Description

Random cantilever crane for vertical lathe

Technical Field

The utility model relates to a vertical lathe hangs cantilever at random belongs to cantilever crane technical field.

Background

In the vertical lathe work, the shapes and the weights of parts needing to be machined are different, and when large and heavy parts are encountered, clamping and unloading become great problems. In life, a crane can be used for carrying large parts, but the crane is used for carrying parts of a machine tool; in lathe machining, the purpose of clamping and unloading parts is achieved by using a travelling crane, and the lathe machining is very inconvenient. If the machine tool is provided with a cantilever crane, parts needing to be machined can be moved lightly and loosely, and the machining efficiency of the vertical lathe is greatly improved.

Disclosure of Invention

An object of the utility model is to overcome the not enough of existence among the prior art, provide a vertical lathe cantilever crane at random, the device installs on the lathe, and convenient transport or uninstallation part have promoted lathe efficiency.

According to the utility model provides a technical scheme: the random cantilever crane for the vertical lathe comprises a mounting bracket, a suspension arm assembly, a cross beam, a motor, a pulley assembly, a lifting hook and a fixed shaft, wherein the mounting bracket is fixedly mounted at the top end of the vertical lathe; the beam is provided with a motor and a pulley assembly, the motor is electrified and an electric control signal is transmitted through an electric wire, the pulley assembly can slide left and right on a pulley track of the beam, and the lifting hook moves up and down through the pulley assembly.

Furthermore, the suspension arm assembly comprises a flange plate, a suspension arm and a plane bearing, the suspension arm is sleeved on the fixed shaft and can rotate around the fixed shaft, the top of the suspension arm is fixedly connected with the flange plate, and the flange plate is fixedly connected with the cross beam; the suspension arm is limited through a locking nut, and the upper end and the lower end of the suspension arm are respectively provided with a plane bearing.

Further, an oil bearing is arranged between the suspension arm and the fixed shaft.

Furthermore, a support frame is arranged between the cross beam and the flange plate.

Compared with the prior art, the utility model, have following advantage:

the vertical lathe random cantilever is hoisted on the machine tool upright column, and the vertical lathe random cantilever is compact and attractive, has a simple structure, is convenient to install and maintain, can easily move, clamp and unload machined parts without the help of an external hoisting device, reduces the labor force of operating personnel, and saves the cost.
