[0002] Currently, the tilt measurement devices on the market use photoelectric parallel autocollimators and optical multifaceted prisms to achieve 360° rotation and measure 12-21 angle points.

[0003] This type of optical device can meet high-precision measurement requirements, but the equipment cost is relatively high. In addition, the optical device requires manual installation and calibration of optical deviation positions during use.

[0004] Therefore, a more accurate and convenient low-cost method for measuring tilt linearity accuracy remains to be solved. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A tilt sensor accuracy measurement device includes a horizontal base plate mounting plate, a motor mounting plate vertically fixed to the base plate mounting plate, a motion controller, a motor driver, and a host computer. A servo motor with a built-in encoder is fixed on the motor firmware mounting plate, and a sensor mounting bracket is fixed on the horizontal output shaft of the servo motor; the tilt sensor to be detected is fixed on the sensor mounting bracket. The motion controller and motor driver are respectively fixed to the base plate mounting plate; The host computer is electrically connected to the servo motor through the motion controller and the motor driver in sequence to realize the host computer's control of the rotation of the output shaft of the servo motor. The host computer collects angle data from the tilt sensor.

[0007] Furthermore, it also includes a protective shell fixed to the base plate mounting plate, the protective shell having an opening for taking out and putting in the tilt sensor; The front side of the protective shell is transparent and is perpendicular to the motor mounting plate.

[0008] Furthermore, the left side of the protective shell is close to the tilt sensor, and the left side is detachably connected to the protective shell, allowing the tilt sensor to be removed when the left side is detached.

[0009] Furthermore, a pair of handles are fixed to the left and right sides of the protective shell.

[0010] Furthermore, it also includes a 220V power switch and a power switch socket for power supply, and the front side of the protective shell is set as a front-mounted PVC transparent plate; The 220V power switch and power switch socket are fixed on the front PVC transparent plate; The tilt sensor accuracy measurement device is directly powered by a 220V power supply.

[0011] Furthermore, the sensor mounting bracket includes a horizontal plate and a vertical plate fixed perpendicular to each other. The vertical plate is fixed to the output shaft and arranged vertically, and the tilt sensor is fixed to the horizontal plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This tilt sensor accuracy measurement device features servo motor rotation angle adjustment and real-time monitoring of angle deviation data, suitable for measuring the angle accuracy of tilt sensor equipment. Utilizing the high precision of the servo motor's rotation, the host computer sets the rotation angle and speed of the servo motor's output shaft to monitor the tilt sensor's movement.
