Description

Technical Field

[0001] The utility model relates to the technical field of welding guns, in particular to a high-precision laser welding gun. Background Art

[0002] The welding gun refers to the part that performs the welding operation during the welding process. It is a tool used for gas welding. It is shaped like a gun, with a nozzle at the front end, and sprays high-temperature flames as a heat source. It is flexible to use, convenient and fast, and the process is simple. The welding gun uses the high current and high voltage of the welding machine to generate heat that gathers at the end of the welding gun to melt the welding wire. The molten welding wire penetrates into the part to be welded. After cooling, the objects to be welded are firmly connected into one.

[0003] However, the problem that the existing high-precision laser welding guns are inconvenient to cooperate with protection when in use has not been solved. Since the welding gun needs to be moved during use, it is easy for the welding gun to collide with other equipment during the movement. The protection effect is not good and the welding gun is easily damaged by collision, thus affecting the use effect and life. For this reason, we propose a high-precision laser welding gun. Utility Model Content

[0004] In view of the above problems, the utility model provides a high-precision laser welding gun, which has a protective effect to prevent the laser welding gun from being easily damaged due to collision during processing, and at the same time has a detachable effect to prevent the protective structure from being damaged and inconvenient to replace.

[0005] The technical solution of the utility model is: a high-precision laser welding gun, comprising a laser welding gun body, a mounting sleeve is sleeved on the surface of the laser welding gun body, four symmetrically arranged protective plates are arranged on the surface of the mounting sleeve, the protective plates are all semi-arc-shaped plates, the protective plates are made of rubber, telescopic rods are fixed between the facing surfaces of the protective plates and the mounting sleeve, a spring is sleeved on the surface of the telescopic rod, and the two ends of the spring are respectively fixedly connected to the mounting sleeve and the protective plate.

[0006] In a further technical solution, a connecting plate located above the mounting sleeve is fixed on the surface of the laser welding gun body, and a mounting plate fixed to the mounting sleeve is threadedly connected to the connecting plate, and the mounting plate is used to cooperate with the connecting plate to limit the mounting sleeve.

[0007] In a further technical solution, buffer blocks fixed to the mounting sleeve are provided on both sides of the telescopic rod.

[0008] In a further technical solution, the buffer block is made of soft rubber material, and the buffer block is used to cooperate to improve the buffering effect of the protective plate.

[0009] In a further technical solution, the mounting sleeve is in close contact with the bottom surface of the connecting plate.

[0010] The beneficial effects of the utility model are:

[0011] 1. The installation sleeve, protective plate, telescopic rod and spring cooperate with each other to protect the laser welding gun body when in use. The protective plate protects the laser welding gun body from external force collision. At this time, the telescopic rod and spring can reduce the impact, achieving the effect of convenient protection, preventing the laser welding gun body from being inconvenient to cooperate with the protection when in use, resulting in collision with other equipment during movement, and easy damage;

[0012] 2. The connection plate and the mounting plate cooperate with each other, so that the mounting sleeve and the protective plate can be easily disassembled and maintained. The mounting sleeve drives the mounting plate to cancel the connection with the connection plate, thereby achieving the effect of easy disassembly and assembly, and preventing the mounting sleeve and the protective plate from being inconvenient to disassemble and maintain, thereby affecting the buffering effect.

[0019] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0020] Example:

[0021] like Figure 1-Figure 4As shown, a high-precision laser welding gun comprises a laser welding gun body 1, a mounting sleeve 2 is sleeved on the surface of the laser welding gun body 1, four symmetrically arranged protective plates 3 are arranged on the surface of the mounting sleeve 2, the protective plates 3 are all semi-arc-shaped plates, the protective plates 3 are made of rubber, telescopic rods 4 are fixed between the facing surfaces of the protective plates 3 and the mounting sleeve 2, a spring 5 is sleeved on the surface of the telescopic rod 4, two ends of the spring 5 are respectively fixedly connected to the mounting sleeve 2 and the protective plate 3, buffer blocks 6 fixed to the mounting sleeve 2 are arranged on both sides of the telescopic rod 4, the buffer blocks 6 are made of soft rubber, and the buffer blocks 6 are used to cooperate to improve the buffering effect of the protective plates 3.

[0022] The working principle of the above technical solution is as follows:

[0023] When a collision occurs when the laser welding gun body 1 is in use and moving, the protective plate 3 set at this time can reduce the collision caused by other equipment. At this time, the protective plate 3 is forced to move close to the laser welding gun body 1, and then the protective plate 3 can squeeze the telescopic rod 4 and the spring 5 in a contracted state. At the same time, the elastic force of the spring 5 set can adapt to reduce the impact on the protective plate 3. Then the protective plate 3 can be reset by the elastic force of the spring 5, and the buffer block 6 set can improve the buffering effect of the spring 5 to prevent the protective plate 3 from being bumped when the collision force is large. At this time, the buffer block 6 set can provide secondary buffering, which realizes the effect of convenient buffering protection, and prevents the laser welding gun body 1 from colliding with other equipment when it is in mobile use, which is inconvenient to protect and easy to be damaged, affecting the overall use feeling and life.

[0024] In another embodiment, if Figure 2 and Figure 4 As shown, a connecting plate 7 located above the mounting sleeve 2 is fixed on the surface of the laser welding gun body 1, and a mounting plate 8 fixed to the mounting sleeve 2 is internally threadedly connected to the connecting plate 7. The mounting plate 8 is used to cooperate with the connecting plate 7 to limit the mounting sleeve 2, and the mounting sleeve 2 and the bottom surface of the connecting plate 7 are in a fit state.

[0025] When it is necessary to maintain or disassemble the mounting sleeve 2 and the protective plate 3, the mounting sleeve 2 can be held and force can be applied to drive the mounting plate 8 to rotate. At this time, the mounting plate 8 can cancel the threaded connection with the connecting plate 7 during rotation, and then the protective plate 3 can be held and driven to cancel the installation of the mounting sleeve 2 with the laser welding gun body 1. At this time, the mounting sleeve 2 and the protective plate 3 can be replaced or maintained. During installation, the mounting sleeve 2 can be put on the surface of the laser welding gun body 1, and then the mounting plate 8 can be screwed together with the connecting plate 7 for installation, thereby achieving the effect of easy disassembly and maintenance, and preventing the mounting sleeve 2 and the protective plate 3 from being damaged and inconvenient to maintain, affecting the overall usage experience.

[0026] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
