The grinding machine mainly adopts the principles of impact, rolling and grinding to crush materials, for example, the vertical roller mill adopts an assembly structure of revolution of a grinding wheel frame and rotation of a grinding wheel, so that the extrusion strength and the shearing capacity of the grinding wheel to the materials are enhanced, the effect of enhancing the grinding is achieved, and the grinding machine has the characteristics of high yield and high fineness of ground material powder. When the wheel frame revolves along the rotating shaft, the grinding wheel rotates along the grinding pin under the action of centrifugal force and is thrown to the grinding ring to press the inner wall of the grinding ring, so that grinding force is formed.
The grinding wheel frame is an installation carrier of a grinding wheel, in the prior art, the grinding wheel frame is fixedly installed on a rotating shaft, the upper end of the grinding wheel frame is tightly pressed and fixed through a round nut and a stop washer through threaded connection, and the grinding wheel frame is driven by the rotating shaft to revolve. Because the vibration is large during grinding, the round nut is easy to loosen and even separate after being used for a long time, so that the grinding wheel frame rotates under loosening, and the grinding machine is easy to damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a locking device of mill whetstone frame guarantees the locking dynamics, prevents that the whetstone frame is not hard up to cause the damage.
The utility model provides a technical problem can adopt following technical scheme to realize:
the utility model provides a locking device of mill wheel carrier which characterized in that: the novel rotary shaft comprises a lower sleeve and an upper sleeve, wherein the lower sleeve is in a boss shape and is provided with a boss and a base, an inner ring is an internal thread and is in threaded connection with a rotary shaft, the base is provided with a plurality of screw holes, and the upper sleeve is sleeved outside the boss and is fixedly connected with the base through bolts; the side surface of the lower sleeve is provided with a notch, and the outer circumferential surface of the boss and the inner hole of the upper sleeve are conical surfaces.
Preferably, the taper of the conical surface is 1: 10.
Preferably, the outer circumferential surface of the boss is in interference fit with the inner hole of the upper sleeve.
Preferably, the gap penetrates through the boss and the base, and the width of the gap is 2-4 mm.
Preferably, a cover cap is arranged outside the lower sleeve and the upper sleeve, a counter bore is formed in the top of the cover cap and is fixedly connected with the top end of the external rotating shaft through a screw, and the lower sleeve and the upper sleeve are covered inside after the cap edge below the cover cap is installed.
Preferably, the thickness of the base is larger than the locking length of the bolt, and the bolt cannot protrude out of the bottom surface of the base after the upper sleeve is completely sleeved into the boss.
The utility model discloses change the mode of the fixed mill wheel carrier of round nut locking for the tradition, cover integrated configuration about adopting, lower cover and axle threaded connection through set up tapering and opening under sheatheeing in, go up the cover cooperation and compress tightly the lower cover, the rotation axis is held tightly in the opening shrink, effectively guarantees the locking dynamics. And meanwhile, the dustproof cap is arranged, so that the continuous fastening of the locking device is further ensured.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic diagram of the present invention.
Fig. 3 is a schematic structural view of the lower case.
In the figure, 1 lower sleeve, 2 upper sleeve, 3 cap, 11 boss, 12 base, 13 internal thread, 14 screw hole, 15 gap and 16 conical surface.
Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Fig. 1-3 show the preferred scheme of the utility model, including lower cover 1 and upper cover 2, lower cover 1 and upper cover 2 are the steel material, and lower cover 1 is the boss shape, is equipped with boss 11 and base 12, and the inner circle is internal thread 13, with outside rotation axis (not shown in the figure) threaded connection. The base 12 is provided with a plurality of screw holes 14 (6 are provided in this embodiment), and the upper sleeve 2 is sleeved outside the boss 11 and is fixedly connected with the base 12 through bolts. The thickness of the base 12 is larger than the locking length of the bolt, so that after the upper sleeve 2 is completely sleeved (namely, contacted with the base 12), the bolt cannot protrude out of the bottom surface of the base 12 when being screwed down.
In order to ensure the locking force, a notch 15 is formed in the side face of the lower sleeve 1, the width of the notch 15 is 2-4mm, the notch penetrates through the boss 11 and the base 12, the outer circumferential surface of the boss 11 is a conical surface 16, the outer diameter of the end face of the boss is the smallest, the outer diameter of the part connected with the base 12 is the largest, the taper of the conical surface 16 is 1:10, and the inner hole of the upper sleeve 2 is also provided with the taper of 1:10 and is in interference fit with the conical surface 16.
