2.System composition and function:

This device can achieve purely mechanical automatic machining function, there is a variable speed power box to provide two-way transmission power to the equipment, one way power through the opening and closing of the electromagnetic clutch to control the precision indexing head of the four indexing, in the precision indexing head of the workbench installation of four eccentric wheel clamping fixture, in the process of the indexing head indexing the workpiece is automatically fed, by the eccentric wheel clamping mode of clamping the workpiece clamping, the processing of the finished workpiece through the cam rotary handle The workpiece will be loosened by the eccentric wheel clamping fixture through the cam knob to drop the workpiece into the material tray; all the way through the elastic coupling to connect the bevel gear shaft, the bevel gear distributor is divided into two ways of transmission, all the way by the bevel gear, cylindrical cam drive the automatic drilling machine to achieve the function of feeding and retracting the tool; the cylindrical camshaft is mounted with an adjustable disc cam, limit switch device, which can control the working state of the electromagnetic clutch to make the index head work with the automatic drilling machine and automatic marking machine; the other way, the workpiece is automatically fed during the process of indexing of the indexing head. The other way is controlled by double universal coupling, rack and pinion linkage mechanism to control the cone roller clutch of automatic marking machine, and the automatic marking machine is driven by three-phase asynchronous motor to achieve the function of steel mark knocking.
