Abstract
The utility model discloses a lathe tailstock height adjusting device which comprises a lathe tailstock body, wherein a sleeve is arranged in the lathe tailstock body and a screw rod is arranged inside the sleeve; the device is characterized in thinside the sleeve is connected to the screw rod, an eccentric bushing is arranged in the sleeve and has a cylindrical outer surface and a conoid inner surface, a cylindrical axle center deviates from a conoid axle center, and a cone is arranged in the eccentric bushing which is fixed with the sleeve through a bolt and a positioning taper pin. By arranging the eccentric bushing, the rotation position of the eccentric bushing can be adjusted dynamically to change the height of the sleeve. The utility model has the advantages of simple structure, convenient adjustment and high accuracy.
Description
Technical field
The utility model relates to a kind of arrangement for adjusting height, especially relates to a kind of a kind of adjusting device that is used to regulate the tail stock height, belongs to field of mechanical technique.
Background technology
Because tail stock moves on the guide rail of being everlasting, and adds use over a long time, causes the surface wear amount that is slidingly connected of slide of tail stock bottom and bed ways bigger.For improving the wearability of lathe guide pass, the lathe guide rail has been carried out heat-treatment quenching, improved guide pass hardness, so more accelerated the wearing and tearing of slide of tail stock bottom, caused tailstock axial line and headstock spindle axial line overproof to the equal altitudes of bed ways.Not only have a strong impact on the part to be processed precision when equal altitudes is overproof, the service life of simultaneously also having reduced cutter, during as drill centers, centre drill problem such as fracture easily.When generally investigating, equipment precision finds that tail stock sleeve axle center is all on the low side than headstock spindle axle center, past generally takes in the tailstock bottom surface with the method for binding agent bonding pad, raise tailstock center height, but when taking a lot of work so very much, and, after using a stage, still can reappear the high problem that reduces in tailstock center, simultaneously not attractive in appearance yet.
The utility model content
Technical problem to be solved in the utility model provides a kind of a kind of adjusting device of regulating the lathe height.
For solving the problems of the technologies described above, the utility model provides a kind of tail stock arrangement for adjusting height, comprise the tail stock body, in tailstock body, be provided with sleeve, in described sleeve, screw mandrel is set, it is characterized in that: adjacent with screw mandrel in described sleeve an eccentric bushing is set simultaneously, the outer surface of eccentric bushing is cylindrical, and inner surface is taper, and depart from mutually with the axle center of taper in described cylindrical axle center, cone is arranged in the eccentric bushing, and described eccentric bushing fixes by screw and location taper pin and sleeve.
Aforesaid tail stock arrangement for adjusting height is characterized in that: the distance of the cylindrical axle center of described eccentric bushing and the axle center skew of taper is 0.5-0.8mm.
The beneficial effect that the utility model reached:
Tail stock arrangement for adjusting height of the present utility model by the setting of eccentric bushing, can be regulated the turned position of eccentric bushing dynamically, thereby the height of sleeve is changed, and is simple in structure, easy to adjust, and the precision height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, a kind of tail stock arrangement for adjusting height of the present utility model, comprise tail stock body 3, in tailstock body 3, be provided with sleeve 2, in described sleeve 2, screw mandrel 1 is set, it is characterized in that: adjacent with screw mandrel 1 in described sleeve 2 eccentric bushing 5 is set simultaneously, the outer surface of eccentric bushing 5 is cylindrical, inner surface is taper, depart from mutually with the axle center of taper in described cylindrical axle center, cone 4 is arranged in the eccentric bushing 5, and described eccentric bushing 5 fixes with sleeve 2 by screw 6 and location taper pin 7.The distance of the cylindrical axle center of described eccentric bushing 5 and the axle center skew of taper is 0.5-0.8mm.
The operating process that tail stock arrangement for adjusting height of the present utility model is regulated is:
1) when barrel of tail stock taper hole center is more on the low side than headstock spindle taper hole center, loosens trip bolt 6, extract taper pin 7, dial as required and change eccentric bushing 5;
2) localization method of eccentric bushing 5 is: by the contour method of check, install check rod, fix dial gauge, and make its gauge head in vertical plane, touch check rod to move slide carriage and on the two limit positions of check rod, check, adjust the eccentric position of eccentric bushing 5 simultaneously according to the headstock spindle centre-height, make it go to contour precision prescribed;
3) utilize the original device of tailstock itself adjust centering barrel of tail stock axial line in horizontal plane to the depth of parallelism of spindle axis line, prepare screw 6 holes and the location taper pin 7 of tightening eccentric bushing 5 then again, and eccentric bushing 5 is fixing.
Tail stock arrangement for adjusting height of the present utility model not only is applicable to the height adjusting of tail stock, and the height that also can be suitable for other machine and furniture etc. is regulated.
Above embodiment limits the utility model never in any form, and all belong to protection domain of the present utility model to the equivalent transformation that above embodiment makes.
