Description

Technical Field

[0001] The present application relates to the technical field of new energy vehicle parts processing and detection, and in particular to a processing and detection method and a detection device for a forged flange with a press-fitted steel ring. Background Art

[0002] New energy vehicles need to be equipped with shock absorbers to reduce body bumps and reduce the risk of damage to batteries and electronic components, thereby extending the service life of the vehicle. Figures 1 to 3 As shown, a mounting flange 100 of an air shock absorber in the related art is generally manufactured by a metal precision forging process because it needs to have a high strength. The flange 100 is provided with a first accommodating chamber 104 and a second accommodating chamber 111, which are connected through a central through hole 105. Because it is necessary to adapt to the shock absorber housing, the bottom surface of the flange 100 is an inclined surface, and the axes of the second accommodating chamber 111, the screw mounting hole 112 and the airway mounting hole 113 on the bottom surface are all perpendicular to the bottom surface. In addition, a steel ring accommodating groove 106 is also provided on the upper part of the flange 100 for accommodating the steel ring 101. Since the second accommodating chamber 111 and the steel ring 101 have an assembly relationship with external parts, the angle between the second accommodating chamber 111 and the axis of the steel ring 101 is an important dimension, and a high manufacturing accuracy needs to be maintained. Since the processing bases of the second accommodating chamber 111 and the steel ring accommodating groove 106 are inconsistent, processing deviation will occur. In the prior art, a relatively expensive profilometer is required to detect the angle between the second accommodating cavity 111 and the axis of the steel ring 101. The equipment is expensive and the detection efficiency is not high, making it difficult to perform batch or full inspection on products, which needs to be improved. Summary of the invention

[0003] In order to solve the technical problems in the prior art that the deviation between the second accommodating cavity of the flange and the axis of the steel ring is difficult to detect and the detection efficiency is low, the present invention provides a processing and detection method and detection device for a forged flange with a steel ring pressed on.

[0004] The technical solution provided by the present application is as follows: A processing and detection method for a forged flange with a press-fitted steel ring, comprising the following steps:

[0008] S4, using the bottom inclined surface of the flange as a processing reference, processing a second accommodating cavity, wherein the axis of the second accommodating cavity is perpendicular to the bottom inclined surface of the flange, and the first accommodating cavity and the second accommodating cavity are connected through a central through hole;

[0009] S5, pressing the steel ring into the steel ring receiving groove;

To ensure the accuracy and reliability of the detection, the flange must first be accurately installed on the detection device, and then the flange can be inspected with the help of visual inspection equipment. The present application provides a cylindrical inner cavity reference seat, the upper part of which is an elastic cylindrical chuck, the top of the elastic cylindrical chuck abuts against the top wall of the second accommodating cavity, and the outer wall of the elastic cylindrical chuck fits with the inner wall of the second accommodating cavity after the elastic cylindrical chuck expands, which can fix the flange very firmly.

DETAILED DESCRIPTION

[0048] The following is combined with Figures 1 to 18 This application is described in further detail.

[0049] Reference Figures 4 to 6 , is a schematic diagram of the final product of the first embodiment of the flange of the present application. The difference from the flange in the prior art is that a detection cutout 107 is processed on the outer side of the flange, and an X-direction vertical positioning groove 109 and a Y-direction vertical cutting edge 110 are processed on the bottom inclined surface 108 of the flange 100.

[0050] The processing and inspection method of the forged flange 100 with the steel ring 101 pressed thereon comprises the following steps:

[0051] S1, blanking, performing hot rough forging, hot fine forging and trimming operations on the original blank to obtain a blank;

[0052] S2, using the outer circle of the blank as the machining reference plane, machining the top plane 102 and the head structure of the flange 100, wherein the head structure at least includes a first outer circumferential surface 103, a first accommodating cavity 104, a central through hole 105 and a steel ring accommodating groove 106, wherein the outer inner wall of the steel ring accommodating groove 106 is perpendicular to the top plane 102; Figure 4 and Figure 5 As shown, a detection cutout 107 is synchronously processed on the outer side of the flange 100, and the detection cutout 107 includes an X-axis detection edge 1071, a Y-axis detection edge 1072 and a Z-axis detection plane 1073; Figure 4 and Figure 5 As shown, the X-axis detection edge 1071 is parallel to the design size of the top plane 102 of the steel ring 101; the Y-axis detection edge 1072 is parallel to the design size of the central axis of the steel ring 101; the Z-axis detection plane 1073 is parallel to the design size of the central axis of the steel ring 101;

[0053] S3, using the top plane 102 of the flange 100 as the horizontal machining reference plane, using the first outer circumferential surface 103 of the head structure as the transverse reference plane, machining the bottom inclined surface 108 of the flange 100, and synchronously machining the X-direction vertical positioning groove 109 and the Y-direction vertical cutting edge 110, as shown in FIG. Figure 6 As shown;

[0054] S4, using the bottom inclined surface 108 of the flange 100 as a processing reference, a second accommodating cavity 111 is processed, the axis of the second accommodating cavity 111 is perpendicular to the bottom inclined surface 108 of the flange 100, and the first accommodating cavity 104 and the second accommodating cavity 111 are connected through the central through hole 105. In this step, a screw mounting hole 112, an airway mounting hole 113 and an inclined airway 114 are also processed synchronously, the axes of the screw mounting hole 112 and the airway mounting hole 113 are perpendicular to the bottom inclined surface 108 of the flange 100, and the airway mounting hole 113 is connected to the steel ring accommodating groove 106 through the inclined airway 114;

[0055] S5, press the steel ring 101 into the steel ring receiving groove 106; then use the automatic screw locking machine to install the screw 115 in the screw mounting hole 112. Manual installation of each screw 115 takes two to three minutes, while the automatic screw locking machine can control it within one minute, and the installation efficiency is higher;

[0056] S6, set the cylindrical inner cavity reference seat 2, place the flange 100 on the cylindrical inner cavity reference seat 2, so that the inner wall of the second accommodating cavity 111 fits with the outer wall of the cylindrical inner cavity reference seat 2, and the top of the cylindrical inner cavity reference seat 2 abuts against the top wall of the second accommodating cavity 111, as shown in FIG. Fig.13 As shown;

[0057] S7, set the angle reference seat 3, so that the angle reference seat 3 is inserted into the X-direction vertical positioning groove 109 of the flange 100, as shown in FIG. Fig.11 As shown; the flange 100 can be at a fixed horizontal angle;

[0058] S8, set up an XY axis reference base 4, and set up an XY visual inspection device 6 on the XY axis reference base 4 to inspect the X axis detection edge 1071 and the Y axis detection edge 1072, such as Fig.10 As shown;

[0059] S9, set the Z-axis reference seat 5, set the Z-axis visual detection device 7 on the Z-axis reference seat 5 to detect the Z-axis detection plane 1073, such as Fig.10 shown.

[0060] The present application converts the detection of the deviation between the second accommodating cavity 111 of the flange 100 and the axis of the steel ring 101 into the detection of the surface contour. The size of the detection cutout 107 should be correlated and theoretically correspond to the size to be detected of the second accommodating cavity 111. Since the steel ring accommodating groove 106 and the detection cutout 107 are processed from the same reference, the processing accuracy mainly depends on the accuracy of the processing equipment. The accuracy of the processing equipment (CNC milling machine or machining center) in the prior art is already very high. Therefore, at this time, based on the processing reference of the steel ring accommodating groove 106, the size of the detection cutout 107 is basically consistent with the design size; when viewed from the processing reference of the second accommodating cavity 111, the size of the detection cutout 107 will deviate from the design size. This deviation is the processing deviation between the second accommodating cavity 111 and the axis of the steel ring 101, which needs to be controlled within a certain range. The present application utilizes the cylindrical inner cavity reference seat 2 and the X-axis vertical positioning groove 109 to completely fix the flange 100, so that the flange 100 is stably in the detection position, and then utilizes the XY visual inspection device 6 to inspect the X-axis detection edge 1071 and the Y-axis detection edge 1072, and utilizes the Z-axis visual inspection device 7 to inspect the Z-axis detection plane 1073. Since the inspection can be performed directly, there is no need to use a more expensive profilometer, and the inspection efficiency is also higher. The inspection results of the visual inspection equipment are objective and repeatable, avoiding the human factors in manual inspection, and have great advantages in inspection consistency, inspection accuracy and inspection efficiency. Batch inspection results can be stored for quality analysis and quality traceability.

[0061] like Figures 7 to 9As shown, the detection device for realizing the processing detection method of the forged flange 100 with the steel ring 101 pressed thereon comprises a mounting plate 1, a cylindrical inner cavity reference seat 2, an angle reference seat 3, an XY axis reference seat 4, a Z axis reference seat 5, an XY visual detection device 6, a Z axis visual detection device 7 and a pressing mechanism 8. The cylindrical inner cavity reference seat 2, the angle reference seat 3, the XY axis reference seat 4 and the Z axis reference seat 5 are all fixedly arranged on the mounting plate 1; the angle reference seat 3 is used to be engaged with the X-direction vertical positioning groove 109 of the flange 100, the XY visual detection device 6 is arranged on the XY axis reference seat 4, and the Z axis visual detection device 7 is arranged on the Z axis reference seat 5.

[0062] like Fig.14 As shown, the upper part of the cylindrical inner cavity reference seat 2 is an elastic cylindrical chuck 21, and the cylindrical inner cavity reference seat 2 is provided with a central axis hole 22; Fig.16 As shown, the pressing mechanism 8 is arranged on the mounting plate 1, and the pressing mechanism 8 includes a pressing power unit 81, a push rod 82 and a pressing plate 83. The pressing power unit 81 is arranged on the mounting plate 1, and the push rod 82 and the pressing plate 83 are both arranged on the pressing power unit 81. Fig.13 As shown, the pressing plate 83 is used to press the flange 100 onto the cylindrical inner cavity reference seat 2 so that the top of the cylindrical inner cavity reference seat 2 fits with the top wall of the second accommodating cavity 111; the top end of the push rod 82 is also provided with a conical head 821, which is used to open the elastic cylindrical chuck 21 so that the outer wall of the elastic cylindrical chuck 21 fits with the inner wall of the second accommodating cavity 111.

[0063] like Fig.14 As shown, the top of the central axis hole 22 of the cylindrical inner cavity reference seat 2 is provided with a chamfer 23, so as to facilitate the conical head 821 of the push rod 82 to be inserted into the central axis hole 22 more smoothly. Fig.16 As shown, the tail of the push rod conical head 821 is also provided with a cylindrical extension section 822 to prevent the conical head 821 from being worn out after multiple tests, thereby affecting the expansion scale of the elastic cylindrical chuck 21 and further affecting the positioning effect of the flange 100.

[0064] like Figure 8 As shown, the pressing power unit 81 of this embodiment is a quick clamp, which has a simple structure, is convenient for manual operation, has low cost, and is suitable for small and medium batch production. If it is a large batch of tens of thousands, a downward pressure cylinder can be used to reduce the workload of the operator.

[0065] At the production site of the flange 100, the deviation between the second accommodating cavity 111 of the flange 100 and the axis of the steel ring 101 is detected online by the detection device, so as to ensure the rapid judgment of the quality status of the flange 100 during trial production and initial production. To ensure the accuracy and reliability of the detection, the flange 100 needs to be accurately installed on the detection device first, and then the flange 100 can be detected with the help of visual inspection equipment. The present application sets a cylindrical inner cavity reference seat 2, the upper part of which is an elastic cylindrical chuck 21, the top of the elastic cylindrical chuck 21 abuts against the top wall of the second accommodating cavity 111, and the outer wall of the elastic cylindrical chuck 21 is in contact with the inner wall of the second accommodating cavity 111 after the expansion, which can fix the flange 100 very firmly. The angle reference seat 3 is used to locate the angle in the horizontal direction. The overall position accuracy of the flange 100 is extremely high, which can naturally improve the accuracy and reliability of the detection.

[0066] Reference Fig.17 and Fig.18 , is a schematic diagram of the final product of the flange embodiment 2 of the present application, which is different from the embodiment 1 in that a circle of stepped grooves 116 is provided on the outer edge of the bottom of the flange 100, and a circle of sealing ring 117 is formed by dispensing glue. The sealing ring 117 is made by a semi-open dispensing method. After the production is completed, the upper end and the side are protruding outward, which can not only play the role of end face sealing, but also play the role of side sealing if there are matching parts on the side.

[0067] If the sealing ring 117 is first made and then installed on the flange 100, the sealing ring 117 is large in size, difficult to process and difficult to install. If necessary, it must be glued to the flange 100, which is cumbersome, inefficient and costly. The present application directly uses glue to make the sealing ring 117, which is low in cost and does not require installation and pasting later.

[0068] Therefore, based on the processing and detection method in the first embodiment, step S3 also includes the step of processing a circle of stepped grooves 116 on the outer edge of the bottom of the flange 100; between steps S5 and S6, it also includes the step of using a glue dispenser to dispense glue in the stepped groove 116 to make a circle of sealing rings 117; and before dispensing glue, it also includes the step of using a laser to ablate the surface of the stepped groove 116 to increase the roughness of the surface of the stepped groove 116, thereby increasing the adhesion between the glue and the surface of the stepped groove 116 and reducing the risk of falling off and failure. In addition, the width and depth of the stepped groove 116 should be greater than 3mm, at least greater than 2mm, otherwise the overflow of glue is not easy to control, and there is a risk of substandard adhesion.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
