Description
Technical field
The utility model relates to lithium battery production equipment technical fields more particularly to a kind of dynamic lithium battery pole to connect
Head metallographic test clamping device.
Background technique
The advantages that lithium battery is with its high-energy density, long-life, be widely used in electric car, standby power system,
In micro-grid energy storage system, dynamic lithium battery contains the structures such as core, electrolyte, shell, cover board, on the cover board, in order to enhance
The connection type of electric conductivity, pole and pressing plate is in such a way that riveting is welded with and connects, at design end, need to pole welding point into
Metallographic structure and the Pool of pole welding point are observed in row verifying；Since welding point is in flat structure, seen under light microscopic
When examining weld seam section metallographic, it is difficult standing, can not be observed；Traditional solutions are connect using the butt welding of metallographic mounting press
Connector carries out edge sample, facilitates polishing and om observation, and when the method carries out batch metallographic test, there are at high cost and low efficiency
Problem.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of dynamic lithium battery poles to connect
Head metallographic test clamping device.
The utility model proposes a kind of dynamic lithium battery pole welding point metallographic test clamping device, including clamping
Block, grip block are equipped with the first groove, and the first groove floor is provided inwardly with the second groove, and the first groove is along the section of depth direction
It is kissed greater than the second groove along the section of depth direction, the first groove inner wall and the second groove inner wall and the welding point surface
It closes.
In the utility model, the dynamic lithium battery pole welding point metallographic test clamping device proposed is not required to butt welding
Connector carries out edge sample processing, has saved cost, has improved metallographic testing efficiency.

Specific embodiment
As shown in Figs. 1-5, Fig. 1 be the utility model proposes a kind of dynamic lithium battery pole welding point metallographic test folder
Hold the axonometric drawing of mechanism, Fig. 2 be the utility model proposes a kind of dynamic lithium battery pole welding point metallographic test clamping machine
The side view of structure, Fig. 3 are the axonometric drawing of cover plate of power battery, and Fig. 4 is that cover plate of power battery splits the schematic diagram under state, Fig. 5
The schematic diagram of clamping device is placed on for welding point.
Referring to Fig.1-2, the utility model proposes a kind of dynamic lithium battery pole welding point metallographic test clamping device,
Including grip block, grip block is equipped with the first groove 1, and 1 bottom surface of the first groove is provided inwardly with the second groove 2, and the first groove 1 is along depth
Spend direction section be greater than the second groove 2 along the section of depth direction, 1 inner wall of the first groove and 2 inner wall of the second groove with it is described
Welding point surface profiles.
In the utility model, the dynamic lithium battery pole welding point metallographic test clamping device proposed is not required to butt welding
Connector carries out edge sample processing, has saved cost, has improved metallographic testing efficiency.
Referring to Fig. 3-5, the use process of the dynamic lithium battery pole welding point metallographic test clamping device of the present embodiment
In, first welding point is radially cut, pole circular weld section is exposed, the sample for taking cutting to obtain later will
Metallographic observes cutting plane polishing, polishing, corrosion and the cleaning of sample, then is placed into grip block, and the first groove 1 and second is recessed
Slot 2 and specimen surface coincide, so that sample be kept to stablize, metallographic inspection surface is in a horizontal state, and it is molten to be put into light microscopic observation weld seam
Pool size shape and tissue topography.
Using the dynamic lithium battery pole welding point metallographic test clamping device in the present embodiment, it is not required to Welded Joints
Edge sample processing is carried out, cost has been saved, has improved metallographic testing efficiency.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
