Description

Technical Field

[0001] The present invention relates to the field of bearing processing, and in particular to a processing method, system and terminal for the inner raceway of a cylindrical roller bearing. Background Art

[0002] A cylindrical roller bearing is composed of an inner ring and an outer ring with cylindrical rollers as rolling elements, and realizes low-friction transmission by the rolling of the rollers between the raceways. It mainly bears radial loads and is widely used in rolling bearings in industries, automobiles, railways and other fields.

[0003] Currently, when processing the inner ring of a bearing, its outer diameter is usually ground. In the grinding operation, a grinding wheel is usually used to reciprocate along the central axis direction of the inner ring to complete the grinding operation of the inner raceway.

[0004] When grinding by reciprocating the grinding wheel along the central axis direction of the bearing inner ring, since the middle part of the workpiece is ground for a longer time than the two sides, it is extremely easy for the middle part to appear sunken. Once such a depression appears, it is very difficult for the staff to detect it in time, which will cause the workpiece to be judged as unqualified due to not meeting the quality standards during subsequent finished product inspection, thereby reducing the yield rate of the bearing inner ring, and improvement is needed.

[0082] Step 100: Obtain a trigger signal of a preset processing machine tool.

[0083] The processing machine tool refers to a machine tool used for grinding the outer diameter of the inner ring of a cylindrical roller bearing. The trigger signal refers to a signal for knowing whether the processing machine tool is started. The trigger signal includes a standby signal and a start signal. The standby signal refers to a signal that the processing machine tool is not started. The start signal refers to a signal that the processing machine tool has been started. The standby signal and the start signal are both preset by those skilled in the art and will not be elaborated here. The trigger signal is obtained through a signal transceiver on the processing machine tool.

[0084] Step 101: When the trigger signal is consistent with the preset start signal, obtain workpiece model information.

[0085] The workpiece model information refers to the specific model of the inner ring of a cylindrical roller bearing that needs to be ground. It is obtained by scanning the barcode on the processing information sheet pasted in advance on the preset processing information area of the processing machine tool through a preset barcode scanner. The processing information area refers to the area for posting the processing information sheet. The processing information sheet refers to the information sheet for knowing the specific model of the inner ring of the cylindrical roller bearing being processed currently. The content obtained after the barcode scanner scans the barcode corresponds to the workpiece model information. Both the processing information area and the processing information sheet are set in advance by those skilled in the art and will not be elaborated here.

[0086] When the trigger signal is consistent with the start signal, it indicates that the processing machine tool has been started, and the workpiece model information needs to be obtained for subsequent steps.

[0087] Step 102: Determine the reference processing parameters and the reference detection route according to the workpiece model information.

[0088] The reference processing parameters refer to the feed rate and route when the grinding device grinds the workpiece being processed. The reference detection route refers to the route when the tolerance detection device performs tolerance detection on the workpiece being processed. The grinding device refers to the device used to grind the workpiece being processed. The tolerance detection device refers to the device used to perform tolerance detection on the workpiece being ground. The workpiece being processed in this embodiment refers to the inner ring of a cylindrical roller bearing.

[0089] Step 103: Control the preset grinding device to grind based on the reference processing parameters, and during grinding, control the preset tolerance detection device to perform tolerance detection along the detection route, and obtain the workpiece tolerance value of the preset workpiece being processed.

[0090] The workpiece tolerance value refers to the deviation value between the current size of the workpiece being ground and the preset reference size. The reference size is set in advance by those skilled in the art and will not be elaborated here. The workpiece tolerance value is obtained through the detection of the tolerance detection device.

[0092] The reference tolerance value refers to the maximum allowable deviation value between the actual size and the reference size of the workpiece being ground. The reference tolerance value is set in advance by those skilled in the art and will not be elaborated here. The adjustment method refers to the method used to perform grinding adjustment on the reference processing parameters of the grinding device. The adjustment method will be described in detail in subsequent steps 200 to 204 and will not be elaborated here.

[0093] When the tolerance value of the workpiece exceeds the reference tolerance value, it indicates that the tolerance of the machined workpiece is too large. It is necessary to control the grinding device to perform grinding adjustment by an adjustment method to complete the grinding of the machined workpiece.

[0094] Refer to Figure 2 , the adjustment method includes the following steps:

[0095] Step 200: When the tolerance value of the workpiece exceeds the preset reference tolerance value, obtain the abnormal tolerance position.

[0096] The abnormal tolerance position refers to the specific position on the machined workpiece where the tolerance is too large. When the tolerance detection device detects that the tolerance of the machined workpiece is too large, it will output the excessive position to the preset position terminal. Therefore, the abnormal tolerance position can be retrieved from the position terminal. The position terminal is used to store the specific position on the machined workpiece where the tolerance is too large. The position terminal is set by those skilled in the art in advance and will not be elaborated here.

[0097] When the tolerance value of the workpiece exceeds the reference tolerance value, it is necessary to obtain the abnormal tolerance position first for subsequent steps.

[0098] Step 201: Determine the tolerance difference value based on the workpiece tolerance value, the reference tolerance value, and the abnormal tolerance position.

[0099] The tolerance difference value refers to the difference between the tolerance of the current workpiece and the reference tolerance at different abnormal tolerance positions. Through the preset tolerance database, the tolerance difference value corresponding to the workpiece tolerance value, the reference tolerance value, and the abnormal tolerance position can be matched. It contains the corresponding relationship between the workpiece tolerance value, the reference tolerance value, the abnormal tolerance position, and the tolerance difference value. The tolerance database is a database set by humans and will not be elaborated here.

[0100] Step 202: Determine the feed rate adjustment parameter based on the tolerance difference value and the abnormal tolerance position.

[0101] The feed rate adjustment parameter refers to the value used to adjust the feed rate of the grinding device at different abnormal tolerance positions. Through the preset adjustment database, the feed rate adjustment parameter corresponding to the tolerance difference value and the abnormal tolerance position can be matched. It contains the corresponding relationship between the tolerance difference value, the abnormal tolerance position, and the feed rate adjustment parameter.

[0104] Step 204: Control the grinding device to perform grinding adjustment according to the adjusted post - processing parameters.

[0105] Control the grinding device to grind the workpiece to be processed with the adjusted post - processing parameters, thereby completing the grinding adjustment of the grinding device.

[0106] Refer to Figure 3 , the heating grinding method includes the following steps:

[0108] The workpiece conductivity value refers to the quantified value corresponding to the ability of the workpiece to be processed to conduct current. The reference workpiece size refers to the size that the workpiece to be processed should be in after the grinding process. Through the workpiece database, the workpiece conductivity value and the reference workpiece size corresponding to the workpiece model information can be matched, which includes the corresponding relationships among the workpiece model information, the workpiece conductivity value, and the reference workpiece size. The workpiece database is a manually set database and will not be elaborated here.

[0109] Step 301: Obtain the current workpiece size of the workpiece to be processed.

[0110] The current workpiece size refers to the size of the workpiece to be processed during the current grinding process. The current workpiece size of the workpiece to be processed can be measured by a tolerance detection device. A size sensor for detecting the size of the workpiece to be processed is set on the tolerance detection device.

[0111] Step 302: Determine the remaining machining size according to the current workpiece size and the reference workpiece size.

[0112] The remaining machining size refers to the size that the workpiece to be processed still needs to be ground. The remaining machining size can be obtained by calculating the difference between the current workpiece size and the reference workpiece size.

[0113] Step 303: Determine the heating range and the heating temperature value according to the remaining machining size, the workpiece model information, and the adjusted post - processing parameters.

[0114] The heating range refers to the size of the range within which the workpiece is heated to facilitate the adjustment of the feed rate. The heating temperature value refers to the temperature to which the workpiece is heated to facilitate the adjustment of the feed rate. Through a preset heating database, the heating range and heating temperature value corresponding to the remaining machining size, workpiece model information, and adjusted machining parameters can be matched. It contains the corresponding relationship between the remaining machining size, workpiece model information, adjusted machining parameters, heating range, and heating temperature value. The heating database is a manually set database and will not be elaborated here.

[0115] Step 304: Determine the required current value based on the heating temperature value.

[0116] The required current value refers to the current value required to heat the workpiece to the set heating temperature by using the method of electrically heating the workpiece. Through a preset current database, the required current value corresponding to the heating temperature value can be matched. It contains the corresponding relationship between the heating temperature value and the required current value. The current database is a manually set database and will not be elaborated here.

[0117] Step 305: Determine the electric shock position based on the workpiece model information and the heating range.

[0118] The electric shock position refers to the position where the electric heating device performs electric shock heating on the workpiece. The electric heating device refers to the device used to perform electric shock heating on the workpiece. Through a preset electric shock database, the electric shock position corresponding to the workpiece model information and the heating range can be matched. It contains the corresponding relationship between the workpiece model information, the heating range, and the electric shock position. The electric shock database is a manually set database and will not be elaborated here.

[0119] Step 306: Determine the current intensity value based on the required current value, the electric shock position, and the workpiece conductivity value.

[0120] The current intensity value refers to the intensity value of the current when the electric heating device performs electric shock heating on the workpiece. Through the current database, the current intensity value corresponding to the required current value, the electric shock position, and the workpiece conductivity value can be matched. It contains the corresponding relationship between the required current value, the electric shock position, the workpiece conductivity value, and the current intensity value.

[0121] Step 307: Determine the post-heating machining parameters based on the heating temperature value and the adjusted machining parameters.

[0122] The post-heating machining parameters refer to the parameters after the feed rate is further adjusted after the workpiece is heated. Through the adjustment database, the post-heating machining parameters corresponding to the heating temperature value and the adjusted machining parameters can be matched. It contains the corresponding relationship between the heating temperature value, the adjusted machining parameters, and the post-heating machining parameters.

[0123] Step 308: Based on the electric shock position, control a preset electric heating device to perform electric shock heating on the workpiece to be processed at a current intensity value, and after the electric shock heating, control the grinding device to perform grinding with the post-heating processing parameters.

[0124] Control the electric heating device to perform an electric shock on the electric shock position on the workpiece to be processed at a current intensity value, thereby heating the workpiece to be processed, and after the electric shock heating, control the grinding device to perform grinding with the post-heating processing parameters.

[0125] Refer to Figure 4 , the heating correction method includes the following steps:

[0126] Step 400: Match the reference current value from a preset current database according to the workpiece model information.

[0127] The reference current value refers to the maximum current value that the workpiece can withstand without affecting its own structural strength. Through the current database, the reference current value corresponding to the workpiece model information can be matched, which contains the correspondence between the workpiece model information and the reference current value.

[0128] Step 401: When the current intensity value exceeds the reference current value, determine the heating influence parameter based on the reference current value and the electric shock position.

[0129] The heating influence parameter refers to the range where the workpiece is affected by heating and the temperature value that can be reached when the electric heating device performs an electric shock on the electric shock position on the workpiece at the reference current value. Through the heating database, the heating influence parameter corresponding to the reference current value and the electric shock position can be matched, which contains the correspondence between the reference current value, the electric shock position, and the heating influence parameter. When the current intensity value exceeds the reference current value, it means that performing an electric shock on the workpiece at the current intensity value will affect the structural strength of the workpiece, and the heating influence parameter needs to be matched for subsequent steps.

[0130] Step 402: Determine the heating difference situation based on the heating influence parameter, the heating range, and the heating temperature value.

[0131] The heating difference situation refers to the difference in the heating range and temperature value of the workpiece when the electric heating device heats the workpiece at the reference current and the current intensity value respectively. Through the heating database, the heating difference situation corresponding to the heating influence parameter, the heating range, and the heating temperature value can be matched, which contains the correspondence between the heating influence parameter, the heating range, the heating temperature value, and the heating difference situation.

[0132] Step 403: Determine the correction position and the correction current value based on the heating difference situation, the reference current value, and the electric shock position.

[0133] The corrected position refers to the position after correcting the electric shock position. The corrected current value refers to the intensity value after correcting the current intensity value. Since the current intensity of the corrected current value is too low, it is impossible to achieve the required heating range and heating temperature value only by a single electric shock position. Therefore, it is necessary to perform electric shocks at multiple positions simultaneously, which indicates that there are multiple corrected positions. Through the electric shock database, the heating difference situation, the reference current value, and the corrected positions and corrected current values corresponding to the electric shock positions can be matched, which includes the corresponding relationships among the heating difference situation, the reference current value, the electric shock position, the corrected position, and the corrected current value.

[0134] Step 404: Based on the corrected position, control the electric heating device to perform electric shock heating on the workpiece to be processed with the corrected current value.

[0135] Control the electric heating device to perform electric shock heating on the corrected position on the workpiece to be processed with the corrected current value for grinding.

[0142] Step 502: Obtain the liquid type information of the conductive liquid.

[0143] The liquid model information refers to the specific model for the conductive liquid, which includes the conductivity coefficient of the conductive liquid. The liquid model information of the conductive liquid can be obtained by scanning the QR code on the container filled with the conductive liquid through a preset scanner. The content obtained after the scanner scans the QR code corresponds to the liquid model information.

[0144] Step 503: Determine the liquid current intensity value based on the current intensity value, the coverage thickness value, and the liquid model information.

Through the adhesion database, the liquid splash value corresponding to the liquid model information and the machine tool processing parameters can be matched, which includes the corresponding relationship between the liquid model information, the machine tool processing parameters, and the liquid splash value.

Through the adhesion database, the remaining liquid amount corresponding to the liquid adhesion value, the liquid splash value, and the spraying parameters can be matched, which includes the corresponding relationship between the liquid adhesion value, the liquid splash value, the spraying parameters, and the remaining liquid amount.

[0159] Step 603: Determine the actual liquid thickness value according to the remaining liquid amount and the current workpiece size.

[0160] The actual liquid thickness value is the thickness value actually reached by the conductive liquid on the workpiece after the conductive liquid splashes.

[0161] Step 604: Determine the spraying correction parameter according to the actual liquid thickness value, the covering thickness value, and the spraying parameters.

[0162] The spraying correction parameters refer to the situation where the liquid conductive liquid splashes due to the rotation of the workpiece, resulting in the actual thickness value of the liquid not reaching the required thickness value. Therefore, the spraying device needs to be corrected. The spraying correction parameters are the spraying dosage, moving speed, and moving route after correction. Through the spraying database, the spraying correction parameters corresponding to the actual liquid thickness value, covering thickness value, and spraying parameters can be matched, which includes the corresponding relationships among the actual liquid thickness value, covering thickness value, spraying parameters, and spraying correction parameters.

[0165] Refer to Figure 7 , the liquid reflux method includes the following steps:

[0167] The liquid splash amount refers to the amount of conductive liquid splashed out due to the rotation of the workpiece. The splash angle value refers to the angle value of the liquid splash when the conductive liquid splashes due to the rotation of the workpiece.

[0168] Step 701: Determine the splash speed value according to the liquid splash amount and machine tool processing parameters.

[0169] The splash speed value refers to the numerical value of the speed when the conductive liquid splashes out during the rotation of the workpiece. Through the preset splash database, the splash speed value corresponding to the liquid splash amount and machine tool processing parameters can be matched, which includes the corresponding relationships among the liquid splash amount, machine tool processing parameters, and splash speed value. The splash database is a database set by humans and will not be elaborated here.

[0170] Step 702: Determine the reflux angle value according to the splash angle value.

[0171] The reflux angle value refers to the angle value that the reflux device should present when the reflux device re-transports the splashed liquid back onto the workpiece. Through the preset reflux database, the reflux angle value corresponding to the splash angle value can be matched, which includes the corresponding relationship between the splash angle value and the reflux angle value. The reflux database is a database set by humans and will not be elaborated here. The reflux device refers to the device used to re-transport the conductive liquid thrown out by the rotating workpiece back onto the workpiece.

[0172] Step 703: Determine the reflux adhesion value according to the liquid type information and the preset reflux type information.

[0173] The reflux model information refers to the model of the reflux device, which includes the material of the reflux device. The reflux model information is preset by those skilled in the art and will not be elaborated here. The reflux adhesion value is a quantitative value corresponding to the degree to which the conductive liquid adheres to the reflux device. Through the adhesion database, the reflux adhesion value corresponding to the liquid model information and the reflux model information can be matched, which includes the corresponding relationship among the liquid model information, the reflux model information, and the reflux adhesion value.

[0174] Step 704: Determine the blowing force value and the blowing angle value according to the splash speed value, the reflux angle value, the reflux adhesion value, and the preset reflux distance value.

[0175] The reflux distance value refers to the distance value between the reflux device and the workpiece. The reflux distance value is preset by those skilled in the art and will not be elaborated here. The blowing angle value refers to the angle value of the blowing when the blowing device assists in transporting the conductive liquid on the reflux device. The blowing force value refers to the force value of the blowing when the blowing device assists in transporting the conductive liquid on the reflux device. The blowing device refers to the device used to assist in transporting the conductive liquid on the reflux device. Through the preset blowing database, the blowing force value and the blowing angle value corresponding to the splash speed value, the reflux angle value, the reflux adhesion value, and the reflux distance value can be matched, which includes the corresponding relationship among the splash speed value, the reflux angle value, the reflux adhesion value, the reflux distance value, the blowing force value, and the blowing angle value. The blowing database is a manually set database and will not be elaborated here.

[0176] Step 705: Determine the liquid return flow according to the blowing force value, the blowing angle value, the reflux adhesion value, and the liquid splash amount.

[0177] The liquid return flow refers to the amount of liquid that the workpiece can actually receive when the conductive liquid is re-transported back to the workpiece by the reflux device. The liquid return flow can be calculated through the algorithm formula Q = S * (A + k1 * F * C) * (1 - e （-k2*F） )), where Q is the liquid return flow, S is the liquid splash amount, A is the reflux adhesion value, F is the blowing force value, C is the blowing angle value, 1 - e （-k2*F） is the correction factor for the influence of the blowing force value on the liquid return flow, and k1 and k2 are constants. 1 - e （-k2*F） , k1, and k2 are all calculated in advance by those skilled in the art and will not be elaborated here.

[0178] Step 706: Determine the reflux spraying parameter according to the liquid return flow, the covering thickness value, and the spraying correction parameter.

[0179] The reflux spraying parameters refer to the fact that since the conductive liquid can be re - transported back by the reflux device for a certain amount of liquid, it is necessary to correct the dosage, moving speed, and moving route of the spraying device when spraying the conductive liquid again. The reflux spraying parameters are the spraying correction parameters after the second correction. Through the spraying database, the liquid return flow rate, coverage thickness value, and the corresponding reflux spraying parameters of the spraying correction parameters can be matched, which includes the corresponding relationships among the liquid return flow rate, coverage thickness value, spraying correction parameters, and reflux spraying parameters.

And while the blowing device is blowing, control the spraying device to spray the conductive liquid onto the workpiece with the reflux spraying parameters for subsequent electric heating.
