Problems solved by technology

[0002] Metal pipe fittings need to be polished on the outer wall and inner wall of the pipe fittings before use. During the polishing process of the pipe fittings, in order to drive the pipe fittings to rotate, the polishing equipment is placed on the outer side or inner hole of the pipe fittings during the rotation process, and the polishing equipment can be used to It performs polishing treatment. Now the polishing process generally clamps the pipe fittings by CNC lathe, and the spindle drives the pipe fittings to rotate. However, in this way, the clamped parts cannot be polished, and only part of the pipe fittings can be polished, and the polishing work will occupy the machine tool. , the existing fixture only has a clamping function and cannot drive the workpiece to rotate. If the rotating device and the clamping device are combined, the power supply problem of the rotating device will be difficult to solve, and the wires will be exposed, easy to entangle and oxidize

Embodiment 1

[0033] combine Figure 1-Figure 3 , a polishing and clamping tool for pipe fittings provided in this embodiment includes a clamping end and a supporting end. During the processing of pipe fittings, it is necessary to fix or support both ends of the pipe fittings. This embodiment is only used to solve the problem of the clamping end. Therefore, only the device at the clamping end is mentioned. The clamping end includes a fixed disc 2 and a support 1 for supporting the fixed disc 2. The fixed disc 2 is a disc, and the fixed disc 2 is fixed inside the support 1. The fixed disc 2 cannot Rotate, a number of support claws 3 in a circumferential array are installed in one end surface of the fixed disk 2, the sliding direction of the support claws 3 points to the axis, and several support claws 3 can only move toward the center of the circle at the same time or move away from it at the same speed. Sliding in the direction of the center of the circle, a rotatable turbine disk 6 is inst...

Embodiment 2

[0039] combine Figure 10 , the rotator 10 is an ellipsoid. When the rotator 10 is an ellipsoid, the ellipsoid is an ellipsoid formed by rotating with the minor axis of the ellipse as the axis. This type of ellipsoid is an oblate spheroid with equal longitudinal length In the case of , the depth of the annular groove is deeper, the contact area with the conductor 13 is larger than that of the spherical shape, and the resistance becomes smaller. If other conditions are not considered, the larger the contact area, the smaller the resistance. According to the formula: P=I*I* R, large resistance, not easy to heat, not easy to age and burn out, not easy to overheat during the electrical connection process, and prolong the service life.

Abstract

The invention discloses a pipe fitting polishing and clamping tool and belongs to the technical field of tool clamps. The pipe fitting polishing and clamping tool comprises a fixing disc and a support used for supporting the fixing disc, and a plurality of supporting claws are installed on one end face of the fixing disc; driving bodies are installed on the supporting claws; rotatable driving shafts are installed at the ends, away from the corresponding supporting claws, of the driving bodies; and anti-bending parts are fixed to the positions, located on the corresponding supporting claws, of one sides of the driving bodies. A pipe fitting can be supported from inside to outside or from outside to inside and driven to rotate, and then machining of an inner hole or an outer ring face of the pipe fitting is completed; a conducting strip and an electric conductor which are electrically connected are arranged on the two sides of a rotating body correspondingly, and an external power source is transmitted to the driving device through the sliding device, so that the power supply problem of the driving device can be solved; in the electrifying process of a sliding device, small resistance is generated by increasing the contact area and the fitting degree among the conducting strip, the electric conductor and the rotating body; and according to the formula P=I*I*R, the resistance is reduced, so that heating is not prone to occurring, and the service life is prolonged.
