Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, and in particular to a non-marking spray coating fixture for aluminum chassis. Background Technology

[0002] Aluminum chassis, primarily made of aluminum alloy, are widely used in various fields. Surface treatment is crucial to both appearance and performance. Spraying is a common treatment method. The non-marking spraying fixture uses a specially designed clamping structure to contact non-critical areas of the chassis, employing soft and wear-resistant contact materials to avoid direct hard contact between the fixture and the workpiece surface during the spraying process. This ensures stable positioning of the chassis during the spraying process, guaranteeing uniform coating coverage without contact marks, thus improving product appearance quality and yield.

[0003] Traditional aluminum chassis non-marking spraying fixtures fix the workpiece with simple mechanical clamps and support structures, using rubber and soft materials as contact buffers to reduce direct friction and avoid scratches. At the same time, they rely on manual adjustment of the fixture position to adapt to chassis of different sizes to ensure workpiece stability during spraying. However, these fixtures have the problem that the contact materials easily absorb paint, and after long-term use, hard spots will form due to paint accumulation.

[0004] Current aluminum chassis non-marking spraying fixtures achieve high-precision spraying through material innovation and intelligent design. Based on an adaptive positioning structure, they automatically match the chassis size through pneumatic and hydraulic clamps, and reduce scratches caused by physical friction by combining low-friction material contact points. The fixture structure uses finite element analysis to optimize the distribution of support points, disperse gravity and clamping force, and prevent indentations caused by local deformation. It intelligently adjusts the spraying path to cover complex curved surfaces and avoids the blind spots of traditional fixtures. However, there are still problems such as the need for modular design for rapid changeover of multi-model compatible fixtures, and the need for manual calibration when switching between different specifications of chassis, which is time-consuming and affects production efficiency. To address these issues, a non-marking spraying fixture for aluminum chassis is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a seamless aluminum chassis spraying fixture designed to improve the problem of manual calibration required when switching between different chassis specifications in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a traceless spraying fixture for aluminum chassis, comprising a frame and a clamping block, wherein a fixing frame is fixedly connected to the inner wall of the frame, an adaptive mechanism is provided on the outer wall of the fixing frame, a fixing column is fixedly connected to the outer wall of the clamping block, and a cleaning mechanism is provided on the top of the clamping block. The adaptive mechanism includes a base, the outer wall of which is fixedly connected to the outer wall of a fixed frame, a second motor fixedly connected to the inner wall of the base, a turntable rotatably connected to the outer wall of the second motor, a spring fixedly connected to the outer wall of the clamping block, a lifting assembly provided on the outer wall of the fixed frame, and a telescopic assembly provided on the inner wall of the turntable.

[0007] As a further description of the above technical solution: The cleaning mechanism includes a second pressure plate, the bottom of the outer wall of the second pressure plate is fixedly connected to the top of the outer wall of the clamping block, a second air pump is fixedly connected to the outer wall of the second pressure plate, and a rotating component is provided on the outer wall of the second pressure plate.

[0008] As a further description of the above technical solution: The lifting assembly includes a track, the outer wall of which is fixedly connected to the outer wall of the frame. A first gear is meshed with the outer wall of the track, and a second gear is meshed with the outer wall of the track. A first motor is rotatably connected to the outer wall of the second gear.

[0009] As a further description of the above technical solution: The telescopic assembly includes a first cylinder, the outer wall of which is fixedly connected to the inner wall of the turntable, a first pressure plate is fixedly connected to the top of the outer wall of the first cylinder, and a telescopic shaft is fixedly connected to the outer wall of the first pressure plate.

[0010] As a further description of the above technical solution: The rotating assembly includes a telescopic column, the outer wall of which is fixedly connected to the outer wall of the second pressure plate, the inner wall of which is meshed with a third gear, the outer wall of which is fixedly connected to a transmission block, and the outer wall of which is fixedly connected to a cleaning block.

[0011] As a further description of the above technical solution: A rotating column is fixedly connected to the outer wall of the frame, and a turntable is rotatably connected to the outer wall of the rotating column.

[0012] As a further description of the above technical solution: The outer wall of the frame is fixedly connected to a slide rail, and the outer wall of the slide rail is slidably connected to a slider.

[0013] As a further description of the above technical solution: The outer wall of the slider is fixedly connected to a spray nozzle, and the outer wall of the frame is provided with a groove.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a spring is provided on the fixed column to provide elastic support for clamping different chassis. At the same time, a telescopic shaft is connected to the clamping block, which can adapt to different specifications of chassis by telescopic extension. A second motor is installed on the outside of the turntable to provide power for the clamping chassis to rotate. In order to ensure that the clamped chassis has enough space to rotate during the rotation, the motor drives the gear to rotate, thereby realizing the up and down movement of the fixed frame. While being able to clamp different specifications of chassis, it can also realize automatic spraying of the chassis at various angles.

[0015] In this invention, the telescopic column's telescopic movement causes the internal gear to rotate, which in turn drives the third gear to rotate. This causes the transmission block connected to the third gear to rotate, and simultaneously causes the cleaning block connected to the transmission block to rotate on the surface of the clamping block. The rotation of the cleaning block cleans the paint covering the clamping block, preventing paint buildup from affecting the spraying effect. Attached Figure Description
