Abstract
A kind of top cylinder piston rod fixed structure of vertical gear hobber, it is characterised in that：Including fixture block, fastening bolt, "u"-shaped groove is provided on fixture block, fixture block one end is linked into an integrated entity with original dismounting flat on interference fit type seized piston bar, the other end with dead head body with fastening bolt.The utility model structure fixture block clamps down on the dismounting flat on piston rod and passes through fastening bolt and is fixed on dead head by "u"-shaped groove, so as to achieve the purpose that prevent piston rod from loosening rotation, it can thoroughly prevent piston rod thread repeatedly after stress, loosening rotation on dead head, the final security risk solved under dead head landing is pounded.
Description
Technical field
The utility model is related to a kind of top cylinder piston rod fixed structures of vertical gear hobber.
Background technology
The upper top tip structure assembly of vertical gear hobber is usually hung down by the top oil cylinder connection dead head on post with top
Straight installation composition.Oil cylinder by external hydraulic power drive dead head, it is top move up and down along guide rail, realize and be processed production
Product hold out against and loosen.To ensure the personal safety of the positioning accuracy of work piece and operative employee.It is total to must be prevented from top tip structure
Into during the motion, there is loose phenomenon with dead head in drive cylinder, is pounded down in order to avoid dead head is caused to come off, lead to equipment,
The security incident of employee.At present, vertical gear hobber dead head and the conventional connection fastener means of drive cylinder are to use oil cylinder piston
Top pedestal is threaded on bar, then is aided with the connection fastening means of fastening screw nut.When the screw thread of piston rod and dead head connects
Socket part position was worked in axially loaded repeatedly after certain cycle, and piston rod and fastening screw nut can gradually appear loose phenomenon, once
Piston rod completely from dead head rotational release when, dead head, which will come off, to be pounded down, and potential security incident is brought to equipment, employee.
Find in time and prevent piston rod and the screw thread of dead head, fastening screw nut whether there is so must examine by operative employee's everyday devices point
Loosen sign.Dead head oil cylinder is typically mounted at the top of equipment, also has anti-bits shield to surround, and point inspection work adds operative employee's
Auxiliary time of production reduces the utilization rate of equipment.
The content of the invention
The purpose of this utility model is to provide a kind of top cylinder piston rod fixed structures of vertical gear hobber, overcome former knot
The structure equipment point-detecting time is long, dead head can loosen at piston rod connection screw thread and slide pound under the shortcomings that.
A kind of top cylinder piston rod fixed structure of vertical gear hobber, it is characterised in that：Including fixture block, fastening bolt, card
Be provided with "u"-shaped groove on block, fixture block one end with original dismounting flat on interference fit type seized piston bar, the other end with it is top
Seat body is linked into an integrated entity with fastening bolt.
The utility model has the advantages that：The utility model structure fixture block clamps down on the dismounting on piston rod by "u"-shaped groove
Flat simultaneously passes through fastening bolt and is fixed on dead head, so as to achieve the purpose that prevent piston rod from loosening rotation, can thoroughly prevent
For piston rod thread repeatedly after stress, the loosening rotation on dead head, final solution dead head slides the security risk under pounding.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the cross-sectional view of Fig. 1.
In figure：Piston rod 1, dead head 2 dismantle flat 3, fastening screw nut 4, fixture block 5, fastening bolt 6.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of top cylinder piston rod fixed structure of vertical gear hobber, it is characterised in that：Including fixture block 5, fastening bolt 6,
"u"-shaped groove is provided on fixture block 5,5 one end of fixture block is with original dismounting flat 3, the other end on interference fit type seized piston bar
It links into an integrated entity with 2 body fastening bolt 6 of dead head.Piston rod 1 is screwed in dead head 2 and tightens and adjust dismounting flat 3 and is hung down
Directly towards the long extreme direction of top pedestal, while fastening screw nut 4 and tightly, then the dismounting 5 "u"-shaped groove seized piston bar 1 of fixture block
Flat 3, the other end are close to 2 body of dead head and pass through the fastening completion of fastening bolt 6.It is clamped down on and lived by the "u"-shaped groove of fixture block 5
Dismounting flat 3 on stopper rod 1, then fixture block 5 is fixed on by fastening bolt 6 on dead head 2, it is therefore prevented that piston rod 1 loosens rotation
Turn, piston rod 1 and dead head 2 are firmly connected into an entirety by fixture block 5.It ensure that piston rod 1 is threadedly coupled with dead head 2
Connection reliability of the mode in axial movement under force repeatedly.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then should be considered as belonging to the protection domain that claims that the utility model is submitted determine.
