Technical Field
[0001] This utility model relates to the field of welding tooling technology, specifically a welding mold for an undercarriage X-frame. Background Technology
[0002] The X-frame underframe is a type of excavator underframe structural component, mainly used in conjunction with the left and right side beams to enable the excavator to move. Its structure is mainly composed of major components such as the cap, upper and lower cover plates, and vertical stiffeners, and is manufactured through assembly, welding, and processing.
[0003] Currently, the lack of welding molds makes it impossible to quickly position the X-frame during welding of the lower frame, resulting in low processing efficiency. Therefore, there is an urgent need for a welding mold for the X-frame of the lower frame to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a welding mold for the X-frame of the undercarriage to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A welding mold for an X-frame underframe includes a workbench. Bases are connected to the bottom of the workbench at three points: left, center, and right. A concentric positioning seat pattern is positioned at the center of the top of the workbench. A front support frame is positioned on the top of the workbench and behind the concentric positioning seat pattern. A rear support frame is positioned on the top of the workbench and in front of the concentric positioning seat pattern. Support frames are positioned on the left and right sides of the top of the workbench and on the rear support frame. Support platforms are positioned at the four corners of the concentric positioning seat pattern. Ear plate opening seats are installed on both sides of the top of the workbench near the edge. A limit seat is positioned on one side of each ear plate opening seat.
[0006] As a preferred embodiment of this utility model, the number of limiting seats is set to three, and the three limiting seats are respectively located at the three corners of the top of the worktable.
[0007] As a preferred technical solution of this utility model, the four support platforms are arranged in pairs facing each other about the concentric positioning seat pattern, and there are gaps between the four support platforms and both sides of the concentric positioning seat pattern.
[0008] As a preferred embodiment of this utility model, the number of ear plate opening seats is set to four.
[0009] As a preferred embodiment of this utility model, the two limiting seats are arranged symmetrically about the rear support frame.
[0010] As a preferred embodiment of this utility model, the two support frames are arranged symmetrically about the rear support frame.
[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model, by setting up a concentric positioning seat pattern, a front support frame, a rear support frame, a support frame, a support platform, an ear plate opening seat, and a limiting seat, utilizes the mutual cooperation between them to achieve rapid positioning during the welding of the X-frame of the lower frame, while meeting the drawing requirements and improving processing efficiency.

[0015] Please see Figure 1-6A welding mold for an X-frame underframe includes a workbench 1. Bases 2 are connected to the bottom of the workbench 1 at three points: left, center, and right. A concentric positioning seat ring template 3 is positioned at the center of the top of the workbench 1. A front support frame 4 is positioned on the top of the workbench 1 and behind the concentric positioning seat ring template 3. A rear support frame 7 is positioned on the top of the workbench 1 and in front of the concentric positioning seat ring template 3. Support frames 6 are positioned on the top of the workbench 1 and on both the left and right sides of the rear support frame 7. Support platforms 5 are positioned at the four corners of the concentric positioning seat ring template 3. Ear plate opening seats 8 are installed on both sides of the top of the workbench 1 near the edge. A limit seat 9 is positioned on one side of each ear plate opening seat 8.
[0016] The number of limit seats 9 is set to three, and the three limit seats 9 are located at the top three corners of the worktable 1.
[0017] Among them, the four support platforms 5 are arranged in pairs opposite to the concentric positioning seat pattern 3, and there are gaps between the four support platforms 5 and the two sides of the concentric positioning seat pattern 3.
[0018] The number of ear plate opening seats 8 is set to four.
[0019] Among them, the two limiting seats 9 are arranged symmetrically about the rear support frame 7.
[0020] Among them, the two support frames 6 are arranged symmetrically about the left and right axes about the rear support frame 7.
[0021] The working principle and usage process of this utility model are as follows: First, during operation, the lower frame X-frame 10 is placed on the concentric positioning seat pattern 3 for positioning. The left and right sides of the lower frame X-frame 10 are positioned by the four ear plate opening seats 8, and the three corners of the lower frame X-frame 10 are limited by the three limiting seats 9. The middle part of the lower frame X-frame 10 is supported and positioned by the front support frame 4, the rear support frame 7, the support platform 5, and the support frame 6. This allows for rapid positioning of the lower frame X-frame 10 during welding, meets the drawing requirements, and improves processing efficiency.
