Description

Technical Field

[0001] This invention relates to the field of riveting tooling technology, and more specifically to a high-efficiency multi-station automatic riveting device. Background Technology

[0002] Riveting is a process that uses stamping to form rivet points to connect and fix two materials. Riveting can connect and fix two different materials without damaging the material surface.

[0091] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0092] When using this device, different workpieces that need to be riveted are classified into the same type and placed in the feeding bin 3. The raw materials are then fed onto the sorting table 5-2 through the feeding bin 3. The workpieces are then transferred to the unloading station through the sorting table 5-2. The workpieces are pushed down onto the stepper seat 4-3 through the pusher plate 7-7. The stepper seat 4-3 then passes through each sorting table 5-2 from one side in sequence, realizing the sequential stacking of each type of workpiece. Finally, the stacked workpieces are sent to the bottom of the stamping fixture 2 for stamping and riveting processing. After completion, the workpieces are unloaded.

[0093] The lower end of the loading hopper 3 rests against the upper surface of the separator 5-3. Lifting the knob 6-3 disengages the locking teeth 10 at the lower end of the knob 6-3 from the toothed ring 9. Then, rotating the knob 6-3 rotates the threaded sleeve 6-1, causing the threaded sleeve 6-1 to rotate and move on the threaded rod 6-2, thereby adjusting the height of the panel 5-4. This adjusts the distance between the upper surface of the panel 5-4 and the upper surface of the separator 5-3, ensuring that this distance is slightly greater than the thickness of the workpiece within the loading hopper 3. The workpiece falls from the loading bin 3 onto the panel 5-4. The electric rotary table 5-1 drives the distributing table 5-2 to rotate, which in turn rotates the panel 5-4, thus moving the individual workpiece from the lower end of the loading bin 3 to the unloading station. The push rod 7-4 pushes the pusher seat 7-3 to slide on the crossbeam 7-2. The pusher seat 7-3, through the guide sleeve 7-5 and guide rod 7-6, drives the pusher plate 7-7 to move. The pusher plate 7-7 slides against the panel 5-4, moving the panel 5-4... 4. The workpiece located at the unloading station is pushed onto the upper surface of the stepper seat 4-3. The spring 7-8 pushes the pusher plate 7-7 downward to abut against the panel 5-4, thus ensuring that the pusher plate 7-7 abuts against the panel 5-4 at different heights. The stepper seat 4-3 is mounted on the stepper slide rail 4-2, and the stepper push rod 4-6 drives the drive seat 4-7 to reciprocate. When the drive seat 4-7 moves to one side of the stamping fixture 2, that is, to the right, the drive on the drive seat 4-7... The moving pawl 4-8 engages the one-way pawl 4-4 on the front side of the stepper seat 4-3, thereby pushing the stepper seat 4-3 to the right. At this time, the one-way pawl 4-4 on the rear side of the stepper seat 4-3 slides on the limiting pawl 4-5. When the drive seat 4-7 moves to the left, the one-way pawl 4-4 on the rear side of the stepper seat 4-3 is engaged by the limiting pawl 4-5, and the drive pawl 4-8 slides on the one-way pawl 4-4 on the front side wall of the stepper seat 4-3, thereby realizing the one-way push of the stepper seat 4-3 to the right.

[0094] After the workpiece that has been riveted is sent out by the stepper seat 4-3, the finished part is removed from the stepper seat 4-3, the unloaded stepper seat 4-3 is placed on the positioning slide rail 8, and the one-way cleaving teeth 4-4 on the stepper seat 4-3 are respectively connected with the driving cleaving claw 4-8 and the limiting cleaving claw 4-5, so that the stepper seat 4-3 on the positioning slide rail 8 moves forward and enters the stepper slide rail 4-2;

[0095] When the threaded sleeve 6-1 is rotated by the knob 6-3, the threaded sleeve 6-1 is pushed against the inner wall teeth of the toothed ring 9 by the elastic plate 12, so that the threaded sleeve 6-1 is limited by the elastic plate 12 when rotating, and the minimum rotation angle of the threaded sleeve 6-1 is the angle of a single tooth of the toothed ring 9.

[0096] The technical advantages achieved by adopting the above technical solution are as follows:

[0097] 1. This device uses a stepper seat 4-3 with unidirectional motion to enable the sequential feeding of multiple workpieces in layers. Through the multi-station operation of the equipment, it can achieve the feeding and stamping / riveting of workpieces.

[0098] 2. This device improves the material distribution platform 5-2 below the feeding hopper 3. Multiple working areas are separated on the material distribution platform 5-2 by the partition frame 5-3, and an adjustable lifting panel 5-4 is set up, so that the feeding and transfer of individual workpieces can be carried out for different workpieces, realizing multi-station cooperative feeding of the equipment.

[0099] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
