[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] like Figure 1As shown below, the steps and functions of an automotive sheet metal manufacturing process will be explained in detail.

[0043] An automotive sheet metal manufacturing process includes the following steps:

[0044] Step 1: Clamp the sheet metal using the pressure plate 25, and drive the grinding cavity 73 to move and rotate;

[0045] Step 2: The grinding cavity 73 drives the multiple grinding discs 74 on it to rotate, and the multiple grinding discs 74 contact the sheet metal to grind it;

[0046] Step 3: Adjust the shape of the grinding cavity 73, thereby changing the distribution of multiple grinding discs 74 and adjusting the grinding shape.

[0047] like Figures 2 to 12 As shown, in order to facilitate the implementation of an automotive sheet metal production process, an automotive sheet metal production device is designed. The structure and function of the automotive sheet metal production device are described in detail below.

[0048] An automotive sheet metal production apparatus includes an apparatus support 11, a lead screw 12 rotatably connected to the apparatus support 11, and a power mechanism I for driving the lead screw 12 to rotate fixedly connected to the apparatus support 11. The power mechanism I is preferably a servo motor.

[0049] Two rotating disks 21 are rotatably connected to the device bracket 11. Each rotating disk 21 is fixedly connected to a telescopic mechanism I 22. Each telescopic mechanism I 22 is fixedly connected to two telescopic mechanisms II 23 at its telescopic end. Each telescopic mechanism II 23 is fixedly connected to a telescopic mechanism III 24 at its telescopic end. Each telescopic mechanism III 24 is fixedly connected to a pressure plate 25 at its telescopic end.

[0050] A power mechanism II for driving the rotating disk 21 to rotate is fixedly connected to the device bracket 11. The power mechanism II is preferably a servo motor.

[0051] A sliding block 31 is slidably connected to the device bracket 11. The sliding block 31 is threadedly connected to the lead screw 12. A telescopic mechanism IV 32 is fixedly connected to the sliding block 31. A lifting bracket 33 is fixedly connected to the telescopic end of the telescopic mechanism IV 32.

[0052] A rotating disk 41 is rotatably connected to the lifting bracket 33, a rotating ring 42 is rotatably fixed on the rotating disk 41, and a power mechanism Ⅲ that drives the rotating disk 41 to rotate is fixedly connected to the lifting bracket 33. The power mechanism Ⅲ is preferably a servo motor.

[0053] An intermittent ball I 52 is fitted on the rotating disk 41 with a clearance fit. A pulling disk 51 is fixedly connected to the intermittent ball I 52. A grinding bracket 53 is fixedly connected to the lower end of the intermittent ball I 52.

[0054] Multiple telescopic mechanisms V60 are fixedly connected to the rotating ring 42, and a compression spring I is fixedly connected between the telescopic end of each telescopic mechanism V60 and the pulling plate 51.

[0055] Two support cylinders 71 are slidably connected to the grinding bracket 53. A compression spring II is fixedly connected between the support cylinders 71 and the grinding bracket 53. A rotating plate 72 is rotatably connected to the inner side of each of the two support cylinders 71. A power mechanism V for driving the rotating plate 72 to rotate is fixedly connected to the support cylinder 71. The power mechanism V is preferably a servo motor. A grinding cavity 73 is fixedly connected between the two rotating plates 72. Multiple grinding discs 74 are arranged on the grinding cavity 73. Multiple connecting holes 75 are provided on each of the two support cylinders 71. A rotating cavity 76 is rotatably connected to each of the two support cylinders 71. A connecting pipe 77 is fixedly connected to each of the two rotating cavities 76. The rotating cavity 76 is connected to the support cylinder 71 through the connecting holes 75.

[0056] The polishing cavity 73 is made of elastic material;

[0057] Two telescopic mechanisms VI81 are fixedly connected to the grinding bracket 53. The two telescopic mechanisms VI81 are slidably connected to the two support cylinders 71 respectively. A movable disk 82 is fixedly connected to the telescopic end of each of the two telescopic mechanisms VI81. Multiple telescopic mechanisms VII83 are fixedly connected to each of the two movable disks 82. An intermittent cavity 84 is fixedly connected to the telescopic end of each telescopic mechanism VII83. An intermittent ball II 85 is provided on each intermittent cavity 84. The intermittent ball II 85 can contact the inside of the grinding cavity 73.

[0058] When using, such as Figure 2 As shown, the sheet metal to be processed is placed between multiple pressure plates 25, and the telescopic mechanism III 24 is activated. The telescopic mechanism III 24 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 24 drives the pressure plates 25 to move, and the sides of the sheet metal are clamped by the multiple pressure plates 25.

[0059] Furthermore, since the sheet metal to be ground has different shapes, telescopic mechanisms I22 and II23 are activated. Telescopic mechanisms I22 and II23 can be hydraulic cylinders or electric push rods. The telescopic ends of telescopic mechanisms I22 and II23 drive telescopic mechanism III24 to move, and adjust the clamping position of telescopic mechanism III24 to meet different usage requirements.

[0060] Furthermore, the power mechanism II is activated, and the output shaft of the power mechanism II begins to rotate. The output shaft of the power mechanism II drives the rotating disk 21 to rotate, the rotating disk 21 drives the telescopic mechanism I 22 to rotate, the telescopic mechanism I 22 drives the telescopic mechanism II 23 to rotate, the telescopic mechanism II 23 drives the telescopic mechanism III 24 to move, the telescopic mechanism III 24 drives the pressure plate 25 to move, and the pressure plate 25 drives the sheet metal to move, thereby adjusting the orientation of the sheet metal to meet different usage requirements.

[0061] Furthermore, during the processing, when the sheet metal needs to move laterally, the telescopic mechanism II23 is activated, causing the telescopic end of the telescopic mechanism II23 to drive the telescopic mechanism III24 to move. The telescopic mechanism III24 then drives the pressure plate 25 to move, thereby adjusting the position of the sheet metal. In other words, activating the telescopic mechanism II23 can not only adjust the clamping position but also adjust the position of the sheet metal during processing. That is, the telescopic ends of multiple telescopic mechanisms II23 move to the same side.

[0062] After the sheet metal is clamped, the power mechanism I is started. The output shaft of the power mechanism I drives the lead screw 12 to rotate. When the lead screw 12 rotates, it drives the sliding block 31 to move through the thread. The sliding block 31 drives the telescopic mechanism IV 32 to move. The telescopic mechanism IV 32 drives the lifting bracket 33 to move. The lifting bracket 33 drives the rotating disk 41 to move. The rotating disk 41 drives the intermittent ball I 52 to move. The intermittent ball I 52 drives the grinding bracket 53 to move. The grinding bracket 53 drives the grinding cavity 73 to move, thereby adjusting the grinding position of the grinding cavity 73.

[0063] Furthermore, the telescopic mechanism IV32 is activated. The telescopic mechanism IV32 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV32 drives the lifting bracket 33 to move. The lifting bracket 33 drives the rotating disk 41 to move. The rotating disk 41 drives the intermittent ball I 52 to move. The intermittent ball I 52 drives the grinding bracket 53 to move. The grinding bracket 53 drives the grinding cavity 73 to move, thereby adjusting the grinding height of the grinding cavity 73.

[0064] Furthermore, the power mechanism III is started, and the output shaft of the power mechanism III begins to rotate. The output shaft of the power mechanism III drives the rotating disk 41 to rotate, the rotating disk 41 drives the rotating ring 42 to rotate, the rotating ring 42 drives the pulling disk 51 to rotate, the pulling disk 51 drives the grinding bracket 53 to rotate, and the grinding bracket 53 drives the grinding cavity 73 to move, adjusting the direction of the grinding cavity 73.

[0065] Furthermore, the telescopic mechanism V60 is activated. The telescopic mechanism V60 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism V60 moves the pulling plate 51 through the compression spring I. The pulling plate 51 drives the intermittent ball I 52 to move. The intermittent ball I 52 drives the grinding bracket 53 to move. The grinding bracket 53 drives the grinding cavity 73 to move, thereby adjusting the tilt direction of the grinding cavity 73.

[0066] Furthermore, depending on different usage needs, the telescopic mechanism V60 at different positions can be activated to tilt the grinding chamber 73 in different directions to meet different grinding requirements.

[0067] When the power mechanism V is started, the output shaft of the power mechanism V begins to rotate. The output shaft of the power mechanism V drives the rotating plate 72 to rotate, the rotating plate 72 drives the grinding cavity 73 to rotate, and the grinding cavity 73 drives the multiple grinding discs 74 on it to move. The multiple grinding discs 74 contact the sheet metal and grind the sheet metal.

[0068] Furthermore, such as Figure 10 As shown, when it is necessary to grind curved surfaces, i.e. convex or concave curved surfaces, the air pump is pre-connected to the connecting pipe 77. Gas is introduced into the connecting pipe 77 through the air pump, and the gas in the connecting pipe 77 enters the support cylinder 71 through the connecting hole 75, and then enters the grinding chamber 73, thereby increasing the pressure inside the grinding chamber 73 and causing the grinding chamber 73 to deform.

[0069] Furthermore, an air pump can be used to evacuate the grinding chamber 73, creating negative pressure in the grinding chamber 73, which in turn causes the grinding chamber 73 to deform.

[0070] Furthermore, in order to control the deformation generated by the grinding cavity 73, the telescopic mechanism VI81 is activated. The telescopic mechanism VI81 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism VI81 drives the moving disk 82 to move, the moving disk 82 drives the telescopic mechanism VII83 to move, the telescopic mechanism VII83 drives the intermittent cavity 84 to move, and the intermittent cavity 84 drives the intermittent ball II 85 to move, thereby adjusting the position of the intermittent ball II 85 in the grinding cavity 73.

[0071] Furthermore, the telescopic mechanism VII83 is activated. The telescopic mechanism VII83 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism VII83 drives the intermittent cavity 84 to move. The intermittent cavity 84 drives the intermittent ball II 85 to move. The intermittent ball II 85 contacts the grinding cavity 73 and supports the grinding cavity 73 from the inside to meet different usage requirements.

[0072] Furthermore, by cooperating with each other, multiple intermittent balls II 85 on the two moving disks 82 can compress the grinding cavity 73 into different shapes. For example, when the two moving disks 82 move to the two sides of the middle of the grinding cavity 73, multiple intermittent balls II 85 extend outward to support the grinding cavity 73, causing the two sides of the middle of the grinding cavity 73 to bulge outward. At the same time, the air pump evacuates the grinding cavity 73, creating negative pressure in the grinding cavity 73, which in turn causes the middle of the grinding cavity 73 to concave inward, thus grinding the convex surface. Meanwhile, multiple intermittent balls II 85 on both sides extend to different heights, thus grinding the asymmetrical convex surface.

[0073] Furthermore, multiple intermittent balls II 85 on a moving disk 82 are used to press the center of the grinding cavity 73, causing the center of the grinding cavity 73 to bulge outward, thereby grinding the concave surface. At the same time, another moving disk 82 moves to the side and supports the inner wall of the grinding cavity 73 through multiple intermittent balls II 85, thereby grinding the asymmetrical concave surface. Simultaneously, in conjunction with an air pump, the pressure inside the grinding cavity 73 is adjusted, and the shape of the grinding cavity 73 is adjusted to meet more grinding needs.

[0074] Furthermore, such as Figure 10 As shown, the grinding cavity 73 is provided with multiple staggered grinding discs 74, all of which are fixedly connected to the grinding cavity 73. The grinding cavity 73 may be provided with multiple embedding grooves, the cross-section of which is preferably trapezoidal, and the cross-section of the grinding discs 74 is preferably trapezoidal. The grinding discs 74 are embedded into the embedding grooves, and the embedding grooves can limit the grinding discs 74. When the grinding cavity 73 deforms, it will cause the grinding discs 74 to deform to a certain extent. The multiple grinding discs 74 are staggered, so that when the grinding cavity 73 deforms, the grinding discs 74 can also be fully ground.
