Left and right prefastening parallel connection structure six-dimensional force sensor

Abstract

The present invention discloses a left and right pre-compact type six dimensional force sensor with a parallel structure. The characteristics are: the left pre-compact platform (6) is a half-open type case component; the right pre-compact platform (2) which has a structure identical to that of the left pre-compact is symmetrical with the left pre-compact platform (6); the six detecting components (3) are divided into two groups that are distributed on the two sides of the stand board of the force measuring platform; the detecting component (3) and the middle power measuring platform (1) are sealed in a pre-compact form through connection bolts (4) and nuts (5) by the left and right pre-compact platform (6,2); the six detecting components (3) are connected to the force measuring platform (1) and the left and right pre-compact platform (6,2) through ball and socket steeple head type spherical pair. The structure of the sensor and the measuring principle are simple; the slot of each spherical pair is eliminated and the friction moment of each spherical pair is reduced and the nonlinearity and lag error are reduced; the device has a low cost and is easy to produce and to form precise and a series of products. The device can be used in the any occasions that need six dimensional forces detecting such as robots, aerospaceplanes, etc.

Description

technical field [0001] The invention relates to the field of design and manufacture of a force sensor, in particular to a six-dimensional force sensor with a left and right pretensioned parallel structure, which can be used to test three-dimensional force components and moment components in a space. Background technique [0002] With the rapid development of science and technology, the requirements for sensors in the fields of measurement, control and information technology are getting higher and higher. Sensor technology has become one of the cores of high-tech and plays a very important role in industrial production, national defense construction and science and technology. important role. The force sensor is the most basic type of sensor. Because the traditional unidirectional force sensor cannot measure multi-dimensional force and moment comprehensively, the multi-dimensional force sensor has been fully developed and applied in many fields. The six-dimensional force and...
