Description
Technical field
The utility model is related to a kind of positioning tool, and more particularly to a kind of motor train unit bogie positions work with bushing bore
Dress.
Background technology
Motor train unit bogie MC nylon bush is loaded and unloaded hole machined and is positioned using traditional drilling tool v block, after positioning
Fixed by operating personnel's manual pressure and drilled.Operationally, because manual pressure is positioned, bushing is not easily because fixation occurs tightly
Hole machined positioning is inaccurate, while product is rocked on v block and causes aperture to be deviateed；Secondly because product is hollow sleeve pipe
Type, product side is subject to the downward pressure of drill bit during drilling, causes product external diameter and internal diameter size to diminish on the direction of drilling,
Vertical direction becomes big size distortion problem.
The content of the invention
Regarding to the issue above, the purpose of this utility model is to provide one kind and can improve hole positioning precision and reduce bushing chi
The bushing bore positioning tool of very little deformation.
To achieve the above object, the utility model uses following technical scheme：A kind of bushing bore positioning tool, its feature
It is：It includes pedestal, riser, hole machined positioning tire and baffle plate；The riser is vertical with the pedestal to be fixedly connected；The hole
Locating and machining tire is respectively arranged with the cylindrical structure of screw rod for two ends, and the screw rod of described hole machined positioning tire one end is passed through
The riser and by the first nut check, the hole machined positioning tire other end the screw rod is through the baffle plate and passes through
Second nut check；The axial direction with the cylindrical structure is offered on the cylindrical structure of hole machined positioning tire
Vertical radial direction through hole.
The length of the length less than bushing to be processed of the cylindrical structure of the hole machined positioning tire.
Packing ring is provided between the riser and first nut and the baffle plate and second nut.
The axis of the radial direction through hole on the hole machined positioning tire is perpendicular to the pedestal.
Also by positioning pin connection between the riser and hole machined positioning tire.
The center line of the through hole passed through for the screw rod on the riser is to riser bottom surface distance more than or equal to 3cm.
Due to taking above technical scheme, it has advantages below to the utility model：1st, the utility model is by riser, gear
Plate is connected with hole machined positioning tire nut check, realizes the end face positioning to bushing, it is possible to increase hole positioning precision.2nd, this practicality
Novel hole locating and machining tire is respectively arranged with the cylindrical structure of screw rod using two ends, and bushing is enclosed within cylindrical structure, cylinder
Body structure plays radial support effect in bushing bore, can reduce liner size deformation.3rd, the utility model is in hole machined
Radial direction through hole is opened up on the cylindrical structure for positioning tire, it is possible to increase the machining accuracy in hole positioning precision and aperture.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the generalized section that the utility model hole machined positions tire；
Fig. 3 is that the utility model machines Workpiece structure schematic diagram.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the utility model includes pedestal 1, riser 2, hole machined positioning tire 3 and baffle plate 4.Riser 2 with
Pedestal 1 is vertically fixedly connected.Hole machined positioning tire 3 is respectively arranged with the cylindrical structure of screw rod, hole machined positioning tire 3 for two ends
The screw rod of one end is locked through riser 2 and by nut 6, and the screw rod of the hole machined positioning other end of tire 3 is through baffle plate 4 and by spiral shell
Female 7 lock.The axially vertical radial direction through hole with cylindrical structure is offered on the cylindrical structure of hole machined positioning tire 3.
Further, the length of the length less than bushing to be processed of the hole machined positioning cylindrical structure of tire 3.
Further, packing ring, device to hole locating and machining are provided between riser 2 and nut 6 and baffle plate 4 and nut 7
Tire plays a part of double locking.
Further, hole machined positions the axis of the radial direction through hole on tire 3 perpendicular to pedestal 1, in order to drilling operation.
Further, also connected by alignment pin 5 between riser 2 and hole machined positioning tire 3, hole machined is positioned tire 3 not
Can rotate, it is ensured that the perpendicularity of radial direction through hole and pedestal 1 on hole machined positioning tire 3.
Further, the center line of the through hole for being passed through for screw rod on riser 2 is more than or equal to 3cm to the bottom surface of riser 2 distance, with
Ensure enough processing spaces.
As shown in figure 1, use process of the present utility model is as follows：First, pedestal 1 is vertically fixedly connected with riser 2, then
The level of pedestal 1 is fixedly connected on workbench.Secondly, hole machined positions the locking of nut 6 of tire 3 and is connected on riser 2, hole
The end face of the cylindrical structure of locating and machining tire 3 is fitted with the side of riser 2, then bushing 8 is set into the circle that hole machined positions tire 3
On column structure, cylindrical structure plays radial support effect to bushing, and the end face of bushing 8 is fitted with the side of riser 2.Again,
Baffle plate 4 is locked with nut 7 and is connected on hole machined positioning tire 3, the side of baffle plate 4 is fitted with the other end of bushing 8, to bushing 8
Play axial restraint effect.Frock assembling is finished, you can is carried out bushing 8 and is drilled (as shown in Figure 3).
The utility model is only illustrated with above-described embodiment, and the structure of each part, set location and its connection are all can
With what is be varied from.It is all individual part is carried out according to the utility model principle on the basis of technical solutions of the utility model
Improvement or equivalents, should not exclude outside protection domain of the present utility model.
