The utility model content
The purpose of this utility model will overcome epipodium exactly, and provide a kind of can be according to the variation of abrasive band girth and respective change in when work, thereby make the abrasive band when work, be in tensioning state all the time, prolong the service life in abrasive band, change convenient, the easy amary tape grinding machine automatic takeup in abrasive band.
In order to achieve the above object, technical solution of the present utility model is: the amary tape grinding machine automatic takeup comprises casing, driving wheel, follower, tensioning support, abrasive band, tensioning shaft, eccentric shaft and tensioning spring; This tensioning shaft passes the relative both sides of connect box, and the position, intermediate portion is set with tensioning spring; The left end of this tensioning shaft is a splined shaft, and above-mentioned splined shaft matches with spline housing on being fixed on casing; The right-hand member of this tensioning shaft is connected with the tensioning support that follower is installed; This eccentric shaft vertically passes the manhole that tensioning shaft is provided with, and above-mentioned manhole matches with the eccentric part that eccentric shaft is provided with.
One end of described tensioning spring leans against on the medial surface in casing left side, and the other end of this tensioning spring is by fixed cover and straight pin latched position.
The eccentric throw of described eccentric shaft is 6mm.The outer end of described eccentric shaft is provided with through hole.
The rotating shaft of described follower is installed on the tensioning support by two set bolts, and the central axis and the tensioning shaft of this follower are perpendicular.
Lock in the through hole that the right-hand member insertion tensioning support of described tensioning shaft is provided with and by straight pin.
Compared with the prior art the utility model has the following advantages and good effect:
(1) can be during this device busy and respective change according to the variation of abrasive band girth, make the abrasive band be in tensioning state all the time, thereby guarantee that the sample that processes reaches user's quality requirement, also correspondingly prolonged the service life in abrasive band, and it is convenient, easy to change the abrasive band.
(2) locked position of this device is unique, and when eccentric bushing closely contacted with tensioning shaft, the abrasive band was in relaxed state, at this moment can change the abrasive band, otherwise the abrasive band was in tensioning state, but its tensioning state changes, and a plurality of positions are arranged.
Description of drawings
Fig. 1 is a main pseudosection of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, driving wheel; 2, spline housing; 3, tensioning shaft; 4, casing; 5, tensioning spring; 6, fixed cover; 7, straight pin; 8, eccentric shaft; 9, abrasive band; 10, straight pin; 11, follower; 12, rotating shaft; 13, tensioning support; 14, set bolt; 15, motor; 16, set bolt; 8-1, through hole.
The specific embodiment
As depicted in figs. 1 and 2, the utility model amary tape grinding machine automatic takeup comprises casing 4, driving wheel 1, follower 11, tensioning support 13, abrasive band 9, tensioning shaft 3, eccentric shaft 8 and tensioning spring 5; Wherein said tensioning shaft 3 is horizontally through two installing holes that casing 4 left and right sides are oppositely arranged, and in the intermediate sleeve of tensioning shaft tensioning spring 5 is housed; One end of this tensioning spring leans against on the medial surface in casing left side, and its other end is by fixed cover 6 and straight pin 7 latched positions.
The right-hand member of described tensioning shaft 3 is a plug, in the through hole that above-mentioned plug insertion tensioning support 13 is provided with and by straight pin 10 latched positions; The left end of this tensioning shaft 3 is a splined shaft, and above-mentioned splined shaft matches with spline housing 2, and this spline housing is fixed on the lateral surface in casing left side.The structure that adopts splined shaft to match with spline housing is in order to realize accurate guiding, guarantee that tensioning shaft can not rotate when to move axially.
Described eccentric shaft 8 vertically passes the manhole that tensioning shaft 3 is provided with, and above-mentioned manhole matches with the eccentric part that eccentric shaft is provided with; The eccentric throw of this eccentric shaft is 6mm.This tensioning shaft 3 is perpendicular with eccentric shaft 8, is provided with the through hole 8-1 that is used to install handle in the outer end of eccentric shaft 8; Come rotation eccentric axis by handle, be convenient to finish the tensioning and the replacing in abrasive band.
Described driving wheel 1 is installed on the output shaft of motor 15 by set bolt 16 and flat key, and motor is installed on the base.The rotating shaft 12 of follower 11 is installed on the tensioning support 13 by two set bolts 14, and the central axis of this follower and tensioning shaft 3 are perpendicular.
