Description
Technical Field
The utility model relates to an angle displacement sensor preparation frock especially relates to a high accuracy angle displacement sensor preparation is with adjusting frock.
Background
An angular displacement sensor (potentiometer) is an important angular position feedback component and is mainly used for angular displacement measurement of equipment such as a servo motor and the like and for feeding back the absolute position of a rotating component such as a rotating shaft of the servo motor. With the development of science and technology, angular displacement sensors are widely applied to the technical fields of industry, ships, aviation, aerospace and the like which have high technical indexes and various severe test requirements on high precision and long service life.
The basic structure of the angular displacement sensor comprises a shell, a rotating shaft, a resistor body (a conductive plastic resistor body), an electric brush, a collector ring and an insulating sleeve, wherein the rotating shaft penetrates through a corresponding through hole in the shell and is connected with the through hole through a bearing, the resistor body is arranged in the shell, the rotating shaft penetrates through a central through hole of the resistor body, the insulating sleeve is sleeved on the rotating shaft, the collector ring is arranged on the insulating sleeve, and the electric brush is arranged on the collector ring and is in contact with a resistance band of the resistor body. When the device works, an external device drives the rotating shaft to rotate, the rotating shaft drives the insulating sleeve, the collector ring and the electric brush to synchronously rotate, the electric brush slides on the resistance belt of the resistor body in a contact manner to generate a changed electric signal, and the external processor calculates and obtains the rotation angle information of the rotating shaft according to the change quantity of the electric signal to realize the angular displacement detection function.
With the wide application of the angular displacement sensor in various precision devices, the requirement on the detection precision of the angular displacement sensor is higher and higher, and besides the detection precision of the angular displacement sensor has important relations with the precision of the resistor body (such as uniformity, resistivity consistency and the like of a conductive plastic layer), the contact reliability of the brush and the resistor body and the like, whether the zero setting position of the angular displacement sensor is accurate is also one of very important influencing factors, namely whether the brush is positioned at the middle position of the resistor belt when the sensor is positioned at the zero position, and if the zero setting position of the angular displacement sensor is not accurate, the detection precision is inevitably influenced. To more clearly illustrate this problem, reference is made to the following description taken in conjunction with the accompanying drawings:
as shown in fig. 1, a resistance band 6 having an arc shape is provided on a first resistor 1 of the sensor, a first power supply positive input terminal 2 and a first power supply negative input terminal 7 are provided at both ends of the resistance band 6, respectively, and a positive electrode and a negative electrode of an external power supply are connected to the first power supply positive input terminal 2 and the first power supply negative input terminal 7 through a lead 8, respectively. Fig. 1 also shows a conductive strip 3 arranged on the first resistor 1, the middle of the conductive strip 3 is provided with a signal output terminal 4, the conductive strip 3 is not necessarily structured, and the conductive strip 1 is a commonly used electric signal transmission structure for transmitting the electric signal collected by the first brush 11 in fig. 2 to the first signal output terminal 4 through the second brush 9; in addition, the center through hole 5 of the first resistor 1 is used for the shaft to pass through.
In application, with reference to fig. 1 and 2, the first brush 11 and the second brush 9 are respectively mounted on the first slip ring 10 and are electrically connected to each other, the first brush 11 is in contact with the resistive strip 6, the second brush 9 is in contact with the conductive strip 3, and the theoretical zero setting position of the sensor is that the first brush 11 is located at the middle position of the resistive strip 6, and correspondingly, the second brush 9 is located at the middle position of the conductive strip 3, as shown in fig. 3. However, in general, it is difficult to achieve high-precision zeroing, that is, the first brush 11 and the resistive band 6 are offset from each other in the middle, as shown in fig. 2, in the production process, the traditional zeroing method mainly depends on the feeling and experience of the operator, so that it is difficult to eliminate the offset, and the zeroing operation is more difficult after the sensor is shipped because the whole sensor is packaged.
In addition, a dual-redundancy angular displacement sensor is also a commonly used angular displacement sensor, and the detection accuracy can be improved by using two circuit components (one circuit component comprises a resistor body, an insulating sleeve, a collector ring and one or two brushes), or the dual-redundancy angular displacement sensor can still work normally when one circuit component fails. In addition to the problem of insufficient zeroing precision, the dual-redundancy angular displacement sensor also has the problem of low synchronization precision between two circuit components, which also causes the detection precision of the whole sensor to be reduced, so that the angular displacement sensor is difficult to be applied to the application occasions with extremely high requirements on the detection precision.
In summary, at present, there is no dedicated adjusting tool for zero adjustment of the angular displacement sensor, and even no adjusting tool for synchronization adjustment of the angular displacement sensor, and in the conventional adjusting process, only a simple clamp or other structure is used for assisting the adjusting process, so that it is difficult to realize an accurate and efficient adjusting function.
