[0002] With the rapid development of electronic products, hinges, as key components connecting two parts of a device, directly affect the overall quality and production efficiency of the product through their assembly precision and efficiency.

[0003] Traditional hinge assembly methods often rely on manual labor with the aid of fixtures. This approach suffers from low assembly precision, low efficiency, and high labor intensity. Especially when there are many hinge parts, each part requires the use of a different fixture for installation, resulting in a wide variety of fixtures and highly repetitive assembly steps, which seriously affects assembly efficiency and product quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 and Figure 2As shown, a hinge clamping assembly fixture includes a base 2 and a top cover 1. A first clamping mechanism and a second clamping mechanism are slidably disposed on the upper surface of the base 2. The first clamping mechanism includes two symmetrically arranged first clamping blocks 4 and a first slider 3 with a sliding trajectory along the symmetrical line of the first clamping blocks 4. The second clamping mechanism includes two symmetrically arranged second clamping blocks 7 and a second slider 8 with a sliding trajectory along the symmetrical line of the second clamping blocks 7. The first clamping mechanism and the second clamping mechanism respectively achieve symmetrical clamping of the workpiece through the first clamping blocks 4 and the second clamping blocks 7. The symmetrical design ensures uniform force distribution on the workpiece during assembly, avoiding positional shifts or deformations caused by unilateral force. The sliding trajectories of the first slider 3 and the second slider 8 coincide with the symmetry lines of the first clamping block 4 and the second clamping block 7, respectively, allowing the clamping mechanism to be flexibly adjusted according to the workpiece size and adapt to hinge components of different specifications. Precise positioning, achieved through sliding adjustment, allows the clamping mechanism to accurately control the workpiece position, ensuring accurate alignment of the hinge components during assembly and preventing assembly failures or quality defects due to positional deviations. The sliding adjustment mechanism, with the first slider 3 and the second slider 8 sliding on the upper surface of the base 2, allows the clamping mechanism to be quickly adjusted according to the size and shape of the workpiece. This flexibility makes the fixture suitable for various hinge components, improving its versatility. The symmetrical clamping design ensures uniform force distribution on the workpiece during clamping, reducing the risk of workpiece deformation or damage caused by unilateral force. Meanwhile, the sliding adjustment mechanism of the slider ensures the controllability of the clamping force, further improving the reliability of clamping; rapid positioning and clamping, through sliding adjustment and symmetrical clamping design, the fixture can quickly complete the positioning and clamping of the workpiece, reducing the adjustment time in the assembly process and improving production efficiency; reducing human error, the fixture's precise positioning and stable clamping function reduces errors caused by human operation, ensuring the consistency and stability of assembly quality.

[0019] like Figure 2 As shown, a third clamping mechanism 11 is provided on the outside of the first clamping mechanism; the third clamping mechanism 11 can operate independently and form a multi-station collaboration with the first clamping mechanism. For example, when assembling a hinge, the first clamping mechanism fixes the main structure, while the third clamping mechanism 11 can simultaneously clamp and position auxiliary components (such as springs and washers), realizing the parallel assembly of multiple components and significantly shortening the production cycle.

[0020] like Figure 2 As shown, a first spring 5 is provided between the first clamping mechanism and the third clamping mechanism 11; after clamping is completed, the first spring 5 can push the third clamping mechanism 11 back to its initial position, preparing for the next clamping. This automatic reset function simplifies the operation process and improves production efficiency.

[0021] like Figure 2As shown, four limiting blocks 6 are provided on the outer side of the third clamping mechanism 11. The four limiting blocks 6 can constrain the third clamping mechanism 11 from different angles to ensure that it always maintains a preset position during sliding or clamping. For example, when clamping irregular hinges, the limiting blocks 6 can prevent the third clamping mechanism 11 from shifting laterally due to uneven force, ensuring clamping accuracy. Through multi-point limiting, the limiting blocks 6 can eliminate positional deviations of the clamping mechanism caused by mechanical clearance or operational errors. For example, when assembling high-precision hinges, the limiting blocks 6 can ensure that the relative positional error between the third clamping mechanism 11 and the first clamping mechanism is controlled within the micrometer range.

[0022] like Figure 2 As shown, a stop 9 is provided on the outer side of the second clamping mechanism; when assembling the hinge, the stop 9 can limit the lateral displacement of the clamping mechanism, ensure that the workpiece and the reference surface of the fixture are in contact, and avoid assembly failure due to positional deviation.

[0023] like Figure 2 As shown, a second spring 10 is provided between the stop 9 and the second clamping mechanism. If the second clamping mechanism deviates in position due to manufacturing errors or irregular workpiece shape, the second spring 10 can push the clamping mechanism to finely adjust its position through elastic deformation, aligning it with the stop 9 or the workpiece. When clamping irregularly shaped hinges, the spring can automatically compensate for the lateral offset of the clamping mechanism, ensuring clamping accuracy.

[0024] like Figure 2 As shown, it also includes a cylinder, which is pneumatically connected to the slider; the cylinder drives the piston rod through air pressure, directly pushing or pulling the slider to move linearly along the guide rail. In the hinge assembly fixture, the cylinder can drive the slider to quickly approach or move away from the workpiece to complete the clamping or releasing action.

[0025] Working principle: The cylinder pushes the first slider 3 forward, the first clamping block 4 opens, and after the product is placed in, the cylinder retracts, and the first clamping block 4 clamps the product by spring force. The cylinder pushes the second slider 8 forward, the second clamping block 7 opens, and after the product is placed in, the cylinder retracts, and the second clamping block 7 clamps the product by spring force. The cylinder pushes out, pushing the third clamping mechanism 11 to the predetermined position, and accurately assembling the two sets of products; the limiting block 6 is used to lock the side of the third clamping mechanism 11.

[0026] In summary, this hinge clamping assembly fixture, through its three-way clamping mechanism and elastic compensation design, can adapt to hinge workpieces of different sizes and shapes, significantly improving assembly efficiency and yield. The combination of cylinder drive and sensor feedback enables rapid opening and closing and precise positioning of the fixture, reducing the single clamping cycle time to less than 1 second, making it suitable for high-speed production lines. The spring buffer and elastic limit design reduce mechanical wear, extend the fixture's service life, and simultaneously reduce noise pollution, improving the working environment.
