[0039] In order to solve the limitations of the prior art, this embodiment provides a technical solution, and the technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0040] See attached Figure 1-2 The utility model is mainly for press-fitting operations. In conventional press-fitting equipment, a turntable is generally used to rotate and move product components loaded to different workstations to the press-fitting workstations. Therefore, there is generally no hard support at the bottom of the turntable to support it. During the press-fitting operation, the product components on the turntable need to withstand greater pressure. The utility model sets a jacking mechanism 300 to convert the horizontal movement of the jacking power unit 301 into the lifting movement of the jacking plate 200, thereby achieving hard support.

[0041] See attached Figure 3-5A press-fitting lifting mechanism 300 includes: a lifting power unit 301 and a lifting unit 302, wherein the lifting power unit 301 is used to provide power to drive the lifting unit 302 to perform horizontal reciprocating movement. It can be understood that the lifting power unit 301 adopts a horizontal moving component, which can be a horizontal cylinder, a horizontal motor screw assembly or other horizontal moving components; the lifting unit 302 is used to convert the horizontal movement into a switching action of hard support or no support at the bottom of the lifting plate 200. It can be understood here that hard support or no support is mainly used in occasions where press-fitting operations are required or when the press-fitting operations are completed and no bottom support is required, and during the lifting action, the lifting unit 302 and the lifting plate 200 are installed in rolling contact, and the rolling contact installation can not only achieve the hard support effect, but also minimize friction.

[0042] See attached Figure 1-5 The lifting power unit 301 is installed on the workbench top plate 100. Here, the workbench top plate 100 is mainly used as a mounting platform for installing various components. A plurality of linear guide components 307 are installed between the lifting plate 200 and the workbench top plate 100. Here, the linear guide component 307 can be a linear bearing or a guide block and a guide rod component or other components with a linear motion function. The lifting part 302 is installed on the power end of the lifting power part 301 and is driven by it to make horizontal reciprocating movements. The lifting part 302 and the workbench top plate 100 are installed in rolling contact. A linear guide assembly 307 is provided to ensure the stability of the lifting plate 200 during the lifting process and prevent the lifting plate 200 from translational displacement. By providing the lifting power part 301 and the lifting part 302, the lifting power part 301 drives the lifting part 302 to make horizontal reciprocating movements, while achieving hard contact between the top of the lifting part 302 and the bottom surface of the lifting plate 200, thereby achieving hard support for the lifting plate 200 during press installation. Different from the lifting structure in the related art, the lifting positioning stability and accuracy of the present application are higher.

[0043] See attached Figure 6 and 7The lifting part 302 includes a lifting body 3021, one end of which is installed on the power end of the lifting power part 301, and the bottom of the lifting body 3021 is installed in rolling contact with the workbench top plate 100. It can be understood that the lifting body 3021 is configured as a rectangular parallelepiped with a hollow interior, and the upper surface of the lifting body 3021 includes a lifting support surface 3026 and an initial surface 3025, and the height of the initial surface 3025 is less than the height of the lifting support surface 3026, wherein the lifting support surface 3026 is located on the side away from the lifting plate 200, and the initial surface 3025 is located on the side close to the lifting plate 200, and in the initial state, the initial surface 3025 is partially located below the lifting plate 200. A transition surface 3024 is set at the connection between the lifting support surface 3026 and the initial surface 3025. The transition surface 3024 is an inclined surface with an angle of α, 0°<α<90°, and the optimal choice here is that α is 45°. The purpose of setting the transition surface 3024 here is to facilitate the lifting body 3021 to move toward the direction close to the lifting plate 200, so that the lifting plate 200 can be lifted and lowered more stably, making the lifting process smoother. The jacking support surface 3026 is provided with four upper limit holes 3022, in which the upper rotating shaft 304 is rotatably installed, and the upper roller 303 is fixedly installed with the upper rotating shaft 304. The bottom surface of the jacking body 3021 is provided with four lower limit holes 3023, in which the lower rotating shaft 305 is rotatably installed, and the lower roller 306 is fixedly installed with the lower rotating shaft 305. It can be understood here that the upper limit holes 3022 have a supporting effect on the upper rotating shaft 304, and the lower limit holes 3023 have a limiting effect on the lower rotating shaft 305 and the lower roller 306, so as to better ensure the stability of the horizontal operation of the jacking body 3021. The upper limit hole 3022 and the lower limit hole 3023 are both set as U-shaped holes, the opening end of the U-shaped hole of the upper limit hole 3022 is connected to the jacking support surface 3026, and the opening end of the U-shaped hole of the lower limit hole 3023 is connected to the bottom surface of the jacking body 3021. Four upper rollers 303 are rotatably installed on the top of the jacking body 3021, the highest point of the upper roller 303 is higher than the upper surface of the jacking body 3021, and the distance H from the highest point of the upper roller 303 to the upper surface of the workbench top plate 100 is greater than the distance L between the bottom surface of the jacking plate 200 and the upper surface of the workbench top plate 100.Four lower rollers 306 are rotatably installed at the bottom of the lifting body 3021. The lower rollers 306 are installed in rolling contact with the upper surface of the workbench top plate 100. The specific structure of the lifting body 3021 is set, and the top and bottom of the lifting body 3021 are supported by rolling contact, which can not only reduce the friction generated during relative movement, but also achieve the purpose of hard support; by setting the shape and size relationship of the top surface of the lifting body 3021, it is convenient for the lifting part 302 to contact and support the lifting plate 200 more smoothly when moving in the horizontal direction, and at the same time, it can more effectively improve the structural strength of the lifting part 302, and by setting the specific shapes of the upper limit hole 3022 and the lower limit hole 3023, it is convenient to limit the upper roller 303 and the lower roller 306 without limiting the rotation of the upper roller 303 and the lower roller 306, which is convenient for installation and maintenance.

[0044] When the jacking mechanism 300 of the utility model is working, in the initial state, the jacking power unit 301 is in the original position, and the initial surface 3025 of the jacking body 3021 is partially located below the jacking plate 200. At this time, the jacking body 3021 has no contact with the jacking plate 200. When the jacking plate 200 needs to be press-fitted and subjected to force, the jacking power unit 301 is actuated to drive the jacking body 3021 to move in the horizontal direction close to the jacking plate 200, and the initial surface 3025 continues to move in the direction close to the jacking plate 200. The jacking plate 200 slowly moves upward along the transition portion, the jacking support surface 3026 and the upper roller 303. Finally, the upper roller 303 of the jacking body 3021 rolls smoothly along the jacking plate 200 to achieve hard support for the bottom of the jacking plate 200. When the press-fitting operation is completed, the jacking power unit 301 is actuated to retract the jacking body 3021.
