A drive coil is fixedly connected inside the housing. A sliding seat is slidably connected inside the housing and below the drive coil. A drive plate is fixedly connected to the top of the sliding seat. A mounting sleeve is fixedly connected to the center of the bottom of the sliding seat. A screw is threaded into the inside of the mounting sleeve. Guide rods are slidably connected inside the sliding seat and on both sides of the mounting sleeve. A return spring is fixedly connected to the outer wall of the guide rod and below the sliding seat. A return spring is fixedly connected to the bottom of the inner wall of the housing and corresponding to the guide rod. A baffle is slidably connected at the position, and a pull ring is fixedly connected to the outer wall of the baffle away from the guide rod. An indicator plate is slidably connected above the baffle. A scale plate is fixedly connected to the outer wall of the housing near the indicator plate. A punch is fixedly connected to the top of the screw. A terminal block is fixedly connected to the top of the housing. The base and the limiting plate are both made of ABS plastic. The connection between the conveyor belt, the electric push rod, the power plug, and the control panel is all electrical. The mounting bracket, the sliding seat, the mounting sleeve, the baffle, and the indicator plate are all made of ABS plastic. Two sets of mounting brackets and terminal blocks are provided.

[0008] As a preferred embodiment of the present invention, the drive plate is made of copper, the drive coil is electrically connected to the terminal block via a wire, and the screw and punch are both made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In this invention, an electromagnetic loading device for bolt interference installation of composite material plates is designed. The device utilizes an electromagnetic loading mechanism for bolt installation. A worker places the composite material plate on a conveyor belt, which moves the plate directly below the punch. The worker pulls a pull ring, which moves a baffle outward, removing the baffle from the housing. An indicator plate moves downward. When the downward distance of the indicator plate matches the bolt installation depth, the worker stops pulling out the baffle and places the bolt inside the punch. The punch holds the bolt. The worker then connects the terminal block to an external power source using a wire, allowing external alternating current to flow into the power source. The drive coil is inserted into the drive coil, generating an alternating magnetic field around it. Under the action of this alternating magnetic field, alternating eddy currents are induced on the surface of the drive plate that is in contact with the drive coil, which in turn generates an induced eddy current magnetic field. The magnetic field of the drive coil and the eddy current magnetic field generate opposing repulsive forces, pushing the sliding seat downwards. The sliding seat drives the punch downwards through the mounting sleeve, and the punch presses the bolt into the composite material plate. When the sliding seat moves to the baffle position, the baffle blocks the sliding seat, preventing it from continuing to drive the bolt downwards. The depth of the screw entering the composite material plate can be adjusted, solving the problem that existing electromagnetic loading devices cannot adjust the installation depth of the bolt.

[0021] For examples, please refer to Figure 1-3 The present invention provides a technical solution:

[0022] An electromagnetic loading device for bolt interference installation of composite material plates includes a base 1, an electromagnetic loading mechanism 2 is provided on the top of the base 1, a conveyor belt 3 is installed on the top of the base 1 and directly below the electromagnetic loading mechanism 2, a limit plate 4 is slidably connected to the top of the base 1 and on both sides of the conveyor belt 3, an electric push rod 5 is fixedly connected to the outer wall of the limit plate 4, a control panel 6 is installed on the left side of the base 1, and a power plug 7 is installed on the right side of the base 1.

[0023] The base 1 is made of ABS plastic, and the connection between the conveyor belt 3, the electric push rod 5, the power plug 7 and the control panel 6 is all electrical.

[0024] In this embodiment, reference Figure 2 and Figure 3The electromagnetic loading mechanism 2 includes a mounting bracket 201 fixedly connected to the top of the base 1. A housing 202 is fixedly connected to the outer wall of the mounting bracket 201. A drive coil 203 is fixedly connected inside the housing 202. A sliding seat 204 is slidably connected inside the housing 202 and below the drive coil 203. A drive plate 205 is fixedly connected to the top of the sliding seat 204. A mounting sleeve 206 is fixedly connected to the center of the bottom of the sliding seat 204. A screw 207 is threadedly connected inside the mounting sleeve 206. Guides are slidably connected inside the sliding seat 204 and on both sides of the mounting sleeve 206. A return spring 209 is fixedly connected to the outer wall of the guide rod 208 and below the sliding seat 204. A baffle 210 is slidably connected to the bottom of the inner wall of the housing 202 and at the corresponding position of the guide rod 208. A pull ring 211 is fixedly connected to the outer wall of the baffle 210 and at a position away from the guide rod 208. An indicator plate 212 is slidably connected to the top of the baffle 210. A scale plate 213 is fixedly connected to the outer wall of the housing 202 and at a position close to the indicator plate 212. A punch 214 is fixedly connected to the top of the screw 207. A terminal block 215 is fixedly connected to the top of the housing 202.

[0025] The mounting bracket 201, sliding seat 204, mounting sleeve 206, baffle 210, and indicator plate 212 are all made of ABS plastic. Two sets of mounting bracket 201 and terminals 215 are provided. The drive plate 205 is made of copper. The drive coil 203 is electrically connected to the terminals 215 via wires. The screw 207 and punch 214 are both made of stainless steel. The mounting sleeve 206, indicator plate 212, and baffle 210 all penetrate the housing 20. 2. Extending out of the housing 202, the baffle 210 is provided with multiple sets. A magnet is fixedly connected inside the punch 214. The baffle 210 has a U-shaped structure design, and the indicator plate 212 has an L-shaped structure design. The screw 207 passes through the mounting sleeve 206 and extends out of the mounting sleeve 206. When the worker pulls the pull ring 211, the pull ring 211 will drive the baffle 210 to move outward, pulling the baffle 210 out of the housing 202. The indicator plate 212 will move downward. When the indicator plate... When the downward movement of 212 matches the installation depth of the bolt, the worker stops pulling out the baffle 210 and places the bolt inside the punch 214. The punch 214 will attract the bolt. The worker uses a wire to connect the terminal 215 to an external power source. The external alternating current enters the drive coil 203, causing an alternating magnetic field to be generated around the drive coil 203. Under the action of the alternating magnetic field, alternating eddy currents will be induced on the surface of the drive plate 205 that is in contact with the drive coil 203, thereby generating an induced eddy current magnetic field. The magnetic field of the drive coil 203 and the eddy current magnetic field will generate opposite repulsive forces. The sliding seat 204 moves downward under the action of the repulsive force. The sliding seat 204 will drive the punch 214 to descend through the mounting sleeve 206. The punch 214 presses the bolt into the composite material plate. When the sliding seat 204 moves to the position of the baffle 210, the baffle 210 will block the sliding seat 204, and the sliding seat 204 will not be able to continue to drive the bolt downward.

[0026] The workflow of this invention is as follows: When the electromagnetic loading device designed for bolt interference installation of composite material plates is in operation, the worker places the composite material plate on the conveyor belt 3. The control panel 6 activates the electric push rod 5, which pushes the limiting plate 4 closer to the composite material plate. The control panel 6 then activates the conveyor belt 3, which moves the composite material plate directly below the punch 214. The limiting plate 4 prevents the composite material plate from shifting on the conveyor belt 3. The worker pulls the pull ring 211, which moves the baffle 210 outward, pulling it out of the housing 202. The indicator plate 212 moves downward. When the downward distance of the indicator plate 212 matches the installation depth of the bolt, the worker stops pulling out the baffle 210 and places the bolt inside the punch 214. The punch 214 holds the bolt. The worker then uses a wire to connect the terminal 215 to an external power source, which supplies an alternating current. Entering the drive coil 203, an alternating magnetic field is generated around the drive coil 203. Under the action of the alternating magnetic field, alternating eddy currents are induced on the surface of the drive plate 205 that is in contact with the drive coil 203, thereby generating an induced eddy current magnetic field. The magnetic field of the drive coil 203 and the eddy current magnetic field will generate opposite repulsive forces. Under the action of the repulsive force, the sliding seat 204 moves downward. The sliding seat 204 will drive the punch 214 to descend through the mounting sleeve 206. The punch 214 presses the bolt into the composite material plate. When the sliding seat 204 moves to the position of the baffle 210, the baffle 210 will block the sliding seat 204. The sliding seat 204 can no longer drive the bolt to move downward. The worker disconnects the wire between the terminal 215 and the external power supply. The magnetic field in the drive coil 203 and the drive plate 205 disappears. The return spring 209 will push the sliding seat 204 to move in the opposite direction. The sliding seat 204 will drive the punch 214 back to its original position.
