Description

Technical Field

[0001] The present invention relates to the field of electric technology, and in particular to a gear-driven electric cylinder trunnion support device. Background Art

[0002] The trunnion support device is a crucial component of the electric cylinder system. It primarily consists of a trunnion, a bearing seat, and a mounting bracket. The trunnion, a key component, is connected to the cylinder body at one end and to the mounting bracket via a bearing seat at the other. The bearing seat provides support and rotation for the trunnion, ensuring its flexible rotation. During operation, the trunnion support device plays a crucial role. It withstands the lateral forces and torques generated by the electric cylinder during operation, distributing these forces to the mounting bracket to ensure stable operation. For example, when the electric cylinder is pushing a large object, the trunnion support device effectively prevents the cylinder from deflecting due to excessive lateral forces. Furthermore, it enables the electric cylinder to oscillate within a certain angle range, enhancing its flexibility. For example, in industrial production, when the electric cylinder needs to change its working direction or adjust its angle, the trunnion support device can achieve this by controlling the trunnion's swing. The design and installation of this device must fully consider the working environment and actual needs of the electric cylinder to ensure its reliability and stability, providing a strong guarantee for the efficient operation of the electric cylinder.

[0003] The existing electric cylinder ear shaft support device has some shortcomings during installation and use. First, its rotation accuracy is limited. When the electric cylinder drives the load to rotate, it is difficult to achieve high-precision rotation positioning due to the fitting clearance between the ear shaft and the bearing seat and the influence of machining accuracy, resulting in a large rotation angle deviation. Secondly, during the rotation process, the friction between the ear shaft and the bearing seat is large, which not only consumes energy, but may also cause increased wear and shorten the service life of the device. Moreover, the structural design of the electric cylinder ear shaft support device is relatively complex. When performing rotational deflection, a large amount of space is required, which is a great limitation for some work scenarios with limited space. In addition, during the rotation process, due to the influence of the external environment, such as temperature, humidity, etc., the rotation performance of the ear shaft will be affected to a certain extent, resulting in unstable rotation speed, thereby affecting the working efficiency of the electric cylinder. These shortcomings limit the application scope and working effect of the electric cylinder ear shaft support device to a certain extent, and bring certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a gear-driven electric cylinder ear shaft support device. Summary of the Invention

[0017] 1. In the present invention, the coordinated action of the first servo motor and the second servo motor realizes the precise positioning and clamping of the electric cylinder. The first servo motor drives the first bevel gear to rotate, so that the base frame rotates, providing a basis for the rough positioning of the electric cylinder. The second servo motor drives the clamping base to rotate through the universal joint to realize the fine adjustment of the electric cylinder. The cooperation of the first cylindrical gear and the first rack enables the base frame to drive the deflection frame to slide in the first sliding groove, further accurately positioning the electric cylinder.

[0018] 2. In the present invention, the first bevel gear is driven to rotate by the third servo motor, which drives a series of components to move, thereby realizing the swing adjustment of the lower surface of the deflection seat. This process can accurately control the swing amplitude and angle, so that the ear shaft can adapt to various working requirements under different working conditions. The first buffer spring and the second buffer spring provide buffering force, effectively reducing vibration and impact, and protecting the structure and components of the device from damage. The swing adjustment function improves the stability and reliability of the equipment, ensuring that the electric cylinder ear shaft maintains a good posture during operation, thereby improving work efficiency and product quality.

[0019] 3. In the present invention, after the electric telescopic rod is started, it pushes the second bevel gear to engage with the first bevel gear, and the first bevel gear is driven to rotate by the third servo motor to realize the rotation of the electric telescopic rod, thereby driving a series of components to operate. This process causes the reciprocating deflection column to rotate, and the second cam block is driven to rotate through the synchronous wheel, so that the sliding rod slides at the axis of the reciprocating deflection column, driving the placement block and the maintenance frame to move, and the fourth servo motor drives the second cylindrical gear to engage with the second rack, and performs operations such as cleaning brushing or applying lubricating oil on the side of the maintenance frame close to the center of the circle.
