Embodiment 1

[0034]Embodimentsfigure 1 As shown, a flat bed body with a self-compensating rail gap adjustment structure includes a guide rail 1 and a slider 2 that is slidably coupled to the guide rail 1, and the specific connection method of the guide rail 1 and the slider 2 is: the guide rail 1 is in parallel T-T type The two sidewalls are inclined outwardly, and the bottom end of the slider 2 has a groove, and the inner wall of the groove is adapted to both side walls of the guide rail 1.

[0035]Such asfigure 1 As shown, there is a gap between the side wall of the guide rail 1 and the inner wall of the slider 2, the top surface of the guide rail 1 and the bottom end surface of the bottom end surface of the slider 2 recess, and there is a conditioning mechanism in the gap, and the adjustment mechanism includes a frame 3, the rotary axis 4. The cam 5 and the driver are connected to the bottom end surface of the slider 2 through the screw, and the rotation shaft 4 is rotated to the bottom end of t...

Embodiment 2

[0045]Example 2 Basicfigure 2As shown, the difference between the second embodiment and the embodiment is that the drive member is a plastic rod 10 of the POM material, and the outer wall of the plastic rod 10 is bonded to the canvas 11, and since the plastic rod 10 of the POM is very wear and is not easily deformed. A certain support can be provided to the slider 2 degree movement; the canvas 11 has a larger coefficient of friction and strong wear resistance, and when the slider 2 is relatively moved, the canvas 11 can quickly turn the shaft 4 to the machine tool. The machining is more accurate.

Abstract

The invention relates to the technical field of mechanical processing, in particular to a flat bed with a self-compensating guide rail gap adjustment structure, including a guide rail and a slide block slidably connected to the guide rail. There is a gap between the guide rail and the slide block. There is an adjustment mechanism in the gap; the adjustment mechanism includes a stand, a rotating shaft, a cam and a driving part. The stand is fixedly connected to the end surface of the bottom of the slider, and the rotating shaft is connected to the stand in rotation. The number of rotating shafts is at least two, and the rotating shafts are distributed in the The two sides of the guide rail; the driving part is fixedly connected to the shaft, the side wall of the driving part is against the side wall of the guide rail, and there is a gap between the side wall of the other side and the inner wall of the slider; the cam is fixedly connected to the shaft, and the far end of the cam can be against the side wall of the guide rail. In the present invention, when the rotating shaft rotates to drive the cam to rotate, the far end of the cam contacts the inner wall of the guide rail, and finally the gap between the slider and the guide rail is fixed, which solves the problem in the prior art that the machining accuracy of the machine tool is reduced due to the wear of the guide rail and the slider question.

Description

Technical field[0001]The present invention relates to the field of machining, and in particular, to a flat bed body with a self-compensated rail gap adjustment structure.Background technique[0002]The machine tool is constantly developing in the machining industry. Modern machinery manufacturing technology is moving towards high efficiency, high quality, high precision, high integration and high intelligence direction. In order to ensure the accuracy of machine tool processing machinery parts, people continue to improve the structure of machine tools and their The components of the components.[0003]The machine error refers to the initial position error and the motion error caused by other factors such as manufacturing, installation, motion control in the machine space. When the tool, bed, and thermal deformation is integrated, when the slide rails on the machine are continuously highly intensified or After the use time increases, the slider is in a gap between the slider, and the mac...
