Problems solved by technology

However, although it is automatic docking, the inner hexagonal connection between the shafts cannot avoid the problem of jamming due to surface contact, and it is difficult to dismantle. The dismantling process will affect the adjustment of the six-axis adjustment frame; therefore, it cannot be used as a tool, and at the same time. When the shafts are connected, the problems of eccentricity, deflection, and axial deviation between the shafts cannot be solved

Abstract

The invention relates to the technical field of motor connecting devices for projection display devices, in particular to an elastic connecting device. The elastic connecting device comprises a motor device, elastic couplers, a six-shaft adjusting frame, adjusting shafts and limit shaft bushings. The adjusting shafts are arranged in the six-shaft adjusting frame, and the limit shaft bushings are sleeved outside the adjusting shafts and fixedly connected with the same. Each elastic coupler is connected with a motor output shaft of the motor device and comprises a connector, an elastic structure, an elastic shaft and a limit plate, and the elastic structures, the elastic shafts and the limit plates are arranged in the connectors. The limit plates are fixed on the connectors, one ends of the elastic shafts are arranged in the connectors, and the other ends of the elastic shafts penetrate through the limit plates. Each limit shaft bushing is provided with a clamp structure, the elastic shafts are clamped into the clamp structure, the elastic couplers are connected with the adjusting shafts, and the output shaft of the motor drives the adjusting shafts to rotate. The elastic shafts and the limit shaft bushings are matched, so that connection among the shafts cannot be stuck, and wire contact is realized simultaneously. The elastic couplers are free of affection of eccentricity and angle deflection, and eccentricity and angle deflection of connection among the shafts are solved.

Description

technical field [0001] The present invention relates to the technical field of motor connection devices used in projection display devices, and more particularly, to an elastic connection device. Background technique [0002] The image signal of the existing display screen is generally adjusted through a six-axis adjustment frame. For example, Chinese patent CN102338167A discloses "a motor device for a projection display device". There is a transfer device on it, the transfer device includes a slider mechanism and a screw mechanism; the slider mechanism includes a fixed guide and a guide sleeve that can move axially relative to the fixed guide to solve the connection between the two, projection The six axes of the six-axis adjustment frame of the display device realize automatic electric adjustment. However, although it is automatic docking, the inner hexagonal connection between the shafts cannot avoid the problem of jamming due to surface contact, and it is difficult to...
