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 formed by cylinder head bolt, super pad, multistage push bolt and hexagon head bolt or by cylinder head bolt, super pad, multistage push bolt.Cylinder head bolt is made cylindrical in the middle of it; Make screw thread for one; 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 cylinder head 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 cylinder head bolt that the interface transmission provides, realize its a plurality of pretension parameters are directly detected monitoring synchronously.At the intermediate cylindrical position, the super pad of installed inside; And make its first reference level near socket cap second reference level, the outside is used to install first conjunction, and its first reference level or second reference level are adjacent to mutually with super pad second reference level, super pad is made by alloy material, two reference levels have extreme hardness and excellent toughness, and its first and second reference level appellation and position are interchangeable; At a head thread position, be used for second conjunction of mounting strap screw.In cylinder head bolt socket cap first reference surface center, be shaped on an internal thread screw or an inner hexagonal hole, associated hexagon head bolt is housed on center screw, and its hexagon head inner side surface is adjacent to mutually with socket cap first reference level.Hexagon head bolt or inner hexagonal hole, manual wrench or inner hexagon spanner turn it during for the mounting or dismounting cylinder head bolt; Around socket cap first reference surface center screw or inner hexagonal hole, being shaped on its center screw or inner hexagonal hole becomes the concentric circle equal angles to distribute, the a plurality of internal thread multistage push screws that penetrate vertically, associated multistage push bolt is housed above it, what of its quantity are decided on cylinder head bolt socket cap size.Make screw thread in the middle of the multistage push bolt, make hexagon head for one, for spanner it is turned, the other end is made cylindrical; Or one made screw thread, be shaped on inner hexagonal hole at the threaded tip center, for inner hexagon spanner it is turned, the other end is made cylindrical, its end face contacts with super pad first reference level, relies on it to withstand on the axial jacking force that is produced on super pad first reference level, can be the cylinder head bolt pretension, it is not rotated in the pretension process, 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 pretension cylinder head bolt, adopt manually or pneumatic wrench repeatedly turns all multistage push bolts on the socket cap, rely on the cylindrical end face in its other end to withstand on super pad first reference level, axial pushing tow that the cylinder head bolt socket cap produced is made a concerted effort and with the cylinder head 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.
