Abstract

The utility model discloses a novel pneumatic mechanical paw. The novel pneumatic mechanical paw comprises a fixing plate, fingers, a guide mechanism and a pneumatic cylinder, wherein the fingers are arranged on the fixing plate; the lower ends of connecting plates in the guide mechanism are fixed on the fixing plate through tightening screws; a rack is embedded in the middle of the fixing plate; a telescopic shaft of the pneumatic cylinder is connected with the rack in the fixing plate; one end of each finger has a circular hole; sliding sleeves are arranged in the circular holes; central shafts penetrate through the circular holes and are used for connecting the fingers with the fixing plate; outer circles which are coaxial to the circular holes are formed at the same ends as those of the central shafts; a plurality of teeth are arranged on the outer circles and are connected with the rack in the fixing plate through a gear rack; the guide mechanism comprises the connecting plates, an upper guide plate and a lower guide plate; the middle parts and the two ends of the upper guide plate and the lower guide plate have a hole respectively; the middle holes are provided with a fixing cylinder respectively; and the connecting plates penetrate through the holes at the two ends and are connected with the upper guide plate and the lower guide plate. According to the novel pneumatic mechanical paw, workpieces are tightened and loosened by a mechanical principle; and the mechanical paw is automatically and mechanically produced, saves time and labor, has a simple structure and is convenient to use.

Description

A kind of novel pneumatic mechanical paw

Technical field

This is novel to relate to a kind of mechanical device, relates in particular to a kind of novel pneumatic mechanical paw.

Background technology

In the industry, the mechanization of production process and automation have become outstanding theme in modern times, and in machining and injection moulding processing industry, a lot of stations are the work of picking up of object; The general action of this operation is simple, with low content of technology, and even is difficult to find the operator, because repeatability is big; So the employing manipulator addresses that need at present, designed and much picked up manipulator; Comprise that surge, pneumatic and electronic etc., but the front end of present this machinery or machinery picks up part, i.e. paw section; Complex structure is made difficulty mostly, and cost is very high and range of application is limited.

Novel content

This novel purpose is exactly in order to address the above problem, and a kind of novel pneumatic mechanical paw is provided, and it has simple in structure, advantage easy to use.

To achieve these goals, the following technical scheme of this novel employing:

A kind of novel pneumatic mechanical paw; Comprise fixed head, finger, guiding mechanism, pneumatic cylinder, finger mounted is on fixed head, and the connecting plate lower end in the said guiding mechanism is fixed on fixed head through trip bolt; Fixed head middle part embeds tooth bar, and the pneumatic cylinder telescopic shaft is connected with tooth bar in the fixed head.

Point an end and be provided with circular hole, sliding sleeve is installed in the circular hole, axle is passed circular hole and will point with fixed head and be connected, holds together to be provided with the cylindrical coaxial with circular hole, and said cylindrical is provided with plurality of teeth, and tooth is that rack-and-pinion is connected with the interior tooth bar of fixed head.

Guiding mechanism comprises connecting plate, goes up guide plate and lower guide plate, and in the middle of last guide plate and the lower guide plate and two ends are respectively equipped with the hole, and fixed cylinder all is housed on the interstitial hole, and the hole that connecting plate passes two ends is connected with lower guide plate with last guide plate.

Pneumatic cylinder is installed in the fixed cylinder on guide plate and the lower guide plate.

The beneficial effect that this is novel:

This novel theory of mechanics of utilizing, completion steps up and loosens workpiece, is the production automation, mechanization, and is time saving and energy saving, and simple in structure, easy to use.

Description of drawings

Fig. 1 is a novel pneumatic mechanical paw front view;

Fig. 2 is a novel pneumatic mechanical paw left view;

Fig. 3 is novel pneumatic mechanical paw finger cutaway view.

Wherein, 1. finger, 2. sliding sleeve, 3. axle, 4. trip bolt, 5. fixed head, 6. tooth bar, 7. lower guide plate, 8. fixed cylinder, 9. pneumatic cylinder is 10. gone up guide plate, 11. connecting plates.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment to this novel being described further.

Like Fig. 1, Fig. 2, shown in Figure 3, this novel connecting plate 11 is connected with fixed head 5 through trip bolt 4, and pneumatic cylinder 9 is installed in connecting plate 7, goes up in the fixed cylinder 8 of guide plate 10 and lower guide plate 7; Pneumatic cylinder 9 telescopic shafts are connected with tooth bar 6 in the fixed head 5, drive tooth bar 6 and move up and down, and tooth bar 6 is that rack-and-pinion is connected with pointing 1 one ends; Tooth bar 6 drives finger 1 and rotates around axle 3; 2 auxiliary rotary actions of sliding sleeve when pneumatic cylinder moves downward, add clamping of workpieces; When moving upward, loosen workpiece.

Though the above-mentioned accompanying drawing that combines is described this novel specific embodiment; But be not restriction to this novel protected scope; One of ordinary skill in the art should be understood that; On the basis of this novel technical scheme, those skilled in the art need not pay various modifications that creative work can make or distortion still in this novel protection domain.
