1.Manual riveting fixture:
Manual riveting fixture is a type of equipment used for riveting, and its function is to rivet two or more parts together by applying pressure;
2.Six-link mechanism
The principle of the six-link mechanism is based on the kinematics and mechanics of the connecting rod. In terms of kinematics, the motion of the connecting rod is influenced by its length, how it is connected, and the external driving force. In terms of mechanics, the moment balance and force transmission between the connecting rods are also important factors for the six-link mechanism to achieve motion.
3.Gear connecting rod stepping feeding mechanism:
The gear connecting rod stepping feeding mechanism is a practical mechanical device, which can effectively realize the stepping feeding of materials and provide a reliable conveying method for automated production lines and processing equipment;
Working principle: The gear connecting rod stepping feeding mechanism realizes the stepping feeding of materials through the coordinated movement of gears and connecting rods. Specifically, when the mechanism is running, the rotation of the gear drives the linkage to move, so that the material moves according to a certain step length in the feeding direction. By controlling the rotation speed and direction of the gear, the step length and feeding speed of the material can be controlled;
4.Rocker telescopic mechanism:
Motion characteristics: The motion characteristics of the joystick telescopic mechanism mainly depend on the design and installation of the joystick. Typically, the joystick can be rotated at an angle, and its length can be varied. This mechanism can realize the complex motion trajectory of the object through the rotation and telescopic cooperation of the rocker;
5.Connecting rod downward compression and hold-down mechanism:
The working principle is: when the connecting rod moves downward, the slider slides along the guide rail, transmitting the pressure to other parts in the mechanism, so as to achieve the compressive effect on the mechanism. At the same time, the up and down movement of the connecting rod can also realize the adjustment and control of the mechanism by adjusting other components in the mechanism.
Summary of the design of the connecting rod mechanism:
The connecting rod mechanism is an important part of mechanical transmission, which can realize complex motion trajectories and motion laws, so it is widely used in various machinery and equipment. When designing the connecting rod mechanism, it is necessary to consider the function, motion trajectory, stiffness and strength of the mechanism, and at the same time, it is also necessary to reasonably select and design the structure, material and manufacturing process of the mechanism.
This paper mainly summarizes the design of the connecting rod mechanism from the following aspects:
Determine the function and motion requirements of the mechanism: When designing the connecting rod mechanism, it is first necessary to clarify the function and motion requirements of the mechanism, such as what kind of motion trajectory, motion law and transmission ratio are realized;
Choose the right type of connecting rod: according to the functional and sports requirements, choose the appropriate type of connecting rod, such as four-bar mechanism, five-bar mechanism, etc.;
Kinematic analysis and optimization of the mechanism: According to the selected type of connecting rod mechanism, kinematic analysis and optimization are carried out to determine the relative position and size relationship between each component. Kinematic analysis is the core content of linkage design, and better motion performance and transmission efficiency can be obtained through analysis and optimization.
