DETAILED DESCRIPTION

[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

When the target workpiece is placed, the pressing assembly 410 moves downward until the target workpiece is pressed to press and assemble the target workpiece. In this way, the target workpiece does not need to be manually carried and knocked, which not only reduces the labor intensity, but also increases the assembly efficiency of the bearing outer ring.

[0032] Referring to Figures 1 to 9 The application provides a press-fitting device, which comprises a support frame 100, a press-fitting platform 110 arranged on the support frame 100, a transfer mechanism 200 arranged on the support frame 100, wherein the transfer mechanism 200 comprises a positioning assembly 210 and a material taking assembly 220, a material carrying component 300 for carrying target workpieces, the positioning assembly 210 is movably arranged along a first direction to block and position the material carrying component 300, the material taking assembly 220 is movably arranged along a predetermined track to transfer the target workpieces to the press-fitting platform 110, and a material pressing mechanism 400 arranged on the support frame 100, wherein the material pressing mechanism 400 comprises a press-fitting assembly 410 arranged above the press-fitting platform 110, and the press-fitting assembly 410 is movably arranged along a vertical direction to press-fit the target workpieces.

Since the hydraulic pump rear cover has different specifications, the pressing head 412 and the connecting joint 411 are detachably connected, which facilitates the replacement of the pressing head 412 to adapt to hydraulic pump rear covers of different specifications, so it is not necessary to design a special pressing mechanism for each specification of the rear cover, which greatly reduces the complexity and cost of the equipment. In addition, the connecting joint 411 and the connecting hole 4120 are clearance fit, which can provide a certain floating space for the pressing head 412.

[0035] Further, the pressing head 412 and the connecting joint 411 are connected by locking bolts 414, wherein the pressing head 412 is provided with threaded holes, the connecting joint 411 is provided with an annular groove, the locking bolts 414 are sequentially arranged in the threaded holes and the annular groove, and the locking bolts 414 are threadedly connected with the threaded holes, so that there is a certain gap between the connecting joint 411 and the connecting hole 4120, and the locking bolts 414 are provided in plurality, the threaded holes are provided in plurality, the plurality of threaded holes are arranged at intervals along the circumference of the pressing head 412, and the plurality of locking bolts 414 are arranged one-to-one with the plurality of threaded holes.

The combination of the floating joint 430 and the connecting joint 411 enables the pressing head 412 to have a certain floating capacity during the pressing process, so as to automatically adapt to the slight positional deviation of the workpiece and ensure the pressing precision. Meanwhile, the guide rod 460 is arranged in the guide channel of the mounting frame body 440, which provides accurate guidance for the vertical movement of the pressing head 412, avoids the deflection or shaking of the pressing head during the pressing process, and further improves the stability and reliability of the pressing. The telescopic driving rod of the first driving component 420 can efficiently drive the pressing head 412 to perform the pressing action, and the design of the floating joint 430 ensures that the connection between the driving rod and the pressing head is firm and has a certain floating space.
