Abstract
The utility model relates to a gapless linear lead rail, comprising a lead rail soleplate, a lead rail flexible piece, a lead rail, a lead rail cover board. The gapless linear lead rail is characterized in that the lead rail flexible piece is imbedded on the lead rail and the lead rail cover board; elastic fixtures are arranged in the gaps between the lead rail flexible piece and the lead rail, and between the lead rail flexible piece and the lead rail cover board. Three groups of elastic fixtures are arranged on the lead rail flexible piece, including a horizontal elastic fixture, a vertically upward elastic fixture and a vertically downward elastic fixture. Each elastic fixture includes a through hole and a steel ball on the lead rail flexible piece, a pressure ball cover, a spring, and a pressure adjusting nut. The steel ball in the through hole is arranged facing the lead rail, and the pressure ball cover, the spring and the pressure adjusting nut are sequentially arranged behind the steel ball. The gapless linear lead rail is capable of realizing gapless movement.
Description
Technical field
The utility model relates to a kind of line slideway, particularly a kind of gapless linear guide rail.
Background technology
In the multiaxis precision machine tool, use line slideway at present in a large number, the a few thing platform is installed on the line slideway, by screw mandrel workbench is done accurate running fix by stepper motor, utilize cutter that the workpiece on the workbench is carried out metal cutting processing then, the hyundai electronics development of numerical control (NC) technology, can realize very accurate numerical digit control, but the structure of present line slideway is to be with a guide rail to live clever on sliver, guide rail spirit alive is driven before and after sliver by screw mandrel and slides, guide rail spirit alive connects workbench again, and because the restriction of the precision of machining, sliver and guide rail are lived and are had the gap between the spirit, when sliding, guide rail spirit alive exists play up and down before and after sliver, affect the positioning accuracy of precision machine tool, the gap of therefore how to eliminate line slideway is one of key that improves whole precision machine tool machining accuracy.
Summary of the invention
The purpose of this utility model is the problem that there is the gap affects machining accuracy in the line slideway of precision machine tool in the solution prior art, and a kind of gapless linear guide rail is provided.The utility model designs a kind of gapless linear guide rail, comprise guide rail base plate, guide rail spirit alive, guide rail, guide rail cover plate, it is characterized in that: guide rail spirit alive is nested on guide rail and the guide rail cover plate, at the gap location flexible clamping device of guide rail spirit alive with guide rail and guide rail cover plate.Elastic clamp device on guide rail is lived spirit has three groups, for horizontal direction, vertically upward, vertically downward.The through hole of a pair of left and right horizontal one group of elastic clamp device of the horizontal direction in the guide rail spirit alive is lived spirit by guide rail on and steel ball, pressure ball lid, spring, adjusting pressure nut are formed, steel ball in through hole is pressure ball lid, spring, adjusting pressure nut behind steel ball with respect to guide rail according to this; Form by a pair of through hole that makes progress and steel ball, pressure ball lid, spring, adjusting pressure nut at live one group of elastic clamp device vertically upward of spirit of guide rail, steel ball in through hole is pressure ball lid, spring, adjusting pressure nut behind steel ball with respect to the bottom surface of guide rail cover plate according to this; Form by a pair of downward through hole and steel ball, pressure ball lid, spring, adjusting pressure nut at live one group of elastic clamp device vertically downward of spirit of guide rail, steel ball in through hole is pressure ball lid, spring, adjusting pressure nut behind steel ball with respect to above the guide rail base plate according to this.Every group of elastic clamp device can have more than two.The utility model has the advantages that the no gap that can realize line slideway moves.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
The specific embodiment
Comprise guide rail base plate 1, guide rail spirit 2 alive, guide rail 3, guide rail cover plate 4 among the figure, it is characterized in that: guide rail spirit 2 alive is nested on guide rail 3 and the guide rail cover plate 4, at the gap location flexible clamping device of guide rail alive clever 2 with guide rail 3 and guide rail cover plate 4.Elastic clamp device on guide rail is lived spirit 2 has three groups, for horizontal direction, vertically upward, vertically downward.The through hole 5 of a pair of left and right horizontal one group of elastic clamp device of the horizontal direction in the guide rail spirit 2 alive is lived spirit 2 by guide rail on and steel ball 6, pressure ball lid 7, spring 8, adjusting pressure nut 9 are formed, steel ball 6 in through hole 5 is pressure ball lid 7, spring 8, adjusting pressure nut 9 according to this with respect to guide rail 3 behind steel ball 6; Guide rail live one group of elastic clamp device vertically upward of spirit 2 by a pair of through hole that makes progress 10 and steel ball 11, pressure ball lid 12, spring 13, regulate pressure nut 14 and form, steel ball 11 in through hole 10 is pressure ball lid 12, spring 13, adjusting pressure nut 14 according to this with respect to the bottom surface of guide rail cover plate 4 behind steel ball 11; Guide rail live one group of elastic clamp device vertically downward of spirit 2 by a pair of downward through hole 15 and steel ball 16, pressure ball lid 17, spring 18, regulate pressure nut 19 and form, steel ball 16 in through hole 15 is pressure ball lid 17, spring 18, adjusting pressure nut 19 according to this with respect to above the guide rail base plate 1 behind steel ball 16.Every group of elastic clamp device can have more than two.
Owing on guide rail is lived spirit 2, a left side is arranged, right, on, following three groups of steel balls 6,11,16, pressure ball lid 7,12,17, spring 8,13,18, regulate pressure nut 9,14,19, in assembling, can regulate pressure nut 9,14,19 degree of tightness, can be with steel ball 6,11,16 are pressed in guide rail 3 respectively, the bottom surface of guide rail cover plate 4, above the guide rail base plate 1, and can guarantee steel ball 6,11,16 rolling, make guide rail spirit 2 alive be pressed on guide rail base plate 1 and guide rail 3 and the guide rail cover plate 4, eliminated between them because of gapped rocking of causing, and because steel ball 6,11,16 can roll with contact-making surface, therefore can not influence guide rail live spirit 2 move forward and backward smooth and easy, can realize gapless line slideway technology.
