Worm machining device

Abstract

The invention provides a worm machining device. The worm machining device is used for machining a blank (1) into a worm, and comprises a movement mechanism, a base (91), an upright column (92), a milling cutter rotating driving motor (93) and a milling cutter (94); the movement mechanism is fixed on the base (91); the lower end of the upright column (92) is fixedly connected with the base (91); the milling cutter rotating driving motor (93) is mounted on the upper end of the upright column (92) and used for driving the milling cutter (94) to rotate; the milling cutter (94) is mounted on the milling cutter rotating driving motor (93) and used for cutting the blank (1); the movement mechanism comprises a blank carrying piece (2), a sleeve (3) with external threads, a driving sleeve (4) with internal threads and a frame (7).

Description

technical field [0001] The present application relates to the field of worm machining, in particular to a worm machining device. 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 multi-stage transmission, so the worm ...

Problems solved by technology

4. The efficiency of worm transmission is low. It is generally believed that the efficiency of worm transmission is lower than that of gear transmission.

However, the shape processing and manufacturing of the worm gear tooth profile is troublesome, and it is difficult to ensure the accuracy of the processed tooth groove shape and position

[0003] In particular, in some specific application areas, such as soft materials (such as plastics) processing, traditional metal processing methods will be difficult to meet the requirements of reducing costs and improving processing speed and accuracy
