Description

Technical Field

[0001] The utility model belongs to the technical field of step difference detection, and particularly relates to a knife step difference comparison device. Background Art

[0002] In order to achieve high maneuverability and pursue speed, the aircraft body structure often requires that the aircraft parts be lightweight without affecting the overall strength of the aircraft. To achieve this requirement, when designing large aircraft structural parts, the thickness is reduced to reduce the weight of the parts without affecting the strength and rigidity. Among them, the web size is controlled at 1.5-2mm. When processing the inner shape and the web, due to the small thickness of the web during processing, the workpiece clamping may be unstable, the workpiece itself may have deflection and deformation, and when two tools process the same plane, due to the objective existence of the tool being too small, the machine tool shaking or the tool wear, etc., the actual part may have steps or tool marks. According to the design requirements, the tool table must not be larger than 0.01mm. Conventional measuring tools are not convenient for measurement during inspection. Processors and inspectors cannot determine whether the steps or tool marks meet the tolerance requirements. Due to the lack of inspection standards, there are different disputes. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a tool step difference comparison device that can quickly determine whether the step difference of a part to be measured is qualified when conventional measuring tools are inconvenient for detection.

[0004] The utility model is realized through the following technical solutions:

[0005] A device for comparing tool step differences comprises a reference block and a comparison block; the comparison blocks are provided in a plurality and are mounted on one side of the reference block; the comparison blocks decrease in size from left to right compared with the horizontal plane of the reference block; the reference block is a rectangular parallelepiped; the comparison blocks are mounted on one side of the long side of the reference block and aligned with the edges on both sides of the reference block; the comparison blocks decrease in size from left to right with a difference of 0.01 mm.

[0006] A method for using a knife step difference comparison device comprises the following steps:

[0007] a. Check by touch and visually whether the reference block and comparison block are smooth and whether there are bumps and scratches on the surface.

[0008] b. Select the comparison block position corresponding to the step difference required for the component to be tested. For example, when the step difference required for the component to be tested is 0.02mm, select the second comparison block from the left to the right. After touching the step difference at the connection between the reference block and the comparison block, compare it with the actual part step difference. If the step difference at the connection between the reference block and the comparison block is greater than the actual part step difference, the part step difference is less than 0.01mm, meets the technical requirements, and passes the test. Conversely, if the step difference at the connection between the reference block and the comparison block is less than the actual part step difference, the part step difference is greater than 0.01mm, meets the technical requirements, and fails the test.

[0009] In the step b, the connection between the touch reference block and the comparison block and the touch actual part step difference are touched by the left and right hands simultaneously.

[0010] Beneficial effects of the utility model:

[0011] The utility model has the advantages of simple structure, convenient and quick operation, and can judge whether the part is qualified by quickly comparing the tool step difference comparison device and the part step difference by touching with both hands. BRIEF DESCRIPTION OF THE DRAWINGS
