Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The utility model provides a manual assembly jig of E shape jump ring, as shown in fig. 1-3, includes base 1, end plate 2 and kicking block 3, and end plate 2 sets up perpendicularly on base 1, and kicking block 3 is placed on base 1, and recess 21 that allows movable iron core to pass through is concavely established to end plate 2's upper surface. When the electromagnetic iron core fixing device is used, an electromagnetic coil is placed on the base 1, a fixed iron core is placed in the groove 21, the part of the fixed iron core, on which an E-shaped clamp spring is installed, protrudes out of the end face of the end plate 2, the top block 3 acts on the tail part of the electromagnetic coil, the spring of the electromagnetic coil acts on the first yoke and the end plate 2, and meanwhile the fixed iron core protrudes out of the end face of the end plate 2 through the top block 3. And then the E-shaped clamp spring can be clamped in through a tool.

In an embodiment, as shown in fig. 1-3, two first limiting portions 22 are extended from one end surface of the end plate 2, and a first limiting groove is formed between the two limiting portions 22, and the first limiting groove is in clearance fit with the electromagnetic coil. The electromagnetic coil is limited to shift to two sides through the first limiting groove. Preferably, the opposite side surfaces of the first limiting portion 22 are chamfered, so that the electromagnetic coil is clamped into the first limiting groove.

In the above embodiment, as shown in fig. 1 to 3, two second limiting portions 31 are extended from one end surface of the top block 3, which contacts the electromagnetic coil, and a second limiting groove is formed between the second limiting portions 31, and the second limiting groove is in clearance fit with the electromagnetic coil. The second limit groove is used for preventing the top block 3 from being offset to two sides after being matched with the electromagnetic coil. Preferably, the opposite sides of the second limiting portion 31 are chamfered, so that the electromagnetic coil is clamped into the second limiting groove.

In the above embodiment, as shown in fig. 1 to 3, the guide groove 4 is formed between the first limiting portion 22 and the base 1, and the guide groove 4 is in clearance fit with the second limiting portion 31. A third limiting part 32 is extended from one end surface of the top block 3, which is in contact with the electromagnetic coil, and the electromagnetic coil is limited to move up and down by the third limiting part 32. After the guide groove 4 is assembled with the second limiting part 31, the upward movement of the top block 3 is limited, and meanwhile, the upward movement of the electromagnetic coil is limited by the third limiting part 32, so that an assembly area for limiting the movement of the electromagnetic coil is formed through the structure; when the E-shaped clamp spring is assembled, only the base 1 is needed to be pressed or the base 1 is fixed on the table top. Preferably, the end of the second limiting portion 31 is provided with a chamfer to facilitate the insertion of the second limiting portion 31 into the guide groove 4.

In an embodiment, as shown in fig. 1-3, a clearance portion 23 is disposed at a corner of the first limiting portion 22 and the end plate 2. The rotation angle of the first yoke is avoided by the clearance portion 23.

In one embodiment, as shown in fig. 1-3, the length of the first limiting portion 22 is less than the length of the electromagnetic coil. So that the tail part of the electromagnetic coil protrudes out of the end part of the first limiting part 22, and the electromagnetic coil is conveniently taken out after assembly.

In one embodiment, as shown in fig. 1 to 3, the friction between the top block 3 and the base 1 is greater than the elastic force of the electromagnetic coil spring.
