Description

A turning tool for a cylindrical workpiece

technical field

The utility model relates to an overturning tool for overturning a large cylindrical workpiece.

Background technique

The surface painting operation of the large cylindrical workpiece in the existing high-voltage electrical switch needs to hang the cylinder on the transport platform and then send it to the painting workshop for painting. During the spraying process, the cylinder needs to be turned so as to spray on various parts of the cylinder. The traditional method is to use manual handling and turning, which not only increases the labor intensity of workers, but also easily causes scratches and bumps, and there are dead spots for spraying, which cannot guarantee the spraying quality of cylindrical workpieces. At the same time, manual turning of workpieces is prone to damage Accidents pose a serious safety hazard. In addition, after the spraying operation is completed, the cylindrical workpiece needs to be equipped with a large auxiliary hoist to lift the cylindrical workpiece to the drying workshop. The secondary hoisting of the cylindrical workpiece increases the operation process and makes its production efficiency low.

Utility model content

The purpose of the utility model is to provide a turning tool for a cylindrical workpiece to solve the problems of low safety and poor painting quality of manually turning the workpiece.

The technical scheme of the utility model is: a turning tool for a cylindrical workpiece, including a bracket for suspending the cylindrical workpiece. Two fixed pulleys are arranged at relative intervals in the horizontal direction on the bracket, and steel wire ropes are respectively arranged on the two fixed pulleys. , the two ends of the steel wire rope are respectively fixed with bolt-type lifting rings for corresponding connection with the process holes on the two ends of the cylindrical workpiece.

The two fixed pulleys are respectively hung on the bracket through correspondingly provided rotating rings.

The support is mainly composed of uprights separated at intervals and a crossbeam spanning the tops of the two uprights, and the two fixed pulleys are suspended at the bottom of the crossbeam.

Two position adjustment plates are fixed at the bottom of the crossbeam at relative intervals. The two position adjustment plates extend longitudinally along the crossbeam. Adjustment holes are arranged on the two position adjustment plates along their extension directions. The two fixed pulleys are according to The lengths of the cylindrical workpieces are respectively suspended in the adjustment holes of the corresponding position adjustment plates through the rotating suspension rings.

The bracket is made by welding steel pipes.

The beam is made of I-beam.

Both ends of the upper part of the beam are respectively fixed with ring plates for connecting with a crane.

The utility model has a simple structure. When in use, the two process holes arranged at opposite intervals on the two ends of the cylindrical workpiece are respectively connected with the two ends of a steel wire rope bypassing the fixed pulley with the corresponding suspension rings. The rotation of the cylindrical workpiece is driven by the wire rope to achieve a 360° rotation, which avoids manual handling, flipping, scratching and bumping the surface of the cylindrical workpiece, and there is no dead angle in the spraying work, thereby improving the spraying quality of the cylindrical workpiece. At the same time, the cylindrical workpiece is completed by using tooling The overturning of the workpiece effectively avoids the occurrence of bruising and smashing accidents, and solves the problem of large safety hazards in manual handling.

Detailed ways

The specific embodiment of the cylindrical workpiece turning tool of the present utility model is shown in Fig. 1, Fig. 2 and Fig. 3, which includes two brackets 1 which are welded by steel pipes and arranged at relative intervals, and are fixedly erected on the top of the two brackets 1 by an I-shaped The crossbeam 2 made of steel, the lower part of the crossbeam 2 is provided with two position adjustment plates 3 at intervals relative to each other. A number of position adjustment holes, in the corresponding position adjustment holes of the two position adjustment plates 3, a rotating suspension ring 4 is suspended by a hook respectively, and fixed pulleys 5 are respectively connected to the lower parts of the two rotation suspension rings 4, and steel wire ropes 6 are arranged on the two fixed pulleys 5, The two ends of the two steel wire ropes 6 are respectively fixed with bolt-type lifting rings 7 for corresponding connection with the process holes provided at intervals on the two ends of the cylindrical workpiece. The two ends on the top of the beam are also respectively fixed with ring plates 8 for connecting the crane.

When the turning tool of the utility model is in use, according to the length of the cylindrical workpiece, the two fixed pulleys are respectively suspended in the corresponding position adjustment holes in the position adjustment plate 3, and the steel wire rope 6 passes through the fixed pulley 5, and the two ends of the fixed pulley are bolted respectively. The type lifting rings are connected in the process holes arranged at intervals on the end surface of the cylindrical workpiece, so that the rotating lifting rings 7 and the steel wire ropes 6 form a certain angle. The flipper is installed in the painting workshop. After the surface of the cylindrical workpiece is degreased and washed, it is suspended under the beam 2 through the steel wire rope 6 connected with the bolt-type suspension ring 7 at both ends, and the painting operation is carried out. During the spraying process, it can be passed The steel wire rope 6 connected to both ends of the cylindrical workpiece and the fixed pulley 5 cooperate to realize the 360° rotation of the cylindrical workpiece, which ensures uniform spraying and no dead angle of painting, which improves the painting quality, and the steel wire rope 6 at both ends will not be cross-wound. During operation, the cylindrical workpiece is always in a suspended state, which reduces the labor intensity of workers, avoids the occurrence of scratches, bumps and manual flipping hazards, and ensures the safety of work. After the painting operation is completed, the ring plates 8 at both ends of the beam 2 are directly hoisted with a crane, and the turning tool is connected to the cylindrical workpiece and transported to the drying workshop together, thereby avoiding secondary hoisting and improving work efficiency.
