Measuring mechanism

Abstract

The invention provides a novel measuring mechanism comprising a pedestal and a base arranged above the pedestal. The base is successively connected with a joint 1, a measuring arm 1, a joint 2, a measuring arm 2, a joint 3 and a measuring head. A pulley is arranged above one end, connected to the joint 1, of the measuring arm 1. A connection block is arranged above the other end, connected to the joint 2, of the measuring arm 2. The measuring mechanism further comprises a steel belt which has one end connected to the connection block and the other end connected to a counter weight after passing by the pulley. According to the novel measuring mechanism of the invention, manual operation is easy, the stability of the mechanism is enhanced, and the measuring accuracy is guaranteed.

Description

technical field [0001] The invention relates to a measuring mechanism. Background technique [0002] Testing agencies such as figure 1 As shown, it is often used in the field of mechatronics. It is a mobile and portable manual measurement system. During the actual measurement, the weight of the measurement arm and joints is completely borne by human hands, which will easily make the operator tired and affect the measurement accuracy. Although it can be reduced The components of the mechanical structure and the selection of light materials can reduce the weight of the measuring mechanism, but it cannot be reduced infinitely, that is, this problem cannot be fundamentally solved. In addition, when the measurement is not performed, the two parts of the measuring mechanism The measuring arm, measuring head and joints will naturally sag under the action of their own weight, so that most of the weight of the entire measuring system is biased to one side. In order to prevent the en...

[0002] Testing agencies such as figure 1 As shown, it is often used in the field of mechatronics. It is a mobile and portable manual measurement system. During the actual measurement, the weight of the measurement arm and joints is completely borne by human hands, which will easily make the operator tired and affect the measurement accuracy. Although it can be reduced The components of the mechanical structure and the selection of light materials can reduce the weight of the measuring mechanism, but it cannot be reduced infinitely, that is, this problem cannot be fundamentally solved. In addition, when the measurement is not performed, the two parts of the measuring mechanism The measuring arm, measuring head and joints will naturally sag under the action of their own weight, so that most of the weight of the entire measuring system is biased to one side. In order to prevent the entire measuring mechanism from turning over, the base needs to be very heavy and fixed very firmly. Not only greatly increases the weight of the entire measuring mechanism, but also makes it difficult to fix the measuring machine
