Description
Technical field
The present invention relates to a kind of sleeping milling workbench automatic lifting control system.
Background technology
Processing in the process of rock drill YT24-1.09 rifle bar with the sleeping XA6132 that mills, adopt dividing head just differential.Early stage is new because Pulley mechanism and dividing head are, and machining accuracy is higher, and helicla flute flank roughness is good, without chewing phenomenon.But along with increase service time, each position wearing and tearing increases, and has produced driving error, and subject matter is that dividing head does not also begin to turn, and workbench has moved a beat in advance, has caused flank to chew phenomenon, chews about the about 0.15-0.2mm of the degree of depth.Product quality caused had a strong impact on.
Summary of the invention
Technical problem to be solved by this invention is the problem that chews surface of the work in order to overcome workpiece cutter in process, provides a kind of method by withdrawing to solve the sleeping milling workbench automatic lifting control system that chews surface of the work.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of sleeping milling workbench automatic lifting control system, comprise workbench, at workbench worktable lifting leading screw, cylinder are installed, be in transmission connection by linkage between the piston rod of described cylinder and the worktable lifting leading screw, be connected with to control the air-operated solenoid valve of cylinder action on the described cylinder, air-operated solenoid valve is electrically connected with electric control gear.
Below be further improvement of these options of the present invention:
Described electric control gear comprises table feed relay, workbench withdrawing relay, workbench reversing switch, workbench function of auto-lift change-over switch and air-operated solenoid valve coil;
The coil of workbench withdrawing relay is connected between the power supply through the normally-closed contact of workbench reversing switch;
The coil of table feed relay is connected in parallel on the two ends of the coil of workbench withdrawing relay through the normally opened contact of workbench reversing switch;
One end of the coil of table feed relay is connected with the normally opened contact of workbench reversing switch, the other end ground connection of the coil of table feed relay;
The normally opened contact of workbench withdrawing relay is connected between the power supply through the first contact, the air-powered electromagnetic valve coil of workbench function of auto-lift change-over switch;
The normally opened contact of table feed relay is connected between the power supply through the second contact of workbench function of auto-lift change-over switch;
The 3rd contact of workbench function of auto-lift change-over switch is connected between the power supply.
Further improve: the two ends of the 3rd contact of workbench function of auto-lift change-over switch are in series with workbench fast lifting protection switch.
The present invention adopts technique scheme, after hinge arrangement is connected on the leading screw, and two disconnections that are depressed of workbench fast lifting protection switch, worktable lifting is in the hinge state of a control.Closing Switch before the sleeping milling workbench automatic lifting control system work is with air-powered electromagnetic valve coil access main circuit.
When workpiece processes a rear Y-direction withdrawing of station processing, the workbench reversing handle is commutating moment, the contact adhesive is with air-powered electromagnetic valve coil and upper level main circuit UNICOM, the adhesive of air-powered electromagnetic iron, make the air-operated solenoid valve commutation, cylinder piston rod stretches out, and by linkage, rectilinear motion is converted to the gyration of leading screw, be converted to again the decline of workbench Z-direction, withdrawing amount 0.35mm; On the contrary, during feed, the workbench reversing handle is commutating moment, by this workbench automatic lifting system, workbench is raised to the state that processing is set, and reaches the purpose of automatic tool advancing and retracting, thereby reduces the cutter Repeated Cutting and damage the machined surface of workpiece when withdrawing.
The present invention is further described below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the embodiment of the invention;
Accompanying drawing 2 is the side view of accompanying drawing 1;
The circuit diagram of the electric control gear that cylinder stretches in accompanying drawing 3 embodiment of the invention.
Among the figure: the 1-linkage; 2-worktable lifting leading screw; The 3-cylinder; The 4-air-operated solenoid valve; The 5-workbench; KM3-table feed relay and relevant contacts; KM4-workbench withdrawing relay and relevant contacts; ZH1-workbench function of auto-lift change-over switch; 1C1-air-powered electromagnetic valve coil; SQ8-workbench fast lifting protection switch; SQ9-workbench reversing handle.
The specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of sleeping milling workbench automatic lifting control system, comprise workbench 5, at workbench 5 worktable lifting leading screw 2, cylinder 3 are installed, be in transmission connection by linkage 1 between the piston rod of described cylinder 3 and the worktable lifting leading screw 2, be connected with to control the air-operated solenoid valve 4 of cylinder 3 actions on the described cylinder 3, air-operated solenoid valve 4 is electrically connected with electric control gear.
As shown in Figure 3, described electric control gear comprises table feed relay K M3, workbench withdrawing relay K M4, workbench reversing switch SQ9, workbench function of auto-lift change-over switch ZH1 and air-operated solenoid valve coil 1C1, the coil of workbench withdrawing relay K M4 is connected between the power supply through the normally-closed contact B of workbench reversing switch SQ9, the coil of table feed relay K M3 is connected in parallel on the two ends of the coil of workbench withdrawing relay K M4 through the normally opened contact A of workbench reversing switch SQ9, one end of the coil of table feed relay K M3 is connected with the normally opened contact A of workbench reversing switch SQ9, the other end ground connection of the coil of table feed relay K M3;
The normally opened contact A of workbench withdrawing relay K M4 is connected between the power supply through the first contact, the air-powered electromagnetic valve coil of workbench function of auto-lift change-over switch ZH1;
The normally opened contact A of table feed relay K M3 is connected between the power supply through the second contact of workbench function of auto-lift change-over switch ZH1;
The 3rd contact of workbench function of auto-lift change-over switch ZH1 is connected between the power supply, and the two ends of the 3rd contact of workbench function of auto-lift change-over switch ZH1 are in series with workbench fast lifting protection switch SQ8.
