Description

The guide frame of lathe headstock counter-balanced heavy hammer

Technical field

The utility model belongs to the technical field of machine tool, relates to the heavy type numerical control lathe of metal cutting, and more particularly, the utility model relates to a kind of guide frame of lathe headstock counter-balanced heavy hammer.

Background technology

The NC heavy floor type boring and milling machine is in process, and the main spindle box of lathe is done vertical upper and lower motion on the column guide rail.

Structure as shown in Figure 1; Weight for the balancing main shaft casing; The normal counter-balanced heavy hammer 13 that adopts is come balance; Described counter-balanced heavy hammer 13 is generally carried out underslung the connection through pulley and wirerope mechanism with main spindle box, makes that column 1 is no longer one-sided to be received the moment of flexure effect and occur bending and deformation, so column 1 effect that only is under pressure.And the variation of the position of the location following main spindle box of counter-balanced heavy hammer 13 in column 1 moves up and down, because be to be suspended on the column 1 by wirerope, so beat, bump take place easily, needs to control with the employing guider.

The guide frame of prior art is: in the weight of counter-balanced heavy hammer 13 hour, adopts two guiding angle bar 17 to lead, limit the beat of counter-balanced heavy hammer 13 and prevent the bump of counter-balanced heavy hammer 13 columns 1.

But when, counter-balanced heavy hammer big at the main shaft casing 13 was heavier, because guiding angle bar 17 is bigger with the gap between the counter-balanced heavy hammer 13, particularly in the moment of electric motor starting, the position of counter-balanced heavy hammer 13 is generation beat easily still, thereby clashes into.

The utility model content

The utility model provides a kind of guide frame of lathe headstock counter-balanced heavy hammer, its objective is the beat phenomenon of eliminating counter-balanced heavy hammer, avoids the bump of column.

To achieve these goals, the technical scheme taked of the utility model is:

The guide frame of the lathe headstock counter-balanced heavy hammer that the utility model provided; Described counter-balanced heavy hammer is located in the column; And be connected with lathe headstock through pulley mechanism, be provided with two settings, columniform guide post in the described column, be located at the both sides of described counter-balanced heavy hammer; A directive wheel that has arc groove is respectively established in the upper and lower of each side of described counter-balanced heavy hammer both sides, and described directive wheel is a roller, and described arc groove forms to roll with described guide post external cylindrical surface and cooperates.

On described counter-balanced heavy hammer one side, on the holder of right two directive wheels, respectively be provided with two secondary dish springs, its action direction is to make described directive wheel press to described guide post.

Described guide post is fixedly mounted on the described column through fairlead, and between described column and fairlead, is provided with adjusting pad.

The utility model adopts technique scheme; Not only can adjust the gap between counter-balanced heavy hammer and the guide post, and the vibration can reduce to move the time, the counter-balanced heavy hammer that the has solved heavy machine tool problem that accurately leads; Make its motion steadily, improve the machining accuracy of lathe.

The specific embodiment

Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.

Structure like the expressed the utility model of Fig. 2, Fig. 3 is a kind of guide frame of lathe headstock counter-balanced heavy hammer, and described counter-balanced heavy hammer 13 is located in the column 1, and is connected with lathe headstock through pulley mechanism.

In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize eliminating the beat phenomenon of counter-balanced heavy hammer, avoid the goal of the invention of the bump of column, the technical scheme that the utility model is taked is:

As shown in Figures 2 and 3, the guide frame of the lathe headstock counter-balanced heavy hammer that the utility model provided is provided with two settings, columniform guide post 4 in the described column 1, be located at the both sides of described counter-balanced heavy hammer 13; A directive wheel 5 that has arc groove is respectively established in the upper and lower of each side of described counter-balanced heavy hammer 13 both sides, and described directive wheel 5 is a roller, and described arc groove forms to roll with described guide post 4 external cylindrical surfaces and cooperates.

In actual processing and manufacturing and production process, for addressing the above problem, the utility model adopts servicing unit to lead.Centre in counter-balanced heavy hammer 13 two sides, a directive wheel 5 that has arc groove is respectively adorned in the top on left upper portion, bottom, right side, bottom, is partly containing guide post 4 and is leading.Feasible slip becomes rolling; Also make the gap between the guide frame greatly reduce, particularly under situation very close to each other, that push down by elastic force, counter-balanced heavy hammer 13 can freely be moved up and down; Can overcome the beat phenomenon of counter-balanced heavy hammer 13, avoid the bump of column.

On described counter-balanced heavy hammer 13 1 sides, on the holder 7 of right two directive wheels 5, respectively be provided with two secondary dish springs 11, its action direction is to make described directive wheel 5 press to described guide post 4.

Like Fig. 2, shown in Figure 3, at the holder upper left, the bottom right of counter-balanced heavy hammer 13 two secondary dish springs 11 are respectively arranged for 7 times, not only can adjust the gap between counter-balanced heavy hammer 13 and the guide post 4, and the vibration can reduce to move the time.The counter-balanced heavy hammer that this guider the has solved heavy machine tool problem that accurately leads makes its motion steadily, improves machine tool accuracy.

The mounting means of guide frame:

Described guide post 4 is fixedly mounted on the described column 1 through fairlead 3, and between described column 1 and fairlead 3, is provided with adjusting pad 2.

The effect of adjusting pad 2 is gaps of regulating between guide post 4 and the directive wheel 5, leans on the elastic reaction of dish spring 11 to eliminate the gap at last, and produces an elastic compression power.

Directive wheel 5 is installed on the little axle 9 through bearing 14 and spacer 15, and described little axle 9 ring flanges 8 through the end are installed on described holder 7 or the holder 16.

In the left side of Fig. 3, described dish spring 11 is installed on the counter-balanced heavy hammer 13 through screw rod 10, and with locking nut 6 lockings; In dish spring 11 and counter-balanced heavy hammer 13 pad 12 is set also, further regulates the elastic compression power between guide post 4 and the directive wheel 5 through pad 12.

Certainly, the right side in the left side of Fig. 3 no longer need be provided with dish spring 11, holder 16 direct fastening being installed on the counter-balanced heavy hammer 13.Because the effect of the dish spring 11 in left side, the guide post 4 and the directive wheel 5 on right side still are elastic compression power.

Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
