Groove bearing knife is safe.
Technical solutions of the utility model：A kind of grooving bearing knife, including tool apron, blade and briquetting, it is characterised in that：It is described
Tool apron one end is disposed with limiting slot and locating slot；The briquetting is arranged on locating slot, by blade pressing in limiting slot；
The limiting slot both sides are respectively arranged with limited block；The locating slot both sides are respectively arranged with locating piece.
2 anti-grinding outs are additionally provided on aforementioned limiting slot.
Aforementioned locating piece width is 6.25mm, and positioning groove width is 12.5mm, height between the locating piece surface and locating slot
Difference is 2.7mm.
Aforementioned briquetting is matched with locating slot.
Previous insert is triangular blade, and the blade inscribed circle diameter is 15.875mm.
Aforementioned limiting slot is matched with blade.
Aforementioned briquetting is provided with keyway；The briquetting is equipped with inclined-plane, the inclined-plane central axes and institute close to limiting slot one end
It states between briquetting central axes into 60 degree of angles.
Aforementioned grooving bearing knife, further includes edge bearing, and the edge bearing is matched with blade, and the edge bearing is arranged under blade.
Angle between aforementioned limiting slot central axes and tool apron central axes is 9 degree.
Angle between aforementioned locating slot central axes and tool apron central axes is 9 degree.
Compared with prior art, the utility model has done position restriction to briquetting, has pressed by the way that locating slot and limiting slot is arranged
Block is also pressed in limiting slot blade and edge bearing using keyway, improves stability, and also avoiding blade makes to be screwed
And the security risk occurred；And edge bearing and briquetting can also delay the breakage of blade and tool apron when colliding, and reduce
Use cost；And blade is placed in limiting slot, the setting in hole can allow blade to avoid unnecessary abrasion, increase use
Service life also reduces use cost.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Label in attached drawing be：1- tool aprons, 2- blades, 3- briquettings, 4- limiting slots, 5- locating slots, 6- limited blocks, 7- positioning
Block, 8- edge bearings.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples, but is not intended as limiting the utility model
The foundation of system.
Embodiment 1.
A kind of grooving bearing knife, as shown in Figure 1, including tool apron 1, blade 2 and briquetting 3,1 one end of the tool apron is set gradually
There are limiting slot 4 and locating slot 5；The briquetting 3 is arranged on locating slot 5, and blade 2 is pressed in limiting slot 4；The limiting slot
4 both sides are respectively arranged with limited block 6；5 both sides of the locating slot are respectively arranged with locating piece 7.
2 anti-grinding outs are additionally provided on the limiting slot 4.
7 width of the locating piece is 6.25mm, and 5 width of locating slot is 12.5mm, between 7 surface of the locating piece and locating slot 5
Difference in height is 2.7mm.
The briquetting 3 is matched with locating slot 5.
The blade 2 is triangular blade, and 2 inscribed circle diameter of the blade is 15.875mm.
The limiting slot 4 is matched with blade 2.
The briquetting 3 is provided with keyway；The briquetting close to 4 one end of limiting slot be equipped with inclined-plane, the inclined-plane central axes with
At 60 degree of angles between 3 central axes of the briquetting.
The grooving bearing knife further includes edge bearing 8, and the edge bearing 8 is matched with blade 2, and the edge bearing 8 is arranged in blade 2
Under.
Angle between 1 central axes of 4 central axes of the limiting slot and tool apron is 9 degree.
Angle between 1 central axes of 5 central axes of the locating slot and tool apron is 9 degree.
Before use, fetching tool apron 1, blade 2 is placed on limiting slot 4, briquetting 3 is placed on locating slot 5, briquetting 3 is bevelled
One end is placed on close to one end of blade 2, and crush block 3 is positioned against block 7, and briquetting 3 is connect with locating slot 5 by screw, not twisted
Tight screw, according to the size and location of blade 2, mobile briquetting 3 after location determination, is tightening screw, installation is complete.
