Abstract

The press-fit device includes a platform having an upper surface provided with a bearing base; a mounting rack disposed at the upper surface of the platform; a power cylinder mounted at the mounting rack, including a piston chamber, a piston rod and an actuating element intercommunicated with the piston chamber to provide pressure medium, wherein the piston rod is perpendicular to the bearing base; a guiding track disposed at the upper surface of the platform and arranged in parallel to the piston rod; and a press-fit plate disposed at one end of the cylinder rod and slidably sheathed on the guiding track, wherein a surface of the press-fit plate facing the bearing base is provided with a pressure base, and a surface of the pressure base facing the bearing base is provided with a press-fit frame and a pressure sensing device which is configured to detect a press-fit pressure.

First claim

What is claimed is:

1. A press-fit device, comprising:
a platform having an upper surface provided with a bearing base;
a mounting rack disposed at the upper surface of the platform;
a power cylinder mounted at the mounting rack and located above the bearing base, including a piston chamber, a piston rod and an actuating element intercommunicated with the piston chamber to supply the piston chamber with pressure medium and control a pressure in the piston chamber, wherein the piston rod is perpendicular to the bearing base;
a guiding track disposed at the upper surface of the platform and arranged in parallel to the piston rod; and
a press-fit plate disposed at one end of the piston rod and slidably sheathed on the guiding track, wherein a surface of the press-fit plate facing the bearing base is provided with a pressure base corresponding to the bearing base, and a surface of the pressure base facing the bearing base is provided with a press-fit frame and a pressure sensing device, wherein the pressure sensing device is configured to detect a press-fit pressure, and wherein the pressure sensing device comprises a plurality of pressure sensors which are uniformly arranged along the press-fit frame.

2. The press-fit device of claim 1 , further comprising a controller, wherein the controller has an input end communicatively connected to the pressure sensing device and an output end connected to the actuating element so as to control the pressure in the piston chamber.

3. The press-fit device of claim 1 , wherein the bearing base and the pressure base are provided in plural, respectively, and a plurality of bearing bases and a plurality of pressure bases are disposed in one-to-one correspondence.

4. The press-fit device of claim 1 , wherein the pressure sensing device further comprises a plurality of pressure sensitive balls which are uniformly arranged in an array on the surface of the pressure base facing the bearing base.

5. The press-fit device of claim 1 , wherein the pressure base is provided with a plurality of vac-sorb holes.

6. The press-fit device of claim 1 , wherein two guiding tracks are disposed at two sides of the piston rod, respectively.

7. The press-fit device of claim 6 , further comprising a stabilizing plate, wherein the stabilizing plate is disposed on the two guiding tracks and is connected to the power cylinder.

8. The press-fit device of claim 1 , wherein the mounting rack is a gantry.

9. The press-fit device of claim 1 , wherein the power cylinder is selected from the group consisting of an oil cylinder and an air cylinder.
