Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a tool for printing positioning points on a handlebar of an electric vehicle. Background Art

[0002] Electric bicycles are increasingly used by the public for their green, environmentally friendly and energy-saving features. As an important component of electric bicycles, the quality of the handlebars plays a significant role in the comfort and safety of riders.

[0003] The handlebar is a tube component formed by bending and welding steel pipes. It is symmetrical in center. The middle of the middle bending section is fixed to the frame through a vertical pipe, and the handlebars are installed at the ends of the horizontal sections on both sides. In order to facilitate the installation of other parts in the subsequent assembly process, it is necessary to punch holes on the horizontal section of the handlebar where the parts are to be installed, and mark them in advance as positioning points to ensure the accurate installation position of the parts during assembly and improve installation efficiency.

[0004] The traditional marking point method is operated manually. The operator marks the punching position, holds the handlebars and adjusts the handlebar position to align the punching point with the falling position of the punch press, and then punches. When the punching position is changed in this process, the handlebar position must be adjusted again. Therefore, the operation efficiency is low, the work intensity is also high, and the punching position is visually observed, which is not accurate enough. Summary of the invention

[0005] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a tool for printing positioning points of handlebars of an electric vehicle which can ensure accurate punching point positions and improve work efficiency.

[0006] The utility model adopts the following technical scheme to solve the technical problems: a tool for printing positioning points of handlebars of an electric vehicle, comprising a bottom plate, a bottom plate having a lower die fixed thereon, guide rods being fixed on the lower die at a distance from each other on the left and right sides, an upper die being slidably provided on the guide rods, and the upper die and the lower die being fitted together to clamp the horizontal section of the handlebar during printing; a printing template being provided above the upper die, springs being connected between the four corner ends of the printing template and the upper die, the upper end of the guide rod being slidably matched with the printing template, a punching rod being fixed on the printing template, the lower end of the punching rod being slidably matched with the upper die and corresponding to the position of the printing point on the horizontal section of the handlebar; a punching plate being fixed on the upper end face of the printing template, and a connecting block being fixedly connected to the punch head of the punching machine being fixed on the punching plate; a limiting sleeve being installed on the bottom plate located at the rear side of the lower die, and the end face of the horizontal section of the handlebar being abutted against the end face of the limiting sleeve.

[0007] The upper surface of the lower mold is provided with lower semicircular grooves at intervals on the left and right sides, and the lower surface of the upper mold is provided with upper semicircular grooves corresponding to the lower semicircular grooves at intervals on the left and right sides. When the upper mold and the lower mold are fitted, the horizontal section of the handlebar is clamped between the lower semicircular groove and the upper semicircular groove.

[0008] A limiting module is fixed on the bottom plate at the front side of the lower mold, and two cross-shaped limiting arc grooves are opened on the upper surface of the limiting module. When printing, the bevel edge of the curved part of the handlebar is clamped in the limiting arc groove.

[0009] Two groups of punching rods are fixed on the printing template at a distance from each other on the left and right sides, and two punching rods in each group are distributed front and back.

[0010] The beneficial effect of the utility model is that the utility model realizes positioning of the end face of the horizontal section of the handlebar by arranging a limiting sleeve on the rear side of the lower mold, and the horizontal section of the handlebar is clamped by the upper and lower molds, so that a mark can be made on the horizontal section of the handlebar as a positioning point for installing other components, the operation is convenient and quick, and the marking position is accurate.
