Abstract

A replaceable roller, comprising a roller body (1), a roller sleeve (2), a locking ring (3), and keys (4); the roller sleeve (2) is sleeved on the roller body (1); first key slots (12) are formed at edges of two ends of a roller base (11) of the roller body (1); second key slots (21) are formed at both ends of an inner wall of the roller sleeve (2) corresponding to the first key slots (12); the first key slots (12) and the second key slots (21) are matched and then inserted with the keys (4), so that the roller body (1) and the roller sleeve (2) cannot rotate relatively, a groove (111) is formed in end faces of two ends of the roller base (11); the groove (111) is provided with threads; a retainer ring (31) is provided at one surface of the locking ring (3); the retainer ring (31) is provided with threads matched with the groove (111). By replacing the roller sleeve (2), the service life of the roller is prolonged, and thus the production cost is reduced. Moreover, the key slots (12, 21) are cooperatively used with the locking ring (3), ensuring the sleeve stability of the roller sleeve (2), and saw teeth of the inner ring of the locking ring (3) match with a locking block (5) to ensure fixation of the locking ring (3).

Description

一种可替换式轧棍Replaceable rolling stick 技术领域Technical field
本发明涉及轧棍结构，特别涉及一种可替换式轧棍。The present invention relates to a roll bar structure, and more particularly to a replaceable roll bar.
背景技术Background technique
轧棍在长期使用后，表面会有磨损，而造成无法使用，需要对轧棍进行更换，这样会造成资源的大量浪费，而且会使生产成本大幅提高；另外，现有技术中，有个企业通过对轧棍表面进行补料加工，这样质量差，补料附着力低，容易脱落，而且无法一次成型，表面不光滑。After long-term use, the surface of the rolling bar will wear out, which will make it impossible to use. It needs to replace the rolling bar, which will result in a large waste of resources and greatly increase the production cost. In addition, in the prior art, there is a company. By feeding the surface of the rolling bar, the quality is poor, the feeding force is low, and it is easy to fall off, and the molding cannot be performed at one time, and the surface is not smooth.
发明内容Summary of the invention
针对以上现有技术存在的缺陷，本发明的主要目的在于克服现有技术的不足之处，公开了一种可替换式轧棍，包括轧棍本体、滚套、锁圈和键，其中，所述滚套套装在所述轧棍本体上，所述轧棍本体的所述轧棍基座的两端的边缘设置有第一键槽，在所述滚套的内壁的两端与所述第一键槽的对应位置设置第二键槽，所述第一键槽与所述第二键槽对应后插入所述键，使所述轧棍本体与所述滚套不会相对旋转，在所述轧棍基座两端的端面上设置有一圈凹槽，所述凹槽内设置有螺纹，所述锁圈的一面设置有卡圈，所述卡圈上设置有与所述凹槽的相匹配的螺纹。In view of the deficiencies of the prior art, the main object of the present invention is to overcome the deficiencies of the prior art, and disclose a replaceable rolling bar, including a roll body, a rolling sleeve, a lock ring and a key, wherein The rolling sleeve is set on the rolling rod body, and the edge of the two ends of the rolling rod base of the rolling rod body is provided with a first key groove at both ends of the inner wall of the rolling sleeve and the first key groove Corresponding position is provided with a second keyway, and the first keyway is inserted into the key corresponding to the second keyway, so that the rolling bar body and the rolling sleeve are not relatively rotated, and two of the rolling rod bases are A ring groove is disposed on the end surface of the end, the groove is provided with a thread, and one side of the lock ring is provided with a collar, and the collar is provided with a matching thread with the groove.
进一步地，在所述锁圈的内圈设置为锯齿，在所述轧棍基座的端面上设置有锁块，所述锁块通过扭转弹簧与所述轧棍基座旋转固定，另一端由于扭转弹簧的作用始终与所述锁圈接触。Further, the inner ring of the lock ring is provided as a serration, and a lock block is disposed on an end surface of the base of the roll, the lock block is fixedly rotated and fixed to the base of the roll by a torsion spring, and the other end is The action of the torsion spring is always in contact with the lock ring.
进一步地，所述锁圈的边缘在直径方向处于所述滚套的内壁和外壁之间。 Further, the edge of the lock ring is diametrically between the inner wall and the outer wall of the sleeve.
