Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

Referring to the accompanying drawings 1-6, the circle correcting tool for the circular ring workpiece is integrally arranged through the circle center of the circular ring workpiece 10 in an embedded mode and placed on the inner side of the circular ring workpiece, the circle correcting tool comprises correcting devices which are symmetrically attached to the inner wall of the circular ring workpiece 10 in a close mode through the circle center of the circular ring workpiece, and driving devices for driving the correcting devices to be far away or close to the correcting devices are arranged between the symmetrical correcting devices. Since the circular ring workpiece is generally formed by crimping and welding a plate material, the circular ring workpiece has poor roundness, and therefore, the roundness needs to be corrected. During operation, the curled and welded circular workpiece 10 is horizontally placed on the surface of the workbench, the correction devices are symmetrically attached to two sides of the inner wall of the circular workpiece 10, the symmetrical correction devices are connected through the driving device, external force is applied through the driving device, the symmetrical correction devices are separated from each other and attached to the inner wall surface of the circular workpiece 10, the circular workpiece 10 deforms under the action of the external force to gradually approach to a regular circular structure, and rapid correction of roundness is achieved. The driving device is driven reversely, so that the symmetrical correcting devices can approach to each other and are separated from the contact with the inner wall surface of the circular workpiece 10, the circular correcting tool or the circular workpiece 10 can be rotated, and the roundness of the rest positions of the inner wall surface of the circular workpiece 10 can be corrected in the above mode until the roundness of the circular workpiece 10 is corrected to the required precision.

Specifically, as shown in fig. 1 and 3, the correction device is an arc correction plate 1 tightly attached to the inner wall of the circular workpiece 10, and the driving device includes a threaded sleeve 2 disposed on the inner side wall of each arc correction plate 1, and a double-head adjusting screw 3 with threads passing through the threaded sleeve 2. Establish the both ends at double-end adjusting screw 3 through threaded sleeve 2 with the circular arc correction plate 1 cover of both sides, and wholly place into in the ring work piece 10, through rotatory double-end adjusting screw 3, make the circular arc correction plate 1 at both ends all hug closely in ring work piece 10 inner wall both sides gradually, and under continuous drive, order about ring work piece 10 and take place deformation, and tend to circular structure gradually, drive withdrawal circular arc correction plate 1 and break away from the contact with ring work piece 10 inner wall after that, wholly rotate double-end adjusting screw 3 and circular arc correction plate 1, can carry out the circularity correction in other positions. It is mainly applied to a trimming operation of a circular arc correction plate 1 having an elliptical shape, as shown in fig. 2, of the shape of the circular arc correction plate 1 to be trimmed.

In order to repair the inner wall defect (the inner wall has a surface protrusion as shown in a in fig. 4) of the circular ring workpiece 10, as shown in fig. 5-6, the threaded sleeve 2 is detachably sleeved on one side of the double-head adjusting screw rod 3, and the end part of the threaded sleeve 2 is provided with a repair positioning plate 1a with the length larger than that of the circular arc correction plate 1. When repairing the protruding defect to ring work piece 10 inner wall, will restore locating plate 1a and connect in 3 one ends of double-end adjusting screw through threaded sleeve 2, place its whole in ring work piece 10, and drive double-end adjusting screw 3 rotatory, make and restore locating plate 1a and hug closely in 10 inner wall one sides of ring work piece, and the circular arc correcting plate 1 of opposite side corresponds with surperficial protruding defect, and it is rotatory to continuously drive double-end adjusting screw 3, exert external force through circular arc correcting plate 1, cause surperficial arch to eliminate gradually. Wherein repair locating plate 1a has longer length, can hug closely and support ring work piece 10 at ring work piece 10 inner wall one side, avoids taking place the problem of deformation in ring work piece 10 whole when exerting restoration external force.

In order to facilitate the detection of the roundness of the corrected circular workpiece 10, as shown in fig. 1, a supporting disk 4 is disposed at the bottom of the double-end adjusting screw 3, a supporting limiting plate 41 is disposed on the supporting disk 4, the supporting disk is rotatably sleeved on the double-end adjusting screw 3 and axially limits the double-end adjusting screw, and a rotary detection ring 42 is rotatably disposed on the periphery of the supporting disk 4. During operation, the circular arc correction plates 1 are sleeved at two ends of the double-end adjusting screw rod 3, so that the distance between the outer side walls of the symmetrical circular arc correction plates 1 is equal to the standard inner diameter of the circular ring workpiece 10, the corrected circular ring workpiece 10 is placed on the rotary detection ring 42 to rotate, the whole circular correction tool is limited to be positioned relative to the support plate 4 through the support limiting plate 41, deflection is avoided, whether contact blockage exists between the circular arc correction plates 1 and the inner wall of the circular ring workpiece 10 in the rotating process of the circular ring workpiece is detected, if the contact blockage exists, the roundness of the circular ring workpiece 10 needs to be corrected again, the position to be corrected is marked, and if the circular ring workpiece 10 can rotate smoothly, the roundness correction is completed.

The principle of the utility model is that: during operation, the circular arc correcting plates 1 on two sides are sleeved at two ends of the double-end adjusting screw rod 3 through the threaded sleeve 2, the circular ring workpiece 10 formed by curling and welding is flatly placed on the rotary detection ring 42, the double-end adjusting screw rod 3 is rotated, the circular arc correcting plates 1 at two ends are gradually attached to two sides of the inner wall of the circular ring workpiece 10, the circular ring workpiece 10 is driven to deform under continuous driving, the circular ring workpiece gradually tends to a circular structure, then the circular arc correcting plates 1 are driven to retract and are separated from contact with the inner wall of the circular ring workpiece 10, and the circular ring workpiece 10 is rotated and circular correction in other directions can be carried out.

After the positioning plate 1a is replaced and repaired, the defects on the inner wall surface of the circular ring workpiece 10 can be repaired. After the overall correction is completed, the circular arc correction plates 1 are sleeved at two ends of the double-end adjusting screw rod 3, so that the distance between the outer side walls of the symmetrical circular arc correction plates 1 is equal to the standard inner diameter of the circular ring workpiece 10, the corrected circular ring workpiece 10 is placed on the rotation detection ring 42 to rotate, the whole circular correction tool is limited to be positioned relative to the support plate 4 through the support limiting plate 41, whether contact obstruction exists between the circular arc correction plates 1 and the inner wall of the circular ring workpiece 10 in the rotation process of the circular ring workpiece 10 is detected, if the contact obstruction exists, the roundness of the circular ring workpiece 10 needs to be corrected again, the position to be corrected is marked, and if the circular ring workpiece 10 can rotate smoothly, the roundness correction is completed.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
