Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of target roughness detection, and particularly relates to a tool for detecting the roughness of a target. Background Technique
[0002] The statements in this part are only to provide background information related to the technical solution of the present application to help understanding, and they do not necessarily constitute the prior art for the technical solution of the present application.
[0003] The front end of a traditional roughness meter has a measuring rod. When the probe on the measuring rod scans the workpiece to be measured, the surface profile of the workpiece is uneven, resulting in up and down displacements. These displacement information is output by the sensor and can obtain the roughness information of the workpiece surface after being processed by a computer. Currently, during the roughness test of high-purity metal targets, due to the special processing method, it is necessary to perform roughness tests on different points and different angles of the same point on the target surface or the upper side of the backplane. Generally, the measuring rod can only move up and down and move and test along the Y-axis direction within a certain range. When the orientation of the target does not meet the test requirements, our usual operation is to manually move the target to be measured to meet the test needs. However, frequent manual handling will increase the risk of scratching the finished target, and it is more difficult to move large-sized targets. Generally, two people are required to cooperate to move them, and the manual detection efficiency is low.
[0004] The prior art has made various improvements on the basis of the traditional roughness meter. The structure is cumbersome, and the strength of the components is not high. It is more suitable for measuring the roughness of small devices, and it cannot meet the requirements for roughness testing at different points and different angles of the same point, or the operation is complex. Therefore, it is necessary to propose a new tool that is simultaneously applicable to large-sized targets for roughness testing at different points and different angles of the same point. Summary of the Utility Model
[0005] In order to realize the roughness test of large-sized targets at different points and different angles of the same point, a tool for detecting the roughness of a target according to the present utility model is proposed. The specific technical solution is as follows:
[0006] A tool for detecting the roughness of a target material, comprising a mounting base plate, a slide rail and slider assembly, a slider mounting plate, a slewing bearing, and a target surface working platform. The slide rail and slider assembly includes a slide rail and a slider. The slide rail is fixedly arranged on the mounting base plate. A groove is formed in the lower part of the slider, and the shape of the groove matches the shape of the slide rail. The slider mounting plate is fixedly connected to the upper part of the slider. The slider mounting plate drives the slider to move along the slide rail. The slewing bearing is fixedly connected above the slider mounting plate, and the target surface working platform is fixedly connected above the slewing bearing. The slewing bearing can rotate 360° along the central axis. The slewing bearing is connected to the slider through the slider mounting plate and can move together with the slider. The target surface working platform is fixed above the slewing bearing, can rotate with the help of the slewing bearing, and can move together with the slider through the slewing bearing.
[0007] Further, the slide rail and slider assembly includes two slide rails and at least four sliders. The two slide rails are fixedly arranged in parallel on the mounting base plate. At least two sliders are fitted on each slide rail. Cylindrical anti-derailment welding blocks are welded at both ends of each slide rail to prevent the sliders from derailing. Preferably, there are four sliders, and two sliders are fitted on each slide rail. The two slide rails are fixedly arranged in parallel on the mounting base plate along the X-axis direction. The sliders can move freely along the slide rails in the X-axis direction, and the moving direction of the sliders is perpendicular to the testing direction of the roughness meter probe.
[0008] Further, both the slide rail and the slider are made of guide rail steel.
[0009] Further, the mounting base plate is an aluminum alloy plate. Threaded holes are evenly distributed in the middle of the mounting base plate. Screws pass through the threaded holes in the base plate to fixedly connect the mounting base plate to the desktop or tabletop. Specifically, the tabletop is a marble tabletop, and the mounting base plate is a 20-mm thick rectangular aluminum alloy plate. The long side of the mounting base plate is placed along the X-axis direction, and the mounting position can be adjusted according to the testing requirements.
[0010] Further, the slewing bearing is made of bearing steel, and the slider mounting plate is made of aluminum alloy. The outer ring of the slewing bearing is fixedly connected to the target surface working platform, and the inner ring of the slewing bearing is fixedly connected to the slider mounting plate. The outer ring of the slewing bearing can rotate freely 360° relative to the inner ring.
[0011] Further, the target surface working platform is made of aluminum alloy. At least four working table threaded holes are evenly formed in the center of the target surface working platform. The working table threaded holes are counterbores to avoid damage to the surface of the target material caused by the protrusion of the screws during the testing process. The contour formed by the working table threaded holes is consistent with the outer ring of the slewing bearing. Screws pass through the working table threaded holes to connect the target surface working platform to the outer ring of the slewing bearing below. Preferably, there are eight working table threaded holes.
[0012] Furthermore, an anti-collision electrostatic pad is pasted on the upper surface of the target surface working platform to prevent the workpiece from being bruised.
[0013] Among them, in the description of directions, the direction in which the probe on the front measuring rod of the roughness meter can move horizontally is defined as the Y-axis, and the direction perpendicular to the movement direction of the probe is the X-axis.
[0014] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:
[0015] 1. A tool for detecting the roughness of a target material provided by the present utility model, through the effective design and assembly of a slewing bearing and a slide rail slider assembly, can achieve the detection of the roughness at multiple points and multiple angles of a large-size (such as 12-inch) target material at one time without manual movement and adjustment of the position. During the test, through the effective adjustment of the slewing bearing and the slide rail slider assembly, the roughness at any point on the target material and in any direction at any point can be tested, that is, the roughness in the tangential direction and the vertical direction at the flange of the target material can be easily detected, improving the detection efficiency.
[0016] 2. The material component of the present utility model has relatively high strength and good structural design stability, can bear a long-term load of 300 kg, and is suitable for the detection of the roughness of large workpieces such as 12-inch target materials.
[0017] 3. The present utility model has a simple structure, flexible operation, and low use difficulty, which is beneficial to reducing costs and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will combine embodiments to detail the tool for detecting the roughness of a target material of the present application. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0022] A tool for detecting the roughness of a target material, comprising a mounting base plate 1 made of aluminum alloy plate, a slide rail and slider assembly 2 made of rail steel, a slider mounting plate 3 made of aluminum alloy plate, a slewing bearing 4 made of bearing steel, and a target surface working platform 5 made of aluminum alloy. The middle of the mounting base plate 1 is evenly distributed with base plate threaded holes 11. Screws fix the mounting base plate 1 to the marble tabletop through the base plate threaded holes 11. The mounting base plate 1 is specifically a rectangular aluminum alloy plate with a thickness of 20 mm. The long edge of the mounting base plate 1 is placed in the X-axis direction and can be adjusted according to the test requirements, mainly playing a role in fixing and supporting the whole tool.
[0023] The slide rail and slider assembly 2 is a component for realizing telescopic displacement, including two slide rails 21 and four sliders 22. The two slide rails 21 are fixedly arranged on the mounting base plate 1 in parallel along the X-axis direction. Grooves are formed under the sliders 22, and the shape of the grooves matches the shape of the slide rails 21. Two sliders 22 are arranged on each slide rail 21. Cylindrical anti-derailment welding blocks 23 are welded at both ends of each slide rail 21, which can prevent the sliders 22 from sliding along the X-axis to the end of the slide rail 21 and getting out of the track. The sliders 22 can move freely along the slide rails 21 in the X-axis direction, and the moving direction of the sliders 22 is perpendicular to the testing direction of the roughness meter probe. This component can indirectly drive the target material to perform telescopic movement along the X-axis direction through the movement of the sliders 22.
[0024] The slider mounting plate 3, the slewing bearing 4, and the target surface working platform 5 form a rotating device, which can realize the 360° unobstructed rotation of the target material along the target center. The lower surface of the slider mounting plate 3 is fixedly connected to the upper part of the slider 22. The slider mounting plate 3 can move along the slide rail 21 driven by the slider 22, and the slider mounting plate 3 mainly plays a role in connecting the telescopic displacement device and the rotating device. The slewing bearing 4 is fixedly connected above the slider mounting plate 3, and the target surface working platform 5 is fixedly connected above the slewing bearing. Eight working platform threaded holes 51 are evenly formed at the center of the target surface working platform 5. The working platform threaded holes 51 are counterbores, and the contour formed by the working platform threaded holes 51 is consistent with the outer ring of the slewing bearing 4. Screws connect the target surface working platform 5 to the outer ring of the slewing bearing 4 below through the working platform threaded holes 51. The inner ring of the slewing bearing 4 is fixedly connected to the slider mounting plate 3. The outer ring of the slewing bearing 4 can rotate freely by 360° relative to the inner ring. The slewing bearing 4 is connected to the slider 22 through the slider mounting plate 3 and can move together with the slider 22. The target surface working platform 5 is fixed above the slewing bearing 4, can rotate with the help of the slewing bearing 4, and can move together with the slider 22 through the slewing bearing 4. An anti-collision and anti-static pad is also pasted on the upper surface of the target surface working platform 5, and both it and the counterbore-designed working platform threaded holes are for preventing the workpiece from being bruised or scratched.
[0025] In order to meet the test requirements of the target material roughness, the specific operation can be decomposed into two parts.
[0026] The first part is multi-point testing. Since the stylus of the roughness meter can only move along the Y-axis direction, the target material to be measured can be placed on the target surface working platform 5, with the center of the target coinciding with the center of the target surface working platform 5. By moving the slider 22, the position of the target surface along the X-axis can be adjusted so that the moving direction of the stylus passes through the center of the target surface. By driving the rotation of the target material through the slewing bearing 4, the roughness of different points on the same circumference of the target material can be measured. Moving the position of the stylus can change the diameter of the circumference, and thus the roughness of any point on the entire target surface can be measured at one time without manually moving the target material. During the testing process, the testing direction of the stylus is along the Y-axis direction. When testing according to the above method, only the roughness in one direction, i.e., along the center direction, of a certain point can be measured.
[0027] The second part is multi-angle testing, which focuses on the testing of the roughness at the same point with different angles. As a relatively preferred implementation manner in this embodiment, the target material to be measured can be placed on the target surface working platform 5, with the center of the target coinciding with the center of the target surface working platform 5. Select any point A on the target surface in the manner described in the first part, and the roughness of point A along the direction of the target center can be measured. Rotate the target surface clockwise by a certain angle, denoted as α, through the slewing bearing 4. At this time, point A has deviated from the testing direction of the stylus. Drive the movement of the target surface by moving the slider 22, and move point A along the X-axis direction to the straight line where the testing direction of the stylus is located. Adjust the position of the stylus in the Y-axis direction, and the roughness information of point A along the Y-axis direction can be measured. The deflection angle between this direction and the direction from point A to the target center is α, where α can be any value between 0° and 360°. By adjusting in this way, the roughness information of point A in any direction can be measured.
[0028] By adopting the above-mentioned tooling assembly structure and testing method, the target material can be easily detected at multiple points and multiple angles without manually moving the target material during the testing process.
[0029] The above is only used to illustrate the technical solution of the present invention, rather than to limit it. Any person skilled in the art who makes simple modifications, equivalent replacements, and modifications within the technical scope disclosed by the present invention shall fall within the protection scope of the technical solution of the present invention.
