Automatic thread nail graining machine

Abstract

The invention discloses an automatic thread nail graining machine. The graining machine comprises a machine body, an automatic discharging device, a blanking control mechanism, a feeding mechanism, a crankshaft and connecting rod mechanism and a driving device. A sliding rail, a ram arranged to be matched with the sliding rail, a movable washboard and a graining board are arranged on the machine body, and a feeding port is formed in the feeding mechanism and arranged under a blanking port of the blanking control mechanism; a connecting rod of the crankshaft and connecting rod mechanism is hinged to the ram, a first collision block and a second collision block are arranged on the ram, the driving device drives the ram trough the crankshaft and connecting rod mechanism to move on the sliding rail in a reciprocating mode, in the feeding stroke of the ram, the first collision block controls the blanking control mechanism to perform blanking, when thread nails are conveyed to the feeding port of the feeding mechanism, the second collision block controls the feeding mechanism to convey the thread nails to a gap, located between the movable washboard and the graining board, in the sliding rail, and the thread nails are subjected to graining in the return stroke of the ram. The automatic thread nail graining machine can feed and machine the thread nails automatically, and effectively improve production efficiency and product quality.

Description

technical field [0001] The invention relates to a machine for processing tooth nail rubbing parts, in particular to an automatic tooth nail rubbing machine. Background technique [0002] Dental impression nails are one of the main medical devices used in oral dentistry to make various types of dentures, orthodontics and dental restorations for patients with dental diseases such as tooth loss, tooth disorder, and abnormal shape of the gums. At present, the dental impression nails (which have a structure such as figure 1 shown), consists of a nail body 12-1 with a cone and a nail top 12-2 with an ear. At present, the nail top 12-2 with fringe is manually put into the machining part by hand, and then the machine is driven by hand to shape the nail top with fringe. Workers are required to set the machine to operate and manually feed the materials. Not only is the efficiency low, but the machine is driven by workers and it is easy to cause the size of the screw to be unstable, ...

AI Technical Summary

Problems solved by technology

At present, the nail top 12-2 with fringe is manually put into the machining part by hand, and then the machine is driven by hand to shape the nail top with fringe. Workers are required to set the machine to operate, and manual feeding is not only inefficient, but also the machine is driven by workers, which may easily cause the size of the screw to be unstable, thus affecting the accuracy of the rubbed part of the screw
