Description
1, affiliated technical field
The present invention relates to a kind of pretension big machinery part usefulness, connection ultrasound bolt detector can directly be installed, 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 the invention provides a kind of multistage push fastener with the detection interface, 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 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 technical solution problem of the present invention is adopted is: use a kind of multistage push fastener with the detection interface, it is made up of hexagon head bolt, super pad, multistage push nut and multistage push bolt.Hexagon head bolt, the centre is made cylindrical; Make screw thread for one; At the screw thread end face, be shaped on the exigent minute surface of a surface roughness and detect interface, this detects interface, can provide hexagon 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 it can be detected detect the hexagon head bolt pretension parameter information that the interface transmission provides, realize directly detection monitoring synchronously its a plurality of pretension parameters.At the intermediate cylindrical position, be used to install the first and second two pretension conjunctions, and first conjunction, first reference level and hexagon head bolt hexagon head inner side surface are adjacent to; At a head thread position, the super pad of installed inside, 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, its barrel surface, radially equal angles is shaped on a plurality of blind holes, is used to insert pole, manually it is turned; 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 multistage push nut size.First and second reference level appellation of multistage push nut and position are interchangeable.The multistage push bolt, screw thread is made in the centre, make flanged hexagon head for one, the other end is made cylindrical, its cylindrical 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 hexagon 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 hexagon head bolt, adopt manually or pneumatic wrench repeatedly turns all multistage push bolts on the multistage push nut, rely on its cylindrical end face to withstand on super pad first reference level axial pushing tow that the multistage push nut produced made a concerted effort and the hexagon head bolt pretension.The pretightening force that it produced, pretension stress and pretension elongation three pretension parameter informations, after then directly detecting synchronously by the joining ultrasound bolt of detection interface detector magnetic detection probe with one head thread end face, 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 invention has the beneficial effects as follows: 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, has greatly improved high request big machinery part assembly pretightening comprehensive technical performance and quality; Quick with the pretension assembling, the remarkable advantage that efficient greatly improves.
