Description

Technical Field

[0001] This utility model relates to a weaving device, and more particularly to a tungsten electrode clamping fixture. Background Technology

[0002] In the development of welding technology, tungsten electrodes, as a commonly used electrode material, are widely used in welding processes such as tungsten inert gas welding (TIG welding). In TIG welding, the tungsten electrode transfers current to the workpiece, which is fundamental to the generation of the welding arc. The existing tungsten electrode specifications are φ3.2×150mm. When using tungsten electrodes, operators typically divide a single electrode into five equal segments (30mm / segment), then grind the tips for arc initiation. After the tips blacken or melt, they are ground again, and this process is repeated until the electrode can no longer be ground. To ensure welding quality and stability, tungsten electrode clamping fixtures are used to hold the electrode, maintaining its correct position and orientation during welding, and allowing for easy electrode replacement.

[0003] Currently available tungsten electrode clamping fixtures use excessively large elastic chucks and internally taper nuts, making it impossible to effectively grind tungsten electrodes shorter than 22mm. This results in 110mm of unusable tungsten electrode length per electrode, leading to significant waste, poor practicality, and high operating costs. Therefore, it is necessary to design a compact, low-energy-consumption, and highly practical tungsten electrode clamping fixture. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a tungsten electrode clamping fixture, which achieves the purpose of having a small size, low energy consumption and high practicality.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A tungsten electrode clamping fixture includes a hand handle, a tapered nut, and a flexible chuck. The hand handle has a nut seat that is threadedly connected to the tapered nut, and the flexible chuck is located inside the hand handle and the tapered nut. The flexible chuck includes a through-connected flexible clamping part and an auxiliary clamping part. The periphery of the flexible clamping part has multiple movable openings, and the lower ends of the movable openings extend toward the auxiliary clamping part. The nut seat has a limiting opening that mates with the auxiliary clamping part for saving and stabilizing the tungsten electrode.

[0007] Preferably, the upper opening of the elastic clamping part is smaller than the inner diameter of the auxiliary clamping part, the auxiliary clamping part is in communication with the hand handle, and the length of the auxiliary clamping part is smaller than the length of the hand handle.

[0008] Preferably, the lower outer side of the elastic clamping part is provided with an embedding groove, and an elastic ring is sleeved in the embedding groove. The elastic ring is made of elastic material.

[0009] Preferably, a first protective ring is fixed to the inner side of the elastic clamping part, and a second protective ring is fixed to the inner side of the auxiliary clamping part for the protection of the tungsten electrode.

[0010] Preferably, the outer side of the conical nut is provided with several rough strips, and the inner side of the conical nut is provided with a frosted layer for stable positioning of the elastic clamp.

[0011] Preferably, the inner side of the tapered nut has a threaded groove, and the outer side of the nut seat has a thread that mates with the threaded groove. The tapered nut is located outside the nut seat.

[0012] Preferably, a locking washer is fitted between the hand handle and the nut seat, the inner side of the locking washer has a snap-fit ​​groove that fits with the hand handle and the nut seat, and one side of the locking washer has an opening.

[0013] Compared with existing technologies, the tungsten electrode clamping fixture provided by this utility model has the advantages of small size, low energy consumption, high practicality, and low processing cost. Specifically, by dividing the elastic chuck into an elastic clamping part and an auxiliary clamping part, the elastic clamping part can be confined in a small volume between the nut seat and the conical nut, while the auxiliary clamping part can penetrate the nut seat and be stably mounted on the hand handle. This allows the clamping fixture to clamp shorter tungsten electrodes, reducing tungsten electrode waste, improving practicality, and lowering processing costs.

[0014] Furthermore, the use of a locking washer between the tapered nut and the nut seat increases the connection strength between the tapered nut and the nut seat; the outer elastic ring of the elastic collet facilitates the clamping of the auxiliary elastic clamping part with the tungsten electrode, and the elastic fit of the first and second protective rings with the tungsten electrode facilitates the clamping of shorter tungsten electrodes, increases the clamping stability between the elastic collet and the tungsten electrode, and prevents the tungsten electrode from slipping and breaking, which is very beneficial to the use of the tungsten electrode.

[0015] It should be understood that the general descriptions and details herein are exemplary and illustrative only and are not intended to limit this disclosure.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] As attached Figure 1 To be continued Figure 6As shown, the tungsten electrode clamping fixture provided in this embodiment of the present invention currently includes three parts: a hand lever 1, a conical nut 2, and an elastic chuck 3. The hand lever 1 is provided with a nut seat 13 threadedly connected to the conical nut 2. When using the clamping fixture, the tungsten electrode is first clamped using the elastic chuck 3, and then both ends of the tungsten electrode are passed through the conical nut 2 and the nut seat 13 respectively. By tightening the conical nut 2 onto the nut seat 13, the elastic chuck 3 is positioned between the hand lever 1 and the conical nut 2, and is located inside both structures. Holding the hand lever 1 allows for grinding of the tungsten electrode exposed by the conical nut 2. To save on tungsten electrode waste, the elastic chuck 3 can be designed as a through-connected elastic clamping part 4 and an auxiliary clamping part 5. The elastic clamping part 4... Multiple movable openings 6 are provided around the elastic chuck 3. The upper end of the movable opening 6 extends to the edge of the elastic clamping part 4, and the lower end of the movable opening 6 can continue to extend towards the auxiliary clamping part 5, so that multiple clamping plates are provided around the elastic chuck 3 for clamping the tungsten electrode. When the tungsten electrode passes through the elastic chuck 3, the auxiliary clamping part 5 can clamp the tungsten electrode for a longer length, so that the tungsten electrode can be ground for a shorter length, reducing the waste of the tungsten electrode. Finally, a limiting opening 14 that can be used with the auxiliary clamping part 5 is provided on the nut seat 13. When the elastic chuck 3 is connected to the hand handle 1, the auxiliary clamping part 5 can pass through the limiting opening 14 and the nut seat 13 and be inserted into the hand handle 1, increasing the connection between the elastic chuck 3 and the hand handle 1, facilitating the saving of tungsten electrode and stable clamping.

[0027] It is worth noting that, for example Figure 3 As shown, in some embodiments, the elastic chuck 3 can be made entirely of elastic metal material, and the upper opening size of the elastic clamping part 4 is smaller than the inner diameter of the auxiliary clamping part 5, so that the elastic clamping part 4 is mainly the clamping end of the tungsten electrode, and the auxiliary clamping part 5 is mainly the storage end of the tungsten electrode. The elastic chuck can hold 14mm tungsten electrodes, and each tungsten electrode segment can be saved, so the workpiece can be clamped with a saving of 40mm for each tungsten electrode. When the tungsten electrode and the elastic chuck 3 are installed, the auxiliary clamping part 5 is connected to the hand handle 1. The setting that the length of the auxiliary clamping part 5 is less than the length of the hand handle 1 makes it convenient to store the tungsten electrode and the elastic chuck 3 in the hand handle 1, sealing the tungsten electrode, which is very beneficial for the stable storage of the tungsten electrode and ensures the safe use of the tungsten electrode.

[0028] To ensure the stability of the elastic chuck 3 in holding the tungsten electrode, such as Figure 4 As shown, in some embodiments, an embedding groove 7 can be opened on the lower outer side of the elastic clamping part 4, and an elastic ring 8 can be fitted in the embedding groove 7. The elastic ring 8 is made of an elastic material, such as elastic plastic, rubber, silicone, etc. When the tungsten electrode is inserted into the elastic clamping part 4, the elastic ring 8 can assist the elastic clamping part in clamping the tungsten electrode, increasing the connection between the tungsten electrode and the elastic chuck 3, and providing favorable conditions for short-length tungsten electrode grinding.

[0029] Secondly, such as Figure 5 As shown, in some embodiments, a first protective ring 9 may be fixed to the inner side of the elastic clamping part 4, and a second protective ring 10 may be fixed to the inner side of the auxiliary clamping part 5. The first protective ring 9 may use a wave-shaped structure to provide greater protection for the tungsten electrode. Furthermore, both the first protective ring 9 and the second protective ring 10 may be made of materials such as rubber or elastic plastic. By utilizing the characteristics of the first protective ring 9 and the second protective ring 10 and their materials, the tungsten electrode is elastically protected, preventing breakage and providing better clamping.

[0030] To facilitate the connection between the tapered nut 2 and the handle 1, such as Figure 6 As shown, in some embodiments, several rough strips 11 can be provided on the outside of the tapered nut 2, and a frosted layer 12 can be provided on the inside of the tapered nut 2. When the tapered nut 2 is connected to the hand handle 1, the thread provided on the inside of the tapered nut 2 can be used to engage with the thread provided on the outside of the nut seat 13, so that the tapered seat is installed on the outside of the nut seat 13. At the same time, the frosted layer 12 can be located on the upper circumference of the nut seat 13, and the nut seat 13 can be tightly fitted with the frosted layer 12, so that the elastic chuck 3 is stably limited on the hand handle 1 and the tapered nut 2, increasing the clamping firmness of the clamping fixture on the tungsten electrode, and providing favorable conditions for the short-specification grinding of the tungsten electrode.

[0031] Furthermore, to increase the stability of the connection between the tapered nut 2 and the handle 1, in some embodiments, such as... Figure 2 As shown, a locking washer 15 can be fitted between the handle 1 and the nut seat 13. The inner side of the locking washer 15 has a snap-fit ​​groove 16 that can fit with the handle 1 and the nut seat 13, so that the locking washer 15 can be stably locked on the handle 1. Then, an opening can be provided on one side of the locking washer 15. The locking washer 15 can be used to lock the conical nut 2 more firmly and prevent the conical nut 2 from loosening with the nut seat 13.

[0032] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
