Description

Technical Field

[0001] This invention relates to the field of rotary machining table technology, specifically an adaptive intelligent rotary machining device with self-diagnosis of faults. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by energized coils (stator windings) that acts on a rotor (such as a squirrel-cage closed aluminum frame) to create magnetoelectric torque. Electric motors are classified into DC motors and AC motors based on the power source they use. Most motors in power systems are AC motors, which can be synchronous or asynchronous (where the stator magnetic field speed and rotor rotation speed are not synchronized). During manufacturing, a rotary table is required for processing, installation, and maintenance of electric motors.

[0003] A prior art application with patent number 202323240602.8 describes a motor housing machining fixture, which includes a base and a clamping assembly. The clamping assembly includes a turntable, a clamping table, a first pin, a second pin, a clamping component, and a rotating component. The turntable passes through the base and is rotatably connected to it. The clamping table is fixedly connected to the turntable and located on one side of the turntable. The first pin is fixedly connected to the clamping table and located on the side of the clamping table away from the turntable. The second pin is fixedly connected to the clamping table and located on the side of the clamping table close to the first pin. The clamping component is mounted on the clamping table, and the rotating component drives the turntable to rotate. This design solves the problem that the machining surface needs to be constantly adjusted during machining, whereas the prior art requires frequent disassembly and reassembly of the workpiece to adjust the position, which is inconvenient. However, it is not convenient to adjust the longitudinal machining angle of the machining table, and it is difficult to form two machining tables that alternate between loading and unloading stations, resulting in low efficiency in motor machining. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive intelligent rotary machining device with fault self-diagnosis, so as to solve the problems in the prior art that it is inconvenient to adjust the longitudinal machining angle of the machining table, and it is difficult to form two machining tables to alternate between loading and unloading stations, resulting in low efficiency of motor machining.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive intelligent rotary machining device with fault self-diagnosis, comprising a base, an upper support rotatably mounted on the upper side of the base via an upper bracket and a connecting shaft, a first machining table and a second machining table rotatably mounted on the upper and lower end faces of the upper support via two rotating shafts, one end of each of the two rotating shafts being driven by a first motor via a first gear set, and one end of the connecting shaft being driven by a second motor via a second gear set, a first detection plate mounted on the upper part of the base via an electric push rod and a support frame, and a second detection plate mounted on the side wall of the upper bracket via a connecting frame, with pressure sensors mounted on one side of both the first and second detection plates.

[0006] Furthermore, both the first gear set and the second gear set are reduction gears, and the driving angle between the first gear set and the second gear set is set perpendicularly.

[0007] Furthermore, the first motor is fixedly installed in the middle of the upper support, and the second motor is fixedly installed on the outer wall of the upper bracket.

[0008] Furthermore, the first detection plate is configured as a circular plate, and the upper surface of the first detection plate is parallel to the outer end face of the processing table to be detected.

[0009] Furthermore, the second detection plate is configured as an annular detection plate, and the second detection plate is sleeved on the outer wall of the connecting shaft, while the detection end face of the second detection plate is set parallel to the side wall of the upper support.

[0010] Furthermore, both sets of pressure sensors are electrically connected to the controller inside the PLC control cabinet on the outer wall of the upper bracket, and the PLC control cabinet is equipped with an alarm, a display screen and control buttons on the outside of the cabinet door.

[0011] Its usage includes the following steps:

[0012] S1. The first motor drives the rotating shaft of the processing table to rotate through the first gear set, thereby causing the first processing table or the second processing table to rotate horizontally around the rotating shaft.

[0013] S2. The second motor drives the connecting shaft to rotate through the second gear set. The upper support is fixedly connected to the connecting shaft. Therefore, the rotation of the connecting shaft will cause the upper support to rotate longitudinally around the connecting shaft. This changes the longitudinal angle of the first and second processing tables and enables the switching of the two tables to alternate workstations.

[0014] S3. The height of the first detection plate on the base is adjustable via an electric push rod. During testing, it is raised to a position where it is flush with the lower end face of the processing table to be tested. The pressure sensor on one side of the detection plate is in standby mode. If the horizontal rotating working surface of the processing table is not level due to component wear or installation deviation, the edge of the processing table will touch the pressure sensor on the first detection plate during the rotation driven by the first motor. The sensor converts the pressure signal into an electrical signal and transmits it to the controller in the PLC control cabinet. The controller triggers the alarm to issue a warning and displays the abnormality on the display screen, reminding personnel to perform maintenance and avoid deviations in processing accuracy due to the tilt of the processing table.

[0015] S4. The second detection plate on the side wall of the upper support is fixed and its detection end face is parallel to the side wall of the upper support. A pressure sensor is also provided on one side of the detection plate. If the longitudinal flipping working surface of the upper support is not perpendicular due to loose connecting shaft or wear of gear set, the side wall of the upper support will touch the pressure sensor on the second detection plate during the longitudinal flipping process driven by the second motor. The sensor transmits the signal to the controller, and the controller also triggers the alarm and display to avoid misalignment of the dual processing table station switching or deviation of processing angle due to the tilt of the upper support.

[0016] S5. Both pressure sensors are electrically connected to the controller in the PLC control cabinet. Under normal operating conditions, the controller receives the motor's running signal and can set the rotation angle and flipping speed parameters of the processing table through the control buttons. The display screen shows the current processing status in real time. Under abnormal operating conditions, after the pressure sensor triggers the signal, the controller completes the signal processing within 1-2 seconds and simultaneously executes the alarm and displays an abnormal prompt.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes an upper support rotatably mounted on a base via an upper bracket and a connecting shaft. The upper support is equipped with a first processing table and a second processing table, which are rotatably mounted on the upper and lower sides via two rotating shafts. One end of the connecting shaft is connected to a second motor via a second gear set. The second motor and the second gear set drive the connecting shaft to rotate in both directions, thereby adjusting the longitudinal processing angle of the first and second processing tables. At the same time, the two processing tables can be switched to alternately for loading and unloading, which helps to improve the efficiency of motor processing.

[0019] 2. In this invention, a first detection plate is mounted on the upper part of the base via an electric push rod and a support frame. The upper surface of the first detection plate is parallel to the outer end face of the processing table to be tested. The first detection plate is equipped with a pressure sensor. The first detection plate is placed parallel to the lower end face of the processing table to be tested. The processing table is driven to rotate horizontally by a first motor and a first gear set. When the processing table touches the pressure sensor on one side of the detection plate, it indicates that the horizontal rotating working surface of the processing table is not kept horizontal. At this time, the pressure sensor transmits a signal to the controller, which will control the alarm to sound an alarm to warn relevant personnel to carry out maintenance and avoid affecting the processing accuracy.

[0020] 3. In this invention, a second detection plate is mounted on the side wall of the upper support via a connecting frame. The detection end face of the second detection plate is parallel to the side wall of the upper support. A pressure sensor is provided on one side of the second detection plate. During detection, the upper support is driven to rotate longitudinally by the second motor and the second gear set. When the side wall of the upper support touches the pressure sensor on one side of the detection plate, it indicates that the longitudinal rotation working surface of the upper support has not maintained longitudinal alignment. At this time, the pressure sensor transmits a signal to the controller, which will control the alarm to sound an alarm to warn relevant personnel to carry out maintenance and avoid affecting the processing accuracy.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the invention, an adaptive intelligent rotary machining device with fault self-diagnosis includes a base 1 and a PLC control cabinet. An upper support 4 is rotatably mounted on the upper side of the base 1 via an upper bracket 2 and a connecting shaft 3. A first machining table 8 and a second machining table 9 are rotatably mounted on the upper and lower end faces of the upper support 4 via two rotating shafts 7. One end of each of the two rotating shafts 7 is connected to a first motor 11 via a first gear set 10. The first motor 11 and the first gear set 10 facilitate the horizontal rotation of the machining tables for machining. One end of the connecting shaft 3 is connected to a second motor via a second gear set 5. 6. Both the first gear set 10 and the second gear set 5 are reduction gears, and the driving angle between the first gear set 10 and the second gear set 5 is set vertically. The first motor 11 is fixedly installed in the middle of the upper support 4, and the second motor 6 is fixedly installed on the outer wall of the upper bracket 2. The first processing table 8 and the second processing table 9 can be adjusted by driving the connecting shaft 3 to rotate in both directions through the second motor 6 and the second gear set 5. The rotation angle can be adjusted in both directions within 180 degrees. At the same time, the two processing tables can be switched to alternate loading and unloading positions, which is beneficial to improving the efficiency of motor processing.

[0028] like Figure 2 and Figure 3As shown, in order to perform intelligent rotation detection of the worktable, a first detection plate 12 is provided on the upper part of the base 1 via an electric push rod 13 and a support frame. A second detection plate 14 is provided on the side wall of the upper support 2 via a connecting frame. Pressure sensors 15 are provided on one side of both the first detection plate 12 and the second detection plate 14. The first detection plate 12 is set as a circular plate, and its upper surface is parallel to the outer end face of the processing table to be detected. The second detection plate 14 is set as an annular detection plate, and its second detection plate 14 is sleeved on the outer wall of the connecting shaft 3. At the same time, the detection end face of the second detection plate 14 is parallel to the side wall of the upper support 4. Both sets of pressure sensors 15 are connected to the outer wall of the upper support 4. The controller inside the PLC control cabinet on the outer wall of the upper bracket 2 is electrically connected. The PLC control cabinet is equipped with an alarm, display screen and control buttons on the outside of the cabinet door. The detection plate is set up parallel to the lower end face of the processing table to be tested or the side wall of the upper support 4. The processing table is driven to rotate horizontally or the upper support 4 is driven to rotate vertically by the motor and gear set. When the processing table or the upper support 4 touches the pressure sensor 15 on one side of the detection plate, it indicates that the horizontal rotating working surface of the processing table is not kept horizontal. At this time, the pressure sensor 15 transmits the signal to the controller, and the controller will control the alarm to sound an alarm to remind relevant personnel to carry out maintenance and avoid affecting the processing accuracy.

[0029] Its usage includes the following steps:

[0030] S1. The first motor drives the rotating shaft of the processing table to rotate through the first gear set, thereby causing the first processing table or the second processing table to rotate horizontally around the rotating shaft.

[0031] S2. The second motor drives the connecting shaft to rotate through the second gear set. The upper support is fixedly connected to the connecting shaft. Therefore, the rotation of the connecting shaft will cause the upper support to rotate longitudinally around the connecting shaft. This changes the longitudinal angle of the first and second processing tables and enables the switching of the two tables to alternate workstations.

[0032] S3. The height of the first detection plate on the base is adjustable via an electric push rod. During testing, it is raised to a position where it is flush with the lower end face of the processing table to be tested. The pressure sensor on one side of the detection plate is in standby mode. If the horizontal rotating working surface of the processing table is not level due to component wear or installation deviation, the edge of the processing table will touch the pressure sensor on the first detection plate during the rotation driven by the first motor. The sensor converts the pressure signal into an electrical signal and transmits it to the controller in the PLC control cabinet. The controller triggers the alarm to issue a warning and displays the abnormality on the display screen, reminding personnel to perform maintenance and avoid deviations in processing accuracy due to the tilt of the processing table.

[0033] S4. The second detection plate on the side wall of the upper support is fixed and its detection end face is parallel to the side wall of the upper support. A pressure sensor is also provided on one side of the detection plate. If the longitudinal flipping working surface of the upper support is not perpendicular due to loose connecting shaft or wear of gear set, the side wall of the upper support will touch the pressure sensor on the second detection plate during the longitudinal flipping process driven by the second motor. The sensor transmits the signal to the controller, and the controller also triggers the alarm and display to avoid misalignment of the dual processing table station switching or deviation of processing angle due to the tilt of the upper support.

[0034] S5. Both pressure sensors are electrically connected to the controller in the PLC control cabinet. Under normal operating conditions, the controller receives the motor's running signal and can set the rotation angle and flipping speed parameters of the processing table through the control buttons. The display screen shows the current processing status in real time. Under abnormal operating conditions, after the pressure sensor triggers the signal, the controller completes the signal processing within 1-2 seconds and simultaneously executes the alarm and displays an abnormal prompt.

[0035] The working principle and usage process of this invention are as follows: When in use, connect the external power supply, fix the workpiece to be processed on one side of the processing table using a clamp, and use the upper support 4 rotatably mounted on the upper side of the base 1 via the upper bracket 2 and the connecting shaft 3. The upper and lower end faces of the upper support 4 are provided with the first processing table 8 and the second processing table 9 rotatably mounted via two rotating shafts 7. One end of the connecting shaft 3 is connected to the second motor 6 via the second gear set 5, so that the connecting shaft 3 is driven to rotate forward and backward by the second motor 6 and the second gear set 5, thereby adjusting the longitudinal processing angle of the first processing table 8 and the second processing table 9. The rotation angle can be reversed within 180 degrees, and the two processing tables can be switched to the loading and unloading positions, which is beneficial to improving the efficiency of motor processing.

[0036] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
