Description
Technical Field
The utility model belongs to a grinding and polishing device, concretely relates to novel hand-held type grinding and polishing device.
Background
The rapid development of modern industry puts higher requirements on the surface quality of workpieces, the surface quality not only affects the appearance of the workpieces, but also directly affects the service performance and service life of the workpieces, and the quality of the surface quality is particularly important for dies. In the modern manufacturing industry, the mold manufacturing is of great importance and becomes an important mark of the national industrial level. The mold is a tool for manufacturing parts by a replication method, and in recent years, the mold manufacturing industry has been rapidly developed and is widely used in the machine industry. With the development of science and technology, the market competition at home and abroad is intensified, and the requirements on the die are higher and higher. At present, the surface roughness becomes an important mark for measuring the quality of a mold product, and only if the roughness of the mold surface is low, the roughness of the product processed by the mold surface is also low. Therefore, surface polishing treatment has become an important means for surface processing of some key parts in the mold, engineering machinery, medical equipment and aerospace industries.
The shaping of the surfaces of the mould impressions is now substantially automated. In order to remove the tool mark or hardened layer left on the surface of the mold cavity by mechanical machining or electric discharge machining, the surface of the mold cavity must be subjected to grinding and polishing after the geometric shape machining in order to obtain the required size, shape, positional accuracy and surface roughness. Grinding and polishing are used as an important process for processing the die cavity, the processing time of the grinding and polishing process accounts for 30-50% of the manufacturing time of the whole die, and the cost of the grinding and polishing process accounts for 5-30% of the total manufacturing cost. Lapping and polishing have become a bottleneck in the mold manufacturing process.
Currently, the most common grinding and polishing method is manual grinding and polishing, i.e. an operator uses a handheld grinding and polishing device to perform polishing operation on a mold cavity. The grinding and polishing device is divided into front-back reciprocating movement and left-right reciprocating movement (left-right swing) according to the running track of the grinding shaft, and the grinding and polishing effect can be best by combining the two running tracks.
In a traditional handheld grinding and polishing device, a grinding shaft is generally in transmission connection with a front-back linear motion mechanism and a left-right swinging mechanism, and due to the fact that the length of a transmission shaft in a front-back linear motion structure is relatively long, the front-back linear motion mechanism can swing up and down during front-back linear motion, so that the front-back linear motion mechanism can be reacted back to the front-back linear motion mechanism to cause the front-back linear motion mechanism to swing up and down, and the structure is unstable; the structure of the front-back linear motion and the structure of the left-right swinging motion are connected through a connecting rod, the traditional connecting rod is usually an outwards bent angle-shaped part (as shown in figure 1), the stress point of the connecting rod is at the bending position, the stress point is as high as the front-back linear motion mechanism, and the stability is poor due to the relatively high position; therefore, a novel handheld grinding and polishing device is designed, the stress point of the connecting rod can be lowered, and meanwhile the connecting rod can be connected with the upper structure and the lower structure better.
