Abstract

The invention discloses a worm machining mechanism capable of automatically performing up-down limiting. The worm machining mechanism is used for machining a blank (1) into a worm and comprises a blank bearing member (2), a sleeve (3) with external thread, a driving sleeve (4) with internal thread and a rack (7), wherein the blank bearing member (2) is used for bearing the blank (1); the upper and lower ends of the blank bearing member (2) are axially and fixedly arranged in the sleeve (3) with the external thread relative to the sleeve (3) with the external thread through an upper bearing (21) and a lower bearing (22) respectively; the sleeve (3) with the external thread is matched in the driving sleeve (4) with the internal thread; the lower end of the driving sleeve (4) with the internal thread is arranged on the rack (7) through a thrust bearing (47) in a rotating manner.

Description

technical field [0001] The application relates to the field of worm machining, in particular to a worm machining mechanism capable of automatic upper and lower limit. Background technique [0002] The worm drive is composed of a worm and a worm gear, and the worm is generally the active part. Worms, like threads, can be divided into right-handed and left-handed. Worm drive has the following advantages: 1. Large transmission ratio and compact structure. The number of worm heads is represented by Z1 (generally Z1=1~4), and the number of worm gear teeth is represented by Z2. It can be seen from the transmission ratio formula I=Z2 / Z1 that when Z1=1, that is, the worm is single-headed, and the worm must turn Z2 to turn the worm wheel for one turn, so a large transmission ratio can be obtained. Generally, in power transmission, take The transmission ratio I=10-80; in the indexing mechanism, I can reach 1000. Such a large transmission, such as gear transmission, needs to adopt ...
