Description
Technical field
The utility model belongs to machinery manufacturing technology field more particularly to a kind of manual rotation bearing pin removal.
Background technology
Currently, the workpiece being located by connecting using circular cone positioning pin, cylindrical positioning pins in machinery industry is tearing son point of pulling pin open
During from workpiece, pin removal is commonly used, at this stage there are two types of common pin removals：1. manual pouring weight impact type pin removal,
Its is simple in structure, and manufacturing cost is low, but generates impact force since pouring weight will fast move stroke in operation, need compared with
Big operating space, labor intensity is big during pulling pin, needs repeat impact, and efficiency is low, is easy to happen and damages, scratches operator
The problem of situation；2. ARTMechanical gas pressure（Hydraulic pressure）Formula pin removal, mainly by air pump（Oil pump）, upper cylinder cover, lower cylinder cap, tubular cylinder
Body, pause switch, spring, sliding block and connection bolt composition, complicated, cost is high, moreover, efficiency is relatively low.
Invention content
In order to solve the problems in the existing technology, the purpose of this utility model is to provide a kind of manual rotation bearing and pulls out
Sell device.
In order to achieve the above-mentioned object of the invention, the utility model uses technical solution as described below：
A kind of manual rotation bearing pin removal, including pressurizing nut, thrust bearing, support tube, thread, screw thread plug
And positioning screw, thread are threaded through in support tube, one end end face of thread is provided with internal thread hole, and screw thread plug is
Double threaded screw, one end of screw thread plug are bolted in the internal thread hole and tight by revolving the locking nut set on screw thread plug
Gu the other end of thread stretches out support tube, it is fitted with pressurizing nut on the other end of thread, in nut and support tube
Between be provided with the thrust ball bearing being sleeved on thread, radially offer tapped through hole on the side wall of support tube,
The positioning screw stretches into after passing through tapped through hole in the location hole being arranged on thread, and the location hole is bar shaped slot hole.
Further, the diameter of the spiro rod section of screw thread plug one end is more than the diameter of the spiro rod section of the other end, described
Locking nut is screwed onto on the spiro rod section of the other end of screw thread plug.
Further, one end of the support tube is fixedly connected on the end face of thrust ball bearing.
Further, thread is made of the polished rod and other end screw rod of one end.
Due to the adoption of the above technical scheme, the utility model has following superiority：
The utility model can be extracted pin by rotating pressurizing nut, when specifically used as a result of thrust
Bearing, it is time saving and energy saving when pulling pin, greatly reduce labor intensity, and will not disfiguring workpiece, the utility model has structure
Simply, small, low cost, efficient advantage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1, pressurizing nut；2, thrust bearing；3, support tube；4, screw thread plug；5, positioning screw；6, thread；
7, locking nut.
Specific implementation mode
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of manual rotation bearing pin removal, including pressurizing nut 1, thrust bearing 2, support tube 3, screw thread
Pull rod 6, screw thread plug 4 and positioning screw 5, thread 6 are threaded through in support tube 3, and one end end face of thread 6 is provided with
Internal thread hole, screw thread plug 4 are double threaded screw, and one end of screw thread plug 4 is bolted in the internal thread hole and passes through screw thread
It revolves the locking nut 7 set on plug 4 to fasten, the other end of thread 6 stretches out support tube 3, on the other end of thread 6 matches
Equipped with pressurizing nut 1, the thrust ball bearing 2 being sleeved on thread 6 is provided between pressurizing nut 1 and support tube 3,
Tapped through hole is radially offered on the side wall of support tube 3, the positioning screw 5 stretches into thread 6 after passing through tapped through hole
In the location hole of upper setting, the location hole is bar shaped slot hole.
The diameter of the spiro rod section of described 4 one end of screw thread plug is more than the diameter of the spiro rod section of the other end, the locking nut
It is screwed onto on the spiro rod section of the other end of screw thread plug.
One end of the support tube 3 is fixedly connected on the end face of thrust ball bearing.
Thread 6 is made of the polished rod and other end screw rod of one end.
In the utility model, bolt may be used in the screw thread plug 4, and the head end of bolt is welded in the one of thread
On end face.
Screw thread plug is screwed in the threaded hole of taper bolt or straight pin, is then led to when specifically used by the utility model
Rotation pressurizing nut is crossed, due to the effect of positioning screw so that thread can only be axially moveable, and then drive screw thread plug
Mobile, so that taper bolt or straight pin are pulled out, it is time saving and energy saving that the utility model uses, and it is strong to greatly reduce labour
Degree, and will not disfiguring workpiece, working efficiency can be effectively improved.
