Abstract

The utility model relates to an electric grinding tool used in the construction, which is characterized in that a cam actuating mechanism is used for driving a whetstone to do straight reciprocating motion. Therefore, no 'dead angle ' can be left even in a small area or a break corner part such as wall corners, stairways, windowsills, etc., at the time of grinding construction. The utility model has good moisture resistance and safety in use because an electric machine is provided with a waterproof buckler. The utility model needs no people to hold and is convenient to move at the time of flat surface construction. The reciprocating terrazzo grinding machine can be matched with an appropriative pulley yoke at the time of grinding the stand stone, which is easy to operate.

Description

Reciprocating terrazzo grinding machine

The utility model belongs to the building operations electric tools, is used for narrow and small area and knuckle place, as windowsill, the polishing located such as mark time (stair), step (corner), washroom, pond, balcony, flower bed.

At present, the machine tool that narrow and small area and the polishing of knuckle place are used is portable emery wheel, carries out work with rotation mode, and its shortcoming is: (1) is owing to the rotation construction, so work has " dead angle "; (2) water proofing property is poor, easily electric leakage, and safety can not guarantee that (3) power is little, inefficiency; (4) operating difficulties, abrasive wheel end face must be parallel with machined surface, grasps the arm fatiguability by the people.

In fact, portable emery wheel seldom uses at present, and the polishing at narrow and small area and knuckle place mainly by manpower, craft, exists dirty, tired, slow shortcoming.

The purpose of this utility model is exactly design in order to overcome above-mentioned shortcoming a kind of can be in narrow and small area and the polishing of knuckle place, high efficiency, and good waterproof performance, safe and reliable, labour-saving simple to operate electric grinding tool.

Feature of the present utility model is: in the grinding construction, oilstone is done straight reciprocating motion, and for this reason, the utility model has adopted special cam drive: respectively pacify a bearing 12 at driving lever 14 two ends that link to each other with motor shaft; Bearing 12 is respectively packed in the elliptical bearing groove 28 on the dial 16; The angle of two dial 16 installations is identical, i.e. the length diameter of axle installation direction unanimity of two elliptical bearing grooves 28; Dial 16, wheel carrier 17, wheel shaft 25, roller 27 are assembled into one, and roller 27 is contained in the straight-line groove 29 on the guide rail 26, and with straight-line groove 29 matched in clearance.Dial 16 is connected with oilstone 22 by wheel carrier 17, short column 18, long column 19.When motor rotated, oilstone did reciprocating linear motion.

Further specify structure of the present utility model and operating principle below in conjunction with accompanying drawing.

Fig. 1 is the complete section face of the facing assembling drawing of terrazzo machine;

Fig. 2 is that part sectioned view is looked on the left side of terrazzo machine;

Fig. 3 is the part drawing of the driving lever of terrazzo machine, and Fig. 4 is the part drawing of dial, and Fig. 5 is the part drawing of frame.

Handle 1 is by half dollar head rivet 2, be connected with bucker 6, switch 7, capacitor 8 is connected with bucker by screw respectively, india-rubber cable 4 passes bucker 6 by protective jacket 3, bucker 6 is connected with box 11 by screw, motor 5 is by bolt 10, nut 9 is connected with box 11, the square hole of driving lever 14 cooperates with the tetragonal prism of motor 5 rotating shafts, bearing 12 is connected as a single entity by pin 13 and driving lever 14, dial 16 is connected by countersunk head screw 15 with wheel carrier 17, bearing 12 is contained in the elliptical bearing groove 28 on the dial 16, short column 18, long column 19 is welded on respectively on the wheel carrier 17, and guide wheel 26 is connected by countersunk head screw 24 with box 11, and roller 27 is socketed in wheel shaft 25 two ends respectively, straight-line groove 29 matched in clearance on roller 27 and the guide rail 26, oilstone 22 respectively with short column 18, long column 19 is connected with column cap screw 22 by packing ring 21.

The operating principle of reciprocating type terrazzo machine: open switch 7, motor 5 rotates, driving driving lever 14 rotates, be contained in the bearing 12(band dust cap on the driving lever 14) move along the elliptical bearing groove 28 on the dial 16, thereby dial 16 is swung, dial 16 usefulness screws are fastened on the frame 17, oilstone 22 is by minor axis 18, major axis 19 usefulness screws are connected with frame 17, two of every wheel carrier 17() by two wheel shafts 25 four rollers 27 are housed, roller 27 rotates on wheel shaft 25, straight-line groove 29 moving linearlies on the guide rail 26, thereby make the grinding of oilstone 22 do straight reciprocating motion, oilstone 22 directions of motion are opposite, and complete machine does not have the phenomenon of swinging.

The utility model has the advantages that: 1. narrow and small of grinding and knuckle do not stay the dead angle, if any the cooperation of slide-bar frame, lifting, swing freely, but the grinding facade structures; 2. high efficiency is equivalent to four times of portable emery wheel; 3. owing to added the motor bucker, so not water funk pouring, leakproof is safe and reliable; 4. during the grinding plane, do not need artificial handle, without Manual pressurizing, operation easily; 5. grinding face is highly polished.

Claims

1, a kind of reciprocating type terrazzo machine is used for the grinding at building operations narrow and small area and knuckle place, mainly comprises motor 5, oilstone 22, it is characterized in that the cam mechanism that this terrazzo machine has adopted oilstone 22 to do reciprocating linear motion, the bucker 6 of protection motor 5.

2, cam mechanism as claimed in claim 1 is characterized in that forming like this: at the two ends of the driving lever 14 that links to each other with motor shaft a bearing 12 is housed respectively; Bearing 12 is packed in the elliptical bearing groove 28 on the dial 16; Elliptical bearing groove 28 length diameter of axle installation direction unanimities on two dials 16, and link to each other with frame 17; The wheel shaft 25 and the oilstone 22 of band roller 27 are housed on frame 17; Roller 27 is contained in the straight-line groove 29 on the guide rail 26.
