Description

Technical Field

[0001] This utility model belongs to the field of grounding clamp technology, specifically relating to a new type of welding machine grounding clamp. Background Technology

[0002] Grounding clamps are special clamps used in electric welding operations to connect the grounding wire of the welding machine to the workpiece. Their main function is to establish a stable current circuit and ensure welding quality.

[0003] While existing spring grounding clamps are convenient to operate and can accommodate workpieces of varying thicknesses, their clamping force is limited. As the springs tire, their elasticity decreases, potentially affecting connection strength. Operators must check the clamping force of the spring grounding clamp before use to avoid safety hazards and ensure proper use. Therefore, designing a new type of welding machine grounding clamp is a problem we need to solve. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a new type of welding machine grounding clamp.

[0005] To achieve the above objectives, this utility model provides a novel welding machine grounding clamp, comprising two rebar clamps, with a first connector and a second connector respectively fixedly connected to the outer walls of the two rebar clamps, the first connector being inserted into the interior of the second connector, and a connecting bolt being threaded into the interior of one of the rebar clamps; and a locking assembly for assisting in locking the grounding clamp, the locking assembly being connected to the rebar clamp, the first connector, and the second connector.

[0006] In the above technical solution, the locking assembly further includes a gripping sleeve fixedly connected to the outer wall of the rebar clamp, the number of gripping sleeves corresponding to the number of rebar clamps, a rotating sleeve rotatably connected to the outer wall of the gripping sleeve, and an arc-shaped groove opened on the outer wall of the gripping sleeve, the rotating sleeve being slidably connected inside the arc-shaped groove.

[0007] In the above technical solution, a first clamping plate is inserted into the inside of the rotating sleeve, a first torsion spring is fixedly connected to the outer wall of the first clamping plate, and a connecting block is fixedly connected to the end of the first torsion spring away from the first clamping plate.

[0008] In the above technical solution, the connecting block is further inserted into the inside of the first torsion spring, and a threaded rod is fixedly connected to one end of the connecting block. The first clamping plate is threadedly connected to the outer wall of the threaded rod.

[0009] In the above technical solution, further, a stepped rod is fixedly connected to the end of the threaded rod away from the connecting block, the stepped rod is inserted into the inside of the first connecting member and the second connecting member, and a second clamping plate is fixedly connected to the end of the stepped rod away from the threaded rod, the second clamping plate is inserted into the inside of the rotating sleeve.

[0010] In the above technical solution, a second torsion spring is further sleeved on the outer wall of the stepped rod, and the two ends of the second torsion spring are respectively fixedly connected to the inside of the first connector and the second connector.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting a locking component, the grounding clamp can improve the connection strength of the grounding clamp while ensuring the advantages of the spring grounding clamp, preventing the grounding clamp from falling off the workpiece, avoiding problems such as falling off due to insufficient clamping force and unstable electric arc, and avoiding quality defects in the weld, or even electric shock accidents to workers.

[0013] By setting up steel bar clamps, the steel bar clamps can be made stable during long-term, high-intensity electric welding operations. This reduces the risk of the grounding clamps falling off due to material fatigue or wear, and can also significantly improve the overall durability of the grounding clamps. It avoids problems such as the grounding clamps falling off due to material fatigue or wear, and unstable electric arc, thus ensuring the stability of the welding arc and the safety of the welding operation.

[0019] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 The novel welding machine grounding clamp shown includes two rebar clamps 1. The rebar clamps 1, being made of rebar material, ensure stability during prolonged, high-intensity welding operations and significantly improve the overall durability of the grounding clamp. This prevents problems such as clamp detachment due to material fatigue or wear, and arc instability, ensuring the stability of the welding arc and the safety of the welding operation. The outer walls of the two rebar clamps 1 are respectively fixedly connected to a first connector 2 and a second connector 3. The first connector 2 is inserted into the interior of the second connector 3. Anti-slip features on the contact surfaces of the first and second connectors 3 further increase the rotational resistance after clamping and fixing, thus increasing the clamping force of the grounding clamp. One of the rebar clamps 1 has a threaded connection to a connecting bolt 4, which is a component used in existing welding machine wiring and will not be described in detail. A locking assembly is used to assist in locking the grounding clamp and is connected to the rebar clamp 1, the first connector 2, and the second connector 3.

[0021] like Figures 1 to 4As shown, the locking assembly includes a gripping sleeve 5 fixedly connected to the outer wall of the rebar clamp 1. The number of gripping sleeves 5 corresponds to the number of rebar clamps 1. A rotating sleeve 6 is rotatably connected to the outer wall of the gripping sleeve 5. The rotating sleeve 6 has a displacement allowance inside. The first clamping plate 8 and the second clamping plate 13 remain inside the rotating sleeve 6 after the distance between them is changed. An arc-shaped groove 7 is provided on the outer wall of the gripping sleeve 5. The rotating sleeve 6 is slidably connected inside the arc-shaped groove 7. The rotation angle of the rotating sleeve 6 is limited by the arc-shaped groove 7. The first clamping plate 8 is inserted into the inside of the rotating sleeve 6. A first torsion spring 9 is fixedly connected to the outer wall of the first clamping plate 8. A connecting block 10 is fixedly connected to the end of the first torsion spring 9 away from the first clamping plate 8. The connecting block 10 is inserted into the inside of the first torsion spring 9. A threaded rod 11 is fixedly connected to one end of the connecting block 10. The first clamping plate 8 is threadedly connected to the threaded rod. On the outer wall of the threaded rod 11, a stepped rod 12 is fixedly connected to the end of the threaded rod 11 away from the connecting block 10. The stepped rod 12 is inserted into the interior of the first connecting member 2 and the second connecting member 3. By setting the stepped rod 12, the first connecting member 2 and the second connecting member 3 will press against the stepped surface of the stepped rod 12 when they are clamped and fixed, preventing the first connecting member 2 and the second connecting member 3 from sliding along the outer wall of the stepped rod 12 after being clamped and fixed, thus affecting the clamping effect. A second clamping plate 13 is fixedly connected to the end of the stepped rod 12 away from the threaded rod 11. The second clamping plate 13 is inserted into the interior of the rotating sleeve 6. It should be noted that the first clamping plate 8 and the second clamping plate 13 are respectively inserted into two different rotating sleeves 6. A second torsion spring 14 is sleeved on the outer wall of the stepped rod 12. The two ends of the second torsion spring 14 are fixedly connected to the interior of the first connecting member 2 and the second connecting member 3, respectively.

[0022] Working principle: When the operator uses the grounding clamp, they first hold the grip sleeve 5 and the rotating sleeve 6. During this process, the rotating sleeve 6 is first squeezed by the palm, causing it to rotate and slide along the inside of the arc-shaped groove 7 until it overlaps with the grip sleeve 5. The overlap of the rotating sleeve 6 and the grip sleeve 5 will push the corresponding first clamping plate 8 and second clamping plate 13 to rotate. The first clamping plate 8 rotates along the outer wall of the threaded rod 11, and the second clamping plate 13 drives the threaded rod 11 to rotate relative to the first clamping plate 8 through the stepped rod 12. This allows the first clamping plate 8 and the threaded rod 11 to rotate relative to each other, and the second clamping plate 13 and the first clamping plate 8 to rotate relative to each other. As the spacing increases, the clamping and fixing of the first connector 2 and the second connector 3 ceases. As the grip continues, the gripping sleeve 5 and the rotating sleeve 6 will cause the two steel bar clamps 1 to open. The two steel bar clamps 1 will then rotate and open around the threaded rod 11 via the first connector 2 and the second connector 3. At this point, the grounding clamp can be clamped onto the desired workpiece. It should be noted that when the first clamping plate 8 and the threaded rod 11 rotate relative to each other, the first clamping plate 8 will drive the first torsion spring 9 to rotate, and the threaded rod 11 will drive the first torsion spring 9 to rotate via the connecting block 10. The two rotations are in opposite directions, causing the first torsion spring 9 to twist and store force.

[0023] Furthermore, when the worker clamps the grounding clamp onto the workpiece and stops holding the clamp, the first torsion spring 9 loses pressure and begins to release the stored torsional force, causing the first clamping plate 8 to rotate in the opposite direction to reset. This, in turn, drives the second clamping plate 13 to rotate in the opposite direction to reset via the connecting block 10, threaded rod 11, and stepped rod 12, until the first clamping plate 8 and the second clamping plate 13 are rotated to their initial states and then stop. During this process, the relative positions of the first clamping plate 8 and the threaded rod 11 also reset, allowing the first clamping plate 8 and the second clamping plate 13 to reposition themselves. The reduced spacing of 13 allows for the re-clamping and fixing of the first connector 2 and the second connector 3, preventing them from rotating. This ensures the clamping force and stability of the grounding clamp on the workpiece, enhancing its connection strength while maintaining the advantages of spring grounding clamps. This prevents the grounding clamp from detaching from the workpiece, avoiding problems such as detachment due to insufficient clamping force, unstable electric arc, and weld quality defects. It also prevents accidents such as electric shock to workers.
