Abstract
The utility model discloses a device convenient to pressure equipment axle box, including wheel pair, axle box and under -floor wheel lathe, under -floor wheel lathe is still including pressing claw and friction wheel carrier, is provided with the axle box in wheel pair bilateral symmetry position, and the axle box top is provided with the pressure claw, is provided with the friction wheel carrier in the wheel pair below, is provided with and presses the pressure equipment position of claw contact in the axle box top, and the pressure equipment position be horizontal structure, with the pressure claw at the coplanar. The device of this kind of pressure equipment axle box changes the circular structure at the pressure equipment position of under -floor wheel lathe and axle box into horizontal structure, is convenient for press the claw to carry out the pressure equipment to the pressure equipment position of axle box, has improved packing force between the two, has ensured reliability and security that the wheel pair examined and repaired the in -process.
Description
Technical field
This utility model belongs to the wheel set maintenance technical field of rail locomotive and rail vehicle, and in particular to one kind is easy to pressure
The device of dress axle box.
Background technology
With developing rapidly for track traffic, rail locomotive and rail vehicle wheel to by distance travelled and operating speed because
Impact its abrasion loss of element is constantly aggravated, in the past to during wheel set maintenance using will wheel pair and bogie and car body by the way of lifting
Separate, in recent years, with the continuous progress of technology, a kind of numerical control lathe used for machining in-situ locomotive wheel is widely used in wheel set maintenance, save
Cost and the repair time is shortened, lathe used for machining in-situ locomotive wheel paw is contacted with axle box and press-fited, the axle box of existing locomotive and vehicle and not
Fall to taking turns lathe paw contact site for arc structure, and lathe used for machining in-situ locomotive wheel paw contact surface is horizontal structure, both contact surfaces compared with
It is little easily to make obscission occur during wheel set maintenance, make troubles to maintenance.
Utility model content
This utility model is in order to solve above-mentioned technical problem, there is provided a kind of device for being easy to press-fit axle box.
The technical scheme that this utility model is adopted is：A kind of device for being easy to press-fit axle box, including wheel is to, axle box and not
Fall to taking turns lathe；Lathe used for machining in-situ locomotive wheel includes paw and friction wheel carrier, axle box is fixedly connected with to both sides symmetric position in wheel, on axle box
Side be provided with contact with paw press-fit position, press-fit and be provided with position paw, paw basal sliding be connected to non-pulling wheel revolve
On bed, non-pulling wheel lathe bottom centre position is provided with friction wheel carrier.
Press-fit position for horizontal structure.
Take turns the quantity to, paw and friction wheel carrier and be 2, and symmetrically.
It is this be easy to press-fit axle box device use process be：The paw of lathe used for machining in-situ locomotive wheel is pushed down into axle box, paw is countershaft
Case applies downward pressure, rises friction wheel carrier, to wheel to applying a support force upwards, coordinates the V-type positioning of roller, enters
And realize to wheel to radial compaction.
The beneficial effects of the utility model：The arc structure for press-fiting position of lathe used for machining in-situ locomotive wheel and axle box is changed to into horizontal junction
Structure, is easy to paw to press-fit the position that press-fits of axle box, improves thrust between the two, has ensured wheel set maintenance process
In reliability and safety.
Description of the drawings
Fig. 1 is assembling structure schematic diagram of the present utility model；
Fig. 2 is axle box front view of the present utility model；
Labelling in figure：1st, take turns right, 2, axle box, 3, lathe used for machining in-situ locomotive wheel, 4, paw, 5, friction wheel carrier, 6, press-fit position.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
As illustrated, a kind of device for being easy to press-fit axle box, including wheel is to 1, axle box 2 and lathe used for machining in-situ locomotive wheel 3；Non-pulling wheel Xuan
Bed 3 includes paw 4 and friction wheel carrier 5, and in wheel axle box 2 is fixedly connected with to 1 both sides symmetric position, the top of axle box 2 be provided with
What paw 4 was contacted press-fits position 6, press-fits and paw 4 is provided with position 6, and the basal sliding of paw 4 is connected on lathe used for machining in-situ locomotive wheel 3,
The bottom centre position of lathe used for machining in-situ locomotive wheel 3 is provided with friction wheel carrier 5.
Press-fit position 6 for horizontal structure.
Take turns and 2 is to the quantity of 1, paw 4 and friction wheel carrier 5, and symmetrically.
It is this be easy to press-fit axle box device use process be：The paw 4 of lathe used for machining in-situ locomotive wheel 3 is pushed down into axle box 2, paw 4
Apply downward pressure to axle box 2, rise friction wheel carrier 5, a support force upwards is applied to 1 to wheel, coordinate the V-type of roller
Positioning, and then realize the radial compaction to wheel to 1.
