[0016] The riveting device of the riveting machine according to an embodiment of the present utility model has at least the following beneficial effects:

[0017] This invention uses an electric push rod to extend and drive the connecting plate and the vertical rod to move downwards. As the vertical rod moves downwards, the inclined surface at the top of the rod can press the arc-shaped block.

[0018] This invention features a sloping surface and a flat surface at the top of the vertical rod near the movable part. When the stamping head bends the rivet pins on the touch piece, the arc-shaped block moves to the flat surface. Simultaneously, the vertical rod continues to move downwards, causing the pressing part at the top to press against the upper surface of the stamping head. At this point, the stamping head slides downwards along the guide rod and compresses the second spring. The pressing block bends the rivet pins on the touch piece downwards, thus better securing the bottom ring of the spring. This prevents safety hazards such as loosening or falling off during subsequent use, improving the overall performance and reliability of the product.

[0032] The following description, in conjunction with the accompanying drawings, describes a riveting device for a riveting machine according to an embodiment of the present invention.

[0033] Reference Figures 1 to 6 The present invention aims to provide an embodiment of a riveting device for a riveting machine.

[0034] This specific embodiment is a riveting device for a riveting machine, and its structural schematic diagram is shown below. Figures 1-6 As shown, the device includes a module plate 1, a fixing member 2, and a riveting position 3. The fixing member 2 has a cavity 4 inside. A movable member 5 is slidably inserted into the side of the fixing member 2 near the riveting position 3. A vertical rod 6 is inserted into the cavity 4. The top of the vertical rod 6 has an inclined surface 7 and a flat surface 8 near the movable member 5. An electric push rod 9 is fixedly connected to the lower surface of the module plate 1. A punch head 11 is slidably arranged on the movable member 5. A pressing member 10 corresponding to the punch head 11 is fixedly connected to the top of the vertical rod 6. The electric push rod 9 is used to drive the inclined surface 7 to press the movable member 5 so that the punch head 11 performs riveting.

[0035] like Figure 4 and Figure 5 As shown: In this embodiment, the movable component 5 includes a movable block 501. Two slide rods 502 are fixedly connected to the side of the movable block 501 away from the riveting position 3. The other end of the slide rod 502 passes through the inner wall of the cavity 4 and is fixedly connected to an arc-shaped block 503. The slide rod 502 is slidably connected to the fixing component 2. A first spring 504 is sleeved on the outer surface of the slide rod 502 and located between the arc-shaped block 503 and the inner wall of the cavity 4. In this way, the arc-shaped block 503 can drive the slide rod 502 and the movable block 501 to move and compress the first spring 504. During the movement, the movable block 501 can drive the stamping head 11 to move, bend the riveting pins on the touch piece and lock the spring.

[0036] like Figure 5 and Figure 6 As shown: In this embodiment, the interior of the movable block 501 is a hollow structure. A vertical elongated hole 505 is provided on the left side of the movable block 501. The other end of the elongated hole 505 is connected to the cavity 4. The punch head 11 is a long strip structure and is slidably connected inside the elongated hole 505. In this way, the punch head 11 can slide down along the elongated hole 505. The punch head 11 causes the rivet pins on the touch piece to bend downward, thereby better securing the spring.

[0037] like Figure 5 As shown: In this embodiment, two guide rods 506 are fixedly connected to the inner top wall of the movable block 501. The bottom end of the guide rod 506 passes through the stamping head 11 and is fixedly connected to the inner bottom wall of the movable block 501. The guide rod 506 is slidably connected to the stamping head 11. A second spring 507 is sleeved on the outer surface of the guide rod 506. The guide rod 506 guides the up and down movement of the stamping head 11 to avoid tilting and jamming. The second spring 507 is beneficial for the reset of the stamping head 11.

[0038] like Figure 4 and Figure 5As shown: In this embodiment, the pressing member 10 has an L-shaped structure, and the pressing head 11 is fixedly connected to the side of the riveting position 3 with a pressing block 1101; by setting the pressing block 1101, a step is formed on one side of the pressing head 11, so that it avoids the bottom ring of the riveting spring during the downward movement.

[0039] like Figure 1 and Figure 2 As shown: In this embodiment, there are three fasteners 2, which are circumferentially mounted on the upper surface of the module plate 1; this allows the three rivet pins on the touch sheet to be bent downwards at once, so as to better rivet and fix the touch sheet to the spring.

[0040] like Figure 2 and Figure 3 As shown: In this embodiment, the output end of the electric push rod 9 is fixedly connected to three connecting plates 901. The bottom end of the vertical rod 6 passes through the fixing member 2 and the module plate 1 and is fixedly connected to the connecting plate 901. The vertical rod 6 is slidably connected to the module plate 1 and the fixing member 2. When the electric push rod 9 is activated, it extends and drives the connecting plate 901 and the vertical rod 6 to move downward. During the downward movement of the vertical rod 6, the inclined surface 7 at the top can squeeze the movable member 5, thereby moving the punch head 11.

[0041] like Figure 1 and Figure 2 As shown: In this embodiment, the riveting position 3 includes a positioning groove 301 formed on the upper surface of the module plate 1. Multiple clearance grooves 302 are formed on the outer circumference of the positioning groove 301. The depth of the clearance grooves 302 is greater than the depth of the positioning groove 301. In use, the touch piece is placed into the positioning groove 301 at the riveting position 3 by an external robotic arm or slide rail, which can be positioned well. The outer clearance grooves 302 facilitate the removal of the touch piece and spring in the positioning groove 301 by a robotic arm.

[0042] Working principle: During use, the touch piece is placed at the riveting position 3 by an external robotic arm or slide rail. Then, another robotic arm moves the spring onto the touch piece. Next, the electric push rod 9 is activated to extend and drive the connecting plate 901 and the vertical rod 6 to move downward. During the downward movement of the vertical rod 6, the inclined surface 7 at the top can press the arc block 503. At this time, the arc block 503 drives the slide rod 502 and the movable block 501 to move and compress the first spring 504. During the movement of the movable block 501, the punch head 11 can move to bend the riveting pins on the touch piece and lock the spring. Then, the arc block 503 moves to the plane 8. The vertical rod 6 continues to move downward and causes the pressing part 10 at the top to press the upper surface of the punch head 11. At this time, the punch head 11 slides down along the guide rod 506 and compresses the second spring 507. The pressing block 1101 bends the riveting pins on the touch piece downward, thereby better locking the spring. Finally, the electric push rod 9 is reset, and the robotic arm removes the spring from the riveted touch piece.
