Claims

[Scope of utility model registration request]

A pipe fitting clamping device consisting of a pair of movable and fixed clamp halves that are pivotally connected to be expandable in two, and holding a pipe to be fused to a pipe fitting clamped by the pipe fitting clamping device. A pipe fitting fusion device in which pipe clamp devices and pipe clamp devices are connected to each other by a guide rod so that they can approach and separate from each other, and by moving one of these clamp devices toward the other, the pipe fitting can be pressed against the pipe and fused. In the machine, the torque tightening device for controlling the tightening torque of the pipe fitting clamping device includes a clamp bolt connected to the fixed clamp half-resting portion at a position opposite to a pivot point with the movable clamp half-resting portion of the pipe fitting clamping device. , a clamp bolt tightening member that is screwed onto the clamp bolt and engages the movable clamp half-rest to fasten both clamp half-rests, and a clamp that is attached to the clamp bolt tightening member to rotate it. A knob is provided between the clamp bolt tightening member and the clamp knob, and the rotation transmission of the clamp knob to the clamp bolt tightening member is interrupted only when a load of a predetermined value or more is applied to the clamp bolt tightening member. A constant torque transmission mechanism is interposed therebetween, and the constant torque transmission mechanism is formed by a spring biased pusher provided on one of the clamp knob and the clamp bolt tightening member, and a corresponding groove provided on the other. Features a torque tightening device for pipe joint fusion splicers.
