[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figures 1 to 9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0035] The embodiment of the present application discloses a shaft processing device, which includes: a feeding module 1 , a manipulator 2 and a processing module 3 . The processing module 3 includes a limit plate 31 , a fixture 32 and a processing assembly 33 .
[0036] The loading module 1 is used to transport the shaft workpiece 4 to the material taking area 11 , so that the manipulator 2 can clamp the shaft workpiece 4 in the material taking area 11 .
[0037] The manipulator 2 is used to transfer the shaft workpiece 4 in the material taking area 11 to the processing module 3. Optionally, the manipulator 2 is used in conjunction with a guide rail, and the first end of the manipulator 2 is connected to the guide rail so that the manipulator 2 can slide on the guide rail.
[0038] The processing module 3 is used to process the shaft workpiece 4. Among them, the limit plate 31 is used to limit the position of the shaft workpiece 4 entering the fixture 32. The fixture 32 is used to clamp the shaft workpiece 4. The processing assembly 33 is used to process the shaft workpiece 4. Optionally, a through hole is provided on the limit plate 31, the size of the through hole matches the size of the shaft workpiece 4, and the through hole is aligned with the fixture 32. The manipulator 2 clamps and transfers the shaft workpiece 4, passes the shaft workpiece 4 through the through hole, and sends it into the fixture 32. After the fixture 32 clamps the shaft workpiece 4, the processing assembly 33 is used to process the shaft workpiece 4.
[0039] Furthermore, a guide rail is provided at the bottom of the processing assembly 33 to control the processing assembly 33 to move in any direction. Similarly, a guide rail is also provided at the bottom of the limiting plate 31 to control the limiting plate 31 to move in any direction.
[0040] The present application embodiment discloses a shaft processing method. Figure 2 , the method comprising: Step S201: transport the shaft workpiece to the material removal area through the loading module.
[0041] The material picking area is the area in the shaft processing equipment where the manipulator clamps the unprocessed shaft workpiece. Figure 1 The illustrated embodiments will not be described in detail here.
[0042] Step S202: Control the manipulator to clamp the shaft workpiece and transport the shaft workpiece to the processing module. The processing module includes a limit plate, a fixture and a processing component. The limit plate is provided with a through hole, the through hole is aligned with the fixture, and a push rod is provided inside the fixture.
[0043] The first end of the manipulator is connected to the guide rail so that the manipulator can slide on the guide rail. Exemplarily, after the manipulator clamps the shaft workpiece, the manipulator is controlled to slide on the guide rail to transfer the shaft workpiece from the material picking area to the processing module.
[0044] The size of the through hole matches the size of the shaft workpiece, so that the shaft workpiece can pass through the through hole in the axial direction, so that the fixture can clamp the shaft workpiece.
[0045] Step S203: Control the manipulator to move the shaft workpiece so that the shaft workpiece enters the fixture through the through hole.
[0046] For example, when the manipulator is clamping a shaft workpiece, the shaft workpiece is controlled to align with the through hole, and the manipulator is controlled to move toward the through hole so that the shaft workpiece passes through the through hole and enters the fixture, so that the shaft workpiece can be clamped by the fixture for processing.
[0047] In some embodiments, the robot moves according to a preset program.
[0048] In some embodiments, a camera is used to obtain a scene image, the scene image at least including a manipulator and a limit plate, and the relative position of the manipulator and the limit plate is identified through the scene image. The manipulator is controlled to move the shaft workpiece according to the relative position.
[0049] Step S204: Clamp the fixture and use the processing assembly to process the shaft workpiece.
[0050] Exemplarily, after the fixture is clamped, the fixture is controlled to rotate along the axial direction, thereby driving the shaft workpiece to rotate along the axial direction. The shaft workpiece is processed using a processing assembly to process a preset shape on the side wall of the shaft workpiece.
[0051] Optionally, the processing component is a processing tool. When the processing component is used to process the shaft workpiece, the processing tool used can be adjusted according to actual needs.
[0052] Step S205: After the machining of the shaft workpiece is completed, the fixture is released, and a push rod is used to push the shaft workpiece out of the fixture.
[0053] Optionally, the push rod is a spring push rod. When the clamp is released, the spring push rod uses elastic deformation to push the shaft workpiece out of the clamp so that the robot can put in the next shaft workpiece.
[0054] In some other embodiments, the push rod may also be a mechanical push rod or a hydraulic push rod. The shaft processing equipment may adjust the position of the push rod.
[0055] By adopting the above technical solution, a robot is used to transfer the shaft workpiece to the fixture to realize automatic processing of the shaft workpiece. The entire processing process can be completed without human intervention, which can effectively improve the processing efficiency of the shaft workpiece.
[0056] In the following embodiments, when placing the shaft workpiece into the fixture, the length of the shaft workpiece exposed from the fixture needs to be considered, so as to ensure that the processing module can accurately process the shaft workpiece during the processing of the shaft workpiece. Therefore, the embodiment of the present application discloses a correction method for shaft processing. Figure 3 , the method comprising: Step S301: After tightening the clamp, measure the exposed length of the shaft workpiece out of the clamp.
[0057] In some embodiments, a live image is acquired by a camera, a fixture and a shaft workpiece clamped by the fixture are identified in the live image, and the exposed length of the shaft workpiece exposed from the fixture is read from the live image.
[0058] In some embodiments, a distance sensor is provided on the push rod, and the distance sensor is used to record the position of the push rod. When the shaft workpiece is clamped by the fixture, one end of the push rod abuts against the shaft workpiece, so the length of the push rod in the fixture is determined by the reading of the distance sensor, and then the exposed length of the shaft workpiece out of the fixture is determined.
[0059] In some embodiments, an infrared sensor is installed on the shaft processing device, and the infrared sensor can measure the distance from the infrared sensor to the fixture. When the fixture holds a shaft workpiece, the reading of the infrared sensor will change, thereby obtaining the exposed length of the shaft workpiece out of the fixture.
[0060] Step S302: Calculate the difference between the exposed length and the preset length to obtain the length difference.
[0061] The preset length is a preset empirical value, which is related to the processing method of the shaft workpiece. Relevant personnel can adjust the preset length value according to actual needs.
[0062] Step S303: When the length difference is greater than a first length difference threshold and less than a second length difference threshold, the length difference is used to correct the processing method of the processing component, and the first length difference threshold is less than the second length difference threshold.
[0063] The first length difference threshold and the second length difference threshold are both preset empirical values, and relevant personnel can adjust the values of the first length difference threshold and the second length difference threshold according to actual needs.
[0064] When the length difference is greater than the first length difference threshold and less than the second length difference threshold, it means that although the shaft workpiece clamped by the fixture does not meet the preset processing standard, it is still within the error range. The processing quality of the shaft workpiece can be ensured by correcting the processing method.
[0065] Exemplarily, if the processing method is controlled by a computer program, the origin of the reference system used by the computer program is adjusted according to the length difference. For example, the computer program includes a first instruction, and the first instruction indicates that the processing component is moved to the position of coordinates (4, 5), and the origin of the coordinate system is corrected using the length difference.
[0066] By adopting the above technical solution, when the exposed length of the shaft workpiece deviates greatly from the preset length, the length difference will be used to correct the processing method to ensure that the processed shaft workpiece meets the design standards.
[0067] In the following embodiments, when the length difference is greater than the second difference threshold, it is difficult to compensate for the effect of the exposed length by correcting the processing method, and direct processing will result in serious deficiencies in the processing quality of shaft workpieces. To solve the aforementioned problem, the embodiment of the present application discloses a method for adjusting the exposed length. Figure 4 , the method comprising: Step S401: when the length difference is greater than the second difference threshold, move the limit plate so that the entity part on the limit plate is aligned with the fixture.
[0068] The solid part refers to the area on the limit plate where no through holes are set.
[0069] When placing the shaft workpiece into the processing module, the shaft workpiece needs to pass through the through hole on the limit plate. In this step, the position of the limit plate needs to be adjusted so that the solid part on the limit plate is aligned with the fixture.
[0070] In some embodiments, according to a preset program, the limit plate is moved in a preset direction and a preset distance so that the solid part on the limit plate is aligned with the fixture.
[0071] In some embodiments, the position of the through hole on the limiting plate is obtained, and the position of the limiting plate is adjusted according to the position of the through hole so that the through hole on the limiting plate is not aligned with the fixture.
[0072] Step S402: adjusting the distance from the limiting plate to the fixture to a preset distance, where the preset distance is smaller than a preset length.
[0073] Optionally, the current position of the limit plate is obtained, and the current position includes the distance from the limit plate to the fixture. According to the current position and the preset distance, a moving mode of the limit plate is generated. The limit plate is moved by the moving mode so that the distance from the limit plate to the fixture is adjusted to the preset distance.
[0074] For example, if the preset length is 20 mm, the preset distance can be set to 25 mm. Relevant personnel can adjust the specific value of the preset distance according to actual needs.
[0075] Step S403: Loosen the clamp to allow the shaft workpiece to rest against the solid part.
[0076] If the push rod in the fixture is a spring push rod, and the distance from the limit plate to the fixture is a preset distance, after the fixture is released, the push rod will automatically push the shaft workpiece out so that the shaft workpiece is against the solid part.
[0077] If the push rod in the fixture is a mechanical push rod or a hydraulic push rod, and the distance from the limit plate to the fixture is a preset distance, after releasing the fixture, the push rod needs to be controlled to push the shaft workpiece out until the shaft workpiece abuts against the solid part and stops pushing the shaft workpiece out.
[0078] Step S404: Control the limit plate to move away from the fixture until the distance from the limit plate to the fixture becomes a preset length.
[0079] Since the shaft workpiece rests on the solid part, the limit plate is controlled to move away from the fixture until the distance from the limit plate to the fixture becomes a preset length. The exposed length of the shaft workpiece out of the fixture is also adjusted to the preset length, thereby ensuring that the exposed length of the shaft workpiece is reasonable.
[0080] Step S405: Clamp the fixture.
[0081] After clamping the fixture, the shaft workpiece is processed according to the preset length.
[0082] By adopting the above technical solution, the limit plate can be used to adjust the length of the shaft workpiece exposed from the fixture, so that the aforementioned length meets the design requirements, so that the processing of the shaft workpiece meets the design requirements. This is conducive to standardizing the size of the shaft workpiece and improving the processing accuracy.
[0083] In the following embodiment, when the shaft processing equipment is processing the shaft workpiece, processing debris will splash, and when the shaft workpiece is pressed against the solid part of the limit plate, if there is processing debris between the shaft workpiece and the limit plate, the processing debris will affect the exposed length of the shaft workpiece and also cause damage to the shaft workpiece and the limit plate. For this reason, the embodiment of the present application discloses a method for using the limit plate. Figure 5 , the method comprising: Step S501: When the shaft workpiece abuts against the solid part, move the limit plate in the vertical direction.
[0084] Optionally, in the case where the push rod is a spring push rod, after the clamp is released, after a preset period of time, it is determined that the push rod abuts against the solid part.
[0085] Optionally, in the case where the push rod is a mechanical push rod or a hydraulic push rod, after the clamp is released, the push rod is controlled to be pushed out until the shaft workpiece abuts against the solid part.
[0086] Exemplarily, when the shaft workpiece abuts against the solid part, the limit plate is moved up and down in the vertical direction, and the distance of the up and down movement is a preset value. For example, the limit plate is moved up and down in the vertical direction by 5 mm.
[0087] Step S502: monitor the pressure value on the push rod.
[0088] In some embodiments, one side of the push rod is in contact with a shaft-like workpiece, and a pressure sensor is installed on the other side to obtain a pressure value through the pressure sensor.
[0089] Step S503: When the change in the pressure value is greater than a preset change, clamp the fixture.
[0090] The preset change amount is a preset experience value, and relevant personnel can adjust it according to actual needs.
[0091] When the change in pressure value is greater than the preset change, it indicates that there is machining debris between the shaft workpiece and the limit plate. Due to the presence of machining debris, when the limit plate moves in the vertical direction, the stationary machining debris will start to roll, causing the contact surface between the shaft workpiece and the limit plate to change, which in turn causes a significant change in the pressure on the push rod.
[0092] In another aspect of this embodiment, when the change in the pressure value is less than the preset change, it means that there is no machining debris between the shaft workpiece and the limit plate, and the subsequent steps can refer to Figure 4 The illustrated embodiments will not be described in detail here.
[0093] Step S504: Move the limiting plate in a direction away from the clamp.
[0094] Optionally, the limit plate is moved in a direction away from the fixture by a preset length, for example, the limit plate is moved in a direction away from the fixture by 4 mm.
[0095] Step S505: Control the limit plate to move toward the fixture, and control the limit plate to move in the vertical direction until the limit plate abuts against the shaft workpiece.
[0096] When the limiting plate is controlled to move toward the fixture and is controlled to move in the vertical direction, the machining debris will roll due to the relative sliding between the shaft workpiece and the limiting plate, so that the machining debris leaves between the shaft workpiece and the machining debris.
[0097] By adopting the above technical solution, the debris between the shaft workpiece and the limit plate can be removed, ensuring that the length of the shaft component exposed from the fixture meets the design requirements, thereby achieving precise processing of the shaft workpiece.
[0098] In the following embodiment, another method for removing machining debris between a shaft workpiece and a limiting plate is provided. The present application embodiment discloses a second method for using a limiting plate. Figure 6 , the method comprising: Step S601: Move the limiting plate to position the recessed area to align with the fixture.
[0099] A recessed area is provided on one side of the limit plate close to the fixture, and no through hole exists in the recessed area. Optionally, a recessed area and a regular area are provided on one side of the limit plate close to the fixture, the height of the regular area is higher than the recessed area, and the top of the recessed area is the regular area. The through hole is provided in the regular area.
[0100] Exemplarily, the relative position between the recessed area and the shaft workpiece is obtained, and the relative position is used to represent the distance difference between the recessed area and the fixture on the horizontal plane and the vertical plane. The movement of the limit plate is controlled according to the relative position.
[0101] Step S602: Loosen the clamp to allow the shaft workpiece to rest against the recessed area.
[0102] If the push rod in the fixture is a spring push rod, after the fixture is released, the push rod will automatically push the shaft workpiece out so that the shaft workpiece is pressed against the recessed area.
[0103] If the push rod in the fixture is a mechanical push rod or a hydraulic push rod, after the fixture is released, it is necessary to control the push rod to push the shaft workpiece out until the shaft workpiece abuts against the recessed area and stops pushing out the shaft workpiece.
[0104] Step S603: Move the limit plate in the vertical direction to make the shaft workpiece contact with the edge of the recessed area.
[0105] Exemplarily, according to the position of the shaft workpiece in the recessed area, the direction and distance from the shaft workpiece to the nearest recessed area are determined according to the aforementioned position, and according to the aforementioned direction and distance, the limit plate is moved in the vertical reverse direction to make the shaft workpiece contact the edge of the recessed area.
[0106] Step S604: Move the limit plate in a direction away from the fixture until the top surface of the shaft workpiece is flush with the top of the recessed area.
[0107] In some embodiments, according to the depth of the recessed area, the limiting plate is moved in a direction away from the fixture until the top surface of the shaft workpiece is flush with the top of the recessed area.
[0108] Step S605: Move the limit plate in the vertical direction until the shaft workpiece abuts against other areas of the limit plate.
[0109] Other areas refer to areas outside the recessed area on the limit plate.
[0110] When the top surface of the shaft workpiece is flush with the top of the recessed area, the limit plate is moved in the vertical direction. The depth difference between the top and the recessed area can be used to remove the machining debris attached to one end of the shaft workpiece. Therefore, the limit plate is moved in the vertical direction until the shaft workpiece rests against other areas of the limit plate.
[0111] By adopting the above technical solution, the debris between the shaft workpiece and the limiter can be removed, the part of the shaft workpiece exposed from the fixture can be accurately controlled, and the processing accuracy of the shaft workpiece can be ensured. Moreover, the whole process can be completed without the intervention of relevant personnel.
[0112] In the following embodiments, when the shaft workpiece passes through the through hole, it is necessary to ensure that the through hole is aligned with the fixture to ensure that the shaft workpiece can be smoothly clamped by the fixture. Therefore, the embodiment of the present application discloses a method for moving the limit plate. Figure 7 , the method comprising: Step S701: Obtain the relative position relationship between the through hole and the fixture.
[0113] Optionally, a first coordinate of the limiting plate is obtained. According to the position of the through hole on the limiting plate, the first coordinate is converted to obtain a second coordinate of the through hole. A third coordinate of the fixture is obtained. According to the difference between the second coordinate and the third coordinate, a relative position relationship is obtained.
[0114] Optionally, a real-time image including the through hole and the fixture is captured by a camera, and a relative positional relationship between the through hole and the fixture is obtained from the real-time image.
[0115] Step S702: when the relative position relationship does not conform to the preset relative position relationship, the moving distance and moving direction of the limit plate are calculated according to the relative position relationship.
[0116] The preset relative position relationship is a preset experience value, and relevant personnel can adjust the preset relative position relationship according to actual needs.
[0117] Optionally, a deviation value between the relative position relationship and a preset relative position relationship is calculated to obtain a moving distance and a moving direction of the limiting plate.
[0118] In some other embodiments, when the relative position relationship meets the preset relative position relationship, it means that the relative position relationship between the through hole and the clamp meets the requirements, and there is no need to adjust the relative position relationship between the through hole and the clamp.
[0119] Step S703: Control the limiting plate to move according to the moving distance and moving direction.
[0120] The limit plate is controlled to move according to the moving distance and moving direction.
[0121] By adopting the above technical solution, the through hole on the limit plate can be aligned with the fixture, ensuring that the shaft workpiece can be accurately clamped by the fixture, thereby achieving accurate processing of the shaft workpiece.
[0122] In the following embodiments, when the shaft workpiece passes through the through hole, it is also necessary to control the position of the shaft workpiece in the through hole to prevent the shaft workpiece from generating severe friction with the inner wall of the through hole. Therefore, the present application embodiment discloses a second method for moving the limit plate. Figure 8 , the method comprising: Step S801: When the shaft workpiece enters the fixture through the through hole, the position deviation between the shaft workpiece and the positioning element of the fixture is obtained.
[0123] The positioning element of the fixture is the structure on the fixture used to fix shaft workpieces.
[0124] Exemplarily, when the shaft workpiece enters the fixture through the through hole, the position information of the shaft workpiece is detected. According to the position information, the relative position between the shaft workpiece and the through hole is calculated to obtain the position deviation.
[0125] Step S802: adjusting the motion trajectory of the robot according to the position deviation.
[0126] In some embodiments, the position of the robot in the vertical direction is adjusted according to the position deviation so that the shaft workpiece clamped by the robot is aligned with the through hole on the limit plate.
[0127] Step S803: When the shaft workpiece and the side wall of the through hole are in contact with each other, determine the contact position between the shaft workpiece and the side wall.
[0128] In some other embodiments, when the shaft workpiece and the side wall of the through hole are not in contact with each other, there is no need to perform subsequent steps.
