Description

Grinding piece pressing plate

Technical Field

The invention relates to the technical field of electric tool accessories, in particular to a grinding plate pressing plate.

Background

The grinder generally has a motor, a power output shaft of the motor is fixed with a flange or provided with a step, a left support sheet is fixed at the right part of the step, a pressure plate is fixed at the right part of the left support sheet through a screw rod and other components, and a grinding disc is clamped between the pressure plate and the left support sheet. The defects are as follows: after the pressing plate is used for a period of time, the grinding plate is easy to loosen, and when the pressing plate cannot move leftwards continuously, the grinding plate only needs to be discarded, so that certain waste is formed.

Disclosure of Invention

In view of the above-mentioned deficiencies of the prior art, it is an object of the present invention to provide a blade press plate having features that extend the useful life of the blade.

In order to achieve the purpose, the invention adopts the technical scheme that: grinding plate clamp plate, including the circular shape plate body, penetrating shaft hole about the middle part of plate body is equipped with, the left part diameter in this shaft hole is greater than its right part diameter, and the outer fringe that is close to this plate body on this plate body is equipped with 1 at least circular fixed orifices of group and 1 at least regular hexagon fixed orifices of group, circular fixed orifices and regular hexagon fixed orifices interval set up lie in same virtual circle, and simultaneously, still be equipped with a plurality of auxiliary holes on this plate body, the auxiliary hole is the blind hole left of opening, and the downthehole clearance fit of auxiliary holes is equipped with the kicking block, there is the screw through forked tail structural connection on the right-hand member face of kicking block, and, the bottom in auxiliary hole is equipped with the screw, the screw spiro union is in the screw, and the right-hand.

And a plurality of pointed cones protruding leftwards are distributed on the left end surface of the top block.

The center position of the left end face of the top block is smooth.

After adopting the structure, compared with the prior art, the invention has the advantages that: the effective service life of the abrasive disc can be prolonged. After the grinding plate pressing plate is used for a period of time, when the middle part of the grinding plate becomes thinner due to long-time stress and abrasion, the pointed cone can further tightly push the grinding plate only by screwing the screw, so that the grinding plate can be ensured to be continuously used, and the grinding plate has longer service life.

Detailed Description

Examples, see fig. 1-4: the refiner plate press comprises a circular plate body 10. Generally, the plate body 10 of the refiner plate press is adapted to cooperate with a left support plate on the power take-off shaft of a motor on a refiner. That is, the plate body 10 is fixed to the right side of the left support plate, and the grinding chip is sandwiched between the plate body 10 and the left support plate.

Specifically, the method comprises the following steps:

the middle part of the plate body 10 is provided with a left and right through shaft hole 11, and the diameter of the left part of the shaft hole 11 is larger than that of the right part thereof. That is, the shaft hole 11 is used to receive and pass through a power output shaft of the motor, and the left portion of the shaft hole 11 has a larger diameter in order to receive a fastening bolt or the like which may be provided on the left support plate. Of course, when the heat dissipation device is used specifically, fastening bolts and other parts may not be present according to different types of mills, and the left large-diameter portion can play a good heat dissipation role. At least 1 set of circular fixing holes 121 and at least 1 set of regular hexagonal fixing holes 122 are formed on the plate body 10 near the outer edge of the plate body 10. Obviously, the circular fixing holes 121 belonging to the same group are necessarily symmetrical about the center of the plate body 10, and the regular hexagonal fixing holes 122 belonging to the same group are necessarily symmetrical about the center of the plate body 10. The circular fixing holes 121 and the regular hexagonal fixing holes 122 are arranged at intervals and located on the same virtual circle o. Obviously, the virtual circle o must coincide with the center of the plate body 10. Meanwhile, the plate body 10 is provided with a plurality of auxiliary holes 13 on another virtual circle o'. Obviously, the virtual circle o and the virtual circle o 'both coincide with the center of the plate body 10, and the diameter of the virtual circle o is larger than that of the virtual circle o'. Auxiliary hole 13 is the blind hole of opening left, and clearance fit is equipped with kicking block 20 in auxiliary hole 13, has screw 21 through forked tail structural connection on the right-hand member face of kicking block 20. That is, the screw 21 is rotatable with respect to the top block 20 but is not disengageable. And the bottom of the auxiliary hole 13 is provided with a screw hole 131, the screw 21 is screwed in the screw hole 131, and the right end of the screw 21 is positioned outside the right side of the corresponding screw hole 131. The screw 21 is preferably a socket head cap screw.

Thus, when in use, after a fastening screw passes through the corresponding circular fixing hole 121 from right to left, the fastening screw is screwed on the left support plate on the power output shaft of the motor on the grinding machine, and the grinding sheet is clamped between the plate body 10 and the left support plate, so that the normal use of the grinding sheet can be ensured after the clamping. The left support plate is screwed to a flange already provided on the motor power output shaft by a fastening screw with a regular hexagon big end, so that the regular hexagon fixing hole 122 can be used for accommodating the big end of the corresponding fastening screw to prevent the fastening screw from rotating and falling off. When used for a period of time, the clamped portion of the abrasive sheet is most likely to become thinner. At this time, the screw 21 is tightened to move the top block 20 leftward to abut against the right side surface of the grinding chip, thereby continuing to secure the stability of the grinding chip.

Optimizing:

the left end face of the top block 20 is distributed with a plurality of pointed cones 22 protruding leftwards. That is, the tip block 20 has a greater frictional force against the abrasive sheet by the pointed cones 22, further ensuring the stabilization of the abrasive sheet.

The center position of the left end surface of the top block 20 is smooth. That is, the pointed cone 22 does not completely fill the left end face of the top piece 20 to ensure good heat dissipation between the components.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
