[0002] A workbench is a machine tool accessory that can mount workpieces and also move them.

[0003] When the workbench measures or processes the workpiece, it is often necessary to adjust the measured object so that the measured object and the measurement or processing reference (such as the main axis of the equipment) coincide as much as possible to ensure the accuracy of the measurement or processing. The traditional workbench has a single function and is not convenient for adjusting the axis and level of the workbench as required, which has limitations in the processing of different equipment. Utility Model Content

[0004] The utility model aims to provide a large-load leveling and centering workbench, wherein the workbench surface and the mounting base are supported by a middle plate supporting steel ball and an inclined supporting steel ball respectively, so that the displacement generated by the adjustment moves on the rolling body, which is rolling friction, and thus the friction force is small; the steel ball itself has high rigidity and can carry heavy workpieces; the threaded structure is adopted in the adjusting screw to make the adjustment more delicate and obtain a higher adjustment accuracy.

[0005] To achieve the above-mentioned purpose, a large-load leveling and centering workbench is provided, comprising: a mounting base, a base extension shaft is fixedly connected to the middle of the mounting base, a top end of the base extension shaft is attached to a work surface, a horizontal connecting rod structure is slidably matched on one side of the bottom end of the work surface, a middle-layer structure disk is fixedly connected to the bottom end of the horizontal connecting rod structure, a plurality of middle-layer support steel balls are rollingly matched between the middle-layer structure disk and the mounting base, and one end of the horizontal connecting rod structure is in contact with a first horizontal adjustment screw;

[0006] The other side of the bottom end of the work surface is slidably matched with a tilting connecting rod mechanism, and one side of the tilting connecting rod mechanism is provided with a tilting supporting steel ball, and the tilting supporting steel ball is respectively in contact with the work surface and the middle structure disk.

[0007] According to the large-load leveling and centering workbench, the bottom end of the upper surface of the mounting base is fixedly connected to a workbench side plate frame, and the upper inner portion of the workbench side plate frame is respectively threadedly engaged with a first horizontal adjustment screw and a first tilt adjustment screw.

[0024] Reference Figure 1-2The utility model embodiment is a large-load leveling and centering workbench, which includes: a mounting base 1, a base extension shaft 3 is fixedly connected to the middle of the mounting base 1, and the base extension shaft 3 plays a supporting role. The top of the base extension shaft 3 is attached to a work table 12, and a horizontal connecting rod structure 13 is slidably matched on one side of the bottom end of the work table 12. The horizontal connecting rod structure 13 can keep the middle structure disk 11 in a stable horizontal position. The bottom end of the horizontal connecting rod structure 13 is fixedly connected to the middle structure disk 11, and a number of middle disk supporting steel balls 2 are rollingly matched between the middle structure disk 11 and the mounting base 1. The surface is provided with a plurality of middle plate supporting steel balls 2, so that the middle structure plate 11 can move horizontally in any direction on the mounting base 1, one end of the horizontal connecting rod structure 13 is in contact with the first horizontal adjustment screw 14, and the bottom end of the upper surface of the mounting base 1 is fixedly connected with a workbench side plate frame 17, and the upper part of the inner part of the workbench side plate frame 17 is respectively threadedly matched with the first horizontal adjustment screw 14 and the first tilt adjustment screw 5, and the four sides of the workbench side plate frame 17 are respectively provided with the first tilt adjustment screw 5, the first horizontal adjustment screw 14, the second tilt adjustment screw 15 and the second horizontal adjustment screw 16. Through the adjustment of the four sides, it can be applied to different scenes and reduce the limitations of use;

[0025] The other side of the bottom end of the work table 12 is slidably matched with a tilting connecting rod mechanism 7, and a tilting supporting steel ball 9 is arranged on one side of the tilting connecting rod mechanism 7. Three tilting supporting steel balls 9 are arranged on the upper surface of the middle structure disk 11, forming a three-point support that can fully contact the conical surface at the bottom of the work table 12, and can rotate around the conical surface at the bottom of the work table 12 and the three steel balls. The tilting supporting steel balls 9 are respectively in contact with the work table 12 and the middle structure disk 11. The middle part of the middle structure disk 11 is open, and the middle part of the base extension shaft 3 and the horizontal connecting rod structure 13 are fixed. A horizontal return spring 10 is fixedly connected, and the position of the middle-layer structure disk 11 can be moved by the horizontal return spring 10, so that the elastic support can be played elastically and a return effect can be provided. A tilting return spring 4 is arranged between the other side of the bottom end of the work table 12 and the middle-layer structure disk 11, and the tilting return spring 4 can provide spring tension when the work table is tilted to improve the return effect. A tilting support point 8 is arranged on the other side of the inside of the work table 12, and a rotating rod is rotatably connected between the tilting support point 8 and the tilting connecting rod mechanism 7, and a middle-layer protective cover 6 is arranged between the work table 12 and the mounting base 1.

[0026] Working principle: The middle-layer structure disk 11 is a mechanism serving for adjusting the entire workbench. A number of middle-layer support steel balls 2 are arranged on the bottom surface of the middle-layer structure disk 11 and the upper surface of the mounting base 1, so that the middle-layer structure disk 11 can move horizontally in any direction on the mounting base 1; the first horizontal adjustment screw 14 and the second horizontal adjustment screw 16 of the angle of the worktable surface 12 can force the middle-layer structure disk 11 to move away from or approach the base extension axis 3 of the mounting base 1; the first horizontal adjustment screw 14 and the second horizontal adjustment screw 16 in the angle direction are adjusted at the same time, so that the middle-layer structure disk 11 can move arbitrarily within a certain range on the upper surface of the mounting base, thereby completing the horizontal position adjustment (commonly known as centering, i.e. adjusting the concentricity). The upper structure is a work surface 12, which is used for installation and connection with the workpiece to be measured or processed. The upper surface of the middle structure disk 11 is provided with three tilting support steel balls 9, which form a three-point support that can fully contact the conical surface at the bottom of the work surface 12, and can rotate around the conical surface at the bottom of the work surface 12 and the three steel balls. The first tilt adjustment screw 5 and the second tilt adjustment screw 15 at the other two angles on the middle structure disk 11 can push the middle structure disk 11 through the rotation of the first tilt adjustment screw 5 or the second tilt adjustment screw 15, and the work surface 12 can be lifted up through the resistance of the conical surface to the tilt support steel balls 9, thereby completing the tilt adjustment function and completing the upper position adjustment of the work surface 12 in the tilt direction (commonly known as leveling, that is, adjusting the parallelism of the workpiece and the reference). The rotation of the four adjustment screws can obtain more precise micro-adjustments to ensure the adjustment accuracy.
