[0003] Currently, a pneumatic press-fitting machine is used to press the cylindrical sleeve into the mounting hole on the gasket. During the press-fitting process, only the pressing action is achieved; a corresponding side inspection module is lacking. After press-fitting, a separate inspection process is required, increasing the production steps and restricting the production cycle.

[0004] The existing technical solutions mentioned above have the following drawbacks: after the pressing is completed, a separate testing process is required, which increases the production steps and restricts the production cycle. Summary of the Invention

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] Reference Figure 1 and Figure 2 This application discloses a sleeve pressing machine, including a frame 110, a support 120, a pressing fixture 130, a booster cylinder 140, a pressure sensor 151, a displacement sensor 152, a color sensor 153, and a positioning detection sensor 154. The frame 110 is provided with a base plate 111 and a top plate 112. The support 120 is mounted on the base plate 111, and its top surface supports a gasket 200. The pressing fixture 130 is vertically movably mounted on the top plate 112 and is used to press a sleeve 300 into a mounting hole on the gasket 200. The booster cylinder 140 is mounted on the top plate 112, and its output end is connected to the pressing fixture 130 via the pressure sensor 151. The displacement sensor 152's detection head is connected to the pressing fixture 130 and is used to detect the displacement of the pressing fixture 130. During the pressing process, pressure sensor 151 detects the pressure applied to the press 130 by the booster cylinder 140, and displacement sensor 152 detects the downward displacement of the press 130. Color sensor 153, mounted on the base plate 111, detects the color of the gasket 200. Position detection sensor 154, also mounted on the base plate 111, detects whether the sleeve 300 is properly pressed into place. This combination of multiple detection signals effectively determines the pressing effect. Overall, it reduces production steps and labor costs, increases production cycle time, and facilitates tracing the causes of defects.

[0029] It should be noted that the cylindrical sleeve 300 needs to be press-fitted into the two mounting holes of the gasket 200. Therefore, there are two of each of the press 130, the booster cylinder 140, the pressure sensor 151, the displacement sensor 152, and the position detection sensor 154 to ensure pressing efficiency and detection efficiency.

The follower rods 161 of the two guide frames 160 are fixedly connected to the detection heads of two displacement sensors 152 respectively. During the vertical movement of the two pressing fixtures 130, the two guide frames 160 serve both as guides and as connectors between the pressing fixtures 130 and the displacement sensors 152. By detecting the downward displacement of the two guide frames 160, the downward displacement of the two pressing fixtures 130 can be determined.

[0031] Preferably, refer to Figure 4Each guide frame 160 includes a follower rod 161, an upper connecting plate 162, a lower connecting plate 163, three guide rods 164, and three bushings 165.

The two bar feeding mechanisms 170 are respectively used to supply sleeves 300. The two transfer mechanisms 180 are respectively used to transfer the sleeves 300 from the corresponding bar feeding mechanism 170 to the corresponding mounting holes on the gasket 200.

The pneumatic gripper 185 is fixedly connected to the output end of the lifting cylinder 184 and is used to grip or release the sleeve 300. When the pneumatic gripper 185 grips the sleeve 300, the first linear module 182 can drive the second linear module 183 to move along the X-axis direction, thereby causing the lifting cylinder 184, the pneumatic gripper 185, and the sleeve 300 to move along the X-axis direction. The second linear module 183 can drive the lifting cylinder 184 to move along the Y-axis, thereby moving the pneumatic gripper 185 and the sleeve 300 along the Y-axis. The lifting cylinder 184 can drive the pneumatic gripper 185 to move along the Z-axis, thereby moving the sleeve 300 along the Z-axis.

Each of the two position adjustment mechanisms 191 is equipped with a booster cylinder 140, which is used to drive the corresponding booster cylinder 140 to move along the X-axis and Y-axis directions, thereby driving the corresponding pressing fixture 130 to move along the X-axis and Y-axis directions. The position of the pressing fixture 130 can be adjusted according to the position of the mounting hole on the gasket 200, so that the pressing fixture 130 is directly above the mounting hole.
