Semi-automatic shaft alignment mechanism

Abstract

The invention relates to a semi-automatic shaft alignment mechanism. The semi-automatic shaft alignment mechanism comprises a first sample shaft and a second sample shaft. The first sample shaft is arranged on the left side of the second sample shaft. The first sample shaft is provided with a first support. The second sample shaft is provided with a second support. The first support and the secondsupport are movably connected through a ball screw. The left end of the first support is movably connected with an outer gear ring. The outer gear ring is evenly provided with insertion holes. The inner side of the first support and the inner side of the second support are both provided with bevel threaded disks. The inner sides of the bevel threaded disks are provided with wedge-shaped block tracks. The inner sides of the wedge-shaped block tracks are provided with wedge-shaped clamping blocks. The left end of the ball screw is movably connected with a ball screw transmission gear. The firstsupport and the second support are both provided with support connecting pins. The whole mechanism adopts a mechanical semi-automatic manner, the shaft alignment technology is improved, the shaft alignment difficulty is lowered, the alignment precision of two shafts needing to be aligned is improved, and the working efficiency of the shaft alignment process is improved.

Description

technical field [0001] The invention relates to a semi-automatic shaft centering mechanism and belongs to the field of machinery. Background technique [0002] Shaft alignment: The work of connecting more than two shafts so that their axes are on the same line (this line is a natural deflection with a deflection on a vertical plane) is called alignment. Medium; Semi-automatic: Semi-automatic refers to the automatic way of working cycle automatically under the intervention of human beings. Generally, after the working machine automatically completes a working cycle, it will be automatically shut down, and all the mechanisms will return to the starting position, and the worker will unload the machine. Lower the processed parts (or finished products), install new blanks (or raw materials), restart the working machine, and repeat the automatic working cycle again.

[0002] Shaft alignment: The work of connecting more than two shafts so that their axes are on the same line (this line is a natural deflection with a deflection on a vertical plane) is called alignment. Medium; Semi-automatic: Semi-automatic refers to the automatic way of working cycle automatically under the intervention of human beings. Generally, after the working machine automatically completes a working cycle, it will be automatically shut down, and all the mechanisms will return to the starting position, and the worker will unload the machine. Lower the processed parts (or finished products), install new blanks (or raw materials), restart the working machine, and repeat the automatic working cycle again. The rotation center of the two shafts connected by the coupling between the load and the motor should be strictly controlled. Concentric, the coupling must be accurately aligned and centered during installation, otherwise it will cause a lot of stress on the coupling, and will seriously affect the normal work of the shaft, bearings and other parts on the shaft, and even cause Vibration or damage of the whole machine and the foundation, etc. Therefore, the alignment of the load shaft and the motor shaft is one of the most important work links in the installation and maintenance process. The current industrial production is generally carried out by hand. For shaft alignment, by fine-tuning the relative positions of the upper, lower, left and right axes of the two axes, the upper position value a1 and the lower position value a3 are as equal as possible. Similarly, the left position value a2 is also equal to the right position value a4. After that Then fine-tune to make the four position values ​​completely equal, that is, a1=a2=a3=a4, so as to achieve the purpose of radial alignment, but the efficiency of manual alignment is very low, and the installation process is time-consuming and labor-intensive
