Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a novel grounding device for welding. Background Technology

[0002] Welding is a technique for permanently joining metals or other thermoplastic materials. Ground and welding clamp are the two output electrodes of an electric welding machine. During welding, the welding clamp, welding rod, workpiece and ground form a closed circuit, thereby realizing the welding operation.

[0003] Existing welding grounding devices mostly rely on clamps or magnetic adsorption to ensure stable contact with the workpiece. The application of clamps is limited by the shape of the workpiece, while magnetic adsorption offers wider applicability. However, regardless of whether it is clamps or magnetic adsorption, both methods use bolt or nut tightening technology when connecting to the grounding wire. Although this ensures a fixing effect, the connection process is cumbersome, requiring continuous turning of bolts or nuts, which slows down the connection speed and affects work efficiency and flexibility. Utility Model Content

[0004] In view of this, the present invention provides a novel grounding device for welding, which greatly improves the connection speed and convenience through the connection mechanism, realizes a quick and firm connection of the grounding wire, solves the problem of cumbersome connection process of traditional nut or bolt fastening method, and improves the efficiency and flexibility of welding operation.

[0005] To address the aforementioned technical problems, this utility model provides a novel grounding device for welding, comprising a mounting plate and a magnet disposed on the lower end face of the mounting plate. A threaded rod is provided at the center of the upper end face of the mounting plate, and a connecting plate is movably inserted into the outside of the threaded rod. A nut for locking the connecting plate is threaded onto the threaded rod. A grounding contact rod is provided at the end of the connecting plate, and a connecting mechanism for quickly connecting the grounding wire is rotatably connected to the upper end of the grounding contact rod. That is, the connection speed and convenience are greatly improved through the connecting mechanism, realizing a quick and secure connection of the grounding wire. This solves the problem of the cumbersome connection process of traditional nut or bolt fastening methods, and improves the efficiency and flexibility of welding operations.

[0006] The connecting mechanism includes a rotating cylinder rotatably connected to the upper end of the grounding contact rod. The lower end of the outer arc surface of the rotating cylinder has an opening. A pressing rod is slidably connected to the upper shaft of the rotating cylinder. A rectangular opening is provided on the surface of the pressing rod away from the opening. A ratchet plate is provided inside the rectangular opening. An assembly plate is provided on the top wall of the rotating cylinder near the ratchet plate. A pawl is rotatably connected inside the assembly plate. The pawl and the ratchet plate are configured to cooperate. A spring is provided at the bottom of the inner cavity of the assembly plate. The end of the spring is configured to cooperate with the end of the pawl. That is, when the pressing rod is operated, it moves downward. The ratchet plate inside the rectangular opening gradually pushes the pawl inside the assembly plate. The pawl jumps over the ratchet under the elastic action of the spring. Each jump achieves a first-level lock.

[0007] The connecting mechanism also includes a lever plate located at the upper end of the pawl. The upper ends of the mounting plate and the rotating cylinder are provided with through holes corresponding to the lever plate, which facilitates the release of the locking state between the ratchet plate and the pawl.

[0008] Both the lower end face of the pressing rod and the bottom wall of the rotating cylinder are provided with circular toothed plates. The two circular toothed plates are set together to firmly hold the ground wire and prevent the problem of disconnection.

[0009] It also includes a guide and limiting component, which is used to guide and limit the grounding wire. The guide and limiting component includes a guide plate set on the outer arc surface of the rotating cylinder near the lower end of the opening. The arc-shaped setting of the rear end of the guide plate makes it easy for the guide plate to fit with the grounding wire.

[0010] The guide limiting assembly also includes multiple elastic limiting plates respectively set on both sides of the upper surface of the guide plate. The upper end of the elastic limiting plate has an outward-flipping arc design, which allows the ground wire to enter the guide plate more smoothly when it contacts and slides.

[0011] It also includes a separation component, which is used to separate the magnet from the welded part. The separation component includes multiple L-shaped plates set on the lower end face of the mounting plate. The lower end of the magnet is provided with a clearance opening that corresponds to each L-shaped plate. That is, by inserting an external tool into the clearance opening, and then using the welded part as the point of action and the L-shaped plate as the fulcrum, the magnet and the welded part can be easily separated. Then, it can be repositioned to a new welding point, reducing preparation and repositioning time.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The relevant operator operates the pressing rod to move it downwards. The ratchet plate inside the rectangular opening gradually pushes the pawl inside the assembly plate. The pawl jumps over the ratchet under the elastic action of the spring plate. Each jump achieves a first-level lock until the two circular toothed plates tightly clamp the end of the ground wire. This greatly improves the connection speed and convenience, and achieves a quick and firm connection of the ground wire. It solves the problem of the cumbersome connection process of the traditional nut or bolt fastening method, and improves the efficiency and flexibility of welding operations.

[0014] 2. When it is necessary to remove the ground wire, simply move the lever. The lever will cause the pawl to overcome the spring force and lift up, thereby releasing the locking state between the ratchet plate and the pawl, making it easy for the relevant operators to remove the ground wire.

[0015] 3. After the ground wire is fixed, press the ground wire into the guide plate. During this process, the elastic limiting plate will be forced outward to avoid interference. After the ground wire enters the guide plate, the elastic limiting plate will reset to limit its position, ensuring that the ground wire is kept in the correct position and posture, and avoiding interference with the welding process.

[0016] 4. If it is necessary to change the welding position, the relevant operators can use an external tool inserted into the clearance opening, and then use the welded part as the point of action and the L-shaped plate as the fulcrum to easily separate the magnet from the welded part. Then, the magnet can be repositioned to the new welding point, reducing preparation and repositioning time. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1-4 As shown:

[0024] This embodiment provides a novel grounding device for welding, including a mounting plate 100 and a magnet 101 disposed on the lower end face of the mounting plate 100. The magnet 101 is ring-shaped, and the entire device can be fixed to the welding part by the attraction force of the magnet 101. A threaded rod 102 is provided at the center of the upper end face of the mounting plate 100. A connecting plate 103 is movably inserted into the outside of the threaded rod 102. A nut 104 for locking the connecting plate 103 is threadedly connected to the threaded rod 102. The connecting plate 103 is provided with a hole adapted to the threaded rod 102. The connecting plate 103 is inserted into the threaded rod 102 through the hole, and the connecting plate 103 is locked by tightening the nut 104. A grounding contact rod 105 is provided at the end of the connecting plate 103. The grounding contact rod 105 contacts the welding to realize the conduction of welding current. A connecting mechanism for quickly connecting the grounding wire is rotatably connected to the upper end of the grounding contact rod 105.

[0025] By inserting the connecting plate 103 onto the threaded rod 102 and locking the connecting plate 103 by tightening the nut 104, the relevant operator uses the magnet 101 to attract the mounting plate 100 and its auxiliary mechanism onto the welded part to ensure its stable positioning. At the same time, the grounding contact rod 105 accurately contacts the welding point of the welded part to realize current conduction, and then the grounding wire is quickly connected through the connecting mechanism.

[0026] like Figure 1-4 As shown, the connecting mechanism includes a rotating cylinder 200 rotatably connected to the upper end of the grounding contact rod 105. The lower end face of the rotating cylinder 200 has a rotating hole for providing rotational support. The lower end of the outer arc surface of the rotating cylinder 200 has an opening 201, which facilitates the insertion of the grounding wire into the rotating cylinder 200. A pressing rod 202 is slidably connected to the upper axis of the rotating cylinder 200. The pressing rod 202 consists of a rectangular plate in the middle and circular plates at both ends. A rectangular sliding opening for providing sliding support to the pressing rod 202 is provided at the upper axis of the rotating cylinder 200. A rectangular opening 203 is provided on the surface of the pressing rod 202 away from the opening 201. A ratchet plate 204 is provided inside the rectangular opening 203. The rectangular opening 203 is used for the ratchet plate 204... The rotating cylinder 200 has an assembly plate 205 located on its top wall near the ratchet plate 204. A pawl 206 is rotatably connected inside the assembly plate 205. The inner wall of the assembly plate 205 has a rotating hole for providing rotational support for the pawl 206. The pawl 206 and the ratchet plate 204 are configured to cooperate and lock the pressing rod 202. A spring piece 207 is located at the bottom of the inner cavity of the assembly plate 205. The end of the spring piece 207 cooperates with the end of the pawl 206 to operate the pressing rod 202, causing it to move downward. The ratchet plate 204 inside the rectangular opening 203 gradually pushes the pawl 206 inside the assembly plate 205. Under the elastic action of the spring piece 207, the pawl jumps over the ratchet, and each jump achieves a first-level lock.

[0027] By passing the end of the grounding wire through the opening 201 and inserting it between the two circular toothed plates 300 inside the rotating cylinder 200, the operator then operates the pressing rod 202 to move it downwards. The ratchet plate 204 inside the rectangular opening 203 gradually pushes the pawl 206 inside the assembly plate 205. Under the elastic action of the spring piece 207, the pawl jumps over the ratchet, achieving a first-level lock with each jump, until the two circular toothed plates 300 tightly clamp the end of the grounding wire. This greatly improves the connection speed and convenience, achieving a quick and secure connection of the grounding wire. It solves the problem of cumbersome connection process in traditional nut or bolt fastening methods, and improves the efficiency and flexibility of welding operations.

[0028] like Figure 1-3 As shown, the connecting mechanism also includes a lever 208 disposed on the upper end of the pawl 206. The lever 208 is composed of a lower plate and an upper cylinder. The upper ends of the assembly plate 205 and the rotating cylinder 200 are provided with through holes 209 corresponding to the lever 208, which are used to provide a moving place for the lever 208.

[0029] When it is necessary to remove the ground wire, simply move the lever 208. The lever 208 causes the pawl 206 to overcome the spring force of the spring piece 207 and lift up, thereby releasing the locked state of the ratchet plate 204 and the pawl 206, making it easy for relevant operators to remove the ground wire.

[0030] like Figure 2-4 As shown, both the lower end face of the pressing rod 202 and the bottom wall of the rotating cylinder 200 are provided with circular toothed plates 300. The circular toothed plates 300 are circular plates with evenly distributed ratchet teeth on their end faces. The two circular toothed plates 300 are set together to firmly hold the grounding wire and prevent the problem of disconnection.

[0031] like Figure 1-4 As shown, it also includes a guide and limiting component, which is used to guide and limit the ground wire. The guide and limiting component includes a guide plate 400 disposed on the outer arc surface of the rotating cylinder 200 near the lower end of the opening 201. The rear end of the guide plate 400 is arc-shaped, which makes it easy to fit the ground wire.

[0032] like Figure 1-4 As shown, the guide limiting assembly also includes multiple elastic limiting plates 401 respectively disposed on both sides of the upper surface of the guide plate 400. The upper end of the elastic limiting plate 401 has an outwardly flipped arc design, which allows it to enter the guide plate 400 more smoothly when the ground wire contacts and slides with it.

[0033] like Figure 1-2As shown, it also includes a separation component, which is used to separate the magnet 101 from the welded part. The separation component includes a plurality of L-shaped plates 500 disposed on the lower end face of the mounting plate 100. The L-shaped plates 500 are located inside the magnet 101 and are evenly distributed in a ring. The lower end of the magnet 101 is provided with a clearance opening 501 corresponding to the L-shaped plates 500 to facilitate tool insertion.

[0034] The relevant operators can use external tools to insert into the clearance opening 501, and then use the welded part as the point of action and the L-shaped plate 500 as the fulcrum to easily separate the magnet 101 from the welded part. Then, they can reposition it to a new welding point, reducing preparation and relocation time.

[0035] The working principle of the novel grounding device for welding provided by this utility model is as follows: First, the operator inserts the connecting plate 103 onto the threaded rod 102 and locks the connecting plate 103 by tightening the nut 104. Then, the operator uses the magnet 101 to attract the mounting plate 100 and its auxiliary mechanisms onto the welding part to ensure its stable positioning. At the same time, the grounding contact rod 105 accurately contacts the welding point of the welding part to realize current conduction. Afterwards, the end of the grounding wire is passed through the opening 201 and inserted into the rotating cylinder 200. Between the two circular toothed plates 300 inside, the operator operates the pressing rod 202 to move it downwards. The ratchet plate 204 inside the rectangular opening 203 gradually pushes the pawl 206 inside the assembly plate 205. The pawl 206 jumps over the ratchet under the elastic action of the spring piece 207, achieving a first-level lock with each jump, until the two circular toothed plates 300 tightly clamp the end of the ground wire. This greatly improves the connection speed and convenience, achieving a quick and secure connection of the ground wire, and solving the problem of the cumbersome connection process of traditional nut or bolt fastening methods. To improve the efficiency and flexibility of welding operations, when it is necessary to remove the ground wire, simply move the lever 208. The lever 208 causes the pawl 206 to overcome the spring force of the spring piece 207, thereby releasing the locking state of the ratchet plate 204 and the pawl 206, making it easy for the relevant operators to remove the ground wire. After the ground wire is fixed, press the ground wire body into the guide plate 400. During this process, the elastic limiting plate 401 is forced outward to avoid it. After the ground wire body enters the guide plate 400, the elastic limiting plate 401 resets and continues to move. The limit switch ensures that the ground wire is kept in the correct position and posture to avoid interfering with the welding process. When the welding operation begins, the current is effectively transmitted through the ground wire, the circular toothed plate 300, the rotating cylinder 200 and the ground contact rod 105 to complete the welding task. If it is necessary to change the welding position, the relevant operators can use an external tool inserted into the clearance opening 501, and then use the welded part as the point of action and the L-shaped plate 500 as the fulcrum to easily separate the magnet 101 from the welded part. Then, the position can be repositioned to the new welding point, reducing preparation and repositioning time.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] 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 should also be considered within the protection scope of this utility model.
