Description

Technical Field

[0001] This utility model relates to the field of welding, specifically to a welding fixture for forgings. Background Technology

[0002] In the field of machinery manufacturing, forgings, due to their high strength, toughness, and fatigue resistance, are widely used in key industries such as aerospace, engineering machinery, automobile manufacturing, and petrochemicals, involving the production of various core components such as gears, shafts, connecting rods, and valve bodies. Welding, as a crucial joining process in forging processing, directly determines the performance stability and service life of the final product. Welding fixtures, as key equipment for ensuring welding accuracy and improving welding efficiency, are essential to the entire production process due to their rational design and reliable operation.

Detailed Implementation

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0021] See Figure 1-4 The forging welding fixture shown includes a fixture table 1, on which a first limiting support block 2 is fixedly mounted and a second limiting support block 15 is movably mounted. One end of the second limiting support block 15 is rotatably connected to the fixture table 1, and the bottom of the other end is provided with an arc-shaped slider 18. The fixture table 1 is provided with an arc-shaped slide rail 17 that slides with the arc-shaped slider 18. Both ends of the arc-shaped slider 18 protrude from the sides of the second limiting support block 15 and are provided with through holes. Nuts 19 are fixedly connected above the through holes, and fastening screws 20 are installed in the nuts 19. A first clamping unit is installed on the first limiting support block 2, and a second clamping unit is installed on the second limiting support block 15.

[0022] By implementing the above technical solution, in use, firstly, the first forging with chamfered edges is placed on the first limiting support block 2, and then the second forging with chamfered edges is placed on the second limiting support block 15. The positions of the first and second forgings are adjusted by pulling the first and second forgings and rotating the angle of the second limiting support block 15. Once the chamfers to be welded on the first and second forgings are aligned, the first forging is clamped by the first clamping unit, and the second forging is clamped by the second clamping unit. Then, the fastening screws 20 are tightened to fix the position of the arc-shaped slider 18, and welding can then be performed. Alternatively, the position of the arc-shaped slider 18 can be fixed first by the fastening screws 20, and then clamped by the second clamping unit.

[0023] In this embodiment, both the first limiting support block 2 and the second limiting support block 15 are provided with through limiting grooves 3. When passing through the limiting grooves 3, the first forging or the second forging can be pulled and adjusted within them, and can be limited to the left and right.

[0024] In this embodiment, to further provide a first clamping unit, the first clamping unit includes a first gantry frame 4 and a first cylinder 5 mounted on the first gantry frame 4, wherein the cylinder shaft of the first cylinder 5 extends downward and is connected to a first pressure block 6.

[0025] In this embodiment, to further provide a second clamping unit, the second clamping unit includes a second gantry frame 7 and an elastic zipper mounted on the second gantry frame 7, with a second pressure block 12 provided at the lower end of the elastic zipper. When the second forging is pulled and adjusted, after adjustment, the elastic zipper is released, and the second pressure block 12 is pressed onto the second forging under the action of the spring 11. Since the forging is not subjected to excessive force during welding, the pressing force of the spring 11 is sufficient to temporarily fix the second forging, and pulling the elastic zipper can also improve the efficiency of temporarily fixing the second forging.

[0026] In this embodiment, to further provide an elastic zipper, the elastic zipper includes a pull rod 8, with a handle 9 at the upper end, a second pressure block 12 at the lower end, and an upper limit plate 10 in the middle. A spring 11 is sleeved on the pull rod 8 between the second pressure block 12 and the bottom surface of the second portal frame 7. When pulled upward, the spring 11 is compressed, giving it a downward pressing force.

[0027] In this invention, if the length of the forging to be clamped is long, the length of the first limiting support block 2 and the second limiting support block 15 can be appropriately increased.

[0028] In this embodiment, a rotating plate 16 is provided at the end of the second limiting support block 15, and a rotating shaft 21 rotatably connected to the rotating plate 16 is provided on the tooling table 1. This arrangement allows the second limiting support block 15 to rotate around the rotating shaft 21, thus adjusting the welding angle.

[0029] In this embodiment, mounting holes 13 are provided at the four corners of the tooling table 1, and support columns 14 are provided at the bottom of the tooling table 1 at the mounting holes 13. This arrangement facilitates the fixing of the tooling table 1 to the corresponding work position using bolts. To avoid interference from the protruding bolt parts on the rotation of the second limiting support block 15, the mounting holes 13 can be countersunk holes, with the bolt heads recessed within them.

[0030] In this embodiment, the cross-section of the arc-shaped slider 18 is T-shaped. This design allows the arc-shaped slider 18 and the arc-shaped slide rail 17 to slide stably together, preventing slippage.

[0031] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0033] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
