[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0025] Example 1
[0026] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an auxiliary welding fixture for turbine housing production, including a welding base frame 1, two chuck housings 2, a turbine housing 3, two turbine housing chucks 4, two rubber anti-slip pads 5, and two rotating handles 6. The inner cavity of the welding base frame 1 is movably connected to the surface of the chuck housings 2. The turbine housing 3 is disposed on the top of the welding base frame 1. The rubber anti-slip pads 5 are fixedly connected to the surface of the turbine housing chucks 4. The opposite sides of the two rubber anti-slip pads 5 are in close contact with the inner cavity of the turbine housing 3. The rotating handles 6 are disposed on the opposite sides of the two turbine housing chucks 4.
[0027] Chuck adjustment device 7 is located inside the chuck housing 2.
[0028] Specifically, by setting up the chuck adjustment device 7, the limiting plate shell 8, and the adjustment groove 9, when the turbine chuck needs to move to a position that contacts the inner cavity of the turbine housing 3, or to disengage from the inner cavity of the turbine housing 3, the coordinated use of the chuck adjustment device 7, the limiting plate shell 8, and the adjustment groove 9 has an adjustment effect on the position of the turbine housing 3.
[0029] Furthermore, when the welding fixture used in the production of turbine housing 3 is used to conveniently position the welded object, the user first places the turbine housing 3 on one side opposite to the two turbine housing chucks 4, and then presses the two column pressing frames 11 on one side opposite to each other. When the column pressing frame 11 moves, it will generate a pressing force on the translational cylinder 10. The translational cylinder 10 subjected to the pressing force will drive the limiting column 702 to move along the inner cavity of the limiting plate shell 8. When the limiting column 702 moves, it will drive the chuck adjusting block 701 to move. At the same time, the force generated when the chuck adjusting block 701 moves causes the tension spring 703 to undergo elastic deformation. When the chuck adjusting block 701 has completely moved into the inner cavity of the chuck shifting shell 2, the turbine housing chuck 4 is pulled towards the side closer to the turbine housing 3, driving the chuck shifting shell 2 along the inner cavity of the turbine housing 3. As the inner cavity of the welding base frame 1 moves, the stabilizing frame 12 moves along the surface of the welding base frame 1. When the rubber anti-slip pad 5 on the surface of the turbine housing chuck 4 is in close contact with the inner cavity of the turbine housing 3, the shifting column extrusion frame 11 is released. The restoring force generated by the spring 703 returning to its shape will drive the chuck adjusting block 701 to be inserted into the inner cavity of the adjusting groove 9. At this time, the position of the turbine housing 3 is restricted. During welding, the operator can rotate the rotating handle 6. The rotating handle 6 will drive the rotating block 14 to rotate along the inner cavity of the rotating chuck 13, and at the same time drive the turbine housing chuck 4 and the turbine housing 3 to rotate. The cooperative use of the rotating block 14 and the rotating chuck 13 has an adjustment effect on the angle of the turbine housing 3 during welding. At this time, the welding fixture for the production of the turbine housing 3 can conveniently position the welded object.
[0030] Example 2
[0031] In the second embodiment of this utility model, the chuck adjustment device 7 includes two chuck adjustment blocks 701. The opposite sides of the two chuck adjustment blocks 701 penetrate the chuck shifting shell 2 and extend to the outer side of the inner cavity of the chuck shifting shell 2. The opposite sides of the two chuck adjustment blocks 701 are fixedly connected to two limiting posts 702. The surface of the limiting posts 702 is fitted with a tension spring 703. The surface of the tension spring 703 is fixedly connected to the surface of the chuck adjustment block 701. The inner cavity of the chuck shifting shell 2 is fixedly connected to four limiting plate shells 8 that cooperate with the limiting posts 702. The surface of the limiting posts 702 is movably connected to the inner cavity of the limiting plate shells 8. The top and bottom of the inner cavity of the welding base frame 1 are provided with several adjustment grooves 9 that cooperate with the chuck adjustment blocks 701. The surface of the chuck adjustment blocks 701 is in contact with the inner cavity of the adjustment grooves 9.
[0032] Specifically, by setting up the chuck adjustment device 7, the limiting plate shell 8, and the adjustment groove 9, when the turbine housing chuck 4 needs to position the turbine housing 3, the coordinated use of the chuck adjustment device 7, the limiting plate shell 8, and the adjustment groove 9 has a limiting effect on the position of the turbine housing 3.
[0033] Furthermore, the translational cylinder 10 subjected to the compressive force will drive the limiting post 702 to move along the inner cavity of the limiting plate shell 8. When the limiting post 702 moves, it will drive the chuck adjusting block 701 to move. At the same time, the force generated when the chuck adjusting block 701 moves will cause the tension spring 703 to undergo elastic deformation. The restoring force generated by the tension spring 703 returning to its shape will drive the chuck adjusting block 701 to be inserted into the inner cavity of the adjusting groove 9. At this time, the position of the turbine shell 3 is restricted.
[0034] Example 3
[0035] In the third embodiment of this utility model, a rotating clasp 13 is fixedly connected to the top of the stabilizing frame 12, and a rotating block 14 is movably connected to the inner cavity of the rotating clasp 13. The left and right sides of the rotating block 14 penetrate the rotating clasp 13 and extend to the outer side of the inner cavity of the rotating clasp 13. The surface of the rotating block 14 is fixedly connected to the surface of the turbine housing chuck 4, and the surface of the rotating block 14 is fixedly connected to the surface of the rotating handle 6.
[0036] Specifically, by setting a rotating retainer 13 and a rotating retainer 14, when the turbine housing 3 rotates, it will drive the rotating retainer 14 to rotate along the inner cavity of the rotating retainer 13. The cooperation between the rotating retainer 14 and the rotating retainer 13 has a limiting effect on the rotation position of the turbine housing 3.
[0037] Furthermore, during welding, the operator can rotate the rotating handle 6, which will cause the rotating block 14 to rotate along the inner cavity of the rotating chuck 13, and at the same time drive the turbine housing chuck 4 and the turbine housing 3 to rotate. The coordinated use of the rotating block 14 and the rotating chuck 13 has an adjustment function for the angle of the turbine housing 3 during welding.
[0038] In summary, by setting the chuck adjustment device 7, the welding fixture used in the production of turbine housing 3 can be conveniently positioned to weld the workpiece.
