[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 10 As shown, this embodiment proposes a welding tool for automobile seat accessories, including a device frame 1, two sliding frames 2 are symmetrically and slidingly installed on the device frame 1, an assembly frame 3 is fixedly installed on the upper part of the device frame 1, the assembly frame 3 is located between the two sliding frames 2, and also includes a welding fixture 4, an adjustment frame 5, a clamping component, a support component and an adjustment component, a plurality of welding fixtures 4 are arranged on the top of the assembly frame 3, the two sliding frames 2 are fixedly installed with an adjustment frame 5, the two adjustment frames 5 are installed with a clamping component for clamping automobile seat accessories, the clamping component includes a sliding frame 6, a mobile frame 7, a clamping frame 8 and a clamping part, the two adjustment frames 5 are slidably installed with a sliding frame 6, the two sliding frames 6 are slidably installed with a mobile frame 7, the two mobile frames 7 are fixedly installed with a clamping frame 8, the clamping frame 8 close to the side of the adjustment frame 5 does not contact the adjustment frame 5, and each clamping frame 8 is installed with a clamping part for fixing the automobile seat accessories to be welded.

[0022] Among them, when welding the seat cushion frame in the automobile seat accessories "the seat cushion frame is mainly composed of side panels 29 and cross beams 30 (the cross beams 30 mainly include front beams and rear beams)", during the welding process, the side panels 29 and cross beams 30 that constitute the seat cushion frame need to be fixed.

[0023] Specifically, when welding the cushion framework in the automobile seat accessory, the corresponding automobile accessory needs to be clamped first. At this time, the two side plates 29 are clamped on the clamping part respectively. Then, the position of the sliding frame 6 is adjusted through the setting of the positioning assembly, so that the position of the clamping frame 8 is adjusted through the setting of the moving frame 7, so that the lateral position of the side plate 29 is adjusted, and the vertical position of the side plate 29 is adjusted through the setting of the clamping part. Until the two side plates 29 are symmetrically arranged, then according to the model of the cushion framework, the installation position of the cross beam 30 is determined. Generally, two cross beams 30 are provided, that is, installed at the front end and the rear end between the two side plates 29 (part of the cushion framework will also be provided with a cross beam 30 in the middle of the two side plates 29). Then, the corresponding welding fixture 4 is installed at the corresponding position on the assembly frame 3, and the corresponding cross beam 30 is installed on the welding fixture 4. At this time, the welding positions of the two ends of the cross beam 30 correspond to the welding positions of the side plates 29, and the distances between the two ends of the cross beam 30 and the corresponding side plates 29 are the same. At this time, the positioning assembly is turned on, and the two sliding frames 2 are reversely moved synchronously, so as to drive the corresponding positioning frame 5 to move, so that the clamped side plate 29 is moved through the setting of the clamping frame 8. Until the side plate 29 abuts against the end of the cross beam 30, and is tightly abutted under the action of the supporting assembly, the positioning assembly can be closed, the welding equipment is turned on, and the side plate 29 and the cross beam 30 are welded.

[0024] It should be noted that the cushion framework is mainly composed of a main frame, a T-shaped frame, a horizontal support and an L-shaped connecting piece, etc. The main frame is generally formed by stamping a thin steel plate, and then welded into an integral support structure, that is, the side plate 29 and the cross beam 30 are combined and welded. According to the ergonomic principle, the curved radius is designed to ensure uniform support for the hips and legs. Other components, such as the T-shaped frame and the horizontal support, are generally fixed to the vehicle body sheet metal through connecting pieces. The L-shaped structure connecting piece penetrates the support body, one end is welded with the T-shaped frame, and the other end is bolted with the vehicle body sheet metal, which is used for rigid fixation of the framework and the vehicle chassis, etc.

[0025] As described above, Figure 5 , Figure 7As shown, the clamping part includes a lifting clamping frame 9, a first driving member 10, a positioning clamping frame 13 and a second driving member 14. The lifting clamping frame 9 is slidably installed on the two clamping frames 8. Each lifting clamping frame 9 is provided with a positioning protrusion 12 on the side close to the clamping frame 8. The first driving member 10 is fixedly installed on the two clamping frames 8. The output end of the first driving member 10 is fixedly installed with a push plate 11, which is located inside the clamping frame 8. The push plate 11 slides with the clamping frame 8, wherein the push plate 11 is fixedly connected to the lifting clamping frame 9. Two positioning clamping frames 13 are slidably and symmetrically installed on the two lifting clamping frames 9. Two second driving members 14 are fixedly and symmetrically installed on the two lifting clamping frames 9, and the output end of the second driving member 14 is fixedly connected to the positioning clamping frame 13.

[0026] Specifically, when clamping the side panel 29, first place the side panel 29 on the corresponding lifting clamping frame 9. At this time, the bottom of the side panel 29 contacts the lifting clamping frame 9, and the side of the side panel 29 close to the positioning protrusion 12 contacts the positioning protrusion 12. At this time, the position of the side panel 29 can be fixed. At this time, the corresponding second driving member 14 is turned on, thereby driving the corresponding positioning clamping frame 13 to move until the positioning clamping frame 13 contacts the side panel 29. The side panel 29 can be clamped by cooperating with the positioning clamping frame 13 and the positioning protrusion 12. After clamping the side panel 29, the first driving member 10 is turned on. The first driving member 10 pushes the lifting clamping frame 9 to move in the vertical direction through the pushing plate 11, thereby adjusting the height of the side panel 29 to facilitate docking with other accessories such as other beams 30.

[0027] It should be added that in order to improve the clamping stability of the side plate 29, the positioning protrusion 12 and the part where the positioning clamping frame 13 contacts the side plate 29 are provided with rubber pads. The rubber pads can also be provided with anti-slip grooves for increasing friction. In the process of clamping the side plate 29, the rubber pads play a role in increasing the clamping stability. During the welding process, due to the effect of heat, the metal material will expand and contract, resulting in changes in the size of the workpiece. At this time, the deformation of the rubber pads can be used to adapt to this change without affecting the stability of the clamping.

[0028] like Figures 8 to 10 As shown, a supporting assembly is installed inside each clamping assembly to support the position of the clamping assembly. The supporting assembly includes a first positioning block 15, a second positioning block 16, a third driving member 17 and a spring 18. The first positioning block 15 is fixedly installed inside the two mobile frames 7, and the second positioning block 16 is slidably installed inside the two sliding frames 6. The second positioning block 16 is located on the upper part of the first positioning block 15. The third driving member 17 is fixedly installed on the top of the two sliding frames 6. The output end of the third driving member 17 is fixedly connected to the second positioning block 16. A spring 18 is fixedly installed between the two mobile frames 7 and the two sliding frames 6.

[0029] When the side plates 29 and the cross beam 30 are in contact with each other, the movable frame 7 and the sliding frame 6 move relative to each other. At this time, the spring 18 is compressed, and the elastic force of the spring 18 provides a certain pressure on the side plates 29 and the cross beam 30, so as to tighten the welding position of the cross beam 30 and the side plates 29. Then, the relative position between the movable frame 7 and the sliding frame 6 needs to be fixed. At this time, the third driving member 17 is opened, and the third driving member 17 pushes the second positioning block 16 to move until the second positioning block 16 is tightly abutted against the first positioning block 15. The third driving member 17 can be closed, and the position between the movable frame 7 and the sliding frame 6 can be fixed.

[0030] like Figures 4 to 6 As shown, a positioning assembly is installed in the device frame 1 for synchronously adjusting the relative positions of the two sliding frames 2. The positioning assembly includes a bidirectional screw 19, an adjusting nut 20, a transverse positioning portion and a positioning portion. A bidirectional screw 19 is rotatably installed inside the device frame 1. Two adjusting nuts 20 are symmetrically and threadedly mounted on the bidirectional screw 19. The two adjusting nuts 20 are respectively fixedly connected to the two sliding frames 2. A transverse positioning portion is installed inside the two positioning frames 5 for adjusting the relative position between the sliding frame 6 and the positioning frame 5. A positioning portion is installed on the device frame 1 and the two positioning frames 5 for fixing the transverse positioning portion and the rotational position of the bidirectional screw 19.

[0031] Among them, a hand wheel 28 is rotatably mounted on the device frame 1 , and the hand wheel 28 is coaxial with and fixedly connected to the bidirectional screw 19 .

[0032] Specifically, when adjusting the relative position of the two sliding frames 2, the handwheel 28 is turned to drive the bidirectional screw 19 to rotate, thereby driving the two adjusting nuts 20 to move in the opposite direction, thereby driving the corresponding sliding frame 2 to move, and the position of the side plate 29 can be adjusted. By setting the transverse adjustment part, the transverse position of the side plate 29 can be adjusted to facilitate alignment of the welding position of the side plate 29 and the crossbeam 30. After the welding positions of the side plate 29 and the crossbeam 30 are docked together, in order to avoid dislocation during the welding process, the positioning part is opened to lock the bidirectional screw 19 and the adjusting screw 21, thereby improving the stability during the welding process.

[0033] The above, such as Figure 5As shown, the transverse position adjusting part comprises adjusting screw rods 21, the adjusting screw rods 21 are rotatably installed in the two position adjusting frames 5, the adjusting screw nuts 22 are threadedly sleeved on the two adjusting screw rods 21, and the adjusting screw nuts 22 are fixedly connected with the sliding frames 6.

[0034] As shown, the hand wheels 28 are coaxially and fixedly connected with the adjusting screw rods 21 and are rotatably installed on the two position adjusting frames 5.

[0035] Specifically, when the relative positions between the sliding frames 6 and the position adjusting frames 5 are adjusted, the hand wheels 28 at the corresponding positions are rotated to drive the corresponding adjusting screw rods 21 to rotate, so that the sliding frames 6 are driven to move in the position adjusting frames 5 through the adjusting screw nuts 22.

[0036] As shown above, Figure 6 As shown, the positioning part comprises housings 23, positioning rollers 24 and fourth driving members 26, the housings 23 are fixedly installed on the device frame 1 and the two position adjusting frames 5, the positioning rollers 24 are fixedly installed on one end of the bidirectional screw rod 19 and the ends of the two adjusting screw rods 21, the annular positioning grooves 25 are formed in the positioning rollers 24, and the two fourth driving members 26 are symmetrically and fixedly installed on each housing 23, the output ends of the fourth driving members 26 are fixedly installed with fixed frames 27, and the fixed frames 27 are adapted to the annular positioning grooves 25.

[0037] Specifically, when the bidirectional screw rod 19 or the adjusting screw rod 21 is rotated, the corresponding positioning roller 24 is driven to rotate, when it is needed to lock the position of the bidirectional screw rod 19 or the adjusting screw rod 21, the two fourth driving members 26 on the housing 23 at the corresponding position are turned on, the corresponding fixed frames 27 are driven to move by the fourth driving members 26, until the fixed frames 27 enter the annular positioning grooves 25 on the positioning rollers 24, the position of the positioning roller 24 is locked by friction, so that the rotation of the corresponding bidirectional screw rod 19 or adjusting screw rod 21 is fixed.

[0038] Preferably, the first driving member 10, the second driving member 14, the third driving member 17 and the fourth driving member 26 are in the form of electric cylinders.

[0040] After the two side plates 29 are clamped, the installation position of the cross beam 30 is determined according to the model of the cushion framework, generally, the cross beam 30 is provided with two, that is, the front end and the rear end installed between the two side plates 29, then the corresponding welding clamp 4 is installed at the corresponding position on the assembly frame 3, and the corresponding cross beam 30 is installed on the welding clamp 4, at this time, the welding positions at the two ends of the cross beam 30 correspond to the welding positions of the side plates 29, and the distances between the two ends of the cross beam 30 and the corresponding side plates 29 are the same.
