Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model discloses a detection apparatus for motor positioning accuracy, test stick 3 and measured motor 4 including frock support 1, encoder 2, standard. The tested motor 4 is fixedly arranged on the tool support 1, and the calibrated standard testing rod 3 is arranged at the output end of the tested motor 4 and can rotate along with the tested motor 4. The encoder 2 is coaxially arranged outside the standard inspection rod 3 and is arranged on the tool support 1 to detect the rotation angle of the standard inspection rod 3. The rotation of the tested motor 4 is controlled by a control system, and the control system is also used for receiving the detection signal fed back by the encoder 2 and simultaneously processing and calculating the detection signal.
The utility model discloses during the use, can be fixed in on the fixed workstation with frock support 1, will be surveyed motor 4 and install the back, the axiality of stick 3 is tested with the standard to the encoder 2 of having adjusted, can detect. The encoder 2 detects the position angle of the standard testing rod 3 to indirectly obtain each positioning precision of the tested motor 4. If the positioning accuracy of the measured motor 4 is detected, firstly, the measured motor 4 is controlled to drive the standard check rod 3 to rotate for a certain angle, the detection value a of the encoder 2 is extracted as a reference value, then the measured motor 4 continues to rotate for a fixed angle B in the same direction, the detection value C of the encoder 2 is extracted, the difference value between the detection value C and the reference value a is calculated to be the actual rotation angle D (D = C-a) of the measured motor, the deviation value between the actual rotation angle D and the fixed angle B is calculated to be the positioning accuracy of the measured motor 4, and after the detection method is repeated for multiple times, the maximum value of each deviation value is taken to be the final positioning accuracy of the measured motor 4.
And continuing the method, rotating the tested motor 4 by a fixed angle B and then reversely rotating by the same angle B, extracting a detection value E of the encoder 2 at the moment, calculating the difference value between the reference value A and the detection value E to be used as the reverse clearance of the tested motor 4, and averaging for multiple times to obtain the final reverse clearance of the tested motor 4.
And driving the tested motor 4 to rotate for 360 degrees by taking the detection value A as a reference value, extracting the detection value F of the encoder at the moment, and calculating the difference between the detection value F and the reference value A to obtain the repeated positioning precision of the tested motor 4.
The detection method is not unique, and can be adjusted timely according to the detection condition.
Although the present invention has been described in detail, the present invention is not limited thereto, and those skilled in the art can make various modifications according to the principle of the present invention. Therefore, modifications made in accordance with the principles of the present invention should be understood to fall within the scope of the present invention.
