Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding device for processing mechanical parts. Background Technology

[0002] Welding equipment for machining mechanical parts is mainly used to connect and fix separated metal or non-metal parts by heating, pressurizing and other methods to ensure the dimensional accuracy and structural strength of the parts. It uses tooling fixtures to accurately position the parts and avoids dimensional deviations caused by manual operation. It adopts pre-deformation or reverse deformation design to reduce thermal deformation problems during the welding process.

[0003] Chinese patent CN221494836U discloses a welding device for machining mechanical parts. The device includes a housing with an internal adjustment structure. Two electrically operated telescopic rods are fixedly mounted on the top of the housing. A clamping structure is located above the housing. A lead screw slide is mounted on the top of each telescopic rod, and a welding pen is mounted on the lead screw slide. The adjustment structure includes a fixed base, a guide rod, a sliding sleeve, a motor, a connecting shaft, a threaded rod, a threaded sleeve, a connecting rod, a first fixed plate, and a support rod. This welding device for machining mechanical parts, through its adjustment structure, allows the motor to be turned on, causing the connecting shaft to rotate. The threaded sleeve, threadedly connected to the lead screw, begins to move. With the sliding sleeve and connecting rod fixing it, the threaded sleeve does not rotate, allowing it to move stably on the lead screw. Simultaneously, the support rod at the top of the threaded sleeve moves the clamping structure, thus enabling the adjustable movement of the welding device.

[0004] The aforementioned device has the effect of controlling mechanical movement and welding. However, due to the single movement trajectory, the existing device cannot simulate real welding, resulting in poor welding effect. Furthermore, the welding process needs to meet the processing requirements of mechanical parts of different heights. Therefore, a welding device for processing mechanical parts is required. Utility Model Content

[0005] The purpose of this utility model is to provide a welding device for processing mechanical parts, so as to solve the problems of the existing device having a single welding route and being adaptable to different mechanical parts of different heights.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding device for machining mechanical parts, comprising a base and a welding head, wherein a welding mechanism is provided on the welding head; the welding mechanism includes a slide block, the slide block being fixedly installed on the upper side of the base, and a rack being fixedly installed on the lower side of the slide block, and a bracket being slidably installed on the upper side of the slide block, and a gear motor being fixedly installed in the middle of the slide block, and an mounting plate being fixedly installed on the upper side of the bracket, wherein two limiting seats are fixedly installed on the upper part of the mounting plate, a limiting shaft is slidably installed between the two limiting seats, a rotating rod is rotatably installed at one end of the limiting shaft, a rotating shaft is rotatably installed at one end of the rotating rod, a drive motor is fixedly installed on the upper side of the mounting plate, a limiting frame is fixedly installed on the output end of the drive motor, a threaded seat is fixedly installed at one end of the limiting frame, and a first bolt is threaded through the threaded seat.

[0008] Preferably, one end of the limiting shaft is fixedly connected to the welding head, and a U-shaped groove is provided on the mounting plate.

[0009] Preferably, the rotating shaft is slidably installed inside the limiting frame, and one end of the first bolt is rotatably connected to the rotating shaft.

[0010] Preferably, a positioning mechanism is provided on the upper side of the base. The positioning mechanism includes two buckles, a threaded plate is fixedly installed between the two buckles, and a worktable is slidably installed on the two buckles. A buckle seat is fixedly installed on the lower side of the worktable, and a second bolt is rotatably installed on the buckle seat.

[0011] Preferably, the buckle has a strip-shaped slot, and the workbench is slidably mounted on the two buckles through the strip-shaped slot.

[0012] Preferably, the buckle and the second bolt are located in the middle of the workbench and the threaded plate, respectively, and the second bolt is threaded onto the threaded plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) This welding device for machining mechanical parts controls the rotation of a gear motor. Benefiting from the meshing connection between the gear motor and the rack, the limit seat can move on the slide. When the drive motor is controlled to rotate, the rotating shaft will rotate under the action of the limit frame, which will drive the rotating rod to push and pull the limit shaft to move back and forth on the limit seat, thereby causing the welding head to move back and forth. The rotation radius of the rotating shaft can be changed by controlling the first bolt, thereby changing the movement range of the welding head. Combined with the longitudinal and transverse movement of the welding head, the welding joints are made denser, improving the welding effect of the mechanical parts.

[0014] 2) The welding device for processing mechanical parts controls the second bolt to move the worktable up and down relative to the threaded plate, thereby changing the height of the mechanical parts. The worktable is slidably installed between two fasteners, while ensuring that the fastener and the second bolt are centered, so that the mechanical parts remain stable when moving.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Combination Figures 1-4A welding device for machining mechanical parts includes a base 1 and a welding head 2. A welding mechanism 3 is mounted on the welding head 2. The welding mechanism 3 includes a slide 301, which is fixedly mounted on the upper side of the base 1. A rack 302 is fixedly mounted on the lower side of the slide 301, and a bracket 303 is slidably mounted on the upper side of the slide 301. A gear motor 304 is fixedly mounted in the middle of the slide 301. A mounting plate 305 is fixedly mounted on the upper side of the bracket 303. The upper part of the mounting plate 305 is fixed... Two limit seats 306 are installed, and a limit shaft 307 is slidably installed between the two limit seats 306. A rotating rod 308 is rotatably installed at one end of the limit shaft 307, and a rotating shaft 309 is rotatably installed at one end of the rotating rod 308. A drive motor 310 is fixedly installed on the upper side of the mounting plate 305. A limit frame 311 is fixedly installed on the output end of the drive motor 310. A threaded seat 312 is fixedly installed at one end of the limit frame 311, and a first bolt 313 is threaded through the threaded seat 312.

[0019] A number of teeth are fixedly installed on the output end of the gear motor 304, and the rack 302 is meshed with the teeth. One end of the limiting shaft 307 is fixedly connected to the welding head 2. A U-shaped groove is provided on the mounting plate 305. The rotating shaft 309 is slidably installed in the limiting frame 311. One end of the first bolt 313 is rotatably connected to the rotating shaft 309. In use, by controlling the rotation of the gear motor 304, the limiting seat 306 can be moved due to the meshing connection between the gear motor 304 and the rack 302. When the slide block 301 moves, the drive motor 310 rotates, causing the rotating shaft 309 to rotate under the action of the limit frame 311. This, in turn, drives the rotating rod 308 to push and pull the limit shaft 307 to reciprocate on the limit seat 306, thereby causing the welding head 2 to reciprocate. The rotation radius of the rotating shaft 309 can be changed by controlling the first bolt 313, thereby changing the movement range of the welding head 2. Combined with the longitudinal and transverse movement of the welding head 2, the welding joints are made denser, improving the welding effect of mechanical parts.

[0020] Example 2 See Figure 5 A positioning mechanism 4 is provided on the upper side of the base 1. The positioning mechanism 4 includes two buckles 401. A threaded plate 402 is fixedly installed between the two buckles 401. A worktable 403 is slidably installed on the two buckles 401. A buckle seat 404 is fixedly installed on the lower side of the worktable 403. A second bolt 405 is rotatably installed on the buckle seat 404.

[0021] The buckle 401 has a strip-shaped slot, and the worktable 403 is slidably mounted on the two buckles 401 through the strip-shaped slot. The buckle seat 404 and the second bolt 405 are located in the middle of the worktable 403 and the threaded plate 402, respectively. The second bolt 405 is threaded onto the threaded plate 402. In use, the worktable 403 is moved up and down relative to the threaded plate 402 by controlling the second bolt 405, thereby changing the height of the mechanical parts. The worktable 403 is slidably mounted between the two buckles 401, while ensuring that the buckle seat 404 and the second bolt 405 are centered, so that the mechanical parts remain stable when moving.

[0022] In actual operation, by controlling the rotation of the gear motor 304, the limit seat 306 can move on the slide 301 thanks to the meshing connection between the gear motor 304 and the rack 302. When the drive motor 310 is controlled to rotate, the rotating shaft 309 will rotate under the action of the limit frame 311, which will drive the rotating rod 308 to push and pull the limit shaft 307 to move back and forth on the limit seat 306, thereby causing the welding head 2 to move back and forth. The rotation radius of the rotating shaft 309 can be changed by controlling the first bolt 313, thereby changing the movement range of the welding head 2. With the longitudinal and transverse movement of the welding head 2, the welding of the weld joint is made denser, improving the welding effect of the mechanical parts. By controlling the second bolt 405, the worktable 403 moves up and down relative to the threaded plate 402, thereby changing the height of the mechanical parts. The worktable 403 is slidably installed between the two fasteners 401, while ensuring that the fastener 404 and the second bolt 405 are centered, so that the mechanical parts remain stable when moving.
