Abstract

The utility model discloses a cushioning device of a spiral shaft reciprocating mechanism of springs at two sides of a sliding block. In the axial direction of the spiral shaft, the two sides of the sliding block are provided with two buffer springs which press the sliding block inwards. When the sliding block moves to the reversing transition curve at two ends of the spiral shaft, the sliding block is applied by the great reversing acting force of a slideway of the spiral shaft and the velocity of movement of the sliding block is reduced. At the time, a sliding body attacks the buffer springs under the action of the inertia force and acts on the sliding block through the buffer springs, thereby greatly reducing the impact of the sliding block on the reversing transition curve of the spiral shaft, prolonging the service life of the spiral moving mechanism and reducing the vibration and the noise of the machine.

Description

The screw axis reciprocating device buffering device of slide block both sides spring

Technical field

The utility model relates to mechanical fields such as farm machinery, textile manufacturing machine, particularly relates 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.

The model utility content

The purpose of this utility model is at the deficiencies in the prior art, and the screw axis reciprocating device buffering device of a kind of slide block both sides spring is provided.

In order to achieve the above object, the technical solution adopted in the utility model is: the screw axis reciprocating device buffering device of a kind of slide block both sides spring, 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 utility model is compared 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

Below in conjunction with drawings and Examples the utility model is further specified;

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.
