Description

Detection QS weld strength test-bed
Technical field
This utility model relates to a kind of weld strength test-bed, particularly relates to a kind of detection QS weld strength Test-bed and test method thereof, it is mainly used in the weld strength test of heavy-duty commercial vehicle separate type QS.
Background technology
For preventing sideways overturning and improving ride comfort, heavy-duty commercial vehicle typically can be equipped with QS.For manufacturing and peace Dress is convenient, and QS is mostly integral type, " U "-shaped.But part heavy-duty commercial vehicle can be according to the sky of each assembly parts Between arrange, in combination with vehicle concrete structure select separate type stabiliser bar, as shown in Figure 1.Separate type stabiliser bar is real by two Heart forging joint is welded with hollow steel pipe.QS shown in accompanying drawing 1 runs at vehicle and constantly bears moment of flexure and moment of torsion, And amplitude is relatively big, weld seam probably ftractures.Thus need badly and develop QS weld strength shown in a set of detection accompanying drawing 1 Test-bed.
Utility model content
Technical problem to be solved in the utility model is to provide one detection separate type horizontal for above-mentioned prior art The test-bed of stabiliser bar weld strength and test method thereof.
The technical scheme in the invention for solving the above technical problem is: a kind of detection QS weld strength examination Testing stand, it includes rigid base, and the side of described rigid base is provided with column assembly, can by one end of QS That shirks is fixed on column assembly, and the other end is removable lining simultaneously is fixed on rectangular tube, interts at described rectangular tube end Rectangle stud is also fixed on rigid base, is symmetrically installed two oscillating bearings, in said two above rectangular tube end simultaneously It is provided with pull pressure sensor on oscillating bearing, is installed with at the middle part of described rectangular tube and to be connected with pull pressure sensor Display, is provided above pressing plate at described rectangle stud, and the two ends of described pressing plate are interspersed with lead, the end of described lead End is fixed on rigid base, and the other end of described pull pressure sensor, leads to threadeding with the pressing plate through rectangle stud Crossing and tighten panel nut and apply moment of torsion to QS, described QS is stable in column assembly by buckling preventing support bar And between rectangular tube.
Compared with prior art, the utility model has the advantage of:
1, cost is relatively low, and operation is the simplest.
2, torsion-testing scope is relatively big, and its test interval is [800,8000] Nm, fully meets testing requirement.
3, accuracy of detection is higher, is 1%, fully meets engineering test demand.
Accompanying drawing explanation
Fig. 1 is the structural representation of the QS in this utility model.
Fig. 2 is the structural representation of this utility model detection QS weld strength test-bed.
Fig. 3 is the enlarged diagram in Fig. 2 at A.
Fig. 4 is the enlarged diagram in Fig. 2 at B.
Wherein: rigid base 1, column assembly 2, QS 3, rectangular tube 4, rectangle stud 5, oscillating bearing 6, tension and compression Force transducer 7, display 8, pressing plate 9, lead 10, panel nut 11, buckling preventing support bar 12.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Fig. 1 Fig. 4, a kind of detection QS weld strength test-bed in the present embodiment, including just Property base 1, is provided with column assembly 2, by specific frock, by one end of QS 3 in the side of described rigid base 1 Removable lining being fixed on column assembly 2, the other end is removable lining simultaneously is fixed on the higher rectangular tube of rigidity 4, described side Shape pipe 4 is mutually perpendicular in same level with QS 3, drives cannelure, at cannelure at described rectangular tube 4 end Interior interspersed rectangle stud 5 is also fixed on rigid base 1, is symmetrically installed two oscillating bearings 6 above rectangular tube 4 end simultaneously, Said two oscillating bearing 6 is provided with pull pressure sensor 7, is installed with and pressure at the middle part of described rectangular tube The display 8 that sensor 7 is connected, is provided above pressing plate 9 at described rectangle stud 5, and the two ends of described pressing plate 9 are interspersed with guiding Post 10, the bottom of described lead 10 is fixed on rigid base 1, the other end of described pull pressure sensor 7 with through rectangle The pressing plate 9 of stud 5, with threaded, applies moment of torsion by tightening panel nut 11 to QS 3, and torque can be by showing Showing that device shows, described QS 3 is stable between column assembly 2 and rectangular tube 4 by buckling preventing support bar 12.
The present embodiment provides the test method of a kind of above-mentioned detection QS weld strength test-bed, described method Comprise the following steps:
The first step: selecting to use the lateral stability pipe of certain welding procedure, mode is installed as shown in Figure 2.Second step: square Pipe deadweight can produce the moment of torsion making lateral stability rod twisting, thus first needs to measure the moment of torsion that rectangular tube deadweight produces, this operation Can realize in large commercial CAD software.3rd step: surveyed data demarcated pull pressure sensor, outside making not apply The numerical value that during power, each display shows is the half of the torque value that rectangular tube produces because of deadweight.4th step: make direction pipe with certainly Weight FREE TORSION, and check whether display show value is calibration value.5th step: manual panel nut of twisting, observation display number Word changes.6th step: if two display display numerical value differences are relatively big, change the mode twisting panel nut, make two display numerical value Synchronize.7th step: when display numerical value reaches to specify moment of torsion, stop operation, checks whether lateral stability pipe weld seam ftractures.If Cracking, returns the first step.If not ftractureing, then carry out the 8th step.8th step: maintain and specify moment of torsion, stands 30min, if cracking, returns Returning the first step, if not ftractureing, then carrying out the 9th step.9th step: continue to increase moment of torsion, and whether Real Time Observation has crack to produce, Record produces torque value during crack.Tenth step: unclamp panel nut to initial position, off-test.
In addition to the implementation, this utility model also includes other embodiments, all employing equivalents or equivalence The technical scheme that substitute mode is formed, within all should falling into this utility model scope of the claims.
