Description

Technical Field

[0001] This utility model relates to the field of spot welding machine technology, specifically a gantry-type spot welding machine. Background Technology

[0002] Spot welding machines are mechanical devices that use resistance heating to join metals. They achieve rapid welding by generating high temperatures and applying pressure at the contact points of workpieces through current. They are widely used in automobile manufacturing, electronics industry and other fields.

[0003] For example, Chinese Patent CN114905129A (A gantry spot welding machine that is easy to move and its moving method): includes a built-in mobile trolley inside the bottom working box, and the built-in mobile trolley is slidably connected to the bottom working box. The outer side of the built-in mobile trolley is respectively equipped with a first track wheel and a second track wheel, and the first track wheel and the second track wheel are fixedly connected to the built-in mobile trolley by a coupling. Tracks are installed on the outer side of the first track wheel and the second track wheel, and the first track wheel and the second track wheel are in contact with the track. A base is provided below the bottom working box, and the base and the bottom working box are set as an integral structure. A lifting device is installed above the bottom working box, and the lifting device is fixedly connected to the bottom working box by bolts.

[0004] However, most existing gantry-type spot welding machines have placement racks that are connected to moving guide rails, requiring components to be placed one by one, which is time-consuming and labor-intensive, affecting spot welding efficiency. Therefore, this does not meet the current needs, and we have proposed a gantry-type spot welding machine. Utility Model Content

[0005] The purpose of this utility model is to provide a gantry-type spot welding machine to solve the problem mentioned in the background art that the placement rack of most existing gantry-type spot welding machines is connected to the moving guide rail, requiring components to be placed one by one, which makes placement and retrieval time-consuming and laborious, affecting spot welding efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gantry-type spot welding machine, comprising: a base, wherein a first slide rail is provided inside the base, and multiple first slide rails are provided; a placement component is provided at the moving end of the first slide rail, and the placement component moves with the first slide rail; the placement component includes a placement platform and a connecting part, and the placement platform and the connecting part are detachably connected; uprights are provided on both sides of the rear end of the base; a second slide rail is provided at the upper end of the uprights; a sliding frame is provided at the moving end of the second slide rail; and a third slide rail is provided on one side of the sliding frame.

[0007] Preferably, the connecting part includes a connecting base and a limiting top plate, and the limiting top plate is located at the upper end of the connecting base. The upper surface of the connecting base is provided with a mounting hole, and the mounting hole penetrates the connecting base. The connecting base is connected to the moving end of the first slide rail through the mounting hole external bolt.

[0008] Preferably, the lower surface of the limiting top plate is provided with a threaded groove, and the center of the upper surface of the connecting base is provided with a threaded post, and the threaded post is threadedly connected to the threaded groove.

[0009] Preferably, an alignment bracket is provided at one corner of the connecting base, and the alignment bracket is fixed to the connecting base by external screws.

[0010] Preferably, the lower surface of the placement platform is provided with a limiting slot, and the limiting top plate is inserted into the limiting slot. The upper surface of the placement platform is provided with placement holes, and there are several placement holes.

[0011] Preferably, a mounting bracket is provided on one side of the third slide rail, and a spot welding head is provided at the lower end of the mounting bracket; a controller is provided on one side of the second slide rail.

[0012] Preferably, a pipe rack is provided on one side of the mounting bracket, and a pipe is inserted inside the pipe rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the limiting top plate is installed on the connecting base, the limiting top plate is threadedly connected to the threaded column through the threaded groove, which facilitates the disassembly and replacement of the limiting top plate. This eliminates the need to separate the connecting base from the first slide rail, thus improving the ease of disassembly. Furthermore, when the placement platform is installed on the upper part of the limiting top plate, the limiting top plate is inserted into the limiting slot during installation, which limits the placement platform, prevents positional deviation, improves the positioning effect, and thus improves the accuracy of spot welding. After spot welding an object fixed on one placement platform, spot welding can be performed on an object fixed on another placement platform. At this time, the placement platform can be removed, and multiple objects can be removed directly by tilting, without having to remove them one by one. Moreover, the placement platform with the pre-placed items can be directly connected to the limiting top plate, which improves the spot welding efficiency of the spot welding machine. This solves the problem that most of the placement frames of existing gantry-type spot welding machines are connected to the moving guide rail, requiring the placement of each component one by one, which leads to time-consuming and laborious placement and retrieval, affecting the spot welding efficiency.

[0015] (2) An alignment frame is set at one corner of the connecting base. The alignment frame is a right-angle structure and is fixed by external screws to limit the limit plate, prevent it from rotating and falling, and improve the safety and stability of the limit plate after installation.

[0023] The connecting base 17 is connected to the moving end of the first slide rail 2 through the external bolts of the mounting hole 19. After the connection is completed, the limiting top plate 16 is installed on the upper end of the connecting base 17. During the connection, the limiting top plate 16 is threadedly connected to the threaded post 20 through the threaded groove 21, which makes it easy to disassemble and replace the limiting top plate 16, so that the connecting base 17 does not need to be separated from the first slide rail 2, thus improving the convenience of disassembly.

[0024] Then, the alignment frame 18 is installed at one corner of the connecting base 17 and fixed with external screws to limit the limit plate 16, prevent it from rotating and falling, and improve the safety and stability of the limit plate 16 after installation.
