Problems solved by technology
[0003] However, this multi-axis automatic locking screw machine uses electric or air batches as the tightening power. The torque of commercially available electric or air batches is less than 5N.m, which cannot meet the tightening needs of large torques. The torque is realized by the mechanical mechanism, it is difficult to accurately adjust the torque required by the process; the feed of the screw chuck is driven by the cylinder or the oil cylinder, and its feed speed is constant, resulting in the workpiece locked by multiple screws during work It is warped, and there are even locking defects such as sliding teeth and missing locks

The invention provides an automatic locking screw machine, belongs to the technical field of machinery and aims at solving the problems of small torque, tooth sliding, locking missing and the like ofthe existing automatic locking screw machine when an electric screwdriver or a wind screwdriver is adopted as power drive. The automatic locking screw machine comprises a vertical plate which is vertically arranged; a top plate is fixedly connected to the top of the vertical plate and is provided with an oil cylinder; one side of the vertical plate is provided with a supporting plate which is arranged below the top plate and is driven by the oil cylinder to move up and down; the supporting plate is provided with a screw chuck driven by a drive structure; the automatic locking screw machine further comprises a PLC (Programmable Logic Controller) with a touch screen; the oil cylinder and the drive structure are connected with the PLC; a retarding structure used for retarding a feeding speedof the supporting plate when a screw in the screw chuck is in contact with a threaded hole of a workpiece is arranged between the oil cylinder and the supporting plate; and a guide structure is arranged between the vertical plate and the supporting plate. The automatic locking screw machine has the advantages of large locking torque, good locking effect and the like.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to an automatic screw locking machine. Background technique [0002] The automatic locking screw machine is a machine used to replace the traditional manual screw tightening. The automatic screw locking machine includes an automatic finishing unit, an automatic screw conveying unit, an automatic screw tightening unit, and a detection unit during the locking process. The multi-axis automatic locking screw machine is to set two or more tightening shafts on the support plate at the same time, and a screw chuck is provided at the lower end of each tightening shaft, and two or more than two The screw is screwed, which greatly improves the work efficiency. [0003] However, this multi-axis automatic locking screw machine uses electric or air batches as the tightening power. The torque of commercially available electric or air batches is less than 5N.m, which cannot meet the tightening ne...
