[0005] The technical solution adopted by the utility model to solve the technical problem is: a three-way joint turning processing clamping tool, including a machine tool body, a machine tool spindle is arranged at the right end of the machine tool body, a first mounting frame is fixedly installed at the end of the machine tool spindle, a second mounting frame is movably installed inside the first mounting frame, two groups of profiling blocks are slidably installed up and down in the second mounting frame, and the two groups of profiling blocks are used to clamp the three-way joint.

[0006] Furthermore, a motor is fixedly mounted on the bottom of the first mounting frame, a power output shaft of the motor is fixedly connected to a second mounting frame, a rotating shaft is fixedly mounted on the upper end of the second mounting frame, and an upper end of the rotating shaft is movably mounted on the first mounting frame.

[0007] Furthermore, a mounting box is provided on the outer side of the motor, and the mounting box is fixedly mounted on the lower end of the first mounting frame.

[0008] Furthermore, a counterweight block is fixedly mounted on the upper end of the first mounting frame.

[0009] Furthermore, a group of telescopic devices are fixedly installed at the upper and lower ends of the second mounting frame, and a group of contour blocks are fixedly installed at the telescopic ends of the telescopic devices.

[0010] Furthermore, the internal structural specifications of the profiling block correspond to the outer shape of the three-way joint.

[0011] The beneficial effect of the utility model is that two groups of telescopic devices are started at the same time, so that two groups of profiling blocks clamp the three-way joint, and then the main shaft of the machine tool is rotated to process one side of the three-way joint. After the processing is completed, the motor is started, and the second mounting frame is driven by the motor to rotate, and the main shaft of the machine tool is rotated to process the other side of the three-way joint respectively. The above operation is repeated to complete the processing of the three sides of the three-way joint. There is no need to manually change the direction of the three-way joint, so that automatic processing is realized and work efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
