The rotation angle monitoring of the full-circle rotary part is to install the circular magnetic grid on the outer ring of the full-circle rotary part, and use a magnetic grid sensor to monitor the circular magnetic grid. For the rotary part with a V-shaped notch, due to the The V-shaped gap cannot be installed with a full-circle circular magnetic grid, and the magnetic grid sensor cannot detect the rotation angle at the V-shaped gap. Therefore, other methods must be used to monitor the rotation angle of the rotary part with a V-shaped gap. There is no relevant report on the signal acquisition method of the rotation angle of the notch rotary part

Embodiment Construction
[0027] The invention relates to a signal acquisition method for the rotation angle of a rotary part with a V-shaped notch. In the signal collection method, two symmetrically configured magnetic grid sensors with complementary functions are used to measure the magnetic grid scale attached to the rotary part with a V-shaped notch. Carry out signal acquisition, thereby solving the rotation angle monitoring of the rotary part with V-shaped notch, the signal acquisition is accurate and reliable, and has a great assisting effect on the computer control of the rotation angle of the rotary part with V-shaped notch, especially for extra-large and precise rotation angles As far as the swivel with V-shaped notch is concerned, its significance is even more profound.
[0028] The present invention can be explained in more detail through the following examples. The present invention is not limited to the following examples. The purpose of disclosing the present invention is to protect all ch...

A signal acquisition method of the rotation angle of a rotating member with a V-shaped notch includes: the V-shaped notch area where the V-shaped notch area of the rotating member (5) is arranged is defined as a blind area (3), a magnetic grid scale (2) is stuck on the periphery of the rotating member with the V-shaped notch and is provided with scale marks, a main positioner (4) and an auxiliary positioner (8) are symmetrically arranged on both sides of the magnetic grid scale, the main positioner is used for fixing a main magnetic grid sensor (1), the auxiliary positioner is used for fixing an auxiliary magnetic grid sensor (7), and the main magnetic grid senor and the auxiliary magnetic grid sensor are configured in a 180-degree symmetry mode. The complementary magnetic grid sensors can subject the magnetic grid scale on the rotating member with the V-shaped notch to signal acquisition, so that the monitoring of the rotation angle of the rotating member with the V-shaped notch can be achieved, and the signal acquisition is accurate and reliable. The signal acquisition method of the rotation angle of the rotating member with the V-shaped notch has a great assisting effect on controlling the rotation angle of the rotating member with the V-shaped notch through a computer and is particularly significant to super-huge type and rotation-angle precision-required rotating members with V-shaped notches.
Description
technical field [0001] The invention belongs to the technical field of rotation angle monitoring, in particular to a signal acquisition method for the rotation angle of a rotary member with a V-shaped notch. Background technique [0002] With the rapid development of the machinery industry, the requirements for the accuracy of the rotation angle of the rotary parts with V-shaped notches are getting higher and higher. The rotation angle monitoring of the full-circle rotary part is to install the circular magnetic grid on the outer ring of the full-circle rotary part, and use a magnetic grid sensor to monitor the circular magnetic grid. For the rotary part with a V-shaped notch, due to the The V-shaped gap cannot be installed with a full-circle circular magnetic grid, and the magnetic grid sensor cannot detect the rotation angle at the V-shaped gap. Therefore, other methods must be used to monitor the rotation angle of the rotary part with a V-shaped gap. There is no relevant...
