Description

Technical Field

[0001] This utility model relates to the field of rivet nut assembly and disassembly technology, specifically a quick rivet nut assembly and disassembly device. Background Technology

[0002] A rivet nut is a mechanical fastener used to connect and fix two or more components. It firmly joins the components together through riveting and is widely used in various industrial fields, such as automobile manufacturing, aerospace, building structures, and machinery manufacturing. However, disassembling a rivet nut after installation is very inconvenient. Although quick rivet nut disassembly and assembly devices have been proposed in the prior art, they still have some drawbacks. For example, the solution proposed in application number 202222225675.9, which involves adding a rivet nut disassembly and assembly device to the rivet nut gun body, can achieve the effect of quick rivet nut disassembly and assembly, but it is still very inconvenient to use overall. Since the step of disassembling the rivet nut is to disassemble it, the installation of the rivet nut is not performed. This means that under any circumstances, the operator must carry the entire device at the same time. Moreover, after the rivet nut has been ground, it does not provide a convenient function to remove the rivet nut. Therefore, we propose a quick rivet nut disassembly and assembly device. Utility Model Content

[0003] The purpose of this invention is to provide a quick assembly and disassembly device for rivets and nuts to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick-release device for rivet nuts includes a housing, a grinding wheel, and an electromagnet.

[0006] The outer wall of the outer shell is fitted with an anti-slip sleeve. A partition is provided on the right side of the inner cavity of the outer shell. An electric telescopic rod is provided at the center of the left side of the partition. A fixing plate is provided on the left side of the electric telescopic rod. A motor is provided at the center of the left side of the fixing plate. A motor shaft is provided on the left side of the motor. A transmission shaft is provided on the left side of the motor shaft. The transmission shaft extends through the center of the left side of the outer shell. A grinding wheel is provided on the left side of the transmission shaft.

[0007] A battery pack is located on the right side of the mounting plate. A mounting base is located at the center of the right side of the battery pack. An electromagnet is located on the right side of the mounting base. The electromagnet extends through the right side of the outer casing at the center of the right side. The battery pack and the electromagnet are electrically connected.

[0008] Furthermore, the inner wall of the anti-slip sleeve is provided with an adhesive layer, and the anti-slip sleeve is fixedly bonded to the outer wall of the outer shell through the adhesive layer.

[0009] Furthermore: the anti-slip sleeve is made of rubber, and rubber protrusions are evenly distributed on the surface of the anti-slip sleeve. The length of the anti-slip sleeve from left to right is greater than half the length of the outer shell from left to right.

[0010] Furthermore, a protective plate is provided around the left side of the outer wall of the outer casing, and the protective plate is a transparent protective plate.

[0011] Furthermore, the electromagnet is cylindrical, and a tapered contact head is provided on the right side of the electromagnet.

[0012] Furthermore, the electromagnet and the conical contact head are integrally molded structures.

[0013] Furthermore: slots are provided on the top and bottom right side of the outer casing, an outer protective shell matching the electromagnet is provided on the right side of the outer casing, and a locking block matching the slot is provided on the top and bottom left side of the outer protective shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This quick-release rivet nut device requires the operator to hold the outer casing while handling the device to improve stability. A non-slip sleeve is included to enhance safety and comfort. As the motor starts, the grinding wheel rotates, grinding the rivet nut until one end is flush with the surface of the part. After this step, the operator adjusts the casing and inserts an electromagnet into the flattened rivet nut. The electromagnet's magnetic force easily pulls the rivet nut out of the mounting hole. This series of operations not only improves work efficiency but also ensures a smooth and safe disassembly process. Attached Figure Description

Example

[0020] Please see Figure 1-2 This utility model provides a technical solution: a quick assembly and disassembly device for rivet nuts, including a housing 1, a grinding wheel 10, and an electromagnet 13;

[0021] The outer wall of the outer shell 1 is fitted with an anti-slip sleeve 2. The inner cavity of the outer shell 1 is provided with a partition 4 on the right side. An electric telescopic rod 5 is provided at the center of the left side of the partition 4. A fixing plate 6 is provided on the left side of the electric telescopic rod 5. A motor 7 is provided at the center of the left side of the fixing plate 6. A motor shaft 8 is provided on the left side of the motor 7. A transmission shaft 9 is provided on the left side of the motor shaft 8. The transmission shaft 9 extends through the center of the left side of the outer shell 1. A grinding wheel 10 is provided on the left side of the transmission shaft 9. The electric telescopic rod 5 can extend and retract, and through the cooperation of the fixing plate 6 and the motor 7, it can drive the grinding wheel 10 to extend and retract left and right, so as to be used in different situations. When the motor 7 is working, it will drive the transmission shaft 9 to rotate through the motor shaft 8. When the transmission shaft 9 rotates, it will drive the grinding wheel 10 to rotate. The rotating grinding wheel 10 can grind the rivet nut until it is completely flush with the surface of the part.

[0022] A battery pack 11 is provided on the right side of the fixing plate 6. A mounting base 12 is provided at the center of the right side of the battery pack 11. An electromagnet 13 is provided on the right side of the mounting base 12. The right side of the electromagnet 13 extends through and is located at the center of the right side of the outer casing 1. The battery pack 11 and the electromagnet 13 are electrically connected. When the electromagnet 13 is turned on, the end of the electromagnet 13 away from the outer casing 1 is inserted into the hole. In this way, the rivet nut can be removed from the mounting hole by the magnetic attraction of the electromagnet 13.

[0023] Preferably, the inner wall of the anti-slip sleeve 2 is provided with an adhesive layer, and the anti-slip sleeve 2 is fixedly adhered to the outer wall of the outer shell 1 through the adhesive layer. This arrangement allows the anti-slip sleeve 2 to be stably fitted onto the outer wall of the outer shell 1.
