Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, the detection frock of particularly arc stud welding weld strength.
Background technology
Arc stud welding is used very general in automobile industry, in order to ensure the fixing that welds between double-screw bolt and the auto panel, need the weld strength of double-screw bolt be detected.At present, general way is to adopt the mode of knocking, and makes about crooked 15 degree of double-screw bolt, again according to having free from flaw to judge whether weld strength meets the requirements around the range estimation double-screw bolt.On the one hand means are coarse, standardization is poor, waste time and energy with upper type; On the other hand, neither one quantitative criteria, testing result were both inaccurate, and be also unreliable.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of detection arc stud welding weld strength accurately and reliably to detect frock.
Technical scheme of the present invention is following: a kind of arc stud welding weld strength detects frock; Comprise that connection guide pole (1), upper bracket (2), undersetting (3), thimble (4), load bearing seat (5), supporting guide pole (6), rest pad (7), bolt (8), nut sleeve (9) are connected guide pole (1) with (10) two of supporting sleeves and are symmetrical set; The fixing upper bracket (2) in the upper end of two connection guide poles (1); The lower end of two connection guide poles (1) is undersetting (3) fixedly; The middle part of said upper bracket (2) is equipped with thimble (4) from top to bottom; In the below of thimble (4) load bearing seat (5) is set, this load bearing seat (5) between upper and lower bearing, and load bearing seat (5) be connected guide pole (1) and be slidingly matched; In said undersetting (3), be equipped with two supporting guide poles (6); Supporting guide pole (6) is slidingly matched with undersetting (3); Each upper end and load bearing seat (5) that supports guide pole (6) fixes; In the below of said undersetting (3) rest pad (7) is set, two bolts (8) pass rest pad (7) from lower to upper and stretch in the corresponding supporting guide pole (6), and rest pad (7) and supporting guide pole (6) are fixed together; Between two bolts (8), be provided with nut sleeve (9); Upper end of this nut sleeve (9) and undersetting (3) fix, and the lower end of nut sleeve (9) is stretched in the supporting sleeve (10), and this supporting sleeve (10) is fixed in the central authorities of rest pad (7) bottom.
When the present invention is used to detect the arc stud welding weld strength, earlier nut sleeve is screwed in the double-screw bolt to be detected, make the mother metal of double-screw bolt be positioned at the below of supporting sleeve, and the bottom surface of the upper surface of mother metal and supporting sleeve fits; Then pressure detector is placed on the load bearing seat, makes pressure detector over against thimble; Rotate thimble then, the relative upper bracket of thimble is moved down, the lower end of thimble is stretched in the pressure detector; And thimble passes through pressure detector to the lower compression load bearing seat; Load bearing seat is moved downward together with supporting guide pole, bolt, rest pad and supporting sleeve, and supporting sleeve is to the mother metal of lower compression double-screw bolt, and this moment, double-screw bolt was locked by nut sleeve; Along with thimble continue move down, double-screw bolt and mother metal finally come off.Diameter through inspection weldering nuclear and pressure detector is read when coming off force value judge whether weld strength is qualified at last.This shows that above technical scheme is not only simple to operate, time saving and energy saving, and testing result is through quantize embodying, not only accurately but also reliable.
For simplified structure, be convenient to assembling, and make upper bracket and to be connected between the guide pole connection firm, said upper bracket (2) is sleeved on the upper end of two connection guide poles (1), and is spacing up and down by set nut (11).
The lower end of said thimble (4) is conical, has through hole in the upper end of thimble (4), is equipped with handle (12) in this through hole, can rotate thimble through operating grip, and is convenient and labor-saving; The taper hole of the conical structure of thimble lower end and pressure detector top central authorities adapts, and both engage closely when work, can prevent effectively that pressure detector from shaking in surface level, guaranteed the accuracy of testing result.
Install, strengthen the fixing of connection for ease; Said supporting guide pole (6) is up-small and down-big two-part step; The step surface of supporting guide pole (6) and the bottom surface of load bearing seat (5) fit, and the epimere of supporting guide pole (6) stretches in the load bearing seat (5) both threaded engagement.
In order to make structure compact more and help assembling, the middle part of undersetting (3) is stretched in the upper end of said nut sleeve (9), both threaded engagement, and the upper surface of nut sleeve (9) is concordant with the end face of undersetting (3).
Beneficial effect: the present invention is simple in structure, and is easy and simple to handle, quick, and testing result can be used for the destructive test or the non-destructive testing (NDT) of stud welding intensity accurately and reliably, and usable range is wide, highly versatile.
