Description

Technical Field

[0001] This utility model relates to the field of hot riveting welding equipment, specifically a pulse servo hot riveting welding equipment. Background Technology

[0002] Hot riveting welding is a type of electric welding, mainly suitable for joining workpieces made of different materials. One workpiece has a rivet, which is inserted into the hole of another workpiece. Then, the rivet melts and deforms through the welding joint to form a rivet head, locking the two workpieces together. This process is fast and economical, and has the advantage of not requiring the consumption of rivets or screws.

[0003] According to the patent document CN221494750U, a movable temperature control device for hot riveting welding is disclosed. It includes a hot riveting welding mechanism and a movable temperature control mechanism. The movable temperature control mechanism is fixedly connected to the front of the hot riveting welding mechanism and includes a transmission box. A motor is fixedly connected to the bottom left side of the inner cavity of the transmission box. A gear one is fixedly connected to the output end of the motor. A gear two is movably connected to the back of the inner cavity of the transmission box via a rotating shaft. The left side of gear two meshes with gear one. This technical solution changes the traditional limitation of not being able to move to each welding point. The use of an L-shaped plate allows the temperature controller to move left and right, enabling precise temperature control at different hot riveting welding positions without affecting the quality of the welding. However, while this solution achieves precise temperature control, it cannot quickly cool the workpiece after hot riveting welding, which is inconvenient in use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pulse servo hot riveting welding equipment to solve the problems mentioned in the background technology. The utility model has a novel structure. In use, the workpiece is limited and fixed on the limiting seat and the limiting frame. The fixing holes are distributed at the bottom of the limiting seat. Later, the exhaust fan blows air upward, and the airflow quickly cools down the welded workpiece, thereby facilitating the quick removal of the workpiece later.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulse servo hot riveting welding device, comprising a cabinet, wherein a fixing component is fixedly installed inside the cabinet, the fixing component comprising a fixing seat, the fixing seat having a fixing hole and a threaded hole, a threaded post being rotatably installed inside the threaded hole, a fixing nut being fixed at one end of the threaded post, a limiting seat being movably installed on the top of the fixing seat, a limiting bracket being movably installed on the side of the limiting seat, and a fixing post being welded to the bottom of the limiting seat, the fixing post being movably installed inside the fixing hole.

[0006] Furthermore, a limiting hole is formed on the fixed post, and a limiting post is movably installed inside the limiting hole, with one end of the limiting post fixed to the threaded post.

[0007] Furthermore, a connecting hole is provided between the fixing holes, the connecting hole is aligned and cooperates with the limiting hole, and the connecting hole slides in contact with the limiting post.

[0008] Furthermore, the limiting seat has a mounting hole on its side, and a tension mechanism is fixed inside the mounting hole. One end of the tension mechanism is fixed with a movable column.

[0009] Furthermore, a slider is welded to one end of the movable column, a limit block is welded to the side of the slider, and a support mechanism is fixed to the side of the slider.

[0010] Furthermore, a sliding groove is formed on the inner wall of the limiting frame, the sliding groove slides in contact with the slider, and a limiting groove is formed on the inner wall of the sliding groove, the limiting groove cooperates with the limiting block.

[0011] Furthermore, a fixing box is fixed inside the cabinet, and the fixing box is fixed to the bottom of the fixing base.

[0012] Furthermore, a fixing frame is fixed inside the fixing box, and an exhaust fan is fixed between the fixing frames, with the exhaust fan cooperating with the fixing holes.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this pulse servo hot riveting welding equipment, the workpiece is fixed on the limit seat and limit frame during use. The fixing holes are distributed at the bottom of the limit seat.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a pulse servo hot riveting welding equipment, including a cabinet 1. A fixing component is fixedly installed inside the cabinet 1. The fixing component includes a fixing seat 2. The fixing seat 2 has a fixing hole 5 and a threaded hole 3. A threaded post 11 is rotatably installed inside the threaded hole 3. A fixing nut 4 is fixed to one end of the threaded post 11. A limiting seat 6 is movably installed on the top of the fixing seat 2. A limiting bracket 7 is movably installed on the side of the limiting seat 6. A fixing post 8 is welded to the bottom of the limiting seat 6. The fixing post 8 is movably installed inside the fixing hole 5. A limiting hole 9 is opened on the fixing post 8. A limiting post 10 is movably installed inside the limiting hole 9. One end of the limiting post 10 is fixed to the threaded post 11. After the threaded post 11 is rotatably installed inside the threaded hole 3, the threaded post 11 achieves the limiting and fixing of the limiting post 10. The upper and lower limits of the fixing post 8 are achieved by the limiting post 10.

[0025] In this embodiment, a connecting hole 18 is provided between the fixing holes 5. The connecting hole 18 is aligned and cooperates with the limiting hole 9. The connecting hole 18 slides in contact with the limiting post 10. An installation hole 12 is provided on the side of the limiting seat 6. A tension mechanism 17 is fixed inside the installation hole 12. A movable post 13 is fixed to one end of the tension mechanism 17. A slider 14 is welded to one end of the movable post 13. A limiting block 15 is welded to the side of the slider 14. A support mechanism 16 is fixed to the side of the slider 14. Both the tension mechanism 17 and the support mechanism 16 are spring structures. The support mechanism 16 pushes the limiting frame 7 to move downward. The descent of the limiting frame 7 completes the clamping and fixing of the workpiece.

[0026] In this embodiment, the inner wall of the limiting frame 7 has a sliding groove, which slides in contact with the slider 14. The inner wall of the sliding groove has a limiting groove, which cooperates with the limiting block 15. The cabinet 1 has a fixed box 19 inside, which is fixed to the bottom of the fixed base 2. The fixed box 19 has a fixed frame 20 inside, and an exhaust fan 21 is fixed between the fixed frames 20. The exhaust fan 21 cooperates with the fixing holes 5. The fixing holes 5 are distributed at the bottom of the limiting base 6. The fixing holes 5 blow air upwards to facilitate rapid cooling of the position after hot riveting and welding.

[0027] The internal cabinet 1 of this device includes an existing pulse hot riveting welding device, which is a mature technology that can be directly used inside this device. During use, the limiting seat 6 is installed in the fixing hole 5 at the desired position via the fixing post 8. After the fixing post 8 is installed, the limiting post 10 is installed in the threaded hole 3 at the corresponding position. The limiting post 10 slides into the limiting hole 9 from the connecting hole 18, thus limiting the upper and lower positions of the fixing post 8. After the limiting seat 6 is fixed, the workpiece is installed on top of the limiting seat 6. During workpiece installation, the limiting frame 7 moves horizontally via the movable post 13, and simultaneously, the limiting frame 7 cooperates with the sliding groove via the slider 14. The vertical adjustment is achieved. After the limit frame 7 is adjusted upward, the workpiece is placed on the limit seat 6. The limit frame 7 is released and the elastic limit frame 7 of the support mechanism 16 presses and fixes the workpiece downward. After the movable column 13 moves horizontally with the limit frame 7, it completes the horizontal limit adjustment of the position of the limit frame 7 according to the width or length of the workpiece to meet the use in different situations. After hot riveting welding, the exhaust fan 21 blows air upward. The airflow moves upward through the fixing hole 5 and quickly cools the high temperature position after welding. The hot riveting welding equipment is equipped with a pulse heating box. The pulse heating box can complete the rapid heating. The pulse heating machine is an existing device and can be directly added to this device.
