Description

Technical Field

[0001] The utility model belongs to the technical field of automobile sunshade processing equipment, and particularly relates to a material pulling device for sunshade. Background Art

[0002] Every process in the production of automotive sunshades requires inspection. Inspections of the entire sunshade assembly include flatness, verticality, appearance, dimensions, and strength. These inspections require the sunshade to be extended, making a pull mechanism essential. Our car sunroofs are all curved, and the sunshade's trajectory is also curved, requiring the pull mechanism to have a relatively free path. The tension must be moderate: too loose, and the sunshade will easily slip out; too tight, and the sunshade will wrinkle. To address these challenges, we've developed a highly stable pull mechanism for sunshades. Summary of the Invention

[0052] The bushings 16 are fixed to corresponding positions of the lower guide mounting plate 21;

[0053] The butterfly knobs 19 are connected to the lower connecting plate 20 through the lower guide mounting plate 21;

[0054] The guide shaft groups 17 pass through the bushings 16 respectively, wherein a spring is provided on the outside of the guide shaft groups 17;

[0055] The pressing block 18 is fixed to the shaft end of the guide shaft assembly 17;

[0056] The locking sleeves 15 are respectively inserted into the other side of the guide shaft assembly 17;

[0057] The guide shaft connecting plate 14 is fixed to the other side shaft end of the guide shaft assembly 17 .

[0058] The upper pulling assembly 2 includes: a guide shaft connecting plate 14 , a locking sleeve 15 , a bushing 16 , a guide shaft assembly 17 , a pressure block 18 , an upper guide mounting plate 22 , an upper connecting plate 23 , a sensor bracket 24 , a sensor 25 , and a quick caliper 26 .

[0059] The bushings 16 are fixed to corresponding positions of the upper guide mounting plate 22;

[0060] The guide shaft groups 17 pass through the bushings 16 respectively;

[0061] The locking sleeves 15 are respectively inserted into the guide shaft groups 17;

After the width of the sunshade 27 changes, the relative distance between the left and right pressure blocks 18 in the pulling device 28 can also be changed by the indexing pin 12 to achieve rapid locking.
