Abstract

This application relates to an automated conveying device for motor shaft processing, comprising a feeding mechanism including a frame, a contact block, a lifting block, and a drive assembly. A conveyor belt drives the frame, and a stop bar is provided on the frame. One end of the stop bar abuts against the end of the conveyor belt, and a baffle is provided on the stop bar. When the conveyor belt transports the blank to the end, the blank rolls above the stop bar and abuts against the baffle. The lifting block is slidably connected to the frame and has a limit groove. The contact block is slidably connected to the frame, and a contact plate is provided on the frame. The drive assembly drives the movement of the lifting block and the contact block.

Description

Technical Field

[0001] This utility model relates to the field of material transfer devices, and in particular to an automated material transfer device for machining motor shafts. Background Technology

[0002] During the machining process of the motor shaft, both ends of the bar stock blank need to be turned separately. In existing technology, two lathes are often used to turn both ends of the blank separately. However, as the core component of the motor transmission system, the machining process of the motor shaft requires high precision. The traditional manual feeding method has problems such as low efficiency, high labor intensity, and easy damage to the workpiece due to human operation error or machining accuracy deviation due to clamping error, which is difficult to meet production needs. Utility Model Content

[0003] To facilitate the feeding of workpieces during the machining of motor shafts, this application provides an automated transfer and feeding device for motor shaft machining.

[0004] The automated transfer and material conveying device for motor shaft machining provided in this application adopts the following technical solution: An automated conveying device for machining motor shafts includes a feeding mechanism for sequentially feeding blanks. The feeding mechanism includes a frame, abutment blocks, several lifting blocks, and a drive assembly. A conveyor belt is drivenly connected to the frame, and several stop rods are provided on the frame. One end of each of the stop rods abuts against the end of the conveyor belt, and each of the stop rods is provided with a baffle. When the conveyor belt transports the blank to the end, the blank rolls above the stop rod and abuts against the baffle. The lifting blocks are synchronously slidably connected to the frame, and each of the lifting blocks has a limit groove. The abutment block is slidably connected to the frame along a sliding direction perpendicular to the lifting block, and the frame is provided with an abutment plate opposite to the abutment block. The drive assembly synchronously drives the movement of the lifting blocks and the abutment blocks. When the blank moves to abut against the baffle, the drive assembly drives the lifting blocks to rise so that the blank enters the limit groove, and synchronously drives the abutment blocks to move so that both ends of the blank in the axial direction abut against the abutment block and the abutment plate, respectively.

[0005] By adopting the above technical solution, the conveyor belt can continuously transport the blanks in sequence without manual loading one by one; the stop rod and the baffle work together to ensure that the blanks stop precisely at the end of the conveying process, avoiding the chaotic arrangement caused by the blanks rolling randomly, laying the foundation for subsequent positioning, realizing the dual key functions of automatic conveying and precise positioning of motor shaft blanks, and facilitating the feeding operation of workpieces during the motor shaft processing.

[0006] Preferably, the drive assembly includes a hinge rod, a sliding seat, an adjusting block, and a limiting member. The sliding seat is slidably connected to the frame along the sliding direction of the abutment block. The abutment block is fixedly connected to the sliding seat. The adjusting block is installed on the sliding seat and has a through hole that can be adapted to the hinge rod. One end of the hinge rod is hinged to the lifting block, and the other end passes through the through hole and is slidably connected in the through hole. The limiting member is used to limit the position of the adjusting block.

[0007] By adopting the above technical solution, the two synchronous actions can be achieved with a single drive through the cooperation of the hinge rod and the adjusting block, reducing equipment cost and failure rate. The position of the adjusting block is adjustable and can be adapted to motor shaft blanks of different lengths and diameters. By rotating the adjusting block to finely adjust its position, the travel of the abutment block can be changed, improving the versatility of the device.

[0008] Preferably, the limiting member includes two adjusting bolts, one end of each adjusting bolt being threaded through a sliding seat and abutting against the outer wall of the adjusting block.

[0009] By adopting the above technical solution, after the adjusting bolt abuts against the outer wall of the adjusting block, a rigid constraint can be formed to prevent the adjusting block from shifting due to vibration or force during equipment operation, thus limiting the rotation of the adjusting block during use; when changing blanks of different lengths, the angle of the adjusting block can be adjusted by loosening the adjusting bolt.

[0010] Preferably, a sorting rod is slidably connected to the frame along the transmission direction perpendicular to the conveyor belt. A first electric cylinder is provided on the frame, and the piston rod of the first electric cylinder is fixedly connected to the sorting rod. The sorting rod reciprocates along the transmission direction perpendicular to the first electric cylinder to perform lateral alignment and sorting of the blanks on the conveyor belt.

[0011] By adopting the above technical solution, when the conveyor belt is conveying, the blank may shift laterally due to placement deviation and inertia. The sorting rod can push the shifted blank to the same side to prevent surface damage caused by the blank colliding with each other. When the sorted blank is conveyed to the end, it can abut the baffle in a uniform lateral position, reduce the alignment deviation between the lifting block limit groove and the blank, and reduce the possibility of positioning failure caused by blank shift.

[0012] Preferably, it also includes an infrared sensor and a controller. The infrared sensor is mounted on the frame and faces the sliding block. The controller is mounted on the frame and is electrically connected to the infrared sensor and each power source. When the sliding block moves the blank to the point where it covers the infrared sensor, the controller controls each power source to stop operating. When the blank is removed and the infrared sensor is exposed, the controller controls each power source to start according to a preset program.

[0013] By adopting the above technical solution, unmanned operation is achieved: after the transfer mechanism takes away the blank, the infrared sensor is no longer blocked and sends a "material taking completed" signal to the controller. The controller then starts each power source according to the preset program and automatically enters the next round of feeding-positioning process without manual start and stop, thus improving production efficiency.

[0014] Preferably, the device further includes a transfer mechanism for transferring blanks and workpieces. The transfer mechanism includes a robotic arm and two pneumatic grippers. The two pneumatic grippers are respectively fixed to the execution end of the robotic arm via connecting seats, and the gripping directions of the two pneumatic grippers are arranged perpendicularly.

[0015] By adopting the above technical solution, the two pneumatic grippers can work together in a division of labor. One grips the blank positioned on the feeding mechanism and sends it to the processing equipment; the other grips the processed workpiece and sends it to the unloading table. There is no need for manual labor to go back and forth between the feeding area and the processing area, which improves the overall production rhythm. The gripping direction of the two grippers is set vertically, which can meet the workpiece posture requirements of different workstations. There is no need to change the grippers, which improves the flexibility of transportation.

[0016] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model, by setting up a feeding mechanism, allows the conveyor belt to continuously transport blanks in sequence without the need for manual loading one by one; the stop rod and the baffle work together to ensure that the blanks stop precisely at the end of the conveying process, avoiding the chaotic arrangement caused by the random rolling of the blanks, laying the foundation for subsequent positioning, and realizing the dual key functions of automatic conveying and precise positioning of motor shaft blanks, which facilitates the feeding operation of workpieces during the motor shaft processing. 2. By setting up a drive component, the hinge rod and the adjusting block cooperate to achieve synchronous action of two parts with one drive, reducing equipment cost and failure rate. The position of the adjusting block can be adjusted to adapt to motor shaft blanks of different lengths and diameters. By rotating the adjusting block to finely adjust its position, the movement stroke of the abutment block can be changed, improving the versatility of the device. 3. By setting up a sorting rod, the blank may shift laterally due to placement deviation and inertia during conveyor belt transport. The sorting rod can push the shifted blank to the same side to prevent surface damage caused by the blank colliding with each other. When the sorted blank is conveyed to the end, it can abut against the baffle in a uniform lateral position, reducing the alignment deviation between the lifting block limit groove and the blank, and reducing the possibility of positioning failure caused by blank shift.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0026] This application discloses an automated transfer and material conveying device for motor shaft processing.

[0027] Reference Figure 1 This embodiment of an automated transfer and material conveying device for motor shaft processing includes a feeding mechanism 1 for sequential feeding of blanks and a transfer mechanism 2 for transferring blanks and workpieces.

[0028] Reference Figure 3 and Figure 5 The feeding mechanism 1 includes a frame 3, an abutment block 4, two lifting blocks 5, and a drive assembly 6. A conveyor belt 7 is driven and connected to the frame 3. A motor 8 is fixedly connected to the frame 3. The motor 8 is used to drive the conveyor belt 7 for transmission. Two stop rods 9 are detachably connected to the frame 3. One end of the length direction of the two stop rods 9 abuts against one side of the end of the transmission belt. Baffles 10 are fixedly connected to the two stop rods 9 respectively. When the conveyor belt 7 transports the blank to the end, the blank rolls above the stop rod 9 and abuts against the baffle 10.

[0029] Reference Figure 2and Figure 4 A lifting seat 11 is slidably connected to the frame 3 in the vertical direction. Two lifting blocks 5 are simultaneously fixedly connected to the lifting seat 11. A second electric cylinder 12 is fixedly connected to the frame 3. One end of the output shaft of the second electric cylinder 12 is fixedly connected to the lifting seat 11. The second electric cylinder 12 is used to drive the sliding of the lifting seat 11. Limiting grooves 13 are respectively opened at the upper ends of the two lifting blocks 5. The limiting grooves 13 are gradually widened from the end near the bottom surface of the frame 3 to the side away from the bottom surface of the frame 3. When the two lifting blocks 5 are in the initial position, the limiting grooves 13 are located below the stop rod 9. When the two lifting blocks 5 are in the termination position, the limiting groove 13 is located above the termination rod 9. The abutting block 4 slides and is connected to the frame 3 along the sliding direction perpendicular to the lifting seat 11. The frame 3 is fixedly connected with an abutting plate 14 that is opposite to the abutting block 4. The driving component 6 drives the lifting block 5 and the abutting block 4 to move synchronously. When the blank moves to abut against the baffle 10, the driving component 6 drives the lifting block 5 to rise so that the blank enters the limiting groove 13, and drives the abutting block 4 to move synchronously so that the two ends of the blank in the axial direction abut against the abutting block 4 and the abutting plate 14 respectively.

[0030] Reference Figure 2 and Figure 4 The conveyor belt 7 can continuously transport the blanks in sequence without manual loading. The stop rod 9 and the baffle 10 work together to ensure that the blanks stop precisely at the end of the conveying process, avoiding the chaotic arrangement caused by the blanks rolling randomly. This lays the foundation for subsequent positioning and realizes the dual key functions of automatic conveying and precise positioning of blanks on the 8-axis motor, which facilitates the feeding of workpieces during the 8-axis motor machining process.

[0031] Reference Figure 2 and Figure 6 The drive assembly 6 includes a hinge rod 15, a sliding seat 16, an adjusting block 17, and a limiting member 18. The sliding seat 16 is slidably connected to the frame 3 along the sliding direction of the abutment block 4. The abutment block 4 is fixedly connected to the sliding seat 16. The adjusting block 17 is installed on the sliding seat 16 and is cuboid in shape. The adjusting block 17 has a through hole 19 that can be adapted to the hinge rod 15. One end of the hinge rod 15 is hinged to the lifting seat 11, and the other end passes through the through hole 19 and is slidably connected in the through hole 19. The limiting member 18 is used to limit the position of the adjusting block 17. The limiting member 18 includes two adjusting bolts 20. One end of each adjusting bolt 20 is threaded through the sliding seat 16 and can abut against the outer wall of the adjusting block 17 on the side opposite to the adjusting bolt 20.

[0032] Reference Figure 6Through the cooperation of the hinge rod 15 and the adjusting block 17, two synchronous actions can be achieved with a single drive, reducing equipment cost and failure rate. The position of the adjusting block 17 is adjustable, which can adapt to motor 8-shaft blanks of different lengths and diameters. By rotating the fine-tuning adjustment block 17, the travel of the abutment block 4 is changed, improving the versatility of the device. After the adjusting bolt 20 abuts against the outer wall of the adjusting block 17, it can form a rigid constraint to prevent the adjusting block 17 from shifting due to vibration or force during equipment operation, thus limiting the rotation of the adjusting block 17 during use. When changing blanks of different lengths, the angle of the adjusting block 17 can be adjusted by loosening the adjusting bolt 20.

[0033] Reference Figure 2 and Figure 4 A sorting rod 21 is slidably connected to the frame 3 along the transmission direction perpendicular to the conveyor belt 7. A first electric cylinder 22 is fixedly connected to the frame 3. One end of the piston rod of the first electric cylinder 22 passes through the frame 3 and is fixedly connected to the sorting rod 21. Driven by the first electric cylinder 22, the sorting rod 21 reciprocates along the transmission direction perpendicular to the transmission direction to laterally align the blanks on the conveyor belt 7. When the conveyor belt 7 is conveying, the blanks may shift laterally due to placement deviations or inertia. The sorting rod 21 can push the shifted blanks to a unified side to prevent surface damage caused by collisions between the blanks. When the sorted blanks are conveyed to the end, they can abut against the baffle 10 in a unified lateral position, reducing the alignment deviation between the lifting block 5 limit groove 13 and the blank, and reducing the possibility of positioning failure due to blank shift.

[0034] Reference Figure 3 and Figure 5 It also includes an infrared sensor 23 and a controller 24. The infrared sensor 23 is fixedly connected to the frame 3, with the infrared sensor 23 facing the sliding block. The controller 24 is mounted on the frame 3 and is electrically connected to the infrared sensor 23 and each power source, including the second motor 8 and motor 8. When the sliding seat 16 moves the blank to the point where it covers the infrared sensor 23, the controller 24 controls each power source to stop. When the blank is removed and the infrared sensor 23 is exposed, the controller 24 controls the second motor 8 and motor 8 to start according to a preset program. The controller 24 is also used to control the opening, closing and forward / reverse rotation of the first electric cylinder 22.

[0035] Reference Figure 3 and Figure 5 This enables unmanned operation: After the transfer mechanism 2 takes away the blank, the infrared sensor 23 is no longer blocked and sends a "material taking completed" signal to the controller 24. The controller 24 then starts each power source according to the preset program and automatically enters the next round of feeding-positioning process without manual start and stop, thus improving production efficiency.

[0036] Reference Figure 1 and Figure 7The transfer mechanism 2 includes a robotic arm 25 and two pneumatic grippers 26. The two pneumatic grippers 26 are fixed to the actuator end of the robotic arm 25 via connecting seats 27, and their gripping directions are perpendicular. The movement of the robotic arm 25 and the pneumatic grippers 26 is synchronously controlled by the controller 24, which controls the movement path of the robotic arm 25 and the start / stop of the two pneumatic grippers 26. The two pneumatic grippers 26 can work collaboratively: one grips the pre-positioned blank from the feeding mechanism 1 and sends it to the processing equipment; the other grips the processed workpiece and sends it to the unloading table. This eliminates the need for manual movement between the feeding area and the processing area, improving the overall production pace. The perpendicular gripping direction of the two grippers can accommodate the workpiece posture requirements of different workstations without the need to change grippers, thus improving transfer flexibility.

[0037] Reference Figure 1 In summary, the working process of this device is as follows: S1 Initial Preparation: Turn on the power, initialize and preset the parameters of controller 24, and reset each mechanism; manually place the blanks in batches at the starting end of conveyor belt 7. S2 Feeding and Sorting: Controller 24 starts conveyor belt 7 motor 8, conveyor belt 7 conveys blanks; synchronously starts first electric cylinder 22, drives sorting rod 21 to reciprocate, pushes the offset blanks on conveyor belt 7 to the same side for alignment. S3 Blank Positioning: After the blank reaches the end of the conveyor belt 7, it rolls onto the end rod 9 and stops at the baffle 10; the second electric cylinder 12 drives the lifting seat 11 to rise, which in turn drives the lifting block 5 to embed the blank into the limiting groove 13; at the same time, the drive assembly 6 moves the sliding seat 16 and the abutment block 4 together, so that both ends of the blank abut against the abutment block 4 and the abutment plate 14; S4 Transfer and Cycle: After positioning, the blank covers the infrared sensor 23, and the controller 24 stops the movement of each power source; the robotic arm 25 moves with the pneumatic gripper 26 to pick up the blank and send it to the processing equipment; after picking up the material, the infrared sensor 23 is exposed, the controller 24 restarts and resets each power source, and the device enters the next cycle. S5 Special Adaptation: When changing the blank specification, loosen the adjusting bolt 20 to adjust the position of the adjusting block 17, change the stroke of the sliding seat 16, and tighten the bolt to adapt.

[0038] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
