High-precision charger shell end face drilling machining device

Abstract

The invention provides a high-precision charger shell end face drilling machining device. The device comprises a workbench, an installing frame, a first driving mechanism, N drilling mechanisms, N fixing mechanisms and a controller; the installing frame is provided with a distance measuring sensor used for detecting a distance value between the installing frame and the workbench in real time; each drilling mechanism comprises M drilling components and prepressing sleeves, wherein the M drilling components are all installed on the installing frame and circumferentially distributed, drill bits of all the drilling components face the workbench, the prepressing sleeves are located under the installing frame, connected with the installing frame through multiple reset springs and provided with M guiding grooves, and a first guiding hole used for allowing the corresponding drill bit to penetrate through is formed in each guiding groove in the extending direction of the drill bit; M fixing platforms used for fixing a charger shell are arranged at the end, close to the installing frame, of a fixing base, and the controller is connected with the first driving mechanism and the distance measuring sensor. The high-precision charger shell end face drilling machining device is accurate in drilling and positioning performance, high in precision and drilling efficiency, good in machining effect and high in product quality.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a high-precision device for drilling holes on the end face of a charger housing. Background technique [0002] Now, technologies related to electric vehicles driven by using electric power, which is green energy, are rapidly developing. Most electric vehicles include an electric motor that generates rotational force, a battery that supplies electricity to the motor, an inverter that controls the RPM of the motor, a battery charger that charges the battery with electricity, and a low-voltage DC / DC converter for electric vehicles . The performance of the electric vehicle charger also has a certain influence on the use of electric vehicles. The main circuit components of the electric vehicle charger are all arranged in the casing, and the casing plays an important protective role. During the manufacturing process of the charger housing, a drilling process is often r...

Problems solved by technology

Traditionally, when drilling holes on the charger shell, usually first draw a dot or a cross line on the position of the charger shell where the hole needs to be drilled as a mark, then hold the charger shell and place it on the bench drill, and place the The drill bit is aligned with the marks drawn in advance to drill holes one by one. This kind of drilling method not only cannot guarantee the accuracy of the drilling position, but also has low work efficiency.
