Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deburring processing, in particular to a multi-dimensional deburring processing center for pressure casting parts that can be turned over. BACKGROUND

[0002] In modern manufacturing, pressure casting technology is widely used in the fields of automobiles, aerospace, electronics and home appliances due to its high efficiency, high precision and good surface quality. After forming, due to factors such as mold parting surface, ejector pin position and metal liquid flow, burrs, flash and other defects often occur at the edges or holes of the pressure casting parts. These burrs not only affect the assembly accuracy and appearance quality of the parts, but also may cause wear, stress concentration or poor sealing during use. Therefore, the deburring process is an indispensable key link in the post-processing of pressure casting parts. Traditional deburring methods mainly include manual polishing, mechanical cutting, vibration polishing, sand blasting and chemical deburring. Manual polishing relies on the experience and technical level of the operator, although it is highly flexible, but it is low in efficiency, poor in consistency, and difficult to deal with complex geometric burrs;

[0003] In the announcement No. CN110722422A discloses a kind of non-standard aluminum piece automatic inner and outer burr equipment, including non-standard aluminum piece to be processed, still including rack, rotary table, three-jaw chuck, lifting assembly, deburring assembly, electromagnetic overturning assembly and outside clamping assembly, the top of rack is equipped with rotatable circular work platform, three-jaw chuck is horizontally installed at the top of lifting assembly, electromagnetic overturning assembly is vertically arranged at the eccentric place of work platform top, deburring assembly includes deflection mechanism, transverse displacement mechanism and quick rotating grinding head, grinding head is rotatably arranged below deflection mechanism;This non-standard aluminum piece automatic inner and outer burr equipment is simple to operate, and automatic deburring can improve work efficiency and product quality. The inner and outer clamping of non-standard aluminum piece can be realized by three-jaw chuck and outside clamping assembly. The deflection mechanism realizes the adjustment of the angle of grinding head, so as to realize the deburring operation of the outside chamfer;

[0004] The above-mentioned prior art sets multiple clamping assemblies to clamp the workpiece during use, and the workpiece is polished. However, during this process, the workpiece is fixedly arranged and cannot be flexibly turned over, resulting in a single polishing surface. The complex structure of the back surface and side surface of the workpiece, such as the groove, cannot be covered by the deburring device. Therefore, multiple repeated clamping is required to complete the full surface treatment, the deburring efficiency is low, manual turning is required, which is time-consuming and labor-intensive, and the degree of automation is low. Therefore, corresponding improvement is required.

[0005] The application discloses an aluminum die casting deburring equipment, which comprises a bottom plate, a vertical plate fixedly arranged on the upper surface of the bottom plate, a rotating shaft rotatably arranged in the vertical plate, a cylinder fixedly arranged at the end of the rotating shaft, a speed reducer and a driving motor one fixedly arranged on the side wall of the vertical plate, a driving end of the driving motor one connected with the input end of the speed reducer, the output end of the speed reducer connected with the rotating shaft, a cylinder cover sleeved below the cylinder, a handle fixedly arranged on the lower surface of the cylinder cover, and a sealing washer one arranged between the cylinder cover and the cylinder.

[0006] The above prior art is used by putting the aluminum die casting into the cylinder, and rotating the corresponding rotating disc and neodymium magnet to disturb the grinding magnetic needle in the cylinder, so as to realize the polishing and deburring operation of the aluminum die casting. However, the movement speed of the magnetic needle is restricted by the magnetic field strength and the rotating speed. For mass production or thick-walled aluminum die casting (such as wall thickness of more than 5 mm), the single-piece processing time is longer, which is much higher than that of abrasive polishing or robot polishing, and it is difficult to meet the demand of efficient production. In addition, the movement track of the magnetic needle is affected by the magnetic field distribution. If the cylinder structure design is unreasonable (such as too large diameter or irregular shape), the magnetic needle density in the edge area may be lower than that in the center area, resulting in uneven grinding phenomenon on the surface of the aluminum die casting. Therefore, corresponding improvement is needed. SUMMARY
