Abstract
Description
Technical Field
[0001] The present application relates to the field of heat treatment technology, and in particular to a coupling gap inspection device. Background Art
[0002] Surface induction hardening is widely used in the manufacture of crankshafts, cams, wind turbine bearings, shield machine bearings and other parts. Before induction hardening, the coupling gap between the inductor and the workpiece is determined according to the process parameters, which is called tool setting.
[0003] The coupling gap between the inductor and the workpiece is the most important parameter in the entire induction hardening process. When batch processing parts, the consistency of the coupling gap is the guarantee of process and quality stability. In some factories, old machine tools are still used for operation. Old machine tools do not have CNC systems and require operators to manually control the coupling gap. Usually, operators measure the gap with a feeler gauge or observe the gap with the naked eye when setting the tool.
[0004] Feeler gauges generally have only millimeter-level accuracy and are prone to bending during use. There are gaps between adjacent feeler gauges, which makes the measurement results inaccurate and even more inaccurate when observed with the naked eye, resulting in inconsistent coupling gap sizes for each processing, which in turn affects the quality of surface quenching.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0028] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0029] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0030] Surface induction hardening is widely used in the manufacture of crankshafts, cams, wind turbine bearings, shield machine bearings and other parts. Before induction hardening, the coupling gap size between the sensor and the workpiece will be determined according to the process parameters, which is called tool setting. That is, the distance between the sensing surface of the sensor and the surface to be processed of the workpiece is determined. The induction heating effect is very sensitive to the size of the coupling gap, and fluctuations at the micrometer level can also cause large temperature changes on the surface of the workpiece. If the coupling gap is too small, the electromagnetic skin effect is too strong, which will cause the workpiece temperature to be too high, the structure to be coarse, and even the workpiece to crack. If the coupling gap is too large, the workpiece temperature will be low, and the ideal austenitizing temperature cannot be reached, making the hardness and hardened layer depth unqualified.
[0031] Some factories are still using old-fashioned machine tools for operation. Old-fashioned machine tools do not have numerical control systems, so the size of the coupling gap cannot be accurately determined and manual tool setting is required. During the manual tool setting process, the operator needs to adjust the position of the sensor on the machine tool to adjust the coupling gap with the workpiece surface to be processed to meet production requirements.
[0032] Usually, operators use feeler gauges to measure the gap or observe the gap with the naked eye when setting the tool. Feeler gauges generally have only millimeter-level accuracy and are easy to bend during use. There are gaps between adjacent feeler gauges, making the measurement results inaccurate, and visual observation is even more inaccurate, resulting in inconsistent coupling gap sizes for each processing, which in turn affects the quality of surface quenching.
[0033] In order to solve the above problems, the present application provides a coupling gap inspection device, which can quickly detect the coupling gap of the tool setting through the detection plane set on the substrate, improve the tool setting accuracy, ensure the consistency of the coupling gap in each processing, and improve the stability of the quality of induction quenching on the workpiece surface; at the same time, the coupling gap between the workpiece and the surface induction quenching sensor during tool setting can be quickly read through the mark, thereby reducing the calculation time and improving the efficiency; and the substrate is a plastic part with good insulation properties, which will not cause the surface induction quenching sensor to be grounded, and is simple to manufacture and easy to use.
[0034] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0035] The present application provides a coupling gap inspection device,
[0036] Reference Figure 1 and Figure 2The coupling gap inspection device includes a substrate 100, on which a plurality of detection planes 200 are arranged. The detection planes 200 are parallel to the bottom surface of the substrate 100, and the distances between the detection planes 200 and the bottom surface of the substrate 100 are all different. A mark is arranged on the substrate 100, and the mark is used to mark the distance information between the detection plane 200 and the bottom surface of the substrate 100.
[0037] The detection plane 200 is directly formed on the substrate 100 . In other embodiments, the detection plane 200 may also be formed by cutting on the substrate 100 . No excessive limitation is made here.
[0038] The detection plane 200 is parallel to the bottom surface of the substrate 100. During the use of the device, the coupling gap between the sensor 2 and the workpiece 1 is adjusted, that is, the tool setting operation is first performed, and then the bottom surface of the substrate 100 is placed on the workpiece 1, so that one of the detection planes 200 is in contact with the sensor 2. At this time, the distance between this detection plane 200 and the bottom surface of the substrate 100 is the coupling gap of the workpiece 1. The position detection of the sensor 2 is adjusted again to make the coupling gap of the workpiece 1 meet the design requirements, improve the tool setting accuracy, ensure the consistency of the coupling gap each time processing, and improve the stability of the induction quenching quality of the workpiece 1 surface.
[0039] In some embodiments, reference Figure 1 and Figure 2 , the distance between the detection plane 200 and the bottom surface of the substrate 100 increases successively.
[0040] The distance between the detection plane 200 and the bottom surface of the substrate 100 increases in sequence, so that the substrate 100 is in a step shape, rising from one end of the substrate 100 toward the other end in sequence, and each step surface is the detection plane 200. When in use, adjust the position of the sensor 2, perform tool setting, and then place the substrate 100 on the workpiece 1, and push the lower end of the detection plane 200 on the substrate 100 toward the sensor 2, until one of the detection planes 200 on the substrate 100 contacts the sensor 2 plane. At this time, the distance from this detection plane 200 to the bottom surface of the substrate 100 is the coupling gap of the workpiece 1 at this time.
[0041] Furthermore, when in use, the substrate 100 can be placed on the surface to be processed of the workpiece 1, and the detection plane 200 on the substrate 100 corresponding to the coupling gap required for processing the workpiece 1 can be placed directly below the sensor 2, and then the position of the sensor 2 can be adjusted to perform the tool setting operation so that the sensor 2 contacts the corresponding detection plane 200, and then the substrate 100 can be removed, thereby achieving precise control of the coupling gap and improving the tool setting accuracy, so as to ensure the consistency of the coupling gap in each processing and improve the stability of the induction quenching quality of the surface of the workpiece 1.
[0042] The distances between adjacent detection planes 200 can be set to be different. In this way, the detection plane 200 on the substrate 100 can be designed with corresponding coupling gaps according to the corresponding workpieces 1 processed in batches, and the different coupling gaps of multiple workpieces 1 can be integrated on the same substrate 100 and arranged in order from low to high, without being limited by the detection accuracy of the detection plane 200 of the substrate 100. Different detection accuracies can be set on the same substrate 100, and the detection of the workpiece 1 is also convenient. The identification on the substrate 100 marks different detection planes 200 to prevent operators from using them incorrectly, further improving the accuracy of detection.
[0043] The spacing between adjacent detection planes 200 is greater than or equal to 0.08 mm and less than or equal to 0.22 mm.
[0044] For example, refer to Figure 1 and Figure 2 , the spacing between adjacent detection planes 200 is 0.1mm. This makes the minimum measurement accuracy of the detection plane 200 0.1mm, and the tool setting accuracy is also improved to 0.1mm accordingly. Compared with the millimeter-level feeler gauge, the measurement accuracy is improved to the decimeter level, thereby improving the detection accuracy.
[0045] Of course, in other embodiments, the spacing between adjacent detection planes 200 can be set according to actual accuracy requirements, for example, the spacing between adjacent detection planes 200 can be set to 0.2 mm, etc., as long as the corresponding measurement accuracy requirements are met, and no excessive restrictions are made here.
[0046] Among them, refer to Figure 1 and Figure 2 , the minimum distance from the detection plane 200 to the bottom surface of the substrate 100 is greater than or equal to 1.8 mm and less than or equal to 2.2 mm.
[0047] In the embodiment of the present application, the minimum distance from the detection plane 200 to the bottom surface of the substrate 100 is 2 mm, so that the detection plane 200 gradually increases from 2 mm, thereby reducing the number of steps of the substrate 100, thereby reducing the length of the substrate 100, and the substrate 100 can be quickly moved to contact with the sensor 2, and the coupling gap can be quickly detected. At the same time, after the length of the substrate 100 is reduced, it is convenient for the operator to carry the substrate 100, and the weight of the substrate 100 is reduced, reducing the possibility of the substrate 100 breaking at a weak point.
[0048] Of course, in other implementations, the minimum distance from the detection plane 200 to the bottom surface of the substrate 100 can be set to different values according to actual conditions, as long as it can meet the corresponding measurement requirements, and no excessive restrictions are made here.
[0049] Reference Figure 1 and Figure 2 , the width of the detection plane 200 is greater than or equal to 20 mm.
[0050] In the present application, the width of the detection plane 200 is 20 mm. Sufficient width is conducive to placing the sensor 2 on the corresponding detection plane 200 during the detection of the coupling gap, making it easier to read the mark corresponding to the detection plane 200, thereby improving the convenience of operation.
[0051] In other embodiments, the width of the detection plane 200 is greater than or equal to the width of the sensor 2, so that when the device is in use, the sensor 2 can be completely placed on the detection plane 200 to facilitate the detection of the coupling gap.
[0052] Exemplarily, the number of detection planes 200 on the substrate 100 is set to 11, wherein the minimum distance between the detection plane 200 and the bottom surface of the substrate 100 is 2 mm, the distance between adjacent detection planes 200 is 0.1 mm, and the distance between the detection plane 200 and the bottom surface of the substrate 100 increases successively from one end of the substrate 100 toward the other end, forming a detection range of 2mm-3mm for the coupling gap of the tool, and a detection accuracy of 0.1mm.
[0053] Among them, refer to Figure 1 , the identification and the detection plane 200 are set in one-to-one correspondence.
[0054] The number of the marks is the same as that of the detection planes 200 and they are arranged near the corresponding detection planes 200. The specific information of the corresponding detection planes 200 can be directly and quickly read out through the marks, so as to quickly determine the coupling gap.
[0055] In other embodiments, multiple marks may be arranged at intervals on the substrate 100, that is, there is only one mark for each adjacent detection plane 200, so that the coupling gaps corresponding to all detection planes 200 may be obtained by the arrangement rules of the corresponding detection planes 200, thereby avoiding the possibility of overlapping due to too many marks.
[0056] Furthermore, the identification is a recognizable identification word 300 .
[0057] The identification character 300 is the distance from the corresponding detection plane 200 to the bottom of the substrate 100, so that the corresponding coupling gap can be directly read out, which reduces the calculation process and improves the operation efficiency.
[0058] In some embodiments, the logo is disposed on a side wall of the substrate 100 .
[0059] The logo is directly integrally formed on the side wall of the base 100 to facilitate reading of the logo from the side.
[0060] In other implementations, the mark may also be disposed on the corresponding detection plane 200 , that is, the mark may be read from the upper surface.
[0061] In some embodiments, the base 100 is a plastic part.
[0062] Specifically, the base 100 is made of a PVC board, which has good insulation and will not cause the surface induction hardening sensor 2 to be grounded. It is simple to manufacture, easy to use, and highly portable.
[0063] In some embodiments, reference Figure 3 and Figure 4 The distance between the detection plane 200 in the middle of the substrate 100 and the bottom surface of the substrate 100 is the largest, and the distance between the detection plane 200 in the middle of the substrate 100 and the bottom surface of the substrate 100 decreases gradually toward both sides of the substrate 100 .
[0064] The distance between the detection plane 200 in the middle of the substrate 100 and the bottom surface of the substrate 100 is the largest, and decreases toward both sides, and the distances between several detection planes 200 and the bottom surface of the substrate 100 are different. At this time, the substrate 100 is set in the form of a boss. During use, a shorter substrate 100 can be extended, and the required detection plane 200 can be moved to the right below the corresponding sensor 2, which is beneficial when there is an obstacle next to the workpiece 1, that is, when the extension of the substrate 100 is limited, the measurement is performed through the shorter substrate 100 to facilitate the detection of the coupling gap.
[0065] Exemplarily, the distances between the detection planes 200 on both sides of the detection plane 200 in the middle of the substrate 100 and the bottom surface of the substrate 100 are staggeredly distributed on both sides of the detection plane 200 with the largest distance.
[0066] For example, refer to Figure 3 When the detection accuracy of the detection plane 200 is set to 0.1mm, the minimum distance from the detection plane 200 to the substrate 100 is 2mm, and a total of 11 steps are set, then the distance from the detection plane 200 to the bottom surface of the substrate 100 from one end toward the other end is 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm, 2.9mm, 2.7mm, 2.5mm, 2.3mm, and 2.1mm respectively.
[0067] Exemplarily, the maximum value of the distance between the detection plane 200 and the bottom surface of the substrate 100 on one side of the detection plane 200 in the middle of the substrate 100 may be smaller than the minimum value on the other side.
[0068] For example, refer to Figure 4When the detection accuracy of the detection plane 200 is set to 0.1mm, the minimum distance from the detection plane 200 to the substrate 100 is 2mm, and a total of 11 steps are set, then the distance from the detection plane 200 to the bottom surface of the substrate 100 from one end toward the other end is 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 3mm, 2.9mm, 2.8mm, 2.7mm, and 2.6mm respectively.
[0069] The coupling gap inspection device provided in the present application can quickly detect the coupling gap of the tool setting through the detection plane 200 set on the base 100, improve the tool setting accuracy, ensure the consistency of the coupling gap in each processing, and improve the stability of the surface induction quenching quality of the workpiece 1; at the same time, the coupling gap between the workpiece 1 and the surface induction quenching sensor 2 during tool setting can be quickly read through the mark, thereby reducing the calculation time and improving the efficiency; and the base 100 is a plastic part with good insulation, which will not cause the surface induction quenching sensor 2 to be grounded, and is simple to manufacture and easy to use.
