Specific implementation manner

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] During actual production of the saddle, the overall contour of the saddle is triangular, with a wider rear seat and a narrower front seat, and curved surfaces are provided on both sides for transition. When the existing equipment clamps the saddle from both sides with two clamping plates, since the front and rear seats of the saddle are not on the same horizontal plane, it will cause the clamping plates to be difficult to provide sufficient support for the saddle, and it is impossible to stably clamp the saddle. The risk of the saddle sliding and falling is relatively large, affecting the assembly of the leather and the saddle.

[0022] To solve the defects existing in the above clamping device during the process of fixing the saddle, please refer to Figures 1 - 4 , a clamping device for connecting the leather of an electric vehicle saddle provided by the present invention can perform three-point clamping on the saddle from three directions, providing more uniform and stable support for the saddle, preventing the saddle from falling during the assembly process, and ensuring the smooth assembly of the saddle and the leather. The clamping device is based on a base 1, and a leather fixing piece 5 is arranged on the base 1. The leather fixing piece 5 is used to fix the leather on the base 1, and brackets 2 are installed on both sides of the top of the base 1. A pressing plate 4 is slidably installed up and down between the two brackets 2. A fixed seat 10 is fixedly installed on one side of the bottom of the pressing plate 4. A positive screw rod 11 is threadedly connected inside the fixed seat 10. Steering seats 8 are symmetrically rotatably arranged on the other side of the bottom of the pressing plate 4. A side screw rod 9 is threadedly connected inside the steering seat 8. Clamping heads 12 are installed at the ends of the side screw rod 9 and the positive screw rod 11. Rotating the fixed seat 10 and the side screw rod 9 can drive the three clamping heads 12 to clamp the saddle, forming three-point clamping. Compared with the traditional two clamping plates, the three clamping heads 12 can provide more stable supporting force for the saddle.

[0023] Since the outer contours of saddles of different specifications are different and the radian of the curved surfaces on both sides is also different, in order to enable the two clamping heads 12 to be applicable to saddles of different specifications, an adjusting member 7 for driving the two swivel seats 8 to rotate in opposite directions is provided on one side of the top of the pressure plate 4. Among them, the two rotating shafts 71 are respectively fixedly connected to the tops of the two swivel seats 8. The upper ends of the rotating shafts 71 pass through the pressure plate 4 and are fixedly sleeved with gears 72, and the rotating shafts 71 are rotatably connected to the pressure plate 4. By rotating the two rotating shafts 71, the two swivel seats 8 can be driven to rotate. The rotation of the two swivel seats 8 can adjust the orientations of the two side lead screws 9, facilitating the adjustment of the clamping heads 12 to the optimal angles to clamp saddles of different specifications.

[0024] In order to enable the two swivel seats 8 to be adjusted synchronously, a first bidirectional screw 73 is rotatably installed on one side of the top of the pressure plate 4. The threads on the outer surface of the first bidirectional screw 73 are two sections with opposite helix directions. A support for the rotation of the first bidirectional screw 73 is provided on the pressure plate 4. Both ends of the first bidirectional screw 73 are threadedly connected with toothed plates 74. The two toothed plates 74 are respectively meshed with the two gears 72, and the toothed plates 74 are slidably connected to the pressure plate 4. One end of the first bidirectional screw 73 is fixedly connected with a knob 75. Rotating the knob 75 can drive the first bidirectional screw 73 to rotate. The rotation of the first bidirectional screw 73 can drive the two toothed plates 74 to slide in opposite directions. The sliding of the two toothed plates 74 in opposite directions can drive the two gears 72 to rotate in opposite directions, thereby driving the two swivel seats 8 to rotate synchronously to adjust the orientation.

[0025] Since the leather may shift when the saddle is assembled on the leather, to solve this technical problem, referring to Figure 3 as shown, among which, the two suspension frames 51 are respectively fixedly installed on the inner sides of the two brackets 2, and a pressing block 52 is rotatably sleeved outside the suspension frame 51. One end of the pressing block 52 is rotatably installed with an adapting roller 54, and the other end of the pressing block 52 is provided with an arc-shaped pressing surface. The top of the base 1 is symmetrically and slidably installed with an extrusion table 55. The extrusion table 55 abuts against the adapting roller 54. The adapting roller 54 is provided with a slope surface. The sliding of the adapting roller 54 can squeeze the pressing block 52 to rotate. The rotation of the pressing block 52 drives the arc-shaped pressing surface to press and fix the leather. A counterweight block is arranged inside the adapting roller 54. When the extrusion table 55 slides out from the bottom of the pressing block 52, the pressing block 52 can rotate by the gravity of the counterweight block, causing the adapting roller 54 to rotate downward and the arc-shaped pressing surface to lift upward, facilitating the loading and unloading operations of the leather.

[0026] In order to facilitate the synchronous rotation of the two pressing blocks 52 to achieve the pressing and loosening of the leather, a two-way screw rod two 56 is rotatably installed inside the base 1. The threads on the outer surface of the two-way screw rod two 56 are two sections with opposite helix directions. The bottoms of the two extrusion platforms 55 are respectively threadedly connected to the two ends of the two-way screw rod two 56. One end of the two-way screw rod two 56 passes through the base 1 and is fixedly connected to a handle 53. Rotating the handle 53 facilitates driving the rotation of the two-way screw rod two 56. The rotation of the two-way screw rod two 56 can drive the two extrusion platforms 55 to slide in opposite directions, and further drive the two pressing blocks 52 to press the leather from both sides of the leather.

[0027] Refer to Figure 1 As shown, a connecting rod 3 is commonly installed at the tops of the two brackets 2. A hydraulic cylinder 6 is fixedly installed at the bottom of the connecting rod 3. The output end of the hydraulic cylinder 6 is fixedly connected to a pressing plate 4. Driving the hydraulic cylinder 6 can drive the pressing plate 4 to press down. The pressing plate 4 drives the saddle fixed on the pressing plate 4 to press down, so that the saddle is connected and assembled with the leather.
