Description

Grinding wheel dressing device

Technical Field

The utility model discloses a grinding wheel renovation field, concretely relates to a grinding wheel renovation device for bearing chuck formula double-ended grinding machine.

Background

The bearing double end faces are the reference surfaces of the bearing and also the positioning surfaces of the subsequent grinding process, so that the grinding wheel surface shape and the grinding wheel finishing mode for grinding the double end faces of the bearing have very high requirements when the double end faces of the bearing are ground.

The grinding wheel material commonly used by the bearing chuck type double-end-face grinding machine is brown corundum, and the grinding wheel finishing mode is as follows: one end of the dressing arm is provided with a diamond pen perpendicular to the dressing arm, and the other end of the dressing arm is arranged on the rotating shaft, so that the diamond pen can move on the surface of the grinding wheel to play a role in dressing the grinding wheel. The grinding wheel made of brown corundum has the defects of high grinding wheel abrasion, frequent grinding wheel replacement, low production efficiency, point-type dressing of diamond pens, low dressing speed and long grinding wheel dressing time, so that the grinding wheel dressing device capable of overcoming the defects is very important.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a grinding wheel truing device, including the dressing disk main part, the dressing disk main part week side is fixed with at least one oilstone piece, the oilstone piece is from the at least one side protrusion of dressing disk main part. The thickness of the oilstone block is larger than that of the dressing disc main body, and the oilstone block protrudes from two sides of the dressing disc main body, so that two grinding wheels can be conveniently dressed simultaneously. The dressing disk main body is also fixedly provided with a rotating shaft, and the rotating shaft can rotate under the driving of a motor, so that the CBN grinding wheel is dressed.

The bayonet socket has been seted up to trimming disk main part week side, the oilstone piece is fixed in the bayonet socket, still includes the wedge, and the wedge passes through the fix with screw in the bayonet socket and restricts the oilstone piece and removes. The shape and size of the wedge-shaped block are matched with the oilstone block and then matched with the bayonet. The dressing disc main body is provided with a through hole for screw thread connection of a screw, the dressing disc main body between the through hole and the bayonet is provided with a through hole screwed with the screw, and the wedge-shaped block is provided with a threaded hole screwed with the screw.

The oilstone blocks are arranged eight and evenly fixed on the periphery of the main body of the dressing disk, and the eight oilstone blocks for dressing the CBN grinding wheel can enable the abrasive particles of the grinding wheel to fall off easily.

Compared with the prior art, the utility model has the advantages of: the utility model discloses simple structure has not only solved bearing chuck formula double-ended grinding machine emery wheel wearing and tearing fast, change frequent problem, when still having solved the repairment emery wheel, point type buddha's warrior attendant pen repairment speed is slow, and the long problem of takies time is maintained to the emery wheel.

Detailed Description

In order to better understand the invention for those skilled in the art and to define the claimed scope more clearly, the invention will be described in detail below with respect to certain specific embodiments of the invention. It should be noted that the following description is only a few examples of the present invention, and the specific and direct descriptions of the related structures are only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of the present invention.

Referring to the drawings, the following technical scheme is adopted in the utility model, a grinding wheel truing device comprises a truing disc main body, at least one oilstone block is fixed on the periphery of the truing disc main body, and the oilstone block protrudes from at least one side of the truing disc main body. The thickness of the oilstone block is larger than that of the dressing disc main body, and the oilstone block protrudes from two sides of the dressing disc main body, so that two grinding wheels can be conveniently dressed simultaneously. The dressing disk main body is also fixedly provided with a rotating shaft, and the rotating shaft can rotate under the driving of a motor, so that the CBN grinding wheel is dressed.

As shown in fig. 3, left side emery wheel and right emery wheel are two parallel emery wheels on the same axial lead to can rotate around same axial lead, and two emery wheels can follow the axial lead direction and control the removal, under the drive of motor, the utility model discloses can use the rotation axis to rotate as the axis, the axial lead of rotation axis is parallel with the axial lead of emery wheel, the utility model discloses can be at existing equipment, for example lead screw conveying mobile device along the arrow head direction motion in fig. 3, between two parallel emery wheels of business turn over, realize the renovation of emery wheel.

At the during operation, as shown in fig. 4, two parallel emery wheels are rotatory, the utility model discloses rotatory along the rotation axis, under screw drive's drive, let the utility model discloses slowly get into between two parallel emery wheels are rotatory, then make left and right emery wheel slowly be close to the utility model discloses, the surface and the emery wheel surface contact of oilstone piece, the emery wheel surface will be maintained unnecessary part by oilstone piece surface, play the emery wheel and maintain the effect.
