Problems solved by technology
[0004] The purpose of the present invention is to provide a special spindle coupling for friction stir welding to solve the problem that the input and output ends of the spindle drive shaft are not connected due to the friction stir welding having an advancing angle of the spindle during the welding process proposed in the background technology. Coaxial, and the advance angle is constantly changing when welding curves, which makes the traditional direct coupling structure unable to achieve this action, and the problem of the transmission angle limit of the universal joint coupling

The invention relates to the technical field of spindle couplings, in particular to a special spindle coupling for friction stir welding, which includes a device body, the device body includes a coupling collar, and the number of coupling collars is two, An input end is provided inside the shaft coupling collar, and input locking expansion sleeves are installed inside the shaft coupling collar on both sides of the input end. In the present invention, a reinforcing mechanism is provided, and the staff moves the pressing rod to the direction of the insertion block, so that the auxiliary groove is moved to one side, so that the insertion block enters into the collar of the coupling, and then the staff By loosening the rotating shaft, the auxiliary groove is moved away from the coupling collar, so that the fixing rod is snapped into the socket rod, so that the reinforcement mechanism is fixed to the main body of the device, and with In this way, the main body of the device is reinforced, thereby prolonging the normal service life of the main body of the device.
Description
Technical field [0001] The present invention relates to the technical field of spindle coupling, specifically a special spindle coupling for friction stir welding. Background [0002] Friction stirring welding machine is a commonly used model on the market, the stirring head rotates at high speed and rubs with the welded workpiece, generating heat to form a thermoplastic layer, the stirring head and the workpiece are relatively moving, and the thermoplastic metal that is constantly formed in front of the mixing head is transferred to the back of the stirring head, filling the cavity behind it, thus forming a connection method. [0003] Because the friction stir welding has a forward angle in the spindle during the welding process, resulting in different shafts at the input and output ends of the spindle transmission shaft, and the forward angle is still constantly changing the angle when welding the curve, resulting in the traditional direct coupling structure can not achieve the...
