Description

Technical Field

[0001] The present invention mainly relates to the field of welding tooling, and in particular to a welding tooling for processing choke coils. Background Art

[0002] As a branch of inductor products, chokes are mainly divided into low-frequency chokes, high-frequency chokes and common-mode chokes. Their magnetic cores are either ring-shaped or rod-shaped. Their main structural feature is that the coil is wound around the outside of the magnetic core. When the finished product is manufactured, leads need to be welded at both ends of the coil.

[0003] When welding under the choke, conventional tooling is used, which can easily cause wear and extrusion of the coil outside the magnetic core, resulting in a reduction in the winding gap of the coil, affecting the heat dissipation of the coil close to the magnetic core. The extrusion of the coil can also cause the coil to stretch and deform, resulting in changes in the actual working parameters of the choke.

[0004] In order to realize the automation of choke welding and reduce the uncontrolled manual operation in the choke process, a welding tool for choke processing is proposed. The flexible tool is used to lock the welding position of the choke and simplify the welding process of the choke. Summary of the Invention

[0045] Refer to[[ID=2,7]] Figures 1-4 , a welding tooling for choke processing, including the following structures:

[0046] A positioning frame 1, an inclined rubber rod 2 is fixedly provided in the upper middle part of the positioning frame 1, and a vertical rubber rod 3 is fixedly provided at the top of the inclined rubber rod 2;

[0047] An airbag 4, the outside of the airbag 4 is adhesively connected to the middle part of the vertical rubber rod 3;

[0048] A connecting rod 5, the bottom of the connecting rod 5 is movably connected to a link plate 6, and the bottom of the link plate 6 is movably connected to a connection ring 7;

[0049] A connection frame 8, auxiliary rods 81 are fixedly provided at equal intervals on the outside of the connection frame 8, and the tops of the auxiliary rods 81 are movably connected to the outside of the link plate 6.

[0050] In this embodiment, asFigure 1 and Figure 2 As shown in Figure 2 , it further includes a base 9. Four fixing brackets 91 are fixedly arranged at equal intervals on the outer side of the base 9. The fixing brackets 91 are movably connected to the bottom end of the positioning bracket 1.

[0051] The cooperation of the base 9 and the fixing brackets 91 completes the installation of the positioning bracket 1. Among them, the base 9 provides installation support for the first telescopic rod 71 and the second telescopic rod 82, realizing the highly integrated design of the device.

[0052] In this embodiment, as Figure 1 and Figure 3 shown, a leaf spring 11 is fixedly arranged at the bottom of the positioning bracket 1. The outer side of the leaf spring 11 is fixedly connected to the inner side of the fixing bracket 91. A limit stop 12 is fixedly arranged in the middle of the positioning bracket 1. The top surface of the limit stop 12 abuts against the bottom end of the inclined rubber rod 2.

[0053] The use of the limit stop 12 prevents large-sized chokes from slipping off the inclined rubber rod 2. With the design and use of the leaf spring 11, the leaf spring 11 cooperates with the fixing bracket 91 to complete the installation support of the positioning bracket 1. According to the inner diameter size of the choke, the inclined rubber rod 2 on the positioning bracket 1 is designed and used to complete the positioning and clamping of the choke on the positioning bracket 1 and the protection of the coil on the choke from being pinched. The welding clamping and positioning of the choke are completed through the positioning bracket 1, the leaf spring 11, the fixing bracket 91 and the base 9.

[0054] In this embodiment, as Figure 1 and Figure 3 shown, the top end of the inclined rubber rod 2 deflects towards the axis of the base 9, and the top of the inclined rubber rod 2 is bonded to the bottom of the airbag 4.

[0055] The first telescopic rod 71 and the second telescopic rod 82 cooperate to work, changing the working positions of the connecting frame 8 and the connecting ring 7, realizing the adjustment of the working position of the connecting rod 5. At this time, the positioning bracket 1 deflects on the fixing bracket 91, and the inclined rubber rod 2 completes the clamping and positioning process on the middle part of the choke through the airbag 4.

[0056] In this clamping and positioning operation, the clamping tightness of the airbag 4 on the choke can be adjusted by the single telescopic adjustment of the second telescopic rod 82, realizing the non-destructive clamping protection of the choke.

[0057] In this embodiment, as Figure 1 and Figure 3 shown, the bottom end of the vertical rubber rod 3 is inserted into the top end of the connecting rod 5, and a limit protrusion is fixedly arranged on the outer side of the bottom end of the vertical rubber rod 3.

[0058] When welding and positioning and clamping a non - annular magnetic core choke coil, by adding a vertical rubber rod 3 on the top of the inclined rubber rod 2, the first telescopic rod 71 and the second telescopic rod 82 cooperate to change the working distance between the vertical rubber rods 3, complete the clamping and positioning process of the magnetic rod choke coil, and the setting of the limit protrusion avoids the magnetic rod choke coil from slipping off the vertical rubber rod 3.

[0059] When the inclined rubber rod 2 cooperates with the vertical rubber rod 3 to clamp the magnetic ring choke coil, the second telescopic rod 82 contracts, the connecting plate 6 deflects with the connection point between the connecting plate 6 and the connecting ring 7 as the fulcrum, and the connecting rod 5 drives the vertical rubber rod 3 to deflect towards the center of the base 9, completing the reduction of the working distance between the vertical rubber rods 3, which facilitates the user to pass the magnetic ring choke coil through the vertical rubber rods 3 without damage. Then the second telescopic rod 82 extends, and the vertical rubber rod 3 deflects towards the outside of the base 9, realizing the clamping and positioning of the magnetic ring choke coil by the cooperation of the vertical rubber rod 3 and the airbag 4.

[0060] In this embodiment, as Figure 1 and Figure 3 shown, the included angle between the inclined rubber rod 2 and the vertical rubber rod 3 is in the range of 110° - 155°, and the inclined rubber rod 2 and the vertical rubber rod 3 form a clamping part.

[0061] The inclined rubber rod 2 and the vertical rubber rod 3 cooperate, and the two structures are designed with an included angle, and the clamping and positioning of the magnetic ring choke coil can be completed at the included angle.

[0062] When the first telescopic rod 71 contracts, the connecting plate 6 deflects with the connection point between the connecting plate 6 and the connecting frame 8 as the center of the circle, completing the adjustment of shortening the working distance between the vertical rubber rods 3, which facilitates the magnetic ring choke coil to be placed at the included angle between the inclined rubber rod 2 and the vertical rubber rod 3. When the first telescopic rod 71 extends, the working distance between the vertical rubber rods 3 is adjusted. At this time, the positioning frame 1 deflects towards the outside of the base 9 on the fixed frame 91, realizing the clamping and positioning of the magnetic ring choke coil.

[0063] In this embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, a first telescopic rod 71 is fixedly provided in the middle of the connecting ring 7, and the bottom end of the first telescopic rod 71 is fixedly connected to the middle of the base 9.

[0064] The cooperative design of the connecting ring 7 and the first telescopic rod 71, and the cooperation of the connecting ring 7, the connecting plate 6 and the connecting rod 5 realize the adjustment of the working positions of the inclined rubber rod 2 and the vertical rubber rod 3, and the overall structure design is reasonable and convenient to use.

[0065] In this embodiment, as Figure 1 、 Figure 3 and Figure 4As shown, the bottom end of the auxiliary rod 81 is fixedly connected with a second telescopic rod 82, and the bottom end of the second telescopic rod 82 is fixedly connected with the top of the base 9.

[0066] The design and use of the connecting ring 7 and the auxiliary rod 81 enable the second telescopic rod 82 to adjust the working position of the connecting rod 5 through the connecting ring 7, the auxiliary rod 81 and the connecting plate 6, changing the working positions of the inclined rubber rod 2 and the vertical rubber rod 3. The dual-drive design of the first telescopic rod 71 and the second telescopic rod 82 realizes the multi-station clamping and positioning of the device and improves the working stability of the equipment.

[0067] In this embodiment,

[0068] The use of the limit stop 12 prevents large-sized chokes from slipping off the inclined rubber rod 2. The design and use of the leaf spring 11, and the leaf spring 11 cooperates with the fixed frame 91 to complete the installation and support of the positioning frame 1. According to the inner diameter size of the choke, the inclined rubber rod 2 on the positioning frame 1 is designed and used to complete the positioning and clamping of the choke on the positioning frame 1 and the protection of the coil on the choke from being pinched. The welding and clamping positioning of the choke are completed through the positioning frame 1, the leaf spring 11, the fixed frame 91 and the base 9.

[0069] The first telescopic rod 71 and the second telescopic rod 82 cooperate to change the working positions of the connecting frame 8 and the connecting ring 7, realizing the adjustment of the working position of the connecting rod 5. At this time, the positioning frame 1 deflects on the fixed frame 91, and the inclined rubber rod 2 clamps and positions the middle part of the choke through the airbag 4. In this clamping and positioning operation, the clamping tightness of the airbag 4 on the choke can be adjusted by the independent expansion and contraction of the second telescopic rod 82, realizing the non-destructive clamping protection of the choke.

[0070] When welding and positioning and clamping a non-circular core choke, by adding a vertical rubber rod 3 to the top of the inclined rubber rod 2, the first telescopic rod 71 and the second telescopic rod 82 cooperate to change the working distance between the vertical rubber rods 3, completing the clamping and positioning process of the magnetic rod type choke. The setting of the limit protrusion prevents the magnetic rod type choke from slipping off the vertical rubber rod 3.

[0071] When the inclined rubber rod 2 cooperates with the vertical rubber rod 3 to clamp a magnetic ring type choke, the second telescopic rod 82 contracts, and the connecting plate 6 deflects with the connection point between the connecting plate 6 and the connecting ring 7 as the fulcrum. The connecting rod 5 drives the vertical rubber rod 3 to deflect towards the center of the base 9, completing the reduction of the working distance between the vertical rubber rods 3, which facilitates the user to pass the magnetic ring type choke through the vertical rubber rod 3 without damage. The second telescopic rod 82 extends, and the vertical rubber rod 3 deflects towards the outside of the base 9, realizing the clamping and positioning of the magnetic ring type choke by the vertical rubber rod 3 cooperating with the airbag 4.

[0072] The first telescopic rod 71 contracts, and the connecting plate 6 deflects with the connection point between the connecting plate 6 and the connecting frame 8 as the center of the circle, completing the adjustment of shortening the working distance of the vertical rubber rod 3, facilitating the placement of the magnetic ring choke at the included angle between the inclined rubber rod 2 and the vertical rubber rod 3. The first telescopic rod 71 extends, completing the adjustment of the working distance of the vertical rubber rod 3. At this time, the positioning frame 1 deflects outward from the fixed frame 91 towards the base 9, realizing the clamping and positioning of the magnetic ring choke.
