Abstract
A grooving machine is composed of casing, motor, speed reducer, rotary shaft supported by bearing, blade on the rotary shaft, and two side-by-side bearings on the rotary shaft between speed reducer and blade. The speed reducing mechanism is a two-stage speed reducer. A hole check ring and a framework oil seal are arranged between the main supporting bearing and the blade, and a dust cover is arranged at the air inlet of the motor. The motor cavity is communicated with the slotted cavity through an air duct, and an air outlet of the air duct in the slotted cavity exceeds the axial lead of the blade rotating shaft.
Description
The utility model relates to the electric tools technical field, particularly a kind of groover.
At present, in interior decoration or building construction process, often on metope or ground, slot, so that bury electric wire or water pipe underground.Chinese patent just discloses a kind of " metope groover " for No. 92221675.4.But there is following shortcoming in it:
1, the bearing that is used for the supporting blade power transmission shaft is arranged at the both sides of blade, makes the loading and unloading inconvenience of blade.
2, the one-level speed change is adopted in power output, and the moment of torsion of its output is less, in use the blade stuck phenomenon can occur.
3, owing to dust in the groover course of work is bigger, dust is easy to enter in motor or the bearing, damages groover.
When 4, slotting, need a negative pressure device carry out dust suction, increased use cost.
The purpose of this utility model is: the groover that a kind of working stability is reliable, easy to use, the life-span is long is provided.
In order to reach the above purpose, the utility model is achieved through the following technical solutions:
A kind of groover, be provided with motor in the casing, be provided with fan blade in the motor cavity, casing is provided with handle, and the casing bottom is provided with base plate, the motor via reducer structure links to each other with rotating shaft, rotating shaft is supported in the casing by block bearing, and blade is housed in the rotating shaft, and blade is located in the fluting chamber, its part is protruded base plate plane, and the fluting chamber is provided with dust-exhausting port; Two main step bearings are located in the rotating shaft between reduction gearing and blade side by side.
In the utility model, described reducing gear is two stage reducer preferably.Preferably be provided with hole back-up ring, outside framework oil seal between described main step bearing and blade; The air intake place of motor is provided with dust cover on the casing.
In the utility model, described motor cavity preferably communicates with the fluting chamber by an air channel; The air outlet of air channel in the fluting chamber preferably surpasses the axial line of blade shaft.The air channel preferably is provided with a standby dust discharge perforate.
Advantage of the present utility model is: because two main step bearings are located in the rotating shaft between reduction gearing and blade side by side, make bearing can bear bigger pressure, and not fragile; It is easy to take the fluting chamber simultaneously apart, installs and changes blade conveniently.Because reducing gear is two stage reducer, can increase the output torque of rotating shaft, when slotted in metope or ground, the blade stuck phenomenon can not appear.Owing to be provided with hole back-up ring, outside framework oil seal between main step bearing and blade; The air intake place of motor is provided with dust cover, makes dust can not enter bearing and motor, prevents to damage groover, increases the service life.Because the motor cavity communicates with the fluting chamber by an air channel; Can utilize the dust discharge of motor radiating wind, need not negative pressure device.
Be elaborated the utility model in order more clearly to illustrate below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model air channel portion schematic diagram.
Fig. 3 is this material utility model main step bearing portion enlarged drawing.
In conjunction with Fig. 1, Fig. 2, shown in Figure 3: be provided with motor 2 in the casing 1 of groover, be provided with fan blade 3 in the motor cavity, casing is provided with handle 4, and the casing bottom is provided with base plate 5, and motor links to each other with rotating shaft 6 by two stage reducer, can increase the output torque of rotating shaft.Certainly also can adopt one or more levels reducer.Blade 10 is housed in the rotating shaft, and blade section is protruded base plate plane.Rotating shaft 6 is supported in the casing by block bearing 7,8,9.Two main step bearings 7 are located in the rotating shaft 6 between reduction gearing and blade side by side, make bearing not fragile; Be easy to install and change blade simultaneously.10 on main step bearing 7 and blade are provided with hole back-up ring 12, outside framework oil seal 13; The air intake place of motor is provided with dust cover 17 on the casing, makes dust can not enter bearing and motor, prevents to damage groover.
The motor cavity communicates with fluting chamber 19 by an air channel 14; The dust-exhausting port 11 in fluting chamber connects a flexible pipe 18, can utilize the dust discharge of motor radiating wind, need not the negative pressure device dust discharge.The air outlet 15 of air channel in the fluting chamber surpasses the axial line of blade shaft, is beneficial to the discharge dust.The air channel is provided with a standby dust discharge perforate 16, when metope is vertically slotted, opens standby hole, and larger particles can be discharged from standby hole.Certainly, in the utility model, dust suction also can be carried out by a negative pressure device in the fluting chamber, and unfavorable heat radiation wind with motor.
