Technical field
The utility model relates to mechanical equipment technical fields, and in particular to a kind of machine-building design miniature polishing dress
It sets.
Background technique
Machine-building the treatment of surfaces of components or inner hole, which are usually required that, has dust, convex with certain finish or surface
Block etc., and grinding, cutting or skin of paint removal etc., will usually use sander to polish, existing sander is due to sand
Wheel diameter cannot be excessive, and therefore, the working efficiency for piece surface of polishing is low, and grinding wheel diameter is excessive to will lead to grinding wheel operating injustice
Surely, thus defective work piece surface, and polish surface and inner hole when need replacing special equipment, inconvenient to use, processing efficiency
It is low.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed
Reason, machine-building easy to use design miniature grinding device.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes driving gear, the first driven tooth
Wheel, the second driven gear, grinding wheel, fuselage, motor, radiator-grid, operation handle, dust absorption fan, sweep-up pipe, collecting box, cutter lock
Tight screw;The two sides of the driving gear are engaged with the first driven gear and the second driven gear, the first driven gear respectively
Pass through cutter lock screw respectively with the shaft end of the second driven gear and is fixed with grinding wheel;Motor is provided in the fuselage, electricity
Machine is drivingly connected by belt wheel and driving gear, and radiator-grid is provided on the shell of the fuselage on the outside of motor, and the end of fuselage connects
It is connected to operation handle;The air inlet of the dust absorption fan has two sweep-up pipes by flanged joint, and air outlet and collecting box connect
It connects, the bottom of sweep-up pipe is evenly equipped with several suction nozzles.
Preferably, the driving gear, the first driven gear and the second driven gear are mounted in cabinet, fuselage with
Cabinet is fixedly connected.
Preferably, the motor is located at the right part of fuselage.
Preferably, two sweep-up pipes are separately fixed at the two sides of cabinet.
The working principle of the utility model are as follows: the rotation of motor driven driving gear, driving gear drive the first driven gear
It is rotated together with the second driven gear, so that the grinding wheel of two driven gear shaft ends rotates together, while workpiece surface of polishing, sand
The size of wheel is without being made the larger polishing for being able to achieve large area, the stationarity since the size of grinding wheel is smaller, when operating
Preferably;Dust when polishing in the translateral sweep-up pipe sucking collecting box of dust absorption fan by keeping in;When polishing inner hole, two are dismantled
One of grinding wheel is changed to bistrique by the cutter lock screw on grinding wheel, also uses cutter lock screw by bistrique and driven tooth
Wheel shaft locking, can polish inner hole;Motor is located at right part, far from grinding wheel, reduces influence of the dust to motor, extends making for motor
Use the service life.
After adopting the above structure, the utility model is the beneficial effects are as follows: a kind of mechanical system described in the utility model
Make design miniature grinding device, can large area polishing, grinding efficiency height, run smoothly, will not defective work piece surface, more tool changing
Inner hole can be processed after tool, easy to operate, the utility model has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model;
Fig. 2 is the top view of Fig. 1.
Description of symbols:
Driving gear 1, the first driven gear 2, the second driven gear 3, grinding wheel 4, fuselage 5, motor 6, radiator-grid 7, operation
Handle 8, dust absorption fan 9, sweep-up pipe 10, collecting box 11, cutter lock screw 12, cabinet 13.
Specific embodiment
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Referring to such as Fig. 1 --- shown in Fig. 2, present embodiment adopt the following technical scheme that it include driving gear 1,
First driven gear 2, grinding wheel 4, fuselage 5, motor 6, radiator-grid 7, operation handle 8, dust absorption fan 9, is inhaled second driven gear 3
Dirt pipe 10, collecting box 11, cutter lock screw 12;The two sides of the driving gear 1 are engaged with 2 He of the first driven gear respectively
The shaft end of second driven gear 3, the first driven gear 2 and the second driven gear 3 passes through cutter lock screw 12 respectively and is fixed with
Grinding wheel 4;Motor 6 is provided in the fuselage 5, motor 6 is drivingly connected by belt wheel and driving gear 1, and the driving of motor 6 is actively
Gear 1 rotates, and driving gear 1 drives the first driven gear 2 and the second driven gear 3 to rotate together, thus two driven gears
The grinding wheel 4 of shaft end rotates together, while workpiece surface of polishing, and the size of grinding wheel 4 is able to achieve large area without being made larger
Polishing, since the size of grinding wheel 4 is smaller, stationarity when operating is preferable.
Driving gear 1, the first driven gear 2 and second driven gear 3 is mounted in cabinet 13, fuselage 5 and case
Body 13 is fixedly connected, and cabinet 13 and fuselage 5 are strip, is not taken up space.
The air inlet of the dust absorption fan 9 has two sweep-up pipes 10 by flanged joint, and air outlet and collecting box 11 connect
It connects, the bottom of sweep-up pipe 10 is evenly equipped with several suction nozzles, and two sweep-up pipes 10 are separately fixed at the two sides of cabinet 13, ash when polishing
Dirt is inner temporary by the translateral sweep-up pipe 10 of dust absorption fan 9 sucking collecting box 11, there is dust clean-up port on collecting box 11, convenient clear
Reason.
It is provided with radiator-grid 7 on the shell of the fuselage 5 in 6 outside of motor, prevents motor overheating.
The end of the fuselage 5 is connected with operation handle 8.
The motor 6 is located at the right part of fuselage 5, far from grinding wheel, reduces influence of the dust to motor, extends making for motor
Use the service life.
After adopting the above structure, present embodiment is the beneficial effects are as follows: one described in present embodiment
Kind of machine-building designs miniature grinding device, can large area polishing, grinding efficiency height runs smoothly, will not defective work piece table
