Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically to an automotive seat fixture for frame welding. Background Technology

[0002] Car seats are seats used when riding in a car. They are usually composed of a seat frame and a padding layer that covers the outside of the seat frame. Most existing seat frames are one-piece stamped parts. However, stamped parts also have some disadvantages. For example, due to the thinness of the frame body, stamped parts often have insufficient structural strength. In order to increase the structural strength of the seat frame, it is usually necessary to weld some reinforcing ribs at the bottom of the seat frame. At this time, welding fixtures are required.

[0003] According to a public notice (Announcement No.: CN222492815U), the aforementioned application uses eight clamping components to clamp and fix the car seat frame at multiple points. At the same time, the supporting mechanism can reasonably arrange the positions of the clamping components, so that the horizontal seat cushion frame and the vertical backrest frame can be fixed simultaneously, which facilitates subsequent welding and improves the use effect.

[0004] However, since the backrest tilt angle of the seat frame varies for different types of car models, the aforementioned automotive seat frame welding fixture cannot meet the requirements of the backrest tilt angle for different types of car models. Utility Model Content

[0005] The purpose of this invention is to provide an automotive seat clamp for frame welding, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car seat clamp for frame welding, comprising a base, a turntable rotatably connected to the surface of the base, multiple arrayed positioning grooves on the side wall of the turntable, a placement plate fixedly connected to the surface of the base, a bracket hinged to the surface of the placement plate, two symmetrically arranged L-plates fixedly connected to the surfaces of the bracket and the placement plate, a clamp body disposed on the surface of the L-plate, an adjustment component disposed on the side wall of the placement plate, the adjustment component comprising two sets of grooves, the two sets of grooves respectively disposed on both sides of the placement plate, a movable seat slidably connected inside the two sets of grooves, a through hole disposed on the side wall of one set of movable seats, and a lead screw threadedly connected to the through hole, the end of the lead screw rotatably connected to the inner wall of the groove, a support rod hinged to the side wall of the movable seat, the end of the support rod hinged to the side wall of the L-plate.

[0007] Preferably, the surface of the base is provided with a sliding groove, and a limiting component is provided inside the sliding groove. The limiting component includes a movable plate, which is slidably connected inside the sliding groove. A through hole is provided on the side wall of the movable plate, and a threaded rod is threadedly connected in the through hole. An insert is fixedly connected to the side wall of the movable plate, and the insert is inserted into the positioning groove.

[0008] Preferably, the clamp body includes a cylinder, a clamping plate, and a guide rod. The cylinder is fixedly connected to the surface of the L-plate, and the cylinder passes through and is slidably connected to the side wall of the L-plate. The output end of the cylinder is fixedly connected to the clamping plate.

[0009] Preferably, another set of the movable seats has a through hole on its side wall, and a crossbar is slidably connected in the through hole, the end of the crossbar being fixedly connected to the side wall of the groove.

[0010] Preferably, a motor is fixedly connected to the side wall of the placement plate, the output shaft of the motor passes through and is rotatably connected to the inner wall of the groove, and the output shaft of the motor is fixedly connected to the end of the lead screw.

[0011] Preferably, the threaded rod is rotatably connected to the side wall of the base, one end of the threaded rod is rotatably connected to the inner wall of the slide groove, and the other end of the threaded rod is fixedly connected to a rotating wheel.

[0012] Preferably, the guide rod is fixedly connected to the back of the clamping plate, and the guide rod is slidably connected to the side wall of the L-plate.

[0013] Compared with the prior art, the present invention provides an automotive seat clamp for frame welding, which has the following advantages:

[0014] 1. This automotive seat fixture for frame welding drives a lead screw to rotate via the output shaft of a motor. Since the lead screw is threadedly connected to a movable seat on one side, the movable seat moves laterally along the groove. The movable seat on the other side moves laterally synchronously via a crossbar. The lateral movement of the two sets of movable seats transmits power through a hinged support rod, pushing or pulling the L-plate, causing the bracket to swing around the hinge point with the placement plate until it is adjusted to a position that matches the tilt angle of the seat frame back, thus adapting to the personalized welding requirements of seat frames for different car models.

[0015] 2. This automotive seat fixture for frame welding involves manually rotating a rotary wheel to rotate a threaded rod. Since the threaded rod is threadedly connected to the through hole of the moving plate, the moving plate moves laterally along the slide groove of the base, causing the insert block to be pulled out of the positioning groove of the turntable, releasing the locking state of the turntable. The turntable can then be manually rotated to the desired welding position. The side wall of the turntable is provided with multiple sets of evenly distributed positioning grooves, allowing for the selection of a suitable position according to welding requirements.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a car seat fixture for frame welding, including a base 1, a turntable 2 rotatably connected to the surface of the base 1, and multiple arrayed positioning grooves 21 on the side wall of the turntable 2. The turntable 2 can rotate on the surface of the base 1, thereby realizing the rotation of the seat frame and facilitating the welding operation of the seat frame. The positioning grooves 21 cooperate with the limiting component 9 to position the turntable 2. A placement plate 3 is fixedly connected to the surface of the base 1, and a bracket 4 is hinged to the surface of the placement plate 3. The placement plate 3 and the bracket 4 are used to support the bottom and back of the seat frame, and the bracket 4 can be adjusted angularly along the hinge point with the placement plate 3, so as to facilitate adjustment according to the tilt angle of the back of the seat frame. Two sets of symmetrically arranged L-plates 5 are fixedly connected to the surfaces of the bracket 4 and the placement plate 3. The L-plates 5 are used to fix the fixture body 6. The fixture body 6 is provided on the surface of the L-plates 5. The fixture body 6 includes a cylinder 61, a clamping plate 62, and a guide. The guide rod 63 and cylinder 61 are fixedly connected to the surface of L plate 5. Cylinder 61 is slidably connected to the side wall of L plate 5. The output end of cylinder 61 is fixedly connected to clamping plate 62. Guide rod 63 is fixedly connected to the back of clamping plate 62. Guide rod 63 is slidably connected to the side wall of L plate 5. The output end of cylinder 61 is connected to clamping plate 62. The clamping plate 62 is driven to move by air pressure to clamp or release the seat frame. During the movement, clamping plate 62 is guided by guide rod 63 to ensure accurate guidance during the movement and avoid shaking.

[0022] like Figures 1-4As shown, the side wall of the placement plate 3 is provided with an adjustment assembly 7, which includes two sets of grooves 71. The two sets of grooves 71 are respectively opened on both sides of the placement plate 3. The interior of each set of grooves 71 is slidably connected to a movable seat 72. One set of movable seats 72 has a through hole on its side wall, and a lead screw 73 is threaded into the through hole. The end of the lead screw 73 is rotatably connected to the inner wall of the groove 71. The movable seat 72 converts the rotational motion of the lead screw 73 into linear motion, driving the support rod 75 to swing, thereby adjusting the tilt angle of the bracket 4. The other set of movable seats 72 has a through hole on its side wall, and a crossbar 74 is slidably connected into the through hole. The end of the crossbar 74 is fixedly connected to the side wall of the groove 71. The crossbar 74 is a guide shaft for the other movable seat 72, so that the other movable seat 72 moves along the axis of the crossbar 74, ensuring that the two sets of movable seats 72 move synchronously and avoiding jamming. A support rod 75 is hinged to the side wall of the movable seat 72. The end of the support rod 75 is hinged to the side wall of the L-plate 5. The support rod 75 connects the movable seat 72 and the L-plate 5, transmitting lateral movement force and adjusting the tilt angle of the bracket 4. A motor 76 is fixedly connected to the side wall of the placement plate 3. The output shaft of the motor 76 passes through and is rotatably connected to the inner wall of the groove 71. The output shaft of the motor 76 is fixedly connected to the end of the lead screw 73. The motor 76 drives the lead screw 73 to rotate, realizing the automatic adjustment of the angle of the bracket 4. This is suitable for the welding process requirements of different models of seat frames, improving production efficiency and flexibility.

[0023] like Figures 1-4 As shown, a groove 8 is formed on the surface of the base 1. A limiting component 9 is installed inside the groove 8. The limiting component 9 includes a movable plate 91, which is slidably connected inside the groove 8. A through hole is formed on the side wall of the movable plate 91, and a threaded rod 92 is threadedly connected to the through hole. The threaded rod 92 is rotatably connected to the side wall of the base 1. One end of the threaded rod 92 is rotatably connected to the inner wall of the groove 8. The threaded rod 92 drives the movable plate 91 to move laterally. The operation is simple, and the self-locking property of the threaded rod 92 ensures that the movable plate 91 will not loosen on its own after locking. A rotating wheel 93 is fixedly connected to the other end of the threaded rod 92. An insert block 94 is fixedly connected to the side wall of the movable plate 91. The insert block 94 is inserted into the positioning groove 21. The rotating wheel 93 allows the operator to rotate the threaded rod 92, driving the movable plate 91 to move laterally, realizing the insertion and separation of the insert block 94 from the positioning groove 21, and realizing the positioning or unlocking of the turntable 2.

[0024] In this invention, during use, the rotary wheel 93 is manually rotated, causing the threaded rod 92 to rotate. Since the threaded rod 92 is threadedly connected to the through hole of the moving plate 91, the moving plate 91 moves laterally along the sliding groove 8 of the base 1, causing the insert block 94 to be pulled out of the positioning groove 21 of the turntable 2, releasing the locked state of the turntable 2. The turntable 2 is then manually rotated to the desired welding position (such as welding positions at different angles). The side wall of the turntable 2 is provided with multiple sets of evenly distributed positioning grooves 21, allowing selection of a suitable position according to welding requirements.

[0025] Based on the required tilt angle of the seat frame back, motor 76 is started. The output shaft of motor 76 drives lead screw 73 to rotate. Since lead screw 73 is threadedly connected to one movable seat 72, the movable seat 72 moves laterally along groove 71; the other movable seat 72 is guided by crossbar 74 and moves laterally synchronously (crossbar 74 restricts its movement to only along the axis to avoid jamming). The lateral movement of the two sets of movable seats 72 transmits power through hinged support rod 75, pushing or pulling L plate 5, causing bracket 4 to swing around the hinge point with placement plate 3 until it is adjusted to a position matching the tilt angle of the seat frame back. After motor 76 stops, the self-locking property of lead screw 73 ensures the angle is fixed, preventing shaking during welding.

[0026] When cylinder 61 is activated (compressed air is connected), the piston rod extends, pushing clamping plate 62 to move horizontally towards the seat frame. Guide rod 63 on the back of clamping plate 62 slides along the guide hole of L-plate 5, ensuring a smooth and non-deviation-prone horizontal movement. After clamping plate 62 contacts the seat frame, a set air pressure maintains the clamping force, firmly fixing the bottom and back surfaces of the frame.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
