Embodiment Construction

[0010] The specific embodiments of the patent of the present invention are described in detail below in conjunction with technical solutions and accompanying drawings.

[0011] Such as figure 1 As shown, the measuring head 1 is installed on the transmission lever 3 for measuring the small displacement in the X direction. The transmission lever is fixed on the support 4 by two spring sheets (cross spring sheets 2 ) placed across each other, and the sensor 5 is located on the right side of the transmission lever. During the measurement process, the workpiece rotates around the fixed axis in the direction of the arrow. When the surface contacted by the probe 1 has a shape error, the probe 1 will be displaced in the X direction, causing the transfer lever to rotate with the intersection of the cross spring pieces as the fulcrum, resulting in the following Effect: The left and right translation distance of probe 1 is linearly related to the up and down movement distance measured b...

Abstract

The invention discloses a device for micro-displacement direction conversion, which belongs to the technical field of precision mechanical measurement and is used for the conversion of micro-displacement so as to be able to measure accurately. It is characterized in that the device is mainly composed of a measuring head, a cross spring leaf, a transmission lever and a sensor. The measuring head is installed on the transmission lever and is used to measure the small displacement in the X direction. The transmission lever is fixed on the support through the cross spring leaf, and the sensor is located on the right side of the transmission lever. When the measuring head is displaced in the X direction, the transmission lever can convert the displacement into the Y direction displacement with the intersection point of the cross spring as the fulcrum, and then realize the conversion of the displacement direction and realize accurate measurement. The invention has the beneficial effects of high sensitivity, small measurement force, no gap, simple operation and accurate displacement transmission for a small amount of rotation.

Description

technical field [0001] The invention belongs to the technical field of precision mechanical measurement, and relates to a device for changing the direction of micro-displacement, which can change the direction of displacement and facilitate accurate measurement. Background technique [0002] In the field of engineering, due to reasons such as inconvenient location or narrow space, some small displacements need to be converted in direction before they can be measured. The conversion process of the small displacement direction must strictly guarantee the additional error in the conversion process. The current conversion displacement direction is generally realized by a lever device, and the fulcrum of the lever adopts the method of hole shaft matching. Due to the fit clearance of the hole shaft, additional errors are added in the process of displacement transmission, which ultimately affects the measurement accuracy of small displacements. Therefore, it is very necessary to ...
