Abstract
The invention discloses a circumferential tensile strength experimental clamp for a glass fiber reinforced plastic conduit. An upper connection head is connected with an upper connection plate through a pin; the upper connection plate is connected with an upper clamping plate through a pin and a locking shaft; the upper clamping plate is connected with an upper separation disk through a pin and a positioning shaft; a lower connection head is directly connected with a lower clamping plate; the lower clamping plate is connected with a lower separation disk through a positioning shaft; a safety hole is formed in each of the upper separation disk and the lower separation disk; the separation disks are fixed on the clamping plates through safety screws. Due to the arrangement, the experimental clamp can be used for safely and simply perform an experiment of the circumferential tensile strength of the glass fiber reinforced plastic conduit.
Description
Technical field
The present invention relates to a kind of test fixture, relate to specifically a kind of glass fiber reinforced plastics conduit hoop tensile strength test fixture.
Background technology
Glass fiber reinforced plastics conduit material, after the finished product that rolls off the production line, all needs its hoop tensile strength to test at present, determines whether glass fiber reinforced plastics conduit performance conforms to quality requirements.Because the diameter of glass fiber reinforced plastics conduit is relatively large, traditional grip of testing machine does not have to be applicable to the requirement of its test.Microcatheter technology condition part 2 for DL/T 802.2-2007 electronic cables: glass fiber reinforced plastics cable duct tube has been stipulated the hoop tensile strength of separator disk method mensuration glass fiber reinforced plastics conduit, but does not provide concrete test fixture.
Summary of the invention
The object of this invention is to provide a kind of glass fiber reinforced plastics conduit hoop tensile strength test fixture, realize the test of glass fiber reinforced plastics conduit hoop tensile strength.
Technical scheme of the present invention is: the present invention includes upper and lower connector, upper junction plate, upper and lower clamping plate, upper and lower separator disk.
Being connected of described upper and lower clamping plate and upper and lower separator disk also has safety screw except locating shaft.
Each described Xiao Huozhou side is provided with a screw, to prevent its loosening or slippage.
Advantage of the present invention is: the test of the very convenient safe hoop tensile strength of realizing glass fiber reinforced plastics conduit of whole mechanism, when doing the test of glass fiber reinforced plastics conduit hoop tensile strength, not only to make the sample of different size, and the sample of same size will be done test repeatedly, common test fixture will be many times the upper and lower separator disk of dismounting, and separator disk quality is larger, inconvenient dismounting back and forth, this brings huge trouble to testing crew, the present invention is by the ingenious utilization of several pins and axle, do not need to dismantle upper and lower separator disk, only need to loosening tighten several nuts just can realize handling sample and replace with, lower separator disk, greatly facilitate testing crew, saved the time, upper junction plate, lower union joint, the screw of the lateral layout of upper and lower clamping plate, anti-shotpin or axle loosening, greatly possible assurance the exploitativeness of fixture, the design of slotted hole leaves certain space to the installation of sample, prevents that upper and lower separator disk collision from causing fixture and device damage simultaneously, on upper and lower clamping plate, have two positioning shaft holes, can facilitate the replacing of the separator disk of different-diameter size, separator disk is comprised of two semicircles, can design plurality of specifications, and separator disk can be made trace around axle and within the scope of safety screw and swing, to eliminate the distortion of alignment error or sample itself.
Accompanying drawing explanation
Now the present invention is further illustrated by reference to the accompanying drawings.
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the side view of figure mono-.
In figure, 1 lower union joint, 2 times separator disks, 3 lower plates, 4 train wheel bridges, 5 safety screws, separator disk on 6,7 nuts, 8 holding screws, 9 upper binding heads, 10 pins, 11 upper junction plates, 12 lock shafts, 13 locating shafts.
Embodiment
As shown in the figure, upper binding head 9, lower union joint 1 are respectively installed to testing machine relevant position.
Upper binding head 9 is connected with upper junction plate 11 by pin 10.Upper junction plate 11 is connected with train wheel bridge 4 with lock shaft 12 by pin 10, and lock shaft 12 two ends are fastening by nut 7.Train wheel bridge 4 connects upper separator disk 6, and locating shaft 13 plays the effect that connects both, and two ends are fastening by nut 7 equally.
Lower union joint 1 is connected lower plate 3 by pin 10 with lock shaft 12, and lower plate 3 connects lower separator disk 2 by locating shaft 14.Between upper and lower separator disk and clamping plate, be all provided with safety screw 5.
The present invention completes the installation of test fixture and the clamping of sample by following steps:
Step 1: upper and lower connector is installed to the corresponding upper and lower Connection Block of testing machine, regulates upper and lower connector concentric simultaneously;
Step 2: install separator disk 6.Locating shaft 13 is through positioning shaft hole, and in connection, separator disk 6, on clamping plate, then tightens safety screw 5;
Step 3: the lower plate 3 with safety screw hole is installed.Insert pin 10 and lock shaft 12, connect lower plate 3 with safety screw hole in lower union joint 1 one sides;
Step 4: lower separator disk 2 is installed.Insert locating shaft 13, connect lower separator disk 2 and lower plate 3, tighten safety screw 5;
Step 5: each holding screw 8 that tightens side;
Step 6: adjust testing machine, make the distance between upper and lower separator disk moderate.Materials and be installed on upper and lower separator disk.Remaining upper and lower clamping plate are installed.Tighten the nut of each axle.
Step 7: starting characteristics test machine, hoop tensile sample, until sample destruction, the load while recording sample destruction;
Step 8: change sample.Take off the sample of destruction, unclamp successively four positive nuts, take off positive upper and lower clamping plate, sample is installed, repeating step six, seven;
Step 9: change separator disk.Unclamp successively four positive nuts, take off positive upper and lower clamping plate, unclamp the safety screw of upper and lower separator disk, take off separator disk, the separator disk needing is installed, repeating step two, four, six, seven;
Step 10: clamper for disassembling.
