A multi-purpose spindle structure

Abstract

The multi-purpose main shaft structure disclosed by the present invention includes a main shaft, a main motor, a first transmission mechanism and a retracting device, the main motor is connected with the first transmission mechanism, the main shaft is connected with the first transmission mechanism, and the first transmission mechanism is installed in the first reduction box , the main shaft is installed upright in the main shaft box, the main shaft is provided with an axial through hole, the withdrawal device is detachably installed on the first reduction box, the main shaft box is fixed at the lower end of the first reduction box, and the withdrawal device includes an upper and lower setting The servo motor, the second reduction box and the electric cylinder, 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 runs through the axial through hole set up. The spindle structure can be used as friction welding equipment and CNC machining center, realizes fast and flexible conversion between friction welding equipment and CNC machining center, greatly expands the application range of equipment, meets the requirements of users for one machine with multiple functions, and greatly saves equipment procurement costs .

Description

A multi-purpose spindle structure technical field The present invention relates to a kind of main shaft structure, specifically a kind of multi-purpose main shaft structure. Background technique With domestic research and application of friction stir welding technology, the technology is gradually mature and stable, and has begun to be widely used. In high-speed rail, aerospace and pipeline welding. The advantages of friction stir welding are numerous, but it has one significant disadvantage, That is, when the stirring head leaves the weld, it will leave a dimple at the end of the weld, called a keyhole. The presence of the keyhole not only affects The appearance of the weld seam will also affect the weld performance of the end of the weldment to a certain extent. [0003] With the development of friction welding technology, the retraction friction stir welding properly solves the keyhole problem, so more and more Manufacturers use retraction friction welding for w...

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.
