Abstract
The utility model relates to a special fixture for roller chain tension test. When really using the whole set of the fixture, the fixture comprises four fixtures with equal shape and structure. The face of the clamp is a vertical face. The back is an oblique plane contracted from top to bottom. Chimb is provided with the back of the fixture. The lateral face of the fixture is arranged with symmetry. A semicircle protruding strip is horizontally positioned in the lower part of vertical face of fixtures face. When using the utility model to test, the upper head and the lower head of the chain being tested is respectively nipped in the upper and lower fixture. Because the semicircle protruding strip is firmly nip the chain, the chain of the relative big size interface can not up and down slide, it has the advantage of making the test data precision.
Description
Affiliated technical field
The utility model is a kind of roller chain tensile test unit clamp.
Background technology
At present the tensile test anchor clamps that use of chain are have netted or have the anchor clamps of convex side that use on the traditional puller system.Above-mentioned anchor clamps use all cumbersome, and the transposing anchor clamps bother more.Recently the anchor clamps that use on the Material Testing Machine have flexible and convenient to use, change anchor clamps not only soon but also convenient, test data is comparatively correct, but by being the double wedge structure on contacted of what itself and the roller chain, during test when spurring energetically chain easily dragged slip, cause test data inaccurate.
Summary of the invention
Even to be design a kind of when test roller chain pulling force when spurring energetically that chain can not dragged slip yet for the purpose of this utility model, thereby test data roller chain pulling force unit clamp accurately.
The technical solution of the utility model is: a kind of roller chain tensile test unit clamp.It is a kind of improvement to former puller system anchor clamps.The utility model is to make into to a horizontal semicircle cord tissue to outer lug is set on the plane with the contacted face of roller chain above-mentioned, and the convex shape of this raised line is corresponding with the middle female shapes that concaves of two pitch chain bars of roller chain.These anchor clamps are by two groups up and down, and every group is made of symmetrical anchor clamps.
In the utility model when work, will tested roller chain about two is clipped in respectively up and down in the two pairs of anchor clamps, make semicircle raised line aim at recess shapes place in the middle of the two pitch chain bars during clip chain bar, chain is tightly clamped and big thereby make chain when spurring energetically, also can not dragged slip because of surface of contact by what two semicircle raised lines.
Even the utility model has the advantages that to have had when test roller chain pulling force that chain can not dragged slip yet when spurring energetically, thereby test data is accurate.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2, 3: a kind of roller chain tensile test unit clamp.This anchor clamps 1 front 4 is a vertical plane.Next 7 is one from top 2 to following 6 tapered plane that progressively shrinks.Above-mentioned shape can be overlapped the installation that matches of 8 cavity shape with anchor clamps, this structure make anchor clamps 1 can be sleeved in the anchor clamps cover 8 tightly and dismounting very convenient.Anchor clamps 1 back 7 dual-sides are provided with chimb 3, this two chimb 3 also be used for anchor clamps cover 8 in the two groove wringing fits on both sides usefulness is installed, this chimb 3 can not move forward and backward anchor clamps 1 after inserting in the groove in anchor clamps cover 8 to the left and right.These anchor clamps about 1 face structural symmetry.Be horizontally arranged with a semicircle raised line 5 at the Lower Half place of anchor clamps 1 front vertical plane, the convex shape of this semicircle raised line 5 is corresponding with the middle female shapes that concaves of two pitch chain bars of roller chain.This semicircle raised line 5 is used for the jamming roller chain, and the central concave position of two pitch chain bars is clamped by semicircle raised line 5 facing each other during installation.As shown in Figure 4: form by all identical anchor clamps 1 of four block-shaped structures during the actual use of these a whole set of anchor clamps, four anchor clamps divide two groups to be contained in the tensile test machine respectively up and down in two groups of anchor clamps covers, above two wide ends of anchor clamps in the above, below two wide ends of anchor clamps below, the one side that has semicircle raised line 5 in every group is oppositely arranged in twos.
Claims (1)
- A kind of roller chain tensile test unit clamp, a whole set of anchor clamps are made up of all identical anchor clamps of four block-shaped structures, these four anchor clamps divide two groups up and down, every group is made of symmetrical two anchor clamps, the anchor clamps front is a vertical plane, and the back is a tapered plane that progressively shrinks from top to following, and this anchor clamps back dual-side is provided with chimb, face structural symmetry about these anchor clamps is characterized in that: be horizontally arranged with a semicircle raised line at the Lower Half place of anchor clamps front vertical plane.
