[0016] The present application provides a new energy automobile aluminum alloy battery shell trepanning device and process, which has the following beneficial effects: 1) The present application first transports the battery shell to be trepanned to the trepanning end through the feeding module, so that the position to be trepanned on the mounting plate corresponds to the position of the drill rod, and then drives the servo motor to descend through the lifting module. In the descending process, since the drill rod is in the position embedded in the protective sleeve, the protective sleeve on the outside of the drill rod first abuts against the mounting plate.

DETAILED DESCRIPTION

[0019] The specific embodiments of the present application are described in detail below, but it should be understood that the scope of protection of the present application is not limited by the specific embodiments.

[0020] Example 1

[0021] As Figures 1 to 3 shown, the new energy vehicle aluminum alloy battery shell trepanning equipment provided by the embodiment of the present application comprises a feeding module, which is used to convey the battery shell 2 to be trepanned to a trepanning end; The two sides of the battery shell 2 are symmetrically fixed with mounting plates 201; it should be noted that the mounting plates 201 need to be trepanned in this embodiment, and the number and density of the trepanning are not limited, which can meet the actual application requirements.

[0022] As an embodiment of the present embodiment, the two sides of the trepanning end are respectively provided with drilling assemblies 6 for trepanning the mounting plates 201; Please refer to Figures 4-6 , specifically, the drilling assembly 6 comprises a drill rod 612, which is fixed with the output end of a servo motor 601 through a drive shaft 602; in actual application, the servo motor 601 of the present embodiment can be started, and the servo motor 601 drives the drill rod 612 to rotate synchronously through the drive shaft 602, so as to be used for drilling.

[0023] The two side servo motors 601 are connected with lifting modules for driving the lifting of the two side servo motors 601; specifically, the lifting modules can drive the lifting of the servo motors 601, and then synchronously drive the lifting of the two side drill rods 612, so as to adjust the height of the drill rods 612 and realize the drilling.

[0024] In order to avoid the metal debris generated in the drilling from splashing into the battery shell 2, in the embodiment, a protective sleeve 603 is arranged outside the drill rod 612, and the protective sleeve 603 of the embodiment is in a cylindrical structure, and the protective sleeve 603 is connected with the shell of the servo motor 601 through a first elastic mechanism. In the initial state, the drill rod 612 is in the position embedded in the protective sleeve 603; it can be explained that, first, the battery shell 2 to be drilled is conveyed to the drilling end by the feeding module, so that the position to be drilled on the mounting plate 201 corresponds to the position of the drill rod 612, and then the servo motor 601 is driven to descend by the lifting module, and in the process of descending, since the drill rod 612 is in the position embedded in the protective sleeve 603, the protective sleeve 603 outside the drill rod 612 first abuts against the mounting plate 201, and as the servo motor 601 continues to descend driven by the lifting module, the protective sleeve 603 compresses the first elastic mechanism and generates elastic force, and under the action of the elastic force of the first elastic mechanism, the effect of pressing and positioning the mounting plate 201 can be realized, so that the stability of the battery shell 2 is higher during the subsequent drilling, so as to avoid the phenomenon that the battery shell 2 deviates or shakes under the torsional force of the drill rod 612, and the drilling precision is ensured; at the same time, since the protective sleeve 603 is in the state of being sleeved on the drill rod 612, the metal debris generated in the drilling process is always limited in the protective sleeve 603 and cannot splash into the battery shell 2, so the protection effect is effectively improved, and correspondingly, the coolant of the drill rod 612 also collects in the protective sleeve 603 during the drilling process, and cannot flow to the surroundings, so as to facilitate subsequent collection and recycling.

[0025] In addition, the opening end of the embodiment is also provided with a monitor for monitoring the conveying position of the battery shell 2, so as to ensure the drilling precision of the mounting plate 201, and correspondingly, the specific type and structure of the monitor are not limited, and the actual application requirements can be met.

[0029] In the present embodiment, the feeding module further comprises a translation mechanism and a lifting mechanism 102, the translation mechanism is used for horizontally moving the battery shell 2 on the transfer trolley 1 to the opening end, and the lifting mechanism 102 is used for driving the bottom plate 103 to ascend and descend; It can be explained that, when the transfer trolley 1 of the present embodiment moves to the feeding end, the battery shell 2 at the top end is flush with the opening end, so that the battery shell 2 at the top end can be horizontally moved to the opening end by the translation mechanism, when the battery shell 2 at the top end is removed, the bottom plate 103 can be lifted by the lifting mechanism 102 of the present embodiment, so that the battery shell 2 at the next layer can be lifted to be flush with the opening end, so as to be fed again by the translation mechanism, thereby realizing the effect of automatic feeding one by one.

[0030] As an implementable manner of the embodiment, the translation mechanism comprises translation assemblies 5 arranged symmetrically, driving ends of the translation assemblies 5 are fixedly arranged with a bearing plate 501 of a supporting mounting plate 201, the bearing plate 501 is fixedly arranged with L-shaped supports 502 for limiting the mounting plate 201, wherein the bearing plate 501 is provided with a plurality of groups of through holes 505 for passing through the drill rod 612; it can be explained that when the transfer trolley 1 moves to the feeding end, the translation mechanism of the embodiment can drive the bearing plate 501 to move towards the direction of the transfer trolley 1, at this time the lifting mechanism 102 can drive the bottom plate 103 to rise by a certain distance, so as to make the mounting plate 201 interfere with the L-shaped supports 502, because there is a certain spacing between the two adjacent battery shell 2 on the transfer trolley 1, the bearing plate 501 can move to the bottom of the mounting plate 201, and then the lifting module drives the bottom plate 103 to descend by a certain distance, so that the two mounting plates 201 can just fall on the bearing plate 501, and the L-shaped supports 502 just engage with the side of the mounting plate 201, achieving the effect of limiting the mounting plate 201, finally the translation mechanism drives the bearing plate 501 and the limited battery shell 2 to move towards the hole opening end, achieving the feeding effect, at the same time, when the mounting plate 201 completes the hole opening once, the feeding module drives the battery shell 2 to move by a predetermined distance, achieving the effect of hole opening one by one.

[0031] In addition, the spacing of the two supporting plates 105 in the embodiment is less than the spacing of the two bearing plates 501, so as to avoid interference between the bearing plate 501 and the supporting plate 105.

[0032] It should be noted that the translation assembly 5 of the embodiment can adopt a synchronous belt transmission mechanism or a screw nut transmission mechanism, which is not limited in the embodiment to meet the actual application requirements.
