Reciprocating automatic shovel device

The invention relates to a shovel device, in particular to a reciprocating automatic shovel device with a compact structure, convenient assembly and rapid automatic shovel.

According to the current hard track of the machine tool, a shovel process is required before assembly. The shoveling technology mainly removes the rough part of the hard track sliding surface, so that the precision of the machine is improved and the shovel groove is The shovel spot and the oil bag can store lubricating oil, so as to reduce the friction and wear, so that the mating surface can be smoothed when sliding, and the precision life of the hard rail sliding surface is greatly improved. Therefore, the shoveling technology is high-precision and high-load. The important steps in laying the foundation for the hard-track mobile platform assembly process, and have a decisive impact on the accuracy and reliability of the overall mobile platform industry; In the case of shovel treatment, the shovel is mainly processed by hand. In operation, the shovel is held by hand and held in a half-twist or horse-step position by the waist and arm force. The method of cutting the knife, the scraping effect of the scraping on the workpiece to be processed, and then scooping out a small pit on the workpiece to be processed, which can be used to store lubricating oil, thereby reducing friction And it provides a high-precision and high-load effect. Moreover, since the machine tool is exposed to the external metal surface, it is easy to collide or rub against other external objects, and over time, many scars will be generated on the metal surface of the machine tool. In addition to the accuracy and longevity of the machine tool, the shovel technology can also provide a beautiful tool machine by scooping out a fixed flower shape that can fill the metal surface of the machine tool. However, the common point of the above-mentioned shovel processing is that it needs to be manually The shovel processing needs to rely on the long-term experience of the shovel staff. In addition, due to the influence of the product and the processing environment, it must be bent and half-turned for a long time. Therefore, the operation is quite uncomfortable, artificial. Shovel technology is not only difficult to learn, but also difficult and time-consuming, which makes it difficult for talents to develop. The semi-automatic shovel machine with manual clamping itself is quite cumbersome and requires a fairly good technique to operate, which increases the difficulty of cultivating this phase technology. Moreover, each shovel staff has different standards for determining the processing quality of the workpiece, and it is relatively incapable of effectively controlling the processing quality of the shovel flower.

Therefore, the present inventors have in view of the existing artificial shovel method, which not only requires long-term experience accumulation to maintain the quality of the shovel, the shovel technique is difficult to learn, and the insufficiency and problems of the quality of the shovel processing cannot be effectively controlled. Research and experimentation has finally led to the development of a invention that improves both existing defects.
