Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a welding machine clamping mechanism with a positioning structure. Background Art

[0002] A welding machine is a piece of equipment used to join metal or other materials. It typically includes a power source and a welding gun that joins metal parts together using an electric arc or other heating method. Welding machines can be used by welders in manufacturing, construction, auto repair, and other fields.

[0003] In the existing technology, when the welding machine is welding an object, the pressure it applies to the object may be too great, causing the object to shift. The shift will cause the position of the weld joint to deviate from the original design position, making the weld weak and reducing the strength and durability of the weld. This may cause the failure and damage of the welded structure, and if the weld needs to be repaired or re-welded after the welding shifts, it will increase additional labor hours and material costs. This will increase the time and cost of the welding process and may affect the progress of the entire manufacturing process. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 4As shown, the utility model provides a technical solution: a welding machine clamping mechanism with a positioning structure, comprising: a clamping mechanism 1, a buffer mechanism 2 is arranged on one side of the clamping mechanism 1, the clamping mechanism 1 comprises a workbench 11, a cross bar 12 is arranged on the top of the workbench 11, a lever 13 is arranged at the middle end of the cross bar 12, a connecting frame 14 is arranged at the bottom end of the lever 13, a clamping plate 15 is arranged at one end of the connecting frame 14, a locking ear 17 is arranged at one end of the clamping plate 15, a triangular plate 18 is arranged inside the locking ear 17, a spring piece 19 is arranged at the bottom end of the triangular plate 18, a workbench 11 is arranged at the bottom end of the spring piece 19, a hollow plate 110 is arranged on the top of the workbench 11, an extension plate 111 is arranged inside the hollow plate 110, a limiting rod 112 is arranged inside the extension plate 111, the top of the workbench 11 is fixedly connected to the bottom end of the cross bar 12, the cross bar 12 The middle end is movably connected to the middle end of the lever 13, one end of the lever 13 is movably connected to one side of the connecting frame 14, one end of the connecting frame 14 is fixedly connected to one side of the splint 15, one side of the splint 15 is fixedly connected to one end of the spring 16, the other end of the spring 16 is fixedly connected to one side of the inner wall of the workbench 11, one side of the splint 15 is fixedly connected to one end of the locking ear 17, the interior of the locking ear 17 is clamped with the outer side of the triangular plate 18, the bottom end of the triangular plate 18 is fixedly connected to the top end of the spring sheet 19, the bottom end of the spring sheet 19 is fixedly connected to the top side of the inner wall of the workbench 11, the top of the workbench 11 is fixedly connected to the bottom of the hollow plate 110, the interior of the hollow plate 110 is slidably connected to the outer side of the extension plate 111, the interior of the hollow plate 110 is connected through one end of the limiting rod 112, and the outer side of one end of the limiting rod 112 is clamped with the interior of the extension plate 111.

[0026] In this embodiment, when the staff is operating, in order to reduce the instability of the welding machine when welding the object, the object is placed between the clamping plate 15 and the extension plate 111, and then the lever 13 is manually operated to push the connecting frame 14 on the inner wall of the workbench 11 by using the lever principle. The connecting frame 14 and the clamping plate 15 are integrated and will naturally move. In this process, they will gradually approach the object until it is clamped and positioned. In the process of the movement of the clamping plate 15, the locking ear 17 has a certain slope. When the clamping plate 15 is close to the object, the locking ear 17 will exert pressure on the triangular plate 18, causing the spring piece 19 to retract. A clamping hole is designed in the locking ear 17. When the clamping hole is vertically aligned with the triangular plate 18, the triangular plate 18 will be clamped into the locking ear 17 by means of release, thereby limiting the clamping plate 15 so that the clamping force thereof is always consistent, thereby ensuring the stability and accurate position of the object during welding. In addition, the clamping and positioning device can make the operation more stable, reduce errors and repeated operations caused by unstable operation, and improve work efficiency.

[0027] Secondly, when facing a smaller object, due to the position limitation of the clamping plate 15, it is not possible to better contact the smaller object. Therefore, by moving the extension plate 111 outward in the hollow plate 110, the extension plate 111 is extended and contacts the smaller object, ensuring that the clamping plate 15 can position and clamp the object;

[0028] In addition, the spring 16 is designed to be at the rear side of the clamp 15, and when the clamp 15 is not subjected to external force, the spring 16 can use the retraction property to restore the clamp 15 to its initial position. This can ensure that the clamp 15 can automatically reset after use and be ready for the next use, thereby improving the continuity and efficiency of the operation without the need for additional operations.

[0029] Example 2

[0030] like Figure 1 - Figure 4 As shown, the buffer mechanism 2 includes a rubber pad 21 , one side of the rubber pad 21 contacts one side of the clamping plate 15 , the inside of the clamping plate 15 is threadedly connected to the outside of the screw 22 , and the outside of one end of the screw 22 is threadedly connected to the inside of the clamping plate 15 .

[0031] In this embodiment, by installing the rubber pad 21 on one side of the splint 15, the friction between the splint 15 and the object can be increased when the splint 15 contacts the object, thereby improving the clamping force. In this way, the object can be clamped more firmly to avoid movement or shaking during welding or processing. In addition, the rubber pad 21 can reduce the friction and scratches generated when the splint 15 contacts the object, thereby avoiding damage to the surface of the object. As time goes by and the frequency of use increases, the original rubber pad 21 may age, crack or harden. Therefore, the screws 22 inside the rubber pad 21 can be removed, and then the original rubber pad 21 can be replaced. This can be completed in a short time without large-scale disassembly or replacement of the entire splint 15. The normal use state of the splint 15 can be quickly restored, thereby improving operating efficiency.

[0032] Working principle:

[0033] like Figure 1 - Figure 4As shown, when the utility model is used, according to the needs of the user, the object is placed between the clamping plate 15 and the extension plate 111, and then the lever 13 is manually operated to move the clamping plate 15 by lever principle until it is clamped and positioned. In the process of the movement of the clamping plate 15, the locking ear 17 has a certain slope. When the clamping plate 15 is close to the object, the locking ear 17 will exert pressure on the triangular plate 18, so that the spring piece 19 retracts. A clamping hole is designed in the locking ear 17. When the position of the clamping hole is vertically matched with the triangular plate 18, the triangular plate 18 will be clamped into the locking ear 17 by release, so as to limit the clamping plate 15, so that the clamping force thereof is always consistent, thereby ensuring the stability and accurate position of the object during welding, and the clamping and positioning device can make the operation more stable.

[0034] By installing the rubber pad 21 on one side of the clamp 15, the friction between the clamp 15 and the object can be increased when the clamp 15 contacts the object, thereby improving the clamping force. This allows the object to be clamped more securely, avoiding movement or shaking during welding or processing. The rubber pad 21 can also reduce the friction and scratches generated when the clamp 15 contacts the object.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
