The utility model provides a weld joint tracking device comprising a mounting frame, an angle adjusting plate, a tracking cylinder, a tracking head, a tracking wheel, a tracking head planker, a first spring arranged between the tracking head and the tracking head planker, and a second spring arranged between the mounting frame and the tracking cylinder, wherein, the tracking cylinder is connected with the tracking head, the tracking head drives the tracking wheel, and the angle adjusting plate is connected with the tracking cylinder and the mounting frame. The weld joint tracking device adopts automatic welding instead of manual welding, can always maintain right parameters in the angle of a welding gun, the front end of a welding wire, the center distance of weld joints, and other respects, thereby ensuring favorable quadrant elevation weld joint forming.

Description

A kind of weld tracker
Technical field
The utility model relates to a kind of tracking means, relates in particular to a kind of tracking means that is used for elevation angle straight weld.
Background technology
All the time, in the manufacturing technology of the relevant C70A type of whole railway freight-car manufacturing open-top car, headwall and end carriage group are that the welding of 2700 millimeters elevation angle weld seam is to be accomplished by manual overhead welding mode always to the length that forms after accomplishing.Its concrete grammar is; The open-top car car body that at first will organize accomplishing is placed horizontally on the stand of welding post, uses the CO2 gas shielded arc welding to carry out manual welding with the mode of overhead welding by the electric welding operative employee then.Good in order to guarantee elevation angle appearance of weld, the electric welding operative employee at first should adjust to suitable welding current, voltage according to technological requirement.Make the vertical plane at welding gun and weld seam place become 40 °-50 ° angle then and remain the welding wire front end with the pitch of weld from being 2 millimeter, and it is laterally mobile uniformly when welding is carried out, in arcing point to the interval of receiving acnode of weld seam, to carry out speed as much as possible.In whole railway freight-car manufacturing; The welding of these two elevation angle weld seams of C70A type open-top car headwall and end carriage is to be accomplished with the mode of manual overhead welding by the electric welding operative employee always; Because manual overhead welding welding is very high to electric welder's technical merit requirement, and welding efficiency is low, labour intensity is big.So the welding quality of this weld seam is extremely unstable, and the car load presentation quality is constituted influence.
The utility model content
In order to solve existing technical problem in the background technology; The utility model provides a kind of weld tracker; Replace artificial welding with automatic welding; Can remain correct parameter in each side such as welding gun angle, welding wire front end and the pitch of weld leave, thereby guarantee that elevation angle appearance of weld is good.
The technical solution of the utility model is: a kind of weld tracker, and its special character is: said weld tracker comprises mounting bracket, angle adjustment plate, tracking cylinder, follower head, tracking wheel, follower head planker, is arranged on first spring between follower head and the follower head planker and is arranged on mounting bracket and follows the tracks of second spring between the cylinder; Said tracking cylinder connection tracking head, said follower head drives tracking wheel, and said angle adjustment plate is connected with mounting bracket with the tracking cylinder.
Be provided with the line slideway slide block between above-mentioned follower head and the tracking cylinder, said follower head is arranged on the line slideway slide block.
Above-mentioned weld tracker also comprises rotating shaft, and said mounting bracket, tracking cylinder all are connected with rotating shaft; Said angle adjustment plate slides up and down along mounting bracket, and the tracking cylinder is rotated around the axis.
Above-mentioned follower head is provided with welding gun adjuster and tracking wheel.
On the above-mentioned welding gun adjuster welding gun is set, said welding gun can be realized being connected with rotating shaft through with being connected of being connected of being connected of welding gun adjuster, welding gun adjuster and follower head, follower head and follower head planker, follower head planker and follow the tracks of being connected of cylinder.
The weld tracker of the utility model can remain correct parameter in each side such as welding gun angle, welding wire front end and the pitch of weld leave through mechanical structure; Thereby guarantee that elevation angle appearance of weld is good; System accomplishes a series of activities such as tracking and location automatically, makes welding quality break away from the dependence to electric welding operative employee technical merit and other individual factors.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The specific embodiment
Referring to Fig. 1, the weld tracker of the utility model adopts the mechanical type tracking means, and the mechanical type tracking means links to each other with mounting bracket 21 through rotating shaft 20 and 20 rotations around the shaft of mechanical type tracking means.When making progress slip angle adjustable plate 22, the initial angle of mechanical type tracking means and horizontal plane increases; When downward slip angle adjustable plate 22, the initial angle of mechanical type tracking means and horizontal plane reduces.Can control the elemental height of tracking wheel 27 and initial outreach through regulating mechanical type tracking means and the size of the initial angle of horizontal plane.Follow the tracks of cylinder 23 and link to each other, stretch out together when following the tracks of line slideway slide block 25, the follower head 26 that can drive follower head planker 24 simultaneously when cylinder 23 stretches out and upward install with follower head planker 24.Follower head 26 links to each other with follower head planker 24 through line slideway slide block 25, and tracking wheel 27, welding gun 28, welding gun adjuster 29 are installed on follower head 26.First spring 210 is installed between follower head planker 24 and follower head 26; Following the tracks of parts such as second spring 211 is installed between cylinder 23 and the mounting bracket 21.
In welding process, at first make weld tracker run to weld seam setpoint distance place apart from the elevation angle.To follow the tracks of cylinder 23 then stretches out.When tracking cylinder 23 stretched out, follower head planker 24 and the follower head of upward installing 26 thereof can stretch out together, and the tracking wheel 27 that is installed on the follower head 26 also stretches out with welding gun 28 simultaneously.Owing to follow the tracks of cylinder 23 outreach greater than the distance between tracking wheel 27 and the workpiece, the vertical surface that tracking wheel 27 has been run into workpiece when tracking cylinder 23 does not also stretch out fully.Because tracking wheel 27 receives the active force of workpiece, weld tracker 20 rotates counterclockwise around the shaft, and second spring 211 stretches and makes tracking wheel 27 be adjacent to surface of the work.Following the tracks of cylinder 23 promotion tracking wheels 27 continues to slide along surface of the work; When tracking wheel 27 outer rims arrive at elevation angle position while welding; Elevation angle weld seam radially applies reaction force to tracking wheel 27 along tracking wheel, and this reaction force affacts on the follower head 26 through tracking wheel 27 and makes 210 precommpression of first spring.When the automatic soldering device of the utility model welds when moving along X-direction, tracking wheel 27 is close to surface of the work all the time and is propped up weld seam under the effect of first spring 210 and second spring 211.When weld seam when Y axle or Z-direction have skew; First spring 210 carries out corresponding compression automatically or loosens; Make follower head 26 withdrawals or ejection, thereby in time compensated the side-play amount of Y axle or Z-direction, guaranteed that the welding wire front end of welding gun 28 and weld seam center remain constant distance.
