Problems solved by technology
[0002] In the field of pressure assembly, it is usually necessary to press a certain part into the workpiece through pressure. Often the workpiece and the press-fitting equipment are positioned with two positioning pins on the bottom surface. When the part is pressed in, the workpiece is in a state of unilateral force. At this time, the two positioning pins are subjected to the shear force generated by the force on one side of the workpiece. If the force on one side is too large, the positioning pin will be in danger of breaking, which will cause the workpiece to shift, resulting in the phenomenon that the press-fit parts are not installed properly. At present, in order to solve the unbalanced force caused by the force on one side of the workpiece, a supporting mechanism is usually installed on the other side of the force-bearing surface, and an equal force is applied to the side of the workpiece so that the workpiece reaches a force-balanced state.
In the past, the support structure usually used hydraulic cylinders to support the workpiece, so as to achieve force balance on both sides of the workpiece. When selecting a hydraulic cylinder, it is necessary to select a hydraulic cylinder with the same pressure according to the pressure on the side of the workpiece. At the same time, it is necessary to consider the hydraulic pressure when selecting a hydraulic cylinder. The volume of the cylinder, the installation method and other factors, therefore, the scope of application of this self-defense support mechanism is very limited, and the versatility is not strong

The invention discloses a two-stroke self-defense supporting mechanism used for press fitting. The two-stroke self-defense supporting mechanism used for press fitting comprises a supporting body and asupporting shaft; a first inclined board moving in the horizontal direction and a second inclined board moving in the vertical direction are arranged inside the supporting body; the first inclined board is provided with a first inclined face and a second inclined face; the second inclined board is provided with a third inclined face and a fourth inclined face; when the second inclined board movesdownwards in the vertical direction, the third inclined faces slides on the first inclined face till being disengaged from the first inclined face; the process that the second inclined board drives the first inclined board to rapidly move in the horizontal direction is the speeding stroke; the fourth inclined face slides on the second inclined face after making contact with the second inclined face; and the process that the second inclined board drives the first inclined board to move in the horizontal direction is the working stroke. As the first inclined board the second inclined board areeach provided with the two inclined faces, speeding and working of the supporting shaft can be achieved through sliding between the corresponding inclined faces, self locking is achieved through the contact between the inclined faces, workpieces achieve stress balanced accordingly, the structure is simple, and universality is high.
