[0001] This application relates to the field of core-pulling riveting fixture technology, and in particular to a servo-driven translational feeding type door sill beam nut plate core-pulling riveting fixture. Background Technology

[0002] In the manufacturing process of passenger vehicles, the riveting of the sill beam nut plate is an important step. A sill beam nut plate core-pulling riveting fixture is typically used during the riveting operation.

[0003] In related technologies, traditional door sill beam nut plate core-pulling riveting fixtures rely heavily on manual feeding and positioning. Due to the small cross-section and 2000mm depth of the door sill beam's inner cavity, positioning the nut plate on the door sill beam is extremely difficult. Manual positioning is hard to guarantee accuracy, which can easily cause deviations in the nut plate's installation position and affect the riveting quality. Moreover, due to the special structure of the door sill beam, the riveting process has limited operating space, making construction difficult and resulting in low production efficiency.

[0004] Therefore, we propose a servo-driven translational feeding door sill beam nut plate core-pulling riveting fixture to solve the above problems. Utility Model Content

An electric feeding table 3 is slidably installed on the door sill plate translational conveying track 2. The electric feeding table 3 is used for horizontal linear conveying of door sill plates. A support frame 4 located on the right side of the door sill plate translational conveying track 2 is fixedly installed on the top of the platform 1. The support frame 4 is configured as two sets, and door sill beams 5 are placed on both sets of support frames 4. By cooperating with the door sill plate translational conveying track 2 and the electric feeding table 3, the door sill plate can be automatically conveyed horizontally in a straight line, replacing manual feeding, improving feeding efficiency and consistency, reducing manual operation errors, improving production efficiency, and reducing labor intensity. A door sill plate positioning main seat 8 located between the support frame 4 and the door sill plate translational conveying track 2 is fixedly installed on the top of the platform 1. A door sill plate positioning tail seat 9 is fixedly installed on the top right side of the platform 1.

[0024] In this embodiment, two sets of positioning mechanisms are provided on platform 1. The positioning mechanisms are used to clamp and position the sill beam 5. The positioning mechanisms include two sets of pressing components 6 and one set of clamping components 7. The clamping components 7 are located between the two sets of pressing components 6. The pressing components 6 include a first bracket 61, a first hinge seat 62, a pressing arm 63, a first electric telescopic rod 64, and a second hinge seat 65. The first bracket 61 is fixedly installed on the top of platform 1, the first hinge seat 62 is fixedly installed on the top of the first bracket 61, the pressing arm 63 is rotatably installed on the first hinge seat 62 via a pin, the first electric telescopic rod 64 is fixedly installed on the top of platform 1, and the second hinge seat 65 is fixedly installed on the output shaft end of the first electric telescopic rod 64. One end of the pressing arm 63 abuts against the upper surface of the sill beam 5, and the other end of the pressing arm 63 is rotatably connected to the second hinge seat 65 via a pin. The clamping components 7 include a second bracket 71. Electric telescopic rod 72 and clamping block 73, bracket 71 are fixedly installed on the top of platform 1, electric telescopic rod 72 is fixedly installed on the top of bracket 71, clamping block 73 is fixedly installed on the output shaft end of electric telescopic rod 72, pressing component 6 is used to apply downward pressure to clamp and position sill beam 5, clamping component 7 is used to apply horizontal pressure to clamp and position sill beam 5 in the lateral direction, thereby achieving reliable and stable clamping and positioning of sill beam 5; and, in conjunction with nut plate positioning main seat 8 and nut plate positioning tail seat 9 for positioning nut plate, it can ensure that sill beam 5 and nut plate are accurately positioned during riveting, improve riveting accuracy and quality, ensure the accuracy and stability of body structural component assembly, and thus solve the problems of small inner cavity cross section and long depth of 2000mm of sill beam 5, difficulty in nut plate positioning and difficulty in riveting process construction.

[0025] In this embodiment, a limit block 10 is fixedly installed on the top left side of the platform 1. The design of the limit block 10 can block and limit the leftward movement of the electric feeding table 3, and prevent the electric feeding table 3 from disengaging from the nut plate and moving along the conveying track 2.

[0026] In this embodiment, a nut leakage detection mechanism 11 is fixedly installed on the top of the platform 1. The number of nut leakage detection mechanisms 11 is set to two sets and symmetrically distributed. The nut leakage detection mechanism 11 includes a bracket 111, a vertical beam 112 and a nut leakage sensor 113. The bracket 111 is fixedly installed on the top of the platform 1, the vertical beam 112 is fixedly installed on the top of the bracket 111, and the nut leakage sensor 113 is installed and fixed on the vertical beam 112. A mounting hole is opened on one side of the vertical beam 112, and the nut leakage sensor 113 is fixedly installed in the mounting hole. The design of the nut leakage detection mechanism 11 can monitor whether the nut is missing in real time, avoid riveting defects caused by missing nuts, effectively ensure product quality, and reduce scrap rate.

[0027] In this embodiment, multiple support legs 12 are fixedly installed at the bottom of the platform 1. The multiple support legs 12 are symmetrically distributed in pairs. The design of the support legs 12 provides stable support for the platform 1, enabling it to withstand various external forces during operation and ensuring the normal operation of each component.

[0028] With the above structure, the servo translational feeding sill beam nut plate core-pulling riveting fixture provided in this application is used by first placing the two sill beams 5 on the corresponding support frame 4 respectively. Then, the electric telescopic rod 72 is extended and operated. The electric telescopic rod 72 drives the clamping block 73 to move horizontally and linearly until the clamping block 73 is pressed against the side of the sill beam 5. Then, the electric telescopic rod 72 is stopped. Then, the electric telescopic rod 64 is extended and operated to push the hinge seat 65 to rise, so that the pressure arm 63 rotates around the hinge seat 62. When one end of the pressure arm 63 presses down and tightly contacts the upper surface of the sill beam 5, the electric telescopic rod 64 is stopped. Thus, the precise and reliable clamping and positioning of the sill beam 5 is completed.

[0029] Next, place the nut plate on the electric feeding table 3 and control the electric feeding table 3 to slide on the nut plate translation conveying track 2. This will smoothly and accurately convey the nut plate to the position where it will be riveted to the sill beam 5. At this time, the nut plate is positioned by the nut plate positioning main seat 8 and the nut plate positioning tail seat 9 to ensure that the nut plate is accurately positioned at the riveting position.

[0030] During the translation and conveying of the nut plate, the nut leakage detection mechanism 11 plays a role. The nut leakage sensor 113 can sense whether the nut is present in real time. If a nut is missing, the nut leakage sensor 113 will transmit the detection signal to the external controller to issue an alarm, prompt the operator or automatically stop the equipment to prevent riveting defects and thus ensure the riveting quality.

[0031] After the positioning of the sill beam 5 and the nut plate is completed, the operator can use a blind rivet gun to insert the blind rivet into the pre-drilled holes in the nut plate and the sill beam 5. Then, the blind rivet gun applies tension to break the core rod and complete the riveting process.
