Abstract
The utility model discloses a precise floating connector device which comprises a connector body. A floating connector is connected at an inner hole of the connector body, and a thrust bearing which can be adjusted in a radial direction is arranged between the inner hole of the connector body and the floating connector. According to the precision floating connector device, a thrust bearing structure is arranged between the connector body (4) and the floating connector (1) in a sliding friction mode. Abrasion is greatly reduced, precision is improved, service life is prolonged, and radial floating of the floating connector (1) relative to the connector (4) is flexible and reliable.
Description
Technical field
The utility model relates to a kind of connection set, particularly a kind of accurate floating junction device that is used on three bore hole lathes of highi degree of accuracy.
Background technique
Be connected with fittings body on three bore hole machine tool chief axis of existing highi degree of accuracy, fittings body rotates with main shaft, be connected to floating junction with fittings body, boring bar on the bore hole lathe is installed on the floating junction, the radial floating structure of floating junction is traditional crosshead shoe form, and floating junction and the radial floating between the fittings body that boring bar is installed are the slip form, and wherein slide block weares and teares easily, the axially locating precision is relatively poor, influences the machining accuracy of lathe.
Summary of the invention
The purpose of this utility model provides a kind of accurate floating junction device little, that precision is high that weares and teares, and overcomes the deficiencies in the prior art.
Accurate floating junction device of the present utility model comprises fittings body, is connected with floating junction at the endoporus place of fittings body, is provided with the thrust bearing that can radially adjust between the endoporus of fittings body and the floating junction.
Accurate floating junction device of the present utility model, floating junction (1) outer circumference in the wherein said endoporus that is positioned at fittings body (4) is provided with boss, and described thrust bearing has two groups and be located at the both sides of this boss respectively.
Accurate floating junction device of the present utility model, two inner thrust rings on wherein said two groups of thrust bearings lay respectively at the both sides of boss, the inner thrust ring on right side and be enclosed between the right outer thrust ring on the floating junction, the inner thrust ring in left side and be enclosed between the left outer thrust ring on the floating junction and all be arranged with ball, ball is arranged in the retainer, be bolted to connection the flange plate of axial limiting in the termination of fittings body, flange plate leans outside a left side on the thrust ring, and it is circular that described inner thrust ring, the outer thrust ring in a left side and right outer thrust ring are flat board.
Accurate floating junction device of the present utility model owing to be the sliding type friction between fittings body and the floating junction, has reduced wearing and tearing greatly, has improved precision, has prolonged working life, and floating junction is with respect to the radial floating flexibility and reliability between the fittings body.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: the 4th, with the fittings body that three bore hole machine tool chief axis of highi degree of accuracy are connected, this fittings body 4 joins by construction bolt 17 and main shaft.Endoporus place at fittings body 4 is connected with floating junction 1, be provided with the connecting key 9 of two symmetries in the termination of floating junction 1 and the fittings body 4 between the hole end surface, connecting key 9 is positioned at the keyway of floating junction 1 termination and fittings body 4 endoporus ends, and floating junction 1 end face is processed with spring eye and is provided with spring 16 and leans connecting key 9.Between floating junction 1 and fittings body 4, leave the flying height 18 of 0.15mm.Floating junction 1 can be with respect to radial floating between the fittings body 4 in the rotation process,
Be provided with the thrust bearing that radially to adjust between fittings body 4 endoporus and the floating junction 1, the concrete structure of this thrust bearing is as follows: floating junction 1 outer circumference that is positioned in the endoporus of fittings body 4 is provided with boss, and thrust bearing has two groups and be located at the both sides of this boss respectively.Two inner thrust rings 7 on two groups of thrust bearings lay respectively at the both sides of boss, the inner thrust ring 7 on right side and be enclosed between the right outer thrust ring 8 on the floating junction 1, the inner thrust ring 7 in left side and be enclosed between the left outer thrust ring 5 on the floating junction 1 and all be arranged with ball 14, ball 14 is arranged in the retainer 6.Be fixedly connected with the flange plate 3 of axial limiting by fixing bolt 12 in the termination of fittings body 4, flange plate 3 lean outside a left side on the thrust ring 5 and and floating junction 1 between be provided with seal ring 13.Inner thrust ring 7, the outer thrust ring 5 in a left side and right outer thrust ring 8 are dull and stereotyped circular.15 is boring bar, has position-limited nail 2 to carry out axial limiting between boring bar 15 and the floating junction 1, the limited screw 10 that between floating junction 1 and boring bar 15, also is threaded and is obliquely installed, and fastening by fastening screw trip bolt 11.
Accurate floating junction device of the present utility model owing to be the sliding type friction between fittings body 4 and the floating junction 1, has reduced wearing and tearing greatly, has improved precision, has prolonged working life, and floating junction 1 is with respect to the radial floating flexibility and reliability between the fittings body 4.
