Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for processing steel plates of automobile seats. Background Art

[0002] As one of the basic devices of an automobile, the automobile seat system directly affects the safety and riding comfort of passengers. It is an important safety component of the automobile. The basic structure of the seat is the automobile seat frame, which can be divided into two parts: the seat cushion frame and the backrest frame. The two are independent of each other and are respectively connected to the vehicle body structure. At present, general automobile seat cushion frames are made of stamping steel plates or aluminum alloy materials. When producing and processing the automobile seat cushion frame, in order to facilitate subsequent installation operations, drilling operations are required. The Chinese authorized utility model patent (publication number: CN220560202U) discloses a processing device for an automobile seat frame. After placing the seat frame on the processing table, the device uses a pressing mechanism to press and fix it, preventing the frame from sliding during the processing and improving the processing accuracy.

[0003] The above device still has some deficiencies when in use: In order to better fit the human body curve and meet the riding comfort, the steel plates used in the seat frame are usually designed in irregular shapes. For steel plates with uneven surfaces, the pressing mechanisms in the prior art often have difficulty achieving full and uniform contact with the steel plates to be processed, resulting in the steel plates being prone to movement or shaking during the punching process, seriously affecting the punching accuracy and stability. Therefore, in view of the above situation, a punching device for processing steel plates of automobile seats is proposed. Summary of the Utility Model

[0004] A punching device for processing steel plates of automobile seats proposed by the utility model has the advantage of being able to closely fit the complex contour of the steel plate, ensuring that the steel plate remains stable and immovable during the punching process, thereby improving the punching accuracy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A punching device for processing steel plates of automobile seats includes a base. A processing table is arranged on the top of the base. A pair of hollow slots are opened on the processing table. One side of the inner walls of the pair of hollow slots is rotatably connected with a screw rod. One end of the screw rod penetrates out of the hollow slot. The penetrating end of the screw rod is connected with a knob. A support block is arranged on the screw rod.

[0007] The support block is in an inverted "L" shape. A protrusion is arranged on the support block. A first screw hole is penetrated through the protrusion. The first screw hole is in threaded fit with a first bolt. The bottom end of the first bolt passes through the first screw hole and is connected with a connecting plate. A first positioning rod is arranged at the bottom of the connecting plate.

[0008] The connecting plate is provided with a pair of sliding grooves, and a sliding plate is slidably fitted in each of the pair of sliding grooves. Each of the pair of sliding plates is provided with a through second screw hole.

[0009] A pair of channels are formed in the support block, and a second bolt is fitted in the channels. The second bolt passes through the channels and is in threaded fit with the second screw hole. One end of the second bolt passing through the second screw hole is connected with a second positioning rod.

[0010] Preferably, two through holes are formed in the processing table, and the two through holes are respectively communicated with the hollow groove. The through holes are in fit with the protruding ends of the screw rods.

[0011] Preferably, a moving block is slidably fitted in the hollow groove. The moving block is provided with a threaded hole, and the threaded hole is in threaded fit with the screw rod. The moving block is fixedly connected to the bottom of the support block.

[0012] Preferably, rubber pads are arranged at the bottoms of the first positioning rod and the second positioning rod.

[0013] Preferably, friction surfaces are arranged on the surfaces of the sliding plates slidably fitted with the sliding grooves.

[0014] Preferably, an operating mechanism is arranged on the top of the base.

[0015] The utility model has the following beneficial effects:

[0016] 1. Through the structural design of the support block, the first bolt, the connecting plate, the first positioning rod, the second bolt and the second positioning rod, when punching and positioning the steel plate of the car seat, it can closely fit the complex contour of the steel plate, ensure that the steel plate remains stable and immovable during the punching process, thereby significantly improving the punching accuracy and the finished product rate, and effectively solving the problem that the traditional pressing plate pressing method is not firmly fixed when facing the steel plate with an irregular shape.

[0017] 2. Through the structural design of the screw rod, the channel, the sliding groove and the sliding plate, the positions of the first positioning rod and the sliding plate can be flexibly adjusted, so that the device can easily cope with the positioning of the steel plates of car seats with different shapes and sizes, greatly saving the production preparation time and cost.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-4 , a punching device for processing automotive seat steel plates, including a base 1. A processing table 2 is arranged on the top of the base 1. A pair of hollow grooves 201 are opened on the processing table 2. One side of the inner wall of each of the pair of hollow grooves 201 is rotatably connected with a screw rod 202. One end of the screw rod 202 passes through the hollow groove 201, and the passing end of the screw rod 202 is connected with a knob 203. Two through holes are opened on the processing table 2, and the two through holes are respectively communicated with the hollow grooves 201. The through holes cooperate with the passing ends of the screw rods 202. A moving block is slidably matched in the hollow groove 201. The moving block has a threaded hole, and the threaded hole is threadedly matched with the screw rod 202. The moving block is fixedly connected with the bottom of the support block 3.

[0025] The support block 3 is in an inverted "L" shape. A protrusion 301 is provided on the support block 3. A first screw hole 3010 is penetrated through the protrusion 301. A first bolt 4 is threadedly matched with the first screw hole 3010. The bottom end of the first bolt 4 passes through the first screw hole 3010 and is connected with a connecting plate 5. A first positioning rod 6 is arranged at the bottom of the connecting plate 5.

[0026] The connecting plate 5 has a pair of chutes 501. A sliding plate 7 is slidably matched in each of the pair of chutes 501. Each of the pair of sliding plates 7 has a through second screw hole 701.

[0027] A pair of channels 302 are opened on the support block 3. A second bolt 8 is matched in the channels 302. The second bolt 8 passes through the channel 302 and is threadedly matched with the second screw hole 701. The end of the second bolt 8 passing through the second screw hole 701 is connected with a second positioning rod 9.

[0028] In this embodiment, during use, first adjust the distance between the two support blocks 3 according to the size of the steel plate of the seat frame to be processed. Rotate the knob 203 to drive the screw rod 202 to rotate. The rotation of the screw rod 202 can cause the moving block to move, and then cause the support block 3 to move, thereby completing the adjustment of the distance between the two support blocks 3. Place the steel plate to be processed on the processing table 2. First, rotate the first bolt 4 to make the first bolt 4 descend. The descent of the first bolt 4 causes the connecting plate 5 to descend, and thus the first positioning rod 6 descends. When the surface of the steel plate is uneven and it is difficult to effectively fix it only by the first positioning rod 6, then rotate the second bolt 8 to make the second bolt 8 rotate and descend on the second screw hole 701, so that the second positioning rod 9 further descends to contact the irregular concave surface of the steel plate, further realizing the fixation. And when it is necessary to adjust the optimal positioning position according to the irregular surface of the steel plate, hold the top of the second bolt 8 and apply a pulling force to the side away from the first bolt 4, so that the sliding plate 7 slides in the sliding groove 501, and the position of the second positioning rod 9 can be adjusted accordingly. Then continue with the positioning operation.

[0029] In the above embodiment, the maximum stroke of the second bolt 8 sliding in the channel 302 is the same as the maximum stroke of the sliding plate 7 sliding in the sliding groove 501.

[0030] In this embodiment, as Figure 4 shown, rubber pads are provided at the bottoms of the first positioning rod 6 and the second positioning rod 9.

[0031] In this embodiment, by providing the rubber pads, when the first positioning rod 6 and the second positioning rod 9 position the steel plate of the automotive seat frame, wear on the surface of the steel plate can be avoided.

[0032] In this embodiment, as Figure 4 shown, friction surfaces are provided on the surfaces where the sliding plate 7 and the sliding groove 501 are in sliding fit.

[0033] In this embodiment, by providing the friction surfaces, the friction force between the sliding plate 7 and the sliding groove 501 can be increased, thereby effectively preventing the sliding plate 7 from sliding randomly and affecting the positioning operation. The friction surfaces can be realized in the form of anti-slip patterns.

[0034] In this embodiment, as Figure 1 shown, an operating mechanism 10 is provided on the top of the base 1.

[0035] In this embodiment, the operating mechanism 10 includes a lifting component and a punching component. The punching component is provided on the lifting component. The composition structure of the punching component is the same as that in the prior art (publication number: CN220560202U) which includes a punching head and other related structures for punching processing. The lifting component is the same as the related structure for driving the punching head to lift, and the installation method of the processing table 2 is also the same as that in the prior art, and will not be elaborated here.

[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
