Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a spot welding device for automotive seat cushion frames. Background Technology

[0002] Car seat cushions are essential products for protecting car seats and maintaining human health. The seat cushion frame is a support structure embedded inside the seat cushion, primarily bearing the weight of the body and maintaining its structural shape. The frame determines the overall contour of the seat (such as the backrest curvature and cushion thickness), preventing sagging or deformation due to long-term use. A typical car seat cushion frame consists of an outer frame 24 and an inner frame panel 23. Figure 1 As shown.

[0003] The installation of the outer frame and inner plate of the seat frame requires spot welding at the joint to ensure a strong connection. For spot welding of the seat frame, existing technology CN222269070U proposes a seat frame spot welding device, including a main seat. A processing frame is fixedly connected to the middle of the main seat. A welding mechanism and a testing mechanism are connected to the inner side of the processing frame via a lifting mechanism. A tooling seat is installed on the upper side of the main seat via a moving mechanism. The welding of the seat frame is achieved through the coordinated work of these mechanisms.

[0004] The aforementioned device places the required frame onto the fixture for spot welding during the welding process. However, before spot welding the frame, since the outer frame and inner plate of the frame are not fixed, the relative position between the outer frame and the inner plate can easily shift due to inertia or mechanical vibration when the fixture moves, resulting in misalignment. This misalignment will cause the subsequent spot welding points to deviate, making it impossible to weld the outer frame and inner plate of the frame together. To address this issue, we provide a spot welding device for automotive seat cushion frames to solve the aforementioned problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 In this embodiment of the present invention, a spot welding device for a car seat frame includes a base plate 1. Support columns 2 are fixedly connected to the four corners of the upper surface of the base plate 1. An mounting plate 3 is fixedly connected between the upper ends of the support columns 2. A first sliding groove 22 is formed in the middle of the mounting plate 3. Second sliding grooves 20 are formed in the middle of both sides of the mounting plate 3. The second sliding grooves 20 and the first sliding grooves 22 are perpendicular to each other. Second adjusting support plates 4 are slidably connected within each of the second sliding grooves 20. First adjusting support plates 5 are slidably connected to both ends of the first sliding grooves 22. Supporting slot blocks 9 for placing the outer frame 24 of the frame are fixedly connected to the upper ends of both the second adjusting support plates 4 and the first adjusting support plates 5. The slots at the upper ends of the supporting slot blocks 9 are V-shaped. The supporting slot blocks 9 allow the outer frame 24 of the frame to be placed during use. The V-shaped slots at the upper ends of the supporting slot blocks 9 restrict the outer frame 24 of the frame, preventing it from moving arbitrarily.

[0025] The first sliding groove 22 is provided with a first adjustment component for adjusting the position of the two first adjustment support plates 5. The first adjustment component includes a first bidirectional screw 19, which is rotatably connected inside the first sliding groove 22. The threads at both ends of the first bidirectional screw 19 are respectively threaded to the two first adjustment support plates 5. When it is necessary to adjust the distance between the two first adjustment support plates 5, the first bidirectional screw 19 can be rotated through the corresponding handle 6. The rotation of the first bidirectional screw 19 can drive the two first adjustment support plates 5 to move closer or further apart, thereby realizing the adjustment of the distance between the two first adjustment support plates 5.

[0026] The lower end of the mounting plate 3 is provided with a second adjustment component for adjusting the position of the second adjustment support plate 4. The second adjustment component includes a second bidirectional screw 21, which is rotatably connected to the position below the second sliding groove 20 by a support. The threads at both ends of the second bidirectional screw 21 are respectively threaded to the bottom of the two second adjustment support plates 4. A handle 6 is fixedly connected to the connecting shaft head of one end of the first bidirectional screw 19 and the second bidirectional screw 21 at the position where it protrudes from the mounting plate 3. When it is necessary to adjust the distance between the two second adjustment support plates 4, the second bidirectional screw 21 can be rotated through the corresponding handle 6. The rotation of the second bidirectional screw 21 can drive the two second adjustment support plates 4 to move closer or further apart, thereby realizing the adjustment of the distance between the two second adjustment support plates 4.

[0027] The mounting plate 3 is also provided with a fixing component for fixing the inner plate 23 of the frame. The fixing component includes a perforated plate 7, which is fixedly connected to the two sides of the first adjusting support plate 5. T-shaped rails 12 are fixedly connected to both sides of the mounting plate 3. A sliding seat 18 is fixedly connected to the end of the perforated plate 7 away from the first adjusting support plate 5. The sliding seat 18 is slidably connected to the T-shaped rail 12. A sliding sleeve 17 is slidably connected to the perforated plate 7. The sliding sleeve 17 is provided with bolts 14 that mate with the round holes on the perforated plate 7. One side of the sliding sleeve 17 is fixedly connected to... A vertical plate 16 is provided, and a clamping component is provided on the vertical plate 16 to press down the inner plate 23 of the frame. The clamping component can fix the inner plate 23 of the frame to the outer frame 24 of the frame. At the same time, the sliding sleeve 17, the perforated plate 7 and the bolt 14 can adjust the position of the vertical plate 16. When adjusting, first remove the bolt 14, then slide the sliding sleeve 17 to make the corresponding adjustment. After the adjustment is completed, insert the bolt 14 into the corresponding hole on the perforated plate 7 to lock it. This allows the clamping position to be adjusted according to the spot welding position during use, so as to avoid the clamping position from coinciding with the spot welding position and affecting the spot welding.

[0028] The clamping assembly includes a folded pressure plate 8, which is rotatably connected to the upper end of the upright plate 16. An electric cylinder 15 is rotatably connected to the bottom of the upright plate 16. The output end of the electric cylinder 15 is rotatably connected to one end of the folded pressure plate 8, and a pressure head 13 is fixedly connected to the other end of the folded pressure plate 8. When clamping the inner plate 23 of the skeleton, the output end of the electric cylinder 15 moves to drive the folded pressure plate 8 to flip, thereby pressing the pressure head 13 onto the inner plate 23 of the skeleton, thus fixing the inner plate 23 of the skeleton.

[0029] A spot welding assembly for spot welding is also provided on one side of the base plate 1; the spot welding assembly includes a mounting platform 11, which is located on one side of the base plate 1, and a welding robot 10 for spot welding is mounted on the mounting platform 11; the welding robot 10 can perform spot welding on each spot welding position of the inner frame 23 and the outer frame 24 of the skeleton according to a pre-set program during operation.

[0030] The working principle of this utility model is as follows: During operation, the outer frame 24 is first placed on multiple support slots 9, and then the corresponding inner frame plate 23 is placed on the outer frame 24. After placement, the output end of the electric cylinder 15 drives the folding pressure plate 8 to flip. The flipping of the folding pressure plate 8 drives the pressure head 13 to move, so that the pressure head 13 presses on the inner frame plate 23 to fix the inner frame plate 23. During welding, the welding robot 10 performs spot welding on each spot welding position of the inner frame plate 23 and the outer frame 24 according to the preset program. After spot welding is completed, the output end of the electric cylinder 15 retracts and lifts the pressure head 13. Then the spot-welded car seat frame can be taken out.

[0031] The first and second adjustment components are set up at the same time, which can adjust the positions of the first adjustment support plate 5 and the second adjustment support plate 4 respectively during use, so that the position of the support groove block 9 can be adjusted according to the size of the car seat frame, so as to be suitable for spot welding of car seat frames of different sizes.

[0032] The welding robot 10 and electric cylinder 15 used in this application are both existing technologies, and their principles and programming methods are well known to those skilled in the art, so they will not be elaborated on here.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
