Description

Technical Field

[0001] The present application relates to the field of speed reducer shaft processing, and in particular to a speed reducer shaft processing method. Background Art

[0002] A reducer is a mechanical transmission device that is usually used to convert the output of a high-speed rotating motor into a low-speed, high-torque output to meet the needs of various industrial applications. The reducer shaft is an important component of the reducer. It is the shaft that connects the motor output shaft and the reducer input shaft. The main shaft converts the high-speed rotation of the motor into a low-speed, high-torque output through gear transmission or worm transmission.

[0003] The reducer shaft is usually made of high-strength alloy steel or stainless steel to ensure its strength and durability. Its main processing methods include the following steps: raw material preparation → turning → hole processing → heat treatment → precision processing → assembly, and during the entire processing process, strict quality control and inspection are required to ensure that the size and position accuracy of the reducer shaft meet the design requirements and have good performance and reliability.

[0004] In the actual processing of the reducer shaft, in order to improve the processing efficiency, it is generally necessary to increase the single turning amount while ensuring the turning quality during the turning process. However, in the adjustment of processing parameters or the actual turning processing parameter setting, technical personnel can only make empirical or inferential adjustments to the processing parameters based on experience or previous data, and the CNC lathe cannot perform effective data monitoring of the adjusted parameters during the processing process, which often causes irreversible processing damage to the shaft during the actual processing process, which not only reduces the processing quality of the shaft, but also increases the cost loss of shaft processing, which is not conducive to the continuous improvement and development of shaft processing methods. Summary of the invention

[0005] The purpose of this application is to solve the problem of how to monitor the dimensional changes of the shaft body during machining and reduce its machining damage after setting and adjusting the machining parameters. Compared with the prior art, a method for machining a reducer shaft body is provided. The machining method involves a margin monitor installed on a CNC lathe, and specifically includes the following steps:

[0006] S1. Raw material preparation, cutting the shaft raw material into appropriate length to obtain the main shaft blank;

[0007] S2. Turning: turning the spindle blank, and clamping the spindle blank with a three-jaw chuck of a CNC lathe;

[0008] S21. Make the allowance monitor cooperate with the spindle blank, and use the allowance monitor to monitor and process the data of the spindle blank turning during the CNC lathe processing;

[0009] S22. After the allowance monitor determines that the turning processing dimension data is qualified, only the CNC lathe is used to display the monitoring parameters, and the CNC lathe continues processing to obtain the turning spindle;

[0010] S23. After the margin monitor determines that the turning dimension data is within the controllable range, the control data is transmitted to the controller of the CNC lathe, so that it performs real-time data compensation for subsequent turning parameters, and uses the CNC lathe to display the control parameters, and the CNC lathe continues processing to obtain the turning spindle;

[0011] S24. After the margin monitor determines that the turning dimension data is unqualified, an alarm reminder is issued first, and the alarm data is transmitted to the controller of the CNC lathe, so that the controller controls the CNC lathe to stop, and the CNC lathe is also used to display the alarm data. The technician processes the spindle blank and changes the subsequent turning parameters, and continues to process the next spindle blank, and repeats step S21;

[0012] S3. Boring processing, using a horizontal CNC milling machine to bore the turning spindle, processing the matching holes and mounting holes on the turning spindle, and obtaining a pre-processed spindle;

[0013] S4. Heat treatment, using heat treatment equipment to heat treat the pre-treated spindle to obtain the spindle to be ground;

[0014] S5. Precision machining, using a grinding machine to perform multiple precision grinding on the spindle to be ground to obtain the reducer spindle;

[0015] S6. Assembly: Assemble the reducer main shaft in the assembly workshop, install bearings, shaft shoulders, bushings and other accessories on it to obtain the reducer shaft body.

[0016] Further, the residual quantity monitor includes a mounting frame installed on the upper side of the CNC lathe, a monitoring industrial control box connected to the controller signal of the CNC lathe is fixedly installed on the right end of the mounting frame, a monitoring support plate matched with the CNC lathe is arranged at the lower end of the mounting frame, a plurality of uniformly distributed elastic inclined blocks are fixedly connected to the front end of the monitoring support plate, a monitoring seat is fixedly connected to the lower end of the elastic inclined block, and a pre-pressure roller rotatably connected to the elastic inclined block is slidably arranged at the front end of the monitoring seat;

[0017] The monitoring industrial control box is equipped with a turning monitoring and control system connected to the controller signal of the CNC lathe.

[0018] Furthermore, the method for monitoring and processing by the residual monitor includes the following steps:

[0019] S211 parameter setting, before turning the spindle blank, the margin monitoring processing unit receives the turning parameters transmitted by the CNC lathe controller through the parameter setting unit, and sets the detection standard value range according to the turning parameters;

[0020] S212. Zero detection, the margin monitoring processing unit controls the monitoring support plate to continuously approach the spindle blank, so that the front end of the preload roller contacts the outer end surface of the spindle blank, forming a slight pressure, at this time the margin sensing unit transmits the data to the margin monitoring processing unit, the margin monitoring processing unit at this time the position of the preload roller is reset to zero;

[0021] S213. After the turning preloading is completed, the margin monitoring processing unit displays the margin according to the turning parameters, and then the monitoring support plate continues to move, so that the preloading roller continuously squeezes the spindle blank, and the margin sensing unit transmits the data to the margin monitoring processing unit, and determines that the operation stops after the preloading roller reaches the set preloading position;

[0022] S214. The material reduction is released, and then the CNC lathe starts the program to continuously turn the spindle blank. When each single turning is performed and completed, the material reduction effect generated by the turning amount continuously releases the squeezing effect on the preload roller, and then the pressure change input by the excess sensing unit is judged by the excess monitoring processing unit on the quality status of the single turning amount;

[0023] S215. Determination process, repeating steps S22 to S24 according to the determined data until all turning operations are completed;

[0024] S216. Turning is completed. After the turning action is completed, the turning spindle releases the squeezing effect on the pre-loaded roller to the maximum extent. The pressure data input by the residual sensing unit and the pressure data reset to zero in step S212 are detected and compared to determine the turning error and the dimensional accuracy of the turning spindle, and the data is transmitted to the controller of the CNC lathe through the monitoring feedback unit.

[0029] Furthermore, an induction long groove is provided at the front end of the monitoring seat, and tension grooves are provided at both ends of the left and right ends of the induction long groove. A support bar is fixedly connected to the rear inner wall of the tension groove, and a pre-stress roller located in front of the two support bars is rotatably connected, and the pre-stress roller is slidably matched with the induction long groove, and an accompanying pressure sleeve is embedded in the rear inner wall of the induction long groove, and the front end of the accompanying pressure sleeve is abutted against the pre-stress roller, and the left and right ends of the accompanying pressure sleeve are respectively fixedly connected to the corresponding support bars. The cooperation between the support bar and the pre-stress roller can effectively avoid the influence of the pre-stress roller on the processing of the spindle blank while realizing the detection of the dimensional accuracy of the spindle blank by the pre-stress roller, reduce the friction resistance generated during the detection process, and ensure the processing efficiency and processing accuracy.

[0030] Furthermore, the inner cavity of the accompanying pressure sleeve is filled with a retaining object, and a pressure sensing probe is fixedly connected to the rear inner wall of the inner cavity of the accompanying pressure sleeve. The input end of the residual sensing unit is connected to the signal of the pressure sensing probe. The accompanying pressure sleeve can effectively display and convert the position data of the pre-loaded roller by using the pressure sensing probe, thereby improving the detection response accuracy while reducing the difficulty of data conversion, improving the computing efficiency of the residual monitoring processing unit, and ensuring the accuracy and efficiency of data monitoring and processing.

[0031] Optionally, the output end of the residual monitoring processing unit is also connected to a supporting and holding unit, a tension holding cavity is opened in the supporting bar, and the front and rear inner walls of the tension holding cavity are fixedly connected to an electromagnetic block, and the output end of the supporting and holding unit is connected to the electromagnetic block signal.

[0032] Compared with the prior art, the advantages of this application are:

[0033] (1) The turning process is monitored by the allowance monitor, and coordinated with the processing process of the CNC lathe, so as to effectively realize the real-time monitoring and processing of the single turning amount and the spindle blank size data after the single turning is completed, effectively realize the maintenance and monitoring of the setting of the turning processing parameters, and effectively avoid the irreversible damage to the spindle blank caused by processing errors or parameter adjustment errors. It can not only effectively realize the real-time monitoring of the processing process and the accurate guarantee of the processing size of the spindle blank, but also effectively combine with the improvement of processing parameters to assist technical personnel in the improvement and implementation of parameters, while reducing the improvement cost, promoting the continuous improvement and development of the reducer shaft processing method, ensuring the steady improvement of the reducer shaft processing quality and processing efficiency, and improving the economic benefits of reducer shaft processing.

[0034] (2) The coordination between the allowance monitor and the turning monitoring and control system can effectively coordinate the monitoring data with the processing parameters of the CNC lathe. While achieving dimensional monitoring assurance, it can also adjust the processing parameters of the CNC lathe in a timely manner, reduce the cumulative errors caused by CNC lathe processing, and thus effectively improve the processing quality of the reducer shaft. It can also effectively assist technical personnel in improving the processing parameters, reduce the improvement cost, and promote the production efficiency and processing quality of the reducer shaft, which is beneficial to improving the economic benefits of reducer shaft processing.

[0035] (3) Through the setting of zero detection and turning pre-pressure methods, the turning parameters can be effectively sensed and detected by means of excess release, which not only improves the monitoring accuracy of the excess monitor, but also improves the comprehensiveness of the turning monitoring and control system in the turning process. It can respond quickly when turning abnormalities occur, reduce the turning damage rate and error data, reduce the cost loss of the reducer shaft, and improve its processing quality.

[0036] (4) The turning amount data judgment module can use the pressure data transmitted by a single pre-pressure roller to judge the change of turning amount in a single turning process. It can not only judge the accuracy of turning amount control in the early stage of turning to avoid overcutting or undercutting, but also count the wear of subsequent turning tools. It can assist the CNC lathe to make data compensation or stop the machine to change tools when the wear is large, effectively ensuring the processing quality of the reducer shaft.

[0037] (5) After a single-pass turning is completed, the cylindricity calculation module and the end face straightness calculation module can effectively use the same batch data fed back by multiple pre-loaded rollers to perform calculations and judgments to determine the cylindricity data and end face straightness data of the spindle blank after the single-pass turning is completed. This enables the monitoring data processing module to analyze the dimensional accuracy of the shaft blank at this time based on the combination of these two data, and can assist the CNC lathe in regulating the subsequent turning process based on the data, effectively ensuring the processing quality of the reducer shaft.

[0038] (6) The cooperation between the offset drive group and the offset control unit can not only increase the adaptability of the excess monitor to reducer shafts of different sizes and expand its scope of use, but also effectively realize the precise control and maintenance of the position of the preload roller, and effectively realize its pressure release data detection of the spindle blank. In addition, the cooperation between the position drive group and the position control unit can effectively realize the control of the detection position of the excess monitor, and can be suitable for reducer shafts with different installation positions and different appearance conditions, further increasing the scope of use of the excess monitor and improving its effect.

[0039] (7) The setting of the self-warning unit can display the abnormal position of the spindle blank after the CNC lathe is shut down urgently with the assistance of the margin monitor, effectively assisting the technicians to judge the status of the spindle blank. It can not only facilitate the subsequent repair and recycling of the spindle blank, but also assist in judging the problems caused by the processing process, improve the efficiency of technicians in solving problems, shorten downtime, and reduce economic losses.

[0040] (8) The setting of the support and holding unit effectively maintains the continuous effect of the preload roller, enabling it to be used repeatedly, avoiding elastic damage to the support strip caused by preload monitoring, and ensuring the monitoring effect of the residual monitor.

[0068] See also Figure 3 and Figure 4 The monitoring and processing method of the residual monitor 2 includes the following steps:

[0069] S211 parameter setting, before turning the spindle blank, the margin monitoring processing unit receives the turning parameters transmitted by the controller of the CNC lathe 1 through the parameter setting unit, and sets the detection standard value range according to the turning parameters;

[0070] S212. Zero detection, the remaining amount monitoring processing unit controls the monitoring support plate 4 to continuously approach the spindle blank, so that the front end of the preload roller 61 contacts the outer end surface of the spindle blank, forming a slight pressure, at this time the remaining amount sensing unit transmits the data to the remaining amount monitoring processing unit, the remaining amount monitoring processing unit resets the position of the preload roller 61 to zero, at this time the distance from the center axis of the spindle blank to the rear end of the accompanying pressure sleeve 63 is L1;

[0071] S213. After the turning pre-pressing and zeroing are completed, the margin monitoring processing unit displays the margin according to the turning parameters, and then the monitoring support plate 4 is continuously moved, so that the pre-pressing roller 61 continuously squeezes the spindle blank, and the margin sensing unit transmits the data to the margin monitoring processing unit, and determines to stop the operation after the pre-pressing roller 61 reaches the set pre-pressing position. At this time, the distance from the center axis of the spindle blank to the rear end of the accompanying pressure sleeve 63 is L2, and L2<L1, L1-L2=the total amount of turning of the spindle blank required by the CNC lathe 1 (that is, the radius difference between the turning spindle and the spindle blank);

[0072] S214. The material reduction is released, and then the CNC lathe 1 starts the program to continuously turn the spindle blank. When each single turning is performed and completed, the material reduction effect generated by the turning amount continuously releases the squeezing effect on the pre-pressure roller 61, and then the pressure change input by the residual sensing unit is judged by the residual monitoring processing unit on the quality state of the single turning amount. At this time, the distance from the center axis of the spindle blank to the rear end of the accompanying pressure sleeve 63 is L3, and L2<L3<L1, L3 is a variable value during the operation of the CNC lathe 1, and the difference of the single L3 change is = the turning amount of the spindle blank by the CNC lathe 1 in a single time;

[0073] S215. Determination process, repeating steps S22 to S24 according to the determined data until all turning operations are completed;

[0074] S216. Turning is completed. After the turning action is completed, the turning spindle releases the squeezing effect on the pre-stressed roller 61 to the maximum extent. The pressure data input by the excess sensing unit and the pressure data reset to zero in step S212 are detected and compared to judge the turning error and the dimensional accuracy of the turning spindle, and the data is transmitted to the controller of the CNC lathe 1 through the monitoring feedback unit.

[0075] See also Figure 5 and Figure 6 The margin monitoring processing unit includes a monitoring data processing module, which is also signal-connected to a turning amount data judgment module, a cylindricity calculation module and an end face straightness calculation module. The turning amount data judgment module can use the pressure data transmitted by a single pre-pressure roller 61 to judge the change in the turning amount in a single turning process. It can not only judge the accuracy of the turning amount control in the early stage of turning to avoid overcutting or insufficient cutting, but also can count the wear of the subsequent turning tool, which can assist the CNC lathe 1 to make data when the wear is large during turning. The function of compensation or shutdown for tool change can effectively ensure the processing quality of the reducer shaft; the cylindricity calculation module and the end face straightness calculation module can effectively use the same batch data fed back by multiple pre-loaded rollers 61 for calculation and judgment after the single-pass turning is completed, and judge the cylindricity data and end face straightness data of the spindle blank after the single-pass turning is completed, so that the monitoring data processing module can analyze the dimensional accuracy of the shaft blank at this time according to the combination of these two data, and can assist the CNC lathe 1 to regulate the subsequent turning process according to the data, effectively ensuring the processing quality of the reducer shaft.

[0076] See also Figure 6-10 A deflection drive group 23 is provided at the upper end of the mounting frame 21, and a long arm frame 3 located on the inner side of the mounting frame 21 is slidably provided on the deflection drive group 23. A position drive group 31 is provided at the upper end of the long arm frame 3, and a sliding sleeve block 32 is slidably connected to the position drive group 31. The lower end of the sliding sleeve block 32 extends to the lower side of the long arm frame 3 and is fixedly connected to the monitoring support plate 4.

[0077] See also Figure 5 and Figure 6 The output end of the residual monitoring processing unit is also connected to a position control unit and an offset control unit. The output end of the position control unit is connected to the position drive group 31 signal, and the output end of the offset control unit is connected to the offset drive group 23 signal. The cooperation of the offset drive group 23 and the offset control unit can not only increase the adaptability of the residual monitor 2 to reducer shafts of different sizes and increase its scope of use, but also effectively realize the precise control and maintenance of the position of the pre-loaded roller 61, and effectively realize its pressure release data detection of the spindle blank. In addition, the cooperation of the position drive group 31 and the position control unit effectively realizes the control of the detection position of the residual monitor 2, and can be suitable for reducer shafts with different installation positions and different appearance conditions, further increasing the scope of use of the residual monitor 2 and improving its effect.

[0078] It should be noted that the offset drive group 23 and the position drive group 31 are both relatively mature mechanical drive structures in the prior art. They can be set to a drive mode in which a motor, a screw and a screw sleeve cooperate, or can be set to a drive mode of an electric slide rail, or can be set to a drive mode of a cylinder, or other existing drive modes. The control of these drive modes is also prior art, so they will not be described in detail in this embodiment. Those skilled in the art can select and add auxiliary structures to them as needed.

[0079] See also Fig. 9 and Fig.10The front end of the monitoring seat 6 is provided with an inductive long groove, and tension grooves are provided at both ends of the inductive long groove. A support bar 62 is fixedly connected to the rear inner wall of the tension groove. The support bar 62 is made of elastic material, which can effectively maintain the elastic support for the pre-stress roller 61, and can drive the pre-stress roller 61 to automatically reset after the pressure is released. The pre-stress roller 61 located at the front side is rotatably connected between the two support bars 62, and the pre-stress roller 61 is slidably matched with the inductive long groove, and an accompanying pressure sleeve 63 is embedded in the rear inner wall of the inductive long groove. The front end of the accompanying pressure sleeve 63 abuts against the pre-stress roller 61, and the left and right ends of the accompanying pressure sleeve 63 are respectively fixedly connected to the corresponding support bar 62. The cooperation between the support bar 62 and the pre-stress roller 61 can effectively avoid the influence of the pre-stress roller 61 on the processing of the spindle blank while realizing the detection of the dimensional accuracy of the spindle blank by the pre-stress roller 61, reduce the friction resistance generated during the detection process, and ensure the processing efficiency and processing accuracy.

[0080] See also Fig. 9 and Fig.10 The inner cavity of the accompanying pressure sleeve 63 is filled with a retaining material, which is air, water or other liquid harmless substances. The retaining material maintains the filling saturation of the accompanying pressure sleeve 63 at 80%-95%, thereby assisting the support bar 62 to support and reset the preload roller 61, and also improving the sensing accuracy of the pressure sensing probe. The rear inner wall of the inner cavity of the accompanying pressure sleeve 63 is fixedly connected with a pressure sensing probe, and the input end of the residual sensing unit is connected to the pressure sensing probe signal. The accompanying pressure sleeve 63 uses the pressure sensing probe to effectively display and convert the position data of the preload roller 61, thereby improving the detection response accuracy while reducing the difficulty of data conversion, improving the calculation efficiency of the residual monitoring processing unit, and ensuring the accuracy and efficiency of data monitoring and processing.

[0081] Example 2

[0082] The present invention provides a method for processing a reducer shaft. The present invention provides a method for processing a reducer shaft, wherein the components identical or corresponding to those in Example 1 are marked with the corresponding reference numerals in Example 1. For the sake of simplicity, only the differences from Example 1 are described below. The difference between Example 2 and Example 1 is as follows: Figure 1-10 The output end of the residual monitoring processing unit is also connected to a supporting and holding unit. A tension holding cavity is opened in the supporting force bar 62. The front and rear inner walls of the tension holding cavity are fixedly connected with an electromagnetic block. The output end of the supporting and holding unit is connected to the electromagnetic block signal. The setting of the supporting and holding unit effectively maintains the continuous effect of the preload roller 61, so that it can be used repeatedly, avoiding elastic damage to the supporting force bar 62 caused by preload monitoring, and ensuring the monitoring effect of the residual monitor 2.

[0083] See also Figure 1-10, the winding directions of the two electromagnets are opposite. After the current in the same direction is passed, repelling magnetic poles will be generated, and then the residual monitoring processing unit can continuously input a stable amount of current to the electromagnetic block through the support and holding unit, so that a constant electromagnetic repulsion force is formed between the two electromagnetic blocks, thereby ensuring the constancy of the position of the pre-stress roller 61 in the induction long groove in the original state, and after the pre-stress roller 61 is subjected to the extrusion force between the monitoring support plate 4 and the spindle blank, it can react to the electromagnetic repulsion force. After the extrusion force continues to increase, the pre-stress roller 61 will move in the induction long groove, and the support bar 62 and the accompanying pressure sleeve 63 will produce a certain amount of contraction, so that the pressure data detected by the pressure sensing probe in the accompanying pressure sleeve 63, and due to the action of the support and holding unit, the stability of the driving force of the support bar 62 on the pre-stress roller 61 is effectively maintained, and after subsequent turning, the pre-stress roller 61 can be driven to move close to the end face of the spindle blank;

[0084] Then, after the outer end of the subsequent pre-load roller 61 is slightly worn, the pressure detection of the pressure sensing probe in the pressure sleeve 63 can effectively determine the amount of wear of the pre-load roller 61, and then the residual monitoring processing unit can increase the amount of current passing into the electromagnet through the supporting and retaining unit, thereby compensating for the wear of the pre-load roller 61, thereby extending the service life of the pre-load roller 61 and ensuring the monitoring accuracy of the residual monitor 2.

[0085] Example 3

[0086] The present invention provides a method for processing a reducer shaft, wherein the components identical or corresponding to those in Embodiment 1 are marked with the same reference numerals as those in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 are described below. Embodiment 3 is different from Embodiment 1 in that: Figure 1-10 The output end of the monitoring feedback unit is also connected to the self-warning unit, and the output end of the self-warning unit is respectively connected to the alarm lamp bead 51 signal arranged on the upper end of the elastic inclined block 5. The setting of the self-warning unit can display the abnormal position of the spindle blank after the residual monitor 2 assists the CNC lathe 1 to perform an emergency shutdown, and effectively assist the technicians to judge the state of the spindle blank, which can not only facilitate the subsequent rework and recycling of the spindle blank, but also assist in judging the problems generated in the processing process, improve the efficiency of technicians in solving problems, shorten the downtime, and reduce economic losses.

[0087] See also Figure 1-10When the turning dimension data is unqualified as recorded in step S24 in Example 1, the excess monitoring processing unit uses the monitoring feedback unit to not only transmit the unqualified parameters to the controller of the CNC lathe 1, so that the controller of the CNC lathe 1 controls the CNC lathe 1 to stop, but also controls the self-warning unit to start through the monitoring feedback unit, and starts the alarm lamp bead 51 at the upper end of the elastic inclined block 5 corresponding to the monitoring seat 6 of all unqualified transmission data positions, intuitively displays the unqualified position of the spindle blank, and facilitates the technicians to check and solve the problem.

[0088] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
