Description

Technical Field

[0001] This utility model relates to the field of vehicle door processing technology, specifically a lightweight SMC bus cabin door cutting device. Background Technology

[0002] SMC composite materials and their molded products have excellent electrical insulation, mechanical properties, thermal stability, and chemical corrosion resistance. They are widely used in parts such as car bodies, doors, and hoods, making the car body lighter, stronger, and more corrosion-resistant while improving fuel efficiency and safety.

[0003] After the SMC material is molded into a hatch, a cutting device is needed to cut holes in the hatch. However, the hatch is generally curved, and the curve will cause it to wobble during cutting. This wobble will cause the cutting position to deviate from the intended point, resulting in a deviation in the position of the holes. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1-5 As shown, this utility model is a lightweight SMC bus door cutting device, comprising:

[0033] The operating table 100 has a cutting mechanism 200 fixedly connected to its top surface, a fitting groove 110 opened in the middle of the operating table 100, and a lower bracket 120 fixedly connected to its bottom surface.

[0034] The fixing mechanism includes a cylinder 310, a lifting column 320, a connecting rod 330, a lower hanging plate 340, a fixing plate 350, and an arc plate 360.

[0035] Cylinder 310 is fixedly connected to the top surface of lower mounting bracket 120. Lifting column 320 is fixedly connected to the telescopic end of cylinder 310. Both ends of connecting rod 330 are rotatably connected to the side wall of lifting column 320 and the end of fixed plate 350, respectively. Lower mounting plate 340 is fixedly connected to the bottom of operating platform 100. The middle of connecting rod 330 is slidably connected to lower mounting plate 340. The other end of fixed plate 350 is fixedly connected to arc plate 360. Arc plate 360 ​​is rotatably connected within operating platform 100, fitting the hatch into the mounting area. After entering the slot 110, the starting cylinder 310 drives the lifting column 320 to rise. The lifting column 320 drives one end of the connecting rod 330 to rise, causing the middle of the connecting rod 330 to slide in the lower hanging plate 340. This causes the other end of the connecting rod 330 to fall, driving the fixing plate 350 to move downward. The fixing plate 350 drives the arc plate 360 ​​to rotate into the fitting slot 110, pressing the hatch in the fitting slot 110 tightly. This fixes the hatch when it is cut by the cutting mechanism 200, preventing the hatch from moving and causing deviation in the hole.

[0036] The lower hanging plate 340 has a movable groove 341 in the middle, and the connecting rod 330 has a protrusion 331 fixedly connected in the middle. The protrusion 331 slides in the movable groove 341. When one end of the connecting rod 330 rises, the protrusion 331 in the upper part of the connecting rod 330 slides while rotating in the movable groove 341 in the lower hanging plate 340.

[0037] The top surface of the operating table 100 is provided with a first rotating groove 130, and a first cylinder 131 is fixedly connected in the first rotating groove 130. The end of the arc plate 360 ​​is rotatably connected to the first cylinder 131. The fixed plate 350 drives the arc plate 360 ​​to rotate in the fitting groove 110 on the first cylinder 131.

[0038] The fixed plate 350 has a second rotating groove 351 at its end, and a third cylinder 352 is fixedly connected in the second rotating groove 351. The side plate 321 is fixedly connected to the side wall of the lifting column 320, and the second cylinder 322 is fixedly connected in the middle of the side plate 321. The two ends of the connecting rod 330 are rotatably connected to the second cylinder 322 and the third cylinder 352 respectively. When the lifting column 320 rises, it drives one end of the connecting rod 330 to rotate on the second cylinder 322 and rise with the lifting column 320. The other end of the connecting rod 330 rotates on the third cylinder 352 and descends.

[0039] Working principle: After the hatch is fitted into the fitting groove 110, the cylinder 310 is activated to drive the lifting column 320 to rise. The rise of the lifting column 320 causes one end of the connecting rod 330 to rotate on the second cylinder 322 and rise with the lifting column 320. This causes the upper protrusion 331 of the connecting rod 330 to slide in the movable groove 341 in the lower hanging plate 340 while rotating. This causes the other end of the connecting rod 330 to rotate on the third cylinder 352 and descend. The descent of the other end of the connecting rod 330 causes the fixing plate 350 to move downward. The fixing plate 350 causes the arc plate 360 ​​to rotate on the first cylinder 131 into the fitting groove 110, pressing the hatch in the fitting groove 110 tightly. This fixes the hatch when it is cut by the cutting mechanism 200, preventing the hatch from moving and causing deviation in the hole.

[0040] Please see Figures 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The top support mechanism includes a motor 410, a lead screw 420, a threaded plate 430, an elastic element 440, and a suction cup 450.

[0042] The motor 410 is fixedly connected to the middle of the fitting groove 110, the lead screw 420 is fixedly connected to the power output end of the motor 410, the threaded plate 430 is threadedly connected to the lead screw 420, the two ends of the elastic element 440 are fixedly connected to the top of the fitting groove 110 and the bottom of the threaded plate 430 respectively, and the suction cup 450 is fixedly connected to the top of the threaded plate 430. When the motor 410 is started, the motor 410 drives the lead screw 420 to rotate, the lead screw 420 drives the threaded plate 430 to rise and pull the elastic element 440 up, the threaded plate 430 drives the suction cup 450 to rise and suck up the middle of the hatch, increasing the fixation of the middle of the hatch.

[0043] The elastic element 440 includes a telescopic rod 441 and a spring 442;

[0044] The telescopic rod 441 is fixedly connected at both ends to the top of the fitting groove 110 and the bottom of the threaded plate 430, respectively. The spring 442 is fixedly connected at both ends to the top of the fitting groove 110 and the bottom of the threaded plate 430, respectively. The spring 442 passes through the telescopic rod 441. The threaded plate 430 rises to stretch the telescopic rod 441 and the spring 442.

[0045] The top of the lead screw 420 is fixedly connected to the limiting plate 421. The top of the limiting plate 421 fits against the top of the hatch. The limiting plate 421 prevents the threaded plate 430 from sliding out of the lead screw 420. After the hatch is fitted into the fitting groove 110, the middle contacts the top of the limiting plate 421, supporting the middle of the hatch and preventing the cutting from causing the middle of the hatch to be recessed and causing the hole position to shift.

[0046] Working principle: After the hatch is fitted into the fitting groove 110, the middle of the hatch contacts the top of the limiting plate 421, supporting the middle of the hatch and preventing the hole position from shifting due to the indentation in the middle of the hatch caused by cutting. The motor 410 is started, and the motor 410 drives the lead screw 420 to rotate. The lead screw 420 drives the threaded plate 430 to rise. The rising threaded plate 430 stretches the telescopic rod 441 and the spring 442. The threaded plate 430 drives the suction cup 450 to rise and suck up the middle of the hatch, increasing the fixation of the middle of the hatch. After the cutting is completed, the motor 410 is started to reverse and drive the lead screw 420 to reverse. The lead screw 420 drives the threaded plate 430 to slide down. The threaded plate 430 drives the suction cup 450 to slide down and disengage from the middle of the hatch.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
