DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1: Figure 1 to Figure 6 As shown, this embodiment proposes a rotary tooling flange, including a first workpiece 1, a second workpiece 3 and an electric cylinder 9, the inner wall of the first workpiece 1 is provided with a clamping groove 15, the outer wall of the first workpiece 1 is movably mounted with a first flange 2, one end of the first workpiece 1 is movably connected with the second workpiece 3, the inner wall of the second workpiece 3 is mounted with an electric cylinder 9 through a mounting block 8, the driving shaft of the electric cylinder 9 is connected with a push-pull rod 10, and limiting blocks 11 are symmetrically arranged at both ends of the push-pull rod 10, the second workpiece 3 is movably mounted with the limiting block 11 through a limiting groove 17, a clamping block 12 is symmetrically and movably installed in the middle position of the limiting block 11, and the inner wall of the second workpiece 3 away from the end of the electric cylinder 9 is symmetrically provided with movable grooves 7, the inner walls of the movable grooves 7 are all mounted with rotating shafts 13, and the outer wall of the clamping block 12 is movably connected with the rotating shaft 13.

[0030] In this embodiment, the horizontal interface of the clamping fastener 12 is triangular, and a round convex body is provided at one end of the clamping fastener 12.

[0031] In this embodiment, the structure of the mounting block 8 is L-shaped, and the mounting block 8 is welded to the inner wall of the second workpiece 3 .

[0032] In this embodiment, the movable groove 7 is an arc-shaped structure, and the movable groove 7 and the clamping fastener 12 fit each other.

[0033] In this embodiment, a docking groove 18 is provided on the outer wall of the first workpiece 1 on the side that is in contact with the second workpiece 3 , and a docking block 19 is provided on the outer wall of the second workpiece 3 .

[0034] In this embodiment, the docking groove 18 is an annular groove structure, and the docking groove 18 and the docking block 19 fit together.

[0035] Specific as Figure 3 , Figure 4 and Figure 6As shown, when this structure is used, the ports of the first workpiece 1 and the second workpiece 3 are docked through the docking groove 18 and the docking block 19, and the electric cylinder 9 is started. The output end of the electric cylinder 9 is extended to push the limit block 11 to slide and translate on the inner wall of the limit groove 17. Since the clamping fastener 12 is movably connected with the rotating shaft 13, the clamping fastener 12 rotates outward with the rotating shaft 13 as the axis. When the clamping fastener 12 rotates, the circular convexity set at the front end of the clamping fastener 12 will be clamped in the clamping groove 15, and at the same time, the circular convexity will press the inner wall of the first workpiece 1 inward, so that the first workpiece 1 and the second workpiece 3 are clamped and connected. This structure is convenient for connecting and fixing between tooling and is easy to disassemble.

[0036] Example 2: A second flange 4 is fixedly installed on the outer wall of the second workpiece 3 close to the first workpiece 1. The outer diameters of the first flange 2 and the second flange 4 are the same. The outer walls of the first flange 2 and the second flange 4 are symmetrically provided with threaded holes 6. The first flange 2 and the second flange 4 are connected and fixed by nuts 5.

[0037] In this embodiment, the outer wall of the nut 5 is provided with an external thread, and the inner wall of the threaded hole 6 is provided with an internal thread matching the external thread.

[0038] In this embodiment, the outer wall of the first workpiece 1 is provided with a slide groove 14 , and the inner wall of the first flange 2 is evenly provided with sliding blocks 16 .

[0039] In this embodiment, the sliding block 16 is hemispherical, and the engaging groove 15 and the sliding block 16 match each other.

[0040] Specific as Figure 1 , Figure 2 and Figure 5 As shown, when this structure is used, after the first workpiece 1 and the second workpiece 3 are connected and fixed, the outer walls of the first flange 2 and the second flange 4 will fit together. Since the first flange 2 is movably installed on the outer wall of the first workpiece 1 through the slider 16 and the slide groove 14, the first flange 2 is rotated to make the first flange 2 and the threaded hole 6 set on the outer wall of the second workpiece 3 communicate with each other, and the nut 5 is used to connect and fix them. Since the friction between the circular convex body set at the front end of the clamping fastener 12 and the outer wall of the clamping groove 15 is small, and the first flange 2 can rotate freely, the structure can be rotated at any angle and is easy to use.

[0041] Working principle: When in use, the first workpiece 1 and the second workpiece 3 are connected by the docking groove 18 and the docking block 19, and the electric cylinder 9 is started. The output end of the electric cylinder 9 is extended to push the limit block 11 to slide and translate on the inner wall of the limit groove 17. Since the clamping fastener 12 is movably connected with the rotating shaft 13, the clamping fastener 12 rotates outward with the rotating shaft 13 as the axis. When the clamping fastener 12 rotates, the round convex body set at the front end of the clamping fastener 12 will be clamped in the clamping groove 15, and the round convex body will press the inner wall of the first workpiece 1 inward, so that the first workpiece 1 and the second workpiece 3 are clamped and connected. When the first flange 2 and the second flange 4 are in contact with each other, the outer walls of the first flange 2 and the second flange 4 will fit together. Since the first flange 2 is movably installed on the outer wall of the first workpiece 1 through the slider 16 and the slide groove 14, the first flange 2 is rotated to connect the threaded holes 6 arranged on the outer walls of the first flange 2 and the second workpiece 3, and the nuts 5 are used to connect and fix them. Since the friction between the circular convex body arranged at the front end of the clamping fastener 12 and the outer wall of the clamping groove 15 is small, and the first flange 2 can rotate freely, the tooling flange can be self-lockingly connected to the workpiece through the clamping fastener 12 and can be rotated at will to adjust the angle, which is easy to use and easy to disassemble.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
