machine 9 moves downward, and the shaft clamping device 5 in sliding seat 4 is made to be fixedly clamped the upper semiaxis 13 of torsion bar.Then controller 11 is controlled
Rotary electric machine 7 processed rotates, and torque sensor 14 receives the torque value for rotating each point and passes to caliberating device 6, caliberating device 6
According to the torque value of acquisition and calculating analysis is carried out, obtains the electric signal calibration value of the torque sensor 14, to be entrucking
Improve accurate feedback data.
The utility model is exemplarily described in conjunction with attached drawing above.Obviously, the utility model implements not
It is limited by aforesaid way.As long as the various unsubstantialities that the method concept and technical solution that use the utility model carry out
Improvement；Or it is not improved, the above-mentioned conception and technical scheme of the utility model are directly applied into other occasions, at this
Within the protection scope of utility model.
