A battery pack bracket punching device for a motorcycle

Abstract

The invention relates to the field of machining, in particular to a motorcycle battery pack bracket punching device which comprises a workbench and a motor, and further comprises a first chain wheel,a second chain wheel, a third chain wheel, a fourth chain wheel and a sliding plate, wherein a drill bit is connected onto the motor; a closed chain is connected among the first chain wheel, the second chain wheel, the third chain wheel and the fourth chain wheel; an L-shaped pressing plate is rotationally connected with a chain link of the chain; a torsional spring is arranged on the part, rotationally connected with the chain link, of the pressing plate; both the top and the side of a motor shell are capable of being propped against the pressing plate; the sliding plate is capable of transversely sliding; the motor is vertically and slidably connected onto the sliding plate; a first spring is connected onto the motor; a first telescopic cylinder is arranged on the outer side of the firstspring in a sleeving manner; a second spring is connected onto the sliding plate; a second telescopic cylinder is arranged on the outer side of the second spring in a sleeving manner; and a placementslot used for the placement of a bracket is arranged on the workbench. Through the scheme of the motorcycle battery pack bracket punching device, the automatic movement of the bracket in the drillingprocess can be achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a battery pack bracket punching device for motorcycles. Background technique [0002] Electric motorcycles are powered by batteries. The battery is usually placed in a motorcycle battery pack, which can protect the battery, prevent the battery from being exposed to wind and rain, and improve the service life of the battery. [0003] The motorcycle battery pack bracket is used to support and limit the battery pack. The brackets are usually tubular, and the brackets are connected to each other. A rectangular frame is formed between several brackets to hold the battery pack. [0004] During the production and processing of the bracket, it is usually necessary to drill several holes in the axial direction, and the drilled holes can allow bolts to pass through in the subsequent assembly process, so as to facilitate the stable connection of several brackets. [0005] In the prior...

Problems solved by technology

[0005] In the prior art, after a hole is drilled in the bracket, it is necessary to manually move the bracket so that other parts of the bracket are opposite to the drill bit, and then the drill bit drills holes in other parts of the bracket, so the automatic movement of the bracket cannot be realized, and the operation is more complicated

Moreover, when the bracket is manually moved, it cannot be guaranteed that the distance of the bracket is equal each time, so that the distance between the holes processed on the bracket and the holes has a slight deviation. In this way, when the two brackets are assembled, the holes on the two brackets Unable to be fully aligned, bolt penetration is difficult
