Technical field
This utility model belongs to automobile production field, refers in particular to fully automatic feeding and the full-automatic extractor of finished product of a kind of part when fixed spot welder part spot welding nut.
Background technology
In automobile production, commonly used fixing point welder nut, generally use artificial hand-held part, hole, the location of the nut on part is utilized to position on the positioning of electrode pin of fixing point welding machine, nut conveyor conveying nut is used to carry out the mode welded, its job step is relatively complicated, easily occurs that solder skip, running hours add potential safety hazard.Meanwhile, inefficiency, personnel labor intensity is big, and welding quality is unstable.
Summary of the invention
This utility model provides a kind of fixing point welding machine Full-automatic feeding device, and to solve in the way of existing nut conveyor conveying nut welds, inefficiency, personnel labor intensity is big, the problem that welding quality is unstable.
nullThe technical solution of the utility model is: side location-plate、Guide rail and send part cylinder use screw be fixed on base plate,Step is had above the location-plate of side,Kicker is connected with the piston sending part cylinder,The bottom of kicker is arranged on the slideway of guide rail,And can reciprocatingly slide along slideway,Upper cover plate one and upper cover plate two use screw to be fixed on the location-plate of side,Photoelectric induction device is arranged on upper cover plate one,Slideway and lift cylinder are arranged on the top of upper cover plate one,The piston of lift cylinder is connected with lifter,Connected by guide blot and spring between upper cover plate one and lifter,Lifter can slide along guide blot,Connecting plate uses screw to be arranged on the lower end of side location-plate,Rise part pin top to be fixed under lifter,Rise part pin bottom and inlay strong magnets,Riser uses screw to be arranged on the both sides of upper cover plate one,Bullet ejector pin it is bumped in riser.
The utility model has the advantage of: novel structure, this utility model is arranged on the workbench of fixing point welding machine, fixing point welding machine and nut conveyor is coordinated to use, it is achieved the automatic transport of part, location, nut-welding, and the automatically exiting from of finished product, the non-cutting time of Product jointing can be shortened, improve work efficiency and utilization rate of equipment and installations, alleviate the labor intensity of personnel, reduce manufacturing cost, Improving The Quality of Products.

Detailed description of the invention
nullSide location-plate 11、Guide rail 12 and send part cylinder 16 to use screw to be fixed on base plate 15,Step is had above side location-plate 11,Kicker 13 is connected with the piston sending part cylinder 16,The bottom of kicker 13 is arranged on the slideway 1 of guide rail,And can reciprocatingly slide along slideway 1,Upper cover plate 1 and upper cover plate 2 14 use screw to be fixed on side location-plate 11,Photoelectric induction device 17 is arranged on upper cover plate 1,Slideway 1 and lift cylinder 10 are arranged on the top of upper cover plate 1,The piston of lift cylinder 10 is connected with lifter 2,Connected by guide blot 3 and spring 4 between upper cover plate 1 and lifter 2,Lifter 2 can slide along guide blot 3,Connecting plate 9 uses screw to be arranged on the lower end of side location-plate 11,Rise part pin 5 top and be fixed on lifter 2 times,Rise part pin 5 bottom and inlay strong magnets,Riser 6 uses screw to be arranged on the both sides of upper cover plate 1,Bullet ejector pin 7 it is bumped in riser 6.
The working method of this pay-off is: base plate uses screw to be arranged on the correct position of fixing point welding-machine operation table, after neat for multiple placing parts, disposably load from slideway, part automatically moves down because of action of gravity and is automatically positioned along slideway side, slideway indoor design has location error prevention device, avoid because wrongly installed part causes product rejection, limited location step above the location-plate of side, it is ensured that have 1 part to can be placed on step;The piston sending part cylinder ejects forward, drive kicker along guide rail forward slip to initial alignment region, and by the utilizing powerful magnet for adsorption on liter part pin, complete the initial alignment of part, photoelectric induction device is used for whether detecting part by utilizing powerful magnet for adsorption, avoid occurring just to position inefficacy, result in defective work;After photoelectric induction device senses location at the beginning of part, output signal, the piston of lift cylinder moves downward, drive lifter and rise part pin slide downward, part is pressed onto on the bottom electrode of fixing point welding machine, and the alignment pin of bottom electrode, through the hole, nut location of part, completes being accurately positioned of part;The nut conveyor conveying nut of fixing point welding machine, on part, is positioned through nut centre bore by positioning of electrode pin, and the upper spot welding head of fixing point welding machine falls, and contacts nut, welds;Sending part cylinder piston backhaul simultaneously, drive kicker to return to rear position, next part is dropped on the limited step of location-plate automatically by action of gravity;After having welded, lift cylinder piston return, plays ejector pin by finished parts jack-up, the utilizing powerful magnet for adsorption finished parts of liter part pin lower end, returning initial position location under the drive of lift cylinder piston, photoelectric induction device detects finished product again whether by utilizing powerful magnet for adsorption simultaneously;Photoelectric induction device senses finished product, output signal, send the piston of part cylinder again to eject, and drives kicker that next one part is transported to initial alignment region, completes the initial alignment of this part.The product piece that welding is completed by this part simultaneously ejects this device, with equipment outside chute be slipped to lower section finished product box in, complete welding, send part process.
Pay-off uses PLC to automatically control, and couples simultaneously, controls fixing point welding machine, nut conveyor and photoelectric induction device.After start button, by programme-control, finishing device and fixing point welding machine, each action of nut conveyor, it is achieved the Full-automatic welding of product.
