Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal processing, in particular to a polishing device for special-shaped nonferrous metal casting. Background Art

[0002] Polishing of special-shaped non-ferrous metal castings is a complex and delicate process. Due to their irregular shapes and uneven surfaces, specific polishing methods and techniques are required. Currently, the polishing methods for special-shaped non-ferrous metals include: manual polishing, vibration polishing and CNC polishing.

[0003] Currently, there are two methods for polishing irregular non-ferrous metal castings: manual polishing and CNC polishing machines. Manual polishing is inefficient, has high labor costs, and is not suitable for mass production. CNC polishing machines are expensive and highly technical. Currently, vibration polishing is mostly used for irregular non-ferrous metal castings. The principle is to use a vibration grinder, place the irregular non-ferrous metal casting in the grinder, add abrasive materials, and use friction to smooth the surface. The upper and lower eccentric blocks on the vibration motor will move in coordination with each other, causing the casting to produce a regular rotation and tumbling friction motion, thereby achieving a polishing effect. However, in actual applications, because the casting needs to be placed directly in the grinder, the casting will inevitably collide with the inner wall of the grinder during rotation and tumbling, which can easily cause damage.

[0004] Therefore, the above technical problems need to be solved. Utility Model Content

[0005] The utility model aims to solve the above problems existing in the numerical control polishing machines of the prior art and provides a polishing device for special-shaped nonferrous metal castings which is easy to use and can effectively prevent metal castings from being damaged by collision during polishing.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the present invention is a polishing equipment for special-shaped non-ferrous metal casting, including a centrifugal box and a box cover, the box cover covers the opening installed on the top of the centrifugal box and encloses a receiving cavity for hoisting special-shaped non-ferrous metal casting workpieces, the centrifugal box includes a driving mechanism and a rotating barrel for holding abrasives, the rotating barrel is assembled in the driving mechanism, the box cover includes a cover plate and a protrusion arranged at the bottom of the cover plate and buckled with the top of the driving mechanism, and a material guide cover fixedly installed at the bottom of the protrusion, the interior of the material guide cover is a curved flared structure, and the outer wall of the material guide cover is movably fitted with the inner wall of the rotating barrel.

[0007] Preferably, the drive mechanism comprises a base and a housing enclosing the top opening thereof, and a servo motor fixedly mounted to the bottom of the housing. A control panel enclosing the servo motor is fixedly mounted on the inner bottom wall of the base, and a switch is mounted through an outer side wall of the base. The control panel is electrically connected to the control panel and the switch, respectively. The output end of the servo motor is coaxially fixedly connected to a shaft for mounting the rotary drum. The drive mechanism utilizes the servo motor to achieve the rotary drum's rotational function, and the housing simultaneously provides structural support for the lid.

[0008] Preferably, a conical platform recessed inwardly is provided in the middle of the bottom wall of the rotary drum, and a support seat adapted for the conical platform is provided in the middle of the inner bottom wall of the housing. The conical platform facilitates the rotation and tumbling of the abrasive during the rotation of the rotary drum, leveraging centrifugal force and the material guide shield, thereby further optimizing polishing efficiency.

[0009] Preferably, the shaft sequentially passes through the housing, the support seat, and the conical platform, extending into the rotary barrel and being fixedly connected to the conical platform. The top end of the shaft is covered with an end gland fixedly mounted on the top of the conical platform. The end gland, which covers the top of the conical platform, not only ensures the sealing between the shaft and the rotating assembly, but also helps the abrasive to move toward the periphery under the action of centrifugal force.

[0010] Preferably, a threaded sleeve for assembling a sling is vertically mounted at the center of the raised bottom. The threaded sleeve is primarily used for positioning and assembling the sling. For example, a steel wire can be wound around the head of a screw. When the operator screws the screw thread into the threaded sleeve, the head of the screw and the bottom of the threaded sleeve effectively position the coiled steel wire. Special-shaped non-ferrous metal castings can be tied to the bottom end of the steel wire for slinging.

[0011] Therefore, the utility model has the following beneficial effects: by providing a centrifugal box for containing abrasives and a box cover for hoisting special-shaped non-ferrous metal castings, after the box cover is buckled on the top of the centrifugal box, in conjunction with the driving mechanism, the rotary barrel can cooperate with the material guide cover to form a grinding chamber for the abrasive to rotate and tumble, and with the help of the abrasive, the special-shaped non-ferrous metal castings can be polished, avoiding collisions with the special-shaped non-ferrous metal castings while ensuring their surface treatment effect.
