Description

Technical Field

[0001] This utility model patent relates to the field of metal processing technology, and mainly to a positioning device for welding metal parts. Background Technology

[0002] Welding technology, also known as joining engineering, is an important material processing technology. Welding is a process in which the materials of the workpieces are heated or pressurized, or both, and with or without filler material, to achieve atomic bonding and form a permanent connection.

[0003] The existing patent publication number CN217452780U describes a metal plate welding equipment for shelf production. However, this equipment is difficult to adjust the angle of the metal plates during use, making it difficult for welders to adjust to a comfortable welding angle. Furthermore, after welding the two metal plates facing upwards, the plates need to be removed from the clamping plate, flipped over, and then re-fixed onto the clamping plate before welding the other side can be performed. This not only makes the operation more complicated but also reduces welding efficiency. Therefore, it is necessary to design a positioning device for metal part welding to solve the above problems. Utility Model Content

[0004] This utility model mainly provides a positioning device for welding and processing metal parts to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the following technical solution is provided: a positioning device for welding metal parts, comprising a processing table, a fixing mechanism connected to the top of the processing table, the fixing mechanism comprising a first motor connected to one side of the top of the processing table, a bidirectional lead screw connected to the drive end of the first motor and a fixing plate connected to both sides of the bidirectional lead screw, a rotating device connected to the top of the fixing plate, the rotating device comprising a fixing frame rotatably connected to the top of the fixing plate and a synchronization component connecting the two fixing frames, positioning components connected to both sides of the fixing frame, and a threaded rod connected to the top of the fixing frame;

[0006] A worm gear is connected to one side of the fixed frame, a worm is meshed with one side of the worm gear, a second motor is connected to one side of the worm, and a fixed plate is connected to one side of the second motor.

[0007] Furthermore, the synchronization component includes sleeves connected to both sides of the fixed frame away from the second motor and a slide rod slidably connected to the inner wall of the sleeve, with one side of the slide rod connected to the fixed frame close to the second motor.

[0008] Furthermore, the top of the fixed frame is provided with a threaded hole, the hole body of the threaded hole is engaged with the threaded rod, and the bottom of the threaded rod is rotatably connected to the pressure block.

[0009] Furthermore, the positioning component includes a telescopic member connected to the bottom of the fixed frame, a spring sleeved on the outer wall of the telescopic member, and a positioning plate connected to one side of the telescopic member, wherein the outer wall of the positioning plate is slidably connected to the inner wall of the fixed frame.

[0010] Furthermore, the positioning plate has a beveled edge on its inner side.

[0011] Furthermore, vertical plates are fixed on both sides of the top of the processing table, and guide rods are fixed on both sides of the vertical plates. The guide rods are slidably connected to the holes on both sides of the fixed plates.

[0012] Furthermore, a knob is fixed to the top of the threaded rod, and the outer wall of the knob is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model provides a positioning device for metal welding. A spring force causes a positioning plate to press against a metal plate, thus positioning the metal plate. Rotating a threaded rod lowers the threaded rod and pressure block, fixing the metal plate. A first motor drives a bidirectional lead screw to rotate, causing two fixed plates to move in opposite directions, aligning the two metal plates. A second motor drives a worm gear to rotate, which in turn drives a worm wheel. A synchronization assembly then synchronizes the rotation of the two fixed frames, achieving the rotation of the metal plate. This device not only facilitates the positioning and fixing of the metal plate and aligns the two plates, but also allows for adjustment of the plate angle, making welding more comfortable for workers and facilitating the flipping of the metal plate, thus improving work efficiency.

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0020] For an example, please refer to... Figure 1-2 A positioning device for welding metal parts includes a processing table 10. A fixing mechanism 20 is connected to the top of the processing table 10. The fixing mechanism 20 includes a first motor 21 connected to one side of the top of the processing table 10, a bidirectional lead screw 22 connected to the drive end of the first motor 21, and a fixing plate 23 connected to both sides of the bidirectional lead screw 22. A rotating device 30 is connected to the top of the fixing plate 23. The rotating device 30 includes a fixing frame 34 rotatably connected to the top of the fixing plate 23 and a synchronization component 35 connecting the two fixing frames 34. Positioning components 50 are connected to both sides of the fixing frame 34, and a threaded rod 40 is connected to the top of the fixing frame 34.

[0021] One side of the fixed frame 34 is connected to a worm gear 33, one side of the worm gear 33 is meshed with a worm 32, one side of the worm 32 is connected to a second motor 31, and one side of the second motor 31 is connected to a fixed plate 23.

[0022] It should be noted that, in this embodiment, the worm gear 33 and worm 32 work together to give one fixed frame 34 a self-locking function. The first motor 21 drives the bidirectional lead screw 22 to rotate, thereby causing the two fixed plates 23 to move in opposite directions. The second motor 31 drives the worm 32 to rotate, thereby driving the worm gear 33 to rotate. Then, the synchronization component 35 makes the two fixed frames 34 rotate synchronously. The synchronization component 35 connects the two fixed frames 34 to prevent the fixed frames 34 without self-locking function from rotating arbitrarily, which would make it difficult to align the metal plates.

[0023] For an example, please refer to... Figure 2 The synchronization component 35 includes a sleeve 351 connected to both sides of a fixed frame 34 away from the second motor 31 and a slide rod 352 slidably connected to the inner wall of the sleeve 351. One side of the slide rod 352 is connected to the fixed frame 34 close to the second motor 31.

[0024] It should be noted that, in the embodiment, the sleeve 351 and the slide rod 352 cooperate to make the two fixed frames 34 rotate synchronously, and the two fixed frames 34 can be moved by sliding the slide rod 352.

[0025] For an example, please refer to... Figure 1-2The top of the fixed frame 34 is provided with a threaded hole, the hole body of the threaded hole is engaged with the threaded rod 40, and the bottom of the threaded rod 40 is rotatably connected to the pressure block 41.

[0026] It should be noted that, in the embodiment, the threaded rod 40 and the pressure block 41 are lowered by rotating the threaded rod 40. When the pressure block 41 contacts the metal plate, the threaded rod 40 rotates and lowers, at which point the pressure block 41 stops rotating, thus avoiding wear on the metal plate caused by the rotation of the pressure block 41.

[0027] For an example, please refer to... Figure 2 The positioning component 50 includes a telescopic member 51 connected to the bottom of the fixed frame 34, a spring 52 sleeved on the outer wall of the telescopic member 51, and a positioning plate 53 connected to one side of the telescopic member 51. The outer wall of the positioning plate 53 is slidably connected to the inner wall of the fixed frame 34.

[0028] It should be noted that, in this embodiment, the positioning plate 53 is pressed against the metal plate by the elastic force of the spring 52, thereby achieving the positioning of the metal plate.

[0029] For an example, please refer to... Figure 2 The positioning plate 53 has an inclined edge 531 on its inner side.

[0030] It should be noted that, in the embodiment, the inclined edge 531 facilitates the metal plate to press against the positioning plate 53, thereby causing the positioning plate 53 to shrink and thus positioning the metal plate.

[0031] For an example, please refer to... Figure 2 The processing table 10 has vertical plates 11 fixed on both sides of its top, and guide rods 12 fixed on both sides of the vertical plates 11. The guide rods 12 are slidably connected to the holes on both sides of the fixed plate 23.

[0032] It should be noted that, in the embodiment, the guide rod 12 facilitates the stabilization of the fixing plate 23 and prevents the fixing plate 23 from rotating with the bidirectional lead screw 22.

[0033] The specific operation method of this utility model is as follows:

[0034] The aforementioned positioning device for welding metal parts first inserts a metal plate into a fixed frame 34. The spring force of the spring 52 causes the positioning plate 53 to press the metal plate, thereby positioning the metal plate. The threaded rod 40 is rotated to lower the threaded rod 40 and the pressure block 41, thereby fixing the metal plate. Then, the first motor 21 drives the bidirectional lead screw 22 to rotate, thereby causing the two fixed plates 23 to move in opposite directions, so that the two metal plates come into contact and align.

[0035] When the welder needs to adjust the angle to suit their needs and flip the metal plate, the second motor 31 drives the worm gear 32 to rotate, which in turn drives the worm wheel 33 to rotate. This, in turn, causes the two fixed frames 34 to rotate synchronously through the synchronization component 35, thereby realizing the rotation of the metal plate.

[0036] The embodiments described above merely illustrate the implementation methods of this application. However, those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
