Description
Technical field
The invention belongs to stopping means, particularly to the stopping means of a kind of circular motion.
Background technology
At present, the stopping means being applied on turntable includes mechanical position limitation and the spacing two kinds of versions of electrical equipment.
It is spacing that the many employings of mechanical stop limiter are exposed to external impact formula, and spacing scope is within 360 degree.Electrical equipment limits
Position then uses optoelectronic switch, and optoelectronic switch is arranged on relative zero-bit, light barrier zero-bit and optoelectronic switch zero-bit phase
Correspondence, the Numerical Control revolving table position exported by photoelectric encoder, this structure is opened loop control, once light
Electric switch or photoelectric encoder is the most several breaks down, position-limit mechanism will be malfunctioning, thus cause turntable therefore
Barrier.The limit method also having a kind of non-angular scope to limit is in the internally installed conducting slip ring of turntable, which
Installing loaded down with trivial details, and the conducting slip ring volume being installed on inside is less, price is higher, increases turntable cost, because of
This is not without using conducting slip ring during particular/special requirement.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of circular motion stopping means, its structure letter
Single, easy to install.
The present invention solves technical problem and is adopted the technical scheme that: mounting disc is coaxially fixed with turntable, installs
Fixing light barrier on the edge of dish, the optoelectronic switch coordinated with light barrier is fixed on turntable frame, light barrier and light
Electric switch composition photoelectric encoder stopping means, photoelectric encoder stopping means and the halt circuit of described turntable
Electrical connection；Fixing dynamic collision block on described mounting disc lower surface, the quiet collision block coordinated with dynamic collision block is fixed on institute
On the turntable frame stated, dynamic collision block stops with described turntable with quiet collision block composition electricity stopping means, electricity stopping means
Only circuit electrical connection, electricity stopping means collision connection, turntable stops operating；Described quiet collision block include base,
Switch base, collision bead and spring, switch base has little axis hole suitable for reading, is embedded with collision bead, collision bead axis hole internal clearance
Top, lower end has spring, spring to make collision bead expose from the axis hole of switch base, and base and switch base have screw hole,
Screw hole is for being fixed on mounting disc by quiet collision block.
The present invention uses mechanically and electrically device spacing, electrical equipment spacing employing optoelectronic switch and collision bead type power cutoff mechanism phase
In conjunction with, use two-orbit form double-direction control turntable, make control system reach closed loop states, simple installation,
Economical and practical.

Detailed description of the invention
As shown in Figure 1, 2, mounting disc 4 is coaxially fixed with turntable (being not drawn in figure), the limit of mounting disc 4
Along upper fixing light barrier 2, the optoelectronic switch 1 coordinated with light barrier 2 is fixed on turntable frame (being not drawn in figure),
Light barrier 2 and optoelectronic switch 1 form photoelectric encoder stopping means, and photoelectric encoder stopping means is with described
The halt circuit electrical connection of turntable；On described mounting disc 4 lower surface, fixing dynamic collision block 3, joins with dynamic collision block 3
The quiet collision block 5 closed is fixed on described turntable frame, and dynamic collision block 3 and quiet collision block 5 form electricity stopping means,
Electricity stopping means electrically connects with the halt circuit of described turntable, and electricity stopping means collision is connected, and turntable stops turning
Dynamic.
Described quiet collision block 5 includes base 14, switch base 11, collision bead 10 and spring 12, and switch base 11 has
Little axis hole suitable for reading, is embedded with collision bead 10 axis hole internal clearance, and there are spring 12, spring 12 in top, collision bead 10 lower end
Make collision bead 10 expose from the axis hole of switch base 11, base 14 and switch base 11 have screw hole 16, spiral shell
Nail 16 is for being fixed on mounting disc 4 by quiet collision block 5.As shown in Figure 3.
As shown in Figure 4,5.Present invention additionally comprises mechanical stop limiter, mechanical stop limiter include control dish 20,
Position limiting slide block 21 and driving lever 22, control dish 20 is fixed on described turntable frame, control dish 20 has track
Groove 23, the center of circle of rail groove 23 overlaps with the centre of gyration of turntable, and rail groove 23 internal clearance ground is equipped with spacing
Slide block 21, position limiting slide block 21 is fixed driving lever 22, the limited post (being not drawn in figure) coordinated with driving lever 22
It is fixed on turntable.Turntable rotates counterclockwise, and limited post rotates counterclockwise after encountering position limiting slide block 21, promotes
Position limiting slide block 21 is rotated further, until the high order end of rail groove 23, it is impossible to advance, play mechanical position limitation and make
With.Turntable rotate clockwise process with rotate counterclockwise identical.
Difference according to spacing angle can process the rail groove 23 of different central angle.Rail groove 23 can have many
