Description

Technical Field

[0001] The utility model relates to the field of welding assistance, in particular to a Yuanbao beam welding auxiliary device for improving the accuracy of a welding machine. Background Art

[0002] Welding of Yuanbao beams refers to the welding repair of damaged Yuanbao beams during the vehicle maintenance process. Yuanbao beams are an important component of the vehicle chassis, connecting the body and suspension system, and bearing the weight of the body and suspension force. During the use of the vehicle, Yuanbao beams may be damaged due to impact, wear and other reasons.

[0003] At present, when welding the Yuanbao beam, due to its shape similar to that of a Yuanbao, it is difficult to fix it. It needs to be fixed at three points, namely the middle and the left and right ends, which is very troublesome. In addition, the fixation of the left and right ends is easily affected by the model, resulting in the problem of loose fixation, and there is a risk of skewness. Utility Model Content

[0004] Based on the above description, the utility model provides a Yuanbao beam welding auxiliary device for improving the accuracy of a welding machine, so as to solve the problem that the existing welding auxiliary device is prone to skew when fixing Yuanbao beams of different models.

[0005] The utility model solves the above technical problems with the following technical solutions: a Yuanbao beam welding auxiliary device for improving the welding machine precision, comprising a workbench;

[0006] Support components and limit components are arranged on both sides of the top surface of the workbench, and the limit components are located above the support components, and each support component corresponds to each limit component one by one;

[0007] A fixing component is arranged in the middle of the top surface of the workbench. There are four fixing components in number, and the four fixing components are evenly distributed on the workbench.

[0008] Furthermore, the support assembly includes a support base and a lifting portion, the support base is installed on a workbench, and the lifting portion is located on the top surface of the support base.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the lifting part is composed of a supporting block, a limiting column and a threaded rod, the supporting block is fixedly mounted on the support seat, the limiting column and the threaded rod are both located on the supporting block, and the diameter of the cross section of the limiting column increases from top to bottom.

[0011] Furthermore, a circular groove is provided on the top surface of the support block, the limiting column is inserted into the inside of the circular groove, a threaded groove is provided on the side surface of the support block, one end of the threaded rod is inserted into the inside of the threaded groove, and is threadedly connected to the threaded groove.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, a baffle is fixedly connected to the surface of the limiting column, a spring is fixedly installed on one side of the baffle, and one end of the spring away from the baffle is fixedly connected to the inner wall of the circular groove.

[0014] Furthermore, the limiting assembly includes a hydraulic column, a mounting seat, a pressure rod and a first pressure plate. The hydraulic column and the mounting seat are both installed on a workbench. One end of the pressure rod is fixedly connected to the top of the hydraulic column, and one end of the first pressure plate is fixedly connected to the end face of the pressure rod.

[0015] Furthermore, the fixing assembly consists of a fixing seat, a first fixing plate, a second fixing plate and a second pressing plate. The fixing seat is installed on the workbench, the first fixing plate and the second fixing plate are installed on the fixing seat, and one end of the first pressing plate is installed on the fixing seat, and the other end is located above the first fixing plate and the second fixing plate.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. The utility model arranges a support assembly on the workbench to prevent the Yuanbao beam from being placed on the supporting block in the support assembly. At the same time, a limit column is passed through the mounting hole of the Yuanbao beam, and the pressure rod and the first pressure plate in the upper limit assembly are cooperated to limit and fix the end face of the Yuanbao beam, thereby putting the Yuanbao beam in a stable state, which is convenient for subsequent welding of the Yuanbao beam.

[0018] 2. By opening a threaded groove on one side of the support block and cooperating with the rotation of the threaded rod, the threaded rod can push the limit column to move upward. Since the cross-sectional diameter of the limit column increases from small to large, the limit column can adapt to different types of Yuanbao beam mounting holes, while avoiding the gap between the limit column and the mounting hole due to the large diameter of the mounting hole, which makes the Yuanbao beam prone to tilting left and right.

[0038] The bottom end surface of the limiting column 2022 is designed to be inclined, and the end surface of the threaded rod 2023 is designed to be hemispherical, so that the end surface of the threaded rod 2023 fits with the bottom of the limiting column 2022.
