Description

Technical Field

[0001] The utility model belongs to the technical field of exothermic welding, in particular to an exothermic welding fixture. Background Art

[0002] Exothermic welding is a simple, efficient, and high-quality metal joining process. When the exothermic welding fixture clamps and fixes the exothermic welding mold, if the distance between the two clamping plates and the exothermic welding mold is large, the distance between the two clamping plates is adjusted by rotating the thread, and the adjustment efficiency is low, which reduces the convenience of using the exothermic welding fixture.

[0003] In the related art, a search found that a Chinese patent document (authorization announcement number CN220407689U) discloses an exothermic welding fixture, comprising two fixed plates for fixing to an exothermic welding mold, a horizontal rotating plate fixed to the middle of the side of the fixed plate away from the exothermic welding mold, the two rotating plates being rotatably connected, a gripping tube movably mounted on the end of the rotating plate away from the fixed plate, and a movable arc rod and a limiting sleeve fixed to the end of the two rotating plates away from the fixed plate, respectively, the upper end surface of the movable arc rod having a plurality of equidistant positioning holes, the movable arc rod inserted into the end of the limiting sleeve, the upper end surface of the limiting sleeve provided with a positioning pin, the positioning pin inserted into the limiting sleeve and plugged into the positioning pin at the corresponding position on the movable arc rod. The utility model has a reasonable structure and can be locked on the fixture, which is highly secure. However, the fixture does not consider that when the distance between the two clamping plates and the exothermic welding mold is large, the distance between the two clamping plates can be shortened by rotating the screw thread to clamp the exothermic welding mold, resulting in low adjustment efficiency and reduced convenience of use of the exothermic welding fixture. Utility Model Content

[0004] The purpose of the utility model is to provide an exothermic welding fixture to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an exothermic welding fixture, comprising an exothermic welding mold body and a clamping assembly and a fixing plate for clamping and fixing the exothermic welding mold body, the clamping assembly and the fixing plate are arranged on both sides of the exothermic welding mold body, the side of the fixing plate is fixedly connected to a connecting plate, the side of the connecting plate is fixedly connected to a support plate, the end face of the support plate is fixedly connected to a limiting plate, an iron movable plate is arranged on the side of the limiting plate, the side of the movable plate is embedded in the supporting plate and is slidably connected, a through groove is provided on the top surface of the movable plate, the inner wall of the through groove of the movable plate is slidably connected to the limiting rod, the top surface of the limiting rod is fixedly connected to a magnetic plate, the top surface of the support plate is provided with a plurality of through grooves for the limiting rod to be inserted, and the clamping assembly is arranged on the outer wall of the movable plate.

[0006] Preferably, the bottom surface of the magnetic plate is magnetically connected to the movable plate, and the clamping assembly includes a threaded plate and a clamping plate.

[0012] Preferably, the end surface of the threaded rod is fixedly connected with a rotating block.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] The exothermic welding fixture provides a clamping and fixing effect on the exothermic welding mold body through the fixing plate and the clamping plate included in the clamping assembly. The distance between the fixing plate and the clamping plate is usually adjusted by a threaded connection. The adjustment efficiency is low, and it is not convenient to use when the distance between the fixing plate and the clamping plate is large when the distance between the fixing plate and the clamping plate is large, which reduces the convenience of using the exothermic welding fixture. By moving the movable plate along the path of the support plate, the distance between the fixed plate and the clamping plate can be conveniently adjusted during the transmission process, which is suitable for the clamping and fixing requirements of the exothermic welding mold body and improves the convenience of using the exothermic welding fixture. The limit rod is respectively passed through the movable plate and the support plate to fix the relative position of the movable plate and the support plate. At the same time, the magnetic plate is magnetically connected to the movable plate to improve the structural stability of the components of the exothermic welding fixture.

[0015] The exothermic welding fixture manually rotates the rotating block to rotate the threaded rod along the threaded path of the threaded plate. The distance between the clamping plate and the fixed plate is further shortened during the transmission process, so that the clamping plate and the fixed plate can accurately clamp and fix the exothermic welding mold body. The fixed bearing is fixed to the rotation position of the rotating rod, and provides conditions for the relative rotation of the threaded rod and the clamping plate during the transmission process, preventing relative friction between the clamping plate and the exothermic welding mold body, thereby preventing surface wear of the exothermic welding fixture and the exothermic welding mold body, extending the service life of the exothermic welding fixture, and making the fixed nut abut against the threaded plate when moving along the threaded path of the threaded rod. Under the action of friction, the relative position of the threaded plate and the threaded rod is fixed, thereby improving the structural stability of the components of the exothermic welding fixture.

[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] In order to solve the problem that the adjustment efficiency of the spacing between the two clamping plates holding the exothermic welding mold is low when the exothermic welding fixture is used, which reduces the convenience of using the exothermic welding fixture, please refer to Figures 1 to 4The structure of the device body is as follows: it includes an exothermic welding mold body 1 and a clamping assembly 2 and a fixing plate 3 for clamping and fixing the exothermic welding mold body 1. After the exothermic welding powder inside the exothermic welding mold body 1 is ignited, the aluminum powder and copper oxide undergo a violent redox reaction, generating a large amount of heat, generating liquid copper and aluminum oxide, and the liquid copper flows into the exothermic welding mold body 1 under the action of gravity, wrapping and melting the metal surface to be welded, forming a strong welding joint, and realizing exothermic welding.

[0027] The exothermic welding mold body 1 is divided into two mutually fitting parts, the left part and the right part. The exothermic welding mold body 1 is clamped and fixed by the provided clamping assembly 2 and the fixed plate 3, so that the two parts of the exothermic welding mold body 1 are tightly fitted. The clamping assembly 2 and the fixed plate 3 are arranged on both sides of the exothermic welding mold body 1. The side of the fixed plate 3 is fixedly connected with a connecting plate 4, and the side of the connecting plate 4 is fixedly connected with a support plate 5. The end face of the support plate 5 is fixedly connected with a limiting plate 6. The side of the limiting plate 6 is provided with an iron movable plate 7. The side of the movable plate 7 is embedded in the support plate 5 for sliding connection, so that the movable plate 7 moves along the path of the support plate 5. The provided connecting plate 4 and the limiting plate 6 prevent the movable plate 7 from separating from the support plate 5 during movement, thereby improving the structural stability of the components of the exothermic welding fixture.

[0028] The top surface of the movable plate 7 is provided with a through slot, and the inner wall of the through slot of the movable plate 7 is slidably connected to the limit rod 8, so that the limit rod 8 passes through the through slot of the movable plate 7 and penetrates the movable plate 7. The top surface of the support plate 5 is provided with a plurality of through slots for the limit rod 8 to be inserted. At the same time, the limit rod 8 extends into the through slot of the support plate 5 to fix the relative position of the movable plate 7 and the support plate 5, so as to facilitate the release of the relative position fixation of the support plate 5 and the movable plate 7 by the limit rod 8. The position of the movable plate 7 is adjusted. The top surface of the limit rod 8 is fixedly connected with a magnetic plate 9, and the clamping assembly 2 It is arranged on the outer wall of the movable plate 7, and the distance between the clamping component 2 and the fixed plate 3 can be conveniently adjusted over a large range during transmission, and the distance between the clamping component 2 and the fixed plate 3 can be adjusted by preventing the threaded connection method, which has low adjustment efficiency, thereby improving the convenience of using the exothermic welding fixture. The bottom surface of the magnetic plate 9 is magnetically connected to the movable plate 7, and the magnetic plate 9 is located on the top surface of the movable plate 7 and is magnetically connected to the movable plate 7, preventing the limit rod 8 from detaching from the movable plate 7, thereby improving the relative position fixing effect of the limit rod 8 on the movable plate 7 and the support plate 5.

[0029] The clamping assembly 2 includes a threaded plate 10 and a clamping plate 16. The clamping plate 16 is arranged to contact the exothermic welding mold body 1, so that the clamping plate 16 and the fixed plate 3 cooperate to clamp and fix the exothermic welding mold body 1. The adjacent sides of the clamping plate 16 and the fixed plate 3 are in contact with the exothermic welding mold body 1. The end face of the clamping plate 16 is slidably connected to the support plate 5, so that the clamping plate 16 moves along the path of the support plate 5. The support plate 5 is arranged to prevent the clamping plate 16 from rotating, thereby improving the position movement stability of the clamping plate 16. A fixed bearing 15 is embedded and fixedly connected to the side of the clamping plate 16.

[0030] The inner ring of the fixed bearing 15 is interference fit with the rotating rod 14. The fixed bearing 15 is set to fix the rotation position of the rotating rod 14 and provide conditions for the relative rotation of the rotating rod 14 and the clamping plate 16. The end face of the rotating rod 14 is in rotational friction contact with the clamping plate 16. The end of the rotating rod 14 away from the clamping plate 16 is welded with a threaded rod 11. The threaded rod 11 is threadedly connected with a fixed nut 12. The side of the fixed nut 12 abuts against the threaded plate 10. The threaded plate 10 is threadedly connected to the threaded rod 11. The end face of the threaded plate 10 is fixedly connected to the movable plate 7. The end face of the threaded rod 11 is fixedly connected to the rotating block 13, so that the rotating block 13 rotates, thereby realizing the movement of the threaded rod 11 along the threaded path of the threaded plate 10. During the transmission process, high-precision position adjustment of the clamping plate 16 is realized, the distance between the clamping plate 16 and the fixed plate 3 is shortened, and the exothermic welding mold body 1 is clamped and fixed.

[0031] The fixed bearing 15 and the rotating rod 14 are provided to prevent relative friction between the clamping plate 16 and the exothermic welding mold body 1, prevent damage to the components of the exothermic welding fixture, and extend the service life of the exothermic welding fixture, so that the fixing nut 12 moves along the threaded path of the threaded rod 11, so that the fixing nut 12 contacts the threaded plate 10. Under the action of friction, the relative position of the threaded plate 10 and the threaded rod 11 is fixed, and the side where the fixing nut 12 and the threaded plate 10 contact each other is rough.

[0032] How it works

[0033] When using the exothermic welding fixture, the user disengages the limiting rod 8 from the supporting plate 5 and the movable plate 7, so that the movable plate 7 moves along the path of the supporting plate 5. During the transmission process, the distance between the clamping plate 16 and the fixed plate 3 is rapidly shortened in a large interval, so that the rotating block 13 rotates, and the threaded rod 11 moves along the threaded path of the threaded plate 10. During the transmission process, the clamping plate 16 and the fixed plate 3 clamp and fix the exothermic welding mold body 1.

[0034] Under the connection between the rotating rod 14 and the fixed bearing 15, conditions are provided for the relative rotation of the threaded rod 11 and the clamping plate 16. At the same time, the clamping plate 16 moves along the path of the support plate 5, so that there is no relative friction when the clamping plate 16 contacts the exothermic welding mold body 1, and the fixing nut 12 moves along the path of the threaded rod 11, so that the fixing nut 12 contacts the threaded plate 10.
