Description

A kind of belt stretcher
Technical field:
The utility model relates to the machine tool technology field, is specifically related to a kind of belt stretcher.
Background technique:
In mechanical processing industry, the tensioning mode of lathe belt has a variety of: the eccentric wheel belt tension is arranged, electric motor plate rotation tensioning is arranged, middle transition wheel compressing tensioning is arranged, eccentric cam interlock tensioning etc. is arranged
These tension device generally need a plurality of part combinations, complex structure, profile is huger, cost is higher, adjustment range is little, it is more bothersome to install, generally can not accomplish general, under these circumstances, because the characteristic of this equipment just can't be used in general factory, and a large amount of money has so not only been wasted in also maintenance that can't be good, has also wasted a large amount of time and manpower.
The model utility content:
Technical problem to be solved in the utility model be to overcome existing technological deficiency provide a kind of rational in infrastructure, with low cost, the tensioning adjustment range is wide, tension effects is good, easy to operate, and can be fit to the tensioning of all kinds of metal-cutting machine tool belts, a kind of belt stretcher with good versatility.
Technical problem to be solved in the utility model adopts following technological scheme to realize:
A kind of belt stretcher, it is characterized in that: comprise the main shaft casing, described main shaft casing one side is provided with motor, be connected with belt pulley on the described motor, described main shaft casing upside is equipped with moving slide board, described moving slide board upside is provided with belt, described belt is connected on the belt pulley, described moving slide board is provided with tooth bar, described tooth bar is provided with nut, described main shaft casing one side is provided with the tooth axle, is connected with the tensioning handlebar on the described tooth axle, and described moving slide board is fixed on the main shaft casing by connecting screw;
Described tooth bar is fixed on the moving slide board by nut;
Described tooth bar and the engagement of tooth axle;
Described belt pulley passes moving slide board, and described moving slide board is connected on the motor by fixing bolt;
Have kidney slot on the described moving slide board, the length of kidney slot depends on the adjustment range of tensioning, unclamps the mounting screw on the moving slide board, and described moving slide board can move by the kidney slot along self on its mounting plane.
The beneficial effects of the utility model are: when belt needs tensioning, unclamp the mounting screw on the moving slide board, pull the tensioning handlebar, drive the rotation of tooth axle by the tensioning handlebar, tooth axle rotating band carry-over bar straight line moves, tooth bar and moving slide board are installed together, so moving slide board moves along the kidney slot of moving slide board, motor is installed on the moving slide board, and belt pulley is installed on the motor, and belt is installed on the belt pulley, the mobile movement that drives belt pulley by moving slide board, when arriving required tension position, the mounting screw on the locking moving slide board has been realized the tensioning to belt.This belt stretcher is simple in structure, with low cost, the tensioning adjustment range is wide, tension effects is good, easy to operate, and can be fit to the tensioning of all kinds of metal-cutting machine tool belts, have good versatility.
