There is a fine-tuning oblong hole, and fine-tuning screws are arranged in the fine-tuning oblong hole. The positioning part is a positioning plate, and the clamping part is a clamping plate. A track cavity is formed between the positioning plate and the clamping plate in the guide rail baffle and the side plate of the guide rail. , There is a slider in the track cavity, and an adjustment hole is set on the positioning plate of one of the guide rail baffles, and a clearance adjustment screw is provided in the adjustment hole, and the clearance adjustment screw passes through the adjustment hole and is connected with the threaded hole on the side plate of the guide rail. It has the advantages of convenient and quick adjustment of the gap between the moving auxiliary guide rail and the slider.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a movable pair experimental simulation device with a simple structure, convenient and quick adjustment of the gap between the movable pair guide rail and the slider, and the adjustable gap between the slider and the guide rail. Background technique [0002] As we all know, with the continuous development of precision mechanical engineering, the mechanical system is moving towards the goal of high speed, high precision, and high efficiency. Motion pair gaps are unavoidable. The existence of the gap will increase the collision force of the kinematic pair gap, aggravate the damage and wear of the mechanism, and cause the output response of the mechanism to vibrate violently, resulting in serious noise and vibration, resulting in a decrease in the movement accuracy and stability of the mechanism, or even failure, especially The impact on high-speed institutions is e...

Problems solved by technology

However, in the previous experimental research on the dynamic performance of mechanisms with clearance, most of them focused on the experimental research on the influence of the clearance of the rotating pair on the dynamic performance of the mechanism. Considering the moving pair clearance as an ideal kinematic pair, it is impossible to simulate the moving pair clearance, so the experimental research on the dynamic performance of the crank-slider mechanism considering the moving pair clearance has not yet been carried out.

[0004] In addition, the slider crank mechanism is widely used in the field of mechanical engineering, and is one of the basic components of most actual machines. During the working process of the slider crank mechanism, wear and tear will occur between the slider and the guide rail, resulting in an increase in the gap between the moving pair and the mechanism The change of the output response leads to the reduction of system accuracy and performance degradation, and the existing moving pair experimental device cannot adjust the moving pair gap, so it is impossible to simulate the fact that the moving pair gap increases due to wear and tear during the working process of the slider crank mechanism.
