[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1-3 A driver's cab door panel pressing device includes a base 1, a hydraulic pressing mechanism, and a height adjustment mechanism;

[0024] Furthermore, the hydraulic pressing mechanism includes four pressing components arranged in a ring. Each of the four pressing components includes a pressing frame 2 hinged to the top of the base 1, a pressing metal part 3 fixedly connected to the top of the pressing frame 2, and two hydraulic cylinders 4 sequentially hinged between the base 1 and the pressing frame 2.

[0025] Furthermore, the adjustable positioning mechanism includes a support platform 5, a slide groove 6 opened on the top of the support platform 5, a bidirectional screw 7 rotatably installed in the slide groove 6, a motor bracket 8 welded to the side wall of the support platform 5, a servo motor 9 fixed to the side wall of the motor bracket 8 by bolts, two adjusting blocks 10 symmetrically screwed to the two opposite thread ends of the bidirectional screw 7, and two door panel positioning seats 11 symmetrically welded to the top outer wall of the two adjusting blocks 10.

[0026] Furthermore, the outer walls of both adjusting blocks 10 are slidably connected to the slide groove 6, and a set of equally spaced disc springs 12 are installed on the side of each of the two door panel positioning seats 11 that are far apart from each other.

[0027] Furthermore, the output shaft of the servo motor 9 passes through the motor bracket 8 and is coaxially and fixedly connected to one end of the bidirectional screw 7 via a coupling;

[0028] In this specific embodiment: First, the bidirectional screw 7 is rotated forward and backward by the servo motor 9. Then, under the limit of the slide groove 6, the two adjusting blocks 10 will move closer to each other or further away from each other. This allows for flexible adjustment of the distance between the two door panel positioning seats 11 to adapt to the positioning of different specifications of cab door panels.

[0029] Secondly, after adjustment, the cab door panel to be processed is pressed between the two sets of disc springs 12, so that it is stably positioned on the two door panel positioning seats 11. This effectively prevents the position from shifting during the subsequent pressing process, thereby ensuring the pressing quality and pressing efficiency.

[0030] Finally, the edge pressing operation is performed through the edge pressing assembly, that is, the edge pressing metal parts 3 on the edge pressing machine frame 2 are moved by two hydraulic cylinders 4. In this way, the hydraulic power operation can change the cab door panel process from plug welding to one-time edge wrapping, which effectively improves the product quality and product aesthetics.

[0031] Example 2, refer toFigure 2 and Figure 4 This embodiment is an optimization based on Embodiment 1. Specifically, it includes a cab door panel pressing device, and further includes a height adjustment mechanism, which comprises:

[0032] Guide rail 13 and two sliders 15: Guide rail 13 is welded to the top outer wall of base 1, and both sliders 15 are slidably connected to guide rail 13;

[0033] Double-acting cylinder 14: The double-acting cylinder 14 is fixed to the top outer wall of the guide rail 13 by bolts, and the two piston ends of the double-acting cylinder 14 are respectively fixedly connected to the two sliders 15.

[0034] Two linkage diagonal rods 16: The bottom ends of the two linkage diagonal rods 16 are sequentially hinged to the tops of the two sliders 15, and the top ends of the two linkage diagonal rods 16 are both hinged to the bottom of the support platform 5. The two linkage diagonal rods 16 are arranged in a cross-shaped but non-contact configuration.

[0035] In this specific embodiment: the two piston ends of the two-way cylinder 14 control the two sliders 15 to move closer or further apart, and then the two linkage diagonal rods 16 move to control the lifting and lowering of the support platform 5. This allows for flexible adjustment of the processing height of the positioned cab door panel, thereby better adapting to diverse edge pressing processing needs.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
