The assembly process has the advantages that the assembly process of the safety belt and the safety belt winder is improved; the assembly process of firstly connecting the safety belt onto the safety belt winder in a penetrating way and then sewing the end part of the safety belt is adopted; the problem of assembly difficulty of the safety belt and the safety belt winder in the prior art is solved; the work difficulty of workers is reduced; and the production efficiency is improved.
Description
Technical field
The invention belongs to auto parts and components production technology, particularly the assembly technology of a kind of safety strap and belt retractor.
Background technology
Automobile safety belting comprises ribbon coiler; ribbon coiler kind is more; wherein, the ribbon coiler with pretension function can be eliminated the slackness between ribbon and occupant, the relative motion amount between reduction occupant and car body well because of it, be studied obviously and widely the chest of occupant and the protective effect of belly in collision case.
In the production process of belt retractor of the prior art, all carry out a stitching after first the end of safety strap being bent, form a cover portion, then artificial guides cover portion passed on coiler, then at the through hole of the mandrel through coiler, fix finally by hold-down bars is carried out one through the two ends that cover portion is connected to the through hole of mandrel, there is following problem in this: due to the cover portion first formed in the stitching of safety strap, add the thickness of safety strap end, the through hole of guides and mandrel is rectangle, folding in order to ensure that safety strap can not be formed in the through hole of guides and mandrel, the width of through hole is generally slightly larger than the thickness of safety strap, and the different widths of the thickness in cover portion formed and through hole is little, certain interference is there is in both in fitting process, larger to the injury of the hand of workman in fitting process, also have impact on work task efficiency simultaneously, then have impact on the labor income of workman, finally cause the frequent substitutions in this post, also result in the lifting of enterprises using the labor cost.
Further, due to the compact conformation of coiler, be unfavorable for that hand is extend into coiler inside and operates safety strap by workman, cause work efficiency low.
Summary of the invention
For the deficiencies in the prior art, the assembly technology of the present invention to safety strap and belt retractor improves, and overcomes the problem that safety strap and belt retractor in prior art assemble difficulty.
The present invention is achieved through the following technical solutions:
The assembly technology of safety strap and belt retractor, is characterized in that comprising the following steps:
Step 1, belt retractor is fixed on auxiliary mould, makes the angle of the axis of the activity-oriented device of belt retractor and the axis of mandrel through hole in obtuse angle;
Step 2, by the end of safety strap successively through activity-oriented device and mandrel through hole;
Step 3, the end of safety strap is bent to form folding part;
Step 4, the end of folding part and safety strap to be sewed up, form a cross-under portion;
Step 5, locking rod to be penetrated in cross-under portion, and safety strap is drawn back, locking rod and mandrel through hole end are clamped.
The assembly technology of the present invention to safety strap and belt retractor improves, first, what the present invention adopted is the method for first wearing rear seam, reduce the difficulty that safety strap passes activity-oriented device and mandrel through hole on the one hand, be convenient to the cross-under that staff carries out safety strap and belt retractor, improve production efficiency, on the other hand, improve the working environment of workman, due to the end of the safety strap after stitching of the prior art and all can there is certain interference between activity-oriented device and mandrel through hole, this just needs workman to enforce safety strap, easily there is the collision between workman's finger position and belt retractor, cause the hand of workman injured, working environment and working strength larger, the present invention efficiently solves the problems referred to above.Secondly, the angle of the present invention to the axis of the axis of belt retractor and mandrel through hole limits, and adopts above-mentioned angle, after safety strap passes from activity-oriented device, under the influence of gravity, can enter smoothly in mandrel through hole, carry out craft without the need to personnel to assist, improve the efficiency of threading.
Mandrel in described step 1 is the mandrel after tensioning, and mandrel is formed fixing by bayonet lock and belt retractor housing, mandrel through hole is limited relative to belt retractor angle herein, be convenient to the location of the angle of the activity-oriented device in later stage, facilitate staff to carry out threading operation.
The end of described mandrel through hole is formed with the container cavity holding locking rod, and the end of container cavity extends on the mandrel at mandrel through hole two ends, locking mode between locking rod and mandrel through hole is limited herein, the container cavity arranged can prevent locking rod to be moved, and causes safety strap to be connected unbalanced problem with mandrel.
The width in described cross-under portion is 2-4cm, limits the width in cross-under portion herein, is conducive to the degree of utilization improving safety strap material, reduces feed stock cost.
The length of described locking rod is greater than the width of safety strap.
In sum, the present invention has following beneficial effect:
The assembly technology of the present invention to traditional safety strap and belt retractor improves, improve the assembly difficulty of safety strap and belt retractor, improve working environment and the mode of operation of workman, moreover, also improve the assembling speed of safety strap and belt retractor, improve production efficiency, meet the requirement of the output day by day increased.
