Abstract
The utility model relates to a belt tensioning mechanism, in particular to a tapping machine belt tensioning mechanism, which comprises a stand column, a motor, a driving cone pulley, a belt and a driven cone pulley, wherein the driving cone pulley is arranged on a main shaft of the motor, the driving cone pulley is linked with the driven cone pulley through the belt, at least two horizontal positioning holes are orderly arranged on one side of the stand column from top to bottom along an axle wire, the side surface of the motor is fixedly connected with a motor mounting seat, at least two positioning shafts are arranged on the side surface of the motor mounting seat, the positioning shafts and the horizontal positioning holes are matched in a sliding mode, a plurality of screw holes which are communicated with the horizontal positioning holes are arranged on the front surface of the stand column, and fastened screws are arranged in the screw holes, and are used to fix the positioning shafts. The tapping machine belt tensioning mechanism is simple in structure and low in cost. The tapping machine belt tensioning mechanism can tension a belt at any time after the belt looses, and is convenient to operate, thereby preventing transmission efficiency to reduce, and being capable of being widely applied in various drilling machines.
Description
Technical field
The utility model relates to a kind of belt tensioning mechanism, especially relates to a kind of tapping machine belt tensioning mechanism.
Background technology
Tapping machine comprises the parts such as base, column, headstock, motor, main shaft, rack sleeve, drill chuck, transmission mechanism and electric switch.Its kind of drive is: motor drives driving cone pulley, belt, driven cone pulley, main shaft and drill chuck rotation successively.Tradition tapping machine is generally without belt tensioning mechanism.After belt slack, will cause transmission efficiency to decline.Also the tapping machine having is with belt tensioning mechanism.But its structure is often too complicated, and production cost is high, and it is also convenient not to operate.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of belt tensioning mechanism of tapping machine, and it is simple in structure, easy to operate, tensioning at any time after belt slack.
The technical scheme that the utility model adopts is: a kind of tapping machine belt tensioning mechanism, comprise column, motor, driving cone pulley, belt and driven cone pulley, described driving cone pulley is installed on described electric machine main shaft, and described driving cone pulley links by belt and described driven cone pulley; Described column one side has at least two horizontal location holes from top to bottom successively along its axis, the side of described motor and a motor mount are affixed, described motor mount side is provided with at least two locating shafts, described locating shaft and described horizontal location hole are slidably matched, described column front has the screw that a plurality of and described horizontal location hole communicates, in described screw, trip bolt is housed, this trip bolt is for fixing described locating shaft.
Further, described motor mount is a vertical metallic plate, or " L " shape or the " metal framework of [" shape.
During normal work, tighten trip bolt, its front end is propped up to locating shaft, be locked in locating hole, it can not be moved left and right; After driving belt is lax, unclamp trip bolt, with hand, motor is pulled outwardly, by driving belt tensioning, then tighten trip bolt locating shaft is locked, motor is positioned to appropriate location.
Beneficial effect: the utility model is simple in structure, cost is low.After belt slack, tensioning at any time, easy to operate, avoided the decline of transmission efficiency, can be widely used in various drilling machines.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 1. column, 2. motor, 3 driving cone pulleys, 4 belts, 5. driven cone pulley, 6. locating shaft, 7. trip bolt, 8. motor mount.
The specific embodiment
Referring to Fig. 1, as shown in the figure, a kind of tapping machine belt tensioning mechanism, comprises column 1, motor 2, driving cone pulley 3, belt 4 and driven cone pulley 5, and driving cone pulley 3 is installed on motor 2 main shafts, and driving cone pulley 5 is by belt 4 and driven cone pulley 5 interlocks; Column 1 one sides have at least two horizontal location holes from top to bottom successively along its axis, the side of motor 2 and a motor mount 8 are affixed, motor mount 8 sides are provided with at least two locating shafts 6, locating shaft 6 is corresponding with horizontal location hole, motor 2 closely cooperates by locating shaft 6 and horizontal location hole, make it be fixed on column 1 side, and can move left and right along axis, horizontal location hole.Column 1 front has at least two screws that communicate with horizontal location hole, and trip bolt 7 is housed in screw, and trip bolt 7 front ends can push against with locating shaft 6, for stationary positioned axle 6.
Motor mount 8 is vertical metallic plates, can be also " L " shape or " metal framework of [" shape, motor 2 is by bolt or be weldingly fixed on motor mount 8.
During normal work, tighten trip bolt 7, its front end is propped up to locating shaft 6, be locked in locating hole, it can not be moved left and right; After belt 4 is lax, unclamp trip bolt 7, with hand, motor 2 is pulled outwardly, by belt 4 tensionings, then tighten trip bolt 7 locating shaft 6 is locked, motor 2 is positioned to appropriate location.The utility model is simple in structure, and cost is low, after belt slack, and tensioning at any time, easy to operate, avoided the decline of transmission efficiency, can be widely used in various drilling machines.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
