Description

Technical Field

[0001] The utility model relates to the technical field of metal rollers, in particular to a metal roller which is convenient for butt jointing. Background Art

[0002] Metal rollers are also called rollers or metal roller shafts. They are the general name for cylindrical parts that can roll on machines. Metal rollers are currently widely used in mechanical processing, automobile production, construction engineering equipment and other fields. The production of metal rollers requires forging, rough turning, tempering heat treatment, fine turning and grinding, among which the grinding process is one of the most important processes. Metal rollers are available in two types: integral and combined. They have superior performance, stable quality, high product processing precision, good wear resistance and high impact resistance.

[0003] However, the problem that the existing metal rollers are inconvenient to dock when in use has not been solved, which makes it inconvenient for workers to operate, affects the efficiency of docking between the metal rollers, and causes the overall processing flow and progress to be affected. At the same time, the docking is inconvenient, and the metal rollers lack pre-positioning when docking, which causes the metal rollers to easily move axially during docking. The position of the metal rollers also needs to be frequently adjusted, making docking inconvenient. Therefore, a new metal roller that is easy to dock is proposed. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the utility model is to provide a metal roller that is easy to dock, so as to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a metal roller that is easy to dock, including a roller body, a joint, a perforation, and a positioning end. The two ends of the roller body are fixedly connected with the joint, and the end of the joint is fixedly connected with the positioning end. A circle of depression is provided in the middle of the positioning end, and the end of the positioning end is a truncated cone-shaped end.

[0007] The joint is provided with a perforation;

[0008] The outer surface of the joint is sleeved with a sleeve head, the interior of the sleeve head is fixedly connected with a compensation sleeve, the inner side of the compensation sleeve is specifically sleeved with the joint, and the compensation sleeve is made of elastic material;

[0009] The two sides of the sleeve are fixedly connected with convex sections, and the convex sections are plugged with fasteners, which are plugged into the through holes and tightened at the ends;

[0010] The root of the inner side of the sleeve head is fixedly connected with a positioning sleeve, the port of the positioning sleeve is fixedly connected with an elastic sleeve, the elastic sleeve is inserted into the recess of the positioning end, and the truncated cone-shaped end of the positioning end is inserted into the positioning sleeve.

[0011] Preferably, in any of the above schemes, the roller body is welded to the joint, and the through hole is provided in the middle of the joint.

A compensation sleeve is made in the sleeve. The compensation sleeve is elastic and has a slightly smaller diameter. Even if there is a size error between the sleeve and the joint, the joint can be firmly inserted into the sleeve.

[0016] The end of the joint is designed with a positioning end, which serves as a pre-positioning and locking standard when the joint and the sleeve are fastened. The positioning end stretches the elastic sleeve and enters the positioning sleeve to lock it. At this time, the perforation of the joint is just aligned with the convex section of the sleeve. Then, relying on the alignment of the positioning end and the positioning sleeve, the joint can be rotated at will, and the joint will not move axially. After the perforation of the joint is aligned with the convex section, the fastener is inserted and the nut with a washer is tightened to complete the docking of the sleeve and the roller body joint. In this process, a compensation design is made, so that even if there is a size error between the sleeve and the joint, the joint can be firmly inserted into the sleeve;

[0017] A pre-positioning design is made. Relying on the alignment of the positioning end and the positioning sleeve, the joint can be rotated at will without axial displacement.
