DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Embodiment 1

[0020] As Figures 1 - 3 shown, a riveting machine with rapid positioning proposed in this embodiment includes a frame 1, a base 2, a pressing mechanism and a limit mechanism.

[0021] The frame 1 is arranged on the base 2; a foot switch 9 is installed on the base 2, and the foot switch 9 is electrically connected to the controller 7. When the operator steps on the foot switch 9, the foot switch 9 feeds back a signal to the controller 7, and the controller 7 then controls the first hydraulic cylinder 5 to work. The setting of the foot switch 9 can avoid direct hand operation and improve work efficiency.

[0022] The pressing mechanism is installed at the top of the frame 1. The pressing mechanism includes a first hydraulic cylinder 5 and a pressing plate 6. The first hydraulic cylinder 5 is installed on the frame 1, and the pressing plate 6 is installed on the output shaft of the first hydraulic cylinder 5.

[0023] The limiting mechanism includes a first cylinder 3, a limiting component 4 and an elastic telescopic component. The first cylinder 3 is located directly below the downward pressing mechanism. The first cylinder 3 is installed on the frame 1. The bottom end of the limiting component 4 is slidably installed inside the first cylinder 3. The elastic telescopic component is installed inside the first cylinder 3 and its upper end is connected to the limiting component 4. The elastic telescopic component includes a second cylinder 10, a movable rod 11, a spring 12 and a limiting block 13. Among them, the second cylinder 10 is arranged inside the first cylinder 3. The movable rod 11 is connected to the limiting component 4. The bottom end of the movable rod 11 is movably arranged inside the second cylinder 10 and is connected to the limiting block 13. The spring 12 is arranged inside the second cylinder 10. When the first hydraulic cylinder 5 drives the pressing plate 6 to move downward, the pressing plate 6 first contacts the top end of the limiting component 4. Since the bottom end of the limiting component 4 is connected with an elastic telescopic component, the pressing plate 6 can drive the limiting component 4 to move downward during the downward pressing process. When driving the pressing plate 6 to reset upward, the limiting component 4 is driven to reset under the elastic force of the spring 12. The limiting component 4 includes a first limiting column 41, a frustum 43, a second limiting column 42 and a cone 44 arranged in sequence from bottom to top.

[0024] An infrared sensor is installed at the upper end of the frame 1. When the infrared sensor detects an obstacle below it, it immediately feeds back the signal to the controller 7. Before the obstacle is removed, the controller 7 will not control the first hydraulic cylinder 5 to work. Through the setting of the above structure, the equipment has an anti-pinch function and higher safety.

[0025] Insert the limiting component 4 into the riveting hole on the workpiece. The riveting hole is arranged with a clearance fit with the first limiting column 41. Then insert the limiting component 4 into the inner hole of the nut. The inner hole of the nut is arranged with a clearance fit with the second limiting column 42. At this time, the nut and the riveting hole are coaxially arranged. Because the upper end of the cone 44 is provided with a pointed head, the limiting component 4 can be easily inserted into the inner sides of the riveting hole and the nut hole, realizing the rapid positioning work between the nut and the workpiece. Subsequently, start the first hydraulic cylinder 5 to work to drive the pressing plate 6 to move downward, and the pressing plate 6 presses the nut into the screw hole.

[0026] Embodiment Two

[0027] As Figure 1 shown, a riveting machine with rapid positioning proposed in this embodiment, compared with Embodiment One, in this embodiment, a sleeve 8 is arranged on the base 2. The bottom end of the frame 1 is vertically slidably installed inside the sleeve 8. A second hydraulic cylinder for driving the frame 1 to lift is installed inside the sleeve 8. Through the arranged second hydraulic cylinder, the frame 1 can be driven to lift, and then the limiting mechanism and the downward pressing mechanism can be driven to rise synchronously, so as to facilitate the use by operators of different heights.

[0028] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the relevant art.
