Description

A kind of main shaft detent mechanism that is used for the automatic lathe of processing spanner
Technical field
The utility model relates to a kind of lathe, especially a kind of lathe of processing spanner.
Background technology
Lathe need carry out the car hole with lathe tool to the spanner part in processing spanner, carry out operations such as groove milling with milling cutter, when changing between various operations, just need carry out accurate localization to main shaft, enables stall fast and accurately.Now to a lot of methods of being positioned with of lathe spindle, more general a kind of be to send the pulse enable signal step motor stop by impulse generator, thereby make the main shaft stall; But the shortcoming of this mode at first is that cost is higher, need use impulse generator and stepper motor, also has back, the location of being exactly main shaft may also have inertia, can rotate, and positioning accuracy will be affected like this.
Summary of the invention
At the problems referred to above, the purpose of this utility model be to provide a kind of simple and convenient, cost is lower and the main shaft detent mechanism of the automatic lathe that is used for processing spanner of accurate positioning.
In order to achieve the above object, the technical solution of the utility model is: a kind of main shaft detent mechanism that is used for the automatic lathe of processing spanner, comprise casing, be provided with main shaft in the casing, be fixed with the main shaft centring ring on the main shaft, main shaft centring ring side is provided with locating slot, and main shaft connects motor by belt drive system, and the driven by motor main shaft rotates; The corresponding main shaft centring ring of main shaft one side is provided with positioning cylinder, positioning cylinder is fixed on the casing, cylinder piston rod front end in the positioning cylinder is fixed with locating piece, the cylinder piston rod lower end is fixed with the frizzen that plays motion with one, and first inductive probe and second inductive probe that are provided with along its movement locus are arranged below the frizzen; Cylinder piston rod drives locating piece and snaps in and leave locating slot, and drives the induced signal that frizzen triggers the induced signal of second inductive probe transmission stall motor and triggers first inductive probe transmission starter motor accordingly.
As preferably, described first inductive probe and second inductive probe all are fixed on the installing rack, and installing rack is fixed on the casing of axis system.
As preferably, described positioning cylinder is arranged on the casing outside, and the corresponding positioning cylinder of casing place has and can make locating piece free in and out the through hole of casing.
As preferably, described belt drive system comprises belt pulley, and belt pulley is arranged on rear-end of spindle, and belt pulley connects motor by belt.
Lathe of the present utility model is by installing centring ring on main shaft, the centring ring side is provided with locating slot, promote locating piece by cylinder again and snap in locating slot, inductive switch is responded to when locating piece snaps in locating slot, send induced signal, make the spindle motor stall, thus main shaft location stall.
Main shaft detent mechanism simplicity of design of the present utility model, cost is lower; And accurate positioning, locating piece snaps in locating slot, and main shaft is firmly blocked, and can not make the location inaccurate because of rotator inertia.
