Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a device for drilling holes on an upper beam of an inner plate of a column. Background Art

[0002] The upper beam of the inner plate of the pillar is one of the important components of the car. During the production process of the upper beam of the inner plate of the pillar, it is necessary to drill holes in the upper beam of the inner plate of the pillar. At present, when punching the upper beam of the inner plate of the pillar, in order to prevent the upper beam of the inner plate of the pillar from shifting, the upper beam of the inner plate of the pillar will be fixed first, and then the upper beam of the inner plate of the pillar will be removed after the punching is completed. The staff needs to continuously install and remove it, which is not only inefficient but also consumes a lot of labor.

[0003] A Chinese patent discloses a drilling device for the upper side beam of the inner plate of the B-pillar of an automobile (authorization announcement number CN215315034U). The patented technology can drive the limit plate to move downward by moving the output end of the hydraulic cylinder downward, and the limit plate can drive the slide plate to move downward on the guide column by moving downward, so that the slide plate is tightly pressed on the surface of the upper side beam of the inner plate of the B-pillar, thereby preventing the upper side beam of the inner plate of the B-pillar from loosening during punching, affecting the punching efficiency, and after the punching is completed, the output end of the hydraulic cylinder is reset, so that the slide plate can be reset, which can facilitate the staff to take out the upper side beam of the inner plate of the B-pillar that has been punched, thereby improving the punching efficiency of the device;

[0004] However, it has certain disadvantages: when the drilling position of the side beam on the inner plate of the column is at the end, in order to prevent the side beam from tilting, the operator usually needs to manually support the side beam, which not only increases the complexity and difficulty of the operation, but also reduces work efficiency. Long-term manual support can easily cause operator fatigue, and the hands will shake unconsciously during this process, resulting in inaccurate drilling position. Utility Model Content
