Description

Technical Field

[0001] This utility model relates to the field of electronic product assembly technology, and in particular to a rotatable positioning upper and lower shell screw assembly fixture. Background Technology

[0002] In the assembly process of electronic products, it is often necessary to assemble the upper and lower shells and secure them with screws. Traditional methods mainly rely on manual operation: one hand holds the upper and lower shells down while the other hand tightens the screws. This method has the following drawbacks and shortcomings:

[0003] 1. Low assembly efficiency: Because operators need to manually keep the shell in place and tighten screws one by one, the work efficiency is low, especially when screws need to be tightened on all four sides of the product, requiring frequent movement of the workpiece or operators.

[0004] 2. Unstable assembly quality: Manual pressing of the upper and lower shells can easily lead to loose fit, resulting in gaps in the assembled product or screws not being fully in place, affecting product quality.

[0005] 3. High operator fatigue: Prolonged manual pressing and screwing can easily cause operator fatigue, which in turn affects assembly consistency.

[0006] 4. Lack of positioning and support mechanisms: The existing process lacks effective workpiece fixing and rotation auxiliary structures, which cannot meet the requirements of efficient and stable batch assembly.

[0007] In summary, existing assembly methods suffer from low efficiency, unstable quality, and high labor intensity, and there is an urgent need for an improved structure to enhance assembly efficiency and quality. Utility Model Content

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0026] Please see Figure 1-3 The embodiments of this utility model include:

[0027] A rotatable positioning upper and lower shell screw assembly fixture includes: a fixture base 1, a rotating platform 2, a rotating connecting shaft 3, a spring plunger 4, a rotating positioning hole 5, a fixed mounting block 6, a product limiting seat 7, a contour limiting groove 8, a quick clamp 9, a bracket 10, and a pressure block 11.

[0028] The upper end of the rotary connecting shaft is connected to the rotary platform, and the lower end is connected to the fixture base, allowing the rotary platform to rotate axially around the rotary connecting shaft on the fixture base. The fixture base has multiple rotary positioning holes. A spring plunger is radially positioned on the rotary platform, with its lower end extending downwards through the rotary platform to movably connect with the rotary positioning holes, thereby locking or unlocking the rotation of the rotary platform. The spring plunger can be a rotary (spring) plunger or a spring positioning pin commonly used in this field.

[0029] More preferably, the fixture base is provided with a groove for mounting the rotary connecting shaft.

[0030] More preferably, the rotating connecting shaft and the rotating platform are concentric.

[0031] Further preferably, the fixture base is provided with 4 rotating positioning holes at corresponding angles to ensure accurate and reliable rotational positioning.

[0032] The rotating platform is equipped with multiple fixed mounting blocks to form an assembly area. The product limiting seat is equipped with a contour limiting groove that matches the shape of the product to support the electronic product to be assembled. The bottom of the product limiting seat is equipped with a fixed mounting groove, which is movably connected to the fixed mounting block to install the product limiting seat on the rotating platform. Different product limiting seats can be replaced according to different products.

[0033] A further preferred embodiment is that the rotating platform and the fixed mounting block are an integrated structure.

[0034] In a further preferred embodiment, the mounting block and the product limit seat are also provided with locking screw holes to further secure the product limit seat by locking screws.

[0035] On the rotating platforms on both sides of the assembly area, there is a set of supports facing each other. Each support is equipped with a quick clamp. A pressure block is connected to the output end of the quick clamp, so that the pressure block swings up and down under the action of the quick clamp to press or release the product.

Tighten the screws on one side first. After that, lift / rotate the spring plunger to separate the spring plunger from the rotary positioning hole. When the rotating platform is rotated to the appropriate position, release / reverse rotate the spring plunger so that the lower end of the spring plunger extends into the rotary positioning hole at that station and continue to tighten the screws, thereby completing the screw fastening on all four sides one by one.

[0040] The beneficial effects of this utility model of a rotatable positioning upper and lower shell screw assembly fixture are:
