Description
1, affiliated technical field
The utility model relates to a kind of pretension big machinery part usefulness, can directly install to connect ultrasound bolt detector, and a plurality of pretension parameters of bolt can directly detect the multistage push fastener of the band detection interface of monitoring synchronously.
2, background technique
For pretension big machinery part bolt, all be not have the interface of detection bolt at present, promptly do not have the detection interface of construction bolt detector.Therefore directly detecting synchronously of its a plurality of pretension parameters monitored, all can't adopt the bolt detector that directly links with it directly to carry out synchronously, and can only be by detecting the relevant middle pretension parameter of its relevant pre-clamping tool of monitoring, realize indirectly the back as calculated, promptly can only carry out the monitoring of substep indirect detection.Do not have the basic skills that detects the monitoring of a plurality of pretension parameter substep of interface bolt indirect detection at present and have two kinds:
1) pretension parameter substep indirect detection monitoring method in the middle of the hydraulic elongator
During application specific hydraulic elongator pretension bolt, adopt hydralic pressure gauge to detect hydraulic elongator hydraulic tensioning nut hydraulic system pretension hydraulic coupling value, this hydraulic coupling is on duty with the pretension bolt cross-section area, and indirect detection goes out bolt pretightening as calculated; Measure present position, hydraulic elongator hydraulic tensioning nut pretension front and back size with length measuring instrument simultaneously, indirect detection goes out bolt pretension elongation as calculated.
2) pretension parameter substep indirect detection monitoring method in the middle of the hydraulic torque wrench
During application specific hydraulic torque wrench pretension bolt, adopt hydralic pressure gauge to detect hydraulic torque wrench hydraulic jack hydraulic system pretension hydraulic coupling value, this hydraulic coupling is on duty with hydraulic torque wrench hydraulic cylinder piston cross-section area, the gained product multiply by hydraulic torque wrench arm of force length again, and indirect detection goes out the bolt prefastening torque as calculated; Measure present position, hydraulic torque wrench pretension sleeve pretension front and back size with length measuring instrument simultaneously, indirect detection goes out bolt pretension elongation as calculated.
Do not have detection interface bolt and use the method that above-mentioned two kinds of substep indirect detection are monitored its a plurality of pretension parameters, exist bolt pretension supplemental characteristic accuracy, conformity poor, can not carry out accurate pretension to bolt, influence high request big machinery part preload Technique performance and quality; Slow with the pretension assembling speed, inefficient defective.
3, summary of the invention
Detect interface bolt pretension supplemental characteristic accuracy for solving present nothing, conformity is poor, can not carry out accurate pretension to bolt, influences high request big machinery part preload Technique performance and quality; Slow with the pretension assembling speed, inefficient drawback, it is a kind of with the multistage push fastener that detects interface that the utility model provides, and detects at it a kind of ultrasound bolt detector that can directly detect a plurality of pretension parameters of monitoring bolt synchronously can directly be installed on the interface.During the multistage push fastener pretension, use this detector, a plurality of pretension parameters of bolt can directly detect monitoring synchronously.
The technological scheme that the utility model technical solution problem is adopted is: use a kind of multistage push fastener with the detection interface, it is made up of cylindrical stud bolt, super pad, multistage push nut and multistage push bolt.Cylindrical stud bolt is made cylindrical in the middle of it; Screw thread is made at two; At a head thread end face, be shaped on the exigent minute surface of a surface roughness and detect interface.This detects interface, can provide cylindrical stud bolt pretension parameter information for ultrasound bolt detector magnetic detection probe transmits, can connect ultrasound bolt detector magnetic detection probe for installing again, make the magnetic detection probe can rely on himself magnetic, itself and detection interface tightly are pulled together, thereby make it can detect the pretension parameter information that detects the cylindrical stud bolt that the interface transmission provides, realize its a plurality of pretension parameters are directly detected monitoring synchronously; At other end screw thread end face, be shaped on hexagonal socket cap in, during for the cylindrical stud bolt of mounting or dismounting in the hexagonal manual wrench it is turned.Cylindrical stud bolt one head thread and other end screw thread appellation and position are interchangeable.At screw thread position, other end, be used for first conjunction of mounting strap screw; At the intermediate cylindrical position, be used to install second conjunction; At a head thread position, the super pad of installed inside, and its second reference level is adjacent to mutually with second conjunction, first reference level; The multistage push nut is installed in the outside, and makes its second reference level near super pad first reference level.Super pad is made by alloy material, and two reference levels have extreme hardness and excellent toughness, and its first and second reference level appellation and position are interchangeable.The multistage push nut, on its first reference level, be shaped on a plurality of axial circular hole that becomes the concentric circle equal angles to distribute with its main screw, be shaped on a plurality of internal thread multistage push screws that vertically penetrate coaxial with it in its lower end, associated multistage push bolt is housed above it, what of its quantity are decided on the size of multistage push nut, and first and second reference level appellation of multistage push nut and position are interchangeable.The multistage push bolt is made cylindrical in the middle of it; Make hexagon head for one, it is turned for manual wrench; Screw thread is made in the other end, its screw thread end face contacts with super pad first reference level, rely on it to withstand on the axial jacking force that is produced on super pad first reference level, can be cylindrical stud bolt pretension, can in the pretension process, it not rotated again, guarantee that the detection interface of one head thread end face is unaffected with connecting with detection of ultrasound bolt detector magnetic detection probe.During the cylindrical stud bolt of pretension, adopt manually or pneumatic wrench repeatedly turns all multistage push bolts on the multistage push nut, rely on its other end screw thread end face, withstand on super pad first reference level, axial pushing tow that the multistage push nut produced is made a concerted effort and with cylindrical stud bolt pretension.The pretightening force that it produced, pretension stress and pretension elongation three pretension parameter informations, then by popping one's head in the joining ultrasound bolt of the detection interface detector magnetic detection of one head thread end face, after directly detecting synchronously, with detected three pretension parameter informations, information transmission lead after testing, directly synchronous transfer detects the information translation display screen to ultrasound bolt detector, directly detects synchronously to show and monitoring.
The beneficial effects of the utility model are: during the bolt pretension, the a plurality of pretension parameters of bolt can directly detect monitoring synchronously, it is accurately consistent to have bolt pretension supplemental characteristic, can carry out accurate pretension to bolt, greatly improve high request big machinery part assembly pretightening comprehensive technical performance and quality; Quick with the pretension assembling, the remarkable advantage that efficient greatly improves.
