The clamping claw of the mechanical claw is driven by gas or electricity, is provided with an elastic buffer structure and a positioning sensor, is used for accurately grabbing and releasing the workpiece, and avoids clamping the machined surface. The turnover table is driven by hydraulic pressure or electricity, can rotate the workpiece by 180 degrees around the horizontal shaft after fixing the workpiece, and realizes the "head-over" action. The machining process is as follows: the mechanical claw takes the workpiece to be machined from the feeding station, places the workpiece in the chuck of the machine tool one, moves the workpiece to the turnover table after machining, moves a new workpiece to the chuck of the machine tool one, moves the workpiece to the chuck of the machine tool two after the turnover table is turned over, and finally sends the finished product to the discharging station to circulate.

[0004] However, the existing equipment is only provided with one set of truss and mechanical claw, the mechanical claw needs to move back and forth between the two machine tools and the turnover table to complete the whole process, which leads to a long waiting time for feeding and discharging of the two machine tools, difficult improvement of the overall machining rhythm, limited utilization rate of the double machine tools, and longer truss and slower machining rhythm.

In addition, in the utility model, the feeding table and the discharging table are respectively located outside the machine tool one and the machine tool two, and the turnover device is arranged between the two machine tools, forming a coherent automatic path of feeding, machine tool one machining, turnover, machine tool two machining and discharging, without manual carrying and turnover of the workpiece, reducing the labor cost, and avoiding the precision error and workpiece damage caused by manual operation. In addition, in the utility model, the height of the turnover table is lower than that of the machine tool one and the machine tool two, so that the spatial interference between the turnover table and the machine tool one, the machine tool two, the mechanical claw one and the mechanical claw two can be avoided.

[0010] As a preferred implementation manner of the motor rotor shaft machining equipment, the moving platform one and the moving platform two each include a track one, a rack one and a transverse moving seat, the track one and the rack one of the moving platform one are each mounted to the top of the truss one, the track one and the rack one of the moving platform two are each mounted to the top of the truss two, the extension direction of the track one and the extension direction of the rack one are each arranged along the transverse direction, the bottom of the transverse moving seat is in sliding connection with the track one, and the transverse moving seat can slide transversely on the track one; the inside of the transverse moving seat is provided with a rotary driving mechanism one, the rotary driving mechanism one includes a rotary shaft one, the axis line of the rotary shaft one is vertically arranged, the bottom end of the rotary shaft one penetrates through the transverse moving seat, and the bottom end of the rotary shaft one is fixedly connected with a gear one, the gear one is in engagement with the rack one;

[0011] The inside of the transverse moving seat is provided with a rotary driving mechanism two, the rotary driving mechanism two includes a rotary shaft two, the axis line of the rotary shaft two is longitudinally arranged, the end of the rotary shaft two close to the vertical moving seat penetrates through the transverse moving seat, and the end of the rotary shaft two close to the vertical moving seat is fixedly connected with a gear two, the gear two is in engagement with the rack two;

[0012] The bottom of the vertical moving seat of the first moving platform is connected with the first mechanical claw, the bottom of the vertical moving seat of the second moving platform is connected with the second mechanical claw, and the vertical projection of the horizontal moving path of the first mechanical claw and the horizontal moving path of the second mechanical claw is on the same straight line.

[0013] By adopting the above structure scheme, the horizontal moving seat is driven to move along the track one and the vertical moving seat is driven to move along the track two by the gear and the rack, compared with the traditional pneumatic or hydraulic drive, the positioning accuracy of the gear and the rack drive is higher and the movement is more stable, so that the position accuracy of the first mechanical claw and the second mechanical claw when moving the workpiece can be ensured, the clamping error caused by the workpiece deviation is avoided, and the machining precision of the motor rotor shaft is improved. In addition, the vertical projection of the horizontal moving path of the first mechanical claw and the horizontal moving path of the second mechanical claw is on the same straight line, so that the workpiece is always aligned along the fixed horizontal axis during the moving process from the machine tool one to the turnover table and then to the machine tool two, the time consumption of the handover is reduced, and the workpiece collision or moving failure caused by the path misalignment is avoided.

[0014] As a preferred implementation manner of the motor rotor shaft machining device, the vertical moving seat is in a long strip plate structure, the length direction of the vertical moving seat is arranged in the vertical direction, one side of the vertical moving seat is connected with a U-shaped limiting frame, the opening of the U-shaped limiting frame faces the horizontal moving seat, and the bottom of the vertical moving seat passes through the opening of the U-shaped limiting frame.

[0015] By adopting the above structure scheme, the opening of the U-shaped limiting frame faces the horizontal moving seat, and the bottom of the vertical moving seat passes through the opening. Since the bottom of the vertical moving seat is connected with the first mechanical claw or the second mechanical claw, the U-shaped limiting frame can prevent the first mechanical claw or the second mechanical claw from being pulled out of the opening of the U-shaped limiting frame upward, that is, the maximum displacement of the first mechanical claw and the second mechanical claw upward will be limited by the U-shaped limiting frame, and physical limiting is formed.

[0016] As a preferred implementation manner of the motor rotor shaft machining device, the top of the vertical moving seat is connected with a limiting plate, and the horizontal size of the limiting plate is greater than the horizontal size of the opening of the U-shaped limiting frame.

[0017] By adopting the above structure scheme, the horizontal size of the limiting plate is greater than the opening size of the U-shaped limiting frame, which can effectively prevent the vertical moving seat from sliding out of the U-shaped limiting frame when moving downward due to excessive driving or failure, protect the safety of the equipment components and the workpiece, and reduce the production loss caused by equipment failure. In addition, the physical limiting is realized by the mechanical structure, without the need for complex control programs of additional electronic limiting sensors, so that the electrical failure points are reduced, the equipment operation reliability is improved, and the equipment manufacturing cost is reduced.

[0018] As a preferred implementation mode of the motor rotor shaft machining equipment, the turnover device comprises a base, a push rod and a sliding rail are arranged on the top of the base, the axial line of the push rod and the extension direction of the sliding rail are both arranged in the transverse direction, a sliding plate is slidably arranged on the sliding rail, one end of the push rod is connected with one side of the sliding plate in the transverse direction through a connecting plate, a rotary motor is fixedly installed on the top of the sliding plate, the output shaft of the rotary motor is vertically arranged, and the output shaft of the rotary motor is fixedly connected with the bottom of the turnover table.

[0019] With the above structure, the push rod can drive the sliding plate to move transversely along the sliding rail, the transverse position of the turnover table is fine-adjusted, the distance between the turnover table and the two machine tools can be adjusted according to the length of the motor rotor shaft, the clamping positions of the machine tool one and the machine tool two and other parameters, the machining requirements of different specifications of rotor shafts are adapted, and the versatility of the equipment is enhanced. In addition, the sliding rail provides accurate guidance for the transverse movement of the sliding plate, avoiding movement jamming; the rotary motor directly drives the turnover table to rotate horizontally by 180°, compared with hydraulic driving, the response speed is faster and the rotation angle control is more accurate, ensuring that the two ends of the workpiece are accurately oriented after being turned over, meeting the machining requirements of the machine tool two on the other end of the workpiece.

[0020] As a preferred implementation mode of the motor rotor shaft machining equipment, the top of the turnover table is provided with a clamping seat, and the clamping seat is provided with a clamping groove transversely penetrating the clamping seat.

[0021] With the above structure, the clamping groove transversely penetrates the clamping seat, and the workpiece can be embedded and positioned, preventing the workpiece from sliding, deviating or even falling during the 180° rotation of the turnover table due to centrifugal force or vibration, ensuring that the workpiece axis is aligned with the clamping axis of the machine tool two after being turned over, and avoiding subsequent clamping errors. In addition, the clamping groove transversely penetrates the clamping seat, which facilitates the mechanical claw one to move the workpiece from the machine tool one to the clamping groove, and also facilitates the mechanical claw two to grab the workpiece from the clamping groove, without the need for additional clamping and fixing actions, thereby improving the transfer efficiency of the workpiece at the turnover table.

[0022] As a preferred implementation mode of the motor rotor shaft machining equipment, the clamping seat is provided with two clamping seats, and the two clamping seats are arranged in parallel along the transverse direction.

[0023] With the above structure, the motor rotor shaft is a multi-step slender shaft, and a single clamping seat is prone to cause the middle part of the workpiece to sag and deform, and the two parallel clamping seats can support the workpiece from two transverse positions, reduce the bending deformation of the workpiece during the turnover process, and ensure the straightness and machining precision of the workpiece. When the mechanical claw one places the workpiece and the mechanical claw two takes away the workpiece, they can both be placed and taken from the middle position of the two clamping seats, so that the forces on the two ends of the workpiece are relatively balanced. In addition, the two clamping seats jointly bear the weight of the workpiece, preventing the workpiece from being pressed or structurally damaged due to excessive local stress, especially protecting the precision of the machined surface and improving the quality of the workpiece.

[0024] As a preferred implementation of the motor rotor shaft machining equipment, the two inner walls opposite in the longitudinal direction of the clamping groove are provided with elastic pads.

[0025] With the above structure, the elastic pads can avoid direct rigid contact between the inner wall of the clamping groove and the surface of the workpiece, preventing scratching and bruising of the machined surface, especially for high-precision surfaces of motor rotor shafts, effectively protecting the appearance and dimensional accuracy of the workpiece. In addition, the elastic pads have a certain elastic deformation capacity, which can closely fit the surface of workpieces of different diameters, increase the friction between the workpiece and the clamping groove, further prevent the workpiece from slipping during the turning process, and adapt to rotor shafts with small range of diameter difference, enhancing the versatility of the equipment.

In addition, the feeding plate can carry multiple workpieces to be machined, and by continuously driving the feeding plate to move, batch workpieces can be sequentially fed, which meets the batch production demand and improves the continuous operation capacity of the production line.

[0028] As a preferred implementation of the motor rotor shaft machining equipment, the top of the feeding table is provided with a conveying mechanism, and the conveying mechanism includes a conveyor belt, and the conveying direction of the conveyor belt is arranged along the longitudinal direction.

[0029] With the above structure, after the machined workpiece is moved to the conveyor belt by the mechanical claw two, the conveyor belt can automatically convey the finished product to the subsequent work station along the longitudinal direction, without manual unloading, avoiding the accumulation of unloading caused by manual waiting, and improving the unloading efficiency.

[0062] The working principle of the embodiment is as follows:

[0063] The motor rotor shafts to be processed are placed in batches on the feeding plate 35 of the feeding table 3. After starting the equipment, the rotating drive mechanism three in the feeding table 3 works: the rotating shaft three 32 drives the gear three 33 to rotate, the gear three 33 is engaged with the rack three 34 for transmission, and then the feeding plate 35 fixed with the bottom rack three 34 is driven to move longitudinally along the track three 31 at the top of the feeding table 3, so as to accurately deliver the workpiece to be processed to the grabbing range of the mechanical claw one 10, and complete the feeding preparation.

[0064] The mobile platform one 8 on the truss one 6 starts to work: the rotating drive mechanism one in the horizontal moving seat 83 works, the rotating shaft one 84 drives the gear one 85 to rotate, the gear one 85 is engaged with the rack one 82 at the top of the truss one 6, so that the horizontal moving seat 83 moves horizontally along the track one 81, and the mechanical claw one 10 is sent to the position directly above the workpiece to be processed; then, the rotating drive mechanism two on the longitudinal side of the horizontal moving seat 83 works, the rotating shaft two 89 drives the gear two 810 to rotate, the gear two 810 is engaged with the rack two 88 on one side of the vertical moving seat 87, so as to drive the vertical moving seat 87 to move vertically downward along the track two 86, and the mechanical claw one 10 clamps the workpiece.

[0065] After the mechanical claw one 10 clamps the workpiece, the workpiece is moved to the chuck of the machine tool one 1 through horizontal movement and vertical movement, the chuck clamps the workpiece, and then the machine tool one 1 starts to work to process one end of the workpiece.

[0066] After the machine tool one 1 completes the processing of one end of the workpiece, the chuck is loosened, the mechanical claw one 10 clamps the processed workpiece from the chuck of the machine tool one 1, and moves the workpiece to the turnover device 5 between the two machine tools. At this time, the push rod 53 of the turnover device 5 drives the sliding plate 55 to move horizontally along the slide rail 54, adjusts the turnover table 51 to the position corresponding to the mechanical claw one 10, loosens the mechanical claw one 10, and the workpiece falls into the clamping groove 59 of the clamping seat 58 on the top of the turnover table 51.

[0067] After the workpiece is fixed in the clamping groove 59, the rotating motor 57 of the turnover device 5 starts to work, the output shaft of the rotating motor 57 drives the turnover table 51 to rotate horizontally by 180°, so that the unprocessed end of the workpiece faces the machine tool two 2. After the rotation is completed, the push rod 53 drives the sliding plate 55 to fine-tune again along the slide rail 54, adjusts the turnover table 51 to the position corresponding to the mechanical claw two 011, and waits for the workpiece to be transferred.

[0068] The moving platform two 9 on the truss two 7 starts, and its action principle is consistent with the moving platform one 8. The moving platform two 9 makes the mechanical claw two 011 grab the overturned workpiece, and moves the workpiece to the chuck of the machine tool two 2. After the chuck clamps the workpiece, the machine tool two 2 starts to process the other end of the workpiece.

[0069] After the machine tool two 2 completes the processing of the other end of the workpiece, the chuck is loosened, the mechanical claw two 011 grabs the processed workpiece from the chuck of the machine tool two 2, and moves the workpiece to above the discharging table 4 outside the machine tool two 2. The mechanical claw two 011 is loosened, and the finished product is placed on the conveying belt 42 of the discharging table 4. The conveying belt 42 starts along the longitudinal direction, and automatically transports the finished product to the subsequent work station, completing the entire processing flow.

[0070] In the above single workpiece processing flow, the moving platform one 8 and the moving platform two 9 can work simultaneously, improving the production rhythm and improving the utilization rate of the double machine tools.

[0071] In order to realize automatic processing, in the embodiment, the existing technology can be used, such as limit switch, sensor (such as photoelectric sensor, proximity sensor, pressure sensor, etc.), to realize the accurate connection of each step through signal linkage. The specific application scenarios are as follows:

[0072] A photoelectric sensor is arranged at the end of the track three 31 of the feeding table 3 (the mechanical claw one 10 grabbing position). When the rotating driving mechanism three drives the feeding plate 35 to move along the track three 31 in the longitudinal direction, the photoelectric sensor detects the workpiece when the workpiece to be processed reaches the grabbing position with the feeding plate 35, and sends a “workpiece in position” signal to the control system. The control system triggers the moving platform one 8 to move, and drives the mechanical claw one 10 to move to the grabbing position to prepare to clamp the workpiece.

[0073] A limit switch is arranged at the initial position of the track three 31 of the feeding table 3. When the mechanical claw one 10 clamps the workpiece, the feeding plate 35 needs to return to the initial position to supplement new workpieces. When the feeding plate 35 moves to the initial position and touches the limit switch, the limit switch sends a “feeding plate 35 reset” signal to the control system, prompting that new workpieces can be supplemented, so as to avoid the misplacement of workpieces caused by the non-reset of the feeding plate 35.

[0074] A pressure sensor is arranged inside the clamping jaw of the mechanical claw one 10. When the mechanical claw one 10 is closed to clamp the workpiece, the pressure sensor detects a preset pressure value (confirming that the workpiece is clamped), and sends a “clamping success” signal to the control system. Only when the control system receives the signal, the moving platform one 8 is allowed to move the mechanical claw one 10 to move the workpiece, so as to prevent the workpiece from falling due to loose clamping.

[0075] A proximity sensor is arranged beside the chuck of the machine tool 1. When the machine tool 1 is ready to receive the workpiece, the chuck is in an open state and is zeroed, the proximity sensor detects that the chuck is ready and sends a “chuck ready for clamping” signal to the control system, the control system drives the mechanical gripper 10 to deliver the workpiece to the chuck and release it, avoiding the premature release of the mechanical gripper 10 causing the workpiece to fall inaccurately into the chuck.

[0076] A position sensor is arranged beside the spindle or machining station of the machine tool 1. When the machine tool 1 finishes machining one end of the workpiece, the spindle is reset to the initial position, the position sensor sends a “machining complete” signal to the control system, and the control system triggers the mechanical gripper 10 to move to the machine tool 1, ready to grasp the machined workpiece and move it to the turnover device 5.

[0077] A photoelectric sensor is arranged beside the clamping seat 58 of the turnover device 5. When the push rod 53 drives the sliding plate 55 along the sliding rail 54 to adjust the turnover platform 51 to the position for receiving the workpiece, the photoelectric sensor detects that the turnover platform 51 is in place and sends a “turnover platform 51 ready” signal to the control system, allowing the mechanical gripper 10 to release the workpiece and allowing the workpiece to fall into the clamping groove 59.

[0078] An angle sensor is arranged beside the rotary motor 57 of the turnover platform 51. When the rotary motor 57 drives the turnover platform 51 to rotate horizontally by 180°, the angle sensor detects the preset angle (180°) and sends a “turnover complete” signal to the control system, which drives the push rod 53 to fine-tune the position of the turnover platform 51 and triggers the mechanical gripper 10 to move to the turnover platform 51, ready to grasp the turned workpiece.

[0079] A pressure sensor is arranged in the clamping groove 59. When the mechanical gripper 10 clamps the workpiece and moves upward to disengage from the clamping groove 59, the pressure sensor detects that the pressure is gone and sends a “workpiece has been removed” signal to the control system, which drives the turnover platform 51 to reset to the initial position and wait to receive the next workpiece moved from the machine tool 1.

[0080] A pressure sensor is arranged inside the chuck of the machine tool 2. When the mechanical gripper 10 places the turned workpiece into the chuck of the machine tool 2 and the chuck clamps the workpiece, the pressure sensor detects the preset clamping force and sends a “clamping success” signal to the control system, which triggers the machine tool 2 to start machining the other end of the workpiece, avoiding displacement of the workpiece during machining due to the chuck not being clamped.

[0081] Consistent with the principle of the machine tool 1, a position sensor is arranged beside the spindle or machining station of the machine tool 2. When machining of the other end of the workpiece is complete and the spindle is reset, the position sensor sends a “machining complete” signal to the control system, which drives the mechanical gripper 10 to move to the machine tool 2, ready to grasp the finished workpiece and move it to the discharge table 4.

[0082] A photoelectric sensor is arranged at the entrance of the conveying belt 42 of the unloading station 4, which sends a "conveying belt 42 ready" signal to the control system when the conveying belt 42 is in standby state and no finished product is accumulated, so that the control system allows the mechanical gripper 2011 to place the finished workpiece on the conveying belt 42, avoiding workpiece collision caused by finished product accumulation.

[0083] A photoelectric sensor is arranged at the middle of the conveying belt 42, which sends a "finished product has been conveyed" signal to the control system when the finished workpiece moves along with the conveying belt 42 and passes through the sensor, so that the control system records the number of finished products.
