Detailed description of the invention
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings:
Wall surface grinding machine, including operation handle, motor 7, and grinding head, grinding head is arranged on operation handle
Front end (this mounting means is prior art, and it discloses at ZL201320595632.8, operate handle
Front end be arranged on sleeve 11 by jointed shaft 10, sleeve 11 is sleeved on the transverse axis of top cover), described
Grinding head includes top cover, pedestal and mill assembly；It is provided with, on described top cover or pedestal, the mouth of pipe of bleeding, bleeds
The mouth of pipe is communicated to mill assembly by the gas circuit in top cover；The mouth of pipe of bleeding is connected to operate handle by trachea 1
Interior dust sucting pipeline, dust sucting pipeline and vacuum cleaner pipeline connection, this design makes grinding head when polishing metope
The dust produced can directly be drawn by vacuum cleaner, it is to avoid dust pollution, and, air pressure in mill assembly
Less than the air pressure outside mill assembly, this design makes the mill assembly can be with automatic absorbing on metope so that
Metope sanding operation operation is the easiest；
Described top cover 13 and pedestal (in the present embodiment, pedestal includes pedestal top 14 and pedestal bottom 19,
Pedestal top 14 and pedestal bottom 19 can also be designed to integral structure) between be provided with the torsion of motor 7
Square is transferred to the drive mechanism of mill assembly, and the output shaft of drive mechanism is eccentric shaft 24 or concentric shafts, described
The mill 28 of mill assembly is arranged on the lower end of eccentric shaft 24 or concentric shafts；In this design, output shaft is inclined
During mandrel, the motion of mill is vibrating type, and when output shaft is concentric shafts, the motion of mill is swinging.
In the present embodiment, motor is arranged on top cover, and the motor shaft of motor directly drives the umbrella tooth of drive mechanism
Wheel 40, it should be noted that, motor can also be arranged on the rear portion of operation handle (such as ZL201120513361.8
Disclosed in electrical installation), the motor shaft of motor by flexible axle transmission moment of torsion to drive mechanism, driver
Structure can have various ways, only needs to realize the purpose of moment transmission, in the present embodiment, drive mechanism
Use bevel gear 40, power output shaft 39, power input shaft 20, gear assembly and drive mechanism output shaft
Design, wherein, when top cover 13 and base-separation, power output shaft 39 and power input shaft 20 separate, dynamic
The downside of power output shaft 39 is provided with inner hexagonal hole, and power input shaft 20 upper end is outer-hexagonal axle；
Described top cover 13 and pedestal are connected by quick-changing mechanism, and described quick-changing mechanism is: be provided with in pedestal

Or rectangle or " D " shape, the profile of described protecting cover adapts with mill.
It should be noted that:
When the output shaft of drive mechanism is concentric shafts, the motion of mill is swinging, no matter mill why shape
Shape, the polishing track of mill can only be a circle, it is contemplated that the uniformity of mill polishing wall, mill is
Time circular, polishing is optimal；Mill is consistent with wall surface grinding machine series products on the market with the mounting means of protecting cover,
It is not described in detail in this.
When the output shaft of drive mechanism is eccentric shaft, eccentric shaft band movable grinding disc shakes back and forth, and the motion of mill is
(profile of protecting cover adapts vibrating type with mill, and protecting cover does not rotates, and mill can only shake back and forth, and can not
Freely rotatable), the polishing track of mill is close with its shape, and in the present embodiment, preferably mill is just shaped as
Triangle, this shape is almost suitable for the wall in all corners of polishing.
Preferably, the inner edge of described 17 weeks sides of protecting cover is provided with adhesive tape 15, and the inboard row of adhesive tape shows convex tendon
27；Described convex tendon is against on mill.The design of adhesive tape makes the gap of protecting cover and mill moderate, it is ensured that protect
Vacuum in lid so that grinding head can adsorb on metope, the design of convex tendon simultaneously makes the adhesive tape will not
It is fitted in completely on mill, between adhesive tape inwall and mill, there is air-suction channel all the time.Particularly point out,
When the output shaft of drive mechanism is eccentric shaft, mill shakes back and forth, and the inner side of adhesive tape is against on mill all the time.
As shown in Figure 4, mill is triangle mill, and its profile is triangle, corresponding, the profile of protecting cover is triangle
Shape, adhesive tape 15 is provided with three, sets up the inner side on three wing limits at protecting cover separately.
In the present embodiment, protecting cover does not turns, then mill can not turn, and this design is based on following 2 points: (1)
The inner side of adhesive tape is against on mill all the time, gives the resistance that mill rotates；(2) all sides of mill and protecting cover set
Being equipped with several soft posts 59, the upper end of soft post is fixed on protecting cover, and the lower end of soft post is fixed on mill, soft
The design of post makes mill not rotate, and can only shake.Soft post can be rubber column.
Preferably, when the output shaft of described drive mechanism is eccentric shaft, described protecting cover is arranged on pedestal bottom also
Can opposite base freely rotatable, the rotation centerline of described protecting cover is parallel also with the axis of the upper semiaxis of eccentric shaft
Close.In the present embodiment, the downside of pedestal bottom 19 is torus, and the middle part of protecting cover 16 is provided with and institute
State the through hole that torus is nested.
While protecting cover 16 rotates, band movable grinding disc rotates.Such as Figure 10, shown in 11, with profile as triangle
Mill as a example by, no matter on the corner line of metope vertically or tilt, during polishing, can pole
For convenience the wing limit of protecting cover is adjacent to wall corner line.In the present embodiment, select with protecting cover contact surface on the downside of pedestal
Property be provided with damping piece, it is for preventing rotation between pedestal and protecting cover excessively flexible, and this damping piece can
To be provided in rubber column or the ring pad at the through hole edge in the middle part of protecting cover.
Preferably, described pedestal it is provided with clamping or unclamps the gripping mechanism of protecting cover.In the present embodiment, institute
State downside in the middle part of protecting cover 16 and form ring gear 25 (in the lower edge of the center through hole that ring gear is molded directly within protecting cover
Side), described pedestal is provided with spacer pin 33, the side of spacer pin 33 lower end is provided with engages with ring gear 25
Moving tooth 32, described pedestal is additionally provided with the switching device controlling the engagement of moving tooth and ring gear or separating.This reality
Executing in example, this switching device is: the upper end of spacer pin is stretched out pedestal and is provided with the turning handle being easy to stir, limit
The middle part of position pin is set with orders about the spring moved on spacer pin.Press spacer pin and turn an angle, just may be used
Moving tooth 32 is made to depart from ring gear 25；Switching device can also is that the most common spring button formula design.It addition,
This gripping mechanism can also be: arranges knob on pedestal, the rotation of knob control a spacer pin push against or
Leave protecting cover.
Preferably, all sides of described pedestal are provided with more than one lead 35, and described top cover is provided with
The chute 26 chimeric with lead.In the present embodiment, it is respectively arranged with a guiding in the left and right sides of pedestal
Post 35, the left and right sides of top cover is correspondingly arranged on chute.When this design makes top cover and pedestal docking, more
Easily, dislocation will not be produced.
Preferably, described operation handle includes fore-stock and back handle, and the front end of fore-stock is connected with top cover,
Being provided with stretching structure between rear end and the back handle of fore-stock, described stretching structure is: the rear end of fore-stock
