Description

Technical Field

[0001] This utility model relates to the field of aluminum casting processing technology, specifically a quick-change device for press-fitting tooling. Background Technology

[0002] In the press-fitting production of aluminum casting assemblies, it is usually necessary to manufacture press-fitting fixtures for the assemblies. Due to the large number of assemblies produced in the factory, the press-fitting equipment often requires frequent fixture changes. Conventional press-fitting fixtures are assembled onto the equipment using multiple bolts. Workers need wrenches to loosen multiple bolts to remove the fixture, and then tighten more bolts to install the new fixture. If there are many assembly steps, this severely impacts the fixture changeover cycle time and increases the labor intensity of workers. This invention allows workers to quickly and easily change fixtures on automated press-fitting lines, effectively reducing the changeover cycle time and offering high versatility. Utility Model Content

[0003] In view of this, the present invention aims to provide a quick-change device for press-fitting tooling, which can facilitate workers to quickly complete the tooling change work on the automatic press-fitting line.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A quick-change tooling device for press fitting includes a tooling interface fixed to an automated press fitting line and a tooling assembly detachably mounted on the tooling interface. The tooling interface includes a mold base and a positioning sleeve interference-fitted into a hole in the mold base. The tooling assembly includes a tooling, a round pin and a diamond pin fixed to the tooling, quick-change handles located at both ends of the tooling, a spring for driving the quick-change handles to reset, and a limiting post for limiting the travel of the quick-change handles. The quick-change handles are provided with a horizontal circular groove and a lower oblong groove. One end of the spring is pre-placed in the circular groove of the quick-change handle, and the other end abuts against the circular groove of the tooling. The limiting post is pre-placed in the oblong groove of the quick-change handle and fixed in the slot of the tooling by fasteners, so that the quick-change handle can only move linearly along the slot of the tooling. The tooling assembly is positioned and connected to the positioning sleeve of the tooling interface by the round pin and the diamond pin, and locked by the engagement of the quick-change handle with the groove of the mold base. Compressing the quick-change handles can separate the tooling assembly from the tooling interface.

[0006] In some embodiments, the round pin and the diamond pin are respectively fixed to the tooling by bolt one; the limiting post is fixed to a special slot in the tooling by bolt two.

[0007] In some embodiments, the limiting post cooperates with the waist-shaped groove to limit the movement range of the quick-change chuck to between the outermost and innermost sides of the tooling.

[0008] In some embodiments, the spring, in its natural state, pushes the quick-change chuck out to the outermost side of the tooling.

[0009] In some embodiments, the tooling assembly includes a tooling integrated round pin, a diamond pin, a quick-change clamp, a spring, and a limit post. Attached Figure Description

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The following is for reference. Figures 1 to 6 The quick-change device for press-fitting tooling of this utility model is described in conjunction with the embodiments.

[0022] A quick-change device for press-fitting tooling includes a mold base 1, a positioning sleeve 2, a limiting post 3, a round pin 4, a quick-change handle 5, a spring 6, a tooling 7, a bolt 1 8, a bolt 2 9, and a diamond pin 10. Two positioning sleeves 2 are inserted into the mold base 1 through an interference fit. The mold base 1 with the positioning sleeves 2 is fixed to the press-fitting automatic line by bolts, forming the tooling interface of the press-fitting automatic line. The round pin 4 and the diamond pin 10 are fixed to the tooling 7 by bolt 8. One end of the spring 6 is pre-placed in the horizontal round groove of the quick-change handle 5, and the limiting post 3 is pre-placed in the waist-shaped groove on the lower side of the quick-change handle 5. Then, the quick-change handle 5 with the spring 6 and the limiting post 3 is pushed into the special groove of the tooling 7, so that the other end of the spring 6 is placed in the round groove of the tooling 7. The limiting post 3 is fixed in the special groove of the tooling 7 by bolt 9, thereby restricting the quick-change handle 5 to only move linearly in the special groove of the tooling 7. At this time, the tooling 7 with diamond pin 10, round pin 4, spring 6, limiting post 3 and quick-change handle 5 forms the tooling assembly. The limiting post 3 restricts the movement range of the quick-change hand 5. The spring 6 pushes the quick-change hand 5 to the outermost side of the fixture 7. When the quick-change hand 5 compresses the spring 6, it can move to the innermost side of the fixture 7.

[0023] In actual use, the operator presses the quick-change clamps 5 at both ends of the tooling assembly, aligns the round pins 4 and diamond pins 10 of the tooling assembly with the positioning sleeves 2 of the tooling interface, and moves them upwards until they engage with the installation interface. Then, the quick-change clamps 5 are released, and the quick-change clamps 5 on the tooling assembly engage with the grooves in the tooling interface mold base 1, thus completing the installation of the tooling assembly on the tooling interface. The quick-change clamps 5 are then compressed, and the tooling assembly is pulled downwards, thus completing the disassembly and separation of the tooling assembly from the tooling interface.

[0024] Compared with existing technologies, the quick-change device for press-fitting tooling of this utility model has the following advantages:

[0025] This utility model allows for the rapid installation of the tooling assembly onto the tooling interface by compressing the quick-change clamp 5. Releasing the quick-change clamp 5 secures the tooling assembly to the tooling interface. Then, compressing the quick-change clamp 5 allows for the rapid removal of the tooling assembly from the tooling interface, completing the disassembly and detachment of the tooling assembly. This effectively reduces the operator's labor intensity and the pace of tooling changeover. By simply adding specific pressing structures to the tooling 7, different parts can be pressed, demonstrating its strong versatility.

They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
