Description

Technical Field

[0001] This invention relates to the field of motor component processing technology, and in particular to a servo motor stator core stacking equipment. Background Technology

[0002] The stator core of a servo motor is a core component of the motor's magnetic circuit. Its assembly precision and operational safety directly determine the electromagnetic performance, operational stability, and service life of the servo motor. The stator core is formed by stacking and pressing multiple sets of silicon steel laminations. The stacking and pressing process is the core process in core manufacturing. The alignment, flatness, and standardized operation of the laminations during the stacking process are crucial to ensuring the quality of the finished core and preventing production safety accidents.

[0003] Currently, there are general operating procedures for the stacking and pressurizing of servo motor stator cores in the industry. The core control requirements include two main dimensions: First, during the core pressurization process, operators must monitor the core condition throughout the process and promptly check for quality abnormalities such as unilateral arching, tooth twisting, and lamination misalignment to avoid quality problems such as uneven magnetic circuits, abnormal motor noise, and reduced efficiency caused by stacking deformation and misalignment. Second, clearly define the dangerous operating areas of the pressurizing equipment and strictly prohibit operators from putting their hands into the pressurization danger zone to avoid safety accidents caused by mechanical crushing.

[0004] However, the existing observation methods rely solely on fixed-point visual observation by operators, which has a very limited scope. It can only cover a local visible area of ​​the iron core and cannot achieve real-time dynamic monitoring of the entire iron core and the entire pressurization process. It is very easy to miss minor anomalies such as local lamination misalignment, slight tooth distortion, and edge arching, resulting in defective products being released. At the same time, there is no mandatory constraint mechanism for manual observation, which depends entirely on the subjective operation awareness of the operators. There is a risk of non-standard operation such as observation gaps, omissions, and perfunctory observation, resulting in poor quality control stability and difficulty in ensuring product consistency.

[0005] At the safety management level, existing safety protection measures rely solely on soft management methods such as regulations and verbal warnings, only constraining the behavior of workers without setting up mandatory control mechanisms such as physical barriers and intelligent protection. During pressurization operations, if sudden abnormalities such as misalignment of punches or local bulges occur, workers are prone to instinctively reaching out to adjust them, which is a violation of regulations. There are no mandatory protective measures to prevent dangerous behavior, greatly increasing the probability of safety accidents such as hand crushing and mechanical injuries, resulting in prominent operational safety hazards. Summary of the Invention

[0006] This invention relates to a servo motor stator core stacking equipment, which solves the problems of limited observation range of the stator core during the pressurization process of servo motor stator core stacking, lack of mandatory constraints that easily lead to missed detection of minor defects, difficulty in ensuring product consistency, and reliance on system warnings without mandatory intelligent protection devices, which cannot prevent personnel from reaching out to adjust the core in violation of regulations, resulting in prominent quality control problems and mechanical injury safety hazards.

[0007] This invention provides a servo motor stator core stacking device, specifically including: a C-type hydraulic press machine, wherein an internal expansion elastic sleeve is fixedly installed on the worktable below the throat of the C-type hydraulic press machine, a hydraulic cylinder connected to the conical core inside the internal expansion elastic sleeve is installed inside the worktable, the hydraulic cylinder is connected to the hydraulic control circuit of the C-type hydraulic press machine, the hydraulic cylinder is controlled by the matching control components of the C-type hydraulic press machine, and an annular pressure plate is fixedly installed at the bottom of the press head of the C-type hydraulic press machine;

[0008] The C-type hydraulic press machine has an annular groove coaxially arranged on the pressing table, which is mounted in the same direction as the internal expansion elastic sleeve. An annular block is rotatably mounted in the annular groove through a bearing, and gear teeth are evenly installed on the outer circumferential surface of the annular block. A drive groove communicating with the annular groove is also provided on the rear side of the worktable. A drive gear is provided in the drive groove, and the drive gear meshes with the gear teeth. An installation groove a is provided on the rear end face of the throat of the C-type hydraulic press machine. A motor is installed in the installation groove a, and the end of the motor shaft extends into the drive groove and is keyed to the drive gear.

[0009] A WIFI wireless camera is fixedly attached to the top of the annular block by a nail-free camera bracket, with the camera end of the WIFI wireless camera facing the inward-expanding elastic sleeve.

[0010] Furthermore, the rear end face of the throat of the C-type hydraulic press machine is provided with a mounting groove b. The mounting groove b is lower than the press head of the C-type hydraulic press machine. An on / off switch is fixedly installed inside the mounting groove b. The on / off switch is a tactile switch, and the button end of the on / off switch protrudes from the mounting groove b.

[0011] Furthermore, a rubber block is fixedly installed at the rear end of the press head of the C-type hydraulic press machine. The rubber block and the mounting groove b are on the same vertical line. The bottom end face of the rubber block and the bottom end face of the press head are on the same horizontal plane. The rear end face of the rubber block is in contact with the rear end face of the throat of the C-type hydraulic press machine. A pressing notch is opened between the bottom end face and the rear end face of the rubber block.

[0012] When the rubber block corresponds to the position of the mounting groove b, the rear end face of the rubber block presses against the button end of the on / off switch, and the on / off switch is in the pressed start state.

[0013] Furthermore, the C-type hydraulic press machine is provided with an observation platform on the front side, and a moving wheel is installed on the bottom end face of the observation platform; a rearwardly extending guide plate is fixedly installed on the bottom end face of the observation platform; a guide groove adapted to the guide plate is opened on the bottom end face of the C-type hydraulic press machine body, and the guide groove and the guide plate are slidably inserted into each other; a pull rod is fixedly installed on the front end face of the observation platform.

[0014] Furthermore, a transparent observation protective plate extending upward is fixedly installed on the rear end face of the observation platform; a cutting surface is opened between the top face and the front face of the observation platform, and a touch screen with built-in multimedia decoding is fixedly installed on the inclined surface of the cutting surface; when the rear end face of the transparent observation protective plate comes into contact with the C-type hydraulic press machine, the transparent observation protective plate completely blocks the front opening end of the throat of the C-type hydraulic press machine.

[0015] Furthermore, a sliding cavity is provided inside the upper part of the observation platform, and a slot communicating with the sliding cavity is provided on both the left and right ends of the observation platform; a plug is slidably inserted into each of the two slots, and a sliding baffle is fixedly installed at the opposite ends of the two plugs, with the sliding baffle slidably inserted into the sliding cavity; a pressure plate is fixedly installed at the other end of each of the two plugs, and the pressure plate is located outside the slot.

[0016] Furthermore, the two sliding baffles are fixedly connected by a spring connector; in its natural state, the pressure plate does not contact the observation platform.

[0017] Furthermore, proximity switches and sensing blocks that can sense and cooperate with them are respectively fixedly installed on the opposite surfaces of the two sliding baffles; in the natural state of the spring connector, the sensing blocks are not within the sensing range of the proximity switches; when both pressure plates are in contact with the observation platform, the spring connector is in a compressed state, while the sensing blocks are within the sensing range of the proximity switches.

[0018] Furthermore, a buzzer is installed on the front face of the observation platform, and a WIFI module is installed inside the observation platform. The WIFI wireless camera and the touch screen establish a wireless communication connection through the WIFI module.

[0019] The observation platform is also equipped with a microcontroller that is electrically connected to the motor, on / off switch, buzzer, touch screen and proximity switch. The microcontroller is connected to the control power circuit of the C-type hydraulic press machine through a cable and obtains working power.

[0020] When the proximity switch is in the pressed start state, the proximity switch feeds a feedback signal to the microcontroller, which controls the motor shaft to rotate at a constant speed. During operation, if the proximity switch does not sense the sensing block, it continues to feed a feedback signal to the microcontroller, which then controls the buzzer to start an alarm. If the proximity switch senses the sensing block, the buzzer remains off.

[0021] This invention provides a servo motor stator core stacking device, which has the following beneficial effects:

[0022] This invention relies on a coaxial rotary transmission mechanism composed of a motor in the mounting slot a behind the throat of a C-type hydraulic press, a drive gear inside the drive slot, outer circumferential teeth of the annular block, bearings, and annular groove. When the press head presses down, the rubber block presses against the switch inside the mounting slot b. After receiving the signal, the microcontroller drives the motor to run at a constant speed. The drive gear meshes with the teeth of the annular block, causing the annular block, supported by the bearings, to rotate coaxially and at a constant speed around the inner expansion elastic sleeve in the annular groove. A WIFI wireless camera, fixed to the top of the annular block by a nail-free camera bracket, moves synchronously around the annular block. The camera end is aimed at the stator core outside the inner expansion elastic sleeve throughout the entire process, which can completely capture the entire outer circumference of the core. This completely solves the control shortcomings of traditional equipment, where fixed-point cameras can only observe locally, and defects such as unilateral arching, tooth distortion, and lamination misalignment are easily missed.

[0023] After the press-fitting full-area monitoring process of this invention is started, if the operator does not press the pressure plates on both sides of the observation platform with both hands simultaneously, the proximity switch will continuously transmit signals to the microcontroller. The microcontroller will continuously drive the buzzer at the front of the observation platform to sound and light alarm. When the operator presses the two pressure plates inward with both hands, the insert block drives the sliding baffles on both sides to move in opposite directions to compress the spring connector. After the sensing block enters the sensing range of the proximity switch, the buzzer will stop alarming. This structure forms a rigid constraint, requiring the operator to continuously press the pressure plates on both sides throughout the entire pressing process. The operator's hands are restricted to the outside of the observation platform and cannot be extended into the dangerous area of ​​the C-type hydraulic press-fitting machine throat. This makes up for the safety loophole of relying solely on regulations to prohibit hand insertion without physical enforcement. At the same time, it also forcibly limits the operator's position. When the operator is in front of the touch screen, the operator is forced to observe the real-time full-area image of the iron core transmitted by the WIFI wireless camera throughout the process, and promptly identify defects such as unilateral arching, tooth twisting, and lamination misalignment during the iron core pressing process, preventing the operator from omitting the observation steps.

[0043] Example: Please refer to Figures 1 to 13 :

[0044] This invention proposes a servo motor stator core stacking device, comprising: a C-type hydraulic press machine 1, an internal expansion elastic sleeve 101 fixedly installed on the worktable below the throat of the C-type hydraulic press machine 1, a hydraulic cylinder connected to the conical core inside the internal expansion elastic sleeve 101 installed inside the worktable, the hydraulic cylinder being connected to the hydraulic control circuit of the C-type hydraulic press machine 1, the hydraulic cylinder being controlled by the matching control components of the C-type hydraulic press machine 1, and an annular pressure plate 104 fixedly installed at the bottom of the press head of the C-type hydraulic press machine 1;

[0045] The C-type hydraulic press machine 1 has an annular groove 1011 coaxially arranged with the internal expansion elastic sleeve 101 on the pressing table. An annular block 102 is rotatably installed in the annular groove 1011 through a bearing 1010. Gear teeth 109 are evenly installed on the outer circumferential surface of the annular block 102. A drive groove 1012 connected to the annular groove 1011 is also provided on the rear side of the worktable. A drive gear 1013 is provided in the drive groove 1012 and meshes with the gear teeth 109. An installation groove a107 is provided on the rear end face of the throat of the C-type hydraulic press machine 1. A motor 106 is installed in the installation groove a107. The shaft end of the motor 106 extends into the drive groove 1012 and is keyed to the drive gear 1013.

[0046] A WIFI wireless camera 105 is fixedly attached to the top of the annular block 102 by a nail-free camera bracket 108. The camera end of the WIFI wireless camera 105 faces the inward elastic expansion sleeve 101. Therefore, the real-time image of the iron core captured by the WIFI wireless camera 105 can be wirelessly transmitted to the touch screen 205, so that the operator can view the forming status of the iron core surface in real time.

[0047] The C-type hydraulic press machine 1 has a mounting groove b1014 on the rear end face of the throat. The mounting groove b1014 is lower than the press head of the C-type hydraulic press machine 1. An on / off switch 1015 is fixedly installed inside the mounting groove b1014. The on / off switch 1015 is a tactile switch, and the button end of the on / off switch 1015 protrudes from the mounting groove b1014. A rubber pressing block 1016 is fixedly installed at the rear end of the press head of the C-type hydraulic press machine 1. The rubber pressing block 1016 is in the same position as the mounting groove b1014. A vertical line is drawn, with the bottom end face of the rubber block 1016 and the bottom end face of the pressure head on the same horizontal plane. The rear end face of the rubber block 1016 is in contact with the rear end face of the throat of the C-type hydraulic press machine 1. A pressing notch 1017 is opened between the bottom end face and the rear end face of the rubber block 1016. When the rubber block 1016 corresponds to the position of the mounting groove b1014, the rear end face of the rubber block 1016 presses against the button end of the on / off switch 1015, and the on / off switch 1015 is in the pressed start state.

[0048] The C-type hydraulic press machine 1 has an observation platform 2 on its front side, with casters 208 mounted on the bottom surface of the observation platform 2. A rearward-extending guide plate 201 is fixedly mounted on the bottom surface of the observation platform 2. A guide groove 103 adapted to the guide plate 201 is opened on the bottom surface of the main body of the C-type hydraulic press machine 1, and the guide groove 103 and the guide plate 201 are slidably inserted into each other. A pull rod 202 is fixedly mounted on the front surface of the observation platform 2. An upward-extending transparent observation and protection plate 207 is fixedly mounted on the rear surface of the observation platform 2. A cutting surface 204 is opened between the top surface and the front surface of the observation platform 2, and a touch screen 205 with built-in multimedia decoding is fixedly mounted on the inclined surface of the cutting surface 204. When the rear surface of the transparent observation and protection plate 207 contacts the C-type hydraulic press machine 1, the transparent observation and protection plate 207 completely blocks the front opening end of the throat of the C-type hydraulic press machine 1. The transparent observation and protection plate 207 forms a basic physical shield for the dangerous area of ​​press-fitting while ensuring visual observation.

[0049] The observation platform 2 has a sliding cavity 2015 located at its upper interior. Each of the left and right end faces of the observation platform 2 has a slot 209 communicating with the sliding cavity 2015. A plug 2010 is slidably inserted into each slot 209. A sliding baffle 2011 is fixedly installed at the opposite end of each plug 2010, and the sliding baffle 2011 is slidably inserted into the sliding cavity 2015. A pressure plate 206 is fixedly installed at the other end of each plug 2010, located outside the slot 209. A spring connector 20 connects the two sliding baffles 2011. 12 are fixedly connected; in the natural state of the spring connector 2012, the pressure plate 206 is not in contact with the observation platform 2; the opposite surfaces of the two sliding baffles 2011 are respectively fixedly installed with a proximity switch 2013 and a sensing engagement block 2014 that can sense and cooperate with it; in the natural state of the spring connector 2012, the sensing engagement block 2014 is not within the sensing range of the proximity switch 2013; when both pressure plates 206 are in contact with the observation platform 2, the spring connector 2012 is in a compressed state, while the sensing engagement block 2014 is within the sensing range of the proximity switch 2013.

[0050] The observation platform 2 is equipped with a buzzer 203 on its front end and a WIFI module 2016 inside. The WIFI wireless camera 105 and the touch screen 205 establish a wireless communication connection via the WIFI module 2016. The observation platform 2 also contains a microcontroller 2017 that is electrically connected to the motor 106, the on / off switch 1015, the buzzer 203, the touch screen 205, and the proximity switch 2013. The microcontroller 2017 is connected to the control power circuit of the C-type hydraulic press machine 1 via a cable and obtains operating power. Yes; when the proximity switch 2013 is in the pressed start state, the proximity switch 2013 provides a feedback signal to the microcontroller 2017, and the microcontroller 2017 controls the shaft end of the motor 106 to rotate at a constant speed. During operation, if the proximity switch 2013 does not sense the sensing engagement block 2014, the proximity switch 2013 continues to provide a feedback signal to the microcontroller 2017, and the microcontroller 2017 controls the buzzer 203 to start the alarm. If the proximity switch 2013 senses the sensing engagement block 2014, the buzzer 203 remains in the off state.

[0051] The working principle of this embodiment:

[0052] Before the stacking operation, the operator holds the lever 202 and pulls the observation platform 2 forward. The observation platform 2 is displaced by the bottom moving wheels 208. The guide plate 201 extending backward from the bottom of the observation platform 2 slides forward and is pulled out along the guide groove 103 on the bottom end face of the C-type hydraulic press machine 1. The transparent observation protective plate 207 is simultaneously detached from the C-type hydraulic press machine 1, and the front opening of the throat of the C-type hydraulic press machine 1 is fully exposed. The operator stacks multiple servo motor stator iron core laminations to be stacked in sequence and fits them together on the outside of the inner expansion elastic sleeve 101 placed in the center of the workbench. Then, the hydraulic control circuit is started through the control components of the C-type hydraulic press machine 1 to drive the hydraulic cylinder inside the workbench to move. The hydraulic cylinder drives the inner cone core of the inner expansion elastic sleeve 101 to generate axial displacement. Using the conical surface extrusion action, the inner expansion elastic sleeve 101 is uniformly radially expanded, and the outer wall is tightly attached to the inner hole of the iron core lamination. The radial tension force holds the iron core lamination tightly.

[0053] After the iron core lamination is fixed, the operator holds the pull rod 202 and pushes the observation platform 2 backward until the transparent observation protective plate 207 on the rear end of the observation platform 2 is close to the outer wall of the C-type hydraulic press machine 1. The transparent observation protective plate 207 completely blocks the opening end on the front side of the throat of the C-type hydraulic press machine 1, forming a basic physical shield for the press-pressing danger area.

[0054] Because the WIFI wireless camera 105 and the touch screen 205 establish a wireless communication connection through the WIFI module 2016, the operator can start the WIFI wireless camera 105 by operating the touch screen 205. The real-time image of the iron core captured by the WIFI wireless camera 105 is wirelessly transmitted to the touch screen 205, and the operator can view the forming status of the iron core surface in real time.

[0055] The operator controls the downward feed of the press head through the control components of the C-type hydraulic press machine 1. The annular pressure plate 104 at the bottom of the press head presses down synchronously, applying axial pressure to the iron core sleeved on the outside of the inner expansion elastic sleeve 101, thus completing the pressing and forming of the iron core laminations.

[0056] During the pressing process, the rubber block 1016 fixed at the rear end of the press head moves downward synchronously. The inclined surface of the pressure notch 1017 opened between the bottom end face and the rear end face of the rubber block 1016 first contacts the button end of the on / off switch 1015 inside the mounting groove b1014. The on / off switch 1015 is triggered and turned on by the pressure notch 1017, transmitting the whole machine linkage start signal to the microcontroller 2017.

[0057] After receiving the trigger signal from the on / off switch 1015, the microcontroller 2017 drives the motor 106 in the mounting slot a107 to rotate at a constant speed. The shaft of the motor 106 is keyed to the drive gear 1013 in the drive slot 1012. The drive gear 1013 meshes with the gear teeth 109 evenly arranged on the outer circumference of the annular block 102, thereby driving the annular block 102, which is supported by the bearing 1010 in the annular slot 101, to rotate at a constant speed around the inner expansion elastic sleeve 101.

[0058] The ring block 102 synchronously drives the WIFI wireless camera 105 above to move around the outer circumference of the iron core. The WIFI wireless camera 105's shooting range completely covers the entire outer circumference of the iron core, solving the shortcomings of traditional fixed-point observation which has limited field of view, cannot monitor the entire area in real time, and is prone to overlooking defects such as single-sided arching of the iron core, tooth twisting, and lamination offset.

[0059] After the motor 106 starts full-area rotation monitoring, if the proximity switch 2013 does not capture the sensing signal of the sensing engagement block 2014, the microcontroller 2017 will continuously drive the buzzer 203 on the front face of the observation platform 2 to continuously sound and light alarm, forcibly reminding the operator to perform the hand restraint operation.

[0060] At this time, the operator needs to press the pressure plates 206 on the left and right sides of the observation platform 2 inward with his left and right hands respectively. The two pressure plates 206 will drive the corresponding plugs 2010 to slide along the slots 209 into the sliding cavity 2015. The sliding baffles 2011 connected to the inner side of the two plugs 2010 will move towards each other in sync, and the spring connector 2012 connected between the two sliding baffles 2011 will be compressed.

[0061] When the two pressure plates 206 are completely in contact with the outer wall of the observation platform 2, the spring connector 2012 is in a compressed state. The sensing block 2014 on one side of the sliding baffle 2011 enters the sensing range of the proximity switch 2013 on the other side of the sliding baffle 2011. The proximity switch 2013 transmits a sensing signal to the microcontroller 2017. The microcontroller 2017 cuts off the power supply to the buzzer 203, and the alarm stops.

[0062] This structure creates a rigid constraint, requiring operators to continuously press the pressure plates 206 on both sides throughout the stacking process. Their hands are restricted to the outside of the observation platform 2, preventing them from reaching into the dangerous area of ​​the throat of the C-type hydraulic press machine 1. This compensates for the safety loophole of relying solely on regulations to prohibit hand insertion without physical enforcement. It also forcibly limits the position of the operator, who is positioned in front of the touch screen 205 and can simultaneously observe the real-time image of the entire iron core transmitted by the WIFI wireless camera 105 throughout the process, promptly identifying defects such as unilateral arching, tooth twisting, and lamination misalignment during the iron core stacking process.

[0063] After the stator core is stacked and formed, the operator releases the pressure plates 206 on both sides. The spring connector 2012 rebounds and pushes the two sliding baffles 2011 away. Then, the operator controls the C-type hydraulic press machine 1 to lift the pressure head upward through the matching control components. The rubber pressure block 1016 moves upward and disengages from the button of the on / off switch 1015. The on / off switch 1015 is turned off. After receiving the disconnection signal, the microcontroller 2017 controls the motor 106 to stop running. The whole-area core surround monitoring process is terminated simultaneously. Then, the operator pulls the observation platform 2 forward and drives the hydraulic cylinder to reset through the matching control components of the C-type hydraulic press machine 1. This causes the inner expansion elastic sleeve 101 to contract and return to its original position, releasing the radial clamping and fixing of the inner expansion elastic sleeve 101 on the stator core. The stacked stator core can then be taken out.
