Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machining, in particular to a leveling mechanism. Background Art
[0002] When components used in aviation are processed by machine tools or machining centers, in order to ensure the processing accuracy of non-through structures such as grooves, the processed plates are often leveled by means of pads. This leveling operation is complicated and the difficulty of leveling is undoubtedly increased as the weight and size of the plate increase. Utility Model Content
[0003] The utility model provides a leveling mechanism to solve the above-mentioned deficiencies in the prior art and the problem that it is inconvenient to perform leveling during machining of components, and has strong practicability.
[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:
[0005] A leveling mechanism comprises a base plate, which has a rectangular structure and is provided with four pairs of movable holes, wherein the length directions of two pairs of movable holes are parallel to the length direction of the base plate, and the length directions of the other two pairs of movable holes are parallel to the width direction of the base plate. A ball seat is installed on the base plate, a ball is arranged in the ball seat, a rod is arranged on the ball, the rod extends from the upper end of the ball seat, an upper plate is installed on the upper end of the rod, and the arrangement of the ball seat and the ball enables the upper plate to rotate and deflect around the center of the ball, thereby facilitating the leveling operation of the processed plate.
[0006] The lower wall of the base plate is provided with a pair of movable plates which are arranged perpendicularly to each other, and the movable plates are distributed up and down. Multiple groups of screws are provided at both ends of the movable plates, and the screws are passed through the movable holes. A lower top block is provided at the upper end of each group of screws, and multiple lower extension seats are installed on the upper plate. The lower end of the lower extension seat is an inclined surface, and the upper end of the lower top block has an inclined wall, and the inclination angle of the inclined wall is consistent with that of the inclined surface. When the lower top block moves, the interaction between the inclined wall and the inclined surface can achieve the leveling operation of the upper plate, and after adjustment, the stability of the support can be improved due to the contact between the inclined wall and the inclined surface.
[0007] Furthermore, an arc groove is provided at the upper end of the lower top block, and the lower end of the lower extension seat is in a U-shaped structure, and the lower end of the lower extension seat is located in the arc groove. This design method avoids the support of one pair of lower top blocks and the lower extension seat from affecting the leveling operation in another direction.
[0008] Furthermore, a moving seat is installed at one end of the movable plate, a moving rod is installed on the moving seat, a threaded head is provided at the outer end of the moving rod, an adjusting thread sleeve is provided outside the threaded head, a rotating seat is provided at the inner end of the adjusting thread sleeve, and the rotating seat is installed on the base plate. Through the adjusting thread sleeve, when it rotates, it can drive a pair of lower top blocks arranged in the axial direction to move, and the leveling operation can be performed through the movement of the lower top blocks.
[0009] Furthermore, a rotating sleeve is provided at the outer end of the adjusting thread sleeve to facilitate the operator to rotate the adjusting thread sleeve.
[0010] The advantages of the above technical solution are:
[0011] The utility model facilitates the leveling operation of the processing plate and reduces the difficulty of leveling. BRIEF DESCRIPTION OF THE DRAWINGS

Multiple groups of screws 41 are provided at both ends of the movable plates 42, and the screws 41 are inserted into the moving holes 10. The upper end of each group of screws 41 is provided with a lower top block 40. Multiple lower extension seats 4 are installed on the upper plate 3. The lower end of the lower extension seat 4 is an inclined surface, and the upper end of the lower top block 40 has an inclined wall, and the inclined wall and the inclined surface have the same inclination angle. An arc groove is opened at the upper end of the lower top block 40, and the lower end of the lower extension seat 4 is a U-shaped structure, and the lower end of the lower extension seat 4 is located in the arc groove.
