Description

A kind of wall sander

Technical field:

The utility model relates to a kind of wall sander of before plastering wall wall being polished in advance, being cleaned.

Background technology:

Wall sander of the prior art comprises the hand-held person in charge, disk and sanding apparatus, and the hand-held front end of being responsible for is fixed with a bridge piece, disk is installed in the free end of bridge piece, sanding apparatus is installed in the disk, and the hand-held rear end of being responsible for is equipped with motor, is in transmission connection by a flexible axle between motor and the sanding apparatus, during use, hold hand-held person in charge, starter motor, motor drives sanding apparatus by flexible axle and rotates, and then by sanding apparatus body of wall is polished, very convenient; But, in this structure, because motor is installed in the hand-held rear end of being responsible for, sanding apparatus is installed on the bridge piece of hand-held person in charge's front end, must come transmission by flexible axle between motor and the sanding apparatus, and the anti-twist intensity of flexible axle is very low, sanding apparatus is when the metope that polishing relatively slightly is pickled with grains or in wine, can produce bigger moment of torsion, thereby make flexible axle be easy to be twisted off, shorten the service life of this product, in addition, distance between motor and the sanding apparatus is long, and the flexible axle that needs also is long, and this has just increased the manufacturing cost of product.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of long service life, wall sander cheap for manufacturing cost are provided.

A kind of wall sander that provides according to the utility model, comprise the hand-held person in charge, disk and sanding apparatus, the hand-held front end of being responsible for is fixed with a bridge piece, described disk is installed in the free end of described bridge piece by a tumbler, described sanding apparatus is installed in the disk, the described disk back side is provided with a motor, and this motor is in transmission connection by a deceleration device and power transmission shaft and sanding apparatus.

The utility model also has following attached technical characterictic:

Described motor and described deceleration device all are installed in the disk back side by bolting, deceleration device comprises casing, is located in the casing and the pinion and the gear wheel of the transmission that is meshing with each other, wherein, pinion and motor output shaft are affixed, gear wheel is fixed on power transmission shaft one end, and this power transmission shaft other end and sanding apparatus are affixed.

Described power transmission shaft is installed on the disk by bearing.

Described hand-held person in charge's rear end part is equipped with motor power gauge tap and motor speed controller.

Also be connected with hose between described hand-held person in charge's front end and the disk.

A kind of wall sander according to the utility model provides has following advantage with respect to prior art:

First, in this structure, motor is installed in the disk back side, is in transmission connection by a deceleration device and power transmission shaft between itself and the sanding apparatus, and power transmission shaft is the hard axle of steel, its anti-twist intensity height, can bear very large torque, the sanding apparatus polishing torque that wall produced can not twist off it, thereby, product is not easy to damage long service life;

Second, in this structure, be in transmission connection by a deceleration device and power transmission shaft between motor and the sanding apparatus, wherein, deceleration device is simple common spur gear slowing-down structure, and power transmission shaft is very short ordinary steel axle, all can buy on market with very cheap price, thereby it is cheap for manufacturing cost.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure for amplifying schematic diagram of I among Fig. 1.

The specific embodiment:

With reference to Fig. 1, Fig. 2, according to a kind of wall sander described in the utility model, comprise the hand-held person in charge 1, disk 2 and sanding apparatus 3, hand-held 1 front end of being responsible for is fixed with a bridge piece 11, disk 2 is installed in the free end of bridge piece 11 by a tumbler 4, sanding apparatus 3 is installed in the disk 2, tumbler 4 can make disk 2 interior sanding apparatus 3 can rotate the angle of certain amplitude to different directions when work, to improve polishing quality to metope, disk 2 back sides are provided with a motor 5, this motor 5 is in transmission connection with sanding apparatus 3 by a deceleration device 6 and power transmission shaft 7, power transmission shaft 7 can adopt the hard axle of steel, its anti-twist intensity height can bear very large torque.

Motor 5 all is installed in disk 2 back sides by bolting with deceleration device 6, deceleration device 6 comprises casing 61, be located in the casing 61 and the pinion 62 and the gear wheel 63 of the transmission that is meshing with each other, greatly,

pinion

63,62 all select low-cost spur gear for use, to reduce the manufacturing cost of product, pinion 62 is affixed with motor 5 output shafts, gear wheel 63 is fixed on power transmission shaft 7 one ends, these power transmission shaft 7 other ends and sanding apparatus 3 are affixed, power transmission shaft 7 is installed on the disk 2 by bearing 8, and hand-held 1 rear end part of being responsible for is equipped with motor power gauge tap 9 and motor speed controller 10.

In sum, this sander is when work, earlier by motor power gauge tap 9 starter motors 5, pinion 62 on motor 5 output shafts rotates thereupon synchronously, do the rotation of slowing down with the gear wheel 63 of pinion 62 engagements thereupon, and the rotating speed after slowing down is passed to sanding apparatus 3 by power transmission shaft 7, at this moment, sanding apparatus 3 just can carry out polishing work to wall.

Hand-held person in charge between 1 front end and the disk 2 also is connected with hose 101, and this hose 101 is used for auxiliary dust catcher the wall ash that bruting process produces is siphoned away.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
