Abstract
The invention relates to a lead screw bracket, which is characterized by comprising a seat sleeve, a bottom support at the bottom of the seat sleeve and a ball spline mounted in the seat sleeve, wherein a compression spring is mounted at the bottom of a spline shaft of the ball spline; a lead screw support rolling wheel is mounted at the upper part of the spline shaft of the ball spline through connecting of a connecting plate and a rolling wheel bracket; and a cam driven bearing is mounted on the rolling wheel bracket and can contact with a press plate mounted on a component driven by a lead screw. According to the invention, the lead screw is prevented from shaking when rotating; and the allowable rotating speed of the lead screw is improved, so that the running speed of an executing mechanism is improved. The lead screw bracket is mounted at the middle of the lead screw, so that the running of a moving component is not influenced. Therefore, the lead screw bracket can be used as an auxiliary support mechanism of the lead screw, and is especially suitable for the lead screw of a large-stroke machine tool.
Description
Technical field
The present invention relates to a kind of machine tool functional component, particularly a kind of being installed on the bed piece provides the screw bracket of supplemental support for leading screw.
Background technology
Machine tool motion component generally adopts the screw pair of leading screw rotation to drive, leading screw is two end supports, nut moves between two strong points, distance between the dangerous rotating speed of leading screw (maximum speed that namely allows) and two strong points is inversely proportional to, the larger dangerous rotating speed of strong point distance is lower, will cause the speed of service of executing agency slow for the lathe of large stroke.If can increase the leading screw supplemental support that does not affect the moving component walking at the leading screw middle part will address this problem.
Summary of the invention
The object of the invention is to overcome above-mentioned defective of the prior art, provide a kind of for leading screw provides supplemental support, tremble when preventing the leading screw rotation, improve the holder for screw rod of leading screw allowable rotating speed.
The objective of the invention is to realize by following technical proposals:
A kind of screw bracket is characterized in that comprising the collet of cover for seat, cover for seat bottom and the ball spline of the interior installation of cover for seat, and the splined shaft bottom of described ball spline is equipped with Compress Spring, and top is connected and installed with the leading screw support roller by connecting plate and rolling wheel support; On the above-mentioned rollers support cam follower shaft is installed and holds, this cam follower shaft hold can be installed in the parts that driven by leading screw on pressing plate contact.
Between described connecting plate and the rolling wheel support adjusting pad is installed.
The bottom of described splined shaft is equipped with limiting plate.
The two ends, bottom surface of described pressing plate are to move angled inclined-plane, plane with executing agency.
Screw bracket of the present invention has following characteristics: 1. support roller etc. is installed on the ball spline, can not rotate during motion, guaranteed that the support roller axis of adjusting remains and the lead screw shaft line parallel, be between the kinematic pair simultaneously rolling friction to have guaranteed the smooth and reliable of motion; 2. the Compress Spring through checking has guaranteed that the pair of rollers leading screw has suitable support force; 3. between rolling wheel support and connecting plate, adjusting pad is set, has guaranteed the degree of accuracy of Support Position; 4. in the splined shaft bottom limiting plate is set, guarantees that the support roller Support Position accurately, unanimously.
In sum, screw bracket of the present invention trembles in the time of can preventing the leading screw rotation, improves the leading screw allowable rotating speed, thereby has improved the speed of service of executing agency.The present invention is installed in the leading screw middle part, does not affect the moving component walking, can be used as the leading screw auxiliary support mechanism, and the leading screw that especially is fit to large stroke lathe supports auxiliary support mechanism.
Description of drawings
Accompanying drawing 1 is the structural representation of facing of screw bracket of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is described.
As attached illustrated in figures 1 and 2, screw bracket of the present invention is installed in the leading screw middle part, and its structure comprises cover for seat 2, and cover for seat 2 bottoms are equipped with the collet 1 for sealing cover for seat 2.Ball spline 5 is installed in cover for seat 2, and the basic structure of described ball spline 5 comprises splined shaft 5-1, spline housing 5-3 and the ball 5-2 that installs between the two.Described spline housing 5-3 is fixedly mounted on the cover for seat 2.Splined shaft 5-1 bottom is equipped with Compress Spring 4 and limiting plate 3.The top of splined shaft 5-1 is connected and installed with support roller 10 by connecting plate 6 and rolling wheel support 8, and support roller 10 has two, is symmetrically distributed in the leading screw both sides.Between connecting plate and the rolling wheel support 8 adjusting pad 7 is installed, is used for guaranteeing the accuracy of Support Position.Rolling wheel support 8 both sides are equipped with cam follower shaft and hold 9, this cam follower shaft hold 9 can be installed in the parts that driven by leading screw on pressing plate 11 contact.Pressing plate 11 is 9 promotion support rollers 10 by cam follower shaft and associated components moves up and down.The present invention is installed in the position at corresponding leading screw middle part on the bed piece, the leading screw I is carried out supplemental support, when feed screw nut II drive machine tool motion component departs from the leading screw centre position, the parts such as spring 4 jack-up splined shaft 5-1, connecting plate 6, adjusting pad 7, rolling wheel support 8, support roller 10 make support roller 10 be in the position B that supports the leading screw I; When machine tool motion component walks to this device installation site, being installed in pressing plate 11 inclined-planes on the moving component holds 9 with cam follower shaft and contacts, promote support roller 10, rolling wheel support 8, adjusting pad 7, connecting plate 6, splined shaft 5-1 decline, support roller 10 is in break away from the position A of leading screw I, passes through the space thereby abdicate for feed screw nut II and machine tool motion component; Machine tool motion component promotes support roller 10 by rear spring 4 again and recovers position B.
