Technical Field

[0001] This utility model relates to the technical field of automatic feeding and spinning workstations for press-fit nuts, specifically to an automatic feeding and spinning workstation for press-fit nuts. Background Technology

[0002] The press-fit nut spinning workstation is a specialized piece of equipment that integrates automated feeding, precise positioning, and spinning riveting functions. It is mainly used to firmly connect press-fit nuts to metal sheets through mechanical spinning and is widely used in fields such as automobile manufacturing, aerospace, electronics, and medical devices where high connection strength and consistency are required.

[0003] Currently, most press-fit nut spinning workstations typically involve placing the sheet metal into a tooling fixture, which then secures the sheet metal. The nut is then placed in the fixture, and the machine is started to press the nut onto the sheet metal to form a strong connection. However, the sheet metal sizes processed in the factory vary, requiring different fixtures to be changed when processing different sizes of sheet metal. Traditional equipment uses multiple bolts for fixing the fixtures, making replacement cumbersome, and the bolts may be lost after disassembly, making it inconvenient to use. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] This utility model provides a technical solution: such as Figure 1 - Figure 4 As shown, in this embodiment, the automatic feeding and spinning workstation for press-fit nuts includes: a mounting frame 1, with multiple mounting boxes 6 on one side of the mounting frame 1, multiple T-shaped slide grooves 12 on one side of each mounting box 6, T-shaped sliders 11 slidably connected to the inner walls of each T-shaped slide groove 12, plate fixing platforms 10 fixedly connected to the upper ends of each T-shaped slider 11, multiple L-shaped fixing blocks 14 fixedly connected to one side of each T-shaped slider 11, a sliding strip 15 slidably connected to one side of the inner wall of the mounting box 6, multiple limiting blocks 16 fixedly connected to the lower ends of each sliding strip 15, and one side of each limiting block 16 being respectively disposed within each L-shaped fixing block 14, a threaded hole on one side of the mounting box 6, a fixing screw 18 threadedly connected to the threaded hole, one end of the fixing screw 18 being rotatably connected to one end of the sliding strip 15, and a rotating rod 17 fixedly connected to the other end of the fixing screw 18.

[0023] By rotating the rotating rod 17, the fixing screw 18 moves along the threaded hole on the mounting box 6. While moving, the fixing screw 18 pulls the sliding strip 15, causing the limiting block 16 and the L-shaped fixing block 14 to be misaligned. By pulling the plate fixing table 10, the plate fixing table 10 can be removed from the mounting box 6. This structure is simple and easy to operate, and the plate fixing table 10 can be quickly installed and disassembled, improving the convenience of using the equipment.

[0024] like Figure 3 As shown, guide bars 13 are fixedly connected to both sides of the lower end of the plate fixing platform 10. Both guide bars 13 slide in the upper guide groove of the mounting box 6. The guide bars 13 are used to limit the sliding direction of the plate fixing platform 10 when it is installed in the mounting box 6.

[0025] like Figure 1 and Figure 2 As shown, a workbench 2 is fixedly connected to the other side of the mounting frame 1. A drive motor 3 is fixedly installed in the middle of the lower end of the workbench 2. A rotating disk 5 is rotatably connected to the middle of the upper end of the workbench 2. The lower end of the rotating disk 5 is connected to the output end of the drive motor 3 through a shaft coupling. The upper end of the rotating disk 5 is fixedly connected to the lower end of multiple mounting boxes 6. The multiple mounting boxes 6 are evenly distributed on the upper end of the rotating disk 5.

[0026] By turning on the drive motor 3, the rotating disk 5 is rotated, which moves the finished plate under the pressure head 8 out and moves the unprocessed plate under the pressure head 8. The rotating disk 5 and multiple mounting boxes 6 work together to quickly load and unload plates, improving the production efficiency of the equipment.

[0027] It is important to note that the rotation angle of the drive motor 3 is determined by the number of plate fixing tables 10 on the rotating disk 5, ensuring that each plate fixing table 10 can move to the working position of the spinning equipment 7.

[0028] like Figure 2 As shown, multiple casters 9 are fixedly installed at the lower end of the rotating disk 5. The casters 9 are evenly distributed at the lower end of the rotating disk 5. The casters 9 are used to support the lower part of the rotating disk 5 and prevent the rotating disk 5 from deforming after long-term use.

[0029] like Figure 1 and Figure 2 As shown, both sides of the lower end of the workbench 2 are fixedly connected with reinforcing ribs 4. One side of each reinforcing rib 4 is fixedly connected to one side of the mounting frame 1. Through the structural design of the reinforcing ribs 4, the stability of the workbench 2 installed on the mounting frame 1 is improved.

[0030] like Figure 1As shown, a spinning device 7 is installed on one side of the upper end of the mounting frame 1. A pressure head 8 is fixedly installed on one end of the output rod of the spinning device 7. The spinning device 7 and the pressure head 8 cooperate to squeeze the plate and nut in the plate fixing table 10 together.

[0031] This utility model provides an automatic feeding and spinning workstation for press-fit nuts, the specific working principle of which is as follows:

[0032] When using the press-fit nut spinning workstation, first place the workpiece to be processed in the workpiece fixing table 10 below the press head 8, turn on the spinning equipment 7, and the press head 8 will press the nut into the workpiece. While the equipment is processing, the operator places the workpiece to be processed in other workpiece fixing tables 10 and fixes it. After processing and fixing are completed, turn on the drive motor 3, rotate the workpiece that was just fixed to the processing area of ​​the press head 8, and the processed workpiece will be rotated out. The equipment can be used for rapid processing and production. When different workpieces need to be processed, rotate the rotating rod 17, and the fixing screw 18 moves along the installation... The threaded hole on the box 6 moves, and the fixing screw 18 pulls the sliding bar 15 while moving, so that the limiting block 16 and the L-shaped fixing block 14 are misaligned. By pulling the plate fixing table 10, the plate fixing table 10 can be removed from the mounting box 6. After removal, another plate fixing table 10 is installed. The T-shaped slider 11 of the plate fixing table 10 is slid to the top of the T-shaped slide groove 12. The rotating rod 17 is rotated in the opposite direction, and the limiting block 16 slides the L-shaped fixing block 14 to fix the T-shaped slider 11. The replacement is completed. Repeating the above operation can enable the equipment to process different plates.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
