Abstract
The utility model relates to a chain tensioning clamp for an all-purpose testing machine. The chain tensioning clamp for the all-purpose testing machine comprises an upper clamp body and a lower clamp body. The upper clamp body and the lower clamp body are provided with a reversely herringbone groove and a herringbone groove respectively. Chain stop blocks are respectively installed in the reversely herringbone groove and the herringbone groove respectively. The smallest distance between the chain stop blocks of the upper clamp body and the smallest distance between the chain stop blocks of the lower clamp body are respectively smaller than the width of a chain clamped by the chain tensioning clamp. Compared with the prior art that a planar chuck is directly used for clamping the chain, the chain tensioning clamp for the all-purpose testing machine is not prone to slippage in the clamping process, the clamping force can be adjusted automatically along with change of testing force, clamping is stable and reliable, and the accuracy of a tensioning test is improved.

Background technology
In today of rapid economic development, no matter be government bodies, science and techniques of defence department, business unit, universities, or the requirement of performance, outward appearance, quality and the cost of ordinary consumer to product is all more and more higher, and especially product quality has had higher requirement.For the instrument and meter production industry of testing product quality and product material property, when being faced with better opportunity and development, also face new challenges.
Chain tensile test equipment is the mechanical property in order to test loop chain and anchor chain, carries out Breaking load test and the drag load test of anchor chain and loop chain according to international and national standard.In prior art, chain tension test is mostly by means of universal testing machine, and the structural style of chain tensile test equipment has three folder stretching clamps and wedge shape stretching clamp.Due to the particularity of chain structure, directly utilize plane chuck clamping chain, the contact portion area of chain and plane chuck is little, and retaining part easily skids, the wearing and tearing that can accelerate plane chuck when use even damage, and also affect the reliability of its tension test.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of chain stretching clamp being applied on universal testing machine, can realize at the trial the firm clamping to chain, guarantees the accuracy of chain tension test.
The technical scheme that the utility model addresses the above problem is as follows:
Be applied to the chain stretching clamp on universal testing machine, comprise clamp body and lower clamp body,
It is characterized in that:
Described upper clamp body is offered herringbone groove, described lower clamp body is offered the splayed groove that becomes mirror image symmetry with the herringbone rectangular channel of upper clamp body, in described herringbone groove and splayed groove, be separately installed with the chain block of form fit with it, the beeline between the chain block on upper and lower clamp body is less than the width of the chain that will clamp.
As further improvement, on described upper clamp body, offer the N shape groove for placing chain ends, on lower clamp body, offer the U-lag for placing chain ends.Like this, in process of the test, chain ends is firmly blocked by block and N shape groove or U-lag, can not depart from block.
Described N shape groove, U-lag connect with herringbone groove, splayed groove respectively.
Further again, described chain block middle part offers groove along its length, is provided with the soket head cap screw that is arranged on clamp body or lower clamp body in described groove.Adopt this structure block to move, be convenient to adjust the distance between adjacent blockers according to the specification of chain sample, realize the clamping to different size chain sample.
As preferred version, described herringbone groove and splayed groove shape are all rectangle.
As shown in Figure 3, the utility model is directly connected with base and the moving beam of universal testing machine by screw in use, its course of work is, before test, select suitable clamp body according to the specification of sample, by parallel the pre-clamping chain link of the chain fluting place as for clamp body, utilize two chain blocks and its formation wedge structure under the effect of gravity, to realize pre-clamping, apply at universal testing machine and draw tighter and tighter under the effect of pulling force; Thereby complete the tension test of chain, its test is carried out according to relevant test standard to control procedure.
The utility model directly utilizes compared with plane chuck clamping chain with existing, and its beneficial effect is:
1, the utility model clamping firmly, is difficult for skidding at clamping process, and clamping force can regulate voluntarily along with the variation of test force, and clamping process reliability is high, has increased the accuracy of tension test.
2, the spacing between chain block can be adjusted, therefore can test the chain sample of different size, and highly versatile,
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of upper clamp body in the utility model.
Fig. 3 is that the utility model is arranged on the structural representation on universal testing machine.
In figure: 1, upper clamp body; 1 ', lower clamp body; 2, chain block; 2a, groove; 3, soket head cap screw; 4, herringbone groove; 4 ', splayed groove; 5, chain sample; 6, N shape groove; 6 ', U-lag; 7, moving beam; 8, oil cylinder; 9, base.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 and Fig. 2, a kind of chain stretching clamp being applied on universal testing machine, comprise clamp body 1 and lower clamp body 1 ', upper and lower clamp body is symmetrical arranged, described upper clamp body is offered herringbone groove 4, described lower clamp body is offered the splayed groove 4 ' that becomes mirror image symmetry with herringbone rectangular channel, in herringbone groove and splayed groove, be separately installed with the chain block 2 mating with groove shape, the beeline between the chain block on upper clamp body or lower clamp body is less than the width of the chain that will clamp.
On described upper clamp body, offer the N shape groove 6 for placing chain ends, on lower clamp body, offer the U-lag 6 ' for placing chain ends.Like this, in process of the test, chain ends is firmly blocked by block and N shape groove or U-lag, can not depart from block.
As shown in Figure 2, described N shape groove, U-lag connect with herringbone groove, splayed groove respectively.
Described chain block middle part offers groove 2a along its length, is provided with the soket head cap screw 3 that is arranged on clamp body or lower clamp body in described groove.Adopt this structure block to move, be convenient to adjust the distance between adjacent blockers according to the specification of chain sample, realize the clamping to different size chain sample.
Described herringbone groove and splayed groove shape are all rectangle.
The utility model is directly connected with base and the moving beam of universal testing machine by screw in use, its course of work is, before test, select suitable clamp body according to the specification of sample, by parallel the pre-clamping chain link of the chain fluting place as for clamp body, utilize two chain blocks and its formation wedge structure under the effect of gravity, to realize pre-clamping, apply at universal testing machine and draw tighter and tighter under the effect of pulling force; Thereby complete the tension test of chain, its test is carried out according to relevant test standard to control procedure.This structure is compared with directly utilizing plane chuck clamping chain, and its clamping process is difficult for skidding, and clamping force can regulate voluntarily along with the variation of test force, and clamping process reliability is high, increases the accuracy of its tension test.
