Abstract
The utility model relates to the technical field of coal mine mechanical assembly, in particular to a clamping block special for fastening a bolt of a hammerhead of a crusher. When the assembled hammerhead screws down the bolt, a hammer body is casted, and thus, the pattern draft and the circular arc on the hammer body make an original counter torque clamping block not find the acting point; in the screwing process, the condition that an iron plate of a cushion is squeezed out always occurs when a mode of cushioning the iron plate is adopted; and the conventional clamping block has potential safety hazard and is inconvenient to operate. The clamping block special for fastening the bolt of the hammerhead of the crusher is characterized in shape and structure in that a left surface part of the special clamping block is of a square shape; the width of a frame of the left surface part corresponds to the width of a casting groove at the position at where the hammer body fastens the bolt; the diameter of a center round hole of the left surface part corresponds to the outside diameter of a socket of an electric wrench; a right surface part of the clamping block is of a hook shape and is provided with an inclined plane; the middle of the right surface part is provided with a groove; the angle alpha of the inclined plane is between 15 and 20 degrees; the width of the inclined plane corresponds to the width of the lateral surface of the counter torque clamping block of the electric wrench; and the thickness of the special clamping block corresponds to the height of the socket of the electric wrench. The utility model has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model relates to coal mine machinery mounting technology field, the special-purpose fixture block of specifically a kind of grinder hammerhead bolted.
Background technology
In recent years for solve ore deposit side in use disintegrating machine fall the tup problem, use German import electrokinetic moment spanner, make the screw-down torque of the bolt of tup can reach designing requirement substantially, solved and fallen the tup problem in the use of ore deposit side, but when the assembling tup tights a bolt, because the profile space of hammer body casts, pattern draft and circular arc on the hammer body make original countertorque fixture block, can not find impetus, mode with the parallels plate, in rundown process, iron plate the squeezing that pad often takes place flies situation, and the people easily injures, have potential safety hazard, operation is also inconvenient.
Summary of the invention
The purpose of this utility model provides the special-purpose fixture block of a kind of grinder hammerhead bolted, to solve the above-mentioned problems in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: according to grinder hammerhead and hammer body attachment bolt place locus shape and electric wrench countertorque size design one special-purpose fixture block, its shape and structure are: special-purpose fixture block left part is square, outer width of frame is corresponding with the casting well width at hammer body fastening bolt place, and the middle circle bore dia is corresponding with electric wrench sleeve outside diameter; Special-purpose fixture block right part is hook-shaped for the band inclined-plane, and bevel angle α is 15～20 °, and surface width is corresponding with the lateral width of electric wrench countertorque fixture block, and there is a groove centre; The thickness of special-purpose fixture block is corresponding with electric wrench sleeve height.
The utility model beneficial effect is: utilize circular hole on the special-purpose fixture block and the casting groove on the hammer body can make personality card piece being stuck on the hammer body steadily, electric wrench countertorque side is flattened on the fixture block inclined-plane, so just can make the electric wrench countertorque find impetus, the bolt on the fastening tup of safe ready by special-purpose fixture block.Eliminate and in use have personal safety and equipment breakdown hidden danger.This personality card block structure is simple, but easy to operate and extensive use.

The specific embodiment
Among the figure: 1. bolt, 2. pressing plate, 3. hammer body, 4. tup, 5. sleeve, 6. special-purpose fixture block, 7. spanner, 8. countertorque fixture block.
Special-purpose fixture block 6 left part are square, and outer width of frame is corresponding with the casting well width at hammer body 3 fastening bolts 1 place, and the middle circle bore dia is corresponding with electric wrench sleeve 5 outside diameters; Special-purpose fixture block 6 right part are hook-shaped for the band inclined-plane, and bevel angle α is 15～20 °, and surface width is corresponding with the lateral width of electric wrench countertorque fixture block 8, and there is a groove centre; The thickness of special-purpose fixture block 6 is corresponding with electric wrench sleeve height.
Special-purpose fixture block 6 each seamed edge are processed with fillet, and the chamfering at the left side and top is 10 * 45 °～20 * 45 °.
The outer width of frame of above-mentioned special-purpose fixture block 6 is corresponding with the casting well width at hammer body 3 fastening bolts 1 place, the outer width of frame that is meant special-purpose fixture block 6 is to determine by the casting well width at hammer body 3 fastening bolts 1 place, special-purpose fixture block 6 can be put to the casting groove of hammer body 3; Other that occurs in the utility model " corresponding " all is like this.
The personality card of the utility model design is to cooperate electric wrench (comprising sleeve 5, spanner 7 and countertorque fixture block 8) soon, electric wrench countertorque side is flattened on the fixture block inclined-plane, so just can make the electric wrench countertorque find impetus, the bolt on the fastening tup of safe ready by special-purpose fixture block.
Shown in Fig. 3～8, during work, with bolt 1, pressing plate 2 connects tup 4 with hammer body 3, interior hexagonal hole correspondence with sleeve 5 is put on the hex nut of bolt 1 then, special-purpose fixture block 6 is put to the casting groove of hammer body 3, and the middle circle borehole jack on the special-purpose fixture block 6 on the sleeve on the electric wrench 5, again internal square hole spanner 7 is enclosed within on the outer square head of sleeve 5 upper ends, and rotating spanner 7, the side of the countertorque fixture block 8 of electric wrench is flattened on the inclined-plane of special-purpose fixture block 6, the impetus of a safety and stability so just is provided for the countertorque fixture block 8 of electric wrench, makes the fastening bolt 1 that spanner 7 can safe ready, reach requirement moment.
