Problems solved by technology

Not only does this increase the number of elements that can be subject to wear in the actuation assembly, but it can also ultimately lead to a lack of precision in the alignment of the movement of the sensor to the shaft, resulting in insufficient detection accuracy and thus the need for constant maintenance in order to ensure timely sensor Proper operation for good measurement accuracy

Embodiment Construction

[0045] In the following description, elements having the same functional structure are denoted by the same reference numerals in order to explain the drawings. Also, for the sake of clarity, some reference numerals may not be shown in all drawings.

[0046] Expressions such as "vertical" and "horizontal", "upper" and "lower" (in the absence of further indications) should refer to installation (or operating) conditions, and to terms normally used in the current language, where "vertical " means a direction substantially parallel to the direction of the gravitational vector force "g" and "horizontal" means a direction perpendicular to that direction.

[0047] refer to figure 1 , which shows a first preferred embodiment of the rotary linear actuation assembly of the present invention, generally designated by reference numeral 10 .

[0048] The rotary linear actuator assembly 10 includes a housing 25 in which two actuators 11, 12 are housed, wherein a first actuator or linear ac...

Abstract

The invention relates to a rotary linear actuation assembly (10, 110) comprising a housing (25, 125) containing within it an actuation shaft ( A) Coaxially arranged output shaft (14, 113); at least two actuators, wherein a first actuator (11, 111) is adapted to apply an translational movement of (A), and a second actuator (12, 112) adapted to impart on said output shaft (14, 113) a rotational movement about the drive axis (A); and at least one position sensor (30, 130) adapted to detect the instantaneous position of the output shaft (14, 113) within said housing (25, 125). Said assembly is characterized in that said at least one position sensor (30, 130) is mounted fixed relative to rotation about said actuation axis (A) and fixed relative to translation along said actuation axis (A) , and facing at least a part of said output shaft (14, 113).

Description

technical field [0001] The invention relates to an improved rotary-linear actuation assembly, in particular to a rotary-linear actuation assembly with high operation precision and high reliability. Background technique [0002] Rotary-linear actuators are currently used in several industrial applications that require the same output shaft of the actuator to be able to provide rotary motion as well as linear motion simultaneously or sequentially in an independent manner. [0003] In order to accurately and reliably control the movement of the output shaft of such an actuator, it is necessary to be able to monitor the instantaneous angular position and the instantaneous longitudinal position of the shaft in real time. [0004] Therefore, in prior art actuation assemblies, multiple sensors are currently used, each dedicated to detecting a specific spatial coordinate of said output shaft, in order to obtain the instant position of the shaft, and to set the action according to th...
