Description

Technical Field

[0001] The utility model relates to the technical field of steel welding devices, in particular to a positionable welding device for steel processing. Background Art

[0002] Laser welding machine, also often called laser welding machine, laser welding machine, is one of the commonly used equipment for steel processing and welding. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool.

[0003] When the handheld laser welding machine is in use, since the movement of the welding gun is manually operated, it is not easy to align the welding gun with the joint angle of the steel when welding the joint angles of two steel materials. Therefore, a positioner that can assist in positioning the end of the welding gun is installed on the outside of the welding gun. This positioner consists of a sleeve and two arc-shaped limit plates symmetrically fixed to the sleeve. The sleeve is connected to the outside of the welding gun, and the two arc-shaped limit plates are symmetrically distributed on both sides of the end of the welding gun. When in use, the two arc-shaped limit plates are pressed against the two steel materials to align the end of the welding gun with the joint angle of the two steel plates, thereby achieving efficient welding of the joint angle of the steel materials.

[0004] However, in actual use, since the two arc-shaped limit plates of the positioner are fixed in position, the positioner and the welding gun are fixedly installed relative to each other, the holding angle of the welding gun is fixed during use, and different users have different angle habits when using the welding gun. The fixed holding angle of the welding gun results in poor flexibility in use and is not convenient for adapting to the angle habits of different users. Based on this, a positionable welding device for steel processing is provided. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 4 In an embodiment of the present invention, a positionable welding device for steel processing includes a welding gun 1, a front end outer side of the welding gun 1 is provided with a positive angle positioning component 2, and the positive angle positioning component 2 is used to realize the alignment operation between the front end of the welding gun 1 and the positive angle joints of two steel plates;

[0030] The external corner positioning assembly 2 includes an adjustable positioning unit and a locking unit;

[0031] Through the self-adjustment of the adjustable positioning unit, the welding gun 1 with different hand-held angles can be aligned with the external corner joints of the two steel plates;

[0032] The locking unit is used to realize the locking operation of the adjustable positioning unit;

[0033] The adjustable positioning unit includes a sleeve 201, a fixing seat 202, an arc-shaped positioning piece 203, and a rotating shaft 204;

[0034] The fixing base 202 is symmetrically fixed to both sides of the outer wall of the sleeve 201, and the rotating shaft 204 is fixed to one end of the arc-shaped positioning piece 203. The two arc-shaped positioning pieces 203 are rotatably connected to the two fixing bases 202 through the rotating shaft 204.

[0035] The sleeve 201 is sleeved and installed on the outside of the front end of the welding gun 1. Two arc-shaped positioning pieces 203 are symmetrically distributed on both sides of the front end of the welding gun 1. The two arc-shaped positioning pieces 203 are pressed against the two steel surfaces to achieve alignment between the front end of the welding gun 1 and the outer corner joints of the two steel plates.

[0036] The two arc-shaped positioning pieces 203 are rotated and adjusted to achieve different hand-held angles of the welding gun 1;

[0037] The locking unit includes a gear 205, a locking outer gear cylinder 206, a limit block 207, a return spring 208, a telescopic ring groove 209, and a limit sliding groove 210;

[0038] The telescopic ring groove 209 is formed at the rear end of the outer side of the sleeve 201. The limiting sliding groove 210 is formed at the rear end of the sleeve 201 and is connected to the telescopic ring groove 209. The return spring 208 is sleeved on the inner side of the telescopic ring groove 209. The locking outer gear cylinder 206 is sleeved on the outer side of the sleeve 201 and extends to the inner side of the telescopic ring groove 209 and is tightly fitted with one end of the return spring 208.

[0039] The limiting block 207 is fixed to the inner side of the locking outer gear cylinder 206 and is slidably connected to the limiting slide groove 210. The limiting block 207 cooperates with the limiting slide groove 210 to limit the rotation of the locking outer gear cylinder 206.

[0040] The rotating shaft 204 passes through both ends of the fixing seat 202 and is fixedly connected to the gear 205. The two gears 205 are meshed with the locking outer gear cylinder 206. The locking outer gear cylinder 206 is used to synchronously lock the two gears 205, so as to realize the locking operation of the two arc-shaped positioning pieces 203.

[0041] The inner wall diameter of the sleeve 201 matches the outer wall diameter of the front end of the welding gun 1. A mounting screw hole for installing a fastening screw is opened on the top of the outer wall of the sleeve 201, and two arc-shaped positioning pieces 203 are symmetrically distributed with the mounting screw hole as the center.

[0042] In this embodiment, when the welding gun 1 is used to weld the external corner of the steel plate, the external corner positioning assembly 2 can be used to assist the welding gun 1 in aligning its front end with the external corner of the steel plate. The operation steps are as follows:

[0043] Sleeve the sleeve 201 from the front end of the welding gun 1 to the outside of the front end of the welding gun 1, and connect it to the mounting screw hole with a screw and tighten it through the mounting screw hole to fit tightly with the outer wall of the welding gun 1, thus completing the installation and fixation of the male angle positioning component 2 and the welding gun 1;

[0044] Afterwards, during welding, it is only necessary to make the two arc-shaped positioning pieces 203 fit the surfaces of the two steel plates to achieve alignment between the front end of the welding gun 1 and the outer corner joints of the two steel plates;

[0045] During this process, the angles of the two arc-shaped positioning pieces 203 can be adjusted, so that the holding angle of the welding gun 1 can be changed to different angles (it should be noted that the holding angle can be understood as the angle between the welding gun 1 and the horizontal surface. For example, when the two arc-shaped positioning pieces 203 are symmetrical with the welding gun 1 as the center, when welding the outer corners of two steel plates, the angle between the welding gun 1 and the horizontal surface is 45 degrees. By adjusting the two arc-shaped positioning pieces 203 to different angles, the holding angle of the welding gun 1 can be changed between 0-90 degrees). The outer teeth of the locking outer gear cylinder 206 are finally separated from the gear 205, and the angle locking of the arc-shaped positioning piece 203 is released. Then, the angle of the arc-shaped positioning piece 203 can be adjusted. After the two arc-shaped positioning pieces 203 are adjusted to the appropriate angles, the pressing on the locking outer gear cylinder 206 can be released. The locking outer gear cylinder 206 will be reset under the elastic force of the reset spring 208, and the outer teeth of the locking outer gear cylinder 206 will mesh with the two gears 205, thereby achieving the angle fixing of the two arc-shaped positioning pieces 203.

[0046] The coordination of the above-mentioned multiple parts can further improve the flexibility of the use of the welding gun 1 and better adapt to the operating habits of different users.

[0047] Please refer to Figures 1 to 4 The rear end of the locking outer gear cylinder 206 extends and protrudes to the rear end of the sleeve 201. The inner side of the locking outer gear cylinder 206 is formed with an inner ring that slides with the telescopic ring groove 209. The inner ring fits one end of the return spring 208, and the other end of the return spring 208 fits the inner wall end face of the telescopic ring groove 209.

[0048] In this embodiment, it should be noted that the portion of the locking outer gear cylinder 206 protruding from the rear end of the sleeve 201 has a smooth surface. Thus, when the locking outer gear cylinder 206 moves toward the front end, the smooth surface of the locking outer gear cylinder 206 aligns with the gear 205, thereby releasing the lock on the gear 205.

[0049] The return spring 208 is always in a compressed state, that is, the return spring 208 always exerts a squeezing force toward the rear end on the locking outer gear cylinder 206 through the inner ring, so that the locking outer gear cylinder 206 can maintain a stable state.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
