Description
Technical field
The utility model is related to frock technical field, particularly a kind of fitted shaft perforation frock and the dress with the frock
It puts.
Background technology
At present, in heavy mechanical equipment assembling, due to some pts wt weights, school position is difficult to install, and particularly axis is worn
When hole is assembled, due to shaft hole matching precision is higher and need to avoid in assembling process to the damage of part, it is necessary to it is extremely complex and
Stringent operation, this brings great inconvenience for production, largely effects on production efficiency.
Utility model content
In order to overcome the shortcomings of above-mentioned existing frock technology.The utility model proposes a kind of fitted shaft perforation frock and have
The device of the frock.
Technical solution is used by the utility model solves its technical problem：
A kind of fitted shaft perforation frock, including：
Supporting plate, the supporting plate are provided at least a pair of of support base, and the support base includes the ear being oppositely arranged before and after two
Support, bearing, screw bolt and nut, the bearing are placed between two earpieces, and bearing and two earpieces are provided with matched circular hole, institute
State bolt through two earpieces circular hole and bearing circular hole and pass through nut and fix, the bearing outer peripheral edge protrusion earpiece top
End.
Further, the supporting plate corner is provided with 4 threaded holes.
As a kind of improvement of said program, the bearing outer ring is provided with rubber ring.
Further, the bearing is interference fitted with rubber ring.
Another kind as said program improves, and the bearing outer ring is equipped with cylinder, and the cylindrical shape is hollow cylinder,
The cylinder is interference fitted with bearing.
Further, the cylinder outer ring is equipped with rubber ring.
Further, the rubber ring is interference fitted with cylinder.
Further, the rubber ring is made with rubber.
The utility model additionally provides a kind of device with the frock, including above-mentioned frock and the electricity that can be moved back and forth
Moving platform, the frock at least there are two and front and rear be symmetrically fixed on electric platforms；The electric platforms are connected with
For driving the driving device that it is moved back and forth.
Further, the driving device include cylinder, oil cylinder, electronic screw it is any.
Further, the tapping screw hole for fixing tool is provided on the electric platforms.
The beneficial effects of the utility model are：The task difficulty of axis perforation is reduced, needs to adjust repeatedly when reducing operation
The time that bearing is wasted improves production efficiency, and the frock and device are simply light, transport easy to remove.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model mounting structure schematic diagram；
Fig. 2 is the utility model mounting structure top view.
Specific embodiment
Referring to figs. 1 to Fig. 2, a kind of fitted shaft perforation frock of the utility model, including：Supporting plate 1, the supporting plate are provided with
At least a pair of of support base 2, the support base 2 include the earpiece 22, bearing 21, bolt 23 and the nut that are oppositely arranged before and after two
24, the bearing is placed between two earpieces 22, and bearing 21 and two earpieces 22 are provided with matched circular hole, and the bolt 23 is worn
It crosses the circular hole of two earpieces 22 and the circular hole of bearing 21 and passes through nut 24 and fix.The frock is to go to support by the bearing of both sides
The axis assembled is needed, therefore 21 outer peripheral edge of bearing needs to protrude 22 top of earpiece.
In the present embodiment, 1 four jiaos of the supporting plate is provided with 4 threaded holes, is positioned for the installation of entire frock.
Above-mentioned frock can only support shaft sub-fraction, for axis uniform force, it is necessary to multiple frocks dispersedly support shaft
Each position, and frock need ensure at grade.Therefore propose a kind of device, include electric platforms and multiple above-mentioned works
Dress, the frock at least 2 and it is front and rear be symmetrically fixed on electric platforms, corresponding threaded hole is provided on electric platforms
For Matching installation.
During operation, axis is placed in the frock of the device, device needs to move back and forth to complete axis perforation process, therefore at this
Connection can drive the driving device that it is moved back and forth on the electric platforms of device, and driving device can be cylinder, oil cylinder, electronic silk
Bar it is any.When the device band moving axis moves back and forth, it may cause relatively since the frictional force between axis and bearing 21 is too small
It slides, influences operating efficiency, therefore rubber ring is set on the bearing 21 of each frock of device, rubber ring and bearing 21 are interference fitted.
In order to which bearing is not easily damaged, bearing is protected in the cylinder 3 of the outer snare hollow cylinder of bearing 21, of course for anti-skidding also in circle
The rubber ring of interference fit is set on cylinder.So above device can smoothly complete axis perforation process.
Above example is only to illustrate the technical solution of the utility model and is not limited, all without departing from this
Any modification of utility model spirit and scope or equivalent substitution should all cover the scope in technical solutions of the utility model
It is interior.
