Description
Technical field
The utility model relates to transmission art field, particularly relates to a kind of machine tool chief axis belt tensioning mechanism.
Background technique
Belt transmission is application one of kind of drive extremely widely in the middle of machinery, when distance particularly between axis is distant, employing belt transmission is convenient, because the material price manufacturing belt is low, and this body structure of belt is simple, easy processing, so adopt belt transmission can save a lot of resource, but belt is the part be made up of flexible material, can deform after using a period of time, the tensioning mechanism therefore designing a kind of belt between two axles of V belt translation is necessary.
Model utility content
The purpose of this utility model is exactly the defect in order to overcome prior art, devise a kind of machine tool chief axis belt tensioning mechanism, protection apron adopts thickness of slab to be the sheet metal of 8mm, can work as auxiliary working platform and use, eliminate traditional enclosed motor protective housing, motor radiating is fast.
The required technical problem solved of the utility model can be achieved through the following technical solutions:
A kind of machine tool chief axis belt tensioning mechanism, comprise primary shaft belt pulley, main shaft, belt, electrical machine belt pulley, motor mounting plate, motor, position-adjustable lock screw, socket head screw, setting sleeve, primary shaft belt pulley is connected with machine tool chief axis by flat key, by belt connection for transmission between primary shaft belt pulley and electrical machine belt pulley, motor is screwed on motor mounting plate.
Be provided with position-adjustable lock screw after described motor, position-adjustable lock screw screws in motor mounting plate.
Described setting sleeve is enclosed within outside motor mounting plate, and adopt socket head screw fastening, after unclamping position-adjustable lock screw, motor mounting plate can rotate around setting sleeve, can realize belt and unclamp fast or tensioning.
Owing to have employed above technological scheme, the utility model tool has the following advantages:
Adopt the Combination Design of primary shaft belt pulley, main shaft, belt, electrical machine belt pulley, motor mounting plate, motor, position-adjustable lock screw, socket head screw, setting sleeve, position-adjustable lock screw is provided with after motor, position-adjustable lock screw screws in motor mounting plate, locks or unclamps position-adjustable lock screw and by motor mounting plate locking or can unclamp.Setting sleeve is enclosed within outside motor mounting plate, and adopt socket head screw fastening, after unclamping position-adjustable lock screw, motor mounting plate can rotate around setting sleeve, can realize belt and unclamp fast or tensioning.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model structure;
Fig. 2 is that schematic diagram is looked on the utility model partial structurtes right side;
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
A kind of machine tool chief axis belt tensioning mechanism, comprise primary shaft belt pulley 1, main shaft 2, belt 3, electrical machine belt pulley 4, motor mounting plate 5, motor 6, position-adjustable lock screw 7, socket head screw 8, setting sleeve 9, primary shaft belt pulley 1 is connected with machine tool chief axis 2 by flat key, when primary shaft belt pulley 1 rotates, main shaft 2 plays rotation with one, by belt 3 connection for transmission between primary shaft belt pulley 1 and electrical machine belt pulley 4, motor 6 is screwed on motor mounting plate 5.
Be provided with position-adjustable lock screw 7 after motor 6, position-adjustable lock screw 7 screws in motor mounting plate 5, locks or unclamps position-adjustable lock screw 7 and motor mounting plate 5 can be locked or unclamp.
Setting sleeve 9 is enclosed within outside motor mounting plate 5, and adopt socket head screw 8 fastening, after unclamping position-adjustable lock screw 7, motor mounting plate 5 can rotate around setting sleeve 9, can realize belt and unclamp fast or tensioning.
