DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The present application embodiment discloses a fixing structure for welding mechanical parts. Figure 1-3 A fixed structure for welding mechanical parts includes a base 1, which is installed on the workbench of a welding machine through the base 1, or placed on the ground for overall support when manually welding parts. A support plate 2 is installed in the middle of the base 1, and the support plate 2 is used to support the welding point of the flat workpiece to prevent the welding part from falling under the action of gravity and affecting the welding effect. Both sides of the support plate 2 on the base 1 are installed with moving components 3, and the moving component 3 includes a slide 302 slidably installed on the base 1, and the slide 302 can move along the X-axis. By changing the distance between the two slides 302, it can adapt to the welding of parts of different specifications. A translation fixing component 4 is installed on the slide 302, and the translation fixing component 4 includes a fixed seat 401 slidably installed on the slide 302. The fixed seat 401 can move along the Y axis, a fixing part 403 is installed on the fixing seat 401, and the fixing part 403 can move along the Z axis, and the fixing part 403 cooperates with the fixing seat 401 to realize the extrusion and fixation of the workpiece, and a rotating fixing component 5 is also installed on the slide 302, and the rotating fixing component 5 includes a hollow chuck 501 rotatably installed on the slide 302, and the hollow chuck 501 is located above the fixing seat 401, and the rod parts are clamped by the hollow chuck 501, and the hollow chuck 501 is connected to the fixing seat 401 through a transmission component, and the linear movement of the fixing seat 401 is converted into the rotational movement of the hollow chuck 501 through the transmission component, so as to realize the horizontal movement of the parts when a single driving source completes the plane welding and the rotation of the parts when the annular surface welding is completed, thereby improving the overall applicability.

[0026] Reference Figure 2A guide groove is provided on the base 1, and a double-headed screw 301 is rotatably installed at the bottom of the base 1. The lower ends of the two slides 302 are slidably installed in the guide groove and are threadedly connected to the corresponding ends of the double-headed screw 301. The slide 302 is driven to move by the double-headed screw 301, and the two slides 302 are moved closer to and away from each other to adapt to parts of different specifications.

[0027] Reference Figure 1 A guide assembly 7 is also installed on the base 1, and the guide assembly 7 includes two guide groove plates 702 fixedly installed at the end of the base 1. A slide groove is opened on the side where the two guide groove plates 702 are close to each other, and a guide rod 701 is installed in the slide groove. The guide rod 701 passes through the two fixed seats 401 and is slidably connected with the fixed seats 401. The two fixed seats 401 are connected by the guide rod 701. While keeping the two fixed seats 401 moving synchronously, the fixed seats 401 can also slide along the guide rod 701.

[0028] Reference Figure 2 A connecting rod 402 is rotatably installed on the slide 302, and the end of the connecting rod 402 passes through the fixed seat 401 and is transmission-connected to the fixed seat 401. One of the connecting rods 402 is installed with a thread and is threadedly connected to the corresponding fixed seat 401. The end of the connecting rod 402 with a thread passes through the slide 302 and is connected to a driving motor 6. The driving motor 6 drives the connecting rod 402 to rotate, so that the corresponding fixed seat 401 moves, and the guide rod 701 is used to pull the other fixed seat 401 to move, so as to keep the synchronous movement of the fixed seats 401 on both sides, so as to avoid deviation in movement due to differential speed, which affects the welding effect.

[0029] Reference Figure 3 The fixing member 403 includes a plurality of threaded rods 4032 threadedly mounted on the fixing seat 401, and a same pressing plate 4031 is rotatably mounted on the lower ends of the plurality of threaded rods 4032. By twisting the threaded rods 4032, the pressing plate 4031 moves downward, so that the pressing plate 4031 and the fixing seat 401 clamp and fix the parts that need to be plane welded.

[0030] Reference Figure 1 The transmission components include a gear 502 and a rack 503. The gear 502 is fixedly sleeved on the hollow chuck 501. The rack 503 is fixedly installed on the rear side of the fixed seat 401. The rack 503 is meshed with the gear 502. The rack 503 is driven by the fixed seat 401 to move and drive the gear 502 to rotate, thereby driving the gear 502 and the hollow chuck 501 to rotate, so that the parts that need to be annularly welded rotate.

[0031] The implementation principle of a fixing structure for welding mechanical parts in the embodiment of the present application is as follows:

[0032] By rotating the double-headed screw 301, the slide 302 is driven to move in the guide groove of the base 1 along the Y-axis direction, so as to adjust the distance between the two slides 302 to adapt to parts of different specifications. For parts that need to be welded on a plane, the degree of pressure of the pressing plate 4031 can be adjusted by twisting the threaded rod 4032 to ensure that the parts are firmly fixed. For parts that need to be welded on a ring surface, the parts are fixed on the hollow chuck 501. After the parts are firmly fixed, the welding operation can be performed, and the control is driven by the drive motor 6 to drive the threaded connecting rod 402 to rotate, thereby driving the guide rod 701 to slide. Since the guide rod 701 connects the two fixed seats 401, the other fixed seat 401 will also move synchronously. At the same time, the fixed seat 401 moves to drive the rack 503 to move, and the drive gear 502 rotates, thereby driving the hollow chuck 501 to rotate. According to the welding requirements, manual or automatic welding machine tools can be selected to weld the parts. After the welding is completed, the welded parts are disassembled and necessary cleaning and maintenance are performed.
