[0002] A battery pack water connector, used for cooling the battery, includes a base plate and a valve body mounted on the base plate. The valve body comprises two parallel and interconnected cylindrical bodies, both ends of which are open to form valve holes. A valve core mounting seat is located at the center of the valve hole. A central hole is formed on the valve core mounting seat, and a rod is fitted inside the central hole. The rod is coaxial with the valve hole and is installed from bottom to top during assembly, and is fixed at its upper end by a nut. The lower end of the rod extends radially outward to form the valve core body, and the valve core body and the rod form the valve core. To prevent the nut from loosening, a stop is provided at the end of the rod. This stop is used to limit the nut and prevent it from being vibrated and sliding outward, thus preventing loosening. The stop can be formed by extrusion (riveting). In the prior art, the battery pack water connector is assembled and enlarged manually, which is inefficient, inaccurate, and prone to errors. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a battery pack water connector valve core expansion device that can realize automatic assembly of valve body, with high assembly efficiency and good effect.

[0004] This utility model provides a battery pack water connector valve core expansion device, which includes:

[0005] A material placement assembly for placing the valve body of the battery pack water connector, the material placement assembly including a support column corresponding to the valve hole on the valve body, the support column being able to accommodate the valve hole and limit the valve body, the top of the support column contacting the lower end of the valve core inside the valve hole and supporting the valve core.

[0006] The clamping assembly includes clamping cylinders disposed on both sides of the material placement assembly and clamping blocks disposed at the output end of the clamping cylinders for clamping the valve body;

[0007] The hole-expanding mechanism includes a riveting press located directly above the material feeding assembly and a riveting head located at the output end of the riveting press and coaxial with the support column.

Detailed Implementation

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] See Figures 1-6 This utility model provides a battery pack water connector valve core expansion device, which includes a material feeding assembly 51, a material clamping assembly 52 and an expansion mechanism 53.

[0028] The material placement assembly 51 is used to place the valve body to be enlarged, the clamping assembly 52 is used to fix the valve body to ensure that the valve body will not move during the enlargement process, and the enlargement mechanism 53 is used to enlarge the hole at the upper end of the valve core, so that the edge of the hole deforms outward to form a stop. The stop is used to limit the nut outside the valve core to prevent the nut from loosening and improve the fixing reliability of the nut.

[0029] Specifically, the material placement assembly 51 is used to place the valve body of the battery pack water connector. The material placement assembly 51 includes a support column 513, which corresponds one-to-one with the valve hole on the valve body. The support column 513 is cylindrical, and its axis is perpendicular to the horizontal plane. The support column 513 can accommodate the valve hole, thereby realizing the limiting installation of the valve body. At the same time, the top of the support column 513 can contact the lower end of the valve core in the valve hole, thereby supporting the valve core and providing support force for the riveting of the upper end of the valve core.

[0030] During the reaming process, the top of the support column 513 contacts the lower end of the valve core and forms pressure. Over time, this will cause wear on the top surface of the support column 513, affecting the support accuracy and stability, reducing the reaming accuracy, and affecting product quality. Therefore, in this embodiment, a rivet pressure pad 5131 is provided on the top surface of the support column 513. The rivet pressure pad 5131 is used to contact the lower end of the valve core and is detachably installed on the top of the support column 513 by bolts. Specifically, the top surface of the support column 513 is concave to form a circular mounting hole, and the rivet pressure pad 5131 is disposed in the mounting hole. The top surface of the rivet pad 5131 forms a support surface for contacting the lower end of the valve core. A countersunk hole is provided in the center of the rivet pad 5131 for fixed connection with the support column 513 by bolts. Through the above structural settings, the rivet pad 5131 can be replaced periodically to maintain the support accuracy. The material of the rivet pad 5131 can be hard alloy, which has good wear resistance, thereby extending the service life of the support column 513 and ensuring the accuracy of the hole enlargement operation. This design not only improves work efficiency but also reduces maintenance costs, further improving the overall quality of the product.

[0031] The clamping assembly 52 is used to fix the valve body and includes clamping cylinders 521 symmetrically arranged on both sides of the feeding assembly 51. The clamping cylinders 521 are arranged horizontally, that is, the output shaft of the clamping cylinders 521 is perpendicular to the axis of the support column 513. A clamping block 522 is provided at the output end of the clamping cylinders 521. The clamping block 522 is used to clamp the valve body. A V-shaped or U-shaped groove is provided on the clamping surface of the clamping block 522 for clamping the cylinder of the valve body.

[0032] The hole-expanding mechanism 53 is used for hole expansion (riveting). It includes a riveting machine located directly above the material feeding assembly 51 and a riveting head 531 located at the output end of the riveting machine and coaxial with the support column 513. The riveting head 531 can be inserted into the hole at the top of the valve core and deform the open edge of the hole outward to form a stop for limiting the nut outside the valve core.

[0033] To improve the hole enlargement (riveting) effect and accuracy, and to avoid the impact on hole enlargement accuracy caused by using multiple riveting heads 531, the material placement assembly 51 in this application further includes a rotating seat 512. This rotating seat 512 is rotatable, and its rotation axis is perpendicular to the horizontal plane, i.e., parallel to the axis of the support column 513. Simultaneously, a driving device 514 is provided at the lower end of the rotating seat 512 to drive the rotating seat 512 to rotate. The aforementioned riveting head 531 is singular, and this riveting head 531 is located on the support column 513. On the rotation path, the distance between each support column 513 and the rotation axis of the rotating seat 512 is equal. By rotating the rotating seat 512, the support columns 513 on the rotating seat 512 can move sequentially to the direct below the riveting head 531 and coaxial with the riveting head 531, thereby sequentially enlarging the top of each valve core. This avoids the errors caused by using multiple riveting heads 531 and ensures the consistency and accuracy of each enlarging operation. In this way, not only is production efficiency improved, but the quality stability of the product is also guaranteed.

[0034] In this application, there are two sets of valve holes and valve cores. Therefore, there are two support columns 513, which are evenly distributed around the axis of the rotating seat 512. The rotating seat 512 is driven to rotate by the driving device 514, which can bring the two support columns 513 (valve cores) directly below the riveting head 531 in sequence for hole enlargement (riveting).

[0035] The aforementioned riveting head 531 includes a cylindrical body that can be inserted into the hole at the upper end of the valve core. The upper end of the cylindrical body extends outward in an arc shape to form a conical structure. The diameter of the conical structure is larger than the diameter of the hole. Therefore, during the insertion of the riveting head 531, the edge of the open end of the hole can be squeezed outward and deformed to form a stop. The stop contacts the end of the nut to limit the nut outside the valve core, prevent it from loosening, and ensure the long-term stable operation of the valve body.

[0036] In this embodiment, the driving device 514 is a rotary cylinder that can rotate 180 degrees, so that the two support columns 513 can move sequentially to the lower end of the riveting head 531 and perform hole enlargement operations in sequence. It has high operating accuracy. By using a single riveting head 531 for operation, it can ensure the accuracy and consistency of hole enlargement operations, and guarantee the reliability and stability of product quality.

[0037] For ease of assembly, this application also includes a mounting base 511, which is a plate-shaped structure. The material placement assembly 51 and the clamping assembly 52 are disposed on the upper surface of the mounting base 511, and the driving device 514 is disposed at the lower end of the mounting base 511.

[0038] To achieve automated loading and unloading and adapt it to the entire assembly system, this application also includes a material transfer robot II 54. The material transfer robot II 54 is used to transfer the valve body between the jig 9 of the conveying device and the material placement assembly 51. That is, it is used to move the valve body to be enlarged from the jig 9 of the conveying device to the support column 513 of the material placement assembly 51, or to move the valve body that has completed the enlargement operation from the material placement assembly 51 to the jig 9 of the conveying device, so as to enter the next process.

[0039] The material handling robot II 54 includes a clamping assembly, which includes grippers 544 for clamping the valve body and an elastic pressure rod 546 disposed between the two grippers 544. The elastic pressure rod 546 can elastically extend and retract, and the extension and retraction direction of the elastic pressure rod 546 is parallel to the axis of the support column 513. The end of the elastic pressure rod 546 can contact the upper end of the valve body, thereby causing the valve body to have a downward movement tendency, realizing reliable material release, especially improving the accuracy of placing the valve body on the placement assembly 51. That is, during placement, it can push the valve body downward and make the valve hole completely fit into the support column 513, improving the placement accuracy, thereby ensuring the hole expansion accuracy, avoiding errors in hole expansion accuracy caused by improper installation, and even preventing riveting operations. It provides a guarantee for the stable progress of hole expansion.

[0040] Specifically, the material handling robot II 54 includes a main horizontal slide 541 horizontally slidably mounted between the conveying device and the material placement assembly 51, a vertical slide 542 vertically slidably mounted on the main horizontal slide 541, a secondary horizontal slide horizontally slidably mounted on the vertical slide 542, and a clamping assembly mounted on the secondary horizontal slide. It is equipped with a first cylinder 5411 for driving the main horizontal slide 541 to slide horizontally, a second cylinder 5421 for driving the vertical slide 542 to rise and fall vertically, and a third cylinder for driving the secondary horizontal slide to slide horizontally. The sliding direction of the secondary horizontal slide is parallel to the sliding direction of the main horizontal slide 541, which increases the stroke of the clamping assembly, reduces the installation space of the main horizontal slide's track, and effectively controls the installation space of the entire assembly system. The clamping assembly includes a vertically arranged clamping cylinder 543, which is a hand... The pneumatic finger is equipped with grippers 544 at both output ends of the clamping cylinder 543 for clamping and grasping the valve body. Each gripper 544 includes a horizontally arranged clamping plate with grooves corresponding to the side wall of the valve body for gripping the valve body cylinder. A pressure rod hole 5441 for a flexible pressure rod 546 to pass through is located in the center of the clamping plate. A pressure rod fixing seat 545 is located on the side wall of the clamping cylinder 543 between the two grippers 544. A pressure rod and a spring with a downward tendency to move are vertically slidably mounted on the pressure rod fixing seat 545. The pressure rod and spring form a flexible pressure rod 546. A pressure block is provided at the lower end of the flexible pressure rod 546, which can contact the top of the valve body to push the valve body downwards during material release, thereby ensuring that the valve body can be accurately placed into the target position, improving the release accuracy and reliability.

[0041] This application also includes a detection sensor 56, which is tilted and faces the feeding assembly 51. It is used to detect the sealing ring on the valve body of the feeding assembly 51, and to determine whether the sealing ring is installed on the valve body, so as to avoid missing the sealing ring and cause product defects, and to ensure the quality of automatically assembled products.

[0042] This utility model relates to a battery pack water connector valve core reaming device. It features a support column and clamping assembly, enabling dual fixation of the valve body, improving fixation accuracy and stability, and ensuring precise reaming. The support column structure accommodates the valve hole, radially limiting the valve body, and simultaneously contacts the end of the valve core, providing effective support and preventing pressure transfer to the valve body during reaming, thus ensuring reaming accuracy and product quality. The rotating structure allows the support columns on the rotating base to move sequentially to directly below the riveting head, reaming the top of each valve core in turn. This avoids errors caused by using multiple riveting heads, ensuring consistency and accuracy in each reaming operation, improving production efficiency and guaranteeing product quality stability. The material handling robot enables automatic loading and unloading of valve bodies, facilitating integration with assembly systems, reducing manual operation, lowering labor intensity, and further optimizing the production process. An elastic pressure bar on the robot pushes the valve body downwards during unloading, ensuring the valve hole is fully fitted into the support column, improving placement accuracy and ensuring hole enlargement accuracy. This prevents errors caused by improper installation and guarantees stable hole enlargement. A detection sensor monitors the installation status of the sealing ring in real time, ensuring correct assembly, improving overall product reliability, and achieving an efficient and precise automated production process. This utility model's battery pack water connector valve core enlargement device enables automated hole enlargement of the battery pack water connector valve body, ensuring reliable installation of the nut on the valve body, preventing loosening, and achieving high hole enlargement accuracy and good product consistency.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
