the above is a common structure of the existing press-fitting equipment, when the workpiece is required to be press-fitted, the workpiece is firstly placed on the placing table 1, then the cylinder 41 is controlled to work through the control mechanism, the cylinder 41 drives the upper die 42 to move towards the direction of the placing table 1 during working, and in the process of contacting with the workpiece and continuously moving, the pressure is applied to the workpiece to be press-fitted, so that the workpiece is deformed, and the press-fitting requirement is met.

In the long-term working process of the press-fitting equipment, the upper die 42 can generate tiny displacement due to frequent movement and long-term contact with a workpiece, so that the upper die 42 is not parallel to the placing table 1, if the upper die 42 is not timely regulated, the press-fitting effect is not ideal, therefore, parallelism test is required to be carried out on the press-fitting equipment, the fact that the pressed workpiece cannot meet the production requirement due to the fact that the parallelism is not up to standard is prevented, and the press-fitting equipment is provided with a parallelism detection mechanism in a matched mode, and the parallelism detection mechanism is suitable for being placed between the upper die 42 and the placing table 1 so as to carry out the parallelism test on the press-fitting equipment;
