Technical Field
[0001] This utility model relates to the technical field of welding devices, specifically a welding device for assembling a tie rod bearing mounting plate and a bearing. Background Technology
[0002] Automotive tie rod brackets are components located on the chassis of a car. For example... Figure 1 As shown, the automotive tie rod bracket includes a base plate 83 and two parallel tie rod bearing mounting plates 8 mounted on the upper side of the base plate 83. The tie rod bearing mounting plates 8 have bearing mounting holes 82, and each bearing mounting hole 82 has a bearing 83. During assembly, all components are fixed together using a clamp by welding, and then all components are welded together to form the tie rod bracket.
[0003] Currently, the welding of the tie rod bearing mounting plate 8 and the bearing 83 is done manually, which is complicated, labor-intensive, and has low welding efficiency. It is easy to cause deviations in the welding position, which affects the welding quality of the tie rod bracket.
[0004] Based on this, the present invention proposes a welding device for assembling and welding a tie rod bearing mounting plate and a bearing. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention proposes a welding device for assembling and welding a tie rod bearing mounting plate and a bearing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A welding device for assembling a tie rod bearing mounting plate and a bearing is characterized in that it includes a worktable, a transverse moving device mounted on the top of the worktable, a transverse moving frame mounted on the transverse moving device, and a clamping welding device connected to the transverse moving frame via a lifting device.
[0008] The clamping welding device includes a lifting frame, a rotating sleeve, a top stop plate with a diameter larger than the inner diameter of the rotating sleeve, and a vertical shaft passing through the rotating sleeve. The lifting frame is vertically mounted with the rotating sleeve and a rotating device connected to the rotating sleeve. The top stop plate is coaxially threaded to the top of the vertical shaft, and a truncated cone-shaped pressure block with a larger top and smaller bottom is coaxially connected to the bottom. The top diameter of the pressure block is larger than the inner diameter of the rotating sleeve. A spring is fitted between the rotating sleeve and the pressure block on the vertical shaft. A welding torch bracket is connected to the rotating sleeve and is connected to the welding torch. The bottom end of the welding torch is located on one side of the bottom end of the pressure block. A welding box is connected to the top of the transverse frame and is connected to the welding torch through a flexible hose. Several supports for tie rod bearing mounting plates are arranged horizontally on the worktable. The tie rod bearing mounting plates are provided with shaft holes, and bearings are provided in the shaft holes. The centroids of each bearing are located on a horizontal line, and the horizontal line is located directly below the pressure block.
[0009] During operation, tie rod bearing mounting plates are placed on each support, and bearings are inlaid into the shaft holes of each tie rod bearing mounting plate. Then, the lateral movement device drives the lateral movement frame to move, causing the pressure block to move directly above a bearing. The lateral movement device then stops driving the lateral movement frame. The lifting device drives the lifting frame to descend, the pressure block presses down on the bearing, the lifting device stops driving the lifting frame, and the rotating sleeve rotation device drives the rotating sleeve to rotate 360 degrees clockwise. At the same time, the welding torch works to weld the gap between the bearing and the shaft hole. Then, the lifting device drives the lifting frame to rise.
[0010] The transverse movement device drives the transverse frame to move, causing the pressure block to move directly above the other bearing. The transverse movement device then stops driving the transverse frame. The lifting device drives the lifting frame to descend, the pressure block presses down on the bearing, and the lifting device stops driving the lifting frame. The rotating sleeve rotation device drives the rotating sleeve to rotate 360 degrees counterclockwise. At the same time, the welding torch works to weld the gap between the bearing and the shaft hole. Then, the lifting device drives the lifting frame to rise.
[0011] Repeat this process until all tie rod bearing mounting plates are welded.
[0012] Its beneficial effects are as follows: a spring is fitted between the rotating sleeve on the vertical shaft and the pressure block. During welding, this effectively presses down the tie rod bearing mounting plate without damaging the parts, and the vertical shaft does not obstruct the rotation of the rotating sleeve. The welding torch rotates 360 degrees to weld the gap between the bearing and the shaft hole, resulting in a strong and rapid weld. It features multiple workstations, allowing for the replacement of the tie rod bearing mounting plate at some workstations while welding at others. It is characterized by its simple structure, convenient operation, rapid welding, high welding efficiency, and labor savings.

During welding, this spring 46 can effectively press down the tie rod bearing mounting plate 8 without damaging the parts, and the vertical shaft 44 will not obstruct the rotation of the rotating sleeve 42.
