Description
Technical field
The present invention relates to a kind of press-loading apparatus of railway locomotive wheel, particularly a kind of press-loading apparatus of railway locomotive wheel connecting pin.
Background technology
According to practical demand, a lot of rolling stocks need press-fit its wheel connecting pin.The traditional fit of connecting pin is after putting it in the liquid nitrogen cooling, uses sledgehammer that it is knocked in the wheel pin-and-hole through manpower.This assembly technology production efficiency is low, and labour intensity is big, is prone to cause during operator's misoperation the wheel pin-and-hole to pull and the tired defective of impacting of connecting pin root in addition.
Summary of the invention
Technical problem to be solved by this invention is; Not enough to prior art; Be the current demand of satisfying that wheel connecting pin to railway locomotive accurately press-fits and a plurality of connecting pins of wheel being press-fited; Provide a kind of simple in structure, practical and convenient, have the wheel connecting pin press-loading apparatus of good maintainability and operability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of wheel connecting pin press-loading apparatus, comprise base, line slideway and press-mounting platform, and wherein, said line slideway is installed on the base; Described press-mounting platform can move on line slideway, and press-mounting platform is provided with at least two locating pieces and support platform; Described locating piece is provided with the guide frame that support platform moves up and down, and on the described support platform roller is set, and support platform is connected with the support platform lowering or hoisting gear.
As preferred embodiment, described support platform lowering or hoisting gear comprises hollow hydraulic cylinder and air-driven hydraulic pump, and the hollow hydraulic cylinder is connected with air-driven hydraulic pump; Described support platform also is provided with the hydraulic cylinder positioning sleeve that is used to hold the hollow hydraulic cylinder.
Particularly, described guide frame is for being provided with the spill draw-in groove perpendicular to support platform in the inboard of locating piece, and the convexity that is slidingly matched at support platform setting and spill draw-in groove
In order to guarantee the levelness requirement of press-mounting platform on the wheel connecting pin press-loading apparatus base, described base also is provided with arrangement for adjusting height, is used for the height of base is regulated, thereby can makes the maintenance level of press-mounting platform on the base.
Compared with prior art; The beneficial effect that the present invention had is: through line slideway press-mounting platform is moved; Can be easily the press-mounting platform that is loaded with wheel be placed under the forcing press; Location through locating piece can make forcing press that the wheel connecting pin is press-fited accurately, goes up and down to make that through support platform the wheel that has press-fited a connecting pin can rotate to the position that another need press-fit, to realize press-fiting of a plurality of diverse location connecting pins of same wheel.Wheel connecting pin press-loading apparatus disclosed by the invention is simple in structure, and easy to use have good maintainability and an operability, greatly reduces operator's labour intensity, improved connecting pin assembly quality and production efficiency.
Description of drawings
Fig. 1 is the vertical view of one embodiment of the invention.
Fig. 2 is the lateral plan of one embodiment of the invention.
Among the figure, 1, base, 2, line slideway, 3, press-mounting platform, 4, locating piece, 5, support platform, 6, the hydraulic cylinder positioning sleeve, 7, the spill draw-in groove of locating piece, 8, roller, 9, the hollow hydraulic cylinder, 10, air-driven hydraulic pump, 11, the adjustment piece, 12, the adjustment screw rod.
The specific embodiment
Shown in Fig. 1-2, one embodiment of the invention, line slideway 2 be arranged on base 1 above.Press-mounting platform 3 is arranged on the line slideway 2, and can on line slideway, move.Press-mounting platform 3 is provided with the support platform between symmetrical in twos four locating pieces 4 and the locating piece.Locating piece 4 realize to the location of the wheel that will press-fit.The guide frame that moves up and down as support platform 5; The inboard of locating piece 4 also is provided with the spill draw-in groove 7 perpendicular to support platform 5; And support platform 5 is provided with the convexity that is slidingly matched with locating piece 4 inboard spill draw-in grooves 7, makes support platform 5 to move up and down along spill draw-in groove 7 directions.Also have four rollers 8 that are arranged on the same horizontal plane on the support platform 5.The support platform lowering or hoisting gear comprises hollow hydraulic cylinder 9 and air-driven hydraulic pump 10 in the present embodiment, and hollow hydraulic cylinder 9 is connected with air-driven hydraulic pump 10.Support platform 5 also is provided with the hydraulic cylinder positioning sleeve 6 that holds hollow hydraulic cylinder 9.
In addition, base 2 also is provided with arrangement for adjusting height adjustment piece 11 and adjustment screw rod 12, and is as shown in Figure 1.Through regulating adjustment piece 11 and adjustment screw rod 12, can make press-mounting platform 3 maintenance levels on the base, thereby guarantee the levelness requirement of press-mounting platform on the wheel connecting pin press-loading apparatus base.
Press-fit in the process at the wheel connecting pin, at first wheel be placed on the press-mounting platform 3, through locating piece 4 to its location.Under then press-mounting platform 3 being moved to forcing press along line slideway 2, connecting pin is pressed into installing hole through forcing press.After accomplishing the press-fiting an of connecting pin, make hollow hydraulic cylinder 9 that support platform 5 is up pushed up through air-driven hydraulic pump 10.Support platform 5 can move up along guide frame spill draw-in groove 7 directions, and when moving to correct position, wheel breaks away from locating piece 4.At this moment, wheel makes wheel to be adjusted to the correct position that the next one need press-fit connecting pin through the rolling of roller 8.To air-driven hydraulic pump 10 pressure releases, support platform 5 is moved down along guide frame spill draw-in groove 7 directions then, wheel through forcing press connecting pin is press-fited, and the rest may be inferred after falling once more and being fixed on the locating piece, accomplishes press-fiting of all connecting pins of wheel.
