[0001] This invention relates to the field of automotive parts welding equipment technology, and in particular to a welding fixture and its welding method. Background Technology

[0002] Welding is a manufacturing technique that uses heat or pressure to achieve atomic bonding of materials to achieve permanent connection. Welding fixtures are clamps and devices used to fix and position workpieces during the welding process to ensure welding accuracy and efficiency. Welding is used to firmly connect components and is used to manufacture, repair and assemble various structures. It is mainly used in many industrial fields such as aerospace, automobile manufacturing, construction, shipbuilding, electronics and petrochemicals.

[0003] The existing welding fixtures are too limited in function. When welding the inner walls of automotive parts, they cannot directly and accurately move the welding head to the welding position on the inner wall of the automotive parts. Repeated adjustments and observations are required, which greatly reduces work efficiency. At the same time, during long-term welding, the welding head often vibrates, which reduces the welding effect and is prone to damaging the automotive parts. Summary of the Invention

Buffer springs are fitted onto the outer walls of the buffer rods near their respective contact blocks, with one end of each spring fixedly connected to its corresponding limiting ring and the other end fixedly connected to the inner wall of the limiting ring. The angle adjustment clamping assembly includes a clamping base slidably connected to two tracks. The clamping base can be fixed to the two tracks with bolts. A fixing ring is fixedly connected to the upper side of the clamping base, and an adjusting ratchet is slidably connected inside the fixing ring.

[0006] In a preferred embodiment, a detection frame is fixedly connected to the side of the welder body near the buffer frame, the buffer frame is located inside the detection frame, a sensing ring is provided at the end of the detection frame away from the welder body, and an alarm is provided on the upper side of the welder body.

[0008] In a preferred embodiment, the two tracks are provided with the same movable base, which is fixed to the two tracks by bolts. Two lifting cylinders are provided at equal intervals on the upper side of the movable base. The telescopic ends of the two lifting cylinders are provided with the same setting platform. A slide plate is fixedly connected to the upper side of the setting platform. Two fixing plates are fixedly connected at equal intervals on the upper side of the slide plate. The two fixing plates are connected to the same lead screw on opposite sides by bearings. A sliding base is sleeved on the outer wall of the lead screw. The sliding base slides on the slide plate. The welding machine body is provided on the upper side of the sliding base. A moving motor is provided at one end of the slide plate. The drive end of the moving motor is connected to one end of the lead screw through a coupling.

[0009] In a preferred embodiment, a rotating hole is provided on one side of the clamping base, and a rotating shaft is connected to the inside of the rotating hole via a bearing.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] The welding fixture disclosed in this invention is mainly applied to scenarios where existing welding fixtures have limited functionality, resulting in inaccurate positioning and low efficiency in welding the inner walls of automotive parts, and the welding head is prone to vibration, affecting quality and safety.

[0026] Reference Figures 1-5 A welding fixture includes a workbench 3. Two tracks 1 are equally spaced on the upper side of the workbench 3. Two angle adjustment clamping components 4 are equally spaced on one end of the two tracks 1. The same accessory body 5 is placed inside the two angle adjustment clamping components 4. A positioning and anti-shake welding component 2 is provided on the other end of the two tracks 1. The positioning and anti-shake welding component 2 includes a welder body 210. A welding head 214 is provided on one side of the welder body 210. A contact sleeve 218 is provided on the outer wall of the welding head 214. A buffer frame 220 is fixedly connected to the side of the welder body 210 near the welding head 214. The welding head 214 is located inside the buffer frame 220.

[0027] In this invention, a buffer ring 219 is fixedly connected to one end of the buffer frame 220 away from the welder body 210. Multiple buffer holes are equally spaced on the outer wall of the buffer ring 219. Buffer rods 221 are slidably connected inside the multiple buffer holes. Contact blocks 222 are fixedly connected to one end of the multiple buffer rods 221 near the welding head 214. The multiple contact blocks 222 are pressed into contact with the contact sleeve 218.

[0028] In this invention, a plurality of buffer rods 221 are fixedly connected to the outer wall of one end near the corresponding contact block 222, and a buffer spring 223 is sleeved on the outer wall of one end of the plurality of buffer rods 221 near the corresponding contact block 222. One end of the plurality of buffer springs 223 is fixedly connected to the corresponding limit ring 224, and the other end of the plurality of buffer springs 223 is fixedly connected to the inner wall of the buffer ring 219.

[0029] In this invention, a detection frame 216 is fixedly connected to the side of the welder body 210 near the buffer frame 220. The buffer frame 220 is located inside the detection frame 216. A sensing ring 215 is provided at the end of the detection frame 216 away from the welder body 210. An alarm 211 is provided on the upper side of the welder body 210.

[0030] In this invention, a perforated groove plate 212 is fixedly connected to one side of the welding device body 210. A movable plate 207 is slidably connected inside the perforated groove plate 212. The movable plate 207 can be fixed to the perforated groove plate 212 by bolts. An adjustment hole is provided at the end of the movable plate 207 away from the perforated groove plate 212. A movable rod 203 is slidably connected inside the adjustment hole. The movable rod 203 can be fixed to the movable plate 207 by bolts. A positioning hole is provided on one side of the movable rod 203. A positioning rod 206 is slidably connected inside the positioning hole. The positioning rod 206 can be fixed to the movable rod 203 by bolts. The positioning rod 206 and the welding point of the welding head 214 are located on the same horizontal line.

[0031] In this invention, a single movable base 205 is provided on two tracks 1. The movable base 205 can be fixed to the two tracks 1 by bolts. Two lifting cylinders 204 are equally spaced on the upper side of the movable base 205. The telescopic ends of the two lifting cylinders 204 are provided with a single setting platform 202. A sliding plate 208 is fixedly connected to the upper side of the setting platform 202. Two fixing plates 209 are equally spaced fixedly connected to the upper side of the sliding plate 208. The two fixing plates 209 are connected to the same lead screw 213 on opposite sides via bearings. A sliding base 217 is sleeved on the outer wall of the lead screw 213. The sliding base 217 slides on the sliding plate 208. The welding device body 210 is located on the upper side of the sliding base 217. A moving motor 201 is provided at one end of the sliding plate 208. The driving end of the moving motor 201 is connected to one end of the lead screw 213 via a coupling.

[0032] Specifically, after the required welding component body (5) is fixed, the moving base 205 is moved and the lifting cylinder 204 is used to adjust the welding machine body 210 to a suitable position. Then, the moving motor 201 is used to rotate the lead screw 213, thereby driving the sliding base 217 to move the welding machine body 210 and the welding head 214 to the welding point inside the component body 5, and then welding is performed.

[0033] In specific application scenarios, after the required welding component body (5) is fixed, the welding point position of the welding head 214 can be synchronously adjusted through the positioning rod 206. This allows the precise position of the welding head 214 and the welding point to be clearly seen from the outside of the component body 5. Under this effect, there is no need for traditional repeated debugging and observation, which greatly improves work efficiency and ensures the accuracy of the welding position. Since the positioning rod 206, the movable rod 203, and the movable plate 207 can all slide, they can adapt to different models of component bodies 5 and will not interfere with the working process. During the welding process, multiple buffers are used to adjust the welding position. The functions of the spring 223 and the contact block 222 reduce vibration of the welding head 214 during the welding process, thereby improving the stability and effect of the welding work and preventing damage to the component body 5. When the welding head 214 vibrates violently due to internal factors of the component body 5, the buffer rod 221 overcomes the effect of the buffer spring 223 and contacts the sensing ring 215, thereby triggering the alarm 211 to notify the staff to stop the work and carry out maintenance. This avoids damage to the welding head 214 and the component body 5 due to the deviation of the welding head 214, and reduces maintenance costs.

[0034] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the angle-adjustable clamping assembly 4 includes a clamping base 404, which is slidably connected to two rails 1. The clamping base 404 can be fixed to the two rails 1 by bolts. A fixing collar 401 is fixedly connected to the upper side of the clamping base 404, and an adjusting ratchet 402 is slidably connected inside the fixing collar 401.

[0035] In this invention, a rotating hole is provided on one side of the clamping base 404, and a rotating shaft 405 is connected inside the rotating hole through a bearing. A brake ratchet 403 is fixedly connected to the outer wall of the rotating shaft 405 inside the clamping base 404. The brake ratchet 403 meshes with an adjusting ratchet 402. An adjusting motor 406 is fixedly connected to one side of the clamping base 404, and the drive end of the adjusting motor 406 is connected to one end of the rotating shaft 405 through a coupling.

[0036] In this invention, multiple L-shaped plates 411 are fixedly connected to the inner wall of the adjusting ratchet 402 at equal intervals. A setting plate 408 is fixedly connected to the outer wall of the multiple L-shaped plates 411 respectively. Two support rods 409 are slidably connected to the interior of the multiple setting plates 408 at equal intervals. One end of the support rod 409 located on the same setting plate 408 is fixedly connected to the same clamping plate 407. Threaded holes are opened on one side of the multiple setting plates 408 respectively. Clamping screws 410 are screwed into the multiple threaded holes respectively. The other end of the clamping screws 410 is connected to the corresponding clamping plate 407 through a bearing.

[0037] Specifically, during use, the accessory body 5 is placed inside the two fixing collars 401, and then the corresponding clamping plates 407 are clamped and fixed by rotating the multiple clamping screws 410. During the welding process, the corresponding rotating shafts 405 are driven by the two adjusting motors 406 to rotate the corresponding brake ratchet 403. Under the rotation of the two brake ratchet 403, the corresponding adjusting ratchet 402 simultaneously drives the accessory body 5 to rotate, thereby improving the integrity of the welding work.

[0038] In specific application scenarios, during use, the support rod 409 ensures that the clamping plate 407 stably clamps the accessory body 5 while maintaining stable movement during adjustment. The clamping screw 410 allows the clamping plate 407 to adaptably clamp accessory bodies 5 with different inner diameters. Furthermore, since the two angle-adjustable clamping components 4 can slide along the two tracks 1, the distance between them can be adjusted, thus accommodating accessory bodies 5 of different lengths and greatly improving work flexibility.

[0039] A method of using a welding fixture, comprising the following steps:

[0040] Step 1: In use, the part body (5) to be welded is first clamped and fixed by the two angle-adjustable clamping components (4). (During this process, the part body 5 is placed inside the two fixing collars 401. Then, by rotating the multiple clamping screws 410, the corresponding clamping plates 407 clamp and fix the part body 5. Due to the function of the support rod 409, the clamping plates 407 can stably clamp the part body 5 while ensuring that the clamping plates 407 can move stably during the adjustment process. The clamping screws 410 allow the clamping plates 407 to adapt to clamping the part body 5 with different inner diameters. Since the two angle-adjustable clamping components 4 can slide along the two tracks 1, the distance between them can be adjusted. This allows for the placement of part bodies 5 of different lengths, greatly improving the flexibility of the work.)

[0041] Step 2: After the component body (5) to be welded is fixed, the inner wall of the component body (5) to be welded is welded by the positioning anti-shake welding assembly (2). (In this process, the moving base 205 is moved and the lifting cylinder 204 is used to adjust the welding machine body 210 to a suitable position. Then, the moving motor 201 rotates the lead screw 213, thereby driving the sliding base 217 to move the welding machine body 210 and the welding head 214 to the welding point inside the component body 5. The welding point position of the welding head 214 can be synchronized by the positioning rod 206, so that the precise position of the welding head 214 and the welding point can be clearly seen from the outside of the component body 5. Under this action, there is no need for traditional repeated debugging and observation, which greatly improves the work efficiency and ensures the accuracy of the welding position.) The positioning rod 206, the movable rod 203, and the movable plate 207 are all sliding, thus adapting to different models of component bodies 5 without interfering with the working process. During welding, the welding head 214 is made less shaky by the action of multiple buffer springs 223 and contact blocks 222, thereby improving the stability and effect of welding work while preventing damage to the component body 5. When the welding head 214 is severely displaced and shaken due to internal factors of the component body 5, the buffer rod 221 overcomes the action of the buffer springs 223 and contacts the sensing ring 215, thereby triggering the alarm 211 to notify the staff to stop the work and carry out maintenance, thus avoiding damage to the welding head 214 and the component body 5 due to the displacement of the welding head 214 and reducing maintenance costs.

[0042] Step 3: During the welding process, the welding position can be changed by rotating the part body (5) to be welded again through the angle adjustment clamping assembly (4). (During this process, the corresponding rotating shaft 405 is driven by the two adjustment motors 406 to rotate the corresponding brake ratchet 403. Under the rotation of the two brake ratchet 403, the corresponding adjustment ratchet 402 drives the part body 5 to rotate at the same time, thereby improving the integrity of the welding work.)

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
