Description

Technical Field

[0001] The utility model belongs to the technical field of grinding, and in particular relates to a grinding device for an aluminum alloy casing. Background Art

[0002] Aluminum alloy is a light metal material, which is an alloy with a certain amount of other alloying elements added to aluminum. In addition to the general properties of aluminum, it also has specific properties brought by the addition of different alloying elements. Aluminum alloy has high strength, good casting performance and plastic processing performance, as well as good electrical and thermal conductivity, corrosion resistance and weldability. In addition, aluminum alloy also has good ductility and can be made into various aluminum foils, aluminum wires and aluminum strips.

[0003] At present, a common method is to grind by hand using a handheld grinding device. This method not only has high labor intensity, but also is difficult to control the grinding quality, resulting in low grinding efficiency. In addition, debris will splash during the grinding process, which can easily affect the physical and mental health of the workers. Utility Model Content

[0004] The utility model aims to provide a grinding device for an aluminum alloy casing to solve the problems of grinding efficiency and debris splashing in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The purpose of the utility model is to provide a grinding device for an aluminum alloy casing, comprising an arc-shaped plate, a positioning sleeve being fixedly connected inside the arc-shaped plate, and a driven tooth being rotatably connected on one side of the positioning sleeve; sliding aids are symmetrically provided on both sides of the driven tooth, and the sliding aids reduce the wear caused by the rotation of the driven tooth; a power output mechanism is installed on one side of the driven tooth, and the power output mechanism is used to drive the driven tooth to rotate; a plurality of step grooves are equidistantly distributed on the inner wall of the driven tooth, and a cleaning block is installed in the step groove.

[0007] Furthermore, a support leg is fixed to the bottom of the arc-shaped plate, a base is installed below the support leg, a support plate is fixedly connected to the side of the base, and a power output mechanism is installed on the surface of the support plate.

[0008] Furthermore, the power output mechanism includes a motor, and the power output end of the motor is connected to a driving tooth, wherein the driving tooth and the driven tooth mesh with each other. By starting the motor to rotate the driving tooth, the driven tooth rotates synchronously with the meshing of the driving tooth, that is, the driven tooth automatically generates a rotational motion.

[0009] Furthermore, a support frame is installed on one side of the base, and a protective shell is installed on the side of the support frame. The combination of the protective shell and the support frame wraps the power output mechanism and the driven gear, which can prevent external dust from entering the device. The protective shell and the support frame can also isolate and reduce these noises and vibrations to a certain extent, thereby improving the comfort of the working environment.

[0010] Furthermore, the sliding aid includes a positioning tube and a ball. The positioning tube is symmetrically arranged on the outer wall of the driven tooth. The ball is rollingly mounted on the outer wall of the positioning tube. The inner wall of the positioning sleeve is provided with a track groove. The positioning sleeve is arranged on the outer side of the positioning tube and the ball fits in the track groove. The ball slides on the track groove through a precise rolling mechanism to achieve smooth and high-precision movement. This mechanism effectively reduces friction and wear and improves movement accuracy and stability.

[0011] Furthermore, a countersunk hole is passed through the center of the cleaning block, a brush is provided on the surface of the cleaning block, and the outer structure of the cleaning block matches the stepped groove. A positioning hole is provided in the center of the stepped groove, and the cleaning block is installed in the stepped groove so that the positioning hole and the countersunk hole are kept concentric. The bolt passes through the countersunk hole and enters the positioning hole, and the bolt is rotated so that the bolt is fastened inside the positioning hole. In this way, the cleaning block can be easily disassembled, so that the staff can replace and install the cleaning block with different brushes.

[0012] Furthermore, an air duct is installed on the side of the positioning sleeve, and the air duct is connected to the fan system, and the dust and debris generated by grinding inside the driven gear are extracted by the fan, so that the debris can be directly recovered.

[0013] The technical solution of the utility model has the following beneficial effects:

[0014] 1. The positioning sleeves installed on both sides of the positioning tube can position the driven gear in the middle. Combined with the cooperation between the ball and the track groove, the driven gear can rotate smoothly. A detachable cleaning block is used to polish the outer surface of the aluminum alloy casing with a brush under the rotation of the driven gear. The outer surface of the casing can be polished in all directions to improve the polishing efficiency.

[0015] 2. When the driven gear rotates, the grinding dust will be blocked by the positioning sleeve and the driven gear, and the grinding debris will not be splashed. An air duct is installed at one end of the positioning sleeve, and the air duct is connected to the fan system. The dust and debris generated by the grinding inside the driven gear are extracted by the fan, and the debris can be directly recovered without the need for subsequent staff to clean the equipment.
