Description

Technical Field

[0001] The utility model relates to a multi-purpose turning jig for a vertical lathe, belonging to the technical field of vertical lathe equipment in the metallurgical industry. Background Art

[0002] As an important accessory of the vertical lathe, the turning jig is a commonly used fixing device for turning vertical rollers in the production preparation workshop of the steel rolling mill. Its main function is to fix the worn vertical rollers off the line through the vertical lathe jig and then re-turn them using the vertical lathe to prevent serious defects in the surface quality of the steel products caused by the wear of the vertical roller surface, and even steel sticking and steel piling accidents during the finishing rolling process.

[0003] The original vertical lathe had a single jig. When turning the worn vertical rollers on the offline machine, it was necessary to first select a lathe jig with the corresponding vertical roller specifications and then fix it before turning. This method would lead to a high frequency of jig replacement, increasing the workload. Frequent replacement could easily lead to failure of the clamping device at the bottom of the lathe, increasing maintenance costs and labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-purpose turning jig for a vertical lathe, which can meet the needs of a variety of specifications of vertical rollers in the workshop and be directly fixed on the vertical lathe for use, thereby reducing the frequency of jig replacement, lowering the failure rate of the lathe, improving the turning operation efficiency, and solving the problems existing in the background technology.

[0005] The technical solution of the utility model is:

[0006] A multi-purpose turning jig for a vertical lathe comprises a first circular ring and a second circular ring. The first circular ring is arranged above the second circular ring and the two circular rings are welded together. The inner diameter of the first circular ring is larger than the inner diameter of the second circular ring and smaller than the outer diameter of the second circular ring. The outer diameter of the first circular ring is larger than the outer diameter of the second circular ring. A stepped groove is provided on the upper end face of the first circular ring. The stepped groove is composed of the connected first and second grooves. The first circular ring is arranged above the second groove. The diameter of the first circular ring is larger than the diameter of the second groove. The diameter of the second groove is larger than the outer diameter of the second circular ring. A plurality of through holes are provided on the first circular ring. A vertical roller is placed on the upper end face of the first circular ring. The first circular ring is connected to the vertical roller via the through holes and the hanging ring.

[0007] There are eight through holes, which are evenly divided into four groups. The centers of through holes in different groups are arranged on different circumferences, and the centers of two through holes in the same group are arranged on the same circumference and are 180 degrees symmetrical.

[0008] Two adjacent through holes are arranged on the ring 1 at an interval of 45 degrees.

[0009] The depths of groove 1 and groove 2 are the same, both 3 mm. The maximum depth of the stepped groove is 6 mm. The diameter of groove 1 is 532 mm, and the diameter of groove 2 is 463 mm.

[0010] The ring 1 and the ring 2 are both cut from steel plates. The outer diameter of the ring 1 is 656 mm and the inner diameter is 353 mm; the outer diameter of the ring 2 is 440 mm and the inner diameter is 323 mm.

[0011] The diameter of the through hole is 26 mm.

[0012] By adopting the utility model, the vertical roller to be processed is directly placed on the circular ring 1. It only needs to be aligned with the reserved through-hole, and the lifting ring is passed through the through-hole of the circular ring 1 and the fastening hole of the vertical roller in sequence, and the circular ring 1 and the vertical roller are fixed and can be used without replacing the jig, which reduces the time for jig selection and installation and reduces the preparation time for turning operations, thereby improving work efficiency.

[0013] The beneficial effects of the utility model are: it can reduce the efficiency of mold replacement, extend the service life of the lathe, reduce equipment loss, reduce maintenance costs, ensure the quality of vertical roller turning, improve the working efficiency of the rolling mill, eliminate equipment hidden dangers, and reduce the labor intensity of workers.

[0018] The present invention will be further described below with reference to the accompanying drawings and through examples.

[0019] A multi-purpose turning jig for a vertical lathe comprises a circular ring 1 and a circular ring 2. The circular ring 1 is arranged above the circular ring 2 and welded together. The inner diameter of the circular ring 1 is larger than the inner diameter of the circular ring 2 and smaller than the outer diameter of the circular ring 2. The outer diameter of the circular ring 1 is larger than the outer diameter of the circular ring 2. A stepped groove is provided on the upper end face of the circular ring 1. The stepped groove consists of a connected groove 1 and a groove 2. The groove 1 is arranged above the groove 2. The diameter of the groove 1 is larger than the diameter of the groove 2. The diameter of the groove 2 is larger than the outer diameter of the circular ring 2. A plurality of through holes are provided on the circular ring 1. A vertical roller 9 is placed on the upper end face of the circular ring 1. The circular ring 1 is connected to the vertical roller 9 via the through holes and a hanging ring 10.

[0020] There are eight through holes, which are evenly divided into four groups. The centers of through holes in different groups are arranged on different circumferences, and the centers of two through holes in the same group are arranged on the same circumference and are 180 degrees symmetrical.

[0021] Two adjacent through holes are arranged on the ring 1 at an interval of 45 degrees.

[0022] The depths of the groove 1 3 and the groove 2 4 are the same, both 3 mm. The maximum depth of the stepped groove is 6 mm. The diameter of the groove 1 3 is 532 mm, and the diameter of the groove 2 4 is 463 mm.

[0023] The ring 1 and the ring 2 are both cut from steel plates. The outer diameter of the ring 1 is 656 mm and the inner diameter is 353 mm; the outer diameter of the ring 2 is 440 mm and the inner diameter is 323 mm.

[0024] The diameter of the through hole is 26 mm.

[0025] In this embodiment, two steel plates are cut into a circular ring 1 and a circular ring 2. The dimensions of the circular ring 1 are φ656 outer diameter and φ353 inner diameter; the dimensions of the circular ring 2 are φ440 outer diameter and φ323 inner diameter. The circular rings 1 and 2 are fixed on the outer and inner sides of the connection by arc welding. A groove 3 with a diameter of φ532 and a depth of 3 mm is first turned on the upper end face of the circular ring 1, and then a groove 2 4 with a diameter of φ463 and a depth of 3 mm is turned to form a stepped groove with a maximum depth of 6 mm. Finally, vertical holes are drilled on the upper end face of the circular ring 1 to form through holes. The through holes have a diameter of φ26 mm. There are eight through holes, namely, four groups of two through holes 1 5, two through holes 2 6, two through holes 3 7, and two through holes 4 8. The centers of the two through holes in the same group are arranged on the same circumference and are 180 degrees opposite to each other. Two adjacent through holes are arranged on the circular ring 1 at a 45° interval.

[0026] The utility model adopts a stepped groove design, the main function of which is to avoid bulges that may be caused by the vertical rollers for installing the gland, which reduces the fastening effect of the mold.

[0027] By adopting the utility model, the utility model is fixed by the vertical lathe clamp 11, and the vertical roller 9 to be processed is directly placed on the ring 1. It is only necessary to align the reserved through-holes, and pass the hanging ring 10 through the through-holes of the ring 1 and the fastening holes of the vertical roller 9 in sequence, and fix the ring 1 and the vertical roller 9 before use. When replacing the vertical roller, it is only necessary to align the fastening holes corresponding to the vertical roller to realize the turning operation, and there is no need to replace the jig.
