Description

Technical Field

[0001] The present application relates to the technical field of aluminum alloy processing, and specifically discloses an aluminum alloy surface treatment and polishing device. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, people's requirements for aluminum alloy castings are getting higher and higher. On the basis of ensuring the lightweight, high strength and high precision of die-castings, people begin to pursue the appearance of die-castings. Among them, electrostatic spraying is a more commonly used surface treatment for aluminum alloy die-castings. Electrostatic spraying technology can ensure that the coating forms a uniform and consistent covering layer on the surface of the casting, and can also ensure good coating effects on different surface shapes and materials. In addition, electrostatic spraying can form a strong surface coating with high corrosion resistance, good durability and enhanced capabilities. As an easily oxidized material, aluminum alloy can be effectively increased by electrostatic spraying for its surface antioxidant and corrosion resistance. Moreover, compared with other surface treatment methods, such as mechanical processing or chemical treatment, electrostatic spraying on the surface of aluminum alloy castings can effectively reduce subsequent operating costs and processing time, thereby improving production efficiency.

[0003] After the aluminum alloy castings are shot blasted and electrostatically powder-coated, the surface of the aluminum alloy castings needs to be polished to obtain a glossier surface. The traditional polishing method is to move the aluminum alloy castings through a conveying mechanism, and at the same time use a sanding belt to contact and rub the surface of the aluminum alloy castings, thereby achieving a polishing effect on the surface of the aluminum alloy castings. However, the commonly used conveying mechanisms are usually conveyor belts or conveyor chains. Due to the gravity of the aluminum alloy castings themselves, the conveying mechanism is prone to bend downward, resulting in a gap between the surface of the aluminum alloy castings and the sanding belt, which affects the polishing effect. Therefore, in view of this, the inventor provides an aluminum alloy surface treatment polishing device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the traditional grinding process of aluminum alloy castings, the conveyor belt or conveyor chain is easily bent downward due to the gravity of the aluminum alloy casting itself, resulting in a gap between the surface of the aluminum alloy casting and the sanding belt, thereby affecting the grinding effect.

[0005] In order to achieve the above-mentioned object, the basic scheme of the present utility model provides an aluminum alloy surface treatment and polishing device, comprising a chassis, a conveying mechanism provided on the chassis, a carrier plate driven by the conveying mechanism and used for mounting aluminum alloy castings, an adjustment component for adjusting the vertical position of the carrier plate, and a polishing mechanism provided on the chassis and polishing the aluminum alloy components on the carrier plate;

[0006] The adjustment assembly includes a fixed plate arranged on the chassis and a number of guide rods vertically slidably connected to the fixed plate. The tops of the guide rods pass through the top of the fixed plate and are provided with limit blocks abutting against the bottom of the carrier plate. Reset springs are provided between the limit blocks and the upper surface of the fixed plate.

[0007] The principles and effects of this basic solution are:

[0008] Compared with the prior art, the utility model provides structures such as a guide rod, a limit block and a return spring, and utilizes the elastic potential energy of the return spring to enable the limit block on the top of the guide rod to squeeze the carrier plate, so that the aluminum alloy casting on the carrier plate can fit tightly with the grinding mechanism, thereby solving the problem in the traditional grinding process of aluminum alloy castings that the conveyor belt or conveyor chain is easily bent downward due to the self-gravity of the aluminum alloy casting, resulting in a gap between the surface of the aluminum alloy casting and the sanding belt, thereby affecting the grinding effect.

[0009] Furthermore, the polishing mechanism includes mounting brackets symmetrically disposed on the top of the chassis, rollers rotatably connected between the mounting brackets, a drive assembly for driving the rollers, and sandpaper disposed on the outer walls of the rollers. The fixing plate is disposed between the mounting brackets. The drive assembly drives the rollers to rotate, causing the sandpaper to rotate along the surface of the aluminum alloy casting and rub against each other, thereby polishing the surface of the aluminum alloy casting.

[0010] Furthermore, the mounting brackets are each vertically slidably connected to mounting plates, the rollers are rotatably connected between adjacent mounting plates, and an adjustment handle is rotatably connected to the mounting brackets, the bottom of which is threadedly connected to the top of the mounting plate. This arrangement allows the height of the rollers and sandpaper to be adjusted as needed, facilitating the grinding of aluminum alloy castings of varying thicknesses.

[0011] Furthermore, the mounting frame is symmetrically provided with slide rails slidably connected to the side walls of the mounting plate. The slide rails limit and guide the sliding of the mounting plate, thereby preventing the position of the mounting plate from being offset.

[0012] Furthermore, a limiting sleeve is provided on the side wall of the adjustment handle and is rotatably connected to the mounting bracket, and a rotation groove is provided on the mounting bracket to match the limiting sleeve. The limiting sleeve and the rotation groove cooperate with each other to limit and guide the rotation of the adjustment handle.

[0013] Furthermore, a guide block is provided at the bottom of the carrier plate, corresponding to the position of the guide rod, and a sidewall of the guide block is provided with an inclined surface that mates with the top of the guide rod. The arrangement of the guide block and its inclined surface facilitates a close fit between the stop block at the top of the guide rod and the guide block, thereby exerting a squeezing effect on the carrier plate.

[0014] Furthermore, an anti-falling protrusion is provided at the bottom of the guide rod passing through the lower surface of the fixing plate to prevent the guide rod from falling off from the fixing plate. BRIEF DESCRIPTION OF THE DRAWINGS

The grinding mechanism includes a mounting frame 6 symmetrically arranged on the top of the chassis 1, a roller 7 rotatably connected between the mounting frames 6, a driving component for driving the roller 7 to rotate, and sandpaper arranged on the outer wall of the roller 7. The driving component includes a grinding motor 5, a transmission belt arranged between the output shaft of the grinding motor 5 and the roller 7, and a pulley and a tensioning pulley for tensioning the transmission belt.

[0024] like Figure 2 As shown, the mounting frames 6 are vertically slidably connected to the mounting plates 9, the rollers 7 are rotatably connected between adjacent mounting plates 9, and the mounting frames 6 are rotatably connected to the adjusting handles 8.
