Abstract

The invention relates to a circular motion spacing device. A mounting plate and a rotary table are coaxially fixed; the edge of the mounting plate is fixedly provided with a light barrier; an optoelectronic light matched with the light barrier is fixedly arranged on a rotary table frame; the light barrier and the optoelectronic switch form an optoelectronic coder spacing device; the optoelectronic coder spacing device is electrically connected with the stop circuit of the rotary table; the lower end surface of the mounting plate is fixedly provided with moving collision blocks; stationary collision blocks cooperated with the moving collision blocks are fixedly arranged on the rotary table frame; the moving collision blocks and the stationary collision blocks form an electric spacing device; the electric spacing device and the stop circuit of the rotary table are electrically connected; when the electric spacing device is in collision switching, the rotary table stops rotating. The circular motion spacing device has the advantages of simple structure and convenience in use and installation.

Description

Circular motion stop means

Technical field

The invention belongs to stop means, particularly a kind of stop means of circular motion.

Background technology

At present, the stop means be applied on turntable comprises 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 is spacing, uses optoelectronic switch, optoelectronic switch is arranged on relative zero-bit, light barrier zero-bit is corresponding with optoelectronic switch zero-bit, the Numerical Control revolving table position exported by photoelectric encoder, this structure is opened loop control, break down once optoelectronic switch or photoelectric encoder are wherein several, position-limit mechanism will be malfunctioning, thus cause turntable fault.Also have the limit method of a kind of non-angular scope restriction to be install conducting slip ring in turntable inside, which is installed loaded down with trivial details, and it is less to be installed on inner conducting slip ring volume, and price is higher, increases turntable cost, does not therefore use conducting slip ring without during particular/special requirement.

Summary of the invention

In order to overcome the shortcoming of prior art, the invention provides a kind of circular motion stop means, its structure is simple, easy to install.

The technical scheme that technical solution problem of the present invention is taked is: mounting disc and turntable are coaxially fixed, fixed stop mating plate on the edge of mounting disc, the optoelectronic switch coordinated with light barrier is fixed on turntable frame, light barrier and optoelectronic switch form photoelectric encoder stop means, and photoelectric encoder stop means is electrically connected with the halt circuit of described turntable; Fixing dynamic collision block on described mounting disc lower surface, the quiet collision block coordinated with dynamic collision block is fixed on described turntable frame, and dynamic collision block and quiet collision block form electric stop means, and electric stop means is electrically connected with the halt circuit of described turntable, the collision of electricity stop means is connected, and turntable stops operating.

The present invention uses mechanical and electrical equipment is spacing, and the spacing employing optoelectronic switch of electrical equipment combines with collision bead type power cutoff mechanism, adopts two-orbit form double-direction control turntable, makes control system reach closed loop states, simple installation, economical and practical.

Embodiment

As shown in Figure 1, 2, mounting disc 4 and turntable (not shown in FIG.) are coaxially fixed, fixed stop mating plate 2 on the edge of mounting disc 4, the optoelectronic switch 1 coordinated with light barrier 2 is fixed on turntable frame (not shown in FIG.), light barrier 2 and optoelectronic switch 1 form photoelectric encoder stop means, and photoelectric encoder stop means is electrically connected with the halt circuit of described turntable; Fixing dynamic collision block 3 on described mounting disc 4 lower surface, the quiet collision block 5 coordinated with dynamic collision block 3 is fixed on described turntable frame, and dynamic collision block 3 forms electric stop means with quiet collision block 5, and electric stop means is electrically connected with the halt circuit of described turntable, the collision of electricity stop means is connected, and turntable stops operating.

Described quiet collision block 5 comprises base 14, switch base 11, collision bead 10 and spring 12, switch base 11 has upper young axis hole, be embedded with collision bead 10 axis hole internal clearance, there is spring 12 on top, collision bead 10 lower end, spring 12 makes collision bead 10 expose from the axis hole of switch base 11, base 14 and switch base 11 have screw hole 16, and screw hole 16 is for being fixed on mounting disc 5 by quiet collision block 5.As shown in Figure 3.

As shown in Figure 4, Figure 5.The present invention also comprises mechanical stop limiter, mechanical stop limiter comprises console panel 20, position limiting slide block 21 and driving lever 22, console panel 20 is fixed on described turntable frame, console panel 20 there is rail groove 23, the center of circle of rail groove 23 overlaps with the centre of gyration of turntable, position limiting slide block 21 is housed rail groove 23 internal clearance, position limiting slide block 21 is fixed driving lever 22, the limited post (not shown in FIG.) coordinated with driving lever 22 is fixed on turntable.Turntable rotates counterclockwise, and after limited post rotates counterclockwise and encounters position limiting slide block 21, promotes position limiting slide block 21 and is rotated further, until the high order end of rail groove 23, cannot advance, play mechanical position limitation effect.Turntable rotate clockwise process with rotate counterclockwise identical.

The rail groove 23 of different central angle can be processed according to the difference of spacing angle.Rail groove 23 can have many, distributes with one heart.
