Description

Technical Field

[0001] This utility model relates to the technical field of filter housings, and in particular to a foot-wrapping fixture. Background Technology

[0002] After the filter housing is placed into the coil (also known as the magnetic core or magnetic ring), the copper wire on the coil needs to be wound around the pins on both sides of the housing. This operation is called the pin winding action. In the conventional pin winding structure, only the pin winding action is performed. However, the position of the housing cannot be stable, which makes the pin winding quality of the same batch inconsistent. Utility Model Content

[0003] One objective of this invention is to provide a foot-wrapping fixture that stabilizes the material shell on the fixture, ensuring the smooth progress of the foot-wrapping process, and facilitating the removal of the ejector pin, thereby improving the finished quality of the filter.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A foot-wrapping jig includes a jig body, a top cover, and a pin. The jig body has an upper cavity and a lower cavity in its middle. The lower cavity is larger than the upper cavity. A material shell is placed in the upper cavity. The pin is inserted into the jig body horizontally. The middle part of the pin passes through the lower cavity and presses against the material shell. Magnets are provided at both ends of the jig body. The top cover covers the upper cavity, and the two ends of the top cover are magnetically attracted to the magnets.

[0006] As a preferred technical solution, wire-locking blocks are installed on both sides of the main body of the fixture. Several wire-locking grooves are distributed along the length direction on the wire-locking blocks, and adhesive blocks are installed in the wire-locking grooves.

[0007] As a preferred technical solution, the wire clamping block is provided with a first locking hole, and the wire clamping block is fixed to the fixture body by a screw passing through the first locking hole and threaded connection.

[0008] As a preferred technical solution, the upper cover is provided with a second locking hole, and the upper cover is fixed to the fixture body by a screw passing through the second locking hole and threaded connection.

[0009] As a preferred technical solution, a side cover plate is formed in the middle of the top cover, and the side cover plate is snapped onto both sides of the coil of the material shell.

[0010] As a preferred technical solution, one end of the ejector pin is formed with a boss, and the boss is located on the outside of the fixture body.

[0011] The beneficial effects of this utility model are as follows: It provides a foot-winding fixture. When the filter housing is loaded, the back side is pressed laterally by the ejector pin to fix the housing in the middle of the fixture body. At the same time, the front side is fixed with a magnetic top cover, so that the copper wires on both sides of the housing can be clamped on the wire clamping blocks on both sides, which facilitates accurate foot winding and improves the quality of the filter housing.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 3 As shown in this embodiment, a foot-wrapping fixture includes a fixture body 1, an upper cover 2, and a pin 3. The fixture body 1 has an upper cavity 4 and a lower cavity 5 in the middle. The size of the lower cavity 5 is larger than that of the upper cavity 4. A material shell 13 is placed in the upper cavity 4. The pin 3 is inserted into the fixture body 1 in a horizontal direction. The middle part of the pin 3 passes through the lower cavity 5 and presses on the material shell 13. Magnets 6 are provided at both ends of the fixture body 1. The upper cover 2 covers the upper cavity 4, and the two ends of the upper cover 2 are magnetically attracted to the magnets 6.

[0020] When installing the housing 13, the fixture body 1 needs to be flipped over, and the housing 13 is placed into the larger lower cavity 5. The pins on both sides below the housing 13 are locked outwards on the sides of the lower cavity 5. The main body of the housing 13 is in the upper cavity 4. The ejector pin 3 is inserted from one side of the fixture body 1. When the ejector pin 3 passes through the lower cavity 5, it presses the housing 13 tightly into the upper cavity 4. Then, the fixture body 1 is flipped over again, and the upper cover 2 is placed on top of the fixture body 1. The upper cover 2 is attracted and fixed by the magnet 6 and pressed tightly on top of the housing 13. Then, the entire fixture body 1 is moved in the fixture moving structure and moved to the position around the foot.

[0021] Both sides of the fixture body 1 are equipped with wire clamping blocks 7. Several wire clamping grooves 8 are distributed along the length direction on the wire clamping blocks 7. Glue blocks are installed in the wire clamping grooves 8. Furthermore, the wire clamping blocks 7 are provided with first locking holes 9. The wire clamping blocks 7 are fixed to the fixture body 1 by the threaded connection after the screw passes through the first locking hole 9. The copper wire extending from the coil of the material shell 13 is clamped into the wire clamping groove 8. In order to prevent the copper wire from breaking, glue blocks are used to clamp it.

[0022] In addition, the upper cover 2 is provided with a second locking hole 10. The upper cover 2 is fixed to the fixture body 1 by the threaded connection after the screw passes through the second locking hole 10. Moreover, a side cover plate 11 is formed in the middle of the upper cover 2. The side cover plate 11 is snapped onto both sides of the coil of the material shell 13. After the magnet 6 attracts the upper cover 2, in order to ensure the fixation, the current position of the upper cover 2 can be locked, and the movement of the coil in the material shell 13 is restricted by the upper cover 2.

[0023] One end of the ejector pin 3 is formed with a boss 12, which is located on the outside of the fixture body 1. The boss 12 restricts the insertion position of the ejector pin 3 on the fixture body 1 and makes it easier to pull it out.

[0024] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
