Abstract
The utility model discloses an end cover locking structure for a hob with a fixed shaft end. An end cover is connected with a hob shaft by threads; a back nut is screwed in the hob shaft adhering to the outer side of the end cover; and a bolt is connected between the back nut and the end cover. The end cover locking structure is used for the hob with the fixed shaft end, realizes the locking of the end cover on the hob shaft by the friction between the back nut and the side surface of the end cover, further strengthens the locking of the end cover by the bolt between the back nut and the end cover, is characterized with high locking reliability and assembly and disassembly simplicity, and is convenient for manufacturing and renovating the hob.
Description
Technical field
The utility model relates to a kind of locking mechanism, especially a kind of fixing hobboing cutter end cap locking mechanism of axle head that is used for.
Background technology
When shield machine tunnels at pure ground consisting of hard rock, adopt hobboing cutter to break rock, the principle of the broken rock of hobboing cutter is to rely on cutter to roll to produce the impact crushing and shear the purpose that the effect of pulverizing reaches fractured rock more.
All need when the manufacturing of hobboing cutter and renovation end cap is dismantled and installed; Though end cap Type of Welding commonly used has the firm characteristics of locking; But it obviously has not easily detachable characteristics, for increasing hobboing cutter assembling and renovation efficient, needs a kind of better retaining mechanism.
The utility model content
The purpose of the utility model provides the fixing hobboing cutter end cap locking mechanism of a kind of axle head, and it not only has good end cap locking effect, and convenient for assembly and dismounting.
The purpose of the utility model realizes through following technical scheme:
The hobboing cutter end cap locking mechanism that a kind of axle head is fixing, end cap is threaded with the cutter shaft employing, is close on the outside cutter shaft of end cap to screw in back tightening nut, is connected with bolt between said back tightening nut and the said end cap.
Further, said back tightening nut is positioned at the groove of end cap side.
Further, said bolt passes the bolt hole that the deep-slotted chip breaker screw terminal that is positioned on the back tightening nut covers.
The described end cap locking mechanism of the utility model; Be used for the fixing hobboing cutter of axle head; Frictional force through back tightening nut and end cap side realizes the locking of end cap on cutter shaft, and further further strengthens through bolt between the two, and it is high to have reliable lock property; Be easy to the characteristics assembling and dismantle, made things convenient for the manufacturing and the renovation of hobboing cutter.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the hobboing cutter structural representation that adopts the said retaining mechanism of the utility model;
Fig. 2 is the right view of Fig. 1.
Among the figure: 1, cutter shaft; 2, blade; 3, hobboing cutter shell; 4, left side end cap; 5, right side end cap; 6, bearing; 7, back tightening nut; 8, bolt; 9, deep-slotted chip breaker.
The specific embodiment
To shown in Figure 2, provided the hobboing cutter structural representation that uses the said retaining mechanism of the utility model like Fig. 1, this hobboing cutter is made up of cutter shaft 1, blade 2, hobboing cutter shell 3, bearing 6, left side end cap 4 and right side end cap 5; Each parts is installed by the right side of cutter shaft 1 during assembling; Right side end cap 5 adopts with cutter shaft 1 and is threaded, and after it screws on the cutter shaft 1, is close to the outside of right side end cap 5; Back tightening nut 7 is screwed on the cutter shaft 1; Realize that the right side end cap 5 and back tightening nut 7 back of the body between the two are tight, at last bolt 8 is passed the bolt hole on the deep-slotted chip breaker 9 screw-in right side end caps 5 that are positioned on the back tightening nut 7, both are fixing once more; Back tightening nut 7 is positioned at the groove of right side end cap 5 sides, makes structure more compact.
