Embodiment 1

[0034] Such as figure 1 as shown, figure 1 It is a coaxiality detection device provided by an embodiment of the present invention, which includes a scale frame 10 and a light source emitting device 20 for connecting the motor shaft. The scale frame 10 is provided with a scale (not shown in the figure) A scale and a reflector, the reflector can receive the light source emitted by the light source emitting device 20 and reflect the light source onto the scale.

[0035] The light source emitted by the light source emitting device 20 may be a laser or a common light source, and the present invention is preferably a laser. When the light source emitted by the light source emitting device 20 is an ordinary light source, a convex lens needs to be added so that the ordinary light source is refracted by the convex lens and concentrated at a point on the axis.

[0036] The reflector can be a plane mirror, and the reflector is used to receive the light source emitted by the light sourc...

Embodiment 2

[0055] Such as figure 2 as shown, figure 2 It is a kind of coaxiality detection system provided by an embodiment of the present invention, which includes two motor shafts 30 respectively arranged on the motor pairing platform, the scale frame 10 of the coaxiality detection device as mentioned above, And two described light source emitting devices 20 of the aforementioned coaxiality detection device, the two described light source emitting devices 20 are arranged on the left and right sides of the described scale frame 10 along the vertical direction, and the two described light sources The transmitting device 20 is respectively connected with the two motor shafts 30 .

[0056] The coaxiality detection system provided by the present invention can simultaneously detect the heights of the two motor shafts by arranging light emitting devices on the left and right sides of the scale frame, thereby detecting the heights of the two motors on the carriage, and improving the detecti...

Abstract

The invention discloses a coaxiality detecting device and system. The device comprises a scaleplate rack and a light source emitting device connected with a motor rotating shaft. A scaleplate with scales and a reflection mirror are arranged on the scaleplate rack; and the reflection mirror is able to receive the light source emitted by the light source emitting device and the light source is reflected to the scaleplate. Since the scaleplate with scales and the reflection mirror are arranged on the scaleplate rack, when the device is in use, the light source emitting device is connected with the motor rotating shaft; and the light source emitting device emits a light source and the reflection mirror reflects the light source to the scaleplate after receiving the light source, so that the height of the motor rotating shaft is detected and thus the height of the motor dragging rack is detected, so that the detection precision is improved. The manual measurement of the height of the motorrotating shaft is not needed, so that the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a coaxiality detection device and system. Background technique [0002] The motor-to-drag test refers to the coaxial connection of two motors with appropriate power for load or characteristic tests. When conducting a motor-to-drag test, it is usually necessary to place two motors on two motor-to-drag stands respectively, and the motor shafts of the two motors are connected through a torque sensor. In order to make the two motors on the same axis, it is necessary to check the coaxiality of the motor to the tow stand before the motor to tow test. [0003] At present, the coaxiality detection of the motor-to-trailer mainly uses manual hand-held high-precision rulers to measure the heights of the two motor shafts, and judges whether the motor-to-trailer is on the same axis according to the height of the two motor shafts. [0004] However, the inventor found in the process of re...
