Abstract
The invention discloses a grinder belt cradle transmission mechanism. It contains transmission belt, belt wheel groups and headstock rocking body. The belt wheel groups contain zonule wheel and megazone wheel. The transmission belt mounts on zonule wheel and megazone wheel to form a synchronous belt transmission mechanism. The headstock rocking body is equipped in the headstock box and is composed of balance staff support, balance staff, guide wheel, guide wheel shaft, tension spring support and tension spring. The balance staff support is fixed on the balance staff. The headstock shaft is fixed on the balance staff support through headstock support. The tension spring connects with the balance shaft support through tension spring support. The guide wheel is equipped on the guide wheel shaft. The axis of the balance shaft is concentric with that of the zonule wheel. The invention has compact structure and is easy to produce. It improves the rotational stability of the headstock shaft under the rational economy condition and resolves the problem of spindle deformation caused by spindle transmission and belt tension variation during the swing.
Description
Technical field
The present invention relates to a kind of band reel cage transmission mechanism, especially relate to a kind of grinding machine drive mechanism with rocking frame.
Background technology
Industrial, need to use multiple axial workpiece in irregular shape.The difficulty of processing of these parts is very big.With regard to common camshaft, just of a great variety, and different, this type of part of grinding just exists along with the non-circular grinding swing is difficult to stablize the problem of transmission, and traditional solution is to finish transmission by a complex set of mechanical bearing formula universal joint.
The utility model content
The technical problem to be solved in the present invention is that the defective at prior art exists provides a kind of simple in structure, the stable and reliable operation grinding machine drive mechanism with rocking frame.
Technical solution of the present invention is: it comprises driving-belt and belt wheel group, and the headstock waves body, and described belt wheel group comprises small pulley, big belt wheel, and driving-belt is sleeved on the belt wheel group, forms synchronous belt drive mechanism jointly; Being installed on the headstock among the headstock casing waves body and comprises pendulum bearing, balance staff, guide wheel, guide wheel shaft, extension spring bearing, extension spring, described pendulum bearing is fixed on the balance staff, headstock spindle is fixed on the pendulum bearing by headstock bearing, extension spring links to each other with pendulum bearing by the extension spring bearing, and guide wheel is installed on the guide wheel shaft; The axis of described balance staff keeps concentric with the axis of small pulley.
Described driving-belt should be selected synchronous band, many contracts band or cog belt for use, is beneficial to improve transmission accuracy, guarantees that gearratio is accurate.
The present invention adopts tape handler, and driving-belt is by frictional drive, for the main shaft normal and stable operation provides effective guarantee.
Because the present invention selects one group of big small pulley for use, the reductor axle center of transmission input with wave the axon heart and keep concentric, two center distance of belt wheel that transmit to rotate are with to wave body identical to the centre-to-centre spacing of rotating spindle, thereby make and wave body driving-belt in the process of waving and do with it with radius all the time and swing, can not change the centre-to-centre spacing of belt wheel, keep the tensile force of driving-belt constant.
The present invention efficiently solves the imitative non-circle contour grinding machine of type headstock spindle in grinding process can not stablize the problem of transmission along with grinding process is swung between headstock spindle and motor; Simple in structure, easy to manufacture, under the situation of economical rationality, improved the stability that headstock spindle rotates as far as possible, solved that in swing process spindle drive and belt tension change and the problem that caused spindle deformation.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is a right view embodiment illustrated in fig. 1.
Among the figure: the 1-decelerator, the 2-small synchronous pulley, the big synchronous pulley of 3-, 4-is with synchronously, the 5-headstock spindle, bearing before the 6-headstock rear support, the 7-headstock, 8-is by grind away plate, 9-pendulum bearing, 10-balance staff, the 11-guide wheel, 12-guide wheel shaft, 13-extension spring bearing, 14-extension spring, 15-headstock casing.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1,2, present embodiment comprises that driving-belt 4 and belt wheel group, the headstock wave body, and described belt wheel group comprises small pulley 2, big belt wheel 3, and driving-belt 4 is sleeved on the belt wheel group that is made of small pulley 2, big belt wheel 3, forms synchronous belt drive mechanism jointly; Being installed on the headstock among the headstock casing 15 waves body and comprises pendulum bearing 9, balance staff 10, guide wheel 11, guide wheel shaft 12, extension spring bearing 13, extension spring 14, described pendulum bearing 9 is fixed on the balance staff 10, headstock spindle 5 by headstock rear support 6, the headstock before bearing 7 be fixed on the pendulum bearing 9, extension spring 14 links to each other with pendulum bearing 9 by extension spring bearing 13, and guide wheel 11 is installed on the guide wheel shaft 12; The axis of balance staff 10 keeps concentric with the axis of small pulley 2.
Described driving-belt 4 is synchronous band, many contracts band or cog belt.
Be installed on the headstock spindle 5 by grind away plate 8, rely on the pulling force of extension spring 14 to lean against the action of finishing the work on the guide wheel 11.
Decelerator 1 drives headstock spindle 5 work by the belt wheel transmission mechanism, and wherein small pulley 2 is driven by decelerator 1, by the big belt wheel 3 of belt wheel 4 transmissions; Big belt wheel 3 drives headstock spindle 5 and rotates, and rotates synchronously by key and headstock spindle 5 by grind away plate 8.
Extension spring bearing 14 is subjected to the pulling force of extension spring 13 and makes by grind away plate 8 and keep contact with guide wheel 11, rotates when headstock main shaft 5 drives by tape handler, leans on grind away plate 8 and workpiece to rotate synchronously.In grinding machine, mainly by finishing copying work by grind away plate 8 and guide wheel 11 relative motions: different with the contact point of guide wheel 11 by the rotation that grind away plate 8 does not stop, it is also different that the headstock waves the residing position of body, meanwhile, the position of wheel grinding processing work is also with difference.
The key of contour grinder band reel cage transmission mechanism is whether the axis of balance staff 10 can keep concentric with the axis of small pulley 2.It is to be that the axis of balance staff 10 is the center according to swinging by certain angle by the lift of grind away plate 8 and shape with same axis that the headstock waves body, that is to say, it is to be the center with balance staff 10 axis that the headstock waves body, is that radius is done circular motion with headstock spindle 5 axis to the distance of balance staff 10 axis.The axis of small pulley 2 is not as concentric with balance staff 10 axis, driving-belt 4 different tensile forces can occur in different positions, not only influence stability of transmission, directly ring the stressing conditions that shadow headstock spindle 5 reaches by grind away plate 8, the machining accuracy of workpiece also just can't be guaranteed.Decelerator 1 axle center that in assembling process, makes the transmission input just small pulley 2 the axle center with wave the axon heart and keep concentric, make two center distance of belt wheel that transmit to rotate and to wave body basic identical to the centre-to-centre spacing assurance of rotating spindle, accomplish to wave body driving-belt in the process of waving and do with it all the time, so just can not change the tensile force of driving-belt with the radius swing.
