Introduction.

Further development and improvement of mechanical engineering efficiency is possible with a significant increase in the level of automation of the production process.

The improvement of machine-building production occurs as a result of the generalization of experience in using the latest means of production and complex automation of production processes based on the use of industrial robots, automatic vehicles, control and measuring tires, etc.

A flexible production module (GPM) is a GPS, consisting of a unit of technological equipment, equipped with an automated software control device and process automation tools. A special case of GPM is a robotic technological complex (RTC), provided that it can be built into a higher level system.

The use of RTK has the following advantages: it contributes to the wider application of the principles of typing technological processes and operations; provides more flexibility for production systems; reduces the cost of designing and manufacturing equipment for automated production, since RTK can use universal industrial robots mass-launched by industry; RTAs are easily combined with APCS and APCS.

The purpose of this work is to develop RTK based on two mod machines. ZM151F2 with a portal robot and a chain type conveyor for processing a shaft type part.

In addition, it is necessary to calculate the guides of the longitudinal table for wear; calculation of FR hand grasping; spindle calculation; calculation of V-belt transmission of the part rotation drive.

. General part of the project

1.1.Analysis of RTC operating conditions.

The robotic complex (RTC) being developed is designed for the about-work of parts such as shafts using such processing methods as external grinding of smooth and discontinuous cylindrical and end surfaces of bodies of revolution.

The RTC includes: two round grinding machines of the ZM151F2 model, portal type PR of the M20C48.01 model, chain type conveyor, RTC control system (BC).

The robotic complex works as follows. Blanks located on chain conveyor in PS (satellite accessory) and by command of BC are supplied to zone of FR capture by means of cutoff devices. Upon command from the sensor, the robot grabs two blanks in turn and transfers them to the working zone of the mill. Then it lowers the first blank, after which the part is clamped in the centers of the machine and the robot expands the grip to return to the previous position. At the end of processing on the first machine, the robot, at the command of the SU, brings its hand and clamps the part, taking it aside after it is riveted on the machine. Then the second hand is brought in and the second blank is installed in the machine centers. After the hand is withdrawn, the PR moves to the working zone of the second machine and lowers the behind-preparation for further processing. At the end of processing on the second machine, the PR grabs the part, moves it to the satellite of the chain conveyor, after which the satellite with the subsequent blank moves to the zone of capture of the robot. After grabbing the workpiece, the PR moves to the working zone of the first machine and replaces the workpieces, after which the cycle is repeated again.

3.3. Calculation of rolling screw-nut transmission of transverse feed of grinding head.

Introduction.

CNC feed drives shall provide high rigidity, positioning accuracy and minimum insensitivity. This imposes increased requirements on each element of the drive: engine, front-precision links, rolling screw-nut transmission, lead screw supports, etc.

Rolling screw-nut transmission (HGC) is one of the main elements of the feed drives of modern CNC machines. At the stage of HCC transmission design, it is very important not only to select its dimensions, but also to consider possible design options, to choose from these options the optimal one, which has good operational parameters at the lowest cost of materials for production.
