Description

Technical Field

[0001] This utility model relates to the field of forging processing tools, and in particular to a forging welding positioning fixture. Background Technology

[0002] With the development of my country's industrial technology, high-precision equipment such as gas turbines and aero engines have gradually achieved independent research and development and independent manufacturing. These types of equipment include some shaft housing parts with complex shapes.

[0003] Currently, there is a type of shaft housing that requires a pad to be welded to its bottom. The current practice is to place the shaft housing upside down on a workbench, with multiple wedge-shaped pads arranged on the workbench to support the sides of the shaft housing. Workers need to repeatedly adjust the position of the wedge-shaped pads to prevent the shaft housing from tilting to the left or right, ensuring that the bottom of the shaft housing is level. This adjustment process takes a lot of time and affects the progress of the welding work.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] A forging welding positioning fixture includes a base plate; a support base disposed at the center of the base plate, the support base having at least two support blocks with a groove in the middle of each support block; a positioning frame disposed above the base plate, the positioning frame having a first limiting post threadedly connected to its wide side and a second limiting post and a third limiting post threadedly connected to its long side, the tail ends of the first, second, and third limiting posts extending into the space enclosed by the positioning frame and abutting against the edge of the forging; and a shaft hole positioning block horizontally arranged above the base plate.

[0007] Furthermore, the number of limiting posts 2 is even, and the limiting posts 2 are divided into two groups. The two groups of limiting posts 2 are respectively arranged on the left and right long sides of the positioning frame, and are arranged symmetrically about the center line of the wide side of the positioning frame.

[0008] Furthermore, the number of limiting posts three is set to an even number, and the limiting posts three are divided into two groups on an even basis. The two groups of limiting posts three are respectively arranged on the left and right long sides of the positioning frame, and are arranged symmetrically about the center line of the wide side of the positioning frame.

[0009] Furthermore, a contact is provided on the inner wall of the positioning frame, and the contact is arranged opposite to the limiting post.

[0010] Furthermore, a mounting column is vertically arranged on the base plate, and a limit groove is opened on the shaft hole positioning block, into which the mounting column is inserted.

[0011] Furthermore, a spring is fitted on the mounting post, and a washer is provided on the top of the spring. The washer abuts against the bottom surface of the shaft hole positioning block. The top of the mounting post has external threads, on which a locking nut is threaded and connected. The locking nut contacts the top surface of the shaft hole positioning block.

[0012] Furthermore, a vertical plate is provided on the base plate, the vertical plate being integrally formed with the base plate, and the vertical plate supporting the tail end of the shaft hole positioning block.

[0022] like Figure 1 and Figure 2 As shown, the welding positioning fixture for forging 1 includes a support base 3, which is located at the center of the base plate 2. At least two support blocks 31 are provided on the support base 3. In this embodiment, two support bases 3 are used, and the two support blocks 31 are respectively located on the two wide sides of the support base 3. A groove 311 is formed in the middle of the support block 31, and the inner wall surface of the groove 311 is set as an inclined surface. During operation, the support base 3 supports the arc-shaped portion of the outer shell of forging 1.

[0023] like Figure 1 and Figure 2 As shown, the welding positioning fixture for forging 1 includes a positioning frame 4, which is positioned above the base plate 2 and directly above the support base 3. The positioning frame 4 has a rectangular cross-section.

[0024] like Figure 1 and Figure 2 As shown, a limit post 41 is threadedly connected to the wide side of the positioning frame 4, and the tail end of the limit post 41 extends into the interior of the positioning frame 4. A contact 44 is provided on the inner wall of the other wide side of the positioning frame 4, and the contact 44 is arranged opposite to the limit post 41.

[0025] The long side of the positioning frame 4 is threaded with limit posts 42 and 43, the tail ends of which extend into the space enclosed by the positioning frame 4. There are an even number of limit posts 42; in this embodiment, there are two limit posts 42, divided into two groups, arranged symmetrically about the center line of the wide side of the positioning frame 4 on the left and right long sides respectively.
