Description

Technical Field

[0001] The utility model relates to the technical field of screw machine lifting, in particular to a lifting device for a screw machine. Background Art

[0002] A screw machine is a small machine for automatically locking screws. Its action structure generally can be divided into two parts: a feeding part and an electric screwdriver part. The feeding part is responsible for screening and providing screws, and the electric screwdriver part is responsible for picking up screws and locking them. The emergence of the screw machine not only improves the operation efficiency but also reduces the labor intensity of manual work.

[0003] In the prior art, the height of the screw machine is fixed during operation, resulting in poor operability for workers of different heights. At the same time, since the internal parts of the screw machine are all precision parts, when the position is moved, the components are loosened, affecting the screw conveying work and the use. During the shock absorption work, the stability is poor. For example, the rigid support structure has a poor seismic effect during movement, resulting in limitations in use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lifting device for a screw machine. The threaded column rotates and then is in threaded cooperation with the lifting plate, so as to realize threaded movement. When the piston rod rises, the sleeve is jacked up, so as to lift the screw machine main body. After lifting, it can be adjusted according to the use height of different workers.

[0005] To achieve the above purpose, a lifting device for a screw machine is provided, including: a support bottom plate and a lifting plate. Four corners of the upper part of the support bottom plate are fixedly connected with sliding rods, and the outside of the sliding rods is slidably fitted with the lifting plate. A threaded column is threadedly connected to the middle part of the lifting plate. Four corners of the lifting plate are fixedly connected with piston rods, and the outside of the piston rods is sleeved with sleeves. A shock absorption spring is fixedly connected to the top end inside the sleeve, and the bottom end of the shock absorption spring is in contact and cooperation with the piston rod. The top end of the sleeve is fixedly connected with a screw machine main body, and a pin hole is formed between the screw machine main body and the sleeve;
