Abstract
The utility model discloses a PLC (Programmable Logic Controller) controlled automatic rotary worktable, which comprises a worktable, a positive rotating air valve, a negative rotating air valve, a controller, a piston switch and a control core PLC unit, wherein the worktable is driven by a pneumatic piston cylinder to rotate; the positive rotating air valve and the negative rotating air valve are used for controlling the flow direction of air flow in the piston cylinder; the controller is used for receiving an external control command and displaying the state of the worktable; the position switch is used for detecting the operating position of the rotary worktable; and the control core PLC unit is used for receiving a control signal transmitted by the controller and a position signal transmitted by the position switch, controlling the actions of the positive rotating air valve and the negative rotating air valve according to the control signal and the position signal as well as outputting state information to the controller. The PLC controlled automatic rotary worktable can automatically rotate according to an automatically-set program, thereby meeting the requirement for automatic processing.
Description
Technical field
The utility model relates to a kind of rotary table, and especially a kind of PLC controls automatic rotary table.
Background technology
Rotary table is a device commonly used on the machining equipment, the zone that generally table top of this rotary table is divided at least two retaining elements, its effect is to add man-hour at lathe to being fixed therein a part in the zone, can carry out the material loading and the blanking of part easily in other zones.But general rotary table all is to design in order manually to carry out operation of feeding and discharging, and the spinning movement of workbench needs the operator manually to control with button.When automatic production line carried out operation, this rotary table just can not adapt to the requirement of automatic processing.
The utility model content
Technical problem to be solved in the utility model provides a kind of rotary table that can be rotated automatically, especially a kind of automatic rotary table of PLC control.
For solving the problems of the technologies described above, PLC of the present utility model controls automatic rotary table and comprises workbench by an air rammer cylinder driven rotary, and just commentaries on classics air valve and the counter-rotating air valve of controlling air flow direction in the described piston cylinder, also comprise the controller that receives the external control instruction and show the workbench state; Detect the position switch of described rotary table running position; And control core PLC unit, receive the control signal of described controller transmission and the position signalling that described position switch sends, according to above-mentioned control signal and the described action of just changeing air valve and described counter-rotating air valve of position signalling control, and to described controller output state information.
With respect to prior art, advantage of the present utility model is:
Just changeing the action of air valve and counter-rotating air valve with the PLC unit controls, thereby the stretching out or shrink of the piston rod in the control piston cylinder, and then driven the forward or reverse of rotary table, only the controller in the utility model need be connected with the controller communication of automatic assembly line, just can realize that this PLC controls automatic rotary table and can rotate automatically according to the program that configures automatically, thereby satisfy the requirement of processing automatically.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Figure of description the utility model is further described.
In one embodiment, described PLC controls automatic rotary table and comprises workbench by an air rammer cylinder driven rotary, and just commentaries on classics air valve and the counter-rotating air valve of controlling air flow direction in the described piston cylinder, also comprise the controller that receives the external control instruction and show the workbench state; Detect the position switch of described rotary table running position; And control core PLC unit, receive the control signal of described controller transmission and the position signalling that described position switch sends, according to above-mentioned control signal and the described action of just changeing air valve and described counter-rotating air valve of position signalling control, and to described controller output state information.
Above-mentioned rotary table is divided into two zones of symmetry, and when a zone was in the Working position of lathe, another zone was in the loading and unloading position of lathe.Two zones are symmetrically arranged with a position switch trigger device, non-rotary place is provided with a position switch on rotary table, the status requirement of this position switch is: when some zones are in the loading and unloading position, this position switch just in time with this zone on the position switch trigger device contact.When just changeing that air valve is connected and counter-rotating air valve when closing, the piston rod driven rotary workbench of air rammer cylinder just changes; Otherwise, when just changeing that air valve is closed and the air valve that reverses when connecting, the piston rod driven rotary workbench counter-rotating of air rammer cylinder.Pass to the control signal of PLC unit according to controller, described PLC can control the unit action of just changeing air valve and counter-rotating air valve, thereby piston cylinder driven rotary workbench is just changeed or reverses.The positional information that position switch then provides workbench to be rotated in place to the PLC unit, thus the PLC unit can stop the action of air rammer cylinder according to this positional information.According to described position switch, just change the action and the state of air valve and counter-rotating air valve, PLC can be to being rotated in the forward of controller output services platform, reverse rotation and halted state information.In order to satisfy requirement of the present utility model, described PLC unit preferably has the PLC of at least 6 input points and at least 12 output points.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
