Description
Technical Field
The invention belongs to the field of cable production and processing, and particularly relates to an metal tube welding correction system.
Background
The welding needle of the welding machine needs to continuously weld right above a closed gap of a metal strip, so that the quality of the welding seam can be ensured, and if the position of the gap deviates from that of the welding needle, the welding needle cannot effectively weld the gap, so that 'partial arc' is caused, and the quality of the welding seam cannot be ensured.
In the production process, due to the existence of other factors such as mechanical vibration and uneven quality of metal strips, a gap formed after a metal strip is folded can generate left-right deviation relative to a welding needle, the welding needle cannot be guaranteed to be located right above the gap all the time, the quality of the welding seam is problematic, and due to the objective existence of the above uncertain factors, when the welding gun is started, production personnel need to pay close attention to the quality of the welding seam all the time, the position of the welding needle of the welding gun is manually adjusted according to the condition of the welding seam, the welding needle is controlled through a manual button to control a positioning motor of the welding needle, the welding needle is moved left and right, and. If the quality of the metal strip fluctuates frequently, manual repair welding is needed for many times, even shutdown repair welding is needed, factors influencing the uncertain quality of products are increased, the labor intensity and the operation difficulty of production personnel are increased, harmful factors such as strong light, harmful rays, excessive ozone and the like are generated by argon arc welding, and even if the production personnel are equipped with protective measures, the production personnel still can cause damage to human bodies under long-term frequent contact.

Detailed Description
The invention is further described with reference to the following figures:
as shown in FIG. 1, kinds of partial arc correction systems comprise a correction assembly 10, wherein a welding gun 1 is arranged on the correction assembly 10, a welding needle 11 is arranged at the lower end of the welding gun 1, and the correction assembly 10 is arranged on a bracket;
the welding gun comprises a welding gun 1, a camera 2, a correction assembly 10, a welding gun 1 and a connecting line , wherein the welding gun 1 is fixedly connected with the camera 2, the camera 2 is provided with an identification base point 21, the identification base point 21 is fixed on the camera 2, the correction assembly 10 can drive the welding gun 1 to move, the moving direction of the welding gun 1 is perpendicular to the connecting line between the welding gun 1 and the identification base point 21, and the connecting line is generally a connecting line of shaft axes as a reference.
The camera 2 and the correction component 10 are both electrically connected with a central controller.
When the metal pipe is welded, the identification base point 21 tracks the welding seam, when the identification base point 21 of the camera 2 detects that the position of the welding seam changes, a signal is transmitted to the central controller, and then the central controller transmits a signal to the correction assembly 10 to drive the welding gun 1 to move, so that the camera 2 on the welding gun 1 is driven to move, and the identification base point 21 is overlapped with the welding seam again.
Meanwhile, the correction assembly 10 is used for driving the welding gun 1 to move, and all structures capable of achieving the function can be adopted, for example, the welding gun 1 can be driven to horizontally move through an air cylinder arranged perpendicular to the welding gun 1, and the welding gun 1 and the camera 2 are relatively small in horizontal distance, and the two welding guns can be synchronously performed aiming at points by default when moving.
Two pusher jacks 3 are arranged below the welding gun 1, a space is reserved between the two pusher jacks 3, extrusion blocks 31 are arranged on opposite surfaces of the pusher jacks 3, the extrusion blocks 31 are arc-shaped, as shown in fig. 2, when welding is carried out, the two pusher jacks 3 which are oppositely arranged extrude the extrusion blocks 31 towards the middle, and therefore steps are further carried out to extrude the edge to be welded to .
The camera 2 is located on the left side of the welding gun 1, the extruder 4 is arranged on the left side of the pusher jack 3, and the middle through part of the extruder 4 is an extrusion hole. The extrusion hole of the extruder 4 is horn-shaped, and the inner diameter of the left end of the extrusion hole is larger than that of the right end of the extrusion hole. After the metal pipe to be welded enters the extrusion hole from the left end of the extrusion hole, the metal pipe is extruded by the inner wall of the extrusion hole, so that two sides to be welded are close to each other.
Both the correcting assembly 10 and the pusher jack 3 are arranged on the support.
working modes of the invention are as follows:
firstly, the raw material of the metal pipe is preliminarily rolled, then the raw material enters from the left end of an extrusion hole of an extruder 4, the raw material of the metal pipe which is preliminarily rolled is rounded steps when coming out from the right end of the extrusion hole due to the horn shape of the extrusion hole, then the raw material of the metal pipe reaches the lower part of a camera 2 and reaches the lower part of a welding needle 11, meanwhile, two pusher jacks 3 drive an extrusion block 31 to move towards the middle part to extrude a product to be welded, so that two edges to be welded are closer to form a pre-welding seam.
The identification base point 21 of the camera 2 tracks the pre-welded joint, the purpose is to ensure that the identification base point 21 is always positioned above the pre-welded joint, when the pre-welded joint deviates, the identification base point 21 identifies that the pre-welded joint deviates from the lower part of the pre-welded joint, and the camera 2 transmits a signal to the central controller; then the central controller controls the correction component 10 to drive the welding gun 1 to deviate towards the direction of the pre-welding seam, the pre-welding seam is welded, and after the welding gun 1 moves, the camera 2 also moves towards the welding seam.
For example, the recognition base point 21 recognizes that the pre-welded seam deviates to the left, the central controller controls the calibration assembly 10 to drive the welding gun 1 to move to the left, at this time, the welding gun 1 can be positioned right above the welded seam, and the recognition base point 21 can also be positioned above the welded seam.
All references to "up, down, left and right" herein are to be taken as references to the orientation in fig. 1, and are for convenience of description and do not have any other special meanings.
In addition, the present invention is not limited to the above embodiments, and the technical effects of the present invention can be achieved by substantially the same means, which are within the scope of the present invention.
