DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-4 , an automatic riveting machine for a rocker production line, comprising a frame 1, a lifting assembly 2 arranged on the frame 1, and a riveting machine body 3 fixedly installed on the lifting assembly 2, the frame 1 is symmetrically provided with guide rails 11, a slide plate 4 is slidably installed on the guide rails 11, a driving mechanism 12 corresponding to the slide plate 4 is arranged on the frame 1, a slot 41 is provided on the slide plate 4, a turntable 42 is rotatably installed in the slot 41, a plurality of slots 421 distributed in a ring array are provided on the turntable 42, a limiting mechanism 43 is arranged between the turntable 42 and the slot 41, a slide groove 44 is provided at one end of the slide plate 4, a slider 45 is slidably installed in the slide groove 44, and a support rod 5 adapted to the slot 421 is fixedly installed on the slider 45. The positions of the slots 421 of different sizes can be adjusted by rotating the turntable 42, so that the slots 421 directly below the rotary riveting machine body 3 can be adapted to the rocker, and the position of the strut 5 can be adjusted by cooperating with the slide groove 44 and the slider 45 to adapt to the use of rockers of different lengths.

[0025] Reference Figure 3The limiting mechanism 43 includes a spline key 431 fixedly mounted on the end of the rotating disk 42 away from the card slot 421 and a plurality of spline slots 432 arranged in a circular array in the slot 41 and adapted to the spline key 431. During the rotation of the rotating disk 42, the rotating disk 42 can be limited by the coordination of the spline key 431 and the spline slot 432, so that the card slot 421 can be used stably.

[0026] Reference Figure 2 The flower keypad 431 is made of rubber material, and the sizes of the plurality of slots 421 are all different, thus ensuring that the rotating disk 42 can rotate normally.

[0027] Reference Figure 3 A positioning mechanism 46 is symmetrically arranged between the slider 45 and the slide slot 44. The positioning mechanism 46 can be used to fix the position of the slider 45 and the support rod 5 so that the rocker can be placed.

[0028] Reference Figure 4 The positioning mechanism 46 includes a guide groove 461 provided in the slide groove 44 and a plurality of positioning grooves 462 provided in the slide groove 44 and distributed in a linear array and connected to the guide groove 461 at one end. The guide groove 461 allows the slider 45 to slide, and the positioning groove 462 can position the slider 45 so that it can be fixed for use.

[0029] Reference Figure 4 The slider 45 is symmetrically provided with a limit block 451 adapted to the guide groove 461 and the positioning groove 462. By using the limit block 451, the slider 45 can slide and be fixed through the positioning groove 462 and the guide groove 461.

[0030] Reference Figure 1 The driving mechanism 12 includes a cylinder 121 fixedly mounted on the frame 1 and a push plate 122 fixedly mounted on one end of the slide plate 4, and the telescopic end of the cylinder 121 is fixedly connected to the push plate 122. When the cylinder 121 is turned on, the slide plate 4 can be driven to slide along the guide rail 11 through the push plate 122, thereby driving the slide plate 4.

[0031] Reference Figure 4 A plurality of convex bumps are provided in the guide groove 461 and the positioning groove 462. The convex bumps increase the friction between the limit block 451 and the guide groove 461 and the positioning groove 462, making it more stable when used in a stationary state.

[0032] The specific working principle of the present invention is as follows:

[0033] First, the cylinder 121 can be opened to push the slide plate 4 to slide along the guide rail 11 through the push plate 122, so that the slide plate 4 moves out of the lower position of the rotary riveting machine body 3. According to the size of the rocker that needs to be processed, the turntable 42 can be rotated first, so that the size of the slot 421 located directly below the rotary riveting machine body 3 can match the size of the rocker. During the rotation of the turntable 42, the spline key 431 can rotate in the spline groove 432, and when it stops, the spline key 431 can enter the spline groove 432 to realize the rotation of the turntable. 42 is limited, and then the slider 45 can be pulled to drive the limit block 451 to slide along the positioning groove 462 into the guide groove 461, and the slider 45 can be pulled to change the position of the strut 5. After the position adjustment of the strut 5 is completed, the slider 45 can be released. At this time, the limit block 451 can enter the positioning groove 462 at the corresponding position to fix the slider 45, and then the remote rod processing component is placed on the slot 421 and the strut 5, and the slide plate 4 is reset by the cylinder 121 to start the riveting process.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
