Description

Technical Field

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

[0002] The trunnion support device of an electric cylinder is an important component in the electric cylinder system. It mainly consists of a trunnion, a bearing housing, a fixing frame, etc. As a key component, one end of the trunnion is connected to the cylinder body of the electric cylinder, and the other end is connected to the fixing frame through the bearing housing. The bearing housing provides the conditions for supporting and rotating the trunnion to ensure that the trunnion can rotate flexibly. During operation, the trunnion support device of the electric cylinder plays an important role. On the one hand, it can bear the lateral force and torque generated during the operation of the electric cylinder and disperse these forces to the fixing frame to ensure the stable operation of the electric cylinder. For example, when the electric cylinder pushes a large object, the trunnion support device can effectively prevent the electric cylinder from deviating due to excessive lateral force. On the other hand, it can also make the electric cylinder swing within a certain angle range to enhance the flexibility of the electric cylinder. For example, in industrial production, when the electric cylinder needs to change the working direction or make an angle adjustment, the trunnion support device can achieve this function by controlling the swing of the trunnion. The design and installation of this device need to 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 trunnion support devices of electric cylinders have some disadvantages when installed and used. First of all, their rotation accuracy is limited. When the electric cylinder drives the load to rotate, due to the influence of the clearance between the trunnion and the bearing housing and the machining accuracy of the machine, it is difficult to achieve high-precision rotation positioning, resulting in a large deviation in the rotation angle. Secondly, during the rotation process, the friction force between the trunnion and the bearing housing is relatively large, which not only consumes energy but also may cause increased wear and shorten the service life of the device. Moreover, the structural design of the trunnion support device of the electric cylinder is relatively complex, and a large amount of space is required for rotation and deflection, which is a great limitation for some working 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 trunnion will be affected to a certain extent, resulting in unstable rotation speed, thus affecting the working efficiency of the electric cylinder. These disadvantages limit the application range and working effect of the trunnion support device of the electric cylinder to a certain extent, bringing certain adverse effects to the using process. To solve the deficiencies of the existing technology, we propose a trunnion support device for a gear-driven electric cylinder. Summary of the Invention

[0017] 1. In the present invention, accurate positioning and clamping of the electric cylinder are achieved through the coordinated action of the first servo motor and the second servo motor. 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 achieve 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.

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 ear shaft of the electric cylinder 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, the second bevel gear is pushed 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 the side of the maintenance frame close to the center of the circle is cleaned with a brush or lubricated with lubricating oil.
