[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 4As shown, an embodiment of the utility model provides an auxiliary positioning fixture for zinc-aluminum-magnesium square tube processing, including a fixture base 1 and a zinc-aluminum-magnesium square tube 2, the zinc-aluminum-magnesium square tube 2 is movably connected to the top of the fixture base 1, the top of the fixture base 1 is movably connected with four right-angle positioning plates 3, four control frames 4 are provided on the top of the fixture base 1, the surface of the right-angle positioning plate 3 is in contact with the surface of the zinc-aluminum-magnesium square tube 2, and the surface of the right-angle positioning plate 3 is provided with a positioning device 5.

[0021] refer to Figure 4 The positioning device 5 includes a positioning right-angle frame 501 , a moving frame 502 is fixedly connected to the top of the positioning right-angle frame 501 , and a spring 503 is fixedly connected to the top of the positioning right-angle frame 501 .

[0022] With the above solution, by providing the positioning device 5 , when the right-angle positioning plate 3 and the limiting top plate 7 are moved to appropriate positions, the positioning device 5 has a limiting effect on the positions of the right-angle positioning plate 3 and the limiting top plate 7 .

[0023] refer to Figure 4 The surface of the right-angle positioning plate 3 is fixedly connected with a limit frame 6 used in conjunction with the moving frame 502. The inner cavity of the limit frame 6 is movably connected to the surface of the moving frame 502. The top of the spring 503 is fixedly connected to the bottom of the limit frame 6.

[0024] With the above solution, by providing the limit frame 6 , when the limit top plate 7 moves, the movable frame 502 will be driven to move along the inner cavity of the limit frame 6 , and the limit frame 6 has a limiting effect on the moving position of the movable frame 502 .

[0025] refer to Figure 2 The top of the movable frame 502 is fixedly connected to the limiting top plate 7, the bottom of the limiting top plate 7 contacts the top of the zinc-aluminum-magnesium square tube 2, and the surface of the control frame 4 is fixedly connected to the surface of the limiting top plate 7.

[0026] The above solution is adopted: by setting a limiting top plate 7, when the bottom of the limiting top plate 7 contacts the top of the zinc-aluminum-magnesium square tube 2, the limiting top plate 7 has a limiting effect on the position of the zinc-aluminum-magnesium square tube 2 moving up and down.

[0027] refer to Figure 3 The bottom of the right-angle positioning plate 3 is fixedly connected with an adjusting slider 8, and the top of the fixture bottom plate is provided with two adjusting slots 9 used in conjunction with the adjusting slider 8. The surface of the adjusting slider 8 is movably connected with the inner cavity of the adjusting slot 9.

[0028] Adopt the above scheme: by setting the adjusting slider 8 and the adjusting slot 9, when the right-angle positioning plate 3 moves, the adjusting slider 8 will be driven to move along the inner cavity of the adjusting slot 9. The coordinated use of the adjusting slider 8 and the adjusting slot 9 has a limiting effect on the moving position of the right-angle positioning plate 3.

[0029] refer to Figure 1 The top of the fixture base 1 is provided with several positioning grooves 10 for use with the positioning right-angle frame 501. The surface of the positioning right-angle frame 501 contacts the inner cavity of the positioning groove 10. The number of positioning grooves 10 is several and evenly distributed on the top of the fixture base 1.

[0030] The above solution is adopted: by setting the positioning groove 10, when the right-angle positioning plate 3 and the limiting top plate 7 are moved to the appropriate position, the control frame 4 is released, and the restoring force generated by the spring 503 restoring its shape will drive the positioning right-angle frame 501 to be stuck into the inner cavity of the positioning groove 10. The coordinated use of the positioning right-angle frame 501 and the positioning groove 10 has a limiting effect on the position of the right-angle positioning plate 3 and the limiting top plate 7.

[0031] The working principle of this utility model:

[0032] When in use, when the positioning fixture used for processing the zinc-aluminum-magnesium square tube 2 needs to position the zinc-aluminum-magnesium square tube 2 more stably, the operator first pulls the control frame 4 to the top. When the control frame 4 moves, it will drive the limit top plate 7 to move to the top. At the same time, the control frame 4 will drive the moving frame 502 to move along the inner cavity of the limit frame 6. When the moving frame 502 moves, it will drive the positioning right-angle frame 501 to move to the top. At the same time, the extrusion force generated by the movement of the positioning right-angle frame 501 will cause the spring 503 to undergo elastic deformation. When the positioning right-angle frame 501 is out of contact with the inner cavity of the positioning groove 10, the zinc-aluminum-magnesium square tube 2 is placed on the two right-angle positioning plates. 3, and then pull the right-angle positioning plate 3 toward the side close to the zinc-aluminum-magnesium square tube 2. When the surface of the right-angle positioning plate 3 contacts the surface of the zinc-aluminum-magnesium square tube 2, release the control frame 4. The restoring force generated by the spring 503 restoring its shape will drive the positioning right-angle frame 501 to be stuck into the inner cavity of the positioning groove 10, and at the same time drive the limiting top plate 7 to move to the position in contact with the top of the zinc-aluminum-magnesium square tube 2. The right-angle positioning plate 3 limits the forward and backward movement of the zinc-aluminum-magnesium square tube 2, and the limiting top plate 7 limits the upward and downward movement of the zinc-aluminum-magnesium square tube 2. At this time, the positioning fixture used for processing the zinc-aluminum-magnesium square tube 2 completes a more stable positioning of the zinc-aluminum-magnesium square tube 2.

[0033] To sum up: the auxiliary positioning fixture for zinc-aluminum-magnesium square tube processing solves the problem that the existing zinc-aluminum-magnesium square tube processing positioning fixture is a tool specially designed to fix and position the zinc-aluminum-magnesium square tube during the processing process, so as to maintain the precise position of the zinc-aluminum-magnesium square tube. Usually, the positioning fixture uses bolts to adjust the positioning accessories to position the zinc-aluminum-magnesium square tube. The bolts are easily affected by vibration and impact, resulting in loosening, which reduces the stability of the fixture. Frequent adjustment of the bolts will affect the service life of the bolts, cause aging of the bolts, and make the positioning unstable. However, the positioning fixture used in the existing zinc-aluminum-magnesium square tube processing does not have a component for more stably positioning the zinc-aluminum-magnesium square tube.
