Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a general positioning tool for electric brushes of conductive plastic potentiometer type angular displacement sensors, which comprises a bottom plate 1, a compression spring 4, a sliding support 5, a pressure head 8, a screw rod 3 arranged on the bottom plate 1 and a positioning bottom plate 11; the compression spring 4 is sleeved on the screw rod 3 and presses the bottom plate 1, and the sliding support 5 is slidably mounted on the screw rod 3 and presses the compression spring 4; the upper end of the screw rod 3 is provided with a compression nut 6, and the compression nut 6 is pressed on the sliding support 5; the part that sliding support 5 was passed to 8 upper ends of pressure head is equipped with lock nut 7, pressure head 8 is located positioning bottom plate 11 directly over, positioning bottom plate 11 is last to be equipped with the shop bolt 9 that is used for fixed product, the vertical backstop screw 2 that is equipped with on the bottom plate 1.
As shown in fig. 1, in the present embodiment, the positioning base plate 11 is fixed on the base plate 1 by a mounting pin 10.
For clearer explanation the utility model discloses the structure, following detail the utility model discloses well brush location frock's theory of operation:
(1) rotating the sliding support 5 to a position where the positioning bottom plate 11 is not shielded, clamping the product 12 to a mechanical zero position shown in the figure, and installing 2 positioning pins 9 to lock the product 12 to the mechanical zero position;
(2) coating an adhesive on an electric brush component of a product 12, mounting the electric brush component on an angular displacement sensor product, rotating a sliding bracket 5 to a position shown in figure 1, and rotating a compression nut 6 to press a pressure head 8 down to the electric brush component compressing the product 12;
(3) applying +/-1V (DC) voltage to the fixed end of the product 12, testing output voltages at two ends, rotating the assembled electric brush component by using tweezers to enable the output voltages at two ends to be 0V, namely an electric zero position, and enabling the mechanical zero position and the electric zero position of the product of the conductive plastic potentiometer type angular displacement sensor to coincide;
(4) placing the electric brush general positioning tool and the fixed product into a proper environment for adhesive curing, and taking down the product 12 after the adhesive is cured, namely the product 12 realizes the coincidence of the mechanical zero position and the electrical zero position;
(5) when products with different signal specifications are replaced, the pressure head 8, the positioning pin 9 and the positioning bottom plate 11 only need to be redesigned and manufactured.
The utility model discloses a positioning error analysis:
(1) in order to ensure that the pressure head 8 can smoothly press the electric brush component of the product 12, a preferential matching system based on national recommendation is adopted at a plurality of matching positions of the tool, and in order to ensure that all parts of the tool are easy to replace and the sliding fit clearance is small, an H7/g6 base hole system is selected for matching, the matching system can realize the sliding fit with small clearance, and the precision positioning is realized while the free movement and the sliding are realized.
