Description

Technical Field

[0001] This application relates to the field of alloy blade technology, and in particular to an alloy blade measuring device. Background Technology

[0002] In mechanical metal cutting, alloy inserts are widely used due to their advantages of large cutting volume and large feed rate.

[0003] However, in the production process of cemented carbide, the product is pressed into shape from powder and then sintered at high temperature to cause shrinkage and hardening, resulting in our existing cemented carbide inserts. Due to the different coefficients of thermal expansion between the carbides and the binder phase in cemented carbide, which consists of high-hardness carbides (such as WC, TiC, etc.) and metallic binder phases (usually cobalt, nickel, etc.), internal stress is generated after high-temperature sintering, leading to localized deformation of the product. This results in poor product precision and typically requires grinding of both the top and bottom surfaces.

[0004] Current measurement technologies, limited to micrometers or platform height gauges, suffer from significant measurement errors. Without comprehensive measurement data, they cannot support subsequent improvements, process direction, or process routing, offering limited assistance to later processing and resulting in limited improvement in product accuracy after grinding. Micrometer measurements are generally point-to-point; however, due to significant deformation of cemented carbide products after sintering, point-to-point measurements only reflect the height of the measured point, not the overall height and deformation of the product. Platform height gauge measurements involve placing the product on a platform, but due to cemented carbide deformation, measuring different points may yield multiple planar measurement data. Furthermore, the random selection of measurement points leads to large errors. Consequently, existing measurement methods are not fully applicable in areas such as data support, product improvement, and cost reduction. Utility Model Content

[0005] This application provides an alloy cutting tool measuring device that provides accurate data support, helps to determine product improvement directions and process routes, improves production qualification rate, and reduces production costs.

[0006] This application provides an alloy blade measuring device comprising a friction imprint device for locating the deformed protrusions of the alloy blade and a moving measuring device for detecting the amount of deformation of the alloy blade. The alloy blade rotates in contact with the friction imprint device to highlight the friction imprint, and multiple marking points are distributed outwardly along the friction imprint on the alloy blade. The moving measuring device comprises: a positioning frame assembly, a measuring frame slidably mounted on the positioning frame assembly, and a measuring component slidably mounted on the measuring frame. A stop bar is mounted parallel to the X or Y direction on the positioning frame assembly, and the side of the alloy blade is attached to the stop bar and fixedly mounted on the positioning frame assembly. The measuring frame... The measuring component slides longitudinally along a first direction, and the positioning frame assembly is equipped with a first measuring ruler for measuring the sliding distance of the measuring frame; the measuring component slides laterally along a second direction, and the measuring frame is equipped with a second measuring ruler for measuring the sliding distance of the measuring component; the measuring component slides vertically along a third direction, and the measuring component is equipped with a third measuring ruler for measuring the sliding distance of the probe of the measuring component; the alloy blade measuring device also includes a modeling system, which collects the movement measurement data of the measuring component along any marked point toward the corresponding friction mark direction, and forms a corresponding size model in the modeling software from multiple movement measurement data.

[0007] In this application, a simple method is used to locate and highlight friction marks, with the tip of the alloy blade as the marker point. The alloy blade face is fixed to the positioning frame assembly with the measurement surface horizontal. The measuring frame and measuring components are moved, using multiple marker points as a unified base point. The probe of the measuring component moves along the marker points toward the highlighted friction marks, simultaneously acquiring movement data in multiple directions. After constructing a virtual plane and obtaining accurate data support, the modeling system generates a corresponding model after inputting precise values. By comparing the deformed model with the actual design product model data, the actual deformation of the product can be obtained. Based on the product's deformation, the processing direction or process route can be determined, reducing the product scrap rate and improving product accuracy. During the product design process, product parameters can be appropriately modified to reduce deformation, improve product qualification rate, and achieve the goal of cost reduction and efficiency improvement.

[0008] In one specific implementation, the friction imprint device includes: a metallographic sandpaper platform and a positioning screw; wherein the central axis end of the alloy blade rotates circumferentially along the positioning screw, and the upper and / or lower surfaces of the alloy blade are in frictional contact with the metallographic sandpaper platform. A simple positioning process is employed to accurately obtain the deformed protrusion position of the alloy blade, and frictional loss is negligible.

[0009] In one specific implementation, the positioning frame assembly includes: a positioning base plate and a gantry frame assembly connected to the positioning base plate; wherein the stop bar is fixedly mounted on the positioning base plate; and the measuring frame slides longitudinally along the top of the gantry frame assembly. Multi-directional measurement data acquisition is achieved by employing a lower positioning and upper measurement method.

[0010] In one specific implementation, the stop lever is a rectangular rod with a contact surface parallel to the side of the alloy blade. Positioning is achieved based on the parallelism of the alloy blade's side surface, ensuring that the measuring surface of the alloy blade is a uniform reference plane.

[0011] In one specific implementation, the measuring frame is a frame-shaped structure, and the measuring component slides laterally along the inner frame of the measuring frame. This provides a stable lateral sliding measurement effect.

[0012] In one specific implementation, the measuring component is mounted on the measuring frame via a sliding frame, and the third measuring ruler is mounted on the sliding frame along the Z-direction. The third measuring ruler collects vertical height measurement data.

[0013] In one specific implementation, the probe of the measuring component sequentially measures data in the Y, X, and Z directions along the plurality of marked points corresponding to the plurality of friction marks. Moving the measurement data ensures synchronous and accurate measurement. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0018] To facilitate understanding of the alloy cutting tool measuring device provided in this application embodiment, its application scenario is first explained. In the cemented carbide production process, the product is pressed into shape using powder, and then sintered at high temperature to cause shrinkage and hardening, resulting in our existing cemented carbide cutting tools. Due to the different coefficients of thermal expansion between carbides and the binder phase in cemented carbide, which consists of high-hardness carbides (such as WC, TiC, etc.) and metallic binder phases (usually cobalt, nickel, etc.), internal stress is generated after high-temperature sintering, leading to local deformation of the product. The product has poor accuracy and usually requires grinding of the upper and lower end faces. Existing measurement technologies can only measure the product using micrometers or height gauges, resulting in large measurement errors. Without comprehensive measurement data, it is impossible to provide data support for subsequent improvements and the formulation of product process directions and routes, offering limited assistance to subsequent processing. The improvement in product accuracy after grinding is also limited. Consequently, existing measurement methods cannot be fully applied in many aspects such as data support, product improvement, and cost reduction. In view of this, this application provides an alloy cutting tool measuring device that provides accurate data support, helps to formulate product improvement directions and process routes, improves production qualification rate, and reduces production costs.

[0019] To facilitate the description of the measuring device and method for the alloy cutting tool provided in the embodiments of this application, an X, Y, Z coordinate system is first established, wherein the X direction is the horizontal longitudinal direction, the Y direction is the horizontal transverse direction, the Z direction is the vertical direction, and both the X and Y directions are perpendicular to the X direction.

[0020] refer to Figures 1-2As shown in the figure, the alloy blade 10 measuring device provided in this application includes a friction imprint device for locating the deformed protruding position of the alloy blade 10; the friction imprint device is used to highlight the friction imprint of the protruding position according to the amount of deformation of the alloy blade 10. After being rubbed by the friction imprint device, the alloy blade 10 emits a bright spot after being rubbed at the deformed protruding position, which is different from the surface color of the alloy blade 10, so as to achieve accurate positioning during the measurement process. Moreover, the overall equipment is simple and inexpensive.

[0021] Specifically, the friction imprint device includes a metallographic sandpaper platform 1 and a positioning screw 2. The central axis of the alloy blade 10 rotates circumferentially along the positioning screw 2, and the upper and / or lower surfaces of the alloy blade 10 are in frictional contact with the metallographic sandpaper platform 1. A simple positioning process is used to accurately obtain the deformed protrusion position of the alloy blade 10, and frictional loss is negligible. As can be seen from the above structure, after the positioning screw 2 passes through the central hole of the alloy blade 10, the alloy blade 10 is positioned on the metallographic sandpaper platform 1. The alloy blade 10 must not wobble after being positioned on the metallographic sandpaper platform 1, but either the upper or lower surface of the alloy blade 10 can rotate while adhering to the metallographic sandpaper platform 1. The alloy blade 10 is placed on the metallographic sandpaper platform 1, and to ensure the accuracy of the measurement plane, it is fixed by the screw 2 to prevent the alloy blade 10 from wobble, while also allowing the alloy blade 10 to rotate on it. Rotate the alloy blade 10 on the metallographic sandpaper platform 1 to make it rub against the metallographic sandpaper, leaving relatively obvious friction marks on the surface of the alloy blade 10. The friction marks of the product can be used as the measurement reference surface of the product.

[0022] like Figure 2 As shown, Figure 2 The diagram shows the use of a polygonal cutting insert as the alloy insert 10, and indicates the distribution of friction marks and marked points. Of course, in other embodiments of this application, the alloy insert 10 can also be a prismatic insert, a square insert, etc., which will not be elaborated on here. Figure 2 As shown, the three tip positions of the alloy blade 10 are designated as marker points: marker point a, marker point b, and marker point c; the corresponding friction marks a formed on the upper or lower surface of the alloy blade 10 after circumferential rotation on the metallographic sandpaper platform 1. 1 Friction marks a 2 Friction marks a 3 Marker points a, b, and c are used as measurement reference points, located on the same plane, and forming the same set angle α (120°) between them. Therefore, it can be seen that using marker point a as the reference point corresponds to the friction mark a. 1Data was collected in the X, Y, and Z directions, with the marked point b as the base point corresponding to the friction imprint b. 1 Data was collected in the X, Y, and Z directions, with the marked point c as the base point corresponding to the friction imprint c. 1 Data is collected in the X, Y, and Z directions. This ensures that the three marker points are located on the same plane, greatly improving the accuracy of data acquisition.

[0023] refer to Figure 3 and Figure 4 As shown, the mobile measuring device in this application includes: a positioning frame assembly 20; a stop bar 24 is mounted parallel to the X or Y direction on the positioning frame assembly 20, and the side of the alloy blade 10 is attached to the stop bar 24 and fixedly mounted on the positioning frame assembly 20; in a specific embodiment of this application, the stop bar 24 is fixedly mounted on the positioning frame assembly 20 along the Y direction. The positioning frame assembly 20 includes: a positioning base plate 21 and a gantry assembly 22 connected to the positioning base plate 21; wherein, the stop bar 24 is fixedly mounted on the positioning base plate 21; the measuring frame 30 slides longitudinally along the top end of the gantry assembly 22. Multi-directional measurement data acquisition is achieved by using a lower positioning and upper measurement method. Figure 5 As shown, the stop lever 24 is a rectangular rod with a contact surface parallel to the side of the alloy blade 10. Positioning is achieved based on the parallelism of the side of the alloy blade 10, ensuring that the measuring surface of the alloy blade 10 is a uniform reference plane.

[0024] As can be seen from the above structure, after the alloy blade 10 has a prominent friction mark after passing through the friction mark device, the alloy blade 10 is fixed on the positioning base plate 21. During the fixing process, it is ensured that the side of the alloy blade 10 and the contact surface of the stop bar 24 are completely in contact, thereby ensuring that the three marking points are located on the same plane for subsequent measurement operations.

[0025] The mobile measuring device also includes a measuring frame 30 slidably mounted on the positioning frame assembly 20, and a measuring component 40 slidably mounted on the measuring frame 30. In this application, the measuring frame 30 is slidably connected to the top of the gantry assembly 22 via a sliding groove. Furthermore, the measuring frame 30 is a frame-shaped structure, and the measuring component 40 slides laterally along the inner frame of the measuring frame 30. This provides a stable lateral sliding measurement effect.

[0026] The measuring frame 30 slides longitudinally along a first direction, which is the X direction, and the positioning frame assembly 20 is equipped with a first measuring ruler 23 for measuring the sliding distance of the measuring frame 30; the first measuring ruler 23 unfolds along the X direction and is used to measure the sliding distance data of the sliding frame.

[0027] The measuring component 40 slides laterally along a second direction, which is the Y direction, and a second measuring ruler 31 for measuring the sliding distance of the measuring component 40 is mounted on the measuring frame 30; the second measuring ruler 31 unfolds along the Y direction and is used to measure the sliding distance data of the measuring component 40.

[0028] The measuring component 40 slides vertically along a third direction, which is the Z direction, and a third measuring ruler 32 for measuring the sliding distance of the probe of the measuring component 40 is mounted on the measuring component 40; the third measuring ruler 32 and the measuring component 40 can be a platform height gauge assembly.

[0029] The measuring component 40 is mounted on the measuring frame 30 via a sliding frame, and a third measuring ruler 32 is mounted on the sliding frame along the Z-direction. The third measuring ruler 32 collects vertical height measurement data. The probe of the measuring component 40 sequentially measures data in the Y, X, and Z directions along multiple marked points corresponding to multiple friction marks. Moving the measurement data achieves synchronous and accurate measurement.

[0030] By moving along the corresponding marked points towards the corresponding friction marks, measurements are taken. During the measurement process, the values ​​on the first measuring ruler 23, the second measuring ruler 31, and the third measuring ruler 32 are observed and recorded to obtain accurate data support.

[0031] In addition, the alloy blade 10 measuring device in this application also includes a modeling system. The modeling system collects the movement measurement data of the measuring component 40 along any marked point toward the corresponding friction mark direction, and forms a corresponding size model from multiple movement measurement data in the modeling software. It should be specifically noted that generating a model of the same size by inputting data into the modeling system is a basic operation in existing modeling systems, and will not be elaborated on here.

[0032] In this application, a simple method is used to locate and highlight friction marks. The tip of the alloy blade 10 is used as the marker point, and the alloy blade surface is fixed on the positioning frame 20 with the measuring surface horizontal. The measuring frame 30 and the measuring component 40 are moved, using multiple marker points as a unified base point. The probe of the measuring component 40 moves along the marker points toward the highlighted friction marks to measure, simultaneously acquiring movement data in multiple directions. After obtaining accurate data support, the modeling system generates a corresponding model after inputting precise values. By comparing the deformed model with the actual design product model data, the actual deformation of the product can be obtained. Based on the product deformation, the processing direction or process route of the product can be determined, reducing the scrap rate and improving the product accuracy. During the product design process, the product parameters can be appropriately modified to reduce the amount of deformation, improve the product qualification rate, and achieve the purpose of cost reduction and efficiency improvement.

[0033] Furthermore, this application also provides a method for measuring alloy cutting tools, including a method using the aforementioned alloy cutting tool measuring equipment, comprising the following steps: S1: Locate the protruding position based on the sintering deformation of the alloy blade, and highlight the friction mark on the friction mark device; S2: Select marker points by expanding outwards along multiple friction marks; S3: Using an alloy blade measuring device, measure sequentially along the marked points toward the corresponding friction marks to obtain deformation measurement data of the upper and / or lower surfaces of the alloy blade. S4: Input the measurement data into the modeling system to form the corresponding model.

[0034] The distance between any two adjacent marker points is a set angle α. This set angle α is preferably 120°. In other embodiments of this application, the angle α may be less than 120° during product deformation. The alloy blade measuring device simultaneously measures the movement values ​​in the X, Y, and Z directions of the upper and / or lower surfaces of the alloy blade.

[0035] In this application, the above methods are used to provide accurate data support, formulate product improvement directions and process routes, improve production qualification rate, and reduce production costs.
