Abstract
The invention discloses a method for eliminating clamping jitter during welding of sheet metal parts. The method includes the following steps that (1) the two welded parts are clamped through clamps; (2) a sensor senses whether the parts are clamped in place or not; and (3) specific welding is conducted. A time period is delayed after the clamping action of the clamps in the step (1) is finished, then the sensor performs sensing, and jitter generated by the clamps is completely eliminated within the time period. By means of time delay after clamping, sensing is performed after the jitter is completely eliminated, therefore the sensed thickness can represent a true value, and misjudgment can be avoided. Accordingly, the welding accuracy is improved, and the machining level and the machining efficiency are improved. The method for eliminating the clamping jitter during welding of the sheet metal parts is easier to implement and more economical, and the welding process only needs to be slightly changed.
Description
Technical field
The present invention relates to the improvement of the welding of sheet metal parts method, eliminate the method for clamping shake when being specifically related to a kind of the welding of sheet metal parts, belong to sheet metal component processing technique field.
Background technology
The processing that automobile production relates to many sheet metal components with weld.Because automobile metal plate work structure is numerous, modeling characteristic is different, and therefore different sheet metal components has different features and technical requirement when processing or welding.In automobile metal plate work processing, a procedure is had to be automobile parcel shelf assembly and the welding of rear safety belt fixed head, when welding, first need by the fixture on welding equipment, automobile parcel shelf assembly and rear safety belt fixed head to be clamped together, and then by inductor, detection judgement is carried out to the object thickness after clamping, when the thickness that inductor senses is for both thickness sums, show that both have clamped to put in place, now can weld, otherwise think that part does not put in place, can not weld.Because fixture is when clamping both, because the unexpected effect of power, clamping object can be caused to produce certain shake, particularly the very large product thin again of this area of automobile parcel shelf assembly, shakes more obvious; The appearance of this shake can make inductor produce erroneous judgement, and cause the thickness induced to be greater than actual (real) thickness, its consequence is: if two object clampings to be welded put in place, induction thickness may be made much larger than actual (real) thickness, cause system to judge disorderly; If do not have clamping to put in place (because rear safety belt fixed head is very little relative to automobile parcel shelf assembly volume, and self is thinner, rear safety belt fixed head does not clamp this situation that puts in place and frequently occurs in practice), because the thickness that shake can make inductor induce is just in time both thickness sums (or in scopes of accreditation), now system can send the erroneous judgement clamping and put in place, thus welding job wrong after carrying out.Under other are caught up with and state similar welding occasion, same exist the problems referred to above brought because of clamping shake, and this occasion is mainly in the welding of sheet metal component, because a lot of sheet metal component is large-area steel plate, easily produces shake when clamping.In order to solve clamping jitter problem, prior art has carried out various improvement to fixture (clamp head), not only complex structure, and effect is very unobvious.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is: how to provide a kind of method eliminating clamping shake during the welding of sheet metal parts, the method can solve because the shake of clamping moment makes inductor produce the erroneous judgement clamping and put in place, thus improves level of processing and efficiency.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
The method of clamping shake is eliminated during the welding of sheet metal parts, two parts to be welded are sheet metal component, and wherein one piece of sheet metal component area is less than 1/20th of another block sheet metal component area, and less sheet metal component length and width are all no more than 10mm, comprising the steps, 1) two parts to be welded pass through holder; 2) by induction thickness, inductor judges whether that clamping puts in place; 3) finally specifically weld; It is characterized in that: the 1st) postpone a time period after the release of step holder, then responded to by inductor, this time period recovers completely for the shake making fixture produce.
The described time period is 0.8-1.5 second, and actual is 1 second.This time delay, had both ensured that the shake produced can be eliminated completely, did not affect inductor induction, can reduce again time delay to the impact of producing as far as possible.
The present invention is by the time delay after clamping, and respond to after shake recovers completely, the thickness induced so just can represent actual value again, can not cause erroneous judgement, thus improves the accuracy of welding, improves level of processing and efficiency.
Evade shake to the improvement of fixture compared to existing technology, this method realizes simpler, economical, only needs to do very little change to welding procedure.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail.
Eliminate the method for clamping shake during the welding of sheet metal parts of the present invention, comprise the steps, 1) two soldering parts are clamped by fixture; 2) whether inductor (passes through thickness) again and responds to two parts and clamp and put in place; 3) if induction puts in place, more specifically weld, otherwise think that part does not put in place, do not weld.In order to eliminate clamping shake, the present invention is the 1st) postpone a time period after the release of step holder, after shake is eliminated completely, then responded to by inductor, namely this time period can ensure that the shake that fixture produces recovers completely.
This method is only for particular condition, and namely two parts to be welded are sheet metal component, and wherein one piece of sheet metal component area is less than 1/20th of another block sheet metal component area, and less sheet metal component length and width are all no more than 10mm.Under such particular condition, easily there is clamping shake on the one hand, also easily occur the situation that clamping is not in place on the other hand, so just there is inductor erroneous judgement and invalid welding.
The described time period is 0.8-1.5 second, is actually set to 1 second.The consideration of this time delay, had both ensured that the shake produced can be eliminated completely, did not affect inductor induction, can reduce again time delay to the impact of producing as far as possible.
The present invention is by the time delay after clamping, and respond to after shake recovers completely, the thickness induced so just can represent actual value again, can not cause erroneous judgement, thus improves the accuracy of welding, improves level of processing and efficiency.
Evade shake to the improvement of fixture compared to existing technology, this method realizes simpler, economical, only needs to do very little change to welding procedure.
In implementation process, also can be clamped two soldering parts by multiple spot (as 2-3 point), to eliminate shake as far as possible, then coordinate time delay, then can reduce time delay.Such as, the time delay that an independent bite needs is 1 second, so by 2-3 bite, postpones 0.2-0.5 and just can eliminate shake completely second.
Below be only the preferred embodiment of the present invention; need point out be; for those skilled in the art under the prerequisite not departing from the technical program, can also make some distortion and improvement, the technical scheme of above-mentioned distortion and improvement should be considered as falling into the scope that this application claims protection equally.
