Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0038] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.
[0039] Unless otherw...

The invention discloses a press-fitting device, an auxiliary press-fitting mechanism and an auxiliary press-fitting method. The auxiliary press-fitting mechanism comprises a press-fitting body, a locating part and a movement assembly. The open size of a clamp groove is firstly determined according to the thickness of the box wall of a gear box. An oil pipe connecting nozzle is arranged on a fixedpart, the press-fitting body moves towards the gear box till the box wall of the gear box is located in the clamp groove, and then the position of the box wall of the gear box in the clamp groove is determined according to the position of an oil nozzle mounting hole in the gear box. Finally, the press-fitting body is driven through the movement assembly to move relative to the box wall of the gearbox, and then the oil pipe connecting nozzle is mounted in the oil nozzle mounting hole. Compared with press fitting of traditional ground press devices, the auxiliary press-fitting mechanism does not need to fix the whole gear box and only needs to directly carry out press-fitting treatment on local parts of the gear box. Thus, by means of the auxiliary press-fitting mechanism, mounting of the oil pipe connecting nozzle is more convenient.
Description
technical field [0001] The invention relates to the technical field of electric drive processing, in particular to a pressing device, an auxiliary pressing mechanism and an auxiliary pressing method. Background technique [0002] Traditionally, in the processing of new energy electric drive systems, the gearbox is an important mechanical component, and an oil pipe connection nozzle for connecting the oil circuit needs to be installed on the gearbox. However, due to the high installation accuracy of the gearbox, when installing the oil pipe connection nozzle of the gearbox, the gearbox needs to be placed on a specific workbench, and then press-fitted by a press device, so that the oil pipe connection nozzle Installation is very inconvenient. Contents of the invention [0003] Based on this, it is necessary to provide a pressing device, an auxiliary pressing mechanism and an auxiliary pressing method, which can make the installation of the oil pipe connecting nozzle very co...
