Abstract
The utility model relates to a clamp for detecting the tensile force of a chain, which can be installed on an electronic universal tester fixing sleeve when matched with an I-shaped connecting column for use. The clamp for detecting the tensile force of the chain comprises a half fixed block, a half clamping head and a fixed block sleeve. A cavity is arranged inside the half fixed block, and openings are arranged at both ends; the half clamping head is clamped and sleeved at the end part of the chain and arranged at the first end of the cavity; and the fixed block sleeve is sleeved outside the half fixed block, wherein one end of the I-shaped connecting column is installed at the second end of the cavity, and the other end extends out of the half fixed block and is installed on the electronic universal tester fixing sleeve. The utility model ensures that a stress is not added to the chain in testing, thereby ensuring that the detection of the tensile force of the chain has reliable testing results.
Description
Technical field
The utility model relates to a kind of anchor clamps that are used to detect, and particularly relevant for a kind of anchor clamps that detect chain pull.
Background technology
The minimum stretch load of chain is the important indicator in chain production and the use at present, its test method is: effectively the tension segment is made up of 5 free chain links at least, and the segment two ends should guarantee not produce extra-stress with the connection of material test machine grip holder on chain part.
The tensile test anchor clamps that chain uses are have netted or have the anchor clamps of convex side that use on the traditional puller system.Because the chaining anchor clamps difference that different producers adopts, because of the anchor clamps improper use, the chain link place that occurs easily being connected with chuck damages, and causes invalidate the test, influences the test findings of tensile load.
The utility model content
Extra-stress not on chain part when the purpose of this utility model provides a kind of warranty test, thus guarantee the anchor clamps of the detection chain pull of test findings reliability.
For reaching above-mentioned purpose, the utility model proposes a kind of anchor clamps that detect chain pull, comprise Hough fixed block, Hough chuck and fixed block cover.Hough fixed block inside has cavity, and two ends all have opening; Hough chuck chuck is in the end of chain, and is arranged on first end of above-mentioned cavity; The fixed block cover is sleeved on the outside of Hough fixed block.The utility model and worker's type joint pin can be installed on the electronic universal tester fixed cover when being used, wherein worker's type joint pin one end is installed in second end of cavity, and the other end extends to outside the Hough fixed block and is installed on the electronic universal tester fixed cover.
In the utility model, the inner shaft of Hough chuck radially is provided with the bearing pin draw-in groove to being provided with the carrier bar groove.
In sum, Hough stationary fixture of the present utility model is simple to operate, has effectively solved chain and has detected the problem that occurs data exception in the pulling force.

Embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Fig. 1 is the assembling synoptic diagram of the anchor clamps of detection chain pull.Fig. 2 a is the front view of the Hough chuck of the anchor clamps of detection chain pull.Fig. 2 b is the right view of the Hough chuck of the anchor clamps of detection chain pull.Fig. 2 c is the vertical view of the Hough chuck of the anchor clamps of detection chain pull.The Hough chuck was clamped the synoptic diagram of chain when Fig. 2 d was use.Fig. 3 a is the front view of the Hough fixed block of the anchor clamps of detection chain pull.Fig. 3 b is the vertical view of the Hough fixed block of the anchor clamps of detection chain pull.Fig. 4 is the cut-open view of the Hough fixed block cover of the anchor clamps of detection chain pull.
Please also refer to Fig. 1 to Fig. 5, the anchor clamps 10 that detect chain pull comprise Hough chuck 1, Hough fixed block 2 and fixed block cover 3.Hough fixed block 2 inside have cavity 21, and two ends all have opening 2a and 2b.Hough chuck 1 chuck is in the end of chain L, and is arranged on first end of cavity.Fixed block cover 3 is sleeved on the outside of Hough fixed block 2.
Shown in Fig. 2 b and 2c, Hough chuck 1 is provided with carrier bar groove 11 in the axial direction, radially is provided with bearing pin draw-in groove 12.During use, the bearing pin of chain L is stuck in the bearing pin draw-in groove 12, and carrier bar is embedded in carrier bar groove 11, the end of chain L can be fixed in the Hough chuck 1 when two parts of Hough chuck 1 close.
During use, Hough chuck 1 is set in the end of sample chain L, Hough chuck 1 is arranged on an end of the cavity 21 of Hough fixed block 2, and fixed block cover 3 is sleeved on the outside of Hough fixed block 2.One end 20a of worker's type joint pin 20 is installed in the other end of cavity 21, and the other end 20b of worker's type joint pin 20 is installed on the electronic universal tester fixed cover, and this end of chain L is with regard to installation like this.Equally, the other end of sample chain L also is fixed on the electronic universal tester fixed cover by identical method, can carry out tension test like this.Chain L destroys to be considered to occur in and no longer is accompanied by when the chain elongation on first that load increases, i.e. " load-stretching " the summit of figure.If destroy when occurring in, then think this invalidate the test with Hough chuck 1 connection place.Tensile test is considered to failure test, can not re-use through the chain after the tensile test.
In sum, the fixture operation of detection chain pull of the present utility model is simple, and is easy to use, effectively solved chain and detected the data exception problem that occurs in the pulling force.
Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
