Description
Technical field
The utility model relates to fixture, is specially a kind of nut tensile test fixture.
Background technology
Along with the development of machinery industry, the reliability and the security that connect for guaranteeing, to all the give one's hand requirement of load test of some important bolts, nut, wherein the load that guarantees of tension test is the referee method of nut mechanical property in recent years.The tension test of nut needs special-purpose stretching clamp conventionally, otherwise cannot carry out this testing experiment.Fixture of the prior art, is need to adopt different unit clamps for different nuts, cannot use the V-type jaw of existing testing tool,, and be difficult for guaranteeing stressed along the effect of nut axis.
Utility model content
For problems of the prior art, it is a kind of simple in structure, easy to operate that the utility model provides, adaptable nut tensile test fixture.
The utility model is to be achieved through the following technical solutions:
Nut tensile test fixture comprises a lower link, pedestal and upper connecting rod; Pedestal is tubular setting, and bottom is provided with through hole; Upper connecting rod stretches into pedestal upper opening, and upper connecting rod is connected with pedestal by radially running through the straight pin of pedestal; Lower link stretches into base bottom through hole, and the screw thread of lower link inserting end coordinates with nut, and nut is fastened on above through hole.
Preferably, base interior is also provided with cushion block, and cushion block central authorities are provided with central through hole, and the diameter of central through hole is greater than the diameter of lower link inserting end, is less than or equal to the diameter of base bottom through hole.
Further, it is cylindric that pedestal is, cushion block be with base internal wall be slidably matched cylindric.
Further again, the part that upper connecting rod stretches into pedestal be with base internal wall be slidably matched cylindric.
Preferably, the radius of the retained part of lower link is more than or equal to and the diameter stretching in pedestal with nut mating part.
Compared with prior art, the utlity model has following useful technique effect:
The utility model is by the setting of pedestal, to tested nut, provide test transition, utilization is engaged in the lower link of pedestal bottom and realizes location and the restriction axially and radially to nut, the collaborative test acting force of realizing of upper connecting rod by top can apply tensile load along nut axis direction, accuracy and the reliability of test findings have been guaranteed, while having avoided direct clamping, add the impact of the power of holding on test result, and the destruction to nut structure.
Further, by the setting of cushion block, can guarantee in the stable situation of base construction, to the nut of different size, all can test, only need to change the different cushion block of central through hole and the lower link matching with nut for different nuts, simple to operate, easy to use, with low cost.
Further, by cylindric and columned setting and cooperation, simplified processing on the one hand, be beneficial on the other hand the stressed direction of adjusting nut, can guarantee that cushion block is uniform and stable to the reacting force of nut all directions; The cylinder coordinating by upper connecting rod, has guaranteed its radial location in pedestal.
Further, the footpath that straightens by lower link arranges, guaranteed nut test accurately, and retained part structure is stable.
Accompanying drawing explanation
Fig. 1 is the structural representation described in the utility model example.
Fig. 2 is the vertical view of Fig. 1.
Wherein: 1 is lower link, 2 is cylinder pedestal, and 3 is cushion block, and 4 is nut, and 5 is straight pin, and 6 is upper connecting rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of nut tensile test fixture of the utility model, as shown in Figure 1, comprises lower link 1, pedestal 2 and upper connecting rod 6; Pedestal 2 is tubular setting, and bottom is provided with through hole; Upper connecting rod 6 stretches into pedestal 2 upper openings, and upper connecting rod 6 is connected with pedestal 2 by radially running through the straight pin 5 of pedestal 2; Lower link 1 stretches into pedestal 2 bottom through-holes, and the screw thread of lower link 1 inserting end coordinates with nut 4, and nut 4 is fastened on above through hole.In this preferred embodiment, as shown in Figure 1, pedestal 2 inside are also provided with cushion block 3, and cushion block 3 central authorities are provided with central through hole, and the diameter of central through hole is greater than the diameter of lower link 1 inserting end, is less than or equal to the diameter of pedestal 2 bottom through-holes.Wherein, as shown in Figure 2, pedestal 2 is cylindric, cushion block 3 be with pedestal 2 inwalls be slidably matched cylindric; The part that upper connecting rod 6 stretches into pedestal 2 be with pedestal 2 inwalls be slidably matched cylindric.Can be convenient to installation and the assembling of nut, and being fixed of upper connecting rod and pedestal 2; And as shown in Figure 1, the radius of the retained part of lower link 1 is more than or equal to and stretches in pedestal 2 and the diameter of nut 4 mating parts.
During use, according to nut 4 specifications, select corresponding cushion block 3 and lower link 1, first the threaded portion of lower link 1 is passed to the through hole of pedestal cylindraceous 2 bottoms, then after the threaded portion that cushion block 3 is placed on to lower link 1 through center through hole, nut to be measured 4 and the threaded engagement of lower link 1 are tightened, can be reliably that nut 4 is fixing, finally use straight pin 5 radially to run through setting, upper connecting rod 6 is connected with cylindric pedestal 2, by upper connecting rod 6 and lower link 1, is clipped in V-type jaw and starts test; Mobile adjustment by cushion block 3 and upper connecting rod 6 guarantees to apply assurance tensile load along nut 4 axis directions, guaranteed accuracy and the reliability of test findings.Nut for different size only need be changed cushion block and lower link, and the utility model project organization is simple, is easy to processing, and easy to operate, cost is low, is applicable to common V-type jaw.
