PLC was applied to bearing design - in the mechanical equipment Industrial control -

Bearing is a kind of important modern machinery and equipment parts. Its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of the movement, and guarantee its rotation accuracy.

bearing production generally require the raw material, turning into inner sleeve, coat, bead casting, heat treatment, cutting into a finished product ( Grinding process has a circular grinding, cylindrical grinding, centerless grinding) Specific technological process, assembling finished products, such as process, can refer to below:

process flow diagram is shown in figure 1 bearing

bearing production takes more working procedure, in a longer interval between each working procedure, production line requires bearing handling. When the traditional handling by artificial, not only low efficiency, and labor costs. Field bearing handling line is illustrated below:

according to customer requirements, on site production process automation manipulator handling, MR - with mitsubishi servo system JE- 40 a, PLC controller selection for sea H32S0T host, the host support 4 road 200 k high-speed pulse input, 4 road 200 k high-speed pulse output, support absolute positioning, relative positioning electric origin definition, origin, etc. , meet the needs of the field control triaxial handling line. CPU bring two communications, and can extend the seven modules. To meet customer requirements and system selection.

configuration screen design. Configuration screen is divided into automatic screen, manual screen, servo setting, parameter setting, IO monitor and alarm screen. Were used to monitor and control the bin is ready, the manipulator cylinder in place, X, Y, Z axis limit position monitoring, demagnetization signal feedback, such as cleaning, dry process control monitoring. Pictures are as follows:

PLC program design. Sea main program can block, convenient to program design of 3 axis of origin, 3 axis positioning program, servo parameter Settings, automatic control, manual control and alarm procedure block to write. Reading program is convenient, save debugging time.

8 main program block diagram design process need, need points on the scene of the servo control, used for PLSR instructions to implement sea. The directive deceleration time, servo start-stop smoothly.

origin regression design. The sea is the origin return ZRN instruction, easy to use. Can be back to the origin of the electric and mechanical origin and through external near point signal back to the mechanical origin. Set frequency and near point of origin with pulse frequency channel, executes, will at some frequency as the initial frequency, accelerate to origin point frequency began to move, slow down while approaching the origin to the near point frequency. The use of the instruction software online help write very clear, is clear.
