Description
The utility model relates to a kind of bench grinder.
Bench grinder is used for the plane of workpiece or the conical surface are ground.Existing bench grinder complex structure, inefficiency, operation is also inconvenient, so be badly in need of a kind of new and effective grinder of invention.
Existing bench grinder mainly contains following shortcoming:
1, existing some bench grinder places the workbench top to motor, makes the grinder complicated integral structure, and parts are many, easy break-down, and be not easy to operation; Bulky, the vibration of motor causes that easily mill beats, thereby has reduced Grinding Quality; Motor places the workbench top, and this version has limited motor power, makes this grinder can only use low-power motor, thereby has limited the scope of application of grinder.
2, existing some bench grinder has adopted motor is placed the workbench below, and has directly driven the grinding workpiece rotation, and the version that mill does not change.But so,, will increase load,, cause vibration, influence Grinding Quality if the workpiece out-of-shape will produce centrifugal force to motor if workpiece is very heavy.
This shows that existing bench grinder has many shortcomings, be badly in need of a kind of novel bench grinder of invention.
And the utility model that this paper proposes is the creative new departure that designs at the shortcoming that has bench grinder now.
The purpose of this utility model is that a kind of novel bench grinder, i.e. " bench grinder " will be provided.It has distinguished advantage, and is existing as follows with regard to benefit analysis of the present utility model:
1, the grinder that the utility model proposes places the workbench below to motor, and by a series of gear drive, drive the mill rotation, and grinding workpiece is motionless.Like this, both alleviated the load of motor, and made complete machine structure simple again simultaneously, parts reduce, and are convenient to operation.
2, the grinder that the utility model proposes adopts a series of gear drive, the efficient height of transmission not only, and vibrate for a short time, complete machine is more stable.
The purpose of this utility model is achieved in that motor is fixed on the workbench below, and drive a series of reduction gearing by motor, the power of motor is passed to the workbench top by the workbench below, and drive the mill rotation, and grinding workpiece clamps motionless by chuck.
Like this, just produced relative motion between mill and grinding workpiece, grinding work has just begun.Chuck is fixed on the piston, and the piston other end and prismatic support connect, and the other end of prismatic support 27 is fixed on the workbench below.Like this, movable prismatic support just can make piston and chuck rise or decline, makes grinding work very convenient.The grinder that the utility model proposes all adopts gear drive, and not only the transmission efficiency height is rational in infrastructure, and amplitude is little, the Grinding Quality height.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the bench grinder structure chart that the utility model proposes.
Fig. 2 is the left view according to the local parts of Fig. 1 proposition.
Describe details and working condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete device that the utility model proposes.
