The laser butt-welding device for the automobile component has the benefits as follows: the laser butt-welding device can be easily integrated into the production line to carry out large-scale butt-welding of steel plates; and pins and the clamping element which can move vertically are used for fixing the steel plates and reducing welding seams, so as to solve the problems of unreliable system running and easy damage caused by adopting only the clamping element for fixation and improve the welding quality.
Description
Technical field
The utility model relates to the laser assembly solder field, relates in particular to a kind of automobile spare laser opposite soldering device.
Background technology
The laser assembly solder technology is widely used in automobile manufacturing field, especially vehicle body design and manufacturing.Laser assembly solder plate be steel plate with two or many different-thickness or unlike material through laser to being welded into a block plate, carry out whole punch forming then.For guaranteeing welding quality, in welding process, need with each steel plate to be welded of clamps.Because laser assembly solder requires very strictness to the fit-up gap of two fishplate bars to be welded, and produces thermal stress in the process of laser assembly solder, makes that the welding gap is increasing, influences welding quality.
Chinese patent CN1346304A discloses a kind of laser welding system; This system is in order to overcome the fit-up gap problem of unstable of two fishplate bars to be welded; Parts fixation steel plate upper surfaces such as clamping element, upper bracket, cylinder, airbag have been adopted; Reduce the joint clearance as much as possible, but the mechanism of action relative complex.Because clamping element presents the clip shape, less with the part lifting surface area that steel plate directly contacts, so clamping element damages easily, also damage easily of airbag has in addition influenced the reliability of gap reduction means.When the gap reduction means breaks down, can not monitor in real time, possibly cause the waste of sheet stock.In addition, this system has adopted the lead frame of fixed-site to place steel plate, is unfavorable for being integrated in the production line, is unfavorable for that the butt welding of extensive steel plate is handled.
The utility model content
The purpose of the utility model is to overcome the problems referred to above; A kind of novel automobile spare laser opposite soldering device is provided, and the weld seam size between this device monitoring butt welding in real time steel plate clamps steel plate to reduce the joint clearance as far as possible; Be fit to the extensive butt welding of steel plate, improve the quality of laser assembly solder.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is: automobile spare laser opposite soldering device, it is characterized in that, and comprising: the roller-way of carrying and place steel plate; Be installed on to be used for fixing above the roller-way and place steel plate at least one clamping element on roller-way; Be used for welding the laser welding system of two steel plates in the position that two steel plates weld mutually; Be positioned at the upper bracket and the cylinder of clamping element top, can compress clamping element during cylinder moving, make clamping element leave steel plate; Airbag between upper bracket and clamping element compresses steel plate thereby behind the airbag inflation clamping element is pivoted.
Aforesaid automobile spare laser opposite soldering device, described laser welding system comprises welding tip and half-reflecting mirror.
Aforesaid automobile spare laser opposite soldering device also comprises the pin that is positioned at the roller-way below, and when steel plate was in correct welding position, cylinder drives to move on the pin fixed steel plate.
Aforesaid automobile spare laser opposite soldering device, the other sensor that is provided with of the position while welding of described two steel plates.
The beneficial effect of the utility model is: two transmission roller channels are set carry two blocks of steel plates to be welded respectively, compare with fixed lead frame, be integrated into the butt welding of carrying out extensive steel plate in the production line easily; Adopt pin moving up and down and clamping element dual mode fixation steel plate and reduce the welding slit; Overcome unreliable, the flimsy problem of system's operation that only adopts clamping element fixedly to bring; Weld seam size between the sensor in real time monitoring butt welding steel plate; Also guaranteed the operation stability of the utility model, can practice thrift steel and improve the welding quality.
