Abstract
A spring floating type motor-driven spindle protective seat comprises a connection pillar (1), a spindle installation plate (2), a motor installation plate (3), a spring (4), a motor (5), an electric induction switch (6) and a spindle cutter bit (7), and is characterized in that the electric induction switch (6) detects work signals of the spindle cutter bit (7), the spindle cutter bit (7) is stressed and moves sideway to drive the motor installation plate (3) and the electric induction switch (6) to generate excursion, meanwhile, a signal gives out an instruction to cut off the power source, and a machine tool stops working. According to the spring floating type motor-driven spindle protective seat, when the force of the machine tool acted on a workpiece is larger than the stress of safe machining, the connection pillar and the motor installation plate moves sideway due to the stress of the spindle cutter bit, the electric induction switch shifts up and down, an induction signal is interrupted, and the spindle of the machine tool is protected.
Description
Technical field
The utility model belongs to the electronic main shaft of deburring equipment, handware retrofit equipment and welding equipment of the special-shaped aluminium casting such as engine or the mount pad of welding rifle.Be fit to thin micro-machined automated machine tool, the suffered side force of this series machine tool chief axis is not very large, such as burr removing machine tool, and the automatic die line beveler machine tool of carving characters, die abnormal-shaped mirror polish lathe, automatic welding machine tool etc.
Background technology
The main shaft of more existing retrofit lathes is to adopt hard contact protection (its meaning is to judge whether to take safeguard measure by the moment size that the lathe head collides behind the workpiece) mostly.Because the main shaft of these retrofit lathes and internal structure of motor are complicated, required precision is very high.Slight collision all may produce destructive infringement to main shaft and the motor of lathe.Hard protection adopts collision moment to judge that the accuracy of detection of moment size is not very high, even will bring so the very large phenomenon of also not reporting to the police of collision dynamics.
Summary of the invention
For above shortcoming; the purpose of this utility model is to provide a kind of spring floating formula electronic main shaft protecting seat; it is the main tapping that between joint pin and main tapping, is provided with a kind of flexibility; make when lathe and the improper collision of workpiece generation; machine tool chief axis produces a certain amount of displacement, to cushion most impact force.
The technical solution of the utility model is achieved in the following ways: the electronic main shaft protecting seat of spring floating formula, comprise joint pin, main shaft installing plate, motor mounting plate, spring, motor, electric induction switch and main shaft cutter head, be provided with spring and electric induction switch between joint pin and the main tapping, spring is locked main shaft installing plate and motor mounting plate by the elastic force spreading, motor is installed on the motor mounting plate; It is characterized in that: described electric induction switch detects the working signal of main shaft, the stressed generation sidesway of main shaft cutter head, and drive motor installing plate and electric induction switch are offset up and down, and induced signal interrupts, and synchronous signal sends instruction and cuts off the electricity supply, and lathe quits work.
The utility model structure: when lathe touches the workpiece dynamics when stressed greater than processed safely, joint pin and motor fixing plate are because the stressed generation sidesway of main shaft cutter head, and the electric induction switch is offset up and down, and induced signal interrupts.Whole lathe stops processing when induced signal interrupts, played the effect of protection machine tool chief axis.Like this machine tool chief axis stressed be that certain amount of movement is arranged when excessive, cushioned most impulsive contact force, be not the contact of confronting the tough with toughnees, many with respect to hard contact protection safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after spindle head of lathe is offset.
Among the figure: 1 joint pin, 2 main shaft installing plates, 3 motor mounting plates, 4 springs, 5 motors, 6 electric induction switches.
The specific embodiment
Known by Fig. 1, the electronic main shaft protecting seat of spring floating formula, comprise joint pin 1, main shaft installing plate 2, motor mounting plate 3, spring 4, motor 5 and electric induction switch 6, by spring 4 two main shaft installing plates 2 and motor mounting plate 3 are locked by the elastic force spreading, motor 5 is installed on the motor mounting plate 3, and whole head is installed on the lathe by main shaft installing plate 2; The signal detection of main shaft is detected by electric induction switch 6.
Being known by Fig. 2, is the structural representation after machine tool chief axis cutter head 7 is offset.When lathe touches the workpiece dynamics greater than processed safely after the excessive detent force that surpasses 4 springs and 1 joint pin 1 of stressed or cutting force; cutter will be passed original position by workpiece; the mobile drive motor 5 of cutter moves; again drive motor installing plate 3 displacements of motor 3; when as long as displacement has satisfied electric induction switch 6 cut off value; lathe will stop all runnings immediately, has played the effect of protection machine tool chief axis.Lathe integral body shuts down, and the impact moment head moves, and has played cushioning effect, and lathe shuts down behind the electric induction switch circuit breaking, and the damage to lathe is stopped, and plays a protective role.
Claims (1)
1. the electronic main shaft protecting seat of spring floating formula, comprise joint pin (1), main shaft installing plate (2), motor mounting plate (3), spring (4), motor (5), electric induction switch (6) and main shaft cutter head (7), be provided with spring (4) and electric induction switch (6) between joint pin (1) and the main shaft cutter head (7), spring (4) is locked main shaft installing plate (2) and motor mounting plate (3) by the elastic force spreading, motor (5) is installed on the motor mounting plate (3); It is characterized in that: described electric induction switch (6) detects the working signal of cutter head (7), the stressed generation sidesway of main shaft cutter head (7), drive motor installing plate (3) and electric induction switch (6) skew, synchronous signal sends instruction and cuts off the electricity supply, and lathe quits work.
