Description

Technical Field

[0001] The invention relates to the technical field of press-fitting mechanisms, and in particular to a press-fitting mechanism with a positioning function. Background Art

[0002] When the end of the shaft workpiece is pressed, the shaft body is required to maintain the coaxial deviation with the press-fitted part and the pressure head during the positioning and clamping process to ensure the normal progress of the press-fitting operation. Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. During the press-fitting process of the bearing, it is usually necessary to use a bearing press-fitting positioning mechanism to center and press the bearing and the sleeve. The quality of the plug-in shaft installation directly affects the accuracy of the installation object and whether the installation object is suitable for other mechanical structures. Traditional plug-in shaft installation mostly adopts manual operation, and uses knocking, pressing down and other methods to achieve the installation of the plug-in shaft. However, since the manual method cannot control how much the two ends of the plug-in shaft extend out of the installation object after the plug-in shaft is inserted into the installation object, the accuracy in this regard is difficult to control, and it is easy to be damaged due to excessive force during the installation of the plug-in shaft. In addition, manual operation cannot guarantee the force direction of the plug-in shaft, which may cause deviation in the installation position, affecting the use effect. Manual operation is slow and inefficient, which is not conducive to mass production.

[0003] The existing press-fitting mechanism with positioning function uses an adjustable clamp to fix shaft workpieces of different specifications. However, in this method, the clamp is in a sliding state during use, and then the shaft workpiece can be pressed. The clamp needs to operate in a sliding state, but this method may cause debris to stick to the sliding rod supporting the clamp when used for a long time, thereby affecting the sliding of the clamp.
