The support 100 is connected to a table 700 for connection with a rigid wheel. The outer edge of the test piece 200 has a first test surface 210, the test piece 200 being adapted for connection to a compliant wheel. The first driving device 800 is fixed to the supporting member 100, a rotating shaft of the first driving device 800 is connected to the wave generator, and the first driving device 800 is used for driving the wave generator to rotate. The bracket 900 is attached to the table 700. The dial indicator 300 is connected to the bracket 900, the measuring head 310 of the dial indicator 300 can be abutted against the first testing surface 210, and the dial indicator 300 can move along the first setting direction relative to the supporting member 100.
Specifically, the dial indicator 300 is connected to the worktable 700, the measuring head 310 of the dial indicator 300 can abut against the first testing surface 210 of the testing piece 200, and the dial indicator 300 can move along a first set direction relative to the first testing surface 210, so that the straightness of the first testing surface 210 along the first set direction can be measured through the dial indicator 300. In the working process, firstly, the straightness of the initial position of the first testing surface 210 is read out through the dial indicator 300, after the straightness is tested, the dial indicator 300 is separated from the first testing surface 210, the rotating space of the testing piece 200 is made free, and then the rotating shaft of the first driving device 800 is controlled to rotate forward at an angle alpha (alpha can be any angle such as 30 degrees, 60 degrees and 90 degrees) so as to drive the wave generator to rotate, thereby driving the testing piece 200 to rotate. After the forward rotation is completed, the rotation shaft of the first driving device 800 is controlled to rotate in the reverse direction by the angle α, and the dial indicator 300 is abutted against the first testing surface 210 again to measure the straightness of the first testing surface 210. When the idle stroke of the harmonic reducer 1000 is detected according to the difference between the straightness of the initial position and the straightness of the final position of the first testing surface 210, it can be understood that the idle stroke detection device of the embodiment has a simple structure, is convenient to operate, and has a low cost. In addition, the first driving device 800 drives the wave generator to rotate, so that the efficiency is higher compared with manual rotation, the forward and reverse rotation angle consistency is higher, and the detection idle stroke detection precision is improved.
Assuming that the dimension of the first testing surface 210 along the first setting direction is L, the idle stroke conversion formula is as follows:
θ 1= (180/pi) ((2 a/L) × 3600 (clockwise), θ 2= (180/pi) ((2 a/L) × 3600 (counterclockwise), and the backlash = θ 1+ θ 2. Where a is the reading of the dial gauge 300.
Referring to fig. 1, in some embodiments, the idle stroke detection apparatus further includes a translation mechanism 400, the translation mechanism 400 is connected to the worktable 700, the first setting direction is a horizontal direction, the translation mechanism 400 includes a second driving device 410, the second driving device 410 is connected to the supporting member 100, and the second driving device 410 can drive the supporting member 100 to move horizontally so as to drive the testing member 200 to move.
Specifically, the first setting direction is along the horizontal direction, and during idle stroke detection, the first driving device is used for driving the test piece 200, so that the first test surface 210 is adjusted to be in the horizontal state, the first driving device 800 is used for driving the test piece 200 to rotate forward and backward, and the straightness of the first test surface 210 along the horizontal direction is measured, it can be understood that, relative to other directions, the horizontal state of the first test surface is more easily measured, for example, the level of the first test surface 210 can be conveniently and quickly adjusted through a level meter, and repeated measurement of the first test surface 210 is not needed through the dial indicator 300, so that the adjustment time is saved.
In addition, it should be noted that the reason why the first testing surface 210 is adjusted to the horizontal position is that the measurement value of the dial indicator 300 has a certain range. Due to the idle stroke factor of the harmonic reducer 1000, after the test piece 200 rotates forward and backward, the front and back positions of the first test surface 210 change, so as to avoid detection failure caused by the fact that the front and back position deviation of the first test surface 210 is large and exceeds the measurement range of the dial indicator 300. In the present embodiment, the first testing surface 210 is adjusted to a horizontal position, i.e. the same direction as the first setting direction, so that the initial value of the dial indicator 300 is 0.
Referring to fig. 2, in some embodiments, the translation mechanism 400 further includes a first screw module 420, the first screw module 420 includes a first ball screw 421 and a first sliding table 422, the first ball screw 421 extends along the horizontal direction, the first driving device 800 is connected to the first ball screw 421, and the supporting member 100 is connected to the first sliding table 422.

The screw rod drive has the advantages of high transmission efficiency and high idle stroke detection speed, and the screw rod drive also has the advantages of high transmission precision and stable motion and improves the detection precision of the straightness of the first test surface 210, thereby improving the idle stroke detection precision of the harmonic reducer 1000.

Based on this, in order to improve the service life of the supporting member 100, the present embodiment connects the reinforcing portion 130 between the mounting portion 120 and the side of the mounting portion 120 away from the mounting surface 121. The reinforcement portion 130 is disposed on the side of the connection portion 110 away from the mounting surface 121, so as to make room for mounting the harmonic reducer 1000 and the test piece 200, thereby reducing the volume and weight of the support 100 and the amount of material used for manufacturing the support 100, and saving cost.
