Description

A kind of brief half reciprocating ratchet mechanism

Technical field

The utility model belongs to industrial machine bed technique field, relates to the mechanism that industrial lathe operation control panel realizes two-position function, is specifically related to a kind of brief half reciprocating ratchet mechanism.

Background technique

Modern machine, the operation panel being especially more common in numerical control device mostly is adjustable stationary structure, when operation panel (is called for short " panel ", when will be in position A down together), need hand rotation panel to A point, terminate rear to rotatingshaft mechanical interlocking, make panel be fixed on A point.This structure uses when being suitable only for non-frequent movable panel.

For the utilization of industrialization numerical control device, produce in enormous quantities, fast often, in the applying working condition of frequent movable panel, if still adopt such scheme, in industrialization society now, more and more there is no advantage, certainly will cost be increased, and inefficiency, make the competitive ability of enterprise reduce, be unfavorable for long-run development.Therefore, the brief half reciprocating ratchet mechanism developing a kind of applicable frequent movable panel applying working condition is needed badly.

Summary of the invention

In order to overcome frequent movable panel in above-mentioned prior art applying working condition in there is manual rotation, mechanical interlocking, therefore cause take time and effort, the shortcoming such as inefficiency, the purpose of this utility model is to provide a kind of brief half reciprocating ratchet mechanism, significantly can improve production operation efficiency, and vertical type operation control panel two-position function can be realized, there is structure simple, feature easy to use.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of brief half reciprocating ratchet mechanism, comprise main rotary shaft 5, main rotary shaft 5 connects ratchet 1, ratchet 1 there is shelves point 7, main rotary shaft 5 there is the actuating linkege 3 be connected with panel rotated around it, actuating linkege 3 is fixed with ratchet rotatingshaft 6, ratchet rotatingshaft 6 has the ratchet 2 rotated around it, the outer conflict of ratchet 2 has keep-spring 9, has the trend engaged with the tooth of ratchet 1 under the effect of keep-spring 9.

Have movable disk 4 outside described main rotary shaft 5, movable disk 4 has the saturating groove of arc, shelves point 7 is arranged in this saturating groove.

There is a groove outer of described movable disk 4.

The outer of described ratchet 1 there is a convex body.

Compared with prior art, the utility model overcomes exists manual rotation, mechanical interlocking in the applying working condition of existing frequent movable panel, therefore cause take time and effort, the defect of inefficiency, significantly can improve production operation efficiency, and vertical type operation control panel two-position function can be realized, there is structure simple, feature easy to use.

Fig. 4 is reset mode figure after releasing locking.

Embodiment

Mode of execution of the present utility model is described in detail below in conjunction with drawings and Examples.

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

As Fig. 1, a kind of brief half reciprocating ratchet mechanism, comprise main rotary shaft 5, main rotary shaft 5 connects ratchet 1, ratchet 1 has shelves point 7, and ratchet 1, main rotary shaft 5 and shelves point 7 are rigid unitary part.Main rotary shaft 5 has the actuating linkege 3 be connected with panel rotated around it, actuating linkege 3 and panel (not providing in figure) are rigid unitary part.Actuating linkege 3 is fixed with ratchet rotatingshaft 6, ratchet rotatingshaft 6 has the ratchet 2 rotated around it, the outer conflict of ratchet 2 has keep-spring 9, has the trend engaged with the tooth of ratchet 1 under the effect of keep-spring 9.Have movable disk 4 and Returnning spring 8 outside main rotary shaft 5, movable disk 4 has the saturating groove of arc, shelves point 7 is arranged in this saturating groove.Movable disk 4 to be put in 7 scopes at shelves around main rotary shaft 5 and is rotated.Movable disk 4 has a groove, its effect is after ratchet 2 leaves the hook tooth of ratchet 1, make hook tooth fall in this groove, as Fig. 2 under the effect of keep-spring 9.Ratchet 1 has a convex body, its effect makes ratchet 2 leave movable disk 4 after falling together with movable disk 4 when ratchet 2 falls into movable disk groove, thus make movable disk 4 under the effect of Returnning spring 8, get back to home position, as Fig. 3 and Fig. 4.

As shown in Figure 1, this state is original state, and ratchet 1 and ratchet 2 are in engagement, and actuating linkege 3 only has the possibility of clockwise movement relative to ratchet 1, and can not counterclockwise movement.

Pull actuating linkege 3 clockwise, when ratchet 2 leaves ratchet 1 completely, ratchet 2 enters in the groove of movable disk 4, as Fig. 2, the lowest part of this groove a little more than hook tooth top, now actuating linkege 3, ratchet 2 and movable disk 4 can together with rotate counterclockwise relative to ratchet 1.When move to as shown in Figure 3 position time, due on ratchet 1 convex body exist cause, ratchet 2 leaves movable disk groove, and now, movable disk 4 gets back to initial position under the effect of Returnning spring 8, as shown in Figure 4.When pulling actuating linkege 3 again, whole system gets back to again initial position as shown in Figure 1.

More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
