Abstract

The invention relates to a center frame for CNC lathe additional support, comprising a vertically arranged ring support and three supporting arms that are arranged on and symmetrically distributed onthe ring support; wherein the supporting arm is composed of a guide holder, a guiding shaft, an adjusting screw rod and a trolley, wherein the guide holder is fixed on the ring support, the cavity thereof is provided with the guiding shaft, the adjusting screw rod is connected with the guiding shaft by penetrating the bottom of the guide holder, the trolley is fixed at the top of the guiding shaft, the guiding shaft is opened with a ring-shaped groove, and the ring-shaped groove is internally provided with a ball, so that the slide fit between the guiding shaft and a guiding sleeve is changedinto rolling fit of the ball and the guide holder, thus greatly reducing adjusting difficulty.

Description

A kind of numerically controlled lathe supplemental support centre frame
Technical field
The present invention relates to a kind of numerically controlled lathe supplemental support centre frame, comprise vertically disposed ring support, and be installed in three support arms that are symmetrical distribution on the ring support.
Background technology
When carrying out the processing of big profile shaft, the workbench of numerically controlled lathe can't be fixed whole axis body, needs to use centre frame come supplemental support.It is by vertically disposed ring support, and be installed in three support arms that are symmetrical distribution on the ring support and form, support arm mainly comprises the guide holder that is fixed on the ring support, is located at the axis of guide in the guide holder, and the roller that is located at the large-scale axis body of axis of guide apical support.The shaft diameter that supports when centre frame need adapt to by the extension elongation of adjusting the axis of guide, and traditional centre frame support arm adopts guide holder and axis of guide gap to be slidingly matched not simultaneously, inconvenience during adjustment, and the strength of needs is bigger, and roller is fragile.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of conveniently adjusted numerically controlled lathe supplemental support centre frame.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of numerically controlled lathe supplemental support centre frame, comprise vertically disposed ring support, and be installed in three support arms that are symmetrical distribution on the ring support, described support arm is by guide holder, the axis of guide, regulating screw mandrel and roller forms, described guide holder is fixed on the ring support, be provided with the axis of guide in its cavity, the adjusting screw mandrel passes the guide holder bottom and is connected with the axis of guide, roller is fixed on the top of the axis of guide, its innovative point is: have several equally distributed Baltimore grooves on the described axis of guide, be provided with ball in the described Baltimore groove, and described roller is a taper roll bearing.
The invention has the advantages that: by on the axis of guide, opening Baltimore groove, ball is set in the groove, being slidingly matched between the axis of guide that makes and the fairlead becomes ball and cooperates with the rolling of guide holder, greatly reduce the adjusting difficulty, taper roll bearing can bear big radial load and axial load, and is not fragile.
Description of drawings
Fig. 1 is the structural representation of numerically controlled lathe supplemental support of the present invention with centre frame.
Fig. 2 is the structural representation of support arm of the present invention.
The specific embodiment
As shown in the figure, comprise ring support 1, support arm 2, support arm 2 comprises guide holder 3, the axis of guide 4, regulates screw mandrel 5, roller 6, Baltimore groove 7, ball 8.
Above-mentioned ring support 1 is provided with three support arms 2 that are symmetrical distribution, the guide holder 3 of this support arm 2 is fixed on the ring support 1, be provided with the axis of guide 4 in the cavity, the axis body outer surface of this axis of guide 4 has some equally distributed Baltimore grooves 7, plurality of balls 6 is housed in the groove, and the bottom of the axis of guide 4 has screwed hole, and the end is fixed with bearing pin, cover is useful on the roller 6 that props up large-scale axis body on the bearing pin, and this roller 6 is a taper roll bearing.Regulate screw mandrel 5 and pass from the bottom of guide holder 3 and being connected of the axis of guide 4, be being slidingly matched of screw thread and nut between described adjusting screw mandrel 5 and guide holder 3 and the axis of guide 4.
When large-scale axis body was processed on numerically controlled lathe, the other end passed the ring support 1 of centre frame, rotated and regulated screw mandrel 5, made pulley 6 reaches of the axis of guide 4 front ends to prop up or support axis body from three directions.During adjusting, the rolling of the relative displacement of the axis of guide 4 and guide holder 3 by ball 6 cooperates and realizes, regulates easy and conveniently, and roller 6 is a taper roll bearing, can bear bigger radial load and axial load, and is not fragile.

Claims (1)

1. numerically controlled lathe supplemental support centre frame, comprise vertically disposed ring support, and be installed in three support arms that are symmetrical distribution on the ring support, described support arm is by guide holder, the axis of guide, regulating screw mandrel and roller forms, described guide holder is fixed on the ring support, be provided with the axis of guide in its cavity, the adjusting screw mandrel passes the guide holder bottom and is connected with the axis of guide, roller is fixed on the top of the axis of guide, it is characterized in that: have several equally distributed Baltimore grooves on the described axis of guide, be provided with ball in the described Baltimore groove, and described roller is a taper roll bearing.
