Abstract
The invention provides a synchronous belt tensioning device for a mechanical type AC linkage double-swinging milling head. The synchronous belt tensioning device comprises a first power shaft component and a second power shaft component which are in transmission connection through a synchronous belt; the synchronous belt is tensioned through a tensioning component; the tensioning component comprises a fixed shaft, a belt wheel shaft and a belt wheel; the fixed shaft is fixed on a milling head main body; the belt wheel shaft is eccentrically bushed on the fixed shaft and is fixed on the fixed shaft through a nut; and the belt wheel is rotatably sleeved on the belt wheel shaft through a ball bearing and is tightly pressed on the synchronous belt. The belt wheel shaft is driven to eccentrically rotate by rotating the belt wheel shaft and the axis of the belt wheel is displaced, so that the synchronous belt is tensioned or released and the purpose of adjusting the tension of the synchronous belt is achieved. The synchronous belt tensioning device has a simple structure, convenience in mounting and adjusting and low manufacturing cost.
Description
Technical field
The present invention relates to the driving mechanism technical field of machine tool accessory milling head, especially relate to a kind of synchronous belt tensioning device of mechanical type AC interlock double-pendulum milling head.
Background technique
At present, the inner transmission of mechanical type pivot angle milling head mainly relies on gear transmission and toothed belt transmission, but gear transmission is difficult for adjusting, so mostly adopt toothed belt transmission.While adopting toothed belt transmission, because Timing Belt can be because wearing and tearing and aging generation belt elongate, the defect of distortion in long-term the use, the phenomenon such as cause the not enough generation of tension force of Timing Belt to be skidded, the transfer motion power loss is more.
Summary of the invention
In order to solve the deficiencies in the prior art, the synchronous belt tensioning device that the purpose of this invention is to provide a kind of mechanical type AC interlock double-pendulum milling head, this synchronous belt tensioning device Timing Belt tension force of adjusting simple in structure, convenient, guarantee that the power transmission of double-pendulum milling head is stable, less kinetic equation loss.
In order to achieve the above object, the invention provides a kind of synchronous belt tensioning device of mechanical type AC interlock double-pendulum milling head, it is characterized in that: it comprises the first powered axle assemblies and the second powered axle assemblies connected by toothed belt transmission, described Timing Belt is by tensioner assembly tensioner, and described tensioner assembly comprises:
Stationary axle, it is fixed on the milling head body;
Belt shaft, its eccentric bushing is located on described stationary axle and by nut and is fixed on stationary axle;
Belt wheel, it is socketed in rotationally on described belt shaft by ball bearing and compresses described Timing Belt.
Preferably, be set with successively vertically pad, belt shaft and nut on described stationary axle.
Preferably, described belt shaft axially offer eccentric through-hole, described stationary axle runs through described eccentric through-hole.
More preferably, the axial end portion of described belt shaft is provided with adjustment part, and the cylindrical of described adjustment part is ellipse, and the end of described adjustment part has the adjustment circular hole.
Preferably, the inwall of described belt wheel two ends vertically offer respectively shoulder hole, and described ball bearing is arranged in described shoulder hole.
Owing to adopting technique scheme, the present invention has the following advantages: by the rotation stationary axle, drive the belt shaft eccentric rotary, make the axle center of belt wheel produce displacement, thereby tensioner or loosen Timing Belt reaches the purpose of adjusting Timing Belt tension force; The present invention is simple in structure, install and adjust is convenient, and fabricating cost is lower.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 be in Fig. 1 A-A to sectional drawing.
In accompanying drawing: 1-the first powered axle assemblies, 2-the second Power Component, 3-tensioner assembly, 4-belt wheel, 5-ball bearing, 6-nut, 7-stationary axle, 8-belt shaft, 9-pad, 10-jump ring, 11-Timing Belt.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.
Refer to Fig. 1 and Fig. 2, a kind of synchronous belt tensioning device of mechanical type AC interlock double-pendulum milling head, it comprises the first powered axle assemblies and the second powered axle assemblies be in transmission connection by Timing Belt 11, and Timing Belt 11 is by tensioner assembly 3 tensioners, and tensioner assembly 3 comprises belt wheel 4, ball bearing 5, nut 6, stationary axle 7, belt shaft 8, pad 9, jump ring 10.
Stationary axle 7 is fixed by screws on the milling head body.Be set with successively vertically pad 9, belt shaft 8 and nut 6 on stationary axle 7.Belt shaft 8 eccentric bushings are located on stationary axle 7 and by nut 6 and are fixed on stationary axle 7.Belt shaft 8 axially offer eccentric through-hole, stationary axle 7 runs through described eccentric through-hole rotationally.The axial end portion of described belt shaft 8 is provided with adjustment part, and the cylindrical of described adjustment part is ellipse, and the end of described adjustment part has a plurality of adjustment circular holes, and a plurality of adjustment circular holes are circumferentially spaced apart along adjustment part.Belt wheel 4 is socketed in rotationally on belt shaft 8 by ball bearing 5 and compresses described Timing Belt.The inwall of belt wheel 4 two ends vertically offer respectively shoulder hole, and two ball bearings 5 are separately positioned in described shoulder hole.By the adjusting hole of adjusting belt wheel shaft 8 ends, make belt shaft 8 rotation, thereby make the axle center of belt wheel 4 produce displacement, thereby tensioner or loosen Timing Belt 11 reaches the purpose of the tension force of adjusting Timing Belt 11.
Adopt above-mentioned simple structure, the present invention can be easily regulated the tension force of the transmission Timing Belt of mechanical type AC interlock double-pendulum milling head, guarantees that the transmission between powered axle assemblies is stable, reduces the transfer motion power loss.
