Abstract

The invention discloses a Z-axis feeding transmission system structure of a feeding mechanism of a turret milling machine with an interpolation function. A double-row radial-thrust ball bearing and anend cover are arranged in the middle of a lifting platform, a second end cover is fixed in the middle of the lifting platform through a second socket head cap screw, a support is arranged in the middle of the lifting platform, and a second nut is arranged on the support; the second nut is fixed to the support through the second socket head cap screw, and a common flat key and a large gear are arranged at the upper end of a vertical lead screw; the large gear is fixed to the upper end of the vertical lead screw through a cushion and a hexagon nut, and a stepping motor is arranged in the middleof the lifting platform; and a small gear is arranged on an output shaft of the stepping motor, and the small gear is meshed with the large gear. The structure is compact and simple, low in weight, convenient to assemble, reliable in function, low in failure rate, low in manufacturing cost, concise and attractive in appearance and convenient to operate, manual and automatic combined transformation is achieved, a belt wheel can be omitted during manual operation, the motor is installed in equipment, the appearance is simple and attractive, and the structure is applied to the machining industry.

Description

technical field [0001] The invention relates to a Z-axis feed transmission system structure of a turret milling machine feed mechanism with an interpolation function in the mechanical processing industry, in particular to a Z-axis of a turret milling machine feed mechanism capable of realizing interpolation movement of plane milling The structure of the feed transmission system, especially when used in turret milling X-axis and Y-axis milling parts, can realize three-dimensional interpolation processing. In addition, it can also expand the processing range of Z-axis. Background technique [0002] At present, in the mechanical processing industry, the lifting table of ordinary milling machines can only be adjusted manually, and cannot be moved quickly and advanced, let alone participate in interpolation processing. In actual production, it is sometimes necessary for the lifting platform, that is, the Z-axis to have the function of fast-moving-working, manual or automatic, and...

Problems solved by technology

[0006] The purpose of the present invention is to provide a Z-axis feed transmission system structure with the interpolation function of the feed mechanism of the turret milling machine. Disadvantages, the invention can realize manual, automatic and interpolation processing of the lifting table. The mechanical deceleration mechanism is set up, so the torque is increased, and the power of the motor can be reduced, so the mechanism saves energy and takes up little space, because The hand wheel is directly installed on the lead screw. If the user does not need motorized feed, it is only necessary to install no motor during manufacture, so the manufacture is more convenient. The milling machine using this feed mechanism can realize both position adjustment and manual feed. Processing and motorized feed processing, used in conjunction with X coordinates and Y coordinates, can realize interpolation processing of three-dimensional milling processing. This structure is the same as some parts of the structure of the X-axis feed transmission system and the structure of the Y-axis feed transmission system. , parts can be interchanged, so it is more convenient to organize production and maintenance
