Embodiment Construction
[0022] The present invention will be further elaborated below by specific embodiment:
[0023] The invention relates to an incremental linear rotation two-degree-of-freedom position detection device, comprising a housing 1, an integrated cup-shaped code disc 2 arranged in the housing, a photoelectric sensor, and a linear rotation bearing;
[0024] The shell 1 is a cup-shaped structure with an open top, and a fixed shaft 6 is arranged at the center of the inner bottom of the shell;
[0025] The integrated cup-shaped code disc 2 is a cup-shaped structure made of acrylic material, the top is provided with a connecting shaft 7 connected to an external detection motor, and the bottom is a disc with a central hole, and the fixed shaft 6 passes through the central opening. The hole extends to the inner top of the integrated cup-shaped code disc; the disc is engraved with m (m=200, 500, 1024, 2048...) pieces of black and white lines distributed along the circumference to form a rotary...
