Problems solved by technology

[0003] The overall design of the tool holder is the fixed part module design and the transformation part module design. The existing design scheme, the tool holder box, the electric spindle and its fixed bracket part of the fixed part module have many changes in the transmission parts, and the replacement of parts is poor.

Embodiment

[0032] This design scheme adopts the modular design method, see the schematic diagram of the design process of the power tool post structure image 3 . The overall design of the tool post is a modular design of fixed parts and a modular design of transforming parts, whether it is an eight-station, ten-station, twelve-station, and sixteen-station tool post, the fixed component modules such as the tool post box, the electric spindle and its The fixed part remains unchanged; just by changing the parts of the transforming part module, it can be combined into a power tool holder with different tool positions. For example, the number of sides of the cutter head is 8, 10, 12, 16 and the number of teeth at the end of the rat tooth disc (positioning Sprocket 4, Index Sprocket Gear 5, Mobile Sprocket 6) are two types of 48 and 40. The transmission gear device consists of 3 groups of 6 gears. The power transmission path is: rotor sleeve 22→clutch gear 14→gear Two 12 → gear shaft one 13 →...

Abstract

The invention discloses a star dynamic tool rest structure transformation design scheme and aims to provide a novel technical scheme which is capable of realizing star dynamic tool rest structure transformation design under conditions that part changes are reduced as far as possible and only a small quantity of transmission parts need to be replaced. An integral tool rest design includes fixing part module design and transformation part module design. Without changing of a tool rest box, an electric spindle and other fixed support parts of a fixing part module, combination of dynamic tool rests different in tool position number can be realized only through changing of tooth numbers of a tooth disc end and two gears in parts of a transformation part module. The combined dynamic tool rests different in tool position number can all realize that a cutter disc rotates by one station while the electric spindle rotates by one turn, and subsequent numerical-control machine tool design is facilitated.

Description

Technical field [0001] The invention relates to a design method of a series of powered tool holders for turning centers. Background technique [0002] The power tool post is a key functional component of the turning machining center, and is known as the development direction of CNC machine tools in the 21st century. Only when the CNC lathe is equipped with a power tool holder can the intensive processing of parts be realized, that is, the compound processing of parts such as turning, milling, drilling, tapping, boring, and reaming can be realized in one clamping. One of its advantages is to significantly improve the processing accuracy of complex parts; the other is to reduce the tedious and repetitive manual operation, and reduce the labor intensity and tension of the operator. With the advancement of technology and the reduction of manufacturing technology costs, turning machining centers equipped with power tool holders with different tool positions and different installation...
