Multipurpose spindle structure

Abstract

The invention discloses a multipurpose spindle structure. The multipurpose spindle structure comprises a spindle, a main motor, a first transmission mechanism and a pumpback device. The main motor is connected with the first transmission mechanism, and the spindle is also connected with the first transmission mechanism. The first transmission mechanism is installed inside a first reduction box. The spindle is vertically installed inside a spindle box. The spindle is provided with an axial through hole. The pumpback device is detachably installed on the first reduction box. The spindle box is fixed to the lower end of the first reduction box. The pumpback device comprises a servo motor, a second reduction box and an electric cylinder which are arranged up and down. The servo motor is connected with the second reduction box. The second reduction box is connected with the electric cylinder. The output end of the electric cylinder is detachably connected with a connecting rod, and the connecting rod penetrates through the axial through hole to be arranged. The multipurpose spindle structure can be used as friction welding equipment and a CNC machining center, the friction welding equipment and the CNC machining center can be switched quickly and flexibly, the application range of the equipment is greatly widened, the requirement that one machine achieves multiple purposes by users is met, and the purchase cost of the equipment is greatly reduced.

Description

technical field [0001] The invention relates to a main shaft structure, in particular to a multi-purpose main shaft structure. Background technique [0002] With the domestic research and application of friction stir welding technology, the technology has gradually matured and stabilized, and has been widely used in high-speed rail, aerospace and pipeline welding. The advantages of friction stir welding are numerous, but one significant disadvantage is that when the stirrer leaves the weld, it will leave a dimple at the end of the weld, called a keyhole. The existence of the keyhole not only affects the appearance of the weld, but also affects the performance of the weld at the end of the weldment to a certain extent. [0003] With the development of friction welding technology, retraction friction stir welding properly solves the keyhole problem, so more and more manufacturers use retraction friction welding for welding. figure 1 It is a structural schematic diagram of a ...

AI Technical Summary

Problems solved by technology

When the manufacturer needs to transform production or temporarily increase the CNC machining process, the special friction welding machine can only be idle, and the CNC machining center needs to be purchased separately, which brings great pressure on the production cost of the manufacturer.
