[0003] A magnetic patch device is a device or tool specifically used to stick magnetic sheets to specific locations. In the application of sticking magnetic sheets to magnetic steel, the magnetic sheets need to be stuck to the side walls of the inner cavity of the magnetic steel. The shape of the magnetic steel itself is approximately cylindrical, so the shape of its inner wall is circular.

In order to simplify the steps of arranging the magnetic sheets in a ring shape, a magnetic sheet clamp structure of a magnetic patch device is proposed. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2A magnetic sheet clamp structure of a magnetic sheet patch device, comprising: a base 1, a first hydraulic slide 2 is arranged on the base 1, a clamp body 6 is fixedly mounted on the first hydraulic slide 2, a magnetic conductive ring 7 is arranged inside the clamp body 6, the clamp body 6 can be divided into two parts, one part has an L-shaped cross-section and is a long strip structure, and the other part also has an L-shaped cross-section, but presents an arc structure, the arc length of the arc structure is equal to one-fourth of the circumference of the circle where the arc is located, and the end face of the arc structure is a vertical plane, the contact surface between the clamp body 6 and the magnetic conductive ring 7 is an arc surface, and the L-shaped cross-section of the clamp body 6 constitutes a channel for the magnetic sheets to be arranged and entered, and the arranged magnetic sheets are pushed in by the feeding mechanism of the patch machine. There are two clamp bodies 6 in total, and the contact surfaces of the two clamp bodies 6 are vertical planes, so that the two clamp bodies 6 can form a semicircle when in contact, so that half of the magnetic sheets can be adsorbed when the magnetic sheets are fed, thereby improving efficiency.

[0017] The first hydraulic slide 2 is provided with a second hydraulic slide 4, and a connecting shaft 9 is provided on the second hydraulic slide 4. The second hydraulic slide 4 is movably connected to a push rod 3 through the connecting shaft 9. A telescopic strip 5 is fixedly installed at the end of the push rod 3. The end of the telescopic strip 5 away from the push rod 3 is fixedly connected to the hoop body 6. An auxiliary spring 8 is fixedly installed at the end of the push rod 3 away from the telescopic strip 5. The end of the auxiliary spring 8 away from the push rod 3 is fixedly connected to the second hydraulic slide 4. The auxiliary spring 8 contacts the magnetic sheet located on the long strip structure of the hoop body 6. A rectangular hole is opened through the hoop body 6. The rectangular hole is used to pass through the telescopic strip 5 and the push rod 3 to ensure that the established structure can stably and reasonably push the remaining magnetic sheets to the surface of the magnetic conductive ring 7, so as to realize the annular adsorption of the magnetic sheets on the magnetic conductive ring 7, so as to facilitate the subsequent installation of the magnetic sheets. Among them, the magnetic conductive ring 7 is installed on the placement machine and controlled and driven by the placement machine.

[0018] Working principle: in actual use, the magnetic sheets are arranged and fed, and the first hydraulic slide 2 pushes the clamp body 6 fixed thereon to slide on the base 1, so that the ends of the two clamp bodies 6 are in contact. At this time, the arc structure at the end of the clamp body 6 can clamp the magnetic ring 7, and the magnetic sheet pushed for feeding enters along the preset sliding direction on the clamp body 6. After the feeding of the magnetic sheets is completed, the second hydraulic slide 4 is started to slide toward the magnetic ring 7, wherein the push rod 3 moves on the second hydraulic slide 4 using the connecting shaft 9, and the two ends of the telescopic strip 5 are respectively fixedly connected to the push rod 3 and the clamp body 6, and at the same time, the end of the push rod 3 away from the telescopic strip 5 is connected to the second hydraulic slide 4 using the auxiliary spring 8. Therefore, when the second hydraulic slide 4 slides, the end of the push rod 3 connected to the telescopic strip 5 slides obliquely under the restriction of the telescopic strip 5 and the connecting shaft 9, and the telescopic strip 5 will push the magnetic sheet located on the non-arc surface of the clamp body 6 to the magnetic ring 7, so that several magnetic sheets are surrounded and adsorbed on the magnetic ring 7. At this time, the magnetic ring 7 is contacted with the magnetic steel through other structures of the magnetic steel magnetic sheet bonding machine, so that the magnetic sheets on the magnetic ring 7 can be adsorbed inside the magnetic steel, completing the magnetic steel magnetic sheet bonding. When the first hydraulic slide 2 and the second hydraulic slide 4 restore the entire device to the initial state, under the action of the auxiliary spring 8, the push rod 3 is synchronously restored to the horizontal state to facilitate the subsequent magnetic sheet loading.
