High-stability tool changer rotating indexing mechanism

Abstract

The invention discloses a high-stability tool changer rotating indexing mechanism. The mechanism comprises a substrate; a pair of slide rails is arranged at the bottom of the substrate; a moving seatis arranged between the slide rails; a rotating indexing disc is arranged at the bottom of the moving seat; a tool changer disc is fixed at the bottom of the rotating indexing disc; an indexing inversion mechanism is arranged on the moving seat and drives the rotating indexing disc to rotate; the indexing inversion mechanism comprises a stirring disc which is arranged at the bottom of the moving seat via a rotating shaft; n concave grooves are equidistantly formed in the rotating indexing disc and n > 8; two symmetrically arranged round pins which are engaged with the concave grooves are arranged on the stirring disc; and transition circular arcs are formed in the outer end parts of the concave grooves, so the concave grooves extend outwardly to form modifying grooves. Through the arrangement that the transition circular arcs are formed in the outer end parts of the concave grooves and that the concave grooves extend outwardly to form modifying grooves, the impact load of engagement between the round pins and the concave grooves is effectively lowered, so abrasion is lowered and durability is improved.

Description

technical field [0001] The invention relates to the field of processing and manufacturing, in particular to a high-stability tool magazine rotary indexing mechanism. Background technique [0002] At present, the domestic manufacturing industry is in a critical period of transformation. Accelerating the optimization and upgrading of the manufacturing industry, promoting the transformation from Made in China to Created in China, the transformation from China's speed to China's quality, and the transformation from a manufacturing power to a manufacturing power have been more proposed. The CNC machining center is the mainstream and popular equipment in the contemporary manufacturing industry. Its biggest feature is that it has the function of tool storage and automatic tool change, and this function is mainly realized by the tool magazine and automatic tool change device. The tool magazine and automatic tool changer are important components and key functional components of the m...

Problems solved by technology

[0004] Among them, the single-head double-lead worm gear and worm mechanism can adjust the transmission clearance of the worm gear and worm at any time during use to achieve accurate indexing, but this transmission mechanism is more complicated, and the processing of the single-head double-lead worm gear and worm is more difficult and costly. Relatively; the dual-lead cylindrical cam indexing mechanism has strong bearing capacity and stable indexing and indexing, which is suitable for indexing and indexing mechanisms with large loads, but at the same time, there are also complex mechanisms, difficult processing and relatively high costs. Disadvantages, the sheave mechanism has high rotation efficiency, relatively stable operation, simple structure, and is easy to manufacture. However, the existing pin sheave mechanism requires locking arcs for positioning to perform intermittent movements. A large impact load will still be generated when entering the wheel groove engagement once, which will cause the locking arc to be easily worn or deformed, and the durability will be greatly reduced, and further improvement is required
