Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment and relates to a rim welding machine. Background Art

[0002] In an extra-large rim production line, it is necessary to weld the web plates to achieve welding automation. However, due to the overly large volume of the extra-large rim, it is not convenient to handle. In the prior art, the fixed welding torch will compress the handling space of the rim, and the space is too small, which makes it very difficult for the assisting mechanism to enter above the workbench to assist in handling, resulting in inconvenient loading and unloading, high operation difficulty, and low production efficiency.

[0003] The patent document with the application number 201520051324.8 provides a double-gun rim welding machine. The left and right pushing devices of the welding machine can respectively move the left and right welding torches a certain distance left and right. However, the moving distance is limited, and the left and right welding torches cannot move forward and backward, and the left and right welding torches still affect the handling of the rim. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the utility model provides a rim welding machine. The technical problem to be solved by the utility model is: how to facilitate loading and unloading.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] A rim welding machine includes a workbench. It is characterized in that mounting frames are respectively arranged on the left and right sides of the workbench, a first welding torch and a second welding torch are respectively arranged on the mounting frames, and driving members for respectively driving the corresponding mounting frames to move back and forth are further arranged on the workbench.

[0007] When it is necessary to handle the rim, the driving members respectively drive the corresponding mounting frames to move backward, and each mounting frame drives the first welding torch and the second welding torch to move to the rear side of the workbench. The mounting frames and the welding torches are all located at the rear side of the workbench, thus freeing up the space at the front side and the middle part of the workbench. The assisting mechanism can conveniently handle the rim, especially the extra-large rim, and the loading and unloading are more convenient.

[0008] In the above-mentioned rim welding machine, a first air cylinder and a vertically extending first guide rail are respectively arranged on the mounting frame. A bracket is slidably connected to the first guide rail. The first welding torch and the second welding torch are respectively mounted on the corresponding brackets, and the piston rod of the first air cylinder is connected to the corresponding bracket.

[0009] The first air cylinder drives the bracket to move up and down, and the bracket drives the corresponding first welding torch and second welding torch to move up and down, so as to correspondingly adjust the position of the welding torch according to the height of the rim, improving the adaptability.

[0010] In the above-mentioned rim welding machine, fine adjustment modules are respectively arranged on the bracket, and the first welding torch and the second welding torch are respectively installed on the corresponding fine adjustment modules.

[0011] By using the fine adjustment modules, the positions and angles of the first welding torch and the second welding torch can be finely adjusted to achieve precise positioning of the welding torches.

[0012] In the above-mentioned rim welding machine, fixing plates are respectively arranged on the left side and the right side of the workbench. Guide rails II extending forward and backward are respectively arranged on the fixing plates. The mounting brackets are slidably connected to the corresponding guide rails II. Connecting plates are respectively fixed on the mounting brackets. The driving member includes a second cylinder. The second cylinder is installed on the corresponding fixing plate, and the piston rod of the second cylinder is connected to the corresponding connecting plate.

[0013] The second cylinder drives the mounting bracket to move forward and backward through the connecting plate, and the first welding torch and the second welding torch move forward and backward along with the corresponding mounting bracket.

[0014] As another embodiment, the second cylinder can also be replaced by an oil cylinder or a linear motor.

[0015] When it is necessary to carry the rim, the second cylinder drives the corresponding mounting bracket to move backward respectively. Each mounting bracket drives the first welding torch and the second welding torch to move to the rear side of the workbench, vacating the space at the front side and the middle part of the workbench, so that the assisting mechanism can conveniently carry the rim;

[0016] After the rim is placed, the second cylinder drives the corresponding mounting bracket to move respectively. Each mounting bracket drives the first welding torch and the second welding torch to move above the rim, and adjusts the position of the welding torch according to the position of the rim to achieve precise welding of the rim.

[0017] In the above-mentioned rim welding machine, the rear end part of the fixing plate extends out from the rear side of the workbench, and the guide rail II on the fixing plate extends to the rear end part of the fixing plate.

[0018] The rear end part of the guide rail II extends beyond the rear part of the workbench. When the mounting bracket moves to the rear end part of the guide rail II, the mounting bracket and the welding torch are both located at the further rear side of the workbench. This structure can vacate the space of the entire workbench, making it easier to carry the rim and further improving the convenience of operation.

[0019] In the above-mentioned rim welding machine, a rim mounting seat and a rotating module for driving the rim mounting seat to rotate are arranged on the workbench. The rim mounting seat is located above the workbench, and the rotating module is located below the workbench.

[0020] The rim mounting seat is used for placing and fixing the rim. The rotating module drives the rim mounting seat to rotate evenly, so that the first welding torch and the second welding torch can more conveniently and precisely weld the rim.

[0021] In the above-mentioned rim welding machine, the rotation module is a motor or a rotary cylinder.

[0022] Compared with the prior art, the advantages of the present utility model are as follows:

[0023] This rim welding machine can move both the mounting bracket and the welding torch to the rear side of the workbench, leaving the space in the front and middle parts of the workbench. The assisting mechanism can conveniently carry the rim, making the loading and unloading more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
