DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a car door polishing machine for car beautification, comprising a base 1 and a gantry 3, a positioning part 2 is arranged inside the base 1, and the positioning part 2 comprises: a motor 21, a guide rail 22, a screw 23, a screw sleeve 24, a movable platform 25, a fixed platform 26, a short slide 27, a rotating plate 28, a hexagonal groove 29, an abutment block 210, a through hole 211, a short rod 212, a slider 213, a clamping rod 214, a clamping wheel 215, a placement plate 216, a telescopic spring 217, a trigger block 218, a guide groove 219, a reset spring 220, and a support rod 221.

[0024] The motor 21 is fixedly connected to the surface of the base 1, the output shaft of the motor 21 passes through the base 1, and the output shaft of the motor 21 is rotatably connected to the base 1, the output shaft of the motor 21 is fixedly connected with a screw 23, the screw 23 passes through the base 1 and is rotatably connected, the screw 23 passes through and is threadedly connected with a screw sleeve 24, the inner side of the base 1 is fixedly connected with a guide rail 22, the screw sleeve 24 passes through the guide rail 22 and is slidably connected, the top surface of the screw sleeve 24 is fixedly connected with a moving platform 25, and the clamping wheel 215 is made of rubber material and has a certain elasticity, which can effectively alleviate the vibration deviation during processing to a certain extent, start the motor 21, the motor 21 will drive the moving platform 25 and the fixed platform 26 to move through the screw 23 and the screw sleeve 24, so that the gantry 3 can process the car door, the bottom surface of the fixed platform 26 is fixedly connected to the top surface of the moving platform 25, the top surface of the fixed platform 26 is provided with a short slide groove 27, the inner wall of the fixed platform 26 is rotatably connected with a rotating plate 28, and the top surface of the rotating plate 28 is provided with a hexagonal groove 29, The top surface of the rotating plate 28 is fixedly connected with a resistance block 210, and a through hole 211 is opened on the surface of the rotating plate 28. The short rod 212 passes through the hexagonal groove 29, and the short rod 212 is slidably connected to the hexagonal groove 29. The top surface of the short rod 212 is fixedly connected with a slider 213. When the resistance block 210 is resisted and rotated by the trigger block 218, the rotating plate 28 will be driven to rotate together. When the rotating plate 28 rotates, the hexagonal groove 29 will resist the short rod 212, so that the short rod 212 drives the slider 213 to rotate. The top surface of the slider 213 is fixedly connected with a clamping rod 214, and the top of the clamping rod 214 is penetrated and rotatably connected with a clamping wheel 215. When the slider 213 rotates, the clamping rod 214 is driven to rotate together, but the clamping rod 214 is limited by the short slide 27, so that the clamping rod 214 can only slide along the short slide 27, and the return spring 220 is compressed. When the clamping rod 214 slides along the short slide 27 and shrinks toward the middle, it drives the clamping wheel 215 to position the door. The surface of the fixed platform 26 is penetrated with a support rod 221, and the support rod 221 is slidably connected with the fixed platform 26. The support rod 221 penetrates the movable platform 25 and is slidably connected. The top surface of the support rod 221 is fixedly connected with a placement plate 216. When the door to be polished is subjected to cosmetic polishing, the door to be processed is lifted by a lifting device and placed on the placement plate 216, and the gravity of the door itself exerts downward pressure on the placement plate 216. A trigger block 218 is fixedly connected to the bottom surface of the placement plate 216 . A guide groove 219 is provided on the surface of the placement plate 216 . The clamping rod 214 passes through the guide groove 219 , and the clamping rod 214 is slidably connected to the guide groove 219 .A return spring 220 is fixedly connected to the surface of the clamp rod 214, and the return spring 220 is located on the inner side of the short slide groove 27, and the end of the return spring 220 away from the clamp rod 214 is fixedly connected to the inner side of the short slide groove 27. When the car door is processed, the processed car door is pulled up by the lifting equipment, so that the telescopic spring 217 will lift the placement plate 216, and the compressed return spring 220 will push the clamp rod 214 back to its original position. Through the six groups of clamp rods 214 and the clamping wheels 215, car doors of different sizes can be positioned, and the adaptability is wide. The bottom surface of the trigger block 218 is semicircular, and the cross section of the resistance block 210 is triangular. When the placement plate 216 is pressed downward by the gravity of the door, it will move downward through the support rod 221, and will drive the trigger block 218 to move downward together. When the trigger block 218 moves downward, the semicircular bottom surface of the resistance block 210 will gradually resist the inclined surface of the resistance block 210, thereby causing the resistance block 210 to be resisted and rotated. The bottom surface of the rotating plate 28 is in contact with the inner wall of the fixed platform 26, and the top surface of the rotating plate 28 is in contact with the bottom surface of the slider 213. A telescopic spring 217 is fixedly connected between the placement plate 216 and the fixed platform 26, and the support rod 221 passes through the through hole 211.

[0025] Based on the above embodiment, when performing cosmetic polishing on a car door that needs to be polished, the car door that needs to be processed is lifted by a lifting device and placed on the placement plate 216, and the gravity of the car door itself will apply downward pressure to the placement plate 216. When the placement plate 216 is pressed downward by the gravity of the car door, it will move downward through the support rod 221, and will drive the trigger block 218 to move downward together. While the trigger block 218 moves downward, the semicircular arc on the bottom surface of the resistance block 210 will gradually resist the inclined surface of the resistance block 210, thereby causing the resistance block 210 to be resisted and rotated, and while the resistance block 210 is resisted and rotated by the trigger block 218, it will drive the rotating plate 28 to rotate together, and when the rotating plate 28 rotates, the hexagonal groove 29 will resist the short rod 212, so that the short rod 212 drives the sliding The block 213 rotates to a certain extent. When the slider 213 rotates, it will drive the clamping rod 214 to rotate together, but the clamping rod 214 will be limited by the short slide groove 27, so that the clamping rod 214 can only slide along the short slide groove 27, and the return spring 220 will be compressed. When the clamping rod 214 slides along the short slide groove 27 and shrinks to the middle, it will drive the clamping wheel 215 to position the car door, so that the damage caused by vibration to the grinding and polishing equipment on the gantry 3 when polishing and beautifying the car door is reduced. The clamping wheel 215 is made of rubber material and has a certain elasticity. To a certain extent, it can also effectively alleviate the vibration deviation during processing. Start the motor 21, and the motor 21 will drive the movable platform 25 and the fixed platform 26 to move through the screw 23 and the screw sleeve 24, so that the gantry 3 can process the car door.

[0026] When the door is processed, the processed door is pulled up by the lifting equipment, so that the telescopic spring 217 lifts the placement plate 216, and the compressed return spring 220 pushes the clamping rod 214 back to its original position. The six groups of clamping rods 214 and the clamping wheels 215 can be used to position doors of different sizes. It has wide adaptability and does not require the bolts to be constantly disassembled and fixed for processing. It is convenient and efficient.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
