Description
Technical field
The present invention relates to the grip device that a kind of arc stud welding that is used for bonding bolt detects, specifically, relate to a kind of non-destructive of carrying out and decide the detection anchor clamps that moment of torsion detects stud welding intensity.
Background technology
The stud welding The Application of Technology is more extensive both at home and abroad, is mainly used in the welding of structural member, and mostly is the single face stud welding.
In the weld car production run, arc stud welding often has phenomenons such as rosin joint, puncture plate, if can not effectively detect its weld strength, will cause a large amount of arc stud welding substandard products to scrap, and brings economic loss.It is less to detect jig Design for arc stud welding at present, and the existing simpler and cruder arc stud welding detection method of using is divided two kinds of destructiveness and non-destructives.
The destructive detection: hammering or entangle double-screw bolt with simple and easy sleeve pipe ° does not come off double-screw bolt bending 〉=90 or tears parent, the requirement of nugget size conformance with standard.
Non-destructive detects: the simple and easy sleeve pipe that cut-off directly is slightly larger than double-screw bolt entangles double-screw bolt, about pull 5-6 time after, whether detection double-screw bolt root has crackle, flawless is qualified.
But there is following deficiency in above two kinds of detection methods:
Non-destructive Casing Detection:, can not detect by accurate quantification fully with the feel operation; If Overexertion easily makes the screw thread distortion, cause substandard product hidden danger;
The destructive detection scrapped part, and production cost improves; Can not 100% detection in time find substandard product simultaneously, can not effectively control product quality.
" being used for the coupling arrangement that arc stud welding detects " (application number: CN200720071699.6) that has only Shanghai Delivery Co., Ltd. Car Parts branch Co.,Ltd's application of applying for a patent of the detection anchor clamps of at present domestic arc stud welding.But it has its limitation, because it mainly is at planting the weldering bolt.Because the bolt on the automobile is of a great variety, different bolts needs different anchor clamps to cooperate, special bonding bolt is extensively used on automobile, its effect and texture ratio are more special, need design its anchor clamps separately to the detection of bonding bolt, satisfying follow-up engine request, but be blank at present for the detection method of the arc stud welding of bonding bolt.
Summary of the invention
Technical matters to be solved by this invention provides a kind of non-destructive of can carrying out and decides the detection anchor clamps that arc stud welding detects that are used for that moment of torsion detects bonding bolt intensity, detects defectives such as the accuracy of detection that exists is not high, cost of idleness, destructible screw thread to overcome existing arc stud welding.
The technical solution adopted for the present invention to solve the technical problems provides a kind of detection anchor clamps of bonding bolt stud welding, comprise matrix, be fixed on the moment of torsion portion that applies of matrix upper end, the ring-like locking device of semicircle, locking pin and sleeve, matrix is a column type, the bottom is set to the semi-circular structure of hollow, the semi-circular structural base of hollow is provided with the matrix boss, the semi-circular structure switching of the hollow of ring-like locking device of semicircle and matrix underpart, the ring-like locking device of semicircle bottom is provided with the locking device boss, jacket casing is on matrix, the sleeve wall of sleeve is provided with the helix groove of two symmetries, matrix is provided with a through hole, the locking pin passes two helix grooves of sleeve and the through hole of matrix, when matrix rotated, the locking pin moved in the groove of helix groove.
Also be provided with on the sleeve wall of sleeve; The vertical slot of two symmetries, the top of two vertical slots communicates with the bottom of each self-corresponding helix groove.
Also be provided with the level trough of two symmetries on the sleeve wall of sleeve, the left end of two level troughs communicates with the bottom of each self-corresponding vertical slot.
Applying moment of torsion portion is pitman.
Pitman is the hexagonal pitman.
The semi-circular structure of hollow of ring-like locking device of semicircle and matrix underpart is transferred by pivot pin.
The aperture, inside that locking device and matrix underpart form is consistent with bonding bolt size to be measured.
The detection anchor clamps of this bonding bolt stud welding cooperate the torsion distance, can realize that non-destructive decide the intensity of moment of torsion detection bonding bolt stud welding, have following advantage: needn't destroy part during detection, reduce production costs; Can satisfy 100% total piece test, strengthen the arc stud welding quality control; Improve the accuracy of detection of welding for grounding screw at present; Decide the arc stud welding of moment of torsion safety detection, guarantee that double-screw bolt is not destroyed, really realize nondestructive test.

Embodiment
As shown in Figure 1, the detection anchor clamps of bonding bolt stud welding of the present invention comprise sleeve 1, matrix 2, pitman 3, locking pin 4, hexagonal nut 5, pivot pin 6, packing ring 7 and the ring-like locking device 8 of semicircle.
Pitman 3 is the hexagonal pitman, is fixedly connected on matrix 2 upper ends, is used to apply moment of torsion.Matrix 2 is a column type, and the bottom is set to the semi-circular structure of hollow, and locking device 8 is by pivot pin 6, nut 5 and the packing ring 7 switchings semi-circular structure of the hollow place in matrix 2 bottoms.The aperture, inside that locking device 8 and matrix 2 bottoms form is consistent with the size of bonding bolt 14 to be measured.Half round ring boss 9 is arranged at matrix 2 bottoms, ring groove 15 positions that in assembling process, are embedded into the bottom of bonding bolt, when closing locking device 8, second half round ring boss 10 of locking device 8 bottoms is embedded into ring groove 15 positions of the bottom of bonding bolt, thereby the vertical direction of realization bonding bolt and detection anchor clamps is fixing.
The sleeve wall of sleeve 1 is provided with the helix groove 11 by two symmetries, the U-lag of two symmetries of the vertical slot 12 of two symmetries and two symmetrical level trough 13 formation, matrix 2 is provided with a through hole, during installation, sleeve 1 is enclosed within on the matrix 2, matrix 2 is concentric with sleeve 1, and locking pin 4 passes two U-lags of sleeve 1 and the through hole of matrix 2, the two end supports of locking pin 4 is on the U-lag of sleeve wall both sides, locking pin 4 can move along the U type, when dial torque wrench drives matrix 2 rotations, pin is moved in the groove of helix, thereby make its matrix 2 that the trend of (or downwards) motion be arranged upwards, realize that just torque axis turns to the vertical force that acts on the weld bolt.
As shown in Figure 8, arc stud welding provided by the invention detects anchor clamps, and it is as follows that it detects step:
Step a: the incipient stage, sleeve 1 is inserted in the matrix 2, insert locking pin 4, and sleeve 1 is placed on the top of matrix 2, locking pin 4 is positioned at the low order end of level trough 13, and the ring-like locking device 8 of semicircle is opened, and will detect anchor clamps and be placed on the bonding bolt place;
Step b: close stage, the ring-like locking device 8 of the semicircle that closes along level trough 13 rotations, makes locking pin 4 be positioned at the high order end of level trough 13 in sleeve 1, then sleeve 1 is put down along vertical slot 12, locks the top that pin 4 is positioned at vertical slot 12 this moment;
Step c: revolving process, by direction as shown turnbarrel 1, sleeve 1 continues to move downward, and the bottom of sleeve 1 contacts with bonding bolt installed surface 16, lock the middle part that pin 4 is positioned at helix groove 11 this moment, and earth stud, sleeve, matrix vertical direction are fixed;
Steps d: drawing stage, adopt suitable dial torque wrench to apply moment of torsion by direction as shown at pitman 3 places, locking pin 4 will have the trend that moves upward along helix groove 11, realize that torque axis turns to the vertical force that acts on the weld bolt, carry out non-destructive and detect.
