The fixed seat 1 is arranged at the lower end of the T-shaped pull rod 1, the threaded hole equipped nut 1 is fixedly mounted inside the lower side of the fixed seat 1 through thread, the upper end of the T-shaped pull rod 2 is provided with the fixed seat 2, the unthreaded hole equipped nut 2 is mounted inside the upper side of the fixed seat 2 through thread, the screw passes through the threaded hole and is then in fixed connection with the threaded hole, the upper end of the T-shaped pull rod 1 is fixedly connected to a detection machine upper clamping holder, and the lower end of the T-shaped pull rod 2 is fixedly connected to a detection machine lower clamping holder. The clamping device for screw external thread failure strength testing provided by the invention can support the use of a common universal material testing machine to detect the failure strength of a standard screw, and has the advantages of flexible and convenient clamping, good replaceability, and safe and reliable operation and use process.
Description
Technical field
The invention belongs to intensity detection technical field, relate to a kind of fixture that detects, be specifically related to a kind of screw rodThe test clamp of external screw thread failure intensity is tightly installed.
Background technology
Master screw, bolt, with advantages such as it are simple in structure, inexpensive, are widely used in each rowIn each industry, but a large amount of master screw, bolt of using just need to carry out sampling Detection to its failure intensity,But general factory and enterprise does not all have master screw, bolt there is no special checkout equipment, thereby cannotIt is detected, cause and do not meet standard-required and often make because of master screw, bolt failure intensityThread connection lost efficacy, and in serious situation, also likely caused security incident.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of external thread of screw is providedFailure intensity test clamp is tightly installed, and itself and common universal testing machine support the use and can detect markThe failure intensity of accurate screw rod, reasonable in design, simple in structure, clamping is flexible, and commutativity is good, behaviourDo use procedure safe and reliable, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of external thread of screw lost efficacy strongDegree test clamp is tightly installed, and comprises symmetrically arranged T shape pull bar one and T shape pull bar two, and its feature existsIn: also comprise symmetrically arranged holder one and holder two and symmetrically arranged screw one and screwTwo; Described T shape pull bar one lower end is provided with holder one, and described holder one lower inner part is passed through spiral shellLine is installed with screw with threaded hole, and described T shape pull bar two upper ends are provided with holder two,Described holder two upper interior are installed with the screw two with unthreaded hole by screw thread, and described screw rod is wornAfter crossing described unthreaded hole, be fixedly connected with described screwed hole, on described T shape pull bar one upper end and detection machine, press from both sidesHold seat and be fixedly connected with, described T shape pull bar two lower ends are fixedly connected with grip slipper under detection machine.
Above-mentioned external thread of screw failure intensity test clamp is tightly installed, and it is characterized in that: described T shapeOn pull bar one upper end and described detection machine, grip slipper is threaded connection.
Above-mentioned external thread of screw failure intensity test clamp is tightly installed, and it is characterized in that: described T shapeUnder pull bar two lower ends and described detection machine, grip slipper is threaded connection.
The present invention compared with prior art has the following advantages:
(1) the tight device of this external thread of screw failure intensity test clamp can with common universal material testingMachine supports the use the failure intensity of examination criteria screw rod or bolt.
(2) it is very reasonable that design is tightly installed in this external thread of screw failure intensity test clamp, structure letterSingle, clamping is flexible.
(3) tightly to install commutativity good in this external thread of screw failure intensity test clamp, and operator makesWith in process, safe and reliable.
(4) a lot of parts of the tight device of this external thread of screw failure intensity test clamp are all convenient to raw very muchProduce, buy, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
A kind of external thread of screw failure intensity test clamp as shown in Figure 1 is tightly installed, and comprises that symmetry establishesThe T shape pull bar 1 of putting and T shape pull bar 29, also comprise symmetrically arranged holder 1 and fixingSeat 27 and symmetrically arranged screw 1 and screw 25; Described T shape pull bar one 1 lower ends arrangeHave holder 1, described holder one 3 lower inner part are installed with 4-1 with threaded hole by screw threadScrew 1, described T shape pull bar 29 upper ends are provided with holder 27, described holder 27Upper interior is installed with the screw 25 with unthreaded hole 5-1 by screw thread, and described screw rod 6 is through instituteAfter stating unthreaded hole 5-1, be fixedly connected with described T shape pull bar one 1 upper ends and detection with described screwed hole 4-1On machine, grip slipper 2 is fixedly connected with, and under described T shape pull bar 29 lower ends and detection machine, grip slipper 8 is fixingConnect.
In the present embodiment, on described T shape pull bar one 1 upper ends and described detection machine, grip slipper 2 passes through spiral shellLine connects, and under described T shape pull bar 29 lower ends and described detection machine, grip slipper 8 is threaded connection,Be threaded conveniently, safely, reliably.
The course of work of the tight device of external thread of screw failure intensity of the present invention test clamp is: as Fig. 1 instituteShow, first by tested screw rod 6 upper ends through after the unthreaded hole 5-1 of screw 25 with the screw thread of screw 1Hole 4-1 is fixedly connected with, and then screw 1 is fixed on to holder one 3 lower ends, by solid screw 25Fix on holder 27 upper ends, finally T shape pull bar 1 and T shape pull bar 29 are connected to inspectionOn survey machine, under grip slipper 2 and detection machine on grip slipper 8, start detection machine can carry out spiral shell to screw rod 6Line failure intensity detects.
According to screw 1 and the screw 25 of the diameter of screw rod 6 to be detected and model making corresponding size,Just can carry out test for tensile strength to the screw rod of different model 6.
The above, be only preferred embodiment of the present invention, not the present invention imposed any restrictions, allAny simple modification, change and the equivalence of above embodiment being done according to the technology of the present invention essenceStructural Transformation, all still belongs in the protection domain of technical solution of the present invention.
