Abstract
The utility model discloses a centerless grinder grinding wheel spindle drive mechanism, including the spindle drum, the spindle drum front end is provided with the motor, the motor passes through the motor fixing base to be fixed on the spindle drum, the spindle drum rear end is provided with the main shaft of taking the emery wheel, motor output shaft passes through the shaft coupling and is connected with grinding wheel spindle, the spindle drum bottom still is provided with adjusting device, motor output shaft's axle center with grinding wheel spindle's axle center is concentric, just so can guarantee the synchronous revolution of main shaft and motor, avoids the skew in main shaft axle center to reducing main shaft starting friction power, obtaining higher running accuracy and operation stability, the long -term and stable state of main shaft operates, is favorable to promoting the quality and the production efficiency of product.
Description
Technical field
This utility model is related to mechanical equipment technical field, more particularly, to a kind of coreless grinder sand wheel main shaft drive mechanism.
Background technology
Grinding machine is the lathe that using grinding tool, surface of the work is carried out with grinding, and centerless grinder to be one kind do not need adopts
The axle center of workpiece and implement a class grinding machine of grinding, mainly by emery wheel, guide wheel and supporting plate are constituted；On centreless grinding machine external,
Workpiece without top centering and supports, and is placed between emery wheel and guide wheel, and by supporting plate and guide wheel supporting, emery wheel high-speed rotation is entered
Row grinding, guide wheel, with slower speed rotating Vortex, drives workpiece rotation to make feed motion.Traditional centerless grinder belt pulley is direct
It is arranged on main shaft, rotated come transmission main shaft by belt.This drive mechanism, the tensile force of belt acts directly on main shaft
On, the tensile force of belt can lead to for main shaft to draw skew, thus easily occurring starting frictional force greatly, unilateral abrasion, rotation in bearing shell
Turn precision and stability is not high, the final accuracy of manufacture affecting product.
Utility model content
For deficiency of the prior art, this utility model provides a kind of coreless grinder sand wheel main shaft drive mechanism, energy
Ensure that main shaft is rotated with motor in synchrony so that main shaft starts easily, running accuracy is high, and run stability is good, the product system of acquisition
Manufacturing accuracy is high.
To achieve these goals, this utility model employs following technical scheme and is addressed: a kind of centerless grinder
Grinding wheel spindle drive mechanism, including spindle drum, described spindle drum front end is provided with motor, and it is solid that described motor passes through motor fixing seat
It is scheduled on spindle drum, described main shaft base rear end is provided with the main shaft with emery wheel, described motor output shaft passes through shaft coupling and emery wheel
Main shaft connects, and described spindle drum bottom is additionally provided with adjusting means.
In the such scheme it is preferred that axle center of described motor output shaft is concentric with the axle center of described grinding wheel spindle, by adjusting
The axle center that regulating device realizes motor output shaft is concentric with grinding wheel spindle axle center.
Compared with prior art, this utility model is had the advantages that and is coupled motor with main shaft by shaft coupling,
The axle center realizing motor output shaft by adjusting means is concentric with grinding wheel spindle axle center, so it is ensured that main shaft and motor same
Step rotation, it is to avoid the skew of spindle axis, thus reducing main shaft to start frictional force, obtaining higher running accuracy and operating is stable
Property, the long-term and stable state operating of main shaft, be conducive to quality and the production efficiency of improving product.
Brief description
Fig. 1 this utility model structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, this utility model is further described.
Referring to Fig. 1, a kind of coreless grinder sand wheel main shaft drive mechanism, including spindle drum 2, the setting of described spindle drum 2 rear end
There is motor 6, described motor 6 is fixed on described spindle drum 2 by motor fixing seat 5, described spindle drum 2 front end is provided with band sand
The main shaft 3 of wheel 1, described motor output shaft 8 is connected with described main shaft 3 by shaft coupling 4, and described spindle drum 2 bottom is additionally provided with
Adjusting means 7, the axle center of described motor output shaft 8 is concentric with the axle center of described grinding wheel spindle 3, so it is ensured that main shaft with electricity
The synchronous rotary of machine, it is to avoid the skew in main shaft 3 axle center, thus reducing main shaft 3 to start frictional force, obtain higher running accuracy and
Run stability, the long-term and stable state operating of main shaft 3, be conducive to quality and the production efficiency of improving product.
Protection domain of the present utility model includes but is not limited to embodiment of above, and protection domain of the present utility model is to weigh
Sharp claim is defined, and any replacement that those skilled in the art that this technology is made is readily apparent that, deformation, improvement each fall within
Protection domain of the present utility model.
