Description

Technical Field

[0001] The present application relates to the technical field of assembly equipment, and in particular to an assembly device for a shell of an electronic receiver at a projectile head. Background Art

[0002] In modern industrial production, the assembly of the electronic receiver shell of the projectile head is a crucial link, which is directly related to the reliability and performance of the product; however, the existing assembly technology faces many challenges in achieving high precision and high efficiency; traditional assembly methods mainly rely on manual operation and simple mechanical assistance, which often seem to be incapable of handling complex structures and precision parts, resulting in the following major problems in the assembly process: Limited positioning effect: In the existing assembly process of the projectile head electronic receiver shell, the shell positioning usually requires the operator to achieve it through visual inspection and manual adjustment. This method lacks precise mechanical assistance. Due to the lack of a special positioning mechanism, it is difficult for the operator to ensure the precise alignment and stable fixation of the shell parts during the assembly process. This positioning method that relies on the operator's experience and skills may cause fluctuations in assembly accuracy, affect the quality of welding or connection, and thus have an adverse effect on the final performance of the product. Low operating efficiency: Existing assembly devices usually require a lot of manual intervention. From positioning, fixing to testing, each step requires the operator to make detailed adjustments, which not only increases labor intensity, but also reduces production efficiency, making it difficult to meet the needs of large-scale production. With labor costs rising, this inefficient assembly method not only increases the cost burden of enterprises, but also limits their ability to respond quickly to market changes. Imperfect quality inspection: After assembly, the inspection of the flatness and welding quality of the shell often relies on manual visual inspection or simple mechanical measurement. The accuracy and consistency of these methods are difficult to guarantee, which may lead to unstable product quality; In response to the above problems, the present application proposes an assembly device for the electronic receiver shell of the projectile head, aiming to overcome the limitations of traditional assembly technology and provide a more precise, efficient and reliable assembly solution to meet the modern manufacturing industry's continuous pursuit of high quality and high efficiency.

[0013] Compared with the prior art, the beneficial effects of this application are: (1) The device fits the shell body with the outer wall of the positioning block and utilizes the driving force of the third motor to drive the fourth bevel gear to rotate. The rotation of the fourth bevel gear can synchronously drive the four third bevel gears to rotate. The third bevel gear then drives the threaded rod to rotate. The rotation of the threaded rod causes the four clamping blocks to move accordingly, thereby clamping and fixing the outer wall of the shell body, ensuring the precise positioning of the shell body, and facilitating welding assembly. Furthermore, the third motor drives the second gear to rotate, so that the clamped and fixed shell body can be rotated and adjusted, thereby optimizing the direction and position of welding assembly, improving assembly efficiency and accuracy, realizing stable positioning and flexible adjustment of the shell body during welding, and optimizing the entire welding assembly process.

[0014] (2) When the shell welding assembly is completed, the arc-shaped surface of the shell comes into sliding contact with the detection wheel when it rotates, and the movement of the detection wheel is converted into linear motion. When unevenness appears at the joint of the shell surface, this irregularity will cause the contact pressure of the detection wheel to change, thereby driving the sliding rod connected to it to move. The movement of the sliding rod further causes the detection block to shift. This shift will affect the infrared sensor's reception of the reflected signal from the detection block. When it is detected that the unevenness causes the detection block to shift, making it impossible for the infrared sensor to receive the expected reflected signal, the system can determine that there is a quality problem at the shell joint. This detection mechanism utilizes the high sensitivity and non-contact measurement advantages of the infrared sensor, and can monitor the assembly quality in real time without affecting the shell splicing process. In this way, the device can ensure the flatness of the shell joint during the welding assembly process and improve the quality and reliability of the final product.

[0015] (3) The device drives the first bevel gear to rotate through the first motor, and the rotation of the bevel gear is transmitted to the second bevel gear through the mechanical linkage effect, thereby driving the lifting gear to rotate. The rotation of the lifting gear is converted into linear motion by meshing with the rack on one side of the column, thereby realizing the up and down movement of the lifting seat, thereby adjusting the assembly operation height, thereby enhancing the adjustability of the device. Furthermore, the second motor drives the third gear to rotate, and the rotation of the gear drives the second gear and the first gear to rotate through the mechanical linkage effect, thereby realizing the longitudinal angle adjustment of the semicircular gear, so that the orientation of the shell can be adjusted, thereby realizing the longitudinal angle adjustment of the shell, which provides convenience for the assembly operation of the shell.
