Description

Technical Field

[0001] The utility model relates to the technical field of guide rail leveling, in particular to a large-area embedded guide rail leveling mechanism. Background Art

[0002] A guide rail is a groove or ridge made of metal or other materials, which can bear, fix, guide a moving device or equipment and reduce its friction. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine components, special equipment, instruments, etc. The guide rail is also called a slide rail, a linear guide rail, a linear slide rail, and is used in occasions of linear reciprocating motion. It has a higher rated load than a linear bearing, and can also bear a certain torque, and can achieve high-precision linear motion under high load. The embedded guide rail is mainly used in equipment installation platforms.

[0003] Regarding the problems in the related art, no effective solution has been proposed yet.

[0004] 1. When the existing large-area embedded guide rail leveling mechanism is in use, the achieved effect is not very good. It is difficult to ensure the overall levelness of the guide rails when embedding multiple groups of guide rails in a large area. The levelness of the guide rail assembly directly affects the levelness, stability and service life of the platform. If the platform is unstable, after the equipment is installed, situations such as shaking and tilting may occur, which not only affects the normal operation of the equipment, but also has a serious impact on the accuracy and life of the equipment. For example, when installing high-precision measuring instruments, even a slight shake of the platform may cause deviations in the measurement results. If the levelness of the guide rail is not good, it will cause errors during the use of the platform, affecting the installation and measurement accuracy and quality of the workpiece. The vibration and shaking of the guide rail during the working process affect the stability of the platform. Summary of the Invention

[0005] Regarding the problems in the related art, the utility model proposes a large-area embedded guide rail leveling mechanism to overcome the above technical problems existing in the existing related art.

[0009] By adopting the above technical solution, the support rod in this solution can make a rotational movement inside the rotating groove, thereby driving the horizontal scale to make a rotational movement centered on the support rod, which can meet the measurement of two points of multiple groups of guide rails simultaneously.

[0010] A further improvement of the technical solution of the present utility model lies in that: plastic buckles are fixedly connected in a circumferential array at the inner bottom of the movable cavity, and the support rod is arranged at the central position between the plastic buckles.

[0011] By adopting the above technical solution, the plastic buckles in this solution are used to clamp and fix the support rod, thereby playing a stabilizing role for the horizontal scale.

[0013] A further improvement of the technical solution of the present utility model lies in that: slots are provided on both inner walls of the movable cavity, the slots penetrate through the outer wall of the sleeve block, connecting plates are fixedly connected to both ends of the sleeve block, and the connecting plates are slidably connected inside the slots.

[0014] By adopting the above technical solution, the connecting plates in this solution are placed outside the support rod through the slots, and the sleeve block can be driven to move downward by pressing the connecting plates, so that the sleeve block makes a sliding movement inside the movable cavity.

[0015] A further improvement of the technical solution of the present utility model lies in that: a second inclined surface is provided at the inner edge of the bottom of the sleeve block, and a first inclined surface is provided at the upper end of the plastic buckle.

[0016] By adopting the above technical solution, the first inclined surface and the second inclined surface are used for mutual friction. When the sleeve block is driven to slide downward by pressing the connecting plates, the first inclined surface and the second inclined surface will rub against each other, driving the plastic buckles to approach each other, thereby clamping and fixing the support rod, and further playing a stabilizing role for the horizontal scale, facilitating the user to observe and measure.

[0017] A further improvement of the technical solution of the present utility model lies in that: a return spring is fixedly connected to the bottom of the connecting plate, and the bottom of the return spring is fixedly connected to the bottom of the slot.

[0018] With the above technical solution, the reset spring in the solution can drive the connecting plate to drive the sleeve block to perform a reset movement, so that the sleeve block returns to its original position.

[0019] The beneficial effects of the present utility model are as follows:
