Small precise leveling device

Abstract

The invention provides a small precise leveling device which comprises a supporting platform, wherein the supporting platform and a main adjusting screw are in threaded connection; the end part of the upper end of the main adjusting screw extends out of and leans against the upper surface of the supporting platform and is connected with a spherical hinge support; the lower end of the main adjusting screw extends out of the lower surface of the supporting platform and is in threaded connection with a big bevel gear; the big bevel gear and a small bevel gear are meshed; the side part of the small bevel gear is connected with a hand wheel by a driving shaft; the bottom of the big bevel gear is connected with a spring pre-tightening assembly; and a thread pair at the end part of the lower endof the main adjusting screw is connected with a main locking assembly. Through adoption of the small precise leveling device, a part can be quickly leveled under a heavy load working condition. The small precise leveling device is also suitable for leveling under an asymmetric load condition. The small precise leveling device has a simple and artful structure, is flexible and convenient to regulate, can be used in group and is convenient to level a large plane.

Description

technical field

[0001] The invention relates to the field of mechanical leveling, in particular to a small precision leveling device, which is suitable for the leveling of part planes or platform joint surfaces requiring precise leveling. Background technique

[0002] With the improvement of the design and manufacturing level of mechanical equipment, higher requirements are put forward for the adjustment of the levelness of parts or the adjustment of parallelism between parts in more equipment. It is time-consuming and labor-intensive to adopt the traditional gasket adjustment or screw top pressure method, and it is difficult to guarantee the adjustment effect. Especially in precision equipment with precise requirements for gap adjustment, such as die-cutting equipment that requires half-cut film, in order to ensure that the multi-layer flexible film material has a consistent depth of half-cut effect, it is necessary to adjust the plane of the die-cutter edge of the equipmen...
