Description

Technical Field

[0001] The utility model relates to the technical field of riveting devices, in particular to a breakpoint riveting device for an aluminum-plastic cover. Background Art

[0002] When the aluminum-plastic cover is riveted, the protruding tip in the middle of the plastic cover is melted by the high-temperature riveting rod end, and the melted plastic is pressed onto the edge of the hole in the aluminum cover, thereby making the plastic cover bite onto the aluminum cover.

[0003] The current aluminum-plastic cover riveting device usually positions the aluminum-plastic cover by the arc groove on the edge of the positioning plate below, and then inserts the riveting rod into the aluminum-plastic cover for hot riveting. After that, the positioning plate rotates, and the riveting rod revolves with the positioning plate until the set hot riveting time is reached to discharge the material. During the whole hot riveting rotation process, the aluminum-plastic cover is fixed by pressing down the riveting rod, and because the hot riveting process itself has a low pressure, when the aluminum-plastic cover contacts the annular baffle on the outer edge of the positioning plate, the aluminum-plastic cover is prone to relative movement or rolling, which reduces the quality of riveting. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the aluminum-plastic cover cannot be effectively fixed only by accommodating the aluminum-plastic cover through the arc-shaped notch at the edge of the positioning plate and pressing the aluminum-plastic cover down through the riveting rod.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a breakpoint riveting device for an aluminum-plastic cover, comprising a main rod and a sliding sleeve sleeved on the bottom end of the main rod, the riveting head at the bottom end of the main rod is located in the sliding sleeve, an annular positioning protrusion is coaxially arranged at the bottom end of the sliding sleeve, a spring is sleeved on the sliding sleeve, and both ends of the spring are respectively fixed on the sliding sleeve and the main rod.

[0006] Preferably, a connecting ring is fixedly sleeved on the main rod, a guide block is fixedly connected to the outer wall of the connecting ring, a guide groove is axially opened on the outer wall of the sliding sleeve, and the guide block is located in the guide groove.

[0007] Preferably, an inner fixed sleeve is fixedly provided on the inner side wall of the sliding sleeve, an annular cavity is provided between the inner fixed sleeve and the outer wall of the sliding sleeve, and the spring is located in the annular cavity.

[0008] Preferably, an annular fitting section is provided at the inner top of the sliding sleeve, and the fitting section fits with the outer wall of the main rod.

[0009] 1. The utility model provides a breakpoint riveting device for an aluminum-plastic cover, wherein a sliding sleeve is mounted on a main rod, and the main rod and the sliding sleeve are connected by a spring, and the sliding sleeve covers the riveting head. When the aluminum-plastic cover is riveted, the sliding sleeve is pressed down to compress the spring, and the positioning protrusion at the end of the sliding sleeve is matched with the inner wall of the aluminum-plastic cover to fix the aluminum-plastic cover and ensure the quality of the riveting.

[0010] 2. During the working process, the riveting head is not exposed, which ensures the safety of the work. The sliding sleeve covers the riveting head to reduce heat loss and ensure a stable working temperature of the riveting head. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0012] Figure 1 It is a structural schematic diagram of an embodiment of the utility model.

[0013] Figure 2 It is a schematic diagram of the internal structure of an embodiment of the utility model.

[0014] In the figure: 1. main rod; 2. sliding sleeve; 3. positioning protrusion; 4. guide groove; 5. guide block; 6. spring; 7. connecting ring; 8. internal fixing sleeve; 9. riveting head. DETAILED DESCRIPTION

[0015] like Figure 1 and Figure 2 As shown, the utility model provides an aluminum-plastic cover breakpoint riveting device, comprising a main rod 1 and a sliding sleeve 2 sleeved on the bottom end of the main rod 1, a riveting head 9 at the bottom end of the main rod 1 is located in the sliding sleeve 2, an annular positioning protrusion 3 is coaxially arranged at the bottom end of the sliding sleeve 2, a spring 6 is sleeved on the sliding sleeve 2, and two ends of the spring 6 are respectively fixed on the sliding sleeve 2 and the main rod 1.

[0016] The main rod 1 is connected above the positioning disk. During the rotation of the positioning disk, the aluminum-plastic cover enters the arc groove on the edge of the positioning disk. During the rotation of the positioning disk, the main rod 1 rotates with the positioning disk, and after rotating to a specific position, the main rod 1 falls, and the sliding sleeve 2 at the bottom end of the main rod 1 abuts against the aluminum-plastic cover. At this time, the positioning protrusion 3 is inserted into the aluminum-plastic cover, and the outer wall of the positioning protrusion 3 is in contact with the inner wall of the aluminum-plastic cover. In the process of the main rod 1 continuing to move downward, the spring 6 is compressed, and then the aluminum-plastic cover is pressed by the spring 6 to fix the aluminum-plastic cover. Finally, the riveting head 9 melts the raised tip in the middle of the plastic cover, and the melted tip is cooled through the annular groove on the inner side of the bottom end of the riveting head 9, and then the riveting ring formed by the tip bites into the circular hole in the middle of the aluminum cover to achieve the riveting of the aluminum-plastic cover.

[0017] like Figure 2 As shown, in order to ensure the stable sliding of the sliding sleeve 2 on the main rod 1, a connecting ring 7 is fixedly mounted on the main rod 1, and a guide block 5 is fixedly connected to the outer wall of the connecting ring 7. A guide groove 4 is axially provided on the outer wall of the sliding sleeve 2, and the guide block 5 is located in the guide groove 4. The guide block 5 connected to the main rod 1 is located in the guide groove 4 on the surface of the sliding sleeve 2, ensuring that the sliding sleeve 2 will not rotate during the movement, and then after the sliding sleeve 2 presses the aluminum-plastic cover, the aluminum-plastic cover will not directly rotate relative to the riveting head 9.

[0018] like Figure 2 As shown, in order to ensure the stability of the spring 6, an inner fixing sleeve 8 is fixedly arranged on the inner side wall of the sliding sleeve 2, and an annular cavity is arranged between the inner fixing sleeve 8 and the outer wall of the sliding sleeve 2, and the spring 6 is located in the annular cavity. By setting the annular cavity to accommodate the spring 6, the spring 6 is in a stable working area.

[0019] like Figure 1 and Figure 2 As shown. The top of the sliding sleeve 2 is provided with an annular fitting section, which fits with the outer wall of the main rod 1. By providing a longer fitting section and cooperating with the main rod 1, the sliding or displacement of the end of the sliding sleeve 2 away from the main rod 1 can be avoided, thereby ensuring the stability of the riveting work.
