Abstract
The utility model discloses a detection tool for flexibility of a chain. The tool comprises a pedestal which is provided with more than three roller shafts. The three roller shafts, which are adjacent to each other, form three points of an isosceles triangle. The height of the isosceles triangle is greater than or equal to the width of a single chain, and the bottom length of the isosceles triangle is two times greater than or equal to the length of the single chain. A roller is sleeved on each roller shaft and can rotate around the roller shaft. The detection tool for flexibility of a chain is simple in structure and simple in operation, is not liable to miss-detection and false detection, and allows the detection for flexibility of a chain to be fast and convenient.
Description
Technical field
The utility model relates to a kind of chain dirigibility testing tool, and this instrument does not destroy chain link and reaches the GB requirement when detecting the chain dirigibility.
Background technology
The dirigibility of chain is the important technology index in chain production and the use; The dirigibility of chain is related to the normal use of chain; If the dirigibility of chain is bad, then chain cannot dispatch from the factory, so the important indicator that the dirigibility of chain is a chain must be detected before dispatching from the factory.At present, also do not have special instrument that the dirigibility of chain is detected, existing detection method mainly is through range estimation and feel, and this method is prone to produce omission and false retrieval.
The utility model content
The technical matters that the utility model will solve is that existing chain dirigibility detection means is easy to generate omission and false retrieval.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of chain dirigibility testing tool comprises base; Base is provided with the Roller Shaft more than three; Three adjacent Roller Shaft are formed three summits of isosceles triangle, and the height of said isosceles triangle is more than or equal to the width of strand joint, and base length is more than or equal to the twice of strand joint length; Also be socketed with roller on the said Roller Shaft, roller can rotate around Roller Shaft.
Adjacent Roller Shaft is obliquely installed, and can make chain walk around each roller successively along zigzag, and chain link is through roller the time, and no hysteresis phenomenon is qualified, and is defective if the generation sluggishness manifests the dirigibility that this chain link then is described.
As a kind of improvement project of the utility model, also respectively be provided with a fixed via on four angles of base.Through fixed orifice, can base be fixed on the worktable stability when having strengthened pick-up unit work.
Said Roller Shaft number is three.
For ease of maintenance, the replacement of instrument, said base is provided with the jack corresponding with the Roller Shaft shape, and Roller Shaft is inserted in the jack.When Roller Shaft wears up to can not continue to use the time, can extract Roller Shaft out jack, change to new getting final product again.
The utility model has the advantages that: simple in structure, simple to operate, be not easy to produce omission and false retrieval, make that chain dirigibility testing is convenient and swift.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 be Figure 1A-A to cut-open view.
Structural representation when Fig. 3 is the utility model use.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Fig. 1-3; The utility model comprises base 1, and base 1 is provided with three summits that 2, three Roller Shaft of three Roller Shaft 2 are formed isosceles triangle; The height of said isosceles triangle is more than or equal to the width of strand joint; Base length also is socketed with roller 3 more than or equal to the twice of strand joint length on the said Roller Shaft 2, and roller 3 can rotate around Roller Shaft 2.Also respectively be provided with a fixed via 4 on four angles of base 1.Said base 1 is provided with and the corresponding jack of Roller Shaft 2 shapes, and Roller Shaft 2 is inserted in the jack.
During use, the illustrated direction in edge spurs chain to be detected, makes chain pass through each roller 3 successively along zigzag, and chain link is through roller 3 time, and no hysteresis phenomenon is qualified, and is defective if the generation sluggishness manifests the dirigibility that this chain link then is described.
