Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing, specifically to a brushing device for curved aluminum alloy handles. Background Technology

[0002] High-end home appliances often use aluminum profiles to make handles or frames, giving them a metallic and premium feel. Aluminum alloy handles are formed by bending aluminum profiles to a specific curvature. The radius of curvature of the handle can be arbitrarily designed, achieved through forming processes such as roll bending or pressure bending. In the subsequent brushing process on the handle surface, brushing the curved surface of handles is difficult using conventional straight-bar brushing machines in a streamlined process due to their high curvature. Therefore, it can only be processed manually, which is not only inefficient but also results in inconsistent brushing quality. Summary of the Invention

[0003] This utility model provides a brushing device for curved aluminum alloy handles, which can be used to automatically brush the outer arc surface of aluminum profile handle workpieces with curved curvature; it changes the current situation where curved handle workpieces need to be brushed manually, and has the advantages of stable clamping, reciprocating brushing, uniform brushing pattern, and adjustable brushing roughness and depth.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A brushing device for curved aluminum alloy handles includes a brushing motor mounted on one side of the frame, a brush wheel mounted on the shaft of the brushing motor, a turntable on the upper end face of the frame, a clamping fixture on the turntable to clamp the workpiece, the outer arc surface of the workpiece contacting the brush wheel to brush the texture, and a rotary motor connected to the bottom of the turntable via a shaft.

[0005] During the brushing process, the turntable holds the workpiece and is driven to rotate by a rotary motor. The direction of the rotational linear velocity of the brush wheel is opposite to the direction of rotation of the turntable. Each time the workpiece passes over the surface of the brush wheel, the brush wheel scrapes its surface to form brush patterns.

[0006] The brush motor is mounted on the reciprocating base plate, which is slidably connected to the vertical slide rail via a slider. The vertical slide rail is fixedly mounted on the side of the frame. The lower part of the reciprocating base plate is connected to the upper end of the push rod via a universal ball joint. The lower end of the push rod is connected to the eccentric shaft via a universal ball joint. The eccentric shaft is driven to rotate by the reciprocating motor via a gearbox.

[0007] The reciprocating mechanism described above is driven by a reciprocating motor that rotates an eccentric shaft. The eccentric shaft drives a push rod to reciprocate vertically up and down, which in turn drives the reciprocating base plate to reciprocate vertically up and down, ultimately creating the effect of rapid reciprocating motion of the brush wheel. This rapid reciprocating motion of the brush wheel, scraping the outer arc surface of the workpiece, combined with the brush wheel's own rapid rotation, results in a more uniform texture on the workpiece surface. This avoids the problem of the brush wheel repeatedly scraping the same surface of the workpiece at the same horizontal level, which would otherwise cause uneven brush marks.

[0008] The clamping fixture includes a longitudinally telescopic push-pull cylinder. The piston rod end of the push-pull cylinder is fixedly connected to the cylinder body of the double-outlet cylinder. Clamps are respectively installed on the piston rod ends on both sides of the double-outlet cylinder. The ends of the clamps match the shapes of the two ends of the workpiece. A supporting arc-shaped block is also provided on the inner side of the workpiece's arc surface. Several pressing heads are provided above the workpiece. The pressing heads are installed on the piston rod ends of the rotary cylinder. The rotary cylinder is installed on a turntable.

[0009] The clamping fixture includes two sets of inclined cylinders. Clamps are installed at the piston rod ends of the inclined cylinders, and the ends of the clamps match the shapes of the two ends of the workpiece. Supporting arc blocks are also provided on the inner side of the workpiece's arc surface. Several pressing heads are provided above the workpiece. The pressing heads are installed at the piston rod ends of the rotary cylinders, which are mounted on a turntable.

[0010] To securely fix the curved workpiece on the turntable, the clamping fixture has two structural methods: one is a push-pull cylinder + double-outlet cylinder structure; the piston rod of the double-outlet cylinder retracts, the end of the clamp hooks and presses the two ends of the workpiece, and then the piston rod of the push-pull cylinder retracts, pulling the workpiece back as a whole, so that the inner arc surface of the workpiece is close to the supporting arc block, thus the workpiece is stably clamped and will not be misaligned or loosened during the continuous rotation of the brushing process, ensuring the stability of the brushing process.

[0011] Another clamping fixture structure replaces the push-pull cylinder + double-outlet cylinder with a slanted-pull cylinder, directly mounting the clamps to the piston rod end of the slanted-pull cylinder. This structure is simpler and allows for the installation of multiple clamping devices on the turntable, simultaneously clamping multiple workpieces.

[0012] The middle part of the rotating shaft is connected to the adjustment base plate through a bearing. The adjustment base plate is slidably connected to the horizontal slide rail through a slider. The horizontal slide rail is mounted on the frame. A screw block is also installed at the bottom of the adjustment base plate. The screw hole of the screw block is engaged with the screw rod. Both ends of the screw rod are mounted on the frame through bearings. The rear end of the screw rod is driven to rotate by the adjustment motor through a reduction gearbox.

[0013] Since brush wheels wear down after a period of use, when this happens, the turntable is finely fed to keep it close to the brush wheel surface. This maintains constant pressure between the workpiece and the brush wheel, thus ensuring consistent brush patterns. A servo motor is used for adjustment; the motor drives a lead screw to rotate, which in turn drives the turntable forward, pressing the workpiece against the brush wheel. The motor's feed can be controlled manually by jogging or by using an automatic program.

[0014] The brush wheel is covered with a dust collection hood, which is connected to a dust collection fan via a suction pipe. Dust and debris generated by the brush strokes are sucked away through the suction pipe to prevent environmental pollution and harm to workers' health.

[0015] Advantages of this utility model:

[0016] 1. This utility model is applicable to brushing the outer arc surface of aluminum profile handle workpieces with curved curvature, which changes the current situation where curved handle workpieces need to be brushed manually. The worker only needs to place the workpiece on the fixture and clamp it, start the machine, and the workpiece can be automatically brushed. When the brushing is completed, the equipment will automatically stop and the fixture will be released, thus achieving the effect of automatic brushing.

[0017] 2. This utility model can achieve reciprocating brush texture, and the brush texture surface has a uniform gloss.

[0018] 3. This utility model has an automatic tooling feeding function. After the brush wheel wears, the wear can be compensated by the tooling feeding to achieve a uniform brush pattern.
