Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically relating to a tooling for welding silver contacts. Background Technology

[0002] In electrical equipment manufacturing, silver contacts are widely used due to their excellent conductivity and corrosion resistance. However, silver contacts require welding during processing. To improve welding efficiency, tooling is needed to position and fix the silver contacts. However, existing welding tooling has certain drawbacks. For example, Chinese patent CN 210081042 U discloses a tooling for welding silver contacts, including a fixing mechanism and a limiting mechanism. The fixing mechanism includes a base and a support plate. The support plate is vertically fixed to the base, and a flat plate is fixedly connected to the top of the support plate. The flat plate is located above the base and has several through holes, each of which is threaded with a threaded rod. The limiting mechanism includes a holding block and a limiting plate for fixing to the base plate. The limiting plate has limiting grooves arranged to restrict the movement of the silver contacts. The cross-sectional area of ​​the holding block is smaller than that of the limiting grooves. Although this device positions the silver contacts, manual placement of the silver contacts is required during loading, making loading relatively difficult and inefficient. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0021] A tooling for welding silver contacts includes a feeding rack 4, a movable plate 9 that moves vertically relative to itself is provided below the feeding rack 4, and a guide cavity 5 is formed by the indentation of the top of the feeding rack 4 along its own length direction. Multiple positioning grooves 12 are sequentially opened inside the guide cavity 5 along its own length direction. A top plate 6 that moves vertically relative to itself is provided above the feeding rack 4. Multiple positioning heads 7 are sequentially fixedly connected to the bottom of the top plate 6 along its own length direction. The positioning heads 7 are matched with the guide cavity 5 one by one.

[0022] With the above technical solution, when personnel need to weld silver contacts, the metal plate for welding is placed under the moving plate 9. The moving plate 9 moves, causing the metal plate to move until it is close to the loading rack 4. Then, multiple silver contacts are placed in the guide cavity 5 in the loading rack 4. The silver contacts fall into the positioning groove 12 inside the guide cavity 5, thus positioning the silver contacts above the metal plate. The excess silver contacts in the guide cavity 5 are pushed and fall out of the guide cavity 5, thus completing the loading. The top plate 6 moves, which in turn moves the positioning head 7. The positioning head 7 is positioned by contacting the silver contacts, and the personnel can then weld the silver contacts.

[0023] In addition, in order to make the device more stable when it is working, the tooling also includes a support member. The support member is located below the movable plate 9, and a first electric push rod 10 is fixedly connected to the bottom of the support member. The telescopic end of the first electric push rod 10 is fixedly connected to the bottom of the movable plate 9.

[0024] In this embodiment, the first electric push rod 10 is supported by a support member. When a person needs to move the movable plate 9, the first electric push rod 10 works to move the movable plate 9, and the movable plate 9 moves the metal plate.

[0025] Furthermore, regarding how the feeding rack 4 is connected to the support component, such as... Figures 1-3 As shown, a bracket 3 is fixedly connected between the top of the support member and the feeding rack 4. Furthermore, regarding how the top plate 6 moves in this invention, as follows... Figures 1-3As shown, a second electric push rod 11 is fixedly connected to the top of the bracket 3, and the telescopic end of the second electric push rod 11 is fixedly connected to one side of the top plate 6.

[0026] In this embodiment, the support member supports the bracket 3, and the bracket 3 supports the feeding rack 4. When it is necessary to position the silver contact, the second electric push rod 11 works, thereby driving the top plate 6 to move. The top plate 6 drives the positioning head 7 to move, and the positioning head 7 abuts against the silver contact to fix it.

[0027] Specifically, in one embodiment, regarding the aforementioned support member, such as Figures 1-3 As shown, the support includes a base plate 1, a plurality of feet 2 are fixedly connected to the bottom of the base plate 1, and a first electric push rod 10 is fixedly connected to the bottom of the base plate 1.

[0028] In this embodiment, the base plate 1 and the first electric push rod 10 are supported by the base foot 2, thereby making the device more stable when it is working.

[0029] After the silver contact is placed in the feed chamber 5, in order to push down the excess silver contact, as follows: Figure 1 , Figure 2 and Figures 4-5 As shown, the material guide cavity 5 is provided with a push plate 8 that moves along its own length direction. The two sides of the feeding frame 4 are open to form side grooves 15, and the two sides of the feeding frame 4 are rotatably connected with screws 14. The screws 14 are located on one side of the side grooves 15, and the push plate 8 is sleeved between the two screws 14.

[0030] In this embodiment, after the personnel complete the feeding of silver contacts, the screw 14 is rotated, which causes the push plate 8 to move between the two side slots 15. The push plate 8 pushes the excess silver contacts in the guide cavity 5 to move, so that the excess silver contacts fall off the feeding rack 4.

[0031] Furthermore, regarding how the lead screw 14 rotates in this utility model, as follows: Figure 5 As shown, a motor 13 is fixedly connected to the outside of the feeding rack 4, and the output end of the motor 13 is connected to the lead screw 14.

[0032] In this embodiment, when it is necessary to drive the lead screw 14 to rotate, the motor 13 works to drive the lead screw 14 to rotate, and the lead screw 14 drives the push plate 8 to move.

[0033] 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.
