[0002] At present, the general equipment for pressing gears and bearings on crankshafts is basically a vertical pressing device. In order to ensure that the crankshaft does not deform, the gears or bearings are usually pressed first, and then the workpiece is turned around and the bearings or gears are pressed. Therefore, the pressing machine has two assemblies during the pressing process, which is time-consuming and labor-intensive, affecting production efficiency, and the operators are also tired, affecting operating efficiency.

[0008] Furthermore, the slide rail is an I-shaped structure.

[0009] Furthermore, the two tooling sleeves are arranged horizontally opposite to each other.

[0010] The beneficial effects of the utility model are:

[0011] 1. By changing the vertical up and down press-fitting mode to a horizontal press-fitting mode, the bearing and the gear can be press-fitted at the same time, without the need for two assemblies, thereby reducing labor intensity and improving safety during the workpiece assembly process.

[0012] 2. The tooling sleeve is pushed to slide on the slide rail by the first electric push rod and the second electric push rod, thereby driving the pressing head to move, and then pressing the bearing and the gear onto the crankshaft, saving time and effort.

[0013] 3. The positioning block is connected to the fixing plate by a clamping arrangement, thereby facilitating the removal and installation of the positioning block, and thus facilitating replacement according to crankshafts of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS
