Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum part grinding, and more specifically to a grinding device for aluminum die-castings. Background Art
[0002] The painting of aluminum parts has a direct impact on the appearance of the product. However, there is a very important process after painting, that is, polishing and grinding. As we all know, after the raw material aluminum plate comes in, through a series of processes such as scribing and chamfering, the surface will definitely be damaged and burrs will be left at the edges. If not ground, it will directly affect the quality of the product. The polishing of aluminum single plates is a technical issue. Qualified aluminum single plate manufacturers will never allow these burrs. Therefore, polishing and grinding is a necessary process. Therefore, each aluminum part must be ground after painting, and the surface must be smooth, so that there will be no concavities and convexities on the surface of the plate, nor will it affect the appearance.
[0003] Deficiencies of the prior art: At present, there are still many factories that grind aluminum parts by manually holding the objects on a grinding machine for polishing. Such an operation is relatively dangerous and easy to hurt the hands for unskilled employees. By holding the aluminum parts and grinding them on the grinding wheel, for the control of some angles, inexperienced personnel are not steady when holding and are very likely to grind the aluminum parts to scrap.
[0004] When the staff holds the aluminum parts to work, the rotating speed of the grinding wheel is very fast. The contact friction between the aluminum parts and the grinding wheel will generate a large amount of aluminum chips. Driven by the high-speed rotation of the grinding wheel, these aluminum chips will be driven to fly everywhere, and it is easy for these aluminum chips to splash into the eyes of the staff, which will cause physical harm to the employees. Content of the Utility Model
[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a grinding device for aluminum die-castings to solve the problems existing in the above-mentioned background art.
[0006] To achieve the above object, the utility model provides the following technical solution: A grinding device for aluminum die-castings, including a workbench. A motor is threadedly connected to the side of the inner cavity of the workbench. A bevel gear is fixedly connected to the top of the motor. A rotating shaft is meshed with the outer edge of the bevel gear. A retaining pin is clamped on the outer edge of the outer circle of the rotating shaft. A rotary bearing is movably sleeved on the outer edge of the outer circle of the rotating shaft. A grinding disc is movably sleeved on the side of the rotating shaft. A fixed column is movably sleeved on the outer edge of the outer circle of the rotary bearing. A lighting lamp is placed on the top of the workbench. Under the rotation of the motor, the bevel gear and the transmission shaft are meshed with each other to realize the mutual transmission between the gears, thereby driving the grinding disc connected to the transmission shaft. The retaining pin clamped on the rotating shaft is used for convenient and quick fixing and disassembly of the grinding disc.
[0007] Furthermore, a housing is threadedly connected to the top of the workbench. Shrinkage plates are fixedly connected to both sides of the housing. A sliding button is movably connected to the side of the shrinkage plate, and the sliding button slides in an arc in the chute of the shrinkage plate.
[0008] Furthermore, a transparent eye protection plate is fixedly connected to the side of the sliding button. A hand-held handle is fixedly connected to the side of the transparent eye protection plate. The transparent eye protection plate slides in the shrinkage plate through the connected sliding button, achieving the function of free contraction.
[0009] Furthermore, a moving plate is placed on the top of the workbench. Threaded holes are opened on the top of the moving plate. A threaded bolt is threadedly connected to the inner wall of the threaded hole. The opened threaded hole and the threaded bolt are for facilitating the disassembly, replacement, and maintenance of the structure inside the moving plate.
[0010] Furthermore, a slider is threadedly connected to the side of the threaded bolt. A threaded rod is movably connected inside the slider. An operation disk is fixedly connected to the side of the threaded rod. A slide rail is movably connected inside the slider.
[0011] Furthermore, an angle adjuster is threadedly connected to the top of the moving plate. A rotation control disk is movably connected to the side of the angle adjuster. A firmware hole is opened at the bottom of the angle adjuster. A clamp is fixedly connected to the top of the angle adjuster.
[0012] Technical effects and advantages of the present utility model:
[0013] 1.

Moreover, the transparent eye protection plate can perform free contraction operations in the chute of the shrinkage plate through the fixedly installed sliding button.
[0014] 2. By providing a clamp, the present utility model is beneficial for fixing the aluminum parts well, eliminating the need for manual holding, and avoiding accidental injuries caused by operation mistakes. Additionally, through the angle adjuster fixed at the bottom of the clamp, angle adjustment can be completed, which is beneficial for more precise angle grinding and polishing of the aluminum parts.
[0015] 3. Through the threaded holes and threaded bolts provided on the moving plate, the present utility model is beneficial for cleaning the excessive aluminum chips accumulated inside the bottom of the moving plate after long-term use. It can be disassembled for regular cleaning or regularly oiled for internal maintenance to prevent jamming during the use of the moving plate. Through the combined use of the clamp, angle adjuster, and moving plate, the phenomenon of accidental injury caused by employees holding aluminum parts for grinding is avoided.
