[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] Embodiment 1, as Figure 1 And Figure 2 shown, a processing device for an automobile seat bracket includes a processing table 1, a rotating component 4 is rotatably connected to the front side of the upper end of the processing table 1, clamping components 2 are fixedly connected to the front side and the rear side of the rotating component 4, pushing components 5 are symmetrically arranged on the upper end of the processing table 1, a welding manipulator 3 is fixedly connected to the rear side of the upper end of the processing table 1, a grinding component 6 is fixedly connected to the upper end of the processing table 1 above the welding manipulator 3, and blowing and suction components 7 are symmetrically arranged on the upper end of the processing table 1 on the side where the two pushing components 5 are close to each other.

[0033] During the processing and production of an automobile seat bracket, especially when processing the seat base skeleton, the two cross beams to be welded are respectively placed and fixed by using the clamping component 2, and then the clamping component 2 fixing the cross beam is rotated to the rear side by cooperating with the rotating component 4. Then, the cross beam to be welded can be fixed again by using the clamping component 2. After the clamping component 2 drives the cross beam to be rotated to the rear side by cooperating with the rotating component 4, the two side plates are pushed towards the middle by cooperating with the two pushing components 5, and the welding of the two side plates and the cross beam is prepared to form the skeleton of the seat base;

[0034] While the two pushing components 5 are pushing the side plates to move, the two blowing and sucking components 7 cooperate to continuously blow air at both ends of the two cross beams, preventing small particles such as dust on the cross beams from affecting the subsequent welding quality. After the welding is completed by the cooperation of the welding robot arm 3, the grinding component 6 pre-treats and grinds the weld seam. When preparing for the pre-treatment grinding, the grinding component 6 cooperates to release the locking of the two pushing components 5 on the side plates, and then the two pushing components 5 reset. During the process of the grinding component 6 grinding the weld seam, the two blowing and sucking components 7 cooperate to suck air around the weld seam, guiding the air flow around the weld seam and collecting the slag ground out at the same time, which is convenient for directly inspecting the welding quality.

[0035] The above-mentioned welding robot arm 3 is a conventional design in the prior art. The welding robot arm 3 is electrically connected to the control terminal system in the prior art. Before welding the frame of the seat base, the welding path and related parameters are input into the control terminal system. After starting, the control terminal system drives the motors of the joints of the robot arm to move, and moves the laser welding head to the position to be welded according to the predetermined trajectory.

[0036] During the operation of this embodiment, through the cooperation of the rotating component 4 and the two clamping components 2, the cross beam to be welded can be conveniently fixed and turned, facilitating the operation of multiple workstations at the same position. At the same time, through the operation of the grinding component 6, the weld seam is pre-treated and ground after welding, which helps to remove burrs, spatter, etc. on the surface of the weld seam, making the surface of the weld seam smoother and providing a good foundation for subsequent quality inspection and surface treatment. Through the cooperation of the pushing component 5 and the blowing and sucking component 7, air is blown at both ends of the cross beam before welding, which can remove small particles such as dust and prevent them from affecting the welding quality; during the grinding process after welding, air can be sucked around the weld seam, guiding the air flow and collecting the slag, which not only helps to detect welding defects in time, but also keeps the working environment clean and further improves the welding quality.

[0037] Embodiment 2. On the basis of Embodiment 1, in order to achieve the effect of blowing and cleaning the welded part before welding, collecting the slag after welding, and at the same time being able to finely adjust the angle of the side plate to ensure the welding accuracy.

[0038] Refer to Figure 3 , the rotating component 4 includes a rotating shaft 42 rotatably connected to the upper end of the processing table 1, and a T-shaped plate 41 is fixedly connected to the upper part of the outer surface of the rotating shaft 42.

[0039] The above-mentioned rotating shaft 42 is electrically connected to the control terminal system in the prior art and is simultaneously fixedly connected to the rotation power source. Through the presetting of the control terminal system, the rotating shaft 42 can drive the T-shaped plate 41 to rotate 180° each time.

[0040] Meanwhile, through the cooperation of the T-shaped plate 41, the smoke and spatter generated during the operation of the welding robot arm 3 are prevented from spreading everywhere. Further, through the cooperation of the T-shaped plate 41, the flow of external gas into the welding area is reduced, which helps to reduce the generation of welding defects caused by the influence of air flow.

[0041] Refer to Figures 3 - 5 , the clamping assembly 2 includes a support plate 21 fixedly connected to the front end of the horizontal part of the T-shaped plate 41. On the upper left side of the support plate 21, a first guide rail 211 is fixedly connected. On the upper right side of the support plate 21, a second guide rail 212 is fixedly connected. On the upper end of the support plate 21, gears 23 are symmetrically rotatably connected. On the outer surface of the first guide rail 211, first racks 24 are symmetrically slidably connected. On the upper ends of the two first racks 24, first clamping blocks 25 are rotatably connected. On the outer surface of the second guide rail 212, second racks 26 are symmetrically slidably connected. On the upper ends of the two second racks 26, second clamping blocks 27 are rotatably connected. The mutually approaching ends of the two second racks 26 are commonly fixedly connected with a fixing rod 28. At the lower end of the support plate 21, a first hydraulic cylinder 22 is fixedly connected. The output end of the first hydraulic cylinder 22 is fixedly connected with an L-shaped rod 221. The left end of the horizontal part of the L-shaped rod 221 is fixedly connected with the fixing rod 28.

[0042] Before preparing to weld the cross beam and the side plate, the two cross beams are sequentially placed on the front side and the rear side of the upper end of the support plate 21, and then the first hydraulic cylinder 22 is activated. At this time, the output end of the first hydraulic cylinder 22 pushes the L-shaped rod 221 backward, and then drives the fixing rod 28 to move backward simultaneously;

[0043] Refer to Figure 4 , during the backward movement of the fixing rod 28, the two second racks 26 are driven to move backward simultaneously along the outer surface of the second guide rail 212. Then, through the common cooperation with the adapted gears 23, the two first racks 24 move forward simultaneously along the first guide rail 211. During the movement of the second racks 26, the second clamping blocks 27 are driven to move in the same direction. Similarly, the first clamping blocks 25 are driven by the first racks 24 to move in the same direction. Then, through the common cooperation of the first clamping blocks 25 and the second clamping blocks 27 on the same side, the rapid and precise clamping of the two cross beams is realized.

[0044] Similarly, according to the width of the two cross beams, the distance between the second clamping blocks 27 and the first clamping blocks 25 on the same side is appropriately adjusted, so that the first clamping blocks 25 and the second clamping blocks 27 on the front side and the rear side cooperate to realize the common clamping and fixing of the two cross beams.

[0045] Refer to Figure 4 , on the upper end of the support plate 21 on the right side of the second guide rail 212, a rectangular hole 213 is opened. The outer surface of the vertical part of the L-shaped rod 221 is slidably connected with the inner surface of the rectangular hole 213. A plurality of limiting grooves 214 are opened on the front sides of the left end and the right end of the support plate 21.

[0046] During the process of the output end of the hydraulic cylinder 22 pushing the L-shaped rod 221 forward, the L-shaped rod 221 slides backward along the inner surface of the rectangular hole 213. During the sliding process of the L-shaped rod 221, it will drive the fixed rod 28 to move in the same direction, and then the fixed rod 28 drives the two racks 26 to move simultaneously.

[0047] After fixing two crossbeams above the support plate 21 fixed to the front end of the horizontal part of the T-shaped plate 41, through the control terminal system in the prior art, control the rotating shaft 42 to drive the T-shaped plate 41 and the support plate 21 to rotate 180° simultaneously. Then, two crossbeams can be placed above the support plate 21 that can be rotated to the front side to prepare for the next set of welding.

[0048] The two crossbeams rotated to the rear side are ready for welding.

[0049] Furthermore, the crossbeam placement and welding work are alternately carried out on the front side and the rear side, improving the work efficiency and realizing the continuous preparation of multiple sets of welding.

[0050] Refer to Figures 6 - 8 , the pushing component 5 includes a motor 51 fixedly connected to the upper end of the processing table 1. The output end of the motor 51 is fixedly connected with a bidirectional lead screw 511. A push plate 52 is arranged on the outer surface of the bidirectional lead screw 511. The upper end of the push plate 52 is rotatably connected with a cross plate 53. The upper end of the cross plate 53 is fixedly connected with an L-shaped magnetic suction seat 54. The right end of the L-shaped magnetic suction seat 54 is electrically connected with a control key 55. A limiting roller 56 is fixedly connected to the upper end of the processing table 1. The outer surface of the limiting roller 56 is slidably connected with the push plate 52.

[0051] The above-mentioned L-shaped magnetic suction seat 54 is a conventional design in the prior art. A segmented coil is arranged inside the L-shaped magnetic suction seat 54 to offset the magnetic field distortion at the corner. At the same time, the main body uses high-permeability silicon steel sheets to reduce the magnetic resistance and enhance the adsorption force. By electrically connecting the control key 55 with the coil inside the L-shaped magnetic suction seat 54, the on-off of the current inside the coil can be controlled. When there is current passing through the coil inside the L-shaped magnetic suction seat 54, magnetic suction force will be generated to adsorb and fix the side plate. When there is no current in the coil inside the L-shaped magnetic suction seat 54, the magnetic suction force disappears. At this time, the L-shaped magnetic suction seat 54 has no adsorption effect on the side plate and can only simply support the side plate.

[0052] After the support plate 21 drives the two crossbeams to turn to the rear side, through the feeding device in the prior art, place the side plate on the upper end of the L-shaped magnetic suction seat 54. Then, connect the circuit. There is current flowing through the coil inside the L-shaped magnetic suction seat 54. At this time, the L-shaped magnetic suction seat 54 adsorbs and fixes the side plate through the magnetic suction force.

[0053] Then, start the motor 51. The output end of the motor 51 drives the bidirectional lead screw 511 to rotate. Through the cooperation of the limiting roller 56, the push plate 52 moves along the bidirectional lead screw 511 toward the side close to the support plate 21. Then, the push plate 52 drives the cross plate 53 and the L-shaped magnetic suction seat 54 to move in the same direction.

[0054] Refer to Figure 7 , at the left end of the cross plate 53, a plurality of springs 532 are fixedly connected, and at the left ends of the plurality of springs 532, bumps 531 are fixedly connected. The outer surfaces of the plurality of bumps 531 are respectively in close contact with the inner surfaces of the adapted limiting grooves 214.

[0055] Refer to Figure 5 and Figure 7 , when the push plate 52 drives the cross plate 53 and the L-shaped magnetic suction seat 54 to move close to the support plate 21, at this time, the outer surface of the bump 531 begins to contact the inner surface of the adapted limiting groove 214. As the push plate 52 drives the cross plate 53 to continue to move forward, the bump 531 moves into the interior of the limiting groove 214. Through the mutual cooperation of the bump 531 and the limiting groove 214, the angle of the cross plate 53 is finely adjusted so that the left end of the cross plate 53 is parallel to the right end of the support plate 21. Furthermore, the L-shaped magnetic suction seat 54 can drive the side plate to finely adjust the angle, ensuring that the side plate is in close contact with and perpendicular to the two cross beams, and ensuring the welding accuracy.

[0056] Furthermore, the welding robot arm 3 can be activated to sequentially weld the positions where the two cross beams and the side plate are in close contact.

[0057] Refer to Figures 10 - 11 , the blowing and sucking assembly 7 includes a vertical plate 72 fixedly connected to the upper end of the processing table 1. The vertical plate 72 and the push plate 52 on the same side are jointly fixedly connected with an air bag 71. The upper end of the vertical plate 72 is fixedly connected with a spray pipe 73. A plurality of nozzles 731 are fixedly connected to the outer surface of the spray pipe 73. The left end of the vertical plate 72 is fixedly connected with a collection box 74. A plurality of filter holes 741 are formed in the right side wall of the inner surface of the collection box 74. The air bag 71 is communicated with the inner surface of the spray pipe 73.

[0058] The air bag 71 mentioned above is made of silicone rubber commonly used in the prior art, which can not only make the whole air bag 71 resistant to high temperature but also have excellent elasticity, and can meet large stretching while also being able to be compressed less.

[0059] During the process of the push plate 52 driving the cross plate 53, the L-shaped magnetic suction seat 54 and the side plate to approach the cross beam and prepare to move, the push plate 52 will simultaneously push the right end of the air bag 71. Through the cooperation with the vertical plate 72, the air bag 71 is compressed. During the compression of the air bag 71, the gas inside the air bag 71 enters the interior of the spray pipe 73 through the channel communicated with the spray pipe 73 and is ejected from a plurality of nozzles 731. Thus, it can blow air obliquely upward from the lower directions at both ends of the cross beam to blow away dust and other fine particles at both ends of the cross beam, avoiding the influence of fine particles on the subsequent welding quality.

[0060] During the process of a plurality of nozzles 731 ejecting gas outward, through the cooperation of a plurality of filter holes 741, the ejected gas blows more evenly towards both ends of the cross beam.

[0061] Refer toFigure 9 , the grinding assembly 6 includes a second hydraulic cylinder 61 fixedly connected to the upper end of the processing table 1. The output end of the second hydraulic cylinder 61 is fixedly connected with a fixing plate 62. The lower end of the fixing plate 62 is fixedly connected with a grinding robotic arm 63. Both the left end and the right end of the fixing plate 62 are fixedly connected with a lever 64. The upper end of the fixing plate 62 is slidably connected to the processing table 1. When the output end of the second hydraulic cylinder 61 pushes the fixing plate 62 to move, the two levers 64 respectively contact the adapted control keys 55.

[0062] The above-mentioned grinding robotic arm 63 is a conventional design in the prior art. The grinding robotic arm 63 is electrically connected to the control terminal system in the prior art, and inputs relevant parameters and instructions for the grinding task of the grinding robotic arm 63, including model data of the workpiece, grinding path planning, grinding process parameters such as grinding speed, strength, and number of times, etc. During the operation of the grinding robotic arm 63, the grinding tool is driven to rotate at a high speed, contact the surface of the welded part and perform grinding.

[0063] After the welding robotic arm 3 welds the positions where the two crossbeams and the two side plates are in contact respectively, stop the operation of the welding robotic arm 3. At this time, the welding head of the welding robotic arm 3 resets, and then activate the second hydraulic cylinder 61, so that the output end of the second hydraulic cylinder 61 pushes the fixing plate 62 forward. Then the fixing plate 62 drives the grinding robotic arm 63 to move above the welded seat frame, and then the grinding robotic arm 63 can be activated to achieve the preliminary grinding of the weld.

[0064] When the fixing plate 62 drives the grinding robotic arm 63 to move forward to prepare for grinding, the fixing plate 62 drives the two levers 64 to move forward at the same time. Then, during the forward movement of the two levers 64, they will contact and squeeze the lower part of the outer surface of the control key 55, realizing a single press on the control key 55. After the lever 64 leaves the outer surface of the control key 55, the control key 55 resets immediately. Then, after the control key 55 is pressed once, the control key 55 disconnects the current in the coil inside the L-shaped magnetic seat 54, so that there is no current in the coil inside the L-shaped magnetic seat 54 anymore. Then the L-shaped magnetic seat 54 no longer has magnetic attraction. At this time, the L-shaped magnetic seat 54 no longer has an adsorption and fixing effect on the side plate, and only the upper end of the horizontal part of the L-shaped magnetic seat 54 simply supports the side plate. Then, through the cooperation of the motor 51 and the bidirectional lead screw 511, the push plate 52 drives the cross plate 53 and the L-shaped magnetic seat 54 to reset, preparing for the feeding of a new side plate.

[0065] During the reset process of the push plate 52, it drives the right end of the airbag 71 to move in the same direction. Then the airbag 71 will be stretched. At this time, the air pressure inside the airbag 71 decreases, and then the airbag 71 continuously inhales air, and the gas around the weld between the crossbeam and the side plate is driven to flow into the airbag 71 through a number of nozzles 731.

[0066] Subsequently, during the process of the grinding robotic arm 63 grinding the weld seam, the gas around the weld seam drives the welding slag ground up to flow towards the collection box 74. Through the cooperation of a number of filter holes 741, the welding slag is blocked on the side wall of the inner surface of the filter holes 741, and the gas is sucked into the interior of the airbag 71.

[0067] After the push plate 52 is reset, at this time, the grinding robotic arm 63 also finishes the pre-treatment grinding of all weld seams, which is convenient for visually inspecting the welding quality of the seat base skeleton. Then, the output end of the second hydraulic cylinder 61 drives the fixed plate 62, the grinding robotic arm 63 and the two lever rods 64 to reset.

[0068] During the reset process of the two lever rods 64, the lever rods 64 will squeeze the control key 55 again. Through the cooperation of the control key 55, an electric current is passed through the coil inside the L-shaped magnetic suction seat 54, that is, the L-shaped magnetic suction seat 54 is made to have magnetic suction again, and it can adsorb and fix the side plate to prepare for the next welding.

[0069] The base skeleton after welding the two cross beams and the side plate is rotated forward through the cooperation of the support plate 21, the T-shaped plate 41 and the rotating shaft 42. During the rotation process, the welding slag blocked by the filter holes 741 will automatically fall onto the bottom wall of the inner surface of the filter holes 741 due to its own gravity. When the subsequent airbag 71 is compressed, the gas blown out by a number of nozzles 731 will not blow out the welding slag.

[0070] For the welded base skeleton, the first hydraulic cylinder 22 can cooperate with the L-shaped rod 221 and the fixed rod 28 to move the second clamping block 27 forward and the first clamping block 25 backward, releasing the fixation of the first clamping block 25 and the second clamping block 27 on the welded base skeleton. Then, the material can be unloaded, and a new cross beam can be placed above the support plate 21 again and fixed to prepare for the next welding.

[0071] Therefore, through the cooperation of structures such as the first clamping block 25 and the second clamping block 27, the precise clamping and fixation of the cross beam are realized. Through the cooperation of the push plate 52, the airbag 71, the spray pipe 73 and the collection box 74, not only can the cross beam be blown with air to achieve the effect of cleaning dust and small particles when preparing for welding, but also can inhale air when pre-treating and grinding the weld seam after welding to achieve the purpose of collecting and cleaning the welding slag. At the same time, through the cooperation of the convex block 531 and the limiting groove 214, the angle of the side plate can be finely adjusted during the process of moving the side plate to prepare for welding, ensuring that the side plate and the cross beam are precisely perpendicular and improving the welding quality.

[0072] It should be particularly noted that the specific installation methods of the first hydraulic cylinder 22, the motor 51 and the second hydraulic cylinder 61 adopted in the present invention, the connection method of the circuit and the control method all belong to conventional designs, and the present invention will not elaborate in detail.

[0073] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
