Description

Technical Field

[0001] This utility model relates to the technical field of actuator suspension and holding devices, specifically to a linear actuator suspension and holding device. Background Technology

[0002] Linear actuators are typically equipped with two spherical hinges, one at the cylinder end and one at the piston end. The spherical hinge mainly consists of three parts: a hinge seat, a rod end spherical bearing, and a hinge shaft. The hinge seat and the rod end spherical bearing can rotate and oscillate around the spherical bearing.

[0003] The linear actuator is suspended at its upper end by a ball joint to the load-bearing mechanism, and at its lower end by a piston rod to apply load to the stressed component. A typical load-bearing mechanism, such as a reaction frame, consists of a load-bearing beam and columns at both ends of the beam, with the columns vertically fixed to a horizontally positioned load-bearing platform. The actuator is suspended below the load-bearing beam; ideally, the actuator's structural center axis coincides with the direction of the load acting on the stressed component and passes perpendicularly through the load-bearing platform surface. Otherwise, the reaction frame and actuator will experience a counterforce from a bias, affecting the accuracy of the actuator's movement and potentially leading to instability in both the actuator and the reaction frame.

[0004] Therefore, it is of great importance to design a suspension and holding device for linear actuators to solve the above-mentioned defects. Utility Model Content

[0023] The vertical beam is perpendicularly connected to the base plate;

[0024] The diagonal brace is connected at one end to the base plate and at the other end to the vertical beam.

[0025] As a preferred embodiment of this utility model, the fixing frame and the load-bearing crossbeam are connected by a second fastener.

[0026] In a preferred embodiment of this utility model, the connecting beam and the fixing frame are connected by a first fastener.

[0027] As a preferred embodiment of this utility model, it also includes:

[0028] A connecting beam is connected to the fixed frame;

An adjusting sleeve is installed inside the fixing frame and the connecting beam, with its hexagonal structure close to the actuator. An arc-shaped plate assembly is installed inside the adjusting sleeve, with its arc surface fitting against the actuator. Rotating the four adjusting sleeves causes the arc-shaped plate assembly to extend or retract, pushing the actuator to a set angle. Tightening the first fastener on the adjusting sleeve and the arc-shaped plate assembly fixes them in place, thus allowing adjustment and maintenance of the actuator angle suspended below the supporting beam. This ensures that the structural central axis coincides with the direction of the load acting on the load-bearing component and passes perpendicularly through the supporting platform surface.
