Description

Technical Field

[0001] This utility model belongs to the field of riveting, and specifically relates to a rivetless bridge-type riveting mechanism for antimagnetic shields. Background Technology

[0002] In the production of antimagnetic shields, traditional processes typically involve riveting or welding for connection. However, traditional welding leaves scars at the joints, requiring additional surface treatments such as grinding and polishing; while riveting may damage the plating or paint layer on the workpiece surface.

[0003] Meanwhile, traditional riveting joints have relatively low fatigue strength and are prone to loosening due to vibration; welding, on the other hand, may cause stress concentration due to hot working, which reduces the fatigue strength of the joint and also leads to insufficient connection strength.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a rivetless bridge-type riveting mechanism for anti-magnetic covers. Rivetless riveting is achieved by the cooperation of the upper and lower riveting blocks. Through the design of the elastic support component, elastic support is achieved during the riveting process, which ensures the accuracy and precision of riveting while preventing excessive pressure from damaging the equipment during the riveting process.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a rivetless bridge-type riveting mechanism for antimagnetic shields, comprising a base plate, a transverse positioning cylinder, a riveting placement block, a lower riveting block, several guide columns, a lower pressure cylinder mounting plate, a lower pressure cylinder, a lower pressure plate, and an upper riveting block; the transverse positioning cylinder is located beside the base plate; the output end of the transverse positioning cylinder is provided with a movable limiting block; the movable limiting block is located on the base plate; the base plate is also provided with a load-bearing block; the load-bearing block cooperates with the movable limiting block to complete the load-bearing during riveting; the riveting placement block is located between the load-bearing block and the lower pressure cylinder. The riveting lower block is mounted on the riveting placement block and slidably connected to the moving limit block; the riveting lower block is mounted on the riveting placement block; the riveting lower block is provided with several sets of elastic support components; the elastic support components are used to provide elastic support during the riveting process; the guide column is erected on the base plate; the pressure cylinder mounting plate is located between the upper ends of the guide column; the pressure cylinder is located on the pressure cylinder mounting plate; the pressure plate is located at the output end of the pressure cylinder and is guided by the guide column; the riveting upper block is located on the side of the pressure plate away from the pressure cylinder; the riveting upper block and the riveting lower block cooperate to complete the riveting.

[0007] Furthermore, the lateral positioning cylinder can precisely control the position of the moving limit block, thereby achieving accurate positioning of the riveted parts and ensuring that the riveted parts maintain an accurate positional relationship throughout the riveting process, reducing riveting quality problems caused by positional deviations; the load-bearing block provides a stable support foundation for the riveting process, and its cooperation with the moving limit block can effectively disperse the pressure generated during riveting, avoiding excessive local stress that could lead to device damage or deformation; the elastic support component set in the lower riveting block can provide a certain amount of elastic buffering during the riveting process, adapting to riveted parts of different thicknesses or shapes, and avoiding component damage or uneven riveting caused by hard contact; the guide column provides a stable guiding path for the movement of the lower pressure plate, making its vertical movement smoother and more linear;

[0008] Furthermore, the riveting lower block is provided with several riveting grooves; the elastic support component is disposed within the riveting grooves. The design of the riveting grooves ensures that each riveting operation is performed in the same position and under the same conditions, thereby guaranteeing the consistency of riveting quality and improving production stability.

[0009] Furthermore, the elastic support assembly includes a set of side plates and several sets of spring blocks; the side plates are disposed on both sides of the riveting groove; the spring blocks are respectively disposed on the sides and below the riveting groove where there are no side plates, and are located between the side plates to ensure elastic support during riveting. The spring blocks can provide uniform elastic support in multiple directions, ensuring a more uniform distribution of pressure during riveting and avoiding deformation or damage to the riveting point due to excessive local pressure.

[0010] Furthermore, several riveting pressure blocks are provided below the riveting upper block; the riveting pressure blocks are correspondingly arranged with the elastic support component, and the two cooperate to complete the riveting. The design of the riveting pressure blocks can ensure the precise positioning of the riveting point. Through cooperation with the elastic support component, the riveting pressure blocks can accurately apply the riveting force to the position that needs to be riveted, avoiding the offset or uneven force problems that may occur in traditional riveting methods.

[0011] Furthermore, the base plate is also provided with several limiting blocks; the limiting blocks are located between the load-bearing block and the movable limiting block. The limiting blocks provide precise positioning for the placement of the anti-magnetic cover, ensuring the accuracy of the riveting process.

[0012] Furthermore, a set of pneumatic couplings is also provided on both sides of the mounting plate of the downward-pressing cylinder. The pneumatic couplings ensure that the cylinder operates under appropriate pressure, avoiding damage or performance degradation of the cylinder due to excessively high or low pressure.

[0013] Furthermore, a control switch is also provided on the side of the base plate. The control switch provides stable control for this mechanism and improves the ease of operation.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:
