Technical Field
[0001] This utility model relates to the field of magnetic ring clamping technology, specifically a magnetic ring clamping device. Background Technology
[0002] Magnetic rings are commonly used anti-interference components in electronic circuits. They have a good suppression effect on high-frequency noise. They are ring-shaped and belong to a type of magnetic conductor. They are generally made of ferrite material. During the production and processing of magnetic rings, magnetic wire needs to be wound around the outer wall of the magnetic ring.
[0003] The magnetic ring is fed into the machine through a conveying mechanism and then fixed by a clamping device. The wire is then wound onto the magnetic ring by a winding mechanism according to a certain pattern. In the prior art, in order to better clamp the magnetic ring, the clamping device usually sets the contact surface between the clamping device and the magnetic ring to an arc surface. However, since the outer arc will change accordingly when the size of the magnetic ring is different, the contact surface between the clamping device and the magnetic ring will also change, making the clamping effect of the clamping device unstable.

In order to better clamp the magnetic ring, the clamping device usually sets the contact surface between the clamping device and the magnetic ring as an arc surface. However, since the outer arc will change accordingly when the size of the magnetic ring is different, the contact surface between the clamping device and the magnetic ring will also change, making the clamping effect of the clamping device unstable.

[0028] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3This embodiment provides a technical solution: a magnetic ring clamping device, including a connecting base plate 1, a clamping part 2, and a driving part 3.

The clamping arms b208 slide to clamp and fix the magnetic ring. The driving part 3 is located inside the connecting base plate 1. A driven tooth a301 is rotatably arranged inside the connecting box 201. A driven tooth b302 is located at the bottom of the driven tooth a301. The driven tooth b302 rotates to drive the driven tooth a301 to rotate. A transmission tooth 303 is rotatably arranged at the bottom of the connecting base plate 1.
[0030] An active tooth 304 is rotatably mounted on the bottom of the connecting base plate 1. The active tooth 304 and the transmission tooth 303 are meshed together. A motor 305 is mounted on the top of the connecting base plate 1. The output end of the motor 305 is connected to the active tooth 304. The active tooth 304 can be rotated by the motor 305. After being driven by the transmission tooth 303, the driven tooth b302 can be rotated. The rotation of the driven tooth b302 can drive the driven tooth a301 to rotate, thereby causing the clamping arm a202 and the clamping arm b208, which are meshed with the driven tooth a301, to move and thus clamp and fix the magnetic ring.
[0031] Example 2: Please refer to Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a magnetic ring clamping device, including a clamping part 2, a clamping arm a202 and a clamping arm b208.
[0032] A rack a203 is provided on the side of the clamping arm a202. The rack a203 and the driven tooth a301 rotate. The rotation of the driven tooth a301 can drive the rack a203 to move, thereby driving the clamping arm a202 to move. A rack b209 is provided on the side of the clamping arm b208. The rack b209 and the driven tooth a301 rotate. The rotation of the driven tooth a301 can drive the rack b209 to move, thereby driving the clamping arm b208 to move. A clamping rod a204 is provided on the side of the clamping arm a202, and a clamping rod b210 is provided on the side of the clamping arm b208. There are two clamping rods a204 and two clamping rods b210, and they are covered with rubber sleeves on the outside. When the clamping arms a202 and b208 move, the clamping rods a204 and b210 can contact the outside of the magnetic ring and clamp it in place.
[0033] A sliding column a205 is provided on the side of the clamping arm a202, and a positioning rod a206 is provided on the side of the clamping arm a202. The sliding column a205 passes through the positioning rod a206 and is slidably connected to it. A spring a207 is nested outside the sliding column a205. The spring a207 is located between the sliding column a205 and the positioning rod a206. The positioning rod a206 can be pushed to slide on the sliding column a205 by the spring a207. A sliding column b211 is provided on the side of the clamping arm b208, and a positioning rod b212 is provided on the side of the clamping rod b210. The sliding column b211 passes through the positioning rod b212 and is slidably connected to it. A spring b213 is nested outside the sliding column b211 of the sliding column a205. The spring b213 is located between the sliding column a205 and the positioning rod a206. The positioning rod b212 can be pushed to slide on the sliding column b211 by the spring b213.
[0034] Working principle: First, when both clamping arms a202 and b208 are in the open state, positioning rod a206 will abut against positioning rod b212 and be located in the middle of clamping arms a202 and b208. Then, when fixing the magnetic ring, the magnetic ring is moved above positioning rods a206 and b212 and is fitted around them. The motor 305 drives the active gear 304 to rotate, which in turn drives the driven gear b302 to rotate through the transmission gear 303. The rotation of driven gear b302 drives driven gear a301 to rotate. The rotating driven gear a301 can drive rack a203 and rack b209 to move, thereby causing clamping arms a202 and b208 to move inward simultaneously. A clamping rod a204 is provided on the side of clamping arm a202.
[0035] Clamping rods b210 are provided on the side of clamping arm b208. Two clamping rods a204 and two clamping rods b210 are each provided, and both are covered with rubber sleeves. When clamping arms a202 and b208 move, clamping rods a204 and b210 can contact the outer side of the magnetic ring and clamp it in place. Positioning rods a206 and b212 located inside the magnetic ring are also moved by the displacement of clamping arms a202 and b208, causing positioning rods a206 and b212 to move as well. The positioning rods will contact the inner wall of the magnetic ring. Spring a207 pushes the positioning rod a206 to slide on the slide column a205, and spring b213 pushes the positioning rod b212 to slide on the slide column b211. This allows the positioning rods a206 and b212 to fit tightly against the inner wall of the magnetic ring. Together with the clamping rods a204 and b210, the magnetic ring is firmly fixed. Since the positioning rods a206 and b212 are slidable, the device can clamp and fix magnetic rings of various sizes.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
