Description

Technical Field

[0001] The present invention relates to the field of vehicle transmission technology, and in particular to a transmission shaft processing method and device. Background Art

[0002] The drive shaft is an important component in the vehicle transmission system, which is used to transmit the power of the engine to the wheels to generate driving force. The drive shaft is mainly composed of a shaft body, a spline part, a mounting groove and other parts. The spline part and the retaining spring mounting groove can be processed at both ends of the shaft body to facilitate its connection with other parts and transmit the power of the engine. Because the spline part of the drive shaft is connected to other parts, this part requires a higher hardness. Therefore, after the shaft body is processed, the drive shaft must be heat treated to achieve a higher hardness. Because the structures at both ends of the drive shaft are different and the roles they play in the process of transmitting power are different, the hardness requirements at both ends are also different. Therefore, the heat treatment methods at both ends of the drive shaft are also different.

[0003] In order to ensure the correct heat treatment method at both ends of the transmission shaft, the direction of the transmission shaft before entering the heat treatment device must be correct. At present, the feeding direction of the transmission shaft is generally inspected manually before the transmission shaft enters the heat treatment device. Only after ensuring the direction is correct can the material enter the heat treatment device for heat treatment. However, manual inspection is prone to missed inspections. Summary of the invention

[0048] This embodiment discloses a method for processing a transmission shaft 04. Figure 1 , Figure 2 and Figure 3 As shown, it may include:

[0049] Step S11, the detection component 02 obtains a standard image of the transmission shaft 04; wherein the transmission shaft 04 includes a first spline portion 41, a connecting rod portion 42, and a second spline portion 43; the first spline portion 41, the connecting rod portion 42, and the second spline portion 43 are fixedly connected in sequence;

[0050] Step S12, based on the standard image, obtaining first standard data of the transmission shaft 04; wherein the first standard data includes a first ratio range, the first ratio range includes the ratio of the outer diameter of the first groove section 413 of the first spline portion 41 to the outer diameter of the second spline section 414 of the first spline portion 41; the first spline portion 41 includes a first spline section 412, a first groove section 413, and a second spline section 414; the first spline section 412, the first groove section 413, and the second spline section 414 are fixedly connected in sequence, and one end of the second spline section 414 away from the first groove section 413 is fixedly connected to the connecting rod portion 42;

[0051] Step S13, based on the start of the processing of the transmission shaft 04 processing device, the detection component 02 obtains a detection image of the transmission shaft 04 close to one end of the detection component 02;

[0052] Step S14, acquiring detection data of the transmission shaft 04 based on the detection image;

[0053] Step S15, based on the successful matching of the detection data with the first standard data, the transmission assembly 01 of the transmission shaft 04 processing device drives the transmission shaft 04 to enter the heat treatment assembly 03 for heat treatment.

[0054] In this embodiment, if Figure 2 As shown, the transmission shaft 04 processing device may include: a heat treatment component 03, a transmission component 01, and a detection component 02. The heat treatment component 03 is used to perform heat treatment on the transmission shaft 04 to obtain a higher hardness. The heat treatment component 03 may include a first heat treatment part 31 and a second heat treatment part 32. The first heat treatment part 31 and the second heat treatment part 32 may set different heat treatment conditions to meet the heat treatment requirements of different components. The transmission component 01 is used to transfer the transmission shaft 04 to the heat treatment component 03 for heat treatment, and transfer the transmission shaft 04 after the heat treatment to the next station. The detection component 02 can be arranged before the heat treatment component 03 to detect whether there is a problem of wrong material or reverse when the transmission shaft 04 enters the heat treatment component 03, so as to prevent damage to the transmission shaft 04. As shown Figure 3 As shown, the detection component 02 may include a collector 21 and a processor. The collector 21 may be disposed above the first spline portion 41 of the transmission shaft 04 to obtain images and data of the transmission shaft 04. The processor may be used to analyze and process the data collected by the collector 21.

[0055] like Figure 3 As shown, the transmission shaft 04 may include a first spline portion 41, a connecting rod portion 42, and a second spline portion 43. The first spline portion 41, the connecting rod portion 42, and the second spline portion 43 may be fixedly connected in sequence to transmit torque. Figure 4As shown, the first spline portion 41 may include a first spline segment 412, a first groove segment 413, and a second spline segment 414; the first spline segment 412, the first groove segment 413, and the second spline segment 414 may be fixedly connected in sequence. The end of the second spline segment 414 away from the first groove segment 413 may be fixedly connected to the connecting rod portion 42. The first groove segment 413 is used to install a retaining spring, which is used to clamp the sleeve connected to the spline to prevent it from falling off. Figure 5 As shown, the second spline portion 43 may include a second chamfered section 431, a first optical axis section 432, a second groove section 433, a second optical axis section 434, and a third spline section 435. The second chamfered section 431, the first optical axis section 432, the second groove section 433, the second optical axis section 434, and the third spline section 435 may be fixedly connected in sequence. One end of the third spline section 435 away from the second groove section 433 is fixedly connected to the connecting rod portion 42. The second groove section 433 is used to install a retaining spring to prevent the parts installed on the third spline section 435 from falling off. Since the retaining springs used in the first groove section 413 and the second groove section 433 are different, the groove depths thereof are also different.

[0056] like Figure 1 As shown, the method for processing the transmission shaft 04 may include steps S11 to S15, and the above steps will be described in detail below.

[0057] Step S11: In order to determine whether the transmission shaft 04 in the production process meets the standards, a database of standard transmission shafts 04 can be established, and a standard range of relevant parameters can be established. Figure 2 and Figure 3 As shown, in the early stage of trial production or mass production of the transmission shaft 04, a standard transmission shaft 04 with qualified quality is placed on the transmission assembly 01, and it is ensured that the first spline portion 41 is located on one side of the detection assembly 02. The detection assembly 02 obtains a standard image of the transmission shaft 04 through the collector 21. Standard images of multiple standard transmission shafts 04 can be collected, so that the number of images in the database is large, which is convenient for data analysis and processing.

[0058] Step S12, as Figure 4As shown, after collecting standard images of multiple standard transmission shafts 04, the first standard data can be obtained, which is used to compare the test data with the standard data during the production process to determine whether the test data meets the standard. The first standard data may include a first ratio range. In the trial production stage or the initial stage of mass production, the ratio of the outer diameter of the first groove section 413 of the first spline portion 41 of multiple standard transmission shafts 04 to the outer diameter of the second spline section 414 of the first spline portion 41 can be obtained first. Based on the multiple ratios obtained, the first ratio range is analyzed and calculated. In this way, in the actual mass production detection process, the ratio of the outer diameter of the first groove section 413 of the first spline portion 41 to the outer diameter of the second spline section 414 of the first spline portion 41 can be obtained first, and then compared with the first ratio range. If the detection value is within the first ratio range, it means that the test has passed and the transmission shaft 04 can enter the heat treatment component 03 for heat treatment; if the detection value exceeds the first ratio range, it means that the test has failed and the transmission shaft 04 cannot enter the heat treatment component 03 for heat treatment. It may be that the transmission shaft 04 is placed in the wrong direction or is a defective product and needs manual confirmation.

[0059] Step S13, after the database is established, when the transmission shaft 04 is mass-produced, the transmission shaft 04 processing device is started, and the transmission shaft 04 is transmitted to the bottom of the detection component 02 through the conveyor belt 12. The collector 21 of the detection component 02 collects the detection image of the transmission shaft 04 close to one end of the detection component 02 to obtain relevant data of the transmission shaft 04.

[0060] Step S14, after the collector 21 of the detection component 02 collects the detection image of the transmission shaft 04 close to one end of the detection component 02, the processor of the detection component 02 obtains the ratio of the outer diameter of the first groove section 413 of the first spline portion 41 of the transmission shaft 04 to the outer diameter of the second spline section 414 of the first spline portion 41, for comparison with the first ratio range.

[0061] Step S15, when the detection value is within the first ratio range, it means that the detection is passed, and the processor of the detection component 02 sends a signal to control the transmission component 01 of the transmission shaft 04 processing device to drive the transmission shaft 04 into the heat treatment component 03 for heat treatment.

[0062] In some embodiments, Figure 2 As shown, step S15 includes:

[0063] Step S151, based on the first standard data also including a first length range, matching the detection data with the first length range; wherein the first length range includes the length of the first spline segment 412;

[0064] Step S152, matching the detection data with the first ratio range based on the successful matching of the detection data with the first length range;

[0065] Step S153, based on the successful matching of the detection data with the first ratio range, the transmission assembly 01 of the transmission shaft 04 processing device drives the transmission shaft 04 to enter the heat treatment assembly 03 for heat treatment.

[0066] In this embodiment, if Figure 2 As shown, step S15 may include steps S151 to S153. The above steps may be described in detail below:

[0067] Step S151, the first standard data may further include a first length range. The first length range may be an allowable range of the length of the first spline segment 412. The processor obtains the length data of the first spline segment 412 through the detection image obtained by the detection component 02, and then compares it with the first length range.

[0068] Step S152, only by comparing the length of the first spline segment 412 with the first length range, determines whether the direction of the transmission shaft 04 is correct. The judgment condition is single, and there is a greater risk of misjudgment. The first ratio can be used as another judgment parameter. When the detection data of the first length is within the first length range, the detection data of the first ratio is compared with the first ratio range.

[0069] Step S153, when the detection data of the first ratio is also within the first ratio range, the transmission assembly 01 of the transmission shaft 04 processing device drives the transmission shaft 04 into the heat treatment assembly 03 for heat treatment. This can reduce the misjudgment rate of the detection assembly 02, thereby improving the yield rate of the transmission shaft 04 after heat treatment.

[0070] In some embodiments, Figure 4 As shown, step S152 includes:

[0071] Step S1521, based on the successful matching of the detection data with the first length range and the first standard data also including the second ratio range, matching the detection data with the second ratio range; wherein the second ratio range includes the ratio of the minimum diameter of the first chamfered section 411 to the outer diameter of the first spline section 412; wherein the first spline portion 41 also includes the first chamfered section 411; the first chamfered section 411 is fixedly connected to one end of the first spline section 412 away from the first groove section 413; the cross-sectional area of ​​the first chamfered section 411 gradually decreases from one end close to the first spline section 412 toward the other end;

[0072] Step S1522: Based on the successful matching of the detection data with the second ratio range, the detection data is matched with the first ratio range.

[0073] In this embodiment, in order to cooperate with the production of different transmission shafts 04, meet the detection of various transmission shafts 04, and further improve the misjudgment rate of the detection component 02, a second ratio and a second ratio range can be added for comparison, so as to more accurately determine whether the transmission shaft 04 is correct. The second ratio can be the ratio of the minimum diameter of the first chamfered section 411 to the outer diameter of the first spline section 412. Among them, the first spline portion 41 can also include a first chamfered section 411. The first chamfered section 411 is fixedly connected to one end of the first spline section 412 away from the first groove section 413; the cross-sectional area of ​​the first chamfered section 411 gradually decreases from one end close to the first spline section 412 to the other end. As shown in FIG. Figure 4 As shown, step S152 may include step S1521 and step S1522. The above steps may be described in detail below:

[0074] Step S1521, when the detection data of the first length is within the first length range, the detection data of the second ratio is compared with the second ratio range.

[0075] Step S1522: When the detection data of the second ratio is within the second ratio range, the detection data of the first ratio is compared with the first ratio range.

[0076] In some embodiments, Figure 4 As shown, step S152 also includes:

[0077] Step S1523, based on the detection data successfully matching the second ratio range and the first standard data also including the second length range, matching the detection data with the second length range; wherein the second length range is the length of the second spline segment 414;

[0078] Step S1524: Based on the successful matching of the detection data with the second length range, the detection data is matched with the first ratio range.

[0079] In this embodiment, if Figure 4 As shown, step S152 may further include step S1523 and step S1524, and the above steps may be described in detail below:

[0080] Step S1523: To further improve the detection accuracy, the length of the second spline segment 414 may be detected. When the detection component 02 determines that the second ratio data is within the second ratio range, the length of the second spline segment 414 is obtained and compared with the second length range.

[0081] Step S1524, when the detection data of the length of the second spline segment 414 is within the second length range, first ratio data is acquired, and the first ratio data is compared with the first ratio range.

[0082] In some embodiments, Figure 5 As shown, step S12 includes:

[0083] Step S121, based on the standard image, obtaining first standard data of the transmission shaft 04; wherein the first standard data includes a first initial ratio range; the first initial ratio range includes a ratio of an outer diameter of the first groove segment 413 of the first spline portion 41 to an outer diameter of the second spline segment 414 of the first spline portion 41;

[0084] Step S122, based on the standard image, obtaining second standard data of the transmission shaft 04; wherein the second standard data includes a third ratio range; the third ratio range includes the ratio of the outer diameter of the second groove segment 433 of the second spline portion 43 to the outer diameter of the third spline segment 435 of the second spline portion 43; the second spline portion 43 includes a first optical axis segment 432, a second groove segment 433, a second optical axis segment 434, and a third spline segment 435; the first optical axis segment 432, the second groove segment 433, the second optical axis segment 434, and the third spline segment 435 are fixedly connected in sequence, and one end of the third spline segment 435 away from the second groove segment 433 is fixedly connected to the connecting rod portion 42;

[0085] Step S123, based on the comparison between the first initial ratio range and the third ratio range, obtain the first ratio range and the first ratio warning range; wherein the first ratio range includes the range in the first initial ratio range that is greater than the set value with the third ratio range; the first ratio warning range includes the range in the first initial ratio range that is less than or equal to the set value with the third ratio range.

[0086] In this embodiment, if the first spline portion 41 and the second spline portion 43 of the transmission shaft 04 are close in size, it is not easy to detect when the transmission shaft 04 is placed in the reverse direction. In order to avoid this phenomenon, a first ratio range and a first ratio warning range can be set when establishing a database. Figure 5 As shown, step S12 may include steps S121 to S123, and the above steps may be described in detail below:

[0087] Step S121, when establishing a standard database, analyze and process the acquired standard image, and set a first initial ratio range (the first initial ratio range is an allowable range of the ratio of the outer diameter of the first groove segment 413 of the first spline portion 41 to the outer diameter of the second spline segment 414 of the first spline portion 41).

[0088] Step S122, when establishing a standard database, the third ratio range may be set as the second standard data, and the third ratio range may be an allowable range of the ratio of the outer diameter of the second groove section 433 of the second spline portion 43 to the outer diameter of the third spline section 435 of the second spline portion 43. Figure 5As shown, the second spline portion 43 may include a second chamfered section 431, a first optical axis section 432, a second groove section 433, a second optical axis section 434, and a third spline section 435. The second chamfered section 431, the first optical axis section 432, the second groove section 433, the second optical axis section 434, and the third spline section 435 may be fixedly connected in sequence. One end of the third spline section 435 away from the second groove section 433 is fixedly connected to the connecting rod portion 42.

[0089] Step S123, compare and analyze the first initial ratio range with the third ratio range, and obtain the first ratio range and the first ratio warning range. When the collected data is within the first ratio range, it can be accurately determined that the collected data is the data of the first spline part 41, indicating that the direction of the transmission shaft 04 is correct. When the collected data is within the first ratio warning range, the collected data may be the data of the first spline part 41, or the data of the second spline part 43, and it is not possible to accurately judge whether the direction of the transmission shaft 04 is correct. When the collected data is within the third ratio range, it can be accurately determined that the collected data is the data of the second spline part 43, indicating that the direction of the transmission shaft 04 is wrong. In order to achieve the above effect, the range between the minimum value of the first initial ratio range and the maximum value of the third ratio range can be divided into three parts, which are the first ratio range, the first ratio warning range and the third ratio range from small to large. When the collected data is within the first ratio warning range, the alarm of the detection component 02 issues an alarm to remind the operator to manually check the direction of the transmission shaft 04. After determining that the direction is correct, the next step can be carried out.

[0090] In some embodiments, the method for processing the transmission shaft 04 further includes:

[0091] Step S161, matching the detection data with the first ratio warning range based on the failure of matching the detection data with the first ratio range;

[0092] Step S162, based on the detection data successfully matching the first ratio warning range and the detection data successfully matching the first length range, the transmission assembly 01 of the transmission shaft 04 processing device drives the transmission shaft 04 to enter the heat treatment assembly 03 for heat treatment.

[0093] In this embodiment, the method for processing the transmission shaft 04 may further include step S161 and step S162, which are described in detail below:

[0094] Step S161: When the detection data detected by the detection component 02 is not within the first ratio range, the detection data is compared with the first ratio warning range.

[0095] Step S162, when it is determined that the detection data is within the first ratio warning range, the detection data is compared with the first length range, and when it is determined that the detection data is within the first length range, the transmission assembly 01 of the transmission shaft 04 processing device drives the transmission shaft 04 into the heat treatment assembly 03 for heat treatment. In this way, when the size of the first spline part 41 is close to the size of the second spline part 43, the first length range is used as the second parameter for comparison, which can reduce the misjudgment rate and thus improve production efficiency.

[0096] In some embodiments, the method for processing the transmission shaft 04 further includes:

[0097] Step S163, based on the successful matching of the detection data with the first ratio warning range, the successful matching of the detection data with the first length range and the successful matching of the detection data with the second ratio range of the first standard data, the transmission component 01 of the transmission shaft 04 processing device drives the transmission shaft 04 to enter the heat treatment component 03 for heat treatment; wherein, the second ratio range includes the ratio of the minimum diameter of the first chamfered section 411 to the outer diameter of the first spline section 412; wherein, the first spline portion 41 also includes a first chamfered section 411, and the first chamfered section 411 is fixedly connected to one end of the first spline section 412 away from the first groove section 413; the cross-sectional area of ​​the first chamfered section 411 gradually decreases from one end close to the first spline section 412 to the other end.

[0098] In this embodiment, the processing method of the transmission shaft 04 may further include step S163. In step S163, when the detection data is within the first ratio warning range and the detection data is also within the first length range, the second ratio may be detected. In this way, the three parameters are selected for comparison, so that the judgment of the detection component 02 is more accurate and the misjudgment rate is further reduced. The second ratio may be the ratio of the minimum diameter of the first chamfered section 411 to the outer diameter of the first spline section 412. Figure 4 As shown, the first spline portion 41 may further include a first chamfered section 411, and the first chamfered section 411 may be fixedly connected to one end of the first spline section 412 away from the first groove section 413; the cross-sectional area of ​​the first chamfered section 411 may gradually decrease from one end close to the first spline section 412 toward the other end. After determining that the detection data is within the second ratio range of the first standard data, the transmission assembly 01 of the transmission shaft 04 processing device drives the transmission shaft 04 into the heat treatment assembly 03 for heat treatment.

[0099] In some embodiments, the method for processing the transmission shaft 04 further includes:

[0100] Step S164, based on the failure of the detection data to match the first ratio warning range, a transmission shaft 04 error signal is issued.

[0101] In this embodiment, the processing method of the transmission shaft 04 may further include step S164. In step S164, when the detection data is not within the first ratio warning range, the detection component 02 sends a signal of an error in the transmission shaft 04 through the alarm and the display, reminding the operator to manually confirm and handle the abnormality. In this way, the risk of misjudgment can be reduced by manual reconfirmation.

[0102] In this embodiment, Figure 2 As shown, a transmission shaft 04 processing device is disclosed, comprising:

[0103] Transmission assembly 01, transmission assembly 01 includes a support unit 11, a conveyor belt 12, and a positioning plate 13; the support unit 11 is detachably connected to the conveyor belt 12, and the conveyor belt 12 drives the support unit 11 to move; the positioning plate 13 is arranged on one side of the moving direction of the support unit 11; the support unit 11 is used to support the shaft 04 to be driven;

[0104] The detection component 02 includes a collector 21; the collector 21 is arranged above the support unit 11 and is used to collect images of the transmission shaft 04;

[0105] The heat treatment component 03 is arranged at one end of the conveyor belt 12 and is used for heat treatment of the transmission shaft 04 .

[0106] In this embodiment, if Figure 2 As shown, the transmission shaft 04 processing device may include: a transmission component 01, a detection component 02 and a heat treatment component 03. The transmission component 01 may include a support unit 11, a conveyor belt 12, and a positioning plate 13. The support unit 11 may be detachably connected to the conveyor belt 12 to support the transmission shaft 04. The conveyor belt 12 may drive the support unit 11 to move. The positioning plate 13 may be arranged on one side of the movement direction of the support unit 11 to locate the position of the transmission shaft 04 to prevent inaccurate data collection. Figure 3 As shown, the detection component 02 may include a collector 21. The collector 21 may be disposed above the support unit 11, and is used to collect images of the transmission shaft 04. The detection component 02 may also include a support rod 22, a processor, a display, and an alarm. The support rod 22 is used to support the collector 21. The processor is used to process the data of the image collected by the collector 21, and compare it with the first standard data or the second standard data, and then send a signal of the comparison result to the display and the alarm. The display and the alarm display will display the comparison results to remind the operator to proceed to the next step. As shown in FIG. Figure 2 As shown, the heat treatment component 03 can be set at one end of the conveyor belt 12 to perform heat treatment on the transmission shaft 04 so that the transmission shaft 04 has a higher hardness.

[0107] In some embodiments, Figure 2 and Figure 3 As shown, the support unit 11 includes a first support 111 and a second support 112; the first support 111 and the second support 112 are spaced apart along the width direction of the conveyor belt 12; the first support 111 is closer to the detection component 02 than the second support 112, and the height of the support point of the first support 111 is greater than the height of the support point of the second support 112; the positioning plate 13 is arranged on the side of the second support 112 away from the first support 111; the collection plane of the collector 21 is parallel to the line connecting the support point of the first support 111 and the support point of the second support 112.

[0108] In this embodiment, if Figure 2 and Figure 3 As shown, the support unit 11 may include a first support 111 and a second support 112. The first support 111 and the second support 112 are arranged at intervals along the width direction of the conveyor belt 12. The first support 111 is closer to the detection component 02 than the second support 112, and the height of the support point of the first support 111 is greater than the height of the support point of the second support 112. In this way, the transmission shaft 04 can be close to the positioning plate 13 under the action of its own gravity to prevent the transmission shaft 04 from moving on the support unit 11, thereby making the detection more accurate. The positioning plate 13 can be set on the right side of the second support 112. When placing the transmission shaft 04, the end face of the second spline portion 43 of the transmission shaft 04 is placed against the positioning plate 13 to ensure that the position of the transmission shaft 04 is accurate. Because the height of the support point of the first support 111 is greater than the height of the support point of the second support 112, the collection plane of the collector 21 can be set to be parallel to the line connecting the support point of the first support 111 and the support point of the second support 112. In this way, the collected data can be more accurate.
