Abstract

The utility model relates to a battery box bottom plate girth welding frock, including support frame, a plurality of gyration die clamping cylinder, a plurality of location cylinder, a plurality of locating pieces, place the bottom plate on battery box chassis and splice each frame around the bottom plate at the top surface of support frame gyration die clamping cylinder around the outside at each frame, gyration die clamping cylinder's piston end transverse connection depression bar, the vertical pressure head of adorning admittedly of outer end of depression bar, the pressure head is pressed in the seam crossing of frame and bottom plate, adorns location cylinder or locating piece admittedly between two adjacent gyration die clamping cylinder, the locating piece is relative with location cylinder position. The utility model discloses a position that a plurality of pressure heads treat welding with the battery box chassis is pushed down, and rotatory pressure head lets out the position when the welding machine passes through. And the pressing heads of other point positions are not moved, so that the flatness of the whole bottom plate is ensured, and the phenomena of bulging and the like are avoided.

Description

Battery box bottom plate girth welding tool

Technical Field

The utility model belongs to the welding field relates to the circumferential weld technique, especially a battery box bottom plate circumferential weld frock.

Background

The chassis structure of the new energy automobile aluminum alloy battery box is shown in figure 1 and is of a special-shaped structure and composed of a plurality of frames 2 and a bottom plate 1, and the frames and the bottom plate are welded together through a welding machine after being respectively processed. Because the battery box chassis is bigger, how to guarantee that the levelness of a plurality of frames and bottom plate welding back bottom plate is unchangeable both be the utility model discloses the technical problem who solves.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a battery bottom of the case dish girth welding frock of structural design science, reasonable, through fixed a plurality of frames simultaneously.

The utility model provides a technical scheme that technical problem adopted is:

the utility model provides a battery box chassis girth welding frock, includes support frame, a plurality of gyration die clamping cylinder, a plurality of location cylinder, a plurality of locating piece, places the bottom plate on battery box chassis and splices each frame around the bottom plate at the top surface of support frame gyration die clamping cylinder around the outside at each frame, gyration die clamping cylinder's piston end transverse connection depression bar, a pressure head is adorned admittedly to the outer end of depression bar is vertical, the pressure head is pressed in the seam crossing of frame and bottom plate, adorns location cylinder or locating piece admittedly between two adjacent gyration die clamping cylinder, the locating piece is relative with location cylinder position.

And the top end of the pressure head is provided with threads, the end part of the pressure rod connected with the pressure head is provided with a threaded hole, and the pressure head is meshed with the pressure rod and is fixed through a nut.

And the bottom end of the pressure head is a cake-shaped pressing block.

Moreover, the pressing block is sleeved with a rubber sleeve.

And, the support frame be bilayer structure, correspond the convex position system of frame and let the hole on upper support.

The utility model has the advantages that:

the utility model discloses a position that a plurality of pressure heads treat welding with the battery box chassis is pushed down, and rotatory pressure head lets out the position when the welding machine passes through. And the pressing heads of other point positions are not moved, so that the flatness of the whole bottom plate is ensured, and the phenomena of bulging and the like are avoided.

Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

The utility model provides a battery box bottom plate girth welding frock, includes support frame 5, a plurality of gyration die clamping cylinder 6, a plurality of location cylinder 7, a plurality of locating piece 8, places bottom plate 1 on battery box chassis and splices each frame 2 around the bottom plate at the top surface of support frame gyration die clamping cylinder around the outside at each frame, gyration die clamping cylinder include depression bar 3, a pressure head 4 is adorned admittedly to the outer end of depression bar is vertical, the pressure head is pressed in the seam crossing of frame and bottom plate. And a positioning cylinder or a positioning block is fixedly arranged between two adjacent rotary clamping cylinders, and the positioning block is opposite to the positioning cylinder.

The top end of the pressure head is provided with threads, the end part of the pressure rod connected with the pressure head is provided with threaded holes, and the pressure head is meshed with the pressure rod and is fixed through nuts.

The bottom end of the pressure head is a round cake-shaped pressing block, and a rubber sleeve is sleeved on the pressing block, so that the chassis of the battery box is prevented from being scratched.

The support frame is of a double-layer structure, and the upper layer and the lower layer are connected and supported through the stand column. And a yielding hole is formed in the position, corresponding to the protruding position of the frame, on the upper-layer support, so that the levelness of the rear bottom plate is ensured by assembling the bottom plate and the frame.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
