Existing hinge positioning fixtures are typically complex in structure, inconvenient to operate, and lack high positioning accuracy. Some fixtures rely solely on simple mechanical structures for positioning, failing to meet the demands of high-precision assembly; others, while achieving a degree of positioning, are cumbersome to operate during product placement and removal, impacting production efficiency. Furthermore, existing fixtures may damage products during positioning, affecting product quality. Utility Model Content

[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 Figures 1-3As shown, a hinge positioning fixture includes a base 1. At least one pair of inclined pushing mechanisms 2 are symmetrically arranged on the base 1. Each inclined pushing mechanism 2 includes a fixed seat 21 and a gripper 24 slidably connected to the fixed seat 21. A side pushing mechanism 3 is installed between each pair of inclined pushing mechanisms 2. The side pushing mechanism 3 includes a pushing block 31 and an inclined surface 32 for flipping the product. The base 1 is the basic support structure of the entire fixture, providing mounting positions for other components and ensuring the stability and reliability of the fixture during use. It bears the weight of all mechanisms and various forces generated during product positioning and assembly, preventing the fixture from shaking or shifting, and ensuring the accuracy of positioning and assembly. The fixed seat 21 provides a mounting base for the gripper 24, ensuring that the gripper 24 can be stably mounted on the base 1. It determines the initial position and basic direction of the movement trajectory of the gripper 24, so that the gripper 24 maintains the correct posture during the sliding process; the fixed base 21 is usually designed with a guide structure, such as a slide rail, to cooperate with the gripper 24, guide the gripper 24 to slide in a predetermined direction, ensure the accuracy and smoothness of the movement of the gripper 24, and thus achieve precise positioning function; the gripper 24 is the part that directly contacts the product, and can clamp or release the product by sliding on the fixed base 21. During fixture operation, the gripper 24 moves to the appropriate position as needed to fix the product inside the fixture, preventing displacement during assembly and ensuring positioning accuracy. The push block 31 is the power transmission component of the side-pushing mechanism 3. It receives external power (such as force provided by a cylinder or other drive device) and transmits this force to the inclined plane 32 and other related components, driving the side-pushing mechanism 3 to move as a whole and achieve lateral pushing of the product. The stroke of the push block 31 can control the pushing distance of the side-pushing mechanism 3, thereby precisely adjusting the position and degree of contact between the product's two sides and the inclined plane 32 according to the product's size and assembly requirements, ensuring that the product can be accurately flipped to the predetermined position. The inclined plane 32 is a key functional component of the side-pushing mechanism 3. When the push block 31 pushes the inclined plane 32 to contact the two sides of the product, due to the special shape of the inclined plane 32, the product will rotate along the inclined plane 32 under the action of force, achieving upward flipping of the product's two sides, so that the product's installation interface faces upward, facilitating subsequent assembly operations. This flipping function allows the product to be in a more suitable posture during assembly, improving assembly accuracy and efficiency.

[0019] like Figure 2As shown, a guide rod 23 is provided between the fixed base 21 and the gripper 24, and a first spring is sleeved on the guide rod 23. The guide rod 23 provides a precise guiding path for the gripper 24 to slide on the fixed base 21. During the movement, the gripper 24 is restricted by the guide rod 23 and can only move linearly along the axial direction of the guide rod 23. This avoids the gripper 24 from deviating, wobbling, or tilting during the sliding process, ensuring the straightness and accuracy of the gripper 24's movement. This allows the gripper 24 to accurately reach the predetermined position, achieving reliable clamping and positioning of the product. The first spring is sleeved on the guide rod 23. When the gripper 24 moves along the guide rod 23 under the action of external force, once the external force disappears, the elastic deformation of the first spring will cause the gripper 24 to automatically return to its initial position. After the fixture completes one product positioning and assembly operation, the force on the gripper 24 is released, and the elastic force of the first spring will cause the gripper 24 to quickly return to the initial state, preparing for the next product positioning, thus improving the operating efficiency and automation level of the fixture.

[0020] like Figure 3 As shown, four limiting blocks 33 are also provided on both sides of the side pushing mechanism 3. During the pushing process, the pushing block 31 and the inclined surface 32 and other components of the side pushing mechanism 3 need to have their movement distance precisely controlled to ensure that the product can be accurately flipped to the appropriate position. The limiting blocks 33 can limit the pushing stroke of the side pushing mechanism 3. When the pushing component moves to contact the limiting block 33, it can no longer move forward, thereby avoiding the product being squeezed and deformed or damaged due to excessive pushing, or the side pushing mechanism 3 itself being damaged due to excessive force.

[0021] like Figure 3 As shown, a second spring 34 is provided between the push block 31 and the limit block 33. After the side push mechanism 3 completes one push action, the push block 31 needs to return to its initial position for the next operation. The second spring 34 stores elastic potential energy during the compression of the push block 31. When the driving force disappears or reverses, the stored elastic potential energy is released, pushing the push block 31 to move back to its initial position, assisting the push block 31 to quickly and accurately reset, and improving the working efficiency of the fixture.

[0022] like Figure 2As shown, a first slide rail 22 is provided on the fixed base 21; the first slide rail 22 provides a precise track for the gripper 24 to slide on the fixed base 21. The gripper 24 moves linearly along the first slide rail 22, which can avoid deviation, rotation or shaking during the sliding process, ensuring that the gripper 24 always moves in the predetermined direction, thereby accurately reaching the target position and realizing reliable clamping and positioning of the product; the first slide rail 22 has high manufacturing precision and surface finish, which can reduce the friction and resistance fluctuations when the gripper 24 moves, making the movement of the gripper 24 more stable and smooth, thereby improving the accuracy of the movement and repeatability of the gripper 24, ensuring that the positioning of the product is accurate every time.

[0023] Furthermore, a second slide rail is fixed below the push block 31 on the base 1. When the side push mechanism 3 is working, the push block 31 moves along a specific direction to push the product to flip. The second slide rail provides a precise track for the push block 31, allowing it to move in a straight line only along the extension direction of the slide rail. This avoids deviation or skewness of the push block 31 during movement, ensuring the accuracy of the pushing direction. As a result, the force can be accurately transmitted to the product, achieving accurate flipping and positioning of the product.

[0024] In one embodiment of this utility model, a cylinder is provided below the base 1; the cylinder provides power for the sliding of the gripper 24 in the inclined pushing mechanism 2 on the fixed seat 21. Through the extension and retraction of the cylinder, the gripper 24 is driven to move along the first slide rail 22 on the fixed seat 21, realizing the opening and clamping action of the gripper 24, thereby positioning and fixing the hinge product placed in the fixture, ensuring that the product maintains a stable position during subsequent assembly; for the side pushing mechanism 3, the cylinder is the power source for the movement of the push block 31. When the piston rod of the cylinder extends, it pushes the push block 31 to move along the second slide rail on the base 1, thereby causing the push block 31 to push the inclined surface 32, so that the two sides of the product contact the inclined surface 32 and rotate under the action of the inclined surface 32, realizing the upward flipping of the two sides of the product, so that the installation interface of the product faces upward, facilitating the assembly operation.

[0025] Working principle: The cylinder of the inclined push mechanism 2 is extended by adjusting the cylinder, and the inclined push assembly opens the corresponding part; the cylinder of the side push mechanism 3 is retracted; the hinge product is placed on the corresponding placement area on the base 1. At this time, the cylinder of the inclined push mechanism 2 retracts, the first spring on the inclined push mechanism 2 returns to its original state, and the spring force causes the gripper 24 to position and clamp the product; according to the assembly requirements, the cylinder of the side push mechanism 3 is activated, the cylinder pushes the push block 31, and the two sides of the product contact the inclined surface 32 on the push block 31. Under the action of the inclined surface 32, the product rotates and the two sides flip upward. Rotate the machine so that the mounting interface faces upwards, facilitating subsequent assembly operations. After the product's posture is adjusted to the correct position, the hinge assembly operation is carried out. During the process, the sensor component monitors in real time whether the product is correctly placed and whether the actions of each mechanism are in place. If any abnormality occurs, it promptly feeds back to the external control system for adjustment or shutdown troubleshooting. After assembly, the cylinder of the side push mechanism 3 retracts, and the second spring 34 resets. The cylinder of the oblique push mechanism 2 extends again, opening the oblique side push assembly and removing the finished product. Afterward, the cylinder retracts, the first spring of the oblique push mechanism 2 resets, and it awaits the next loading operation.

[0026] In summary, this hinge positioning fixture, through the oblique push mechanism 2 utilizing the oblique push of a cylinder combined with the positioning of a first spring, and the synergistic effect of the side push mechanism 3, can achieve multi-directional, precise, and stable positioning of hinge products, effectively preventing product offset and ensuring processing and assembly accuracy. The side push mechanism 3 can use the inclined surface 32 to flip the two sides of the product upwards, so that the installation interface faces upwards, which greatly facilitates subsequent assembly operations, shortens assembly time, and improves production efficiency.
