Description

A kind of grinding attachment that is used on the abrasive machine

Technical field

The utility model relates to abrasive machine, is specifically related to the grinding attachment on the abrasive machine, more particularly, relates to the improvement of grinding attachment structure.

Background technology

In the prior art, all be provided with one in the abrasive machine by motor-driven grinding attachment, also claim grinding machine head, Fig. 1, Fig. 2 shows existing a kind of grinding machine head structure, in grinding machine head, be provided with main shaft 1, be connected the emery wheel of spindle nose, main shaft holder 2, drive motors 4 is connected with main shaft 1 by shaft coupling 6, on the end face of holder 2, be connected with the slideway gap plate 3 that is clamped on the guide rail by screw 7, there is following shortcoming in this grinding machine head structure: during adjustment screw 7 on adjusting the slideway gap plate, the axle center of motor 4 axle center and main shaft 1 can produce angular deviation and position deviation, because the axiality of motor axis and spindle axis has error, make the axiality between main shaft and the motor be not easy to be consistent, the vibration that is produced when main shaft rotates at a high speed can influence the grinding accuracy of emery wheel, promptly influences the surface smoothness and the surface roughness of workpiece.

The utility model content

The technical problems to be solved in the utility model is, a kind of grinding attachment that is used on the abrasive machine is provided, and this device is when adjusting the slideway gap plate, and motor axis and spindle axis can not produce angular deviation and position deviation yet, can guarantee requirement on machining accuracy.

The technical scheme that the utility model provides is as follows: construct a kind of grinding attachment that is used on the abrasive machine, the motor that comprises grinding machine head main shaft, main shaft holder, is connected with main shaft by shaft coupling, the slideway gap plate of clamping guide rail, also comprise a concentric ring that is enclosed within the through hole of main shaft holder and passes described slideway gap plate, the two ends of this concentric ring respectively with the concentric socket of flange flange of the through hole and the motor of described holder, the both ends of the surface of concentric ring respectively with a side end face of main shaft holder and the end face Joint of motor.

In above-mentioned grinding attachment, the appearance profile of the described concentric ring structure that is square, the link of itself and motor end face is the be square ring flange of structure of an appearance profile, on the end face of ring flange, be provided with the inner stopper that matches with described motor end face male half coupling, on its periphery, be provided with the screw corresponding with the connecting hole of described motor, the other end of described concentric ring is provided with the male half coupling that matches with described main shaft holder through hole, is provided with the corresponding connecting hole of a plurality of and described main shaft holder screw on the periphery of seam.

The utlity model has following advantage: make both rigidly connected concentric rings by between the end face of the end face of main shaft holder and motor, being provided with one, the axiality of main shaft and motor is easier agrees, when adjusting the slideway gap plate, because motor is fixed on the concentric ring, the influence that not changed by chute board gap angle, the axiality of main shaft and motor still is consistent, can not produce angular deviation and position deviation, the vibration that main shaft is produced when rotating at a high speed is little, can not influence the surface roughness of the grinding accuracy and the workpiece of emery wheel, make the shaft strength of main shaft even, prolong service life, main shaft separates easily with motor, is convenient to keep in repair and does not influence when repeating to assemble both axialities.
