Abstract
本实用新型涉及煤矿机械装配技术领域，具体地说是一种破碎机锤头螺栓紧固专用卡块。在组装锤头拧紧螺栓时，由于锤体是铸造的，锤体上拔模斜度和圆弧，使原有的反力矩卡块，找不到着力点，用垫铁板的方式，在拧紧过程中，经常发生垫的铁板挤飞情况，存在安全隐患，操作不方便。本实用新型的形状及结构特征是：专用卡块左面部分为方形，外框宽度与锤体紧固螺栓处的铸造槽宽度相对应，中间圆孔直径与电动扳手套筒外圆直径相对应；专用卡块右面部分为带斜面的勾形，中间有凹槽，斜面角度α为15～20°，斜面宽度与电动扳手反力矩卡块的侧面宽度相对应；专用卡块厚度与电动扳手套筒高度相对应。本实用新型结构简单，操作方便。
The utility model relates to the technical field of coal mine machinery assembly, in particular to a special clamping block for fastening hammer head bolts of a crusher. When assembling the hammer head and tightening the bolts, since the hammer body is cast, the draft angle and circular arc on the hammer body make the original counter torque block unable to find the point of force. In the process, the iron plate of the mat often squeezes and flies, which poses a safety hazard and is inconvenient to operate. The shape and structural features of the utility model are: the left side of the special block is square, the width of the outer frame corresponds to the width of the casting groove at the fastening bolt of the hammer body, and the diameter of the middle hole corresponds to the outer diameter of the electric wrench sleeve; The right side of the special block is a hook shape with a bevel, with a groove in the middle, the bevel angle α is 15-20°, the width of the bevel corresponds to the side width of the electric wrench counter torque block; the thickness of the special block is the same as that of the electric wrench socket corresponding to the height. 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.
