Abstract
The invention discloses a cushioning device for a screw shaft reciprocating mechanism. Two cushioning springs are arranged on two sides of a slide block along the axis of a screw shaft. The two cushioning springs press the slide block in the middle. When the slide block moves to transitional curves for reverse on two ends of the screw shaft, the slide block reduces speed under the opposite acting force applied by a screw shaft slideway; at the same time, a slide body impact the cushioning spring first under inertia force, and the cushioning spring transmit the force to the slide block, thereby greatly reduces the impact of the slide body to slideways of the transitional curves of the screw shaft, prolonging the service life of the screw shaft reciprocating mechanism, and reducing the vibration and noises of machines.
Description
Technical field
The present invention relates to mechanical fields such as farm machinery, textile manufacturing machine, particularly relate to a kind of mechanism that utilizes spring minimizing slide block and slideway to impact at the slideway transition curve place at screw axis two ends.
Background technique
Screw axis reciprocating device is that rotatablely moving of screw axis changed into the mechanism that slide block and slide mass are done linear reciprocating motion.This mechanism is widely used in the winding mechanism of mechanical water rice transplanter, textile manufacturing machine.Because slide block movement is to the slideway transition curve place at screw axis two ends, the rapid change of moving direction makes slide block and transition curve slideway produce bigger impact, and along with the raising of machine works speed, this impact is more obvious.The damping device spring of present existing transplanter seedling box mover is arranged on the two ends of the casing of support helix axle, and the effect of damping spring is to remake by slide mass to use slide block.Because the slide block maximum impact occurs in the jointing place of helix and transition curve, the elastic force of damping spring and stroke are difficult to be provided with, and often cause when slide block does not also move to the position that needs buffering, really form the motion that damping spring hinders slide mass.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of screw axis reciprocating device buffering device is provided.
In order to achieve the above object, the technical solution used in the present invention is: a kind of screw axis reciprocating device buffering device, and it comprises screw axis, left side adjustment screw, slide mass, left buffer casting, left damping spring, left jacking block, slide block, right jacking block, right damping spring, right buffer casting, gland and the right screw of adjusting; Wherein, described screw axis passes the slide mass bottom; Slide block is installed in slide mass top, and there is a small column its upper end, and there is a projection lower end, and described projection contacts with the bidirectional screw slideway of screw axis; Slide block and slide mass have left jacking block, left damping spring, left buffer casting, left adjustment screw and right jacking block, right damping spring, right buffer casting, the right side to adjust screw along arranging successively between the both sides of screw axis axial direction; Gland is connected with slide mass, in the middle of the gland elongated slot is arranged, and the small column of described slide block passes this elongated slot.
Further, a described left side is adjusted screw and is fixed on the both sides of slide mass along the screw axis axial direction with the right screw of adjusting by locking nut; Described gland is connected with slide mass by gland screw.
The present invention compares with background technique, and the beneficial effect that has is:
1, at axial direction along screw axis, two damping springs are installed in the both sides of slide block, in the middle of two damping springs are pressed to slide block, when slide block movement during to the commutation transition curve at the two ends of screw axis, slide block is subjected to the bigger opposition of screw axis slideway, its movement velocity descends, and this moment, slide mass impacts damping spring earlier under the effect of inertial force, remake by damping spring and use on the slide block, like this, significantly reduced the impact of slide block, prolonged the working life of spiral mobile mechanism, reduced the vibration and the noise of machine screw axis reverse transition curve slideway.
2, owing to the axial direction along screw axis, damping spring is to be contained between slide block and the slide mass, and two damping springs are tightly clamped slide block, does not exist when slide block does not also move to the position of needs buffering, causes damping spring to hinder the motion of slide mass.

Embodiment
The present invention is further described below in conjunction with drawings and Examples;
Shown in Fig. 1～4, screw axis 1 is installed in slide mass 4 bottoms, slide block 8 is installed in the middle of slide mass 4 tops, slide block 8 has left jacking block 7, left damping spring 6, left buffer casting 5, left side adjustment screw 2 and right jacking block 9, right damping spring 10, right buffer casting 12, the right screw 14 of adjusting successively along the both sides of screw axis direction.Be gland 13 above the slide block 8, the small column on the slide block 8 passes the elongated slot in the middle of the gland 13, and gland 13 is connected with slide mass 4 by gland screw 11, and screw 2 is adjusted on a left side and right the adjustment has the locking nut 3 that prevents that it is loosening on the screw 14.Left side damping spring 6 is clamped by left jacking block 7 and left buffer casting 5 during installation, and right damping spring 10 is clamped by right jacking block 9 and right buffer casting 12, the cushion effect of two damping springs by about adjust screw 2 and 14 controls.Catch bar 16 also is installed in the bottom of slide mass 4, and the shaft axis of its shaft axis and screw axis 1 is on same horizontal line, by Cock screw 15 tightenings.
Screw axis 1 is an axle with bidirectional screw slideway, and when it rotated, slide block 8 drove slide mass 4 and do linear reciprocating motion on screw axis 1.The gland 13 middle elongated slot shapes of opening along the screw axis direction have been shown among Fig. 4, and the small column on slide block 8 tops passes this hole, and making can have bigger relative movement between slide block and the slide mass.Slide block 8 is provided with left damping spring 6 and right damping spring 10 respectively along screw axis direction both sides, and slide block 8 is done toward complex line by these two damping springs promotion slide masses 4 and moved.The buffer level of left side damping spring 6 and right damping spring 10 can be adjusted screw 2 by the left side on the slide mass 4 and adjust with the right screw 14 of adjusting.
