Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically, to an automatic calibration welding device for automotive seat frames. Background Technology

[0002] The car seat frame is the core metal frame that supports the seat. It is usually welded from high-strength steel or alloy materials and bears the functions of load-bearing, adjustment and safe fixation of the seat. Welding is the main connection method in the production of car seats, especially the connection of the seat frame. Advanced welding equipment and strict quality control ensure the robustness of the seat frame structure to meet the various needs of the car during driving.

[0003] When welding a car seat frame, the seat frame components need to be installed and aligned with the drawings. For example, the seat basin frame that makes up a car seat frame mainly includes frame side plates, crossbeams, slide rails, and adjuster brackets. Since there are usually two frame side plates, other car seat components (such as crossbeams) are set between the two frame side plates. During welding, these seat frame components need to be clamped and their welding positions aligned.

[0004] In the process of welding seat frames, rigid fixtures are generally used to clamp the workpieces. During the operation, the frame side plates and crossbeams and other accessories are first placed in the fixture and fixed. Then, the welding positions are aligned and welding can begin. However, since there is a large difference between the actual size of the seat accessories and the theoretical value, after the parts are clamped, the welding positions of some parts will be subjected to large assembly stress. During the welding process, the welding parts are easily deformed due to high temperature, which affects the dimensional accuracy of the finished product. Summary of the Invention

[0005] This invention proposes an automatic calibration welding device for automotive seat frames, which solves the technical problem in the prior art where, during the welding of automotive seat frames, the stress between the welding positions of various seat components is different due to the rigid clamping effect, which easily affects the dimensional accuracy of the finished product.

[0006] The technical solution of the present invention is as follows:

[0007] An automatic calibration and welding device for automotive seat frames includes a welding robot and a base frame. A support bracket is rotatably mounted on the base frame, and a load-bearing bracket is fixedly mounted on the support bracket. The welding robot is located on the side of the base frame. The device also includes:

[0008] The sliding frame has two sliding frames symmetrically and slidably arranged on the support bracket, and a clamping frame is slidably installed on the sliding frame;

[0009] The slide table, two slide tables are symmetrically and slidably arranged on the support bracket, and a sliding bracket is slidably arranged on the slide table. The sliding bracket can only move longitudinally along the slide table, and the sliding bracket can only move laterally.

[0010] The clamping and adjusting component is provided on the support bracket and is used to adjust the position between the frame side plates that constitute the car seat frame when clamping them.

[0011] A flexible clamping assembly is provided on the clamping frame for flexibly clamping the skeleton side plate, and adapting to the displacement of the docking position when the parts to be welded are joined together.

[0012] A beam clamping assembly is provided on the sliding bracket for clamping the beams that constitute the frame of an automobile seat.

[0013] To adjust the clamping position of the frame side plate, the clamping and adjusting assembly includes:

[0014] A bidirectional screw is rotatably mounted inside the bearing bracket. Two movable nuts are symmetrically threaded onto the bidirectional screw, and the two movable nuts are respectively fixedly connected to the two sliding frames.

[0015] The first motor is fixedly installed inside the support bracket, and its output end is fixedly connected to the bidirectional screw.

[0016] Furthermore, it also includes:

[0017] The adjusting screw is rotatably installed inside both of the sliding frames. The adjusting screw is threaded with an adjusting nut, which is fixedly connected to the clamping frame.

[0018] The adjustment knobs are rotatably mounted on both of the sliding frames, and the adjustment knobs are fixedly connected to the adjustment screws.

[0019] To clamp the frame side plates and accommodate displacement that occurs when components are joined together, the flexible clamping assembly includes:

[0020] The first driving component is installed on both of the clamping frames. A pulling frame is fixedly provided at the output end of the first driving component, and the pulling frame is slidably engaged with the clamping frame.

[0021] An outer positioning frame and an inner positioning frame are provided. Each of the pulling frames is fixedly provided with an outer positioning frame, and an inner positioning frame is slidably provided inside each of the outer positioning frames. A spring is fixedly installed between the inner positioning frame and the outer positioning frame.

[0022] Each clamping frame has a sliding abutment frame inside, the abutment frame being positioned corresponding to the inner positioning frame. An airbag is provided inside the clamping frame, and the other end of the airbag abuts against the side of the abutment frame away from the inner positioning frame.

[0023] To clamp the beam, the beam clamping assembly includes:

[0024] The outer frame and the inner frame are provided. Each of the sliding supports is equipped with the inner frame, and each of the inner frames is slidably equipped with the outer frame. Each of the outer frames has a lifting screw rotatably installed on its inner bottom wall, and each lifting screw has a lifting nut threaded onto it. The lifting nut is fixedly connected to the inner frame.

[0025] A lifting knob is rotatably mounted on each of the outer frames, and the lifting knob is fixedly connected to the lifting screw.

[0026] The sliding bracket is equipped with fastening screws to determine the relative position between the sliding bracket and the slide table.

[0027] Furthermore, it also includes mounting brackets, each of the outer frames is equipped with a mounting bracket, and two second driving members are symmetrically and fixedly arranged on the mounting bracket. The output end of the second driving member is fixedly provided with a positioning pad for abutting against the crossbeam, and an anti-slip pad is also installed inside the mounting bracket.

[0028] In order to adjust the position of the seat frame during welding, a drive motor is fixedly installed inside the base frame. Two meshing transmission gears are rotatably installed inside the base frame. The output end of the drive motor is fixedly connected to one of the transmission gears, and the other transmission gear is fixedly connected to the support bracket.

[0029] The working principle and beneficial effects of this invention are as follows:

[0030] 1. In this invention, when the first motor drives the bidirectional screw to rotate, the two moving nuts will drive the two sliding frames to move synchronously in opposite directions, thereby precisely adjusting the lateral distance between the two frame side plates. When it is necessary to adjust the longitudinal position of a single-sided clamping frame, the longitudinal position of the single-sided clamping frame can be adjusted separately by rotating the adjustment knob, thereby eliminating the assembly error of the side plates step by step and improving the alignment accuracy of the two clamping frames.

[0031] 2. In this invention, the first driving component is activated to pull the pulling frame, which in turn moves the outer positioning frame and the inner positioning frame together toward the skeleton side plate until the inner positioning frame contacts the skeleton side plate. This pushes the skeleton side plate to move until it contacts the abutment frame. At the same time, the spring is compressed, and the relative position between the inner and outer positioning frames changes until the spring can no longer be compressed, thus completing the clamping of the skeleton side plate. During the part docking stage, when the skeleton side plate contacts the crossbeam, the airbag can adjust the lateral position of the skeleton side plate by deformation. At the same time, the spring pushes outward, and the inner positioning frame provides a stable clamping function. This not only adjusts the displacement and stress generated during part docking but also ensures the stable support required for welding. Attached Figure Description

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1 to 3 As shown, this embodiment proposes an automatic calibration welding device for automotive seat frames, including a welding robot 1 and a base frame 2. A support bracket 3 is rotatably mounted on the base frame 2, and a load-bearing bracket 4 is fixedly mounted on the support bracket 3. The welding robot 1 is located on the side of the base frame 2. The device also includes sliding frames 5, sliding tables 7, clamping and adjusting components, flexible clamping components, and crossbeam clamping components. Two sliding frames 5 are symmetrically and slidably mounted on the load-bearing bracket 4, and a clamping frame 6 is slidably mounted on the sliding frames 5. Two sliding tables 7 are symmetrically and slidably mounted on the load-bearing bracket 4, and sliding tables 7 are slidably mounted on the sliding tables 7. There is a sliding bracket 8, which can only move longitudinally along the slide table 7, and the sliding frame 5 can only move laterally. The bearing bracket 4 is equipped with a clamping and adjusting component, which is used to adjust the position between the frame side plates that constitute the car seat frame when clamping them. In order to adjust the position of the seat frame during welding, a drive motor 9 is fixedly installed inside the base frame 2. Two meshing transmission gears 10 are rotatably installed inside the base frame 2. The output end of the drive motor 9 is fixedly connected to one of the transmission gears 10, and the other transmission gear 10 is fixedly connected to the support bracket 3.

[0048] When welding the car seat frame, the two frame side plates are first placed on the two clamping frames 6 respectively and clamped by the flexible clamping components. Then, the lateral distance between the two sliding frames 5 is adjusted by the clamping adjustment components so that the two frame side plates reach the relative positions required by the drawings. Then, the crossbeam is placed on the crossbeam clamping components, and the height and longitudinal position of the crossbeam are adjusted by the lifting knob 305 and the sliding bracket 8 so that its two ends are aligned with the frame side plates on both sides. After the alignment is completed, the welding robot 1 can be started to begin welding.

[0049] During the welding process, in order to adjust the welding position, the drive motor 9 can be turned on to drive the support bracket 3 and the load-bearing bracket 4 to rotate as a whole through the transmission gear 10, thereby flipping the seat frame to the optimal angle suitable for the operation of the welding robot 1.

[0050] The clamping and adjusting assembly includes a bidirectional screw 101 and a first motor 103, such as Figures 4 to 6 As shown, a bidirectional screw 101 is rotatably mounted inside the bearing bracket 4. Two movable nuts 102 are symmetrically threaded onto the bidirectional screw 101. The two movable nuts 102 are fixedly connected to two sliding frames 5 respectively. A first motor 103 is fixedly mounted inside the bearing bracket 4. The output end of the first motor 103 is fixedly connected to the bidirectional screw 101. The system also includes an adjusting screw 104 and an adjusting knob 106. An adjusting screw 104 is rotatably mounted inside each of the two sliding frames 5. An adjusting nut 105 is threaded onto the adjusting screw 104. The adjusting nut 105 is fixedly connected to the clamping frame 6. An adjusting knob 106 is rotatably mounted on each of the two sliding frames 5. The adjusting knob 106 is fixedly connected to the adjusting screw 104.

[0051] When it is necessary to adjust the distance between the two frame side plates, the first motor 103 can be started. The first motor 103 drives the bidirectional screw 101 to rotate. The bidirectional screw 101 drives the two moving nuts 102 to move synchronously in opposite directions. The two moving nuts 102 are fixedly connected to the two sliding frames 5 respectively. Therefore, the two sliding frames 5 will move in opposite directions at the same time, thereby accurately adjusting the relative position of the two frame side plates.

[0052] When it is necessary to fine-tune the longitudinal position of the single-sided clamping frame 6, the adjustment knob 106 can be grasped and rotated. The adjustment knob 106 drives the adjustment screw 104 to rotate, and the adjustment screw 104 drives the adjustment nut 105 to move, thereby driving the clamping frame 6 to slide longitudinally along the sliding frame 5, so as to independently adjust the longitudinal position of the skeleton side plate, and then control the relative position of the two skeleton side plates step by step and precisely, so as to facilitate the alignment of the two skeleton side plates.

[0053] The clamping frame 6 is equipped with a flexible clamping assembly for flexibly clamping the side plates of the skeleton and accommodating displacement of the docking position when the parts to be welded are joined together. The flexible clamping assembly includes a first driving component 201, an outer positioning frame 203, and an inner positioning frame 204. Figures 6 to 8 As shown, a first driving component 201 is installed on each of the two clamping frames 6. A pulling frame 202 is fixedly installed at the output end of the first driving component 201. The pulling frame 202 is slidably engaged with the clamping frame 6. An outer positioning frame 203 is fixedly installed on each pulling frame 202. An inner positioning frame 204 is slidably installed inside each outer positioning frame 203. A spring 205 is fixedly installed between the inner positioning frame 204 and the outer positioning frame 203. An abutment frame 206 is slidably installed inside each clamping frame 6. The abutment frame 206 corresponds to the position of the inner positioning frame 204. An airbag 207 is installed inside the clamping frame 6. The other end of the airbag 207 abuts against the side of the abutment frame 206 away from the inner positioning frame 204.

[0054] Before clamping, turn on the air supply device to inflate the airbag 207. When the airbag 207 expands, it can push the abutment frame 206 outward to the designated position. When it is necessary to clamp the skeleton side plate, first put the skeleton side plate on the clamping frame 6, and then turn on the first drive component 201. The first drive component 201 pulls the pull frame 202 to move. The pull frame 202 drives the outer positioning frame 203 and the inner positioning frame 204 to move together toward the skeleton side plate until the inner positioning frame 204 contacts the skeleton side plate. Then the skeleton side plate can be pushed to move until the skeleton side plate contacts the abutment frame 206. At the same time, the spring 205 is compressed, and the relative position between the inner positioning frame 204 and the outer positioning frame 203 changes until the spring 205 can no longer be compressed. The entire inner positioning frame 204 becomes a rigid support, and the clamping is completed.

[0055] During the part assembly stage, when the frame side plate contacts the crossbeam, the airbag 207 can adjust the lateral position of the frame side plate by deforming, that is, move the frame side plate away from the inner positioning frame 204. At the same time, the spring 205 pushes outward, and the inner positioning frame 204 plays a stable clamping role. It can not only adjust the displacement and stress generated during part assembly, but also ensure the stable support required for welding during the welding process.

[0056] The sliding bracket 8 is equipped with a crossbeam clamping assembly for clamping the crossbeams that form the car seat frame. The crossbeam clamping assembly includes an outer bracket 301, an inner bracket 302, and a lifting knob 305. Figure 9As shown, each sliding bracket 8 is equipped with an inner sleeve 302, and each inner sleeve 302 is slidably equipped with an outer sleeve 301. Each outer sleeve 301 has a lifting screw 303 rotatably mounted on its inner bottom wall, and each lifting screw 303 has a lifting nut 304 threaded onto it. The lifting nut 304 is fixedly connected to the inner sleeve 302. Each outer sleeve 301 has a lifting knob 305 rotatably mounted on it, and the lifting knob 305 is fixedly connected to the lifting screw 303. The sliding bracket 8 is provided with a fastening screw 306 to determine the relative position between the sliding bracket 8 and the slide table 7. It also includes a mounting bracket 307. Each outer sleeve 301 is equipped with a mounting bracket 307. Two second driving members 308 are symmetrically and fixedly mounted on the mounting bracket 307. The output end of the second driving member 308 is fixedly provided with a positioning pad 309 for abutting against the crossbeam. An anti-slip pad 310 is also installed inside the mounting bracket 307.

[0057] Before placing the crossbeam, the height and longitudinal position of the crossbeam need to be adjusted according to the actual situation. At this time, rotate the lifting knob 305, which drives the lifting screw 303 to rotate. The lifting screw 303 drives the lifting nut 304, which in turn drives the inner sleeve 302 to move up and down along the outer sleeve 301, thereby adjusting the height of the mounting bracket 307.

[0058] The entire sliding bracket 8 can be manually pushed to slide longitudinally on the slide table 7. After the crossbeam is adjusted to the appropriate position, the fastening screw 306 can be tightened to lock the sliding bracket 8 in the current position. When the crossbeam is placed on the mounting bracket 307, the corresponding second drive component 308 is activated. The second drive component 308 pushes the positioning pad 309 to move, thereby fixing the position of the crossbeam under the action of the anti-slip pad 310. The anti-slip pad 310 increases the friction between the crossbeam and the mounting bracket 307 to prevent the crossbeam from rotating or moving axially during the welding process.

[0059] When welding the car seat frame is required, the air supply device is turned on to inflate the airbag 207 before clamping the seat frame parts. At this time, the airbag 207 expands and pushes the abutment frame 206 outward to the designated position. When clamping the frame side plate is required, the frame side plate is first placed on the clamping frame 6, and then the first drive component 201 is turned on. The first drive component 201 pulls the pull frame 202 to move. The pull frame 202 drives the outer positioning frame 203 and the inner positioning frame 204 to move together towards the frame side plate until the inner positioning frame 204 contacts the frame side plate, and then pushes the frame side plate to move until the frame side plate contacts the abutment frame 206. At the same time, the spring 205 is compressed, and the relative position between the inner positioning frame 204 and the outer positioning frame 203 changes until the spring 205 can no longer be compressed. The entire inner positioning frame 204 becomes a rigid support, which completes the clamping of the frame side plate.

[0060] Next, the position of the crossbeam needs to be fixed. After placing the crossbeam on the mounting bracket 307, the corresponding second drive component 308 is activated. The second drive component 308 pushes the positioning pad 309 to move, thereby fixing the position of the crossbeam under the action of the anti-slip pad 310. The anti-slip pad 310 increases the friction between the crossbeam and the mounting bracket 307, preventing the crossbeam from rotating or moving axially during the welding process. Before installing the crossbeam, the lifting knob 305 needs to be rotated. The lifting knob 305 drives the lifting screw 303 to rotate, and the lifting screw 303 drives the lifting nut 304, thereby driving the inner sleeve 302 to move up and down along the outer sleeve 301, thereby adjusting the height of the mounting bracket 307. When adjusting the longitudinal position of the sliding bracket, the entire sliding bracket 8 is pushed to slide on the slide table 7. After the crossbeam is adjusted to the appropriate position, the fastening screw 306 can be tightened to lock the sliding bracket 8 in the current position.

[0061] When it is necessary to adjust the longitudinal position of the single-sided clamping frame 6, first grasp and rotate the adjustment knob 106. The adjustment knob 106 drives the adjustment screw 104 to rotate, and the adjustment screw 104 drives the adjustment nut 105 to move, thereby driving the clamping frame 6 to slide longitudinally along the sliding frame 5, so as to independently adjust the longitudinal position of the skeleton side plate, and then control the relative position of the two skeleton side plates step by step and precisely, so as to facilitate the alignment of the two skeleton side plates.

[0062] When it is necessary to align the welding positions of the frame side plates with the welding positions of the crossbeam, the first motor 103 is started first. The first motor 103 drives the bidirectional screw 101 to rotate, and the bidirectional screw 101 drives the two moving nuts 102 to move synchronously in opposite directions. The two moving nuts 102 are fixedly connected to the two sliding frames 5 respectively. Therefore, the two sliding frames 5 will move in opposite directions at the same time, thereby accurately adjusting the relative positions of the two frame side plates. During the part docking stage, when the frame side plate contacts the crossbeam, the airbag 207 can adjust the lateral position of the frame side plate by deformation. At the same time, the spring 205 pushes outward, and the inner positioning frame 204 plays a stable clamping role. It can not only adjust the displacement and stress generated during part docking, but also ensure the stable support required for welding during the welding process.

[0063] Once the docking is complete, welding robot 1 can be started to begin welding. During the welding process, in order to adjust the welding position, drive motor 9 can be turned on to drive support bracket 3 and load-bearing bracket 4 to rotate as a whole through transmission gear 10, thereby flipping the seat frame to the optimal angle suitable for welding robot 1 to operate.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
