Description

Technical Field

[0001] This invention relates to a calibration device for the angular displacement of a capacitive sensor, belonging to the field of precision testing, data calibration, and calibration. Background Technology

[0002] With the development of precision measurement technology, higher requirements have been placed on the testing of some components and the data calibration and calibration of sensors, requiring the achievement of higher accuracy.

[0003] To enable rapid calibration and testing of certain test or sensor components, a three-axis rotatable symmetrical testing device was designed for calibrating the angular displacement of capacitive sensors, based on the characteristics of the tests and calibration requirements. Furthermore, this structure requires fewer adjustable parameters, better ensures the test position, reduces reliance on manual adjustments, offers high adjustment accuracy, and improves work efficiency.

[0004] In view of the above-mentioned testing needs and functional structure design, a set of devices has been designed to assist in testing and to calibrate and recalibrate some sensors with rotation functions, thereby improving the efficiency of related testing, calibration and recalibration. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of inaccurate testing and calibration caused by the inability to achieve precise positioning in existing methods, and to propose a calibration device for the angular displacement of a capacitive sensor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The capacitive sensor angular displacement calibration device includes: a micrometer head, a device frame, a frame support rod, a nut, a linear bearing, a slider around the X-axis, a connecting column, a slider around the Z-axis, a support frame for rotating slide rails around the Z-axis, a bearing bracket, a crank handle, a linear slide rail, a bidirectional lead screw, a rotating slide rail around the Z-axis, a rotating slide rail around the X-axis, a lower capacitor plate, an upper capacitor plate, a custom connecting column, a bearing, and a crank handle connection mechanism.

[0008] The frame support rod is installed on the device frame and fastened with nuts; the linear slide rail is installed in the positioning groove on the device frame base and fastened with hexagon socket screws; the two bearing supports are installed on the two end faces of the device frame base along the longest direction and locked to the base with nuts; the bearings are installed in the circular holes of the bearing supports and locked with hexagon socket set screws; the bidirectional lead screw is installed in the bearing inner holes of the two bearing supports and the end face of the lead screw keeps the lead screw from axial movement; the rocker arm is installed at the slotted part of one end of the bidirectional lead screw.

[0009] The threaded holes of the Z-axis rotating slide rail support frame are respectively installed on both sides of the bidirectional lead screw and arranged symmetrically. The two support slots of the Z-axis rotating slide rail support frame are installed on the linear slide rail. The upper end of the Z-axis rotating slide rail support frame is installed together with the Z-axis rotating slide rail. The X-axis rotating slide rail is connected to the Z-axis slider via a connecting column. The Y-axis rotatable function is connected to the X-axis rotatable module via a customized connecting column, and all three axes can rotate. The above process completes the construction and connection of the three-axis rotatable module, and symmetrical reciprocating motion is achieved through the threaded features of the support base. The linear slide rail ensures the smoothness of the motion and the reliability of the connection. The changes in the angles of the different rotating axes can be adjusted with high precision using multiple circular gratings.

[0010] The lower capacitor plate is reliably connected to a custom-designed connecting post, which clamps the lower capacitor plate and is rotatable within the X-axis slider. The upper capacitor plate is connected to a linear bearing and can move smoothly up and down. The micrometer head is connected to the upper plate of the device frame via its own threads and locked with a nut. An internal threaded hole is made on the lower end face of the micrometer head, which is connected to the upper capacitor plate with a screw. The micro-motion characteristic of the micrometer head drives the upper capacitor plate to move.

[0011] Compared with other technologies, this invention provides a capacitive sensor angular displacement calibration device, which has the following advantages:

[0012] 1. The device achieves rapid positioning by utilizing a symmetrical structure and a bidirectional threaded rod, and achieves smooth reciprocating linear motion by combining double linear slide rails;
