Embodiment 1

[0034] Embodiment one is basically as figure 1 As shown, the flat bed with self-compensating guide rail gap adjustment structure includes guide rail 1 and slider 2 slidingly connected to guide rail 1. The specific connection method between guide rail 1 and slider 2 is: guide rail 1 is in an inverted T shape as a whole , its two side walls are all inclined outwards, the bottom end of the slider 2 has a groove, and the inner wall of the groove is adapted to the two side walls of the guide rail 1.

[0035] Such as figure 1As 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 groove of the slider 2, and an adjustment mechanism is provided in the gap, and the adjustment mechanism includes a stand 3 and a rotating shaft 4 , the cam 5 and the driver, the stand 3 is fixedly connected to the bottom end surface of the groove of the slider 2 by screws, the rotating shaf...

Embodiment 2

[0045] Embodiment two is basically as figure 2 As shown, the difference between Embodiment 2 and Embodiment 1 is that the driving part is a plastic rod 10 made of POM, and the outer wall of the plastic rod 10 is bonded with a canvas 11. Since the plastic rod 10 made of POM is very wear-resistant and not easily deformed, It can provide a certain support for the 2-degree movement of the slider; the canvas 11 has a large friction coefficient and strong wear resistance. When the slider 2 and the guide rail 1 move relative to each other, the canvas 11 can quickly rotate the shaft 4 and make the machine tool The processing is more precise.

Abstract

The invention relates to the technical field of mechanical processing, in particular to a flat lathe bed with a self-compensated guiding rail gap adjustment structure. The flat lathe bed comprises a guiding rail and a sliding block slidably connected to the guiding rail, a gap is kept between the guiding rail and the sliding block, an adjustment mechanism is arranged in the gap between the guidingrail and the sliding block and comprises a standing frame, at least two rotating shafts, cams and driving pieces, the standing frame is fixedly connected with the end face of the bottom of the sliding block, the at least two rotating shafts are rotatably connected to the standing frame, the rotating shafts are distributed on the two sides of the guiding rail respectively, the driving pieces are fixedly connected with the rotating shafts respectively, one side wall of each driving piece is propped against the side wall of the guiding rail, a gap is kept between the other side wall of each driving piece and the inner wall of the sliding block, the cam is fixedly connected with the rotating shafts, and the far end of each cam is capable of being propped against the side wall of the guiding rail. According to the flat lathe bed, when the cams are driven to rotate by using the rotation of the rotating shafts, the far ends of the cams make contact with the inner wall of the guiding rail, finally, the gap between the sliding block and the guiding rail is made to be fixed, and the problem that the processing accuracy of a machine tool is reduced due to the wear of the guiding rail and thesliding block in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a flat bed with a self-compensating guide rail gap adjustment structure. Background technique [0002] Machine tools continue to develop in the machining industry. Modern machinery manufacturing technology is developing in the direction of high efficiency, high quality, high precision, high integration and high intelligence. The component structure above. [0003] Machine tool error refers to the initial position error and motion error caused by inaccurate manufacturing, installation, motion control and other factors such as tool, bed and thermal deformation in the machine tool motion space. After the use time increases, there will be different gaps between the slider and the slide rail, and the machine tool will shake from side to side when sliding, which not only affects the guiding accuracy of the machine tool when it is working, but also due to the offset between the slide...
