Automatic screw driving device

Abstract

The invention discloses an automatic screw driving device. A workbench is provided with an automatic screw feeding mechanism, a screw guiding tube, an automatic screw driving mechanism and a workpiece feeding mechanism, and the automatic screw feeding mechanism, the automatic screw driving mechanism and the workpiece feeding mechanism are fixed to the workbench by screws. The screw guiding tube is connected between the automatic screw feeding mechanism and the automatic screw driving mechanism, and the vibration disk of the automatic screw feeding mechanism is fixed to a vibration disk installation plate by screws. According to the automatic screw driving device, automatic screw driving is basically realized, the problems that screws are prone to loosing or gear smooth is caused by over high twisting force because the manner of manual screw driving is adopted in traditional assembly operation, the production efficiency is low, the labor cost is high, screw driving is inaccurate, and the twisting force for screw driving is over low are solved, and meanwhile, the defects of the existing screw driving machines in the market of being uncontrollable in pressure and low in safety and degree of automation are overcome.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an automatic locking device. Background technique [0002] Locking screws is the most basic and common assembly task in assembly manufacturing. [0003] At present, the vast majority of assembly operations still use the method of manually locking screws. This method is more suitable for small batch production processes, but for large batch production processes, there will be disadvantages of low production efficiency and high labor costs. Manual locking of screws also has certain requirements for operators. Inexperience will result in inaccurate locking, and the consistency of locking torque of each screw cannot be guaranteed. If the torque is too small, the screws will easily loosen, reducing the The reliability of the entire assembly work, the torque is too large, it is easy to slip the teeth, resulting in damage to the threaded holes of the assembled parts an...

Problems solved by technology

[0003] At present, the vast majority of assembly operations still use the method of manually locking screws. This method is more suitable for small batch production processes, but for large batch production processes, there will be disadvantages of low production efficiency and high labor costs.

Manual locking of screws also has certain requirements for operators. Inexperience will result in inaccurate locking, and the consistency of locking torque of each screw cannot be guaranteed. If the torque is too small, the screws will easily loosen, reducing the The reliability of the entire assembly work, the torque is too large, it is easy to slip the teeth, resulting in damage to the threaded holes of the assembled parts and even the scrapping of the entire part. In the current assembly operations, electric batches have been widely used, which can solve the problem of manual locking. The problem of inconsistent tightening torque is slightly simplified compared to the method of locking with a screwdriver, but for screw loading, manual removal is still required, and it is easy to cause injury to the operator

The existing screw locking machines in the market also have the disadvantage that the downward pressure is uncontrollable when locking, and the locking operation is still done manually
