Description

Multi-size quick positioning device Technical Field The utility model belongs to the technical field of pigtail processing, and particularly relates to a multi-size rapid positioning device. Background The pigtail in the reformer is a pipe fitting which must be used, the pipe fitting has high temperature and high pressure phenomena in use, the pipe fitting must be caused to have thermal expansion and cold contraction, and in order to prevent the thermal expansion and cold contraction from stretching the pigtail, the pipe fitting must be bent into a certain shape. However, the size control of the pipe bending machine is troublesome in the bending process of the pipe, the pipe bending machine can only be ensured by manually scribing in advance, the working efficiency is affected to a certain extent, and meanwhile, errors can be generated during scribing. Disclosure of utility model The utility model aims to provide a multi-size quick positioning device, which does not need to score for many times, reduces error generation during score-making, and can improve working efficiency. In order to solve the technical problems, the utility model provides a multi-size quick positioning device which is arranged on a pipe bending machine for processing tail pipe fittings, and comprises: A fixing frame; The screw rod is fixedly arranged on the fixing frame; The positioning blocks are sleeved on the screw rod at intervals, two sides of each positioning block are locked on the screw rod through fixing nuts, and meanwhile, the positioning blocks can rotate around the screw rod, so that the bottoms of the positioning blocks are in rotary abutting connection with the fixing frame. Preferably, the fixing frame is of an L-shaped plate structure, and two ends of the L-shaped plate further comprise integrally formed and welded fixing lug plates used for mounting two ends of the screw rod. Preferably, the screw rod positioning device further comprises a bearing, the positioning block is sleeved with the screw rod through the bearing, and stop limiting is carried out on two end faces of the bearing through the fixing nut, so that the positioning block can slide and rotate along the screw rod. Preferably, the positioning block comprises a rotating arm and an abutting plate, the rotating arm and the abutting plate are integrally connected, and the bearing is welded on a rotating hole of the rotating arm. Compared with the prior art, the utility model has the following beneficial effects: According to the utility model, the multi-dimension positioning device is arranged to replace manual scribing and bending, so that the dimension control is accurate, each branch pipe does not need to be scribed, the error in scribing is reduced, and the working efficiency can be improved.
