TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile power battery tray processing, specifically to a battery tray ground aluminum block robot argon arc welding special positioning tool. BACKGROUND
[0002] The power battery tray is an important component for bearing the power battery on the new energy automobile. In order to conduct the generated static electricity to the outside and establish a good electrical property contact between the battery tray and the ground, the safety of the power battery is ensured, and a ground aluminum block needs to be welded on the side of the battery tray as a connecting joint of the ground wire.
[0003] The overall frame of the battery tray is welded by a robot argon arc welding, and when the aluminum block is welded, the aluminum block is small in size, and the ordinary tool fixture is not easy to clamp, so the aluminum block is usually manually spot-welded and pre-fixed to the specified position of the tray, and then full-welding fixation is completed in the overall robot welding process. However, this welding method has the following disadvantages: 1. Manual welding of the pre-positioned aluminum block will cause positional deviation, which is not conducive to the consistency of the battery tray product, and will also affect the accuracy of the subsequent robot full-welding, causing miswelding and missed welding and other phenomena; 2. Additional processes are added, resulting in increased production cost and reduced production efficiency. Therefore, how to quickly and accurately weld the ground aluminum block of the battery tray is a technical problem that needs to be solved by the technical personnel in the field. SUMMARY
[0004] The utility model aims at providing a battery tray ground aluminum block robot argon arc welding special positioning tool, which is special for welding the ground aluminum block on the battery tray, changes the status of needing manual pre-spot-welding fixation, and has the advantages of accurate positioning, convenient operation and the like.
[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0006] A battery tray ground aluminum block robot argon arc welding special positioning tool, the aluminum block welding tool is arranged on the side of the battery tray; the aluminum block welding tool comprises a gas cylinder, the piston rod tail end of the gas cylinder is fixed with a connecting plate, the other side of the connecting plate is fixed with a pressing plate, a fixed pin is arranged on the convex edge of one side of the pressing plate, and the tail end of the fixed pin is embedded in the through hole or groove of the aluminum block.
[0007] By the extension and retraction of the piston rod of the gas cylinder, the fixed pin on the pressing plate is pressed down with the aluminum block and abuts against the surface of the battery tray, after accurate positioning, the robot performs full-welding fixation at the contact position of the aluminum block, and the welding operation is completed without the need for manual spot-welding pre-fixation of the aluminum block.
[0008] The gas cylinder is a three-axis gas cylinder, guide rods are inserted into the guide holes on both sides of the gas cylinder body, one end of the guide rod is fixedly connected with the connecting plate, the other end passes through a cross bar to connect one end of a pull rod, and the other end of the pull rod is hinged to the long hole in the middle of the wrench.
[0009] At the same time that the cylinder piston rod can realize feeding, the function of manual pressing down is increased, which acts in that due to the speed and strength of the pure cylinder piston rod feeding being large, if the aluminum block is quickly impacted on the battery tray frame profile, the impact indentation is easily left, and the appearance of the battery tray is affected. Therefore, after the operator puts the aluminum block on the fixed pin, the wrench needs to be pressed down first, similar to the manual wrench structure of the quick clamp, the aluminum block is pressed down to the position close to the frame through the slow pressing down of the guide rod, and then the three-axis cylinder is ventilated, and the cylinder presses the aluminum block tightly, and the operation can effectively avoid the impact of the aluminum block on the frame.
[0010] Meanwhile, the three-axis cylinder has a more stable feeding path due to the two-side guide rod structure, and after the pressing plate is fixedly connected with the guide rod end, rotation does not occur, so that the aluminum block is more accurately positioned on the battery tray.
[0011] The aluminum block welding tool can be attached to the fixed support or attached to the whole rotary welding tool of the battery tray, and the cylinder body is fixed on the attachment through bolts.
[0012] Usually, the tool can be fixedly installed on the rotary welding tool, and the aluminum block can be welded at the same time when the whole frame of the battery tray is welded, and the welding is completed in one go.
[0013] 1. The utility model is special for the welding of the aluminum block of the grounding end of the power battery tray, changes the operation of needing to pre-point the aluminum block in the original operation, saves the procedure and working hours, improves the production efficiency, and also improves the accuracy of the aluminum block welding.
[0014] 2. The utility model adopts two-section type pressing: manual pressing and then pneumatic pressing, so as to avoid the impact of the quick pressing of the cylinder on the battery frame and avoid the surface damage of the battery tray.
[0015] 3. The utility model is small in size and can be installed on the whole tool device, and is convenient and fast to disassemble and assemble. DRAWINGS
