Description

Technical Field

[0001] The utility model relates to the technical field of automobile welding production lines, and more specifically, to an automatic welding production line for automobile wheelhouse outer panels. Background Art

[0002] When welding the existing wheelhouse outer panels (automobile wheel cover outer panels), it is necessary to weld each component together. For example, the publication number is CN117506240A, and the name is an automatic line and welding production method for a white body front wheelhouse assembly welding assembly, which includes two symmetrically distributed front wheelhouse production lines to realize the production of left and right front wheelhouse assemblies. However, setting up two front wheelhouse production lines not only increases production costs but also increases the floor area of the production workshop.

[0003] Therefore, how to provide an automatic welding production line for automobile wheelhouse outer panels that can weld the left and right wheelhouse outer panels simultaneously without investing in two production lines is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0004] In view of this, the utility model provides an automatic welding production line for automobile wheelhouse outer panels that can weld the left and right wheelhouse outer panels simultaneously without investing in two production lines.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic welding production line for automobile wheelhouse outer panels includes: a line body. On one side of the line body, in the production direction, there are successively arranged a first assembly and positioning station for loading and splicing the first batch of parts of the right wheelhouse outer panel, a second assembly and positioning station for loading and splicing the second batch of parts of the right wheelhouse outer panel, and a first repair welding and unloading station for repair welding the right wheelhouse outer panel assembly. On the other side of the line body, in the production direction, there are successively arranged a third assembly and positioning station for loading and splicing the left wheelhouse outer panel parts and a second repair welding and unloading station for repair welding the left wheelhouse outer panel. In the middle of the line body, in the production direction, there are successively arranged a first spot welding robot, a first handling robot, a first transfer table system, a second transfer table system, a second handling robot, a second spot welding robot, a third handling robot, and a third spot welding robot.

[0007] The first assembly and positioning station and the third assembly and positioning station are arranged oppositely, and the first spot welding robot is located between the first assembly and positioning station and the third assembly and positioning station.

[0008] The second assembly and positioning station and the second repair welding and unloading station are arranged oppositely, and the second spot welding robot is located between the second assembly and positioning station and the second repair welding and unloading station.

[0009] The first transition table system and the second transition table system are arranged side by side.

[0010] As can be seen from the above technical solutions, compared with the prior art, the present utility model discloses an automatic welding production line for the outer panel of an automotive wheel housing. This production line can simultaneously weld and produce the outer panels of the left and right wheel housings through the cooperation of each station in the line body, without the need to invest in two production lines, greatly reducing the equipment investment cost and the floor area of the production workshop.

[0011] Furthermore, it further includes a first stud welding system disposed on one side of the line body and close to the first assembly and positioning station, and a second stud welding system disposed on the other side of the line body and close to the second repair welding and blanking station.

[0012] The beneficial effect of adopting the above solution is that it can also automatically weld the studs on the outer panel of the wheel housing (these studs are mainly used to fix cables), without the need to additionally set up a stud welding line body, greatly improving the welding production efficiency of the outer panel of the wheel housing.

[0013] The present utility model provides a production method for an automatic welding production line of the outer panel of an automotive wheel housing. The following production steps are carried out using the described production line:

[0014] Step 1: Manually place the first batch of parts of the right wheel housing on the first assembly and positioning station, and at the same time place the outer panel parts of the left wheel housing on the third assembly and positioning station;

[0015] Step 2: The first spot welding robot welds the first batch of parts on the first assembly and positioning station. At this time, after the first batch of parts are welded, they become a semi-finished right wheel housing. Then, the first spot welding robot welds the outer panel parts of the left wheel housing on the third assembly and positioning station. After welding, they become a pre-finished left wheel housing. At the same time, the first handling robot grabs the semi-finished right wheel housing on the first assembly and positioning station and places it on the first transition table system. After being transported by the first transition table system to the grabbing station of the second handling robot, the second handling robot grabs the semi-finished right wheel housing from the first transition table system and places it on the second assembly and positioning station. Manually place the second batch of parts of the right wheel housing on the second assembly and positioning station. The second spot welding robot welds the second batch of parts and the semi-finished right wheel housing. After welding, they become a pre-finished right wheel housing. Then, the third handling robot grabs the pre-finished right wheel housing on the second assembly and positioning station and places it on the first repair welding and blanking station for repair welding. After welding, it becomes a right wheel housing assembly and is blanked;

[0016] After the first handling robot places the semi-finished right wheel cover on the first transfer table system, the first handling robot grabs the pre-finished left wheel cover at the third assembly and positioning station and places it on the second transfer table system. Then, it is transferred by the second transfer table system to the grasping station of the second handling robot. After that, the second handling robot grabs the pre-finished left wheel cover from the second transfer table system and places it on the second repair welding and blanking station for repair welding. After welding, it becomes the left wheel cover assembly and is blanked.

[0017] Further, in step two, the first handling robot grabs the semi-finished right wheel cover at the first assembly and positioning station and cooperates with the first stud welding system for stud welding. Then, the semi-finished right wheel cover welded with studs is placed on the first transfer table system; the second handling robot grabs the pre-finished left wheel cover from the second transfer table system and cooperates with the second stud welding system for stud welding. Then, the pre-finished left wheel cover welded with studs is placed on the second repair welding and blanking station for repair welding operations.

[0018] The production method of the present utility model can realize the automated production of left and right wheel cover outer plate products from assembly, splicing welding, stud welding, handling, etc. The overall production efficiency is high, and it avoids the problems of low production efficiency, high labor intensity, and high quality risk caused by manual transfer and process processing of parts in the existing method.
