Abstract
The utility model relates to a tensile test fixture structure for a power lithium battery. The tensile test fixture structure comprises a round handle inserted into a test fixture structure, and is characterized in that a fixed clamp splice is arranged on the round handle, the fixed clamp splice and a movable clamp splice form a clamp main body and are in open-close hinged connection with each other, and the movable clamp splice is clamped with the fixed clamp splice through a set screw. The tensile test fixture structure has the benefits that the tensile test fixture structure is suitable for a special tensile tester, is convenient to assemble and disassemble, and facilitates size adjustment so as to be universally used for examination test of various batteries in different sizes, guarantees the internal examination test of high-capacity batteries, meets the quality and performance process requirements during later production and manufacture of the high-capacity batteries, has a positioning function, and can greatly improve the examination test efficiency, simplify the production technology and procedures, lower the product production and manufacture costs and improve the product assembly quality, thereby greatly improving the product market competitiveness.
Description
Technical field
The utility model belongs to lithium battery verification test instrument, relates in particular to a kind of power lithium-ion battery tensile test tool structure.
Background technology
The reliability of lithium battery, security are technological difficulties in great-capacity power battery manufacturing process.Especially large capacity laminated battery plate is in manufacturing process, and there is very large problem in test.The test fixture form that the laminated battery plate tensile test adopts at present is a lot.Because large capacity laminated battery plate dimension volume is large, be not easy to move and easily cause short circuit.Urgently need a kind ofly for laminated battery plate Special pull test fixture structure, to solve existing test problem.
The utility model content
The utility model is in order to overcome deficiency of the prior art, and a kind of power lithium-ion battery tensile test tool structure is provided, and is convenient to dismounting, and is convenient to regulate the general multiple differently sized batteries verification test of size energy.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of power lithium-ion battery tensile test tool structure, comprise the round handle that inserts the test fixture structure, it is characterized in that: described round handle is provided with fixedly fixture block, fixedly fixture block and movable clip block form chuck body, and described movable clip block is the open-close type chain connection with fixing fixture block, and described movable clip block is by holding screw and fixedly fixture block clamping.
Described fixedly fixture block shape of cross section is rectangular in shape, described square fixedly radially is provided with the circular groove with opening on the horizontal sides of fixture block, described movable clip block upper surface radially is provided with circular protrusion, and described circular protrusion is pegged graft into described circular groove, make movable clip block and fixedly fixture block be chain connection.
Described movable clip block and fixedly fixture block lower end inwall be respectively equipped with the pointed tooth that prevents slippage.
Beneficial effect: be applicable to the Special pull test machine and use, be convenient to dismounting, and be convenient to regulate the general multiple differently sized batteries verification test of size energy.Play guaranteeing role for high capacity cell internal inspection test, can meet the quality and performance technological requirement that high capacity cell was manufactured in the later stage, this structure also is designed with positioning function simultaneously, can greatly improve check survey formula efficiency, simplify production technology, operation, reduce the cost of manufacture of production and product, improve product assembly quality, greatly improve the competitiveness of product in market.
