Description

Technical Field

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

[0002] In the hinge manufacturing process, the assembly stage is a crucial step in ensuring product quality and performance. Early hinge assembly relied heavily on manual fixation, which was not only inefficient but also lacked guaranteed positioning accuracy, significantly impacting the quality and consistency of hinge production. With the development of industrial automation, various fixing fixtures for hinge assembly emerged, aiming to improve the convenience and precision of fixing and assist automated assembly equipment. Initially, these fixtures were simple in structure, mostly consisting of single clamping or pressing structures. While they replaced manual fixing to some extent, they gradually revealed many shortcomings in the face of increasingly complex hinge product structures and the higher demands of automated production for space and precision, prompting continuous iteration and optimization of fixture structures.

[0003] Traditional jigs, when fixing products, do not adequately consider the working space requirements of automated robotic arms in their structural layout. When the robotic arm picks up and places products or performs assembly actions, it is prone to interference with the jig, limiting the improvement of automated production efficiency and making it difficult to adapt to modern, high-efficiency automated assembly lines. Furthermore, the jigs lack stability and flexibility: some jigs use rigid fixing methods and lack flexible fixing and adjustment mechanisms, resulting in poor adaptability to hinge products of different specifications and structures. During the fixing process, it is difficult to accurately control the clamping force, which can easily lead to product damage or insecure fixing, affecting assembly quality. The design of the various components of the jig (such as fixing mechanisms and positioning parts) is unreasonable, resulting in poor coordination of actions during product fixing and release, leading to cumbersome product installation and removal operations, extending the assembly cycle time, and reducing production efficiency.

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, a hinge assembly and fixing fixture includes a base 1 and a top cover 2 disposed on the base 1;

[0021] The oblique pushing mechanism 313 is mounted on the base 1 and includes a cylinder and a propulsion part. The cylinder is located at the bottom of the fixture and is used to drive the propulsion part to move obliquely.

[0022] The upper pressure plate 4, detachably connected to the end of the push section, is used to fix the hinge product. The base 1 is the basic support structure of the entire hinge assembly fixture, providing a stable mounting platform for the oblique push mechanism 313, the upper pressure plate 4, and other possible components. It ensures that each component maintains a relatively stable position during the use of the fixture and will not easily shift due to external forces or vibrations, thus guaranteeing the overall stability and reliability of the fixture. The base 1 can be fixedly connected to other equipment or worktables, providing a unified positioning reference for the assembly of the hinge product. This allows the fixture to maintain consistent assembly accuracy in different working environments, which is beneficial to improving the quality and consistency of hinge assembly. The cylinder in the oblique push mechanism 313 serves as a power source, providing power for the oblique movement of the push section. The cylinder is located at the bottom of the fixture. This layout design can make reasonable use of space, making the fixture structure more compact, and also facilitates connection and integration with other equipment or control systems. The push section moves obliquely under the drive of the cylinder, and this oblique push method has unique advantages. On the one hand, it can convert horizontal driving force into oblique thrust, thus adapting more flexibly to different assembly needs and spatial layouts. On the other hand, oblique thrust allows the upper pressure plate 4 to fix the hinge product at a suitable angle and in a suitable manner, ensuring that the product is subjected to uniform and stable pressure during assembly and improving the reliability of the fixation. The upper pressure plate 4 is detachably connected to the end of the thrusting part, and its main function is to directly fix the hinge product. Under the push of the oblique thrusting mechanism 313, the upper pressure plate 4 can accurately press on the hinge product, preventing the product from moving or shaking during assembly and ensuring the accuracy and quality of assembly. The detachable connection design between the upper pressure plate 4 and the end of the thrusting part provides high flexibility. The corresponding upper pressure plate 4 can be replaced according to different types and sizes of hinge products, enabling the fixture to adapt to various hinge assembly tasks of different specifications, improving the versatility and applicability of the fixture, and reducing production costs.

[0023] like Figure 2 As shown, the propulsion section of the inclined thrust mechanism 313 has an inclined surface 32, which forms a certain angle with the horizontal plane, for oblique propulsion under the drive of a cylinder; the cylinder usually provides a linear driving force, mostly in the horizontal or vertical direction. The design of the inclined surface 32 of the propulsion section can convert the horizontal or vertical driving force of the cylinder into an oblique thrust.

[0024] In one embodiment of this utility model, the inclined plane 32 of the propulsion part has an angle of 30°–60°. Hinge assembly fixtures typically require the coordinated operation of multiple components within a limited space. An inclined plane 32 angle of 30°–60° allows the propulsion part to make efficient use of the fixture's internal space during oblique movement. This avoids the propulsion part occupying too much space horizontally due to an excessively small angle, which could affect the installation and movement of other components; and also avoids the propulsion part occupying too much space vertically due to an excessively large angle, which could increase the overall height of the fixture and hinder integration with other equipment.

[0025] like Figure 2 As shown, the oblique pushing mechanism 313 also includes a fixed base 33, and a guide rod 34 is provided between the fixed base 33 and the pushing part; the guide rod 34 provides a precise track for the oblique movement of the pushing part. When the cylinder drives the pushing part to move obliquely, the pushing part will move along the axial direction of the guide rod 34, thereby ensuring that the pushing part can move along a predetermined oblique linear trajectory. Without the guidance of the guide rod 34, the pushing part may deviate or wobble during the movement, causing the upper pressure plate 4 to fail to accurately fix the hinge product, affecting the assembly accuracy.

[0026] Furthermore, a spring is fitted onto the guide rod 34. After the cylinder completes the work of driving the propulsion part to move obliquely to fix the hinge product, the propulsion part needs to return to its initial position for the next assembly operation. The spring has an elastic restoring force. When the cylinder retracts or the driving force disappears, the spring can release the stored elastic potential energy, pushing the propulsion part to automatically return to its initial position along the guide rod 34, achieving fast and accurate reset and improving the working efficiency of the fixture.

[0027] like Figure 2 As shown, a positioning block 5 is provided on the base 1, which is used to position the product. The positioning block 5 is designed according to the specific shape and size of the hinge product, and can accurately define the placement position of the product on the base 1. During the hinge assembly process, the fit between various components requires high precision. The positioning block 5 ensures that the product can be accurately placed in the predetermined position each time, so that the upper pressure plate 4 can accurately press on the corresponding part of the product, thereby ensuring the dimensional accuracy and performance of the hinge after assembly. Operators can quickly and conveniently place the hinge product on the positioning block 5 without spending a lot of time adjusting the product's position. This greatly shortens the product placement time and improves the efficiency of the entire assembly process. On automated production lines, the positioning block 5, in conjunction with automated equipment such as robotic arms, can achieve rapid and accurate product placement, further improving production efficiency.

[0028] Furthermore, in one embodiment of this invention, a sensor is also included to detect whether the product is placed in the correct position. The sensors used in this invention are all commercially available components, and they can accurately detect whether the hinge product is precisely placed on the positioning block 5 of the base 1. Only when the product is fully placed in the correct position can subsequent assembly processes begin normally. This avoids assembly errors caused by product positional deviations or incomplete placement, ensuring that all hinge components can properly cooperate, and improving assembly accuracy and quality.

[0029] Working Principle: When the fixture is in its initial state, the cylinder is in the retracted position. The propulsion part of the inclined push mechanism 313 is in its initial position under the action of the guide rod 34 and the spring (if present). The upper pressure plate 4 is detachably connected to the end of the propulsion part. At this time, the upper pressure plate 4 is in the open state, and the positioning block 5 on the base 1 is clearly visible. The sensor is in standby monitoring state. When placing the product, the operator places the hinge product on the positioning block 5 on the base 1. The positioning block 5 is designed according to the shape and size of the hinge product to accurately define the position of the product and ensure that the product is placed in the correct assembly position. The sensor for detecting whether the product is placed in place starts to work and detects whether the product is placed in place. The sensor can be a photoelectric sensor, proximity switch, etc. When it detects that the product has been correctly placed on the positioning block 5, it feeds back a signal to the control system. After receiving the signal from the sensor, the control system of the inclined push mechanism 313 starts the cylinder. The cylinder is placed at the bottom of the fixture and begins to extend the piston rod, driving the propulsion part of the inclined push mechanism 313 to move obliquely. The propulsion unit has an inclined surface 32, which forms a certain angle (30°–60°) with the horizontal plane. Under the push of the cylinder, the propulsion unit moves forward along the inclined surface 32, thus driving the upper pressure plate 4 to fix the product. Since the upper pressure plate 4 is detachably connected to the end of the propulsion unit, the oblique movement of the propulsion unit will cause the upper pressure plate 4 to move together. During the movement, the upper pressure plate 4 gradually approaches and finally presses against the hinge product, fixing the product on the base 1 and providing stable support for subsequent hinge assembly operations. During the movement of the propulsion unit, if the oblique pushing mechanism 313 includes a fixed base 33 and a guide rod 34, the guide rod 34 plays a role in guiding the movement direction of the propulsion unit, ensuring that the propulsion unit moves obliquely along a predetermined trajectory. Meanwhile, if a spring is fitted on the guide rod 34, the spring can provide a certain buffering force during the movement of the pushing part, making the action of the upper pressure plate 4 pressing the product more smoothly. Furthermore, when the cylinder retracts, the spring can help the pushing part quickly reset. After the product is fixed by the upper pressure plate 4, the hinge assembly operation can be performed, such as installing screws and riveting. After the product assembly is completed, the control system controls the cylinder to retract the piston rod, and the pushing part of the inclined push mechanism 313 retracts to its initial position along the inclined plane 32 under the pull of the cylinder. Since the upper pressure plate 4 is detachably connected to the end of the pushing part, the upper pressure plate 4 moves as the pushing part retracts, gradually loosening the pressure on the hinge product, and finally returning to the open state. The operator removes the assembled hinge product from the positioning block 5 on the base 1, completing one hinge assembly and fixing operation. At this time, the fixture returns to its initial state, awaiting the next operation.

[0030] In summary, this hinge assembly and fixing fixture, through the rational layout of the oblique pushing mechanism 313, the pushing part, and the upper pressure plate 4, effectively reserves movement space for the robot arm while fulfilling the product fixing function, avoiding interference with the robot arm's operation, adapting to automated assembly lines, and improving the smoothness and automation level of the production process. The use of a cylinder for oblique pushing, combined with the spring force of the upper pressure plate 4 itself, to press the product tightly allows for precise control of the fixing process. Simultaneously, the design of spring connectors and elastic buffer layers ensures good adaptability to hinge products of different specifications, guaranteeing firm fixing while preventing product damage and improving assembly quality. The sensor assembly monitors the product placement status and the pressing status of the upper pressure plate 4 in real time, promptly reporting any abnormalities, contributing to precise control and quality assurance in the automated production process, reducing human intervention errors, and improving the level of intelligent production.
