Problems solved by technology

However, at least three motors are required to realize this action function. One drives the tension nut, the other drives the bolt nut, and the other is responsible for the lifting of the tensioner. Therefore, the overall structure has a large volume and high energy consumption. not widely available

Abstract

The invention relates to a single-motor driven type bolt stretcher gripper. The single-motor driven type bolt stretcher gripper comprises a power device, a guide device, a reversing device, a liftingdevice and a machine frame, wherein the machine frame comprises a bottom plate and a fixing plate, the fixing plate is arranged right above the bottom plate, the guide device comprises a guide columnand a linear bearing, the power device comprises a motor and a speed reducer, the reversing device comprises an input shaft, a gear, a reversing wheel, a belt pulley shaft, a gear shaft, a square pin,a reversing shifting fork and an electromagnet, the speed reducer is connected with the reversing wheel through the input shaft, the gear is meshed with the gear shaft, the belt pulley shaft is connected with a belt pulley, the belt pulley shaft is provided with the square pin so as to drive a stretching nut of a bolt stretcher to rotate, the electromagnet is arranged at the top of the reversingshifting fork, the lifting device comprises the belt pulley, a lead screw, a fixing seat, a lead screw nut and a lifting plate. The single-motor driven type bolt stretcher gripper has the advantages that the structure is simple and compact, the stretching nut and a bolt nut are driven by the single motor, moreover, the actions of being close to and away from the bolt are completed at the same time, the size is small, energy is saved, and consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of bolt grippers, in particular to a single motor-driven bolt tensioner gripper. Background technique [0002] The bolt tightening method is one of many bolt tightening methods. Because it obtains the bolt pre-tightening force directly, it causes less damage to the bolt, especially for long and large bolts. Therefore, more and more bolt tensioning methods are used for the fastening of key bolts. The bolt tensioner is a tool to realize the bolt tension method. How to use the bolt tensioner: 1. The bolt tensioner is required to be centered and perpendicular to the bolt to be tightened; 2. Use a wrench to rotate the tension nut in the middle clockwise to screw it into the bolt to be tightened. Length; 3. Input high-pressure hydraulic oil into the bolt tensioner to make the tension nut stretch the bolt to the set value and keep it; 4. Rotate the bolt nut clockwise and tighten the nut; 5. Release the bolt in th...
