Abstract

The utility model relates to the technical field of mechanical engineering, in particular to a reciprocating intermittent motion mechanism. The reciprocating intermittent motion mechanism comprises a shaft lever, a baffle, a spring I, a casing, a slider, a ring-shaped sleeve, a cuboid flat plate, a guide plate, a propulsion pipe, a wedge-shaped blocking block, a spring II, a groove body, a blocking head, a propulsion rod, a retainer ring I, a blocking piece, a retainer ring II and a standing valve. When the propulsion pipe is stressed and acts on the slider, the propulsion pipe forces down the spring I and simultaneously drives the propulsion rod connected with the propulsion pipe and the blocking head to move, the propulsion rod and the blocking head contact with the retainer ring I when moving to the blocking piece, the wedge-shaped blocking block can be pushed out from the groove body to clamp the slider, the spring I is compressed, and then an opposite acting force can generate so as to enable the slider to move in the opposite direction, and the propulsion pipe drives the propulsion rod and the blocking head to move in the opposite direction, and the propulsion rod and the blocking head contact with the retainer ring II when moving to the blocking piece, the blocking head has no force act on the wedge-shaped blocking block, the operation is restored, and then the first reciprocating intermittent motion is accomplished. The reciprocating intermittent motion mechanism has the benefits of being multiple in functions, compact and simple in structure, small in volume and convenient for maintenance.

Description

A kind of intermittent reciprocating motion

Technical field

The utility model relates to mechanical engineering technical field, is specifically related to a kind of intermittent reciprocating motion.

Background technique

In recent years, the intermittent reciprocating motion has obtained utilization widely in many automatic productions field, as IT product, automobile, household electric appliance etc., along with being on the increase of product category on the automatic line, and people are for the raising of quality of product requirement, functional requirement to the intermittent reciprocating motion also increases accordingly, because the function of at present common intermittent reciprocating motion is comparatively single, and because its device proper complex structure, the danger that operation period can break down, therefore the increase of price and maintenance cost, can not better meet people's needs.

Summary of the invention

The purpose of this utility model is to provide a kind of intermittent reciprocating motion at above problem, with solving the problem that existing intermittent reciprocating motion function singleness, device proper complex structure, easy break-down, price and maintenance cost increase.

A kind of intermittent reciprocating motion of the utility model is by axostylus axostyle 1, baffle plate 2, spring I 3, housing 4, slider 5, annular cover 6, cuboid flat board 7, guide rod 8, propulsion tube 9, wedge shape barrier blocks 10, spring II 11, cell body 12, retaining 13, push rod 14, back-up ring I 15, catch 16, back-up ring II 17, standing valve 18 is formed, it is characterized in that: axostylus axostyle 1 passes baffle plate 2 and is fixed by it, and extend to and run through annular cover 6, in propulsion tube 9 and the housing 4 that baffle plate 2 is fixedlyed connected, spring I 3 around housing 4 is set between baffle plate 2 and annular cover 6, and one end and baffle plate 2 are fixing; Have cell body 12 at annular cover 6 and corresponding shell 4 places, mounting spring II 11 in the corresponding shell 4 two ends is fixed a wedge shape barrier blocks 10 corresponding cell bodies 12 bore places respectively in the spring II about in the of 11 with it; Push rod 14 is connected with the standing valve 18 that is positioned at propulsion tube 9 inside, it is fixed with retaining 13 foremost and is the T word shape with it and connects, center fixed has catch 16, extends between two wedge shape barrier blocks 10 by back-up ring I 15, the back-up ring II 17 that is fixed in the housing 4.

The cuboid dull and stereotyped 7 that described slider 5 comprises annular cover 6, fixedly connected with it and be fixed in the symmetrical guide rod 8 in cuboid flat board 7 both sides.

Described catch 16 is between back-up ring I 15, back-up ring II 17.

The cardinal principle of a kind of intermittent reciprocating motion of the utility model is: it utilizes propulsion tube 9 stressed and to slider 5 actings, realize mobile push rod 14 in the time of pressure spring I 3, retaining 13, wedge shape barrier blocks 10 is ejected cell body 12 to be blocked slider 5 and rests then, because spring I 3 is compressed, so produce opposite effect power, make slider 5 towards opposite direction motion, propulsion tube 9 drives push rod 14 simultaneously, retaining 13 an also motion in the opposite direction, therefore unable to wedge shape barrier blocks 10 effect, it is restored to the original state, finish the process of intermittent movement and so forth.

The beneficial effect of a kind of intermittent reciprocating motion of the utility model: diverse in function, compact structure, simple, volume is little, be convenient to safeguard.

Among the figure: axostylus axostyle 1, baffle plate 2, spring I 3, housing 4, slider 5, annular cover 6, cuboid flat board 7, guide rod 8, propulsion tube 9, wedge shape barrier blocks 10, spring II 11, cell body 12, retaining 13, push rod 14, back-up ring I 15, catch 16, back-up ring II 17, standing valve 18 are formed

Embodiment

Example 1.

The utility model relates to mechanical engineering technical field, be specifically related to a kind of intermittent reciprocating motion, by axostylus axostyle 1, baffle plate 2, spring I 3, housing 4, slider 5, annular cover 6, cuboid flat board 7, guide rod 8, propulsion tube 9, wedge shape barrier blocks 10, spring II 11, cell body 12, retaining 13, push rod 14, back-up ring I 15, catch 16, back-up ring II 17, standing valve 18 is formed, be specially: stressed and to slider 5 during along housing 4 actings when propulsion tube 9, the spring I 3 that will be connected with slider 5 is depressed, drive simultaneously and its interior push rod 14 that is connected by standing valve 18, retaining 13 motion together, when moving to catch 16 when contacting with back-up ring I 15, wedge shape barrier blocks 10 can be ejected from cell body 12 under the effect of spring II 11, block slider 5, because baffle plate 2 is fixing with spring I 3, when so spring I 3 is compressed, can produce opposite effect power, slider 5 is moved in the opposite direction, propulsion tube 9 drives push rod 14 by standing valve 18 simultaneously, retaining 13 motion in the opposite direction together, when moving to catch 16 when contacting with back-up ring I 17, because the effect that 13 pairs wedge shape barrier blocks of retaining 10 are unable, under the effect of spring II 11, restore to the original state, promptly finish an intermittent reciprocating motion.
