Workbench flatness detection device

Abstract

The invention discloses a workbench flatness detection device, comprising a flat plate, a horizontal pipe I and a horizontal pipe II which are vertical to each other are arranged at the middle part ofthe upper end of the flat plate, screws connected by virtue of a screw thread are arranged at four corners of the lower end of the flat plate and midpoints of long sides, a gear motor I and a bearingblock I are fixed at the lower ends of the two sides of the flat plate, a lead screw I is arranged at the output terminal of the gear motor I, the lead screw I is coincided with a symmetric axis in the length direction of the flat plate, sliding rails I are arranged at the two sides of the lead screw I in parallel, a strut is arranged at the upper end of each sliding rail I, the struts are fixedon the lower end face of the flat plate, the lead screw I is provided with a movable plate I connected by virtue of a screw thread, a gear motor II and a bearing block II are respectively fixed at thetwo ends of the movable plate I, a lead screw II is arranged at the output terminal of the gear motor II, a movable plate II connected by virtue of a screw thread is arranged on the lead screw II, and a detector is arranged at the lower end of the movable plate II. The workbench flatness detection device disclosed by the invention controls movement of the detection device in the horizontal direction by utilizing the gear motor I and the gear motor II, flatness is detected by virtue of a dial gauge, an operation method is simple, and detection precision is high.

Description

technical field [0001] The invention belongs to the technical field of numerical control centers, and in particular relates to a workbench flatness detection device. Background technique [0002] The flatness of the working surface of the workbench is the main precision index to measure the quality of the workbench. The detection of the flatness of the existing CNC center worktable is generally carried out manually by using a level instrument or an adjustable bridge plate for flatness detection, and the detection accuracy is low. The operation is cumbersome and the work efficiency is low, which can no longer meet the mass production requirements of the CNC center workbench with higher flatness requirements. Contents of the invention [0003] According to the deficiencies of the prior art above, the technical problem to be solved by the present invention is to provide a workbench flatness detection device to solve the above-mentioned multiple defects caused by the prior art...
