Description
Technical field
The utility model belongs to technical field of operation, is related to a kind of grinding attachment, particularly a kind of amary tape grinding machine with
Driving wheel positioner.
Background technology
Amary tape grinding machine be by abrasive band with workpiece under a certain pressure and relative motion carries out finishing and adds to finished surface
The equipment of work.
The species of amary tape grinding machine is more, the belt sander (Authorization Notice No. that such as Chinese patent literature is recorded
CN2581116Y), belt sander (application publication number CN102909632A) etc..And amary tape grinding machine as shown in Figure 1, belt-sanding
Machine includes support 1, and main shaft 2 is rotatably connected on support 1, and the motor being connected with main shaft 2 is provided with support 1, main shaft 2
Two ends are mounted on polishing wheel 3, and the rear side of polishing wheel 3 is provided with tensioning wheel 4, and the lower section of polishing wheel 3 is provided with supporting roller 5；Tensioning wheel 4
The adjustment arm 6 for being capable of telescopic adjustment by length between support 1 is connected；Supporting roller 5 is fixed on support 1 by fixed seat 7
Side on.Polishing wheel 3, tensioning wheel 4 and supporting roller 5 are located at the inner side of abrasive band 15, and its length elongation reality is made by manipulating adjustment arm 6
Now it is tensioned abrasive band 15；Make its contraction in length by manipulating adjustment arm 6, abrasive band 15 is in relaxed state, and then is conveniently replaceable abrasive band
15.According to actual conditions, abrasive band 15 only can be tensioned by polishing wheel 3 and supporting roller 5, then supporting roller 5 need to adjust dress using belt wheel
Put application publication number CN101767304A to be fixed on bottom surface, the position of supporting roller 5 is made by the handwheel for rotating belt pulley regulating device
Decline is put, and then realizes tensioning abrasive band 15；The position of supporting roller 5 is set to increase by reversely rotating handwheel, and then abrasive band 15 is in
Relaxed state, and then it is conveniently replaceable abrasive band 15.
As client is to Product processing efficiency requirements more and more higher, so want to shorten amary tape grinding machine in abrasive band more
The time required to changing.
The content of the invention
The utility model proposes a kind of supporting roller positioner of amary tape grinding machine, technology to be solved in the utility model
Problem is how to shorten replacing required time in abrasive band in amary tape grinding machine.
The technical problem to be solved of the present utility model can be realized by following technical proposal：This amary tape grinding machine with
Driving wheel positioner, including fixed seat and swing arm, the rotating shaft between swing arm and fixed seat by that can swing up and down swing arm are connected
Connect；The one end of swing arm offers the axis hole worn for the wheel shaft of supporting roller；By making between the one end and fixed seat of swing arm
All the time the elastic component with downward wobble drive is connected the one end of swing arm.
This supporting roller positioner is applied when on amary tape grinding machine, fixed seat be fixed on the support of amary tape grinding machine or
Fix on the ground.When amary tape grinding machine needs to use polishing wheel, tensioning wheel and supporting roller tensioning abrasive band, adjusted by manipulating
Arm makes its length elongation realize tensioning abrasive band and draw springs；When need to change abrasive band, operation swing arm make one end continue to
It is upper to swing certain stroke so that abrasive band is in relaxed state, and then be easy to take out old sand band and be inserted in fresh sand band, Zhi Houzai
Release swing arm, tensioning wheel is tensioned fresh sand band in the presence of elastic component.When amary tape grinding machine only needs to use polishing wheel and supporting roller
During tensioning, operation swing arm makes one end be swung up certain stroke so that abrasive band can be inserted in, and discharge swing arm again afterwards,
Bearing up pulley is tensioned abrasive band in the presence of elastic component；When need to change abrasive band, it is certain that operation swing arm makes one end continue up swing
Stroke, takes out old sand band and is inserted in fresh sand band, discharges swing arm again afterwards, and tensioning wheel is tensioned fresh sand in the presence of elastic component
Band.
In the supporting roller positioner of above-mentioned amary tape grinding machine, for face contacts between the swing arm and fixed seat, this
Sample can ensure the stability that swing arm swings, you can be effectively prevented from swing arm horizontal hunting, and then improve the stability of supporting roller.
In the supporting roller positioner of above-mentioned amary tape grinding machine, it is fixed with the swing arm and is arranged concentrically with axis hole
Axle sleeve.Axle sleeve is remarkably improved connective stability between supporting roller and swing arm.
In the supporting roller positioner of above-mentioned amary tape grinding machine, the other end of the swing arm is fixed with handlebar stem or pin
Treadle.Handlebar stem or foot-driven lever are set and cause that swing arm forms lever, with manipulating more laborsaving and more easily advantage；Make simultaneously
Workman manipulate swing arm position principle abrasive band, in other words can will manipulate swing arm location arrangements on more suitably position.
Compared with prior art, this supporting roller positioner can eliminate error in length and the adjustment arm lengths adjustment in abrasive band
It is difficult manipulation, the i.e. not steerable defect of abrasive band rate of tension.Machined using the belt-sanding with this supporting roller positioner
During workpiece, workpiece is pressed on abrasive band, and elastic component can stretch naturally, and then elimination causes abrasive band because workpiece is pressed on abrasive band
Rate of tension is improved and the problem of easy fracture.It follows that the present invention realizes shortening abrasive band by changing the location structure of supporting roller
The time required to abrasive band is changed in grinder.
