Embodiment
This embodiment provides a kind of bolt welding strength detection device, and it can ensure, on the basis of bolt verticality, effectively to improve the detection efficiency of bolt welding intensity.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the bolt welding strength detection device that this embodiment provides, comprising: sleeve pipe 11, and the end of sleeve pipe 11 is provided with the trepanning 12 that bolt to be detected can be inserted in, and the end face 13 of trepanning is perpendicular with the axis of trepanning 12;
Support footing 14, be arranged at the outer peripheral face of trepanning 12.
So arrange, while adopting bolt welding strength detection device that this embodiment provides to carry out bolt welding intensity detection, only the trepanning of sleeve pipe 11 12 need be enclosed within to the periphery of bolt to be detected; Then pull sleeve pipe 11, now, sleeve pipe 11 is to support footing 14 as strong point formation lever, so that the easier run-off the straight distortion of bolt; Then oppositely pull sleeve pipe 11, bolt is set back; So repeatable operation is more than once or twice or twice, and observes bolt solder joint and have or not and come off, and testing process is convenient and swift, has effectively improved detection efficiency.
It should be noted that, the trepanning 12 that is arranged at sleeve pipe 11 can also can be blind hole for through hole, only need bolt to be inserted in completely, in addition, the internal diameter of trepanning 12 and the external diameter of bolt need to be clearance fit, so can, bolt being nested on the basis in trepanning 12 smoothly, ensure that the gap of bolt and trepanning 12 is less, to ensure deflection and the verticality of bolt.
In addition, it is emphasized that, the bolt welding strength detection device providing due to this embodiment, the end face 13 of its trepanning is perpendicular with the axis of trepanning 12, and in the time turning back sleeve pipe 11, the end face 13 of trepanning can be used as reference field, when the end face 13 of trepanning fits with the installed surface of bolt, can ensure that bolt and bolt installed surface are perpendicular state, so, ensure the verticality of bolt.
In sum, the bolt welding strength detection device that this embodiment provides, it can ensure, on the basis of bolt verticality, effectively to improve the detection efficiency of bolt welding intensity.
It should be noted that, when bolt and outdoor machine of air-conditioner chassis weld together, conventionally have multiple pedestals, Given this, in the preferred version of this embodiment, support footing 14 can be provided with multiple, and along the circumferential distribution of the outer peripheral face of trepanning 12.
It should be noted that, above-mentioned multiple support footing 14 is corresponding one by one with multiple pedestals, in the time detecting bolt welding intensity, can be using each support footing 14 all as a strong point, and pull repeatedly with the direction of each pedestal, whether come off in bolt deformation process to detect each pedestal, and then each pedestal of bolt is all detected, further ensured the reliability of bolt welding.
Such as, in the time that the pedestal of bolt has three, and angle between two pedestals of arbitrary neighborhood is while being 120 °, in this embodiment, just can be set to three by supporting footing 14, and three footings are uniformly distributed in the outer peripheral face of trepanning 12.Whether when detecting when weld strength, making three, to support footings 14 corresponding one by one with three pedestals, and backward each pedestal direction is pulled sleeve pipe 11 twice, and detect one by one three pedestals and have and come off.
In addition, in this embodiment, the two ends of sleeve pipe 11 can be equipped with trepanning 12, the diameter of these two trepannings 12 can be different, so, adopt a bolt welding strength detection device, can detect the bolt of two kinds of different-diameters, certainly, the diameter of two trepannings 12 also can equate.
In order to ensure, in the time that the pick-up unit that adopts this embodiment to provide carries out bolt welding intensity detection, to make bolt that enough deformation quantities occur, and there is unified deformation quantity.In another preferred version of this embodiment, the end face 13 of supporting surface 15 relative trepannings that supports footing 14 slopes inwardly, and the supporting surface 15 that supports footing 14, along the axle center of sleeve pipe 11 to peripheral direction, is drawn close to the middle xsect of close sleeve pipe 11 gradually.
So arrange, while pulling sleeve pipe 11, the supporting surface 15 that supports footing 14 is supported on the mounting plane of bolt, in the time that the supporting surface 15 of support footing 14 fits with the mounting plane of bolt, can not continue to pull sleeve pipe 11 again.Such as, support the supporting surface 15 of footing 14 and the end face 13 angle a of trepanning can be 10 °, in the time pulling the angle of sleeve pipe 11 and reach 10 °, the supporting surface 15 that supports footing 14 with the mounting plane laminating of bolt, sleeve pipe 11 can not be continued to pull.Certainly, support the supporting surface 15 of footing 14 and the end face 13 angle a of trepanning and also can be 13 °, 15 °, 18 ° or 20 ° etc.Like this, while detecting bolt welding intensity, can ensure that bolt produces consistent deflection at every turn, its examination criteria is consistent, both while having ensured detection weld strength, can there is enough deflections in bolt, also avoided bolt generation excessive deformation amount and destroyed the problem of welding quality.
As preferably, support the supporting surface 15 of footing 14 and the end face 13 of trepanning crossing.So arrange, owing to supporting, the supporting surface 15 of footing 14 and the end face 13 of trepanning are crossing, there is no tomography between the two, pull sleeve pipe 11, when bolt starts deformation occurs, can be subject to the supporting role of supporting surface 15, easy to operate.
In addition, in order to prevent that support footing 14 produces the problem of distortion when stressed, support footing 14 and can be set to plate-like structure, support the tangent plane of footing 14 perpendicular to the outer peripheral face of sleeve pipe 11, and support the outer peripheral face that be axially connected in sleeve pipe 11 of footing 14 along sleeve pipe 11.
So arrange, in the time that support footing 14 is stressed, the normal direction that supports footing 14 can be not stressed, ensured that support footing 14 can not produce distortion.And, so arrange, support 14 of footings and be subject to, along the axial component of sleeve pipe 11 with perpendicular to supporting the component of footing 14 with the joint face direction of sleeve pipe 11, can further avoid supporting footing 14 and produce the problem of distortion.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
