Technical Field
The utility model relates to the technical field of machining, in particular to a flexible spring grinding wheel device for polishing pin shaft parts.
Background
The pin shaft parts are various in variety and widely applied to coal machine equipment, engineering equipment and agricultural machinery equipment. The machining of the pin shaft parts mainly comprises the step of turning blank bars, and when the machining allowance of the blank is large, great waste is caused, so that in order to save raw materials, the blank size of most pin shaft parts is properly reduced, and the machining allowance is reduced.
Before rough and finish machining, the oxide skin on the surface of the existing blank bar needs to be turned off by a cutter to ensure machining clamping accuracy.
However, when the machining allowance becomes smaller, the turning process of the oxide scale has the following technical defects: firstly, the wear on the tip can be very severe; secondly, if the surface oxide skin of the blank is too thick or the roundness of the blank is not enough, the problem that the surface oxide skin of the outer circle of the blank cannot be turned exists.

a spring which is pressed in the gear sleeve, wherein one end of the spring is abutted against the baffle plate, and the other end of the spring is abutted against the end face of the gear shaft section;
and the grinding wheel is fixed at one end of the optical axis section, which is far away from the gear shaft section, and is coaxial with the mounting shaft.
Optionally, the rotary driving member is a motor.
Optionally, the grinding wheel is a bowl-shaped grinding wheel.
When the rotary grinding machine is used, the shell of the rotary driving piece is fixed on the lathe, so that the output shaft of the rotary driving piece is vertical to the axis of the workpiece, the grinding wheel is abutted on the outer circular surface of the workpiece, and the output shaft of the rotary driving piece rotates to drive the mounting shaft to rotate through the engagement of the inner straight teeth and the outer straight teeth, so that the grinding wheel is driven to rotate to grind the workpiece in polarity; when the oxide skin is too thick or the roundness of the blank is insufficient, the mounting shaft can axially move relative to the gear sleeve, and the grinding wheel can be always abutted on the outer circular surface of the workpiece for grinding under the action of the spring.
Compared with the prior art, the technical scheme provided by the utility model has the following advantages:
according to the flexible spring grinding wheel device for grinding the pin shaft parts, the grinding wheel is used for replacing a cutter, the rotary driving piece outputs torque and transmits the torque to the grinding wheel through the gear sleeve and the mounting shaft, so that the grinding wheel rotates to grind a workpiece, and the aggravation of cutter point abrasion caused by small machining allowance can be avoided; and the spring is matched with the guiding of the optical axis section and the annular cover plate and the guiding of the inner straight teeth and the outer straight teeth, so that the grinding wheel can be flexibly contacted with the outer circular surface of the workpiece all the time no matter how the roundness and the coaxiality of the pin shaft type part change, and the grinding of the surface oxide skin of the outer circular surface of the blank is finished, thereby avoiding the phenomenon that the surface oxide skin of the outer circular surface of the blank cannot be turned due to the excessive thickness of the surface oxide skin of the blank or insufficient roundness of the blank in the prior art.
