Description

Technical Field

[0001] This utility model belongs to the field of blade inspection, specifically a device for detecting the flatness of a blank blade. Background Technology

[0002] Raw inserts are the initial form of cutting tool manufacturing in the field of cutting processing. Their geometric accuracy, material properties and surface condition directly affect the efficiency of subsequent finishing and the final quality of the tool. The flatness of the raw insert is the core indicator that determines the subsequent cutting edge machining accuracy, coating uniformity and tool life. Therefore, flatness inspection is an essential task in the production process of raw inserts.

[0003] Dial indicators are commonly used tools for inspecting the flatness of blank cutting tools. They are often used in the inspection of blank cutting tools with low production volume. When using dial indicators to inspect blank cutting tools, the operator needs to manually push the cutting tool to move frequently. During the movement, due to the influence of the operator's personal operation, it is difficult to ensure that the cutting tool moves in a straight line, which will systematically introduce various errors such as trajectory offset error, Abbe error, and repeatability error, significantly affecting the accuracy and reliability of the inspection results.

[0004] In summary, this utility model provides a blank blade flatness detection device to solve the above problems. Utility Model Content

[0023] Example 1

[0024] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a blank blade flatness detection device, including,

[0025] The detection unit 1 includes a base plate 101, a marble pad 102 fixedly connected to the inner cavity of the base plate 101, a magnetic base 103 fixedly connected to the top rear end of the base plate 101, a dial indicator 104 disposed on one side of the magnetic base 103, and a placement component 105 disposed on the top of the base plate 101.

[0026] The adjustment unit 2 includes support blocks 201 disposed on both sides of the top of the base plate 101, a limiting component 202 disposed between the two support blocks 201, and a moving component 203 disposed in the inner cavity of the base plate 101.

[0027] like Figure 1-4As shown, the base plate 101 serves as the basic support structure for the entire device, bearing and fixing other components to ensure overall stability. The marble pad 102 is made of grade 0 precision marble with a flatness error ≤0.001mm / 300mm, meeting the requirements for precision testing. As a high-precision measurement reference surface, it supports the testing area and ensures the flatness reference standard. The magnetic base 103 fixes the dial indicator 104, providing adjustable support and positioning functions. The dial indicator 104 directly measures the height difference between various points on the blade surface, quantifying the flatness error. The placement component 105 is used to bear and fix the blank blade, ensuring that it is parallel and stable to the reference surface. The support block 201 is used to support the placement component 105 and transmit the displacement of the adjustment unit 2. The limiting component 202 is used to constrain the movement trajectory of the placement component 105 to prevent deviation or tilting. The moving component 203 drives the placement component 105 to move horizontally or vertically, achieving full coverage testing of the blade surface.

[0028] Example 2

[0029] Reference Figure 1 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] In this embodiment, the placement component 105 includes a placement plate 1051 disposed on the top of the base plate 101, magnetic posts 1052 fixedly connected to the top periphery of the placement plate 1051, and magnetic blocks 1053 magnetically connected to the top of the magnetic posts 1052.

[0031] The placement component 105 also includes an inclined plate 1054 fixedly connected to the right side of the magnetic base 103, and a pen holder 1055 fixedly connected to the top right side of the base plate 101.

[0032] like Figure 1 and 3 As shown, the magnetic column 1052 and the magnetic block 1053 achieve stress-free fixation, which can prevent the blade from deforming while fixing the blade to the top of the placement plate 1051. Paper can be laid on the top of the inclined plate 1054 for data recording, and the pen holder 1055 is used to place pens.

[0033] Example 3

[0034] Reference Figure 2-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0035] In this embodiment, the support block 201 includes a limiting post 2021 fixedly connected to the front and rear ends of the two support blocks 201, and a limiting sleeve 2022 slidably connected to the surface of the limiting post 2021. The top of the limiting sleeve 2022 is fixedly connected to the bottom of the placement plate 1051.

[0036] The movable component 203 includes a receiving groove 2031 opened on the top right side of the base plate 101, a threaded rod 2032 movably connected to the inner cavity of the receiving groove 2031 via a bearing, and a threaded block 2033 threadedly connected to the surface of the threaded rod 2032. The top of the threaded block 2033 is fixedly connected to the bottom of the right support block 201.

[0037] The moving component 203 also includes a slide groove 2034 formed on the top left side of the base plate 101, and a pulley 2035 fixedly connected to the front and rear ends of the bottom of the left support block 201. The pulley 2035 is slidably connected to the inner cavity of the slide groove 2034.

[0038] like Figure 2-4 As shown, the clearance between the limiting post 2021 and the limiting sleeve 2022 is ≤0.01mm to ensure the straightness of the movement. The double-post structure effectively resists the lateral force during measurement and improves stability. The limiting sleeve 2022 uses a self-lubricating copper sleeve with a friction coefficient ≤0.1, which reduces movement resistance. The threaded rod 2032 has a pitch of 0.5mm and works with the threaded block 2033 to achieve 0.01mm-level steps. The threaded pair has a self-locking function to prevent the blade position from shifting during measurement. The pulley 2035 works with the slide groove 2034 to reduce movement vibration.

[0039] When using the device, the testing should be conducted in an environment with suitable temperature and humidity. First, place the device on a flat surface and calibrate it. Place the blade to be tested on the top of the placement plate 1051. After placement, use four magnetic blocks 1053 to position the four corners of the blade. The clamping force exerted on the blade by the magnetic column 1052 and the magnetic blocks 1053 should be ≤0.5N. Next, adjust the position of the dial indicator 104 using the magnetic base 103 so that the probe of the dial indicator 104 contacts the surface of the blade. Then, push the placement component 105 to move it left and right on the top of the marble pad 102. During the movement, take a measurement point every 10-20mm. When pushing the placement component 105 by hand, the speed should be ≤5mm / s to avoid impact load. Measure twice in the opposite direction at each point and take the average value to eliminate backlash error. Observe the reading of the dial indicator 104. While observing, paper can be placed on the top of the inclined plate 1054 to record the readings, thereby checking the flatness of the blade.
