Description

The driven wheel regulating device of belt sander

Technical field

The utility model belongs to grinding technique field, is related to a kind of belt sander, especially a kind of belt sander Driven wheel regulating device.

Background technique

Belt sander is that indispensable equipment is ground in the industries such as hardware, hot-water heating.Belt sander includes rack, driving wheel And driven wheel, motor is installed in rack, driving wheel is mounted on the main shaft of motor or is also equipped in rack shaft, motor Main shaft be connected with shaft by belt, driving wheel is mounted on shaft.

There are mainly two types of for the mounting means of driven wheel, the first is tensioned such as the adjusting for the polishing machine that Chinese patent is recorded Mechanism（Authorization Notice No. CN2652595Y）, there is following shortcomings for the structure：1, the length of adjustment arm is longer and adjusts Whole arm needs to stretch, thus causes the free end amplitude of fluctuation for adjusting arm larger；2, motor operation can generate vibration, and vibration can be straight Conduction is connect to driven wheel；3, it is also not identical to be mounted on the position in shaft for different driving wheels, since adjustment arm is relative to electricity The shell of machine can not axially adjustable position, thus the wheel shaft position being only capable of according to the actual situation by adjusting driven wheel, realization change Become spacing between driven wheel and adjustment arm, the excessive driven wheel stability of spacing is poorer between driven wheel and adjustment arm.In short The structure has driven wheel stability deficiency.

A kind of regulating device for belt wheel that second of such as Chinese patent is recorded（Application publication number CN101767304A）, the knot There is following shortcomings for structure：1, space between dust gathering arrester and rack is occupied, there is a possibility that influencing dust gathering arrester arrangement；2, Pedestal is not easy to adjust relative to position between rack, by moving axially the wheel shaft of driven wheel when need to adjust driven wheel left-right position It realizes, it follows that the excessive driven wheel stability of spacing is poorer between driven wheel and rack.

Summary of the invention

The utility model proposes a kind of driven wheel regulating device of belt sander, technologies to be solved in the utility model Problem is how to improve driven wheel stability in belt sander.

The technical problems to be solved of the utility model can be realized by the following technical scheme：Scheme one：A kind of abrasive band The driven wheel regulating device of polishing machine, belt sander include rack and the shaft for installing driving wheel；Driven wheel adjusts dress It sets including overhanging arm and adjustment arm, overhanging arm is horizontally disposed and is located at the lower section of shaft, and overhanging arm is fixedly connected with rack；Overhanging It is equipped with extension arm in arm, overhangs the lock solid structure for being equipped on arm and extension arm capable of being made to be fixedly connected with overhanging arm；Adjust arm phase Overhanging arm is vertically arranged, the one end for adjusting arm is fixedly connected with extension arm, and the wheel shaft of driven wheel is vertical relative to adjustment arm It is arranged and the wheel shaft of driven wheel is fixedly connected with the other end of adjustment arm.

Scheme two：A kind of driven wheel regulating device of belt sander, belt sander include rack and for installing master The shaft of driving wheel；Driven wheel regulating device includes overhanging arm and adjustment arm, and overhanging arm is horizontally disposed and is located at the lower section of shaft, is hanged Arm is chosen to be fixedly connected with rack；Adjustment arm is vertically arranged relative to overhanging arm, is overhang and is arranged with connector sleeve on arm, pacifies on connector sleeve Equipped with the lock solid structure that connector sleeve can be made to be fixedly connected with overhanging arm；One end of adjustment arm is fixedly connected with connector sleeve, driven wheel Wheel shaft relative to adjustment arm be vertically arranged and the wheel shaft of driven wheel with adjust arm the other end be fixedly connected.

By selecting the overhanging arm for being suitble to diameter and suitable thickness to guarantee the rigidity of overhanging arm；It according to the actual situation can be Floor is set between overhanging arm and rack, further increases the rigidity of overhanging arm.Overhanging arm is fixed on the rack and adjusts arm Be fixed on overhanging arm on, can reduce motor oscillating to adjustment arm influence and and fully utilize rack two sides sky Between, avoid these components from influencing dust gathering arrester setting.Overhanging arm is mounted below shaft, thus can contracting short arm adjustment length, into And adjustment arm rigidity is improved, reduce the vibration of adjustment arm free end.It is opposite that driven wheel wheel shaft can not be adjusted when adjusting driven wheel position The spacing between adjustment arm, only adjustment adjustment arm is with small vibration since overhanging arm has rigidity foot relative to spacing between overhanging arm The advantages of, and then the stability of driven wheel can be significantly improved.In short, the driven wheel regulating device of this belt sander and existing There is technology to compare with the advantage that driven wheel stability is higher and belt sander is more general.
