The utility model has the advantages of steady run, no noise, no pollution and high work efficiency.

Description

Grinder

The utility model relates to a kind of grinder.

The kind of special grinder is a lot, a kind of lapping device of hard stone button is disclosed as Chinese patent CN2209014, this device mainly includes jig, the power source of grinding tool and their each autorotations of drive, jig comprises a chuck and fit portion, have the spiral shell button in the fit portion, match, be surrounded with groove on the working face of grinding tool with the spiral shell button of chuck bottom.Chinese patent CN2216886Y discloses the contour equal pressure grinder of a kind of stone grinder for another example, and this machine is made up of rocking arm, head, electronic, mill, it is characterized in that at slide cartridge of rack sleeve arranged outside, the slide cartridge lower end is provided with to press compiles spring; The slide cartridge wall is provided with tooth bar, with the stem gear engagement of worm and gear pressurized clutch middle-end; On head, be provided with the show rulers of spring compression travel.Its advantage is that pressure is delivered on the grinding block with contour equipressure by spring, has realized the dynamic pressure of stone slab is ground; Have adjustable in pressure, scale shows pressure, can fast lifting etc. function; Simplify operation, improved work efficiency.

The purpose of this utility model is: a kind of grinder that grinds aluminium spacer ring end face that is applicable to is provided.

The technical solution that realizes above-mentioned purpose is like this, and grinder is made up of frame, motor, reductor, line shaft and abrasive disk, it is characterized in that:

Abrasive disk is located at the axle head of line shaft, and the top of abrasive disk circumference is provided with one and is connected annular fixed mount with frame, and uniform plural V-type frame is respectively equipped with bearing on the two ends of V-type frame on the annular fixed mount; Be provided with building ring between the two bearings.

The utlity model has the remarkable advantage of two aspects:

One, this machine structural design compactness, reasonable, use, easy to operate;

Two, the running of this machine steadily, noiselessness, pollution-free, high efficiency not only can be used for the aluminium spacer ring and grinds, and also can be used for the grinding of the spool of valve etc.

Description of drawings.

Fig. 1 is the utility model structural representation.

Fig. 2 overlooks enlarged drawing for the utility model.

Below in conjunction with accompanying drawing, the utility model is described further by embodiment.

As seen from Figure 1, this grinder is made up of frame 3, motor 1, reductor 2, line shaft 5 and abrasive disk 9, and its line shaft 5 is loaded on the frame 3 by bearing, at the middle part of line shaft 5 thrust bearing is housed also, has overcome the defective of axial sinking.Abrasive disk 9 is loaded on the axle head of line shaft 5 by axle sleeve 8, and abrasive disk 9 is by being bolted on the axle sleeve 8, and axle sleeve 8 is fixed on the line shaft 5 by key 7 and screw 6.Annular fixed mount 12 is fixed on frame 3 tops, and is positioned at the circumference top of abrasive disk 9, and uniform four V-type fixed mounts 11 are equipped with bearing respectively on the annular fixed mount 12 on the two ends of V-type fixed mount 11; The axle of bearing is parallel with line shaft.Building ring 13 is housed respectively between the two bearings.

During use, workpiece is put into building ring 13, behind the starting motor 1, the moving building ring 13 of the rotating band of abrasive disk 9 rotates round about, its principle is, building ring 13 is subjected to V-type fixed mount 11 upper bearing (metal)s restrictions and can follow abrasive disk 9 to change, and forces building ring 13 to rotate to abrasive disk 9 opposite directions, is placed on workpiece in the building ring 13 also simultaneously along with rotating together.In building ring 13, also must put abrasive sand and some other materials.This machine can be used for the grinding that diameter is 250 millimeters workpiece of 1 millimeter～φ of φ, and grinding precision is within 1～5 of the scholar.

Claims

1, grinder is made up of frame, motor, reductor, line shaft and abrasive disk, it is characterized in that:
