Description

Technical Field

[0001] The invention belongs to the technical field of step difference detection, and in particular relates to a knife step difference comparison device and a use method thereof. Background Art

[0002] In order to achieve high maneuverability and pursue speed, the fuselage structure of the aircraft often requires lightweight aircraft parts 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 size of the web 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 deformation, 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 will have steps or tool marks. According to the design requirements, the tool table must not be larger than 0.01mm, and conventional measuring tools are not easy to measure 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. Summary of the invention

[0003] In view of the above problems, the object 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 tested is qualified when conventional measuring tools are not convenient for detection.

[0004] The present invention is achieved through the following technical solutions: A tool step difference comparison device comprises a reference block and a comparison block; the comparison blocks are multiple and are installed on one side of the reference block; the comparison blocks decrease in sequence from left to right compared with the horizontal plane of the reference block; the reference block is a rectangular parallelepiped; the comparison blocks are installed in sequence on one side of the long side of the reference block and are aligned with the edges on both sides of the reference block; the comparison blocks decrease in sequence from left to right with a difference of 0.01 mm.

[0005] A method for using a knife step difference comparison device comprises the following steps: 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.

[0006] 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 larger than the actual part step difference, the part step difference is less than 0.01mm, which meets the technical requirements and the test is qualified. Otherwise, if the step difference at the connection between the reference block and the comparison block is smaller than the actual part step difference, the part step difference is greater than 0.01mm, which meets the technical requirements and the test is unqualified.

[0007] The connection between the touch reference block and the comparison block in step b and the touch actual part step difference are touched by the left and right hands at the same time.

[0008] Beneficial effects of the present invention: The invention has a simple structure and is convenient and quick to operate. The step difference comparison device for the tool connection and the step difference of the part are quickly compared by touching the tool connection step difference comparison device with both hands to judge whether the part is qualified.
