Description

Technical Field

[0001] This utility model relates to the field of anchoring nut technology, and more specifically, to a device for anchoring nuts. Background Technology

[0002] In the spot welding anchoring operation of nuts, the sheet metal parts and the nut parts need to be precisely positioned before welding. In traditional devices, when the sheet metal parts and the nut parts are placed on the welding rod, there is a lack of a stable clamping structure. They are prone to displacement due to vibration or external force during the welding process, resulting in poor adhesion between the two welding surfaces and affecting the welding quality. At the same time, due to the high temperature after welding, the sheet metal parts and the welding rod often stick together locally. At this time, there is a lack of an effective separation structure, making it difficult for operators to remove the sheet metal parts. This not only affects the work efficiency, but may also cause damage to the sheet metal parts or the welding rod due to forced disassembly. Therefore, in order to solve the above problems, a device for anchoring nuts is proposed. Utility Model Content

[0003] To overcome the above-mentioned defects of the prior art, the present invention provides a device for anchoring nuts. The device uses a moving groove, a moving rod, a spring, a clamping plate and a stabilizing pad in a placement platform. The elasticity of the spring drives the moving rod to move the clamping plate to form a stable clamp on the sheet metal part, so that the sheet metal part and the nut part remain relatively fixed during the welding process, avoiding the instability of the welding surface due to displacement, and ensuring the stability of the anchoring welding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for anchoring nuts, comprising a nut spot welding machine, one end of which is fixedly connected to a welding rod, the upper end of which is provided with a spot welding arm, the spot welding arm being electrically connected to the nut spot welding machine; a placement column is fixedly connected to the top end of the welding rod, a placement platform is sleeved on the placement column, the bottom surface of the placement column is welded and fixedly connected to the surface of the welding rod, a sheet metal part is placed on the upper end of the placement column, a nut is placed on the surface of the sheet metal part, and both the sheet metal part and the nut are sleeved on the placement column; a movable groove is provided inside the placement platform, a movable rod is movably arranged inside the movable groove, a clamping plate is fixedly connected to the outside of the movable rod, and a spring is wound around the outer wall of the movable rod.

[0005] In a preferred embodiment, a stabilizing pad is attached to the inner wall surface of the clamping plate, the stabilizing pad is in contact with one side of the nut, and the stabilizing pad is made of rubber.

[0006] In a preferred embodiment, the moving slots are arranged symmetrically on the placement platform, and a stabilizing slot is provided in the middle of the two sets of moving slots. A stabilizing plate is slidably attached to the inside of the stabilizing slot, and the stabilizing plate is fixedly connected to the clamping plate.

[0007] In a preferred embodiment, a pull handle is attached and fixedly connected to the outer wall of the clamping plate. The pull handle is arc-shaped and made of rubber and plastic.

[0008] In a preferred embodiment, a support column is fixedly connected to the side of the placement platform, and a pry bar is rotatably connected inside the support column. The pry bar is located in the middle part of the support column. A hinge block is provided at one end of the pry bar, and a pressing pad is fixedly connected to the other end of the pry bar. The hinge block is fixedly connected to the pry bar at one end of its hinge joint, and a pry block is fixedly connected to the other end of the hinge block. Each set of pry blocks is in contact with the bottom surface of the sheet metal part.

[0009] In a preferred embodiment, the support, pry bar, hinge block, pry bar and pressing pad are arranged symmetrically on the placement platform.

[0010] The technical effects and advantages of this utility model are as follows: This device sets up a moving groove, a moving rod, a spring, a clamping plate and a stabilizing pad in the placement platform. The elasticity of the spring drives the moving rod to move the clamping plate to form a stable clamping on the sheet metal part, so that the sheet metal part and the nut part remain relatively fixed during the welding process, avoiding the instability of the welding surface due to displacement, and ensuring the stability of the anchor welding.

[0011] In addition, the support pillars, pry bars, hinge blocks, pry blocks, and pressing pads on the side of the platform work together. When the sheet metal parts stick to the welding rod at high temperatures, the operator presses the pressing pads and uses the leverage of the pry bars to drive the pry blocks upward through the hinge blocks. This effectively separates the stuck parts, allowing the sheet metal parts to detach smoothly from the welding rod. This solves the problem of difficult removal of parts after welding and improves the overall smoothness of the operation. Attached Figure Description

[0017] 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.

[0018] Refer to the instruction manual appendix Figure 1-4 An anchoring nut device includes a nut spot welding machine 1, with a welding rod 2 fixedly connected to one end of the welding machine 1. A spot welding arm 3 is provided at the upper end of the welding rod 2, and the spot welding arm 3 is electrically connected to the nut spot welding machine 1. A placement column 6 is fixedly connected to the top end of the welding rod 2, and a placement platform 7 is fixedly fitted onto the outside of the placement column 6. The bottom surface of the placement column 6 is welded and fixedly connected to the surface of the welding rod 2. A sheet metal part 4 is placed on the upper end of the placement column 6, and a nut part 5 is placed on the surface of the sheet metal part 4. Both the sheet metal part 4 and the nut part 5 are fitted onto the placement column 6. The placement platform 7 is internally... A movable groove 8 is provided, and a movable rod 9 is movable inside the movable groove 8. A clamping plate 10 is fixedly connected to the outside of the movable rod 9, and a spring 12 is wound around the outer wall of the movable rod 9. The elasticity of the spring 12 can drive the movable rod 9 to move inward and drive the clamping plate 10 and the stabilizing pad 11 to clamp and fix the sheet metal part 4. This ensures that the sheet metal part 4 is more stable on the welding rod 2 when the nut part 5 and the sheet metal part 4 are anchored and welded to the spot welding arm 3, and avoids problems in the anchoring nut operation due to unstable welding surfaces between the nut part 5 and the sheet metal part 4.

[0019] Then, a stabilizing pad 11 is attached to the inner wall surface of the clamping plate 10. The stabilizing pad 11 is attached to one side of the nut 5. The stabilizing pad 11 is made of rubber. When the stabilizing pad 11 contacts the sheet metal part 4, the elasticity of the rubber material itself increases the contact area between the two. At the same time, the high coefficient of friction of the rubber causes the stabilizing pad 11 and the sheet metal part 4 to generate a large frictional force, which further restricts the relative movement of the sheet metal part 4 and the nut 5 during the welding process and improves its stability on the welding rod 2.

[0020] Subsequently, the moving slots 8 are symmetrically arranged on the placement platform 7. A stabilizing slot 13 is provided in the middle of the two sets of moving slots 8. A stabilizing plate 14 is slidably attached inside the stabilizing slot 13. The stabilizing plate 14 is fixedly connected to the clamping plate 10. When the moving rod 9 moves inside the moving slot 8, the stabilizing plate 14 will slide synchronously inside the stabilizing slot 13 along with the clamping plate 10. The slot wall of the stabilizing slot 13 constrains the stabilizing plate 14, preventing the moving rod 9 from shifting laterally or rotating during the movement. This ensures that the moving rod 9 always moves along the axial direction of the moving slot 8, thereby ensuring that the clamping force of the clamping plate 10 on the sheet metal part 4 is stable and that the operation of each component of the equipment is coordinated.

[0021] Next, a pull handle 15 is attached and fixed to the outer wall of the clamping plate 10. The pull handle 15 is arc-shaped and made of rubber and plastic. When the operator pulls the pull handle 15, the arc-shaped structure can naturally fit the palm. The softness of the rubber and plastic material can reduce the pressure on the hand. At the same time, the friction of its surface can prevent the hand from slipping during the pulling process, making it easy for the operator to apply pulling force. The pull handle 15 drives the clamping plate 10 and the moving rod 9 to move outward together, so that the spring 12 is stretched. At this time, the clamping plate 10 separates from the sheet metal part 4, and the sheet metal part 4 is released from the fixing effect with the welding rod 2, ensuring that the operator can smoothly remove the sheet metal part 4 from the welding rod 2.

[0022] At this time, a support column 16 is fixedly connected to the side of the placement platform 7. A pry bar 17 is rotatably connected inside the support column 16. The pry bar 17 is located in the middle part of the support column 16. A hinge block 18 is provided at one end of the pry bar 17, and a pressing pad 20 is fixedly connected to the other end of the pry bar 17. One end of the hinge block 18 is fixedly connected to the pry bar 17 at the hinge joint, and a pry block 19 is fixedly connected to the other end of the hinge block 18. Each set of pry blocks 19 is in contact with the bottom surface of the sheet metal part 4; when the nut part 5 is in contact with the sheet metal part 4... After the metal part 4 is anchored and welded, if the high temperature during the welding process causes the sheet metal part 4 to partially stick to the welding rod 2, the operator should press down on the pressing pad 20. The pry bar 17 will rotate around the support column 16 as the fulcrum, and its other end will drive the pry block 19 to lift upward through the hinge block 18. The pry block 19 will contact the bottom surface of the sheet metal part 4 and apply an upward pushing force to separate the sticky parts, so that the sheet metal part 4 can be freed from the restraint of the welding rod 2, thus avoiding the situation where the sheet metal part 4 cannot be removed due to sticking.

[0023] It should be noted that the support column 16, pry bar 17, hinge block 18, pry bar 19, and pressing pad 20 are arranged symmetrically on the placement platform 7. The two sets of symmetrical structures allow the two pry bars 19 to act on both sides of the bottom of the sheet metal part 4 respectively. When the pushing force is applied, the force on both sides of the sheet metal part 4 is equal in magnitude and symmetrical in direction, which avoids the sheet metal part 4 from tilting or deforming due to uneven force. At the same time, the simultaneous application of force on both sides can disperse the force, reduce the stress intensity of individual parts, and improve the efficiency and success rate of the sheet metal part 4 detaching from the welding rod 2.

[0024] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
