Problems solved by technology

[0005] 1. When the lock nut is loaded, although all the nuts are placed horizontally, there is an angle between each nut when feeding, which makes it impossible to accurately absorb each nut and reduce the feeding efficiency
[0006] 2. Poor positioning accuracy of the connecting parts, resulting in the need for repeated assembly when assembling other components later, which reduces production efficiency
[0007] 3. When the connecting piece and the mandrel are tightened, the mandrel cannot be fixed accurately, and the rotating mechanism cannot be quickly combined with the jig, resulting in low tightening efficiency

Embodiment Construction

[0031] Such as figure 1As shown, a hydraulic buffer piston assembly assembly equipment includes a turntable assembly device 1 , a mandrel tightening device 2 and a lock nut feeding and tightening device 9 . The turntable assembly device 1 is provided with a mandrel tightening station and a locking nut feeding and tightening station. The position of the mandrel tightening device 2 matches the mandrel tightening station. The position of the locking nut feeding and tightening device 9 is matched with the locking nut feeding and tightening station. The mandrel tightening device 2 is used for vertically tightening the mandrel on the connector. The locking nut feeding and tightening device 9 is used for feeding the locking nut onto the mandrel, and tightening the locking nut so that the recovery valve is fixed between the limit nut and the locking nut. The lock nut feeding and tightening device 9 adopts a lock nut feeding and tightening device used for piston assembly production....

Abstract

The invention relates to the field of hydraulic buffer production and assembly, in particular to a lock nut feeding and tightening device for piston assembly production. The lock nut feeding and tightening device comprises a lock nut feeding mechanism. The lock nut feeding mechanism comprises a lock nut material disc, a lock nut feeding rail, a lock nut vibrator, a lock nut positioning block, a positioning block installation base and a positioning block lifting air cylinder. The discharging end of the lock nut material disc is connected with the feeding end of the lock nut feeding rail. The lock nut vibrator is installed at the lower portion of the lock nut feeding rail. The discharging end of the lock nut feeding rail is connected with the lock nut positioning block. The lock nut positioning block is provided with a lock nut positioning groove. The end, close to the lock nut feeding rail, of the lock nut positioning groove is provided with a guide part. The end, away from the lock nutfeeding rail, of the lock nut positioning groove is provided with a sharp corner. According to the lock nut feeding and tightening device, lock nuts are positioned through the sharp corner, the placement forms of the nuts on the lock nut positioning block are consistent, and suction of an electric screwdriver is facilitated.

Description

technical field [0001] The invention relates to the field of production and assembly of hydraulic buffers, in particular to a locking nut feeding and tightening device for piston assembly production and hydraulic buffer piston assembly assembly equipment. Background technique [0002] The shock absorber relies on hydraulic damping to buffer and decelerate the objects acting on it to a stop, which plays a certain degree of protection. It is suitable for mechanical equipment such as lifting transportation, elevators, metallurgy, port machinery, railway vehicles, etc. It is used as a safety buffer device to prevent mechanical damage caused by hard collisions during work. The piston assembly is an important part of the hydraulic shock absorber movement actuator. The piston assembly includes a connecting piece, a mandrel, a first stop ring, a piston, a guide sleeve assembly, a second stop ring, a limit nut, a recovery valve and a lock nut; the right end of the mandrel is threade...
