Abstract
The utility model discloses one kind to draw horse, including interior steel plate, screw rod, screw mandrel, nut, outer steel plate, there is a centre bore in the center of the interior steel plate, it is available for the screw-in of the screw mandrel, the interior steel plate at outer steel plate outer rim with having outer marginal pore, the screw rod screws in steel plate and outer steel plate in outer marginal pore connection, and screw rod is fixed on interior steel plate and outer steel plate by the nut.The utility model by screw mandrel by penetrating inner hole of workpiece and fixation, apply pressure to take out workpiece, avoiding the occurrence of other triangles draws horse, bipod to draw horse that power is acted on to the situation of the edge of work in dismounting, but power directly is acted on into root, prevents that workpiece is caused to damage.
Description
【Technical field】
A kind of technical field of maintenance of machine instrument is the utility model is related to, particularly a kind of technical field for drawing horse.
【Background technology】
When apparatus is installed and is overhauled, horse is drawn to be commonly used for dismantling the belt pulley in various plant equipment, gear, bearing etc.
Workpiece.It is not when dismantling the objects such as bearing, belt pulley, fixed stop using wider triangle drawing horse and bipod drawing horse at present
Stress point directly acts on to the root of split object, but in its marginal portion, easily cause split object to produce damage.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of drawing horse, can be in disconnecting apparatus and disengaging gear
When split object receiving force point is preferably acted on into its root, so as to the damage for reducing workpiece configuration and outer surface is subject to.
To achieve the above object, horse is drawn the utility model proposes one kind, including it is interior steel plate, screw rod, screw mandrel, nut, outer
There is a centre bore in steel plate, the center of the interior steel plate, are available for the screw-in of the screw mandrel, the interior steel plate with outer steel plate outer rim
Have an outer marginal pore, the screw rod screws in steel plate and outer steel plate in outer marginal pore connection, the nut by screw rod be fixed on interior steel plate with outside
On steel plate.
Preferably, the interior steel plate and outer steel plate are square, and the outer marginal pore in four corners of steel plate is respectively four
It is individual.
Preferably, the interior steel plate is combined by left and right two parts, fixation forms.
Preferably, the size of the interior steel plate, outer steel plate and the length of screw mandrel can dismantle object with being actually needed
Size accordingly changes.
Preferably, the power that the thickness of the screw rod and interior steel plate, the thickness of outer steel plate can be born with being actually needed
Size accordingly changes.
The beneficial effects of the utility model：The utility model applies pressure by the way that screw mandrel is penetrated into inner hole of workpiece and fixation
To take out workpiece, the situation that other triangles draw horse, bipod to draw horse that power is acted on to the edge of work in dismounting is avoided the occurrence of, but
Power is directly acted on into root, prevents that workpiece is caused to damage.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of front view for drawing horse of the utility model；
Fig. 2 is a kind of top view for drawing horse of the utility model.
In figure：Steel plate, 2- screw rods, 3- screw mandrels, 4- nuts, 5- outer steel plate, 11- centre bores in 1-.
【Embodiment】
Refering to Fig. 1, a kind of drawing horse of the utility model, including interior steel plate 1, screw rod 2, screw mandrel 3, nut 4, outer steel plate 5, it is described
There is a centre bore 11 in the center of interior steel plate 1, is available for the screw-in of the screw mandrel 3, the interior steel plate 1 at the outer outer rim of steel plate 5 with having
Outer marginal pore 12, the screw rod 2 screw in outer marginal pore 12 and connect interior steel plate 1 and outer steel plate 5, and screw rod 2 is fixed on interior steel by the nut 4
On plate 1 and outer steel plate 5, the interior steel plate 1 and outer steel plate 5 are square, and the outer marginal pore 12 in four corners of steel plate is respectively
Four, the interior steel plate 1 is combined by left and right two parts, fixation forms, the interior steel plate 1, the size and screw mandrel 3 of outer steel plate 5
Length can accordingly change with the size for being actually needed dismounting object, the thickness and interior steel plate 1 of the screw rod 2, outer steel plate 5
The size for the power that thickness can be born with being actually needed accordingly changes.
Utility model works process：
A kind of centre bore 11 for drawing horse in the course of the work, screw mandrel 3 being passed through to interior steel plate 1 of the utility model, during dismounting in
Between can equipped hydraulic jack, screw mandrel 3 is penetrated into the inner hole of workpiece that bearing, belt pulley etc. need to be dismantled, under pressure, will
Workpiece ejects from the outside of screw mandrel 3.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
