Description

Technical Field

[0001] This utility model relates to the field of flipping device technology, specifically a flipping device for processing automobile fenders. Background Technology

[0002] The car fender is the outer body panel that covers the wheels. It is named after the shape and position of this part on the old car body, which resembles a bird's wing. According to the installation position, it is divided into front fender and rear fender. The front fender is installed at the front wheel and must ensure the maximum limit space when the front wheel rotates and bounces. The function of the fender is to prevent sand, gravel and mud kicked up by the wheels from splashing onto the bottom of the car body during the car's operation. Therefore, the materials used must be weather aging resistant and have good formability.

[0003] As disclosed in patent application CN222521106U, a flipping device for processing automobile fenders includes multiple adjustment grooves on the end faces of a first and second adjustment strip. Fasteners are inserted into these grooves to fix the first and second adjustment strips in place. Changing the distance between the first and second adjustment strips adjusts the distance between the first and second clamping frames. The first and second clamping frames are adjusted according to the width of the automobile fender. By adjusting the distance between the first and second clamping frames, the device can adapt to automobile fenders of different widths, thereby meeting different processing requirements.

[0004] Although it enables applications in various scenarios and improves equipment utilization; by precisely adjusting the distance between the clamping frames, the equipment can ensure that the car fender remains stable during processing and avoid displacement or shaking.

[0005] However, this does not solve the problem that existing fender-flipping devices are generally not convenient for easy height adjustment when using them to clamp the car fenders, and are not easy to adjust to adapt to car fenders of different lengths, thus affecting the range of the fender-flipping device's clamping range. Utility Model Content

[0006] The purpose of this utility model is to provide a flipping device for processing automobile fenders, so as to solve the problems mentioned in the background art, such as the inconvenience of adjusting the height of the flipping device to clamp the automobile fender, the inconvenience of adjusting the flipping device to adapt to automobile fenders of different lengths, and the impact on the clamping range of the flipping device on the automobile fender.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flipping device for processing automobile fenders, comprising a traveling frame and a cylinder. The cylinder is mounted on the top of the traveling frame, a push rod is mounted on the output end of the cylinder, and a moving frame is mounted on the bottom end of the push rod. Limiting sleeves are symmetrically mounted on the top of the traveling frame near the cylinder. Limiting rods are slidably mounted inside each limiting sleeve, extending to the outside of the limiting sleeve and connected to the moving frame. Two sets of bidirectional threaded sleeves are slidably mounted inside the moving frame. A front clamping frame is mounted on the bottom end of one bidirectional threaded sleeve, and a rear clamping frame is mounted on the bottom end of the other bidirectional threaded sleeve. A stepper motor is mounted on the outer wall of the rear clamping frame, a rotating shaft is mounted on the output end of the stepper motor, a drive pulley is fitted on the surface of the rotating shaft, and a belt is fitted on the surface of the drive pulley. A drive shaft is movably mounted on the bottom end of the rear clamping frame, extending to the outside of the rear clamping frame.

[0008] Preferably, a driven pulley is fitted onto the surface of the drive shaft, and the belt extends to the surface of the driven pulley. A driven shaft is movably mounted at the bottom end of the front clamping frame, and the driven shaft extends to the outside of the front clamping frame.

[0009] Preferably, a clamping seat is symmetrically installed at one end of the drive shaft and the driven shaft, and a support frame is installed on the outer wall of the clamping seat.

[0010] Preferably, a servo motor is installed on the outer wall of the moving frame near the stepper motor. The output end of the servo motor is equipped with a bidirectional threaded rod, which extends into the interior of the moving frame and is threadedly connected to a bidirectional threaded sleeve.

[0011] Preferably, a first motor is installed at the top of the support frame, and gear rocker arms are symmetrically installed inside the support frame.

[0012] Preferably, the output end of the first motor is equipped with a drive shaft, and the drive shaft is connected to a gear rocker arm, and the top of the gear rocker arm is equipped with a clamping arm.

[0013] Preferably, each of the clamping arms has a drive pin movably installed inside, and the drive pin extends to the outside of the clamping arm and is connected to a gear rocker arm. Each of the clamping arms has a limit arm installed inside, and the limit arm extends to the outside of the clamping arm.

[0014] Preferably, a limiting pin is installed at one end of the limiting arm near the support frame, and the limiting arm is movably connected to the support frame via the limiting pin. A connecting pin is installed at one end of the limiting arm near the clamping arm, and the limiting arm is movably connected to the clamping arm via the connecting pin.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the flipping device not only realizes the convenient height adjustment of the flipping device to clamp the car fender, but also facilitates stable flipping to process the reverse side of the car fender, and facilitates the convenient adjustment of the flipping device to adapt to car fenders of different lengths. In addition, it increases the range of the flipping device for clamping the car fender, and facilitates the convenient and fast clamping of the car fender by the flipping device.

[0016] The cylinder drives the moving frame to move up and down via the push rod. The limiting sleeve slides on the surface of the limiting rod to limit and support the moving frame, making it easy to move the moving frame to a suitable height. The car fender is held by the clamping arms on both sides. The stepper motor drives the rotating shaft to rotate, the rotating shaft drives the driving pulley to rotate, the driving pulley drives the belt to move, the belt drives the driven pulley to rotate, the driven pulley drives the driving shaft to rotate, and the driving shaft drives the clamped car fender to flip over. This facilitates the flipping of the car fender and realizes convenient height adjustment of the flipping device to clamp the car fender. It also facilitates stable flipping for processing the reverse side of the car fender, improving the convenience of processing and flipping the car fender.

[0017] The servo motor drives the bidirectional threaded rod to rotate, which in turn drives the bidirectional threaded sleeve to move. The two sets of bidirectional threaded sleeves drive the front clamping frame and the rear clamping frame to move inward, which facilitates clamping of car fenders of different lengths. This enables the flipping device to be easily adjusted to adapt to car fenders of different lengths, and increases the range of car fender clamping by the flipping device.

[0018] The first motor drives the drive shaft to rotate, which in turn drives the gear rocker arm to rotate. The gear rocker arm, via the drive pin, drives the clamping arm to move inward. Supported by the limit pin, the limit arm, via the connecting pin, limits and supports the clamping arm, making it easier for the clamping arm to hold the car fender. This enables the flipping device to hold the car fender quickly and easily, improving the convenience of the flipping device in holding the car fender. Attached Figure Description
