Description

Technical Field

[0001] This utility model relates to the field of hinge assembly fixture technology, specifically a hinge extrusion assembly fixture. Background Technology

[0002] In the early stages of hinge assembly technology development, it relied mainly on manual assembly, which was inefficient and difficult to guarantee accuracy. With the development of industrial automation, simple jigs began to be used in hinge assembly, but their functions were relatively limited.

[0003] However, existing hinges are usually assembled manually with the aid of fixtures. Hinges have many parts, and each part usually requires the use of a fixture for installation. This results in a wide variety of fixtures, high repetition in some assembly steps, and high labor intensity. The repetitive operations and frequent changes of fixtures during the assembly process reduce assembly efficiency. Furthermore, manual assembly can lead to errors in part installation and rework due to human error, as well as a reliance on the accuracy and complexity of the fixtures. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hinge extrusion assembly fixture, which has the advantages of reducing the types of fixtures, reducing labor intensity, and improving assembly efficiency and accuracy. It solves the problems of existing hinge assembly fixtures having many types, high labor intensity, low assembly efficiency, and poor accuracy.

[0005] To achieve the aforementioned goals of reducing the types of fixtures, lowering labor intensity, and improving assembly efficiency and precision, this utility model provides the following technical solution: a hinge extrusion assembly fixture, comprising a base and an end cap, characterized in that: an upper clamping mechanism is provided on the lower surface of the end cap, comprising a detachably connected third side push mechanism and a fourth side push mechanism, the third side push mechanism being provided with a third pushing part, a third pushing block being installed inside the third pushing part, and a third clamping part being formed between the third pushing blocks; the fourth side push mechanism is correspondingly provided with a fourth pushing block, a fourth pushing part being provided outside the fourth pushing block, and each fourth pushing block being extruded to form a fourth clamping part; a lower clamping mechanism is provided above the base, comprising a first side push mechanism and a second side push mechanism fixed to the base, the first side push mechanism being provided with a first pushing part, a first clamping part being formed between the first pushing parts, the second side push mechanism being provided with a second pushing block, a second clamping part being formed between the second pushing blocks, and a second pushing part being provided on the side of the second side push mechanism.

[0010] Preferably, the fourth side-pushing mechanism is provided with a fourth stop block, and a fourth spring is provided between the fourth stop block and the fourth push block.

[0011] Preferably, the third pusher block and the fourth pusher block are linked together.

[0012] Compared with the prior art, the present invention provides a hinge extrusion assembly fixture, which has the following beneficial effects:

[0013] This hinge extrusion assembly fixture features a two-tiered clamping mechanism. The lower clamping mechanism holds springs, parts, and shafts, while the upper clamping mechanism holds parts and gears, enabling centralized clamping of various parts and reducing the number of fixture types.

Detailed Implementation

[0020] 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.

[0021] like Figures 1-5As shown, a hinge extrusion assembly fixture includes a base 1 and an end cap 2. The fixture is characterized in that: an upper clamping mechanism is provided on the lower surface of the end cap 2, including a detachably connected third side-pushing mechanism 5 and a fourth side-pushing mechanism 6. The third side-pushing mechanism 5 is provided with a third pushing part 51, and a third pushing block 52 is installed inside the third pushing part 51, forming a third clamping part between the third pushing blocks 52; the fourth side-pushing mechanism 6 is correspondingly provided with a fourth pushing block 62, and a fourth pushing part 61 is provided outside the fourth pushing block 62, with each fourth pushing block 62 extruded to form a fourth clamping part 65; a lower clamping mechanism is provided above the base 1, including a first side-pushing mechanism 3 and a second side-pushing mechanism 4 fixed to the base 1. The first side-pushing mechanism 3 is provided with a first pushing part 33, forming a first clamping part 31 between the first pushing parts 33; the second side-pushing mechanism 4 is provided with a second pushing block 43, forming a second clamping part 41 between the second pushing blocks 43, and a second pushing part 42 is provided on the side of the second side-pushing mechanism 4; the third side-pushing mechanism in the upper clamping mechanism... The push mechanism 5 and the fourth side push mechanism 6 are detachably connected. This modular design makes the maintenance and replacement of the fixture more convenient. When a side push mechanism malfunctions or needs to be upgraded, it can be replaced individually without replacing the entire fixture, thereby reducing maintenance costs and time. The third side push mechanism 5 and the fourth side push mechanism 6 form the third clamping part and the fourth clamping part 65 by pressing with the third push block 52 and the fourth push block 62, respectively. This design can ensure the precise clamping and positioning of the hinge parts during the assembly process. At the same time, the first side push mechanism 3 and the second side push mechanism 4 in the lower clamping mechanism also form clamping parts through corresponding push parts and push blocks, further improving the accuracy and efficiency of assembly. By setting multiple clamping parts (the third clamping part, the fourth clamping part 65, the first clamping part and the second clamping part 41), the fixture can clamp the hinge parts at multiple points during the assembly process, thereby enhancing the stability and reliability of clamping. This multi-point clamping design helps to reduce the movement or deflection of parts during the assembly process and improves the quality of assembly.

[0022] like Figure 5As shown, the fourth push block 62 is equipped with a chuck 66. The chuck 66 can penetrate deep into the slot or specific part of the component to form a stable clamping point, thereby ensuring that the component will not shift or loosen during assembly. This stable clamping action is crucial for improving assembly accuracy and product quality. The design of the chuck 66 allows the fourth push block 62 to more accurately position the component when clamping it, reducing assembly errors caused by inaccurate clamping. This is especially important for hinge products that require high-precision assembly, ensuring that each component is installed in the correct position. The shape and size of the chuck 66 can be customized according to the shape and size of different components, thereby adapting to various types of hinge assembly needs. This flexibility makes the fixture more widely applicable, reducing the cost of changing fixtures due to changes in component shape. The design of the chuck 66 allows components to be clamped and positioned more quickly during assembly, reducing assembly time. Meanwhile, the stable clamping action reduces the time required for readjustment due to loose parts, further improving assembly efficiency; through automated control and the precise clamping action of the 66 chucks, manual intervention in the assembly process can be reduced, labor intensity can be lowered, and assembly errors caused by human factors can be reduced.

[0023] like Figure 2 As shown, a first spring 32 is provided at the outer end of the first pushing part; the first spring 32 can automatically reset the first pushing part to its initial position after the first pushing part completes the clamping or pushing action; this automatic reset function simplifies the operation process, reduces manual intervention, and improves assembly efficiency.

[0024] like Figure 3 As shown, a second stop 44 is provided on the second side push mechanism 4, and a second spring 45 is provided between the second push block 43 and the second stop 44. The second spring 45 enables the second push block 43 to apply a certain elastic force when clamping the part, which ensures the stability of clamping and avoids damage to the part due to excessive clamping force.

[0025] Meanwhile, the elasticity of the spring also allows the second pusher 43 to automatically reset after completing the clamping action, preparing for the next clamping, simplifying the operation process and improving assembly efficiency.

[0026] like Figure 4 As shown, a third pushing block 54 is provided on the third side pushing mechanism 5, and a third spring 53 is provided between the third pushing blocks 54; the setting of the third spring 53 enables the third pushing block 54 to apply a uniform and stable clamping force during the clamping process; this elastic clamping force can be finely adjusted according to the size and shape of the part to ensure the stability of the clamping, while avoiding damage to the part due to excessive clamping force.

[0027] like Figure 5As shown, a fourth stop 63 is provided on the fourth side push mechanism 6, and a fourth spring 64 is provided between the fourth stop 63 and the fourth push block 62; in the hinge extrusion assembly fixture, it has the advantages and functions of realizing elastic clamping and automatic reset, improving the adaptability and flexibility of clamping, buffering clamping force to protect parts, enhancing the stability and reliability of clamping, reducing mechanical wear and extending service life, and simplifying the structure and reducing costs.

[0028] like Figure 4 and Figure 5 As shown, the third push block 52 and the fourth push block 62 are linked together. This linkage allows the third push block 52 and the fourth push block 62 to move synchronously or in a coordinated manner, reducing the time and operation steps required to control each push block individually. This synchronization significantly improves assembly efficiency and shortens the production cycle. The linkage ensures that the relative position and distance between the third push block 52 and the fourth push block 62 remain accurate during movement, thereby improving assembly precision. This is especially important for hinge products that require high-precision assembly, ensuring that each part is installed in the correct position and reducing assembly errors or product defects caused by positional deviations.

[0029] Working principle: All cylinders advance all the pushing parts, the fourth side pushing mechanism 6 opens to all sides, the third side pushing mechanism 5 moves closer to the center, the second side pushing mechanism 4 opens to both sides, and the first side pushing mechanism 3 moves closer to the center. The two shafts are installed on the first side pushing mechanism 3. After the part is placed, the cylinder retracts, and the spring drives the first side pushing mechanism 3 to reset, releasing the product. After the cylinder advances again, it clamps the part. At this time, the product spring is installed, the cylinder retracts, and the second side pushing mechanism 4 clamps the spring. Then, the part is installed according to the part installation steps. The part is then installed on the shaft. After the cylinder is released, the third side pushing mechanism 5 drives the part to move to both sides, pulling the shafts on both sides and increasing the distance between the two shafts. Finally, two meshing gears are installed to complete the first step of hinge assembly.

[0030] In summary, this hinge extrusion assembly fixture, through the arrangement of upper and lower clamping mechanisms, allows for the centralized clamping of various parts by the lower clamping mechanism for holding springs, parts, and shafts, while the upper clamping mechanism can hold parts and gears, thus reducing the variety of fixtures. Simultaneously, the first side-pushing mechanism 3, the second side-pushing mechanism 4, the third side-pushing mechanism 5, and the fourth side-pushing mechanism 6 enable automated clamping and positioning, reducing labor intensity. During assembly, a reasonable process arrangement reduces repetitive assembly steps, eliminating the need for frequent fixture changes and improving assembly efficiency.
