Abstract
An electric main shaft protecting base is composed of a connecting post, a main shaft installing plate, a motor installing plate, a spring, a motor and an electric induction switch. The main shaft installing plate and the motor installing plate are connected and positioned through the connecting post, the two installing plates are expanded and locked through elastic force of the spring, the motor is installed on the motor installing plate, and a whole machine head is installed on a machine tool through the main shaft installing plate. The electric main shaft protecting base is characterized in that signals of a main shaft are detected through the electric induction switch. The electric main shaft protecting base is suitable for the automation machine tool for fine machining, the lateral force of the main shafts of machine tools in the series is not large, and the machine tools in the series include a burring machine tool, an automatic mold lettering, scribing and chamfering machine tool, a mold special-shaped face polishing machine tool, an automatic welding machine tool and others.
Description
Technical field
The invention belongs to the electronic main shaft of deburring equipment, handware retrofit equipment and welding equipment or the mount pad of welding rifle of the special-shaped aluminium castings such as engine.
Background technology
The main shaft of more existing retrofit lathes is that the hard contact protection of employing is that the moment size colliding after workpiece by lathe head judges whether to take safeguard measure mostly.Due to main shaft and the internal structure of motor complexity of these retrofit lathes, required precision is very high.Slight collision all may produce destructive infringement to the main shaft of lathe and motor.Hard protection adopts collision moment to judge, the accuracy of detection of moment size is not very high, even the phenomenon that will bring like this collision dynamics also not report to the police very greatly.
Summary of the invention
In order to change some above-mentioned shortcomings, the present invention has designed a kind of main tapping of flexibility, in the time of lathe and the improper collision of workpiece generation, makes machine tool chief axis that a certain amount of displacement occur.Cushion most impact force.
Technical scheme of the present invention is: a kind of electronic main shaft protecting seat, formed by joint pin 1, main shaft installing plate 2, motor mounting plate 3, spring 4, motor 5 and electric induction switch 6, connect and positioning spindle installing plate and motor mounting plate by joint pin, by spring by two boards by elastic force by locked its spreading, motor is arranged on motor mounting plate, and whole head is arranged on lathe by main shaft installing plate; It is characterized in that: the signal detection of described main shaft is detected by electric induction switch.
Described when touching workpiece dynamics, lathe is greater than processed safely when stressed, spring is because locked power is inadequate, connecting rod and motor fixing plate are due to the stressed generation sidesway of motor cutter head, electric induction switch is originally relatively to install up and down, now be offset by motor mounting plate below, electric induction switch is offset up and down, and induced signal interrupts.
The present invention, closes thin micro-machined automated machine tool, and the suffered side force of this series machine tool chief axis is not very large, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Known by Fig. 1, a kind of electronic main shaft protecting seat, formed by joint pin 1, main shaft installing plate 2, motor mounting plate 3, spring 4, motor 5 and electric induction switch 6, connect and positioning spindle installing plate and motor mounting plate by joint pin, by spring by two boards by elastic force by locked its spreading, motor is arranged on motor mounting plate, and whole head is arranged on lathe by main shaft installing plate; The signal detection of main shaft is detected by electric induction switch.When touching workpiece dynamics, lathe is greater than processed safely when stressed, spring is because locked power is inadequate, connecting rod and motor fixing plate are due to the stressed generation sidesway of motor cutter head, electric induction switch is originally relatively to install up and down, now be offset by motor mounting plate below, electric induction switch is offset up and down, and induced signal interrupts.Whole lathe stops processing when induced signal interrupts, has played the effect of protection machine tool chief axis.Like this machine tool chief axis stressed be to have certain amount of movement when excessive, cushioned most impulsive contact force, be not very stiff and demanding contact, many with respect to hard contact protection safety.
Claims (2)
1. an electronic main shaft protecting seat, formed by joint pin, main shaft installing plate, motor mounting plate, spring, motor and electric induction switch, connect and positioning spindle installing plate and motor mounting plate by joint pin, by spring by two boards by elastic force by locked its spreading, motor is arranged on motor mounting plate, and whole head is arranged on lathe by main shaft installing plate; It is characterized in that: the signal detection of described main shaft is detected by electric induction switch.
2. the electronic main shaft protecting seat of one according to claim 1; it is characterized in that: described be greater than processed safely when stressed when lathe touches workpiece dynamics; spring is because locked power is inadequate; connecting rod and motor fixing plate are due to the stressed generation sidesway of motor cutter head; electric induction switch is originally relatively to install up and down; now be offset by motor mounting plate below, electric induction switch is offset up and down, and induced signal interrupts.
