Description

Rotary automatic shovel

The invention relates to a shovel device, in particular to a rotary automatic shovel device which can be easily assembled on a spindle of a CNC machine tool and has high processing precision.

According to the method, the hard track surface is assembled and used after precision shovel processing. The shovel technology mainly removes the rough part of the hard track sliding surface, which improves the precision of the machine. The lubricating oil can be stored in the groove of the shovel (shovel spot), so that the mating surface can be smoothed when it contacts the sliding surface, and the precision life of the hard surface of the hard rail is greatly improved. The greater the damping (the oil in the shovel), the more effective the vibration damping effect is. Good, the greater the dynamic rigidity during processing (the smaller the dynamic elasticity), the higher the precision. Therefore, the shoveling technology is an important step in laying the foundation for the high-precision and high-load hard-rail mobile platform assembly process. The accuracy and reliability of the overall mobile platform industry has a decisive impact. When the shovel is processed, the shovel is mainly carried out by artificial means. It can be divided into two types: artificial shovel and artificial semi-automatic shovel. The main method is the two shovel methods, one is the waist shovel method, which mainly relies on the hand-held shovel handle to lean against the waist, and when it is half-turned, it stands up and advances forward, so that the shovel blade is scraped on the workpiece. For the arm shovel method, the shovel handle is placed on the arm, and the shovel blade is scraped on the workpiece by the instantaneous force, while the artificial semi-automatic shovel is to carry the semi-automatic shovel on the shoulder and start. After the motor, the shovel head makes a rapid back-and-forth reciprocating motion, thereby generating scraping on the workpiece, so as to shovel a small pit on the hard rail track, so as to store lubricating oil in the micro-pits, thereby reducing The wear between the rails provides a high-precision and high-load effect; however, the aforementioned artificial shovel or semi-automatic shovel method can create pits on the track, but there is a manual method of shovel, which must not only rely on long-term Accumulation of experience can produce good quality shovel parts, and artificial shovel technology is difficult to learn and hard and time-consuming, which makes it difficult for talents to develop. The semi-automatic shovel machine with manual clamping is quite cumbersome, so it requires quite good technology. The operation can be carried out, and the difficulty in cultivating this phase technique is relatively increased, and improvements are made.
